Edge hole finalization type railing and construction method thereof

Abstract

The invention provides an edge hole finalization type railing and a construction method thereof. The edge hole finalization type railing comprises upper cross rods, lower cross rods, longitudinal rods and screw rods, wherein the two ends of the longitudinal rods are separately and detachably connected with the upper cross rods and the lower cross rods, and the two ends of the upper cross rods and the lower cross rods are hollow, and the upper cross rods and the lower cross rods are connected with the screw rods. The screw rods are provided with nuts, the other ends of the screw rods are connected with reserved mounting holes in the edge hole, the lower ends of the longitudinal rods are connected with toe boards, the interior of the toe boards is hollow, and weight materials are put into the toe boards, so that the stability of the whole device is increased. The edge hole finalization type railing is high in finalization, convenient to install and disassemble and firm and reliable, the subsequent construction progress is not affected, the high safety factor is achieved, the construction efficiency can be improved, labor is saved, the edge hole finalization type railing is convenient to turn over and convenient to store and transport after disassembling.

Description

technical field [0001] The invention belongs to the technical field of high-rise construction of industrial and civil buildings, and in particular relates to a stereotyped railing and a construction method for a border opening. Background technique [0002] At present, in the field of high-rise construction of civil construction, there are many side windows and openings during the construction process, and their shapes are mostly rectangular, but there are differences in the width of the openings. After the attached lifting scaffolding is moved up, two horizontal protective railings with heights of 600mm and 1200mm are often fixed on the indoor wall during construction, and a 200mm footboard is set at the bottom. This operation generally uses a nail gun to shoot nails or expansion bolts to fix the effective connection card. Ring, and then effectively connect the steel pipe and the footboard to the snap ring fixed on the wall, or use ordinary shaped railings to use a nail gun...

AI Technical Summary

Problems solved by technology

During the construction, if the nail gun and the expansion bolt are installed to meet the reinforcement in the wall, the effective depth of the penetration into the wall may not be enough, the force cannot meet the requirements, the safety guarantee factor is low, and the concrete wall with less reinforcement is easy to be replaced. Surface damage will affect the force of the main structure and the appearance of the surface

Generally, the protective device is only fixed on the two side walls, and the structural stability is poor, and small pieces of construction waste and construction tools are easy to fall out of the edge hole through the lower part of the protective device, causing accidents

The use of nail guns and electric drills during the operation produces loud noise, vibration and dust, which is not conducive to the construction of workers and easily affects the surrounding residents

The wall nails and expansion bolts are not easy to remove, and the expansion bolts even need to be chiseled before they can be removed. Some construction workers do not have a strong sense of responsibility, and even refuse to remove them. If they directly carry out subsequent process construction on this basis, it is easy to cause the part to return. rust, so the requirements for the overall quality of the operators are also high

Due to the different sizes of the holes, the cutting volume of the steel pipe is relatively large, which has a great impact on the later reuse of the steel pipe

At the same time, this method of fixing on the interior wall has a great impact on plastering, puttying and window frame installation, resulting in a large area of ​​process retention. If this part is constructed, the protective measures will be removed, which will seriously affect the safety of personnel.
