Based on the actual situation of the development of the current social construction industry, it is not difficult to find that in recent years, the steel rolling straight thread connection technology has been gradually promoted and applied in China’s urban and rural construction projects because of its own economical and reasonable and reliable quality characteristics. Through the observation of the actual situation of construction, it is found that the technology plays an important role in ensuring the quality of engineering construction, so it is necessary to conduct feasibility studies on the technology to promote the effective implementation of construction.

1 The advantages of rolling straight thread connection technology for reinforcing bars

In the actual construction process, the rolled straight-threaded connection technology is based on its simplicity and reliable quality, and the actual stable operation of all aspects of the connection facilitates the realization of the purpose of the connection. In terms of construction specifics, the rolled straight thread connection technology has the following advantages.

It is relatively easy to operate during the construction process, and the technology is non-polluting, non-open flame, and relatively safe to operate. The strength of the joint is high and the tightening force does not affect the performance of the joint too much, and the quality of the rebar threads meets the national standards and the processing accuracy is high, which makes the quality of the rebar connection reliable. From these two aspects, the technology does not easily affect the construction quality, and to a certain extent promotes the improvement of the construction quality to meet the relevant standards.

The reliable connection quality of this technology and the relatively good fatigue resistance of the joints in the actual application process make it widely applicable to reinforced concrete construction structures under various environmental conditions, which are usually not affected by the construction environment and climatic conditions, and the construction site environment is relatively neat and clean, with relatively little noise pollution and smoke pollution, thus helping to protect the health of construction personnel.

The construction quality of the straight threaded rolling connection technology is easy to control, and is not easily affected by human factors and the external environment. Usually, the exposed wire buckle is within two turns to reduce the safety risks.

2 The practical application of rolling straight thread connection technology for steel bars

　　2.1 Construction process

The upsetting straight thread process is to first use the cold heading machine to upset the end of the steel bar, then use the sleeve machine to process the straight thread on the upsetting section of the end of the steel bar, and then use the connection cylinder to butt the two bars. By ten steel bar end cold heading, not only the cross-section is increased; but also the strength is improved. Plus, the minimum diameter of the bottom of the thread after the straight thread is processed on the end of the steel bar, should be not less than the diameter of the parent material of the steel bar. Therefore, the joint can be equal strength to the parent material of the steel bar.

The connection process of equal-strength straight-threaded reinforcement follows the standard process of construction and should not be changed at will in order to affect the actual quality of construction. In the construction process, there is inevitably cutting of the material, so the processing of the reinforcement should be scientifically and reasonably adjusted to ensure that it meets the construction specifications and standards. In particular, in the process of reinforcement upsetting, the operation should be standardized by professional equipment, and the most suitable processing pressure should be determined by conducting trial processing according to the relevant data and possible influencing factors before the formal processing.

The operation should be standardized, the processing angle should be carefully mastered and carefully checked in order to promote the actual effect of upsetting to be reliably guaranteed. It should be noted that in the actual construction process, it is strongly not allowed to upset the original upsetting reinforcement again. If it is found that the quality and effect of the upsetting reinforcement does not meet the relevant requirements, it needs to be cut out and reapplied to the upsetting operation.

In the thread processing, the threads are added one by one on the special thread sleeve machine and matched with the matching sleeve one by one, and those that pass the inspection go to the next process, and any qualified threads are removed. In order to ensure that the threads are damaged or operated during installation and transportation, they should be protected by sleeves or plastic caps in time.

In the process of steel connection, the connection sleeve is prefabricated in the factory according to the design specifications and accuracy and then boxed for use. In the field, the connection sleeve is used to connect the reinforcing steel and tighten it with a common wrench. In operation, attention should be paid to the degree of tightening, in general, the reinforcement joint without more than one buckle of the complete wire buckle exposed can be considered tightened.

　　2.2 Material and machine equipment

①Steel should meet the requirements of the national standard “hot-rolled ribbed steel for reinforced concrete” (GBl499) and the requirements of the “remaining heat-treated steel for reinforced concrete” (GBl3014).
② sleeve and locking mother material should be used high-quality carbon steel or alloy structural steel, the material should comply with the provisions of GB699.
③Tools and equipment: cutting machine, wire snapping machine, common wrench, gauge, etc.

