A method for constructing vertical construction joints of post-pouring belt

Abstract

The invention, which belongs to the technical field of construction, discloses a vertical construction joint construction method of a post-casting strip. The method comprises: a post-casting strip construction section is selected at each reserved horizontal reinforcing steel bar for pouring a horizontal concrete board and a pipe-jacking reinforcing steel bar is arranged at a selected template position, wherein the pipe-jacking reinforcing steel bar is intersected with the horizontal reinforcing steel bar vertically and is bound to the horizontal reinforcing steel bar; circular pipes intersected with each horizontal reinforcing steel bar vertically are arranged at the two sides of each horizontal reinforcing steel bar respectively, arc grooves are arranged at side walls, close to each horizontal reinforcing steel bar, of the circular pipes, and each horizontal reinforcing steel bar is clamped into the arc grooves formed in the vertical circular pipes at the two sides of the horizontal reinforcing steel bar; and a plurality of circular pipes are inserted into the space among the backs of the vertical circular pipes, the circular pipes are arranged closely, and the gaps among the horizontal reinforcing steel bars are filled, so that pipe templates are formed at the selected template positions. The vertical construction joint construction method is simple and is easy to implement;the labor and materials are saved; and the post-casting strip cleaning can meet the standard without extra efforts.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a method for constructing vertical construction joints of post-cast belts. Background technique [0002] For reinforced concrete projects whose plane exceeds a certain length and width, in order to weaken the cracks caused by concrete hydration shrinkage, deformation joints or post-casting strips are often set. Deformation joints, especially when used in basements, are often not favored due to ten joints and nine leaks, so more and more designs are turned to post-casting tapes. The post-pouring belt is usually 0.8m-1.5m wide, and the steel bars are reserved for disconnection. After about 60 days of concrete pouring on both sides, the reserved horizontal steel bars are connected and concrete is poured to form two vertical construction joints. When the post-pouring tape is used in underground engineering or roofing, in order to avoid water leakage in the construction joints, ...
