Description
Technical Field
The invention relates to the field of supporting molds, in particular to a post-cast strip supporting mold.
Background
The post-cast strip is a temporary deformation joint reserved in the process of pouring large-area reinforced concrete and is used for overcoming the problem that harmful cracks are possibly generated due to factors such as temperature, shrinkage and settlement when the concrete is integrally poured. After the two parts separated by the post-cast strip are poured and other necessary projects are carried out, the post-cast strip is closed by concrete to connect the buildings into a whole.
For example, in modern building construction, particularly in high-rise building construction, a high-rise main building is often connected with a low-rise skirt building due to functional and styling requirements, wherein the skirt building surrounds most of the main building. In order to avoid the occurrence of cracks in the ground concrete structure caused by the shrinkage deformation of concrete and the settlement difference between the main building and the skirt building, a post-cast strip is correspondingly reserved in the construction of the ground concrete structure, and an existing post-cast strip supporting formwork is usually required to be dismantled, so that the working force is large, and the supporting effect on a casting strip which is cast with concrete firstly is poor. Therefore, it is necessary to provide a post-cast strip supporting formwork to solve the above technical problems.
