Product overview

The material flanging thickness of Yunnan butt fastener is greater than that of hollow rivet, so the tensile strength is increased, and the anti-torque rigidity is greatly improved. Compared with the traditional butt fastener, it is safer and more reliable, and the structural strength of the butt fastener is much better than that of the traditional building fastener. The big end is connected with the upper fastener with notch and thrust surface, and the two sub-fasteners are riveted and rotated at any angle. Make fasteners to reduce the number of parts, butt fasteners have substantial characteristics and significant progress.

The butt fastener must have sufficient strength, durability, and certain elasticity, and effectively maintain the reliable connection between the rail and the sleeper. The use of butt fasteners in building construction can ensure the smooth completion of the project quality during construction. In addition, the fastener system is required to have few parts, simple device and easy assembly. Bowl buckle connection is simple, the domestic commonly used building fasteners cast iron production. Therefore, it can adapt to various planes and facades of buildings and structures with scaffolding compared with economical processing and simple. The small end of the lower fastener in each fastener is connected with the hinge bolt, and the butt fastener consists of two fasteners.

The docking fasteners are fast and light, and the structure is optimized: the fasteners are light, beautiful, comfortable, fast loading and unloading, labor intensity is reduced, work efficiency is improved, and the manufacturing technology is advanced. Due to the use of cold pressing technology, the energy consumption is low in the production process. No pollution, fully in line with the requirements of the national energy saving and emission reduction policy.

Performance characteristics

The cumulative area of bonded sand for butt fasteners shall not be greater than 100 mm². The surface of the fastener is not allowed to have oxide scale. Other technical requirements are in accordance with the provisions of the GB15831-2006.

1. Strong anti-deformation ability. Compared with ordinary steel plate stamping fasteners, due to different manufacturing processes, it breaks through the traditional stamping process's limitation on material thickness (the stamping process can only reach the thickness limit of 3.5mm, and is easy to deform due to insufficient strength in actual use) and reaches 5mm, which can completely ensure no deformation during use, thus ensuring the safety and repeated effective use of the product. The right angle fastener can ensure the good performance and use of the fastener in use, and ensure the normal use of the construction.

2. Strong anti-sliding performance. The slip resistance of the fastener ensures that the steel pipe and the fastener are in a state of bonding surface, and the bonding area is large, which overcomes the shortcomings of point or line bonding between the cast iron fastener and the steel pipe, eliminates the hidden danger of steel pipe slipping, and ensures the use of the steel pipe. Safety effect. The anti-sliding performance of steel pipe fasteners is better to overcome the shortcomings of cast iron fasteners and steel pipes in point or line, and can effectively reduce the errors and safety accidents in construction.

3. Fasteners have safety advantages, quality advantages, and brand advantages. This kind of fastener has good product advantages and can show good advantages during construction. The rental of steel pipe scaffolding is worry-free, labor-saving, and the rental income exceeds the rental of inferior iron fasteners, so the good characteristics of this scaffolding fasteners are more widely used in construction.

4, easy maintenance. Because the fastener itself is not easy to rust and damage, it is very convenient to repair after use, which not only reduces the difficulty of maintenance but also saves maintenance costs, reduces the manpower and material resources of maintenance, and increases the efficiency and quality of construction.

5. Strong anti-corrosion ability. The whole piece is passivated and galvanized double anti-corrosion treatment, its anti-corrosion ability is greatly improved, and the service life is long, far exceeding the service life of cast iron fasteners.

6. Strong anti-stripping ability. With the new connection, the new nut ensures that the fastener can always be firmly fixed vertically when the steel pipe is deformed, eliminating the possibility of steel pipe slipping.
