Abstract

The utility model discloses a granite concrete paving brick, which comprises a face layer and a bottom layer. The face layer is made of mixture of cement, hilly sand and granite, the bottom layer is made of mixture of cement, hilly sand and broken stones, and the face layer and the bottom layer are laminated into a whole; and the profile of the granite concrete paving brick consists of a cross and reinforcing inclined block sides connected with every two adjacent right-angle sides of the cross. The granite concrete paving brick has the advantages of good wear resistance, high strength, uniform stress, simple and convenient construction, good drainage performance, low fabrication cost and long service life. Through the comparison of tests conducted under the same brick thickness and the same service environment conditions, the service life of the granite concrete paving brick is 2-3 times of the service life of the traditional concrete brick. The granite concrete paving brick can be widely used in large-scale load-bearing roads, wharfs, squares, sidewalks, retaining slopes, lawn roads, etc.

Description

A kind of granolith pavior brick

Technical field

The utility model relates to a kind of granolith pavior brick, belongs to the pavior brick building material technical field.

Background technology

At present, concrete road pavement brick of the prior art is with cement and to gather materials be main raw material(s), makes through processing, pressurization or other moulding process and is shaped as triangle, square, orthohexagonal concrete road pavement brick.Concrete road pavement brick is mainly used in the piece, plate of rigid pavements such as laying urban road, sidewalk, city square and ground surface works etc.These concrete road pavement bricks of the prior art exist following problem: abrasion resistance is bad, and its surface spoilage under the wearing and tearing of the vehicles such as automobile is very high; Intensity is not high, can occur the situation of corner fragmentation under the weight of the vehicles such as automobile; Drainage performance is not good, easily ponding.Because concrete road pavement brick of the prior art exists the problems referred to above, so its result of use still is not ideal enough.

Summary of the invention

The purpose of this utility model is, provide that a kind of abrasion resistance is better, intensity is higher, stressed evenly, easy construction is quick, drainage performance is better, grow application life granolith pavior brick, to overcome the deficiencies in the prior art.

The utility model is achieved in that a kind of granolith pavior brick of the present utility model, be being that raw material is mixed into the surface layer of one and is that the bottom that raw material is mixed into one is formed by cement, mountain sand, rubble by cement, mountain sand and granite, surface layer and bottom are compressed to one.

The profile of above-mentioned granolith pavior brick is cross and the lantern shape that reinforcement skewback limit is combined into, and promptly is connected with on criss-cross per two adjacent right-angle sides and strengthens the skewback limit.

The thickness of above-mentioned surface layer is 3mm～8mm, and the thickness of bottom is 40mm～60mm.

Because having adopted technique scheme, the utility model to adopt granite on the surface is the wearing layer of material, surface aesthetic no-reflection and wear-resisting anti-skidding; Its profile is " lantern " shape, easy construction, and rainwater is difficult for residual; And in use, stressed even, the corner is difficult for crushed.Therefore, the utility model compared with prior art, the utility model not only has the advantage that abrasion resistance is good, intensity is high, but also have stressed evenly, easy construction is quick, drainage performance good, cheap, advantage that application life is long, through under the identical environment for use condition and the comparison of the test under the thickness situation of identical brick, to be higher than 2～3 times of application lifes of conventional concrete brick application life of the present utility model.The utility model can be widely used in large-size bearing road and harbour, square, sidewalk, retaining slight slope and lawn road etc.Through evidence, use the utility model to reduce maintenance work significantly, use manpower and material resources sparingly.

The specific embodiment

Below, in conjunction with the accompanying drawings and embodiments the utility model is further described.

Embodiment of the present utility model: when making granolith pavior brick of the present utility model, this granolith pavior brick is made into by cement, mountain sand and granite are that raw material is mixed into the surface layer 1 of one and by cement, mountain sand, rubble is bottom 2 compositions (as shown in Figure 2) that raw material is mixed into one, and surface layer 1 and bottom 2 mode by compression moulding is compressed to one, it is cross and the lantern shape (as shown in Figure 1) that reinforcement skewback limit 3 is combined into that its shape is pressed into profile, promptly is connected with on criss-cross per two adjacent right-angle sides and strengthens skewback limit 3; During making, the thickness B 1 of surface layer 1 can be controlled at the scope of 3mm～8mm according to the needs that use, and the thickness B 2 of bottom 2 is controlled at the scope of 40mm～60mm.

During making, preferably make: promptly adopt cement, mountain sand and rubble as the bottom raw material by the preparation method of following granolith pavior brick, after mountain sand and rubble pulverizing, get 10～30 parts in 90～110 parts of cement, 450～550 parts in mountain sand, 450～550 parts of rubbles and water by weight, after each raw material mixed the bottom mixed material, it is standby in the bottom mould that the bottom mixed material is packed into; Adopt cement, mountain sand and granite are as the surface layer raw material, with mountain sand, after granite and rubble are pulverized, get 90～110 parts of cement by weight, 280～320 parts in mountain sand, 10～30 parts in 20～70 parts in granite and water, after each raw material mixed the surface layer mixed material, the surface layer mould is placed on the bottom mould that the bottom mixed material is housed then, again the surface layer mixed material is filled up in the surface layer mould, this double stack mold that has filled up surface layer mixed material and bottom mixed material put in 80 tons～110 tons the forcing press and vibrate extrusion forming, can make the granolith pavior brick like this.

In above-mentioned raw material, cement adopts existing intensity to be equal to or greater than 42.5 Portland cement; The grain diameter of its mountain sand is controlled at the scope that is less than or equal to 1.25mm; Rubble adopts the rubble of 5～10mm grating.

When laying granolith pavior brick of the present utility model, can adopt following job practices to carry out:

1, former soil layer is handled: according to designing requirement, and the roadbed excavation, the cleaning earthwork, and reach design elevation; Check longitudinal gradient, horizontal wall inscription and sideline, whether adhere to specification; The finishing roadbed, the levelling grinding compacting, coefficient of consolidation reaches more than 95%, and the pipeline of attentively burying underground down.

2, base layer construction: lay the thick graded sand and stone of 150～180mm, (maximum particle diameter must not surpass 60mm, and minimum grain size must not surpass 0.5mm) and levelling grinding compacting, compactness reaches more than 95%.

3, leveling layer is laid: the leveling layer medium sand, and 30mm is thick, and medium sand requires to have certain grating, i.e. the graded sand levelling of particle diameter 0.3～5mm.

4, lay granolith pavior brick of the present utility model: according to laying requirement, determine reference line, laying should begin once to carry out by design scheme from the arm of angle, should guarantee in the laying that pavior brick is in conjunction with closely, with the compacting of glue hammer.Pavior brick can cut into auxiliary block shape with steel disc, is used for irregular paved surfaces such as corner.

5, road surface jolt ramming: after laying was finished, the surface was vibrated 2～3 times to the centre by the edge repeatedly with the plate vibration machine.

6, cleaning road surface.
