Description

Technical Field

[0001] The utility model relates to the technical field of protective nets, in particular to a non-metallic safety protective net. Background Art

[0002] Protective nets are widely used in daily production and life. They can provide safety protection for production and life or engineering construction, such as protection against theft and falling objects, and can also be used for livestock fencing, grain storage and other aspects. Currently, the commonly used safety nets are made of metal materials such as iron wire and wire rope, or plastic. They are heavy in weight, and are labor-intensive to move and install. In addition, they have poor durability during use. They are prone to aging and deformation after 1-2 years of use. If they are not replaced in time, there will be safety hazards. Frequent replacement leads to high costs.

[0003] The patent document with application number CN202011390520.X discloses a geogrid with nested reinforcement belts for a pile net structure, including longitudinal main force-bearing reinforcement belts, transverse main force-bearing reinforcement belts, longitudinal auxiliary force-bearing reinforcement belts and transverse auxiliary force-bearing reinforcement belts. The force-bearing reinforcement belts are all made of polyester fiber bundles. Although this patent is different from the metal mesh and uses flexible materials, if it is used as a protective barrier, it needs to be tied to the column with wire or plastic to achieve an upright state. However, there will be sharp corners or hooks when the wire is tied, and the workload is large and the efficiency is low. Moreover, the safety net structure disclosed in the patent is single, lacks reinforcement structure and anti-deformation structure, and the overall strength is low. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology that the metal protective net has a large specific gravity, poor durability and is easy to deform, while the flexible material has poor fixation, a single structure, and lacks a reinforcement structure and an anti-deformation structure, the utility model provides a non-metallic safety net.

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

[0006] A non-metallic safety net comprises a main body net, the main body net adopts a polymer composite material, the main body net comprises longitudinal reinforcing ribs, transverse reinforcing ribs, longitudinal ribs and transverse ribs arranged in a criss-cross manner; a number of the longitudinal reinforcing ribs are arranged in parallel and coplanar with the longitudinal ribs, and the transverse width of the longitudinal reinforcing ribs is 3-5 times the transverse width of the longitudinal ribs; a number of the transverse reinforcing ribs are arranged in parallel and coplanar with the transverse ribs, and are fixed as a whole on the same side of the longitudinal reinforcing ribs, and the longitudinal width of the transverse reinforcing ribs is 3-5 times the longitudinal width of the transverse ribs; two oblique ribs arranged in an "eight" shape are further provided between two adjacent longitudinal reinforcing ribs; a connecting piece capable of fixing the two is provided at the intersection of the longitudinal reinforcing ribs and the transverse reinforcing ribs; and a fixing belt is also provided on the side of the transverse reinforcing ribs away from the longitudinal reinforcing ribs.

[0007] The longitudinal and transverse reinforcements are arranged in a crisscross pattern to form the main body of the main net. The longitudinal and transverse reinforcements are arranged to play a role in reinforcement and fixing. The width of the longitudinal and transverse reinforcements is 3-5 times the width of the longitudinal and transverse reinforcements, which significantly enhances the overall tensile strength of the main net. The oblique reinforcements arranged between two adjacent longitudinal reinforcements and the connectors arranged at the intersection of the longitudinal and transverse reinforcements can not only further enhance the overall strength of the safety net, but also enhance the overall anti-deformation ability and improve the overall stability. The safety net can be fixed to the column or other supporting structure by the fixing belt, without the need to use wire, which is convenient for installation and disassembly.

[0008] Furthermore, the plurality of longitudinal and transverse reinforcements are arranged at equal distances to ensure the structural stability of the safety net in the longitudinal and transverse directions and maintain a balanced load-bearing capacity.

[0009] Further preferably, the plurality of longitudinal reinforcement ribs and transverse reinforcement ribs are arranged at equal distances to ensure that the safety net has the same reinforcement effect in the longitudinal and transverse directions, thereby ensuring structural stability and force balance.

[0010] Specifically, the interval between the two adjacent and parallel longitudinal / transverse reinforcing ribs is 0.5-1 meter, which can not only ensure the strength of the reinforcing ribs, but also avoid material waste and a significant increase in overall weight due to too dense arrangement.

[0011] Specifically, the connector includes a first connector and a second connector, which are respectively arranged on both sides of the main body net; the first connector is arranged parallel to the transverse reinforcement ribs and is located on the side of the longitudinal reinforcement ribs away from the transverse reinforcement ribs; the second connector is arranged parallel to the longitudinal reinforcement ribs and is located on the side of the transverse reinforcement ribs away from the longitudinal reinforcement ribs. The area of ​​the two connectors is 3 times the area of ​​the intersection of the longitudinal reinforcement ribs and the transverse reinforcement ribs, which can increase the area of ​​the connection and fixation between the longitudinal reinforcement ribs and the transverse reinforcement ribs, enhance the structural stability of the intersection, and avoid tearing.

