Multi-section scaffold with outer-row vertical rods folded inwards in segmented mode and using method

Abstract

The invention discloses a multi-section scaffold with outer-row vertical rods folded inwards in a segmented mode and a using method. The multi-section scaffold comprises a first-section scaffold body, a second-section scaffold body, a cantilever beam and a cantilever layer. The first-section scaffold body comprises a first inner-row vertical rod, a first outer-row vertical rod and a first connecting rod, the first inner-row vertical rod and the first outer-row vertical rod are arranged on one side of the cantilever layer in the vertical direction, the cantilever beam is arranged above the cantilever layer and the first inner-row vertical rod in the horizontal direction, and the first outer-row vertical rod is located on the outer side of the end, away from the cantilever layer, of the cantilever beam. The second-section scaffold comprises a second inner-row vertical rod, a second outer-row vertical rod and a second connecting rod, the second inner-row vertical rod and the second outer-row vertical rod are arranged above the cantilever beam in the vertical direction, the second inner-row vertical rod and the first inner-row vertical rod are located on the same straight line, and the second outer-row vertical rod is located on the side, close to the first inner-row vertical rod, of the first outer-row vertical rod. The upper and lower groups of scaffolds are arranged in a staggered manner to form staggered platforms, so that the safety is improved while the installation is convenient.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a multi-segment scaffolding with outer rows of uprights retracted in segments and a method of use thereof. Background technique [0002] When the superstructure construction of high-rise and small high-rise buildings adopts multi-section cantilevered steel pipe outer scaffolding, the lower section of the shelf is generally disconnected below the overhanging layer, and the overhanging layer erects railings on the outside of the formwork support frame as a safety protection. This protection method has the following deficiencies: (1) The workers operating the formwork support frame and the border protection railings do not have protection construction, and the safety risk is high. (2) After the concrete pouring of the overhanging layer is completed, it is necessary to remove the border protective railings and then erect the upper section of scaffolding, which is labor-...

AI Technical Summary

Problems solved by technology

This protection method has the following deficiencies: (1) The workers operating the formwork support frame and the border protection railings are not protected, and the safety risk is high

(2) After the concrete pouring of the overhanging layer is completed, it is necessary to remove the border protective railings and then erect the upper section of scaffolding, which is labor-intensive and time-consuming

(3) In the process of installing and dismantling the steel cantilever beams of the upper section of the outer frame and arranging the legs of the shelf, there is no safety protection on the air surface, and there is no effective attachment point for the safety belt. Most of them are decorations, and the safety risk of the shelf workers is high

This protection method has the following disadvantages: (1) Since the upper and lower poles are on the same vertical line, before the installation of the upper cantilever beam, the shelf above the cantilever layer needs to be removed, which is labor-intensive and time-consuming; During the process of erecting beams, dismantling them, and arranging shelves, there is no safety protection on the airside, and there are no effective attachment points for seat belts. Most of them are decorations, and the safety risks of shelf workers are high.

It can be seen that both of the above two building methods have the disadvantages of labor-intensive and time-consuming and fail to eliminate safety risks.
