Abstract
The utility model belongs to the technical field of bridge bearing and discloses a sphere tensile bearing. The main technical characteristics of the bearing are that: the bearing comprises a upper bearing plate, an upper cover and a lower bearing plate, the middle of which is provided with a steel linear plate; a convex lug is arranged at the top end of the lower bearing plate, a groove and a convex tooth are arranged at the bottom end of the upper cover, a convex ring is arranged at the top end of the upper cover, and a pulling handle is arranged at the bottom part of the upper bearing plate. When in assembly, the groove on the upper cover is aligned with the convex lug on the lower bearing plate and is arranged, then the upper cover is rotated, thus leading the convex tooth to be aligned with the convex lug, and the pulling handle on the upper bearing plate is aligned with the convex ring on the upper cover and is pushed into a preset position. At the moment, all parts of the sphere tensile bearing are connected into one body, when vertical tensile force and lateral shearing force are generated in earthquake, the pulling handle acts on the convex ring, the convex acts on the convex lug, thus leading the vertical tensile force and the lateral shearing force to be counteracted on the basis of keeping the whole bearing to be complete and ensuring compaction and normal use of the bearing structure.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of ball-type mode tensile supporting seat.
Background technology
In bridge construction, horizontal movement that produces for adaptive temperature variation etc. and corner, shock attenuation needs need erection support to carry out the horizontal force that transmits on pressure-bearing and the transfer beams.Presently used spherical bearing comprises upper base plate, loam cake and has the following seat board of middle steel liner plate.The ball-type neoprene bearing of this structure in use can only bear horizontal force and pressure, can not be to the pulling force generation effect of vertical direction.The beam or the frame that falls easily fall when earthquake takes place.
The utility model content
Problem to be solved in the utility model just provide a kind of can be to the ball-type mode tensile supporting seat of the pulling force generation effect of vertical direction.
For solving the problems of the technologies described above, the technical scheme that the utility model ball-type mode tensile supporting seat adopts is: the following seat board of steel liner plate in the middle of comprising loam cake and having, the described top of seat board down is provided with at least two lugs, and the bottom of loam cake is provided with groove and the double wedge that quantity, shape and lug are complementary.
Its additional technical feature is: the top of described loam cake is provided with bulge loop, is provided with upper base plate above the loam cake, and the bottom of upper base plate is provided with the handle that is complementary with bulge loop; Described bulge loop is a polygon, and shaking hands to the cross section is the bar shaped of L type; Described lug, groove and double wedge are 4 that evenly are provided with; Described handle and upper base plate flexibly connect or are connected as a single entity.
Ball-type mode tensile supporting seat provided by the utility model, compared with prior art, the top of following seat board is provided with lug, and the bottom of loam cake is provided with groove and the double wedge that is complementary with lug, the top of loam cake is provided with bulge loop, and the bottom of upper base plate is provided with the handle that is complementary with bulge loop.During assembling, the lug of seat board under the groove alignment of loam cake is put down, rotate loam cake then, make the alignment of double wedge and lug.The bulge loop of again handle of upper base plate being aimed at loam cake pushes the precalculated position and gets final product.The bearing each several part of this moment connects as a whole, when earthquake produced vertical pulling force and cross shear, handle was to the bulge loop effect, and double wedge is to the lug effect, whole bearing is offset vertical pulling force and cross shear on the basis that is kept perfectly, guarantee the compactness and normal use of seat structure.Transmission, rotation, the movement requirement of the counter-force that can satisfy various load well and produced, under huge seismic force effects at random, as long as upper and lower structure is not destroyed itself, therefore plant the bearing existence and just catastrophic effects such as Luo Liang, the frame that falls can not take place, possess the ability of antiseismic earthquake intensity 9 degree of energy.And the volume of bearing and highly more common spherical bearing significantly reduce, and be in light weight, be convenient to install, and to compare cost lower with the steel support of same bearing capacity, can reduce bridge end saddle weight.In addition, bulge loop is a polygon, and shaking hands to the cross section is the bar shaped of L type, makes easy to assemblyly, and as required, handle can flexibly connect with upper base plate or be connected as a single entity.

Fig. 4 is the structural representation of following seat board.
The specific embodiment
Be described in further details below in conjunction with the structure and the principle of accompanying drawing ball-type mode tensile supporting seat provided by the utility model.
As shown in Figure 1, ball-type mode tensile supporting seat provided by the utility model comprise upper base plate 1, loam cake 2 and have in the middle of the following seat board 4 of steel liner plate 3, the top of following seat board 4 is provided with lug 5, the bottom of loam cake 2 is provided with double wedge 6, the top of loam cake 2 is provided with bulge loop 7, and the bottom of upper base plate 1 is provided with handle 8.As shown in Figure 2, the handle 8 of upper base plate 1 bottom is the bar shaped of L type for the cross section.As shown in Figure 3, the bottom of loam cake 2 evenly is provided with 4 double wedges 6 and groove 9, and the bulge loop 7 on loam cake 2 tops is a polygon.As shown in Figure 4, even 4 lugs 5 that are provided with in the top of following seat board 4.
During assembling, the lug of seat board 4 under the groove alignment of loam cake 2 is put down, rotate loam cake 2 then, make double wedge 6 and lug 5 alignment.The bulge loop 7 of again handle 8 of upper base plate 1 being aimed at loam cakes 2 pushes the precalculated position and gets final product.The bearing each several part of this moment connects as a whole, when earthquake produces vertical pulling force and cross shear, 8 pairs of bulge loops 7 effect of shaking hands, 5 effects of 6 pairs of lugs of double wedge, whole bearing is offset vertical pulling force and cross shear on the basis that is kept perfectly, guarantee the compactness and normal use of seat structure.According to the different requirements of one-way support, bilateral support and fixed bearing, on fixed bearing, can not install seat board 1.
