Abstract

The invention discloses an expansion joint shaping mold device and a construction method. The device comprises upper formwork, lower formwork and a steel edge rubber water-stop belt between the upperformwork and the lower formwork. The lower formwork is a right-angled triangular rigid supporting system formed by a welding keel, a formwork face plate, a shear-resistant steel bar hole, an angle steel keel, an inclined strut A, a support and a steel pipe sleeve; the upper formwork is arranged above the lower formwork, the upper formwork and the lower formwork are folded, a face plate and a bottom plate of the upper formwork are fixed through a reserved movable shear-resistant steel bar reserved hole, and the upper formwork and the lower formwork are fixed by tightening tension screws; A U-shaped groove A and a steel edge rubber water-stop belt horizontal positioner are arranged on the angle steel keel of the lower formwork, a U-shaped groove B is formed in the bottom of the target face plate of the upper formwork, and a steel edge rubber water-stop belt is arranged between the U-shaped groove A and the U-shaped groove B. According to the device, shaping and geometric dimension of concrete can be effectively ensured, the position of the steel edge rubber water-stop belt is prevented from displacement, and the shaped expansion joint is smooth and straight and is not bent.

Description

technical field [0001] The invention relates to the technical field of pipe gallery expansion joint construction, in particular to an expansion joint stereotyped mold device and a construction method. Background technique [0002] In recent years, the country has promoted the development of emerging construction fields such as comprehensive pipe corridors and sponge cities to improve the urban living environment. Underground waterproofing projects are the top priority affecting the quality of comprehensive pipe corridors, especially the waterproof needs of the expansion joints of pipe corridors. Pay attention to. Expansion joints need to be set when pouring the foundation floor, but setting expansion joints in general projects will cause many problems, such as waterproof measures can not play a good role, one of the main reasons is that the waterproof membrane is not fixed up to the standard, but also Caused the waste of material, can produce bigger expense with waterproofi...
