Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a steel-wood structural beam for roofs. Background Technology

[0002] Steel-wood structural beams are building structural components that combine steel and wood. They combine the high strength of steel with the environmental friendliness and aesthetics of wood, and are widely used in modern buildings. The high strength of steel allows it to serve as the main load-bearing component, improving the overall strength of the structure. For example, steel-wood composite beams using C-shaped cold-formed thin-walled steel can have a bending ultimate bearing capacity that is more than 30% higher than that of ordinary solid glued laminated timber beams. Compared with ordinary timber beams, steel-wood structural beams have a more complete deformation development process when reaching the ultimate bearing capacity, have a stronger deformation capacity before failure, can better absorb energy, and improve the seismic performance of the structure. The components of steel-wood structural beams can be prefabricated in the factory and assembled on site, resulting in a short construction cycle and improved construction efficiency.

[0003] In existing steel-wood structural beams, the steel and wood panels are typically connected and fixed with bolts. However, multiple bolts need to be disassembled and reassembled separately, which not only increases construction time but also reduces the stability of the installation due to the lack of limiting mechanisms between steel members in different locations. Utility Model Content

[0004] The purpose of this utility model is to provide a steel-wood structural beam for roofs, in order to solve the problem mentioned in the background art that steel and wood are generally connected and fixed by bolts, but multiple bolts need to be disassembled and installed separately, which not only increases the construction time, but also reduces the stability of installation due to the lack of limiting mechanism between steel in different positions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel-wood structure beam for a roof, comprising a main wooden beam with limiting slots on both sides. A first reinforcing plate is provided on one side of the main wooden beam, and a second reinforcing plate is provided on the other side of the main wooden beam. Limiting blocks are fixedly connected to the side surfaces of the first and second reinforcing plates. Locking grooves are provided on the upper and lower surfaces of the limiting blocks. Installation slots are provided on the upper and lower surfaces of the main wooden beam. Locking blocks are installed on the inner walls of the installation slots. Two positioning plates are provided between the first and second reinforcing plates. First threaded holes are provided on the upper and lower surfaces of the main wooden beam. Second threaded holes are provided on the surface of the positioning plates. Mounting bolts are provided on the surface of the second threaded holes. An insertion limiting mechanism is provided between the first and second reinforcing plates and the positioning plates. The limiting mechanism is achieved by inserting the linkage block of the first reinforcing plate into the linkage groove and simultaneously inserting the lateral block of the positioning plate into the lateral groove.

[0006] Preferably, the limiting slot is rectangular, the first reinforcing plate and the second reinforcing plate are symmetrically arranged, and the height of the first reinforcing plate and the second reinforcing plate is higher than the height of the main wooden beam.

[0007] Using the above technical solution, the rectangular limiting slot can form a precisely matched locking structure with the limiting plug, avoiding shaking during insertion and improving installation positioning accuracy.

[0008] Preferably, the limiting insert and the limiting slot form a snap-fit ​​connection, the locking groove is correspondingly provided with the locking block, the locking block is L-shaped, and one end of the locking block is flush with the surface of the main wooden beam.

[0009] Using the above technical solution, one end of the L-shaped locking block is flush with the surface of the main wooden beam, avoiding interference from the protruding structure with the subsequent installation and fitting of the positioning insert plate, and ensuring the compactness of the overall structure.

[0010] Preferably, the positioning plates are located on the upper and lower surfaces of the main wooden beam, the first threaded hole and the second threaded hole are respectively provided, and the mounting bolts are threadedly connected to the first threaded hole and the second threaded hole respectively.

[0011] By adopting the above technical solution, the positioning plates on the upper and lower surfaces can constrain the bending deformation of the main wooden beams in the vertical direction, resist the vertical shear force generated by the roof load, and improve the bending resistance of the structure.

[0012] Preferably, the insertion limiting mechanism includes a linkage groove, which is formed on the side surface of the positioning plate. A lateral insertion block is fixedly connected to the side surface of the positioning plate, a linkage insertion block is fixedly connected to the side surface of the first reinforcing plate, and a lateral groove is formed on the side surface of the second reinforcing plate.

[0013] By adopting the above technical solution, the mechanism forms a multi-directional limiting between the reinforcing plate and the positioning plate through the mechanical interlocking of the "groove-insert block", which avoids the two from sliding or misaligning relative to each other due to external forces and enhances the overall structure.

[0014] Preferably, both the linkage groove and the lateral insert are elongated designs, and the two linkage inserts are located on the upper and lower end side surfaces of the first reinforcing plate, with the linkage inserts corresponding to the linkage groove.

[0015] By adopting the above technical solution, the elongated design increases the contact area between the groove and the insert, disperses local stress, avoids structural wear or breakage caused by point contact, and extends service life.

[0016] Preferably, the lateral grooves are correspondingly provided with the lateral inserts, and the two lateral grooves are distributed on the upper and lower end side surfaces of the second reinforcing plate, and the inner side surface of the positioning insert is in contact with the surface of the locking block.

[0017] By adopting the above technical solution, the corresponding design of the lateral groove and the insert block enables the second reinforcing plate to form a stable connection with the positioning insert plate, which is symmetrical with the limiting structure of the first reinforcing plate, further improving the symmetry and stability of the overall structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the steel-wood structural beam used for the roof: 1. The steel-wood structure beam improves overall stability through multiple limiting and connection structures. The interlocking connection between the main wooden beam and the reinforcing plate, the fixing effect of the locking block, and the bolt connection of the positioning insert plate form multi-directional force constraint, effectively dispersing the roof load and reducing stress concentration in individual components. 2. Construction efficiency is significantly improved. The precise engagement of the limit slot and the plug enables rapid positioning, reduces the number of bolts used, simplifies the disassembly and assembly process, and the mechanical engagement of the plug-in limit mechanism does not require additional tools for fixation, thus shortening on-site installation time. 3. The structure is more coordinated. The combination of steel reinforcement plates and wooden main body gives full play to the advantages of high strength of steel and environmental protection of wood. The symmetrical design and multi-component linkage ensure uniform stress. At the load limit, it can absorb energy through full deformation and improve the seismic performance of the roof.

[0023] Limiting blocks 5 are fixedly connected to the side surfaces of the first reinforcing plate 3 and the second reinforcing plate 4. Locking grooves 6 are provided on the upper and lower surfaces of the limiting blocks 5. Mounting slots 7 are provided on the upper and lower surfaces of the main wooden beam 1.

The locking grooves 6 on the upper and lower surfaces of the limiting blocks 5 are engaged with the L-shaped locking blocks 8 in the upper and lower mounting slots 7 of the main wooden beam 1, further restricting the displacement of the reinforcing plates and preventing loosening.

[0024] The second threaded hole 11 is provided with a mounting bolt 12. The insertion limiting mechanism includes a linkage groove 13, which is opened on the side surface of the positioning plate 9.

[0025] A plug-in limiting mechanism is provided between the first reinforcing plate 3, the second reinforcing plate 4, and the positioning insert plate 9.
