Abstract
The utility model relates to a simple and easy board -like expansion joint device for little span bridge. The device mainly includes pre -buried two angle steel in expansion joint top both sides to the seam of striding that reaches on two angle steel is lapped. The apron adopts the hinge of hinge form to connect with the angle steel of one side, and the top surface that the opposite side angle steel can be followed to the other end slides. The utility model discloses it is more reliable with being connected of angle steel to enable the apron, and the simple and easy expansion joint device of conventionality receives car impact and easily ftractures. The utility model discloses conveniently open the maintenance when filling in debris in the seam. And in apron wearing and tearing back, can conveniently change the apron. Reduced on -the -spot welding jobs in the maintenance construction, also reduced to make the construction quick, high -efficient with the maintenance to the influence of steel material with to the burn of below concrete.
Description
Technical field
This utility model relates to a kind of simple and easy board-like expansion gap device for little span bridge, belongs to science of bridge building field.
Background technology
Retractor device is arranged on beam-ends, and the impact changed by bridge deck temperature and the effect of vehicular load be continuous dilatation frequently, and very easily damages.Expansion joint not only affects the comfortableness of driving, oozes and it would furthermore be possible to cause under water, and then cause the aging of agent structure, the peeling of bridge pier (platform), corrosion and bearing after damaging.Traditional simple and easy board-like expansion gap device adopts the mode welding steel deck-plate on angle steel, it is necessary to welding job amount bigger.A certain partial destruction or need in cleaning expansion joint foreign body time, maintenance construction is just inconvenient.After steel deck-plate abrasion, change also inconvenient, angle steel and steel deck-plate can be caused damage when separating, cause the waste of material, Site Welding also easily affect steel and under concrete material.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of simple and easy board-like expansion gap device for little span bridge.
The purpose of this utility model can be achieved through the following technical solutions.This utility model relates to two angle steel mainly including being embedded in both sides, top, expansion joint, and on two angle steel across seam cover plate, it is welded with bar dowel section inside two angle steel, it is characterized in that being hinged of the cover plate angle steel employing hinge shape with side, the other end can slide along the end face of opposite side angle steel.After casting concrete is installed, on angle steel, the bar dowel section of welding plays anchorage effect.
Further, the hinge structure of hinge shape is by the diverse location at the length direction along expansion gap device, intersect on angle steel end and cover plate, alternately weld steel bushing, steel bushing hop count on angle steel is at least three, steel bushing hop count on cover plate is also at least three, penetrating round steel bar during installation in steel bushing, all of steel bushing is same specification.Material is thus formed being hinged between cover plate and angle steel.
Further, each expansion gap device has multistage to penetrate the rod iron of steel bushing section, and it is rectangle that an end of every section of rod iron is processed to cross section, and every section of rod iron, at least across three steel bushings, so plays fixation.Clamp when the rectangular end portions of rod iron latch is easily installed and removes.
Further, in the gap of adjacent two steel bushings of this expansion gap device, in steel deck-plate plane, is welded with little steel plate strip or lengths of rebar to spanning side.So installing and after casting concrete, steel deck-plate can fixed, not easily rotate under External Force Acting or open, it is possible to avoiding producing at vehicular impact lower cover vibration and whomp.
Further, filling up anticorrosion oils and fats in rod iron latch and the gap of steel bushing section, this is for anticorrosion, and is easy to when keeping in repair to extract rod iron latch.
It addition, the expansion gap device in this utility model can adopt rustless steel to manufacture.
Desirable about 10 centimeters of the thickness of the steel deck-plate in this utility model.Angle steel model is determined according to actual traffic amount, and considers supporting with the steel bushing welded.Anchor rib quantity on angle steel is determined according to actual traffic amount, is advisable less than 20 centimeters with spacing.Steel plate and hinge rotating shaft required for this utility model are high strength steel and make.
This utility model can make the connection of cover plate and angle steel more reliable, and the Simple telescopic of routine seam device to be subject to vehicular impact easy to crack.This utility model is easy to open maintenance when filling in foreign material in seam.And after cover plate weares and teares, it is convenient to change cover plate.Maintenance construction decreases Site Welding operation, also reduces the impact on steel material and the burn to lower concrete, make construction and keep in repair more rapid, efficient.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
Structural representation in the present embodiment is as it is shown in figure 1, be mainly made up of angle steel (1) and cover plate (2).Two angle steel (1) lay respectively at the top of both sides, expansion joint, and one end of cover plate (2) is cut with scissors (3) with an angle steel (1) by hinge-type and is connected, and the other end is positioned on the angle steel upper surface of expansion joint opposite side, can along the upper surface slide of angle steel.The inner side of angle steel (1) is welded with anchor rib (4), after being cast in when expansion gap device is installed in pouring concrete (5), plays the effect of anchoring angle steel.Anchor rib (4) spacing 20 centimeters, the reinforcing bar adopting nominal diameter to be 12 millimeters.The end face of cover plate (2) is consistent with top course (6) upper surface.Beam body concrete (7) top is the space reserved for installing expansion gap device, can reserve or scene cuts out from beam end when beam prefabricated.
The structure detail of hinge-type hinge (3) in the present embodiment is shown in Fig. 2.Cut with scissors the expansion joint length direction of (3) position along hinge-type, interleaved on cover plate (2) and angle steel (1), weld steel bushing (8).By being inserted into rod iron latch (9) three adjacent steel bushings (8), form hinge-type hinge (3).The shape of rod iron latch (9) is shown in figure tri-, and front end comes to a point gradually, it is simple to penetrate, and rectangular cross section is made in rear end, it is simple to clamp with instrument when installing and remove.
Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, the change made in essential scope of the present utility model of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
