Functional separation type combined support system and its construction method

Abstract

The invention provides a functional separation type combined support system and its construction method. The support system is fixed between a beam body and a pier, the middle of a cross bridge on thetop of the pier is provided with a self-resetting lead-core rubber support, and the two sides of the cross bridge are provided with pot-shaped rubber support. The self-resetting lead-core rubber support includes an upper support steel plate A, a deformation constraint plate, a first connection steel plate, a rubber plate A, a second connection steel plate, a bottom plate and a lower support steelplate; the upper support steel plate A is fixed on the bottom of the beam body, the upper support steel plate A, the deformation constraint plate, the first connection steel plate, the rubber plate A, the second connection steel plate and the bottom plate are connected in sequence, and the lower portion of the lower support steel plate is fixed on the top of the pier. The pot-shaped rubber support includes an upper support steel plate B, a stainless steel plate, a sliding plate, an intermediate lining plate, a rubber plate B and a steel pot. The functional separation type combined support system and its construction method are disclosed, the function of a single support is simplified, the processing difficulty of the single support is reduced, and the cost is reduced. When the performanceof the support is damaged, the support is convenient to replace and maintain.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a group of function-separated composite bearing systems and a construction method thereof. Background technique [0002] At present, in order to improve the performance of bearings in our country, most of them adopt the function separation design on a single bearing. Generally speaking, the function-separated support needs to meet the following functions: 1. Vertical support function; 2. Horizontal shear deformation function; 3. Rotation deformation function. Different parts of the support take on different functions. However, the structure of this kind of support is complicated, and the processing accuracy is high, resulting in high cost. [0003] In addition, the lead core rubber bearings widely used at present, when the bearing undergoes horizontal shear deformation, the lead core inside the bearing will produce plastic deformation, but due to the insu...

However, this type of support has a complex structure and requires high machining accuracy, resulting in high cost

[0003] In addition, the lead core rubber bearings widely used at present, when the bearing undergoes horizontal shear deformation, the lead core inside the bearing will produce plastic deformation, but due to the insufficient attenuation performance and reset ability of the bearing, the accumulated plastic of the lead core The deformation of the shape will lead to the loss of the horizontal shear deformation function of the support
