Description

Technical Field

[0001] The utility model relates to the technical field of modular buildings, in particular to a concrete building module. Background Art

[0002] Prefabricated buildings are buildings that are manufactured in factories, such as floor slabs, wall panels, stairs, balconies, etc., and then assembled and installed through connecting structures to form a building. Prefabricated buildings have many advantages such as controllable quality, high construction efficiency, and environmental friendliness. Among them, concrete building modules are favored by the majority of owners due to their superior performance in fire prevention, sound insulation, and heat insulation.

[0003] Existing concrete building modules mainly include one-piece molding and assembly type. Among them, the one-piece molding type uses a mold to form the building module as a whole at one time, such as a container-type building module. The assembly type building module first manufactures each component such as the wall, ceiling and floor separately, and then connects each component through bolts or pouring concrete to assemble it into an integral module.

[0004] However, the one-piece building module has low flexibility and cannot adapt to the needs of different scenarios. At the same time, the one-piece building module cannot be used universally between different building projects, that is, the mold cannot be used universally, resulting in high construction costs. In addition, the production and assembly process of assembled building modules is cumbersome and inefficient, which limits the application of prefabricated building modules. Utility Model Content

[0011] In one embodiment of the present application, an avoidance portion is provided at the bottom of the wall panel, and the avoidance portion is located below the connecting member, so that when a plurality of building modules are stacked, the connecting member on the wall panel located below can extend into the avoidance portion on the wall panel located above.

[0012] In one embodiment of the present application, a connecting hole is provided at the bottom of the avoidance portion; the connecting member can be passed through the connecting hole, so that when a plurality of building modules are stacked, the connecting member can be passed through the connecting hole and connected to a nut to fasten the two stacked building modules.

DETAILED DESCRIPTION

[0028] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0029] In the description of the present invention, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] The one-piece building module has low flexibility and cannot adapt to the needs of different scenarios. At the same time, the one-piece building module cannot be used universally between different building projects, that is, the mold cannot be used universally, resulting in high construction costs. In addition, the production steps of assembled building modules are cumbersome and inefficient during production and assembly, which limits the application of assembled building modules. Therefore, a concrete building module is proposed to solve the above problems.

[0032] The scheme is further illustrated by the following examples:

[0033] See also Figure 1 The concrete building module of this embodiment may include a perimeter wall 10, a cover plate 20 and a fastener 30. The perimeter wall 10 includes a plurality of wall panels 11, and the cover plate 20 may be connected to the top and bottom of the perimeter wall 10, i.e., connected to the wall panels 11, through the fastener 30 to form a box-type building module.

[0034] See also Figure 2 The wall 10 may include a plurality of wall panels 11. The plurality of wall panels 11 may be assembled into a wall of a specific shape to meet actual construction requirements and improve the versatility of the building module.

[0035] It should be noted that, in some other embodiments, the fence 10 may also be provided in an integrated manner, that is, the fence 10 may also be integrally formed at one time by pouring concrete in a mold.

[0036] Since the wall panels 11 can be manufactured separately, and the wall 10 can be assembled by selecting the wall panels 11 as needed, or the wall 10 can also be cast as a whole at one time according to actual needs, thereby improving the versatility of the building module.

[0037] In this embodiment, the wall 10 includes four wall panels 11, and the four wall panels 11 can be spliced ​​together to form the wall surface of the container-type building.

[0038] It should be noted that openings can be provided on the wall panel 11 according to actual needs so that structures such as doors and windows can be installed.

[0039] See also Figure 1 and Figure 3 The cover plate 20 can be connected to the top and bottom of the enclosure 10 to cover both ends of the enclosure 10, so that the cover plate 20 and the enclosure 10 can form a building module with internal accommodation control.

[0040] When the cover plate 20 is installed on the top of the wall panel 11 , the cover plate 20 can serve as a top plate of the building module, that is, a ceiling, to cover the top of the surrounding wall 10 .

[0041] When the cover plate 20 is installed at the bottom of the wall panel 11 , the cover plate 20 can serve as a bottom plate of the building module, that is, a floor, to be connected to the bottom of the surrounding wall 10 .

[0042] Of course, when multiple building modules are stacked, the cover plate 20 on the lower building module can serve as the top plate of the lower building module, and can also serve as the bottom plate of the upper building module at the same time, that is, two vertically connected building modules share a cover plate 20 to construct a building body.

[0043] See also Figure 3 The fastener 30 can be connected between the enclosure 10 and the cover plate 20 to fasten the cover plate 20 to the enclosure 10 .

[0044] In this embodiment, the fastener 30 can be configured as a bolt.

