地材装置。[Scope of Claim for Utility Model Registration] A joint bar 2 attached to the inner surface of a formwork 10 for forming a concrete wall W, which can be fitted with the joint bar 2 at one end,
A partition member 3 protruding in the wall thickness direction, a screw shaft 5 for fixing the joint bar 2 and the partition member 3 to the formwork 10, and its inner side 5.
a, middle part 5b. The joint bar 2 includes an inner nut 6, a middle nut 7, and an outer nut 9 which are screwed into the outer part 5c, respectively, and the joint bar 2 has the middle nut 7 at its bottom.
The partition member 3 has a middle nut accommodating recess 16 for accommodating the nut, and the partition member 3 has a pair of partition plates 19 and 19 opposed to each other with a gap between them. A pair of side plates 22, 22, which may widen at the end, are attached to the base end of the partition plate 19, 19.
The joint bar 2 can be inserted between the side plates 22.22, and the anchor flange 25.25 is protruded from the outside of the side plate 22.22 or the partition plate 19.19. Also, on the inner surface of the part where the side plate 22.22 and the partition plate 19.19 are connected or in the vicinity thereof, the side partition plate 19.19 is engaged with the locking part 12.12 at the tip of the joint bar 2. The locking pieces 29 and 29 that prevent the widening of the locking pieces 29 and 29
The locking pieces 29.29 and at least the above-mentioned locking pieces 29.29 are provided on the inner surface of the side partition plate 19.19. It is constructed by providing receiving pieces 31, 31 which receive the tips of the inner side 5a of the screw shaft 5 in abutted state at intervals of the thickness of the inner nut 6, The inner nut 6, which is screwed together and accommodated in the inner nut accommodating portion 32 formed between the locking pieces 29, 29 and the receiving pieces 31, 31, has one threaded groove circumferential surface 33 that is connected to the locking piece. 29.29, and the opposite side surface 34.34 is the partition plate 19.1
9 so that it is held in a state of almost contact and is prevented from rotating,
The partition member 3 and the joint bar 2 can be integrated by tightening the inner nut 6 and the middle nut 7, and the outer nut 9 is screwed into the screw shaft 5 passing through a predetermined portion of the formwork 10. A joint material device characterized in that a joint bar 2 and a partition member 3 can be fixed to a formwork 10 by tightening them.
