Reinforced fracture-resistant road-bridge pavement slab

Abstract

The invention discloses a reinforced fracture-resistant road-bridge pavement slab which comprises a first pavement slab and a second pavement slab. A second steel plate is mounted at the top end of each of the first pavement slab and the second pavement slab, a first concave block, a second concave block and a first inserting plate penetrate two sides of a second inserting plate, the bottom ends of two sides of a first steel plate are connected with the first pavement slab and the second pavement slab, a screw penetrates the first steel plate and the second inserting plate, a bearing is fixedon the front of a first fixing block through a rotating rod, a supporting rod is mounted at the left end of the bearing, a convex block is mounted on the left side of the top end of the supporting rod, and the outer wall of the convex block is connected with a third concave block. Through cooperation of the first concave block and the second concave block, the supporting rod clockwise rotates through the bearing to be buckled with the third concave block to mount a tension spring on the surface of the supporting rod to the end of the second inserting plate, so that probability of danger is lowered, and traffic accidents caused by fracture of the pavement slab are reduced effectively.

Description

technical field [0001] The invention relates to the technical field of road slabs, in particular to a reinforced and anti-fracture road slab for roads and bridges. Background technique [0002] Mechanized road surface operation equipment is a kind of equipment that quickly lays road slabs on muddy roads, sandy land and other places that are inconvenient for vehicles to drive, so that vehicles can drive on the paved road slabs, so the quality of the road slabs directly determines the safety of the vehicle. Traffic capacity, the existing road slab is generally a hinge structure, and the degree of freedom of rotation between each connecting unit is large, which causes the connecting unit to sink when the vehicle is driving, and has unevenly distributed ballast on the ground, which affects the traffic effect of the vehicle , in the prior art, such as the invention patent with application number 201620186486.7, which includes a group of sub-road panels hinged in turn, each sub-ro...

[0002] Mechanized road surface operation equipment is a kind of equipment that quickly lays road slabs on muddy roads, sandy land and other places that are inconvenient for vehicles to drive, so that vehicles can drive on the paved road slabs, so the quality of the road slabs directly determines the safety of the vehicle. Traffic capacity, the existing road slab is generally a hinge structure, and the degree of freedom of rotation between each connecting unit is large, which causes the connecting unit to sink when the vehicle is driving, and has unevenly distributed ballast on the ground, which affects the traffic effect of the vehicle , in the prior art, such as application number 201620186486

The invention patent of 7 includes a group of sub-road panels hinged in turn, each sub-road panel includes a group of basic pavement units spliced ​​together, and the basic pavement unit consists of seven or ten above-mentioned pavement blocks spliced ​​by male buckles and female grooves to form a rectangle. A rectangular basic pavement unit is formed by interlocking hexagonal and trapezoidal pavement blocks, and then several basic pavement units are interconnected to form a sub-pavement panel, and finally several sub-pavement panels are hinged to form a pavement panel. Although this patent is non-slip, it improves the The speed of vehicles, but the connection between the road panels is not stable. If the traffic flow is relatively large, it is easy to break the connection of the road panels during the driving process, which may cause serious traffic accidents when the danger is serious.
