Description

Technical Field

[0001] This utility model relates to the field of keel reinforcement structure technology, specifically to a deformation-resistant composite frame metal keel reinforcement structure. Background Technology

[0002] In the field of architectural decoration and structural construction, the stability of metal keel frames is the core of ensuring the overall quality of the project—especially in scenarios such as large suspended ceilings and lightweight partition walls that rely on keel load-bearing, keel deformation may cause surface cracking or even overall collapse.

[0003] The traditional metal keel reinforcement method used on construction sites mostly relies on welding or bolting of single steel sections, which can basically meet the load-bearing requirements of small-span structures, but it has shortcomings in large-span or complex stress conditions: the connection nodes between the main keel and the side keel are prone to loosening, and the frame as a whole is prone to bending or twisting after long-term stress. When encountering vibration loads, it may also generate resonance amplification deformation, resulting in cracks in the surface material.

[0004] To enhance resistance to deformation, common improvements include increasing the thickness of the keel wall or adding simple reinforcements. However, this leads to new dilemmas: either excessive thickening results in material waste and increased installation load, or the reinforcement layout is unreasonable, causing stress to concentrate at the connection points and local deformation to become more severe. Especially when temperature changes cause thermal expansion and contraction, the rigid connection reinforcement structure is more likely to generate internal stress, accelerating aging and cracking.

[0005] This approach cannot guarantee the long-term stability of the structure and will increase unnecessary material consumption and construction difficulty. To address these issues, a deformation-resistant composite frame metal keel reinforcement structure is proposed. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a deformation-resistant composite frame metal keel reinforcement structure, which solves the problem that traditional metal keel reinforcement methods mostly rely on welding or bolting of single steel sections.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant composite frame metal keel reinforcement structure, comprising two main keels and two side keels. The two main keels are arranged vertically and vertically, and the two side keels are arranged front-to-back. The two side keels are located on opposite sides of the two main keels. The two main keels are both H-beams. The two side keels are concave in shape. Two second reinforcing plates are welded to the opposite sides of the two main keels. The ends of the four second reinforcing plates away from the main keels are inclined and fixedly connected to the corresponding side keels.

[0008] Preferably, each of the two side keels is provided with a third reinforcing plate on its opposite surface. The two third reinforcing plates are arranged in a front-to-back correspondence, and the upper and lower surfaces of the two third reinforcing plates are respectively fixedly connected to the corresponding second reinforcing plates.

[0009] Preferably, each of the two main keels has a first reinforcing plate on its opposite surface, and the two first reinforcing plates are arranged vertically and vertically.

[0010] Preferably, the left and right ends of the two first reinforcing plates are respectively fixedly connected to the corresponding second reinforcing plates.

[0011] Preferably, the inner walls of both main keels are fixedly connected with multiple V-shaped reinforcing ribs, and the multiple V-shaped reinforcing ribs are interconnected.

[0012] Preferably, each of the two side keels has four first mounting holes.

[0016] Preferably, the outer walls of the eight fixing bolts are threaded with fixing nuts, thereby fixing the two side keels to the opposite surfaces of the two first reinforcing plates.

[0017] (III) Beneficial Effects Compared with the prior art, this utility model provides a deformation-resistant composite frame metal keel reinforcement structure, which has the following beneficial effects: 1. This anti-deformation composite frame metal keel reinforcement structure, through the inclined support of the second reinforcing plate, the lateral reinforcement of the first reinforcing plate, the vertical reinforcement of the third reinforcing plate, the local reinforcement of the V-shaped reinforcing ribs, and the firm connection of the fixing bolts, the various components work together to form a multi-layered, all-round reinforcement system, so that when the composite frame metal keel is subjected to longitudinal, lateral or torsional forces, it can effectively disperse stress, reduce deformation, and improve the stability and deformation resistance of the overall structure.

