Description

  The present invention relates to a splash prevention net that prevents splashing substances such as paint splashes and dusts from splashing outside at a construction site or the like.

  Conventionally, at construction sites such as painting and civil engineering work where painting is performed, in order to prevent liquid droplets such as paint, mist, dust, etc., from being scattered to the outside, An anti-scattering net is stretched around. The scattering prevention net can also prevent scattering of building materials such as bolts.

  In some cases, a mesh sheet for building work having a relatively larger mesh size than the scattering prevention net is used as the scattering prevention net. As a mesh sheet for building construction, for example, a mesh sheet having a set of a plurality of yarns having a woven structure of warp and weft has been proposed (Patent Document 1, Patent Document 2, and Patent Document 3). Since the mesh sheet for building construction has a relatively large opening size, substances less than the size of the opening will pass through the opening, but the scattering prevention net is improved by stacking the mesh sheets for building construction to enhance the scattering prevention function. Can be used as

  When the anti-scattering net is installed in a windy place such as a high place, an opening is required to ensure adequate ventilation so that the scaffold can be prevented from collapsing due to wind pressure. On the other hand, in order to prevent scattering of paint or dust to the outside of the anti-scattering net, a sufficient anti-scattering function cannot be obtained unless the opening is made appropriately small. For this reason, the anti-scattering net is required to satisfy both the anti-scattering function and the air permeability, but it cannot be said that the conventional anti-scattering net sufficiently satisfies both functions.

  Moreover, when the mesh sheet | seat for building construction is laminated | stacked and used, the weight of the whole mesh sheet | seat becomes heavy and the workability | operativity in an attachment operation | work is unpreferable. Furthermore, when the mesh sheet for construction work is used outdoors, the weight of the sheet may be further increased if moisture such as rain is included. In addition, if a small mesh opening is used to enhance the function of preventing the scattering of the mesh sheet for building construction, the effect of preventing the scattering is increased, but the air permeability is lowered and it is easily affected by the wind pressure. .

  The present invention has been made to solve the above-described problems, and is to provide a scattering prevention net that is lightweight, excellent in air permeability, and more reliably prevents scattering of paint or the like to the outside. Objective.

  That is, the first invention comprises a sheet-like base material having a plurality of openings in a mesh shape and having air permeability, and a large number of piles extending from the base material to block a part of the openings, The anti-scattering net, wherein the pile is fixed only on one side of the substrate.

  According to a second aspect of the invention, the pile is fixed to the base material by raising, flocking, weaving, weaving, or a combination thereof. Net.

  Hereinafter, embodiments of the anti-scattering net according to the present invention will be described in detail. The scattering prevention net 100 of the present embodiment ensures that air permeable and scattering substances such as fine droplets such as paint splashes and dusts are scattered from the construction site surrounded by the scattering prevention net 100 to the outside. To prevent. The scattering material to be prevented from scattering may include building materials such as bolts. Further, in addition to the scattering material generated during construction, it may be used as a sandproof net or a snowproof net that prevents the scattering of sand and snow. The scattering prevention net 100 of the present embodiment is characterized in that a part of each opening of a base material having air permeability is closed with a pile.

  FIG. 1 is a schematic view in a plan view of a scattering prevention net 100 of the present embodiment. FIG. 2 is an enlarged schematic view of the opening 3 portion of the scattering prevention net 1 of the present embodiment. The anti-scattering net 100 includes a base material 1 and a pile 2.

  The base material 1 is a net-like base material that constitutes the anti-scattering net 100. The base material 1 has the opening part 3 in order to ensure air permeability.

  The form of the air-permeable base material 1 of the present embodiment is not particularly limited as long as it has a plurality of openings and has air permeability. Examples thereof include fiber structures such as woven fabrics, knitted fabrics, nonwoven fabrics and meshes, and sheets and plates in which through holes are formed by punching. Among them, woven fabrics and knitted fabrics are preferable as those having a scattering prevention function and having air permeability and lightness.

  The material constituting the substrate 1 may be either an organic material or an inorganic material. Even when the substrate 1 is a fiber structure, the material is not particularly limited as long as it has fiber forming ability. Examples of the inorganic material include metal, glass, and ceramics. As the organic material, synthetic fibers, natural fibers such as cotton, hemp, silk, and carbon fibers can be used.

