Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a pre-enclosed post-cast strip structure of a basement top slab. Background Art

[0002] In order to prevent harmful cracks that may be caused by uneven temperature and shrinkage in cast-in-place reinforced concrete structures during construction, temporary construction joints are left in the corresponding positions of the foundation slab, wall, and beam in accordance with design or construction specifications. The structure is temporarily divided into several parts. After the internal shrinkage of the components, concrete is poured in the construction joints after a certain period of time to connect the structure into a whole. However, in order not to affect subsequent construction operations, the post-cast joints need to be sealed. The existing sealing method is to seal them with a cover plate.

[0003] The patent document with the published announcement number CN217352620U provides a prefabricated cover plate for pre-sealing the post-cast strip of the basement roof settlement. When in use, the first bolt is screwed into the first threaded hole in the cover plate, the sealing gasket and the cast-in-place plate to fix the cover plate, and then cement mortar is filled in the inner corner between the cover plate and the cast-in-place plate to increase the sealing performance. The top plate is covered on the cast-in-place plate so that the support rod is inside the movable hole. The sealing performance is improved by the tightening effect of the support rod and the sealing gasket. However, since the prefabricated cover plate cannot be adjusted, the post-cast strips of different thicknesses cannot be sealed. Utility Model Content
