Strength and toughness of building fasteners
Building fasteners must have sufficient strength, durability, and a certain degree of elasticity, and effectively maintain a reliable connection between the steel rails and sleepers. The use of building fasteners in construction can ensure the smooth completion of project quality. In addition, it is required that the fastener system has fewer parts, simple installation, and easy assembly. The bowl buckle is easy to connect and is commonly made of cast iron for building fasteners in China. Therefore, scaffolding can be used for buildings and structures with various plans and elevations Comparing economy Processing is simple. The lower end of each coupler is connected to the joint bolt, and the building coupler consists of two couplers.
The building fastener consists of two sub fasteners, with the lower end of each sub fastener connected to a joint bolt and the larger end connected to an upper fastener with a notch and a thrust surface. The two sub fasteners are connected by rolling and riveting, and can rotate at any angle. The fastener reduces the cost in design and use, and because the flanging thickness of its own data is greater than the thickness of the blind rivet, it increases the tensile strength and greatly improves the torque resistance rigidity. Compared with the traditional building fastener, it is safer and more reliable. The structural strength of the building fastener is much better than the conservative building fastener.
Building fasteners have substantial characteristics and significant progress, which reduces the number of parts and costs of fasteners. Moreover, because the flanging thickness of its own material is greater than the thickness of hollow rivets, it increases the tensile strength and greatly improves the torque resistance rigidity. Compared with traditional building fasteners, it is safer and more reliable. The structural strength of this building fastener is much better than that of traditional building fasteners. The large end is connected to the upper fastener with a notch and a thrust surface, and the two sub fasteners are riveted and rotated at any angle. Reducing the number of parts in fasteners, building fasteners have substantial characteristics and significant progress.
