Japanese Patent Application Laid-Open No. 49806 discloses a device. That is, the overhanging piece of the first member formed into a U-shaped cross section and the overhanging piece of the second member formed into a U-shaped cross section face outward from each other, and the first member and the second member They are arranged so as to be orthogonal to each other. A plate-like body is provided between the first member and the second member orthogonal to each other, and the second member is connected and fixed by the plate-like body so as to maintain a horizontal state with respect to the first member. ing.

A first member is fitted in a first groove of the plate, and a second member is fitted in a second groove of the plate. And the 1st member and the 2nd member are in the state which contact | abutted mutually by the penetration part of the said plate-shaped body. Further, a through hole is formed in the overlapping portion where the first member and the second member overlap each other in a perpendicular state via the through portion of the plate-like body, and a bolt is inserted into this through hole. By screwing a nut to the bolt, the first member and the second member are connected and fixed to each other by a plate-like body.

[0004]

However, the plate-like body is provided between the first member and the second member in a state where the first member is disposed between the first member and the second member.
The member and the second member must be connected and fixed by tightening with a bolt and a nut. Therefore, disposing the plate-like body between the first member and the second member has a problem in that the upper surface of the assembling operation of the frame is turned upside down, and the efficiency of the assembling operation of the frame is poor.

[0005] In particular, 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, a plate-like body is disposed between the first member and the second member. Not only is this troublesome, but when the nut is screwed into the bolt and tightened, it is necessary to prevent the bolt from running idle with a special tool such as a spanner.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to improve the efficiency of assembling work of a frame and to connect a first member and a second member in the frame. An object of the present invention is to provide a frame connecting member capable of facilitating a fixing operation.

[0007]

In order to solve the above problems, the present invention forms a groove on one side 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 in which a second member is fitted so as to intersect the first receiving recess is formed on the same side surface, and the first receiving recess is formed in the main body in which the first receiving recess is formed.
The gist of the present invention is to provide a tightening portion for connecting to a tightening member for connecting and fixing the second member.

[0008]

Accordingly, the main body is disposed from one side with respect to the first and second members that are in the crossed state. Then, the projecting 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 tightened and fixed by connecting the tightening portion of the main body in which the first receiving recess is formed and the tightening member.

Therefore, the first member and the second member can be connected and fixed without interposing a coupling member between the first member and the second member. Further, since the coupling member is engaged with the first member and the second member, the operation for coupling the tightening portion and the tightening member can be easily performed.
