クリート４打設前に埋込まれてろる。Recently, an increasing number of multi-story steel-reinforced concrete structures are being designed with precast exterior walls. The concrete was poured and the formwork was dismantled after the structure reached the specified concrete strength.After positioning, the external wall precast boards were hung and the concrete was poured into the concrete. Several fasteners are attached to the anchor, and after inspection, welding is performed, and the fireproof coating of the fasteners and interlayer sealing of the floor are applied to integrate the anchor.

である〇斜上問題点を列記すると欠配の如くである。1' has to overcome the strength development of concrete 4 and 4', and important checks must be made at each step over a long period of time, from embedding the anchor before concrete placement to closing the installation layer. This has to be done over and over again, and for a long period of time, the safety of the unfinished outer wall is poor.
In terms of the construction period, the start of finishing work is delayed, and the construction is currently being carried out with problems such as being uneconomical in terms of construction. be.

を一昂に解消した点にある。The present invention addresses the above two problems,
The gist of this is that the precast concrete plates for the exterior walls should be mixed with 0 parts of salt to 1 part of the skeleton. Insert the V-anchors for the pre-determined anchors during construction, and suspend the precast concrete plates for the exterior wall by supporting them on the lower floor to the frame reinforcements. By applying a slight reinforcing of reinforcing steel, we were able to avoid the risk of unification in terms of construction, and by fixing the structure as one piece of concrete with a wet joint V-joint, we solved the various problems of the slope. The problem is that it has been resolved.

撤去する。The details of this will be explained below based on the example drawings. Fig. 2 shows in detail the joint part between the outer wall precast concrete plate 28 and the frame beam 29 before concrete is poured in the present invention, and shows the structure shown in the figure. As shown, anchors 30 for fixing are embedded in the outer wall precast concrete plate 28 in advance, and the anchor bolts 32 for fixing the jig 31 are also embedded. 31, a clamp member 31b is fixed to the steel frame 33 in the frame at one end of the turnbuckle 3]a, and the bolt 32 is fixed at the other end.
The outer wall precast concrete plate 28, which is formed by fixing angle members 31c with seven insertion holes, is shaped as shown in the figure by supporting its weight without burdening the frame beam 29 in the manner described below. It is suspended and assembled into a predetermined posture with the attachment of the mounting jig 31 and fine adjustment by operating the turnbuckle 31a.After that, (not shown), the anchor 30 and the frame beam reinforcement 34 11 or more reinforcing bars are installed between them to integrate them, and the used mounting jig 31 is removed.
