Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a rigid splicing structure. Background Technology

[0002] Portal frames are a type of lightweight steel structure system for housing. They typically utilize energy-saving and environmentally friendly new building materials, are prefabricated in sections in a factory, and then assembled on-site as needed. In traditional construction methods, adjacent portal frames are mainly fixed by welding workers, but manual welding is less effective, resulting in lower connection strength between adjacent portal frames.

[0003] The related technology proposes a reinforcement structure in which connecting plates are installed on adjacent portal frames. The two adjacent connecting plates are mechanically locked by fastening bolts. At the same time, a welding plate is added between the adjacent connecting plates for secondary welding and fixing, which improves the connection strength between adjacent portal frames.

[0004] However, the area of ​​the connecting end plate in the above-mentioned reinforcement structure is small, and the connection between adjacent portal frames relies only on the small area of ​​the connecting end plate. When the portal frame is under load, the connection end plate is prone to failure due to stress concentration, and the connection reliability between adjacent portal frames is poor. Utility Model Content

[0005] The purpose of this invention is to provide a rigid splicing structure that can improve connection reliability and connection strength.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model proposes a rigid splicing structure, including:

[0008] The first rigid unit includes a first web and two first flanges, the two first flanges being connected by the first web, and the first web and the two first flanges forming a first receiving groove.

[0009] The second rigid unit includes a second web and two second flanges. The two second flanges are connected by the second web. The second web and the two second flanges form a second receiving groove. The bottom of the second receiving groove is flush with the bottom of the first receiving groove and they are interconnected. The second web is connected to the first web. The two first flanges are connected to the two second flanges one by one.

[0010] The rigid reinforcement unit includes a rigid reinforcement member and multiple connectors. The rigid reinforcement member is embedded in a first receiving groove and a second receiving groove. At least a portion of the rigid reinforcement member abuts against a first web and a second web. The rigid reinforcement member is connected and fixed to the first rigid unit and the second rigid unit through multiple connectors.

[0011] Preferably, the rigid reinforcement includes a first reinforcement part, a second reinforcement part, and a third reinforcement part that are fixedly connected in sequence. The first reinforcement part abuts against one of the first flanges of the first rigid unit and a second flange connected thereto. The second reinforcement part abuts against the first web and the second web. The third reinforcement part abuts against the other first flange of the first rigid unit and a second flange connected thereto.

[0012] Specifically, the rigid splicing structure also includes a first limiting member and a second limiting member. The first limiting member and the first reinforcing part are disposed on opposite sides of one of the first flanges of the first rigid unit and are connected to each other. The second limiting member and the third reinforcing part are disposed on opposite sides of the other first flange of the first rigid unit and are connected to each other.

[0013] More specifically, the length of the first limiting member is not less than the length of the first reinforcing part, and the length of the second limiting member is not less than the length of the third reinforcing part.

[0014] Optionally, the length of the second reinforcement is greater than the distance between the two first flanges.

[0015] Optionally, the rigid splicing structure also includes a seal, which is sandwiched between the connector and the first rigid unit and / or the second rigid unit.

[0016] Optionally, the two first flanges are parallel to each other and spaced apart, and both first flanges are perpendicular to the first web. The two second flanges are parallel to each other and spaced apart, and both second flanges are perpendicular to the second web.

[0017] Alternatively, the rigid reinforcement may be made of alloy steel.

[0018] The beneficial effects of this utility model are:

[0019] This invention proposes a rigid splicing structure. A first rigid unit includes a first receiving groove, and a second rigid unit includes a second receiving groove connected to the first receiving groove. Rigid reinforcement members are embedded in the first and second receiving grooves. The bottoms of the first and second receiving grooves are flush and at least partially abut against the first and second web plates, allowing the rigid reinforcement members to form continuous surface contact with the first and second web plates after being embedded. This enables the load to be evenly transferred to the first and second rigid units through the rigid reinforcement members, reducing stress concentration at the connection point and improving the connection reliability of the first and second rigid units. Furthermore, based on the one-to-one connection between the first flange and the first web plate of the first rigid unit and the second flange and second web plate of the second rigid unit, connecting and fixing the rigid reinforcement members to the first and second rigid units using multiple connectors further enhances the connection strength between the first and second rigid units.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Portal frames are a type of lightweight steel structure system for housing. They typically utilize energy-saving and environmentally friendly new building materials, are prefabricated in sections in a factory, and then assembled on-site as needed. In traditional construction methods, adjacent portal frames are often fixed by manual welding. Taking the splicing of steel columns in a portal frame as an example, in actual construction scenarios, the dimensions of the web and flange plates of the upper and lower steel columns often differ. The connection effect of the upper and lower steel columns depends on the welding skill of the workers. Manual welding usually presents two major technical challenges: firstly, the connection strength between the upper and lower steel column sections is insufficient; secondly, the verticality deviation between the upper and lower steel columns is usually large, making it easy for safety hazards to occur during the subsequent use of the portal steel columns.

