Utility model content
The purpose of this utility model is the arch bridge abutment providing a kind of high resistance bearing capacity, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of arch bridge abutment of high resistance bearing capacity, comprise reinforcing ring, lower supporting rod, middle bearing, bearing platform, bridge, spring, rubber post, ring-shaped platform and spherical concave surface, the top center of described lower supporting rod is provided with spherical concave surface, spherical concave surface periphery is set to ring-shaped platform, wherein be provided with the spherical end of middle bearing in spherical concave surface, the top of described middle bearing is bearing platform, and bearing platform connects bridge; Be provided with several rubber posts between described bearing platform and ring-shaped platform, rubber post is vertical honeycomb is structure, and honeycomb interior is provided with spring; The below of described spherical concave surface is provided with the reinforcing ring around lower supporting rod, and described lower supporting rod is cylindrical structure.
As further program of the utility model: the upper surface of described spherical concave surface and bearing platform is respectively equipped with frictional resistance layer A and frictional resistance layer B.
As further program of the utility model: described frictional resistance layer A and frictional resistance layer B is the teflon fibre braided thing of super-pressure, Nomex, glass fiber or aramid fiber braid novel wear resistant consumption friction material.
As the utility model further scheme: described reinforcing ring is Stainless Steel welded construction or steel hoop concreting structure.
Compared with prior art, the beneficial effects of the utility model are: this practicality is by lower supporting rod and middle abutment member abutment body, and lower supporting rod and the contact surface of middle bearing are designed to spherical arc contacts, when not increasing abutment bulk volume, increase the load-bearing area of abutment, thus make arch bridge abutment possess high resistance bearing capacity, be provided with several rubber posts between bearing platform and ring-shaped platform simultaneously, when making arch bridge bridge floor stressed, rubber post can absorbing vibration, thus play the effect of damping, avoid contacting of vibration influence lower supporting rod and middle bearing, thus weaken the bearing capacity of abutment, arch bridge abutment described in this practicality has high-bearing capacity and stability, thus improve the performance of arch bridge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of arch bridge abutment of high resistance bearing capacity, comprises reinforcing ring 1, lower supporting rod 2, middle bearing 3, bearing platform 4, bridge 5, spring 6, rubber post 7, ring-shaped platform 8, frictional resistance layer A9, spherical concave surface 10 and frictional resistance layer B11, the top center of described lower supporting rod 2 is provided with spherical concave surface 10, spherical concave surface 10 periphery is set to ring-shaped platform 8, wherein be provided with the spherical end of middle bearing 3 in spherical concave surface 10, by the pressure dissipation that the spherical end will the bearing platform 4 at middle bearing 3 top receive, thus improve the bearing capacity of the bridge 5 that bearing platform 4 connects, the upper surface of described spherical concave surface 10 and bearing platform 4 is respectively equipped with frictional resistance layer A9 and frictional resistance layer B11, to improve anti-wear performance and shock-absorbing capacity, slow down the wearing and tearing of contact surface, and frictional resistance layer A9 and frictional resistance layer B11 is the teflon fibre braided thing of super-pressure, Nomex, glass fiber or aramid fiber braid novel wear resistant consumption friction material, by high temperature resistant binder by this teflon fibrous braid, Nomex, glass fiber or aramid fiber braid reliably bonding with sphere, resistance to compression design bearing capacity can reach 100 ~ 250Mpa, and friction factor is 0.02 ~ 0.10,