　　2.3 Quality control and precautions

①Personnel participating in the construction of rolling straight threaded joints must have technical training and pass the examination before they can be licensed to operate.
②The end face of the reinforcing bar must be flat, and the material should be cut with an abrasive cutter. The end face should be bent and the horseshoe should be cut away to avoid damaging the cutter and affecting the quality of the fillet during processing. ③Steel processing should often add water-soluble cutting fluid, it is strictly prohibited not to use cutting fluid processing fillet.
④Steel to be processed must be tied to a good identification plate to avoid processing the wrong model. ⑤ The end of the wire head should wear a protective cap in time after processing and inspection to prevent the wire head from being damaged or contaminated by cement paste in the process of handling and installation construction. ⑥Check the length of the thread, the fullness of the thread type and the number of complete threads in the process of processing.

　　2.4 Connection and inspection of straight threaded joints

2.4.1 Field connection of straight-threaded joints.
①When connecting reinforcement, the specifications of the reinforcement and the sleeve must be the same, and the fillets of the reinforcement and the sleeve must be clean and intact.
② When connecting reinforcement, the reinforcement should be screwed into the connection sleeve on the positive axis.
③After the connection is completed, the two threads should be tightened in the central position of the sleeve and the standard sleeve should not have more than one buckle of complete wire exposed at each end.

2.4.2 Quality inspection of straight-threaded reinforcing steel joints The performance inspection of straight-threaded reinforcing steel joints is divided into two categories: type inspection and construction site inspection, sleeve inspection for factory inspection and fillet inspection for processing site inspection. The type inspection includes one-way tensile, high strain repeated pulling and pressing, large deformation repeated pulling and pressing of strength, ultimate strain and residual deformation.

At the construction site, the appearance of straight-threaded steel joints should be checked in full according to the national standard “General Technical Specification for Mechanical Connection of Reinforcing Steel” (JGJl07), and the mechanical properties of straight-threaded steel joints should be tested by taking specimens. One-way tensile test, if a test piece fails, then double the sampling, that is, take 6 test lines for re-inspection, if there is still a test piece fails, then the acceptance batch is unqualified. With the rapid development of construction projects, rolling straight thread connection technology for steel reinforcement has enhanced the safety factor for a new generation of mechanical connection technology.

Conclusion

With the development of social economy and the progress of science and technology, the rolling straight thread connection technology has been more widely used in the construction of building construction, because of its own convenient operation, good joint strength and other advantages, the construction industry has received widespread attention. From the perspective of the actual situation of the construction of today’s situation, it is important to strengthen the practical application of the rolling straight thread connection technology for the long-term development of the construction industry.

Therefore, it is necessary to analyze the actual application of this technology to help promote the continuous improvement and development of this technology on the basis of the current development, so as to better play its actual value, promote the scientific and effective development of the construction industry, and overall promote the progress of the social economy.

Perform an ABC evaluation, a straightforward, common and effective tool for inventory management. It is primarily based on Pareto’s law of “80-20.” The most typical approach is to calculate demand in units, preferably for future periods, then calculate the total usage value at price for each and every item (total price of sales multiplied by units needed) for a given future period. If future demand data are not obtainable, the next ideal issue is to use history, but this will not work properly for things with main swings in demand over time. Sequence these in descending worth. Generally, the prime 10 to 15% of products account for 75-85% of worth (“A” products), the next 20-30% account for ten-20% of value (“B” things) and every little thing else accounts for the rest, about 60-70% of the things, usually about five% of the total worth (“C” items). Your inventory need to be less than these percentages for the “A” products, since they are significantly more tightly controlled and a little larger for B’s and significantly larger for C’s. Union Unique, Germany, introduced several machines for seamless garments amongst these a special flat seaming machine with 4 needles thread feed off the arm with leading cover thread for overlapped joining processes. The photocell controls the thread-chain-cutter at the back of the foot-presser. Educate and train people in inventory management and manage approaches. By producing a team that includes Marketing and advertising, Style Engineering, Accounting, Manufacturing Engineering, Getting, Materials, Industrial Engineering and Produc­tion, a synergy is designed. Synergy is an power for creativ­ity and efficiency that is bigger than the sum of its parts. In this process all the specialists work with each other from the starting to bring a unique, quality item from notion to market in much less time and at a competitive expense. If demand for your organization’s items or solutions is lowering, in order to keep revenues healthier, it becomes even far more critical to drive organizational overall performance to boost your share of a shrinking market. In a competitive marketplace, organizations need to have to be agile, to reduce method inefficiencies and to enhance effectiveness across the company. Successful employee communications plays a vital part in reaching these ambitions with an investment that’s modest compared to worth gained. Very good employee communication is a competitive benefit. We’ve in no way completed anything like this prior to. Everybody on the project operates in one large space, from the designers to the engineers to the accountants and the production provide folks. 19. Pro Photographer – If you take a image that is what you get, a picture. But by syncing your GPS tracking device’s info with your pictures you have photographs with extra info such as time, date, place and significantly a lot more attached in the picture’s meta-information. When you have thousands of pictures to catalogue this could effectively be helpful. Barcode technologies coupled with asset management application allows construction material coming into a web site to be tagged and the tag ID used to find where on the website the material has to be stored. This technologies has the potential to speed up delivery of material to the point of use. Making use of smartphone technologies, this can be achieved with a simple series of barcode scans, from a device that you currently use in your each day enterprise. In some cases, a rugged device will be most acceptable for building environments.

