Therefore, it is possible to prevent a step from occurring at the abutting portions of the upper and lower panels.

FIG. 1 is a perspective view showing a part of an embodiment of the partition device of the present invention.
This partitioning device is composed of a plurality of panels 2 laid in a vertical and multistage manner on the front and rear surfaces of a pair of left and right columns 1, 1. FIG. 1 shows only the upper part of the pair of front and rear panels 2 and 2, but FIG. 5C shows the cross-sectional shape of the opposite end portions of the upper and lower panels 2 and 2.

Each column 1 is formed of a square tube such as a steel pipe.
Each panel 2 is formed by fixing a core material 4 having a required thickness, which is excellent in heat insulation and sound insulation, such as a plaster board, to the back surface of a decorative sheet 3 made of a rectangular thin steel plate formed in required vertical and horizontal dimensions. Has been.

  Folded portions 3a are formed on the left and right side edges and the upper edge of each decorative plate 3 by folding back in the U-shape on the back side, and the backs of the folded portions 3a on both sides contacting the support column 1 are A plurality of slit-like locking holes 5 facing in the direction are formed at appropriate intervals in the vertical direction, and fixed to the side surface of the support column 1 by spot welding or screwing as shown in an enlarged view in FIG. Each of the panels 2 is installed on the left and right columns 1 and 1 by locking the locking holes 5 to the upward hooks 6 a projecting from the front and rear of the bracket 6.

As shown in FIG.5 (c), the bending part 3c provided with the downward protrusion piece 3b in the lower end rear part is formed in the lower edge of each decorative board 3 by bending in a crank shape at the back side. .
By engaging the downward projecting piece 3b with the back surface of the folded portion 3a at the upper end of the lower panel 2, the lower end portion of the upper panel 2 moves outward in the front-rear direction from the upper end of the lower panel 2. Is blocked.

  The core material 4 is fixed to the back surface of the decorative board 3 surrounded by the folded portion 3a between the left and right side edges and the upper edge and the bent portion 3c at the lower edge.

  A plurality of long holes 7 that are long in the left-right direction are formed at appropriate intervals in the left-right direction at an intermediate portion in the left-right direction on the back surface of the folded portion 3 a at the upper edge of the decorative plate 3. An interval holding member 8 for holding the interval W between the panels 2 and 2 facing each other is fixed, and an auxiliary member 9 is straddled on the interval holding member 8.

  The spacing member 8 is formed of a slightly thick metal press-molded body, and has a width slightly smaller than the panel spacing W and opens upward as shown in FIG. The spacer portion 8a has an upward U-shape when viewed from the side and prevents the inward movement of the two panels 2 and 2, and is connected to the front and rear ends of the spacer portion 8a. By forming hooks that face in opposite directions and engaging the left and right edges of the long holes 7 and 7 that are opposed to the front and rear sides of the panels 2 and 2, the front and rear directions of the panels 2 and 2 are directed outward. Widening blocking portions 8b and 8b that prevent movement are provided.

  As shown by a solid line in FIG. 4, the length of the spacer portion 8 a in the direction parallel to the panels 2 and 2 when the spacing member 8 is installed on the front and rear panels 2 and 2 is the distance W between the panels 2 and 2. The length of the spacer portion 8a in the direction perpendicular to the panels 2 and 2 is substantially the same as or slightly smaller than the interval W between the panels 2 and 2.

  When the spacing member 8 faces in the front-rear direction orthogonal to both panels 2, 2, as shown by the solid line in FIG. 4, the front and rear widening blocking portions 8 b, 8 b are elongated holes in both panels 2, 2. It is preferable that the left and right positions of the opposed long holes 7 and 7 in the front and rear panels 2 and 2 are slightly shifted so as to engage with the opposite left and right edges of the front and rear panels 7 and 7.

The auxiliary member 9 is composed of a slightly thick metal press-molded body, like the spacing member 8, and has hanging pieces 9b and 9b at the front and rear ends of the horizontal piece 9a as shown in FIG. The base of the hook-shaped widening blocking portions 8b and 8b of the spacing member 8 (or both side portions of the spacer portion 8a) is fitted to the center of the lower ends of both hanging pieces 9b and 9b. It consists of what provided the notch 10 made to do.
It is preferable to provide inwardly bent pieces 9c and 9c for reinforcement at the lower ends of the both hanging pieces 9b and 9b, if necessary.

  Next, the attachment procedure of the space | interval holding member 8 and the auxiliary member 9 is demonstrated with reference to FIG. 4 and FIG.

