されることがある。2. Description of the Related Art In erection of a laminated structure such as a steel structure parking lot, for example, when 300 PC slabs are used for each floor, the PC slabs are lifted up one by one and installed. As a result, the higher the height, the longer the lifting time and the poorer the efficiency. Therefore, in order to increase the efficiency of hanging, two PC floor slabs may be mounted by being lifted.

りやすく、危険が伴う。However, in the conventional hanging method as described above, since the two PC floor slabs 3 and 4 hung together are oriented in the same direction, the two PC floor slabs are hung between the beams close to the columns. When installing the lower PC floor slab 4, the upper PC
There is a risk that the floor slab 3 will interfere with the pillars and beams. In addition, when the lower PC floor slab 4 is attached, the upper P directly above the worker.
Since the C floor slab 3 is located, it is necessary to pay attention to the upper PC floor slab 3 during the installation work, and especially the vertical work is likely to occur, which is dangerous.

In the method of hanging with sling wires at the same time, 2
It is characterized in that the PC plates are hung in a state of being opposed to each other so that the longitudinal directions of the PC plates are orthogonal to each other.

けることができる。At this time, the sling wires for suspending the upper PC floor slab and the lower PC floor slab are separated from each other, and an interval between the wires is provided in the middle of the sling wire for suspending the lower PC floor slab. It is advisable to set a wide gap between the wire and the side end face of the upper PC floor slab by interposing a spacer frame for holding the wire. Further, by setting the interval between the upper and lower PC floors to be higher than the floor height, it is possible to avoid interference with the beams on the upper floor.

First, the structure will be described. As shown in FIG. 1, eight sling wires 1 and 2 extend from a predetermined point A connected to a hook of a crane or the like, and four slant wires 1 and 4 (hereinafter, upper sling wire) 1) is used for suspending the upper PC floor slab 3, and the other 4 (hereinafter, lower sling wire 2)
Is used for hanging the lower PC floor slab 4.

より、上階の梁とPC床版との干渉を防止している。The above-mentioned four lower sling wires 2 are longer than the upper sling wire 1 and are fixed to a rectangular frame body 5 serving as a spacer frame in the middle thereof. It is held so that the lateral gap is wide. Also, change the length of the wire 2 to P
By setting the interval between the C floor slabs to be higher than the floor height, interference between the upper floor beams and the PC floor slabs is prevented.

もつ。As shown in FIG. 2, the frame body 5 is a frame in the lower sling wire 2 when the lower PC floor slab 4 is suspended, as compared with the case where the frame body 5 is not interposed. By increasing the inclination angle from the lower PC floor slab 4 between the body 5 and the lower PC floor slab 3, the wire 2 and the upper PC floor slab 3 can be suspended when suspended. It has a role of widening the interval S.

端部を、下側のPC床版4の四隅にそれぞれ取り付けて
該下側のPC床版4も吊り上げる。Then, the lower end portions of the four upper sling wires 1 are attached to the four corners of the upper PC floor slab 3, respectively, and the upper PC floor slab 3 is lifted, and then the lower PC floor slab 4 is mounted. In a state in which the longitudinal direction is relatively orthogonal to the upper PC floor slab 3, the lower end portions of the lower sling wires 2 are attached to the four corners of the lower PC floor slab 4, respectively. The lower PC floor slab 4 is also lifted.

4を同時に吊り込み、目的の階まで揚重したのち、下側
のPC床版4から梁7間に取り付けていく。At this time, since the interval S between the lower sling wire 2 and the upper PC floor slab 3 is set wide by the frame 5, even if the upper PC floor slab 3 swings in the width direction, P
The side end surface of the C floor slab 3 is prevented from interfering with the lower sling wire 2. 2 PC floor slabs, as described above
4 are hung up at the same time, hoisted to the target floor, and then attached between the lower PC floor slab 4 and the beam 7.
【0015】このとき、図4に示すように、下側のPC

る。At this time, as shown in FIG. 4, the lower PC
Since the upper PC floor slab 3 is located between the pillars 6 when the floor slab 4 is attached, interference with the pillars 6 is avoided. Also,
As shown in FIG. 3, since the upper PC floor slab 3 is not directly above the worker B who is installing the lower PC floor slab 4, the PC floor suspended directly above the conventional PC floor slab 3 is not present. The need to work on the plate with care is reduced, and vertical work is safe.
