Of these, the bottom portion 22 is formed in a stepped shape. More specifically, the bottom portion 22 includes a central lower step portion 23 (abutting or close to the floor surface or ceiling surface), two middle step portions 24 on both sides of the lower step portion 23, and each middle step portion 24 and each side. It is composed of two upper step portions 25 (abutting or close to the lower end surface or the upper end surface of the wall material) between the edge portion 21 and the edge portion 21 .

In the present embodiment, the back surface of the lower step portion 23 (the lower surface in FIG. 2) is configured to be flush with the edge 27 of the side edge portion 21 on the lower step portion 23 side. The rail 2 is oriented such that the edges 27 of the lower part 23 and the side edges 21 are on the installation surface side (when fixed to the floor surface, as shown in FIG. It is fixed so that the portion 25 is the uppermost step). Therefore, the lower step portion 23, together with the edge 27 on the lower step portion 23 side of the side edge portion 21, abuts against the installation surface (floor surface or ceiling surface). 23 and the installation surface).

A gap having a predetermined height is formed between each intermediate step portion 24 and the installation surface. In addition, the height dimension of the upper stage portion 25 (the dimension from the installation surface to the upper surface of the upper stage portion 25) is equal to or greater than the height of the bracket 1 (the same dimension as the height of the bracket 1 or greater than the height of the bracket 1). dimensions).

A screw hole 26 for inserting a screw is formed near the end of the intermediate step 24 (the end in the longitudinal direction of the rail 2). A screw hole (not shown) is also formed in the central portion of the lower step portion 23 (central portion in the longitudinal direction of the rail 2).

FIG. 3 is a perspective view of the connecting member 3. FIG. The connecting member 3 is composed of a proximal end portion 31 and a distal end portion 32 . The base end portion 31 has a shape that corresponds to the shape of the recessed portion 15 of the bracket 1 shown in FIG.

It should be noted that the tip portion 32 can also be shaped so that it can be attached to a position between the left and right intermediate step portions 24 .

A screw hole 33 is formed in the base end portion 31 of the connecting member 3 . This screw hole 33 is formed at a position overlapping the prepared hole 16 of the bracket 1 when the connecting member 3 is mounted at a proper position within the recess 15 of the bracket 1, as shown in FIG. 4(1). . Therefore, by inserting a screw (not shown) into the screw hole 33 and the pilot hole 16 from below and driving the tip of the screw into the bracket 1 , the connecting member 3 can be firmly fixed to the bracket 1 .

Further, as shown in FIG. 3, screw holes 34 are formed in the tip portions 32 of the connecting members 3, respectively. These screw holes 34, as shown in FIG. 4(2), are screw holes formed at the ends of the rail 2 when the connecting member 3 is mounted at appropriate positions on both sides of the lower portion 23 of the rail 2. They are formed at positions overlapping with the holes 26 respectively. Therefore, the connecting member 3 is fixed to the rail 2 by inserting a screw (not shown) into the screw hole 26 of the rail 2 and the screw hole 34 of the connecting member 3 from above, and driving the tip of the screw into the floor material. and they can be fixed firmly against the flooring.

FIG. 5 is a perspective view of the bracket cover 4 (4A, 4B). The bracket cover 4A is formed by forming a plurality of screw holes 41 in the upper and lower halves of each surface of a metal plate bent into an L shape, and the bracket cover 4B is flat. A plurality of screw holes 41 are formed in the upper half and lower half of a metal plate.

FIG. 6 is a horizontal sectional view of the vicinity of the side edge 54 of the wall member 5. As shown in FIG. The wall material 5 is constructed by attaching wooden boards 52 (MDF, plywood, decorative plywood, natural wood board, etc.) to both sides of a base material 51 such as polystyrene foam (EPS, XPS). Further, grooves 53 extending from the upper end to the lower end are formed in the side end portions 54 of the wall material 5 at intermediate positions in the thickness direction. The thickness dimension of the upper edge and the lower edge of the wall material 5 (and the portion between them) is slightly larger than the interval dimension between the two side edges 21 (see FIG. 2) of the rail 2. set to small dimensions.

Therefore, when the pair of upper and lower rails 2 are fixed at appropriate positions on the floor surface and the ceiling surface, respectively, the upper and lower edges of the wall material 5 are aligned with the two side edges 21 of each rail 2. You can enter each space in between. When the lower edge of the wall member 5 is inserted into the space between the side edges 21 of the rail 2 fixed on the floor surface, the wall member 5 will be as shown in FIG. A space S is formed between the lower surface of the wall material 5 and the lower and middle steps 23 and 24 of the rail 2 . This space S can be used as a wiring space for power cords, signal cables, and the like.

FIG. 7 is a horizontal sectional view of the column material 6. FIG. Similarly to the grooves 53 (see FIG. 6) formed in the side ends 54 of the wall member 5, the side surfaces of the column member 6 also have grooves extending from the upper end to the lower end at the intermediate position in the width direction (thickness direction). An existing groove 61 is formed. In the example of FIG. 7, the grooves 61 are formed on two adjacent side surfaces, but are formed on two non-adjacent side surfaces (one side surface and the opposite side surface), one side surface, three side surfaces, or four side surfaces. It can also be formed on one side.

The shape and dimensions of the upper end surface, the lower end surface, and the horizontal cross section of the column member 6 are 70 mm square, like the planar shape and dimensions of the bracket 1 . Therefore, the column member 6 can be joined to the bracket 1 so that the four side surfaces of the column member 6 are flush with the four side surfaces of the bracket 1 (see FIGS. 1 and 7).

