Reference numeral 1 is a connecting device for supporting members for construction according to the present invention, and more specifically, a vertical pillar member 2 that constitutes a pillar structure used in civil engineering and construction sites, and a horizontal joint material and diagonal member connected to the vertical pillar member. , A connecting member 3 such as a cross streak and the like, a supporting member side connecting fitting 4 is attached to the vertical supporting member 2, and a connecting member side connecting fitting 5 is attached to the connecting member 3. .

Therefore, the supporting member side connecting fitting 4 is composed of the supporting member side connecting fitting main body 6 and the supporting member side connecting fitting main body 6.
It is composed of a connecting pin 7 attached to the. The support member side connection fitting main body 6 is a connection plate 6A in which two connection plate units 6A1 and 6A2 projecting outward at desired positions on the side wall of the vertical support member 2 are configured in a U-shape. A hole 6B for a pin opened horizontally at the center of the connecting plate 6A; a connecting pin 7 for the connecting pin 7 to be inserted into the connecting plate 6A by the hole 5B for the pin; An enlarged portion 7B continuously provided to the end portion, a connecting pin slide groove portion 7C having a concave cross-section formed in the side wall of the connecting pin body 7A in the longitudinal direction of the connecting pin body, and the connecting pin slide groove portion. The connecting pin rotating groove portion 7D having a concave cross section formed in the circumferential direction of the connecting pin body in a state of being connected to the outer end of the connecting pin body, and the rod-shaped handle 7E loosely fitted in the circular hole formed in the enlarged portion 7B. It consists of and.

Then, the connecting pin 7 is inserted into the connecting pin sliding groove portion 7C of the connecting pin 7, and the support member side connecting fitting main body 6 is formed.
The connecting pin locking tenon 6D is fitted to the strut member-side coupling fitting body 6. It should be noted that in the illustrated example, the column member side connecting fittings 4 are attached to the upper ends of the vertical column members 2 in four directions, but naturally, the lower ends of the vertical column members 2 are also oriented in four directions. Installed. However, in addition to these four sides, three sides, two sides, or one side may be used.

Further, the connecting member side connecting fitting 5 is provided with a convex connecting plate 5A continuously provided on the end surface of the connecting member 3 in the longitudinal direction of the connecting member 3 and a connection provided at the center of the protruding connecting plate. And a pin hole 5B for use. In the illustrated example, the connecting member side connecting fitting 5 is attached to one end of the connecting member 3, but it is also attached to the other end of the connecting member 3 as a matter of course.

The device of the present invention is used as follows. When connecting the vertical support member 2 and the connecting member 3. In the connecting plate 6A in the supporting member side connecting fitting 4 of the vertical supporting member 2,
The convex connecting plate 5A of the connecting member 3 is inserted, the pin hole 6B and the connecting pin hole 5B are aligned with each other, and the connecting pin 7 is inserted. In this case, as a matter of course, as described above, the connecting pin sliding tenon 6D is provided in the connecting pin sliding groove portion 7C.
To fit. After that, when the connecting pin locking tenon 6D reaches the connecting pin rotating groove portion 7D, the connecting pin 7 is rotated by the handle 7E, so that the connecting pin is securely fixed. Since the handle 7E is loosely fitted in the circular hole formed in the enlarged portion 7B, the handle naturally descends in the direction of gravity (downward) due to its weight. (See FIG. 5) When separating the connecting member 3 from the vertical strut member 2. It is advisable to do the reverse of the above.

[0011]

Since the present invention is constructed as described above, it has the following effects. 1. The combined strength of the pillar structure can be retained. 2. The number of parts has been reduced as much as possible in consideration of assembling, dismantling work, and handling management, so that efficiency can be improved. 3. Since the connecting plate 6A and the connecting pin 7 can be incorporated and integrated into the vertical support member, it is possible to eliminate the need for bolts and nuts as in the conventional case and improve workability during assembly and disassembly. be able to.
