Fabricated building construction method based on BIM technology

Abstract

The invention discloses a fabricated building construction method based on a BIM technology. The fabricated building construction method comprises the following steps that S1, outer wall plates and laminated plates are prefabricated, and guide rails are installed on the surfaces of the outer wall plates through bolts; S2, a foundation pit is excavated, an underground building structure is completed, a surface layer is poured, and connecting steel bars are reserved on the upper surface of the surface layer; S3, lifting equipment is prepared, and a tower crane is built on the ground; and S4, the outer wall plates are hoisted through a hook of the tower crane, the lower surfaces of the outer wall plates are in lap joint with the upper surface of the surface layer, a wall body inclined support is installed, the perpendicularity of the outer wall plates is adjusted, and the outer wall plates are connected and reinforced through the connecting steel bars and a grouter. The lifting equipment is used for lifting the outer wall plates, the outer wall plates are stacked in the vertical direction, so that the guide rails on the surfaces of the outer wall plates are aligned, the lifting equipment ascends along the guide rails and moves layer by layer, the function of transferring the outer wall plates is achieved, the lifting equipment can serve as a workbench for outer wall installation, the workbench does not need to be set up layer by layer, and construction is convenient.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a BIM technology-based construction method for a prefabricated building. Background technique [0002] At present, the country vigorously advocates the development of prefabricated buildings and BIM technology. With the continuous advancement of prefabricated construction projects, environmental pollution has been reduced and the healthy and sustainable development of the construction industry has been promoted. Due to the discovery during the construction process, there are many project data and difficult Quickly save the query, the poor coordination among the participating parties, the low level of simple text visualization, and poor sharing. Therefore, introducing BIM technology into the construction organization design of prefabricated buildings can ensure the orderly progress of the construction site and promote the construction of prefabricated buildings...

Problems solved by technology

[0003] Prefabricated buildings are assembled directly on the construction site with prefabricated components in the factory, mainly by hoisting machinery, but the connection and fixation between components need to be carried out manually, and high-altitude operations are often carried out, which has many potential safety hazards, especially It is the hoisting of building exterior wall panels. When the components are fixed manually, the working space is limited, and the construction period is delayed by the construction of the working platform. In the assembly of multi-storey buildings, it is time-consuming to build the working platform layer by layer. To solve this defect, the present invention proposes a A prefabricated building construction method based on BIM technology