By using the partition wall unit according to the present invention, partition walls of various shapes can be easily formed. For example, when trying to form a crank-shaped partition wall including two corners C1 and C2 at the position indicated by the dashed line in FIG. The brackets 1 shown in FIG. 1 are arranged at positions C2, and the position of the straight portion L1 between the corner C1 and the existing wall portion W1 and the straight portion L2 between the corners C1 and C2 are determined. The rail 2 shown in FIG. 2 is arranged at the position and the position of the straight portion L3 between the corner portion C2 and the existing wall portion W2.

As shown in FIG. 9, two connecting members 3 are attached to the bracket 1 in advance so as to protrude in different directions by 90°, and are fixed with screws. The bracket 1 is fixed to the floor surface by driving the screws through the screw holes 11 (see FIG. 1(2)) of the bracket 1 into the floor material. Likewise, at the corner C2, the bracket 1 with the two connecting members 3 fixed is arranged and fixed on the floor surface with screws.

Then, the rail 2 is arranged at the position of the broken line shown in FIG. 9, the connecting member 3 protruding from the bracket 1 is connected to the end of the rail 2, and screws are passed through the screw holes 26 and 34 that overlap vertically. are driven into the floor material, and screws are also driven through screw holes (not shown) in the center of the rail 2 to fix the rail 2 on the floor surface.

Also, for the ceiling surface, the bracket 1 and the rail 2 are attached to the floor surface corresponding to each bracket 1 and each rail 2 (directly above) using connecting members 3 and screws. (However, the top and bottom are opposite to the bracket 1 and rail 2 on the floor shown in FIG. 9). These mounting operations may be performed first on the ceiling surface and then on the floor surface, or they may be performed in parallel.

Next, wall materials 5 (see FIG. 6) are placed at respective positions of straight portions L1, L2, and L3 shown in FIG. 8 (between a pair of upper and lower rails 2 fixed to the floor surface and ceiling surface) . The wall material 5 has a height dimension suitable for the space dimension between the upper and lower rails 2 (more specifically, a height dimension smaller than the space dimension between the upper parts 25 of the rails 2 (see FIG. 2), and dimension larger than the distance between the edges 21).

The wall member 5 shown in FIG. 8 (between the existing wall portion W1 and the corner portion C1) is provided at the end portion of the upper and lower rails 2 on the corner portion C1 side. They can be arranged by aligning the positions of the end portions and inserting them by sliding them from the corner C1 side toward the existing wall portion W1 side (in the direction of the arrow shown in FIG. 8). The bracket 1 is arranged at the position of the corner C1, and the height dimension of the upper stage portion 25 of the rail 2 on which the wall material 5 is supported is equal to or greater than the height of the bracket 1, as described above. Therefore, even if the bracket 1 is present at the corner C1, it does not become an obstacle when trying to arrange the wall material 5 on the straight part L1, and the wall material 5 can be slid and inserted without any problem. be able to.

Similarly, the wall material 5 in the straight portion L3 (between the existing wall portion W2 and the corner portion C2) can be arranged by sliding it from the corner portion C2 side toward the existing wall portion W2 side. . In the linear portion L2 (between the two adjacent corners C1 and C2), the wall material 5 is slidably inserted from the corner C1 side toward the corner portion C2 side or in the opposite direction. can be placed.

Then, pillar members 6 (see FIG. 7) are arranged at respective positions of the corners C1 and C2 shown in FIG. In addition, the pillars 6 are manufactured or adjusted so as to have a dimension equal to (or slightly smaller than) the interval dimension between the upper and lower brackets 1 .

After arranging the pillar 6, the bracket cover 4 as shown in FIG. 5 is attached to fix the pillar 6 to the bracket 1. For example, as shown in FIG. 10, the side surfaces of the bracket 1 fixed on the floor (the two side surfaces to which the rail 2 is not connected) and the side surface of the lower end of the pillar material 6 are attached to the outside of the joints. Further, screws (not shown) are inserted into the screw holes 41 on the bracket 1 side (lower side in FIG. 10) and the lower holes 14 on the side surface of the bracket 1, In addition, screws are driven into the column member 6 from the screw holes 41 on the column member 6 side (upper side in FIG. 10) to connect the column member 6 and the bracket 1 .

The bracket cover 4 is similarly attached to the bracket 1 fixed to the ceiling surface and the upper end of the pillar 6 to fix the pillar 6 to the bracket 1 . In the example of FIG. 10, an L-shaped bracket cover 4A is used to fix the pillar 6, but depending on the situation, a flat plate-shaped bracket cover 4B as shown in FIG. 5(2) may be used. can also be used.

Between the pillar material 6 and the wall material 5, as shown in FIG. 11, the nut 7 is arranged using the grooves 53 and 61 (inside the grooves 53 and 61). As a result, the column material 6 and the wall material 5 can be reliably joined without a gap. Also, when joining a plurality of wall materials 5 in series (for example, two wall materials 5 are arranged in a straight line portion L1 shown in FIG. ), the adjacent wall materials 5 can be reliably joined without gaps by placing the joints 7 (see FIG. 11) in the grooves 53 (see FIG. 6) of the joints. can be done.

Although FIG. 8 shows an example of forming a crank-shaped partition wall including two corners C1 and C2, the partition wall unit according to the present invention is a partition wall including only one corner. Moreover, even a partition wall having a complicated shape having three or more corners can be easily formed without any problem.

In addition, the partition wall formed by the above method can be easily removed by removing the screws and removing the components in the order opposite to the order described above, and the screw holes can be removed. The interior can be restored to its original state with only a simple repair work of filling it.
