Description

Technical Field

[0001] This invention belongs to the field of construction, specifically relating to a prefabricated steel structure house structure. Background Technology

[0002] Modular steel structure housing, as a new type of prefabricated housing, is gradually becoming an important development direction in the housing industry due to its advantages of high degree of prefabrication, short construction cycle, and flexible spatial layout. Its core construction logic is to disassemble the overall housing structure into several independent minimum functional units, complete the prefabrication in the factory, transport them to the housing construction site for splicing and assembly, and finally form a complete housing structure.

[0003] However, existing modular steel structure housing design and construction methods still present irreconcilable technical contradictions. In the unit breakdown stage, the size of the smallest unit faces a dilemma: setting the smallest unit to a larger size reduces the variety of units and the complexity of on-site assembly, but the transportation of ultra-large units is extremely difficult due to limitations in transportation channels, equipment capacity, and access restrictions, making conventional transportation impossible; conversely, excessively reducing the size of the smallest unit to meet transportation needs leads to a significant increase in the variety of minimum units required for the house, increasing not only the prefabrication process and management costs in the factory but also posing significant challenges to on-site assembly.

[0004] In addition, steel structure materials are inherently heavy, requiring precise selection and matching of different types and specifications of the smallest units during on-site assembly. An excessive number of unit types can easily lead to material confusion, misassembly, and omissions, increasing assembly costs. Summary of the Invention

[0005] The prefabricated steel structure housing structure provided by this invention can effectively solve the problems existing in the background art.

[0006] This invention provides a prefabricated steel structure house structure, comprising:

[0007] The first mating element is rod-shaped, with a first mating connector and a second mating connector at each end; the side of the second mating connector is provided with a fourth mating groove that is adapted to the first mating connector.

[0008] And the second docking element, which is L-shaped, with a first docking groove and a second docking groove at each of the two ends that are adapted to the first docking connector and the second docking connector respectively, and a third docking groove that can be adapted to the second docking connector on each of the four faces of the corner end.

[0009] The first docking element serves as an edge, and the second docking element serves as a point. Twelve first docking elements and eight second docking elements can be assembled into a cube.

[0010] As a further optimization of the present invention, the first mating element is a pipe with a square cross-section; the first and second joints are squares with slightly smaller side lengths and concentric with the cross-section of the first mating element, and the side length of the cross-section of the first joint is smaller than that of the cross-section of the second joint.

[0011] As a further optimization of the present invention, the fourth mating groove is provided on each of the four sides of the second connector.

[0012] As a further optimization of the present invention, the lengths of both the first and second joints are equal to the side length of the cross section of the first mating element.

[0013] As a further optimization of the invention, a cap is also included for sealing the gap formed after the first pair of connectors is inserted into the third mating groove.

[0014] As a further optimization of the present invention, the cap includes:

[0015] The insertion part is tubular and adapts to the gap formed between the first pair of connectors and the third mating groove after the first pair of connectors is inserted into the third mating groove.

[0016] And a sealing plate, which covers one end of the plug-in portion and has an area larger than the end face of the plug-in portion.

[0017] As a further optimization of the present invention, the first docking element is used as an edge, the second docking element is used as a point, and several first docking elements and second docking elements are spliced ​​together to form a cuboid structure stacked longitudinally or laterally; the cover is provided with four.

[0018] As a further optimization of the invention, the second joints of the four first mating elements that serve as vertical edges in the cube face downwards.

[0019] As a further optimization of the present invention, both the first docking element and the second docking element are made of steel or aluminum alloy.

[0020] As a further optimization of the present invention, the outer wall of the second docking element having the first docking groove is provided with a "<" shaped mark with the tip facing the groove opening, and the outer wall of the second docking groove having the opening facing the groove opening is provided with a "<" shaped mark.

[0021] This invention employs standardized docking elements and structures, enabling the assembly of cubic and cuboid structures using only one type of rod-shaped first docking element and one type of L-shaped second docking element. It features simple, efficient, and highly adaptable assembly, effectively avoiding the problem of confusion in the smallest unit of traditional modular steel structure housing assembly. Multiple optimized designs are incorporated during construction to enhance structural stability and ease of assembly, making it suitable for rapid construction scenarios of various prefabricated steel structure houses.

Detailed Implementation

[0031] Example 1

[0032] like Figure 1-5 As shown, this embodiment includes a first docking element 1 and a second docking element 2.

[0033] The first docking element 1, serving as the "side" component of the assembly, is a rod-shaped structure, preferably made of a square-section pipe. It has a first connector 1a and a second connector 1b at each end. Both connectors 1a and 1b are square structures concentric with the cross-section of the first docking element 1, with slightly smaller side lengths. The side length of the first connector 1a is smaller than that of the second connector 1b, while the lengths of both connectors 1a and 1b are equal to the side length of the first docking element 1, ensuring precision and fit during docking.

[0034] In other embodiments, the first docking element 1 may also be a solid rod or a circular cross-section tube.

[0035] In this embodiment, the fourth mating groove 1b1 is provided on each of the four sides of the second mating joint 1b. The mating groove is adapted to the first mating joint 1a and can realize quick docking with other components.

[0036] The second docking element 2 serves as a "point" component in the assembly and has an overall L-shaped structure. Its two ends are respectively provided with a first docking groove 2a and a second docking groove 2b. The first docking groove 2a and the second docking groove 2b are adapted to the first mating connector 1a and the second mating connector 1b of the first docking element 1, so as to achieve precise snap-fit ​​with the first docking element 1.

[0037] The corner end of the second docking element 2 has a third docking groove 2c on each of the four sides. The third docking groove 2c can dock with the second joint 1b of the first docking element 1, which is the core structure for realizing multi-directional splicing.

