Problems solved by technology

On the track of the concrete sleeper, due to the poor elasticity of the concrete sleeper, the fastener needs to provide sufficient elasticity. The traditional cross fastener is poor in strength, durability and elasticity, and cannot effectively maintain the reliability between the rail and the sleeper. coupling
In addition, the traditional fastener system has many parts, the installation is complicated, and it is not easy to disassemble

Abstract

The invention discloses a cross fastener, relating to the field of building devices. The cross fastener comprises a heating panel, a front-end fastener and a rear-end fastener, wherein the front-end fastener is connected with a first flange bolt; the rear-end fastener is connected with a second flange bolt; a groove is formed on the front-end fastener; and a bulge is arranged on the rear-end fastener. The cross fastener disclosed by the invention is simple in structure, convenient to use, made of a stainless steel material by pressing, reasonable in design, and optimum in overall mechanical state, as well as has the advantages of having no fracture and deformation, being high in strength, durable, good in fitting performance with a steel tube, good in anti-slide effect via the arrangements of the groove and the bulge, and less in loss.

Description

technical field [0001] The invention relates to the field of architectural devices, in particular to a cross fastener. Background technique [0002] Construction fasteners are used for fastening connections in the construction of steel pipe scaffolding and steel pipe structures for temporary sheds, derricks, and formwork supports. They have the characteristics of small size, assembly and disassembly, convenient transportation, and material saving. [0003] Among them, the cross fastener is an intermediate connecting part connecting the rail and the sleeper. Its function is to fix the rail on the sleeper, maintain the gauge and prevent the vertical and horizontal movement of the rail relative to the sleeper. On the track of the concrete sleeper, due to the poor elasticity of the concrete sleeper, the fastener needs to provide sufficient elasticity. The traditional cross fastener is poor in strength, durability and elasticity, and cannot effectively maintain the reliability be...
