Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically relating to the auxiliary structure of seismic isolation bearings for buildings. Background Technology

[0002] In the field of modern construction engineering, earthquake disasters pose a serious threat to the safety of buildings. As a key seismic-resistant device, seismic isolation bearings are widely used in various building structures. Their main function is to be installed at the bottom of the structure to separate the upper structure from the lower structure. Through their own deformation, they consume and buffer the vibration of the lower structure during earthquakes, thereby effectively reducing the seismic reaction force, protecting the upper structure, and weakening the destructive force of earthquakes on buildings.

[0003] The installation accuracy of seismic isolation bearings directly affects the overall seismic performance of the structure. In order to ensure the installation accuracy of seismic isolation bearings, the method of installing positioning embedded plates is often used in construction to control the installation flatness, installation elevation and installation position. If the elevation deviates, the seismic isolation bearing will be subjected to uneven force when bearing vertical loads, which will greatly reduce the seismic isolation effect. In severe cases, it may cause excessive local stress in the bearing and lead to structural instability. Furthermore, inaccurate levelness and center position will prevent the seismic isolation bearing from deforming in the expected direction and displacement during an earthquake, weakening its ability to dissipate seismic energy and making it difficult to effectively protect the superstructure.

[0004] The current traditional method for installing positioning embedded plates involves welding four short steel bars to the four corners of the top surface of the lower support pier's steel cage. The top elevation of these short steel bars is the same as the bottom elevation of the lower embedded steel plate. The top surfaces of the four short steel bars must be cut flat to ensure the levelness of the positioning embedded plate. Then, equally spaced cross lines are marked on the positioning embedded plate. The center line of the cross on the positioning embedded plate is manually aligned with the cross engineering line or infrared line on the pre-installed support pier to ensure the planar position of the embedded plate. However, this method has significant drawbacks: the temporary elevation steel bars are manually welded, and their position cannot be adjusted after being fixed. Elevation and level correction require cutting and re-welding, which is inefficient and can easily damage the structure. The operation of centering the positioning embedded plate is cumbersome, resulting in low construction efficiency. Summary of the Invention

[0005] The purpose of this utility model is to provide an auxiliary structure for seismic isolation bearings in buildings, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The auxiliary structure for seismic isolation bearings in buildings includes a positioning plate and four sets of positioning adjustment components evenly distributed around the perimeter of the positioning plate. The positioning adjustment components include: a clamping member for clamping and fixing to the casting template of the lower support pier; a horizontal adjustment member connected to the clamping member and capable of adjusting the horizontal distance between the side of the positioning plate and the clamping member; and a height adjustment member connected between the positioning plate and the horizontal adjustment member.

[0008] Preferably, the clamping member includes: a top plate; a first clamping plate fixedly connected to the bottom end of one side of the top plate; a second clamping plate disposed opposite to the first clamping plate and slidably connected at its top end to the bottom end of the top plate; a rubber plate disposed on the opposite sides of the first clamping plate and the second clamping plate; and a driving member disposed between the second clamping plate and the top plate for adjusting the distance between the second clamping plate and the first clamping plate.

[0009] Preferably, the driving component includes: a side plate located on the side of the second clamping plate away from the first clamping plate and whose top end is connected to the bottom end of the top plate; a driving screw with one end threaded through the side plate and rotatably connected to the first clamping plate; and a knob fixedly connected to the other end of the driving screw.

[0010] Preferably, the leveling component includes: a fixed rod that is fixedly disposed at the top of the top plate, is hollow inside and has an opening at one end facing the first clamping plate, a telescopic rod that is slidably disposed at one end in the fixed rod, a first locking bolt that is threaded through the side wall of the fixed rod and abuts against the side wall of the telescopic rod at its end, and a scale line disposed on the surface of the telescopic rod.

[0011] Preferably, the height adjustment component includes: a sliding sleeve connected to the end of the telescopic rod, a sliding rod that passes through and slides within the sliding sleeve, a positioning groove formed thereon along the length of the sliding rod, an anti-slip layer disposed at the bottom of the positioning groove, a second locking bolt threaded through the side wall of the sliding sleeve and with its end abutting against the anti-slip layer at the bottom wall of the positioning groove, and an elevation adjustment component connected to the sliding rod, wherein the bottom end of the sliding rod is connected to the positioning plate.

[0012] Preferably, the end of the first locking bolt that abuts against the telescopic rod and the end of the second locking bolt that abuts against the positioning groove are both provided with rubber sleeves.

[0013] Preferably, the elevation adjustment component includes: an elevation rod arranged parallel to the slide rod, and a connecting rod connecting the top of the elevation rod and the top of the slide rod, wherein the bottom end of the elevation rod is located on the same horizontal plane as the bottom surface of the positioning plate, and the elevation rod is located outside the casting template of the lower support pier.

