Description
Technical Field
The invention relates to the technical field of building construction, in particular to a structure and a die for pre-closing a post-pouring zone of a basement and a construction method.
Background
The post-cast strip is a concrete strip which is reserved in the structures such as a foundation slab, a wall, a beam and the like, has a certain width and is cast after a certain time in order to adapt to the influence of factors such as environmental temperature change, concrete shrinkage, uneven settlement of the structure and the like. The traditional basement outer wall post-cast strip needs to be poured after the main body structure is completed and sedimentation is stable, construction progress of basement outer wall backfill is severely restricted, the post-cast strip needs to be sealed in advance for shortening construction period, and meanwhile leakage of a later outer wall is effectively avoided.
In the traditional construction method for closing the basement post-cast strip in advance, the construction quality of the bottom plate or the raft post-cast strip outside the outer wall which is connected with the basement outer wall post-cast strip cannot be ensured on site. In order to ensure that the pouring of the part is compact, the site is often forced to pour in advance, and the design requirement is violated. If pouring is not performed in advance, after the external wall is backfilled, pouring can only be performed from the inner side of the basement in the process of closing the bottom plate or the raft at the later stage, and the pouring compactness of the local bottom plate or the raft post-pouring belt cannot be ensured.
In the traditional construction method for closing the basement post-cast strip in advance, the basement outer wall post-cast strip is usually closed in advance in the form of bricked guard walls (most commonly used), finished concrete precast slabs, steel plates and the like on site. The construction method of the brick-built enclosure wall has the advantages of complex working procedures, high construction cost, low structural rigidity of the enclosure wall, and difficult waterproof construction, and the joint part of the enclosure wall and the outer wall forms a 90-degree internal angle, so that the waterproof quality is difficult to ensure; the construction method of the finished concrete precast slab has high cost of raw materials, the construction needs to be hoisted by large equipment, supporting and reinforcing measures are needed to be set temporarily after the installation is completed, the side edge of the precast slab is generally 100mm thick, and the joint part of the precast slab and the outer wall forms a 90-degree internal angle, so that the waterproof construction difficulty is high, and the waterproof quality is difficult to ensure; the steel plate sealing construction method has high raw material cost and the leakage prevention level is the lowest in the construction process.
