Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to a modular, box-type house. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods.

[0003] Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods.

[0004] However, in some prefabricated buildings, the connection points of each beam and column are usually connected by connectors during frame assembly. In existing technology, connectors need to connect beams and columns on multiple sides simultaneously, and the beams and columns are usually disconnected at the connection points, which makes the connection points prone to deformation, affecting the stability and service life of the building structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a modular, box-type house to solve the problem of easy deformation caused by the breakage of beams and columns at connection points in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model proposes a modular, box-type house, including an outer frame. The inner side of the outer frame has three mutually perpendicular inner frames: a first inner frame, a second inner frame, and a third inner frame. Each inner frame is connected to a beam. The outer frame is connected to a first rod via corner connectors. Each inner frame is connected to a corresponding rod via a corresponding inner frame connector. Each beam is connected to a rod in the adjacent inner frame via a beam end connector. The three beams are interconnected via a central connector. The inner frame connectors and beam end connectors are fitted onto the outside of the corresponding rod or beam, ensuring that the rod and beam remain continuous at the connection point.

[0007] Furthermore, the corner connector is the first connector, located at the octagon of the outer frame, and consists of three mutually perpendicular and fixed insertion pipes, used to connect the first rods in three directions.

[0008] Furthermore, the inner frame connector includes a sleeve portion and a plug portion, the sleeve portion being sleeved on the first rod body, and the plug portion being used to connect the rod body of the inner frame.

[0009] Furthermore, the inner frame connector includes a second connector for the first inner frame, a third connector for the second inner frame, and a fourth connector for the third inner frame.

[0010] Furthermore, the beam end connector includes two sleeve parts and one plug part. The two sleeve parts are respectively sleeved on the rods of two adjacent inner frames, and the plug part is used to connect the beam end.

[0011] Furthermore, the beam end connector includes a fifth connector for the first beam, a sixth connector for the second beam, and a seventh connector for the third beam.

[0012] Furthermore, the central connector includes three mutually perpendicular sleeves, which are respectively fitted onto the three beams.

[0013] Furthermore, all connectors are fixedly connected to the rods and beams using bolts.

[0014] Furthermore, the house also includes prefabricated wall panels, prefabricated floor panels, and prefabricated roof panels, which are filled in the skeleton formed by the outer frame, inner frame, and beams.

[0015] Furthermore, the spatial structure formed by the outer frame, inner frame, and beams is cubic in shape.

[0016] The beneficial effects of this utility model are as follows: The main skeleton of the house is formed by an outer frame, three mutually perpendicular inner frames, and corresponding beams, with various specialized connectors achieving a stable connection. Each connector is installed on the outside of the corresponding rod and beam using a sleeve-fitting method, ensuring that the rod and beam remain connected at the connector location, unlike traditional techniques where they are disconnected at the connection point. This design provides external support through the connectors, distributing localized stress across the entire rod or beam, effectively avoiding stress concentration at the connection point, and thus significantly improving the deformation resistance of the house structure. The house adopts a modular design, assembled from various standardized components connected by bolts, and filled internally and externally with precast wall panels, precast floor panels, and precast roof panels. This design allows the house to be completely disassembled before assembly, greatly facilitating transportation and factory production, while on-site assembly is simple and quick, conforming to the development trend of modern industrialized construction. The special structural design of each connector ensures assembly accuracy and connection strength, improving the overall performance of the house. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-11 The modular box-type house shown here is based on the fact that the core of it is to achieve the overall connection of the poles and beams through a modular connector system, which effectively avoids deformation at the connection points.

[0021] The modular, box-type house comprises an outer frame 1, three inner frames (first inner frame 2, second inner frame 3, and third inner frame 4), beams (first beam 5, second beam 6, and third beam 7), and various connectors. The outer frame 1, inner frames, and beams are arranged perpendicularly to each other, forming a cubic spatial skeleton. The components are assembled using a connector system, which is divided into four categories: corner connectors (i.e., first connector 8), inner frame connectors (including second connector 10, third connector 12, and fourth connector 14), beam end connectors (including fifth connector 16, sixth connector 17, and seventh connector 18), and center connectors (i.e., eighth connector 19). All connectors are fixed to the rods or beams with bolts, and the inner frame connectors and beam end connectors use a socket joint method to ensure that the rods and beams remain integrally connected at the connection points.

[0022] like Figure 3 As shown, the corner connectors (i.e., the first connectors 8) are located at the octagons of the outer frame 1 and consist of three mutually perpendicular and fixed first insertion pipes 20. Each first insertion pipe 20 is used to insert and fix the first rod 9, and the outer frame 1 is expanded and assembled in three directions by bolt connection.

[0023] The inner frame connectors include a second connector 10 for the first inner frame 2, a third connector 12 for the second inner frame 3, and a fourth connector 14 for the third inner frame 4. Each of these inner frame connectors includes a sleeve portion and a plug portion. The sleeve portion is fitted onto the first rod 9, and the plug portion is used to connect to the rod of its respective inner frame.

[0024] like Figure 4 As shown, the second connector 10 includes a first sleeve 21 and a second insertion sleeve 22. The first sleeve 21 is sleeved on the outside of the first rod 9, and the second insertion sleeve 22 is vertically fixed to the adjacent sides of the first sleeve 21 for connecting the second rod 11.

