Technical Field
The utility model relates to a temporarily seal prefabricated device in basement outer wall post-cast strip relates to the house and builds engineering basement construction field.
Background
The design specification of the existing concrete structure makes clear requirements, and the maximum distance between expansion joints of the concrete structure is strictly designed and calculated. This requires the designer to carefully handle the adverse effects on the structure due to the overlength in the design of the structure. When the space between the expansion joints of the structure is increased or the expansion joints are not designed, practical measures must be taken to prevent the structure from cracking. Among measures for properly increasing the maximum distance of the expansion joint, an anti-cracking measure is adopted in the structural construction stage, and the method is an effective method for reducing adverse effects of concrete shrinkage at home and abroad. The common practice in China is to set a post-construction casting strip. When the structure has a large height difference but the structural design can not be provided with a permanent deformation joint, a structural post-cast strip is also often used to solve the problem of uneven settlement. The multi-storey and high-rise building construction project designed with the basement or other construction projects with underground projects are all provided with post-settlement casting belts so as to solve the problem of structural difference settlement in the construction stage.
In the construction of the basement outer wall post-cast strip structure, the concrete post-cast time of the post-cast strip is not uniform due to design and structure differences, but most of the post-cast strip is closed by post-casting 42 days after concrete of structures on two sides of the post-cast strip is cast. According to the traditional process, after the required time for concrete sealing reaches the design requirement, chiseling and cleaning, erecting a template, pouring concrete, removing the template, curing, waterproof construction and backfilling are carried out, so that the construction period is long, the backfilling of earthwork can not generate great influence on a construction site and a construction road, and the construction operation of outdoor engineering is also influenced.
