Description

Assembly type of terrazo for stairs

The present invention relates to a prefabricated Terrazo of stairs that prefabricated the stairs of a building constructed of concrete.

The stairs of concrete building are finished by wet method or dry method.

The former wet method is to install the mold on the vertical plane of each floor of the stair foundation, and then install artificial mortar or cement mortar on the horizontal plane and vertical plane respectively. This wet method takes a lot of time and manpower to install the mold on each floor of the stair foundation. It is also necessary to wait for the mortar to be completely cured after pouring mortar, and when laying artificial snow mortar, the surface of each of the horizontal and vertical surfaces of each layer after the curing of the mortar is mortar. It is pointed out that the biggest problem in construction is that the smooth polishing is very difficult and difficult.

And the latter dry method is a prefabricated block-shaped plate manufactured in accordance with the standard of each floor horizontal and vertical surface of the staircase base part as a prefabricated, the above-mentioned block-shaped plate is a natural marble plate made by cutting the natural marble to a certain thickness Wow, the artificial marble mortar kneaded by mixing the natural marble debris or cement mortar or the synthetic resin mortar kneaded with the synthetic resin liquid is molded in the mold and then the surface is smoothly polished. There is a terrazzo.

Since the natural marble plate is composed of natural marble ore, the price is very expensive, whereas terrazzo made of natural marble crumbs belongs to a relatively low price. Therefore, construction companies, such as natural marble crumbs are mixed, the situation is to finish the stairs with a terrazzo that has the same effect as natural marble.

On the other hand, the terrazzo is not only a rough surface in the state formed in the manufacturing mold, but also the color of the artificial stone (crushed stone) does not appear at all, so that the color of each crushed stone distributed on the surface appears clearly and has a smooth surface In order to ensure that the surface is polished by using a polishing machine, the surface is made of a relatively large plane so that polishing can be easily performed, but the thicknesses of the front, rear, left and right sides are approximately 10 to 50 mm. Since it is thin, it is very difficult and difficult to grind, so the thickness part is not polished. In addition, when the terrazzo is demolded from the manufacturing mold, since the four sides are uneven, the terrazzo is manufactured by means of cutting the four sides with a cutting knife so as to make the four sides flat.

However, if the four sides of the terrazzo are cut with a cutting knife, the cuts may be flat, but the cuts are not smooth and the color of the crushed stone is not clear. Compared to this clear surface, it feels completely different.

By the way, the stairs of the apartment etc. which are recently constructed are constructed without the water barrier at the railing side in which the railing is installed.

As an example, in the prior art, which is constructed without a water barrier, as shown in FIG. 10, one end of the horizontal terrazzo 200 and the vertical terrazzo 300 that finish each layer of the stair foundation 100 may have a wall surface (G). ), While the other end cut surfaces 201 and 301 are constructed in the state exposed to the handrail side, and the cut surfaces 201 and 301 are exposed to horizontal and vertical terrado 200 ( The other end of the construction 300 is projected to protrude toward the handrail side of the stair foundation 100, and the handrail structure installed on the stairs is installed as a structure for fixing the handrail pillar 400 to the handrail side wall of the stair foundation 100. have.

However, in the prior art as described above, in the construction of the terrazzo, one side of the cut surface facing the wall surface G of the left and right sides of the horizontal and vertical terrazzo 200 and 300 is closely adhered to the wall surface G. The other side cutting surfaces 201 and 301 which are covered but are directed toward the railing side are exposed, and the cutting surfaces 201 and 301 exposed to the railing side of the stair base 100 are cut by the cutting knife as mentioned above. As the cut state is not smooth and the color of the marble particles appears bluish, it gives a completely different feeling from the surface of the polished horizontal terrazzo 200 and the vertical terrazzo 200, thus damaging the whole appearance of the stairs. It is pointed out.

The present invention has been made to solve the problems shown in the prior art, it is easy to assemble the horizontal and vertical terrazzo finishing the foundation of the staircase, and each of the horizontal and vertical terrazzo exposed to the railing side of the stair foundation It is designed with the purpose of decorating the exterior of the stairs beautifully so that the cutting surface does not appear on the railing side cross section.