[0025] like Figure 5 As shown, the third connector 12 includes a third insertion tube 23, a fourth insertion tube 24, and a second set of tubes 25. The second set of tubes 25 is sleeved on the outside of the first rod 9, and the third insertion tube 23 and the fourth insertion tube 24 are vertically fixed for connecting the third rod 13.

[0026] like Figure 6 As shown, the fourth connector 14 includes a fifth connector 26, a sixth connector 27, and a third connector 28. The third connector 28 is fitted onto the first rod 9, and the fifth connector 26 and the sixth connector 27 are used to connect to the fourth rod 15.

[0027] The beam end connectors include a fifth connector 16 for the first beam 5, a sixth connector 17 for the second beam 6, and a seventh connector 18 for the third beam 7. Each of these beam end connectors includes two sleeve portions and one insertion portion. The sleeve portions are respectively sleeved on the rods of two adjacent inner frames, and the insertion portion is used to connect the ends of the beams.

[0028] like Figure 7 As shown, the fifth connector 16 includes a fourth connecting pipe 29, a fifth connecting pipe 30, and a seventh insert connecting pipe 31. The fourth connecting pipe 29 is fitted on the outside of the second rod 11, the fifth connecting pipe 30 is fitted on the outside of the third rod 13, and the seventh insert connecting pipe 31 is used to connect to the end of the first beam 5.

[0029] like Figure 8 As shown, the sixth connector 17 includes a sixth connecting pipe 32, a seventh connecting pipe 33, and an eighth insert connecting pipe 34. The sixth connecting pipe 32 is fitted onto the outside of the third rod 13, the seventh connecting pipe 33 is fitted onto the outside of the fourth rod 15, and the eighth insert connecting pipe 34 is used to connect to the end of the second beam 6.

[0030] like Figure 9 As shown, the seventh connector 18 includes an eighth connecting pipe 35, a ninth connecting pipe 36, and a ninth insert connecting pipe 37. The eighth connecting pipe 35 is fitted on the outside of the fourth rod 15, the ninth connecting pipe 36 is fitted on the outside of the second rod 11, and the ninth insert connecting pipe 37 is used to connect to the end of the third beam 7.

[0031] like Figure 10 As shown, the central connector (eighth connector 19) includes the tenth set of connecting pipes 38, the eleventh set of connecting pipes 39 and the twelfth set of connecting pipes 40. The three sets of connecting pipes are arranged perpendicularly to each other and are respectively fitted on the outside of the first beam 5, the second beam 6 and the third beam 7. They are fixed by bolts to achieve the central intersection connection of the three beams.

[0032] The assembly process of the modular house in this embodiment is as follows: Preparation stage: The inner frame connectors (second connector 10, third connector 12, fourth connector 14) are pre-fitted onto the corresponding first rod 9, but the bolts are not tightened yet, allowing the connectors to slide on the rod. The beam end connectors (fifth connector 16, sixth connector 17, seventh connector 18) are pre-fitted onto the corresponding inner frame rods (e.g., second rod 11, third rod 13, fourth rod 15), but the bolts are not tightened yet. The center connector (eighth connector 19) is pre-fitted onto the first beam 5, second beam 6, and third beam 7, but the bolts are not tightened yet.

[0033] During the assembly phase, the beams are installed first, followed by the simultaneous assembly of the inner frame members and the outer frame 1.

[0034] The beam assembly is as follows: The end of the first beam 5 is inserted into the seventh insertion pipe 31 of the fifth connector 16, and connected to the second rod 11 and the third rod 13 via the fourth and fifth insertion pipes 29 and 30. The end of the second beam 6 is inserted into the eighth insertion pipe 34 of the sixth connector 17, and connected to the third rod 13 and the fourth rod 15 via the sixth and seventh insertion pipes 32 and 33. The end of the third beam 7 is inserted into the ninth insertion pipe 37 of the seventh connector 18, and connected to the fourth rod 15 and the second rod 11 via the eighth and ninth insertion pipes 35 and 36. The central connector (eighth connector 19) is adjusted to the intersection of the three beams, but the bolts are not tightened yet. The inner frame rods are installed as follows: The second rod 11 is inserted into the second insertion pipe 22 of the second connector 10, connecting to the first inner frame 2. The third rod 13 is inserted into the third insertion pipe 23 and the fourth insertion pipe 24 of the third connector 12, connecting to the second inner frame 3. Insert the fourth rod 15 into the fifth insertion tube 26 and the sixth insertion tube 27 of the fourth connector 14 to connect the third inner frame 4. Do not tighten the bolts on any of the inner frame rods and connectors yet, maintaining flexibility at the connection points between the inner frame and the outer frame 1. Assemble the outer frame 1 by fixing the corner connectors (first connectors 8) to the octagonal positions of the outer frame 1. Insert the first rod 9, pre-installed with the inner frame connectors, into the first insertion tube 20 of the corner connectors, initially forming the outer frame 1 structure. At this time, all bolts remain loose to maintain the frame's flexibility and facilitate adjustment. When assembling the outer frame 1, a parallel, two-by-two alignment method can be used to avoid the last first rod 9 being unable to be assembled.

[0035] Adjust the position of all components to ensure that all connection points are aligned, and then tighten all bolts.

[0036] After the frame is assembled, precast wall panels, precast floor panels, and precast roof panels are installed and filled into the frame to form a complete house structure. The precast panels are connected to the frame via slots or bolts to ensure sealing and stability.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
