Description

Technical Field

[0001] The utility model belongs to the technical field of bridge supports, and more specifically, relates to a bridge support leveling and installation device. Background Art

[0002] As an important part of the bridge structure, the bridge bearing is a connection point between the upper and lower structures of the bridge. It is also an important part that carries the safety and life of the bridge and cannot be replaced. Therefore, it is very important to ensure the accuracy of the bearing installation position and the accurate determination of the bearing elevation. With the increasing development of construction projects, the types and specifications of bridge bearings are gradually increasing, and the scale of construction is also gradually increasing. Therefore, it is very important to ensure the safety of bearing installation, the accuracy of position and the accuracy of elevation.

[0003] At present, there are no technical measures or means to accurately locate the bearings and their elevations at the construction sites. Usually, the bearings are installed at the position and elevation of cushion stones, and the position and elevation are controlled by steel bars. In the existing patent, a bridge bearing leveling wedge connection method 202110110488.3 includes the following steps: when prefabricating the bridge deck, the upper steel plate is embedded in the prefabricated bridge deck according to the bearing position in the design drawing, and the lower plane of the embedded upper steel plate is flush with the bottom surface of the prefabricated bridge deck, and the prefabricated pedestal bottom membrane does not need to be grooved; according to the wedge block size in the design drawing, the steel wedge block is customized to better meet the variable wedge block size and precision requirements; after the prefabricated bridge deck enters the beam storage area, the steel wedge block is spliced ​​with the embedded upper steel plate; the steel wedge block is welded to the embedded upper steel plate on all sides; the upper steel plate, steel wedge block and welding point are rust-proofed, but this patent requires the steel wedge block to be customized according to the design drawing, and the customized steel wedge block cannot accurately level the bearing.

[0004] The above-mentioned prior art method of installing the bearing based on the position and elevation of the cushion stone may lead to inaccurate control of the bearing elevation due to the inaccurate control of the cushion stone elevation, resulting in insufficient contact between the bearing and the bridge beam and slab, causing uneven force on the bearing or the existence of emptying, seriously affecting the service life of the bearing and endangering the overall structural safety of the bridge. In the method of using steel bars to position and control the position and elevation, there will be certain errors in the processing and production of steel bars, resulting in the inability to accurately control the installation elevation of the bearing, and also causing waste of steel bar raw materials, which is uneconomical and cannot achieve accurate positioning and control. Therefore, it is of great significance to develop a leveling device and construction method for the installation of bearings that is easy to carry and can be used in a turnover manner.