[0038] The first docking groove 2a and the second docking groove 2b of the second docking element 2 have different groove sizes. To improve assembly convenience, the side walls of the corresponding docking grooves of the second docking element 2 are marked with different markings. The outer side wall of the first docking groove 2a is marked with a "<" shaped mark 2d with the tip pointing towards the groove opening, and the outer side wall of the second docking groove 2b is marked with a "<" shaped mark 2d with the opening pointing towards the groove opening. This makes it easy for construction personnel to quickly identify the large and small openings and improve assembly efficiency.

[0039] After the assembly is completed, the tips of all the “<” shaped marks 2d point to the second mating joint 1b. The two mating joints of the second mating element 2 can be identified at any time through the mark 2d.

[0040] In this embodiment, twelve first docking elements 1 and eight second docking elements 2 are assembled into a cube. The specific assembly rules are as follows:

[0041] With the first docking element 1 as an edge and the second docking element 2 as a point, the eight second docking elements 2 are respectively used as the eight vertices of the cube. The second docking element 2 at each vertex is connected to the end of the adjacent first docking element 1 through the first docking groove 2a and the second docking groove 2b to form the basic frame of the cube.

[0042] The four first mating elements 1 that serve as vertical edges in the cube must have their second mating joints 1b facing downwards to ensure the stability of the vertical edge structure.

[0043] Furthermore, in this embodiment, all the first docking elements 1 and the second docking elements 2 are preferably made of steel. This type of material has the characteristics of high strength, corrosion resistance, and easy processing, which can effectively ensure the load-bearing capacity and service life of steel structure houses, while also meeting the needs of prefabricated rapid assembly and reducing construction difficulty. In other embodiments, the first docking elements 1 and the second docking elements 2 may also be made of aluminum alloy.

[0044] It should be noted that this embodiment is applied to temporarily constructed houses with relatively small overall load-bearing capacity. If necessary, columns can be added for reinforcement after the cube is constructed.

[0045] This embodiment enables rapid frame assembly, effectively avoiding the component confusion issues of traditional modular houses. After the frame is assembled, subsequent reinforcement and wall sealing operations are simpler, significantly improving the overall assembly speed.

[0046] Example 2

[0047] like Figure 6 , 7 As shown, this embodiment is based on the cube splicing logic of embodiment 1, and a cuboid structure can be built by vertically stacking. The specific method is as follows:

[0048] Similar to Example 1, the basic cube structure is first completed using the first docking element 1 as an edge and the second docking element 2 as a point, following the cube construction method.

[0049] According to actual needs, along the longitudinal direction of the cube, the second docking element 2 connects with the second joint 1b of the adjacent first docking element 1 through the third docking groove 2c, and the cube is continuously stacked and spliced ​​to gradually expand into a cuboid structure.

[0050] This embodiment only stacks two layers vertically; in other embodiments, three, four, or even more layers can be stacked.

[0051] One point needs to be noted: In embodiment 1, the first mating joints 1a of the four first mating elements 1, which are vertical ridges, all face upward and mate with the third mating groove 2c of the second mating element 2. However, the size of the third mating groove 2c is not completely adapted to the first mating joints 1a, and there is a wall thickness of the second mating joint 1b in between, which will cause slight loosening between the two.

[0052] However, during the upward stacking process, only the first mating joint 1a of the first mating element 1, which is the topmost vertical ridge, is mated with the third mating groove 2c of the second mating element 2, which is the topmost vertical ridge. The third mating grooves 2c of the second mating element 2 in the middle are all filled by the second mating joint 1b of the first mating element 1, which is the middle vertical ridge.

[0053] Therefore, the higher the number of layers, the less likely there is a loose connection, and the smaller the impact of that loose connection on the whole.

[0054] Furthermore, this embodiment adds a cap 3 to completely solve the problem of loose connection at this location.

[0055] The cap 3 is used to seal the gap formed between the first joint 1a and the third mating groove 2c after the first joint 1a is inserted into the third mating groove 2c.

[0056] Specifically, the cover 3 includes a tubular insertion part 3a and a sealing plate part 3b. The size of the insertion part 3a is adapted to the gap formed after the first mating connector 1a is inserted into the third mating groove 2c, so that it can be tightly inserted into the gap. The sealing plate part 3b blocks the end face of the insertion part 3a. The area of ​​the sealing plate part 3b is larger than the end face area of ​​the insertion part 3a, which not only seals the gap, but also facilitates assembly and disassembly.

[0057] The cap 3 can improve the sealing and stability of the spliced ​​structure.

[0058] The cap 3 in this embodiment is also applicable to embodiment 1.

[0059] Example 3

[0060] like Figure 8 As shown, this embodiment is basically the same as embodiment 2, except that this embodiment adopts a horizontally stacked structure.

[0061] The difference between this embodiment and embodiment 1 is that this embodiment does not require all the second joints 1b of the first docking element 1 that serve as vertical ridges to face downwards. Therefore, in this embodiment, the second joints 1b of the first docking element 1 that serve as vertical ridges can face upwards or downwards. Regardless of the orientation or the number of stacked layers, only four caps 3 are required.

[0062] The principle is that in the cuboid structure, the second mating element 2 that connects the four sides does not need to be capped 3. There are a total of eight points connecting the three sides, of which four points must be connected to the second mating joint 1b of the first mating element 1. Therefore, only four caps 3 are needed.

[0063] It should be understood that the descriptions of directions or positional relationships such as up, down, left, right, front, back, top, bottom, tail, horizontal and vertical in this application are all based on the accompanying drawings in the specification and are only used to express the technical solution more clearly and simplify the description, rather than indicating or implying that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this application.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
