Description

Technical Field

[0002] In recent years, various large-scale commercial buildings have sprung up in the construction market, and prefabricated construction has gradually extended to complex equipment rooms, which are where mechanical and electrical installation engineering equipment and pipelines are most concentrated, and prefabrication and assembly are very difficult.

[0003] Prefabricated construction is to combine construction with BIM technology. First, the entire machine room project is modeled in the BIM model, and the pipe installation length, support and hanger position, etc. are measured, and finally a series of complete data are sorted out. Combined with the key technology of digital manufacturing of electromechanical components factory, according to the sorted data, the raw materials are processed in the factory, and the semi-finished products or prefabricated modules are directly transported to the site for assembly. This construction process greatly improves the construction speed, reduces the waste of raw materials, and reduces the input of manpower.

[0004] In the prior art, modular components are prefabricated in a prefabrication plant, and then transported to the construction site, where they are hoisted and installed using hoisting equipment. During the hoisting process, especially when high-rise hoisting is involved, large shaking will occur, which can easily cause collisions between two modular components, resulting in damage to the modular components. In addition, when the modular components are stacked, two modular components cannot be quickly positioned and installed, and the position of the hoisted modular components needs to be constantly adjusted, which is cumbersome to operate and poses a safety hazard. Summary of the invention

After the modular components 1 are placed, the limit assembly 2 is removed, and the hoisting mechanism 3 is controlled to rotate so that the construction platform 5 on the back of the hoisting mechanism 3 faces each modular component 1. The construction personnel evenly apply cement to the joints between each modular component 1 through the construction platform 5, thereby achieving the fixation of each modular component 1. The hoisting mechanism 3 is used to assist in the installation of the modular components 1, thereby avoiding the shaking of the modular components 1 during the hoisting process. At the same time, the limit assembly 2 is used to quickly position and place the modular components 1, which is simple and fast to operate, and improves the construction efficiency. The construction platform 5 is used for construction, thereby eliminating safety hazards.
