Description

Technical Field

[0001] This utility model relates to the field of prefabricated building structure technology, and more specifically, to a beam-column quick connection structure for low-rise rural residential buildings. Background Technology

[0002] The rapid beam-column connection structure of low-rise rural houses usually adopts prefabricated assembly node design. It achieves efficient assembly through standardized components and mechanical connectors. This structure is widely used in village and town buildings. Its core role is to improve construction efficiency and seismic performance. Prefabricated nodes reduce on-site operation time and shorten the overall construction cycle. At the same time, the rigid connection method can effectively distribute seismic loads, enhance the stability of the frame, and avoid the complex procedures of traditional cast-in-place technology. It is especially suitable for rural areas with limited resources.

[0003] Traditional rigid connection structures have extremely stringent requirements for construction foundation conditions. Not only does the foundation need to be highly flat, but the dimensions of prefabricated components must also be perfectly accurate. However, the construction environment in rural areas is often relatively rough, and the foundation often has local unevenness due to natural settlement or insufficient compaction. In addition, small errors are easily generated during the production and transportation of components. Traditional structures lack effective on-site adjustment and error compensation mechanisms. This "hard-to-hard" connection method cannot absorb the above deviations, which will result in the beam-column joints having initial assembly stress at the time of installation. During use, the continuous small settlement of the foundation or the expansion and contraction caused by temperature changes will further aggravate the secondary stress concentration inside the joints. Over the long term, this stress will not only reduce the uniformity of structural stiffness, but may also cause weld cracking, bolt loosening, or local deformation of components, ultimately affecting the stability and safe life of the overall frame, and even creating potential safety hazards.

[0004] In summary, in order to adapt to the different construction environments in rural areas, it is necessary to address the problems of poor adaptability and difficulty in adjustment of traditional beam-column quick connection structures, which can easily lead to secondary stress at beam-column joints and affect structural safety. The goal is to enable flexible adjustment of beam-column connection structures to effectively compensate for construction errors and uneven foundation settlement. Utility Model Content

[0005] This utility model provides a quick beam-column connection structure for low-rise rural residential buildings. The problem to be solved is that traditional quick beam-column connection structures have poor adaptability and are difficult to adjust, which can easily lead to secondary stress at the beam-column joints and affect structural safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect beam-column structure for low-rise rural residential buildings, comprising a square steel column, with a lower column and an upper column on the square steel column, and several cantilever beams arranged in a circular array fixedly connected to the outside of the square steel column. An I-beam is provided on one side of the cantilever beam, and two symmetrical butt plates are fixedly connected to both ends of the I-beam. Several upper through holes are opened in the vertical direction of the butt plates, and several lower through holes are opened in the horizontal direction of the butt plates. Reinforcing ribs are provided on the butt plates, and several vertical screws are fixedly connected to the reinforcing ribs. The vertical screws match the upper through holes. A connecting plate is provided between two adjacent butt plates, and several horizontal screws are fixedly connected to the connecting plate. The horizontal screws match the lower through holes.

[0007] In a preferred embodiment, a column is provided below the lower column, and a connecting bolt is used to fix the column and the square steel column together.

[0008] In a preferred embodiment, the outside of the column is provided with a plurality of rotating supports arranged in a circular array, and the rotating supports and the column are fixedly connected by connecting bolts.

[0009] In a preferred embodiment, a bracket is rotatably connected to one end of a rotating support, and a rotating sleeve is rotatably connected to the other end of the bracket.

[0010] In a preferred embodiment, a knob is fixedly connected to the rotating sleeve, and a threaded rod is threadedly connected to the rotating sleeve.

[0011] In a preferred embodiment, a second rotating support is fixedly connected to the end of the threaded rod away from the first rotating support, and a connecting spring is fixedly connected to the end of the second rotating support.

[0012] In a preferred embodiment, the bottom of the I-beam is provided with a rotating support three, and a connecting bolt three is fixedly connected between the rotating support three and the I-beam. The other end of the rotating support three is fixedly connected to the connecting spring.

