Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] This embodiment discloses a method for laying post-cast strips, which is especially suitable for laying post-cast strips of basement foundation beams, but not limited to post-cast strips of basement foundation beams.

[0033] The method aims to solve the technical problem that the existing post-casting belt part, especially the post-casting belt part of the foundation beam of the basement easily leaks into the concrete and is difficult to clean up.

[0034] combine figure 1 and 2 Describe in detail for this embodiment:

[0035] The method mainly involves that the raw material is a foam board 1, and the post-casting belt formwork 4 is a quick-and-easy closing net or a steel wire net.

[0036] When binding the steel bars 5 of the foundation beam 2 in the basement, the foam board 1 is cut as required, and when the steel bars 5 are bound, the foam board...

Abstract

The invention discloses a post-cast strip remaining method. The method comprises the following steps: (1) a foam plate is cut and used for fully filling a post-cast strip part to be remained; (2) when the post-cast strip part needs to be cast in the later period, the foam plate is smashed by using a tool; (3) water is injected in the post-cast strip part; the fragments of the foam plate are upwards floated; and then, the fragments of the foam plate are cleaned; and (4) the water accumulated in the post-cast strip part is removed. The post-cast strip remaining method overcomes the technical problem of difficult cleaning of concrete and impurities easily leaked in the post-cast strip part, in particular the post-cast strip part of a basement foundation beam during remaining of a post-cast strip in the prior art.

Description

technical field [0001] The invention relates to the technical field of building construction, more specifically, it relates to a post-casting tape retention method. Background technique [0002] In modern architectural design, a large number of ultra-long basement structures, super-large complexes and between the main building and podium of high-rise buildings, in order to reduce the concrete shrinkage stress and the uneven settlement design between the main structures, usually adopt the form of post-cast strips as a cast-in-place whole Temporary deformation joints left in reinforced concrete structures. [0003] After the post-casting belt is left, the formwork needs to be supported when the steel bars are bound, and then the concrete on both sides of the post-casting belt is poured, and the post-casting belt is poured after the concrete on both sides of the post-casting belt reaches the predetermined strength. However, in the prior art, no matter whether the steel wire me...
