Description

Technical Field

[0001] This utility model relates to the field of seismic isolation technology for building structures, and in particular to an auxiliary installer for seismic isolation bearings in buildings. Background Technology

[0002] Seismic isolation bearings, as important seismic-resistant components, play a crucial role in modern building engineering. By installing seismic isolation bearings in the lower part of a building or between floors, they effectively isolate the transmission of seismic energy to the upper structure, prolonging the natural period of the upper structure, thereby reducing the seismic response of the upper structure, meeting seismic fortification requirements, and ensuring the safety of the building structure. With the continuous development of the construction industry, the application of seismic isolation bearings is becoming increasingly widespread, especially in earthquake-prone areas, where market demand continues to grow. Therefore, developing an efficient and precise auxiliary installation device for seismic isolation bearings is of significant practical importance and has broad application prospects for improving construction efficiency and ensuring installation quality.

[0003] In the prior art, patent document CN116717092A discloses a flatness and position adjustment device and method for installing seismic isolation bearings. This device mainly includes a positioning embedded plate, a height adjustment mechanism, and a horizontal position adjustment mechanism. The positioning embedded plate is supported on the height adjustment mechanism, which adjusts the elevation and flatness in the vertical direction; the horizontal position adjustment mechanism adjusts the left-right and front-back positions in the horizontal plane through auxiliary positioning holes. Although this solution improves the installation accuracy of seismic isolation bearings to some extent, it has some obvious drawbacks. First, the device has low integration and a relatively dispersed structure, requiring assembly on-site, which not only increases the complexity of construction but may also lead to assembly errors. Second, the horizontal position adjustment mechanisms in the same group need to be adjusted synchronously, which is difficult in practice and prone to inconsistencies, thus affecting installation accuracy. Furthermore, this dispersed structural design reduces on-site construction efficiency and increases construction costs.

[0004] Given the aforementioned deficiencies in existing technologies, it is particularly necessary to develop a building seismic isolation bearing auxiliary installer that is highly integrated, compact in structure, and easy to quickly adjust on-site. Utility Model Content

[0005] The present invention aims to provide an auxiliary installer for building seismic isolation bearings to overcome the shortcomings mentioned above.

[0006] In order to achieve the above objectives, the technical solution of this utility model is as follows:

Detailed Implementation

[0035] 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.

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Reference Figure 1-2 This utility model provides an auxiliary installer for building seismic isolation bearings, including a positioning embedded plate 1, a horizontal adjustment mechanism, and a telescopic rod mechanism.

[0038] The positioning embedded plate 1 is a square structure used to determine the elevation and levelness of the top surface of the concrete support during concrete pouring, and to ensure the accurate installation position of the seismic isolation bearing. A pouring vent 2 is provided in the center of the positioning embedded plate 1 to expel air bubbles during concrete pouring, ensuring a smooth concrete surface. Anchor bar installation holes 3 are also provided at the four corners of the positioning embedded plate 1 for installing the embedded anchor bars of the seismic isolation bearing; their positions and diameters match the installation holes on the base plate of the seismic isolation bearing.

[0039] Four horizontal adjustment mechanisms are fixedly connected to the lower surface of the positioning embedded plate 1, and are respectively set at the middle position near each side of the positioning embedded plate 1. Four telescopic rod mechanisms are set along the vertical direction, and their upper ends correspond one-to-one with the horizontal adjustment mechanisms to form a fixed sliding connection.

[0040] Specifically, each horizontal adjustment mechanism includes a fixed frame 4, a sliding frame 5, and a sliding block 6. The fixed frame 4 is a rectangular frame structure and is fixedly connected to the lower surface of the positioning embedded plate 1. The sliding frame 5 is also a rectangular frame structure and is slidably connected to the fixed frame 4 along the first direction. The sliding block 6 is slidably connected to the sliding frame 5 along a direction perpendicular to the first direction and is fixedly connected to the upper end of the telescopic rod mechanism.

