Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a multi-beam frame structure. Background Technology

[0002] A reinforced concrete frame structure is a load-bearing component formed by using steel pipes as an outer skeleton and filling the interior with concrete. It not only significantly reduces concrete cracking but also enhances the supporting effect of the outer steel pipes.

[0003] The joints between precast components are the force transmission nodes of prefabricated concrete frame structures, and also the weakest load-bearing parts. The reliability of these joints directly affects the stability and safety of the entire structure. Traditional methods for connecting main and secondary beams include using slab joints, pre-reserved slots in main beams, and pre-reserved post-cast sections in secondary beams. These methods all suffer from a series of problems, such as low component standardization, high difficulty in design, processing, and construction, and difficulty in ensuring construction quality. Furthermore, on-site formwork and support are required, resulting in low installation efficiency and making it difficult to fully utilize the inherent advantages of prefabricated concrete structures. Utility Model Content

[0004] The main purpose of this invention is to propose a multi-beam frame structure that aims to reduce the assembly difficulty between the main and secondary beams.

[0005] To achieve the above objectives, the multi-beam frame structure includes at least one first connecting beam and at least one second connecting beam, one of which has a prefabricated connector configured to connect the first connecting beam and the second connecting beam.

[0006] In one embodiment of the present invention, the first connecting beam is provided with a plurality of prefabricated connectors, each of the prefabricated connectors connecting a first connecting beam and a second connecting beam.

[0007] In one embodiment of this utility model, a plurality of the prefabricated connectors are spaced apart.

[0008] In one embodiment of the present invention, the prefabricated connector includes a fixed frame and a plurality of pre-set screw holes, all of which are provided on the connecting side of the fixed frame; the fixed frame is configured to screw the first connecting beam or the second connecting beam.

[0009] In one embodiment of the present invention, the fixed frame includes a fixed bottom edge and three reinforcing sides, the fixed bottom edge and the three reinforcing sides are an integral structure, two of the reinforcing sides are located opposite each other on both sides of the fixed bottom edge, and one of the reinforcing sides is located on the bottom side of the fixed bottom edge; the fixed bottom edge is provided with the pre-set screw hole.

[0010] In one embodiment of the present invention, each of the reinforcing sides is provided with a plurality of reinforcing ribs, and each reinforcing rib and the reinforcing side are integrally formed.

[0011] In one embodiment of the present invention, a plurality of reinforcing ribs are spaced apart along the length direction of the reinforcing side, and each reinforcing rib extends along the width direction of the reinforcing side.

[0012] In one embodiment of the present invention, the fixed bottom edge and the three reinforcing side edges enclose a receiving groove, which is configured to receive the first connecting beam or the second connecting beam.

[0013] In one embodiment of this utility model, a plurality of the pre-set screw holes are evenly arranged on the fixed frame.

[0014] In one embodiment of the present invention, the prefabricated connector is disposed on the first connecting beam, and the second connecting beam connects the prefabricated connector and has a reserved gap between them, the reserved gap being configured to be filled with a fixing medium.

[0015] In this technical solution, the first connecting beam, the second connecting beam, and the prefabricated connectors are all mass-produced in a factory, ensuring that the dimensions are within a certain error range and reducing assembly difficulty. By setting the prefabricated connectors, the concrete in the core area of ​​the node can play a good restraining role, reducing the shear deformation of the concrete in the core area of ​​the node.

[0027] Please see Figures 1 to 4The multi-beam frame structure includes at least one first connecting beam 10 and at least one second connecting beam 20, one of which has a prefabricated connector 30 configured to connect the first connecting beam 10 and the second connecting beam 20.

[0028] In this technical solution, the first connecting beam 10, the second connecting beam 20, and the prefabricated connector 30 are all mass-produced in a factory, ensuring that the dimensions are within a certain error range and reducing assembly difficulty. By setting the prefabricated connector 30, the concrete in the core area of ​​the node can play a good restraining role, reducing the shear deformation of the concrete in the core area of ​​the node. At the same time, the prefabricated connector 30 realizes dry connection, no formwork or support required, which is convenient for installation, simple in process, and effectively saves working time. During on-site construction, there is no wet operation, which greatly reduces construction dust and construction waste, greatly reduces the impact on surrounding residents and the ecological environment, and alleviates the pressure of maintaining stability.

