[0002] According to 3.4.13 of the Technical Code for Concrete Structures of High-Rise Buildings JGJ3-2010, the concrete of the post-casting strip should be poured after 45 days; 5.2.2 of the Technical Code for Waterproofing of Underground Engineering GB50108-2008 stipulates that the post-casting strip should be constructed after the concrete age on both sides reaches 42 days; the construction of the post-casting strip of high-rise buildings should be carried out according to the prescribed time. Therefore, during the construction of the main structure, the post-casting strip needs to be reserved first and poured in batches, which requires blocking on both sides of the post-casting strip and taking separation measures on the side of the post-casting strip beam.
[0003] According to previous construction experience, the interception measures for the post-cast joints of the basement top slab beams are usually to use wire mesh tied to the beam stirrups at the junction of concrete of different strength grades in the post-cast joints of the beams to intercept and separate the concrete of different strength grades in the post-cast joints of the beams. Often the interception parts are not reinforced in place, resulting in serious phenomena such as honeycombs, rough surfaces, leakage, and misalignment. Utility Model Content
