Abstract
Description
Technical Field
[0001] This invention relates to the field of building structure technology, specifically to a positioning and fixing device for installing embedded parts of seismic isolation bearings. Background Technology
[0002] Nowadays, seismic isolation design has become an important development trend in structural seismic resistance. As one of the important methods of vibration isolation and energy dissipation design, rubber seismic isolation bearings are gradually changing the traditional design concept of resisting seismic forces by simply increasing the stiffness and strength of buildings.
[0003] Seismic isolation bearing embedded parts / embedded plates are steel plate components installed in the concrete of building foundations or substructures for precise fixing of seismic isolation rubber bearings. They are usually welded with anchor bars to enhance the anchorage with the concrete and provide a connection interface for the upper bearing.
[0004] In existing technologies, before assembling the seismic isolation bearings, the embedded parts are first installed inside the reinforcing cage. The center reference and installation elevation of the reinforcing cage are determined first, and then the embedded plates are assembled and fixed to the reinforcing cage body using embedded bolts. After fixing, concrete is poured, and the overall positioning of the embedded parts is achieved through concrete curing, thus providing a preliminary foundation for the subsequent installation of the seismic isolation bearings. However, because some existing reinforcing cages are manually tied, it is difficult to maintain consistent center references among the cages, and the on-site center alignment of the reinforcing cages is challenging, easily leading to positioning deviations that interfere with subsequent construction procedures. Furthermore, before the embedded plates are formally assembled, the embedded bolts need to be pre-treated by spot welding. If the embedded bolts become misaligned during welding, it may hinder the normal assembly of the embedded plates, reducing the compatibility of the subsequent seismic isolation bearing installation and making it difficult to ensure overall construction quality. Summary of the Invention
[0005] This invention overcomes the shortcomings of the prior art and proposes a positioning and fixing device for installing embedded parts of seismic isolation bearings.
[0006] This invention is achieved through the following technical solution: A positioning and fixing device for installing embedded parts of seismic isolation bearings includes two sets of first mounting blocks, with two sets of second mounting blocks disposed between the two sets of first mounting blocks. Positioning components are provided on the surfaces of both sets of first and second mounting blocks. Each positioning component includes multiple sets of positioning rods. Sliding grooves are formed on the surfaces of both the first and second mounting blocks. The multiple sets of positioning rods are slidably connected to the inner walls of the sliding grooves. A retractable support rod is threaded to the bottom end of two sets of positioning rods. A support block is fixedly connected to the upper surface of one end of each of the first and second mounting blocks.
[0007] Preferably, both sides of the first mounting blocks of both sets are provided with mounting grooves, and both sides of the second mounting blocks are fixedly connected with locking blocks, which are engaged with the inner wall of the mounting grooves.
[0008] Preferably, each of the two sets of first mounting blocks has a plug connected to its surface by a reset spring. The bottom end of the plug extends to the inner wall of the mounting groove. The surface of the locking block has a slot that matches the plug. The bottom end of the plug and the end of the locking block are both provided with matching guide slopes.
[0009] Preferably, each of the multiple sets of positioning rods has a connecting rod threaded onto its surface, and one end of each connecting rod is connected to a mating block.
[0010] Preferably, a fixing block is fixedly connected to the top of the positioning rod, a moving plate is slidably connected to the inner wall of the fixing block, a sliding rod is slidably connected to the surface of the moving plate, a positioning plate is connected to the end of the sliding rod away from the moving plate, and a spring is sleeved on the outer wall of the sliding rod.
[0011] Preferably, a piston rod is slidably connected to the inner wall of the fixed block, and the movable plate is sleeved on the outer wall of the piston rod. A set of the outer walls of the piston rod is threadedly connected to a threaded block, and the threaded block is rotatably connected to the first mounting block.
[0012] Preferably, one end of one group of piston rods is connected to multiple sets of connecting pipes, and the other end of the multiple sets of connecting pipes is connected to the remaining piston rods.
[0013] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention drives the corresponding piston rod to move by rotating the threaded block. The hydraulic medium can be transported to the inner wall of the other piston rods through the connecting pipe, thereby realizing the synchronous linkage of multiple sets of piston rods. This drives multiple sets of moving plates and positioning plates to move synchronously, ensuring the consistency of positioning actions around the perimeter. To a certain extent, this can avoid the alignment error caused by step-by-step adjustment. The springs set between the positioning plate and the moving plate form an elastic adaptive structure, which facilitates the tight fit of multiple sets of positioning plates against the side wall of the embedded plate, realizing the clamping and centering of the embedded plate. This prevents the embedded plate from shifting to a certain extent. After the embedded plate is aligned, it is pre-fixed, which can resist the impact force generated during concrete pouring and vibration to a certain extent, preventing the embedded plate from twisting, floating, or shifting. This provides a reliable benchmark for the subsequent assembly of seismic isolation bearings, effectively avoiding installation deviations of seismic isolation bearings, and thus facilitating the subsequent installation of seismic isolation bearings. 2. This invention allows for quick connection of the first and second mounting blocks through the design of the locking blocks and mounting slots, making the assembly process relatively convenient. The assembled device is placed on the reinforcing cage, and then the connecting rods are rotated to drive the positioning rods to move horizontally synchronously. When one side of multiple positioning rods is in contact with the outer wall of the reinforcing cage, the center point of the reinforcing cage can be determined, facilitating the search for the center point of reinforcing cages of different sizes. The operation is simple and convenient, improving the efficiency of the reinforcing cage benchmark alignment process to a certain extent and laying the foundation for the subsequent installation of embedded plates.