[0029] It is understood that the first connecting beam 10 and the second connecting beam 20 can be the main beam and the secondary beam, respectively, or the first connecting beam 10 and the second connecting beam 20 can be the secondary beam and the main beam, respectively. The terms "first" and "second" in this utility model are merely qualifiers used to facilitate the explanation of this technical solution. Of course, in actual construction projects, when the first connecting beam 10 is the main beam and the second connecting beam 20 is the secondary beam, the two will differ in terms of size, load-bearing capacity, placement, etc. Since this is not directly related to the concept of this invention, it will not be explained further here.

[0030] In this utility model, the first connecting beam 10, the second connecting beam 20, and the prefabricated connector 30 are all prefabricated in the factory. Depending on the actual usage requirements of the beams, the prefabricated connector 30 can be located on the first connecting beam 10 (in which case, the first connecting beam 10 is the main beam), or it can be located on the second connecting beam 20 (in which case, the second connecting beam 20 is the main beam), and this is not limited here. In one embodiment, to improve the connection strength between the prefabricated connector 30 and the first connecting beam 10 or the second connecting beam 20, the prefabricated connector 30 and the first connecting beam 10 or the second connecting beam 20 can be integrally connected by welding, die casting, or other methods. In another embodiment, to facilitate the replacement of the prefabricated connector 30, the prefabricated connector 30 and the first connecting beam 10 or the second connecting beam 20 can be detachably connected by a bolt structure. Based on the above two embodiments, the connection method between the prefabricated connector 30 and the first connecting beam 10 or the second connecting beam 20 is not limited here. Preferably, the connection method between the connecting beam and the prefabricated connector 30 is a bolt connection.

[0031] In one embodiment, please refer to Figure 1The first connecting beam 10 is provided with multiple prefabricated connectors 30. Each prefabricated connector 30 connects a first connecting beam 10 and a second connecting beam 20. Specifically, the arrangement direction of the multiple prefabricated connectors 30 can be customized according to the distribution position of the multiple second connecting beams 20 on a first connecting beam 10. For example, if the multiple second connecting beams 20 need to be arranged along the length direction of the first connecting beam 10, then the multiple prefabricated connectors 30 are arranged along the length direction of the first connecting beam 10 so that each prefabricated connector 30 connects a first connecting beam 10 and a second connecting beam 20. Alternatively, if the first connecting beam 10 needs to be provided with multiple second connecting beams 20 in a certain functional area due to functional requirements (such as the arrangement of cross beams), then the multiple prefabricated connectors 30 are concentrated in that functional area so that each prefabricated connector 30 connects a first connecting beam 10 and a second connecting beam 20. The structural topology can be flexibly adjusted by the number of prefabricated connectors 30 to improve design adaptability.

[0032] Further, please refer to Figure 1 Multiple prefabricated connectors 30 are spaced apart. This spacing ensures that each prefabricated connector 30 has enough space for installation and fixation, avoiding mutual interference. At the same time, the spacing can be adjusted according to actual needs to adapt to different beam lengths and stress conditions. In addition, the spacing helps to improve the stability and load-bearing capacity of the multi-beam frame structure and prevent stress concentration problems caused by excessively dense nodes.

[0033] In one embodiment, please refer to Figure 2 The prefabricated connector 30 includes a fixed frame and multiple pre-set screw holes 30a, all of which are located on the connection side of the fixed frame. The fixed frame is configured to screw onto the first connecting beam 10 or the second connecting beam 20. The fixed frame is made of galvanized flat steel, which has good corrosion resistance and strength, making it suitable for use in building structures to ensure the stability and durability of the connection. Multiple pre-set screw holes 30a are provided on the connection side of the fixed frame. At the same time, multiple prefabricated bolts are provided in the first connecting beam 10 or the second connecting beam 20, so that the prefabricated connector 30 can be quickly disassembled and fixed to the first connecting beam 10 or the second connecting beam 20.

