Description

Technical Field

[0001] The utility model relates to the technical field of artificial lawns, in particular to a protective and reinforced cement-based artificial lawn. Background Art

[0002] In terms of environmental protection and beautification, lawn cultivation is commonly used, such as slope protection, community greening, parking lot greening, etc. However, natural lawn cultivation takes a long time and is easily damaged, so artificial turf has been increasingly used in recent years.

[0003] However, the existing artificial turf is usually simple in structure, such as an environmentally friendly and recyclable artificial turf described in CN217298269U, which includes a turf body, which includes a grass fiber layer, a base fabric layer and a backing adhesive layer. This artificial turf has low strength and is easily deformed and damaged when subjected to force. It is not suitable for some environments that require the turf to have high support strength and high stability, such as parking lots, slope protection, etc. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a protective and reinforced cement-based artificial turf.

[0005] The technical solution of this utility model is as follows:

[0006] A protective and reinforced cement-based artificial turf comprises a base layer and a plurality of grass fiber bundles fixed on the base layer;

[0007] The base layer includes a water-permeable layer, a strengthening filling layer, a gelatin layer and a waterproof layer;

[0008] The water seepage layer is located above the colloid layer and is separated by a preset distance, and a reinforced filling layer is formed between the two. A three-dimensional mesh fabric is arranged in the reinforced filling layer, and a cement mixture is filled in the three-dimensional mesh fabric.

[0009] The grass fiber bundle is U-shaped, and its two upper ends pass through the gelatinous layer, the reinforcing filling layer and the water-permeable layer from bottom to top. The waterproof layer is fixedly connected to the lower surface of the gelatinous layer and covers the lower end of the grass fiber bundle.

[0010] In the above scheme, the water-permeable layer is a fine-mesh woven cloth, so that water can enter the reinforced filling layer through the water-permeable layer and prevent the cement mixture in the reinforced filling layer from flowing out.

[0011] Preferably, the water-permeable layer is woven from high-tenacity threads, and the waterproof layer is made of waterproof cloth.

[0012] The three-dimensional mesh fabric is supported between the water seepage layer and the waterproof layer to support a space filled with cement mixture, and is woven from a plurality of transverse and vertical fiber threads. The plurality of transverse and vertical fiber threads can be arranged in a three-dimensional coordinate axis direction and woven together to form a three-dimensional fluffy mesh structure so that the cement mixture can be filled inside.

[0013] Among them, the upper and lower ends of a number of vertical fiber filaments are woven on the water-permeable layer and the gelatinous layer respectively, so as to further connect the water-permeable layer and the gelatinous layer together and enhance the overall connection strength of the base layer.

[0014] The thickness of the reinforced filling layer is between 10 mm and 30 mm so as to have a higher supporting strength.

[0015] In addition, the cement mixture filled in the reinforced filling layer includes cement, aggregate and solidifying agent, and when filling, it is preferably to use a vibration device to make the cement mixture uniformly filled in the reinforced filling layer.

[0016] The upper surface of the colloid layer of the present application is provided with an adhesive layer, which is used to fix the colloid layer and the hardened cement mixture, thereby fixing the waterproof layer and preventing the waterproof layer from falling off.

[0017] As the grass fiber bundle passes through the gelatinous layer, it is bound to cause holes in the gelatinous layer. By utilizing the elasticity and recoverability of the gelatinous material, the grass fiber bundle is pressed and wrapped when passing through the gelatinous layer, so that there is no gap in the grass fiber bundle and between the grass fiber bundle and the gelatinous layer, thereby preventing water from flowing along the grass fibers of the grass fiber bundle to between the gelatinous layer and the waterproof layer, affecting the connection between the waterproof layer and the gelatinous layer, and preventing the waterproof layer from falling off.

[0018] The material of the adhesive layer can be one of pressure-sensitive adhesive, butyl adhesive or asphalt adhesive.

[0019] The thickness of the gelatinous layer is between 1 and 2 mm.

[0020] In addition, a number of grass bundles are arranged in a horizontal array on the base layer.

[0021] The utility model provides a protective reinforced cement-based artificial turf, which improves the support strength and anti-deformation ability of the artificial turf by arranging a water seepage layer and a waterproof layer and filling a cement mixture between the two.

[0022] In addition, the cement mixture is filled in the three-dimensional mesh fabric, and the fibers of the three-dimensional mesh fabric are solidified with the cement mixture, which further improves the structural strength and compression and tension resistance of the cement mixture, making the artificial turf less prone to damage and having a longer service life.

[0023] In addition, the grass fiber bundles are connected to the base layer in a U-shape, so that there is interaction between the two clusters of grass fibers extending out of the base layer (i.e., the two ends of the grass fiber bundles), providing anti-deformation force, and further improving the structural strength and compression and tension resistance of the artificial turf.

