Advancing water stop steel bed mould composite structure on post-cast strip

Abstract

The invention discloses an advancing water stop steel bed mould composite structure on a post-cast strip and relates to the field of construction safety. The head water stop steel bed mould composite structure comprises a steel bed mould arranged on the outer side of the post-cast strip and reinforced concrete walls arranged on the two sides of the steel bed mould. The two ends, making contact with the steel bed mould, of the reinforced concrete walls are provided with steps matched with the steel bed mould in thickness. The two ends of the steel bed mould make contact with the steps correspondingly. The outer side face of the steel bed mould and the outer surfaces of the reinforced concrete walls are on the same plane. Three rows of T-shaped connection parts are arranged on the inner side face of the steel bed mould. Each row of T-shaped connection parts comprises a plurality of T-shaped connection part single bodies arranged perpendicularly from top to bottom. One row of T-shaped connection parts is arranged in the overlapping position of one end of the steel bed mould and the reinforced concrete wall on the opposite side and is welded to rebars of the reinforced concrete wall. Flexible waterproof layers are arranged on the joints of the outer side of the steel bed mould and the reinforced concrete walls. The advancing water stop steel bed mould composite structure is easy in material fetching, convenient to machine and good in water stop effect.

Description

technical field [0001] The invention belongs to the field of building installation, and in particular relates to a combined structure of advanced water-stop steel tire boards at post-casting belts. Background technique [0002] The post-pouring belt is a structure often encountered in the construction of high-rise buildings. During the construction here, the concrete on both sides is poured first, and the concrete at the post-pouring belt is not poured. After the concrete on both sides hardens and the structure settles in place, the post-pouring Concrete at the pouring belt. In order to ensure that there is no leakage between the places where the concrete is poured later and the place where the concrete is poured first, water-stop steel plates or rubber waterstops are often placed at the place where the concrete is poured first. However, during the period when the post-cast belt is not poured, there is no concrete and only steel bars at the post-cast belt. If the post-cast ...

Problems solved by technology

However, during the period when the post-cast belt is not poured, there is no concrete and only steel bars at the post-cast belt. If the post-cast belt is in an environment with groundwater, groundwater will continue to infiltrate from here, which will bring great trouble to subsequent construction.
