Light prefabricated stair
The invention relates to the field of prefabricated staircases, in particular to a light prefabricated staircase which comprises a staircase body, a weight reduction cavity is formed in the staircase body, a material injection opening is formed in the staircase body and communicates with the weight reduction cavity, a filling material is arranged on the staircase body, the filling material enters the material injection opening through a material injection part, and the staircase body is transported to a construction site and installed. And after installation is completed, filling materials are injected into the weight reduction cavities through the material injection openings, and the structural strength of the prefabricated staircase is improved. And by forming the weight reduction cavity in the stair body, the weight of the prefabricated stair can be reduced in the transportation and installation process, and the prefabricated stair can be transported and installed more easily and conveniently.
本申请涉及一种轻质预制楼梯，涉及预制楼梯的领域，包括楼梯本体，楼梯本体中开设有减重腔，楼梯本体上开设有注料口，注料口与减重腔连通，楼梯本体上设有填充料，填充料通过注料件进入注料口内，将楼梯本体运输到施工场地并安装，安装完成后，通过注料口向减重腔内注入填充料，增加预制楼梯的结构强度。通过在楼梯本体中开设减重腔，有利于降低运输和安装过程中，预制楼梯的重量，使运输和安装预制楼梯更加轻松便捷。
