構造用外壁を構築するプレキャスト鉄筋コンクリート外
壁用半製品に関する。[Detailed description of the invention] This invention has a thin flat part formed with a wall thickness thinner than the structural outer wall of a building, and the outer surface of the thin flat part is finished, and the inner surface of the thin flat part is finished. In this method, a part of the reinforcing bars protrudes toward the inside of the building, and while the reinforcing bars are kept erected at the site, wall reinforcements are placed inside the reinforcing bars that are integrally connected with the protruding reinforcing bars. The present invention relates to a semi-finished product for precast reinforced concrete exterior walls, which constructs a structural exterior wall with openings by integrally joining it with concrete to be installed.

場作業との合理的な組合わせに基づいて優れた効果を奏
する。When constructing the structural exterior walls of high-rise buildings, this type of semi-finished exterior wall products require a shorter curing period than when constructing the entire exterior wall with cast-in-place concrete and finishing the exterior on-site. By using this semi-finished product, which has been finished in advance, as the outside formwork, it is much more efficient, and the weight of the precast reinforced concrete exterior wall, which has the same thickness as the exterior wall from the beginning, is much higher. Compared to the case of connecting finished products side by side, it is easier to transport and erect on site because it is lightweight, and the connection strength between items placed side by side is high, making it possible to streamline factory production and on-site work. Excellent effects can be achieved based on combinations of
而して従来のこの種の外壁用半製品で窓用開口部を形成

ツシ枠が外壁用半製品とは別体構成され、現場において
そのサツシ枠を取付けていた。However, in conventional semi-finished products for exterior walls of this kind that form window openings, the sash frame to be attached to the inner peripheral part is constructed separately from the semi-finished exterior wall products, and the frame is not assembled at the site. A satsushi frame was installed.
そのためサツシ枠取付は作業に手間を要するといった問

リートが廻り込み難く強度低下をもたらしやすいという
問題が指摘されていた。As a result, there is a problem in that installing the sash frame requires time and effort, and distortion occurs in the area around the window opening, which is the weak point of the semi-finished product. It has been pointed out that there is a problem that warpage is likely to occur, and that only the peripheral portion is thick, making it difficult for poured concrete to go around the underside, resulting in a decrease in strength.

成しであることを特徴とする。The precast reinforced concrete semi-finished product for external walls according to the present invention was developed in view of the above-mentioned circumstances, and has the structure described above, in which a sash frame is embedded and fixed in advance in the inner periphery of the opening, and the sash frame is embedded and fixed in the area around the embedded sash frame. It is characterized in that a portion below the sash frame is thicker than the thin flat portion and has the same or approximately the same thickness as the outer wall.

、ひいては施工精度の向上を達成できるに至った。In other words, since the sash frame is buried and fixed in advance, not only can the conventional on-site installation work be omitted, but the rigidity of the sash frame that has been buried and fixed can be used to strengthen the area around the opening, which is the weak point. By reinforcing the entire semi-finished product, it can be prevented from warping or slightly increased in rigidity.In addition, it is possible to suppress the deformation of the sash frame itself, and it is possible to pour concrete not only in the surrounding area but also in the lower part. By creating an unnecessary thick wall and avoiding a decrease in strength due to insufficient wrapping, we have been able to improve workability as a whole, as well as improve product accuracy and construction accuracy.
