Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a building anti-slip device installed at the nosing of a stairway, and in particular to an interlocking type anti-slip device with a plate thickness of 5m/m or less that is placed on the treads of a stairway. be.

2. Description of the Related Art

As shown in Figure 3, conventionally, the mating type anti-slip for buildings has a metal base with a plate thickness of about 1.0 to 1.5 mm.
A thin-walled non-slip material for buildings is used, in which a filler 1 having a thickness of approximately 3.0 to 4.0 mm is fitted into the material.

[Problem that the idea aims to solve]

On the other hand, in this kind of non-slip building material with a very thin plate, the filler 1 is simply fitted to the metal base 2, which weakens the fitting force and causes the filler 1 to peel off inadvertently during use. There were also problems in that the filler 1 lost its flexibility and its cushioning effect was not sufficiently obtained, accelerating abrasion of the upper surface and resulting in a lack of durability. In particular, in the case of slightly wide anti-slip devices with width dimensions of 50 mm and 60 mm, the above-mentioned problems were even more pronounced. The present invention has been made to solve these problems, and provides a thin-walled non-slip for buildings that can increase the engagement force of the filler and maintain a cushioning effect at the tip. With the goal.

[Means to solve the problem]

According to the present invention, the above object, as shown in FIG. 1 corresponding to the embodiment, includes: a metal base whose locking front edge hangs down from the tip of a horizontal base plate and is fixed to the nosing of a staircase; a flexible filler that fits onto the upper surface of the substrate and is bonded and fixed to the metal base; a thin metal plate is integrally formed along the longitudinal direction of the lower surface of the flat plate portion of the filler; , the total thickness of the flat plate part of the filler and the base plate of the metal base is within 5 m/m, and the lower surface of the tip side of the filler is thick with a downward engaging protrusion protruding. A non-slip device for buildings, in which the engaging protrusion is press-fitted into an upward engaging groove formed on the tip side of the metal base. This is achieved by providing

[Effect]

The present invention requires a flexible, thin-walled filler 1 that can be fitted and bonded to the substrate 2a of the metal base 2 at the same time by integrally forming the thin metal plate 3 on the lower surface of the flat plate portion 1a. The engagement force is maintained, and by press-fitting the downward engaging protrusion 1b into the upward groove 2b formed on the distal end side of the metal base 2 on the lower surface of the distal end side of the filler material 1, the distal end side of the filler material 1 is By increasing the flexibility of the structure, it absorbs the force of collision with the nosing of the stairs, which is likely to occur when going up and down, thereby preventing injury, and the contact path between the downward engaging protrusion 1b and the upward engaging groove 2b. By increasing the length, peeling on the tip side is prevented, and the thickness of the plate is increased to reduce wear on its surface.

【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In Fig. 1, reference numeral 2 indicates a metal base fixed to the nosing of the stairs. Its width dimension is 50 mm, its plate thickness is 1.6 mm, and the upper surface has a fitting recess for press-fitting the filler 1. A groove 20 is formed longitudinally. As shown in FIGS. 1 and 2, the filler 1 to be fitted into the metal base 2 is made of a flexible material such as vinyl chloride resin, and its width is adjusted to match the fitting groove 20 of the metal base 2. 47mm, the board thickness is 3.4mm, and the overall board thickness at the tread part is 5.0mm, and the top surface has anti-slip unevenness to improve the anti-slip effect. A strip 11 is formed. Further, a thin metal plate 3 made of aluminum having a thickness of 0.4 mm is integrally formed along the longitudinal direction of the lower surface of the flat plate portion 1a of the filler 1 during molding.
An adhesive tape is pasted on the back surface of the metal base 2, and when the metal base 2 is fitted, it is fixed by being fitted into the fitting groove 20 on the upper surface of the substrate 2a and bonded. This prevents peeling due to tread pressure and shrinkage of both longitudinal end surfaces after installation. On the other hand, on the back surface of the tip end in the width direction of the filler 1, a downward engaging protrusion 1b is provided vertically leaving an edge 1c, and the tip of the base plate 2a of the metal base 2 is turned into a substantially inverted L.
By bending it into a letter shape and connecting it perpendicularly to the locking front edge 2c, an upwardly directed engaging groove 2b is provided, and the above-mentioned engaging protrusion 1b is fitted into the engaging groove 2b. . Incidentally, reference numeral 30 is a floor finishing material such as a tile laid on the rear edge of this anti-slip.

[Effect of the idea]

As is clear from the above explanation, according to the anti-slip structure for buildings according to the present invention, the necessary engagement force can be maintained by allowing the flexible thin-walled filler to be fitted and bonded to the base plate of the metal base at the same time. By fitting the downward engaging protrusion on the lower surface of the tip side of the filler into the upward groove formed on the tip side of the metal base, the flexibility of the tip side of the filler is increased and it can be lifted and lowered. It is possible to prevent injuries by absorbing the force of collision with the stair nosing, which is often caused by tripping, etc., and by lengthening the contact path between the downward engaging protrusion and the upward engaging groove. , delamination on the distal side can be prevented and surface wear can be reduced.