[0034] To improve connection strength and reliability, such as Figures 1-3 As shown, this utility model provides a rigid splicing structure, including a first rigid unit 1, a second rigid unit 2, and a rigid reinforcement unit 3. The first rigid unit 1 includes a first web 11 and two first flanges 12, which are connected by the first web 11. The first web 11 and the two first flanges 12 form a first receiving groove. The second rigid unit 2 includes a second web 21 and two second flanges 22, which are connected by the second web 21. The second web 21 and the two second flanges 22 form a... The second receiving groove is flush with and connected to the bottom of the first receiving groove. The second web 21 is connected to the first web 11. The two first flanges 12 are connected to the two second flanges 22 in a one-to-one correspondence. The rigid reinforcement unit 3 includes a rigid reinforcement member 31 and a plurality of connectors 32. The rigid reinforcement member 31 is embedded in the first receiving groove and the second receiving groove. At least a portion of the rigid reinforcement member 31 abuts against the first web 11 and the second web 21. The rigid reinforcement member 31 is connected and fixed to the first rigid unit 1 and the second rigid unit 2 through the plurality of connectors 32. For example, the connectors 32 are high-strength bolts or ring groove rivets, etc.

[0035] In this embodiment, the rigid reinforcement 31 is embedded in the first and second receiving grooves. The bottoms of the first and second receiving grooves are flush and at least partially abut against the first web 11 and the second web 21. This ensures that after the rigid reinforcement 31 is embedded in the first and second receiving grooves, it can achieve continuous surface contact with the first web 11 and the second web 21, ensuring a continuous load transmission path at the joint of the first rigid unit 1 and the second rigid unit 2. This avoids stress abrupt changes due to structural misalignment and improves the connection reliability of the first rigid unit 1 and the second rigid unit 2 when bearing load. Based on the one-to-one connection between the first flange 12 and the first web 11 of the first rigid unit 1 and the second flange 22 and the second web 21 of the second rigid unit 2, connecting and fixing the rigid reinforcement 31 to the first rigid unit 1 and the second rigid unit 2 through multiple connectors 32 can further improve the connection strength between the first rigid unit 1 and the second rigid unit 2. The first web 11 and the two first flanges 12 form a first receiving groove, and the second web 21 and the two second flanges 22 form a second receiving groove, giving the first rigid unit 1 and the second rigid unit 2 high bending and shear resistance. The flush bottoms of the first and second receiving grooves provide a clear reference for workers' assembly operations, effectively reducing the verticality deviation of the first rigid unit 1 and the second rigid unit 2. Furthermore, the fact that the first rigid unit 1 and the second rigid unit 2 are processed separately and then connected to each other meets the requirements for segmented processing of large components, reducing transportation difficulties.

