この発明は大型梁床型枠を用いた建物の構築において、
バルコニー用ＰＣ板を梁床部分の施工と同時に行なうバ
ルコニー用ＰＣ板の施工方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to the construction of buildings using large beam floor forms.
This invention relates to a method of constructing a PC board for a balcony, in which the PC board for a balcony is constructed at the same time as the beam floor part.

良くコンクリート工事を行なうことができる。For example, in the construction of high-rise apartment buildings, etc.,
- A large beam floor made by alternately and continuously forming unidirectional beam part formwork and floor part formwork on a truss-shaped temporary beam supported by multiple jacks, as seen in Publication No. 35551. A construction method using formwork is known, and concrete work can be carried out very efficiently by sequentially moving this large beam floor formwork to the upper floors.

と一体化するものが知られている。Regarding the construction of balconies for these buildings, for example, as seen in Japanese Patent Publication No. 1974-1974, the tips of balconies with drains, drainage channels, etc. are precast, and this is installed on formwork. One that is integrated with cast-in-place concrete is known.
ところで、バルコニーについては片持ちのスラブとして

雑な形状が要求される。By the way, since the balcony is formed as a cantilevered slab and a water slope is required, the top end surface has a slope, and the slab thickness is different between the fixed end and the tip. In addition, there are rises to return water, rises to prevent falling,
Complex shapes are required, such as anchors for sashes, handrail anchors, drainage ditches, etc.
これに対し、バルコニースラブ全体を一枚のＰＣ板とす
ることにより、複雑な形状を有し、多職種入り乱れたバ
ルコニーの作業が、ＰＣ板の設置という単一作業に集約
され、また工場生産により品質の向上が図れる。In contrast, by making the entire balcony slab a single PC board, the balcony work, which has a complex shape and involves a variety of jobs, can be consolidated into a single task of installing the PC board, and factory production is also possible. Quality can be improved.
しかし、一方、一枚のＰＣ板としてバルコニーのスラブ

た支持方法が片持ちであることから、先端の垂れ下がシ
等の問題も生ずる。However, on the other hand, forming the balcony slab as a single PC board increases the weight of the PC board, and since the support method is cantilevered, problems such as sagging of the tip arise.

ることを目的として開発された。Therefore, in this invention, the construction of balconies using such PC boards for balconies is incorporated into the construction of buildings using large beam floor formwork to improve construction efficiency, and the PC boards for balconies, which are heavy, can be reliably constructed. It was developed with the aim of making it possible to construct PC boards for balconies with good precision and reliability.

調節するようにすると良い。In the method for constructing a PC board for a balcony according to the present invention, a plurality of second jacks for height adjustment are installed on the overhanging end of a temporary beam of a large beam floor form supported by a plurality of jacks, and Support the extension of the weir plate of the large beam floor formwork with jacks. The balcony PC board is placed on the extension of the sheath board, and the second jack is used to adjust the height and install it at a predetermined balcony position. In addition, P for balcony
Since the C plate is supported in a cantilevered manner, the tip tends to sag. Therefore, it is a good idea to collect data and adjust it slightly upwards in advance.
