[0015] The present invention will be described in detail below based on the accompanying drawings and specific embodiments. Example

[0016] Now take the plate rubber bearing model GBZY200*56 as an example, that is, the diameter of the bearing is 200mm and the thickness is 56mm, and the structure of the utility model is specifically described:

[0017] The utility model discloses a support positioning auxiliary device for support replacement, wherein the lower end of the support 1 is supported and arranged on the support pad stone 2, and the support positioning auxiliary device includes two rectangular clamps 3 arranged on the left and right, and the opposite sides of the rectangular clamps 3 are open, and the open ends of the rectangular clamps are matched to form a rectangular hole 4 with a side length of 200 mm. The two rectangular clamps 3 are supported and arranged on the support pad stone 2 and are used to be matched and clamped on both sides of the bottom end of the support 1. A connecting piece 5 is also detachably connected between the two rectangular clamps 3, and the connecting piece 5 is used to connect the two rectangular clamps 3 in the matched state into a whole.

[0018] The connecting member 5 comprises screw rods 5.1 respectively arranged at the bottom of the same side ends of the rectangular clamps. The screw rods 5.1 are sleeved on the steel bars 5.2 and locked by nuts 5.3 to achieve the connection of the rectangular clamps 3 in the matched state.

[0019] The outer side of one end of the rectangular clamp 3 away from the screw rod 5.1 is flush with the side of the support pedestal 2, and the outer side wall is connected to a limiting rod 6 which is vertically limited downward on the outer side wall of the support pedestal 2.

[0020] The two rectangular clamps 3, the steel bars 5.2 and the limiting rod 6 are all made of stainless steel.

[0021] The use method of this utility model:

[0022] 1) After pouring the new bearing pad stone, the original embedded steel plate at the bottom of the bridge above bearing 1 is polished and rust-removed until it has a metallic luster. After construction layout is carried out at the corresponding position according to the design drawings, a galvanized steel plate is adhered to the plane layout position of the original embedded steel plate using structural adhesive;

[0023] 2) Place the plate rubber bearing 1 (model GBZY200*56) into the center of the pad stone 2. The upper surface of the bearing 1 should be in close contact with the galvanized steel plate. At this time, a part of the structural adhesive on the galvanized steel plate is squeezed out and cleaned.

[0024] 3) Take two rectangular clamps 3 and place them on the surface of the pad stone 2, and set the limit clamps around the support 1, and make the limit rod 6 attached to the side wall of the pad stone 2, put the steel bar 5.2 between the screws 5.1, and lock it with the nut 5.3.

[0025] 4) Take a 3mm thick mirror steel plate and insert it between the new support and the galvanized steel plate. Squeeze out some of the excess structural adhesive on the galvanized steel plate to ensure that the structural adhesive between the galvanized steel plate and the bottom of the main beam is densely filled without any voids. Remove any excess structural adhesive. When the structural adhesive strength reaches the design strength, the galvanized steel plate and the structural adhesive will form a whole.

[0026] 5) When the strength between the pad stone, galvanized steel plate and structural adhesive reaches 30MPa, the galvanized steel plate and structural adhesive form a whole, and the conditions for dropping the beam are met. At this time, the mirror steel plate is taken out and the beam is dropped synchronously.

[0027] The above description is a specific embodiment of the present application, which will enable those skilled in the art to understand the present application. This device secures the new support at the center of the support pedestal, ensuring that the support position remains unchanged during the support replacement and glue extrusion leveling process, and ensures that the structural adhesive on the galvanized steel plate at the support position is dense, facilitating later construction and being well-suited for practical engineering applications.