[0014] Preferably, the top of the positioning plate is provided with a connecting plate, and the bottom end of the slide rod is connected to the connecting plate by bolts.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] 1. This utility model achieves stable fixation of the positioning plate above the rebar cage by clamping and fixing the clamping component to the template. The horizontal adjustment component can precisely control the horizontal distance between the positioning plate and the template to achieve centering of the positioning plate. The height adjustment component can achieve stepless adjustment of the height of the positioning plate to ensure accurate installation elevation. The positioning and installation process does not require repeated cutting or welding, which significantly improves construction efficiency. The four sets of positioning adjustment components are evenly distributed and can simultaneously adjust the levelness, elevation and planar position of the positioning plate to achieve three-dimensional precise positioning of the positioning plate, thereby effectively improving the installation quality and seismic performance of the subsequent seismic isolation bearings.

[0017] 2. This utility model adjusts the distance between the second clamping plate and the first clamping plate by driving the screw, and increases the friction by combining the rubber plate, thereby achieving flexible clamping and rigid locking of the template. The self-locking characteristic of the drive screw thread ensures that the clamping force is stable and lasting, preventing the clamping parts from loosening during construction and ensuring the stability of the positioning plate during construction, thereby improving the installation quality of the seismic isolation support.

[0018] 3. This utility model uses scale lines in conjunction with the sliding of the telescopic rod to intuitively control the horizontal distance between the positioning plate and the template, achieving millimeter-level planar position calibration. The first locking bolt quickly locks the position of the telescopic rod, eliminating the manual alignment step in the traditional centering positioning process, reducing operational complexity, improving construction efficiency, and avoiding subjective errors in manual alignment.

[0019] 4. This utility model allows for precise adjustment of the installation elevation of the positioning plate by sliding the sliding rod up and down within the sliding sleeve and fixing the position of the sliding rod with the second locking bolt. The elevation rod is kept at the same level as the bottom surface of the positioning plate and is exposed on the outside of the template, providing a direct reference for elevation measurement and verification, and further improving the convenience and accuracy of positioning plate installation.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0029] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] like Figures 1 to 3 As shown, the auxiliary structure for seismic isolation bearings in buildings includes a positioning plate 1 and four sets of positioning adjustment components 2 evenly distributed around the periphery of the positioning plate 1. The positioning adjustment components 2 include: a clamping member 3 for clamping and fixing on the casting template of the lower support pier; a horizontal adjustment member 4 connected to the clamping member 3 and capable of adjusting the horizontal distance between the side of the positioning plate 1 and the clamping member 3; and a height adjustment member 5 connected between the positioning plate 1 and the horizontal adjustment member 4.

[0033] It should be noted that during actual construction, the corresponding positioning plate 1 should be selected according to the model of the seismic isolation bearing. When the auxiliary structure is installed on the casting template of the lower support, the anchor sleeve used to install the seismic isolation bearing should be installed in the corresponding installation hole of the positioning plate 1 so that it is pre-embedded in it when the concrete is poured. When the lower support is circular, the positioning adjustment component 2 is clamped at equal intervals on the circumference of the circular template. When the lower support is rectangular, the positioning adjustment component 2 should be clamped on the four sides of the rectangular template respectively.

[0034] The implementation process of this technical solution involves first precisely controlling the horizontal distance between the positioning plate 1 and the template based on the spacing between the templates and the size of the positioning plate 1 using the horizontal adjustment component 4, ensuring that the embedded plate is centered. Then, the corresponding clamping components 3 are clamped onto the template, and the horizontal state of the positioning plate 1 is detected by an external level. Each clamping component 3 is then finely adjusted. After the positioning plate 1 is in a horizontal state, the clamping components 3 are further locked to securely fix it on the template. Then, the positioning plate 1 is infinitely adjusted in the height direction using the height adjustment component 5 to reach the set elevation, thus completing the precise installation of the embedded plate. After the concrete of the lower support pier is poured and solidified, the clamping components 3 are released, and the auxiliary structure can be dismantled. This technical solution eliminates the need for repeated cutting or welding during the positioning and installation process, making it convenient to operate and significantly improving construction efficiency. The four sets of positioning adjustment components 2 are evenly distributed and can simultaneously adjust the horizontality, elevation, and planar position of the positioning plate 1, achieving three-dimensional precise positioning of the positioning plate 1, thereby effectively improving the installation quality and seismic performance of the subsequent seismic isolation bearings.

[0035] like Figure 3 As shown, the clamping member 3 includes: a top plate 8, a first clamping plate 6 fixedly connected to the bottom end of one side of the top plate 8, a second clamping plate 7 disposed opposite to the first clamping plate 6 and slidably connected at its top end to the bottom end of the top plate 8, a rubber plate 9 disposed on the opposite sides of the first clamping plate 6 and the second clamping plate 7, and a driving member disposed between the second clamping plate 7 and the top plate 8 for adjusting the distance between the second clamping plate 7 and the first clamping plate 6.

