Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the structure of a device for connecting a cross beam to a cross-section hollow column for supporting a wall panel that partitions a room or a cross-section hollow column for display purposes. be.

[Conventional technology]

As a prior art for connecting a cross beam with a U-shaped cross section to this type of support, for example, Utility Model Application No. 57-68664
In the publication, an end face of a cross beam having a U-shaped cross section is inserted into a gap between a clamping piece equipped with a downward claw that fits into a locking groove drilled in a side surface of a hollow support and the side of the support. A configuration is disclosed in which a locking claw protruding downwardly is dropped and engaged.

[Problem that the invention attempts to solve]

With this configuration, if the spacing between the pillars, which are installed at appropriate distances on the left and right, deviates even slightly from the specified length of the cross beams, the cross beams cannot be connected, which is an inconvenience. Since the locking pawl on the end surface protrudes only in one direction, there was a problem in that it was not possible to attach the transverse beam with the cross section of the transverse beam upside down.

Therefore, the present invention attempts to solve the above-mentioned problem by making it possible to support the cross beam even when the connecting body is turned upside down when the column and the cross beam are removably connected via the connecting body. It is something.

[Means for solving problems]

Therefore, in the present invention, the connecting body is constituted by a support part that supports the end of the horizontal dyeing, and a pair of left and right engaging claws protruding from the base of the support part, and the pair of engaging claws , the support part is formed in a vertically substantially symmetrical shape so that it can be inserted and locked into a locking groove drilled in the side surface of the support even when both the front and back surfaces of the support part are facing upward; The support part is provided with an upwardly protruding locking claw that engages with a locking hole drilled in the end of the cross beam, and a mounting hole that can be bolted to the cross beam when the support part is turned over. The configuration includes the following.

[Operations and Effects of the Present Invention] According to this configuration of the present invention, the supporting portion of the connecting body is attached to the pillar when the pair of left and right engaging claws of the connecting body are inserted and locked into the locking grooves on the side surface of the pillar. Therefore, even if the length of the cross beam is slightly shorter than the distance between the side surfaces of the support column, the end of the cross beam can be supported by the support part of the connecting body.

A locking hole is drilled at the end of the cross beam, and a locking pawl is provided upwardly on the surface of the support portion to fit into the locking hole, so when the two are fitted together, no bolts are used for the cross beam. It can be installed with.

Moreover, since the engaging claws protruding from the base of the support part of the connecting body are formed in a vertically approximately symmetrical shape, the cross beam can be supported on the support part even when both the front and back sides of the support part are facing upward. Because I can,
When this support part is attached to a support post in an upside-down state, the retaining claws on the support part will face downward.
Therefore, even if the length of the cross beam is shorter than the distance between the sides of the columns, as long as the length of the cross beam is long enough to be placed on the support part of the connecting body, the cross beam attached to the support part can be attached to the support part as described above. This means that it can be supported without being hindered by the retaining claw. In that case, it is sufficient to bolt the cross beam and the support part through the mounting holes provided in the support part.

As described above, according to the present invention, it is possible to connect the supporting part of the connecting body to the cross beam even if it is upside down, and it can also be applied to cases where the length of the cross beam is different, so many types of connecting bodies can be prepared. The effect is that it is not necessary.

〔Example〕

Next, to explain the embodiment, the pillars 1, 1 that support the left and right ends of the wall panels 2, 2 that partition the room are formed with a hollow rectangular cross section, etc., and the pillars 1, 1, which support the left and right ends of the wall panels 2, 2 that partition the room, are formed in a hollow rectangular shape, etc. A pair of left and right locking slots 3, 3 are protruded apart from each other.

A cross beam 4 connected to the pair of left and right columns 1, 1
has a U-shaped cross section, and a pair of left and right locking holes 5, 5 are bored at both left and right ends of the horizontal plate portion.

Reference numeral 6 denotes a connecting body that connects the column 1 and the cross beam 4, and the connecting body 6 includes a support part 7 that is U-shaped in side view and a pair of left and right engagement parts that integrally protrude from the base of the support part 7. As shown in FIGS. 1 and 2, both the engaging claws 8, 8 have a vertically substantially symmetrical shape extending in both the up and down directions. It is constructed so that it can be fitted into and locked into the locking slots 3, 3 in the support column 1.

On one horizontal plate 7a of the support part 7 having a U-shaped cross section in the connecting body 6, left and right retaining claws 9, 9 are provided upwardly projecting. The locking holes 5, 5 can fit therein. Also,
The other horizontal plate 7b in the support section 7 is disposed below the one horizontal plate 7a at an appropriate distance and approximately parallel to the other horizontal plate 7b. ) or a round bolt mounting hole 10 is bored.

With this configuration, when connecting the cross beam 4, which has a pair of locking holes 5, 5 at its ends, to a support column, as shown in FIG. The engaging claws 8, 8 at the base
into the locking slots 3, 3 of the strut 1, and then
The locking holes 5, 5 of the cross beam 4 may be fitted into the respective locking claws 9, 9 of the connecting body 6.

At this time, if the U-shaped cross section of the cross beam 4 is directed downward, the support part 7 of the connecting body 6 can be almost completely covered by both left and right sides and the horizontal part of the cross beam 4, and the cross beam in the connected state can be 4 will not wobble.

Furthermore, as shown in the lower part of FIG. 2, the connecting body 6 can be mounted upside down on the support. That is, by inserting the engaging pawls 8, 8 of the connecting body 6 into the locking slots 3, 3 of the support column 1 with the retaining pawls 9, 9 of the connecting body 6 facing downward, the other side of the supporting part 7 can be inserted. The horizontal plate 7b is in the upper position, and it can be supported even if it does not have the locking holes 5, 5 or is supported by the cross beam 4.

In order to strengthen the attachment strength of the cross beam 4 to the connecting body 6, holes provided in the horizontal part of the cross beam 4 and the connecting body 6
It may be tightened with a bolt 11 that fits into the mounting hole 10 in the horizontal plate 7b. At this time, if the mounting hole 10 is formed in the shape of a long slot, the cross beam 4 can be mounted even if the length of the cross beam 4 is shorter than the distance between the left and right supports 1, 1.

The support portion 7 of the connecting body 6 is not only U-shaped in side view, but can also be formed into a simple horizontal plate shape, and a pair of retaining claws are provided protruding from both left and right sides of the horizontal plate portion. It is sufficient to drill a mounting hole in the middle of the part.
