The invention discloses a device and method for installing a vertical air duct without dismantling a wall in a limited space, and the method comprises the steps: assembling two sections of vertical air ducts into a section of combined air duct, and fixedly connecting the four edges of the combined air duct with angle steel; a hoisting system is formed by the winch, the conical counter-force frame and the cross frame to slowly hoist the combined air pipe into the mounting channel until the height of one section of combined air pipe to the hole is reserved; the combined air pipe which is hoisted into the mounting channel is fixed through a reserved hole in the limited space wall body; and the steps are repeated until the whole section of vertical air pipe is installed, and finally the angle steel and the limited space wall body are fixed at the reserved hole in the limited space wall body, so that the wall-dismantling-free vertical air pipe installation in the limited space is realized, the problem that the construction cost is increased due to secondary wall dismantling is effectively avoided, and meanwhile, the construction efficiency is also improved.

    本发明公开了一种用于受限空间下免拆墙竖向风管安装设备及方法,所述方法包括:将两节竖向风管组装成一节组合风管,并在所述组合风管四边固定连接所述角钢;通过所述卷扬机、所述锥形反力架以及所述十字架组成一个吊装系统将所述组合风管缓慢吊装至安装通道内,至留出一节组合风管至洞口的高度;通过所述受限空间墙体上的预留洞口固定住已吊装至安装通道内的所述组合风管;重复上述步骤,直至整段竖向风管安装完毕,最后在所述受限空间墙体上预留洞口处将所述角钢与所述受限空间墙体固定,实现了受限空间下免拆墙竖向风管安装,有效避免了二次拆墙造成施工成本增加的问题,同时也提高了施工效率。
