Description

Technical Field

[0001] The utility model relates to the technical field of house structures, in particular to a modular house. Background Art

[0002] Develop intelligent construction, promote green building materials, prefabricated buildings and steel-structured houses, and build low-carbon cities. MiC (Modular Integrated Construction), also known as modular houses, has a high degree of integration and prefabrication rate. It can give full play to the advantages of industrialized, intelligent, integrated and standardized design and construction of buildings. It is an important innovative practice in the construction field to implement the "dual carbon" goals. In recent years, all parts of the world have been actively promoting the use of MiC technology in housing construction projects to improve the productivity and construction efficiency of the construction industry and speed up the solution to the problem of "grassroots housing". At present, most concrete modular houses use an integrated mold production process, which has the following problems and development obstacles:

[0003] (1) The commonly used production process at present is to cast the bottom plate first, and then cast the wall and top plate in one piece. The characteristics of this process are that it is produced in one piece, and the integrity of the module is strong. However, the thickness of the wall of the concrete modular house is generally 90-100mm. When pouring concrete, there is a quality risk that the concrete at the root of the wall is not vibrated densely, and it is easy to have problems such as honeycombs, rough surfaces, and holes.

[0004] (2) Most of the integrated molds are made of steel molds, which have the characteristics of high strength and can be reused many times. However, the steel mold is heavy. In order to facilitate disassembly and assembly, the amount of three-dimensional steel molds required for the production of concrete modular houses is large, and the mold cost rises sharply.

[0005] (3) The integrated production method uses a three-dimensional "inner liner" mold, which is difficult to dismantle and there is a risk of damaging the component during the demolding process.

[0006] (4) Concrete modular houses are heavy and have thin walls. During the hoisting process, due to problems such as the angle of the hoisting wire rope and the accuracy of the embedded hanging nails, the wall at the hanging nails is prone to stress concentration and damage, leading to safety accidents.

[0041] Such as Figure 1 and Figure 2 、 Figure 3As shown in the figure, a modular house in an embodiment of the present utility model includes a bottom plate 1 and precast wall panels 2; the bottom plate 1 includes a plate body 11 and a connecting ring beam 12 surrounding the plate body 11 on all sides, and the connecting ring beam 12 is provided with protruding stirrups 13; the precast wall panel 2 is reserved with lapping steel bars 21 adapted to the protruding stirrups 13; after the precast wall panel 2 is placed on the plate frame stirrups 31 of the plate body 11, the lapping steel bars 21 are lapped with the protruding stirrups 13. Specifically, the plate body 11 and the connecting ring beam 12 are connected by a steel bar lapping structure 3; the steel bar lapping structure 3 includes plate frame stirrups 31 arranged in the plate body and ring beam longitudinal bars 32 tied to the plate frame stirrups 31, and the ring beam longitudinal bars 32 are arranged inside the protruding stirrups 13; a 45° chamfer structure is adopted at the connection between the connecting ring beam 12 and the precast wall panel 2.

[0042] In the above modular house, by arranging a connecting ring beam 12 around the plate body 11, the self-weight, decoration and other loads are borne, and the tension during hoisting is borne to increase the overall stability of the modular house; at the same time, protruding stirrups 13 are reserved at the connection between the precast wall panel 2 and the bottom plate 1. After the precast wall panel 2 is installed in place, ring beam longitudinal bars 32 are placed inside the protruding stirrups 13 and the plate frame stirrups 31 are tied. A 45° chamfer is adopted at the connection between the connecting ring beam 12 and the plate body 11, and then concrete is cast in a second time, which can strengthen the connection between the bottom plate 1 and the precast wall panel 2 and improve the integrity of the modular house.

The surface of the lapping area is treated with roughness. The precast wall panel 2 is reserved with side extension steel bars 22 and top extension steel bars 23 for lapping, and then the steel bars are tied and the joints are cast.

[0044] In one embodiment, the support plate 4 includes vertical steel bars 41 lapped with the protruding stirrups 13. In this way, after the precast wall panel 2 is placed on the bottom plate 1, the vertical steel bars 41 are tied in the reserved space between the precast wall panels 2 to strengthen the connection structure between the precast wall panels 2.
