Advanced closing structure of basement roof post-pouring strip and construction method

Abstract

The invention provides an advanced closed structure of a basement roof post-pouring strip. A profiled steel sheet is used for covering the roof post-pouring strip; a cover plate steel bar covers the upper side of the profiled steel sheet and concrete is casted in situ on the upper side to form a cast-in-situ concrete cover plate layer; a steel tube extends to the position between the two sides of the basement roof; and a coil waterproof layer covers the cast-in-situ concrete cover plate layer and the outer side of the side wall of the steel tube. The invention further provides a construction method for realizing the advanced closure of the basement roof post-pouring strip by using the closed structure. The construction method includes the steps that a basement roof formwork bent is erected; the advanced closed structure of the basement roof post-pouring strip is erected; a formwork bent system of the roof formwork bent post-pouring strip part is erected; concrete is poured on the roof post-pouring strip through the steel tube and vibrating is carried out; and the formwork bent system of the roof formwork bent post-pouring strip part and the profiled steel support are removed, and construction is completed. The roof post-pouring strip is temporarily sealed first, and after a greening landscape body is completed, the roof post-pouring strip is poured by taking the reserved steel tube as a pouring concrete discharge conduit.

Description

technical field [0001] The invention relates to an early sealing structure of a post-casting tape on a basement roof. [0002] The invention relates to a construction method for an early sealing structure of a post-casting belt on a basement roof.

[0003] During the construction, before the main structure of the building is completed, before the post-pouring tape around the high-rise building is blocked and poured, earth backfilling and greening landscape construction are carried out on the basement roof in advance to create a construction area environment. In order to ensure that the greening landscape is in the first construction situation The safety of the basement roof structure and the pouring quality of the post-cast belt in the later stage, the existing technology usually closes the construction of the basement roof post-cast belt in advance, but the existing technology has the following disadvantages: the design of the closed cover plate structure at the top of the post-cast belt is unreasonable, The construction is difficult, which may cause potential safety hazards in the future; the waterproof design of the post-casting belt on the roof is flawed, which may easily cause water seepage in the building in the future