[0013] In a preferred embodiment, two symmetrical positioning pins are fixedly connected to the bracket, and friction locking blocks are rotatably connected to the positioning pins. The friction locking blocks are movably connected to the rotating sleeve, and a compression spring is fixedly connected between the two friction locking blocks.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model, through a spiral adjustment mechanism consisting of a knob, a rotating sleeve, and a threaded rod, and a flexible buffer system consisting of a connecting spring and multiple rotating supports, allows for easy fine-tuning of the spacing and angle of beam-column joints during construction. This effectively compensates for construction errors and uneven foundation settlement, ensuring the accuracy of structural positioning. At the same time, the connecting spring effectively absorbs and dissipates seismic energy, avoids stress concentration, reduces structural deformation, and significantly improves the seismic safety performance of the residence.

[0015] 2. This utility model provides pre-tightening force through a compression spring, which makes the friction lock block tightly hold the rotating sleeve. This self-locking device effectively prevents the threaded rod from loosening under long-term vibration environment, ensuring the long-term stability of the node connection. At the same time, it is easy to operate. When adjustment is needed, it can be unlocked with a single press and automatically locked after being released. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 6 A quick-connection beam-column structure for low-rise rural residential buildings includes a square steel column 1, with a lower column 101 and an upper column 102 on the square steel column 1. Several cantilever beams 2 arranged in a circular array are fixedly connected to the outside of the square steel column 1. An I-beam 3 is provided on one side of the cantilever beam 2. Two symmetrical butt plates 4 are fixedly connected to both ends of the I-beam 3. Several upper through holes 401 are opened in the vertical direction of the butt plates 4, and several lower through holes 402 are opened in the horizontal direction of the butt plates 4. Reinforcing ribs 6 are provided on the butt plates 4, and several vertical screws 5 are fixedly connected to the reinforcing ribs 6. The vertical screws 5 match the upper through holes 401. A connecting plate 8 is provided between two adjacent butt plates 4. Several horizontal screws 7 are fixedly connected to the connecting plate 8, and the horizontal screws 7 match the lower through holes 402.

[0025] It should be noted that the vertical screw 5, in conjunction with the upper through hole 401, is used to achieve rapid vertical positioning and fixation of the I-beam 3 and the cantilever beam 2. The horizontal screw 7, in conjunction with the lower through hole 402, achieves horizontal connection between adjacent I-beams 3 through the connecting plate 8, enhancing the overall stability of the frame. The reinforcing rib 6 further improves the bending stiffness of the butt plate 4, preventing deformation under stress.

[0026] Refer to the instruction manual appendix Figure 1 A column 9 is installed below the lower column 101, and a connecting bolt 10 is fixedly connected between the column 9 and the square steel column 1.

[0027] It should be noted that column 9, as the bottom support component, is detachably connected to square steel column 1 via connecting bolt 10, which facilitates on-site adjustment of column height and horizontal position to adapt to different foundation conditions, while providing a stable foundation for the superstructure.

[0028] Refer to the instruction manual appendix Figure 4 The column 9 has several rotating supports 11 arranged in a circular array on its exterior. The rotating supports 11 and the column 9 are fixedly connected by connecting bolts 12.

[0029] It should be noted that the rotating support 11 is arranged in a circular array, which can evenly transmit the lateral force on the node of column 9.

[0030] Refer to the instruction manual appendix Figure 5One end of the bracket 13 is rotatably connected to the rotating support 11, and the other end of the bracket 13 is rotatably connected to the rotating sleeve 14.

[0031] It should be noted that the bracket 13 can rotate around the rotating support 11 to adapt to changes in the beam and column installation angle, and the bracket 13 is a rectangular frame, which will not cause motion interference to the movement of subsequent parts.

[0032] Refer to the instruction manual appendix Figure 5 A knob 15 is fixedly connected to the rotating sleeve 14, and a threaded rod 16 is threadedly connected to the rotating sleeve 14.

[0033] It should be noted that rotating the knob 15 drives the rotating sleeve 14 to rotate, which in turn pushes the threaded rod 16 to move axially, thereby achieving precise adjustment of the beam-column node spacing. The rotating sleeve 14 has a threaded hole inside, the size of which is adapted to the threaded rod 16, to achieve stable power transmission.

[0034] Refer to the instruction manual appendix Figure 5 One end of the threaded rod 16 away from the first rotating support 11 is fixedly connected to the second rotating support 17, and one end of the connecting spring 18 is fixedly connected to the second rotating support 17.

[0035] It should be noted that the connecting spring 18 provides elastic buffering when the beam and column are subjected to dynamic loads (such as wind or seismic forces), and absorbs some of the energy by rotating the support 17, thereby reducing stress concentration caused by rigid connection.

