A prefabricated exterior wall structure based on bim technology

Abstract

A prefabricated exterior wall structure based on BIM technology, including an exterior wall body formed by splicing several exterior wall panels. Adapted positioning slots; a connection plate is provided on the outer side of the exterior wall panel, and a waterproof layer and a decorative layer are sequentially fixed on the side of the connection plate facing away from the exterior wall panel; the side of the exterior wall panel facing the connection plate is installed There are several suspension components, and through holes are opened on the corresponding positions of the suspension components on the connecting plate. On the exterior wall panel, a fragile part is fixed at the end of the through hole away from the exterior wall panel. The invention has the advantages of greatly reducing the difficulty of removing the facing layer during later maintenance, and not easily causing damage to the exterior wall body of the building when the facing layer is removed.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a prefabricated exterior wall structure based on BIM technology. Background technique [0002] BIM technology is an important technology that uses 3D software to plan and integrate information on building design, construction, operation, etc. In terms of prefabricated buildings, external walls are often designed based on BIM technology, and then prefabricated, and then prefabricated wall panels Installation is carried out, thereby realizing the rapid installation of the building. [0003] After the existing exterior wall of a prefabricated building is installed, it is necessary to paste exterior wall tiles on the exterior surface of the exterior wall with an adhesive or cement to form a facing layer. After the building has been used for a certain number of years, the exterior wall tiles on the exterior wall of the building will become loose, and in severe cases, they will ...

AI Technical Summary

Problems solved by technology

After the building has been used for a certain number of years, the exterior wall tiles on the exterior wall of the building will become loose, and in severe cases, they will fall; therefore, it is always necessary to shovel the facing layer on the exterior wall of the building and then re-pave the new finish layer, but the exterior wall tiles that are glued to the exterior wall by adhesive or cement are generally not easy to remove from the exterior wall of the building, thus resulting in a long construction period, and the demolition It is also easy to shovel the outer wall, which will adversely affect the mechanical properties of the outer wall
