Description

Technical Field

[0001] The utility model relates to the technical field related to construction, and in particular to a supporting beam structure of a wooden structure building. Background Art

[0002] Beam structure refers to a connection structure used for support and reinforcement in the field of construction. Beam structure is usually used to withstand shear force and bending moment to enhance the stability and load-bearing capacity of the structure. Beam structure is generally made of materials such as steel, concrete or wood, and has the characteristics of high strength and corrosion resistance.

[0003] In some construction processes, it is necessary to consider that the beam structure has good supporting performance and lightweight design. In the prior art, in order to have both the supporting performance and lightweight design of the beam structure, a solution of reducing the material usage is generally adopted. For example, under the condition of meeting the stiffness and bearing capacity, the supporting beam is designed as a hollow beam structure to reduce the weight of the beam structure, or the structural design of the beam is optimized, or a beam structure of different materials is selected. However, such solutions are all improved by improving the raw materials or materials. The prior art lacks a beam structure that can reduce costs and weight while having strong versatility. For example, the Chinese patent application number CN200810094027.6 discloses a hollow beam and a bridge body using the hollow beam. By improving the material of the beam and setting the beam as a hollow structure, a lightweight beam structure is achieved. However, such a beam structure can only be applied to specific structures and has a high cost.

[0004] Therefore, the prior art lacks a beam structure that can reduce cost and weight while having high versatility. Utility Model Content

It also includes a truss assembly, which is arranged below the top beam and between the top beam and the support columns; the truss assembly includes at least two groups of truss connection groups, and each truss connection group extends obliquely from the top beam toward a support column, one end is fixedly connected to the top beam, and the other end is fixedly connected to a support column. Wherein, each truss connection group includes at least two trusses arranged in parallel and at intervals, each truss extends obliquely from the top beam toward a support column, and one end of at least one truss in the truss connection group is fixedly connected to the top beam, and the other end of at least one truss is fixedly connected to the support column.

[0007] At least two truss connection groups extend obliquely from the top beam toward different support columns in a cross manner, and the angle between each truss and the top beam is within the range of 0 to 30 degrees.

[0008] By adopting the above technical solution, the support beam structure of the wooden structure building provided by the present application can significantly enhance the structural stability due to the arrangement of the truss assembly. Further, the truss assembly includes trusses arranged in parallel and at intervals, and at least two groups of truss connection groups extending obliquely from the top beam toward different support columns to cross each other. Through the design of this structure, the beam structure is more solid and stable, avoiding structural deformation and damage, and ensuring the service life and safety of the structure. At the same time, it also has excellent load-bearing capacity. The truss assembly can withstand horizontal loads and vertical loads, and transfer the loads to other supporting structures, thereby enhancing the load-bearing capacity of the entire structure. Furthermore, the support beam structure disclosed in the present application can also disperse the load, evenly distributing the load of the stress point to more supporting structures, reducing the situation of structural force concentration, thereby avoiding premature fatigue and damage of the structure.

[0009] Preferably, in the two truss connection groups that are cross-fixed to each other, the length of any one of the two parallel trusses in one truss connection group is greater than the spacing between the two parallel trusses in the other truss connection group. This structural design can ensure that the two trusses of at least two truss connection groups can cross each other and extend obliquely.

[0010] An embodiment of the utility model also discloses a supporting beam structure of a wooden structure building, wherein the top beam includes two top beam monomers in the length direction, the opposite connecting ends of the two top beam monomers are fixedly connected to each other, and the two top beam monomers are symmetrically arranged relative to the connecting part, wherein the angle between the two top beam monomers is in the range of 140° to 180°.

By jointly bearing the load and transmitting the force, they effectively reduce the deformation and displacement that may occur when a single beam is subjected to force, improve the stability of the structure, and reasonably distribute the load to prevent a certain beam from being subjected to excessive pressure or tension. The setting of parallel beams increases the redundancy of the structure, that is, when one of the beams has a problem, the other beams can still continue to support the structure to prevent the overall failure of the structure. Finally, the space utilization is optimized and the overall performance of the structure is enhanced.

[0016] Further preferably, an auxiliary fixing truss is provided under each top beam unit, the auxiliary fixing truss is located outside the support column, one end of the auxiliary fixing truss is fixedly connected to the top beam unit, and the other end extends away from a corresponding support column.

[0040] Beam structure refers to a connection structure used for support and reinforcement in the field of construction. Beam structure is usually used to withstand shear force and bending moment to enhance the stability and load-bearing capacity of the structure. In the existing construction process, especially in wooden structures, the support performance and stiffness of the support beams are generally poor, and it is difficult to simultaneously meet the advantages of lightweight and good support performance.

[0041] Therefore, the utility model provides a supporting beam structure of a wooden structure building which can reduce cost and weight while having high versatility. By arranging staggered truss components on the supporting beam structure, the truss components provide structural safety and stability while enriching the structural form and also demonstrating the flexible arrangement characteristics of the trusses.

[0042] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] The implementation of this embodiment discloses a support beam structure of a wood structure building, including a top beam 100 and at least two support columns 200 arranged at intervals, the top beam 100 is mounted on the support columns 200, and the support columns 200 provide support for the top beam 100 in the vertical direction. It also includes a truss assembly 300, which is arranged below the top beam 100 and between the top beam 100 and the support columns 200; the truss assembly 300 includes at least two groups of truss connection groups, and each truss connection group extends obliquely from the top beam 100 toward one support column 200, one end of which is fixedly connected to the top beam 100, and the other end of which is fixedly connected to one support column 200. Among them, each truss connection group includes at least two trusses 310 arranged parallel to each other and spaced apart, each truss 310 extends obliquely from the top beam 100 toward a support column 200, and one end of at least one truss 310 in the truss connection group is fixedly connected to the top beam 100, and the other end of at least one truss 310 is fixedly connected to the support column 200.

