Description

[Detailed Description of the Invention] The present invention relates to a decorative material for stairs that is applied over the surface of foundation concrete in staircase construction to enhance the decorative effect.

In stair construction, tiles and natural stone slabs are generally used as stair decoration materials to cover the basic concrete surface, but dimensional accuracy is required when overlaying with tiles or natural stone slabs. requested,
Furthermore, it takes time and effort to finish the joints between the riser and the nosing and the joints between the riser and the tread in an attractive manner, resulting in an increase in construction costs.

The present invention was completed with the aim of solving the above-mentioned problems and providing a decorative material for stairs that is easy to walk on. The nosing plate part 2 is stretched continuously in the rear direction, with the angle formed by the front surface of the riser plate part 1 and the upper surface of the step nosing plate part 2 being an acute angle of about 80 degrees, and the bottom part of the riser plate part 1 is On the edge, a short eave plate part 3 is stretched in a series in the front direction so that its upper surface forms an acute angle of about 80° with the front surface of the riser board part 1, and It is characterized in that the angles formed between the back surface of the plate part 1 and the bottom surfaces of the nosing plate part 2 and the short eave plate part 3 are all right angles.

In the figure, 4 indicates an appropriate number of anti-slip grooves that are drilled in the left and right directions on the upper surface of the nosing plate part 2 as necessary, and 5 indicates a groove that is transparent in the left and right direction in the upper part of the riser board part 1 as necessary. Weight-reducing communication holes are provided; 6 is a groove that is drilled in an appropriate number in the left and right direction as necessary on the bottom surface of the nosing board 2 in order to increase the adhesion of mortar etc. to the concrete foundation; 7 is a groove; Similar to 6, this is a recessed step section provided laterally in the left and right direction at the rear of the bottom of the short eave plate section 3 in order to increase the adhesion to the concrete foundation.

With this structure, a bonding material such as mortar is applied to the treads and risers of a pre-constructed basic concrete toy during outdoor or indoor stair construction, and then the bonding material is applied to the riser surface. If the back side of the riser board part 1 is joined through the upper edge of the riser board part 1, the nosing board part 2 is continuously stretched rearward on the upper edge of the riser board part 1, so that the front of the upper tread surface or The nosing part is covered by the nosing plate part 2, and at the same time, the inner part of the lower tread is covered by the short eave plate part 3 which is stretched forward from the lower edge of the riser part 1. Then, all that is left to do is to attach an ordinary ceramic board between the short nose plate 3 that covers the upper surface of the back of each tier and the tier nose plate 2 that covers the front upper surface of each tier. This means that it is possible to perform cladding work on stairs that have been cladded with cladding, and the work does not require any special effort or skill, and the construction cost can be reduced.

Moreover, the riser board part 1, the nosing board part 2, and the riser board part 1
Since the and difficulty level plate part 3 are both made of ceramics molded in a series and have no seams, a good-looking finish can be obtained and there is no fear that the nosing part will come off during use.

In addition, because the angle between the front surface of the riser board 1 and the upper surfaces of the nosing board part 2 and the difficulty board part 3, which are stretched in series on the riser board part 1, is an acute angle of about 80 degrees, The width of the tread has been significantly expanded, making it easier to walk on.Furthermore, the angles formed by the back surface of the riser board section 1 and the bottom surfaces of the step nosing board section 2 and the short nose board section 3 are all right angles. When covering the foundation concrete surface with mortar, etc., it will be properly adhered and reliable construction can be easily performed.

However, in order to manufacture such stair cladding materials, it is sufficient to form the base material using an extrusion molding method similar to that used for manufacturing wet tiles and clay pipes, and then dry and fire it using conventional methods.
It also has the advantage of being mass-produced at low cost.

Therefore, the present invention solves the problems associated with conventional staircase construction using concrete, and has great practical value as a decorative material for stairs that are easy to walk on.

Claims (1)

[Scope of utility model registration request] The nosing board part 2 is attached to the upper edge of the riser board part 1 made of ceramic material, with the angle formed by the front surface of the riser board part 1 and the top surface of the nosing board part 2 being an acute angle of about 80 degrees, and the rear direction is continuous. At the same time, a short eave plate part 3 is attached to the lower edge of the riser plate part 1 so that its upper surface forms an acute angle of about 80° with the front surface of the riser plate part 1 so that it extends forward. The decoration for a stage is characterized in that the angles formed by the back surface of the riser board part 1 and the bottom surfaces of the step nosing board part 2 and the short eave board part 3 are all right angles.
