Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, specifically to a waterproof and corrosion-resistant epoxy resin flooring structure. Background Technology
[0002] Epoxy resin flooring is widely used in various large venues, offering advantages such as seamless construction, waterproofing, corrosion resistance, dustproofing, easy maintenance, and low upkeep costs. Traditional epoxy resin flooring structures typically consist of a reinforced concrete foundation, an epoxy mortar layer laid on the foundation surface, and topcoat or anti-corrosion paint applied as needed.
[0003] During foundation laying, air bubbles are easily generated inside the concrete, requiring the use of a concrete vibrating table for compaction. The thicker the concrete, the longer the compaction time, and the more difficult it is to expel the internal air bubbles. During later curing or use, water seepage can easily cause blistering in the epoxy mortar layer; therefore, the thickness of the concrete foundation is usually no more than 10cm. Consequently, existing epoxy resin flooring structures have limited impact resistance; severe impacts can easily damage the anti-corrosion paint coating and epoxy mortar layer, thus affecting their service life.
[0004] Furthermore, existing epoxy resin flooring has limited functionality and poor decorative properties, making it difficult to meet the diverse functional and aesthetic needs of different applications. Therefore, there is an urgent need to develop a new type of epoxy resin flooring structure to improve the waterproofing, corrosion resistance, impact resistance, and decorative properties of the flooring, thereby extending its service life and meeting practical application requirements.
[0005] Chinese patent CN109610779A discloses a waterproof and corrosion-resistant epoxy resin flooring structure. It describes embedding a steel mesh within a reinforced concrete base layer, with spring layers on both the upper and lower sides of the mesh. Above the reinforced concrete base layer, a first epoxy mortar layer, an epoxy resin reinforcing layer, a second epoxy mortar layer, and an anti-corrosion paint coating are sequentially laid. While this patent improves the waterproof and corrosion-resistant performance of the flooring, the internal structure of the epoxy resin reinforcing layer still needs further adjustment to enhance its strength and rigidity. Summary of the Invention
[0006] The purpose of this invention is to solve the problems of limited concrete foundation thickness, poor impact resistance, and poor decorative properties in the prior art. Therefore, to solve the above problems, this invention provides a waterproof and anti-corrosion epoxy resin flooring structure, including a reinforced concrete base layer. A load-bearing layer, a first epoxy mortar layer, a second epoxy mortar layer, and a waterproof and anti-corrosion coating are sequentially laid on top of the reinforced concrete base layer. An epoxy resin reinforcing layer (35) is bonded between the first epoxy mortar layer (30) and the second epoxy mortar layer (40). A layer of carbon fiber cloth (65) is disposed inside the epoxy resin reinforcing layer (35). Laying the carbon fiber cloth (65) as an independent layer with specific thickness in the flooring structure can effectively disperse stress, significantly improve the overall tensile and compressive strength and stiffness of the flooring, thereby improving impact resistance.
[0007] Furthermore, the carbon fiber cloth (65) has rectangular through holes (66) arranged in an array on its surface, which can help the internal air bubbles to escape.
[0008] Furthermore, to enhance the decorative effect of the flooring, decorative layers such as colored sand layer and putty layer can be applied above the second epoxy mortar layer. The colored sand layer can be made by mixing colored sand of different colors with epoxy resin, and the putty layer can be made by mixing epoxy resin with putty powder.
[0009] Furthermore, to enhance the bonding and adhesion between layers, reinforcing mesh fabrics, such as fiberglass mesh fabrics or nylon mesh fabrics, can be installed between the layers.
[0010] A steel mesh is embedded inside the reinforced concrete base. Multiple springs or air bladders are set on the upper and lower sides of the steel mesh. One end of the spring or air bladder is fixedly connected to the steel mesh. For easy connection, the spring or air bladder can be fixedly connected at the node of the steel mesh. The springs or air bladders can be arranged in an array or in a grid structure.
[0011] A load-bearing layer is laid between the reinforced concrete base layer and the first epoxy mortar layer. The material of the load-bearing layer can be one or more of high-strength concrete or reinforced concrete.
