Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a filling material that is fitted into a non-slip fitting frame for buildings that is used by being fixed to the tip of a stair tread. The present invention relates to a non-slip filler for buildings to prevent expansion and contraction, and particularly to a filler that can increase strength and durability.

Conventionally, this type of non-slip filling material for buildings uses vinyl chloride resin and other synthetic resin materials, so during the use process, the filling material hardens, shrinks, softens and expands, especially due to temperature changes. This creates a gap between the filler and the metal fitting frame to which the filler is fitted, which not only impairs the aesthetic appearance, but also prevents sewage and dust from entering from the shrunken sides. This was an extremely dangerous situation, as it could cause the stair to come off the fitting frame, and was even more dangerous from the standpoint of ensuring the safety of stair users. Therefore, the present inventor buried a rigid material made of aluminum or newum coated with a synthetic resin film within the longitudinal wall thickness of a synthetic resin material having a plurality of uneven grooves on one surface, and fixed and integrated the material. We have already provided technologies such as non-slip filling materials for buildings to prevent expansion and contraction.

The present invention makes further improvements to the technology developed by the inventor, and provides a non-slip filler that is more excellent in both durability and strength for frequently used stairs.

In other words, in the case of non-slip products in which rigid materials are embedded and integrated, for example, when stainless steel foil, copper strips, etc. are embedded and integrated in synthetic resin, in frequently used stairs,
Due to the strong treading force during lifting and lowering, compression cracks repeatedly occur in the base material at both ends of the stainless steel foil, steel strip, etc. (see Figure 5). Furthermore, if aluminum foil or the like is used, the aluminum foil surface may be destroyed and the effect of preventing expansion and contraction may not be obtained. Furthermore, during the manufacturing process, when rigid materials are slittered to a desired width, slitter burrs may occur on both cut ends, or irregularities or waves may appear on the surface of the base material. It contained various shortcomings and problems.

The purpose of the present invention is to correct all the drawbacks and problems that tend to occur in the manufacturing process and usage process of non-slip fillers for buildings to prevent expansion and contraction, which are made by embedding and integrating rigid materials, and the gist thereof is as follows. In a base material made of synthetic resin having a plurality of uneven grooves on the upper surface, the upper part of the base material is made of a wear-resistant resin such as urethane,
One or more foam layers are provided within the longitudinal wall thickness of this base material, and a rigid material made of aluminum or the like coated with one or more synthetic resin films is buried under the foam layers. This is a non-slip filling material for buildings that prevents expansion and contraction.

Hereinafter, the present invention having such characteristics will be described in detail with reference to the accompanying drawings.

One or more foam layers 3 are provided within the thickness in the longitudinal direction of a base material 2 made of synthetic resin having a plurality of uneven grooves 1 on its upper surface. In the present invention, a resin 8 such as urethane is used which exhibits excellent abrasion resistance for the upper portion of the base material 2, specifically, the portion of the base material 2 that is rubbed against the sole of the shoe during use. The purpose of providing the foam layer 3 within the thickness of the base material 2 is to soften the stepping sensation during use, and at the installation stage, hold both sides of the filler with your fingers and attach it to the metal fitting frame. In addition to what can be done more easily, the following is particularly important when fitting into 5. That is, it is related to the rigid material 4 that is embedded and integrated in order to prevent the filler from expanding and contracting. This foam layer 3 is formed in order to prevent the rigid material 4 from cracking due to tread pressure caused by frequent use, and the foam layer 3 prevents shocks when going up and down. It also ensures safety when going up and down.

The rigid material 4 shown in FIG.
For example, they are made of aluminum, stainless steel, asbestos, etc., but to explain the relationship between the foam layer 3 and the rigid material 4, as is clear from the conventional example shown in FIG. 5, the base material 2 is made of synthetic resin, The various problems described above occur mainly due to the difference in hardness between the rigid material 4 and the rigid material 4 made of various metals. It can be understood that it is important to provide the foam layer 3 on the base material 2 in order to prevent the foam layer 3 from causing so-called chatter in the form of waves or irregularities that tend to occur on the surface.

In the present invention, the foam layer 3 may be formed in a plurality of layers in the longitudinal direction of the base material 2 or in a single layer as shown in FIG. The number of rigid members 4 itself may be singular or plural, but as described above, the foam layer 3 provides cushioning for the constant tread pressure during repeated use without directly applying the tread pressure to the rigid members 4. After the desired effect is obtained, it is necessary to apply tread pressure to the rigid member 4. That is,
In terms of construction, it is important to always make the width of the rigid member 4 narrower than the width of the foam layer 3. FIG. 4 shows a state in which the non-slip filler according to the present invention is fitted into the metal fitting frame 5.

Notches and the like are formed on both longitudinal edges 6 and 7 of the base material 2 in order to facilitate fitting and unfitting with the fitting frame 5 and to prevent it from coming off during use, so that it is integrated with the fitting frame 5. to be dense.

The present invention consists of the above-mentioned structural requirements, and is an inset type non-slip for the purpose of preventing expansion and contraction of the filler, in which a rigid material is embedded and integrated in the longitudinal direction of the filler Murayama thickness, and a synthetic resin coating is applied to the rigid material itself. By using a material coated with , it is possible to achieve a very tight integration with the rigid material embedded within the thickness of the filler during the heating and pressing process that inevitably accompanies extrusion molding. . Additionally, this problem occurred in technology that integrated rigid materials into the base material (1).
Prevention of compression cracks, (2) Prevention of destruction of the rigid material itself, (
3) By configuring the relationship between the rigid material and the foam layer as described above, unevenness or waves on the surface of the base material can be prevented.

It can be solved. In other words, this makes it possible to increase the durability of the non-slip filler as a whole. Furthermore, since the upper surface of the base material is made of a resin with excellent abrasion resistance, significant effects can be expected in terms of durability and the like. As described above, the present invention is not limited to simply providing a non-slip filler for buildings to prevent expansion and contraction, but also exhibits various effects as described above.