[0044] At least two truss connection groups extend from the top beam 100 toward different support columns 200 in a cross-shaped and oblique manner, and the angle between each truss 310 and the top beam 100 is in the range of 0 to 30 degrees.

[0045] Specifically, in this embodiment, in order to ensure the supporting effect of the support columns 200 on the top beam 100, the number of the support columns 200 is preferably set to an even number, for example, the support columns 200 can be set to 2, 4, 6 or other numbers. Furthermore, the angle between each truss 310 and the top beam 100 can be 10°, 15°, 20°, 30° or other inclination angles, and this embodiment does not make any specific limitation on this.

[0046] Next, see Figure 1 As one of the implementation methods of the supporting beam structure of the wooden structure building, the truss assembly 300 is arranged below the top beam 100 and between the top beam 100 and the supporting column 200, and the truss assembly 300 includes two groups of truss connection groups, each group of truss connection groups includes two mutually parallel trusses 310, the interval size of the two mutually parallel trusses 310 is smaller than the length size of the trusses 310, and a closed parallelogram is formed between the two groups of trusses 310, and Figure 1 In one of the implementations shown, two ends of each truss 310 are fixedly connected to the top beam 100 and the support column 200 , respectively, so as to provide good support for the top beam 100 .

[0047] The support beam structure of the wooden structure building provided by the present application can significantly enhance the structural stability due to the provision of the truss assembly 300. The parallel spaced trusses 310 and at least two groups of truss connection groups extend obliquely from the top beam 100 toward different support columns 200 in a cross-wise manner. Through the design of this structure, the beam structure is more solid and stable, avoiding structural deformation and damage, and ensuring the service life and safety of the structure. At the same time, it also has excellent load-bearing capacity. The truss assembly 300 can withstand horizontal loads and vertical loads, and transfer the loads to other supporting structures, thereby enhancing the load-bearing capacity of the entire structure. Furthermore, the support beam structure disclosed in the present application can also disperse the load, evenly distributing the load of the stress point to more supporting structures, reducing the situation of structural force concentration, thereby avoiding premature fatigue and damage of the structure.

[0048] Further preferably, in the two truss connection groups that are cross-fixed to each other, the length dimension of any one of the two trusses 310 arranged in parallel in one truss connection group is greater than the spacing dimension between the two trusses 310 arranged in parallel in the other truss connection group. This structural design can ensure that the two trusses 310 of at least two truss connection groups can cross each other and extend obliquely.

[0049] For example, in two groups of truss connection groups that are cross-fixed to each other, the size of each truss 310 is 3m, and the spacing distance in any group of truss connection groups is only set to 0.2m, 0.3m, 0.5m or other spacings, ensuring that the length of each truss 310 is greater than the spacing between two adjacent trusses 310, thereby ensuring that the truss assembly 300 is connected in a parallel cross manner.

[0050] The implementation method of this embodiment also discloses a supporting beam structure of a wooden structure building, see Figure 2 The top beam 100 includes two top beam monomers 110 in the length direction, the opposite connecting ends of the two top beam monomers 110 are fixedly connected to each other, and the two top beam monomers 110 are symmetrically arranged relative to the connecting position, wherein the angle between the two top beam monomers 110 is in the range of 140° to 180°.

[0051] The two top beam units 110 can be fixedly connected by means of screw connection, mortise and tenon structure connection, etc. The angle between the two top beam units 110 can be 140°, 160°, 170°, 180° or any value within the range of 140° to 180°. Through the design of the above structure, the two top beam units 110 are arranged to increase the coverage area of ​​the top beam 100 and improve the drainage performance of the top beam 100.

In the two groups of truss connection groups below one top beam unit 110, one end of one truss connection group is fixed to the connection end of the top beam unit 110, and the other end extends toward the support column 200 supporting the top beam unit 110 and is fixedly connected to the support column 200, and one end of the other truss connection group is fixed to the support column 200, and the other end extends toward the bottom of another top beam unit 110 and is fixedly connected to one end of the corresponding truss connection group below the other top beam unit 110. In the two groups of truss connection groups below one top beam unit 110, each group of truss connection groups includes two trusses 310 arranged parallel to each other and spaced apart, and the trusses 310 in the two groups of truss assemblies 300 are cross-fixedly connected and form a closed parallelogram at the cross-connection position.

By jointly bearing the load and transmitting the force, they effectively reduce the deformation and displacement that may occur when a single beam is subjected to force, improve the stability of the structure, and reasonably distribute the load to prevent a certain beam from being subjected to excessive pressure or tension. The arrangement of parallel beams increases the redundancy of the structure, that is, when one of the beams has a problem, the other beams can still continue to support the structure to prevent the overall failure of the structure. Finally, the space utilization is optimized and the overall performance of the structure is enhanced.

The structural connection method in which a plurality of second connection members surround the first connection member can increase the connection strength and stability of the connection part, and can also prevent the truss 310 from rotating relative to the support column 200 after being connected and fixed.

[0058] Further preferably, see Figure 4 One end of each truss 310 is in contact with the top beam 100 or one end of the truss 310 is partially embedded in the top beam 100, and a connection assembly is provided at the portion where the truss 310 and the top beam 100 are connected.
