Description

TECHNICAL FIELD

[0001] The utility model relates to a factory building concrete ground surface anti-cracking structure technical field, concretely is a factory building concrete ground surface anti-cracking structure. BACKGROUND

[0002] Since the invention of Portland cement, cement has been one of the most important building materials. Because it belongs to hydraulic inorganic cementitious material and has high compressive strength and elastic modulus, it can be used to prepare various concrete, reinforced concrete, prestressed reinforced concrete components and structures, and can also be used to prepare various mortars and as grouting material, so it is widely used in aboveground, underwater and underground engineering. Among them, cement mortar is most widely used in ground due to its simple construction method and low engineering cost, and is widely used in industrial and civil buildings.

[0003] Generally, the crack control of concrete mainly reduces the internal tensile stress of concrete or improves the tensile capacity of concrete itself. At present, most of the methods for crack control are to reduce the internal tensile stress of concrete, such as using low elastic modulus buffer layer to reduce the constraint degree of bottom concrete on upper concrete, using cooling water or hydration heat inhibitor to reduce the internal temperature rise peak value of mass concrete, using shrinkage compensation concrete and using shrinkage reducing water reducing agent to reduce the shrinkage of concrete, etc.

[0004] In actual use, by reducing the internal tensile stress of concrete, only the shrinkage cracking of concrete can be reduced, but after the concrete pavement is formed, vehicles will often be rolled on the pavement, and the pavement will still have a high probability of cracking after being subjected to pressure for a long time, which will seriously affect the appearance and normal use of the pavement, therefore, it is necessary to provide a new kind of factory building concrete ground surface anti-cracking structure to solve the above technical problems. UTILITY MODEL CONTENTS

[0005] The purpose of this utility model is to provide a crack-resistant structure for concrete floors in factory buildings, which has the advantages of tensile strength, crack prevention, waterproofing, fireproofing, and improved stability, thus solving the problems in the background art. To achieve the above objective, this utility model provides the following technical solution: a crack-resistant structure for concrete floors in factory buildings, comprising: a foundation, on the top of which a concrete layer is fixedly connected; and a protective component, comprising reinforcing steel columns, which are uniformly fixedly connected inside the concrete layer. During the pouring process, the reinforcing steel columns are evenly placed inside the concrete layer, and then interwoven with wire mesh to form a whole, which can improve the crack resistance and impact resistance of the concrete layer. Secondly, the upper and lower rubber pads can buffer the pressure on the road surface when heavy objects pass over the road surface, preventing cracks in the road surface caused by external forces, thus greatly improving the crack resistance of the road surface. The fireproof layer, heat insulation layer, and waterproof layer provide good protection for the concrete floor, reducing the impact of external factors on the concrete layer and preventing cracking of the concrete floor to a certain extent.

[0006] Preferably, the protective component further includes a wire mesh, which is uniformly and fixedly connected to the outside of the reinforcing bar column. The upper and lower ends of the reinforcing bar column are respectively provided with an upper rubber pad and a lower rubber pad. The wire mesh is interwoven to make the reinforcing bar column interwoven into a whole, which can improve the crack resistance and impact resistance of the concrete layer. Secondly, the upper and lower rubber pads can buffer the pressure on the road surface when heavy objects pass over the road surface, preventing the concrete layer from cracking due to external forces, and greatly improving the crack resistance of the road surface.

[0007] Preferably, the top of the upper rubber pad is provided with a thermal insulation layer. The thermal insulation layer is made of polystyrene foam. Polystyrene foam board is a white object formed by heating expandable polystyrene beads containing volatile liquid foaming agents in a mold after pre-expansion. It has the characteristics of micro-closed-cell structure, which reduces the pressure caused by structural deformation due to temperature changes and reduces the erosion of the structure by harmful substances and ultraviolet rays in the air. At the same time, it can effectively eliminate "thermal bridge". In the past, when internal insulation was used, "thermal bridge" was difficult to avoid. However, external wall insulation effectively prevents the generation of thermal bridge, avoids condensation, and improves the moisture and temperature of the concrete floor. Generally, internal insulation requires an air barrier layer, while the thermal permeability of external insulation materials is much stronger than that of the main structure. Condensation generally does not occur inside the concrete layer.

[0008] Preferably, a waterproof layer is provided on top of the insulation layer. The waterproof layer is a polyurethane waterproof coating, which has strong elasticity, weather resistance and impermeability, is suitable for surfaces with complex shapes, and can effectively fill cracks.

[0009] Preferably, the top of the waterproof layer is fixedly connected with a fiber layer, the material of the fiber layer is basalt fiber mesh, which has excellent acid resistance, alkali resistance, salt resistance and other chemical corrosion resistance.

[0010] Preferably, the top of the fiber layer is fixedly connected with a fireproof layer, the material of the fireproof layer is a fireproof blocking material with an organic synthetic resin as an adhesive, the blocking material does not solidify for a long time and has good plasticity, the fireproof blocking material is non-toxic, odorless, and has good water resistance, oil resistance and other properties.

[0011] Preferably, the top of the fireproof layer is provided with a top surface, and expansion joints are uniformly arranged on the top of the top surface, so that the concrete layer will not produce irregular cracks due to shrinkage during hardening and when the temperature decreases, so as to avoid affecting the flatness of the road surface.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] Firstly, in the pouring process, the reinforcing columns are uniformly placed in the concrete layer, and then the reinforcing columns are interwoven into a whole through the mutual interweaving of the steel wire meshes, so that the crack resistance and impact resistance of the concrete layer are improved.

[0014] Secondly, the upper rubber pad and the lower rubber pad are arranged, so that when the heavy object passes through the road surface, the pressure on the road surface can be buffered, the cracks on the road surface caused by external force are avoided, and the crack resistance of the road surface is greatly improved.

Secondly, the upper rubber pad 8 and lower rubber pad 9 can buffer the pressure on the road surface when heavy objects pass over the road surface, preventing cracks in the road surface caused by external forces, thus greatly improving the crack resistance of the road surface. The fireproof layer 4, the heat insulation layer 7, and the waterproof layer 6 provide good protection for the concrete floor, reducing the impact of external factors on the concrete layer 2 and preventing cracking of the concrete floor to a certain extent.

[0023] An insulation layer 7 is installed on top of the upper rubber pad 8. The insulation layer 7 is made of polystyrene foam. Polystyrene foam board is a white object formed by heating expandable polystyrene beads containing volatile liquid foaming agents in a mold after pre-expansion. It has the characteristics of micro-closed cell structure, which reduces the pressure caused by structural deformation due to temperature changes and reduces the erosion of the structure by harmful substances and ultraviolet rays in the air. At the same time, it can effectively eliminate "thermal bridge". In the past, when internal insulation was used, "thermal bridge" was difficult to avoid. However, external wall insulation effectively prevents the generation of thermal bridge, avoids condensation, and improves the moisture and temperature of the concrete floor. Generally, internal insulation requires an air barrier layer, while the heat permeability of the external insulation material is much stronger than that of the main structure. Condensation generally does not occur inside the concrete layer 2.
