本発明は壁に設けた誘発目地部におけるシャーコツター
に関づ−るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shearco starter in a trigger joint provided in a wall.
従来より例えば外壁には誘発目地部を設けたものがある
が、壁筋が誘発目地部に直角に配筋されている揚台には
この壁筋が、亀裂生成を拘束することになって、誘発目
地部としての機能が損われ、また亀裂生成時に壁筋に引
張力が生じて、壁筋が変形し、外壁の品質が劣る問題が
あった。Conventionally, for example, external walls have been provided with inducing joints, but on platforms where wall reinforcements are arranged at right angles to the inducing joints, these wall reinforcements restrict crack formation. There was a problem in that the function as an inducing joint was impaired, and when cracks were generated, tensile force was generated in the wall reinforcement, causing the wall reinforcement to deform, resulting in poor quality of the outer wall.
本発明の目的は、上記の問題を解決するもので、本発明
の特徴は例えば丸鋼と鋼管とを組み合わせて、材軸方向
には壁の伸縮に応じて伸長し、材軸に直角方向にはせん
断耐力のあるシャーコツクーを提供づ−るものである。The purpose of the present invention is to solve the above-mentioned problems, and the feature of the present invention is to combine, for example, a round steel and a steel pipe, so that the material can expand in the direction of the material axis in accordance with the expansion and contraction of the wall, and in the direction perpendicular to the material axis. This provides a shark scoot with shear strength.
以下本発明の一実施例を図面に基づいて説明する。An embodiment of the present invention will be described below based on the drawings.

孔の長さを所定のものに設定しである。In FIGS. 1 and 2, the Shark Turbine according to the present invention has a shape of a pot in which a Turbine Turbine Base 1 and a Turbine Shaft Body 2 are connected in an elongated manner. The Zunawachi Kotter base body 1 is made of, for example, a steel pipe, and the lower end is compressed by applying pressure from both sides by mechanical means to form a fixing part 3, and this fixing part is formed into an internal insertion hole 4. The lower end opening is sealed and the length of the insertion hole is set to a predetermined value.
またコツター軸部体２は例えば丸鋼で構成し、上部を図
示の例では９♂曲けたフック状の定着部５としである。Further, the rotor shaft body 2 is made of, for example, round steel, and has a hook-shaped fixing portion 5 bent at the top by 9 degrees in the illustrated example.

して、ガタ付きを防止している。Further, the lower part of the footer shaft body 2 is an overlapping portion 2a which is movably inserted and connected into the insertion hole 4 of the turret base body. This overlapping part is coated with a release agent such as grease to reduce the adhesion force with the base body 1. In the inserted state, the gap between the shaft body 1 and the shaft base body 1 at the opening of the insertion hole 4 is filled with cement paste to prevent rattling.
次に使用例について説明する。Next, a usage example will be explained.

．ｉ黄筋５−８と５ｂとの間には何も配筋していな−。In FIG. 3, among the horizontal reinforcements 5 in the wall reinforcement, the reinforcements are placed between one yellow reinforcement 5a and 5b with a large diameter at a predetermined interval that allows the induction joint part 6 to be located, and both horizontal reinforcements 5a, 5b , vertical stripes 7a... and ? b. One end is latched. Note 1
．． i There is no reinforcement between yellow reinforcement 5-8 and 5b.
この状態において、施工される誘発目地部６と直角とな

Ｙ。In this state, a shearcotter is placed between the stone 6 reinforcements 5a and 5b so as to be perpendicular to the induced joint portion 6 to be constructed. That is, the cotter base body 1 is placed on the 6sb side,
The cotter shaft body 2 is disposed on the side of the horizontal reinforcement 5a so as to be orthogonal to the horizontal reinforcement. By doing this, you can mark the arrow ′ on the wall.
Y.
Ｙ１方向の応力、が作用して、シャーコツターに材軸方
向の１芯力がかかつても、シャーコツターは伸長し、こ

誘発目地部の機能が損われない。また矢印Ｘ、ｘ、方向
（材軸に直角方向）の応力に対して、シャーコツターは
せん断耐力を保有し、このため帯筋は変形しない。Even if a stress in the Y1 direction is applied and a single core force in the material axis direction is applied to the shearcotter, the shearcotter will expand, and therefore the generation of cracks in the induced joint portion 6 will not be restrained.
The function of the induced joint area is not impaired. In addition, the shearco starter has shear strength against stress in the direction of the arrow X, x (perpendicular to the material axis), and therefore the ties do not deform.
なお、定着部の構成は、上側の圧縮状のものやフック状
のものに限定されない。Note that the configuration of the fixing section is not limited to the upper compressed type or hook type.
以上説明したように本発明によれば、壁の面内。As explained above, according to the present invention, within the plane of the wall.