of the leak is and make essential repairs. Even if you don’t have a leak, a licensed plumber can examine your galvanized pipes to advise you on whether they are responsible for any plumbing points you could be experiencing. The corrosion and deposits which type inside the pipes over time lower the obtainable area contained in the pipe, which eventually lowers the water stress in your house. PVC plastic pipes are also utilized in houses as a result of they’re easy to put in and don’t rust or corrode.

​When you’re dong slicing the pipe, the perimeters of the galvanized metal could also be rough from the blade​. The hacksaw will probably depart it the roughest out of any of the choices, however you’ll need to perform a little bit of work to finish it off either way. You’ll additionally in all probability be left with an excellent quantity of sanding to do to easy the steel pipe out. Simply fasten the pipe cutter over the world you’re cutting, and tighten it over the steel. Spin the cutter around the pipe in circles, allowing the device to slowly chop its means via the steel. You may be succesful of get away with chopping this sort of pipe with areally highly effective jigsawthat has thecorrect bladeon it.

Galvanized pipe fittings are lined with a layer of zinc which makes these fittings have higher capacity of corrosion protection and assist to prevent the buildup of mineral deposits that may block the pipe. Galvanized pipe is mainly used for carrying water to provide residence and industrial buildings; it might also function scaffolding frames because of its rust prevention. Galvanizing can also shield metallic through a course of known as “galvanic corrosion”. Galvanic corrosion happens when two metals of a unique electrochemical make up are positioned into contact with each other with an electrolyte current, such as salty water. Depending on the atomic construction of the two metals, one metallic is the anode and the opposite is the cathode. The anode corrodes extra rapidly than it would by itself and the cathode corrodes at a slower pace than it will by itself.

If galvanized pipes are used and want to have them eliminated and changed, our plumbers will re-pipe your plumbing system. Stainless steel, rather, is a time period that describes steel that has been mixed with at least 10% chromium. This amalgamation of metals makes stainless-steel particularly resistant to mineral decay and age.

The leak distance and the position of the pipe fault can be organized to repair the manpower. The value of those metals has jumped since Russia invaded Ukraine, fearing that Western sanctions or logistical difficulties ensuing from the battle might choke off the supply. On Friday, nickel traded at its highest level in a decade and is up 37% so far this year.

These pipes could be changed using CIPP and sliplining that dramatically enhance the lifespan of the pipe without eradicating them. Cross-linked polyethylene pipes got here to the fore in the 1950s as conduits in radiant floor heating techniques. Over the previous 20 years, nonetheless, PEX pipes have been repurposed for water distribution methods. Our showrooms display the most recent kinds in kitchen, tub and lighting design from business leaders.

Although there are advantages to using galvanized steel, your plumbing problems may be linked to these sorts of pipes. Learn extra about why you might must upgrade your home’s plumbing, how long galvanized pipes final, whether or not these pipes comprise lead and tips on how to determine which type of plumbing you’ve. The joints connecting galvanized steel pipes are threaded, and they can be unstable and vulnerable to leaking and rusting. This exposes the metallic beneath and hastens the corrosion course of.