[0012] Preferably, the fixing belt is provided with a serrated anti-slip rubber strip, through which the safety net can be fixed to a column or other supporting structure, which is convenient for installation and disassembly without the use of wire. The setting of the anti-slip rubber strip on the fixing belt can increase the friction coefficient with the column and reduce the occurrence of sliding.

[0013] As a preferred embodiment, the main body net is made of high-strength polyester fiber material, which has excellent wrinkle resistance and shape retention, and high tensile strength and wear resistance.

[0014] Furthermore, the longitudinal width of the safety net is 2-5 meters, which is convenient for cutting, laying and overlapping. When in use, the width can be selected according to specific needs and application scenarios. The selection range is large, the flexibility is great, and the mesh is easy to store and move.

[0015] As a preferred embodiment, the surface of the safety net is covered with a flame-retardant and antistatic coating, which can avoid the occurrence of fire caused by static electricity generated by friction, improve the fire resistance limit of the overall structure at the same time, and block the spread of fire.

[0016] Through the above design, the beneficial effects of the non-metallic safety net of the present utility model are as follows: the longitudinal reinforcing ribs and the transverse reinforcing ribs are arranged to play a role in reinforcing and fixing, and the widths of the longitudinal reinforcing ribs and the transverse reinforcing ribs are both 3-5 times the widths of the longitudinal bars and the transverse bars, so that the tensile strength of the whole body net is significantly enhanced. The diagonal ribs arranged between two adjacent longitudinal reinforcing ribs and the connecting pieces arranged at the intersections of the longitudinal reinforcing ribs and the transverse reinforcing ribs can not only further enhance the overall strength of the safety net, but also enhance the overall anti-deformation ability and improve the overall stability. The safety net can be fixed on the column or other supporting structures through the fixing belt, without using iron wire, which is convenient for installation and disassembly. The overall structure is stable, with high tensile and anti-deformation strength, high wear resistance, effectively preventing static electricity and fire, and is convenient for overall movement and installation, with high use efficiency.

[0024] Embodiment

[0025] Combined with Figures 1 to 4 , this embodiment provides a non-metallic safety net, including a body net 1, and the body net 1 is made of a polymer composite material.

[0026] As a preferred embodiment, the main body net 1 is made of high-strength polyester fiber material, having excellent wrinkle resistance and shape retention, and relatively high tensile strength and wear resistance.

[0027] Furthermore, the longitudinal width of the safety net is 2 - 5 meters, which is convenient for cutting, laying, and overlapping. When in use, the width can be selected according to specific requirements and application scenarios, with a large selection range and high flexibility, and the netting is convenient for storage and movement.

[0028] As a preferred embodiment, the surface of the safety net is coated with a flame-retardant and antistatic coating, which can avoid the occurrence of fire caused by static electricity generated by friction, and at the same time improve the fire resistance limit of the overall structure and block the spread of fire.

[0029] In this embodiment, the main body net 1 includes longitudinal reinforcing ribs 11, transverse reinforcing ribs 12, longitudinal bars, and transverse bars arranged in a crisscross pattern. A number of the longitudinal reinforcing ribs 11 are arranged parallel and coplanar with the longitudinal bars, and the transverse width of the longitudinal reinforcing ribs 11 is 3 - 5 times the transverse width of the longitudinal bars; a number of the transverse reinforcing ribs 12 are arranged parallel and coplanar with the transverse bars, and are integrally fixed on the same side of the longitudinal reinforcing ribs 11. The longitudinal width of the transverse reinforcing ribs 12 is 3 - 5 times the longitudinal width of the transverse bars. The longitudinal reinforcing ribs 11, longitudinal bars, transverse reinforcing ribs 12, and transverse bars are not coplanar, and no bending occurs at the intersection points, and the strength of the intersection points is not affected, so as to maintain the stability of the tensile strength.

[0030] Furthermore, a number of the longitudinal bars and transverse bars are arranged at equal intervals and have the same width, ensuring the structural stability of the safety net in the longitudinal and transverse directions and maintaining a balanced load-bearing capacity.

[0031] Further preferably, a number of the longitudinal reinforcing ribs 11 and transverse reinforcing ribs 12 are arranged at equal intervals and have the same width, ensuring the same strengthening effect of the safety net in the longitudinal and transverse directions and guaranteeing the structural stability and force balance.

