Abstract
The invention discloses a bridge support easy to replace. The bridge support comprises a lower support body and an upper support body which are installed on a prier. The lower support body is concave, the upper support body is clamped in the lower support body through a fastening pressing block, and a draining channel is formed in the joint of the lower support body and the upper support body. Two unfolding plates are arranged on the two sides of the lower support body, through holes are formed in the unfolding plates, ejecting blocks are arranged in the through holes, and jacking screws are connected to the lower portions of the ejecting blocks. The bridge support can be conveniently replaced once damaged.
Description
Technical field
The present invention relates to field of bridge construction, be specifically related to a kind of bridge pad of easily more remodeling.
Background technology
Architectural at railway bridge, highway bridge, urban viaduct and various large-scale suspension frame structure, set up between bridge beam body and bridge pier and have bearing the connector as them, the effect of bearing be by the load of bridge pleasantly, be communicated securely to bridge pier up be consistent so that the actual loading situation of bridge is graphic with the theory of calculating.But the connector that bearing is formed a connecting link as bridge, bear the load of bridge beam body transmission for a long time, easily cause the accidents such as cracking, locally concrete destruction, meanwhile, newly building bridge carries out bearing installation or bridge pier produces when settling, and is often easily generated the phenomenon of seat empty, lower supporting plate can be made to cause the height of lower support plate to change base plate pressure break at cavity, cause bridge to subside, cause the vehicle in travelling to have an accident, cause the loss of life and other properties.
Summary of the invention
It is desirable to provide a kind of bridge pad of easily more remodeling, to solve the problems referred to above.
For achieving the above object, technical scheme is as follows:
A kind of bridge pad of easily more remodeling, it is characterised in that: include undersetting, the upper bracket being arranged on bridge pier；Described undersetting is matrix, is connected with upper bracket by fastening briquetting in undersetting, and undersetting and upper bracket junction are provided with drainage channel；Described undersetting both sides are provided with two panels, and panel has through hole, and is provided with jacking block in through hole, and connecting below jacking block has lift-bolt.
Further, being provided with the conical surface bottom described fastening briquetting, undersetting inner face is also equipped with and fastens the clamping conical surface that the briquetting conical surface matches, and the clamping cone over glaze in bearing is more than the axial angle of the conical surface fastening briquetting to angle.
Further, it is provided with compression clearance between described fastening briquetting and undersetting.
The beneficial effects of the present invention is: the present invention is designed as the conical surface at the inner face of undersetting, and fastening briquetting also is provided with the conical surface, and the clamping cone over glaze in bearing is more than the axial angle of the conical surface fastening briquetting to angle, that is, when upper bracket load is constantly sunk, it can promote fastening briquetting constantly towards bottom offset, two conical surfaces start extruding, due to the tapering of two conical surfaces and differ, its contact portion starts as single-point, it can produce radial force in extrusion process, shunts the pressure born, and the most just serves the effect of fastening.
Secondly, the present invention is after load is unbalance, when needing the replacement carrying out bridge pad, can be risen by the jacking block jack of panel, replace upper bracket to carry out temporary transient support, can carry out the replacement of upper bracket.
Accompanying drawing explanation
Fig. 1 is the bridge pad structural representation of easily more remodeling that the present invention provides.
Labelling in figure: 1 be undersetting, 2 be upper bracket, 3 be fastening briquetting, 4 be the briquetting conical surface, 5 be the clamping conical surface, 6 be lift-bolt, 7 for jacking block.
Detailed description of the invention
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of bridge pad of easily more remodeling, it is characterised in that: include undersetting 1, the upper bracket 2 being arranged on bridge pier；Described undersetting 1 is matrix, is connected with upper bracket 2 by fastening briquetting 3 in undersetting 1, and undersetting 1 and upper bracket 2 junction are provided with drainage channel；Described undersetting 1 both sides are provided with two panels, and panel has through hole, and is provided with jacking block 7 in through hole, and connecting below jacking block 7 has lift-bolt 6.Being provided with the conical surface 4 bottom described fastening briquetting 3, undersetting 1 inner face is also equipped with and fastens the clamping conical surface 5 that briquetting 3 conical surface matches, and the clamping axial angle of the conical surface 5 in bearing is more than the axial angle of the conical surface of fastening briquetting 3.It is provided with compression clearance between described fastening briquetting 3 and undersetting 1.
When practicality, the present invention is designed as the conical surface at the inner face of undersetting 1, and fastening briquetting 3 also is provided with the conical surface, and the clamping axial angle of the conical surface 5 in bearing is more than the axial angle of the conical surface of fastening briquetting 3, that is, when upper bracket 2 load is constantly sunk, it can promote fastening briquetting 3 constantly towards bottom offset, two conical surfaces start extruding, due to the tapering of two conical surfaces and differ, its contact portion starts as single-point, and it can produce radial force in extrusion process, the pressure born is shunted, the most just serves the effect of fastening.Secondly, the present invention is after load is unbalance, when needing the replacement carrying out bridge pad, can be risen by the jacking block 7 of panel jack, replace upper bracket 2 to carry out temporary transient support, can carry out the replacement of upper bracket 2.After replacing completes, jacking block can be declined, re-use upper bracket and carry out load.Present configuration is simply, easily realize, it is possible to achieve the local of bridge pad is changed online, reduces maintenance time.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