[0012] By setting carbon fiber cloth in the epoxy resin reinforcement layer of the floor structure, the strength of the floor structure can be enhanced and its impact resistance can be improved. Laying a colored sand layer on the second epoxy mortar layer can significantly improve the aesthetics of the floor structure. Attached Figure Description

[0025] The image forming apparatus provided in this utility model embodiment will be described in detail below with reference to specific embodiments. Example
[0026] like Figure 1 The waterproof and corrosion-resistant epoxy resin flooring structure shown includes a reinforced concrete base layer 10, a load-bearing layer 20, a first epoxy mortar layer 30, a second epoxy mortar layer 40, a colored sand layer 45, and a waterproof and corrosion-resistant coating 50.
[0027] like Figure 3 and Figure 4 As shown, a steel mesh 11 is embedded inside the reinforced concrete base layer 10. The steel mesh 11 is composed of multiple steel bars arranged in a longitudinal and transverse manner to form a grid structure. For example, the longitudinal and transverse steel bars are arranged at a spacing of 10cm-20cm and are perpendicular to each other. It can also be a grid structure arranged diagonally. Regardless of whether it is arranged in a longitudinal and transverse manner or diagonally, all its intersections are welded into a grid structure.
[0028] Furthermore, multiple springs 12 arranged in an array are provided on the upper and lower sides of the steel mesh 11. One end of the spring 12 is welded to the node of the steel mesh 11, and the springs 12 are all embedded inside the reinforced concrete base layer 10.
[0029] Furthermore, the thickness of the reinforced concrete base layer 10 is 12cm to 18cm, and a load-bearing layer 20 is laid on the upper surface of the reinforced concrete base layer 10. The load-bearing layer 20 is made of high-strength concrete and has a thickness of 5cm.
[0030] Furthermore, a first epoxy mortar layer 30 is laminated and bonded to the upper surface of the load-bearing layer 20. The first epoxy mortar layer 30 is made of epoxy resin mortar, which is made by mixing epoxy resin, quartz sand and glass fiber in a mass ratio of 3:5:2 and uniformly dispersing it in the first epoxy mortar layer 30. The thickness of the first epoxy mortar layer 30 is 3mm to 5mm. As is well known, epoxy resin, quartz sand and glass fiber are all high-molecular materials that can enhance strength. When they are mixed and dispersed in the first epoxy mortar layer 30 as part of the floor structure, they can enhance the strength of the floor and thus improve the compressive strength of the floor structure.
[0031] Furthermore, a second epoxy mortar layer 40 is laminated and bonded to the upper surface of the first epoxy mortar layer 30. The second epoxy mortar layer 40 is made of epoxy resin mortar, which is a mixture of epoxy resin, quartz sand, and polyurethane particles in a mass ratio of 2:6:2, and is uniformly dispersed within the second epoxy mortar layer 40. The thickness of the second epoxy mortar layer 40 is 3mm to 5mm. As is well known, epoxy resin, quartz sand, and polyurethane particles are all high-molecular materials with anti-corrosion properties. Their mixture and dispersion in the second epoxy mortar layer 40, as part of the flooring structure, provides anti-corrosion protection.
[0032] In this embodiment, as Figure 2 As shown, more importantly, an epoxy resin reinforcing layer 35 is bonded between the first epoxy mortar layer 30 and the second epoxy mortar layer 40. The epoxy resin reinforcing layer 35 contains carbon fiber cloth 65, which is a carbon fiber cloth 65 with through holes 66 arranged in an array of rectangular holes. The thickness of the epoxy resin reinforcing layer 35 is 3mm. The carbon fiber cloth 65 is a sheet-like structure with high strength and rigidity. Adding it to the epoxy resin reinforcing layer 35 as part of the floor structure can significantly improve the strength of the floor structure, thereby enhancing its impact resistance.
[0033] In this embodiment, as Figure 2 As shown, a colored sand layer 45 is laminated and bonded to the upper surface of the epoxy mortar layer 40. The colored sand layer 45 is made by mixing red, yellow, and black colored sand with epoxy resin in a mass ratio of 6:4, and has a thickness of 2mm to 4mm. Laying colored sand of various colors as the colored sand layer 45 on the upper surface of the second epoxy mortar layer 40 can improve the aesthetics of the floor structure.
[0034] In this embodiment, the upper surface of the colored sand layer 45 is also coated with a waterproof and anti-corrosion coating 50. The waterproof and anti-corrosion coating 50 is made of epoxy anti-corrosion paint and has a thickness of 0.2mm to 0.5mm. Coating the upper surface of the colored layer 45 with the waterproof and anti-corrosion coating 50 can further improve the corrosion resistance of the floor structure and extend its service life.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
