Description

Assembly type of terrazo stairs

The present invention relates to a prefabricated Tarrazo of the staircase to prefabricated the stair foundation of a building constructed of concrete.

Normally, the stair foundation of a concrete building is finished by the wet method or the 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 until the molten mortar is completely cured after pouring mortar, and when laying artificial mortar, the surface of each of the horizontal and vertical surfaces of each layer is smooth after curing. Grinding is very difficult and difficult has been pointed out as the biggest problem in construction.

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 mixed with cement of natural marble or crushed stone of natural marble is mixed with synthetic resin, and then molded into a mold using a synthetic resin mortar made of kneaded material, and then the surface is smoothly polished. There is a terrazzo.

Since the natural marble plate is produced by cutting natural marble raw material to a certain thickness, the price is very expensive, and terrazzo manufactured using natural marble crumbs belongs to a very low price. Therefore, construction companies, such as natural marble crumbs are mixed, the situation is choosing to finish the stairs with terrazzo, which 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. Because it is thin, it is virtually impossible to grind, so all four sides of the terrazzo are not polished. In addition, when the terrazzo was demoulded from the manufacturing mold, the thickness of the four sides is uneven and uneven, so as a way to eliminate such irregularities, the terazzo is formed slightly larger than the standard, and then the predetermined width of the four sides is cut with a cutting knife. Terrazzo is manufactured by means of making the cut surface a flat cross section.

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.

However, recently, when constructing a staircase of an apartment or the like as a prefabricated terrazzo, since the stairs are constructed without forming a water barrier on the railing side cross sections of the horizontal and vertical terrazzo that protrude toward the railing side of the stairs, the stairs cannot be exposed to the railing side of the stairs. It is pointed out that the horizontal and vertical terrazzo cut-off surface damages the whole aesthetics of the stairs.

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. On the other hand, while concealed, the other cut surfaces 201 and 301 facing the railing side are exposed as they are, and the cut surfaces 201 and 301 exposed to the handrail side of the stair foundation 100 are as described above. The horizontal terrazzo 200 and the vertically polished and polished marble marbles are colored not only smoothly but also because the colors of the marble particles appear bluish, so that the flat surface is simply formed. Compared to the surface of the terrazzo 200, it gives a completely different feeling, which has been pointed out as a problem that harms the whole aesthetics of the stairs.

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 The purpose is to make the exterior of the stairs beautifully by preventing the cutting surface from being formed at the end surface of the railing of the rail and also to form a water barrier without covering the mortar layer on the railing surface of the horizontal and vertical terrazzo. It was designed for a different purpose.

The present invention as a means for achieving the above object,

In the horizontal and vertical terrazzo finishing the horizontal and vertical plane of the stair foundation,
