A kind of prefabricated toilet and its construction and installation method

Abstract

The invention discloses a prefabricated toilet and a construction and installation method thereof. The prefabricated toilet includes a bottom plate unit, four wall surface units and a ceiling plate unit which are mutually and fixedly connected; the bottom plate unit, the wall surface units and the ceiling plate unit are constructed by reinforced concrete; doors and windows are arranged on the wall surface units; at least one wall surface unit or a part of one wall surface unit of the four wall surface units is of a semi-prefabricated structural wall, the thickness of the semi-prefabricated structural wall is less than the whole thickness of a building structural wall, a plurality of raised columns are arranged on an outer side surface of the semi-prefabricated structural wall in the normal direction thereof, the height of the raised columns plus the thickness of the semi-prefabricated structural wall equals the whole thickness of the building structural wall, top surfaces of the plurality of raised columns are parallel to the outer side surface of the semi-prefabricated structural wall, and bolts for accurately positioning and installing cast-in-situ wall templates are arranged on the top surface of each raised columns. The prefabricated toilet is easy to construct and install, is firm and stable in structure, and can greatly improve the efficiency of on-site construction.

Description

technical field [0001] The invention relates to buildings, in particular to a prefabricated toilet and its construction and installation method. The invention can be widely applied to various high-rise buildings. Background technique [0002] Toilets are an indispensable part of residential buildings. At present, the following two methods are generally used to build toilets: one is to directly cast a concrete frame on the construction site and build toilets one by one. This is the most traditional and commonly used toilet construction method. The traditional toilet construction method has a long construction period and high construction cost, and the quality standard of the toilet cannot be well guaranteed due to the non-standard use of building materials. The second is to prefabricate the complete toilet in the factory, and then transport it to the construction site for installation.

AI Technical Summary

Problems solved by technology

[0006] 2) When the upper outer formwork is arranged outside the frames of the four wall units and the ceiling unit, the lower half of the outer formwork is difficult to install flat, and it is easy to cause joint seams in this part of the wall unit. In addition, after installing the outer formwork, It is necessary to keep the second fixed steel mold vertical by adjusting the lever, but the verticality of the outer mold is difficult to adjust, and there is often a phenomenon of inclination

Difficult to install and disassemble due to the large number of mold parts; Poor integrity and shock resistance, prone to seams

[0008] In addition, the existing prefabricated bathroom installation methods also have certain defects: when the existing prefabricated bathroom installs cast-in-place panels on the outside of the semi-prefabricated structural wall, in order to achieve the set structural wall thickness, multiple positioning adjustments are required. difficult to adjust

In addition, when installing cast-in-place panels on the outside of the semi-prefabricated structural walls of traditional prefabricated toilets, the alignment and installation are carried out through the pre-embedded nuts in the semi-prefabricated structural walls, which is easy to cause less installation and concealment.
