Basement outer wall post-cast strip structure and construction method

Abstract

The invention relates to the technical field of basement post-cast strips, in particular to a basement outer wall post-cast strip structure. The structure comprises an outer wall; a post-cast strip isarranged on the outer wall; a reinforcing mesh is exposed on the post-cast strip; the reinforcing mesh comprises transverse shafts and longitudinal shafts which are mutually staggered; a plurality oflongitudinally-arranged steel plates are arranged at the outer side of the post-cast strip; the steel plates shield the post-cast strip; upper shafts and lower shafts are fixedly connected with the faces, close to the reinforcing mesh, of the steel plates; when the steel plates are installed, the upper shafts and the lower shafts are located on the upper sides and the lower sides of the transverse shafts respectively, blocking parts penetrate through the ends, away from the steel plates, of the upper shafts and the lower shafts; and nuts are in threaded connection with the tail ends of the upper shafts and the lower shafts. The basement outer wall post-cast strip structure has the effect of improving the friendliness of the mounting environment of the steel plates.

Description

technical field [0001] The present application relates to the technical field of post-cast strips in basements, in particular to a structure and construction method of post-cast strips on exterior walls of basements. Background technique [0002] The post-pouring belt is a temporary construction joint at the corresponding position of the foundation floor, wall or beam in order to prevent the harmful cracks that may occur in the poured reinforced concrete structure due to uneven temperature and shrinkage during construction. The structure is temporarily divided into several parts. After the internal shrinkage of the components for a certain period of time, the construction joint concrete is poured and tamped to connect the structure into a whole. [0003] The traditional post-casting technology includes masonry work well protection method, post-casting tape advanced water-stop method and precast concrete masonry method, and there are many problems in the construction process....

AI Technical Summary

Problems solved by technology

Using the masonry working well protection method, when the outer wall is high, the working well is deep, the later construction is difficult, there are safety hazards, and it is easy to accumulate water, produce cracks, and collapse after backfilling; The construction process is complicated, it is difficult to formwork, reinforce and dismantle the protruding parts, and the cost of labor and materials is large; the precast concrete masonry method is adopted, the weight of the prefabricated block is large, and it needs to be processed on site, the process is complicated, and the protection of the finished prefabricated block is difficult, etc.

[0004] In the related technology, an advanced waterproof construction technology of steel plates attached to the post-casting belt of the basement exterior wall is proposed. The steel plate is used to replace the traditional post-casting belt to build the working well and prefabricated blocks. The construction is convenient, and the steel plate and the post-casting belt are welded and connected After the steel plate is installed, the waterproof layer and protective layer can be constructed, which can be constructed at the same time as the outer wall, and the earthwork can be backfilled at the same time, which achieves the effect of advanced waterproofing, and avoids some disadvantages of the post-pouring belt, and solves the waste of traditional technology. Difficulties in manpower, material resources, long construction period and difficult construction

[0005] In view of the related technologies mentioned above, the inventor believes that when the steel plates are installed layer by layer, it is necessary to weld multiple points between the steel plates and the distribution ribs of the post-casting tape, so that the steel plates can be installed stably, but the smoke and harmful gases generated by welding are not It is beneficial to the health of construction workers and causes pollution to the environment
