BEAM FORMING MEMBER AND STEEL-REINFORCED CONCRETE BEAM MEMBER

To provide a beam forming member capable of improving construction efficiency by downsizing and reducing weight when forming an outer shell of a steel-reinforced concrete beam member.SOLUTION: Beam forming members 12 are made of pre-cast concrete in a generally L-letter shape and are placed parallely in a pair. The beam forming member 12 is provided with joint fixtures 40 apart in a specific interval from each other along a longitudinal direction. According to the present invention, construction efficiency of the steel-reinforced beam member 1 is improved by downsizing the beam forming member 12 of a pre-cast concrete member and reducing its weight through assembling the beam forming members 12 of a pair of the pre-cast concrete members in a generally L-letter shape without using a single pre-cast concrete member upon forming a beam outer shell 10 of the steel-reinforced beam member 1.SELECTED DRAWING: Figure 1 【課題】鉄筋コンクリート梁部材の外殻を形成する際に、小型化および軽量化して施工効率を向上できる、梁形成部材を提供すること。【解決手段】梁形成部材１２は、断面略Ｌ字形状でプレキャストコンクリート製であり、一対並列に配置される。この梁形成部材１２には、長さ方向に沿って所定間隔おきに連結金物４０が設けられる。本発明によれば、鉄筋コンクリート梁部材１の梁外殻部１０を形成する際に、単一のプレキャストコンクリート部材を用いるのではなく、一対の略Ｌ字形状のプレキャストコンクリート部材である梁形成部材１２を組み合わせることで、プレキャストコンクリート部材である梁形成部材１２を小型化および軽量化して、鉄筋コンクリート梁部材１の施工効率を高めることができる。【選択図】図１
