Claims

[Scope of utility model registration request]

One end surface of the large-diameter columnar body 1 is provided with a male threaded rod 2 to be screwed into a female screw hole M of a fastening member F outside the formwork K. In the seat body in which a female threaded hole 3 to be screwed into the male threaded end N of the intermediate connecting fitting C is recessed, the male threaded rod 2 integrally projects into the columnar body 1 via the small diameter portion 4. The small diameter portion 4 is directly connected to the one end surface of the columnar body 1, and the male threaded rod 2 of the small diameter portion 4 is connected directly to the one end surface of the columnar main body 1.
A concrete formwork clamping seat for construction work, characterized in that its length in the axial direction is sufficiently small compared to its diameter.
