Supporting frame used on construction site

Abstract

The invention discloses a supporting frame used on a construction site. The supporting frame used on the construction site comprises a supporting column and first supporting rods. A second supporting rod is additionally arranged between every two adjacent first supporting rods. Triangular supporting frames are arranged between the second supporting rods and the first supporting rods. The top ends of supporting rods on the triangular supporting frames are welded to the second supporting rods. Bases are fixedly connected to clamping openings. Part of stress of the supporting column is borne by the second supporting rods by means of the stability of triangles, the stability between the supporting column and the first supporting rods is improved, the phenomenon that the supporting column and the first supporting rods become loose due to the fact that the buckling force of the clamping openings is poor is avoided, the safety is improved, and vertical transport operation and horizontal transport operation on the construction site are guaranteed; in addition, aluminum alloy protective covers are arranged on the weld points of the supporting rods and the second supporting rods and can protect the weld points of the supporting rods and the second supporting rods against corrosion in the external environment, and the safety is further improved; and meanwhile, the supporting frame used on the construction site is simple in structure, low in manufacturing cost, high in practicability and remarkable in economical benefit.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a construction site support frame. Background technique [0002] The support frame refers to the various supports erected on the construction site for workers to operate and solve vertical and horizontal transportation. With the increasing maturity and perfection of the Chinese construction market, the bamboo-wood support frame has been gradually eliminated from the construction market, and the construction site support frame is due to It has the advantages of simple maintenance, long service life and low input cost, and has a large development space. The construction site support frame currently on the market is generally composed of a support column and a vertical rod, and then the support column and the vertical rod are fixed through the bayonet, so that the support column and the vertical rod are cross-connected in a grid. Such a structure is easy to disassembl...

AI Technical Summary

Problems solved by technology

The construction site support frame currently on the market is generally composed of a support column and a vertical rod, and then the support column and the vertical rod are fixed through the bayonet, so that the support column and the vertical rod are cross-connected in a grid. Such a structure is easy to disassemble, but during use The following problems occur: the support frame on the construction site has been in the external environment for a long time, and the bayonet is easily corroded, resulting in a decrease in the fastening force of the bayonet, which makes it easy to loosen between the support column and the vertical pole, posing a safety hazard
