Fabricated core-grouting wall body, construction method of fabricated core-grouting wall body and frame for preparing wall body

Abstract

The invention discloses a fabricated core-grouting wall body, a construction method of the fabricated core-grouting wall body and a frame for preparing the wall body. A longitudinal first cavity is formed in a prefabricated wallboard for grouting concrete at a construction site, and the problem that the construction difficulty of grouting to horizontal seams in the prior art is high is effectivelysolved; the tension intensity between inner and outer leaf wallboards is further effectively enhanced, risks of die expansion of the existing double-side composite wall and die shell shear wall are overcome, so the inner and outer leaf wallboards can be made thinner. A die shell is bounded and fixed in a steel cage in advance, the die shell is not disassembled after completing concrete sproutingbut left in a prefabricated part to form the first cavity, and the problems that the die shell cannot be stressed in the process of using during later periods in the prior art, and due to the fact that a building transforms in the process of using, and hidden cracks are produced between the die shell and internal post-grouting concrete shear wall can be effectively solved; and the die shell is bounded and fixed in the steel cage, the die shell can be stressed in the process of using during the later periods, and the intensity of the prefabricated wallboard is further improved.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to an assembled core-filling wall, a construction method thereof and a frame for preparing the wall. Background technique [0002] At present, prefabricated buildings have been widely used. However, the existing concrete prefabricated components have problems such as large volume and heavy weight. For example, the vertical reinforcement of prefabricated shear walls is connected by sleeve grouting, which is too expensive, difficult to construct, and difficult to inspect quality. Although the existing formwork shear walls are integrated with formwork and formed steel bars in the factory, the formwork is not stressed in the later use and is only used as a formwork during the construction process without exerting its maximum effect. Deformation during the process, the formwork and the internal post-cast concrete shear wall are prone to invisible cracks. The double-sided laminat...
