Abstract
Description
Technical Field
[0001] The present application relates to the technical field of concrete floors, and in particular to an anti-cracking structure of concrete floors. Background Art
[0002] Since the invention of silicate cement, cement has been one of the most important materials for construction projects. As it is a hydraulic inorganic cementitious material with high compressive strength and elastic modulus, it can be used to prepare concrete, reinforced concrete, prestressed reinforced concrete components and structures of various types and strength levels, and can also be used to prepare various mortars and used as grouting materials, etc., so it is widely used in above-ground, underwater and underground projects.
[0003] Generally speaking, crack control of concrete mainly starts from two aspects: reducing the tensile stress inside concrete or improving the tensile capacity of concrete itself. At present, most of the methods used to control cracks are to reduce the tensile stress inside concrete, such as using a low elastic modulus buffer layer to reduce the constraint of the bottom concrete on the upper concrete, using cooling water or hydration heat inhibitor to reduce the peak temperature rise inside large-volume concrete, using shrinkage-compensating concrete and using shrinkage-reducing water-reducing agents to reduce the shrinkage of concrete, etc.
[0004] In actual use, by reducing the tensile stress inside the concrete, only the shrinkage cracking of the concrete can be reduced. However, after the concrete pavement is formed, since vehicles will often roll over the road surface, there is still a high probability of cracking when the road surface is under pressure for a long time, which will seriously affect the appearance of the road surface and the normal use of the ground. For this reason, the present application provides an anti-cracking structure for concrete floors. Utility Model Content
[0005] The purpose of the present application is to solve the problem that the road surface is still likely to crack after being under pressure for a long time. The present application provides an anti-cracking structure for concrete floors.
[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:
[0007] A concrete floor anti-cracking structure comprises a foundation surface, a concrete layer is arranged on the top of the foundation surface, a top surface is arranged on the top of the concrete layer, a shrinkage joint is opened on the top of the concrete layer, steel bars are installed inside the concrete layer, stainless steel wires are installed inside the concrete layer, and a buffer block is installed inside the concrete layer.
[0008] By adopting the above technical solution, the steel bars and stainless steel wires are evenly fixed inside the concrete layer, thereby improving the tensile capacity of the concrete layer and avoiding cracks. At the same time, when the concrete layer is solidifying, the shrinkage joints can ensure that the concrete layer will not produce irregular cracks due to shrinkage during the hardening process and when the temperature drops, so as not to affect the flatness of the road surface.
[0009] Furthermore, a fiber layer is provided at the bottom of the top surface, and the fiber layer is made of basalt fiber mesh.
[0010] By adopting the above technical solution, the basalt fiber mesh has the advantages of high tensile strength, large ultimate elongation and good alkali resistance, which can improve the tensile strength, bending resistance, elongation and toughness of concrete and thus improve crack resistance.
[0011] Furthermore, a heat-insulating layer is arranged at the bottom of the fiber layer, and the material of the heat-insulating layer is a polystyrene foam board.
[0012] By adopting the above technical solution and setting up a thermal insulation layer, the "thermal bridge" phenomenon inside the concrete layer can be effectively eliminated, so that condensation will not occur inside, the stability of the concrete layer will be improved, and cracking will be avoided.
[0013] Furthermore, a plurality of steel bars are evenly and symmetrically fixedly connected inside the concrete layer, the stainless steel wires are fixedly connected to the bottom of the steel bars, and the stainless steel wires are crisscrossed in a grid shape.
[0014] By adopting the above technical solution, the stainless steel wires are laid in a criss-cross pattern at the bottom of the steel bars, and the interior of the concrete layer is evenly divided into a grid, thereby improving the crack resistance and impact resistance of the concrete layer.
[0015] Furthermore, two supporting plates are fixedly connected between the upper and lower parts of the stainless steel wire.
[0016] By adopting the above technical solution, the two ends of the support plate are connected with stainless steel wires, which greatly improves the impact resistance of the concrete layer and makes it more resistant to external impact.
[0017] Furthermore, the two support plates are cross-fixedly connected to each other, and the two support plates cross-connect between the stainless steel wires to form a triangle.
