Description of the Related Art In many racks, for example, when a large number of refrigerant pipes are stacked inside a refrigerant pipe rack, a heat insulating material of a refrigerant pipe located at a lowermost end is compressed by a load of an upper refrigerant pipe, and a condensation accident occurs. May occur. Therefore, in order to prevent such an accident, there is a case where means for increasing the auxiliary girder to partition the inside of the rack into a plurality of stages is adopted. The means for increasing the auxiliary girder is similarly employed in the case of increasing the number of wires and pipes in a metal duct, a large cable rack, and the like outside the refrigerant pipe rack.

As shown in FIG. 0, a mounting hole 11 for additional sub-girder is drilled in the side of the main girder P of the rack, and the auxiliary girder 10 inside the main girder P is connected by connecting bolts inserted into this mounting hole. is there.
To drill the mounting hole 11, a method of drilling a portion positioned at a predetermined height with a drill, or a knock hole is provided in advance on a side surface of the parent girder P of the rack, and if necessary, the knock hole is provided. There is a method of punching out and punching. The connecting bolt 12 is inserted from outside of the mounting hole 11 thus drilled,
The connecting bolt 12 is screwed to the end of the auxiliary spar 10 inserted into the rack, and the additional work is completed. A nut member 13 to be screwed to the connection bolt 12 is provided at an end of the auxiliary girder 10 in advance.

返さなければならない。However, since it is necessary to set a number of auxiliary girders 10 at the same height, positioning work on the side of the main girder P of the rack and drilling work using a drill are required. However, performing such operations on site has the disadvantage of requiring a great deal of labor and work time. Moreover, since the position of the mounting hole 11 once drilled cannot be changed anymore, if the mounting position of the auxiliary girder 10 is further changed, the positioning operation, the drilling operation, etc. are performed again. Must be repeated.

The auxiliary girder 10 can be easily rotated around the connection bolt 12. Therefore, connecting bolt 12
If not very firmly tightened, when laying piping or wiring along the auxiliary girder 10, the attached auxiliary girder 10
Could rotate. If even one of the auxiliary girders 10 rotates, the mounting surface formed by each auxiliary girder 10 will have irregularities, and the corners of the auxiliary girders 10 will hit the side surfaces of the piping and wiring. . Then, the protruding part of the mounting surface exerts an excessive load on the side surface of the pipe or the wiring, and there is a possibility that the side surface is deformed or damaged.

The girder 10 also rotated at the same time, and the work itself of firmly tightening the auxiliary girder 10 for expansion was also a difficult operation.

When this auxiliary girder 10 is used, an auxiliary girder 10 having the same length as the interval of the main girder P is required. For example, a channel material made of lip channel steel is cut off at the site, and It was difficult to use it as a child girder Q for expansion.
