Description

Technical Field

[0001] The utility model relates to the technical field of assembled houses, and in particular to a cross beam for assembled buildings. Background Art

[0002] The beams used in prefabricated houses are an important component of prefabricated building structures. They are usually prefabricated in factories and then transported to the construction site for rapid assembly. Together with other prefabricated components (such as columns, wall panels, floor slabs, etc.), they constitute the main structure of the house. Compared with traditional on-site cast beams, prefabricated beams are easier to transport and install.

[0003] The cross beams used in the conventional prefabricated buildings are usually square tube structures, and connecting pieces need to be added when the cross beams are connected to other columns or other prefabricated components, which results in low applicability during the actual assembly process. Utility Model Content

[0004] The utility model provides a cross beam for assembled buildings, which solves the problem of low applicability of cross beams in related technologies.

[0005] The technical solution of the utility model is as follows:

[0006] A crossbeam for assembled buildings, comprising:

[0007] main body;

[0008] A plurality of L-shaped plates are arranged at intervals on the main body. The L-shaped plates have a first side and a second side. The first side abuts against the outer wall of the main body, and the second side has a first through hole.

[0009] Optionally, it also includes:

[0010] There are several U-shaped plates, which are arranged at intervals on the main body. The U-shaped plates have a first bottom plate, a first side edge and a second side edge. The first side edge and the second side edge are respectively located on both sides of the first bottom plate. The first side edge and the second side edge are both perpendicular to the first bottom plate. The first side edge has a second through hole, and the second side edge has a third through hole. The axis of the second through hole is collinear with the axis of the third through hole.

[0011] Optionally, it also includes:

[0012] There are a plurality of hangers which are arranged on the main body at intervals, and the hangers are used for hooking the diagonal braces.

[0013] Optionally, two ends of the main body have fourth through holes.

[0014] Optionally, both ends of the main body further have mounting grooves, and the openings of the mounting grooves are oriented perpendicular to the axis of the fourth through hole.

[0015] Optionally, the main body is a hollow square rectangular tube;

[0016] Optionally, the first through hole is rectangular.

[0017] Optionally, the L-shaped plate, the U-shaped plate and the hanger are all welded to the main body.

[0018] The working principle and beneficial effects of the utility model are:

[0019] In the present invention, the use of the L-shaped plate, on the one hand, abuts against the outer wall of the main body through the first side, and is fixed to the L-shaped plate by welding, riveting or clamping, thereby enhancing the connection rigidity and stability between the L-shaped plate and the main structure, and ensuring the stability of the overall structure. On the other hand, the design of the second side extending out provides an installation interface for subsequent connecting accessories or structural parts, increasing the applicability and flexibility of the crossbeam.

[0020] The L-shaped plate spacing on the main body helps to reduce the weight of the beam while maintaining the necessary strength and stability. The spacing layout can also adjust the position and number of L-shaped plates according to actual project needs to adapt to buildings with different spans and load requirements.

DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0029] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] Reference Figure 1~2 The utility model proposes a prefabricated building beam, including a plurality of L-shaped plates 200, which are spaced apart on a main body 100. The L-shaped plates 200 have a first side 210 and a second side 220. The first side 210 abuts against an outer wall of the main body 100, and the second side 220 has a first through hole 221.

[0031] In this embodiment, the use of the L-shaped plate 200, on the one hand, abuts against the outer wall of the main body 100 through the first side 210, and is fixed to the L-shaped plate 200 by welding, riveting or clamping, thereby enhancing the connection rigidity and stability between the L-shaped plate 200 and the main body 100 structure, and ensuring the stability of the overall structure. On the other hand, the design of the second side 220 extending out not only provides an installation interface for subsequent connection accessories or structural parts, but also allows the bottom plate to be placed on the second side 200, increasing the applicability and flexibility of the crossbeam.

[0032] The L-shaped plates 200 on the main body 100 are arranged at intervals, which helps to reduce the weight of the beam while maintaining the necessary strength and stability. The interval layout can also adjust the position and number of the L-shaped plates 200 according to actual engineering needs to adapt to buildings with different spans and load requirements.

[0033] The second side 220 can not only overlap other prefabricated components, but the first through hole 221 on the second side 220 is also a key connection structure. The first through hole 221 can be used to install bolts, pins or other fasteners to connect other prefabricated components or other beams, making the assembly process more convenient and standardized. The first through hole 221 is more convenient for quick on-site positioning and fixing, reducing the workload of on-site processing and improving installation efficiency.

[0034] Furthermore, it also includes a U-shaped plate 300, which is provided on the main body 100 at intervals. The U-shaped plate 300 has a first bottom plate 310, a first side 320 and a second side 330. The first side 320 and the second side 330 are respectively located on both sides of the first bottom plate 310. The first side 320 and the second side 330 are both perpendicular to the first bottom plate 310. The first side 320 has a second through hole 321, and the second side 330 has a third through hole 331. The axis of the second through hole 321 is collinear with the axis of the third through hole 331.

