Abstract
The utility model discloses a truss structure energy-absorbing type anti-ship-collision device for a bridge, comprising supports fixed on a bridge pier and an anti-collision crossbeam disposed on the supports, the flanges of the supports are provided with some notches, reducing cross section; impact force of the ship is transmitted to the supports via the crossbeam; since the supports are obliquely fixed at the bridge pier, the impact force of the ship generates axial force and bending moment for the supports; the reduced parts of the cross sections of the supports firstly deform, forming plastic hinges for absorbing energy; via loosening bolts, the damaged parts can be detached, and a new member can be replaced; the truss structure energy-absorbing type anti-ship-collision device for a bridge is advantaged by convenient installation and maintenance, easy replacing, simple structure, and low cost.
Description
Technical field
The utility model relates to the anti-ship collision device of a kind of bridge, particularly a kind of trussed construction, the anti-ship collision device of energy-absorption type bridge.
Background technology
The pier anticollision measure of bridge is the important means that ensures bridge security, and main hazard derives from the ship collision bridge.The bridge-collision-avoidance measure prevents the damage of boats and ships to bridge, mainly comprises and the direct-connected anti-ship collision device of bridge pier and take over control the ship collision device.Between take over control the ship collision device and be included in and structures such as man-made island, dolphin be set around the bridge pier, can solve the pier anticollision problem preferably.But exist floor space big, can only be arranged on the more shallow and basic good position, riverbed of the depth of water, be not suitable for that use in area less waters in river course, the more high shortcoming of cost.Direct-connected anti-ship collision device is set directly at bridge pier to be protected bridge pier, comprises elastic deformation structure, plastic strain buffer structure etc.At present, main device has anti-collision jacket structure or anticollision box structure, protects bridge pier through the supporting deformation or the damage that are provided with in crashproof shell or the crashproof shell.There is the shortcoming that installing and replacing is loaded down with trivial details, cost is expensive in these devices.
Therefore, need a kind of novel anti-ship collision device of research and development, not only can well protect bridge pier, and easy to installation and maintenance, be prone to change, simple in structure, device that cost is low.
The utility model content
In view of this, the purpose of the utility model provides a kind of replacing easy to installation and maintenance, easy, the anti-ship collision device of trussed construction energy-absorption type bridge simple in structure, that cost is low.
The purpose of the utility model is to realize through following technical scheme: a kind of trussed construction energy-absorption type bridge is prevented the ship collision device, comprises being fixed on the support on the bridge pier and being arranged on the crashproof crossbeam in the support, and the said support edge of a wing is provided with the part breach, reduces the cross section.
Further, form sharp angle between the axis of said support and the bridge pier surface;
Further, said support two ends section area reduces, and when hit by ship, forms plastic hinge;
Further, i-shaped beams is adopted in said support;
Further, said crashproof crossbeam adopts i-shaped beams;
Further, adopt bolt to be connected between said support and the bridge pier, be fixedly connected through bolt or welding manner between support and the crossbeam.
The beneficial effect of the utility model: ship impact force passes to support through crossbeam; Owing to support the edge of a wing part breach minimizing cross section is set, ship impact force produces axle power and moment of flexure to supporting; Supporting section reduces at first distortion of part, forms plastic hinge and absorbs energy; Through the absent-mindedness bolt, dismounting damage part is changed new structural member; Easy to installation and maintenance, be prone to change, simple in structure, cost is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A portion enlarged drawing among Fig. 1;
Fig. 3 be among Fig. 1 along M-M to sectional view.
The specific embodiment
Fig. 1 is the structural representation of the utility model; Fig. 2 is the A portion enlarged drawing among Fig. 1; Fig. 3 be among Fig. 1 along M-M to sectional view.As shown in the figure: the trussed construction energy-absorption type bridge of the utility model is prevented the ship collision device, comprises the support 2 that is fixed on the bridge pier 1 and is arranged on the crashproof crossbeam 3 in the support, and said support 2 edges of a wing are provided with part breach 4, reduce the cross section.
The trussed construction energy-absorption type bridge of present embodiment is prevented the ship collision device, is made up of with crashproof crossbeam 3 support 2 that is fixed on the bridge pier 1.Support 2 and be fixed by bolts to bridge pier, and and abutment surface between the certain sharp angle of formation.Support 2 two ends ad-hoc location minimizing section area (with reference to figure 2), plastic hinge is set.When the ship collision bridge, there is the plastic hinge distortion to absorb the Impact energy buffering percussive force, bridge pier is shielded.
Crossbeam supports 2 to each and is connected to form one, and impact is distributed to a support, prevents boats and ships local distortion simultaneously.
Support 2 is all adopted i shaped steel with crashproof crossbeam 3, is convenient to manufacturing or buying, connects, processes.Support 2 and be fixed by bolts to bridge pier, support 2 and crashproof crossbeam 3 between with bolt or be welded to connect, be convenient to installation and removal.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
