BACKGROUND OF THE INVENTION When a cloth foundation for a building is formed using precast concrete (PC concrete) and installed on site, it is necessary to join the installed PC concrete members to each other. Figures 5 and 6 show such a conventional joint structure, in which bolts are pre-installed in the foundation concrete (3) of a predetermined size, which consists of a cloth part (1) and a footing part (2). (4) (4) are buried in a protruding state, and tongue buckle type screws (7) (5) are screwed into these bolts (4) (4) to connect them to each other. .

Problems to be Solved by the Invention In the above tongue buckle type joining structure, Nantes (5
) (4) When screwing into (4), one PC concrete member (3) must be moved according to the amount of movement of the screw pinch as this nut (5) is rotated. However, there is a drawback that it is extremely difficult to move according to the pitch. In addition, the rotation operation of Nando (5) needs to be rotated in the transverse direction of the PC concrete member (3), and even if there was enough tool clearance between both PC concrete members to rotate the Nando. However, this has the disadvantage that it must be rotated through the gap between both PC concrete members, making the rotation work of the naphto (5) that much more difficult.

Effects of the Invention As described above, according to the present invention, it is only necessary to install each PC concrete member to be joined at the joining position and tighten the connecting member from above with a bolt, which is different from the conventional tongue buckle type. As such, there is no need to move the PC concrete members closer to each other depending on the amount of rotation of the nut, which has the effect of greatly facilitating the joining work. In addition, since the bolt or nut can be rotated in order to apply tightening force by rotating it horizontally from above, it is compared to a tongue buckle type that rotates in the transverse direction of the prestressed concrete member. Therefore, such tightening work is very easy. Furthermore, in cases where the connecting plate is simply screwed into each fixing plate with bolts to connect them, it is necessary to match the bolt holes of the connecting plate and the bolt holes of the fixing plate completely from the beginning. , in this invention,
Since the error in the installation position of each PC concrete member is absorbed by the pressing surface of the inclined or curved joint surface, there is an effect that there is no need to precisely install each PC concrete member.
