Abstract
The utility model relates to the technical field of roads, in particular to a double-layer combined type road surface shaped brick and connecting bolts. The utility model is characterized by being provided with a brick body which is provided with four holes; the four holes are internally provided with the connecting bolts; and the four holes arranged on the brick body are stepped holes the diameters of which are larger than or equal to those of the upper surface and the lower surface of the brick body and the diameters of the middle parts of which are smaller. When the double-layer combined type road surface shaped brick and the connecting bolts are used for paving the road surface, the plurality of shaped bricks are paved into double layers in a staggered manner, the connecting bolts are penetrated into the four stepped holes so as to lead the shaped brick at the upper layer and the shaped brick at the lower layer to be fixedly connected into the road surface. The utility model has the advantages of reasonable structure, surface-interchangeable use, longer service life and low cost, and the like.
Description
Technical field
The utility model relates to road technology field, is a kind of double-layer combined road surface with shaped brick and coupling bar.
Background technology
Existing road surface is to adopt the square brick individual layer to lay to constitute, and its weak point is that the upper layer of square brick is prone to defective or damage, make pavement roughness and influence presentation quality, often the local defect because of the square brick upper layer causes square brick to be scrapped, and application life is short, the cost height.
Summary of the invention
The purpose of this utility model is, overcomes the prior art deficiency, provides a kind of rational in infrastructure, interchangeable use, and the double-layer combined road surface that comparative lifetime is long, cost is low is with shaped brick and coupling bar.
Realize that the technical scheme that the purpose of this utility model adopted is, a kind of double-layer combined road surface is with shaped brick and coupling bar, and it is characterized in that: it has the brick body, and four holes are set on the brick body, in four holes coupling bar is housed.
Four holes that are provided with on the described brick body are big and equal, that mid diameter the is little stepped hole of relative brick body above and below diameter.
When using double-layer combined road surface of the present utility model with shaped brick and coupling bar road surface pavement, with the staggered bilayer that is laid to of some shaped bricks, coupling bar is threaded onto upper and lower stratotype brick is connected constitute the road surface, have rational in infrastructure, interchangeable use, comparative lifetime is long, low cost and other advantages.
Description of drawings
Fig. 1 is double-layer combined road surface with shaped brick and coupling bar structural representation (the A-A sectional view of Fig. 2).
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
Utilize drawings and Examples that the utility model is further described below.
With reference to Fig. 1 and 2, double-layer combined road surface of the present utility model has brick body 1 with shaped brick and coupling bar, and four holes 2 are set on brick body 1, in four holes 2 coupling bar 3 is housed.Four holes 2 that are provided with on the described brick body 1 are big and equal, that mid diameter the is little stepped hole of relative brick body 1 above and below diameter.
When using double-layer combined road surface of the present utility model, be laid to bilayer with some shaped bricks are staggered, coupling bar 3 is threaded onto in four stepped holes 2 of shaped brick brick body 1 upper and lower stratotype brick is connected to constitute the road surface with shaped brick and coupling bar road surface pavement.When local defect appears in certain piece shaped brick upper layer, will descend surface layer to be inverted into upper layer and get final product.Owing to adopt the double deck type brick structure, also two-layer shaped brick transposing can be used.
Double-layer combined road surface of the present utility model adopts current material and technology to make with shaped brick, with constructional materialss commonly used such as cement, uses Mold Making; For increasing the intensity of shaped brick, can when making, reinforcing mat or reinforcing rib be set in mould.Coupling bar 3 also adopts constructional materialss commonly used such as cement, uses Mold Making; Also can in coupling bar 3, reinforcing rib be set.The utility model is suitable for the laying of urban road surfaces, grassland and desert pavement of road.Also can be used for building uses such as body of wall.
Claims (2)
