Abstract
The invention discloses a buckling-restrained brace structure for a bridge. The buckling-restrained brace structure comprises a core plate, clearance supporting plates, buckling-restrained restraining plates, sliding bars, rubber sealing plates, high-strength bolts and nuts, wherein the core plate is designed to be cross-shaped; the four L-shaped buckling-restrained restraining plates surround the four sides of the symmetrically cross-shaped core plate; the sliding bars used for reducing the frictional resistance are arranged between the buckling-restrained restraining plates and the core plate; a clearance between two adjacent buckling-restrained restraining plates is filled with one clearance supporting plate; the rubber sealing plates are arranged between the buckling-restrained restraining plates and the clearance supporting plates; and two adjacent buckling-restrained restraining plates, the clearance supporting plates and the rubber sealing plates are connected for fixation through the high-strength bolts and the nuts. The buckling-restrained brace structure for the bridge is simple and reliable, is good in damping and energy consumption performances, convenient to disassemble, and low in maintenance and utilization cost.
Description
Technical field
The present invention relates to bridge technology field, be specifically a kind of bridge buckling-resistant support structure。
Background technology
For steel structure truss bridge, steel construction arch bridge, under severe earthquake action, the component of main structure can produce bigger internal force。For preventing the load that component bears from exceeding its bearing capacity, it is necessary to part supported design is become anti-buckling support。Under geological process, anti-buckling support yield deformation, consume portion of energy, reach the purpose of protection bridge main body structure。
At present, anti-buckling support widely uses in construction steel structure, and structure is varied, but principle is identical, is all utilize the metal material surrender catabiotic principle of power consumption。
Additionally, the anti-buckling support applied in the market, mostly cannot dismantle to check internal central layer behaviour in service, cause that user cannot grasp the service condition of product in time, even internal central layer has destroyed and all cannot be found in time, lose the use value of product, time serious, affect the normal usage function of bridge。
Summary of the invention
In view of the above deficiency of prior art, it is an object of the invention to provide a kind of simple and reliable for structure at this, damping energy-dissipating property is excellent, convenient disassembly, safeguards the bridge buckling-resistant support structure that use cost is low。
It is an object of the invention to by following means realization: a kind of bridge buckling-resistant support structure, there is the central layer 1 of axially symmetric cross shape structure；Four anti-buckling restraining plates of L shape are enclosed in four side recesses of symmetrical cross shape central layer；The slider bar 4 reducing frictional resistance it is equipped with between the binding face of anti-buckling restraining plate and central layer 1；The anti-buckling constraint inter-plate gap of adjacent two pieces is clogged by gap gripper shoe 3；Rubber gasket sheet 2 it is equipped with between anti-buckling restraining plate and gap gripper shoe；High-strength bolt is coupled fastening by nut together through the anti-buckling restraining plate of adjacent two pieces and the gap gripper shoe being sandwiched there between, rubber gasket sheet。A kind of bridge buckling-resistant support structure of structure。
The beneficial effects of the present invention is: central layer is designed to symmetrical cross shape, it is possible to maximally utilise the surrender energy-dissipating property of material；Central layer periphery adopts the anti-buckling restraining plate of four L shape of bolt to surround, and can effectively prevent the extrusion after central layer yield deformation on the one hand, facilitate dissembling inspection to safeguard on the other hand；The slider bar mediate contact adopting tetrafluoro sliding material to make between central layer and anti-buckling restraining plate, can effectively reduce the frictional resistance directly contacted between metallic plate with metallic plate, makes to use state to be closer to design calculation result really；It is wrapped in the anti-buckling restraining plate around central layer and gap gripper shoe adopts rubber slab to seal, it is prevented that rainwater or other foreign material enter internal corrosion central layer。
Accompanying drawing explanation
Fig. 1 is the installation diagram of embodiment of the present invention supporting construction。
Fig. 2 is the overall appearance figure of embodiment of the present invention supporting construction。
In figure: 1 central layer, 2 rubber gasket sheets, 3 gap gripper shoes, 4 slider bars, 5 anti-buckling restraining plates, 6 high-strength bolts, 7 nuts, 8 reinforcements support。
Detailed description of the invention
Below in conjunction with accompanying drawing 1, patent of the present invention is described in detail。
Bridge buckling-resistant support structure of the present invention, as shown in Figure 1: include central layer 1, rubber gasket sheet 2, gap gripper shoe 3, slider bar 4, anti-buckling restraining plate 5, high-strength bolt 6, nut 7。Central layer 1 is designed to symmetrical cross shape, and four anti-buckling restraining plates 5 of L shape are enclosed in four sides of symmetrical cross shape central layer 1；The slider bar 4 reducing frictional force it is provided with between anti-buckling restraining plate 5 and central layer 1；5 gaps of the anti-buckling restraining plate of adjacent two pieces are clogged by gap gripper shoe 3；It is provided with rubber gasket sheet 2 between anti-buckling restraining plate 5 and gap gripper shoe 3；The anti-buckling restraining plate 5 of adjacent two pieces is connected and fixed by high-strength bolt 6, nut 7 together with gap gripper shoe 3, rubber gasket sheet 2。
Claims (2)