[0018] By adopting the above technical solution, the two ends of the support plate are connected with stainless steel wires to form a triangular cross support. According to the stability of the triangle, the impact resistance of the concrete layer is greatly improved, and it is more resistant to external impact.
[0019] Furthermore, a buffer block is symmetrically fixedly connected to the bottom of the stainless steel wire, and the bottom of the buffer block is tightly fitted to the foundation surface.
[0020] By adopting the above technical solution, when a heavy object passes on the road surface, the concrete layer will exert pressure on the buffer block, distributing the pressure to the foundation surface, which can effectively buffer the pressure on the road surface and prevent the concrete layer from being affected by external forces and causing cracks in the road surface, thereby greatly improving the road surface's resistance to cracking.
[0021] Furthermore, the buffer block is in an I-shape, and the length of the upper end of the buffer block is smaller than the length of the lower end.
[0022] By adopting the above technical solution, since the length of the upper end is smaller than the length of the lower end, the pressure can be distributed to the foundation surface, which can effectively buffer the pressure on the road surface.
[0023] In summary, the present application includes at least one of the following beneficial effects:
[0024] 1. The present application is provided with steel bars, stainless steel wires and support plates. The stainless steel wires are criss-crossedly laid at the bottom of the steel bars to evenly divide the interior of the concrete layer into a grid shape to improve the crack resistance and impact resistance of the concrete layer. Secondly, the two ends of the support plate are connected to the stainless steel wires to form a triangular cross support. Due to the stability of the triangle, the impact resistance of the concrete layer is greatly improved, and it is more resistant to external impacts, thereby avoiding cracking of the concrete layer after being impacted.
[0025] 2. The present application is provided with a buffer block. When a heavy object passes through the road surface, the concrete layer will be squeezed toward the buffer block under pressure. The buffer block distributes the pressure to both sides of the foundation surface, effectively buffering the pressure on the road surface and preventing cracks in the concrete layer due to external forces, thereby greatly improving the road surface's resistance to cracking.

[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] The embodiment of the present application discloses an anti-cracking structure for a concrete floor.
[0033] Reference Figure 1-Figure 3 A concrete floor anti-cracking structure includes a foundation surface 1, a concrete layer 2 is laid on the top of the foundation surface 1, a top surface 3 is laid on the top of the concrete layer 2, a plurality of evenly arranged shrinkage joints 6 are opened on the top of the concrete layer 2, a plurality of evenly distributed steel bars 7 are installed inside the concrete layer 2, a plurality of stainless steel wires 8 are installed inside the concrete layer 2 and are respectively abutted against the bottom of the steel bars 7 at different heights, and a plurality of buffer blocks 10 are installed on the inner bottom of the concrete layer 2.
[0034] During processing, the steel bars 7 and the stainless steel wires 8 are first evenly fixed inside the concrete layer 2. The fixing of the steel bars 7 and the stainless steel wires 8 can effectively improve the tensile capacity of the concrete layer 2, increase the service life of the concrete layer 2, and avoid cracks. At the same time, when the concrete layer 2 is solidifying, the shrinkage joints 6 can ensure that the concrete layer 2 will not produce irregular cracks due to shrinkage during the hardening process and when the temperature drops, so as not to affect the flatness of the road surface. When heavy objects pass through the road surface, the buffer block 10 at the bottom of the concrete layer 2 distributes the pressure to the foundation surface 1, which can effectively buffer the pressure on the road surface, avoid cracks in the concrete layer 2 due to the influence of external forces, and greatly improve the crack resistance of the road surface.
[0035] Refer to the figure Figure 1-Figure 3 A fiber layer 4 is arranged at the bottom of the top surface 3, and the material of the fiber layer 4 is a basalt fiber mesh. A heat-insulating layer 5 is arranged at the bottom of the fiber layer 4, and the material of the heat-insulating layer 5 is a polystyrene foam board.
