Description

Technical Field

[0001] This utility model relates to the field of beam-column connection reinforcement technology, specifically a glued laminated timber beam-column connection reinforcement structure. Background Technology

[0002] With the rapid development of modern timber-framed buildings, glued laminated timber (GLLT), as a high-performance building material, has attracted widespread attention due to its unique advantages. GLLT is made by gluing small-diameter timber together along the grain, resulting in high strength, uniform structure, and resistance to deformation. Its superior fire resistance and seismic performance effectively reduce the risk of fire and earthquakes. As a renewable resource, GLLT production consumes low energy, undergoes rigorous processing, and exhibits high durability, offering significant environmental advantages throughout the building's lifecycle. Its applications are wide-ranging, not only suitable for residential buildings but also widely used in large-span structures such as stadiums, public buildings, and bridges. It also provides excellent thermal insulation and soundproofing, effectively reducing energy consumption and improving building comfort. Driven by continuous technological innovation and market demand, GLLT's importance in green and low-carbon building is increasingly prominent, demonstrating broad application prospects and providing new ideas and directions for the sustainable development of the construction industry.

[0003] Common metal connectors, such as screws and metal clamps, are easy to install, but under long-term stress, the creep of wood can cause the joints to loosen, reducing the stability and load-bearing capacity of the structure. Utility Model Content

[0004] In view of the technical problems in the prior art, the present invention provides a glued laminated timber beam-column connection reinforcement structure, the purpose of which is to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A glued laminated timber beam-column connection reinforcement structure includes a column and a beam. The top of the column is inserted into the bottom of the beam. At least two vertically arranged reinforcement blocks are arranged in a circular array on the outer wall of the column corresponding to the beam. The bottom of the reinforcement block has an insert that can be inserted into the column on the side facing the column. The beam has a through groove that runs vertically through the insertion block. The top of the reinforcement block extends into the through groove and fits against the side wall of the through groove facing the column. The top of the beam has a stabilizing structure that can be inserted into the through groove to limit the position of the insert in the through groove.

[0007] Preferably, the stabilizing structure includes multiple limiting blocks adapted to the structure inside the through groove. Each of the multiple limiting blocks has a U-shaped groove adapted to the top of the reinforcing block. The limiting blocks and the reinforcing block are fixed in the through groove by steel nails at the location corresponding to the outside of the beam.

[0008] Preferably, the top of the plurality of limiting blocks is provided with a connecting plate for fixing the plurality of limiting blocks together, and the top of the beam body is provided with an installation groove that is adapted to the connecting plate.

[0009] Preferably, the insert is inclined downward toward the beam, and the outer wall of the beam is provided with a slot that matches the insert.

[0010] Preferably, the bottom side of the beam is provided with a support plate on the left and right sides of the column, and the upper side of the support plate abuts against the bottom side of the beam. The side of the reinforcing block facing the support plate has an insertion groove for inserting the support plate. When the reinforcing block is inserted into the groove, the position of the insertion groove corresponds exactly to the support plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model provides a glued laminated timber beam-column connection reinforcement structure. A limiting block, along with steel nails, secures the top of the reinforcement block within a through groove. Simultaneously, the bottom of the reinforcement block features an insert that slopes towards the column. This inclined support more efficiently resists lateral loads, such as wind loads and seismic forces. By changing the direction of force, the load is distributed more evenly throughout the support system, significantly improving the structure's lateral stiffness and overall load-bearing capacity. The through groove also facilitates the insertion of the inclined insert. Furthermore, a support plate at the bottom of the beam, in conjunction with the insertion groove, increases overall support for the beam, enhancing its stability. The overall structure is simple, easy to construct, and exhibits higher stability compared to screws and metal clamps under long-term stress. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-4 This application proposes a glued laminated timber beam-column connection reinforcement structure, including a column 1 and a beam 2. The top of the column 1 is inserted into the bottom of the beam 2, forming a basic connection structure. To enhance the stability and load-bearing capacity of the connection, at least two vertically arranged reinforcement blocks 3 are arranged in a circular array on the outer wall of the column 1 corresponding to the beam 2. The number of reinforcement blocks 3 is adjusted according to the structure of the beam 2 or the actual stress requirements, such as two, three, or four, to ensure uniform stress distribution in the connection. A plug 4 is provided on the bottom side of the reinforcement block 3 facing the column 1, and the plug 4 is inclined downwards towards the beam 2. The tilt angle design can more effectively resist lateral loads, such as wind loads and seismic forces. By changing the direction of force, the load is transferred to the support system more evenly, thereby significantly improving the lateral stiffness of the structure. The outer wall of the beam 2 is provided with a slot 11 that matches the insertion block 4. The shape and size of the slot 11 match the insertion block 4, so that the insertion block 4 can be accurately inserted into the slot 11 and fit tightly against the outer wall of the beam 2. This design not only improves the positioning accuracy of the insertion block 4, but also further enhances the integrity and stability of the connection through the cooperation between the slot 11 and the insertion block 4.

