Description
Technical field
The utility model relates to bridge earthquake resistance technical field, specifically, relates to the anti-buckling restrained bracing member in a kind of bridge earthquake resistance.
Background technology
Curvature-prevention support component, as a kind of new structure component, not only can be used as the lateral resistant member of bridge construction or building structure, and can show outstanding energy-dissipating and shock-absorbing performance under geological process.In recent years, anti-bucklingly support in the middle of some large bridge structures or building structure of starting to be applied to China gradually, especially in the area that seismic fortification intensity is higher, can significantly lift bridge girder construction or the functional performance of building structure under seismic loading.But more existing curvature-prevention support component structure more complicated, heavier, simultaneously more inconvenient in maintenance, so can unusual inconvenience in bridge construction.
So, can improve when developing a kind of use that anti-fall under earthquake and other accidental actions of bridge is collapsed, peel ability and energy dissipation capacity, simultaneously light, the easy construction of simple structure, quality, the anti-buckling restrained bracing member that easy to maintenance, security performance is good, just become the problem that insider needs solution badly.
Utility model content
For the problem in correlation technique, the utility model proposes the anti-buckling restrained bracing member in a kind of bridge earthquake resistance, can improve during use that anti-fall under earthquake and other accidental actions of bridge is collapsed, peel ability and energy dissipation capacity, simultaneously light, the easy construction of simple structure, quality, easy to maintenance, security performance good.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
Anti-buckling restrained bracing member in a kind of bridge earthquake resistance, comprise front surrounding casing and back surrounding casing, constraint support is equipped with in described front surrounding casing and described back surrounding casing, the space surrounded between described front surrounding casing and described back surrounding casing defines cross-shaped cavity, be provided with kernel in described cross-shaped cavity to support, wherein, it is constraint surrender section in the middle of described kernel supports, it is without constraint non-compliant section that described kernel supports two ends, and what described kernel supported surrenders between section as to retrain non-compliant section without constraint non-compliant section and constraint.
Further, be fastenedly connected by junction plate between described front surrounding casing and described back surrounding casing.
Further, be provided with in described cross-shaped cavity and support with described kernel the adhesive-less layer matched.
Further, described front surrounding casing or described back surrounding casing side are provided with some hangers.
Further, described front surrounding casing and described back surrounding casing are all in concave shape structure.
The beneficial effects of the utility model: simple structure, quality are light, easy construction, easy to maintenance, security performance good, also improve that anti-fall under earthquake and other accidental actions of bridge is collapsed, peel ability and energy dissipation capacity simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation one of the anti-buckling restrained bracing member in the bridge earthquake resistance according to the utility model embodiment;

Fig. 3 is the sectional view of the anti-buckling restrained bracing member in the bridge earthquake resistance according to the utility model embodiment.
In figure:
1, constraint supports; 2, kernel supports; 21, constraint surrender section; 22, without constraint non-compliant section; 23, non-compliant section is retrained; 3, cross-shaped cavity; 4, adhesive-less layer; 5, hanger; 6, front surrounding casing; 7, back surrounding casing; 8, junction plate.
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, other embodiments all that those of ordinary skill in the art obtain, all belong to the scope of the utility model protection.
As Figure 1-3, anti-buckling restrained bracing member in a kind of bridge earthquake resistance according to embodiment of the present utility model, comprise front surrounding casing 6 and back surrounding casing 7, constraint support 1 is equipped with in described front surrounding casing 6 and described back surrounding casing 7, the space surrounded between described front surrounding casing 6 and described back surrounding casing 7 defines cross-shaped cavity 3, be provided with kernel in described cross-shaped cavity 3 and support 2, wherein, described kernel is constraint surrender section 21 in the middle of supporting 2, described kernel supports 2 two ends for nothing constraint non-compliant section 22, surrendering between section 21 as to retrain non-compliant section 23 without constraint non-compliant section 22 and constraint of described kernel support 2.
In one embodiment, be fastenedly connected by junction plate 8 between described front surrounding casing 6 and described back surrounding casing 7.
In one embodiment, be provided with in described cross-shaped cavity 3 and support 2 adhesive-less layers matched 4 with described kernel.
In one embodiment, described front surrounding casing 6 or described back surrounding casing 7 side are provided with some hangers 5.
In one embodiment, described front surrounding casing 6 and described back surrounding casing 7 are all in concave shape structure.
Conveniently understand technique scheme of the present utility model, below by way of in concrete mode of occupation, technique scheme of the present utility model is described in detail.
When specifically using, when there is earthquake, the constraint supported on 2 of described kernel is surrendered section 21, constraint non-compliant section 23, can well be dissipated the energy produced because of earthquake acted on support arrangement direction without constraint non-compliant section 22, to be consumed energy the interfacial failure that alleviates between bridge member or component damage by self surrender, or even do not produce destruction to prevent bridge collapse, the situation such as bridge floor comes off, component damage occurs.
In sum, by means of technique scheme of the present utility model, the effect of 2 is supported by kernel, effectively raise that anti-fall under earthquake and other accidental actions of bridge is collapsed, peel ability and energy dissipation capacity, simultaneously light, the easy construction of simple structure, quality, easy to maintenance, security performance good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
