DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting rod-shaped members in a simple assembly type structure.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 12, a plurality of rod-shaped members (for example, support members, beams, etc.) 53 are juxtaposed on each wall 52 of a simple assembling type structure 51, such as a shed. It is constituted by being done.

The connection between the wall portions 52 is performed by connecting the rod members 53 to each other. That is, as shown in FIG.
A protrusion 54 having a predetermined width is provided to project right and left, and a recess 55 is formed at the center thereof.
Are formed with through holes 56, respectively.

Further, the width of each of the concave portions 55 is set to be at least the total thickness of the left and right projecting portions 54. When the simple assembling structure 51 is assembled, for example, as shown in FIG.
After the A-side bar members 53A are arranged in parallel, the protrusion 54B of the bar member 53B constituting the upper wall portion 52B is inserted into the recess 55A of one of the bar members 53A from above.

[0005] Next, as shown in FIG. 14B, both protruding portions 54B of another bar-shaped member 53B constituting the upper wall portion 52B are inserted into recesses 54A, 54A of the adjacent bar-shaped members 53A, 53A. To be inserted.

Next, as shown in FIG. 14 (c), wedges 57 are respectively pushed into the through holes 56 formed in the projecting portions 54A, 54B of the bar members 53A, 53B, so that the two bar members 53A, 53B are pressed. The ends are connected to each other and fixed.

As shown in FIG. 14 (d), another bar-shaped member 53A constituting the side wall portion 52A is further provided side by side, and the bar-shaped member 53A and the concave portion at the end of the bar-shaped member 53A adjacent thereto are provided. 55A, the upper wall portion 52B
Are inserted into both projecting portions of another rod-shaped member (not shown).

Thereafter, the wedge 5 is inserted into the through hole 56 in the same manner as described above.
7 is inserted to perform the connection. In this way, the ends of the rod-shaped members 53 constituting the respective wall portions are sequentially connected and fixed by the wedges 57, and a simple assembling structure 51 as shown in FIG. 12, for example, has been assembled. .

[0009]

However, according to the connecting structure of the ends of the bar-shaped members 53 in the above-mentioned conventional simple assembling type structure, after one of the projecting portions 54 is inserted into the other concave portion 55, the projecting portion is projected. In a through hole 56 formed in the portion 54,
Since it is necessary to push (drive) the wedge 57, the assembling work and the disassembling work are very troublesome, and there has been a problem that the wedge 57 is easily pulled out during and after the assembling work.

Further, since the wedge 57 is a part separate from the rod-shaped member 53, there is a problem that the wedge 57 is easily lost. Therefore, an object of the present invention is to provide a connecting portion structure of a rod-like member in a simple assembling type structure capable of solving the above problem.

[0011]

In order to solve the above-mentioned problems, the connecting portion structure of the bar-like members in the simple assembling type structure of the present invention is constituted by a wall portion in which a plurality of bar-like members are juxtaposed. A connection structure between the rod-shaped members in a simple assembly type structure, wherein a pair of protrusions having a predetermined thickness are provided at ends of the rod-shaped members and formed between the pair of protrusions. The width of the recess is set to be at least the total thickness of the two protrusions, and the tip of the protrusion is swingable between a locking position on the recess side and a non-locking position on the protrusion side. A locking piece is attached.

[0012]

According to the above construction, when connecting the ends of the rod-shaped members constituting the wall portions, after inserting one protruding portion into the other concave portion, the locking piece is moved to the locking position side. The two rod-shaped members can be connected only by swinging.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 to 5, reference numeral 1 denotes a box-shaped simple assembling structure according to the present embodiment (for example, a shed)
For example, each of the side walls 2, the top wall 3, the bottom wall 4, and the rear wall 5 has a structure in which a plurality of rod-shaped members 6 are arranged in parallel.

Then, each of the above wall portions, for example, both side wall portions 2
The upper wall 3 and the side walls 2 and the bottom wall 4 are connected to each other by connecting the ends of the rod members 6 to each other. Here, the connecting portion structure at the end of the rod-shaped member 6 will be described.

That is, as shown in FIGS. 6 and 7,
A connecting metal fitting 7 is fixed to an end of the rod-shaped member 6 by, for example, a fixing bolt 8. The connection metal fitting 7 is
As shown in FIGS. 8 to 10, a pair of plate-shaped protrusions 12 having a predetermined thickness is provided from the left and right sides of the main body 11, and at least the left and right protrusions 1 are provided between the two protrusions 12.
A recess 13 having a width that can be inserted therein, for example, a width that is equal to or slightly wider than the total thickness of the two protrusions 12 is formed.

At the tip of each of the protrusions 12,
An oblong locking piece 22 and a spring washer 23 are mounted by the mounting bolt 21, and a flat washer 24 is inserted between these components.

The locking piece 22 is for preventing the protruding portion 12 of the bar member 6 of the connecting partner inserted into the concave portion 13 from coming off. As shown by an arrow a in FIG. It is swingable between a locking position on the recess 13 and a non-locking position on the protrusion 12.

Therefore, in the above configuration, as shown in FIG. 11, for example, when connecting the rod-shaped member 6A constituting the side wall 2 and the rod-shaped member 6B constituting the upper wall 3,
The bar-shaped members 6A on the side wall portion 2 side are arranged in parallel, and the projections 12 of the bar-shaped members 6B constituting the upper wall portion 3 are inserted into the concave portions 13 of the bar-shaped members 6A arranged side by side. After each of the locking pieces 22 attached to the distal end of the protruding portion 12 are swung 90 degrees toward the concave portion 13, the mounting bolt 2
Tighten 1. Then, the two rod-shaped members 6A and 6B are connected to each other very easily and reliably without using a wedge, that is, without the fear of the wedges falling off, as in the related art. can do.

In this manner, while the bar-shaped members 6 are sequentially arranged side by side, the protruding portions 12 at the ends thereof are inserted into the recesses 13 and the locking pieces 22 are swung so that the two bar-shaped members 6 are connected to each other. By connecting with each other, the box-shaped simple assembling structure 1 can be easily constructed.

When disassembling, the mounting bolt 2
After loosening slightly, the locking piece 22 may be swung to the non-locking position on the protruding portion 12 side. Of course, the width of the locking piece 22 is set so as not to protrude outward from both edges of the protruding portion 12 at the non-locking position.

The width of the concave portion 13 or the protruding position of the protruding portion 12 of the rod-shaped member 6 which is disposed at the end side is changed, and the end portion of the wall portion is changed. It is taken into consideration that no gap is formed in the space.

[0022]

As described above, according to the structure of the present invention, when connecting the ends of the rod-shaped members constituting each wall,
After inserting one protruding portion into the other concave portion, it is possible to connect the two rod-shaped members only by swinging the locking piece toward the locking position, and therefore, a structure using a wedge as in the related art In comparison with the above, it is possible to eliminate the need for a locking component such as a wedge that may fall off, and to connect the rod-shaped members very easily and reliably.
