Movable truss for building construction

Abstract

The invention discloses a movable truss for building construction. The movable truss comprises a fixing disc, wherein a rotating disc is arranged on the inner side of the fixing disc, support rods are arranged at four corners of the lower side of the rotating disc, a fixing plate is arranged on the lower sides of the support rods, a first rotating shaft is arranged in the middle of the upper side of the fixing plate, connecting plates are arranged around the fixing disc, sliding grooves are firmed in upper sides of the connecting plates, the rotating disc and the fixing disc, sliding blocks are arranged in the sliding grooves, a connecting base is arranged on upper sides of the sliding blocks, a supporting plate is arranged on the upper side of the connecting base, drive wheels are arranged at the lower end of the support plate, a third rotating shaft is arranged on the upper side of the supporting plate, a mounting base is arranged on the upper side of the third rotating shaft, fixing rods are arranged at left and right ends of the mounting base, connecting blocks are arranged on outer sides of the fixing rods, a limiting disc is arranged on the lower side of the connecting block at the left end, a counter weight is arranged on the lower side of the connecting block at the right end, and a winding and unwinding roller is arranged on the left side of the lower end of the third rotating shaft. Movement and direction adjustment of the truss can be effectively facilitated by the aid of the sliding grooves, the rotating disc, the drive wheels and the rotating shafts.

Description

Technical field [0001] The invention relates to a construction equipment, in particular to a movable truss for construction. Background technique [0002] A truss is a supporting beam structure formed by connecting rods by welding, riveting or bolts, called "truss". The advantage of the truss is that the rods mainly bear tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save material compared with the solid web beam, reduce its own weight and increase the rigidity. According to the structure, trusses can be divided into triangular trusses, trapezoidal trusses, polygonal trusses, hollow trusses and truss bridges. According to the product type, it can be divided into fixed truss, folding truss, butterfly truss and ball joint truss. [0003] The truss in the current building construction process is generally fixed, so the knowledge of the truss plays a fixed role in the work process, and after people work up and down on t...

AI Technical Summary

Problems solved by technology

[0003] The trusses in the current building construction process are generally fixed, so that the knowledge of the trusses plays a fixed role in the working process, and after people work up and down on the hanging basket, they still need to remove the fixing devices on the trusses and then adjust them. After the orientation is fixed again, the work can be carried out again, which is very time-consuming and labor-intensive.