[0018] 2. In this anti-deformation composite frame metal keel reinforcement structure, the second reinforcing plate (in an inclined position) located at the connection between the main keel and the side keel begins to play its role: the inclined second reinforcing plate transmits and disperses the longitudinal force borne by the main keel and the lateral force borne by the side keel, forming a triangular stable structure (the main keel, the side keel and the second reinforcing plate form a triangle). The stability of the triangle enhances the overall shear resistance of the frame and reduces the frame torsional deformation caused by external forces (such as pressure and tension).

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a new technical solution: a deformation-resistant composite frame metal keel reinforcement structure, including two main keels 1 and two side keels 6. The two main keels 1 are arranged vertically and vertically, and the two side keels 6 are arranged front-to-back. The two side keels 6 are located on opposite sides of the two main keels 1. The two main keels 1 are both H-steels. The two side keels 6 are concave in shape. Two second reinforcing plates 4 are welded to the opposite sides of the two main keels 1. The ends of the four second reinforcing plates 4 away from the main keels 1 are inclined and fixedly connected to the corresponding side keels 6.

[0023] Furthermore, a third reinforcing plate 5 is provided on the opposite surfaces of the two side keels 6. The two third reinforcing plates 5 are arranged in a front-to-back correspondence, and the upper and lower surfaces of the two third reinforcing plates 5 are respectively fixedly connected to the corresponding second reinforcing plates 4.

[0024] Furthermore, each of the two main keels 1 has a first reinforcing plate 3 on its opposite side, and the two first reinforcing plates 3 are arranged vertically and vertically.

[0025] Furthermore, the left and right ends of the two first reinforcing plates 3 are respectively fixedly connected to the corresponding second reinforcing plates 4.

[0026] Furthermore, multiple V-shaped reinforcing ribs 2 are fixedly connected to the inner walls of both main keels 1, and the multiple V-shaped reinforcing ribs 2 are interconnected.

[0027] Furthermore, each of the two side keels 6 has four first mounting holes 7.

[0028] Furthermore, each of the two main keels 1 has four second mounting holes 8.

[0029] Furthermore, the eight second mounting holes 8 correspond to the eight first mounting holes 7 respectively.

[0030] Furthermore, corresponding to the second mounting hole 8, fixing bolts are inserted into the inner wall of the first mounting hole 7.

[0031] Furthermore, the outer walls of the eight fixing bolts are all threaded with fixing nuts, thereby fixing the two side keels 6 to the opposite surfaces of the two first reinforcing plates 3.

[0032] Furthermore, when using this anti-deformation composite frame metal keel reinforcement structure, the two side keels 6 and the two third reinforcing plates 5 are first assembled; First, place one of the main keels 1 below, take out two side keels 6, place the two side keels 6 on the upper surface of the main keel 1, and align the two first mounting holes 7 below them with the second mounting holes 8 on the main keel 1, and then fix them with fixing bolts. Then, another main keel 1 is taken out and placed on top of the two side keels 6, so that the four second mounting holes 8 on it correspond to the first mounting holes 7 on the two side keels 6, and then it is fixed by the connecting fixing bolts. This completes the installation of the two side keels 6 and the two third reinforcing plates 5, which together form a rectangle. Then, the two third reinforcing plates 5, the four second reinforcing plates 4, and the two first reinforcing plates 3 are welded to the designated positions. Among them, the second reinforcing plate 4 (in an inclined position) located at the connection position of the main keel 1 and the side keel 6 begins to play its role: the inclined second reinforcing plate 4 transmits and disperses the longitudinal force borne by the main keel 1 and the lateral force borne by the side keel 6, forming a triangular stable structure (the main keel 1, the side keel 6 and the second reinforcing plate 4 form a triangle). The stability of the triangle enhances the overall shear resistance of the frame and reduces the frame torsional deformation caused by external forces (such as pressure and tension). Among them, the third reinforcing plate 5, which is set at the front and rear respectively, connects the two side keels 6 and is fixed with the upper and lower second reinforcing plates 4, thereby enhancing the compressive strength of the two upper and lower corresponding second reinforcing plates 4. The first reinforcing plate 3, which is set at the top and bottom respectively, connects to the second reinforcing plate 4 on the left and right sides to form a horizontal support structure, which enhances the overall integrity of the frame in the vertical direction, prevents the connection node between the main keel 1 and the side keel 6 from breaking due to excessive local stress, and at the same time helps to disperse the force transmitted by the second reinforcing plate 4, reducing the load on individual nodes. Among them, multiple V-shaped reinforcing ribs 2 on the inner wall of the main keel 1 are interconnected. The V-shaped structure itself has good compressive and bending resistance, which can effectively enhance the connection strength between the web and flange of the H-steel main keel 1, prevent the main keel 1 from being locally dented or bent due to stress, and the multiple V-shaped reinforcing ribs are interconnected to form a mesh support, further improving the rigidity of the main keel. Among them, the fixing bolts and fixing nuts firmly connect the side keel 6 and the main keel 1 through the first mounting hole 7 and the second mounting hole 8, so as to avoid the connection loosening due to vibration or stress during long-term use of the frame, and ensure that the force transmission between each reinforcing plate and the keel is stable and reliable. Among them, through the inclined support of the second reinforcing plate 4, the lateral reinforcement of the first reinforcing plate 3, the vertical reinforcement of the third reinforcing plate, the local reinforcement of the V-shaped reinforcing rib 2, and the firm connection of the fixing bolts, the components work together to form a multi-level, all-round reinforcement system, so that when the composite frame metal keel is subjected to longitudinal, lateral or torsional forces, it can effectively disperse stress, reduce deformation, and improve the stability and deformation resistance of the overall structure.

