Description

Technical Field

[0001] This application relates to the field of building engineering technology, and in particular to a diamond-hardened floor structure. Background Technology

[0002] Flooring refers to the surface that has been treated using specific materials and processes to achieve a certain level of decoration and functionality. Currently, emery aggregate hardened flooring is widely used in factories, garages, parking lots, and industrial parks. In recent years, the scale of large-area factory buildings has been increasing, leading to extremely high requirements for flooring strength, hardness, flatness, wear resistance, impact resistance, and cleanliness.

[0003] However, existing emery-hardened flooring still has some shortcomings in use, such as cracking. In large high-tech factories, existing emery-hardened flooring may develop surface cracks that affect the appearance of the floor and through cracks that affect the flatness and load-bearing capacity of the floor. Both surface cracks and load-bearing cracks can affect the production and anti-static functions of the factory. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a corundum-hardened floor structure that can effectively prevent the formation of floor cracks.

[0005] According to an embodiment of this application, the emery hardened floor structure includes: a ground base layer, in which reinforcing bars are provided, one end of which extends into the ground base layer and the other end is located outside the ground base layer; a concrete layer, laid on the ground base layer, in which a reinforcing mesh is provided, and the reinforcing bars are fixedly connected to the reinforcing mesh; and an emery layer, laid on the concrete layer, in which a hanging wire mesh is provided, and the upwardly extending portions of the reinforcing bars extend into the emery layer and are fixedly connected to the hanging wire mesh.

[0006] Furthermore, the reinforcing bars are installed in the ground base layer through rebar installation and / or pre-embedding processes.

[0007] Furthermore, the surface of the diamond layer has gaps with a depth of 20mm and a width of 4mm.

[0008] Furthermore, the gaps on the surface of the diamond layer are divided into a 4m×4m grid.

[0009] Furthermore, an epoxy resin topcoat layer is laid on top of the diamond abrasive layer to eliminate shrinkage cracks on the diamond abrasive layer.

[0010] Furthermore, the length of the reinforcing bar extending into the ground base layer is ≥50mm, and the length extending upwards is 40-50mm.

[0011] Furthermore, the concrete layer is made of steel fiber reinforced concrete, which is C30 concrete mixed with steel fibers, wherein the steel fiber content is 10-15 kg / m³. 3 .

[0012] Furthermore, the content of corundum in the corundum layer is ≥5kg / m², of which the content of corundum aggregate is ≥50%.

[0013] Furthermore, there are multiple reinforcing bars, evenly distributed on the ground base layer.

[0014] Furthermore, the reinforcing mesh and the hanging wire mesh are welded onto the reinforcing bars.

[0015] The emery hardened floor structure according to the embodiments of this application has at least the following beneficial effects: the wire mesh is set in the emery layer, which helps to eliminate shrinkage cracks in the emery layer located in the shallow layer of the floor structure; the reinforcing bars extend from the ground base to the concrete layer and the emery layer, and the reinforcing bars fix the reinforcing mesh in the concrete layer and the wire mesh in the emery layer, which supports and fixes the reinforcing mesh and the wire mesh, thereby coordinating the ground base, the concrete layer and the emery layer to work together under the force, so as to reduce the surface stress and cracks in the floor structure caused by the deflection of the ground base.

[0029] Flooring refers to the treatment of existing ground surfaces using specific materials and processes to achieve a certain level of decoration and functionality. Currently, emery-hardened flooring is widely used in factories, garages, parking lots, and industrial parks. In recent years, the scale of large-area factory buildings has been increasing, leading to extremely high requirements for flooring strength, hardness, flatness, wear resistance, impact resistance, and cleanliness. However, existing emery-hardened flooring still has some shortcomings, such as cracking. In large high-tech factories, existing emery-hardened flooring may develop surface cracks affecting the floor's appearance and through cracks affecting its flatness and load-bearing capacity. Both surface and load-bearing cracks can impact the factory's production and anti-static functions.

[0030] The following is for reference. Figure 1 This application describes a diamond-hardened floor structure according to an embodiment of the present application.

[0031] like Figure 1 As shown in the figure, this application discloses a diamond abrasive hardened floor structure, which includes a ground base layer 100, a concrete layer 200 and a diamond abrasive layer 300. It should be noted that the ground base layer 100 in this specification is the original structural layer that has not been constructed, and the diamond abrasive hardened floor structure of this application is formed based on the original structural layer.

