Abstract

PURPOSE:To improve the efficiency of the execution of work by placing a piece of nonwoven fabric with hard rough particles attached on, on a work- executing surface, to apply liquid-like adhesives from the upper section of the nonwoven fabric, and by impregnating the nonwoven fabric uniformly with the adhesive, to permit the adhesives to come to the work-executing surface and to harden the adhesives. CONSTITUTION:Glass grains or corundum-or-the-like hard rough particles l are temporarily stopped on the nonwoven fabric 2 of plastic fibers or the like with adhesives sprayed on. After that, the nonwoven fabric 2 with the rough particles l attached on is placed on a work-executing surface 3, and the liquid- like adhesives 4 is applied from the upper section of the fabric 2, and the fabric 2 is uniformly impregnated with the adhesives 4. Then, the liquid-like adhesives 4 passes spaces between the hard rough particles l and spaces on the nonwoven fabric 2 and comes to the work-executing surface 3 and acts to permit the work-executing surface 3, the fabric 2, and the hard rough particles l to come in contact with each other. After that, the adhesives 4 is left as it is till it is hardened, and the execution of work is completed. As a result, the work can be easily executed even on the rugged work-executing surface.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an anti-slip construction method, and is particularly suitable for forming an anti-slip layer in a small area or locally, and is suitable for construction with uneven surfaces. This invention relates to an anti-slip construction method that can be easily applied to surfaces.

[Prior Art] It is known to use paint resins mixed with aggregate and the like in order to provide anti-slip properties to building floors, sidewalks, stairs and other surfaces on which people walk. For example, Japanese Patent Publication No. 52-39643 describes that the surface of a floor tile is made non-slip by forming an epoxy resin layer in which hard coarse particles are dispersed on the surface of the floor tile.

By the way, surfaces that have been treated with such anti-slip properties have uneven surfaces, easily attract dirt, and are generally unsightly. Anti-slip construction is often applied partially or locally.

Conventionally, when performing partial or local anti-slip construction, the following methods have been adopted. That is, first, a mask sheet having openings of a required size is placed on the surface to be constructed, and a resin solution containing anti-slip aggregate is applied or poured into the openings of this mask sheet. After this resin is cured, the mask sheet is removed.

The above conventional method has the following drawbacks.

■ It is necessary to place a mask sheet on the surface to be constructed, and it requires a lot of work such as smoothing with a trowel, resulting in poor construction efficiency.

It is relatively difficult to accurately position the mask sheet.

■ ■ It is difficult to form a coating film of uniform thickness, and it is difficult to form a construction surface with uniform thickness and shape.

■ As mentioned above, it is difficult to precisely form the position, thickness, shape, etc. of the anti-slip coating, so the anti-slip properties of the applied surface may be uneven, or there may be unevenness on the surface. You may stumble while walking. Also, the appearance is bad.

As an anti-slip construction method that solves these problems and can easily and efficiently form an anti-slip surface with good anti-slip properties and a good appearance, even when performing anti-slip construction partially or locally, The present applicant has proposed an anti-slip construction method characterized by placing a thin plate-like porous molded body obtained by bonding hard particles with a resin on a construction surface, impregnating the molded body with a resin liquid, and then curing the molded body. first applied for a patent (patent application 1986-14)
No. 9849. Hereinafter referred to as "prior application". ).

[Problem D to be solved by the invention] According to the method of the above-mentioned prior application, it is possible to perform anti-slip construction very easily, but since a rigid formed thin plate is placed on the construction surface, it is difficult to perform construction with unevenness. There is a problem that the surface is not suitable. That is, if the rigid thin plate has irregularities on the construction surface, it will not conform well to the surface and sufficient adhesion strength will not be obtained. For this reason, it is difficult to apply the method of the prior application to uneven construction surfaces.

It is an object of the present invention to provide an anti-slip construction method that eliminates the problems of the prior application and allows easy and efficient anti-slip construction even on uneven construction surfaces.

[Means for Solving the Problems] The anti-slip construction method of the present invention is characterized by placing a nonwoven fabric to which hard coarse particles are attached on a construction surface, applying a liquid adhesive on top of the nonwoven fabric, and curing the adhesive. do.

The present invention will be explained below with reference to the drawings.

FIGS. 1(a) to 1(e) are cross-sectional views showing one method of implementing the present invention.

When carrying out the method of the present invention, first, a nonwoven fabric 2 to which hard coarse particles 1, which are antislip aggregates, are adhered, as shown in FIG. 1(a), is prepared.

As the hard coarse particles 1 used, glass particles, corundum (
Examples include crystalline alumina material), silicon carbide material, and silica sand. Among these, glass grains give a sense of transparency to the construction surface and are excellent in appearance. In addition, corundum is
Due to its excellent wear resistance, it is effective for construction surfaces that are subject to a lot of foot traffic. If the particle size of these hard coarse particles is too small, the effect of improving the anti-slip property will be low, and if the particle size is too large, the adhesion strength to the nonwoven fabric will be low. Therefore, in the present invention, the hard coarse particles are
The average particle size is about 0.2 to 1.0 mm, especially 0.5 m.
It is preferable that it is about m.

The type, particle size, and usage amount of the hard coarse particles are appropriately determined depending on the amount of walking on the construction surface and the required characteristics.

On the other hand, the nonwoven fabric 2 may be any material as long as it has excellent durability, and is not particularly limited, but normally, a nonwoven fabric made of transparent fibers such as plastic fibers and glass fibers is suitable.

