Description
Technical Field
The invention relates to the technical field of bridge construction, in particular to a seam crossing vehicle passing device which is convenient for vehicles to normally pass on a bridge during the construction of a bridge expansion joint.
Background
The beam body of most bridges is formed by connecting a plurality of beam sections, and expansion joints are arranged between the mutually connected beam sections. When the expansion joint is constructed, the groove needs to be opened, the concrete for the expansion joint needs to be poured, the concrete needs a certain curing period after being poured to bear the load, and the curing period is long. In general, in order to protect the expansion joint structure, vehicles cannot pass through the bridge during the construction period and the maintenance period of the expansion joint, so that the transportation of materials and equipment in other processes of bridge construction is influenced, and the construction period is prolonged.
Disclosure of Invention
The invention aims to provide a gap-crossing vehicle-passing device for a bridge expansion joint in the construction period, which facilitates the passing of vehicles on a bridge on the premise of not influencing the construction and maintenance of the expansion joint.
The technical scheme of the invention is as follows:
the utility model provides a bridge expansion joint construction period stride seam and lead to car device which characterized in that: the bridge expansion joint comprises a seam crossing main beam, wherein base plates with certain thicknesses are welded on the bottom surfaces of two ends of the seam crossing main beam respectively, and the distance between the two base plates is greater than the width of a bridge expansion joint; the two ends of the seam crossing main beam are respectively provided with a ramp beam, the ramp beam comprises a horizontal bottom surface, a vertical end surface and a slope surface, the bottom surface of the ramp beam is flush with the bottom surface of the base plate at the bottom of the seam crossing main beam, the ramp beam is welded with the end part of the seam crossing main beam, and the height of the end surface of the ramp beam is not higher than that of the seam crossing main beam.
The invention has the advantages of simple material selection, convenient installation and movement, capability of ensuring that vehicles normally pass on the bridge during construction and maintenance of the expansion joint, no influence on concrete maintenance of the expansion joint, low cost and high comprehensive benefit.

FIG. 3 is a schematic cross-sectional view of the II-II ramp beam of FIG. 1.
Detailed Description
As shown in fig. 1, 2 and 3, the invention comprises a main girder 1 with a span joint, wherein base plates 2 with certain thickness are respectively welded on the bottom surfaces of two ends of the main girder with the span joint, and the distance between the two base plates is greater than the width of a bridge expansion joint; and two ends of the seam crossing main beam are respectively provided with a ramp beam 3, each ramp beam comprises a horizontal bottom surface, a vertical end surface and a slope surface, the bottom surface of each ramp beam is flush with the bottom surface of the base plate at the bottom of the seam crossing main beam, the ramp beams 3 are welded with the end parts of the seam crossing main beams 1, and the height of the end surfaces of the ramp beams is not higher than that of the seam crossing main beams.
When the invention is implemented, the invention can be made of I-shaped steel, steel plates and reinforcing steel bars. The seam crossing main beam 1 comprises 3 longitudinal beams which are arranged in parallel and have certain intervals, wherein the longitudinal beam positioned in the middle longitudinal beam adopts double-spliced I-shaped steel, the longitudinal beams on two sides adopt single I-shaped steel, transverse connecting ribs 4 are welded between lower flange plates of adjacent I-shaped steel longitudinal beams at certain intervals, the top surfaces of the 3 longitudinal beams are welded with top plates 5, and the two ends of the bottom surfaces are welded with backing plates 2; the ramp beam 3 comprises 3 ramp beams which are respectively opposite to the end parts of longitudinal beams of the seam crossing main beams, wherein the ramp beam positioned in the middle adopts double-spliced I-shaped steel, the ramp beams on two sides adopt single I-shaped steel, an upper flange plate is cut off along the longitudinal diagonal angle of each ramp beam I-shaped steel to form a bevel edge, and a panel 6 is welded on the bevel edge of each ramp beam I-shaped steel to form a slope surface; and each sloping beam and the end part of the longitudinal beam of the seam crossing main beam opposite to the sloping beam are welded by adopting a double-faced steel plate 7.
The thickness of the cushion plate is at least 1cm larger than the maximum deformation of the I-shaped steel longitudinal beam, so that the I-shaped steel can still keep at least 1cm clear distance from the concrete of the expansion joint when the I-shaped steel deforms maximally.
The lower end and the upper end of the slope surface are respectively welded with a transverse buffer steel bar 8, so that the height difference between the slope surface and the bridge surface and between the slope surface and the top surface of the seam-crossing main beam can be reduced, and when a vehicle passes, the tire can be protected and the vehicle is convenient to pass.
When the bridge expansion joint crossing device is used, the two cross-joint vehicle passing devices cross two sides of a bridge expansion joint according to the distance between wheels, the rubber pads are paved at the bottom of the base plate, and vehicles run over the cross-joint vehicle passing devices when passing through the expansion joint, so that the stability of driving can be ensured, and the concrete of the expansion joint is prevented from being damaged.