[0033] Structural Description: Main Keel 1: It is made of H-beams, with corresponding upper and lower parts, and a second reinforcing plate 4 welded to the opposite side. The inner wall is connected with V-shaped reinforcing ribs 2, and a second mounting hole 8 is opened. It is the longitudinal main support structure of the composite frame, which bears the main longitudinal force. The overall resistance to deformation is improved by strengthening the components.

[0034] Side keel 6: It is concave in shape and is set in a corresponding manner at the front and back. It is located on the opposite side of the two main keels 1, with the first mounting hole 7. It is fixed to the main keel 1 by bolts. It is the lateral support structure of the frame, which bears the lateral force and forms a rectangular frame foundation with the main keel.

[0035] Second reinforcing plate 4: Welded to the opposite side of the main keel 1, the end away from the main keel is inclined and fixedly connected to the side keel 6, so that the main keel, the side keel and itself form a triangular stable structure, which transmits and disperses longitudinal and lateral forces and enhances the frame's shear resistance.

[0036] Third reinforcing plate 5: The front and rear are respectively set on the opposite sides of the two side keels 6, and the upper and lower surfaces are fixedly connected to the second reinforcing plate 4 to enhance the compressive strength of the upper and lower second reinforcing plates and enhance the connection stability between the side keels.

[0037] First reinforcing plate 3: The upper and lower parts are respectively set on the opposite sides of the two main keels 1, and the left and right ends are fixedly connected to the second reinforcing plate 4 to form a horizontal support structure, which enhances the overall integrity of the frame in the vertical direction and disperses the force transmitted by the second reinforcing plate.

[0038] V-shaped reinforcing rib 2: Fixed to the inner wall of the main keel 1, they are interconnected to form a mesh support. The compressive and bending resistance of the V-shaped structure is used to enhance the connection strength between the web and flange of the H-steel main keel and prevent local deformation of the main keel.

[0039] First mounting hole 7: The holes are formed on the two side keels 6, corresponding to the second mounting holes 8 of the main keel 1, for the insertion of fixing bolts, providing an installation position for the connection between the side keels and the main keel, and ensuring accurate connection.

[0040] Second mounting hole 8: The holes are set on the two main keels 1, corresponding to the first mounting holes 7, for the insertion of fixing bolts. The bolts and nuts are used to firmly connect the main keels and the side keels, ensuring the stability of the connection nodes.

[0041] Fixing bolts: Insert the 6 into the inner wall of the corresponding second mounting hole 8 and the first mounting hole 7, and fix the 6 onto the main keel 1 with a fixing nut on the outer wall to prevent the connection from loosening and ensure stable force transmission.