[0032] The ground base layer 100 is provided with reinforcing bars 110, one end of which extends into the ground base layer 100 and the other end is located outside the ground base layer 100; the concrete layer 200 laid on the ground base layer 100 is provided with reinforcing mesh 210, the upwardly extending part of the reinforcing bars 110 extends into the concrete layer 200 and is fixedly connected to the reinforcing mesh 210; the diamond abrasive layer 300 laid on the concrete layer 200 is provided with hanging wire mesh 310, the upwardly extending part of the reinforcing bars 110 extends into the diamond abrasive layer 300 and is fixedly connected to the hanging wire mesh 310.

[0033] like Figure 1 As shown, the lowest layer of the emery-hardened floor structure is the ground base 100, above which is a concrete layer 200, and above that is an emery layer 300. A reinforcing mesh 210 is provided within the concrete layer 200. In this embodiment, the reinforcing mesh 210 uses a specification and spacing of φ8@200, meaning the diameter of the reinforcing bars used in the mesh 210 is 8mm, spaced 200mm apart. The reinforcing mesh 210 enhances the tensile strength and bending deformation resistance of the concrete layer 200, reduces the occurrence of through-cracks in the concrete layer 200 caused by deflection changes in the ground base 100 or external loads, prevents macroscopic cracking within the concrete layer 200, and provides load transfer for the concrete layer 200.

[0034] A wire mesh 310 is installed in the abrasive layer 300. In this embodiment, the wire used in the wire mesh 310 has a diameter of 1.2 mm and a spacing of 200 mm between the wires. The wire mesh 310 is formed into a mesh-like structure, which provides micro-constraint to the abrasive layer 300 located in the shallow layer of the floor structure, suppressing micro-shrinkage cracks in the abrasive layer 300. A reinforcing bar 110 is installed in the ground base layer 100. The lower end of the reinforcing bar 110 extends into the ground base layer 100, and the upper end extends out of the ground base layer 100. The upper end of the reinforcing bar 110 extends out of the ground base layer 100 and sequentially extends into the concrete layer 200 and the emery layer 300. The reinforcing bar 110 extends into the concrete layer 200 and the emery layer 300 and is fixedly connected to the reinforcing mesh 210 of the concrete layer 200 and the wire mesh 310 of the emery layer 300. It supports and fixes the reinforcing mesh 210 and the wire mesh 310, and coordinates the ground base layer 100, the concrete layer 200 and the emery layer 300 to work together under the force, so as to reduce the surface stress and cracks caused by the deflection of the ground base layer 100.

[0035] Furthermore, during the initial setting and before the final setting of the emery layer 300, emery aggregate is applied to the emery layer 300 in multiple stages. It is understandable that the construction of the emery layer 300 requires the application of emery aggregate, which mixes with the mortar and solidifies to form a high-hardness emery layer 300. Before the mortar solidifies, the aggregate will deposit to the lower layers of the emery layer 300 under gravity. Uneven aggregate distribution will cause localized low hardness in the emery layer 300, making it prone to cracking. To ensure that the aggregate is evenly distributed in the emery layer 300, it is applied in multiple stages during the initial setting and before the final setting to avoid uneven distribution.

[0036] It is understandable that the steel mesh 210 is laid with a specification and spacing of φ8@200, but other reasonable specifications and spacings can also be used; the wire mesh 310 can also be set with other reasonable specifications and spacings.

[0037] In some specific embodiments of this application, the reinforcing bars 110 are installed in the ground base layer 100 by means of rebar installation and / or pre-embedding. That is, the reinforcing bars 110 are tightly connected to the ground base layer 100 by rebar installation or pre-embedding, preventing the reinforcing bars 110 from falling off the ground base layer 100. After the reinforcing bars 110 are fixedly connected to the reinforcing mesh 210 of the concrete layer 200 and the wire mesh 310 of the corundum layer 300, the structural integrity between the concrete layer 200, the corundum layer 300 and the ground base layer 100 is enhanced. The reinforcing bars 110, which are tightly connected to the ground base layer 100, can effectively transfer stress, make the floor structure uniformly stressed, resist various loads, and reduce the risk of cracks and damage.

[0038] In some specific embodiments of this application, the surface of the diamond abrasive layer 300 has gaps with a depth of 20 mm and a width of 4 mm. Furthermore, the gaps on the surface of the diamond abrasive layer 300 are divided into a 4m × 4m grid. That is to say, by making shallow cuts on the surface of the diamond abrasive layer 300 according to a 4m × 4m grid, the shrinkage stress on the surface of the diamond abrasive layer 300 can be released, preventing irregular cracking of its surface.

