Fabricated outer wall structure based on BIM technology

Abstract

The invention relates to a fabricated outer wall structure based on a BIM technology. The fabricated outer wall structure comprises an outer wall body formed by splicing a plurality of outer wallboards. Waterproof flashings are integrally formed at the upper ends of the outer wallboards. The lower ends of the outer wallboards are provided with positioning grooves matched with the waterproof flashings. Connecting boards are arranged on the outer sides of the outer wallboards. Waterproof layers and facing layers are sequentially fixed to the sides, away from the outer wallboards, of the connecting boards. A plurality of suspension assemblies are mounted on one sides, facing the connecting boards, of the outer wallboards. Through holes are formed in the positions, corresponding to the suspension assemblies, on the connecting boards. The suspension assemblies extend into the through holes and are detachably connected with the connecting boards. The connecting boards are suspended on the outer wallboards through the suspension assemblies. Fragile pieces are fixed to one ends, away from the outer wallboards, of the through holes. The fabricated outer wall structure has the advantages that the difficulty of removing the facing layers during later maintenance is greatly reduced, and damage to the outer wall body of a building is not easily caused when the facing layers are 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
