Description

Independent supporting device for post-cast strip template

Technical Field

The utility model belongs to the technical field of the construction of post-cast strip, concretely relates to independent strutting arrangement of post-cast strip template.

Background

The post-cast strip is a concrete strip reserved at the corresponding position of a foundation slab, a wall and a beam according to the design or construction specification requirement in order to prevent harmful cracks possibly generated by uneven self shrinkage or uneven settlement of a cast-in-place reinforced concrete structure in the building construction. At present, relevant specifications stipulate that the template and the support of the post-cast strip of the reinforced concrete structure can be detached only after concrete pouring at the post-cast strip is completed and the strength meets the stripping conditions. Because the template and the supporting device at the post-cast strip are independently supported, a quite large working surface is still required, and the template and the supporting device are still required to be connected with a large-area template and the supporting device, so that the overall strength, rigidity and stability of the template and the supporting system are ensured. Because the template and the support are arranged to ensure enough strength, rigidity and stability, the plate seam and the support joint need to be staggered, the construction is complicated, and the plate seam and the support joint cannot be completely disconnected. The bottom of the post-cast strip plate and the bottom beam plate are not detached, so that garbage at the joint of the post-cast strip cannot be thoroughly cleaned, the quality defect is caused, and a large number of templates and supports cannot be circulated.

Most construction sites at the present stage adopt a construction method of using a steel pipe shoring after demolishing, but the method causes a plurality of quality and safety accidents when a formwork and a gap between a support and the steel pipe shoring are demolished; the construction method of the later steel pipe jacking cannot ensure that the applied stress of the jacking just meets the structural requirements, so that quality accidents are caused; in some construction projects, a concrete column is additionally arranged in the same period as the structural concrete, and the post-cast strip is dismantled after construction is finished.
