いる。2. Description of the Related Art Conventionally, a concrete wall has been widely used as an outer wall material of a house or the like. The concrete wall is fixed and attached at a plurality of points along an H-shaped steel body supported between columns of a building. The method is generally known.

できる。Concrete walls are disclosed, for example, in Japanese Patent Laid-Open No.
As described in JP-A-194146, a joining member for attaching to an H-shaped steel body is buried at a total of four places, at least two places above and below the concrete wall. The embedded joining member is cylindrical and has an internal thread on the inner circumference.
Then, a bolt penetrating through the hole of the connecting member fixed to the H-shaped steel body was screwed into the female screw of this joining member, and the concrete wall was attached to the H-shaped steel body. Therefore, by embedding this joining member in the concrete wall, the concrete wall can be easily attached to the H-shaped steel body.

ォールから抜ける等の問題が発生する恐れがあった。However, since the weight of the concrete wall is always applied to the joining member embedded in the concrete wall and the external pressure such as wind is also applied, a great load is applied in the axial direction of the joining member. On the other hand, since the joining member has a cylindrical shape, if a load in the axial direction is received for a long period of time, the joining force of the joining member with the concrete wall will decrease, the joining member will move in the axial direction, and will further escape from the concrete wall. There was a risk that problems such as

ることができる。Therefore, it is conceivable to use the joining member 101 as shown in FIGS. 12 and 13 in order to prevent the joining member from moving in the axial direction. The joining member 101 is composed of a cylindrical main body 106 and a flange portion 105 extending circumferentially from one end 104 of the main body 106, and an internal thread 107 with which a bolt is screwed is provided on the inner periphery of the main body 106. Has been. Therefore, with respect to the axial load of the joining member 101, the collar portion 1
05 receives the load, and the movement of the joining member 101 can be suppressed.

荷重を受けないということがある。However, the above-mentioned joining member 1
In No. 01, since the flange 105 is formed on the one end 104, the flange 105 receives the load against the load on the flange side, especially when the joining member 101 penetrates the concrete wall. There is a case where the counter-collar portion 105 does not receive a load against the load on the side.

A joining member 201 including a first flange portion 203 and a second flange portion 205 that circumferentially extend at both end portions 202 and 204 of 6 is conceivable. By using this joining member 201, the movement in the axial direction is completely suppressed.

No. 1 has a problem when it is buried in a concrete wall. That is, as shown in FIG. 16, the concrete wall 2
When molding 41, the joining member 201 is arranged at a predetermined position of the mold 251 in advance, and then concrete is poured and molded. At this time, the concrete is poured into the entire form 251, but the joining member 201 has its both end portions 202,
Since the flange 204 has the flanges 203 and 205, the joining member 2
It is difficult for concrete to be sufficiently filled in the outer peripheral space of the main body 206 of 01, and the concrete main body 242 and the joining member 20
There may be a case where a thin wall space 243 is generated between the first and second parts, which may lead to rattling of the joining member 201 and deterioration of durability.
