Abstract
The utility model relates to a spherical base for a bridge, which is composed of a cylindrical base. A steel plate is arranged in the base. The lower end surface of the base is provided with a protruding ring or a poly-fluortetraethylene board. The upper end surface of the base is a sloping spherical surface. The sloping spherical surface of the utility model can adjust installation errors and adapt to integrated slope. The spherical base for a bridge is good in commonality, strong in integral bearing capacity, convenient for installation and construction, low in cost, small in stress concentration degree and without phenomenon of disengagement. In the utility model, the side surface and the top of the cylindrical base are provided with a central line and a scale line, adjusting horizontal slopes and vertical slopes.
Description
The utility model relates to a kind of bridge spherical bearing, particularly is adapted to the bearing of the straight bridge of sloping type, skew bridge, curved bridge.
In current bridge construction, sloping type bridge is more and more, and the simultaneous bridge of horizontal wall inscription and longitudinal gradient has brought very big trouble for bridge design person and construction, cause long in time limit, the engineering cost height.Exist above shortcoming when having only longitudinal gradient exactly too.The bearing that can conveniently design and construct at present, reduce engineering cost and meet Ministry of Communications's industry standard " JT/T4-93 " highway bridge laminated rubber bearing and bridge design standard does not also have, the spherical crown bearing that uses is a kind of bridge rubber bearing that designs for sloping type bridge specially at present, it is to utilize the spherical crown part to contact with the point of beam-ends bottom surface, adapt to longitudinal gradient and horizontal wall inscription, belong to typical some contact phenomena.Cause the partial pressing and the stress concentration phenomenon of this bearing like this, made the aging speed of having accelerated of neoprene bearing, shortened application life.It is very big unfavorable that this has brought application life of bridge and maintenance, the more important thing is that close traffic causes the loss of social benefit.This bearing is when adapting to 2.5% gradient, and the area that comes to nothing reaches 31%-44%, and this is contrary with the Bridges in Our Country design specifications
The purpose of this utility model is to provide a kind of good, whole stressed strong bridge rubber bearing of versatility that can adapt to the comprehensive gradient of 1%-8%
The purpose of this utility model is achieved in that the utility model is made of a cylindric bearing, adds steel plate in the bearing, and the lower end of bearing is provided with bulge loop or adds polyfluortetraethylene plate, and the upper surface of bearing is a slope sphere.The utility model is provided with center line and graduation mark at the side and the end face of cylindric bearing.
The utility model can adapt to the bridge rubber bearing of the comprehensive gradient of 1%-8%, it has can adapt to the comprehensive gradient, versatility is good, whole stressed good, be convenient to design and construction, cost is low, easy for installation, the phenomenon of not coming to nothing, stress concentration degree is little, the mechanical property of product and use the technical requirements that meets industry standard JT/T4-93 of Ministry of Communications and the bridge design standard JTJ023-85 of Ministry of Communications
Accompanying drawing 1 is the utility model sectional view
Accompanying drawing 2 is the utility model vertical view
As shown in Figure 1, the upper end of bearing 2 is one and is gradient shape garden shape spheroid, a spherical surface body is arranged on it is domatic, and the lower end is a cylinder, and two bulge loops are arranged in the cylinder bottom surface, section is the rubber bulge loop 4 of half garden shape, cylinder side or end face own centre line 5, there is graduation mark 6 the center line both sides, and sliding support is added with polyfluortetraethylene plate below its cylinder bearing 2 as shown in Figure 2, the rubber bulge loop that does not have half garden shape, the resistance in the time of can reducing the beam body heat effectively and expand shrinkage.
The utility model slope sphere can be adjusted alignment error, domaticly adapts to the comprehensive gradient; The scale of cylinder side or end face is used to adjust horizontal wall inscription and longitudinal gradient; Cylinder bottom surface half garden shape rubber bulge loop 4 prevents bridge pier end face injustice and designs.
