ANGLE BRACE, AND EARTH RETAINING TIMBERING STRUCTURE
To provide an angle brace and an earth retaining timbering structure that can improve efficiency of each work inside an excavation tunnel compared to conventional methods and reduce temporary construction costs related to a short strut type timbering.SOLUTION: An angle brace includes: a first angle tie receiving member 33A abutted against one wale 2A and capable of withstanding a shear force generated between the one wale and itself; a second angle tie receiving member 33B abutted against the other wale 2B and capable of withstanding a tensile force generated between the other wale and itself; and a main angle tie member 31 having a predetermined bending rigidity, having one end to which the first angle tie receiving member is connected and the other end to which the second angle tie receiving member is connected. The main angle tie member has an H-shaped cross-section and is a prefabricated earth retaining main member that is equipped with an end plate 313 having bolt holes 314 at the one end and the other end and that can be used repeatedly.SELECTED DRAWING: Figure 3
【課題】従来よりも掘削抗内における各作業効率を向上させるとともに、切梁式支保工に係る仮設費の低減を図ることがと可能な、火打ち梁及び山留め支保構造を提供する。【解決手段】一方の腹起し２Ａに突き合わされるとともに該一方の腹起しとの間で生じるせん断力に抗することが可能な第一火打ち受け部材３３Ａと、他方の腹起し２Ｂに突き合わされるとともに該他方の腹起しとの間で生じる引張力に抗することが可能な第二火打ち受け部材３３Ｂと、所定の曲げ剛性を有するとともに一方の端部に前記第一火打ち受け部材が結合され、他方の端部に前記第二火打ち受け部材が結合される火打ち主材３１と、を有し、前記火打ち主材は、Ｈ型断面を有するとともに前記一方の端部及び前記他方の端部にボルト孔３１４を有するエンドプレート３１３を備えて繰り返し使用することが可能な既成山留め主材であることを特徴とする。【選択図】図３
