By forming the beams 109 through the columns 107, the beam frames 14A can be quickly and easily formed on the columns 107 at once by simply lifting the beam frame 14A. Moreover, the beam can be installed safely, and the beam can be built at a desired position at a time only by placing concrete on the beam form 14A. In addition, the beam form 14A,
The pillar 1 through the pillar insertion spaces 129A, 129B, 129C
By lifting along 07, the connecting beam formwork 14A hardly moves away from the pillar 107 due to large shaking due to wind or the like, and can be positioned quickly and easily at a predetermined position.
In addition to being able to install a beam form on the pillar 107 in a short time, it is possible to lift the beam safely. Therefore, building 1
Beams 109A and 109B can be efficiently and safely constructed on the column 107 of No. 00.

As described above, according to the present invention, the pier insertion space 29, the column insertion spaces 129A, 129B, and 1 are internally provided.
Connecting hanging tool with formwork 2 in which a column insertion space such as 29C is formed
0, 20A, 20B, 20C and the like, having a connection guide member, the connection guide member, through the column insertion space,
A beam end provided movably in the vertical direction along a pillar member such as a pier 7 or a pillar 107, and a concrete casting space such as a cast-in-place space 16e, 17e, 116e, 117e is formed inside the connection guide member. Connection of abandoned form frames 16, a beam center part abandoned form frame 17, a beam abandoned form frames 116, 117 and the like in such a manner that the concrete placing space and the column insertion space of the connection guide member communicate with each other. I configured it,

By connecting the beam discard formwork of the beam to be constructed to the connecting guide member installed so that the column member is inserted into the column insertion space in accordance with the shape of the beam to be constructed, the beam discarding is performed. The formwork is connected so as to correspond to the shape of the beam to be built by inserting the pillar member, and the connected beam discard formwork only needs to lift the beam on the pillar member to the position to be built. Since it can be installed as a beam form on the pillar member, work at high places such as assembling the form on the pillar member is reduced, and it is easy to ensure the safety of the worker. Or, when building a large number of beams between a number of upright column members, form a desired number of beam formwork at a time without building one beam between these column members. You can In addition, by connecting the beam discard forms by inserting the column members into the column insertion space and lifting the beam members along the column members, the beam discard forms that are connected to each other are greatly shaken by wind or the like. It is possible to quickly and easily position the connected beam discard formwork at the position where the beam should be constructed, as well as to install the formwork for the beam on the column member in a short time. It is possible to lift safely. Therefore, it is possible to quickly and easily and safely install a desired number of beam discard forms forming the form of the beam to be constructed on the pillar member at a time. A beam can be constructed on a pillar member by simply placing concrete on a discard formwork. Therefore, the beam can be efficiently and safely constructed on the pillar member of the building.
