Problems solved by technology

The height of the traditional mast cross bar is the same as that of the mast vertical bar. When in use, a mast needs to be installed on the top, which increases the engineering cost. In addition, the existing mast is time-consuming and laborious to assemble up and down, which increases the cost of scaffolding and installation. time

Abstract

The invention belongs to the technical field of scaffolding, and in particular relates to a scaffolding gantry, which includes a gantry vertical tube, a gantry vertical bar, a supporting member and a bottom bar. There are two gantry vertical tubes arranged in parallel at intervals; There are two rods and they are correspondingly inserted in the mast vertical pipe. The upper end of the mast vertical rod protrudes from the upper nozzle of the mast vertical pipe, and a locking piece is provided on the mast vertical rod. Lock its position in the vertical tube of the mast; wherein, when the masts in the up and down direction are stacked, the vertical rod of the mast below is inserted into the vertical tube of the mast above; the present invention uses the vertical pipe of the mast and The gantry vertical bars inserted in the pipe body form a skeleton structure, which has the advantages of simple structure and easy adjustment and assembly; In the vertical tube of the mast frame, it is fixed by the self-weight of the mast frame above, which is simple and convenient, and the steps of fixing and connecting the adjacent mast frames in the upper and lower directions are omitted.

Description

technical field [0001] The invention belongs to the technical field of scaffolding, in particular to a scaffolding door frame. Background technique [0002] Portal scaffolding is a very widely used type of scaffolding for construction. Because the main frame is in the shape of a "door", it is called portal or portal scaffolding, also known as scaffolding or gantry. This kind of scaffolding is mainly composed of main frame, horizontal frame, cross bracing, scaffolding board, adjustable base, etc. Portal scaffolding has the advantages of simple disassembly and assembly, good bearing performance, safe and reliable use, etc., and its development speed is very fast. The height of the traditional mast cross bar is the same as that of the mast vertical bar. When in use, a mast needs to be installed on the top, which increases the engineering cost. In addition, the existing mast is time-consuming and laborious to assemble up and down, which increases the cost of scaffolding and inst...
