従来、耐震壁に開口を形成する場合は、例えば、図２に示すように柱１１及び 大梁１２間に施工される耐震壁１５において、その耐震壁のコンクリート打設に 際し、その開口形成部に適宜の形枠（図示省略）を配置するとともに、その周囲 に多数本の縦横補強筋１６ａ、斜補強筋１６ｂ等を配筋して、コンクリート打設 後にその型枠を撤去して開口１６を形成し、同様に形枠（図示省略）の周囲に多 数本の縦横補強筋１７ａ、斜補強筋１７ｂ等を配筋して、コンクリート打設後に その型枠を撤去して開口１７を形成し、また、必要に応じその開口１６，１７に 周辺枠（図示省略）を装着して形成されている。 Conventionally, when forming an opening in an earthquake-resistant wall, for example, in an earthquake-resistant wall 15 constructed between a column 11 and a girder 12 as shown in FIG. In addition to arranging an appropriate frame (not shown) in the above, arrange a number of vertical and horizontal reinforcing bars 16a, diagonal reinforcing bars 16b, etc. around it and remove the frame after placing the concrete to open the opening 16. Similarly, a plurality of vertical and horizontal reinforcing bars 17a, oblique reinforcing bars 17b, etc. are arranged around the frame (not shown), and after the concrete is placed, the frame is removed to form the opening 17. Further, a peripheral frame (not shown) is attached to the openings 16 and 17 as needed, so that it is formed.

従来、耐震壁に開口を形成する場合は、前記のように開口形成用の型枠の配置 、多数本の補強筋の配筋、型枠の撤去等の面倒な工程、作業となり、また、開口 周囲にコンクリート収縮によるクラツクが生じ易く、開口周辺枠の固着力が低下 して、その開口部が強度上の弱点になるなどの課題がある。 Conventionally, when forming an opening in a seismic wall, it has been a troublesome process and work such as arranging the formwork for forming the opening, arranging a number of reinforcing bars and removing the formwork as described above. There is a problem that cracks are likely to occur due to concrete shrinkage in the surroundings, the fixing force of the frame around the opening decreases, and the opening becomes a weak point in strength.
【０００４】 本考案は、前記のような課題に対処するために開発されたものであつて、その 目的とする処は、耐震壁における開口形成性能及び開口部の強度を向上して耐震 性能を高めた耐震壁の開口補強構造を提供するにある。The present invention has been developed to address the above-mentioned problems, and its purpose is to improve the seismic performance by improving the opening forming performance and the strength of the opening in the seismic wall. It is to provide the opening reinforcement structure of the high earthquake resistant wall.

本考案は、耐震壁に組み込まれて開口の周辺を画成し補強する開口周辺枠と、 同開口周辺枠の外周全域にわたり立植されて開口周囲のコンクリートに埋設され る多数のスタツドボルトを具備したことにより、開口周辺の画成とともにその周 囲のコンクリート収縮を効果的に防止し、また、耐震壁の開口部欠損を効果的に 防止し補強している。 The present invention is provided with an opening peripheral frame which is incorporated into an earthquake resistant wall to define and reinforce the periphery of the opening, and a large number of stud bolts which are planted all over the outer periphery of the opening peripheral frame and embedded in concrete around the opening. By doing so, it is possible to effectively prevent the shrinkage of concrete around the opening as well as the surrounding area of the opening, and also effectively prevent and reinforce the opening of the seismic wall.

耐震壁のコンクリート打設に際し、その開口周辺部に開口周辺枠を配置すると 、その開口周辺枠により開口の周辺が容易に精度良く画成されるとともに、その 開口周辺枠の外周全域に立植されている多数のスタツドボルトが、開口周囲のコ ンクリート内に埋設されてそのコンクリート収縮が効果的に防止され、開口周辺 枠が開口周囲のコンクリートに密着されて、耐震壁の開口部欠損による強度の低 下が効果的に防止され補強されている。 When placing a concrete frame on an earthquake-resistant wall, by placing a frame around the opening around the opening, the frame around the opening can be easily and accurately defined by the frame around the opening and can be planted all over the outer circumference of the frame around the opening. A large number of stud bolts are embedded in the concrete around the opening to effectively prevent shrinkage of the concrete, and the frame around the opening is in close contact with the concrete around the opening, and the strength of the earthquake-proof wall due to the opening defect is reduced. The depression is effectively prevented and reinforced.