[0016] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.
[0017] Please see Figures 1 to 6This invention provides a positioning and fixing device for installing embedded parts of seismic isolation bearings, comprising two sets of first mounting blocks 1 arranged opposite each other, and two sets of second mounting blocks 2 arranged between the two sets of first mounting blocks 1, which are also arranged opposite each other; each of the surfaces of the first mounting blocks 1 and the second mounting blocks 2 is provided with a positioning component, which includes a positioning rod 41. By setting the positioning rod 41, the first mounting blocks 1 and the second mounting blocks 2 can be clamped onto the outer wall of the top of the reinforcing cage, thereby facilitating the subsequent positioning of the center point of the embedded plate; the surfaces of the first mounting blocks 1 and the second mounting blocks 2 are provided with positioning components. Each surface is provided with a sliding groove, and a positioning rod 41 is slidably connected to the inner wall of each of the four sets of sliding grooves. The positioning rod 41 can be limited by the sliding groove, so that the positioning rod 41 can only move parallel to the inner wall of the sliding groove. The bottom end of the positioning rod 41 connected to the first mounting block 1 is threaded with a telescopic support rod 3. By adjusting the height of the telescopic support rod 3, different situations can be adapted to install the embedded plate. The upper surface of one end of the first mounting block 1 and the second mounting block 2 is fixedly connected with a support block 5. The support block 5 can support the embedded plate, thereby facilitating the subsequent positioning of the embedded plate.
[0018] See Figure 3 and Figure 4 It can be seen that the two sets of first mounting blocks 1 have mounting grooves 11 on both sides of the surface, and the two sides of the second mounting block 2 are fixedly connected with locking blocks 21. The locking blocks 21 are locked into the inner wall of the mounting groove 11. By locking the locking blocks 21 into the inner wall of the mounting groove 11, the first mounting block 1 and the second mounting block 2 can be connected to form a whole, which facilitates the subsequent positioning assistance of the embedded plate.
[0019] See Figure 3 , Figure 4 , Figure 6 It can be seen that both sides of the surface of the two sets of first mounting blocks 1 are connected to the insertion rods 12 by reset springs. With the reset springs, the insertion rods 12 can be reset under their elastic action. The bottom end of the insertion rods 12 extends to the inner wall of the mounting groove 11. The surface of the locking block 21 is provided with a slot that matches the insertion rods 12. When the insertion rods 12 are inserted into the inner wall of the slot on the surface of the locking block 21, the locking block 21 can be limited, integrating the first mounting block 1 and the second mounting block 2 into a whole. The bottom end of the insertion rods 12 and the end of the locking block 21 are provided with matching guide slopes. With the setting of the guide slopes, when the locking block 21 is locked into the inner wall of the mounting groove 11, the insertion rods 12 can be lifted up, so that when the locking block 21 is subsequently docked in place, the insertion rods 12 can be locked into the inner wall of the slot.
[0020] See Figure 3 - Figure 5It can be seen that the surfaces of multiple positioning rods 41 are threaded with connecting rods 43, and one end of the connecting rod 43 is connected to a mating block 431. When the first mounting block 1 is connected to the second mounting block 2, the connecting rods 43 on the two sets of first mounting blocks 1 and the two sets of second mounting blocks 2 are aligned in pairs, and then the mating blocks 431 are engaged, so as to facilitate the rotation of the connecting rods 43 on the first mounting block 1 and the second mounting block 2 respectively, and adjust the position of the positioning rod 41.
[0021] See Figure 4 and Figure 5 It is known that a fixing block 42 is fixedly connected to the top of the positioning rod 41, a moving plate 44 is slidably connected to the inner wall of the fixing block 42, a sliding rod 46 is slidably connected to the surface of the moving plate 44, a positioning plate 45 is connected to the end of the sliding rod 46 away from the moving plate 44, and a spring is sleeved on the outer wall of the sliding rod 46. The positioning plate 45 can be limited by the sliding rod 46, and the positioning plate 45 can be moved by the moving plate 44. When the positioning plate 45 contacts the side wall of the embedded plate, the positioning of the embedded plate can be completed.
