BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame connecting member,
More specifically, the present invention relates to a connecting member for connecting a column of a frame shelf and an auxiliary frame.

[0002]

2. Description of the Related Art A conventional frame connecting structure is disclosed in Japanese Patent Laid-Open No. 2-2.
The one shown in Japanese Patent No. 49806 has been proposed. That is, the overhanging piece of the first member and the overhanging piece of the second member formed in the U-shaped cross section face each other outward, and the first member and the second member are They are arranged so as to be orthogonal to each other. A plate-shaped body is disposed between the first member and the second member which are orthogonal to each other, and the plate-shaped body connects and fixes the second member so as to maintain the horizontal state with respect to the first member. ing.

A first member is fitted in the first groove of the plate body, and a second member is fitted in the second groove of the plate body. The first member and the second member are in contact with each other by the penetrating portion of the plate-shaped body. Further, a through hole is formed in the overlapping portion where the first member and the second member are overlapped with each other in a state of being orthogonal to each other through the through portion of the plate-like body, and the bolt is inserted into the through hole. The first member and the second member are connected and fixed to each other by the plate-shaped body by screwing the nut onto the bolt.

[0004]

However, the plate-shaped body is placed in the state of being disposed between the first member and the second member, and thus the first member is provided.
The member and the second member must be connected and fixed by tightening with a bolt and a nut. Therefore, arranging the plate-shaped body between the first member and the second member causes a problem that the work of assembling the frame body is overturned and the work of assembling the frame body is inefficient.

Particularly, since the work of assembling the frame involves work at a high place, it is desirable that the work has a margin as much as possible. In this case, the plate-like body is arranged between the first member and the second member. Not only is it troublesome, but it is necessary to prevent the bolt from idling with a special tool such as a spanner when screwing the nut onto the bolt for tightening.

The present invention has been made to solve the above problems, and its purpose is to improve the efficiency of the work of assembling the frame body and to connect the first member and the second member in the frame body. Another object of the present invention is to provide a frame connecting member that can facilitate the fixing work.

[0007]

In order to solve the above-mentioned problems, the present invention forms a groove on one side surface of a main body, into which a projecting piece of a first member having a U-shaped cross section can be inserted. Together with forming a first receiving recess into which the first member fits,
Further, a second receiving recess into which the second member is fitted is formed on the same side surface so as to intersect with the first receiving recess, and the main body in which the first receiving recess is formed has the first receiving recess.
Also, the gist of the invention is to provide a tightening portion that is connected to a tightening member that connects and fixes the second member.

[0008]

Therefore, the main body is arranged from one side with respect to the first and second members in the intersecting state. Then, the overhanging piece of the first member is inserted into the groove of the main body, and the first member is fitted into the first receiving recess. Also, the second member fits into the second receiving recess of the main body. Then, the first and second members are fastened and fixed by connecting the fastening member of the main body in which the first receiving recess is formed and the fastening member.

Therefore, it is possible to connect and fix the first member and the second member without interposing a coupling member between the first member and the second member. Further, since the connecting member is engaged with the first member and the second member, the work for connecting the tightening portion and the tightening member can be easily performed.

In FIG. 2, the overhanging piece 5b of the beam 5 juxtaposed on the left strut 2 and the overhanging piece 5b of the beam 5 juxtaposed on the right strut 2 are oriented so that they are directed outward. Each is supported by 2. Further, in the portion where the column 2 and the beam 5 are orthogonal to each other, the plane portion 2a of the column 2 and the plane portion 5a of the beam 5 are in contact with each other. Further, a connecting member 6 is arranged in a portion where the support column 2 and the beam 5 are orthogonal to each other, and the beam 5 is connected and fixed to the support column 2 by the connecting member 6. The pillar 2, the beam 5, the reinforcing frame 3, the lattice 4, and the connecting member 6 constitute a frame body.

Next, the shape of the connecting member 6 and the connecting structure of the column 2 and the beam 5 by the connecting member 6 will be described in detail. As shown in FIGS. 3 to 5, the main body 7 of the coupling member 6 has an octagonal shape. And the main body 7
The first receiving concave portion 8 into which the flat surface portion 5a of the beam 5 is fitted and the groove 9 into which the overhanging piece 5b of the beam 5 is fitted to one side surface.
Are integrally formed. In addition, a second receiving concave portion 10 into which the flat surface portion 2a of the column 2 is fitted is formed on one side surface of the main body 7 so as to be orthogonal to the first receiving concave portion 8.

