Cement prefabricated part and method applied to internal space construction of high-rise building

Abstract

The invention discloses a cement prefabricated part and method applied to internal space construction of a high-rise building. The cement prefabricated part comprises a prefabricated part assembly, a heat preservation and sound absorption plate, a first connecting assembly, a fixing block, a connecting column, a limiting groove, a first spring, a first limiting block, a first clamping block, a second connecting assembly, a sleeve, a groove, a clamping groove, a slurry hanging assembly, a limiting box, a second limiting block, a connecting plate, a slurry hanging groove, a partition plate and a second spring. According to the cement prefabricated part, a heat-insulation and sound-insulation material is used as a pre-buried part. The pre-buried part is directly fixed to the cement prefabricated part through the pouring procedure, it can be ensured that connection is firmer, meanwhile, follow-up construction is reduced, and therefore cost is reduced, and construction efficiency is improved. The connecting assemblies are designed and can be used for auxiliary positioning when the cement prefabricated parts are spliced, and meanwhile the connecting strength between the prefabricated parts is improved; the slurry hanging assembly is designed, and a slurry hanging position can be provided for cement slurry in the follow-up seam filling procedure, so that the seam filling difficulty is reduced, and the seam filling quality is improved.

Description

technical field [0001] The invention relates to the technical field of cement prefabricated parts, in particular to a cement prefabricated part and a method for building interior spaces of high-rise buildings. Background technique [0002] When constructing the interior space of a building, prefabricated interior wall panels are required. Compared with traditional masonry walls, prefabricated interior wall panels have good advantages. First, they can be plaster-free and reduce hollowing, cracking, etc. Common problems, the second is that the construction speed is fast, less restricted by climatic conditions, saving labor and improving construction quality; [0003] Most of the existing prefabricated interior walls adopt a hollow structure in order to achieve thermal insulation and sound insulation effects, and then fill the cavity with thermal insulation and sound insulation materials. It is a solid connection, which greatly weakens the sound insulation effect. If thermal i...

Problems solved by technology

[0003] Most of the existing prefabricated interior walls adopt a hollow structure in order to achieve thermal insulation and sound insulation effects, and then fill the cavity with thermal insulation and sound insulation materials. It is a solid connection, which greatly weakens the sound insulation effect. If thermal insulation and sound insulation materials are installed on the wall, the sound insulation effect can be effectively achieved, and the temperature difference between the air and the wall can be reduced to avoid condensation on the wall. However, this method Secondary construction is required, which increases the cost, and the insulation and sound insulation materials must be completely attached to the foundation wall without leaving any gaps, otherwise water may still hang between the wall and the insulation board and mold will occur, which further increases the construction cost. difficulty;

[0004] The existing prefabricated interior wall panels are completely positioned, calibrated and installed by manpower. The error coefficient is large, and the construction quality cannot be guaranteed. In addition, manual positioning will lead to large gaps between the wall panels, which will affect the subsequent grouting and repairing process, and are prone to voids and cracks. False seams affect the quality of the wall;

[0005] Existing prefabricated interior walls lack auxiliary joint filling structures, especially when grouting the top joints, if the gaps are large, it is difficult to hang grout, and the quality of joint filling is difficult to be guaranteed