[0022] See Figure 4 and Figure 5 It is known that a piston rod 47 is slidably connected to the inner wall of the fixed block 42, and a moving plate 44 is sleeved on the outer wall of the piston rod 47. A set of piston rods 47 are threadedly connected to the outer wall of the outer wall with threaded blocks 471, and the threaded blocks 471 are rotatably connected to the first mounting block 1. By rotating the threaded blocks 471, the piston rod 47 can be moved on the inner wall of the fixed block 42, thereby squeezing the hydraulic medium on the inner wall of the piston rod 47.
[0023] See Figure 1 - Figure 5 It is known that one end of one set of piston rods 47 is connected to multiple sets of connecting pipes 48, and the other end of the multiple sets of connecting pipes 48 is connected to the other piston rods 47. When one set of piston rods 47 moves, the hydraulic medium inside it is squeezed. The hydraulic medium is transmitted to the other piston rods 47 through the connecting pipes 48, which can simultaneously drive multiple sets of moving plates 44 to move at the same time, which is convenient for positioning the embedded plate.
[0024] The working principle of this invention is as follows: Before the formal installation of the seismic isolation bearing, the connecting rods 43 on the two sets of first mounting blocks 1 are aligned so that the mating blocks 431 at the ends of the two sets of connecting rods 43 engage with each other to complete the mating assembly of the connecting rods 43. Then, the locking blocks 21 on the two sets of second mounting blocks 2 are inserted into the inner wall of the mounting grooves 11 opened on both sides of the first mounting block 1. Since the ends of the locking blocks 21 and the ends of the insert rods 12 are provided with guide slopes, and the outer wall of the insert rods 12 is fitted with a return spring, the locking blocks 21 push the insert rods 12 during the insertion into the mounting grooves 11 and cause them to move. At this time, the return spring is compressed synchronously. When the locking blocks 21 are fully embedded in the mounting grooves 11, the return spring releases its elastic potential energy and drives the insert rods 12 to return to their original position, so that the insert rods 12 are inserted into the slots opened on the surface of the locking blocks 21. This completes the overall assembly of the two sets of first mounting blocks 1 and the two sets of second mounting blocks 2, providing an assembly basis for the precise positioning of the subsequent embedded plates.
[0025] After the first mounting block 1 and the second mounting block 2 are installed, the two sets of telescopic support rods 3 are threaded to the bottom of the positioning rods 41 on the first mounting block 1. According to the design installation height of the embedded plate, the telescopic support rods 3 are rotated to adjust the overall support height. After the height adjustment is completed, the center point of the steel cage can be found. When the two sets of first mounting blocks 1 and the two sets of second mounting blocks 2 are assembled into a whole structure, the connecting rods 43 form an integral connection structure through the mating blocks 431. The positioning rods 41 are threaded to the connecting rods 43. Rotating the two sets of connecting rods 43 respectively drives the positioning rods 41 on the corresponding first mounting block 1 and second mounting block 2 to adjust the horizontal displacement. When one side surface of the multiple sets of positioning rods 41 is in contact with the outer wall of the steel cage, the encirclement center of the multiple sets of positioning rods 41 is the center reference position of the steel cage.
[0026] Piston rods 47 are connected to the inner walls of the fixing blocks 42 on both sets of first mounting blocks 1 and two sets of second mounting blocks 2. After the center point of the steel cage is aligned, the embedded plate is placed on the surface of multiple sets of support blocks 5. One side surface of one set of first mounting blocks 1 is rotatably connected to a threaded block 471. The threaded block 471 and the corresponding piston rod 47 form a threaded transmission engagement. By rotating the threaded block 471, the corresponding piston rod 47 can be driven to make horizontal extension and retraction displacement. The piston rod 47 squeezes the hydraulic medium inside it. The hydraulic medium is synchronously transported to the internal cavity of the other sets of piston rods 47 through the connecting pipe 48, thereby driving the four sets of moving plates 44 to move horizontally synchronously, and driving the positioning plates 45 of each set to move synchronously.
[0027] During the positioning and adjustment process, some positioning plates 45 are in contact with the side wall of the embedded plate, while the remaining positioning plates 45 are not in contact with the embedded plate. The threaded block 471 continues to rotate. At this point, the spring between the positioning plate 45 that is in contact with the embedded plate and the corresponding moving plate 44 is compressed until all four sets of positioning plates 45 are tightly in contact with the side wall of the embedded plate, completing the self-adaptive centering positioning of the embedded plate. After positioning, the embedded plate and its supporting embedded components are fixed to the preset installation position of the reinforcing cage, completing the pre-fixing operation of the embedded plate. Subsequently, concrete pouring is carried out in the reinforcing cage construction area. After the concrete cures, the permanent positioning installation of the embedded plate is completed, providing a precise benchmark for the subsequent assembly of the seismic isolation bearings. This can, to a certain extent, avoid installation deviations of the seismic isolation bearings and significantly improve the positioning accuracy of the embedded assembly.