[0034] Specifically, please refer to Figure 2The fixed frame includes a fixed bottom edge 31 and three reinforcing sides 32. The fixed bottom edge 31 and the three reinforcing sides 32 are an integral structure. Two reinforcing sides 32 are located opposite each other on both sides of the fixed bottom edge 31, and one reinforcing side 32 is located on the bottom side of the fixed bottom edge 31. The fixed bottom edge 31 is provided with pre-set screw holes 30a. The fixed bottom edge 31 and the reinforcing sides 32 can be formed into an integral structure by hot-rolled steel plate stamping or casting process, eliminating potential weak points of welded joints. The reinforcing sides 32 symmetrically distributed on both sides of the fixed bottom plate can provide lateral constraints in opposite directions. The reinforcing sides 32 located at the bottom of the fixed bottom plate can enhance the bending resistance of the frame.

[0035] Further, please refer to Figure 2 Each reinforced side 32 is provided with multiple reinforcing ribs 33. Each reinforcing rib 33 is an integral structure with the reinforced side 32. By forming an integral structure with the reinforced side 32, not only is the rigidity and strength of the fixed frame improved, but its bending resistance and lateral restraint capacity are also enhanced, thereby ensuring the stability and reliability of the entire multi-beam frame structure.

[0036] In one embodiment, please refer to Figure 2 Multiple reinforcing ribs 33 are spaced apart along the length of the reinforcing side 32, and each reinforcing rib 33 extends along the width of the reinforcing side 32. The spaced reinforcing ribs 33 along the length of the reinforcing side 32 can evenly distribute the stress on the entire reinforcing side 32, avoiding stress concentration on one or a few points, thereby improving the stability and load-bearing capacity of the structure. The extension of each reinforcing rib 33 along the width of the reinforcing side 32 can also enhance the torsional resistance of the reinforcing side 32, making the fixed frame more stable when subjected to torsional forces. In this way, multiple reinforcing ribs 33 enable the fixed frame to adapt to different construction needs and environmental conditions, and maintain good performance whether under heavy loads or special working conditions such as vibration.

[0037] In one embodiment of this utility model, please refer to Figure 1 and Figure 2A fixed bottom edge 31 and three reinforcing side edges 32 enclose a receiving groove 30b, which is configured to accommodate either the first connecting beam 10 or the second connecting beam 20. Specifically, the shape and size of the receiving groove 30b match the first connecting beam 10 or the second connecting beam 20, ensuring that the connecting beam can be tightly embedded within it. Thus, the receiving groove 30b not only provides physical space but also enhances the stability of the connection through structural fit. Simultaneously, the design of the receiving groove 30b allows the first connecting beam 10 or the second connecting beam 20 to be securely encased by the fixed frame during installation, reducing potential displacement or loosening during use. This tight fit helps improve the stability and load-bearing capacity of the entire structure. At the installation level, because the shape of the receiving groove 30b matches the connecting beam, the installation process becomes simpler and faster. The connecting beam can be directly inserted into the receiving groove 30b and then further secured by bolts or other fixing methods, reducing alignment and adjustment time.

[0038] In one embodiment, please refer to Figure 2 Multiple pre-set screw holes 30a are evenly distributed on the fixed frame. This even distribution ensures that each screw hole is evenly stressed during connection, avoiding structural deformation or damage caused by uneven stress. Through multiple evenly distributed screw holes, the fixed frame can achieve multi-point connection with the first connecting beam 10 or the second connecting beam 20. This multi-point connection method significantly enhances the stability and load-bearing capacity of the structure, ensuring the reliability of the connection under various working conditions.

[0039] In one embodiment of this utility model, please refer to Figure 4 A prefabricated connector 30 is provided on the first connecting beam 10. The second connecting beam 20 connects to the prefabricated connector 30 and has a reserved gap between them. The reserved gap is configured to be filled with a fixing medium. Specifically, a reserved gap is provided between the prefabricated connector 30 and the second connecting beam 20. This gap provides space for filling the fixing medium. At the same time, this design allows for fine-tuning during installation to ensure that the second connecting beam 20 can be accurately aligned and fixed in the predetermined position. The fixing medium (such as concrete) filled in the reserved gap can tightly bond the second connecting beam 20 and the prefabricated connector 30 together after curing, enhancing the stability and load-bearing capacity of the overall structure. By reserving the gap and filling it with a fixing medium, this connection method not only relies on the mechanical fixing of the prefabricated connector 30, but also increases the chemical and physical fixing effect of the concrete, making the connection more robust and able to withstand greater loads and stresses.

[0040] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