[0036] The driving component includes: a side plate 10 located on the side of the second clamping plate 7 away from the first clamping plate 6 and whose top end is connected to the bottom end of the top plate 8; a driving screw 11 with one end threaded through the side plate 10 and rotatably connected to the first clamping plate 6; and a knob 12 fixedly connected to the other end of the driving screw 11.

[0037] During construction, the knob 12 at the end of the rotating drive screw 11 moves the second clamping plate 7 toward the first clamping plate 6. The rubber plates 9 on both sides contact the template surface to form a preliminary clamp. At this time, the clamping force is small, allowing the clamping parts 3 to move slightly on the template for adjustment. At this time, the positioning plate 1 can be adjusted to be horizontal with the assistance of an external tool (level). After confirming that the level of the positioning plate 1 is correct, the drive screw 11 is rotated again to further increase the clamping force between the second clamping plate 7 and the first clamping plate 6, so that the rubber plates 9 are tightly attached to the template. This makes the entire auxiliary structure stably fixed on the template, ensuring the stability of the positioning plate 1 during construction, facilitating the adjustment of the elevation and the pouring of the support piers, and thus improving the installation quality of the seismic isolation bearing.

[0038] like Figure 1 As shown, the horizontal adjustment component 4 includes: a fixed rod 13 that is fixedly disposed at the top of the top plate 8, is hollow inside and has an opening at one end facing the first clamping plate 6; a telescopic rod 14 that is slidably disposed at one end inside the fixed rod 13; a first locking bolt 15 that is threaded through the side wall of the fixed rod 13 and abuts against the side wall of the telescopic rod 14; and a scale line 16 disposed on the surface of the telescopic rod 14.

[0039] Before installing the auxiliary structure, observe the scale line 16 on the horizontal adjustment component 4 according to the pre-embedded plate plane position and the spacing between the templates as required by the design. Adjust the extension length of the sliding telescopic rod 14 and tighten the first locking bolt 15. The first locking bolt 15 abuts against the side wall of the telescopic rod 14 to fix the position of the telescopic rod 14. When the casting template is circular, the extension length of the telescopic rod 14 should be the same. When the casting template is rectangular, the extension length of the relatively set telescopic rods 14 should be the same. This ensures that the positioning plate 1 is centered, achieving 1 mm-level plane position calibration of the positioning plate. It simplifies the manual alignment steps in the traditional centering positioning process, reduces the complexity of operation, improves construction efficiency, and avoids the subjective error of manual alignment.

[0040] like Figure 2 As shown, the height adjustment component 5 includes: a sliding sleeve 17 connected to the end of the telescopic rod 14; a sliding rod 18 that passes through and slides within the sliding sleeve 17; a positioning groove 19 formed on the sliding rod 18 along its length; an anti-slip layer 20 disposed at the bottom of the positioning groove 19; a second locking bolt 21 threaded through the side wall of the sliding sleeve 17 and with its end abutting against the anti-slip layer 20 on the bottom wall of the positioning groove 19; and an elevation adjustment component connected to the sliding rod 18, wherein the bottom end of the sliding rod 18 is connected to the positioning plate 1.

[0041] The elevation adjustment component includes: an elevation rod 22 arranged parallel to the slide rod 18, and a connecting rod 23 connecting the top of the elevation rod 22 and the top of the slide rod 18. The bottom end of the elevation rod 22 is located on the same horizontal plane as the bottom surface of the positioning plate 1, and the elevation rod 22 is located outside the lower support pier casting template.

[0042] When adjusting the elevation of the positioning plate 1, use an external device (total station) to observe the height of the bottom of the elevation rod 22 outside the template to determine if it is aligned with the preset elevation line. If it is not aligned, loosen the second locking bolt 21 to release the lock on the slide rod 18. Slide the slide rod 18 up and down within the sliding sleeve 17. The movement of the slide rod 18 will not only move the positioning plate 1 but also move the elevation rod 22. Adjust the installation elevation of the positioning plate 1 until the height of the bottom of the elevation rod 22 is aligned with the preset elevation line. Tighten the second locking bolt 21 so that its end abuts against the positioning groove 19 to fix the slide rod 18.

[0043] The positioning groove 19 and anti-slip layer 20 on the slide bar 18 are designed to prevent the slide bar 18 from sliding down accidentally. The elevation bar 22 is kept at the same level as the bottom surface of the positioning plate 1 and is exposed on the outside of the template, providing a direct reference for the measurement and verification of elevation, and further improving the convenience and accuracy of the installation of the positioning plate 1.

[0044] To increase friction and enhance locking stability, rubber sleeves are provided at the ends of the first locking bolt 15 that abut against the telescopic rod 14 and at the ends of the second locking bolt that abut against the positioning groove 19.

[0045] To accommodate the installation requirements of positioning plates 1 of different specifications, a connecting plate 24 is provided at the top of the positioning plate 1, and the bottom end of the slide rod 18 is connected to the connecting plate 24 by bolts, thereby realizing quick assembly and disassembly of the positioning adjustment component 2 and the positioning plate 1.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made without departing from the spirit and scope of this utility model as defined in the appended claims.