[0028] like Figure 1 As shown, the embodiment of the utility model provides a protective and reinforced cement-based artificial turf, comprising a base layer 1 and a plurality of grass fiber bundles 2 fixed on the base layer 1;

[0029] The base layer 1 includes a water-permeable layer 11, a strengthening filling layer 12, a gelatin layer 13 and a waterproof layer 14;

[0030] The water-permeable layer 11 is located above the colloid layer 13 and is separated by a preset distance, and a strengthening filling layer 12 is formed between the two. A three-dimensional mesh fabric 121 is provided in the strengthening filling layer 12, and a cement mixture 122 is filled in the three-dimensional mesh fabric 121;

[0031] The grass yarn bundle 2 is composed of a plurality of simulated grass yarns, which are fixed on the base layer 1 by acupuncture technology, and the lower end thereof is located below the gelatin layer 13 and is fixedly connected to the gelatin layer 13, and the upper end is located above the water permeable layer 11 and can be spread out to form simulated grass. The simulated grass yarn can be made of PA (polyamide), PP (polypropylene) or PE (polyethylene) material;

[0032] The grass fiber bundle 2 of this embodiment is U-shaped, and the two upper ends of the U-shaped grass fiber bundle 2 correspond to two different positions of the base layer 1 and pass through the gelatin layer 13, the reinforcing filling layer 12 and the water-permeable layer 11 from bottom to top, forming two simulated grasses above the water-permeable layer 11. The waterproof layer 14 is fixedly connected to the lower surface of the gelatin layer 13 and covers the lower end of the grass fiber bundle 2, that is, the lower end of the grass fiber bundle 2 is sandwiched between the gelatin layer 13 and the waterproof layer 14. The U-shaped grass fiber bundle 2 can not only form simulated grass, but also play a role in connecting the various component layers of the base layer 1.

[0033] Furthermore, the water-permeable layer 11, the cement mixture 122, the colloid layer 13 and the waterproof layer 14 are connected into a whole through the three-dimensional mesh fabric 121 and the grass fiber bundles 2, thereby improving the overall structural strength and the compression and tensile deformation resistance of the artificial turf.

[0034] Specifically, the water-permeable layer 11 is a fine-mesh woven fabric, so that water can enter the reinforced filling layer 12 through the water-permeable layer 11, react with the cement mixture 122, and prevent the cement mixture 122 in the reinforced filling layer 12 from flowing out.

[0035] The water-permeable layer 11 is preferably woven from high-tenacity yarn to improve the structural strength and service life of the water-permeable layer 11. The waterproof layer 14 is made of waterproof cloth, which has high tenacity and is easy to cooperate and bond with the colloid layer 13.

[0036] The three-dimensional mesh fabric 121 is supported between the water-permeable layer 11 and the colloid layer 13 to support a space filled with cement mixture 122. The three-dimensional mesh fabric 121 is woven from a plurality of transverse and vertical fiber threads. The plurality of transverse and vertical fiber threads can be arranged in a three-dimensional coordinate axis direction and woven together to form a three-dimensional fluffy mesh structure so that the cement mixture 122 can be filled inside.

[0037] The plurality of transverse fiber filaments and the plurality of vertical fiber filaments may be made of fiber materials such as glass fiber or polypropylene fiber.

[0038] The upper and lower ends of a plurality of vertical fiber filaments are woven on the water-permeable layer 11 and the colloid layer 13 respectively, so as to further connect the water-permeable layer 11 and the colloid layer 13 together, thereby enhancing the overall connection strength of the base layer 1 .

[0039] The thickness of the reinforcing filling layer 12 is between 10 mm and 30 mm, so that the base layer 1 has a higher supporting strength.

[0040] The cement mixture 122 filled in the reinforced filling layer 12 includes cement, aggregate and coagulant, and is initially a solid powder particle mixture, which reacts with water and hardens to form a hard cement structure.

[0041] When filling the cement mixture 122, a vibration device can be used to uniformly fill the cement mixture 122 in the reinforced filling layer 12. The specific composition ratio can be appropriately adjusted as needed, which is a prior art and will not be described in detail.

[0042] An adhesive layer 15 is provided on the upper surface of the colloid layer 13. The adhesive layer 15 is coated on the upper surface of the colloid layer 13 and is used to fix the colloid layer 13 and the hardened cement mixture 122, thereby fixing the waterproof layer 14 to prevent the waterproof layer 14 from falling off. The colloid layer 13 is used to prevent water from penetrating between the colloid layer 13 and the waterproof layer 14 through the grass fiber bundle 2.

[0043] Since the grass fiber bundle 2 passes through the gelatin layer 13, it is bound to cause perforations on the gelatin layer 13. Therefore, by utilizing the elasticity and recoverability of the gelatin material, the grass fiber bundle 2 is pressed and wrapped when passing through the gelatin layer 13, so that there is no gap in the grass fiber bundle 2 and between the grass fiber bundle 2 and the gelatin layer 13, thereby preventing water from seeping along the grass fibers of the grass fiber bundle 2 into the gelatin layer 13 and the waterproof layer 14, affecting the connection between the waterproof layer and the gelatin layer, and preventing the waterproof layer from falling off.

[0044] The material of the glue layer 13 can be one of pressure-sensitive glue, butyl glue or asphalt glue, and the thickness is between 1 and 2 mm.

[0045] In addition, a plurality of grass fiber bundles 2 are arranged in a horizontal array on the base layer 1 .
