Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a fixed connection structure for steel seismic isolation bearings. Background Technology

[0002] Because steel-concrete composite columns and beams (reinforced concrete structures) are equipped with steel frames, the mutual restraint between the steel frames and high-strength concrete allows the reinforced concrete structure to more effectively utilize the advantages of both steel and concrete. At the same time, it overcomes the disadvantage of steel structures being prone to local buckling, increases the ductility of the structure and components, and improves the brittle characteristics that are unfavorable to seismic resistance caused by the poor ductility of high-strength concrete itself.

[0003] Steel-concrete composite structures use less steel, have a more reasonable stress distribution, high construction efficiency, and good seismic performance. However, their construction process is complex, the reinforcement density at column-beam joints is high, making it difficult to pour concrete, which can easily lead to early defects in the concrete. In addition, the construction cost is relatively high, and the overall construction complexity is high.

[0004] Therefore, it is necessary to invent a fixed connection structure for steel seismic isolation bearings to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fixed connection structure for steel seismic isolation bearings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed connection structure for a steel seismic isolation bearing, comprising a bearing body, a base threadedly mounted on the top of the bearing body, a limiting plate fixedly connected to the top of the base, multiple reinforcing ribs equidistantly arranged and fixedly mounted on the top of the limiting plate, multiple connecting components for improving strength provided on the outer peripheral surface of the reinforcing ribs, circular holes equidistantly opened on the outer peripheral surface of the reinforcing ribs, each connecting component including a parallel rib that movably penetrates through the circular hole, screws fixedly connected to both ends of the parallel ribs, nuts threadedly connected to the two screws, multiple connecting plates engaging with the outer peripheral surface of the parallel ribs, and slots equidistantly opened at the bottom of the connecting plates engaging with the parallel ribs.

[0007] Preferably, the top of the limiting plate is symmetrically provided with molding components for wrapping the base, and the two molding components include baffles that are slidably connected to the top of the limiting plate. The two baffles are fixedly installed with first limiting blocks in the middle of their outer sides. The two first limiting blocks are engaged with locking blocks. Limiting posts are symmetrically fixedly installed on both sides of the top of the two baffles.

[0008] Preferably, the bottom of the baffle has symmetrically provided limit holes corresponding to the positions of the limit posts.

[0009] Preferably, the limiting plate is composed of two rectangular blocks with different diameters, and the diameter of the baffle is the same as the diameter of the upper part of the blocks on the limiting plate.

[0010] Preferably, the tops of both baffles abut against a top plate, and the bottom sides of the two top plates are symmetrically provided with sliding grooves that are slidably connected to the limiting posts. The diameter of the limiting posts is the same as the width of the sliding grooves.

[0011] Preferably, a second limiting block is symmetrically fixedly connected to both ends of the two top plates, the second limiting block is engaged with the locking block, and a pad is installed on the top of the top plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The molds for beams and columns are assembled using spliced ​​baffles, thus reserving reasonable space for concrete pouring and avoiding pouring difficulties caused by limited space. At the same time, the connecting components connect the reinforcing bars into a whole, forming a regular layout, reducing the obstruction of concrete flow by the reinforcing bars, allowing the concrete to fill each part more smoothly, greatly reducing the probability of early concrete defects, effectively improving construction quality, and ensuring that the advantages of steel-concrete composites in terms of reasonable stress and good seismic performance are fully utilized. The baffles can be demolded by rotating the rotating head, which improves construction efficiency compared to the traditional complicated mold dismantling method. Attached Figure Description

[0020] 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.

[0021] This utility model provides, for example Figures 1-5 The steel seismic isolation bearing fixed connection structure shown includes a bearing body 1, a base 2 threadedly installed on the top of the bearing body 1, a limiting plate 3 fixedly connected to the top of the base 2, a plurality of reinforcing ribs 4 equidistantly arranged and fixedly installed on the top of the limiting plate 3, a plurality of connecting components 5 for improving strength are provided on the outer peripheral surface of the reinforcing ribs 4, and circular holes 401 are equidistantly opened on the outer peripheral surface of the reinforcing ribs 4. The connecting components 5 include parallel ribs 501 that movably pass through the circular holes 401, and screws 502 are fixedly connected to both ends of the parallel ribs 501. Nuts 503 are threadedly connected to the two screws 502, and a plurality of connecting plates 504 are engaged and connected to the outer peripheral surface of the parallel ribs 501. The bottom of the connecting plates 504 is provided with slots 5040 equidistantly opened to engage and connect with the parallel ribs 501.

[0022] The support body 1 serves as the basic support component of the entire device, providing a stable installation foundation for the subsequent structure. The base 2 is connected to the support body 1 by threads, facilitating installation and disassembly. It also serves as a transition and load-bearing element for the upper structure. The limiting plate 3 can limit the position of the components above the base 2 to prevent them from shifting. The reinforcing rib 4 can enhance the structural strength of the top of the limiting plate 3. In the connecting assembly 5, the parallel rib 501 passes through the round hole 401 of the reinforcing rib 4 and is fixed by the screw 502 and nut 503. Multiple connecting plates 504 are engaged on the parallel rib 501, which can connect multiple reinforcing ribs 4 into a whole, further improving the structural strength and stability of the entire device. The overall structure is regular, which facilitates the subsequent concrete filling.

