Positioning in the width direction with respect to the horizontal portion 102 is performed while supporting the connection plate 104 by hand, and thus positioning cannot be accurately performed, resulting in an increase in positioning work time and a decrease in work efficiency.

Since the work of supporting the connection plate 104 and the work of temporarily fixing are performed by different workers, the work efficiency is poor.

The present invention is intended to solve the above-mentioned problems, and an operator can support the connecting plate without using hands, and the connecting plate can be accurately positioned in the width direction with respect to the structural material, and the connection can be made. An object of the present invention is to provide a device for connecting a structural material connecting plate, which enables the same operator to perform the plate supporting work and the temporary fixing work.

[0014]

In order to achieve the above object, the present invention has a pair of side frames arranged substantially parallel to each other and a connecting member connecting the lower parts of the pair of side frames to each other in a predetermined direction. A movable main body having a substantially U-shaped vertical cross section is formed, and a pair of rolling elements that roll on the upper surfaces of both sides of the horizontal portion of the structural member are provided in front of the pair of side frames in the moving direction. A pair of contactors that contact the upper surfaces of both sides of the horizontal portion of the structural member at the rear portion of the side frame in the moving direction, and a pair of guide members at opposite portions of the pair of side frames, The frame is provided with a pair of restricting members at positions corresponding to both sides of a gap formed by the horizontal portion and the connecting member, and the insertion force of the connecting plate inserted into the gap is provided in the vicinity of the connecting member. Provided with a conveyance member that prevents the movement of the side frame and moved more than the pair of contacts of the pair of side frames The rear of the direction, provided with a stopper which contacts the edge of the structural member.

Further, an adjusting member is provided between the pair of side frames to adjust the distance between the pair of guide members and the pair of regulating members.

[0016]

According to the present invention, the operator holds the device main body in correspondence with the end face side of the structural material, moves the pair of rolling elements from the end face side of the structural material, and places them on the upper surface of the horizontal portion to support the device main body. When the apparatus main body is pushed in this state, the pair of rolling elements roll on the upper surface of the horizontal portion and move along the longitudinal direction of the structural material.

Further, the pair of contacts also move while sliding on the upper surface of the horizontal portion, and both side edges of the horizontal portion come into contact with the pair of guide members, so that the apparatus main body is positioned in the width direction of the structural member. . Then, the stopper comes into contact with the edge of the structural material to stop the apparatus body.

In this state, the pair of rolling elements and the pair of contacts are in contact with the upper surface of the horizontal portion, and the frictional resistance of the pair of contacts prevents delusion of the main body of the apparatus. It will be in a suspended state.

At this time, when the connecting plate is inserted into the gap formed between the horizontal portion and the connecting member to support the connecting plate on the conveying member and the connecting plate is pushed along the horizontal portion of the structural member. The connecting plate moves with a slight force to prevent the insertion force from decreasing.

Since the stopper is in contact with the edge of the structural member during the insertion of the connecting plate, the device body does not move in the insertion direction even if the insertion force is transmitted to the device body. Further, the pair of regulating members come into contact with the side edge portions of the connection plate, and as a result, the connection plate is positioned in the width direction with respect to the horizontal portion.

Therefore, the operator can temporarily fix the structural material and the connecting plate by tightening the bolts and nuts.

On the other hand, when using structural members and connecting plates having different widths, it is possible to cope with the width variation by adjusting the distance between the pair of guide members and the pair of regulating members by the adjusting member.
