Connection method of anti-displacement adjustable structural member with double external teeth

Abstract

The invention relates to a connection method of an anti-displacement adjustable structural member with double external teeth, which is characterized in that the connecting member used comprises a pre-buried channel with a C-shaped cross section, an anti-displacement tooth plate, a T-shaped bolt, a shock absorbing pad, a spring washer and nuts, wherein the outer side of the two walls of the notch side of the pre-buried channel is provided with teeth; the anti-displacement tooth plate is a rectangular or square pad with a bolt hole perpendicular to the plate surface, and the teeth are arranged on the plate surface; the pre-buried channel is poured into the concrete foundation, the head and the shock absorbing pad are placed in the groove of the pre-buried channel after the shock absorbing pad is sleeved on the screw of the T-shaped bolt, and the anti-displacement tooth plate, the structural member to be fixed and the spring washer are sequentially mounted on the screw of the T-shaped bolt, so that the teeth of the anti-displacement tooth plate mesh with the teeth on the pre-buried channel, which is finally fastened by nuts. The method has the advantages that the structural member canbe fixed more firmly and reliably, and the displacement resistance and the shock resistance are stronger.

Description

technical field [0001] The invention relates to a method for connecting adjustable structural parts with double external teeth anti-displacement, and belongs to the technical field of fixed connection of structural parts. Background technique [0002] In the field of engineering, there are many structural parts that need to be connected and fixed, such as: in high-speed rail, subway and other rail transit, it is used for the fixing of catenary, communication signal, and power equipment, the fixing of cable bridge ladders in bridges and tunnels, and the pipe line in urban pipe corridors Support and fixation of cables, fixation of elevator rails in elevator shafts, fixing of cables and power pipelines in nuclear power plants, fixing of curtain wall brackets, pipeline cables and communication cables in curtain walls and buildings. With the development of China's rail transit and construction industry, the technology of toothed pre-embedded grooves is popularized, and the toothe...

Problems solved by technology

However, with the increasing application of internal tooth embedded channels, some shortcomings have been exposed. When the internal tooth embedded channel and T-bolt connection are subjected to pulsating loads, their occlusal surface anticorrosion layer will gradually be destroyed. , and the contact surface is quickly corroded under the action of a humid environment. As the corrosion increases, the bearing capacity of the embedded channel gradually decreases, which greatly increases the incidence of accidents and brings hidden dangers to life and property.
