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...
