求められている。2. Description of the Related Art Conventionally, walls of reinforced concrete structures,
A seismic slit is buried near the connection with the pillar connected to the wall so as to penetrate the wall, and when an earthquake occurs, the seismic slit acts as a cushioning material to separate the wall from the pillar. Thus, a method for avoiding shear fracture of a column is known. The burying of this seismic slit in a reinforced concrete structure is arranged between the formwork that is erected opposite to construct the vicinity of the connection between the wall and the column, and this is fixed to the formwork, Next, concrete is poured between the molds, and after the concrete is cured for a predetermined time, the mold is removed. As described above, the seismic slits are installed between the formwork when constructing the formwork, so that the installation work is easy, and after the installation, the slit is easily displaced or pushed out by the pressure of the cast concrete. It is required to be firmly fixed to the formwork so that it does not fall off.

いる。[0003] Various techniques have been proposed to satisfy these requirements. For example, Japanese Utility Model Application Laid-Open No. 60-61331 discloses a slit support plate on which a slit material is mounted, which has a support arm protruding along the axial direction of the wall on one side thereof, and is inserted near the tip of the support arm. There is disclosed a slit material support device configured to detachably mount a through-hole to the insertion hole. Further, a plate-shaped core material, and a pair of reinforcing support members fitted to each side end of the core material, the outer ends of which are fixed to the mold, are provided. Also disclosed is an earthquake-resistant slit in which a concave portion is formed and the concave portion is fitted to a fixing member fixed to a mold.

Push up. Further, when the slit material is constructed between the molds, there is a problem that there is a troublesome operation for inserting the rod member of the separator into the insertion cylinder. In addition, the seismic slit having a pair of reinforcing support members whose outer ends are fixed to the formwork needs to be firmly fixed to the formwork so as not to be easily displaced by the pressure of the poured concrete. Inevitably, the depth of the concave portions of the pair of reinforcing support members formed at the respective side ends must be large. Usually, the material of the reinforcing support member is made of hard vinyl chloride, and there is a problem that the use of the reinforcing support member having a large depth of the concave portion also increases the cost.

きることなどを見出し、本発明を完成するに至った。Under such circumstances, the present inventors have made intensive studies and as a result, have found that a steady rest is embedded in the wall so as to run along the axial direction of the wall and penetrates the slit for earthquake resistance. And, a separator that is passed in order to maintain the spacing of the formwork is arranged close to each other, and if the cross section of the steady rest and the separator is fixed with, for example, a connecting bracket, the steady rest is formed. Not only the function of simply preventing the wall from swaying, but also the reinforcing material for fixing the position of the seismic slit, it is not necessary to provide a reinforcing metal such as a support arm, and the cost can be reduced.
Since the connection between the steady rest and the separator can be performed by dropping a U-shaped connection fitting at these intersections,
The present inventors have found that it is possible to easily and firmly attach the slit for earthquake resistance between the molds, and have completed the present invention.
