Description

Blind road brick

Technical Field

The utility model relates to the field of pavement brick materials, in particular to a blind road brick which is widely used for sidewalks and pedestrian streets in cities; squares and parking lots; seashore avenues of lakes (rivers) shore, harbors, etc.; a parking lot of a highway gas station and a transition zone from a highway to the parking lot; roadways and parking lots of basic facilities such as ports, wharfs and the like.

Background

A permeable concrete pavement brick (blind road brick) is a concrete pavement brick which can bear large load and can enable water to permeate below and even underground through the surface of concrete.

Most of the prior pavement brick (blind road brick) products have the following defects: firstly, the surface layer is easy to fall off, cracks and stains on the surface layer are serious; the brick surface has serious efflorescence phenomenon; the strength of the brick is unqualified, and the brick is easy to break integrally; water permeability and water retention are not ideal; the performance such as freeze thawing resistance, compression resistance, fracture resistance and the like is unqualified. Secondly, the structure is unreasonable, the overall beautiful effect is poor, the whole structure is not coordinated with the surrounding landscape environment, especially after the damaged road surface appears; the construction at the edge is random and the connection is unreasonable.

Disclosure of Invention

The utility model aims to provide a blind road brick of simple structure reasonable, easy, sturdy and durable, the convenient construction of making, beautifying the environment.

The utility model aims at realizing like this, this blind way brick includes a blind way brick main part, blind way brick main part be the cuboid structure, blind way brick main part corresponding around two sides with control two side parallel symmetry, it is protruding to have two vertical arc surfaces around two sides, it is protruding to have a vertical arc surface about on two sides, the upper surface of blind way brick main part still has two bar direction approaches.

The utility model has the advantages of it is following and positive effect:

1. simple and reasonable structure, beautiful appearance, durability, rich colors and high compressive strength (30-60 Mpa). Has the unique functions of rigid surface and flexible connection, has good deformation resistance, and is particularly suitable for flexible foundations with large deformation.

2. The anti-skidding and water permeability is high, the surface and the inside of the product have rich pores, the anti-skidding effect is good in rainy and snowy days, rainwater is effectively permeated and filtered, the ecological system of pavement soil is improved, and the hot and alarming effect of the pavement is reduced.

3. Reducing non-point source pollution: effectively absorb harmful substances (atmospheric particulates) in the air, reduce traffic noise and reduce urban water quality and soil pollution.

4. Natural materials: the broken stone, aggregate, water, dye and the like are mixed and hydraulically vibrated to be formed, and the strength is averagely maintained to be more than 30 MPa.

5. The building block has excellent water retention and permeability, is rich in underground water, can relieve the heat island effect caused by the increase of greenhouse gases in cities, and brings fresh and cool smell to cities. In continuous rainy days and rainstorms in summer, the water quantity can be controlled, and flood control and flood discharge can be effectively realized.

6. The economic performance is good, reduces carbon emission, prevents flood, saves the cost of purifying water source.

Detailed Description

Shown in figures 1, 2, 3, 4, 5: the blind sidewalk brick comprises a blind sidewalk brick main body 1, wherein the blind sidewalk brick main body 1 is of a cuboid structure, the blind sidewalk brick main body 1 is symmetrical in parallel with a front side surface 1-1 and a rear side surface 1-2 and a left side surface 1-3 and a right side surface 1-4, the front side surface 1-1 and the rear side surface 1-2 are provided with two vertical arc surface bulges 1-5, the left side surface 1-3 and the right side surface 1-4 are provided with one vertical arc surface bulge 1-5, and the upper surface of the blind sidewalk brick main body 1 is also provided with two strip-shaped direction guide bulges 1-6.

The vertical arc surface bulges 1-5 have the following functions: prevent during expend with heat and contract with cold that the brick of mating formation from bulging, play a flexible link, prevent the brick face and face contact to and rainwater infiltration's effect prevents surface gathered water.

The height G of the vertical arc surface bulges 1-5 is 53.5mm, the length M of the blind sidewalk brick main body 1 is 198mm, the width N is 98mm, the thickness H is 80mm, and the distance G between the two vertical arc surface bulges 1-5 arranged on the front side surface 1-1 and the rear side surface 1-2 is 100 mm.

In FIG. 2, a is 16mm and b is 49 mm.

The utility model discloses blind way brick can adopt arbitrary construction standard requirement to be under construction when the construction.
