Description

Technical Field

[0001] The utility model relates to the field of house construction, in particular to a modular low-rise house. Background Art

[0002] The traditional house construction process takes a lot of time, manpower and material resources, and often damages the environment, so people have been looking for more efficient and environmentally friendly construction methods. In recent years, with the continuous development of modular house technology, more and more countries have begun to promote the use of modular houses. At present, the development of modular houses is an effective measure to achieve energy conservation and environmental protection, improve the quality of buildings, and achieve the upgrading of the construction industry. Modular houses are a change in the construction method of traditional cast-in-place houses. Compared with traditional cast-in-place houses, modular houses produce components in factories, transport them to the site, and assemble them. The construction method of "building houses with building blocks" replaces the traditional method of pouring concrete to build houses. Since modular houses have only a few on-site concrete pouring operations, they have the advantages of environmental protection and energy saving.

[0003] In the market, the mainstream modular houses are mainly modular concrete houses and steel structure modular houses. For modular concrete houses, modular concrete shear wall structures and modular concrete frame structures are the main ones.

[0004] The modular concrete frame structure has many components with multiple reinforcements, complex on-site construction procedures, and large concrete column cross-sections. Not only are the columns exposed indoors, but the pipeline layout is also complicated, which limits the application of this system.

[0005] The prefabricated shear walls of modular concrete shear wall structures require sleeve grouting connections and grout-anchor lap steel bar connections. The sleeves are expensive, complicated to operate, difficult to control construction quality, and slow to build. The grout-anchor lap steel bar connections use pre-reserved hole grouting operations, which require delicate operations and are difficult to control quality, and are not the optimal construction method.

[0006] The load-bearing components of steel structure modular houses are all made of steel structure, which has relatively poor comfort, and the price of steel is relatively high. It is greatly affected by market fluctuations. Due to the characteristics of steel, its application in single-story and small-span houses is limited. Utility Model Content

[0079] At least two lifting rings 8 are pre-embedded at the top of the wall panel 1 and the corner column 4. In this embodiment, four lifting rings 8 are pre-embedded at the top of the wall panel 1 and the corner column 4. Fig.13 , Fig.24 and Fig.25 The roof panel 2 is provided with a vertical through hole 9 which matches with the hanging ring 8. Figures 17 to 20 The outside of the hanging ring 8 is buried in the through hole 9 of the roof panel 2 through the post-cast concrete 7b, so as to realize the fixed connection between the roof panel 2 and the wall panel 1 and the corner column 4 respectively.

[0080] The lifting ring 8 has two functions: first, it is used to lift the wall panel 1 and the corner column 4 during installation; second, the lifting ring 8 is anchored in the through hole 9 of the roof panel 2 through the post-cast concrete 7b of the hole portion, thereby strengthening the connection between the roof panel 2 and the wall panel 1 and the corner column 4. In order to ensure the anchoring strength of the lifting ring 8, the embedded length of the lifting ring 8 in the wall panel 1 and the corner column 4 is 20 cm to 40 cm.

[0081] The wall panel 1 includes an end wall panel 11 and a middle wall panel 12. In this embodiment, the end wall panel 11 and the middle wall panel 12 have the same size. One end of the end wall panel 11 is connected to the corner column 4, and the other end of the end wall panel 11 is connected to one end of the middle wall panel 12 or to one end of another end wall panel 11.

[0086] The wall panels 1 and the roof panels 2 are lightweight panels, which are easy to transport and install. The low-rise modular low-rise house refers to a house with a height of no more than three wall panels 1, and the wall panels 1 can withstand the force of the house. Specifically, the wall panel 1 includes at least one substrate board 15 filled inside and a toughening layer 16 added on the surface of the substrate board 15, such as Fig.16 As shown.

A vertical seam is formed between the basic beam 3 and the corner base 10, and the vertical seam is filled with post-cast concrete 7e between the beams to achieve the connection and fixation between the basic beam 3 and the corner base 10.

[0089] Embodiment 3:

[0090] The difference from the first embodiment is that: one end of the wall panel 1 is provided with a plate tenon 14, and the other end of the wall panel 1 is provided with a plate trapezoidal groove 13 that matches the plate tenon 14. Fig.37 As shown, the end wall panel 11 and the middle wall panel 12 have the same size; the end surface of the corner column 4 is provided with a column tenon 42 that matches the plate trapezoidal groove 13, and the other end surface of the corner column 4 is provided with a column trapezoidal groove 41 that matches the plate tenon 14, as shown in FIG. Fig.39 The connection between adjacent wall panels 1 and between the wall panels 1 and the corner columns 4 is a tenon-and-groove connection. Fig.38 and Fig.40 The vertical joints between adjacent wall panels 1 and between the wall panels 1 and the corner columns 4 no longer rely on traditional mortar bonding but rely on the socket engagement between the tenons and the trapezoidal grooves to provide shear resistance, and cracking is not easy to occur at the vertical joints. During assembly, the plate trapezoidal grooves 13 and the column trapezoidal grooves 41 are filled with waterproof glue, and the plate tenons 14 and the plate trapezoidal grooves 13, the plate tenons 14 and the column trapezoidal grooves 41, and the plate trapezoidal grooves 13 and the column tenons 42 are butted together to achieve good waterproofing effects.

[0091] Embodiment 4:

[0092] The difference from the third embodiment is that: a plate tenon 14 is provided at one end of the wall panel 1, and a plate triangular groove 17 matching with the plate tenon 14 is provided at the other end of the wall panel 1. Fig.41 and Fig.42 The end surface of the corner column 4 is provided with a column tenon 42 that matches the plate triangular groove 17. The other end surface of the corner column 4 is provided with a column triangular groove 43 that matches the plate tenon 14, as shown in FIG.

The connection state of the end wall panel 11 and the middle wall panel 12 is as shown in FIG. Fig.43 As shown, the connection state between the end wall panel 11 and the corner column 4 is as shown in FIG. Fig.45 The vertical joints between adjacent wall panels 1 and between the wall panels 1 and the corner columns 4 are filled with post-cast concrete 7d between the wall panels, which strengthens the connection between adjacent wall panels 1 and between the wall panels and the corner columns 4, and improves the structural stability.

[0093] Embodiment 5:

[0094] The difference from the first embodiment is that the left and right sides of the roof panel 2 are both flat. Figure 46 to Figure 49 The left and right end faces of adjacent roof panels 2 are connected to reduce the workload of on-site construction.

[0095] The wall panels 1 and roof panels 2 of the modular low-rise house can be combined into a complete building structure as needed, thereby achieving fast, flexible and economical house construction. The wall panels 1 and roof panels 2 can be added or deleted as needed, and the foundation beams 3 can be prepared in different lengths to suit different family needs and lifestyles. In addition, the modular low-rise house is also built faster because each wall panel 1, roof panel 2 and foundation beam 3 can be produced in different places and assembled together on site. This can greatly reduce construction costs, improve the affordability of the house, and also have good comfort and safety.
