た鉄筋の運搬方法を提供することを目的とする。However, the above-mentioned conventional method of transporting a reinforcing bar has a complicated and inefficient drawback. That is, since a reinforcing bar storage area is determined within a range where floors are to be arranged and the reinforcing steel bars are hoisted and transported little by little to this storage area, this is a very complicated task because of the need for close communication and a large number of repetitions. It is often difficult to secure a rebar storage area depending on the situation of the bar arrangement work. In addition, the rebar transportation distance from the rebar storage area to the rebar location becomes long, which may result in inefficient and troublesome transportation. SUMMARY OF THE INVENTION An object of the present invention is to provide a method of transporting a reinforcing bar for a structure including a reinforced concrete floor and a beam member, by eliminating the lifting and transporting of floor reinforcing bars little by little.

ある。A method of transporting reinforcing bars according to the present invention is a method of transporting reinforcing bars used for the floor of a structure having a floor made of reinforced concrete and beam members arranged above the floor. , The bundle of reinforcing bars is hung in parallel on the lower surface side in the arrangement posture of the beam member, and the beam member is lifted to a predetermined position as it is, and the beam member and the reinforcing bar bundle are arranged after the beam member is arranged. The reinforcing bar bundle is hung down near the floor by a lifting device interposed therebetween.

絡等を必要とせず、床上だけで実施できる。When the beam member is hoisted and arranged at a predetermined position, the bundle of reinforcing bars is also hoisted and conveyed, and is hung in parallel under the beam member. When this bundle of rebars is required, it is hung up to the vicinity of the floor by a lifting device interposed between the beam member and the bundle of rebars, and therefore a rebar storage space is required on the floor for the first time. Further, the operation of the lifting device does not require contact with the ground and can be performed only on the floor.

取り外しやすいし、傷もつかない。1 is a longitudinal sectional view showing an embodiment of a method for carrying a reinforcing bar according to the present invention, and FIG. 2 is a perspective view of a construction to which the method for carrying a reinforcing bar in FIG. 1 is applied. In the figure, 1 is a steel beam as a beam member, 2 is a reinforcing bar, 21 is a reinforcing bar bundle, 22 is a barb wire wire rope for the reinforcing bar bundle 21, 3 is a lifting device, 31 is an upper balling wire for the lifting device 3. Rope, 32 is a lower ball sling wire rope for the lifting device 3, 4 is a floor, and 5 is a reinforcing bar mounting table. The method of transporting the reinforcing bars according to the present embodiment employs a structure in which the steel beams 1 are arranged on a floor made of reinforced concrete, and as shown in FIG. 1, the reinforcing bars 2 are suspended below the steel beams 1.
Specifically, the reinforcing bar bundle 21 bound with a binding steel wire is attached to the lower surface side of the steel beam 1 in the arranging posture, and a sling wire rope 22 is attached.
Plural pieces are suspended in parallel with the steel beam 1. The amount of the reinforcing bar 2 to be hung corresponds to the set range of the floor below the steel beam 1, and the reinforcing bar bundles are coated by applying an identification color to the upper bar, the lower bar, and the bend bar of the floor bar. Summarize in 21. The ball rope wire rope 22 uses the duct sleeve 11 provided in advance on the steel beam 1, and the wire rope protection pad 12 is interposed at the end thereof, and when inserted into this, after use,
Easy to remove and no scratches.

も良い。A lifting device 3 is interposed between the steel beam 1 and the reinforcing bar bundle 21. Therefore, the upper bead wire rope 31 for the lifting device 3 is wound around the steel beam 1 side, and the lower bead wire rope 32 for the lifting device 3 is wound around the rebar bundle 21 side. The upper and lower hooks of the lifting device 3 are locked. As the lifting device 3, a small manual chain block is used, and two sets of this are mounted near the front and rear ends of the reinforcing bar bundle 21. The lifting device 3 is interposed between the reinforcing bar bundle 21 and the steel beam 1. With the hanging process,
Do it on the ground. However, it may be interposed after the steel beam 1 is attached. As described above, the steel beam 1 in which the reinforcing bar bundle 21 is suspended
Is lifted by a crane or the like as in the conventional case, and as shown in FIG.
Therefore, in this case, the steel beams 1 on the second and third floors facing in a certain direction
Each of them is assembled in a state in which a small number of reinforcing bar bundles 21 are suspended. Then, depending on the reinforcement work of the floors on the second and third floors, the reinforcing bars 2 corresponding to the necessary range are directly under the operation of removing the ball sled wire rope 22 and switching to the suspension by the lifting device 3. Reinforcing bar mounting table 5 prepared in advance on the floor 4
Get down. The mounting table 5 is provided on the steel beam 1, but when the beam is provided, the legs of the mounting table may be provided on the beam.

位置への距離が短い。Since the method of transporting the reinforcing bar of the present embodiment is performed in this way, the frequent frequent lifting and transporting of the reinforcing bar as in the conventional case is eliminated, and the required amount of reinforcing bar can be immediately taken out by the operation on the floor. Ready, close connection between the floor and the ground, hoisting work with a crane, etc., which requires cooperation will be significantly reduced, streamlined, and safety will be increased. Furthermore, even on the floor, it is sufficient to prepare a rebar storage area in a short time with a small area, so there is very little effect on the rebar placement work, and the position of this rebar storage area is rational, and the distance from this to the rebar location short.

For example, it is possible to easily and quickly attach / detach the beam member and the reinforcing bar bundle to / from the lifting device by using the upper and lower ball sling wire ropes of the lifting device as dedicated clamp fittings. Further, it is possible to reduce the number of lifting devices to be prepared by mounting the lifting device on the floor with respect to the steel beam placed on the floor and the bundle of suspended reinforcing bars. Further, this lifting device can be other than the chain block, or can be of an electric type,
It is also possible to further facilitate the hanging.
