Problems solved by technology

[0008] In order to solve the deficiencies of the existing technology, the present invention provides an adjustable rubber bearing that can be adjusted in three dimensions and is easy to install. It is necessary to realize zero stress inside the installation process, and at the same time solve the problems in the maintenance stage of the existing rubber bearing. Once the rubber body is deformed, it can be corrected through secondary operations

Embodiment 1

[0063] The basin type rubber bearing has the following structure.

[0064] The upper support plate 100, the upper support plate 100 is welded steel plate, such as Q235 steel plate welded, including the horizontal plate part and the surrounding steel plate, the surrounding steel plate is welded on the lower surface of the horizontal plate, forming an enclosed area I101 , this area is used to fit the sliding liner 102. Usually, the liner uses a polyurethane board. In the present invention, the sliding liner 102 is a composite structure, which is made of polyurethane and a lead core board. That is to say, a lead core board is compounded inside the polyurethane board, and the lead core board has good shock absorption performance. In one of the preferred modes, the polyurethane board is pre-bonded in the area I by using asphalt as an adhesive to form an integrated structure, which facilitates the installation process.

Embodiment 2

[0085] In this embodiment, the height of the surrounding steel plates in the upper and lower support plates is extended to form overlapping structures. The existence of overlapping structures can effectively ensure the safety of the upper and lower support plates, avoid slipping out, and form a safe For protection, under this structure, the elastic body setting on both sides can be omitted, further simplifying the structure setting.

Embodiment 3

[0087] On the basis of Embodiment 1, the rubber shock absorber 200 is improved, and a through hole penetrating from top to bottom is provided in the rubber shock absorber. There are a plurality of through holes, which are evenly arranged inside the rubber shock absorber. A lead rod or brass rod 204 is inserted into each through hole. Since this metal rod has better rigidity than rubber, under non-vibrating conditions, the metal rod can share the weight of the bridge body, which can effectively reduce the The load bearing of the rubber improves the service life of the rubber bearing.

[0088] In this embodiment, considering the large deformation capacity of the rubber shock absorber, the height of the metal rod is about 10% to 5% lower than that of the rubber shock absorber, so that the combined advantages of the metal rod and the rubber material can be fully utilized.

Abstract

The invention discloses an adjustable rubber support and a mounting method thereof and an adjusting method thereof. The adjustable rubber support comprises an upper support plate, a rubber shock absorbing body and a lower support plate; an upper anchorage component is arranged on the upper support plate; and a lower adjustable anchorage component is arranged on the lower support plate, wherein a grouting passage and a grouting hole which communicate with inside and outside of an area II are formed in the lower support plate; the rubber shock absorbing body has a sliding space within an area I;the rubber shock absorbing body is in spiral fit matched with the lower support plate; the spiral fit is loose fit for gas to pass through; and a rigid filling body is in an area between the area IIand the rubber shock absorbing body. Moreover, the lower adjustable anchorage component has a function of adjusting the horizontal position at wills. The adjustable rubber support has the characteristics that the mounting and adjusting within a three-dimensional space are convenient; and in particular, due to the application of the lower adjustable anchorage component, the mounting accuracy of ananchorage embedded piece is simplified; and the construction is convenient.

Description

technical field [0001] The invention relates to the technical field of rubber bearings for bridges. Background technique [0002] Basin rubber bearing, basin rubber bearing is a new type of bridge bearing composed of steel components and rubber, usually composed of upper seat plate, sealing ring, rubber plate, bottom basin, anchor bolts and dust cover, etc., with It has the characteristics of large bearing capacity, large horizontal displacement, flexible rotation, etc., and has the advantages of light weight, compact structure, simple structure, low building height, convenient processing and manufacturing, saving steel and reducing cost. [0003] refer to Figure 1 to Figure 5 , an example of the application of ordinary rubber bearings, the current problems of rubber bearings: [0004] The internal stress generated during installation is caused by installation errors, hole opening errors, etc. Usually due to the initial state of the installation. [0005] The internal st...