[0020] A through groove 5 is provided at the corresponding insertion block 4 of beam 2, and the size and shape of the through groove 5 are matched with the insertion block 4, so that the top of the reinforcing block 3 can extend into the through groove 5 and fit tightly against the side wall of the through groove 5 facing the column 1. This design not only increases the contact area of ​​the connection, but also further improves the stability of the connection through the cooperation between the insertion block 4 and the through groove 5.

[0021] To further enhance the stability of the connection, see Figure 2-4The top of the beam 2 is equipped with a stabilizing structure, which includes multiple limiting blocks 6 that are adapted to the structure inside the through groove 5. The number and position of the limiting blocks 6 correspond one-to-one with the reinforcing blocks 3. Each limiting block 6 has a U-shaped groove 7 at the top of the corresponding reinforcing block 3. The size and shape of the U-shaped groove 7 match the top of the reinforcing block 3, so that the limiting block 6 can tightly wrap around the top of the reinforcing block 3. By using steel nails 8 to fix the limiting blocks 6 and the reinforcing blocks 3 in the through groove 5 outside the beam 2 (or by using a combination of gluing and steel nails 8, depending on the specific construction), the limiting effect on the insert block 4 is achieved, preventing the reinforcing block 3 from shifting or loosening during the stress process. This fixing method is simple and reliable, and can effectively improve the overall integrity of the connection.

[0022] To further optimize the connection effect of the stable structure, see Figure 2-4 Multiple limiting blocks 6 are topped with connecting plates 9. The connecting plates 9 are fixed together by welding or steel nails 8 to form a whole. The top of the beam 2 has a matching mounting groove 10 corresponding to the connecting plate 9. The size and shape of the mounting groove 10 match the connecting plate 9, so that the connecting plate 9 can be firmly embedded in the mounting groove 10 and tightly connected with the beam 2. This design not only enhances the connection strength between the limiting blocks 6, but also further improves the integrity and stability of the stable structure through the cooperation of the connecting plate 9 and the mounting groove 10, so that it can better resist the action of external loads. At the same time, the structure of the connecting plate 9 can be adjusted according to the actual installation of the beam 2 and the ceiling to make it more suitable for the overall structure.

[0023] To further optimize the connection effect of the stable structure, the bottom side of the beam 2 is provided with a support plate 12 on the left and right sides of the column 1 respectively. The upper side of the support plate 12 abuts against the bottom side of the beam 2. The side of the reinforcing block 3 facing the support plate 12 has an insertion groove 13 for inserting the support plate 12. When the reinforcing block 3 is inserted into the slot 11, the position of the insertion groove 13 corresponds exactly to the support plate 12, thereby increasing the support for the beam 2. At the same time, steel nails can be driven between the connecting plate 9 and the support plate to further stabilize the connecting plate 9 and the support plate 12 and prevent the support plate 12 from shifting.

[0024] As described above, the glued laminated timber beam-column connection reinforcement structure of this utility model can effectively achieve a stable connection between glued laminated timber beams and columns. It has the advantages of simple structure, convenient construction, high lateral stiffness and strong overall load-bearing capacity, and is particularly suitable for beam-column connection reinforcement in glued laminated timber structure buildings.
