Description

Technical Field

[0001] The utility model relates to the technical field of isolation bearing installation, in particular to the installation and leveling of the positioning embedded steel plate under the isolation bearing, and specifically to an adjusting device for controlling the vertical elevation and flatness of the positioning plate of the isolation bearing. Background Technique

[0002] The traditional "rigid earthquake resistance" design method mainly resists earthquakes by enhancing the strength, stiffness and ductility of building structures. However, once the structure is damaged, it will still cause great losses. The isolation technology isolates and absorbs seismic energy by setting an isolation layer, reducing the seismic response of the superstructure above the isolation layer. Compared with simple rigid earthquake resistance, it is more effective in reducing the damage to building structures and the damage to personnel and property caused by earthquakes. Therefore, the isolation technology is more and more widely used in modern buildings, and the most representative application of the isolation technology is the isolation bearing technology.

[0003] The isolation bearing is set in the isolation layer, generally installed between the lower pier and the upper pier, and is a device used to bear the weight of the superstructure and have the ability of isolation horizontal deformation. During the installation process of the isolation bearing, the precise positioning and installation of the positioning embedded plate below it is the key to ensuring the accurate installation elevation and flatness quality of the isolation bearing. Therefore, the elevation and flatness requirements of the positioning plate are extremely precise. However, due to the very dense arrangement of structural steel bars in the concrete lower pier, it is difficult to accurately install the positioning plate. How to achieve the accurate installation of the positioning plate is a difficult problem in construction production and a key point in construction quality control.

[0004] The existing adjustment technology devices for positioning plates are cumbersome to operate, complex in process, poor in practicability and versatility, and difficult to be popularized and applied to the construction site, and the installation accuracy effect of the positioning plate is generally average. Therefore, it is necessary to develop a positioning plate horizontal adjustment device that can be accurately adjusted and is easy to operate to completely solve the accurate installation of the positioning plate. Summary of the Utility Model

[0005] In order to solve the deficiencies of the existing technology mentioned above, the utility model provides a simple device for leveling the positioning plate of the isolation bearing. After vertically fixing the single-head screw on the structural steel bars of the lower pier, by finely adjusting the hexagon nut at the top of the screw up and down, the top surface is made to be in the elevation plane of the positioning plate, so as to achieve the rapid and accurate leveling of the positioning plate.

[0006] To achieve the above purpose, the specific technical solution adopted by the utility model is:

[0007] A simple device for leveling the positioning plate of the isolation bearing includes a single-head screw and a hexagon nut. The end of the single-head screw is provided with a threaded section, and the single-head screw and the hexagon nut are rotated up and down slidably through thread cooperation to achieve height adjustment.

[0008] The above-mentioned simple device for leveling the isolation bearing positioning plate, when using the device, first find out the approximate placement height of the screw according to the elevation of the isolation bearing positioning plate, then adjust the screw vertically, and fix it with the lower pier structure steel bar by spot welding, then insert the nut into the top of the screw, and fine-tune the nut by rotating it up and down to accurately adjust it to the bottom elevation of the positioning plate, and the screws and nuts of the remaining groups are installed in the same way. After all the screws are adjusted, install the positioning plate, and check the overall flatness and elevation of the positioning plate until the allowable error requirements are met, and the operation of the device is now complete.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model realizes a method for controlling the elevation and flatness of a positioning plate that can be dynamically adjusted and accurately determine the elevation by adjusting the height of the hexagonal nut at the top of the screw rod, changes the traditional method of using welding short steel bar heads as a positioning device, and solves the disadvantages of difficulty in positioning short steel bars, low precision, low efficiency and complicated operation.

[0011] A simple device for leveling a seismic isolation bearing positioning plate, wherein the diameter of the single-head screw should not be less than 12 mm, the length of the single-head screw should be 200 mm, the length of the hexagonal nut should not be less than 40 mm, and the single-head screw and the hexagonal nut are made of steel.

[0012] The utility model has the advantages of easy-to-obtain materials, low price, convenient operation, good versatility and practicality, simplifies the positioning process and operation difficulty of the positioning plate, thereby improving the construction efficiency and construction quality, and saving time and labor costs.
