[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for connecting a column and a crosspiece when forming a partition wall.

[0002]

2. Description of the Related Art Conventionally, a connecting structure for connecting a column and a horizontal rail in forming a partition wall for partitioning a room is known, for example, in Japanese Utility Model Laid-Open No. 55-24420, and the structure is L-shaped. The horizontal piece of the connecting member bent in the shape of a screw is screwed to the horizontal rail, and the vertical piece is inserted into an engagement hole formed in the mounting surface of the support.

[0003]

However, according to the above-mentioned conventional construction, the connecting work includes the work of screwing the connecting member to the horizontal rail, so that the connecting work is not only troublesome but also troublesome. It is also inconvenient when exchanging horizontal rails having different lengths, and since the vertical piece is simply inserted into the engaging hole provided in the column, there is a defect that play is likely to occur between the connecting member and the column. .

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional deficiencies, the present invention provides a support having a pair of front and rear engagement holes extending vertically in a mounting surface, and bending the support into an L-shaped cross section. The vertical piece can be inserted into the engaging hole at the front and rear positions near the bent portion of the vertical piece, and can be inserted into the engaging hole at the tip of the neck that engages with the engaging hole. Vertical engaging tongues each integrally having a head for holding the mounting surface of the column with the back surface of the pillar are provided, and one of the locking projection and the locking hole is provided on the horizontal piece. The connecting member and the horizontal piece of the connecting member are fitted, and the other one of the locking hole or the locking protrusion engaging the one of the locking protrusion or the locking hole on the upper surface of the end. And a horizontal cross-section having a U-shaped cross section with a downward section, and the head of the engaging tongue piece is attached to the back surface of the vertical piece, and It extends vertically from the upper and lower edges of the neck so that there is a corresponding gap, and is formed from an inner edge formed with a long upper portion and an outer edge curved in an arc shape and formed with a tapered upper end. It is intended to provide a connecting structure between the strut and the crosspiece.

[0005]

In operation, when the connecting tongue is inserted from the upper end of the head into the engaging hole of the support while the connecting member is inclined and opposed to the mounting surface of the support, the connecting member is vertically moved. Rotate and push down. Then, the head is immersed in the column, the vertical piece overlaps with the mounting surface of the column, and the mounting surface is sandwiched between the vertical piece and the inner edge of the head of the engaging tongue, and the neck is inserted into the engaging hole. Engage. After attaching the connecting members to the struts facing left and right in this manner, the horizontal rail is pushed down from above so that the horizontal pieces of the connecting members intervene in the ends thereof, and the locking projections are engaged with the locking holes. Is to be engaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described in detail with reference to the drawings. FIG. 5 shows a structure in which a rectangular cylindrical upper frame member 1 fixed to a ceiling and a rectangular cylindrical lower frame member 2 fixed to a floor surface. Square tubular support 3
..., and a horizontal rail 5 is attached between adjacent columns 3, 3 via a connecting member 4 to form a frame body 6, and a partition wall A is formed by fastening panels 7 to front and rear surfaces thereof. Indicates that
A pair of front and rear slit-shaped engagement holes 8 extending in the vertical direction are provided side by side on the mounting surface 3a of the column 3 on which the horizontal rail 5 is mounted.

As shown in FIGS. 3 and 4, the connecting member 4 is formed by bending a plate material into an L-shaped cross section, and extending vertically in the rear direction at positions before and after the bent portion of the vertical piece 9. Locking tongues 10, 10 are provided to engage with the engaging holes 8, 8 provided in the column 3, respectively. The engagement tongue 10 has a neck 11 fitted into the engagement hole 8, and an inner edge 12 a having vertical pieces 9 extending from upper and lower edges of the neck 11.
A vertically extending vertically upward and downward, leaving a gap t corresponding to the thickness of the mounting surface 3a of the support 3 between the rear surface of the support 3 and a long upper portion, and the outer edge 12b is formed in an arc shape. And a head 12 whose upper end is tapered. The horizontal piece 13 of the plate material bent in an L-shape has a locking protruding piece 1 that rises by being cut and raised at the center thereof.
4 is provided, and a reinforcing groove 15 extending in a U-shape along the peripheral edge is provided on the surface portion. 16 are provided respectively.

The horizontal rail 5 connected to the column 3 at right angles by the connecting member 4 is made of a square member formed in a downward U-shape so that the horizontal piece 13 can be fitted therein. Locking holes 17 for locking with the locking projections 14 of the member 4 are respectively formed.

In use, a pair of front and rear engaging tongues 10 of the connecting member 4 are opposed to a pair of front and rear engaging holes 8 and 8 provided on the mounting surface 3a of the column 3, and the imaginary portion of FIG. When the connecting member 4 is inclined as shown by the line, the head 12
From the tapered upper end into the engagement holes 8, 8,
Rotate vertically and push down. Then, the head 12 is immersed in the column 3, and the inner edge 12a thereof is on the inner surface of the mounting surface 3a.
The vertical pieces 9 abut against the outer surfaces of the mounting surfaces 3a, respectively, so that the mounting surface 3a is sandwiched between the head 12 and the vertical pieces 9, and the neck 11 is fitted into the engagement holes 8. After the connecting members 4 are attached to the columns 3 and 3 facing each other in this manner, the horizontal piece 13 of the connecting member 4 is pushed down from above to intervene in the horizontal beam 5. The horizontal pieces 13 are fitted into the ends, and the locking projections 14 provided on the horizontal pieces 13 are respectively inserted into the locking holes 17 provided on the upper surface 5a of the horizontal rail 5, and as shown in FIG. The horizontal rail 5 is connected between the struts 3 facing each other at the position.

[0010]

As described above, according to the present invention, when connecting the support and the crosspiece with the connecting member, the fixing work with screws and the like can be omitted, and the connecting work is extremely convenient.
It has the advantages that the horizontal rail can be easily replaced, the operation of inserting the engaging tongue into the engaging hole is easy, and the connecting member can be attached to the column without play.