When the flat surface portion 5a and the projecting piece 5b of the beam 5 are fitted into the first receiving recessed portion 8 and the groove 9 of the main body 7 of the connecting member 6, the flat surface portion 5a of the beam 5 and the second portion. The first concave portion 10 is formed so as to be flush with the receiving concave portion 10.
And second receiving recesses 8 and 10 are formed, respectively. Further, a screw hole 11 as a tightening portion is formed in the main body 7 in which the first receiving concave portion 8 is formed.

On the other hand, the support 2 and the beam 5 are orthogonal to each other, and the flat portion 2a and the beam 5 of the support 2 which are in contact with each other.
Insertion holes 12 and 13 are respectively formed in the flat surface portion 5a, and the insertion holes 12 and 13 are aligned with each other. Then, a bolt 14 as a tightening member is screwed into the screw hole 11 of the coupling member 6 through the insertion hole 12 and the insertion hole 13 of the column 2.

Now, as shown in FIG. 5, the beam 5 is positioned orthogonal to the support 2, and the flat surface 2a of the support 2 and the flat surface 5a of the beam 5 are brought into contact with each other. Further, the insertion hole 12 of the column 2 and the insertion hole 13 of the beam 5 are aligned with each other.

In this state, the side surface of the coupling member 6 on which the first and second receiving recesses 8 and 10 of the main body 7 are formed is opposed to the projecting piece 5b of the beam 5 so that the first receiving recess 8 and the beam. Set 5 and 5 in parallel.

Then, the beam 5 is fitted into the first receiving concave portion 8. Then, the overhanging piece 5b of the beam 5 fits into the groove 9, and the flat surface portion 5a of the beam 5 fits into the first receiving recess 8. Further, the flat surface portion 2a of the support column 2 is fitted into the second receiving concave portion 10 formed so as to be orthogonal to the first receiving concave portion 8. Then, the bolt 14 is screwed into the screw hole 11 through the insertion holes 12 and 13 and tightened, whereby the support column 2 and the beam 5 are connected and fixed by the coupling member 6 and the bolt 14.

Therefore, when the beam 5 is connected and fixed to the support column 2 by the connecting member 6, the connecting member 6 only needs to be fitted into the beam 5 and the support column 2 from the beam 5 side. The work of connecting and fixing 5 can be facilitated.

Further, with the insertion holes 12 and 13 and the screw hole 11 of the coupling member 6 aligned, the bolt 14 is screwed into the screw hole 11.

When the bolt 14 is tightened with a dedicated tool such as a spanner, the first and second receiving recesses 8 and 10 of the coupling member 6 are in the engaging relationship with the support column 2 and the beam 5, so that the coupling member 6 is lightly pressed. For example, the connecting member 6 does not idle. Therefore, the bolt 14 can be easily tightened with a dedicated tool, and the column 2 and the beam 5 can be connected and fixed by the bolt 14 and the connecting member 6.

As a result, when tightening the bolt 14,
A dedicated tool for preventing the coupling member 6 from idling is unnecessary, and the work of assembling the support 2 and the beam 5 can be facilitated.

Further, since the work for assembling the support column 2 and the beam 5 can be spared, the work for assembling the frame body at a high place can be carried out safely. Furthermore, the coupling member 6 having a predetermined size can accurately connect and fix the support column 2 and the beam 5.

In this embodiment, the main body 7 of the connecting member 6 is
The screw hole 11 is formed in the insertion hole 1 as shown in FIG.
Stud bolt 15 as a tightening part for inserting 2 and 13
May be provided. In this case, when the stud bolt 15 is inserted with the insertion holes 12 and 13 aligned, the stud bolt 15 is caught by the beam 5, so that the beam 5 can be temporarily fixed to the column 2.

When the nut 16 as a tightening member is screwed onto the stud bolt 15 and tightened,
The column 2 and the beam 5 can be connected and fixed by the nut 16 and the connecting member 6.

In this embodiment, since the beam 5 is orthogonal to the support column 2, the first receiving concave portion 8 and the second receiving concave portion 10 formed on the connecting member 6 should be orthogonal to each other. However, when the column 2 and the beam 5 are not orthogonal to each other, the first receiving concave portion 8 is formed in the coupling member 6 according to the angle.
It is also possible to form the second receiving recess 10.
