Problems solved by technology

Due to the use of laminated FRP materials, this technical solution has the characteristics of corrosion resistance and light weight. At the same time, the L-shaped plate can realize rigid connection and effectively prevent mud (sand), but the upper surface of the connected road slab is flat and the lower part protrudes Most of the pavement is suspended and the lower part of the connector protrudes. For soil areas with poor passability and high bearing capacity (such as dehydrated clay areas, hard pavement sidewalk areas, etc.), it is easy to cause damage to the pavement. At the same time, its connection The threaded connection of the device is easy to be stuck by sand and other materials, and it cannot be quickly disassembled.
In addition, due to its design and structure, the design thickness of the board is relatively thin, usually about 9mm, and double layers cannot be laid to improve the bearing capacity, which cannot meet the application of vehicles in soft soil areas.

Abstract

The invention belongs to road equipments used in the traffic guarantee field, in particular to a connecting device of a fast-assembling light road slab, which is matched with the road slab in order to meet the access of vehicles in the areas with disadvantageous geologies, such as sludge, sand beach and the like. Mounting holes are arranged on the surface of the light road slab; connecting elements are connected between corresponding mounting holes on adjacent road slabs by crossing; embedded sleeves are fixed on the inner walls of the mounting holes; the connecting element comprises a shell which is in sliding fit with the inner wall of the embedded sleeve, has a bulging top and is jointed with the upper end of an inner hole of the embedded sleeve, a rotating shaft which is arranged in acavity of the shell and a pallet fixed on the bottom end of the rotating shaft; wherein, the periphery of the rotating shaft is in running or clearance fit with the cavity of the shell; an axial positioning mechanism is arranged between the outer surface of the rotating shaft and the inner wall of the shell; a spanner is connected on the top of the rotating shaft. The connecting device of the fast-assembling light road slab solves the problem in the prior art that connecting devices can not realize fast assembling and disassembling and have poor reusability, and has the advantages of fast assembling and disassembling, convenient manual operation and high working reliability, etc.

Description

Technical field [0001] The invention belongs to pavement equipment used in the field of traffic security, in particular to a quick-installed light-weight pavement panel connecting device for pavement panels suitable for vehicles to pass through in muddy, sandy and other unfavorable geological areas. Background technique [0002] Especially with the improvement of military traffic readiness requirements of modern national defense equipment and the increasingly obvious requirements for emergency support in response to unpredictable natural disasters, countries around the world are actively developing new standard road equipment. Utility model patent 200520012913.1 discloses a moving and fast paving engineering pavement panel, the technical solution of which is to use square plastic panels with connecting edges around them, and connect and fix different panels through bolts, wherein two adjacent connecting edges are made of The female connecting hole and the fastening hole are ...
