Abstract
The utility model relates to a temporary highway bailey truss lower-noise steel bridge, and belongs to the technical field of highway engineering. The temporary highway bailey truss lower-noise steel bridge comprises a steel transverse beam and steel bridge panels, and is characterized in that a rubber gasket is arranged between the steel transverse beam and each steel bridge panel of the temporary bailey truss steel bridge, and the steel bridge panels in blocks are fixedly connected mutually to form a whole panel structure. The temporary highway bailey truss lower-noise steel bridge has the advantages that the bridge is simple in structure, convenient to construct and good in integrality, deformation of the bridge panels is reduced, partial vibration is reduced, horizontal collision between every two panels is reduced, the service life is long and the dryness reducing effect is obvious.
Description
Technical field
The utility model belongs to the highway engineering technical field, particularly relates to a kind of highway Bailey bracket low noise steel suspension bridge.
Background technology
At present, large span highway Bailey bracket steel suspension bridge is flexible large, and under Under Dynamic Load, amount of deflection is large, and steel bridge deck directly contacts nothing connection between the bridge deck with the i iron crossbeam.Under the effect of the dynamic loads such as vehicle, Steel Bridge Deck directly contacts with gooseneck and the friction that produces and collision sound, between steel facing the horizontal direction collision serious, cause distortion.Because collision, spring, vibrations, friction etc. produce very large noise, both affected bridge application life, also cause the technical problems such as the dry sound pollution of environment.
Summary of the invention
The utility model provides a kind of highway Bailey bracket low noise steel suspension bridge for solving the technical problem that exists in the known technology.
The purpose of this utility model provide a kind of have simple in structure, easy construction, good integrity reduces the bridge deck distortion, reduces local vibrations, reduces between plate the level punching and bumps, the highway Bailey bracket low noise steel suspension bridge of the characteristics such as dry successful falls in long service life.
The utility model operating principle: between crossbeam and bridge floor, rubber sheet gasket is set, can cushions the power that crossbeam is passed on top, reduce to a certain extent vibrations; Friction and the collision sound of also having avoided Steel Bridge Deck to produce with direct contact of gooseneck.
Between steel bridge deck and crossbeam, adopt reinforced screw rod, can improve the durability of bolt, avoid the steel suspension bridge repeatedly shake with horizontal impact under and loosening too early, thereby reduce bridge deck under Under Dynamic Load, to beat and the noise that produces.
Steel bridge deck is welded into integral body, has increased the globality of bridge floor, reduce local vibrations and the loosening phenomenon of upspringing occurs, also reduced the impact in the horizontal direction between plate, thus the noise that reduces.
The technical scheme that the utility model highway Bailey bracket low noise steel suspension bridge is taked is:
A kind of highway Bailey bracket low noise steel suspension bridge comprises gooseneck and steel bridge deck, is characterized in: be provided with rubber sheet gasket between the gooseneck of Bailey bracket steel suspension bridge and steel bridge deck, be fixedly connected with between the piecemeal steel bridge deck, consist of the integral panels structure.
The utility model highway Bailey bracket low noise steel suspension bridge can also adopt following technical scheme:
Described highway Bailey bracket low noise steel suspension bridge, be characterized in: rubber sheet gasket is the rectangle sheet, with wide elongated, the tiling setting of gooseneck.
Described highway Bailey bracket low noise steel suspension bridge, be characterized in: rubber sheet gasket is equipped with screw rod at bridge floor plate hole position correspondence position prepared screw-bolt hole between steel bridge deck and the crossbeam, and the bolt between steel bridge deck and the crossbeam is fixed together rubber sheet gasket.
Described highway Bailey bracket low noise steel suspension bridge, be characterized in: the mode that is fixedly connected with between the piecemeal steel bridge deck is welded construction.
Described highway Bailey bracket low noise steel suspension bridge is characterized in: welded construction is the elongated round bar that arranges in groove between the bridge deck and the space between the piecemeal steel bridge deck, elongated two-sided welding between round bar and the steel bridge deck.
Advantage and the good effect that the utlity model has are:
Highway Bailey bracket low noise steel suspension bridge is owing to adopted the brand-new technical scheme of the utility model, compared with prior art, bolt between the utility model steel bridge deck and the crossbeam is fixed rubber sheet gasket, thereby avoid steel bridge deck directly to contact with crossbeam, form buffering, the generation of noise reduction on the sound source.Bridge deck form integral body, increase the globality of bridge floor, reduce the bridge deck distortion, reduce local vibrations and the loosening phenomenon of upspringing occurs, and have also reduced the impact in the horizontal direction between plate, thus the noise that reduces.

The specific embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
A kind of highway Bailey bracket low noise steel suspension bridge, 1 of the gooseneck 6 of Bailey bracket steel suspension bridge and steel bridge deck are provided with rubber sheet gasket, and rubber sheet gasket 3 is the rectangle sheet, with gooseneck 5 wide elongated, tiling settings.Rubber sheet gasket 3 is equipped with screw rod at bridge floor plate hole position 6 correspondence position prepared screw-bolt holes between steel bridge deck 1 and the gooseneck 5, and the bolt between steel bridge deck 1 and the gooseneck 5 is fixed together rubber sheet gasket 3.
1 of piecemeal steel bridge deck is fixedly connected with, and consists of the integral panels structure.Welded construction is the elongated round bar that arranges in groove between the bridge deck and the space between the piecemeal steel bridge deck, elongated two-sided welding between round bar and the steel bridge deck 1.
The concrete structure of present embodiment and implementation process:
Bailey bracket steel suspension bridge has been installed the noise reduction setting, the noise reduction measure of taking.Mainly aspect three:
1, on the gooseneck of Bailey bracket steel suspension bridge rubber sheet gasket is set.Rubber sheet gasket is rectangular tab, arranges, and opens prepared screw-bolt hole at bridge floor plate hole position correspondence position with wide elongated, the tiling of gooseneck.Bolt between steel bridge deck and the crossbeam is fixed rubber sheet gasket, thereby avoids steel bridge deck directly to contact with crossbeam, forms buffering, the generation of noise reduction on the sound source.Before laying the foreign material on the gooseneck are cleaned out, be convenient to rubber sheet gasket and its applying is tight.
2, between steel bridge deck and crossbeam, adopt reinforced screw rod.After rubber sheet gasket is laid and is finished, according to the bolt hole position, the corresponding steel bridge deck of installing.Adopt reinforced screw rod to be connected between bridge deck and the crossbeam.
3, the piecemeal steel bridge deck is welded into integral body.After the steel bridge deck installation, the elongated round bar that arranges in the groove between bridge deck and the space, and carry out elongated two-sided welding with between itself and the steel bridge deck, make bridge deck form integral body, increase the globality of bridge floor, reduce the bridge deck distortion, the generation of noise reduction.