[0023] The top of the limiting plate 3 is symmetrically equipped with two molding components 6 for wrapping the base 2. Each molding component 6 includes a baffle 601 slidably connected to the top of the limiting plate 3. A first limiting block 602 is fixedly installed in the middle of the outer sides of both ends of the two baffles 601. The two first limiting blocks 602 are engaged with a locking block 7. Limiting posts 603 are symmetrically fixedly installed on both sides of the top of the two baffles 601. The molding components 6 form a mold space above the base 2, facilitating casting and other operations. The baffles 601 are slidably connected to the limiting plate 3, allowing for easy adjustment of position and assembly as needed. The first limiting blocks 602 and the locking blocks 7 cooperate to position and fix the two baffles 601, ensuring the structural stability of the molding components 6. The limiting posts 603 provide guidance and limitation during assembly, ensuring accurate component installation.

[0024] The inner sides of the two baffles 601 are provided with grooves, and extrusion blocks 604 are movably fitted in the grooves. Connecting rods 605 that movably pass through the baffles 601 are symmetrically fixed to one side of the two extrusion blocks 604. Horizontal plates 606 are fixedly connected to the ends of the two connecting rods 605. Studs 607 are threadedly connected to the middle of the two horizontal plates 606. One end of the two studs 607 is rotatably connected to the baffles 601, and the other end of the two studs 607 is fixedly connected to a rotating head 608. A cross hole 609 is provided on the outer circumferential surface of the rotating head 608. By rotating the rotating head 608, the studs 607 are rotated. The studs 607 are threadedly connected to the horizontal plates 606, and the other end of the studs 607 is rotatably connected to the baffles 601. Under the action of the horizontal plates 606, the movement of the studs 607 will cause the baffles 601 to move on the connecting rods 605, thereby facilitating the demolding of the baffles 601.

[0025] The bottom of the baffle 601 is symmetrically provided with limiting holes 610 corresponding to the position of the limiting post 603. The limiting holes 610 cooperate with the limiting post 603 to enhance the stability of the baffle 601 after assembly, prevent the baffle 601 from shifting during use, and ensure the overall structural accuracy of the mold assembly 6. The limiting plate 3 is made of two rectangular blocks with different diameters. The diameter of the baffle 601 is the same as the diameter of the upper block of the limiting plate 3. The limiting plate 3 uses rectangular blocks with different diameters to form a stepped structure, which provides a stable mounting plane for the baffle 601. The baffle 601 and the upper block of the limiting plate 3 have the same diameter, which facilitates accurate installation and positioning, and ensures the sealing and stability of the mold assembly 6 after installation.

[0026] The tops of both baffles 601 abut against top plates 8. Symmetrical grooves 801, which slide and connect with limiting posts 603, are provided on both sides of the bottom of the two top plates 8. The diameter of the limiting posts 603 is the same as the width of the grooves 801. The top plates 8 abut against the tops of the baffles 601, sealing the upper space of the mold-making assembly 6 to form a complete mold. The sliding connection between the grooves 801 and the limiting posts 603 allows the top plates 8 to be accurately installed on the baffles 601, while also serving as a guide during installation to ensure the accuracy and stability of the top plate 8's installation position. Second limiting blocks 802 are symmetrically fixedly connected to both ends of the two top plates 8. The second limiting blocks 802 engage with engaging blocks 7. A pad 803 is installed on the top of the top plates 8, and the second limiting blocks 802 engage with engaging blocks 7, connecting the two top plates 8 into a single unit, further enhancing the structural strength and stability of the mold-making assembly 6. The pad 803, installed on top of the top plates 8, provides protection for them.

[0027] The working principle of this utility model is as follows: The base 2 is threaded onto the top of the support body 1, achieving a stable connection between the upper structure and the support body 1, while facilitating disassembly and installation. The limiting plate 3 is fixed to the top of the base 2, accurately positioning the components above it and preventing displacement. The reinforcing ribs 4 further enhance the strength of the top of the limiting plate 3. The connecting assembly 5 connects multiple reinforcing ribs 4 into a whole through the connecting ribs 501, screws 502, nuts 503, and connecting plates 504, improving structural strength. The regular layout creates favorable conditions for subsequent concrete filling. During the concrete pouring operation, the mold-making assembly 6 plays a role, and the baffle 601... The first limiting block 602 and the locking block 7 work together to achieve precise positioning and fixation of the two baffles 601, ensuring the stability of the mold assembly 6. The limiting post 603 provides guidance and limitation during the assembly process to ensure installation accuracy. When demolding is required after pouring, the outer surface of the baffle 601 is first tapped to loosen it. Then, the rotating head 608 is rotated to drive the stud 607 to rotate. The stud 607 and the horizontal plate 606 are threaded together, and the stud 607 drives the baffle 601 to move on the connecting rod 605, which facilitates the demolding of the baffle 601.

[0028] The limiting hole 610 cooperates with the limiting post 603 to enhance the stability of the baffle 601 after installation. The special stepped structure of the limiting plate 3 is precisely matched with the baffle 601 to ensure the sealing and stability of the installation. The top plate 8 is slidably connected to the limiting post 603 through the sliding groove 801 and installed on the top of the baffle 601. The second limiting block 802 is engaged with the locking block 7 to connect the two top plates 8 into a whole, enhancing the strength of the molding component 6. The pad plate 803 protects the top plate 8 to prevent it from being damaged by the pouring pressure, thus completing the fixed connection and casting of the steel seismic isolation support.
