Abstract

The utility model belongs to the field of building material, and discloses a grass-planting brick capable of being embedded with steel bar, especially a grass-planting rainwater-permeable brick for environment-friendly stopping pad, which comprises columnar face brick disposed on base. The base comprises a #-shaped support and #-shaped grooves arranged on the support for embedding steel bar; total height of the base is 40-60 mm; total height of the face brick and base is 100-140 mm; and the face brick is round cylinder or rounded square column with certain de-molding taper. The utility model has advantages of simple structure, easy construction, high grass planting rate, and growth of continuous lawn. The steel bar can improve integral strength and damage resistance of the brick, and guarantee rainwater permeation to conserve groundwater, maintain ecological balance, and utilize rainwater.

Description

Can bury the grass planting brick of reinforcing bar underground

Technical field:

The utility model relates to a kind of grass planting brick of burying reinforcing bar underground.It belongs to building materials field, particularly a kind ofly is applicable to stopping pad grass planting brick green grass, that can carry out the environment-friendly type stopping pad that rainwater bleeds back.

Background technology:

At present the domestic and international stopping pad of producing is divided into two classes from the appearance with the grass planting brick: a class is to be with the grass planting brick of collet, and its operating principle is similar to a plurality of flowerpots and connects together, and during work soil is covered on the collet grass planting again; Another kind of is the grass planting brick of no collet, and its outer appearnce forms like the through hole of opening one or several up/down perforations on thicker concrete road pavement brick.The common similar container of containing soil, both the grass planting hole of forming in these holes and ground.Above-mentioned grass planting brick exists following shortcoming: one when the grass planting brick of band collet is sat the slurry making, almost with all penetrating passage sealings, is unfavorable for lawn growth, and makes rainwater be difficult to infiltrate the earth.The second, because the existence of collet, for the grass planting brick of equal height, the overburden layer thickness of the grass planting brick of band collet is significantly less than the grass planting brick of not being with collet.The 3rd, its hole ratio of grass planting brick with collet has not determined its grass planting rate, but the ratio of the area of grass planting part and area that can not the grass planting part on the grass planting brick (be called for short careless brick than) therefore is restricted.Its reason is: because the through-hole structure of grass planting brick, when its hole ratio is big more, itself and basic unit's contact area of ground are just more little, and be just high more to the requirement for bearing capacity on basic unit ground, and also high more to the requirement of the strength of materials of grass planting brick own, institute should not do careless brick ratio too much.The hole ratio of common grass planting brick generally is not more than 1 to 1, and the grass planting rate is not more than 50%, otherwise too high to the requirement for bearing capacity of basic unit, and brick is also broken easily.The 4th, the through-hole structure with the grass planting brick of collet does not make grass independent existence in each hole, and promptly their root system can not be scurried in other hole.So when the grass in certain hole does not survive, can not have grass roots in other hole to scurry and make this hole grow grass again, must reseed.The 5th, no matter be the grass planting brick of band collet or not with the grass planting brick of collet, loosening in order to prevent the grass planting brick, generally all need to sit slurry making grass planting brick with cement mortar.So even stopping pad basic unit is permeable, because the existence of cement mortar tack coat, the stopping pad that finally is paved into can not play the effect that rainwater is bled back.And hard ground comprises the stopping pad rainwater to bleed back is self-restraint underground water, keeps ecological balance and the important measures of rainwater utilization.

Summary of the invention:

The purpose of this utility model be to provide a kind of cheap, easy making, not cracky, the grass planting rate is high and can make the grass planting brick of buried underground the reinforcing bar that the lawn grows in flakes.

The purpose of this utility model is achieved in that

A kind of grass planting brick of burying reinforcing bar underground, it comprises face brick piece and base, it is characterized in that described face brick piece is cylindricality, places on the described base; On described base, offer the groined type groove that to bury reinforcing bar underground.

The overall height of described base is 50～80mm; The height overall of described face brick piece and base is 100～160mm.

The cross dimensions of the notch of described groined type groove is greater than the sectional dimension of groove.

Described face brick piece is the cylindrical or chamfering square column type with certain demoulding tapering.

The utility model is simple in structure, easy making, grass planting rate height, and grown in flakes in the lawn.Because action of steel bars is arranged, can be so that the ground of adopting the utility model to lay forms an integral body, it is local loosening to be not easy to cause the ground of being laid to take place, and can guarantee that the stopping pad rainwater bleeds back, and can realize conserving underground water, keep ecological balance and the utilization of rainwater.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model

The specific embodiment:

Be embodiment of the present utility model with accompanying drawing 1 below, the utility model be further detailed:

The utility model is made up of face brick piece 1 and base 2 two parts that can bury reinforcing bar underground.Described face brick piece 1 is cylindricality, places on the described base 2; On described base 2, be provided for burying underground the well word groove 3 of reinforcing bar 4.Face brick piece and base all adopt concrete for making.Base is produced in factory, can adopt extrusion modling or adopt plastic cement mould vibrating forming.The face brick piece can be produced in factory, also can adopt the moulding of simple face brick block forming die poured in place concrete at the construction field (site).When by the polylith base on the ground the time, can be combined into co-ordination apart from grid uniformly.In the groove 3 of base, can bury reinforcing bar 4 underground.The height of base is 70mm, and the height overall of face brick piece and base is 140mm.Obviously, all the making areas except that face brick piece sectional area are the grass planting area.

Adopt the job practices of the utility model laying stopping pad as follows: above-mentioned grass planting brick is laid in the basic unit of stopping pad.Before the laying, stopping pad basic unit should lay rubble and stone flour slag and compacting and offset.During laying earlier with base by latticed put neat, smooth, in groove 3, put reinforcing bar 4, fill up above-mentioned groove with good fluidity concrete or mortar 5 again, the face brick piece is bonded on the grid node or adopts face brick block forming die poured in place concrete to obtain above-mentioned face brick piece then with mortar.Maintenance 7～28 days makes whole ground become a rigid unitary.Because there is mesh in above-mentioned grid, so the ground that has certain area can not covered by base or mortar.This part pervious surface is easy to keep its water permeability, can make real rainwater and bleed back stopping pad.At last soil is layered in the face brick piece zone all around and the kind grass.After grass survived, grass roots can " be scurried root " along the soil around the face brick piece, helps the lawn and grows in flakes.The cross dimensions of the notch 6 of described groined type groove 3 makes the cast-in-situ concrete of the junction between brick body and brick body or the sectional dimension of mortar 5 increase greater than the sectional dimension of groove 3.