  After a pair of front and rear panels 2 and 2 are installed on the front and rear surfaces of a pair of left and right support columns 1 and 1, a spacing member 8 is indicated by a two-dot chain line in FIG. 4 between the front and rear panels 2 and 2. Are fitted so that their long axes are oriented in the same direction as the panels 2 and 2, and then rotated about 90 degrees around the vertical axis so that the widening blocking portions 8 b and 8 b are connected to the two panels 2 and 2. Engage with the left and right edges of the long holes 7, 7.

  When the diagonal line in the plan view of the spacer portion 8a faces in the direction orthogonal to both the panels 2 and 2, the lateral width of the spacer portion 8a becomes maximum, which may be larger than the interval W between the panels 2 and 2. In that case, the intermediate portion of both panels 2 and 2 may be temporarily elastically bent outward to pass the diagonal portion.

When the spacing member 8 is installed on both the panels 2 and 2, the front and rear panels 2 and 2 are moved inward by the spacer portion 8 a of the spacing member 8 so that the intermediate portion that is most easily bent or deformed is moved inward. Similarly, since the outward movement of the intermediate portion in the front-rear direction is blocked by the widening blocking portions 8b, 8b of the spacing member 8, the bending and warping of both the panels 2, 2 are prevented. Also, dropping from the support columns 1 and 1 is prevented.
Therefore, the intermediate connecting material and the lower connecting material in the conventional partition device can be omitted, and the entire structure of the partition device can be simplified.

  In addition, the spacing member 8 can be easily and inexpensively manufactured by simply pressing a metal plate or the like, and the spacing member 8 is inserted between the panels 2 and 2 and rotated approximately 90 degrees. It is possible to easily and quickly attach both panels 2 and 2 simply by making them.

  Further, by performing an operation reverse to the above, that is, by rotating the interval holding member 8 by 90 degrees in the opposite direction to the above, and then taking it out from between the two panels 2 and 2, the interval holding member 8 Can be easily removed from between both panels 2 and 2.

  Next, as shown in FIG. 5 (a), the auxiliary member 9 is inserted into the notch 10 from the upper portion of the spacing member 8 installed between the front and rear panels 2 and 2, and the hook-like shape of the spacing member 8 is formed. The base portions of the widening preventing portions 8b and 8b are fitted so as to be fitted.

  At this time, as shown in FIG. 5B, the upper part of the auxiliary member 9 protrudes upward from the upper ends of the panels 2 and 2. Further, it is desirable that the lower outer surfaces of the both hanging pieces 9b, 9b of the auxiliary member 9 are in contact with the back surfaces of the front and rear panels 2, 2.

  Next, as shown in FIG. 5 (c), the upper panels 2, 2 are placed on the front and rear panels 2, 2, and the downward protruding pieces 3 b are engaged with the back surface of the folded portion 3 a at the upper end of the lower panel 2. In addition, the back surface of each panel 2 is in contact with the upper outer peripheral surface of the two hanging pieces 9b, 9b in the auxiliary member 9, and the upper edge of the locking hole 5 provided on the back surface on both sides of each panel 2 is The bridge 6 is constructed so as to be locked to the hook 6a of the bracket 6.

  Therefore, the lower end portion of each upper panel 2 is prevented from moving inward in the front-rear direction because the back surface thereof is in contact with the upper outer peripheral surface of the two hanging pieces 9b, 9b in the auxiliary member 9. Since the downward projecting piece 3b is engaged with the back surface of the folded portion 3a at the upper end of the lower panel 2, the upper panel 2 is prevented from moving outward from the upper end of the lower panel 2 in the front-rear direction. It is possible to prevent a step from occurring at the two butted portions.

  The present invention is not limited only to the above-described embodiments, and can be implemented in various modified modes as follows, for example, without departing from the scope of the claims.

(a) In FIG. 1, one spacing member 8 and one auxiliary member 9 are shown. However, when only a pair of panels 2 and 2 are attached to the front and rear surfaces of the columns 1 and 1, When mounting on the upper ends of the uppermost panels 2, 2, the auxiliary member 9 is omitted and only the spacing member 8 is mounted.
Further, depending on the situation, the spacing member 8 and the auxiliary member 9 may be attached to only one of the three long holes 7 provided in the front and rear panels 2 and 2 shown in FIG. , Can be attached to two on both sides, or can be attached to all three.

  (b) In the example shown in the figure, the spacer portion 8a of the spacing member 8 has an upward U-shape in a side view opening upward, but this is a downward U-shape in a side view opening downward. In this case, the upper portion of the spacer portion 8a protrudes above the lower panels 2 and 2 and is fitted between the upper panels 2 and 2 to prevent the upper panels 2 and 2 from moving inwardly. It can also be used as a spacer.

It is a perspective view which shows a part of one Embodiment of the partition apparatus of this invention. It is the A section expansion perspective view of FIG. It is the B section enlarged perspective view of FIG. It is a partially notched top view which shows the attachment part of a space | interval holding member.
