I-shaped steel reinforced beam cantilevered scaffold

Abstract

The invention provides an I-shaped steel reinforced beam cantilevered scaffold, and belongs to the technical field of temporary buildings. The I-shaped steel reinforced beam cantilevered scaffold comprises a steel I-beam with a web at one end provided with a circular opening, a vertical steel pipe with rotating threads at both ends and a keyway type joint socket in the middle, steel plates with two circular openings, a horizontal steel pipe with keyway type joint plugs welded at both ends, nuts with internal rotating threads, and a concrete floor with pre-embedded parts. Vertical displacementis limited by the nuts, and horizontal displacement is limited by keyway type joints and the steel pipes. According to the I-shaped steel reinforced beam cantilevered scaffold, installation is convenient, recycling can be achieved, the stability and security of connection are improved, and meanwhile, the limitation of embedded residue on the space use function is reduced.

Description

technical field [0001] The invention belongs to the technical field of temporary buildings, in particular to an I-shaped steel reinforced beam cantilevered scaffold. Background technique [0002] Scaffolding collapse accidents in the construction industry are becoming more and more prominent. Suspended scaffolding is a commonly used scaffolding in engineering. It is a simple facility used in construction. It is divided into two types: one per floor and multi-layer cantilever. There were no specific industry regulations before, poor conditions in engineering work, large construction errors, etc., resulting in non-standard practices of cantilevered scaffolding and a serious decline in project quality. For example: 1. Two steel bars are welded horizontally on one side on site, there is a small vertical displacement of the cantilever beam after being stressed, the horizontal displacement of the cantilever beam is difficult to control, and the on-site construction quality of the...

Problems solved by technology

There were no specific industry regulations before, poor conditions in engineering work, large construction errors, etc., resulting in non-standard practice of cantilevered scaffolding and a serious decline in project quality

For example: 1. Two steel bars are welded horizontally on one side on site. After the cantilever beam is stressed, there is a small vertical displacement. The horizontal displacement of the cantilever beam is difficult to control. The on-site construction quality of the single-sided horizontal weld of two steel bars is not easy to control.

2. Reinforced with wooden wedges, the wooden wedges will be deformed after being stressed, and the strength of the welded cross bars and door-shaped steel frames is poor

3. A later linking method, the end is fixed by double channels, the wooden wedge is replaced by an iron wedge, and the two-way wedge is used, and there are pre-embedded residues and inconvenience in construction.
