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. A filler that does not create a gap between the metal fitting frame to which the filler is fitted due to this, which impairs the aesthetic appearance, and also prevents sewage and dust from entering from the contracted ends. This was a very dangerous situation from the standpoint of ensuring the safety of stairs users. Therefore, the present inventor buried a rigid material made of aluminum coated with a synthetic resin film within the longitudinal wall thickness of a synthetic resin material having a plurality of uneven grooves on its surface, and developed a fixed and integrated elastic material. We have already provided technologies such as non-slip filling materials for buildings.

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.

That is, in the non-slip case in which a rigid material is embedded and integrated, for example, stainless steel foil, steel strip plate, etc. are embedded and integrated in a synthetic resin.

In frequently used stairs, compressive cracks repeatedly occur in the base materials on the upper surfaces of both ends, such as stainless steel foils and steel strips, due to the strong treading force when going up and down (see Figure 6). 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 slitting a rigid material into a desired width, if slitter burrs or the like occur on both cut ends,
It has various drawbacks and problems, such as unevenness or wavy appearance on the surface of the base material.

The present invention corrects all the drawbacks and problems that tend to occur in the manufacturing process and usage process of the non-slip filler for buildings to prevent expansion and contraction, which is made by embedding and integrating a rigid material, and also by punching holes in the rigid material itself. This is intended to further strengthen the integrity of the base material and the rigid material. One or more hollow parts are provided, and the lower part of the hollow part is covered with one or more synthetic resin films, or a rigid material made of uncoated aluminum material with appropriate punched holes is buried. This is an integrated non-slip filler for buildings to prevent expansion and contraction.

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

One or more hollow portions 3 are provided within the longitudinal wall thickness of a base material 2 made of synthetic resin and having a plurality of uneven grooves 1 on its upper surface. The purpose of providing the hollow portion 3 within the thickness of the base material 2 is to soften the treading feeling during use, and at the installation stage, hold the side of the filler surface with your fingers and insert the metal fitting frame 51\ In addition to being easier to fit, the following are particularly important. 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. The rigid material 4 shown in FIG. 4 may or may not be coated with a synthetic resin film. This is because, in the present invention, punching holes 8 are formed in the rigid material 4 as appropriate. That is, when the punched hole 8 is formed, the resin related to the base material 2 is filled into the hole 8 during the manufacturing stage, and the integrity of the rigid material 4 and the base material 2 is ensured. However, if the surface of the rigid material 4 is coated, its integrity becomes stronger. Such a rigid material 4 is made of, for example, aluminum, stainless steel, asbestos, etc., but to explain the relationship between the hollow part 3 and the rigid material 4, as is clear from the conventional example shown in FIG. To prevent the various problems described above from occurring due to the difference in hardness between the base material 2 made of resin and the rigid material 4 mainly made of various metals, and also to prevent the occurrence of cracks due to compression fatigue of synthetic resin. It is also important to provide the hollow portion 3 in the filler in order to release into the hollow portion 3 the wavy or uneven so-called chatter that tends to occur on the surface of the base material 2 during the manufacturing process.

In the present invention, the hollow portions 3 may be formed in a plurality of hollow portions in the longitudinal direction of the base material 2 (see FIGS. 1 and 2), or may be formed in a single hollow portion as shown in FIG. 3. The number of rigid members 4 itself may be singular or plural, but as mentioned above, when the pedal pressure is constantly repeated during use, the pressure does not directly apply to the rigid member 4, but instead acts as a cushion in the hollow portion 3. After the effect is obtained, it is necessary to apply tread pressure to the rigid member 4.

That is, from the viewpoint of the structure, it is important to always make the width of the rigid member 4 narrower than the width of the hollow portion 3. FIG. 5 shows a state in which the non-slip filler according to the present invention is fitted into a metal fitting frame 5, and shows the longitudinal side edges 6 and 2 of the base material 2.
In order to make it easy to fit in and remove from the fitting frame 5 and to prevent it from coming off during use, cutout grooves and the like are formed in 7 to ensure tight integration with the fitting frame 5.

The present invention consists of the above-mentioned structural requirements, and includes the steps of embedding and integrating a rigid material in the longitudinal direction of the thickness of the filler, and the rigid material itself in the fitting 2/4 degree in slip for the purpose of preventing expansion and contraction of the filler. By using a material coated with a synthetic resin film, it is possible to achieve a very tight integration with the rigid material embedded within the filler wall thickness during the heating and pressing process that inevitably accompanies extrusion molding. You can. In addition, the technology that embeds and integrates rigid materials into base materials (1) prevents compression cracks, (2) prevents destruction of the rigid materials themselves, and (3) prevents uneven or wavy surfaces from forming on the base material surface. This makes it possible to increase the durability of the non-slip filler by preventing the occurrence of slippage. Furthermore, since punching holes are formed in the rigid material, the integrity of the base material and the rigid material is strengthened, and a remarkable effect can be expected in preventing expansion and contraction of the filler material. 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.
