Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a filler that is fitted into a non-slip fitting frame for buildings that is used by being fixed to the tip of a stair tread.

Specifically, a rigid material made of asbestos material, which has a suitable shape that is coated with a synthetic resin film or is not coated, has a small expansion and contraction rate due to temperature differences and has flexibility and elasticity, and is made of a rigid material having a plurality of uneven grooves on the surface. This is a non-slip filling material for buildings to prevent expansion and contraction, which is embedded within the wall thickness in the longitudinal direction of the material and is fixed and integrated.

Conventionally, this type of non-slip filling material for buildings uses vinyl chloride resin and other synthetic resin materials, so the filling material hardens and shrinks and softens and expands due to temperature changes. The filling material does not create a gap between the metal fitting frame and the fitting frame, which impairs the aesthetic appearance, and also prevents the intrusion of sewage and dust from the contracted ends. This was an extremely dangerous situation from the standpoint of ensuring the safety of stair users.

Many techniques have already been provided in order to solve the drawbacks and problems included in the conventional techniques. However, when considered from a technical standpoint, there are many problems, and the current situation is that a product with sufficient product value has not yet been provided. For example, in the old days, Jikko Sho 6-16001
In the No. 1, there is a J-sleeve stopper in which a wire mesh or perforated plate is interposed within a rubber plate and a piece of cloth is attached to the back side. The intervening barrel of the board makes the whole structure solid and maintains its form, and even when it is attached to the stairs, it becomes a wire mesh core and has the effect of preventing it from coming off when nailing. It stops at . Furthermore, Japanese Patent Publication No. 50-14454 provides a technology in which a non-slip filler is fitted into a non-slip fitting frame for buildings, with a rigid band-shaped plate integrally interposed in the longitudinal direction of the inside. has been done. According to the description in the detailed description of the invention in the specification, the term "rigid strip plate" refers to "reinforced plastics impregnated with metal or fiberglass, etc." However, even if such a rigid band-shaped plate such as a metal plate can be integrally interposed during extrusion molding, it is technically insufficient to firmly integrate the two, and the applicant As expressed by Yama et al., expansion of the filling material cannot be prevented unless both ends of the rigid strip plate are left long and are bent and hooked to both ends of the fitting base. If there are any drawbacks, then the technology is insufficient, and it can be said that no countermeasures have been added to the technology to deal with the shrinkage of the filler in winter. . Furthermore, Japanese Patent Publications No. 50-17765 and Japanese Patent Publication No. 49-41855 also state that ``a sliding plate in which a rigid band-like plate having acute hook-shaped pieces on both lateral edges is embedded integrally in the longitudinal direction inside the filling material is disclosed. Stopper filler j, ``Anticiper filler with an integrally interposed expansion/contraction prevention strip made of one or more linear bodies'', ``A bar-shaped filler with numerous uneven stripes in the longitudinal direction of the outer circumferential surface. "An anti-slip filling material in which an anti-expansion strip consisting of a body is integrally interposed in the longitudinal direction."
, ``An edge-preventing filler that integrally interposes an expansion/contraction prevention strip made of a rod-shaped body with a number of recesses on the outer circumferential surface in the longitudinal direction'', [An expansion/contraction prevention strip made of a spiral body] A non-slip filler j that is integrally interposed in the longitudinal direction of the inside of the container has been announced. However, what is common to all of these conventional technologies is that the embedding of anti-expansion materials having various appropriate shapes within the thickness of a non-slip filling tool made of synthetic resin such as vinyl chloride resin itself is difficult. I don't think it's a mistake.

However, interposing the anti-expansion material inside the synthetic resin filler does not immediately mean that the two are completely fixed and integrated. That is, it can be said that this has no direct connection to preventing expansion and contraction. Furthermore, even if attempts are made to increase the bonding area with the synthetic resin filler by giving the anti-expansion material a variety of shapes as in the prior art,
This alone will never increase the anti-expansion effect. In an extrusion molding machine, an anti-expansion material is interposed inside the filling material, and even though it appears temporarily integrated when extruded, it is difficult for both to be attached to the stairs during construction. are usually completely separated.

Therefore, the present inventor investigated the root cause of the problems of the prior art as described above by fixing and bonding a non-slip filling material for buildings and an anti-expansion material buried and integrated inside the non-slip filling material. As a result of intensive research in search of the cause of the blockage, we developed a rigid material made of aluminum that prevents expansion and contraction.
By coating with a synthetic resin film, the bond between the aluminum material and the synthetic resin filler is made extremely tight.
We have already provided a technique that has succeeded in making complete fixation and integration possible and completely preventing expansion and contraction of the entire filling material (Japanese Patent Publication No. 6827, 1982).

