The gap between the upper plate 10 and the lower plate 20 is narrowed when the gap between the upper plate 10 and the lower plate 20 is narrowed by tightening the nut 51 at the bottom of the bolt 50 fastened between the spacers 30 2. Bolts fastened between the upper plate 10 and the lower plate 20 because they are not narrowed above the height of the dog pipe plus the height of the support pipe 40 (which corresponds to the height of the beam 100 to be lifted). Since the tightness of the nut 51 to 50) may be limited, the maximum binding force of the beam 100 may be limited, resulting in excessive pressure during the binding process of the beam 100. It is possible to prevent damage to the beam 100 itself.

However, in the beam 100 binding process, the binding force of the beam 100 is limited by the support pipe 40, but when the washer 31 provided in the spacer 30 is added or removed, the upper plate 10 and the lower plate 20 Since the interval between the) is changed by the height of the plus or minus the washer 31, it is possible to finely adjust the binding force of the beam (100).

Next, the rope 70 which extends from the crane 60 to the protrusion piece 11 of the upper plate 10 is bound, and the beam 100 is lifted by the crane 60.

Since the rope inserting opening 11a is formed in the protruding piece 11 provided on the upper plate 10 of the present invention, the tip of the rope 70 leading from the crane 60 is inserted into the rope inserting opening 11a as shown in FIG. 4. When the crane 60 is operated after the binding, the lifting of the beam 100 can be simply performed.

At this time, in the above description was described as binding by inserting the rope 70 leading from the crane 60 to the rope insertion hole (11a) formed in the protruding piece (11) of the upper plate 10, the ring at the tip of the rope 70 When provided, you may hang the rope insertion hole 11a ring formed in the protrusion piece 11 of the upper plate 10.

As described above, the beam lifting jig A of the prefabricated tent structure according to the present invention includes a body 10 ′ of the upper plate 10 by fastening a bolt 50 passing through the upper plate 10 and the lower plate 20. Since the entire bottom surface is in close contact with the upper surface of the beam 100, and the entire upper surface of the body 20 ′ of the lower plate 20 is in close contact with the bottom surface of the beam 100, the beam 100 may be tightly coupled to the beam 100. It is possible to prevent the flow of the beam 100 in the binding state during the lifting operation, the support pipe 40 in contact with the spacer 30 is positioned between the upper plate 10 and the lower plate 20 to support the support pipe 40 Since the binding force of the beam 100 can be limited, the damage of the beam 100 due to excessive binding in the beam 100 lifting operation can be prevented.

Since the present invention as described above is not limited to the above-described embodiments, it can be changed within the scope not departing from the gist of the present invention claimed in the claims, such changes are within the claims described.
