シール材３７の保着部としても機能する。 The partition member 3 has a length that can induce cracks to completely insulate the walls between the columns and the columns when vibrations above a certain level are applied to the concrete wall during an earthquake, and preferably have a length that can induce cracks to completely insulate the walls between the columns and the columns. The length is set to be at least about 40% or more of the thickness of the wall to be coated, and in this embodiment, the length is set to about 50% or more. The partition member 3 includes a pair of partition plates 19, 19 facing each other in parallel with a relatively small interval.
The distal ends of the partition plates 19, 19 are integrally connected by a joint 21 in which part, in this embodiment, the central part is made of a flexible synthetic resin elastic part 20 spanning the entire length in the longitudinal direction, and the proximal ends of the partition plates 19, 19 In this case, a pair of side plates 22, 22 which widen toward the end are integrally arranged in series toward the formwork 10, and the joint bar 2 can be inserted between the side plates 22, 22. On the outer surface near the base end of the partition plates 19, 19, anchor flanges 25, 25 having an anchor protrusion 23 at the tip that protrudes toward the formwork 10 are protruded, and side plates 22, 22 are provided.
L-shaped locking pieces 29, 29 consisting of a projecting piece 26 and a bent piece 27 are provided protrudingly on the inner surface of the connecting portion between the partition plates 19, 19 and the partition plates 19, 19. The locking portion 1 of the joint bar 5 is located between the side plates 22, 22.
2 and 12 are formed. Therefore, by engaging the locking portion 12 and the locking groove 30, widening of both the partition plates 19, 19 is prevented. The locking pieces 29, 29 are provided in a protruding manner such that a gap g is formed between the bent pieces 27, 27 through which the screw shaft 5 can be inserted. In this embodiment, when the joint bar 2 is inserted between the side plates 22, 22, the tips 2 of the side plates 22, 22
2a, 22a are set to be located slightly away from the proximal ends of the side pieces 15, 15 of the joint bar 2. Further, the inner surfaces of both the partition plates 19, 19 are provided with the locking pieces 29, 29 and at least the inner nut 6.
The receiving pieces 31, 31 that receive the tips of the inner side 5a of the screw shaft 5 are butted against each other with a small gap at a distance relatively larger than the thickness (threaded into the inner side 5a of the screw shaft 5). An inner nut accommodating portion 32 is formed between the locking pieces 29, 29 and the receiving pieces 31, 31. The inner nut 6 accommodated in the inner nut accommodating portion 32 has one threaded groove circumferential surface 33 that is connected to the locking piece 2.
9 and 29, and as shown in FIG. 3, the opposing sides 34,
34 is held between the partition plates 19, 19 in a substantially contacting state and is prevented from rotating. Therefore, when the inner nut 6 is accommodated in the inner nut accommodating portion 32, the screw shaft 5 (the number of which is equal to the number of through holes 17 arranged in parallel in the joint bar 2), which has an inner nut 6 screwed into the inner side portion 5a in advance, is inserted into the inner nut accommodating portion 32. It is attached to the partition member 3 through the gap g so that the
When the joint bar 2 is inserted between the side plates 22 and 22 and each screw shaft 5 is inserted into the corresponding through hole 17,
The engagement between the locking portion 12 and the locking groove 30 prevents the partition plates 19, 19 from widening, and the inner nut 6
is blocked by both partition plates 19, 19 and is prevented from rotating. In this state, when the screw shaft 5 is rotated in the spiraling direction of the inner nut 6, since the inner nut 6 is prevented from rotating as described above, the tip of the inner part 5a of the screw shaft 5 is inserted into the receiving pieces 31, 31. The inner nut 6 moves forward and the tip comes into contact with the receiving pieces 31, 31.
One of the threaded peripheral surfaces 33 is brought into pressure contact with the projecting pieces 26, 26 of the locking pieces 29, 29, and the partition member 3 and the screw shaft 5 are integrated. In this state, the partition member 3, the joint bar 2, and the screw shaft 5 can be integrated by tightening with the inner nut 7, and the outer part 5c of each screw shaft 5 can be attached to the formwork 1 located on the outdoor side.
By inserting the joint bar 2 into a predetermined through hole 35 of 0, screwing the outer nut 9 onto the outer part 5c of the screw shaft 5, and tightening the outer nut 9, the joint bar 2 and the partition member 3 are integrally molded. The partition member 3 is fixed to the frame 10 and protrudes in the wall thickness direction, and its tip portion is located slightly beyond the center of the thickness of the wall W to be formed, as shown in FIG. In this state, concrete is poured between the forms, and after the concrete hardens, the outer nut 9 and screw shaft 5 are rotated in the opposite direction to remove them (at this time, since the inner nut 6 is prevented from rotating, the screw shaft 5 is rotated in the opposite direction). When the mold is demolded and the joint rod 2 is removed, the wall W becomes as shown in Fig. 4.
The area from the outdoor side to a portion slightly beyond the center of the wall W is insulated by the partition member 3. Note that the joint groove 36 formed on the outdoor wall surface is filled with a sealing material 37. When filling the sealing material 37, the receiving pieces 31, 31 also function as backup materials, and the locking pieces 29, 29 also function as holding parts for the sealing material 37.

