Description

[Detailed Description of the Invention] The present invention relates to a non-slip device for buildings that is attached to the tips of mortar stairs to protect the corners of the stairs and to prevent falling accidents when going up and down.

Conventional anti-slip devices for buildings have an L at the tip of the stairs.
The letter-shaped anti-slip metal fittings are fixed with adhesive or clasps, but if the product is moved up and down violently, the adhesive may peel off, the clasps may loosen, and the cleats may float up or fall off. There was a problem that it was making it difficult to go up and down the stairs. In addition, some stairs are often formed with the leading end protruding forward in order to increase the area of the tread, but in stairs constructed in this way, the nose of the step is easily damaged, and the conventional L-shaped The type of anti-slip material did not provide sufficient protection.

The present invention eliminates these drawbacks of the conventional technology,
The anti-slip can be firmly attached to the stairs, and can be used even on stairs that have to be climbed up and down frequently.It can also be used on the tip side of the stairs, which is the most dangerous and prone to damage when going up and down, that is, the nosing and risers of the stairs. The purpose is to provide anti-slip structures for buildings that provide protection and an excellent appearance.

The structure of the present invention will be explained based on the embodiment shown in the attached drawings. Reference numeral 1 denotes a non-slip frame material made of a metal such as aluminum alloy or a molded material such as hard synthetic resin. The edge 3 hangs down, and a horizontal bottom wall 4 extends from the lower end of the front edge 3.
The upper surface of the flat plate part 2 is provided with an upwardly directed non-slip fitting groove 5, and the lower surface thereof is provided with an engaging groove 6 that opens downward. An upward engaging groove 7 is provided in the upper surface of the bottom wall part 4 parallel to the flat plate part 2 and extends in the longitudinal direction similarly to the engaging groove 6 of the flat plate part 2.

The anti-slip part 8 has uneven strips 9 formed on its upper surface and is provided on the upper surface of the flat plate part 2 of the anti-slip frame material 1.
A non-slip part 8 made of a flexible synthetic resin or the like is fitted into a fitting groove 5 formed in the fitting groove 5 in a replaceable manner. This anti-slip part 8
As shown in the figure, a plurality of them may be provided so that they can be partially replaced, or as shown in FIG. 4, they may be formed integrally or integrally with the flat plate portion 2 in advance.

Reference numeral 10 denotes an anchor member, which is made of a metal such as steel that is easy to weld, and has locking pieces 12 and 13 extending horizontally from the upper and lower ends of the substantially vertical main body 11, respectively. As shown in the figure, the upper and lower locking pieces 12 and 13 are slidably engaged in the engagement grooves 6 and 7 of the non-slip frame material 1, respectively, and fixed to the non-slip frame material 1 by appropriate means such as screws. At the same time, the main body portion 11 is fixed to the reinforcement 14 of the mounting base B by welding.

To explain the construction method of the anti-slip A of the present invention, the anchor member 10 locked to the anti-slip frame material 1 is slid to position the reinforcing bars 14 planted at appropriate intervals on the mounting base B. At the same time, the anchor member 10 is fixed at that position with screws or the like, and the anchor member 10 is welded and fixed via reinforcing bars 15. Next, with the anti-slip A fixed at the mounting position, mortar 16 is injected into the inside of the anti-slip frame material 1 to form a staircase, and by finishing the tread surface, the anti-slip frame material 1 is attached to the corner of the staircase. Installed and fixed as one piece.

Furthermore, the surface finishing material 17 is applied to the non-slip frame material 1.
The anti-slip A of the present invention is attached to the rear edge of the stairs in a continuous manner to finish the stairs.

The present invention has the above-mentioned configuration,
A flat plate portion is attached to the tip of the stair tread portion near the nosing, and a front edge portion covering the riser of the stair is suspended from the tip of the flat plate portion. A bottom wall portion covering the underside protrusion of the riser of the stair is formed integrally with the lower end of this front edge portion and parallel to the flat plate portion. Locking pieces formed on the upper and lower ends of the anchor member are slidably engaged in engagement grooves formed in the underside of the flat plate portion and the upper surface of the bottom wall portion, and the vertical main body portion is fixedly attached to the reinforcement of the mounting base. The anti-slip device is firmly attached to the tip of the staircase in a covering manner, allowing it to be used for a long period of time even on stairs with frequent ascents and descents.

In addition, unnecessary unevenness is not formed on the nosings and risers of stairs, which are often scratched or hit when going up and down, which protects the safety of people going up and down, and prevents the objects being carried. Damage to the stairs can be prevented.
