Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connection structure of upper columns in a partition panel when changing the height of a low partition that partitions a space of an office or the like.
[0002]
[Prior art]
In the case of forming a low partition by hooking opposing surfaces of adjacent panel bodies to each other, etc., when increasing the height of the partition panel, it is necessary to lengthen the column, but conventionally the column itself is It is possible to replace it with a new one with a longer length, or to insert an upper support column having a length that is desired to be increased into the upper end of the existing support column and screw it in.
[0003]
[Problems to be solved by the invention]
As in the former case, if you try to increase the height of the partition panel by replacing the pillars themselves, the panel body and pillars that have already been installed are no longer necessary. Therefore, the work is troublesome, and the construction cost and the cost of the replacement member increase.
[0004]
On the other hand, as in the latter case, connecting the upper strut of the required length by inserting it into the upper end of the existing strut has the advantage that it can be constructed by simply removing the minimum necessary members. If the lower end is simply inserted into the upper end of an existing column and screwed, the strength of the connecting portion is small, and a shelf board or the like cannot be attached to the upper column for use.
[0005]
The present invention has been made to solve the above-described problems, and the upper column is firmly connected to the upper end of the existing column so that the height of the panel can be changed easily and at low cost. It aims at providing the connection structure of the upper support | pillar in the partition panel which did.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the connection structure of the upper columns in the partition panel according to the present invention includes a plurality of vertically elongated holes at least on the front surface side, and each concave groove portion formed on the opposing surface of the panel body adjacent to each other and facing in the vertical direction. A connecting structure for connecting an upper column for attaching a height changing panel to the upper end of the column in a partition panel formed by being attached to a rectangular column-shaped column having
A fitting rod that can be closely fitted in the upper end of the support column protrudes from the inner surface of the upper support column that has a rectangular tube shape that is substantially the same shape as the support column, and the one panel body on one side surface of the upper support column. Reinforcing rods that can be inserted into the concave grooves are fixed in an opposing manner so that a gap slightly larger than the thickness of the side wall of the column is formed between the fitting rod and the fitting rod. When the upper support column is erected by being fitted to the upper end portion, the side wall of the support column is held by the fitting rod and the reinforcing rod.
According to the present invention having the above-described configuration, the upper column is firmly attached to the column by the fitting strength of the fitting rod fitted to the upper end portion of the column and the holding strength of the column side wall by the fitting rod and the reinforcing rod. Since it is connected, the height changing panel can be stably supported.
Further, since it is not necessary to replace the column itself, it is possible to save the trouble of disassembling and removing the existing panel body and re-installing it, and the construction cost and the cost of the replacement member are also reduced.
[0007]
In the connection structure of the upper column in the partition panel according to the present invention, it is preferable that a reinforcing rod capable of holding the other side wall of the column with the fitting rod is provided on the other side surface of the upper column.
If it does in this way, since the both sides | surfaces of a support | pillar are clamped by two reinforcement rods and a fitting rod, an upper support column will be connected more firmly.
[0008]
The connecting structure of the upper column in the partition panel of the present invention is such that bent pieces facing sideways are connected to the front and rear edges of the reinforcing rod, and the front and rear surfaces of both bent pieces are arranged in front and rear in the groove of the panel body. It is preferable to contact or be close to the surface.
In this way, the bending strength in the front-rear direction of the upper column is improved.
[0009]
In the connection structure of the upper column in the partition panel of the present invention, it is preferable to provide a locking member that elastically engages with the vertically long hole of the column when the fitting column is fitted to the column at the lower end of the fitting column. .
If it does in this way, an upper support will not come off easily from a support.
[0010]
The connecting structure of the upper column in the partition panel according to the present invention is such that the locking member is made of an elastic piece that can be bent in the front-rear direction, and is inclined toward the upper front side obliquely at the lower end portion and at the upper end. It is preferable to include an engaging claw portion having a substantially horizontal locking edge that can be locked to the upper end edge of the vertical hole.
In this way, just by fitting the fitting rod of the upper column to the column, the engagement claw portion automatically enters and locks into the vertically long hole of the column and presses the engagement claw portion from the front. If it does, it will detach | leave from a vertically long hole, Therefore The removal of an upper support becomes easy.
