| 摘要 |
The present invention relates to a method of constructing a prefabricated nodular box-shaped girder by assembling separate nodules and web members which are respectively fabricated by precast concrete members in advance to manufacture the girder having a box-shaped cross section, in which the nodules and the web member are easily engaged to each other in view of an manufacture allowance and a construction allowance, thereby quickly and economically manufacturing the box-shaped girder, and a prefabricated nodular box-shaped girder manufactured by the method. A nodule (10) and a J-shaped web member (20) made of precast concrete are alternatively placed in a longitudinal direction, in which the nodule is formed in a box shape, and has through-portions (130) and a partition (134) formed at a lower end of the through-portion (130), the partition being formed with an insertion hole (135) penetrating in a longitudinal direction. The cross section of the J-shaped web member (20) is fitted into the through-hole (130) of the nodule (10) so that a fixing member (28) is inserted into the insertion hole (135) of the partition (134). A curing agent is filled and cured in the through-portion (130), and concrete is placed between lower portions of the J-shaped web members (20) and between lower transverse portions (14) of the nodules (10), thereby forming a bottom portion (60). |
