Fabricated steel fiber reinforced concrete road connecting structure and road thereof

Abstract

The invention relates to the field of road construction, in particular to a fabricated steel fiber reinforced concrete road connecting structure and a road thereof. The connecting structure comprisesa pre-clamping rod, a clamping sleeve and a locking assembly; the cross section of an inner cavity of the clamping sleeve is of an L-shaped structure with an opening in the top end; an inner cavity ofthe L-shaped clamping sleeve comprises a vertically-arranged guide-in channel and a clamping groove located in the end of the bottom side; the clamping rod is sleeved with the clamping groove in a conformal mode, the transverse outer side face of the clamping rod is provided with a third pressing inclined face, the third pressing inclined face inclines outwards from top to bottom and stretches into the guide-in channel, the locking assembly comprises a locking pressing block and a locking piece, and a fourth pressing inclined face matched with the third pressing inclined face is arranged on the transverse side face of the bottom of the locking pressing block; the connecting strength between fabricated steel fiber reinforced concrete road plate bodies can be effectively improved, the goodintegrity of the road is guaranteed, assembling and disassembling are convenient, replacement is facilitated, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of road construction, in particular to an assembled steel fiber concrete road connection structure and its road. Background technique [0002] Steel fiber reinforced concrete is a new type of multiphase composite material formed by mixing random distributed short steel fibers into ordinary concrete. These randomly distributed steel fibers can effectively prevent the expansion of micro-cracks and the formation of macro-cracks in concrete, significantly improve the tensile, bending, impact and fatigue properties of concrete, and have good ductility; and assembly The steel fiber reinforced concrete road is a concrete structure formed by assembling and connecting steel fiber reinforced concrete prefabricated components as the main force-bearing components. Prefabricated steel fiber reinforced concrete road structure is one of the important directions of road development in my country. It is conducive to the development o...

Problems solved by technology

Compared with the cast-in-place construction method, the prefabricated structure is conducive to green construction, because the prefabricated construction can better meet the requirements of green construction such as land saving, energy saving, material saving, water saving and environmental protection, and reduce the negative impact on the environment, including reducing Noise, prevention of dust, reduction of environmental pollution, clean transportation, reduction of site disturbance, conservation of water, electricity, materials and other resources and energy, especially when prefabricated steel fiber concrete roads are applied to temporary roads, follow the principle of sustainable development; In some prefabricated steel fiber reinforced concrete roads, the connection between road slabs is usually fixed by screw connection or welding, and the resistance stress of screw connection in all directions is inconsistent, which makes the overall connection strength low; while welding fixation is easy to cause welding cracks, The stability is poor, and it is not easy to remove and replace the road slab in the middle