[0036] Preferably, the rigid reinforcement 31 includes a first reinforcement 311, a second reinforcement 312, and a third reinforcement 313 that are fixedly connected in sequence. The first reinforcement 311 abuts against one of the first flanges 12 of the first rigid unit 1 and a second flange 22 connected thereto. The second reinforcement 312 abuts against the first web 11 and the second web 21. The third reinforcement 313 abuts against the other first flange 12 of the first rigid unit 1 and a second flange 22 connected thereto. For ease of description, the first rigid unit 1 has a first flange 12 on its first side and another first flange 12 on its second side. The second rigid unit 2 has a second flange 22 on its first side and another second flange 22 on its second side. The first flanges 12 and second flanges 22 on the first side are connected to each other, and the first flanges 12 and second flanges 22 on the second side are also connected to each other. The first reinforcing part 311 abuts against the first flange 12 and the second flange 22 connected to the first side, the third reinforcing part 313 abuts against the first flange 12 and the second flange 22 connected to the second side, and the second reinforcing part 312 abuts against the first web plate 11 and the second web plate 21. That is, the rigid reinforcing part 31 can completely cover the splice of the first rigid unit 1 and the second rigid unit 2, thereby comprehensively improving the connection reliability and connection strength of the splice of the first rigid unit 1 and the second rigid unit 2.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, the rigid splicing structure also includes a first limiting member 4 and a second limiting member 5. The first limiting member 4 and the first reinforcing part 311 are disposed on opposite sides of one of the first flanges 12 of the first rigid unit 1 and are connected to each other. The second limiting member 5 and the third reinforcing part 313 are disposed on opposite sides of the other first flange 12 of the first rigid unit 1 and are connected to each other. That is, the first limiting member 4 and the first reinforcing part 311 are connected to each other and are respectively located on the inner and outer sides of the first side of the first rigid unit 1. The first limiting member 4 can improve the deformation resistance of the first flange 12 on the first side of the first rigid unit 1 when the rigid splicing structure is under load. The second limiting member 5 and the third reinforcing part 313 are connected to each other and are respectively located on the inner and outer sides of the second side of the first rigid unit 1. The second limiting member 5 can improve the deformation resistance of the first flange 12 on the second side of the first rigid unit 1 when the rigid splicing structure is under load. Preferably, the first limiting member 4 can be connected to the second flange 22 on the first side of the second rigid unit 2, and the second limiting member 5 can be connected to the second flange 22 on the second side of the second rigid unit 2, thereby improving the deformation resistance of the second flanges 22 on both sides of the second rigid unit 2 and further enhancing the load-bearing capacity of the rigid splicing structure. The first reinforcing part 311 and the first limiting member 4 can be locked and fixed by locking bolts, and the third reinforcing part 313 and the second limiting member 5 can also be locked and fixed by locking bolts.

[0038] More specifically, the length of the first limiting member 4 is not less than the length of the first reinforcing part 311, and the length of the second limiting member 5 is not less than the length of the third reinforcing part 313, so that the first limiting member 4 can completely cover the stress-deformation area of ​​the first reinforcing part 311 and the second limiting member 5 can completely cover the stress-deformation area of ​​the third reinforcing part 313, thereby avoiding structural deformation of the first reinforcing part 311 and the third reinforcing part 313 due to local stress concentration and ensuring the overall load-bearing stability of the rigid splicing structure.

[0039] Optionally, the length of the second reinforcing part 312 is greater than the distance between the two first flanges 12, ensuring that the second reinforcing part 312 forms an interference fit when it is close to the first web plate 11 and the second web plate 21, so as to avoid the second reinforcing part 312 from loosening relative to the first rigid unit 1 and / or the second rigid unit 2 due to vibration or load changes, thereby improving the overall structural stability of the rigid splicing structure.

[0040] In this embodiment, the rigid splicing structure also includes multiple sealing elements. Each sealing element is sandwiched between the connector 32 and the first rigid unit 1 and / or the second rigid unit 2. The sealing elements not only ensure a sealed connection between the connector 32 and the first rigid unit 1 and / or the second rigid unit 2, but also prevent connection failure at the connection node due to structural corrosion or other reasons. For example, near the splicing area of ​​the first rigid unit 1 and the second rigid unit 2, when multiple connectors 32 are used to fix the rigid reinforcement 31, sealing elements need to be sandwiched between the connector 32 and the first rigid unit 1, as well as between the connector 32 and the second rigid unit 2, to improve the reliability and structural durability of the rigid splicing structure under complex working conditions. The sealing elements can be rubber gaskets or rubber pads.

[0041] Optionally, such as Figure 2 and Figure 3 As shown, both the first rigid unit 1 and the second rigid unit 2 are H-shaped steel columns, meaning that the two first flanges 12 are parallel and spaced apart, and both first flanges 12 are perpendicular to the first web 11. The two second flanges 22 are parallel and spaced apart, and both second flanges 22 are perpendicular to the second web 21. This gives the first rigid unit 1 and the second rigid unit 2 high bending stiffness and good compressive stability along their length. Compared to other irregularly shaped components, the connection construction is easier and the processing is more convenient. It is understood that to enhance the reinforcement effect of the rigid reinforcement member 31 on the H-shaped first rigid unit 1 and the second rigid unit 2, the rigid reinforcement member 31 should be U-shaped, meaning that the first reinforcement part 311 and the third reinforcement part 313 are parallel and spaced apart, and both the first reinforcement part 311 and the third reinforcement part 313 are perpendicular to the second reinforcement part 312.

[0042] Optionally, the rigid reinforcement 31 may be made of alloy steel, which has advantages such as high strength, high toughness, wear resistance, corrosion resistance and strong temperature adaptability, and can be used in a variety of application scenarios.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
