[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] Embodiment 1: This embodiment aims to provide an improved building structure connection device, the core principle of which is to use the bolts in the semi-rigid connection assembly to cooperate with the elliptical holes to achieve the adjustability and stability of the connection between the wall panel and the beam. Through this technical solution, the problems of excessive connection rigidity, lack of adjustment function and poor adaptability mentioned in the background technology are effectively solved, and the safety and stability of the building structure connection device are improved.

[0030] The building structure connection device in this embodiment mainly includes a wall panel 100 , a beam 200 and a semi-rigid connection assembly 300 .

[0031] Wall Panel 100: The wall panel 100 is a rectangular flat plate structure, and is made of high-strength steel or concrete or other building materials.

[0032] A connection hole 340 is reserved on the wall panel 100 . The connection hole 340 is elliptical and is used to cooperate with the bolt 330 in the semi-rigid connection assembly 300 .

[0033] Beam 200: The beam 200 is a long strip structure, and is also made of high-strength steel or concrete or other building materials.

[0034] The beam 200 is also provided with an elliptical hole corresponding to the connection hole 340 on the wall panel 100 for connection with the bolt 330 .

[0035] Semi-rigid connection assembly 300: The semi-rigid connection assembly 300 includes a wall panel connection portion 310 , a beam connection portion 320 and a bolt 330 .

[0036] Wall panel connection portion 310 : corresponds to the connection hole 340 on the wall panel 100 , and is used to fix one end of the bolt 330 .

[0037] Beam body connection portion 320 : corresponds to the elliptical hole on the beam 200 and is used to fix the other end of the bolt 330 .

[0038] Bolt 330: Passes through the elliptical holes on the wall panel 100 and the beam 200, and a semi-rigid connection between the wall panel 100 and the beam 200 is achieved by tightening the bolt 330. Since the connection hole 340 is elliptical, the bolt 330 can be fine-tuned within a certain range to adapt to stress and deformation in different directions.

[0039] Connection hole 340: The oval design allows the bolt 330 to have a certain range of motion during connection, thereby achieving the semi-rigid characteristics of the connection device. This design enables the connection device to disperse stress through fine adjustment of the bolt 330 when subjected to external loads, thereby avoiding damage caused by stress concentration.

[0040] Step 1: Align the wall panel 100 and the beam 200 according to a predetermined position, ensuring that the connection hole 340 corresponds to the elliptical hole on the beam 200 .

[0041] Step 2: Pass the bolt 330 through the holes on the wallboard 100 and the beam 200 and tighten them preliminarily. At this time, since the connection hole 340 is oval, the bolt 330 can be fine-tuned in the hole to adapt to the slight deviation between the wallboard 100 and the beam 200.

[0042] Step 3: Further tighten the bolts 330 as needed to form a firm semi-rigid connection between the wall panel 100 and the beam 200. Due to the cooperation between the bolts 330 and the elliptical holes, the connection device can adapt to the changes in external loads to a certain extent and maintain the stability and safety of the connection.

[0043] This embodiment adopts the design of matching the bolt 330 with the elliptical hole in the semi-rigid connection assembly 300, which effectively solves the problems mentioned in the background art, such as excessive connection rigidity, lack of adjustment function and poor adaptability. Specifically, it is as follows: Improved connection stability: Due to the cooperation between the bolt 330 and the elliptical hole, the connection device can adapt to changes in external loads to a certain extent, avoiding damage caused by stress concentration.

[0044] Enhanced adjustment function: By adjusting the tightening degree of the bolt 330, the stress of the connecting device can be adjusted, thereby improving the adaptability and flexibility of the connecting device.

[0045] Reduced maintenance costs: Since the connection device has good stability and adjustment function, the repair and replacement costs caused by damage to the connection parts are reduced.

[0046] For example, under extreme weather conditions such as earthquakes, the building structure connection device in this embodiment can effectively disperse the stress generated by the earthquake through the cooperation between the bolt 330 and the elliptical hole, thereby maintaining the stability and safety of the building structure. Compared with traditional rigid connection devices, the connection device in this embodiment shows stronger adaptability and stability when dealing with external loads.

[0047] Embodiment 2: This embodiment aims to provide an innovative building structure connection device, the core of which is to use an adjustable connection component to achieve the height adjustability and stability of the connection between the wall panel and the beam. By introducing components such as a pull ring, a pull rope, a threaded head, a contact head and a threaded barrel, the device of this embodiment can flexibly cope with various loads and deformation conditions in the building structure, effectively solving the problems of excessive connection rigidity, lack of adjustment function and poor adaptability mentioned in the background technology.

The diameter and thickness of the pull ring are designed according to the diameter of the pull rope and the required tension to ensure a firm and reliable connection.

