Abstract
The utility model discloses a kind of prefabricated reinforced concrete roadbed, including load-bearing metalling, bearing building block layer, pregroove reinforcing bar framework, tiling reinforcing bar, concrete lift；Along roadbed extending direction, and form the parallel load-bearing metalling of twice by spacing of width of subgrade, correspond to pile up along roadbed extending direction on load-bearing metalling described in twice and be provided with twice bearing building block layer, supporting pregroove reinforcing bar framework is embedded with the concave inward structure formed between bearing building block layer described in twice, concrete lift is filled with the sunken inside structure of the pregroove reinforcing bar framework；Inside the concrete lift, tiling reinforcing bar is provided with perpendicular to roadbed extending direction spacing is horizontally-parallel.The utility model provides a kind of prefabricated reinforced concrete roadbed, and construction efficiency is higher, sturdy and durable, has enough erosion resistibilities and larger rigidity, and non-deformability is strong, solid, smooth, good integrity.
Description
Technical field
The utility model belongs to road construction correlative technology field.
Background technology
Material as Portland Cement Concrete Surface Course includes normal concrete, armored concrete, continuous reinforcement concrete, steel fibre
Tie up concrete, grinding coagulation soil etc..In highways and streets and airfield pavement, China uses to be most widely existing at present
The Common Concrete Pavement that field pours, this kind of concrete road surface does not configure in addition to seaming zone and subrange (edge or corner)
Reinforcing bar, the opposite effect that cannot be maximum of service life.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of precast reinforced coagulation
Dirt road base, construction efficiency is higher, sturdy and durable, has enough erosion resistibilities and larger rigidity, and non-deformability is strong,
Solid, smooth, good integrity.
Technical solution：To achieve the above object, the technical solution of the utility model is as follows：
Prefabricated reinforced concrete roadbed, including load-bearing metalling, bearing building block layer, pregroove reinforcing bar framework, tiling steel
Muscle, concrete lift；The parallel load-bearing metalling of twice is formed along roadbed extending direction, and using width of subgrade as spacing, two
Correspond to pile up along roadbed extending direction on load-bearing metalling described in road and be provided with twice bearing building block layer, bearing building block described in twice
Supporting pregroove reinforcing bar framework, the indent of the pregroove reinforcing bar framework are embedded with the concave inward structure formed between layer
Fall into structure and be filled with concrete lift；It is laterally flat perpendicular to roadbed extending direction spacing inside the concrete lift
Row is provided with tiling reinforcing bar.
Further, the bottom both ends of the pregroove reinforcing bar framework are arranged in pairs along the distribution of roadbed extending direction
Cone-shaped steel bar column.
Further, it is also filled with broken reinforcing bar in the sunken inside structure of the pregroove reinforcing bar framework.
Beneficial effect：The utility model provides a kind of prefabricated reinforced concrete roadbed, and construction efficiency is higher, sturdy and durable,
With enough erosion resistibilities and larger rigidity, and non-deformability is strong, solid, smooth, good integrity.
Brief description of the drawings
Attached drawing 1 is the structure diagram of the utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Such as attached drawing 1, prefabricated reinforced concrete roadbed, including load-bearing metalling 1, bearing building block layer 2, pregroove reinforced frame
Structure 3, tiling reinforcing bar 4, concrete lift 7；Along roadbed extending direction, and form using width of subgrade as spacing that twice are parallel holds
Weight metalling 1, piles up along roadbed extending direction correspondence on load-bearing metalling 1 described in twice and is provided with twice bearing building block layer 2, and two
Supporting pregroove reinforcing bar framework 3, the pregroove marks are embedded with the concave inward structure formed between bearing building block layer 2 described in road
Concrete lift 7 is filled with the sunken inside structure of shape reinforcing bar framework 3；Inside the concrete lift 7, perpendicular to roadbed
Extending direction spacing is horizontally-parallel to be provided with tiling reinforcing bar 4.By the pregroove reinforcing bar framework 3 of prefabrication, road is realized
Construction be reduced to：A) rubble is buried；B) building block layer is built；C) pregroove reinforcing bar framework, tiling reinforcing bar 4 and broken reinforcing bar are placed；
D) casting concrete；The improvement of said structure can realize that road construction efficiency is higher.
The bottom both ends of the pregroove reinforcing bar framework 3 are arranged in pairs the cone-shaped steel being distributed along roadbed extending direction
Muscle column 5.The enough erosion resistibilities and larger rigidity, non-deformability for adding concrete lift greatly enhance.
Broken reinforcing bar is also filled with the sunken inside structure of the pregroove reinforcing bar framework 3.Building rubbish can be made full use of
Rubbish, and can be further so that the roadbed of road reaches erosion resistibility and larger rigidity, non-deformability increases
By force.
To sum up, the utility model construction efficiency is higher, sturdy and durable, has enough erosion resistibility and larger firm
Degree, and non-deformability is strong, solid, smooth, good integrity.
The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
