PURPOSE:To facilitate the attaching of a base frame supporting member to the abdomen of a T-girder by providing an anchor base member fixed to the abdominal section of the T-girder and a constructing member supporting anchor member to hold a constructing member. CONSTITUTION:An anchor device 23 is formed of an anchor base member 24 and a square timber supporting anchor member 25 being a constructing member supporting anchor member to hold a wooden square timber 28. Next, a bolt inserted through an attaching hole 30 provided on the base member 24 is screwed into a ceramic insert inside the abdomen 22 of each T-girder 1 for fixing the device 23 to each abdomen 22. The square timber 28 is then constructed over the member 25, and a nail is driven from the outside of the square timber 28, which is thereby fixed so as not to move among the abdomen 22, the member 25 and a holding plate 27. Both the ends of a base frame supporting member 41 are supported on each square timber 28, and a base frame 43 is set up above the supporting member 41 through a bearing member 42 and positioned so as to close the lower part of a gap G between the floor plates 21a of each girder 21. Thus the supporting member 41 can be easily attached. |
