Fabricated curtain wall overall lifting installation construction method based on BIM model construction technical support

Abstract

The invention provides a fabricated curtain wall overall lifting installation construction method based on BIM model construction technical support. The method comprises the steps: carrying out the grid division of a vertical surface of a building curtain wall through the Rhino software technology and three-dimensional setting-out; using MATHCAD calculation modeling software for constructing a structural stress analysis model of a whole single-truss assembled curtain wall aluminum plate steel truss; processing and assembling a single assembled curtain wall truss keel in a production place; re-checking the position where the assembled curtain wall is to be installed, and integrally hoisting the single assembled curtain wall after the re-checking is errorless; integrally lifting and mountingthe assembled curtain wall; and then cleaning gaps between the plates, injecting silicone weather-proof sealant, and finally completing construction of the integrally-assembled curtain wall, and delivering the integrally-assembled curtain wall to be checked and accepted. The construction method is mainly suitable for building curtain wall places with ultra-high, ultra-difficult, large span and short construction period.

Description

technical field [0001] The invention relates to the field of overall hoisting and construction of building curtain walls, in particular to a construction method for overall hoisting and installation of prefabricated curtain walls supported by BIM model construction technology. Background technique [0002] With the construction of large-scale buildings such as commercial centers, cultural and sports centers, convention and exhibition centers, government affairs centers, radio and television media, and transportation hubs in various places, building curtain walls have become an important part of the external display of building shapes, but at the same time, the construction progress and safety of building curtain walls have become the whole The key point of the project is that the traditional curtain wall is generally processed and constructed on site, and the frame material, surface material and auxiliary materials are installed according to the construction drawing and const...
