Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a connection structure for connecting a hollow horizontal member to a support column used, for example, in assembling a balcony or verandah.

(Prior Art) Horizontal members often have a hollow part formed in part or the whole so that they can easily withstand loads, and have a shape that is stable in terms of strength. Hereinafter, the horizontal member having this hollow portion will be referred to as a "hollow horizontal member."

Conventionally, when connecting a hollow horizontal member to a column, the following method a or b has been used.

a: Using an L-shaped connecting fitting, screw one side of the fitting to the column and the other side to the hollow horizontal member.

b: A screw pocket is provided inside the hollow horizontal member, and the screw that passes through the pillar is screwed into the screw pocket.

(Problem to be Solved by the Invention) Means a above first screws the other side of the L-shaped connecting fitting to the end of the hollow horizontal member, and then screws the other side of the L-shaped connecting fitting to the end of the hollow horizontal member. This was done by screwing it to the support.

Incidentally, it is preferable that the position for screwing to the hollow horizontal member is set at the center of the width of the hollow portion where the load of the hollow horizontal member is most intensively applied.

However, it is impossible to insert a spanner or a screwdriver into the hollow part of the hollow horizontal member, and the conventional screw tightening position is outside the hollow part.
Therefore, there was a problem that it was difficult to stably receive the load.

On the other hand, when the above-mentioned method b is provided, that is, a screw pocket is provided in the hollow horizontal member, screwing can be performed at a location in the center of the width where the strength is stable. but,
It is not possible to use thick, strong screws for the screws, and a screw that cannot be expected to have much strength is used.Furthermore, the screw pocket cannot be expected to have much strength either, so in this case as well, it is difficult to stabilize the load. There is a problem that it is difficult to accept.

The present invention was developed under the above-mentioned circumstances for the purpose of providing a column connection structure for hollow horizontal members that can stably receive loads.

(Means for Solving the Problems) That is, in the present invention, the hollow horizontal member T having the hollow portion 6 is connected to the support by screwing through the L-shaped connecting fitting J. A column connecting structure of a hollow horizontal member T connected to a column P, in which an L-shaped connecting fitting J connects a tip piece 14 which is clamped and fixed by a screw 1 screwed into the column P so that it can move forward and backward, and a hollow horizontal member T. A base piece 13 is attached to the inner wall of the hollow part 6 of the material T and screwed by a screw 2, and the tip piece 14 is formed with a notch 20 for guiding the screw shaft of the screw 1, and the base piece Piece 1
3 is formed with a screw hole 17 for screwing the screw 2, and the hollow horizontal member T has one of the side walls forming the hollow part 6 at the end on the side where it butts against the column P. By cutting, an insertion opening 12 for inserting a screw operating instrument such as a spanner S is provided, and a screw hole 16 for inserting a screw 2 is provided in the other side wall to which the base piece 13 is attached.

(Function) The hollow horizontal member T according to the present invention is connected to the column P as follows.

On the other hand, the screw 1 screwed onto the support post P is left in a state of protruding outward.

Then, the tip piece 14 of the L-shaped connecting fitting J screwed into the hollow part 6 of the hollow horizontal member T is butted against the connecting surface of the support P (threading surface of the screw 1), and the screw shaft of the screw 1 is along the notch 20 of the tip piece 14, and guide the screw 1 to the screwing position of the tip piece 14, and then insert a screw operating instrument such as a spanner S through the insertion opening 12 to remove the screw operating instrument. Screw the screw 1 into the threaded position of the tip piece 14.

Therefore, in the case of the present invention, in addition to being able to position the base piece 13 within the hollow portion 6 and fasten it with screws, the position of the tip piece 14 can be freely selected. In other words, since the insertion port 12 is formed in the hollow horizontal member T, no matter where the screw 1 is tightened at any position on the tip piece 14 or in the width direction of the hollow horizontal member T. No matter where the screw is located, the screw 1 can be screwed by inserting a screw operating tool through the insertion port 12.
