Description

本発明は、既設の鉄筋コンクリート柱に新たな鉄筋コンクリート梁を接合する柱梁接合工法、及び既設の鉄筋コンクリート柱に新たに鉄筋コンクリート梁を設置した柱梁接合構造に関する。   The present invention relates to a column beam joining method for joining a new reinforced concrete beam to an existing reinforced concrete column, and a column beam joining structure in which a reinforced concrete beam is newly installed on an existing reinforced concrete column.

例えば、耐震補強工事等で、既設の鉄筋コンクリート柱に鉄筋コンクリート梁を新たに増設する場合、その新たな鉄筋コンクリート梁の主筋を、既設の鉄筋コンクリート柱に定着させる必要がある。その際、従来では、既設の鉄筋コンクリート柱に後施工アンカーを打設し、その後施工アンカーを介して、増設する梁の主筋を、既設の鉄筋コンクリート柱に定着させている。
尚、この様な従来技術に関しては、当業者の間で広く知られているものであり、詳しく言及した特許文献などが無いため、先行技術文献を開示できない。 For example, when a new reinforced concrete beam is newly added to an existing reinforced concrete column due to seismic reinforcement work or the like, it is necessary to fix the main bar of the new reinforced concrete beam to the existing reinforced concrete column. At that time, conventionally, a post-construction anchor is placed on an existing reinforced concrete column, and then the main reinforcement of the beam to be added is fixed to the existing reinforced concrete column via the construction anchor.
Such a prior art is widely known among those skilled in the art, and since there is no patent document or the like that is mentioned in detail, a prior art document cannot be disclosed.

しかしながら、上記従来工法によれば、建築基準法の規制により、打設する後施工アンカーの設置間隔を、増設する梁の通常の主筋間隔よりも広く設定しなければならない場合が多い。即ち、図７に示すように、増設する梁２の主筋４の設置間隔ｔ（設置間隔ｔは、等間隔でなくとも良い）を、後施工アンカー（尚、図７においては、梁２から延出している主筋４の延長部分が後施工アンカーに相当するものである）の設置間隔Ｔに合わせる必要があるため、増設する梁２の太さが必要以上に大きくなり、コンクリート等の材料コストの増大や、工期長期化の原因となるなど、建築計画上の種々の不都合が生じている。   However, according to the above-mentioned conventional construction method, the installation interval of post-installed anchors to be placed often has to be set wider than the normal main bar interval of the beam to be added due to the regulations of the Building Standard Law. That is, as shown in FIG. 7, the installation interval t of the main bars 4 of the beam 2 to be added (the installation interval t may not be equal) is set to the post-construction anchor (in FIG. 7, it is extended from the beam 2). The extension of the main reinforcing bar 4 is equivalent to the post-installed anchor), so that the thickness of the beam 2 to be added becomes larger than necessary, and the cost of materials such as concrete is reduced. There are various inconveniences in building planning, such as an increase and a long construction period.

本発明は、上記実情に鑑みてなされたものであって、増設する鉄筋コンクリート梁の太さを必要以上に大きくすることのない柱梁接合工法及び柱梁接合構造を提供するものである。   The present invention has been made in view of the above circumstances, and provides a column beam joining method and a column beam joining structure in which the thickness of the reinforced concrete beam to be added is not increased more than necessary.
