Description

[Detailed Description of the Invention] Industrial field of application This invention relates to the installation of indoor equipment around water such as a unit bath and a prefabricated prefabricated bath in a bathroom or the like to be renovated in an existing building. The present invention relates to a formwork for forming a drainage gradient on a floor, which is convenient for forming a drainage gradient on a floor.

2. Description of the Related Art Generally, when installing indoor equipment around a water supply in an existing building, for example, when installing a unit bath or a prefabricated bath in a bathroom, etc., make sure that the drain hole of the indoor equipment and the existing drain hole of the existing building are in communication. Needless to say, it must be constructed, but the floor of the indoor equipment must be provided with a drainage gradient so that water concentrates in the drainage holes. However, it is difficult to match well the existing drainage hole with the drainage hole of the indoor equipment, and to make the water flow concentratedly in the drainage hole, even if it is possible in design, but it is difficult in the actual construction site. That is. Therefore, usually, the floor of the indoor equipment is provided with an appropriate inclination toward the drain hole depending on the intuition and experience of the worker. Then, connect a flexible pipe such as a bellows pipe to the drainage hole and bend or cut it appropriately according to the situation of the site to insert it into the existing drainage hole for communication and eliminate the trouble of on-site construction work. ing.

However, in order to provide an appropriate slope to the floor of the indoor equipment toward the drain hole, plywood with a flat floor is used as the core material, and resin material or the like is used on the front and back surfaces for waterproofing. This is difficult because it is applied and the tile is attached to the upper surface.

In view of the above circumstances, the present invention allows the existing drainage hole and the drainage hole of the indoor facility to communicate with each other accurately, simply, quickly, and easily, and the water is concentrated in the drainage hole. The purpose of the invention is to provide a mold for forming a floor drainage gradient that can flow.

Means for Solving the Problems In order to solve the above problems, the present invention is intended to form a floor part of an indoor facility or the like having a drain hole that should communicate with an existing drain hole of an existing floor part of a building or the like. A formwork for forming a floor surface drainage gradient having a square pyramidal base with a square bottom was constructed.

Effect According to the above configuration of the present invention, the apex of the truncated pyramid is regarded as the position of the drainage hole, and the core material made of a predetermined plywood or the like for forming the floor along the ridge line concentrated at the apex is cut off and formed. , Connect the cut-off parts, and fix them by inclining them toward the drain hole along the connection part.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a form 1 for forming a floor surface drainage gradient according to the present invention. The form 1 has a bottom of approximately 5 m each.
It is a square frustum of a square shape and is made of plywood or a metal plate, and the inside is hollow. Each surface 2 has an appropriate inclination angle so that a worker can climb it, and the ridgeline 3 thereof.
The apex 4 where water is concentrated can be regarded as the position of the existing drainage hole.
The bottom dimension is not limited to 5 m.

Therefore, an example of manufacturing the floor of the indoor equipment by using the above-mentioned form 1 will be explained. In advance, the floor of the bathroom or the like to be rehabilitated in the existing building is confirmed, and the position of the existing drainage hole is confirmed. The floor of the indoor equipment to be placed on the floor is made of core material. Mark the location of the existing drainage holes on the core material. Then, as shown in FIG. 3, plywood 5 serving as a core material
Is carried and placed on the upper part of the mold 1, and the vertex 4 and the mark 6 of the existing drainage hole are aligned with each other so that each side of the plywood 5 is parallel to each side of the formwork 1 Face 2
Fix it so that it does not move by touching. Therefore, as shown by the phantom lines in FIG. 2, the plywood 5 is separated from the other three surfaces 2. Therefore, the plywood 5 is cut along the four ridges 3 with a saw or the like. For example, in FIG. 3, if the plywood 5a is fixed to the surface 2a, first the ridge line
Cut off part a along 3a and 3b. That is, ridgeline 3a
The ridge line 3b and the ridge line 3b are respectively cut toward the mark 6 (vertex 4). Next, the cut surface cut along the ridgeline 3b is placed along the ridgeline 3b, and the vertex 4 and the mark 6 are
And the remaining plywood 5a is fixed to the surface 2b, and the portion B is cut off along the ridgeline 3c. Then, the remaining part of the plywood 5a is cut along the ridgeline 3c, and the part is cut along the ridgeline 3c.
Cut off two parts of c and d along 3d. Finally, the cut-off part of D is placed along the ridgeline 3d along the c-side, and the mark 6 and the apex 4 are fixed together on the surface 2d. ) Is cut off. The extra part that has been cut off is made antiquated as a piece of wood. As shown in FIG. 4, the plywood 5a is divided into four substantially triangular portions a, b, c and d. Therefore, in order to form the apexes (the portions where the marks 6 were marked) of the respective portions a, b, c and d as drainage holes, the drainage holes 7 having a square shape are cut off to form the drainage holes 7. Match the marks 6 to the vertices 4 on the form 1 on each of the parts of the sheet, and the part of a on the surface 2a, the part of b on the surface 2b, the part of c on the surface 2c, and the part of d. Are placed on the surface 2d and the portions cut along the ridgeline 3 are aligned with each other and connected to each other by a connecting plate 8 made of an elongated metal plate piece.
B, C and D are inclined toward the drainage hole 7 and fixed appropriately. Then, as shown in FIG. 6, a synthetic resin material 9 such as FRP is coated on the front and back surfaces of the plywood 5a for waterproofing.
Tile 10 is stretched on the upper surface. The tiles 10 on the connecting lines of the parts a, b, c and d form joints along the lines. Further, the perforated plate 11 is fitted in the drain hole 7 without leaving the tile 10 attached. Therefore, this floor 12
The indoor equipment is manufactured by using, and the indoor equipment is carried into the existing floor such as a bathroom to be repaired, and the drain hole 7 and the existing drain hole are aligned and fixed on the existing floor. In addition, since the floor of the indoor equipment is placed and fixed directly on the existing floor, the distance between them is only a few cm, so the angle of inclination of each of the parts a, b, c, and d is small. Will not be damaged, and since the joint is along the cutting line, there will be no inconvenience regarding drainage.

As for the floor drainage gradient forming frame 1, the plywood 5 serving as the core material is placed on each surface 2 and cut along each ridge line 3 as described above. In the same manner as described above, the lines intersecting the ridgelines 3 around the marks 6 are drawn with black ink without performing cutting work, and the plywood 5 is placed elsewhere. You may make it cut | disconnect along a line. That is, the formwork 1 may be used as a ruler.

Effect of the Invention According to the present invention described above, a bottom of a square pyramid having a square bottom is formed in order to form a floor of an indoor facility or the like having a drain hole that should communicate with an existing drain hole of an existing floor of a building or the like. Using a table, the apex is regarded as the position of the drain hole, and the plate-shaped core material that serves as the floor of the indoor equipment is applied to the inclined surface and fixed,
By cutting off the parts located on each surface along each ridgeline, it is possible to manufacture a drain hole that matches the existing drain hole and a floor part with a slope for drainage toward that drain hole,
In addition to being simple, quick, and easy to form, it will bring about cost reduction, and it will also be possible to prevent inconvenience and inconvenience of drainage when installing a prefabricated bath when renovating an existing bathroom.
