Description
Technical field
The invention belongs to technical field of bridge engineering, relate to bridge expanssion joint technical field, particularly a kind of bridge expansion joint installation.
Background technology
Bridge, when the ambient parameters such as temperature change, has the longitudinal strain of expanding and shrinking, vertical and horizontal flexural deformation; Under car load, there are length travel and vertical flexural deformation.In order to meet bridge deformation requirement, usually expansion gap device is set between beam-ends or itself and platform are carried on the back, to allow longitudinally, the vertical Free Transform such as bending.Bridge expanssion joint is divided into seamed shrinkage joint and expansion joints without seals.
Conventional expansion gap device is roughly divided into five large classes by mode of transfer force and construction features: dock, steel supporting type, building rubber compound are shearing, modulus supporting type and seamless telescopic.But the problems such as inconvenience, stress performance and poor durability, application life is short are installed in the existence all in various degree of existing highway bridge stretching device.Compared with seamed shrinkage joint, expansion joints without seals, owing to can effectively avoid the problems such as vibrations, spring, has the features such as comfortable safety, cost is low, maintenance is few of driving a vehicle, thus is paid close attention to and apply.
Expansion joints without seals conventional at present arranges one section of bridge floor steel failure district near beam-ends, makes free slippage between reinforcing bar and concrete, realize beam-ends and stretch, but can ftracture in this kind of shrinkage joint under Moment, affect bridge durability.An other class expansion joints without seals adopts rubber or rubber steel plate composite component and bridge floor pitch etc., though such expansion joints without seals structure structure is simple, easy construction, rubber abrasive-resistance is poor, application life is short.
Summary of the invention
The seamless bridge expansion gap device the object of the invention is to propose that a kind of structure is simple, easy construction, life-span are long, having vibration and noise reducing effect concurrently.
For reaching this object, the present invention by the following technical solutions:
A kind of bridge expansion joint installation, comprise fixture and marmem plate that the beam body of bridge expanssion joint both sides is arranged respectively, the two ends of described marmem plate are fixed on described fixture respectively.
As the preferred technical scheme of one, described marmem plate is waveform plate body.
As the preferred technical scheme of one, described fixture is steel plate, and described fixture is embedded in inside concrete in advance when bridge floor is poured into a mould.
As the preferred technical scheme of one, the two ends of described marmem plate are fixed on described fixture respectively by welding.
As the preferred technical scheme of one, described marmem plate is that austenitic steel is made.
As the preferred technical scheme of one, described fixture comprises plate-like body, and the middle part of described plate-like body stretches out formation fixed part, and described fixed part is embedded in inside concrete in advance.
As the preferred technical scheme of one, the quantity of described marmem plate is at least two pieces, at least two pieces of folded settings of described marmem flaggy.
As the preferred technical scheme of one, the surface being positioned at the described marmem plate of the top is plane.
Beneficial effect of the present invention is as follows:
Bridge expansion joint installation provided by the invention utilizes the super elastic characteristics of marmem to carry out damping energy-absorbing, realize the continuous formation of bridge floor, structure be simple, easy construction, economical and practical, and can effectively prevent from jumping car, have vibration and noise reducing effect concurrently, be applicable to small size expanded joint structure.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Embodiment:
The embodiment provides a kind of bridge expansion joint installation, as depicted in figs. 1 and 2, it comprises fixture 1 and marmem plate 2 that the beam body 3 of bridge expanssion joint both sides is arranged respectively, the two ends of marmem plate 2 are fixed on fixture 1 respectively, and the material of marmem plate 2 is preferably austenitic steel.
When bridge floor is subjected to displacement deformation, there is deformation and stretch elongated in marmem plate 2, and when Displacement-deformation disappears, wavy shape memorial alloy plate 2 recovers deformation, and marmem plate 2 can consume certain energy in the process.Bridge expansion joint installation provided by the invention utilizes the super elastic characteristics of marmem to carry out damping energy-absorbing, realize the continuous formation of bridge floor, structure be simple, easy construction, economical and practical, and can effectively prevent from jumping car, have vibration and noise reducing effect concurrently, be applicable to small size expanded joint structure.
In order to strengthen the damping effect of bridge expansion joint installation further, above-mentioned marmem plate 2 is waveform plate body.When the bridge floor of marmem plate 2 both sides produces stretcher strain, wavy shape memorial alloy plate 2 stretches, and when bridge floor produces shrinkage strain, the wavy shape memorial alloy plate 2 still with certain deformability can produce shrinkage strain further.The pre-bending degree of wavy shape memorial alloy plate 2 designs according to bridge floor size, bridge floor load and bridge floor deformation, can meet cushioning effect.
The quantity of marmem plate 2 is preferably at least two pieces, the stacked setting of at least two block-shaped memorial alloy plates 2.When the quantity of marmem plate 2 is at least two pieces, preferably, the marmem plate 2 being positioned at the top is surface plate bodys for plane, to increase the planarization of bridge floor, other marmem plates 2 can select the marmem plate 2 of undulate plate body according to specific needs, to strengthen damping effect.The quantity of marmem plate 2 also can design according to the thickness of pontic, bridge floor load and bridge floor deformation, can meet cushioning effect.
Above-mentioned fixing piece 1 comprises plate-like body 11, and the middle part of plate-like body 11 stretches out and forms fixed part 12, and fixed part 12 is embedded in the inside concrete of the beam body 3 of bridge expanssion joint both sides in advance when bridge floor is poured into a mould.Above-mentioned fixing piece 1 is preferably steel plate and makes, and the two ends of marmem plate 2 are fixed on fixture 1 respectively by welding.Two ends and the two curb girder bodies 3 of marmem plate 2 are fixed, and ensure that the bridge floor deform in same pace above marmem plate 2 and two end carriage bodies.
In addition, it should be noted that, the shape of above-mentioned marmem plate 2 is not limited to above-mentioned situation, and other can meet the shape of damping effect; The shape of above-mentioned fixing piece 1, material are not limited to above-mentioned situation, other any situations that marmem plate 2 can be fixed on the beam body 3 of bridge expanssion joint both sides; Above-mentioned marmem plate 2 is also not limited to above-mentioned situation, other any connected modes that the two ends of marmem plate 2 can be fixed on fixture 1 with the fixed form of fixture 1.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
