【発明の詳細な説明】
本発明は建造物の基礎梁の伏設に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to laying down foundation beams of buildings.
従来この種基礎を第１図のように布基礎工法に
依る時は、柱間の繋ぎ梁を接地のフーチングと一
体として、その断面は第２図のように割栗上の均
しコンクリート上に現場施工していた。 Conventionally, when this type of foundation was constructed using the cloth foundation method as shown in Figure 1, the connecting beam between the columns was integrated with the grounding footing, and its cross section was laid out on leveled concrete on a chestnut as shown in Figure 2. Construction was being carried out on site.
基礎は地盤と密着することが必要であるから、
この場合としては、割栗地業上に型枠を組んでコ
ンクリートを打設し、更に幅狭部分の型枠を組む
などし、コンクリートの凝固を待つ日数も多くな
つていた。 Because the foundation needs to be in close contact with the ground,
In this case, formwork was set up on the Warikuri land and concrete was poured, and formwork was then set up for the narrower areas, resulting in many days spent waiting for the concrete to solidify.
本発明はこのような工期を短縮し、工費の軽減
を図るため、第４図のように工場生産梁を現場の
フーチング上に据え、モルタル着けし、梁の交叉

る。 In order to shorten the construction period and reduce construction costs, the present invention, as shown in Figure 4, installs factory-produced beams on the footings at the site, applies mortar, and fills the intersections of the beams with concrete. Build the foundation beam.

して取出筋となつていることを示す。 An example will be described. In Figures 4, 6, and 7,
Both ends of the downward curved reinforcing bar 1 with continuous bending lines and both ends of the horizontal reinforcing bar 2 are welded to create an arcuate reinforcing bar, and both ends of the upward curved reinforcing bar 3 with continuous bending lines and both ends of the horizontal reinforcing bar 4 are welded together. Weld them to make arcuate reinforcing bars. Double arcuate reinforcing bars are placed back to back, and steel bands 5 are inserted in parallel between the two, and each contact point is welded.The reinforcing bar beam is covered with a plastic material 6, which is generally made of lightweight concrete. to make a shaped beam. This plastic material 6 not only covers the reinforcing bar beams, but also aims to maintain the rigidity of the reinforcing bar beams and prevent buckling, and the material is preferably lightweight.
Since the strength of the wood size itself is not expected, it can be made of calcareous or earthy material, or even plastic material. In this way, shaped beams can be produced in a factory. FIG. 6 shows that the tips of the horizontal reinforcing bars 2 and 4 extend and protrude to serve as rebars.
成形梁は敷設位置のフーチング上に据付モルタ
ル７により定着され、交点では現場打ちコンクリ
ート８により結合されて基礎梁が構築されたこと
は図示のとおりである。 As shown in the figure, the formed beams were fixed on the footings at the installation positions with installation mortar 7, and were connected at the intersections with cast-in-place concrete 8 to construct the foundation beams.
そして、取出筋が突出していれば、成形梁は交

クリート８は信頼性を持つて一体的に結合するこ
とができる。 If the take-out bars protrude, the cast-in-place concrete 8 can be reliably joined together at the intersection of the formed beams both in the intersecting direction and in the extending direction.
本発明においては、鉄筋梁が、曲折線よりなる
彎曲鉄筋と水平鉄筋の端部同士の溶着した弓形鉄
筋の逆向背合せと帯鉄の並列介在の接点の溶着組
立てよりなるから、鉛直等分布荷重に対する合理
的構造となつて鋼量の節約となる。 In the present invention, since the reinforcing bar beam is constructed by welding and assembling the contact points of the curved reinforcing bars made of curved lines and the arcuate reinforcing bars welded together at the ends of the horizontal reinforcing bars in opposite directions and the parallel intervening points of band iron, the vertically evenly distributed load can be applied. It has a rational structure and saves the amount of steel.
本発明においては、鉄筋梁を可塑性材料で被覆
成形して成形梁を形成したから、鉄筋梁を保護す
る許りでなく、その剛性保持と坐屈防止の効は確
実である。 In the present invention, since the reinforced beam is coated and molded with a plastic material to form a shaped beam, it not only protects the reinforced beam but also ensures its rigidity retention and buckling prevention effects.
本発明においては、鉄筋梁、成形梁は工場生産
によるもので、プレキヤスト化されているから、
現場施工に較べ、経済的である。 In the present invention, the reinforcing beams and formed beams are manufactured at a factory and are precast, so
It is more economical than on-site construction.
本発明においては、成形梁の交点での接合部に
現場打ちコンクリートで結合するから、形枠は節
減でき、工期の短縮工費の低減が得られる。 In the present invention, since the joints at the intersections of the formed beams are joined with cast-in-place concrete, the number of forms can be saved, shortening the construction period and reducing construction costs.
本発明においては、各成形梁は相互に確実に連
結し一体的な基礎梁を構成して地盤にも密着する
