AUXILIARY FRAME BODY AND SIMPLE SPRAY SLOPE FRAME METHOD

PROBLEM TO BE SOLVED: To provide an auxiliary frame body capable of easily executing installation work to a reinforcement, easily coping with unevenness, capable of stably holding a surface of a steel plate, and capable of coping with even a case of being one in the reinforcement arranged in a lattice shape.SOLUTION: In a simple spray slope face method, an auxiliary frame body 1 held in a predetermined height position between a slope face and itself, used by being installed on a reinforcement 10A arranged in a lattice shape and buried together with the reinforcements 10A and 10B in sprayed mortar M, is constituted of a steel plate 2 and a plurality of connection members 3 for connecting the steel plate 2 to the reinforcement 10A and separated in the long side direction of the steel plate 2. The connection members 3 are composed of a vertical line part 4 arranged along the short side direction of the steel plate 2, an inclined line part 5 of extending obliquely upward from a lower end part of the vertical line part 4 and a hook-shaped line part 6 provided in an upper end part of the inclined line part 5. At least upper-lower two places of the vertical line part 4 are connected to the steel plate 2, and are installed by fixing the hook-shaped line part 6 to the one reinforcement 10A.SELECTED DRAWING: Figure 3 【課題】鉄筋への取付作業を容易に行うことができ、不陸に対応しやすく、網板の面を安定して保持できるとともに、格子状に配された鉄筋が１本の場合にも対応できる補助枠体を提供する。【解決手段】簡易吹付法枠工法において、法面との間で所定高さ位置に保持されるとともに格子状に配された鉄筋１０Ａに取り付けて使用され、吹き付けられるモルタルＭに鉄筋１０Ａ，１０Ｂとともに埋設される補助枠体１であって、網板２及び網板２を鉄筋１０Ａに連結する、網板２の長辺方向に離間した複数の連結部材３により構成される。連結部材３が、網板２の短辺方向に沿って配置される縦線部４と、縦線部４の下端部から斜め上方へ延びる傾斜線部５と、傾斜線部５の上端部に設けた鉤状線部６とからなる。縦線部４の少なくとも上下２箇所が網板２に連結され、鉤状線部６を１本の鉄筋１０Ａに掛止することより取り付けられる。【選択図】図３