  Specific examples of the raw material (organic material) of the fiber structure that forms the substrate 1 include thermoplastic resins, biodegradable resins, thermosetting resins, elastomers, natural resins, and the like. Examples of the thermoplastic resin include polyethylene resin, polypropylene resin, polystyrene resin, ABS resin, AS resin, EVA resin, polymethylpentene resin, polyvinyl chloride resin, polyvinylidene chloride resin, and polyacrylic resin.

Lacquer or the like can be used as the natural resin.

The scattering prevention net 100 of this embodiment preferably has an air permeability of 100 cc / cm ² / sec or more. If the air permeability is less than 100cc / cm ² / sec, although wind pressure is high received when installed in a high place, if 100cc ^/ cm 2 ^/ sec or more, a high place such as sufficiently ventilated even in windy places Can be ensured. Moreover, it is preferable that the intensity | strength measured according to JISL1096 is 150 N / 5cm width or more for the base material 1 of this embodiment. If the strength of the base material 1 is 150 N / 5 cm width or more, even when the anti-scattering net 100 having the pile 2 of this embodiment is used, there is sufficient strength when receiving wind when installed outdoors. This is preferable because the possibility of breakage can be sufficiently reduced.

  Moreover, in order to provide arbitrary functions, the base material 1 of this embodiment may contain another additive component as a functional material. Examples of the functional material include titanium dioxide as a matting agent, calcium stearate as a lubricant, fine particles such as silica and alumina, hindered phenol derivatives as antioxidants, and colorants such as pigments, stabilizers, dispersants, In addition to additive materials such as infrared absorbers, functional materials such as ultraviolet absorbers, antibacterial agents, antifungal agents, antistatic agents, flame retardants, and various catalysts may be added.

  Next, the pile 2 of this embodiment closes a part of the opening part 3 of the base material 1 as mentioned above. The “pile” in the present embodiment refers to a thin hair-like fiber, and the tip may not be looped or may be looped. 3 is a cross-sectional view of the opening 3 at the position AA in FIG. In FIG. 3, a hair-like pile 2 that is thinner than the yarn of the base material 1 extends from the yarn (fiber) constituting the base material 1.

  The material of the pile 2 is not specifically limited, A well-known thing can be used. Examples include polyamide fibers, polyester fibers, polyethylene fibers, polypropylene fibers, chemical fibers such as rayon and vinylon, natural fibers such as wool, cotton and hemp, and other composite spun fibers. You may use it in combination.

  The structure of each opening 3 of the scattering prevention net 100 will be described. As shown in FIG. 2, the opening 3 is formed by a base material (thread), and a part of the opening is closed by a large number of piles 2 extending from the surrounding base material.

  The phrase “a part of the opening” is blocked by the pile 2 means a structure in which the opening 3 is not completely blocked. Specifically, the openings 3 are covered with the pile 2 so that the openings 3 are not completely blocked and the air permeability is maintained, but fine substances such as liquid droplets such as paint and dust are The opening 3 is in an open state in which the pile 2 is touched and the passage to the outside of the net is prevented.

  Moreover, since the shape of the opening part 3 of this embodiment changes with what is used as the base material 1, it is not specifically limited, For example, if the base material 1 is a textile fabric, a knitted fabric, a mesh, etc., polygonal shapes, such as a rectangle, may be sufficient. . Moreover, if the base material 1 is a sheet | seat by punching processing, arbitrary shapes may be sufficient, for example, a polygonal shape, circular, an ellipse etc. may be sufficient. Moreover, if the base material 1 is a nonwoven fabric, the shape of the opening part 3 is indefinite. In the present embodiment, an example in which the opening 3 has a rectangular shape formed of warp and weft will be described.

  In the present embodiment, the length of the pile 2 that blocks a part of the opening 3 may be appropriately determined based on the size of the opening 3 and the size of the scattering material that is prevented from being scattered by the scattering prevention net 100.

  For example, when the base material 1 is a woven fabric, knitted fabric, mesh, or the like and the opening 3 is rectangular, the length of the pile 2 is ½ or more of the longer side of the opening 3. Is preferred. If the pile 2 is longer than 1/2 of the long side, the opening 3 extends from one of two parallel threads (warp or weft) of the substrate 1 to the other direction as shown in FIG. This is because the extending piles 2 overlap with each other in the vicinity of the center of the opening 3, and it becomes possible to more reliably prevent scattering material smaller than the opening 3. If it is shorter than ½ of the longest part of the opening 3, an area where there is no pile for preventing scattering may occur near the center of the opening 3 of the substrate 1. Therefore, in order to reliably capture a smaller substance, it is preferable that the length of the pile 2 is not less than ½ of the long side of the opening 3.

