Description

Technical Field

[0001] The present invention relates to the technical field of scaffolds, in particular to a modular building construction scaffold and an installation method thereof, and in particular to a modular building construction scaffold and an installation method thereof which are convenient and quick to assemble and disassemble to improve construction efficiency and reduce construction costs. Background Art

[0002] In the modern construction process, in order to facilitate workers to carry out construction at high places of buildings, it is often necessary to set up scaffolding inside and outside the wall. In the past, scaffolding was mostly temporarily built with on-site pipe fittings. Although this method can effectively control costs, it is not convenient due to the primitive bundling and connection methods, and the use effect is not good, which can easily cause complete accidents such as collapse.

[0003] At present, scaffolding is mainly constructed with prefabricated standard rods. There are two main construction modes of scaffolding. One is to connect through connectors, that is, fasteners; the other is to connect through an integrated frame to the wall. Both of the above methods have the problems of low disassembly and assembly efficiency, poor support and large usage volume.

[0004] CN 108149911 B discloses a modular scaffold and a method for erecting the same. A plurality of connecting pipes are connected by connecting pieces through connecting pipes, and finally a scaffold with a limited internal space in a three-dimensional space is formed for operators to stand. In this form, during the erection of the scaffold, the entire scaffold is erected with the connecting pieces as the radiation. However, this method requires the connection and locking of the connecting pieces and the pipes during the erection of the scaffold. The locking method adopted is that each pipe is locked independently with the connecting piece, which is not separated from the previous fastener connection method. This connection method also requires the pipes to be disassembled for storage during use. Therefore, the steps of retracting and releasing are cumbersome, resulting in low efficiency of disassembly and assembly. CN 103321397 B discloses a folding scaffolding, which improves the convenience of the scaffolding by folding a frame forming a parallelogram and storing it. However, the folding structure adopted by the scaffolding relies on a straight ladder for installation and cannot be connected up and down. Therefore, it is subject to height restrictions when used and cannot be used in multi-story construction.

[0005] Therefore, it is of great practical significance to develop a modular building construction scaffold with good applicability and high disassembly and assembly efficiency. Summary of the invention

[0006] Due to the above-mentioned defects in the prior art, the present invention provides a modular construction scaffold with good applicability and high disassembly and assembly efficiency, so as to overcome the defects of the existing construction scaffold that it is difficult to balance high disassembly and assembly efficiency, low construction cost, small storage volume and good applicability.

The number of support channel steels 1 is configured in pairs and arranged in parallel on the ground. A construction scaffold is set on the support channel steel 1. A number of steel bar connectors for fixing the construction scaffold are correspondingly arranged on the support channel steel 1 and inserted into the bottom of the construction scaffold to achieve fixed connection and support for the construction scaffold.

The two connecting rods 21 are the most basic configuration. The two connecting rods 21 are respectively installed on the two axial directions of the fixed connecting member, and are connected with adjacent folding unit frames 2 to form the skeleton of the construction scaffolding together;
