DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments. FIG. 1 illustrates a first embodiment of a member for assembling a temporary structure. Specifically, FIG.
FIG. 2 illustrates main parts of a column member 1 and a beam member 2.

As shown in FIG. 1A, the column member 1 is formed by welding a connecting portion 4 in the middle of a round pipe 3. In the illustrated example, one connecting portion 4 is welded to the center of the round pipe 3 in the longitudinal direction. However, two or more connecting portions 4 may be welded as needed. It is.

The connecting portion 4 is formed in a hollow regular octagonal column as a whole, and has a regular octagonal top portion 5 and a bottom portion 6 having an opening hole in the center, and a bent side portion 7 covering each side surface of the octagonal column. Are integrated with each other. The top 5
An opening formed in the bottom 6 has an inner diameter substantially the same as the outer diameter of the round pipe 3, and the connecting portion 4 and the round pipe 3 are welded in upper and lower opening holes.

The top 5 and the bottom 6 each have a regular octagonal shape with a side of length a. On each side of the regular octagon at the top 5, there are two notched grooves 8 connected to the side 7 respectively. Is formed. Note that the length of the notch groove 8 at the top 5 is L
1. The length of the notch groove 8 in the side part 7 is L2 (see FIG. 2). Further, the width of the notch groove 8 is W.

As shown in FIG. 1B, the beam member 2 is formed by welding a locking member 10 to the inner surface of the tip of a rectangular pipe 9. Note that the horizontal width a of the locking member 10 is
It is substantially the same as one side a of the regular octagon of the connecting member 4. Also, the vertical height b of the square pipe 9 and the locking member 10 is
It is almost the same as the height b of the side part 7 of the connecting member 4.

As shown in FIG. 3, the locking member 10 is formed by integrating a flat main body 11 and two inverted L-shaped hooking pieces 12. In addition, the hook piece 12
The main body 11 is formed so as to protrude from a position that substantially divides the main body 11 into three. Needless to say, the positions of the two hook pieces 12 coincide with the positions of the two notch grooves 8 formed on each side surface of the connecting portion 4.

As shown in FIG. 2, an inverted L-shaped hook portion 1 is provided.
2 is a base end B protruding in the longitudinal direction of the rectangular pipe 9;
An extension E extends downward from the base end B. The shape and dimensions of the hook portion 12 correspond to the notch grooves 8 formed in the connecting portion 4, and the width of the hook portion 12 is
It is formed slightly thinner than the width W of the notch groove 8.

Similarly, the length L1 'of the base end portion B in the projecting direction.
Is formed to have a length substantially equal to the length L1 of the notch groove 8 of the top 5. The length L2 ′ of the base end B in the vertical direction is also set.
Is formed to have substantially the same length as the length L2 of the cutout groove 8 in the side portion 7. In addition, the portion of the length L3 of the extension portion E is a portion that comes into contact with the inner surface of the side portion of the connecting portion 4 to realize the reliable connection between the column member 1 and the beam member 2.

FIG. 4 shows a reinforcing member 20 used to reinforce the connection strength between the column member 1 and the beam member 2. The reinforcing member 20 is formed by forming an extended portion 22 on the distal end side of a hollow rectangular column member 21, and the inner periphery thereof is formed slightly larger than the outer periphery of the rectangular pipe 9.

That is, the horizontal inner diameter a ′ of the reinforcing member 20 is slightly larger than the horizontal width a of the square pipe 9,
The vertical inner diameter b ′ is formed to be slightly longer than the vertical height b of the square pipe 9 and the connecting portion 4. Therefore, the reinforcing member 20 can slide on the outer circumference of the square pipe 9, and when slid in the distal direction, the extending portion 22
Can sandwich the connecting portion 4 from above and below, and the connection between the column member 1 and the beam member 2 can be made more reliable.

FIG. 5 shows an extension member 30 used when the column member 1 is extended in the vertical direction. The extension member 30 is configured by integrating a disk portion 31 having an outer shape substantially equal to the outer shape of the round pipe 3 and a columnar portion 32 penetrating through the disk portion 31 and projecting vertically. Here, the outer diameter φ of the protruding portion 32 is substantially equal to the inner diameter of the round pipe 3, which enables the column members 1 to be reliably connected in the vertical direction.

Subsequently, using the members described above,
A case of constructing a framework including a temporary stage and a scaffold at a construction site will be described. When constructing a framework of a temporary stage or the like, it is necessary to bridge the beam member 2 between the adjacent column members 1 and 1 with some column members 1 standing. In such a case, the inverted L-shaped hooking piece 12 protruding from the beam member 2 may be inserted into the notch groove 8 formed in the connecting member 4 from above. Unlike the conventional case, since the connecting member 3 extends radially outward of the round pipe 3 and furthermore, it is sufficient to drop the hooking piece 12 into the notch groove 8 from above, the assembling work is extremely easy. is there.

Since the connecting member 3 has an octagonal shape in plan view, as shown in FIG. 6, the beam member 2 is assembled to the column member 1 in any of the eight directions. It can be used for any shape of stage or building. In order to increase the assembling strength of the column member 1 and the beam member 2, the reinforcing member 20 is previously inserted into the square pipe 9, and the hook piece 12 of the beam member 2 is inserted.
Is dropped into the notch groove 8 of the connecting member 4, the reinforcing member 20 is slid and the connecting portion 4 is sandwiched by the extending portion 22 from above and below.

When the column member 1 and the beam member 2 are assembled in this manner, and a board material or the like is laid on the horizontal plane formed by the beam member 2, a temporary stage or a construction scaffold can be completed. At this time, the connecting member 4 and the beam member 2
Are flush with each other, the board member can be supported by the connecting member 4 and the beam member 2. When the skeleton is extended in the vertical direction, the column members 1 may be continuously provided using the extension members 30 shown in FIG.
