[0002] A wooden beam is a horizontally placed structural member, mainly used to bear the weight of a floor slab, a roof or other structural members, and transfer it to the columns or walls supporting it. A wooden beam can bear bending, shear and compression forces and is an indispensable load-bearing member in construction. A column, on the other hand, is a vertically placed structural member used to support the beam, the load on the beam and other weights of the building, and transfer them to the foundation or footing. The column plays a very important supporting role in construction. It can bear compression force and is the key to the stability of the whole structure. Wooden beams and columns are usually used in combination to jointly form the frame structure of a building. This structure is called a framed structure. The framed structure has the characteristics of good seismic performance, fast construction speed and strong adaptability, and is widely used in various buildings, including residential buildings, commercial buildings and public facilities.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figures 1-5, the utility model provides a technical solution: a connection structure between a wooden beam and a column, including a square column 1 and a cross beam 5. A fixing rod 11 is connected to the inner wall of the square column 1. Three support rods 10 are connected to the left side surface of the fixing rod 11. One end of each support rod 10 away from the square column 1 penetrates through the inner wall of the square column 1 and extends to the outside of the square column 1. A U-shaped groove 26 is provided at one end of each support rod 10 away from the square column 1. Rotating rods 24 are connected to the inner walls of two of the U-shaped grooves 26. An active rod 25 is hinged to the outer surface of each rotating rod 24. A semi-circular ring 23 is connected to one end of each active rod 25 close to the cross beam 5. A group of fastening plates 17 are connected to the outer surface of each semi-circular ring 23. A fixing nail 18 is jointly connected to the inner walls of each group of fastening plates 17 facing each other. A nut 19 is connected to the outer surface of each fixing nail 18. A support block 14 is connected to the inner wall of one of the U-shaped grooves 26. A U-shaped block 13 is connected to the left side surface of the support block 14. A connecting shaft 20 is connected to the inner wall of the U-shaped block 13.

[0023] Among them, a cover plate 12 is connected to the upper surface of the square column 1. The presence of the cover plate 12 can increase the contact area between the wooden beam and the column, thereby improving the firmness of the connection. This structure can effectively resist the shear force and tensile force between the beam and the column, making the entire structure more stable. A cavity 15 is provided in the inner wall of the square column 1.

[0024] Among them, a protective cover 6 is connected to the left side surface of the square column 1. The presence of the protective cover 6 can provide additional lateral support to prevent the wooden beam from moving or rotating in the horizontal direction, thereby enhancing the stability of the entire structure. A group of connecting pieces 3 are jointly connected to the front and back surfaces of the square column 1 and the protective cover 6.

[0025] Among them, a group of self-tapping screws 4 are connected to the outer surface of each connecting piece 3. The self-tapping screws 4 can provide additional fixing points, making the connection between the connecting piece 3 and the wooden beam and the column more firm, and improving the overall stability of the structure. Two triangular braces 2 are jointly connected to the bottom surface of the protective cover 6 and the left side surface of the square column 1.

[0026] Among them, a connecting block 16 is connected to the inner wall of the protective cover 6. The presence of the connecting block 16 can provide more connection points, making the connection between the wooden beam and the column more firm. This structure can effectively resist the shear force and tensile force between the beam and the column, making the entire structure more stable. A fixing ring 9 is connected to the left side surface of the connecting block 16.

[0027] Among them, two adjusting blocks 7 are connected to the outer surface of the fixing ring 9. An adjusting nail 8 is jointly connected to the inner walls of the two adjusting blocks 7. The design of the adjusting blocks 7 and the adjusting nail 8 allows for fine adjustment of the connection between the wooden beam and the column to ensure the accuracy and levelness of the structure. This is very important for wooden structure buildings because the natural characteristics of wood may cause slight changes in size and shape.

[0028] Wherein, a movable block 21 is hinged to the outer surface of the connecting shaft 20. The design of the movable block 21 allows the wooden beam to have a certain rotational or swinging ability on the connecting shaft 20, so as to adapt to the expansion and contraction of the wood caused by temperature and humidity changes to a certain extent. Two clamping plates 22 are connected to the right side surface of the cross beam 5, and the inner walls of the two clamping plates 22 are connected to the movable block 21.

[0029] Working principle: During use, the square column 1 serves as a vertical support, the triangular brace 2 provides lateral stability, the connecting piece 3 is fixed to the cross beam 5 and the square column 1 by self-tapping screws 4 to provide connection strength. The protective cover 6 is installed on the side surface of the square column 1 to protect the wood and provide an aesthetically pleasing surface. The support rod 10 and the fixed rod 11 cooperate with each other to provide better stability. The cooperation of the rotating rod 24, the movable rod 25 and the U-shaped groove 26 can adjust the size to better adapt to cross beams 5 of different sizes and can also perform fine adjustment, thereby improving the adaptability of the connection structure. The adjusting block 7 and the adjusting screw 8 are used for fine adjustment of the connection to ensure the accuracy and levelness of the structure. Connecting parts such as the fixing ring 9, the fastening plate 17, the fixing screw 18, and the nut 19 are used to tightly fix the cross beam 5 and the square column 1 together. The support rod 10, the fixed rod 11, the U-shaped block 13, and the support block 14 are used to provide additional support or fixing functions.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
