Description

Technical Field

[0001] This utility model relates to the field of seismic connection structure technology, specifically an adjustable seismic connection structure for prefabricated steel structures. Background Technology

[0002] Prefabricated steel structure is a new type of construction method. Its core feature is that steel structural components are prefabricated in a factory and then transported to the construction site for assembly and installation. It consists of steel beams, columns, trusses and other components, which are assembled on site using bolts, welding and other methods. It belongs to a type of prefabricated building. After the steel beams and columns are assembled together, seismic connection structures are used to connect the steel beams and columns again. In this way, the seismic connection structure can achieve the coordination of seismic energy absorption and deformation, thereby improving the seismic performance of the building.

[0003] In existing technologies, the dimensions of seismic connection structures in prefabricated steel structures are relatively fixed and not easy to adjust for expansion and contraction. As a result, the connection length of the connection structure is difficult to adjust according to the actual installation of steel beams and columns, resulting in low overall practicality of the connection structure. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable seismic connection structure for prefabricated steel structures, so as to solve the problem of the seismic connection structure being difficult to adjust as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable seismic connection structure for prefabricated steel structures, comprising steel structure columns, steel structure beams, and connecting rods. The steel structure beams are bolted to the outer side of the steel structure columns. A connecting rod is provided between the steel structure columns and the steel structure beams. A sliding groove is provided inside the connecting rod, and a slider is slidably connected inside the groove. One end of the slider is connected to a sliding rod, and two sliding rods are connected together by a seismic spring. A threaded post is threaded inside the sliding rod, and a connecting ring is welded to one end of the threaded post. A T-shaped post is welded to the outer side of the connecting ring, and a rotating block is rotatably connected to the outer side of the T-shaped post. A vertical plate is welded to the surface of the rotating block, and a connecting shaft is welded together between the two vertical plates.

[0006] Preferably, a flipping block is rotatably connected to the outside of the connecting shaft, a fixing plate is welded to one end of the flipping block, and a fixing bolt is threaded into the inside of the fixing plate.

[0007] Preferably, the slide rod and the connecting rod form a sliding structure.

[0008] Preferably, the rotating block and the T-shaped column form a rotating structure.

[0009] Preferably, two sets of fixing plates are arranged symmetrically about the center of the connecting rod.

[0010] Preferably, the threaded post is made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable seismic connection structure for prefabricated steel structures can extend the connection length of the connecting rod by adjusting the position of the threaded column. When the building vibrates, the two sets of sliding rods inside the connecting rod will move closer and further apart, causing the seismic springs between the two sets of sliding rods to compress and stretch. Through elastic deformation, the seismic impact energy is absorbed, reducing the vibration load directly borne by the structure. At the same time, the sliding rod can drive the slider to slide inside the groove, allowing the connecting rod to disperse the vibration energy, thereby reducing the degree of damage caused by the vibration to the building and improving the seismic resistance of the building. By adjusting the connection length of the connecting rod, the connecting rod can be installed at different positions between the steel structure columns and steel structure beams according to the actual situation, improving the practicality of the seismic connection structure.

[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 Figures 1-5 It is understood that this utility model provides a technical solution: an adjustable seismic connection structure for prefabricated steel structures, including a steel structure column 1, a steel structure beam 2, and a connecting rod 3. The steel structure beam 2 is bolted to the outside of the steel structure column 1. A connecting rod 3 is provided between the steel structure column 1 and the steel structure beam 2. A sliding groove 4 is provided inside the connecting rod 3. A slider 5 is slidably connected inside the sliding groove 4. A sliding rod 6 is connected to one end of the slider 5. An anti-seismic spring 7 is connected between the two sliding rods 6. A threaded post 8 is threaded inside the sliding rod 6. A connecting ring 9 is welded to one end of the threaded post 8.

[0020] This adjustable seismic connection structure for prefabricated steel structures has a groove 4 that can limit the sliding range of the slider 5.

[0021] exist Figures 1-5 In the middle: A T-shaped post 10 is welded to the outside of the connecting ring 9. A rotating block 11 is rotatably connected to the outside of the T-shaped post 10. A vertical plate 12 is welded to the surface of the rotating block 11. A connecting shaft 13 is welded between the two vertical plates 12. A flipping block 14 is rotatably connected to the outside of the connecting shaft 13. A fixing plate 15 is welded to one end of the flipping block 14. A fixing bolt 16 is threaded inside the fixing plate 15.

