Installing method for whole-assembling scaffold cantilever

Abstract

The invention relates to an installing method for a whole-assembling scaffold cantilever. The installing method includes the steps that a whole-assembling scaffold cantilever assembly is made, wherein the whole-assembling scaffold cantilever assembly comprises a cantilever beam fastening assembly arranged on an nth shearing wall or a ring beam of a building, an I-shaped steel cantilever beam, a diagonal-drawing-bar fastening assembly arranged on a concrete shearing wall or a ring beam on the periphery of an (n+1)th body of the building, a diagonal-drawing-bar assembly, a scaffold standing-rod positioning device, an I-shaped steel connecting beam and a connecting-beam clamping device; the parts are installed and constructed. According to the installing method, the cantilever beam assembly is delicate and reasonable in structural design and high in bearing capacity, the parts are easy to make, assembling and installing and later disassembling, assembling, recycling and using are convenient, and the reusing rate is high; the installing construction method is rapid, convenient and reasonable, and has the quite-good popularization and application value and the quite-good economic value.

Description

technical field [0001] The invention relates to the technical field of manufacturing and construction methods of building auxiliary equipment, in particular to a method for installing a fully assembled scaffold cantilever. Background technique [0002] The cantilevered I-beam of the outer frame of the existing building scaffolding is generally extended into the indoor end for anchorage and then set up with a safety wire rope for soft pulling. construction methods, but they generally have the following problems: [0003] 1. Waste of turnover materials, the length of the cantilevered I-beam is generally more than 3m, and the U-shaped card anchored at the end is difficult to recycle; [0004] 2. The anchors at the anchoring end usually need to be pre-buried in advance and cut off after completion; the reserved holes on the outer wall need to be sealed after completion, so that the labor intensity of the workers is high and consumes a lot of man-hours; [0005] 3. The reinforc...

AI Technical Summary

Problems solved by technology

[0003] 1. Waste of turnover materials, the length of the cantilevered I-beam is generally more than 3m, and the U-shaped card anchored at the end is difficult to recycle;

[0004] 2. The anchors at the anchoring end usually need to be pre-buried in advance and cut off after completion; the reserved holes on the outer wall need to be sealed after completion, so that the labor intensity of the workers is high and consumes a lot of man-hours;

[0005] 3. The reinforced concrete structure is changed at the shear wall, which affects the quality of the main body of the building;

[0006] 4. There is a common problem of water seepage in the outer wall

[0007] At the same time, when encountering the external corner of the building wall, it is necessary to install a cantilever arranged obliquely at 45°, which requires the installation of connecting beams for reinforcement, but the usual connecting beams are directly welded, which results in time-consuming and laborious construction. Difficult to recycle for reuse
