建筑施工用装配式定型化的线槽和桥架穿墙套管施工技术

Building Construction Technology of Customized-Assembling Slot and Bridge Frame with Wall Bushing

现代建筑功能各式的机电设备被广泛运用,建筑物内配套设置了大量线槽、桥架的穿墙体套管。文中以某传媒大厦施工总承包工程为例,通过采用建筑施工用装配式定型化的线槽、桥架穿墙套管施工技术,不仅解决了套管安装精度问题和预留孔洞尺寸问题,有效保证了套管的垂直度、水平度、牢固度以及防火堵料填塞的密实度,而且进一步提高了套管强度,使套管结构受力稳定、不易变形,确保了建筑物的抗火灾能力和整体安装美观。

Multifunctional electromechanical equipment has been widely applied to modern construction,with a large number of slots and bridges with wall bushing in the building.This paper takes a general contracting project of certain media building project as an example to analyze the building construction technique of customized-assembling slots and bridges frame with wall bushing,which not only solves the problems of wall bushing installation accuracy and reserved hole size,but also guarantees the verticality of wall bushing,levelness and firmness as well as the compactness of fireproof plugging materials.Furthermore,it enhances the casing mechanical strength,ensuring its stability and power equality while not easily deformed,so as to ensure the fire resistance of the building and the esthetic characteristics of the overall installation at the same time.
