Description

TECHNICAL FIELD

[0001] The present application relates to a pre-poured floor slab roof post-pouring belt of an ultra-long building, in particular to a sealing formwork structure of two sides of a pre-poured floor slab roof post-pouring belt of an ultra-long building, and a construction method of the pre-poured floor slab roof post-pouring belt of the ultra-long building. BACKGROUND

[0002] In the construction of cast-in-place concrete of the floor top plate of a long-span building, a post-pouring belt is needed to be set on the floor top plate, the floor top plate on both sides of the post-pouring belt is poured first, and then the floor top plate at the post-pouring belt is poured again after the expansion and settlement of the poured concrete on both sides of the post-pouring belt are stable; when pouring the concrete of the floor top plate on both sides of the post-pouring belt, the post-pouring belt area needs to be isolated to prevent the concrete poured on both sides of the post-pouring belt from flowing into the post-pouring belt area, so that the post-pouring belt can fully play the role of absorbing the prestress of the concrete floor plate on both sides; according to the existing construction specification, the steel mesh in the floor top plate is integrally constructed, that is, the steel mesh on the post-pouring belt and the steel mesh on both sides of the post-pouring belt are integrally constructed at the same time, and these steel meshes are supported on the top surface of the floor top plate pouring formwork through concrete stool blocks to ensure that the steel mesh in the floor top plate can form a protective layer after the pouring of the floor top plate is completed, and the thickness of the protective layer of the steel mesh at the bottom of the floor top plate is generally between 2.5-3 cm; the pouring construction process of the floor top plate on site is as follows: after the steel mesh on the floor top plate is bound, the position of the post-pouring belt is determined, then the blocking formwork on both sides of the post-pouring belt is constructed, the blocking formwork includes a dense mesh wire netting, a wood glue strip and a truncated concrete batten, the dense mesh wire netting for blocking the cast-in-place concrete is arranged between the upper and lower steel mesh on both sides of the post-pouring belt, since the lower end of the dense mesh wire netting cannot be inserted into the lower steel mesh, the gap between the lower steel mesh and the floor top plate pouring formwork is blocked, the gap directly below the dense mesh wire netting is generally blocked by the wood glue strip on site, and the truncated concrete batten is arranged on the upper steel mesh directly above the dense mesh wire netting, so that the complete blocking formwork system for the cast-in-place concrete on one side of the post-pouring belt is constructed; after the expansion and settlement of the floor top plate on both sides of the post-pouring belt are completed, the floor top plate concrete pouring formwork is removed, at this time, the blocking wood glue strip is tightly combined with the poured concrete on both sides of the post-pouring belt, since the wood glue strip is prone to rot, according to the relevant specification, when the post-pouring belt concrete is poured again, the blocking wood glue strip must be removed from the once-poured and finally-cured concrete, then the concrete pouring formwork of the post-pouring belt is erected, and the secondary concrete pouring work of the post-pouring belt is carried out, so as to ensure the close combination of the twice-poured concrete; in actual operation, the removal of the blocking wood glue strip is time-consuming and laborious, and the phenomenon of incomplete removal of the blocking wood glue strip often occurs, which seriously affects the combination quality of the post-pouring belt concrete and the poured floor top plate concrete, and how to solve this problem is a difficult problem that needs to be solved in the construction site.