  In addition, since the opening 3 is covered with the pile 2 and the scattered substance to be captured may be captured by the pile 2, for example, even if some of the piles 2 are shorter than 1/2 of the long side of the opening 3, It is only necessary that the opening 3 is covered by the pile 2 facing the pile 2 or the pile 2 extending in a direction orthogonal to the pile 2 so that a gap larger than the scattered material to be captured is not formed.

  In addition, the size of the opening 3 in the scattering prevention net 100 of the present embodiment is not particularly limited. However, if the opening 3 is used as a scattering prevention net for paint, dust, etc., if the shape of the opening 3 is rectangular, one side The length is preferably 0.5 mm or more and 10 mm or less. Moreover, if it is opening of shapes other than a rectangle, the magnitude | size of the width of an opening part is 0.5 mm or more and 10 mm or less. If the size of the opening is less than 0.5 mm, sufficient air permeability may not be ensured. If the size is larger than 10 mm, the pile will not be able to receive the scattered material, and it will not be possible to prevent scattering to the outside. . In the case of the opening 3 having such a size, the length of the pile 2 is preferably ½ or more of the length of the long side as described above if the opening 3 is rectangular.

  In the present embodiment, the length of the pile 2 that blocks a part of the opening 3 is preferably shorter than the length (opening width) of the opening 3 of the base material. When the pile 2 that closes a part of the opening 3 is fixed by flocking, an adhesive or the like is applied to the entire surface of the substrate 1 when the pile 2 is flocked. This is because the ventilation resistance is increased because two or more piles 2 are closed on the base material 1. When the pile 2 that closes the opening 3 is fixed to the base material 1 at one location, one of the ends of the pile 2 becomes a free end, and thus an increase in ventilation resistance can be suppressed.

  The pile 2 only needs to extend outward while covering the periphery of the yarn of the substrate 1. In consideration of air permeability, the pile 2 that closes the opening 3 is more preferably fixed to one side of the substrate 1. FIG. 3 shows a state in which the pile 2 is fixed on the upper side of the drawing, and the pile 2 is fixed only on one surface side of the scattering prevention net 100. When the anti-scattering net 100 having the pile 2 fixed on one side is used, the surface on which the pile 2 is fixed is directed toward the inside of the construction site where the scattered material is generated, and the pile 2 is not fixed. What is necessary is just to use a processing surface toward the outside of a construction site. As shown in FIG. 3, the scattering material 4 such as paint generated from the inside of the construction site is captured by the pile 2 and is prevented from being scattered outside from the scattering prevention net 100. On the other hand, as shown in FIG. 4, the wind from the outside of the site makes it easy for wind to pass through the pile 2 in the direction in which the wind flows (reduces the wind pressure received), so that sufficient ventilation can be ensured.

  Moreover, it is preferable to block a part of each opening 3 of the base material 1 with the pile 2. This is because if there is an opening 3 that is not blocked at all by the pile 2, the material will scatter from there. In addition, when all the opening portions are blocked by one opening portion 3, the air permeability is lowered. Therefore, it is preferable that each opening portion 3 is partially closed.

  Next, the fixing method of the pile 2 to the base material 1 is demonstrated. In the present embodiment, the pile 2 being fixed to the base material 1 means that the pile 2 extends outward from the base material 1. Therefore, not only the pile 2 fixed to the base material 1 by fixing means such as an adhesive, but also the pile extending from the base material 1 by raising the base material 1 itself, A pile extending from the material 1 is also included, and any pile 2 that is fixed to the base 1 and extends from the base 1 may be used. Specifically, in this embodiment, the fixing method of the pile (fiber) 2 that closes the opening 3 of the base material 1 to the base material 1 may be any method such as raising, flocking, knitting, and weaving. A combination of these may also be used. In these methods, in the case of raising, there is a possibility that the strength of the base material may be reduced, and in the case of knitting or weaving, it takes time for processing, so that flocking is more preferable.