The claimed invention is based on the invention developed by himself (Japanese Patent Publication No. 56-1
No. 6827) is further improved. That is,
In place of aluminum used as the rigid material, in the present invention, asbestos material, which has a lower expansion and contraction rate due to temperature differences than synthetic resins and has flexibility and elasticity, is particularly selected for use. The reason for this is that non-slip products for buildings are often used outdoors or in places where shoes are stepped on, and there are many opportunities for them to come into contact with water, dirt, various chemicals, etc. Therefore, the rigid material that is embedded and integrated within the thickness of the synthetic resin filler must be selected and used with due consideration to this purpose.

In the present invention, the asbestos used in particular has remarkable characteristics, for example, asbestos itself is a natural and unnatural mineral fiber, has moisture resistance, and has high mechanical strength, such as tensile strength. This is one of the characteristics of asbestos, and it can be expected to have various effects such as excellent chemical resistance.

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

FIG. 1 shows a base material J showing an embodiment of the present invention, and the base material 1, which is a filler, is a non-slip filler for buildings made of vinyl chloride resin, acrylic resin, urethane resin, synthetic rubber, etc. On its surface, a plurality of uneven grooves 2 for preventing slipping are formed along the longitudinal direction of the filler, and even though the back surface is flat, the U1 grooves are formed along the longitudinal direction of the filler. It may be formed into Forming the recessed grooves has the effect of making it easier to fit the filler into the fitting frame 4 and to enhance the feeling of stepping on it. In addition, notch grooves and the like are formed on both longitudinal edges 5 and 6 of the filler material in order to facilitate fitting and disengaging with the fitting frame 4 and to prevent it from coming off during use. to strengthen the integration of In the present invention, the so-called "fit-in type non-slip" filler having such a shape is coated or coated with a synthetic resin film as shown in FIG. 2 in the longitudinal direction. A rigid member 3 made of asbestos material is buried and fixed and integrated. In this case, whether or not to apply a synthetic resin film to asbestos can be selected depending on the width, thickness, and hardness of the non-slip filler itself, and whether or not it is possible to choose whether or not to apply a synthetic resin film to the asbestos depends on the width, wall thickness, and hardness of the non-slip filler itself. This is to make it perfect. The reason why asbestos is selected and used as the rigid material 3 is that when it is buried within the thickness of the filler, for example, in the case of a plate-shaped rigid material 3, it has a thickness of about 0.05 mm. things are used,
When such asbestos is used, it is more easily deformable than iron plates, etc., so the product is rolled up with a take-off machine immediately after extrusion using an extrusion molding machine. It is easy to do this, and it is possible to maintain a completely fixed and integrated state in which separation of the resin used as a filler and asbeth 1 is no problem at all. Also, when installing on stairs,
Even in the cutting process that is inevitably required, cutting is made much easier than when using an iron plate or the like. Furthermore,
The shape of the rigid material 3 may be appropriately selected from plate-like shapes, linear shapes, rod-like shapes, spiral shapes, etc., as long as it can be embedded within the longitudinal wall thickness of the filler material. FIG. 3 is a cross-sectional view showing the plate-shaped rigid asbestos board 3 shown in FIG. 2 embedded in a base material or "φ filling material," and FIG. Indicates the state in which

The present invention consists of the above-mentioned structural requirements, and includes embedding a rigid material in the longitudinal direction within the thickness of the filler in an inset non-slip for the purpose of preventing expansion and contraction of the filler.
In particular, asbestos is selected as the rigid material.

Furthermore, by using asbestos itself coated with a synthetic resin film as necessary, it can be embedded within the thickness of the filler material during the heating and pressing process that inevitably accompanies extrusion molding. Asbestos cutting and rigid material are very tightly integrated, and asbestos is used instead of steel plate as a material to prevent expansion and contraction, it is difficult to wind up the product after extrusion.
It can be cut very easily, is extremely resistant to heat and chemicals, and can be easily attached to and detached from the fitting frame. The present invention is simply a non-slip filling for buildings to prevent expansion and contraction, such as eliminating the factors that allow sewage and dust to enter due to peeling from the rigid material inside the filling material, which was often experienced in the conventional technology where the material was simply inserted. It is not limited to just the material, but also has secondary effects such as this.
