Description
Technical Field
The utility model relates to an anti seepage prevention structure that splits specifically is an anti working face structure that splits of garage under steel ingot milling type steel fiber concrete belongs to building technical field.
Background
As a building material with the largest use amount in modern civil engineering, the concrete has the advantages of easy forming, high compressive strength, good durability, low price and the like, is widely applied to various fields such as tunnels, bridges, roads, buildings, underground structures and the like, and is an irreplaceable material for civil engineering construction. However, the low tensile strength of concrete, a brittle building material, remains a difficult problem in its engineering applications.
At present, the steel bar mesh concrete construction process is mostly adopted for the leveling layer of the domestic underground garage, the traditional process has the problem that the steel bar mesh is attached to the ground, the anti-cracking effect which is required by concrete cannot be achieved, particularly, fine crack control cannot be well solved, then large-area cracks, long cracks and other destructive cracks are generated, the quality of subsequent surface layers (curing agent surface layers or epoxy floor paint surface layers) is directly influenced, and finally the service life of the floor is greatly reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a steel ingot mills anti working face structure that splits of shaped steel fibre concrete garage under land to solve prior art's above-mentioned problem.
The purpose of the utility model is realized by the following technical scheme.
A steel ingot milling type steel fiber concrete underground garage anti-cracking working surface structure comprises a moisture-proof layer laid on a foundation, wherein a cushion layer is laid on the moisture-proof layer; an isolation layer is laid on the cushion layer; the isolation layer is a concrete leveling layer with the thickness of 6-10 cm, the leveling layer is covered with a carborundum wear-resistant layer, and the wear-resistant layer is covered with a first surface layer made of a cement-based self-leveling material or a resin floor coating material; and steel ingot milling type steel fibers are uniformly distributed in the concrete of the leveling layer.
The steel fiber is of a sheet structure, one surface of the steel fiber is smooth, and the other surface of the steel fiber is rough; the smooth surface of the steel fiber is bent towards the rough surface to form a cambered surface along the long edge; two ends of the steel fiber are pressed into step-shaped anchor tails; the steel fiber body is twisted clockwise around the long side direction. The structure can ensure that the steel fibers are uniformly distributed to all places of the concrete when being mixed with the concrete.
The length of the steel fiber is 2.5-3.5 cm; the width is 2-5 cm.
And a second surface layer made of a cement-based wear-resistant material or a concrete liquid hardening agent is laid on the upper sides of the cushion layer and the leveling layer.
The structural layer of the utility model is the cushion layer.
The utility model has the advantages that:
1. the steel ingot is used for milling the steel fibers to replace the original reinforcing mesh, fine cracks of concrete are well controlled, a large number of cracks are reduced, and the service life of the whole terrace is guaranteed.
2. The steel ingot milling type steel fiber concrete is adopted, the conventional leveling layer with the thickness not less than 30 cm can be thinned to 6-10 cm, and materials are saved.
3. Because the steel fiber is milled for the steel ingot, the edge of the steel fiber is in a sawtooth shape, and the bonding force with concrete is increased.

Detailed Description
The structural features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
The steel ingot milling type steel fiber concrete underground garage anti-cracking working surface structure shown in figure 1 comprises a moisture-proof layer 1 laid on a foundation, and a cushion layer 2 laid on the moisture-proof layer 1; an isolation layer 3 is laid on the cushion layer 2; the isolation layer 3 is provided with a concrete leveling layer 4 with the thickness of 6-10 cm, the leveling layer 4 is covered with a carborundum wear-resistant layer 6, and the wear-resistant layer 6 is covered with a first surface layer 7 made of a cement-based self-leveling material or a resin floor coating material; and steel ingot milling type steel fibers 5 are uniformly distributed in the concrete of the leveling layer 4.
The steel fiber 5 is of a sheet structure, one surface of the steel fiber is smooth, and the other surface of the steel fiber is rough; the smooth surface of the steel fiber is bent towards the rough surface to form a cambered surface along the long edge; two ends of the steel fiber are pressed into a step-shaped anchor tail 8; the steel fiber body is twisted clockwise around the long side direction. The structure can ensure that the steel fibers are uniformly distributed to all places of the concrete when being mixed with the concrete.
The length of the steel fiber is 2.5-3.5 cm; the width is 2-5 cm.
And a second surface layer made of a cement-based wear-resistant material or a concrete liquid hardening agent is laid on the upper sides of the cushion layer and the leveling layer.
When the concrete mixer is used, a proper amount of the steel fibers 8 are added into concrete in the process of stirring the concrete, and the steel fibers are gradually and uniformly dispersed into the concrete under the action of external force of stirring and fluid of the concrete due to the self-twisted structure of the steel fibers 5. After the concrete is poured and molded, the steel fiber pulls a certain section of concrete block through the structure of the anchor tail, so that a larger crack is prevented from being opened; under the combined action of a plurality of steel fibers, the whole concrete block is difficult to crack. In the utility model, the steel fiber added in each cube is 18-25kg, so that the control of the fine cracks of the leveling layer can be realized, and the service life is prolonged by 2-3 years.
