Description

Technical Field

[0001] This utility model belongs to the field of building node fixing technology, specifically relating to a fixing structure for modular building nodes. Background Technology

[0002] In the construction industry, prefabricated houses are widely used in various fields such as temporary buildings, residences, and offices due to their advantages such as fast construction speed, relatively low cost, and flexible assembly and disassembly. One of the core structures of prefabricated houses is the fixing structure of its building nodes, especially the connection method between the main beam and the side beam, which is directly related to the stability and safety of the entire building structure.

[0003] In traditional building joint fixing structures, strip-shaped connecting blocks are usually designed on both sides of the main beam. These connecting blocks cooperate with the pre-set strip connecting grooves on the side beams and are then fastened with multiple bolts to achieve the connection between the main beam and the side beam. However, this design has obvious limitations: First, the cooperation method between the strip connecting blocks and the strip connecting grooves lacks an effective limiting mechanism in the lateral direction (i.e., perpendicular to the extension direction of the main beam and the side beam), which makes the connected structure prone to displacement or loosening when subjected to lateral forces, affecting the overall stability of the building. Second, due to the characteristics of the strip structure, the bolt holes on the main beam and the side beam are often difficult to align precisely during the connection process. This not only increases the installation difficulty but may also damage the bolt holes or connectors due to forced alignment, reducing the connection strength. Furthermore, traditional connection methods are also insufficient in tensile strength, making it difficult to meet the safety requirements of high-intensity use environments.

[0004] To address the aforementioned issues, designing a building node fixing structure that can achieve stable lateral positioning of the main beam and side beams, enhance the tensile strength after connection, and improve the alignment accuracy of bolt holes and the convenience of fixed connection operation has become an urgent technical problem to be solved in the field of prefabricated housing construction.

[0026] 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. Example

[0027] Please see Figures 1 to 6 This embodiment of the present utility model provides the following technical solution: a fixed structure for a modular building node, comprising a main beam 3, two side beams 4 disposed on both sides of the main beam 3, and further comprising...

[0028] L-shaped connecting blocks 32 and T-shaped connecting blocks 41 are symmetrically welded and fixed on both sides of the main beam 3. The end surface of the side beam 4 has L-shaped connecting grooves 42 into which the L-shaped connecting blocks 32 slide. T-shaped connecting blocks 41 are welded and fixed between the two L-shaped connecting grooves 42 on the end surface of the side beam 4. T-shaped connecting grooves 31 are also formed between the two L-shaped connecting blocks 32 on both sides of the main beam 3. When the main beam 3 and the side beam 4 are fixedly connected, the T-shaped connecting blocks 41 slide into the T-shaped connecting grooves 41 through the hoisting of the side beam 4. The connecting groove 31 allows the L-shaped connecting block 32 to slide into the L-shaped connecting groove 42, thereby achieving the initial connection between the main beam 3 and the side beam 4 and the initial positioning between the main beam 3 and the side beam 4. This effectively solves the lateral limiting problem during the connection process of the main beam 3 and the side beam 4, ensuring the structural stability after the connection of the main beam 3 and the side beam 4. Furthermore, the L-shaped structural design of the L-shaped connecting block 32 and the L-shaped connecting groove 42, and the T-shaped structural design of the T-shaped connecting block 41 and the T-shaped connecting groove 31, significantly enhance the lateral tensile performance at the connection between the main beam 3 and the side beam 4, improving the overall safety of the building.

[0029] And a fixing plate 1 is set on the top of the main beam 3, and the two ends of the fixing plate 1 extend to the top of the two side beams 4 respectively;

[0030] And L-shaped fastening plates 2 installed on both sides of the main beam 3 and located at the bottom of the side beam 4;

[0031] In addition, there are fixing bolts 5 and fixing nuts 6. The bottom end of the fixing bolts 5 vertically penetrates the fixing plate 1, the side beam 4 and the L-shaped fastening plate 2 and is locked and fixed by the fixing nuts 6, so that the main beam 3 and the side beam 4 can be stably fixed and connected together.

[0032] In this embodiment, preferably, bolt holes A11 for the fixing bolt 5 to pass through are opened on both ends of the fixing plate 1, bolt holes B43 for the fixing bolt 5 to pass through are opened on the end surface of the side beam 4, and bolt holes C22 for the fixing bolt 5 to pass through are opened on the top surface of the L-shaped fastening plate 2, so that the bottom end of the fixing bolt 5 can smoothly pass through the fixing plate 1, the side beam 4 and the L-shaped fastening plate 2 in sequence.

[0033] In this embodiment, preferably, a positioning structure is also included. The positioning structure is disposed between the fixed plate 1 and the main beam 3. The positioning structure includes two positioning blocks 12 welded and fixed to the bottom surface of the fixed plate 1 and two positioning slots 34 opened on the top surface of the main beam 3 for the positioning blocks 12 to be inserted. When the positioning blocks 12 are inserted into the positioning slots 34, the fixed plate 1 is positioned in the horizontal direction. At this time, the bolt hole A11 is aligned with the bolt hole B43 to achieve quick positioning. A transverse mounting groove is opened through the two positioning slots 34. A rubber inner seat 35 is glued and installed in the transverse mounting groove. Both ends of the 5 are provided with an integral arc-shaped positioning protrusion 351, both of which are made of fluororubber and will undergo elastic deformation when squeezed. The side of the positioning block 12 is provided with a positioning groove 121 for the arc-shaped positioning protrusion 351 to be inserted into. When the positioning block 12 is inserted into the positioning slot 34, the arc-shaped positioning protrusion 351 will also be squeezed into the positioning groove 121. This further assists in positioning the positioning block 12 and the fixing plate 1, further improving the ease of installation of the fixing structure, preventing the fixing plate 1 from lateral displacement during installation, and ensuring the rapid and stable alignment of the bolt holes.

[0034] In this embodiment, preferably, rectangular deformation grooves are provided at both ends of the rubber inner seat 35, so that the arc-shaped positioning protrusion 351 has sufficient deformation space when it is squeezed.

[0035] In this embodiment, preferably, a transverse insert 23 is welded and fixed to the outer surface of the L-shaped fastening plate 2, and a transverse insertion hole 33 is provided through the surface of the main beam 3 for the transverse insert 23 to be inserted. During the installation of the L-shaped fastening plate 2, the L-shaped fastening plate 2 can be attached to the side of the main beam 3, and the transverse insert 23 can be inserted into the transverse insertion hole 33, so that the initial positioning of the L-shaped fastening plate 2 can be achieved. At this time, the bolt hole C22 will be aligned with the bolt hole B43, achieving rapid positioning. After cooperating with the positioning structure between the fixing plate 1 and the main beam 3, the bolt hole A11, bolt hole B43 and bolt hole C22 can be quickly and stably aligned, which facilitates the operator to pass through the fixing bolt 5 during the fixing connection process, improves the connection convenience and improves the construction efficiency.

[0036] In this embodiment, preferably, two stiffening plates 21 are symmetrically welded and fixed on the inner surface of the L-shaped fastening plate 2, and the fixing nut 6 is located between the two stiffening plates 21. The stiffening plates 21 can provide stable support and reinforcement for the inner side of the L-shaped fastening plate 2, ensuring the structural strength stability of the L-shaped fastening plate 2, while not affecting the normal connection of the fixing bolt 5 and the fixing nut 6.