This response permits the steel or iron steel floor to bond with the zinc, making a protective layer. This layer allows for defense towards rust and will increase the lifespan of the pipe. This layer of protections helps defend it from the skin elements and the materials running by way of them. Homes constructed many years ago were saved to completely different laws compared to residences and buildings built right now. Houses built during the Sixties and prior had been frequently outfitted with galvanized sewer/water pipe techniques. These metal pipes were coated in a layer of zinc to broaden their powerful life span.

For manufacturers that have to hold really tight tolerances on their parts, tactile measurement often is their only indicates of very correct measurement. Given that the introduction of the 1st laser scanners in the late 1970s there has not been a enormous, chasm-crossing breakthrough in the accuracy of noncontact laser scanners that would let makers of tightly dimensioned parts to abandon classical touch-trigger and analog scanning approaches. The standard 3D “bridge” CMM makes it possible for probe movement along three axes, X, Y and Z, which are orthogonal to each and every other in a three-dimensional Cartesian coordinate method. Each axis has a sensor that monitors the position of the probe on that axis, generally with micrometer precision When the probe contacts (or otherwise detects) a distinct place on the object, the machine samples the 3 position sensors, as a result measuring the location of one point on the object’s surface, as well as the 3-dimensional vector of the measurement taken. This procedure is repeated as needed, moving the probe each time, to make a “point cloud” which describes the surface areas of interest. From Mr. Berry’s perspective, a coordinate measuring machine never made sense. Inspecting a part right after machining adds no value, he says. Alternatively, when the shop lastly did get a CMM, it was for inspection before machining. Especially, all EDM electrodes in the shop—hundreds of electrodes per week—now pass across a non-speak to laser scanning head from Nikon Metrology, mounted on a Brown & Sharpe CMM.

The special and totally integrated metrology method measures the virtual world first, and adapts the genuine planet to fit. This intuitive program is referred to as Adaptive Robot Control , as it tends to make the robot intelligent adequate to make its own adaptations. This implies that the robot can accurately compensate for robot deformation (under dynamic load), temperature fluctuations and mechanical play. The metrology method tends to make the robot conscious of deflections by measuring the relative positions of the target and the robot as it moves toward it. The robot is in a position to coordinate that information on-line and make the needed compensations instantaneously. An additional task of these CMMs is to guarantee the accuracy of geometric pallets on which the automobile bodies are assembled. Previously, verifying that the pallets had been inside tolerance was carried out in an off-line CMM facility and entailed taking them out of the body-in-white line at weekends to avoid disrupting production. The history of Nikon Metrology (formerly Metris) with metrology-assisted production goes back seven years. We first developed integrated laser systems that included metrology for composite material layup and verification. That program grew into a guidance tool for manual assembly processes,” says Jarrad Morden, common manager of Nikon Metrology Canada. Their custom-built, integrated systems use a variety of metrology instruments, such as Nikon Metrology’s indoor GPS (iGPS) technologies, to align 1 or more laser projectors precisely to a portion, tool, or surface. Now a simpler approach of monitoring accuracy at typical intervals among the annual checks, or soon after a collisionis available. Using the Renishaw Machine Checking Gage (MCG), its now possible to carry out a 10-20 minute automatic verification of volumetric accuracy to ISO 10360-two. The results provide assurance that measurements taken on the CMM are precise, or give conclusive proof that servicing or re-calibration work is needed. The approach is swift and price effective and the technique gives for a range of pillar heights and arm lengths mean that volumetric accuracy can be checked on both massive and small CMMs. AMF Reece, primarily based in Czech Republic, introduced a chain stitch buttonhole lingerie tucker machine, 5-4000 LT, to boost finishing process of the flat seams and flat lock seams. The surplus flat lock seam is absorbed through the sensor control. The flat seam is cut and totally sewn on, and then cut-off flat lock chain is thrown into the squander. The Nikon Metrology laser scanner-primarily based inspection system enables Balda to get a detailed view of dimensional errors in very first report mobile telephone casings in a very brief time. The components are digitized making use of a laser scanner that captures about 20,000 points per second. The dense digital copy of the physical part is aligned and compared to the reference CAD model to detect and analyze the issue areas in a quite quick time. The pointcloud model and reports are delivered to the mobile telephone OEM as portion of an improved top quality approach, to avoid in early stage, any attainable error.
