Description
Technical field
The present invention relates to a kind of concrete road surface, especially a kind of prefabricated Steel Fibre Concrete Pavements.
Background technique
Currently, the energy conservation and environmental protection theory that China advocates has carried out building trade certain requirement, building trade is advocated
Environmental protection production.However, China's building engineering construction scene temporary road mostly uses disposable cast-in-place cement pavement at present,
This makes that a large amount of construction rubbish can be generated after the completion of construction, results in waste of resources.Prefabricated concrete road surface is being built
The value major embodiment for building engineering both ways, be on the one hand because prefabricated concrete can reuse brought by
On the other hand social value is then since cost is relatively low and may be reused to make for prefabricated concrete road surface
The building cost for obtaining enterprise, which is reduced, brings economic value to enterprise.But there are easy to wear, easily broken for current concrete prefabricated panel
Plate, the larger technical problems such as be not connected firmly between panel of self weight.
Summary of the invention
Goal of the invention: the invention discloses a kind of prefabricated Steel Fibre Concrete Pavements, solve in the prior art
The little frangibility of prefabricated panel intensity, technical problem easy to wear；It is biggish to solve prefabricated panel self weight in the prior art
Technical problem；Solution showed be not connected firmly between the panel having in technology by the technical issues of.
Technical solution: a kind of prefabricated Steel Fibre Concrete Pavements, including the steel fibre being laid on compacting road surface
The prefabricated panel of concreting is provided with cushion lime between the prefabricated panel and compacting road surface；The prefabricated panel packet
Multiple unit prefabricated panels are included, unit prefabricated panel edge is provided with multiple notches；The circular hole perforation being arranged in notch
The prefabricated panel；Connector is installed in the notch of two neighboring unit prefabricated panel；Bolt passes through on connector and notch
Circular hole fixed with cushion lime.
Specifically, notch is U type slot, adjacent unit prefabricated panel edge notch is corresponded, two adjacent slots
Mouth is spliced to form groove identical with connector shape, and the connector is installed in the groove.
Specifically, U type slot bottom offers blind round hole, the blind round hole with along the setting of notch symmetrical center line
Rectangular straight slot is connected；The connector two sides are provided with the cylindrical column mutually agreed with blind round hole, and two cylinders are vertical
Web is provided between column；The web width is identical as rectangular straight slot；The cylindrical column is installed in blind round hole；Institute
Web is stated to be installed in rectangular straight slot.Two circular holes on connector run through the cylindrical column of two sides.Install connection
After part and bolt, the casting concrete in groove.Groove inner concrete height is concordant with prefabricated panel upper level.
Specifically, reinforcing bar is arranged in prefabricated panel.Cushion lime is the 3:7 cushion lime of 300~400mm thickness.
The utility model has the advantages that its prefabricated panel of prefabricated Steel Fibre Concrete Pavements disclosed by the invention is by steel fibre coagulation
Soil pours, and can reduce the use of reinforcing bar to a certain extent even without using reinforcing bar, the case where reducing weight concrete
Under, the self weight of prefabricated panel, convenient transportation are reduced while increasing prefabricated panel rigidity and intensity.Novel connection type letter
Single firm, in-site installation is convenient, saves labour, accelerates speed of application.It the composite can be widely applied to different kinds of roads construction to build
In if.

Specific embodiment
As shown in Fig. 1~2, a kind of prefabricated Steel Fibre Concrete Pavements are more on compacting road surface including being laid on
The prefabricated panel 1 that a steel fiber reinforced concrete pours is provided with cushion lime 2 between prefabricated panel 1 and compacting road surface；Prefabricated panel
1 includes the unit prefabricated panel 11 of multiple rectangles, and 11 edge of unit prefabricated panel is provided with multiple notches 4；Setting in notch 4
Circular hole penetrate through prefabricated panel 1；Connector 3 is installed in the notch 4 of two neighboring unit prefabricated panel 11；Bolt 5 is worn
The circular hole crossed on connector 3 and notch 4 is fixed with cushion lime.Unit prefabricated panel 11 is generally square or rectangle knot
Structure.
Notch 4 is U type slot, and adjacent 11 edge notch 4 of unit prefabricated panel corresponds, two adjacent notches 4
It is spliced to form groove identical with 3 shape of connector, connector 3 is installed in the groove.11 four edges of unit prefabricated panel
On be respectively respectively set there are two notch 4；
As seen in figures 3-5, notch 4 is U type slot, and U type slot bottom offers blind round hole 41, blind round hole 41 with
Rectangular straight slot 42 along the setting of 4 symmetrical center line of notch is connected；3 two sides of connector are provided with the circle mutually agreed with blind round hole
Cylindricality column 31 is provided with web 32 between two cylindrical columns 31；32 width of web is identical as rectangular straight slot 42；The circle
Cylindricality column 31 is installed in blind round hole 41；Web 32 is installed in rectangular straight slot 42.
Two circular holes on connector 3 run through the cylindrical column 31 of two sides and connect with the circular hole on notch 4
It is logical.
In order to enable evenness of road surface, concrete has been poured in groove.Groove inner concrete height and 1 upper surface of prefabricated panel
Height is concordant.A small amount of reinforcing bar is set in prefabricated panel 1 or is not provided with reinforcing bar, because of steel fibre random distribution in concrete,
So that the examining tensile behavior of steel fiber reinforced concrete is preferable, the use of reinforcing bar can be reduced to a certain extent even without using reinforcing bar.
Cushion lime 2 is the 3:7 cushion lime of 300~400mm thickness.
For being compacted the corner on road surface, cushion lime is equipped with the prefabricated panel customized according to the actual situation or cast-in-place mixed
Solidifying soil layer.
