Abstract

The invention belongs to the technical field of civil engineering and mechanical connecting and fastening, and relates to an extrusion type single-side fastening bolt. The extrusion type single-side fastening bolt comprises a thread bolt rod, a sleeve pipe and a spring cushion, wherein a bolt cap is arranged at one end of the thread bolt rod; the spring cushion, a gasket and the sleeve pipe are sequentially arranged on the thread bolt rod in a sleeving way from one end of the bolt cap ; a weak part is arranged in the middle of the sleeve pipe; and a screw thread is formed in the inner surface of one end, far away from the gasket, of the sleeve pipe and meshes with the thread bolt rod. The extrusion type single-side fastening bolt provided by the invention is simple and convenient to operate and fast to install.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and mechanical connection and fastening, and relates to an extruded single-sided fastening bolt. Background technique [0002] At present, in the field of civil engineering construction and mechanical connection and fastening technology, there is a large demand for the installation of structural component connection and fastening. At present, the connection of steel structures can generally be divided into three methods: welding, riveting and bolt connection. Bolt connection is convenient and quick to install, good mechanical performance, suitable for industrial production and other advantages and in line with the requirements of green industrial buildings. The development trend is widely used in the connection of steel structural members. The traditional bolt consists of two parts: the bolt cap and the threaded bolt shaft. When installing, the bolt shaft is inserted into the mounting h...