[0045] See also Figure 3 and Figure 4 The cover plate 20 may be provided with a through fixing hole 21. A plurality of fixing holes 21 are provided so as to be able to connect a plurality of wall panels 11 through fasteners 30.

[0046] See also Figure 2-4The top and bottom of the wallboard 11 may be provided with mounting holes 12. When the cover plate 20 is mounted on the wallboard 11, the mounting holes 12 can be aligned with and communicated with the fixing holes 21, so that the fasteners 30 can be inserted into the mounting holes 12 and the fixing holes 21.

[0047] The wall panel 11 may be provided with transverse keels 13 and connecting nuts 14 .

[0048] The length direction of the transverse keel 13 can extend in the horizontal direction. The transverse keel 13 is embedded in the concrete to improve the structural strength of the wall panel 11.

[0049] Two transverse keels 13 may be provided, and the two transverse keels 13 may be vertically spaced apart, so that the two transverse keels 13 can be located at the upper and lower sides of the wall panel 11 respectively.

[0050] More than two transverse keels 13 may be provided, and the plurality of transverse keels 13 may be vertically spaced apart to improve the structural strength of the wall panel 11 .

[0051] See also Figure 2 and Figure 3 The wall panel 11 may also be provided with a vertical keel 16. The length direction of the vertical keel 16 extends vertically and is connected to the transverse keel 13 to improve the overall structural strength of the wall panel 11.

[0052] A plurality of vertical keels 16 may be provided, and the plurality of vertical keels 16 are arranged at intervals in the transverse direction and connected to the transverse keels 13 to improve the structural strength of the mounting hole 12 .

[0053] See also Figure 3 , the connecting nut 14 can be fixed on the transverse keel 13.

[0054] Specifically, the connecting nut 14 is expected to be welded on the transverse keel 13 and embedded in the wall panel 11, thereby improving the connection strength between the connecting nut 14 and the fastener 30, and improving the connection strength between the transverse keel 13 and the wall panel 11, to avoid the fastener 30 and the wall panel 11 from becoming loose after the wall panel 11 is disassembled and assembled multiple times, thereby affecting the connection stability between the fastener 30 and the connecting nut 14.

[0055] The connecting nut 14 may be located in the mounting hole 12 , so that the fastener 30 can be inserted into the fixing hole 21 and the mounting hole 12 and connected to the connecting nut 14 , thereby fastening the cover plate 20 to the top and bottom of the wall panel 11 .

[0056] It should be noted that, since the connecting nut 14 is pre-buried in the wall panel 11 and welded to the transverse keel 13 in the wall panel 11, the connecting nut 14 can be firmly connected to the wall panel 11, thereby improving the connection stability between the fastener 30 and the wall panel 11. When the cover panel 20 is connected to the wall panel 11 through the fastener 30, the connection stability between the cover panel 20 and the surrounding wall 10 can be ensured, thereby improving the connection stability of the building module.

[0057] At the same time, since the connecting nut 14 is located in the mounting hole 12, the fastener 30 is directly connected to the connecting nut 14 after passing through the mounting hole 12, thereby avoiding drilling during on-site construction and improving on-site installation efficiency.

[0058] In addition, since the fixing hole 21 is pre-set, drilling is avoided at the construction site. At the same time, the fixing hole 21 can be adapted to the mounting hole 12. When the cover plate 20 is overlapped on the wall plate 11, the fixing hole 21 and the mounting hole 12 can be connected and coaxially arranged, thereby facilitating the fastener 30 to pass through the fixing hole 21 and the mounting hole 12, and fasten the cover plate 20 to the wall plate 11.

[0059] Specifically, after the cover plate 20 is overlapped onto the fence 10, the fastener 30 is connected to the fixing hole 21 and the mounting hole 12, and bolted with the connecting nut 14, that is, the bolts are tightened between the cover plate 20 and the wall panel 11, thereby improving the installation efficiency between the fence 10 and the cover plate 20.

[0060] See also Figure 3 A sleeve 22 may be disposed in the fixing hole 21 . The sleeve 22 is coaxially disposed with the fixing hole 21 to resist against the fastener 30 .

[0061] Specifically, the sleeve 22 can be a metal sleeve. The sleeve 22 is preset in the fixing hole 21 to improve the connection strength between the cover plate 20 and the fastener 30, thereby improving the stability of the cover plate 20 connected to the wall plate 11 through the fastener 30.

[0062] See also Figure 3 A lap groove 23 may be provided at the bottom of the cover plate 20 .