る建築物の破壊を防止することができる。 In this way, in the joint filling device 1 of the present invention, since the partition member 3 insulates the connecting part between the column p and the wall W over a wide range, if vibrations below a certain level are applied to the wall W during an earthquake, As shown in FIG. 4, the partition member 3 induces a crack 39 extending from its tip to the indoor wall surface of the wall W in the direction in which the partition member 3 protrudes. the result,
Since the wall W and the column p are completely insulated, the stress of the wall W hardly acts on the column p, which gives stickiness to the column p and prevents the building from breaking due to breakage of the column p. can be prevented.

る。 The left and right partition plates 19, 19 of the partition member 3 are connected only by a joint piece 21, and a part of the joint piece 21 is connected to an extendable part 20 over the entire length in the longitudinal direction.
Therefore, the partition member 3 can be expanded and contracted in the width direction of the joint. Therefore, the partition member 3 can be expanded and contracted in accordance with the expansion and contraction of the joint due to the expansion and contraction of the concrete, and the partition member 3 can be completely closed from rain at the joint. It is possible to secure the following. As shown in the embodiment, the side plates 22, 22 are arranged so that the tips 22a, 22a of the side plates 22, 22 are located at a position away from the wall surface.
If the dimensions of the joint rods 2 and 2 are set, the partition member 3 will no longer be able to sufficiently follow the expansion and contraction of the concrete due to the deterioration of the expansion and contraction portion 20, and the side plates 22,
Even if there is a gap between the tip 22 and the concrete, as shown in FIG.
By filling the sealing material 37 in a state where the joints 2a and 22a are buried, it is possible to ensure that the joints are protected from rain. At that time, the anchor flange portions 25, 25
Since it also functions as a water stop plate, even if rainwater enters through the gap, the intruding water is reliably stopped by the anchor flanges 25, 25.

The information can be reliably transmitted to the partition member 3 through the media. In this embodiment, since the anchor flange 25 has the anchor protrusion 23 at its tip, expansion and contraction of the concrete can be transmitted to the partition member 3 more reliably.

工の簡易化、能率化を期しうる。 Since it is possible to integrate the joint bar 2, the partition member 3, and the screw shaft 5 in advance using the inner nut 6 and the middle nut 7 at the time of shipment, the outer part 5c of the screw shaft 5 can be easily attached at the construction site. By inserting the joint bar 2 into the through hole 35 provided in the formwork 10,
and the partition member 3 can be easily and quickly attached to the formwork 10, resulting in excellent workability. By tightening the outer nut 9 that is screwed onto the screw shaft 5, the joint bar 2 and the partition member 3 are fixed to the formwork 10, so that the long protruding partition member 3 can be firmly and reliably fixed. It can be fixed to the formwork 10, and therefore, when concrete is placed between the formworks, the joint material has sufficient strength against the casting pressure. In addition, the inner nut 6 screwed onto the inner side 5a of the screw shaft 5 is housed in the partition member 3 in a non-rotating state, and the partition member 3 has a receiver for receiving the tip of the inner side 5a of the screw shaft 5. Since the piece 31 is provided, the installation and removal of the screw shaft 5 and the tightening of the inner, middle, and outer nuts 6, 7, and 9 are made extremely easy, and the installation of the joint material to the formwork is simplified. It can be expected to improve efficiency.
