Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more particularly to a load-bearing structure for buildings. Background Technology

[0002] In existing metal building structures, the internal connections between load-bearing slabs are typically secured with bolts. This method involves creating through holes at adjacent connection points and using bolts for fastening to achieve assembly and force transmission between the slabs. However, this single connection method relies primarily on the shearing action between the bolt shank and the hole wall or end-face compression to transfer loads. Its effective load-bearing area in the vertical direction (i.e., perpendicular to the slab surface) is relatively small, leading to stress concentration, hole wall deformation, and even bolt loosening or breakage at connection nodes under large vertical loads. Summary of the Invention

[0003] The present invention provides a load-bearing structure for houses to overcome the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A load-bearing structure for a house includes an elliptical cylindrical key and a house load-bearing plate; the house load-bearing plate includes a front plate and a rear plate; the upper end of the surface of the front plate and the rear plate along the width direction is provided with a plurality of first key holes; the lower end of the surface of the front plate and the rear plate along the width direction is provided with a plurality of second key holes; the elliptical cylindrical key is respectively embedded in the first key holes and the second key holes to connect the front plate and the rear plate.

[0005] Furthermore, the major axis of the elliptical cross-section of the elliptical cylindrical key is arranged in the horizontal direction, with the end of the major axis forming a horizontal working end and the end of the minor axis forming a vertical working end.

[0006] Furthermore, limiting plates are provided at both the upper and lower ends of the front and rear plate surfaces along the width direction.

[0007] Furthermore, connecting through holes are provided on both sides of any one of the keyholes.

[0008] Furthermore, the limiting plate includes a first limiting plate and a second limiting plate; the upper ends of the front plate and the rear plate are respectively provided with the first limiting plate, and the lower ends are respectively provided with the second limiting plate, and the connecting through hole passes through the front plate, the rear plate and the limiting plate respectively.

[0009] Furthermore, the connecting through hole includes an upper connecting through hole provided on the first limiting plate and a lower connecting through hole provided on the second limiting plate. A first fixing bolt is provided in the upper connecting through hole, and a second fixing bolt is provided in the lower connecting through hole. The first fixing bolt passes through and connects the first limiting plate, the front plate, and the rear plate, and the second fixing bolt passes through and connects the second limiting plate, the front plate, and the rear plate, so as to fix the front plate and the rear plate to the first limiting plate and the second limiting plate respectively into a house load-bearing plate structure.

[0010] Furthermore, a gap is pre-set between the front plate and the rear plate for the insertion of the upper floor slab.

[0011] Furthermore, the width of the limiting plate is greater than the width of the elliptical cylindrical key.

[0012] Furthermore, the four load-bearing slabs of the house enclose a rectangular base plate structure, and the rectangular base plate structure is provided with house structural components at its two diagonal positions and at the horizontal and vertical axes of symmetry.

[0013] Beneficial Effects: This invention significantly improves the overall load-bearing capacity and stress performance of a load-bearing structure by embedding elliptical cylindrical keys in the load-bearing slab of a building. Specifically, after the elliptical cylindrical keys are embedded in pre-set keyholes, they can provide a larger effective bearing area under vertical loads, effectively dispersing local stress and avoiding stress concentration or connection failure problems caused by the small bearing area in traditional single bolt connections. Simultaneously, the geometry of the elliptical cylindrical keys helps to limit the relative displacement of the load-bearing slab in both horizontal and vertical directions, enhancing node stiffness and overall structural stability. Furthermore, this structure can efficiently strengthen existing metal building load-bearing systems without significantly increasing material usage or complex assembly processes, offering advantages such as simple construction, convenient installation, and high reliability.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This embodiment provides a load-bearing structure for a house, such as... Figure 1 As shown, the structure includes an elliptical cylindrical key 1 and a load-bearing plate 2. The elliptical cylindrical key 1 is embedded in a pre-set keyhole 3 in the load-bearing plate 2 to enhance its load-bearing capacity. Specifically, as... Figures 1 to 4As shown, the load-bearing plate 2 of the building includes a front plate 201 and a rear plate 202 arranged opposite to each other. The upper ends of the surfaces of the front plate 201 and the rear plate 202 along the width direction are respectively provided with a plurality of first keyholes 301, and the lower ends of the surfaces along the width direction are respectively provided with a plurality of second keyholes 302. Elliptical cylindrical keys 1 are respectively embedded in the aligned first keyholes 301 and second keyholes 302, thereby reliably connecting the front plate 201 and the rear plate 202 at their upper and lower ends, forming a stable load-bearing unit. After the elliptical cylindrical keys 1 are embedded in the preset keyholes, they can provide a larger effective bearing area under vertical loads, effectively dispersing local stress and avoiding the stress concentration or connection failure problems caused by the small bearing area in traditional single bolt and nut connections. Calculations show that the load-bearing capacity of a single elliptical cylindrical key 1 structure in the vertical direction can reach four times that of a single bolt and nut connection structure. At the same time, the geometry of the elliptical cylindrical key 1 helps to limit the relative displacement of the load-bearing plate in the horizontal and vertical directions, enhancing the node stiffness and overall structural stability. Furthermore, this structure can efficiently strengthen the existing metal house load-bearing system without significantly increasing the amount of materials or complex assembly processes. It has the advantages of simple construction, convenient construction, and high reliability, and is particularly suitable for prefabricated house structures with high requirements for load-bearing performance and safety.