[0063] Specifically, the overlap groove 23 is recessed toward one side of the cover plate 20 so that the overlap groove 23 can overlap the top of the wall plate 11. When the cover plate 20 is overlapped on the top or bottom of the wall plate 11 through the overlap groove 23, waterproof glue is applied between the wall plate 11 and the cover plate 20 to improve the waterproof effect of the entire building structure. That is, the overlap groove 23 can be used to accommodate the waterproof glue to improve the sealing of the connection between the cover plate 20 and the wall plate 11, and the waterproof effect of the connection between the cover plate 20 and the wall plate 11.

[0064] See also Figure 2 and Figure 3 , the cover plate 20 may be provided with a positioning hole 24, and the wall plate 11 may be provided with a connector 15. One end of the connector 15 may be pre-buried in the wall plate 11, and the other end of the connector 15 vertically protrudes from the top of the wall plate 11 so as to be inserted into the positioning hole 24. When the cover plate 20 is overlapped on the wall plate 11, the connector 15 and the positioning hole 24 may be positioned to increase the accuracy of the overlap of the cover plate 20 on the wall plate 11.

[0065] The connecting member 15 can be connected to the transverse keel 13 , thereby improving the connection strength between the connecting member 15 and the wall panel 11 .

[0066] It should be noted that the end of the connecting member 15 protruding from the top of the wall panel 11 can penetrate the positioning hole 24 and protrude the positioning hole 24 upward to be connected to the building module overlapped above, so as to improve the connection strength between the two building modules when they are stacked, thereby improving the connection stability between the modular building bodies.

[0067] See also Figure 2 and 4 A relief portion 25 may be provided at the bottom of the wall panel 11 .

[0068] The avoidance portion 25 is located below the connector 15, so that when multiple building modules are stacked, the connector 15 on the lower wall panel 11 can extend into the avoidance portion 25 on the upper wall panel 11, so as to facilitate workers to tighten connectors such as nuts on the end of the connector 15, thereby facilitating the overlap and connection of the two building modules.

[0069] See also Figure 5 and Figure 6 A connecting hole 26 may be provided at the bottom of the avoidance portion 25 .

[0070] The connection hole 26 can be used to pass the connection piece 15, so that when a plurality of building modules are stacked, the connection piece 15 can pass through the connection hole 26 and be connected with a nut to fasten the two stacked building modules.

[0071] See also Figure 5 and Figure 6 The concrete building module may further include a base plate 40 .

[0072] The bottom plate 40 can be connected to the bottom of the enclosure 10. Specifically, the bottom of the bottom plate 40 is flush with the bottom of the enclosure 10.

[0073] The bottom plate 40 can be connected to the inner wall of the enclosure 10 by connecting bolts, thereby facilitating the connection between the bottom plate 40 and the enclosure 10 and improving the connection efficiency between the enclosure 10 and the bottom plate 40 .

[0074] A plurality of bottom plates 40 may be provided, and the plurality of bottom plates 40 are arranged in parallel at the bottom of the enclosure 10 .

[0075] It should be noted that the base plate 40 can be used as the floor of the building module.

[0076] See also Figure 7 The bottom of the cover plate 20 may be provided with a plurality of recessed portions 27, and the plurality of recessed portions 27 are distributed in the horizontal direction. It should be noted that the recessed portions 27 are provided on the cover plate 20, and the overall weight of the cover plate 20 can be reduced while ensuring the overall structural strength of the cover plate 20, thereby facilitating the transportation and hoisting of the cover plate 20.

[0077] It should be noted that the enclosure 10 and the cover plate 20 can be mass-produced in a factory through a mold, and then transported to a construction site for assembly. The enclosure 10 can be formed as a whole at one time, and then spliced ​​with the cover plate 20 to assemble into a building module. At the same time, the wall panels 11 can be first manufactured using a mold, and then the wall panels 11 are spliced ​​into the enclosure 10, and the enclosure 10 is spliced ​​with the cover plate 20 to assemble into a building module.

[0078] In summary, the enclosure 10 can be formed by splicing or casting multiple wall panels 11 at one time, and the cover plate 20 can be connected to the enclosure 10 through the fasteners 30 to form a building module. The wall panel 11 is provided with a transverse keel 13, and the connecting nut 14 is connected to the transverse keel 13 and is located in the mounting hole 12. The fastener 30 is inserted into the fixing hole 21 and connected to the nut 14, so that the connection strength between the cover plate 20 and the enclosure 10 can be improved, and the connection between the cover plate 20 and the enclosure 10 is convenient, and the splicing efficiency between the cover plate 20 and the enclosure 10 is improved.

[0079] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
