Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel frame supporting device for supporting both members when temporarily joining a joint member and a column member in a steel frame structure.

[0002]

2. Description of the Related Art Generally, when temporarily joining a joint member and a pillar member in a steel frame structure, both members are supported by a predetermined device.

[0003] Conventionally, this supporting device is provided with a port stand that is fixed to a predetermined position to support a port member, and a column base that supports a column member to be welded to the port member. The mouth stand and the pillar stand are alternately arranged, and after the joining member and the pillar member are placed on each stand, both members are temporarily welded.

[0004]

In the above-mentioned conventional supporting device, since the column bases are arranged between the connection bases, the distance between the bases is small, and the temporary welding of the members in the narrow space is performed. There is a problem that work for is very difficult.

Further, since each stand is fixed at a predetermined position and does not have a mechanism for adjusting the position of each installed member, the length of the pillar member is set to the position installed on the port. If the distance between the mouth members does not match, a gap is created between both members, and the work of temporary welding becomes difficult. Therefore, in this case, there is a problem that a high level welding technique is required.

[0006] Therefore, an object of the present invention is to provide an iron aggregate supporting device capable of solving the above problems.

[0007]

Means for Solving the Problem The means for solving the problems in the present invention is to provide a plurality of sorting carts having a support table for mounting a sorting member so as to be movable along a guide rail. A positioning device for positioning the joint member on the support base, a pillar support base for mounting the end portion of the pillar member to be welded to the joint member, and a pillar member on each carriage. An adjusting device is provided on the pillar support for adjusting the connecting member in a direction perpendicular to the central axis of the connecting member.

[0008]

In the above means for solving the problems, the connection member is placed on the support base of the connection carriage, the support base is positioned by the positioning device on the support base, and the pillar member is mounted on the column support base of the connection carriage. And adjust the pillar member on the pillar support base in the direction perpendicular to the center axis of the joint member by moving the joint carriage along the guide rail to bring the joint trucks closer to each other. Then, the connection member and the column member are brought into contact with each other.

7 and a roller chain 83 wound around.

Although not shown, in order to move the other supporting carriage 9 along the guide rail 5, a moving device 11 having the same structure as described above is provided, or the other supporting carriage 9 has its own moving device. Should be provided.

In the above structure, the position of the support rod 63 in the adjusting device 6 is adjusted in advance according to the welding position of the column member 2 with respect to the joint member 1. For example, the adjusting device 61 may be adjusted so that the axial center of the pillar member 2 coincides with the center of the joint member 1.
After adjusting the position of the support rod 63 in the column, the both ends of the column member 2 are placed so as to be delivered to the column support base 60 of the adjoining truck 6 and the column support 86 of the support truck 9, respectively, and then pressed. The cylinder device 67 is driven to press and fix the column member 2 to the positioning roller 65 side by the pressing roller 70, and the positions of the members 1 and 2 in the width direction, that is, the direction perpendicular to the center of the port member 1 are adjusted. To finish.

Next, when the moving motor 75 is driven in order to bring the pillar member 2 into contact with the side surface of the joint member 1, the traveling sprocket 82 rotates, and accordingly, the moving roller 7 rotates, The movable joint carts 6A and 6B and the support cart 9 move to the fixed joint cart 6C side, the gap between the joint member 1 and the pillar member 2 is filled, and the joint member 1 and the pillar member 2 come into contact with each other. .

In this state, the operator welds the upper part of the contact portion between the joint member 1 and the pillar member 2 from above, or the joint member 1 and the pillar member 2 in the working groove 3. The lower part of the contact part should be welded.

Further, according to the embodiment of the present invention, the column base which is conventionally provided is omitted, and the column member 2 is attached to the connection cart 6.
By providing the column support base 60 for supporting the ends of the column base, a work space for the column base (lower side of the column member 2) can be secured, and therefore, the contact member 1 and the column member 2 are brought into contact with each other. When welding the parts, the welding work can be easily performed, and the burden on the operator can be significantly reduced.

Further, since the movable joint carriages 6A and 6B are provided so as to be movable along the guide rails 5, the movable joint carriage 6 is provided.
By moving A and 6B, the pillar member 2 can be moved in the direction along the guide rail 5, so that the gap between the joint member 1 and the pillar member 2 which has been generated in the past can be eliminated. Therefore, the worker is
2 can be easily provisionally welded without requiring advanced welding technology.

[0033]

As is apparent from the above description, according to the present invention, the mounting carriage for supporting the end member is provided with the mounting table for supporting the end portion of the pillar member. Since the base can be omitted and the portion can be used as a work space, it is easy to perform the welding work of the connection member and the pillar member, and the burden on the operator can be greatly reduced.

Further, since the joint carriage is provided so as to be movable along the guide rail, the joint member and the pillar member can be moved by bringing the joint carriages close to each other after the pillar member is installed on the mounting table of the joint carriage. The members can be brought into contact with each other without a gap, and therefore, the welding work of both members can be easily performed without requiring a high level welding technique.
