However, when a T-shaped or L-shaped shape is used according to the arrangement position and a linear rail is connected to these, workability when the rail 33 is stretched vertically and horizontally as shown in FIG. 5, for example, is shown. Can be raised. Further, in this case, if the end of the rail 33 is fitted with a blanket cap so that the concrete for pouring does not enter, and at least one space for inserting and removing the support is secured, the end of the rail 33 is supported after the concrete is poured. It is possible to add or remove tools freely, and flexibly respond to changes in partitions and reforms.

FIG. 6 is a view for explaining another embodiment of the method for constructing the wall support and the embedding rail of the present invention. As shown in FIG. 6 (a), the deck plate 41 is folded when it is manufactured. And the rail portion 42 is provided. By doing so, the rail of the present invention embedded in the floor slab can be provided only by placing the cinder concrete floor 43 on the deck plate 41 as shown in FIG. 6B.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above embodiment, the support tool is fitted after the rail is embedded, but the support tool may be preliminarily fitted to the rail instead of such retrofitting, and so-called pre-installation may be performed. Needless to say. In addition, FIG. 3 shows an example in which the rail is embedded in the floor slab, but when the rail is used on the floor upper surface, it is used for fixing the rail, and when it is used on the floor lower surface, the support member 22 is tied to the reinforcing bar as a reinforcing material. May be used. Further, the support tool has a cap nut screwed to the tip of the bolt, but may have a band or the like for holding a vipe or duct attached to the tip of the bolt. The rails, supporting members, supporting members, etc. may be made of a material such as synthetic resin instead of metal.

[0017]

As is apparent from the above description, according to the present invention, the tunnel portion forming the sliding space of the support made of the bolt and nut set in the longitudinal direction, the slit portion communicating with the tunnel portion, and the tunnel portion are formed. A rail having a flat section formed at the tip of the slit section and having an Ω-shaped cross section is used, and the flat section of the rail is aligned with the mounting surface so that the rail is embedded in the ceiling, floor, or wall. Since the bolt is passed through and the nut is tightened at the tunnel portion and the flat surface portion to fix the support, if the rail is embedded during concrete pouring, the hanging bolt or the like can be attached at any position along the rail. Also, because it can be moved along the rails, it can be easily retrofitted, and can be easily used for partitions and reforms.

Furthermore, the present invention eliminates the need for a building, wiring and equipment, and makes it easy to attach boards, veneers, etc. to floors, walls, and ceilings, and to shorten the finishing work.
