The cutting grindstone machine 3 has an optimum cutting edge (not shown) for cutting the surface of the floor H and making deep grooves 5, dust prevention means, water supply means, and the like. Prepare. As an alternative to the cutting wheel machine 3, for example, a cutting wheel machine (including a tipped saw, the same shall apply hereinafter), a grinding wheel machine, a polishing chisel, a cutting chisel, an abrasive polishing machine, etc. (various machines) are possible. However, and not by way of limitation, the present invention relates to the method of installing the flooring hardware, and is not limited to the construction of the machine, its type, or whether it is automatic or manual. In order to facilitate understanding of the invention, various machines will be described as the cutting grindstone machine 3, but are not limited thereto.

Although not shown, on one side 2a of the mullion 2 and the other side 20a of the mulch 20, a manual cutting machine (cutting and grinding machine (chip saw The groove 5 is constructed using a manual tool such as a grinding wheel machine, a polishing chisel, and a cutting chisel. In addition, by securing a flat state by gluing or fixing the metal fittings 6 to the horizontal bottom surface 51 by fixing screws, the adhesion of the water stop plate 10 to the watertight rubber 100 and the water stop to the metal fittings 6 are improved. It is possible to function as a strength member against the water pressure received by the plate 10 and to improve the strength of the water stop/water stop plate 10 . Furthermore, in a structure in which the floor metal 6 is provided with a lid, the lid is erected and used as a surface for contacting the watertight rubber, so that it functions as a strength member against the water pressure received by the above-mentioned water stop plate 10, etc. There is The water stop plate 10 can be attached to the mullions 2 and 20 by either a drop-in type or an insertion type, or by a handle tightening type or other lock type. . Further, although not shown, it is also possible to install the water stop plate 10 in the opening H1 by either a drop type or an insertion type without installing the mullions 2 and 20. FIG.

Then, in FIGS. 5-1 to 5-3, on the floor surface H2 having a thickness of 5 to 25 mm, as shown in FIG. , a groove 5 having a surface width 50 of 30 to 60 mm, the bottom of which is a horizontal bottom surface 51, the groove 5 of the floor surface H2 is applied with an adhesive or a fixing means, and here In the construction of laying the floor metal 6 on the floor, as a rule, the curing period is 0.

In addition, by rotating cutting of the blade portion of the cutting wheel machine 3 or continuous cutting (peeling) work, the shape change and / or dimension change of the groove 5 can be freely changed, which is useful. There is a degree of freedom for openings H1 in various places, and it is effective and beneficial, and can also meet customer's demands.

As shown in the figure, since the conventional floor surface H2 is a pavement made of tiles, crushed stones, or concrete, the floor surface H2 is cut and peeled off with a cutter or the like, and the concrete underneath is scraped off. Scrape to construct a deep recess HH (a deep recess HH as shown in FIG. 6-1 compared to FIG. 5-1 of the present invention). For example, peel off a tile that is about 5 to 6 cm wider than the width of the hardware you want to install, and continue to scrape (for example, continue digging) the floor surface H2 as described later. In addition to the large bending, distortion due to welding (connection, integration), etc., may cause an adverse effect such as changing into, for example, an H shape or a U-shape. It is difficult to predict that, for example, if only the laying metal is used, the bending will be large and distortion will occur in fixing such as welding, and in the worst case, the structure will be H-shaped or U-shaped. Furthermore, in the conventional deep concave portion HH, for example, while mounting fixtures such as driving anchors and/or anchor round bars are installed, the metal fittings are attached, so that the space of the deep concave portion can be filled with mortar and tiled. After finishing, it is necessary to give caution and notice about 2 to 3 days as a curing period. At the same time, problems such as the need for digging, backfilling, and tile finishing processes, as well as the complicated and costly laying hardware, occurred. much needed. In addition, for example, the fixing of the cover lid requires a post-process, which increases the cost, and the need for a post-process to fix the groove-shaped hardware is troublesome (this can be said to be a conventional problem).

However, in the present invention, a deep concave portion HH is constructed by conventional "concrete scraping." In other words, it is a feature that can avoid the harmful effects of changing to an H shape or a U-shape due to distortion caused by welding, etc.," or "Construction days and site curing. In particular, as mentioned above, there is a practical benefit of avoiding the work of removing the tiles, pasting the tiles, etc., and the labor and/or convocation of the craftsmen.

Each structure, feature, and the like described above is a description of a preferred example of the present invention. Therefore, the present invention is not limited to the above-described embodiments, and structures that partially change the configuration, structures that achieve the same features and effects, etc. within the spirit of the invention fall within the scope of the present invention. is.