A simple and advantageous method for attaching the hard coarse particles 1 to such a nonwoven fabric 2 is to spray an adhesive onto the nonwoven fabric and then scatter the hard coarse particles onto the adhesive.

As a result, the hard coarse particles 1 are temporarily fixed to the nonwoven fabric 2 by point adhesion with the adhesive. In addition, as an adhesive,
An adhesive used for adhering the nonwoven fabric to the construction surface, which will be described later, can be suitably used.

Next, as shown in FIG. 1(b), the nonwoven fabric 2 to which the hard coarse particles 1 are attached is placed on the construction surface 3, which has been subjected to pretreatment such as washing as necessary. Thereafter, a liquid adhesive is applied over the nonwoven fabric 2 to evenly impregnate the nonwoven fabric 2 with the adhesive.

The injection and impregnation of the adhesive into the nonwoven fabric 2 is preferably carried out until the gap between the strings 1a of the nonwoven fabric is filled with the adhesive and a transparent appearance is obtained as a whole.

That is, for example, when the hard coarse particles are glass powder, the particles are white before pouring the adhesive, but become transparent as a whole after pouring the adhesive. White flandum is opaque before the adhesive is poured, but once the adhesive is poured, it takes on an almost transparent appearance as a whole. In this way, the amount of adhesive added can be visually confirmed by the difference in transparency, so by using this transparency as the standard for the amount of adhesive to be injected, it is possible to supply the adhesive with just the right amount. advantageous to

After that, leave it until the impregnated adhesive hardens to complete the installation.

The liquid adhesive passes between the hard coarse particles 1 and further passes through the gaps between the nonwoven fabrics 2 to reach the construction surface 3. As shown in FIG. 1(c), the hardened adhesive 4 reaches the construction surface 3. In addition to playing the role of adhesion between the nonwoven fabric 2 and the nonwoven fabric 2 and the hard coarse particles 3, it also acts as a binder between the hard coarse particles 3. By applying the adhesive in this manner, the nonwoven fabric 2 easily adapts to the surface shape of the uneven construction surface and adheres firmly to the surface, thereby forming a good anti-slip surface.

In the present invention, the liquid adhesive used for construction includes:
It may be a room temperature curing type, a thermosetting type, an ultraviolet curing type, a -wave type, or a two-part type. In the case of a thermosetting resin, it is heated and hardened by applying hot air or the like. Additionally, in the case of emergency construction, etc., it is also possible to use a method that hardens in a few seconds using an ultraviolet curable adhesive. Specific examples of adhesives used include acrylic silicone resin, epoxy resin, and acrylic resin.
Examples include resins, urethane resins, unsaturated polyester resins, fluororesins, etc., and the appropriate one is selected depending on the site conditions, ie, the amount of foot traffic, sunlight hours, etc.

Note that the adhesive used for adhering the hard coarse particles to the nonwoven fabric and the adhesive used for adhering the nonwoven fabric to the construction surface may be of the same type or different types.

The anti-slip construction method of the present invention is extremely advantageous when forming anti-slip surfaces partially or locally in various places such as anti-slip strips on platforms, anti-slip strips at the tips of stair treads, and other places such as parks and roads. In particular, when applied to anti-slip construction on uneven construction surfaces, extremely excellent effects can be obtained. Of course,
It goes without saying that the method of the present invention can also be applied to forming an anti-slip surface over a flat and wide area.

[Function] The anti-slip construction method of the present invention can be easily carried out by simply placing a nonwoven fabric to which hard coarse particles have been attached in advance on the surface to be constructed and applying a liquid adhesive thereon. This nonwoven fabric can be easily positioned, and no mask sheet is required. Moreover, since the hard, coarse particle-adhered nonwoven fabric can be made to have a uniform thickness, the anti-slip layer can also be formed to have a uniform thickness.

Moreover, since the hard, coarse particle-adhered nonwoven fabric conforms well to the surface shape of the construction surface by pouring the adhesive, it is possible to perform good anti-slip construction even on uneven construction surfaces.

[Example] The present invention will be described in more detail with reference to Examples below.

Example 1 The following materials were used as hard coarse particles, an adhesive, and a nonwoven fabric. After spraying hard coarse particles on a nonwoven fabric whose surface was spray-coated with an adhesive, the adhesive was cured to obtain a hard coarse particle-attached nonwoven fabric. Ta.

Hard coarse particles fffi order Nigarasu powder Average particle size: 500 μm Amount used: 0.4 g Adhesive type Niacrylic adhesive Amount used: 0.01 g per 1 crn' area of nonwoven fabric Nonwoven fabric type: Polypropylene fiber Nonwoven fabric size: 3. Oca+x 3. Ocmx O, 2mm
The obtained hard, coarse particle-adhered nonwoven fabric was placed on an uneven construction surface, and the same adhesive as above was applied from above at a rate of 0.2 g per fern' area. After the adhesive was injected, the entire surface became transparent, so the injection was completed and the adhesive was left to stand at room temperature for 6 hours to harden.

The formed anti-slip layer strongly bonded to the uneven shape of the construction surface, and was also found to have extremely high durability.

[Effects of the Invention] As detailed above, according to the anti-slip construction method of the present invention, (1) Since no mask sheet is used, the number of work steps is reduced and construction efficiency is improved.

■ Positioning is easy and the accuracy of the formation position of the anti-slip surface is improved.