[0022] This adjustable seismic connection structure for prefabricated steel structures allows the flip block 14 to easily connect the fixing plate 15 with the steel structure column 1 and the steel structure beam 2.

[0023] exist Figures 1-5 In the middle: the sliding rod 6 and the connecting rod 3 form a sliding structure, the rotating block 11 and the T-shaped column 10 form a rotating structure, the fixing plate 15 is symmetrically arranged with two sets about the center of the connecting rod 3, the threaded column 8 is made of stainless steel, and the steel structure column 1 and the steel structure beam 2 are provided with threaded holes at the positions where they are connected to the fixing bolt 16.

[0024] This adjustable seismic connection structure for prefabricated steel structures allows the rotating block 11 to rotate and adjust the position of the fixing plate 15 and the fixing bolt 16, facilitating the subsequent installation and fixing of the fixing bolt 16.

[0025] In practice, after the steel structure column 1 and the steel structure beam 2 are assembled together with bolts, the connecting rod 3 needs to be installed. When the connection length of the connecting rod 3 needs to be adjusted, the two sets of connecting rings 9 can be rotated clockwise. When the connecting ring 9 rotates, it can drive the threaded column 8 and the sliding rod 6 to slide threadedly. At this time, the connecting ring 9 can rotate and move away from the end of the sliding rod 6. When the connecting ring 9 rotates to the designated position, the two sets of rotating blocks 11 can be rotated. When the rotating blocks 11 rotate, they can be rotated through the T-shaped column 10. When the rotating blocks 11 rotate, they can drive the vertical plate 12 and the fixing plate 15 to rotate. At this time, the position of the fixing plate 15 can be rotated and adjusted to the corresponding angle. Then, the two sets of fixing plates 15 can be moved closer to the corresponding steel structure column 12. The installation direction of the structural column 1 and the steel structure beam 2 is pulled. When the fixing plate 15 moves, it can drive the flipping block 14 to move. When the flipping block 14 moves, it can be flipped through the connecting shaft 13, so that the fixing plate 15 can be flipped and moved to the corresponding installation position of the steel structure column 1 and the steel structure beam 2. Then tighten the fixing bolt 16 so that the two sets of fixing plates 15 can be connected and fixed with the steel structure column 1 and the steel structure beam 2. At this time, the connecting rod 3 can be installed at an angle between the steel structure column 1 and the steel structure beam 2. By adjusting the position of the threaded column 8, the connection length of the connecting rod 3 can be extended and adjusted. And by rotating the threaded column 8 to the designated position through the rotating block 11, the installation position of the fixing plate 15 will not be affected.

[0026] See Figures 1-5 It is known that when the building vibrates, the steel structure column 1 and the steel structure beam 2 will sway. At this time, the two sets of sliding rods 6 inside the connecting rod 3 will move closer and further away from each other, causing the seismic spring 7 between the two sets of sliding rods 6 to compress and stretch. Through elastic deformation, the seismic impact energy is absorbed, reducing the seismic load directly borne by the structure. At the same time, the sliding rod 6 can drive the slider 5 to slide inside the sliding groove 4. The sliding groove 4 can limit the maximum distance of movement of the slider 5 and the sliding rod 6, so that the connecting rod 3 can disperse the vibration energy, thereby reducing the degree of damage caused by the vibration to the building and improving the seismic resistance of the building. By adjusting the connection length of the connecting rod 3, the connecting rod 3 can be installed at different positions between the steel structure column 1 and the steel structure beam 2 according to the actual situation, improving the practicality of the seismic connection structure.

[0027] In summary, when using this adjustable seismic connection structure for prefabricated steel structures, the two sets of connecting rings 9 can be rotated clockwise. When the connecting rings 9 rotate, they can drive the threaded column 8 and the slide rod 6 to slide threadedly. At this time, the connecting rings 9 can rotate and move away from the end of the slide rod 6. The slide groove 4 can limit the maximum distance of movement of the slider 5 and the slide rod 6, so that the connecting rod 3 can disperse the vibration energy, thereby reducing the degree of damage caused by vibration to the building and improving the seismic resistance of the building. By adjusting the connection length of the connecting rod 3, the connecting rod 3 can be installed at different positions between the steel structure column 1 and the steel structure beam 2 according to the actual situation, improving the practicality of the seismic connection structure.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
