The utility model belongs to the technical field of rail transit engineering, and specifically provides a floor hanging prefabricated water catchment well structure, including a mid-plate and a well body. The edge of the mid-plate is provided with a hole side beam, and the hole side beam is connected with the well body through bolts. By first constructing the Mid-slab of the station, reserving the hole side beam in the mid-slab, embedding bolts or reserving bolt casing in the hole side beam, and then connecting the prefabricated well body with the cast-in-situ Mid-slab hole side beam through bolts, the construction period of the main body of the station is shortened, and the main body of the station is covered with soil and the road surface is restored as soon as possible. A rubber water stop belt is set between the prefabricated well body and the cast-in-situ plate beam, and the seam is treated to effectively prevent the leakage of the seam. The structure has the advantages of simple design, convenient construction, saving investment and guaranteeing the construction progress of the main body. It has good application prospects in the field of Metro structure construction.

一种楼板吊挂预制集水井结构
本技术属于轨道交通
,具体涉及一种楼板吊挂预制集水井结构。
技术介绍
风井是建筑中预留的通道,主要用于通风或者防水,危急时刻也可用于逃生与消防。地铁车站内的风井或出入口从顶板直接顶出有利于减小车站规模,充分利于地下空间,减小对周边的影响等。地铁设置顶出结构,雨水会落入中板,常规做法是在中板设置集水井汇集雨水,中板在集水井井口边设置孔边梁挑住集水井。在实际施工中,集水井与中板一起施工,支架模板需要在集水井处下沉,不利于支架模板标准化施工,且增加车站主体施工周期。
技术实现思路
本技术的目的是克服现有技术中集水井施工周期长且施工难度高的问题。为此,本技术提供了一种楼板吊挂预制集水井结构,包括中板和井体,所述中板边沿设有孔边梁,所述孔边梁与所述井体通过螺栓连接形成集水结构,井体边沿设有井壁耳板,所述井壁耳板设有通孔,所述孔边梁内预埋有螺栓套管,所述螺栓穿过所述通孔并与所述螺栓套管螺纹配合。优选地,井体边沿设有井壁耳板,所述井壁耳板设有通孔,所述螺栓的头部预埋在孔边梁内,所述螺栓的螺杆贯穿所述通孔并通过螺母配合。优选地,井体边沿设有通孔及手孔,所述螺栓的头部预埋在孔边梁内,所述螺栓的螺杆贯穿所述通孔抵达手孔并通过螺母配合。优选地,孔边梁内设有贯穿孔,所述螺栓的头部预埋在井体边沿,所述螺栓的螺杆贯穿所述贯穿孔并通过螺母配合。优选地,孔边梁内设有贯穿孔,所述井体边沿预埋有螺栓套管,所述螺栓穿过所述贯穿孔并与所述螺栓套管螺纹配合。优选地,孔边梁内与所述井体的接触面设有橡胶密封垫。优选地,孔边梁内与所述井体的接触面缝隙嵌有聚硫密封胶。本技术的 ...