[0018] Furthermore, such as Figure 2 As shown, the elliptical cylindrical key 1 has an elliptical cross-section, with its major axis arranged horizontally. Thus, the protruding areas formed at both ends of the major axis of the elliptical cross-section constitute horizontal working ends 102, used to transmit shear force or limit the horizontal relative displacement between adjacent load-bearing plates in the horizontal direction; while the areas formed at both ends of the minor axis constitute vertical working ends 101, used to bear and transmit vertical loads, increasing the effective bearing area of ​​the load-bearing plate in the vertical direction. This arrangement fully utilizes the geometric characteristics of the elliptical cross-section, enabling the elliptical cylindrical key, after being embedded in the keyhole 3 of the load-bearing plate 2, to simultaneously and collaboratively bear horizontal and vertical loads, significantly improving the load-bearing capacity of the node connection and the overall structural integrity.

[0019] Furthermore, such as Figures 1 to 4 As shown, limiting plates 4 are provided at the upper and lower ends of the front plate 201 and rear plate 202 along the width direction to limit the displacement of the elliptical cylindrical key 1 in the front-rear direction, preventing it from coming off or loosening during stress. Through the cooperation between the keyhole 3 and the elliptical cylindrical key 1, combined with the constraint effect of the limiting plates, this structure not only effectively transmits vertical and horizontal loads, but also significantly improves the overall stiffness and connection reliability of the node.

[0020] Furthermore, such as Figure 4As shown, a first limiting plate 401 is provided at the upper end of the front plate 201 and the rear plate 202, and a second limiting plate 402 is provided at the lower end of the rear plate 202. The upper end of the front plate 201 and the rear plate 202 are provided with a plurality of first keyholes 301, and the lower end is provided with a plurality of second keyholes 302. Connecting through holes 5 are provided on both sides of each keyhole 3. In this embodiment, the front plate 201 and the rear plate 202 are also provided with connecting ports 6 for connecting to external building structural components.

[0021] Furthermore, such as Figures 1 to 4 As shown, the connecting through hole 5 includes an upper connecting through hole 501 on the first limiting plate 401 and a lower connecting through hole 502 on the second limiting plate 402, and the connecting through hole 5 penetrates the front plate 201, the rear plate 202 and the corresponding limiting plate 4. A first fixing bolt is installed in the upper connecting through hole 501, which passes through and is fastened to the first limiting plate 401, the front plate 201 and the rear plate 202 by a nut; a second fixing bolt is installed in the lower connecting through hole 502, which passes through and is fastened to the second limiting plate 402, the front plate 201 and the rear plate 202 by a nut. Through the above bolt and nut connection, the front plate 201, the rear plate 202 and the front and rear limiting plates 4 are fixed together as a whole. At the same time, the elliptical cylindrical key 1 is embedded in the aligned first key hole 301 and second key hole 302, and works in conjunction with the bolt and nut connection to jointly bear the vertical and horizontal loads, and the limiting plate 4 restricts the displacement of the elliptical cylindrical key 1 in the front-rear direction. In this embodiment, the width of the limiting plate 4 is preferably greater than the width of the elliptical cylindrical key 1, which can effectively cover and constrain the outer contour of the elliptical cylindrical key 1 in the front-back direction, thereby further improving the stability of the connection node.

[0022] like Figure 1 As shown in Figure 5, in an embodiment of the present invention, a gap is reserved between the front plate 201 and the rear plate 202 for inserting the upper floor slab, facilitating rapid assembly and load transfer between upper and lower floors. The four load-bearing slabs 2 are connected end-to-end to form a rectangular base plate structure. Structural components are provided along the two diagonals, the horizontal axis of symmetry, and the vertical axis of symmetry of this rectangular base plate structure to enhance the overall load-bearing capacity.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