[0036] Another embodiment based on the connecting spring 18: the single connecting spring 18 is replaced with a double-layer spring assembly with inner and outer layers. The inner spring has a larger stiffness and the outer spring has a smaller stiffness. Under small loads, only the outer spring works to provide flexible buffering. Under large loads, the two springs work together to avoid excessive deformation, significantly improve the adaptability of the node under different seismic magnitudes, and extend the structural life.

[0037] Refer to the instruction manual appendix Figure 4 The bottom of the I-beam 3 is provided with a rotating support 319. The rotating support 319 and the I-beam 3 are fixedly connected by a connecting bolt 320. The rotating support 319 and the other end of the connecting spring 18 are fixedly connected.

[0038] It should be noted that the rotating support 319 and the connecting spring 18 form a flexible support system, which not only ensures the vertical bearing capacity of the I-beam 3, but also allows the beam to undergo limited displacement when the temperature changes or there is slight settlement, thus avoiding structural cracking.

[0039] Refer to the instruction manual appendix Figure 6Two symmetrical positioning pins 21 are fixedly connected to the bracket 13. Friction locking blocks 22 are rotatably connected to the positioning pins 21. The friction locking blocks 22 are movably connected to the rotating sleeve 14. A compression spring 23 is fixedly connected between the two friction locking blocks 22.

[0040] It should be noted that the friction locking block 22, under the action of the compression spring 23, is tightly attached to the outer wall of the rotating sleeve 14, forming a self-locking mechanism to prevent the threaded rod 16 from loosening unexpectedly under vibration. The positioning pin 21 ensures that the locking block can only rotate within the design range, ensuring the reliability of the locking. When it is necessary to adjust the length of the threaded rod 16, the operator applies pressure to the end of the two friction locking blocks 22 away from the rotating sleeve 14 to overcome the elastic force between the compression springs 23, so that the friction locking blocks 22 are away from the rotating sleeve 14 and loosen their fixation to the rotating sleeve 14. Then the rotating sleeve 14 can be rotated to adjust the length of the threaded rod 16.

[0041] Another embodiment based on the friction lock block 22: the method of rotating the friction lock block 22 on the positioning pin 21 can be improved to a detachable rotating installation structure. Specifically, the friction lock block 22 can be installed on the positioning pin 21 by means of a quick-release pin with a press buckle, and a replaceable wear-resistant liner can be added to the inside of the friction lock block 22 to facilitate later maintenance or liner replacement and reduce the problem of reduced locking force due to wear after long-term use.

[0042] Working principle: The column 9 is connected to the lower column 101 via connecting bolt 10, forming the bottom foundation. During installation, the cantilever beam 2 provides lateral support for the I-beam 3. The upper through holes 401 on the connecting plates 4 at both ends of the I-beam 3 engage with the vertical screws 5 welded to the reinforcing ribs 6, enabling rapid vertical positioning and fixation of the I-beam 3 and the cantilever beam 2. Simultaneously, the horizontal connection between adjacent I-beams 3 is achieved through the connecting plate 8. The transverse screws 7 on the connecting plate 8 are inserted into the lower through holes 402 of the connecting plate 4 and tightened, thus forming a stable horizontal connection. For fine-tuning and buffering, the rotating support 11 is fixed to the column 9 via connecting bolt 2 12. The operator rotates the knob 15 on the rotating sleeve 14, driving the rotating sleeve 14 to rotate. The internal thread of the rotating sleeve 14 engages with the threaded rod 16, thereby... The rotational motion is converted into the linear motion of the threaded rod 16, thereby precisely adjusting the support length. The rotating support 17 at the end of the threaded rod 16 is connected to one end of the connecting spring 18, and the other end of the connecting spring 18 is connected to the bottom of the I-beam 3 through the rotating support 19 and the connecting bolt 20. When encountering dynamic loads, the connecting spring 18 can effectively absorb energy and provide buffering. To prevent the adjusted length from changing due to vibration, the compression spring 23 provides elasticity, so that the two friction locking blocks 22 always hold the outer wall of the rotating sleeve 14, generating friction to achieve self-locking. When readjustment is required, simply press the ends of the two friction locking blocks 22 to overcome the elasticity of the compression spring 23 and separate it from the rotating sleeve 14 to release the lock. Then, rotate the knob 15 to adjust. After releasing, the locking state is automatically restored.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