  In this embodiment, the raising method is not particularly limited, and a known method can be used. For example, the emery raising method of fluffing by pressing and roughing a roll with sandpaper attached, the needle of fluffing by applying a fabric with many fine needles and hooking the fibers with the needle Examples thereof include a cloth raising method. The fluffed pile (fiber) may be formed with a loop, the loop may be cut, or the end of the fiber may be pulled out. There may be. Although raising may be carried out on both surfaces of the substrate 1, it is preferable in terms of air permeability that the raising is raised only on one side as described above.

  Moreover, you may raise using the insertion structure | tissue for raising as another raising method. As the insertion tissue, a woven fabric or a knitted fabric may be laminated on the surface to be raised on the substrate, and the insertion tissue may be raised by the raising method described above. Further, the raised tissue is a knitted or woven structure in which a raised yarn is inserted into a base material, and the raised yarn comes out on the surface on the raising surface side, and raised by the raising method. May be. This raising method can suppress a decrease in strength of the base material.

  In this embodiment, the method for flocking is not particularly limited, and a known method can be used, and methods such as electrostatic flocking, spray flocking, and spray flocking can be used. With electrostatic flocking, an adhesive is applied to the surface of the base material 1 in advance, and piles (short fibers) to be flocked (attached) are arranged on the electrode plate, and a high direct current is applied between the base material 1 and the electrode plate. A voltage is applied. For example, when an anode (plus) potential is applied to the base material 1 and a negative (minus) potential is applied to the electrode plate on which the pile is disposed, polarization occurs in the pile, and the negative charge of the pile is attracted to the base material 1 and is planted. Then, the hair is transplanted by mechanically holding the planted state by curing the adhesive. When electrostatic flocking is used, the top end portion of each pile 2 (short fiber) that has been flocked becomes an anode (positive potential), so that the top end portions of each pile 2 repel each other. Each pile 2 in which one hair is planted is planted so as to stand perpendicular to the planting surface.

  In this embodiment, the method of weaving and weaving is not particularly limited, and a known method can be used.

  According to the anti-scattering net 100 of the present embodiment described above, the pile 2 extends from the base material 1 so that minute scattering substances such as sprays and dusts generated from the construction and work sites inside the anti-scattering net 100 can be obtained. The wind from the outside of the anti-scattering net 100 can be easily blown by the pile 2 fixed to the base material 1, and the air permeability is secured so that the influence of the wind pressure can be suppressed. doing. Therefore, according to the scattering prevention net 100 of the present embodiment, it is possible to provide the scattering prevention net 100 that is lightweight and excellent in ventilation.

  Moreover, when it is set as the structure which fixes the pile 2 only to the single side | surface side of the base material 1 in the scattering prevention net | network 100, compared with the case where the pile 2 is fixed to the perimeter of the thread | yarn of the base material 1, the pile 2 comes from the outside. It becomes easy to fly by the wind. Therefore, the structure which fixes the pile 2 only to the single side | surface side of the base material 1 does not fix the pile 2 while the scattering material scattered toward the exterior of a net is reliably caught by the pile 2 of the single side | surface side. Wind can be more easily passed from the surface (external) side. Therefore, according to the said structure, the scattering prevention net | network excellent in the ventilation property can be provided.

(Other embodiments)
Another embodiment of the anti-scattering net 100 will be described. FIG. 5 is a schematic view of the opening 3 portion of the scattering prevention net 100 according to the present embodiment which is another embodiment. In the present embodiment, there is a completely open range where the pile 2 does not exist in the central portion of the opening 3. For example, if the scattering material to be captured is larger than the area of the opening 3 where the pile 2 does not exist, even if it is completely opened as shown in FIG. 5, it is captured by the surrounding pile 2 and scattered outside. Can be prevented. And by setting it as the structure which a part of each opening part 3 is opening completely, air permeability can be improved rather than the case where the pile 2 exists in the whole range of the opening part 3. FIG.

  Therefore, according to the present embodiment, it is possible to provide the scattering prevention net 100 having higher ventilation. For example, when using an anti-scattering net in a strong wind field such as a construction site at a high place, the use of the anti-scattering net 100 of this embodiment can effectively prevent the scattering of scattered substances to the outside. However, the influence of wind pressure can be further suppressed.

  The anti-scattering net 100 according to some embodiments described above is used in various fields, such as for dust scattering prevention in construction and civil engineering construction sites, paint scattering prevention, sand scattering prevention such as ground, and snow prevention sheet. Available.
