Method for reducing lifting weight of precast stair and precast stair structure
The invention discloses a method for reducing lifting weight of a precast stair and a precast stair structure. According to the method, the whole precast stair is divided into a left precast stair plate (1) and a right precast stair plate (1) in the length direction, a male rabbet (2) is arranged in the connection position of one precast stair plate, and a female rabbet (3) is arranged in the connection position of the other precast stair plate; during construction, the precast stair plate (1) provided with the female rabbet (3) is lifted in place by the aid of a tower crane, and then the precast stair plate (1) provided with the male rabbet (2) and the precast stair plate (1) provided with the female rabbet (3) are assembled into the whole precast stair; and thus, potential safety hazardscaused by the fact that the weight of the whole precast stair exceeds the maximum lifting weight of the tower crane are avoided. According to the method and the precast stair structure, the precast stair is divided into the two precast stair plates in the walking direction of the stair, the precast stair plates are lifted one by one during mounting, the technical problem that precast stairs are overweight during lifting in the prior art is solved, the lifting safety of the precast stair is improved, tower cranes having larger specifications are not required to be adopted, and the constructioncost is reduced.
本发明公开了一种减轻预制楼梯吊装重量的方法及预制楼梯结构，本发明是将整体预制楼梯沿长度方向分成左右两块预制梯板（1），并在其中一块预制梯板的连接处设置阳企口（2），在另一块预制梯板的连接处设置阴企口（3）；施工中，采用塔吊先将设有阴企口（3）的预制梯板（1）吊装到位，然后再将设有阳企口（2）的预制梯板（1）与设有阴企口（3）的预制梯板（1）拼接成整体预制楼梯；以防止因整体预制楼梯重量超过塔吊最大起吊重量带来的安全隐患。本发明通过将预制楼梯沿楼梯行走方向拆分为两块预制梯板，安装时逐块进行吊装，解决了现有技术预制楼梯吊装超重的技术问题，提高了预制楼梯吊装的安全性，无需采用更大规格的塔吊，降低了施工成本。
