Technical scheme: for solving the problems of the technologies described above, tension and compression rod-type steel of the present utility model and concrete combination beam bridge anti-overturning devices adopt following technical scheme:
A kind of tension and compression rod-type steel and concrete combination beam bridge anti-overturning devices, described steel and concrete combined structure beam bridge comprise web, bearing, bent cap and pier stud, described bent cap is arranged on the described pier stud, described bearing is arranged on the described bent cap, described web is arranged on the described bearing, described anti-overturning devices comprises otic placode, fork-shaped otic placode and strut and tie, described otic placode is arranged on the side of described web, described fork-shaped otic placode is connected by bearing pin with described otic placode, one end of described strut and tie is fixed on a side of described bent cap, and the other end of described strut and tie connects described fork-shaped otic placode.
Preferably, be provided with composition backing between described strut and tie and the described bent cap.
Preferably, described composition backing connects described bent cap by the weldering nail.Composition backing forms integral body by the weldering nail with bent cap
Preferably, described strut and tie is in the bilateral symmetry setting of described bent cap.
Preferably, the junction of described strut and tie and described composition backing is provided with stiffening rib.Strut and tie is by being provided with stiffening rib and composition backing forms integral body.
Preferably, described strut and tie is a chain link.Strut and tie can replace with chain link, but prefabrication can effectively relax impact, and simple structure is installed easily.
Beneficial effect: tension and compression rod-type steel of the present utility model and concrete combination beam bridge anti-overturning devices, be a kind of by the joint construction way of strut and tie device is set between box beam web and bent cap, this form of structure has improved the globality of bridge construction superstructure, thereby the anti-seismic performance of bridge is improved.Only stub under the overload effect, laterally stability against overturning is poor, can prevent effectively that by this device the beam body from falling or throw off.Site operation adopt the weldering nail carry out with bent cap be connected easy construction.
Description of drawings
The structural representation of Fig. 1 tension and compression rod-type of the present utility model steel and concrete combination beam bridge anti-overturning devices.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
See also shown in Figure 1, tension and compression rod-type steel of the present utility model and concrete combination beam bridge anti-overturning devices, steel and concrete combined structure beam bridge comprise web 8, bearing 9, bent cap 10 and pier stud 11, bent cap 10 is arranged on the pier stud 11, bearing 9 is arranged on the bent cap 10, and web 8 is arranged on the bearing 9.Anti-overturning devices comprises otic placode 1, fork-shaped otic placode 3 and strut and tie 4.Wherein, strut and tie 4 is in the bilateral symmetry setting of bent cap 10.Be provided with composition backing 5 between strut and tie 4 and the bent cap 10.Composition backing 5 connects bent cap 10 by weldering nail 6, and composition backing 5 forms whole by weldering nail 6 and bent cap 10.Strut and tie 4 is provided with stiffening rib with the junction of composition backing 5, and strut and tie 4 is by being provided with stiffening rib and composition backing 5 formation integral body.Otic placode 1 is arranged on the side of web 8, and fork-shaped otic placode 3 is connected by bearing pin 2 with otic placode 1, and an end of strut and tie 4 is fixed on a side of bent cap 10, and the other end of strut and tie 4 connects fork-shaped otic placode 3.
Wherein, strut and tie 4 can also be chain link.Strut and tie can replace with chain link, but prefabrication can effectively relax impact, and simple structure is installed easily.
