AI Technical Summary

Technical Problem

The existing modular steel structure building frame folding device is prone to loosening of the connection between the support column and the hinge seat during transportation, lacks a reliable locking and positioning mechanism, and the outside of the support column is not equipped with an effective reinforcement and protection structure, which affects the overall structural stability and service life.

Method used

The reinforcement and protection component consists of a U-shaped reinforcement plate and reinforcement bolts. The U-shaped reinforcement plate made of EPDM rubber strips and stainless steel is fastened to the column to form a ring-shaped reinforcement structure. Combined with the locking design of positioning screws and screw holes, the stability and protection effect of the hinged joint are ensured.

Benefits of technology

It improves the stability and impact resistance of the articulated joint, prevents wear and corrosion, extends the service life of the device, and ensures flattening of the volume during transportation, thus reducing transportation costs.

Abstract

This invention discloses a modular steel structure building frame folding device that is easy to transport, belonging to the technical field of steel structure building frames. It includes a steel base, a first supporting column, a second supporting column, and a reinforcement and protection component. First hinge seats are linearly arrayed on both sides of the upper end of the steel base. One end of the first supporting column is rotatably connected to the first hinge seat, and the other end of the first supporting column is fixedly installed with a second hinge seat. One end of the second supporting column is rotatably connected to the second hinge seat. A U-shaped reinforcement plate is slidably assembled on the outside of the first and second supporting columns. With reinforcement bolts, the U-shaped reinforcement plate can be firmly fastened to the outside of the columns, providing reinforcement and protection against impact and wear. EPDM rubber strips ensure a tight fit between the U-shaped reinforcement plate and the first and second supporting columns, effectively preventing dust, rainwater, and other impurities from seeping in and avoiding jamming or corrosion at the hinge joints due to impurities.
