Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of road and bridge construction, especially relates to a load-carrying bridge for road and bridge expansion joint construction. BACKGROUND

[0002] The expansion joint of the road and bridge is a structural gap arranged to meet the requirement of the deformation of the bridge deck, and is usually located between two beam ends, between the beam end and the abutment or the hinge position of the bridge. The main function of the expansion joint is to absorb and release the deformation energy of the bridge caused by the temperature change, the shrinkage of the concrete, the creep and the vehicle load, so as to prevent the damage of the bridge structure caused by the excessive deformation.

[0003] During the construction of the expansion joint, the surface layer of the road at the position of the expansion joint is cut and grooved, the filler in the expansion joint is cleaned, the expansion joint steel is welded and positioned, and the flatness of the steel is checked. After the positioning of the steel, the concrete is poured. In the existing construction process, in order to avoid the damage of the expansion joint after construction by external force, if the expansion joint has not reached the design curing strength after pouring, the top surface of the expansion joint is not allowed to pass through the vehicle and other equipment, therefore, the concrete construction vehicle or other equipment for pouring the expansion joint cannot be moved to another expansion joint section to be constructed, which results in that the remaining expansion joints in the road and bridge cannot be continuously constructed, thereby limiting the construction sequence and the construction speed of the expansion joint. SUMMARY

[0004] The utility model aims at providing a load-carrying bridge for road and bridge expansion joint construction, and overcomes the above-mentioned defects of the prior art, which effectively solves the existing problem that the expansion joint cannot be continuously constructed.

[0005] The utility model relates to a load-carrying bridge for road and bridge expansion joint construction, characterized by comprising a pair of supporting beams, a pair of connecting plates is installed at the lower end of the inner side wall of the supporting beam, the inner ends of the opposite two connecting plates are hingedly connected, a pair of L-shaped butt plates is installed at the lower end of the outer side wall of the supporting beam, a through hole is formed in the L-shaped butt plate, and a pair of clamping rods is installed on the bottom wall of the supporting beam.

[0006] Further, a plurality of anti-skid rods are uniformly installed on the top wall of the supporting beam.

[0007] Further, the length of the anti-skid rod is equal to the width of the top wall of the supporting beam.

[0008] Further, the pair of supporting beams are isosceles trapezoidal.

[0009] Further, the width of the pair of clamping rods is equal to the width of the bottom wall of the supporting beam.

[0010] Furthermore, the spacing between the pair of levers is equal to the size of the expansion joint.

[0011] Furthermore, the spacing between the pair of supporting beams is 10cm to 15cm.

[0012] Furthermore, the supporting beam is an I-beam, the anti-slip rod is a threaded steel bar, and the clamping rod is a square steel bar.

[0013] The beneficial effects of this utility model are: by placing the load-bearing bridge on the construction expansion joint, concrete transport vehicles or other equipment can be moved to another expansion joint construction point, thereby realizing continuous construction of several expansion joints, optimizing the construction sequence of expansion joints and improving the construction speed.

[0018] In the diagram, 1 is the supporting beam, 2 is the connecting plate, 3 is the L-shaped butt plate, 4 is the through hole, 5 is the through hole, 6 is the anti-slip rod, and 7 is the expansion joint. Detailed implementation method:

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0020] like Figs. 1 to 4 As shown, a load-bearing bridge for the construction of expansion joints in road bridges includes a pair of supporting beams 1. A pair of connecting plates 2 are installed at the lower end of the inner sidewall of the supporting beams 1, and the inner ends of the two opposing connecting plates 2 are hinged together. A pair of L-shaped butt plates 3 are installed at the lower end of the outer sidewall of the supporting beams 1, and through holes 4 are opened on the L-shaped butt plates 3. A pair of clamping rods 5 are installed on the bottom wall of the supporting beams 1. Several anti-slip rods 6 are evenly installed on the top wall of the supporting beams 1. The length of the anti-slip rods 6 is equal to the width of the top wall of the supporting beams 1. The pair of supporting beams 1 are in the shape of an isosceles trapezoid. The width of the pair of clamping rods 5 is equal to the width of the bottom wall of the supporting beams 1. The spacing of the pair of clamping rods 5 is equal to the size of the expansion joint 7. The spacing of the pair of supporting beams 1 is 10cm to 15cm. The supporting beams 1 are I-beams, the anti-slip rods 6 are threaded steel, and the clamping rods 5 are square steel.

[0021] Specifically, by placing the load-bearing bridge on the construction joint, the construction vehicle or other equipment can be moved to another construction point of the joint, thereby realizing continuous construction operation of several joints, optimizing the construction sequence of the joint and improving the construction speed.

[0022] In actual use, a pair of the beams 1 is placed across the construction joint 7, so that the small concrete transport bucket or other small equipment can pass over the joint 7 when the joint 7 does not reach the designed curing strength, and the construction vehicle can smoothly drive to the construction point of another joint 7; if a large vehicle can be placed with another pair of the beams 1, it can safely pass through; when the two L-shaped abutting plates 3 are attached, the bolt is inserted into the through hole 4 to connect and fix them, so that several groups of the beams 1 can be placed in parallel on the joint 7, thereby widening the passing area of the load-bearing bridge; during the use of the load-bearing bridge, a pair of the clamping rods 5 is installed on the bottom wall of the beam 1 to prevent the beam 1 from shaking in the joint 7, thereby further improving the safety and stability of the use; when the concrete transport vehicle or other equipment passes over the load-bearing bridge, the several threaded steel anti-skid rods 6 can improve the friction with the tire, so that the passing is more safe and stable; when the load-bearing bridge is used up, under the hinged connection of the inner ends of the two connecting plates 2, a pair of the beams 1 can be folded together, which not only facilitates the rapid transportation to the next construction site, but also reduces the storage volume.

[0023] The above is only the preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
