Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering construction, and specifically relates to an adjustable anti-seismic support positioning plate installation structure. Background Art

[0002] In order to improve and ensure the seismic resistance level of public construction projects, a large number of seismic bearings are installed on the lower piers used to support the concrete foundation floor slabs during the construction of public construction projects. During the installation and construction process, the seismic bearings have very high requirements for accuracy, flatness and elevation error. In order to ensure the construction quality, the traditional practice is to support and set a positioning plate horizontally above the top surface of the steel cage of the lower pier when pouring reinforced concrete lower piers, which is used to control the precise positioning of the embedded bolts and ensure the flatness of the installation surface of the seismic bearings.

[0003] The traditional construction and installation structure of the positioning plate is to vertically weld and fix four positioning plate support steel bars at the straight section of the anchor bars at the four corners of the lower pier steel cage, use a level and other detection tools to measure the elevation of the top of the four support steel bars, use a grinding tool to make the elevation of the top of the four support steel bars at the same height, and then lay the positioning plate on the four support steel bars. The disadvantages of the traditional approach are that the construction is complicated, time-consuming and labor-intensive, and the accuracy is affected by the construction, the elevation error is large and the quality cannot be guaranteed, resulting in the inability to install the seismic bearing or the uneven surface after installation, which not only requires rework but also wastes materials, is time-consuming and labor-intensive, and the most serious is that the seismic bearing does not meet the design requirements, resulting in a lower seismic grade of the building. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of inconvenient setting flatness and elevation adjustment of the positioning plate under the pier of the seismic bearing in the traditional construction method, and to provide an adjustable seismic bearing positioning plate installation structure with adjustable positioning plate support rod height.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the adjustable seismic bearing positioning plate installation structure of the utility model includes a lower pier steel cage, a positioning threaded sleeve, an adjusting screw and a positioning plate; the positioning threaded sleeve is vertically fixedly installed on the top surface of the steel cage of the lower pier steel cage; the adjusting screw is configured and installed on the positioning threaded sleeve; the positioning plate is horizontally arranged above the top surface of the steel cage through the support of the adjusting screw.

[0006] At least three groups of positioning threaded sleeves are evenly arranged at the same horizontal height on the upper edge of the top surface of the lower pier reinforcement cage.

[0007] The positioning threaded sleeve is fixed by welding or a snap-on clamp.

[0008] The adjusting screw adopts a through-thread bolt with a bolt head.

[0009] The top elevations of the adjusting screws are set at the same height.

[0010] The beneficial effect of the utility model is that the construction process is simple and does not require repeated grinding and other construction operations, which optimizes the construction steps, not only reduces the construction process and reduces the construction cost, but also improves the construction efficiency, avoids the waste of construction materials and the economic loss caused by rework; the support elevation can be accurately adjusted by adjusting the screws, ensuring the flatness of the positioning plate and the construction elevation, thereby ensuring the installation quality of the seismic bearing, so that the construction quality is guaranteed through the construction process.

[0016] Example 1

[0017] As attached Figure 1-3 As shown, an adjustable seismic bearing positioning plate installation structure includes a lower pier steel cage 1, a positioning threaded sleeve 2, an adjusting screw 3 and a positioning plate 4; the positioning threaded sleeve 2 is vertically fixedly installed on the steel cage top surface 11 of the lower pier steel cage 1; the adjusting screw 3 is configured and installed on the positioning threaded sleeve 2; the positioning plate 4 is horizontally arranged above the steel cage top surface 11 through the support of the adjusting screw 3.

[0018] At least three groups of positioning threaded sleeves 2 are evenly arranged at the same horizontal height on the top surface 11 of the reinforcement cage 1 of the lower pier.

[0019] The positioning threaded sleeve 2 is fixed by welding or a snap-on clamp.

[0020] The adjusting screw 3 is a through-thread bolt with a bolt head.

[0021] The top elevations of the adjusting screws 3 are set at the same height.

[0022] Example 2

[0023] Combined with the attached drawings, the construction method and principle of the adjustable seismic support positioning plate installation structure of the utility model are as follows:

[0024] 1) Processing and manufacturing a through-thread adjustment screw 3 and a matching positioning thread sleeve 2 assembly of a certain length and diameter.

[0026] 3) Install an adjusting screw 3 on each positioning threaded sleeve 2, and adjust the installation height of the adjusting screw 3 on the positioning threaded sleeve 2 so that the top surface of the bolt head of each adjusting screw 3 is at the same elevation (use a detector to detect the elevation of the top surface of the bolt head of each adjusting screw 3, and adjust the elevation of the top surface of the bolt head of each adjusting screw 3 according to the design error requirements).

[0027] 4) Place the positioning plate 4 on the four adjusting screws 3, and use a level to measure whether the flatness of the positioning plate 4 meets the requirements (if the flatness does not meet the requirements, adjust the adjusting screws 3 to correct it), and at the same time check whether the elevation of the positioning plate 4 meets the requirements.