[0032] Specifically, the distance between two adjacent and parallel longitudinal / transverse reinforcing ribs 12 is 0.5 - 1 meter, which can not only ensure the strength of the reinforcing ribs, but also avoid material waste and a significant increase in the overall weight caused by too dense arrangement.

[0033] In this embodiment, there are also two diagonal ribs 13 arranged in a "V" shape between two adjacent longitudinal reinforcing ribs 11. A number of the diagonal ribs 13 are arranged along the length direction of the longitudinal reinforcing ribs 11, and the calculation formula for the number N of the diagonal ribs 13 between two adjacent longitudinal reinforcing ribs 11 is:

[0034] N = 2(n - 1);

[0035] In the formula:

[0036] N is the number of oblique ribs 13 between two adjacent longitudinal reinforcing ribs 11;

[0037] n is the number of transverse reinforcement ribs 12;

[0038] Exemplarily, the oblique rib 13 is located on the side of the transverse reinforcement rib 12 away from the longitudinal reinforcement rib 11, the two ends of the oblique rib 13 are respectively connected to the two adjacent transverse reinforcement ribs 12, and the two oblique ribs 13 are located in the middle of the two adjacent vertical reinforcement ribs, thereby improving the balance of the oblique reinforcement.

[0039] Furthermore, the width and material of the oblique reinforcement 13 are consistent with the width and material of the longitudinal reinforcement / transverse reinforcement, which facilitates production and ensures that the strength of the safety net in all directions is consistent.

[0040] In this embodiment, a connecting piece 2 capable of fixedly connecting the longitudinal reinforcing rib 11 and the transverse reinforcing rib 12 is provided at the intersection of the longitudinal reinforcing rib 11 and the transverse reinforcing rib 12 .

[0041] Specifically, with reference to the connector 2 Figures 3 to 4 The connecting member 2 includes a first connecting piece 21 and a second connecting piece 22 respectively arranged on both sides of the main body net 1; the first connecting piece 21 is arranged parallel to the transverse reinforcing rib 12 and is located on the side of the longitudinal reinforcing rib 11 away from the transverse reinforcing rib 12; the second connecting piece 22 is arranged parallel to the longitudinal reinforcing rib 11 and is located on the side of the transverse reinforcing rib 12 away from the longitudinal reinforcing rib 11. The area of ​​the two connecting pieces is three times the area of ​​the intersection of the longitudinal reinforcing rib 11 and the transverse reinforcing rib 12, which can increase the area of ​​connection and fixation between the longitudinal reinforcing rib 11 and the transverse reinforcing rib 12, enhance the structural stability of the intersection, and avoid tearing.

[0042] In a specific implementation, the longitudinal width of the first connecting piece 21 is consistent with the longitudinal width of the transverse reinforcing rib 12, the transverse width of the second connecting piece 22 is consistent with the transverse width of the longitudinal reinforcing rib 11, and the connecting piece 2 is sewn and connected to the transverse reinforcing rib 12 and the longitudinal reinforcing rib 11 by polyester fiber rope to improve the connection strength.

[0043] In this embodiment, the non-metallic safety net further includes a fixing belt 3 arranged on the side of the transverse reinforcing rib 12 away from the longitudinal reinforcing rib 11 .

[0044] The fixing belt 3 is fixedly connected to the second connecting piece 22 , and the safety net can be tied to a column or other supporting structure through the fixing belt 3 .

[0045] Reference Figure 2, preferably, the fixing band 3 is provided with a serrated anti-slip rubber strip. The safety net can be fixed on the column or other support structures through the fixing band 3, which is convenient for installation and disassembly without using iron wire. The anti-slip rubber strip on the fixing band 3 can increase the friction coefficient with the column and reduce the occurrence of sliding.

[0046] By providing the longitudinal reinforcing ribs 11 and the transverse reinforcing ribs 12, the function of reinforcing and fixing is achieved. Moreover, the widths of both the longitudinal reinforcing ribs 11 and the transverse reinforcing ribs 12 are 3-5 times the widths of the longitudinal and transverse ribs, so that the overall tensile strength of the main body net 1 is significantly enhanced. The diagonal ribs 13 arranged between two adjacent longitudinal reinforcing ribs 11 and the connecting pieces 2 arranged at the intersections of the longitudinal reinforcing ribs 11 and the transverse reinforcing ribs 12 can not only further enhance the overall strength of the safety net, but also enhance the overall anti-deformation ability and improve the overall stability. Moreover, the safety net can be fixed on the column or other support structures through the fixing band 3 without using iron wire, which is convenient for installation and disassembly. The overall structure is stable, with high tensile and anti-deformation strengths, high wear resistance, effectively preventing the occurrence of static electricity and fires, being convenient for overall movement and installation, and having high use efficiency.
