Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) This invention relates to a floor border mounting structure in a large unit room.

(Prior Art) Conventionally, the floor surface of a large unit room is configured using a precast concrete board (hereinafter abbreviated as PC board),
The floor border on which the peripheral wall of the unit room is placed uses two sets of height adjustment bolts as shown in Fig. 4.
It was fixed to the PC board.

The mounting structure of the floor border is that the fixing piece (103) on the lower side of the floor border (102) is fitted to the upper height adjusting bolt (101) driven into the PC board (100), and the bolt (101) is attached. The upper limit height of the fixing piece (103) is limited by the nut (104) screwed into the fixing piece (103), the nut (105) is fixed to the fixing piece (103), and the fixing piece (103) is screwed into the nut (105). Use the lower height adjustment bolt (106) to secure the fixing piece (1
By fixing the lower limit height of 03), the fixing piece (103) can be
The plate (100) is held at a predetermined height from the upper surface.

Then, the height adjusting bolts (101) (106) are provided at predetermined intervals along the floor border and the PC board (100) along the floor border, and these height adjusting bolts (101) (106) are used. By adjusting the height of each part, the levelness of the wall mounting surface (107) of the floor border (102) on which the peripheral wall (108) is mounted is adjusted.

However, in the mounting structure of the floor border as described above, since the fixing piece on the lower side of the floor border is supported in a floating state, the floor border cannot be accurately supported in the vertical state, and thus the unit room is assembled. There were times when it was impossible.

(Technical Problem) The technical problem of the present invention is to support the floor border vertically on the horizontal plane so that the floor border is accurately supported vertically to the PC board.

(Means for Solving the Technical Problem) The means taken by the present invention to solve the above-mentioned technical problem are as follows: A smooth and horizontal screw-in base made of synthetic resin is embedded, the lower side of the floor border is placed on these screw-in bases via spacers, and the lower side is screwed and fixed to the screw-in base. is there.

(Operation) According to the above means, the floor border is placed on the screwing base embedded in the precast concrete board through the spacer so that the lower side portion of the floor border is fixed on the horizontal and smooth upper face of the screwing base. It is held vertically as a reference.

Also, by fixing the lower side of the floor border to the screwing table, the floor border is fixed vertically on the precast concrete board.

(Effect) Since the present invention is as described above, since the floor border can be attached and fixed on the basis of the upper surface of the screwing base which is smooth and horizontal, the floor border can be placed vertically on the precast concrete board. It can be held accurately and the unit room can be assembled accurately and smoothly on the floor border.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The PC board (A) constitutes the bottom wall of the unit room, is shaped and molded in advance at the factory, and a discharge pipe (not shown) for supplying and draining water is arranged on the lower surface thereof.

In the case of this embodiment, the PC board (A) is formed into a square plane as shown in FIG. 2, and at the time of molding, the screw board (a) is installed along the line on which the floor border (1) is installed on the upper surface thereof. 2) is buried.

As shown in FIGS. 1 and 3, the screwing base (2) is a block body having a trapezoidal cross section made of a synthetic resin material such as vinyl chloride, and the top surface of the block body is finished to be smooth and two set screws described later are provided. (3) The lower hole (2a) is formed, and when the PC board (A) is molded, the same base (2) upper surface (2b) is attached to the PC board (A) upper surface (A '). Place it horizontally while burying it.

Further, the screwing base (2) is embedded so that its upper surface (2b) is flush with the upper surface (A ') of the PC board (A) or slightly higher, and the floor border (1) is installed. Three pieces are arranged at equal intervals along each line on the four sides.

By embedding the screw-in stand (2) as described above, the installation range of the unit room is shown, and it also serves as a guide when placing the equipment brought into the site in the proper place on the PC board (A).

The floor border (1), which is attached and fixed along the screw-in base (2) installed as described above, is constructed by stacking the FRP layer (1b) on the inside of the elongated plated steel plate (1a), and the upper side portion thereof is cranked. The mounting surface (1c) on which the peripheral wall (b) of the unit room is mounted is formed by bending in a circular shape, and the fixing piece (1d) that is bent outward is formed on the lower side. .

The fixing piece (1d) has a through hole (1e) for the setscrew (3) at a position corresponding to the prepared hole (2a) of the screwing base (2).

In order to attach the above-mentioned floor border (1) to the PC board (A), the both ends of the four floor borders (1) are cut diagonally so that they can be joined in a frame shape, and then these floor borders ( The fixing piece (1d) of 1) is lined up on the upper surface (A ') of the PC board (A) in parallel with each other, and the ring-shaped spacer (4) is arranged along the upper surface (2b) of each screwing stand (2). Place after interposing.

The spacer (4) is formed to have a thickness of, for example, about 1 m, and the required number of spacers are interposed between each screw-in base (2) and the fixing piece (1d) to increase the height of the fixing piece (1d) in each screw-in base (2). This is to adjust the horizontality of the placement surface (1c) of the floor border (1) accurately (first
(Fig. 3, Fig. 3).

Then, insert the setscrew (3) into each through hole (1e), screw it into the prepared hole (2a) of the screw-in base (2), and tighten it, thereby fixing the fixing piece (1d) to the screw-in base (2). To fix.

In addition, (6) is a tile board, (5) is a sealing material that seals the gap between the lower side of the floor border (1) and the PC board (A) upper surface (A '), and a silicone sealing material or the like is applied. is doing.

Then, the floor border (1) mounts the fixing piece (1d) on the lower side on the surface (2b) with the upper surface (2b) of the horizontal and smooth screwing base (2) as the reference surface. Since it is to be fixed by attaching it, it can be accurately attached to the PC board (A) in a vertical state, and the mounting surface (1c) can be attached by the spacer (4).
The levelness of the unit room (B) can also be adjusted accurately, whereby the unit room (B) can be assembled accurately and smoothly on the floor border (1).

According to the gist of the present invention, the spacer (4) does not necessarily have to be interposed.