[0036] The fiber layer 4 made of basalt fiber mesh has the advantages of high tensile strength, large ultimate elongation and good alkali resistance, which can improve the tensile strength, bending resistance, elongation and toughness of the concrete, thereby improving the crack resistance. The thermal insulation layer 5 can effectively eliminate the "thermal bridge" phenomenon inside the concrete layer 2, so that condensation will not occur inside, thereby improving the stability of the concrete layer 2 and avoiding cracking.
[0037] Reference Figure 1-Figure 3 A plurality of steel bars 7 are evenly and symmetrically fixedly connected inside the concrete layer 2, a stainless steel wire 8 is fixedly connected to the bottom of the steel bars 7, the stainless steel wires 8 are crisscrossed in a grid shape, two support plates 9 are fixedly connected between the upper and lower parts of the stainless steel wires 8, the two support plates 9 are cross-fixedly connected to each other, and the two support plates 9 are crossed between the stainless steel wires 8 to form a triangle.
[0038] During processing, the stainless steel wires 8 are crisscrossed and laid at the bottom of the steel bars 7, and the interior of the concrete layer 2 is evenly divided into a grid by the stainless steel wires 8, so as to improve the crack resistance and impact resistance of the concrete layer 2. Secondly, the two ends of the support plate 9 are connected to the stainless steel wires 8 to form a triangular cross support. According to the stability of the triangle, the impact resistance of the concrete layer 2 is greatly improved, and it is more resistant to external impacts, thereby avoiding cracking of the concrete layer 2 after being impacted.
[0039] Reference Figure 1-Figure 3 A buffer block 10 is symmetrically fixedly connected to the bottom of the stainless steel wire 8. The bottom of the buffer block 10 is tightly fitted with the foundation surface 1. The buffer block 10 is in an I-shape, and the length of the upper end of the buffer block 10 is less than the length of the lower end.
[0040] When a heavy object passes through the road surface, the concrete layer 2 will be squeezed toward the buffer block 10 under pressure. When the buffer block 10 is under pressure, the pressure can be distributed to the foundation surface 1 because the upper end length is smaller than the lower end length, which can effectively buffer the pressure on the road surface and prevent the concrete layer 2 from cracking due to the influence of external forces, thereby greatly improving the road surface's crack resistance.
[0041] The implementation principle of the anti-cracking structure of a concrete floor in this embodiment is as follows: when processing, first, the steel bars 7 are evenly fixed inside the concrete layer 2, and then the stainless steel wires 8 are crisscrossed and laid at the bottom of the steel bars 7, and the inside of the concrete layer 2 is evenly divided into a grid by the stainless steel wires 8, so as to improve the crack resistance and impact resistance of the concrete layer 2. Secondly, the two ends of the support plate 9 are connected to the stainless steel wires 8 to form a triangular cross support. According to the stability of the triangle, the impact resistance of the concrete layer 2 is greatly improved, and it is more resistant to external impact, so as to avoid the concrete layer 2 from cracking after being impacted;
[0042] Then, concrete is filled inside the concrete layer 2 and a top surface 3, a fiber layer 4 and a thermal insulation layer 5 are laid on the top in order from top to bottom. The fiber layer 4 has the advantages of high tensile strength, large ultimate elongation and good alkali resistance, so that the tensile strength, bending resistance, elongation and toughness of the concrete are improved, thereby improving the crack resistance;
[0043] Among them, the "thermal bridge" phenomenon inside the concrete layer 2 can be effectively eliminated by setting the thermal insulation layer 5, so that condensation will not occur inside, the stability of the concrete layer 2 is improved, and cracking is avoided. At the same time, when the concrete layer 2 is solidified, the shrinkage joint 6 can ensure that the concrete layer 2 will not produce irregular cracks due to shrinkage during the hardening process and when the temperature drops, so as not to affect the flatness of the road surface;
[0044] Secondly, when a heavy object passes through the road surface, the concrete layer 2 will be squeezed toward the buffer block 10 under pressure. When the buffer block 10 is under pressure, the pressure can be distributed to the foundation surface 1 because the upper end length is smaller than the lower end length, which can effectively buffer the pressure on the road surface and prevent the concrete layer 2 from being affected by external forces and causing cracks in the road surface, thereby greatly improving the road surface's crack resistance.