[0050] Drawstring 420: The drawstring is made of high-strength fiber material with good flexibility and wear resistance. One end of the drawstring is connected to the pull ring 410, and the other end passes through the inside of the threaded barrel 450 and is connected to the threaded head 430. The length of the drawstring can be adjusted according to actual needs.

[0051] Threaded head 430: The threaded head is a cylindrical structure with an external thread at one end, which is used to match the internal thread of the threaded barrel 450 to achieve a threaded connection.

[0056] Step 3: Rotate the thread head 430 to move it upward or downward along the internal thread of the threaded barrel 450, thereby adjusting the resistance between the abutment head 440 and the wallboard or beam. By adjusting the resistance, the height and stability of the connection device can be adjusted.

[0057] The device of this embodiment achieves the height adjustability and stability of the connection between the wall panel and the beam by introducing an adjustable connection component. Compared with the reference document in the background technology, the device of this embodiment has the following advantages: Height adjustability: By adjusting the length of the pull rope and the position of the thread head in the thread barrel, the height of the connection device can be flexibly adjusted to meet the needs of different building structures.

[0058] Enhanced stability: The contact head adopts a hemispherical structure and high-strength rubber or elastic plastic material, which can effectively buffer and disperse the stress at the connection and improve the stability and safety of the connection.

[0059] Improved adaptability: The device of this embodiment can flexibly cope with various loads and deformation conditions in the building structure, thereby improving the adaptability and flexibility of the connection.

[0060] For example, in high-rise buildings, due to wind loads and earthquake loads, the building structure often undergoes large deformation. By using the device of this embodiment, the height and stability of the connection device can be adjusted according to actual conditions, effectively reducing the risk of connection damage caused by deformation and improving the overall safety and stability of the building structure.

[0061] Embodiment 3: This embodiment aims to provide an enhanced building structure connection auxiliary device, which further optimizes and enhances the stability and adaptability of the building structure connection by introducing components such as steel pipes, sliders, support rods, hemispheres, and contact rings.

Its shape is a long straight tube, and the length can be customized according to specific needs, usually ranging from 1000mm to 3000mm. The outer diameter and wall thickness of the steel pipe are also precisely designed according to the load-bearing requirements to ensure sufficient structural strength.

[0064] Slider 431: Slider 431 is arranged inside steel pipe 421 and can slide freely along the axial direction of the steel pipe. The slider is made of wear-resistant material, has a low friction coefficient and good sliding performance. The slider is in the shape of a rectangular parallelepiped, and its size is slightly smaller than the inner diameter of the steel pipe to ensure smooth sliding while maintaining a certain structural stability.

[0065] Support rod 432: One end of support rod 432 is fixedly connected to slider 431, and the other end is connected to hemisphere 433. The support rod is made of high-strength alloy material and has excellent bending strength and shear strength. The length and diameter of the support rod are designed according to the connection requirements to ensure sufficient support force and stability.

The hemisphere is made of wear-resistant material, and the surface is specially treated to increase friction and ensure close fit with the abutment ring or other connection parts.

[0067] The contact ring 441 is arranged at one or both ends of the steel pipe 421 to contact the hemisphere 433 or other connecting parts. The contact ring is made of high-strength rubber or elastic material, and has excellent elasticity and wear resistance. The inner diameter of the contact ring matches the outer diameter of the steel pipe, and the outer diameter is slightly larger than the diameter of the hemisphere 433 to ensure tight contact and stable connection.

[0068] Step 1: According to the specific requirements of the building structure connection, select the appropriate length and diameter of the steel pipe 421, as well as the specifications of the slider 431, the support rod 432 and the hemisphere 433.

[0069] Step 2: Install the slider 431 inside the steel pipe 421 and adjust its position to the required height. Then, one end of the support rod 432 is fixedly connected to the slider 431 and the other end is connected to the hemisphere 433.

[0070] Step 3: Install the abutment ring 441 on one or both ends of the steel pipe 421 to ensure that it can tightly abut against the hemisphere 433 or other connecting parts.

[0071] Step 4: Connect the device to other building structure connection parts, and adjust the position of the slider 431 in the steel pipe 421 to achieve precise adjustment of the connection height. At the same time, the tight contact between the hemisphere 433 and the contact ring 441 ensures the stability and safety of the connection.

[0072] By introducing components such as steel pipe 421, slider 431, support rod 432, hemisphere 433 and abutment ring 441, this embodiment effectively solves the problems of unstable connection and inconvenient adjustment of the building structure in the background technology. The device not only improves the bearing capacity and adjustment flexibility of the connecting parts, but also enhances the overall stability and safety of the building structure. For example, in complex building structures such as high-rise buildings or large bridges, the device can ensure the stability and durability of the connection parts and effectively avoid the occurrence of connection failure or safety accidents. At the same time, the device also has the advantages of simple structure, easy installation, low maintenance cost, etc., and has high practical value and promotion prospects.