[0041] Two slide rails 7 are provided on opposite sides of the inner wall of the fixed frame 4. The slide rails 7 are arranged along a first direction, which is perpendicular to the edge of the adjacent positioning embedded plate 1. A first slide groove 8 is provided at both ends of the sliding frame 5 perpendicular to the first direction. The first slide groove 8 is slidably connected to the slide rails 7 inside the fixed frame 4. A second slide groove 9 is provided on opposite sides of the inner wall of the sliding frame 5. Two second slide grooves 9 are arranged perpendicular to the first direction. The two ends of the sliding block 6 extend back to form a connecting part. The connecting part passes through and is threadedly connected to a first bolt 10. The first bolt 10 can selectively abut against the positioning embedded plate 1 to fix the position of the sliding block 6.

[0042] This invention achieves a high degree of integration by pre-assembling the horizontal adjustment mechanism and the telescopic rod mechanism into a single unit, and through the structural design of the fixed frame 4, sliding frame 5, and sliding block 6. This integrated design reduces on-site assembly steps, lowers the possibility of assembly errors, and significantly improves construction efficiency. Furthermore, this invention features an independent horizontal adjustment mechanism, where each mechanism can be adjusted independently without the need for synchronous operation. The structural design of the sliding frame and sliding block allows for flexible adjustment of the position of the pre-embedded positioning plate in the horizontal plane, and the position can be fixed by tightening the first bolt, greatly reducing operational difficulty and improving installation accuracy.

[0043] Reference Figure 3-4 The telescopic rod mechanism consists of a sleeve 12, a sliding rod 13, and a second bolt 14. The sleeve 12 is vertically oriented, with a ball bearing 11 rollingly connected to its upper end. The ball bearing 11 rolls in contact with the lower surface of the positioning embedded plate 1, reducing friction and facilitating adjustment. The upper end of the sliding rod 13 passes through the sleeve 12, forming a slidable connection. A third vertical groove 15 is formed on the outer wall of the sliding rod 13. The second bolt 14 is threaded onto the side wall of the sleeve 12 and can selectively abut against the outer wall of the sliding rod 13. A vertical strip-shaped protrusion 16 is provided on the inner wall of the sleeve 12, slidingly connected to the third groove 15 of the sliding rod 13. The second bolt 14 is positioned opposite the third groove 15 to fix the position of the sliding rod 13.

[0044] It should be noted that the positioning embedded plate 1, the horizontal adjustment mechanism and the telescopic rod mechanism in this utility model are all made of steel, and the fixed connection is usually achieved by welding.

[0045] The specific operating steps of this utility model are as follows:

[0046] The first step is to weld the lower end of the sliding rod 13 onto the steel cage on which the seismic isolation bearing pier needs to be installed, ensuring that the sliding rod 13 is in a vertical position. Then, the lower end of the sleeve 12 is fitted onto the upper end of the sliding rod 13, ensuring that the four sides of the positioning embedded plate 1 are parallel to the four sides of the seismic isolation bearing pier.

[0047] The second step is to adjust the elevation of the positioning embedded plate 1. After positioning, the second bolt 14 is screwed in to make it abut against the third sliding groove 15, thereby ensuring relative stability between the sleeve 12 and the sliding rod 13 and realizing the adjustment of the height of the positioning embedded plate 1.

[0048] The third step is to adjust the left and right position and front and back position of the positioning embedded plate 1 to meet the installation accuracy requirements. Then, by tightening the first bolt 10, it is made to abut against the lower surface of the positioning embedded plate 1, thereby completing the locking of the telescopic rod mechanism and the horizontal adjustment mechanism.

[0049] The fourth step is to check and verify the elevation and horizontal position of the positioning embedded plate 1, confirming that they meet the installation requirements of the seismic isolation bearing. If any problems are found, the second bolt 14 needs to be loosened and the second step repeated, and / or the first bolt 10 needs to be loosened and the third step repeated. After confirming that everything is correct, insert the embedded anchor bars of the seismic isolation bearing into the anchor bar installation hole 3, and pour the lower support concrete through the vent hole 2, ensuring that the top surface elevation of the concrete is consistent with the top surface elevation of the positioning embedded plate 1, and ensuring that the concrete surface is flat; after the concrete has solidified and reached the specified strength, the seismic isolation bearing can be installed.
