Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an adjustable beam-column connection structure for buildings. Background Technology

[0002] In the field of building engineering, beam-column connections are key nodes in the structural load-bearing structure of a building, and their performance directly affects the overall stability and safety of the building. With the diversification of building functions and the increasing complexity of structural forms, higher requirements are placed on the adaptability and flexibility of beam-column connections, especially in scenarios such as construction in complex terrain, design of irregular-shaped buildings, and renovation of existing buildings, where the limitations of traditional beam-column connections are becoming increasingly apparent.

[0003] Currently, common methods for connecting building beams and columns mainly employ welding, bolting, or mortise and tenon joints (for timber structures). Welding connections achieve beam-column fixation through high-temperature fusion, relying on the weld to transfer loads; bolting connections use high-strength bolts to tightly splice beam-column components, relying on the friction generated by the bolt preload to resist external forces; mortise and tenon joints achieve a stable connection through the nesting of concave and convex structures between components. These traditional connection methods require strict adherence to design angles and positions during construction, and the angles are difficult to adjust after connection.

[0004] However, the fixed angle of traditional beam-column connection structures leads to significant shortcomings when facing complex working conditions. For example, in the construction of irregularly shaped buildings, the required beam-column inclination angles are difficult to achieve precisely using traditional fixed connection methods; when renovating existing buildings, beam-column angles need to be adjusted due to deformation of the original structure or new functional requirements, but traditional connection methods are difficult to meet these needs, greatly limiting the adaptability of the building structure and the flexibility of construction, and increasing construction difficulty and cost. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an adjustable beam-column connection structure for buildings, which aims to improve the problem that the fixed angle of traditional beam-column connection makes it difficult to adapt to complex working conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable beam-column connection structure for buildings, including a beam-column, an angle adjustment component is provided above the beam-column, and a connection component is provided on the outer wall of the beam-column;

[0007] The angle adjustment assembly includes a semi-worm gear, which is disposed on the inner wall of beam-column one. A connecting shaft is rotatably connected to the lower side of the inner wall of beam-column one. A handwheel is fixedly connected to one end of the connecting shaft, and a worm is fixedly connected to the other end of the connecting shaft. The tooth end of the worm meshes with the tooth end of the semi-worm gear. A semi-arc plate is fixedly connected to the outer wall of the semi-arc plate. A sliding groove is formed on the inner wall of the semi-arc plate. A support platform is fixedly connected to the lower side of the inner wall of beam-column one. A limit block is fixedly connected to the upper surface of the support platform. A support box is fixedly connected to one end of beam-column one, and beam-column two is fixedly connected to the upper surface of the semi-worm gear.

[0008] Furthermore, the connecting assembly includes a first engaging component, the inner wall of which is slidably connected to the outer wall of the first beam-column, and a second engaging component is slidably connected to the lower side of the outer wall of the first beam-column. A fixing groove is formed between the second engaging component and the first engaging component. Reinforcing blocks are provided on the outer walls of both the first engaging component and the second engaging component. A long fixing bolt is threadedly connected to the upper surface of the first engaging component, and a short fixing bolt is threadedly connected to one side of the outer wall of both the first engaging component and the second engaging component.

[0009] Furthermore, the outer wall of the long fixing bolt is threaded to the inner wall of the second locking member, and the long fixing bolt is used to fix the first locking member and the second locking member.

[0010] Furthermore, the short fixing bolt is threaded on the outer wall of the beam-column one, and the short fixing bolt is used to fix the beam-column one to the locking member one and the locking member two.

[0011] Furthermore, the inner wall of the reinforcing block is attached to the outer wall of the beam and column.

[0012] Furthermore, two limiting blocks and two semi-arc plates are provided.

[0013] Furthermore, the outer wall of the worm is rotatably connected to the inner wall of the support platform, and the worm is used to drive the half-worm wheel to rotate.

[0014] Furthermore, the inner wall of the slide groove is slidably connected to the outer wall of the limiting block, and the slide groove is used to guide the movement of the semi-worm gear.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, rotating the handwheel drives the worm gear to rotate via the connecting shaft. The worm gear meshes with and drives the semi-worm wheel, and the semi-arc plate slides along the limiting block, precisely adjusting the inclination angle of the beam and column. This solves the problem of fixed beam-column connection angles in traditional systems, which are difficult to adapt to complex working conditions. It achieves the goal of flexibly adjusting the beam-column connection angles, effectively improving the adaptability and accuracy of the building structure during construction and use.

[0017] 2. In this utility model, two snap-fit ​​pieces are fitted onto one surface of the beam or column to form a fixing groove. After the parts to be connected are placed in, they are tightened with long and short bolts.

[0025] 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.

[0026] Reference Figures 1-4 An embodiment of this utility model is provided: an adjustable beam-column connection structure for buildings, including a beam-column 1, an angle adjustment component is provided above the beam-column 1, and a connection component is provided on the outer wall of the beam-column 1;

[0027] The angle adjustment assembly includes a semi-worm gear 10, which rotates around beam-column 1 under the drive of worm 14. Its rotation directly changes the tilt angle of beam-column 2, which is fixed to it. The semi-worm gear 10 is located on the inner wall of beam-column 1. A connecting shaft 8 is rotatably connected to the lower side of the inner wall of beam-column 1. A handwheel 7 is fixedly connected to one end of the connecting shaft 8, and worm 14 is fixedly connected to the other end of the connecting shaft 8. The toothed end of worm 14 meshes with the toothed end of semi-worm gear 10. The outer wall of semi-worm gear 10 is fixedly connected to... A semi-arc plate 11 is attached to the outer wall of the semi-worm gear 10 and rotates synchronously with the semi-worm gear 10. The groove 13 on its inner wall cooperates with the limiting block 12 to provide guidance and limit for the rotation of the semi-worm gear 10. The inner wall of the semi-arc plate 11 has a groove 13. A support platform 9 is fixedly connected to the lower side of the inner wall of the beam-column 1. The limiting block 12 is fixedly connected to the upper surface of the support platform 9. A support box 3 is fixedly connected to one end of the beam-column 1. A beam-column 2 is fixedly connected to the upper surface of the semi-worm gear 10.

