Construction bolts are mainly used in the construction sector, so the quality requirements are relatively high. The building bolts can be used for the knotting between the inner and outer formwork of the wall formwork, to withstand the side pressure and other loads of the concrete, to ensure that the spacing of the inner and outer formwork can meet the design requirements, and also the fulcrum of the formwork and its supporting structure.
The construction bolts are usually made of round steel bolts with two ends of sleeve wire, also known as pull bolts, and wedge-shaped iron with long holes at both ends of flat steel is used to insert fixed wedge, which has a great influence on the integrality, stiffness and strength of formwork structure.
The building bolt can reliably limit the looseness of the nut, but the pin hole position on the screw is not easy to be gentle with the notch of the nut, and the nut may have a small amount of looseness for variable load and vibration, and the construction bolt has a small amount of looseness. The wire for anti-loosening of the wire is continuously passed through a set of radial holes of a set of bolts or nuts, and is impregnated with the wire by the dip-proof, compact structure, and is more complicated to be used for the contiguous structure of the structure.
