电梯井道施工中,根据厂家土建图纸要求,井道的顶部都要设置电梯吊钩梁,用来安装及维修电梯,常见的构造做法如图1,2所示。但若土建施工时尚未确定电梯品牌,电梯土建条件图也未确定,电梯吊钩梁该如何设置呢?可以按以下方法施工。将吊钩梁设在电梯机房顶板,两个方向布置均可,但通常设在井道的中间。如果净空高度不够,也可以做反梁,但吊钩一定要用光面钢筋,钢筋的大小按原电梯厂提供的标准荷载吨位由设计按混凝土规范计算得出。
Elevator hoistway construction, according to manufacturers of civil drawings requirements, hoistway should be provided at the top of the elevator hook beam, used to install and repair the elevator, the common construction practices shown in Figure 1,2. However, if the construction of civil construction has not yet determined the elevator brand, elevator civil engineering conditions map has not been determined, how to set the elevator hook beam? You can follow the following method of construction. The hook beam located in the lift room roof, both directions can be arranged, but usually located in the middle of the hoistway. If the clearance height is not enough, you can also do anti-beam, but the hook must use smooth steel, the size of the steel according to the standard load tonnage provided by the original elevator factory calculated by the design according to concrete specifications.
