Features of steel bar connection sleeve

Features of steel bar connection sleeve: 1. Adopt international No. 45 steel material, special manufacturing process, high dimensional accuracy and reliable quality. 2. It can connect Ф16-Ф40mm HRB335 and HRB400 ribbed steel bars. 3. After passing the inspection of the National Construction Engineering Quality Supervision and Inspection Center, it meets the standard of Class I joints in JGJ107-2010. 4. There are three series of standard type, positive and negative threaded type and different diameter type, and 52 varieties, which can meet the same diameter, different diameter and adjustable length and direction of the horizontal, vertical and oblique parts of the building structure. Connecting reinforcement requirements. Technical characteristics of steel bar connection sleeve: 1. It is suitable for the connection construction of steel bars in reinforced concrete structures of various structures that bear the two-way force of tension and compression. 2. Material saving and energy saving are not limited by the composition and type of steel bars. 3. It can be connected in all directions. 4. It can be pre-made, factory-like operation, no time occupation, and all-weather construction. 5. The operation is convenient and fast, and the construction speed is fast, which can greatly shorten the construction period The technical characteristics of the steel bar connection sleeve The joint strength meets the performance requirements of the A-level joint in the industry standard JGJ107-96. The thread profile is good, the precision is high, and the connection quality is stable and reliable. Wide application range, suitable for diameter 16-40mm. Ⅱ, Ⅲ class steel bar in any direction and position of the same diameter connection. Adjustable type: positive and negative threaded sleeves are suitable for the connection of steel bars that cannot be rotated, such as iron cages. Fast construction speed: thread processing prefabrication and on-site processing, assembly construction. Energy saving, no pollution, safe and reliable construction. The connection method of the steel bar connection sleeve: mechanical connection, sleeve connection, high-rise building application. It is used for the connection and welding of beam reinforcement, welding can have electroslag pressure welding, and flash butt welding electroslag pressure welding is generally used for the connection of column reinforcement The flash butt welding on the top is generally used for beam reinforcement, and it is not allowed to be used in high-rise buildings. Some of them are lap joints. The lap joints are not allowed to appear on the frame columns. The important stress-bearing parts of the reinforcement reinforcement need to be welded, double-sided welding. In the construction industry, traditional steel bar connection methods such as lap joints, welding and other connection methods cannot meet the needs of the rapid development of the construction industry in terms of connection quality, efficiency or operability. The continuous updating of steel bar connecting sleeve technology has led to further innovation and continuous technological advancement of the entire industry. Therefore, the steel bar connection technology is quite successful in a certain sense, and has its own characteristics, so that it can adapt to the continuously developing industry and social trends. The lap connection method can no longer be used for the connection of large-scale steel bars, and welding has many shortcomings, (such as unstable steel material, poor weldability, etc.; unstable power supply or poor welder level; construction period tightness, insufficient capacitance; and weather effects such as wind, rain and cold; and construction plans for places with high fire protection requirements; the quality and speed of on-site connection of horizontal steel bars.) Welding quality cannot be guaranteed. The mechanical connection of steel bars can avoid the above-mentioned difficulties and shows obvious advantages. In the late 1980s, through the introduction of foreign advanced mechanical connection technology, coupled with the continuous efforts of relevant experts in some scientific research institutes in my country, my country's steel mechanical connection technology has developed rapidly. Mechanical connection has gone through different development stages such as sleeve cold extrusion, tapered thread, upsetting straight thread and rolling straight thread.

How to choose a steel bar connection sleeve company?

In construction projects such as buildings, tunnels, and bridges, since the connection method of steel bars has changed from welding to sleeve connection, sleeve production companies have sprung up overnight, and the company's size, production capacity, company reputation, and contract completion ability , product quality, after-sales service and other basic conditions are uneven. What kind of sleeve company should we choose to ensure the construction quality and the smooth completion of the contract? the With the rapid development of network technology and the non-negligible network promotion effect, the vast majority of steel connection sleeve production companies have established their own websites. Open the website recommended by the production and sales company or business personnel to see if it is a simple webpage or a formal website. If it is a formal website, first look at its qualifications, such as whether there are the following certificates and documents: business license for industrial and commercial administration, tax registration certificate, product inspection and testing certificate, organization code certificate, quality management system certification, etc. Whether the unit on the information clearly indicates whether it is consistent with the name of the company, whether it has been inspected annually, whether it is within the validity period, etc., if the company is a member user of Alibaba TrustPass, a user of NetSales, or a deposit user, the above certificates are credible The degree is very high, because if a company wants to become a member user of Chengxintong or Wangshaobao, it must pass the professional qualification inspection of the authenticity of its qualification and the validity of its annual inspection by a professional capital verification agency entrusted by Alibaba. The company only allows it to become a member user of TrustPass or Online Sales Bao, otherwise it does not qualify for membership. In order to further ensure, Alibaba now has to unify on-site certification to verify the company's image, scale, production capacity and quality. the Secondly, it depends on whether the company has been established for more than one year. Such a company has strong stability, rich production experience, strong production quality and contract completion ability, strong technical guidance, and will reduce many unexpected troubles during the construction process. . the Third, ask whether there is professional technical guidance at the construction site during the cooperation. the Fourth, check whether there are any problems with the contract text, whether it can be revised and improved, etc. As for other engineering performance, product display, company profile, sales network, etc., it is only a secondary reference. the Fifth, what needs to be explained here is: Don’t look at whether its product ranks high in a certain search engine, because the ranking is obtained by optimizing the order in which the company’s products appear through bidding promotion, not on the ranking of the company’s products. The result of the quality optimization of the company's products, that is to say, the search engine company only guarantees that its products can be seen by customers as soon as possible, and does not explain the quality of the products. the Sixth, if it is a simple webpage, it is necessary to check which company's products are sold, whether there is a company's authorization certificate, and then follow the clues to check the specific situation of the company. There is no problem in the above aspects, and basically you can cooperate with it. Our Shanghai Hufeng Machinery Co., Ltd. has been welcomed by enterprises since its establishment in 1997. In 2009, it passed the ISO 9001:2008 quality management system certification. At the same time, it was tested by the National Construction Engineering Quality Supervision and Inspection Center (anti-fatigue test, type inspection, etc.). All of them have reached the Class I standard of JGJ107-2010 "General Technical Regulations for Steel Bar Mechanical Connection", and passed the enterprise product standard filing in Shanghai Quality Supervision Department in 2010. In 2011, it passed the audit of the China Academy of Construction Sciences and issued a product certification enterprise certificate. In the same year, it was invited by the China Academy of Construction Sciences to participate in the compilation of the standard "Sleeve Standard for Mechanical Connection of Reinforced Bars". In April this year, we also successfully joined Alibaba TrustPass and passed the on-site certification of the enterprise. We welcome friends from all walks of life at home and abroad to visit and negotiate business and develop cooperation.