[0039] In some specific embodiments of this application, an epoxy resin topcoat layer 400 is laid on top of the diamond abrasive layer 300 to eliminate shrinkage cracks on the diamond abrasive layer 300. That is, after the diamond abrasive layer 300 is constructed, an epoxy resin topcoat layer 400 is applied on top to eliminate shrinkage cracks caused by the solidification of the diamond abrasive layer 300. The epoxy resin topcoat layer 400 has good wear resistance, corrosion resistance, and antistatic properties, which not only provide good protection for the floor structure but also meet the antistatic requirements of some factory buildings.

[0040] In some specific embodiments of this application, the length of the reinforcing bar 110 extending into the ground base layer 100 is ≥50mm, and the length extending upward is 40-50mm.

[0041] In some specific embodiments of this application, the concrete layer 200 is made of steel fiber reinforced concrete, which is composed of steel fibers and C30 fine aggregate concrete, wherein the content of the steel fibers is 10-15 kg / m³. 3 This type of concrete composition helps to improve the tensile strength and crack resistance of the floor structure.

[0042] In some specific embodiments of this application, the diamond content in the diamond layer 300 is ≥5kg / m², wherein the diamond aggregate content is ≥50%.

[0043] In some specific embodiments of this application, such as Figure 1 As shown, there are multiple steel bars 110, which are evenly arranged on the ground base layer 100. In other words, multiple steel bars 110 are evenly distributed in the emery hardened floor structure. The evenly distributed steel bars 110 can effectively disperse and bear various loads from above the floor structure. At the same time, it is also convenient to pour and spread the concrete layer 200 and the emery layer 300, making the density of the concrete layer 200 and the emery layer 300 more uniform, and further improving the crack resistance of the floor structure.

[0044] In some specific embodiments of this application, the reinforcing mesh 210 and the wire mesh 310 are welded to the reinforcing bar 110. It is understood that the reinforcing mesh 210 and the wire mesh 310 can also be connected to the reinforcing bar 110 by other fixed connection methods, such as bolts, sleeves, or wire binding. In this specific embodiment, welding is used to fix the reinforcing mesh 210 and the wire mesh 310 to the reinforcing bar 110.

[0045] The following describes the construction method of this floor structure in detail, using the example of a corundum hardened floor structure. First, the ground base 100 is treated, mainly involving removing the laitance layer and rough surface, and cleaning the ground base 100 with clean water. Then, using a rebar anchoring process, rebars 110 are vertically inserted into the ground base 100. The length of the rebar 110 inserted into the ground base 100 is no less than 50mm, and the overhang length is between 40-50mm. The spacing between each rebar 110 is 1000mm. Subsequently, a steel mesh 210 and a wire mesh 310 are laid. The steel mesh 210 is placed approximately 10mm above the ground base 100, and the wire mesh 310 is placed approximately 30mm above the steel mesh 210. The steel mesh 210 and the wire mesh 310 are connected to the rebars 110 by welding, using steel fibers with a content of 10-15kg / m². 3Steel fiber reinforced concrete is poured to form a concrete layer 200. The pouring process employs a segmented pouring technique, with shrinkage joints between the segments to reduce stress and cracks caused by temperature changes and overall water loss shrinkage. The steel fiber reinforced concrete consists of steel fibers and C30 fine aggregate concrete. Further, during the initial to final setting period of the concrete, mortar is lifted and corundum is applied multiple times. The corundum aggregate content is ≥50% of the total corundum. In this embodiment, corundum is applied twice, once during initial setting and once before final setting. Two-thirds of the corundum is applied during initial setting, and the remaining one-third is applied during final setting. Ultimately, the corundum and mortar form a corundum layer 300, achieving a certain thickness. With a diamond content ≥5kg / m², the wire mesh 310 is placed on the diamond layer 300, which helps to eliminate shrinkage cracks in the shallow layer of the floor structure. After the diamond layer 300 has set for 24 hours, shallow cuts of 20mm deep and 4mm wide are made on its surface according to a 4m×4m grid to release the shrinkage stress on the surface of the diamond layer 300 and prevent irregular cracking. Finally, an epoxy resin topcoat is applied to form an epoxy resin topcoat layer 400 to eliminate shrinkage cracks caused by the solidification of the diamond layer 300. The epoxy resin topcoat layer 400 has good wear resistance, corrosion resistance and antistatic properties, which not only provides good protection for the floor structure, but also meets the antistatic requirements of some factories. The reinforcing bar 110 is used to fix the reinforcing mesh 210 in the concrete layer 200 and the wire mesh 310 in the corundum layer 300, providing support and fixation for the reinforcing mesh 210 and the wire mesh 310. This coordinates the ground base 100, concrete layer 200, and corundum layer 300 to work together under stress, thereby reducing the surface stress and cracks in the floor structure caused by the deflection of the ground base 100.

[0046] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