[0035] In this embodiment, the interval arrangement of the U-shaped plate 300 not only enriches the connection mode of the main body 100, but also improves the interchangeability and versatility of the components. According to specific needs, it is possible to flexibly choose to use the L-shaped plate 200 or the U-shaped plate 300, or a combination of the two, to meet the structural requirements and load conditions of different parts.

[0036] The second through hole 321 on the first side 320 and the second side 330 is colinear with the axis of the third through hole 331. This design simplifies the installation process of the fasteners and ensures that bolts, pins or other fasteners can penetrate in a straight line, which is not only convenient for installation, but also ensures the stability and firmness of the connection. By adding connectors to the first side plate and the second side 330, the connection method and structural layout of the beam can be flexibly adjusted according to specific installation requirements. This design provides a high degree of adaptability for on-site construction, especially when it is necessary to enhance the strength of the structural nodes or adapt to special connection requirements, it can respond and adjust quickly.

[0037] When assembling a house, the beams can be overlapped together through the U-shaped plates 300 to form a planar frame structure.

[0038] In the installation position where higher strength is required, by adding connectors on the side of the U-shaped plate 300, and then juxtaposing the two main bodies 100 and connecting them together through fasteners, this design can significantly improve the overall bearing capacity and stability of the structure. Especially for construction projects with large spans and heavy loads, this parallel reinforcement method can effectively disperse stress, reduce the burden of a single structure, and enhance the bending and shear resistance of the overall structure.

[0039] Furthermore, it also includes a plurality of hangers 400 , which are arranged on the main body 100 at intervals, and the hangers 400 are used to hook the diagonal braces.

[0040] In this embodiment, the hanger 400 is mainly used to connect the diagonal braces, which play a role in increasing lateral stability and preventing lateral displacement in the structure, especially when facing horizontal external forces such as wind loads and earthquakes, and can significantly improve the structure's anti-overturning ability and stability.

[0041] The hangers 400 are arranged at intervals on the main body 100, and the position and number of the diagonal braces can be flexibly selected according to actual engineering requirements. This design is easy to adapt to the structural layout and load conditions of different buildings, especially in projects with complex terrain or special design requirements, and the structural performance can be optimized by adjusting the diagonal brace layout.

[0042] Furthermore, the main body 100 has fourth through holes 110 at both ends.

[0043] In this embodiment, the main body 100 can be connected to the columns through the fourth through holes 110 at both ends by fasteners, so that the beam is not only limited to horizontal expansion, but can also extend upward or downward to form various complex connection structures in three-dimensional space to meet different building layouts and design requirements.

[0044] Furthermore, both ends of the main body 100 further have mounting grooves 120 , and the opening direction of the mounting grooves 120 is perpendicular to the axis of the fourth through hole 110 .

[0045] In this embodiment, the installation grooves 120 at both ends of the main body 100 are convenient for buckling with the longitudinal beam. When the longitudinal beam is fixed, the main body 100 can be buckled with the longitudinal beam through the installation grooves 120, and then the longitudinal beam and the cross beam are fixed by bolts passing through the first through holes 110.

[0046] In actual use, the longitudinal beam can be fixed first, and the main body 100 can be inserted between the longitudinal beams from the upper and lower surfaces or the sides through the installation groove 120. The installation groove 120 can avoid the part of the longitudinal beam used to connect with the cross beam, so that the part of the longitudinal beam connected to the cross beam can enter the installation groove 120 and can be fixed by bolts passing through the first through hole 110.

[0047] Further, the main body 100 is a hollow square rectangular tube;

[0048] In this embodiment, the hollow square rectangular tube structure provides excellent bending and torsion resistance. The square cross-section has uniform stiffness in all directions and is suitable for bearing forces from different directions and for structural requirements with large load-bearing and span.

[0049] The hollow design effectively reduces the deadweight of the beam while maintaining structural strength, making it easier to transport and install, and reducing the burden on the supporting structure.

[0050] Furthermore, the first through hole 221 is rectangular.

[0051] In this embodiment, the processing of the rectangular hole is relatively simple during the manufacturing process, especially when using modern processing technologies such as laser cutting or stamping, it can be completed quickly and accurately, reducing production costs. Compared with circular or square through holes, rectangular through holes provide greater alignment tolerance, which is convenient for adjustment during on-site installation, especially when bolts or other fasteners are used for connection, it is easier to achieve precise docking, improving construction efficiency and connection reliability.

[0052] Furthermore, the L-shaped plate 200 , the U-shaped plate 300 , and the hanger 400 are all welded to the main body 100 .

[0053] In this embodiment, the welding connection makes the L-shaped plate 200, the U-shaped plate 300 and the hanger 400 almost become a whole with the main body 100, which enhances the integrity of the structure, reduces the gaps at the joints, and is beneficial to improving the sealing and durability of the structure and reducing the erosion of the building structure by external environmental factors.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