[0028] Specifically, when it is necessary to adjust the tilt angle of beam-column 2, turn the handwheel 7. The handwheel 7 drives the connecting shaft 8 to rotate, and the worm gear 14 at the end of the connecting shaft 8 rotates accordingly. Since the worm gear 14 meshes with the half worm wheel 10, the rotation of the worm gear 14 drives the half worm wheel 10 to rotate around beam-column 1. When the half worm wheel 10 rotates, its fixed semi-arc plate 11 rotates synchronously. The sliding groove 13 in the semi-arc plate 11 slides along the limiting block 12. The limiting block 12 ensures that the half worm wheel 10 rotates smoothly, and finally realizes the adjustment of the tilt angle of beam-column 2.

[0029] Reference Figures 1-5 The connecting assembly includes a first locking member 4, which, along with a second locking member 5, forms a fixing groove 6 on the surface of the beam-column 1 for clamping the components to be connected. A stable connection with the beam-column 1 and the connecting components is achieved through the tightening action of long fixing bolts 16 and short fixing bolts 17. The inner wall of the first locking member 4 is slidably connected to the outer wall of the beam-column 1. A second locking member 5 is slidably connected to the lower side of the outer wall of the beam-column 1, forming a fixing groove 6 between the second locking member 5 and the first locking member 4. Reinforcing blocks 15 are provided on the outer walls of both the first locking member 4 and the second locking member 5. Long fixing bolts 16 are threaded onto the upper surface of the first locking member 4, and short fixing bolts 17 are threaded onto one side of the outer walls of both the first locking member 4 and the second locking member 5. Bolt 17 and long fixing bolt 16 are threadedly connected to the inner wall of the second locking part 5. The long fixing bolt 16 is used to fix the first locking part 4 and the second locking part 5. The short fixing bolt 17 is threadedly connected to the outer wall of the first beam-column 1. The short fixing bolt 17 is used to fix the first locking part 4 and the second locking part 5 to the first beam-column 1. The inner wall of the reinforcing block 15 is attached to the outer wall of the first beam-column 1. Two limiting blocks 12 are provided. Two semi-arc plates 11 are provided. The outer wall of the worm gear 14 is rotatably connected to the inner wall of the support platform 9. The worm gear 14 is used to drive the semi-worm wheel 10 to rotate. The inner wall of the slide groove 13 is slidably connected to the outer wall of the limiting block 12. The slide groove 13 is used to guide the movement of the semi-worm wheel 10.

[0030] Specifically, the first clamping component 4 and the second clamping component 5 are respectively fitted onto the surface of the beam-column 1 to form a fixing groove 6. The parts to be connected are placed into the fixing groove 6, and the long fixing bolt 16 is threaded through the first clamping component 4 and the second clamping component 5 and tightened to clamp the parts inside the fixing groove 6. Then, the short fixing bolt 17 is threaded through the first clamping component 4 and the second clamping component 5 and threaded to the beam-column 1. At the same time, the reinforcing block 15 is attached to the surface of the beam-column 1 to achieve a reliable connection between the beam-column 1 and other parts.

[0031] Working principle: When an adjustable beam-column connection structure is required, turning the handwheel 7 drives the connecting shaft 8 to rotate. The worm gear 14 at one end of the connecting shaft 8 rotates accordingly. Since the tooth end of the worm gear 14 meshes with the tooth end of the half-worm wheel 10, the rotation of the worm gear 14 will drive the half-worm wheel 10 to rotate around the beam-column 1. When the half-worm wheel 10 rotates, its fixed semi-arc plate 11 rotates synchronously. The sliding groove 13 in the semi-arc plate 11 slides along the limiting block 12. The limiting block 12 plays a guiding and limiting role, ensuring that the half-worm wheel 10 rotates smoothly. Since the upper surface of the half-worm wheel 10 is fixedly connected to the beam-column 2, the tilt angle of the beam-column 2 can be achieved by turning the handwheel 7.

[0032] Furthermore, the first snap-fit ​​component 4 and the second snap-fit ​​component 5 are respectively fitted onto the surface of the beam-column 1, forming a fixing groove 6 between them. The components to be connected are placed in the fixing groove 6. A long fixing bolt 16 is passed through the first snap-fit ​​component 4 and threaded into the inside of the second snap-fit ​​component 5. Tightening the long fixing bolt 16 can fix the first snap-fit ​​component 4 and the second snap-fit ​​component 5, thereby clamping the components in the fixing groove 6. At the same time, a short fixing bolt 17 is passed through the first snap-fit ​​component 4 and the second snap-fit ​​component 5 and threaded into the surface of the beam-column 1, fixing the first snap-fit ​​component 4, the second snap-fit ​​component 5 and the beam-column 1. The reinforcing block 15 fits against the surface of the beam-column 1, further enhancing the connection stability and realizing a reliable connection between the beam-column 1 and other components.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
