【発明が解決しようとする課題】
ところで、架構に耐震壁を増設する場合、例えば建物を使用しながらの補強工事を行なうことがあり、図１１に示す在来工法及び図１２に示すプレキャスト工法では、架構の境界部に目粗しを行ない、後打ちアンカー後に耐震壁を構築するため、目粗しや後打ちアンカーの施工では騒音の発生やほこり等による汚れは必須である。さらに、後打ちアンカーは架構の主筋位置より内部に打ち込む必要があるが、アンカー打ちでは架構内の鉄筋位置を特定できないために、鉄筋に当たってしまうことがかなり多く、施工上良い状態とは言えず、施工品質を確保しにくい。また、図１３に示す工法では、プレキャストコンクリートが重いために、後打ちアンカーや支持材が必要となるし、作業性が悪い等の問題がある。

[Problems to be solved by the invention]
By the way, when adding a seismic wall to a frame, for example, reinforcement work may be performed while using a building. In the conventional method shown in FIG. 11 and the precast method shown in FIG. the line stomach, to build earthquake-resistant wall after the post-deposited anchor, dirt is essential due to the occurrence and the dust of the noise at the construction of roughening and post-deposited anchor. In addition, the post-fixed anchor needs to be driven in from the position of the main bar of the frame, but since the position of the reinforcing bar in the frame cannot be specified by anchoring, it often hits the bar, which is not a good state for construction. It is difficult to ensure construction quality. Further, in the construction method shown in FIG. 13, since the precast concrete is heavy, there is a problem that post-casting anchors and supporting materials are required, and workability is poor.
請求項１記載の発明では、架構の境界部に、増設壁側にアンカーを有する鋼板を接着剤により接合することで、目粗しや後打ちアンカーの施工をなくすことができ、騒音の低下やほこり等による汚染の低減が可能で、さらに鋼板取付の施工品質の確保が容易である。また、接合部を介して架構に耐震壁を増設し、この接合部の鋼板は増設壁側のアンカーを有しており、このアンカーにより架構と増設壁側との応力伝達（剪断、曲げ、及び引張力等）に対応できる接合の補強を行なうことができる。 In the invention according to claim 1, by joining a steel plate having an anchor on the additional wall side to the boundary portion of the frame with an adhesive, it is possible to eliminate roughening and post-fixed anchor construction, noise reduction and Contamination due to dust and the like can be reduced, and it is easy to secure the construction quality of the steel plate attachment. In addition, a seismic wall is added to the frame through the joint, and the steel plate of this joint has an anchor on the side of the additional wall, and stress transmission (shearing, bending, and the reinforcement of the bonding to accommodate tensile forces, etc.) row of Ukoto.
請求項４記載の発明では、増設壁側のアンカーが、スタッドボルト、または鉄筋、または型鋼であり、鋼板に溶接等により簡単且つ強固に固定することができ、しかもスタッドボルト、または鉄筋、または型鋼により架構と増設壁側との応力伝達（剪断、曲げ、及び引張力等）に対応できる接合の補強を行なうことができる。 In the invention according to claim 4, the anchor on the side of the additional wall is a stud bolt, a reinforcing bar, or a steel plate, and can be easily and firmly fixed to the steel plate by welding or the like, and the stud bolt, the reinforcing bar, or the steel plate. the stress transfer between the Frame and expansion wall (shear, bending, and tensile force, etc.) to reinforce the joint to accommodate can line a Ukoto.
次に、鋼板７の周辺を固練りエポキシ樹脂系の接着剤でシールし、このシール後に、シール内側の鋼板７と架構４の境界部の表面との間にエポキシ樹脂系の接着剤８の充填を行ない、鋼板７を架構４の境界部の表面にエポキシ樹脂系の接着剤８により接合する。 Next, the periphery of the steel plate 7 is kneaded and sealed with an epoxy resin adhesive, and after this sealing, the epoxy resin adhesive 8 is filled between the steel plate 7 inside the seal and the surface of the boundary portion of the frame 4. the rows that have, the steel sheet 7 are bonded by adhesive 8 of an epoxy resin on the surface of the boundary of Frame 4.
このように架構４の境界部に、増設壁側にアンカー６を有する鋼板７をエポキシ樹脂系の接着剤８により接合することで、目粗しや後打ちアンカーの施工をなくすことができ、騒音の低下やほこり等による汚染の低減が可能で、さらに鋼板７取付の施工品質の確保が容易である。また、接合部９を介して架構４に耐震壁５を増設し、この接合部９の鋼板７は増設壁側のアンカー６を有しており、このアンカー６により架構４と増設壁側との応力伝達（剪断、曲げ、及び引張力等）に対応できる接合の補強を行なうことができる。 In this way, by joining the steel plate 7 having the anchor 6 on the additional wall side to the boundary portion of the frame 4 with the epoxy resin adhesive 8, it is possible to eliminate roughening and post-fixed anchor construction, and noise. It is possible to reduce contamination due to lowering of dust, dust and the like, and it is easy to secure the construction quality of the steel plate 7 attachment. Further, the seismic wall 5 is added to the frame 4 via the joint 9, and the steel plate 7 of the joint 9 has an anchor 6 on the side of the additional wall, and the anchor 6 connects the frame 4 and the additional wall side. stress transfer (shear, bending, and tensile force, etc.) to reinforce the joint to accommodate can line a Ukoto.
鋼板７の増設壁側のアンカー６は、スタッドボルト６０の他に、図７及び図８に示すように鉄筋を屈曲して溶接したループ筋６１等の鉄筋で構成してもよく、図９及び図１０に示すように一部を溶接して固定したＬ型鋼６２等の型鋼で構成してもよい。このように増設壁側のアンカー６が、スタッドボルト６０、またはループ筋６１等の鉄筋、またはＬ型鋼６２等の型鋼により簡単且つ強固に固定することができ、しかもスタッドボルト６０、またはループ筋６１の鉄筋、またはＬ型鋼６２等の型鋼を用いることで、架構４と増設壁側との応力伝達（剪断、曲げ、及び引張力等）に対応できる接合の補強を行なうことができる。 The anchor 6 on the side of the additional wall of the steel plate 7 may be constituted by a reinforcing bar such as a loop bar 61 in which the reinforcing bar is bent and welded as shown in FIGS. As shown in FIG. 10, you may comprise shape steels, such as L shape steel 62 fixed by welding a part. As described above, the anchor 6 on the additional wall side can be easily and firmly fixed to the stud bolt 60 or the reinforcing bar such as the loop bar 61, or the steel plate such as the L-shaped steel 62, and the stud bolt 60 or the loop bar 61. by using a rebar or shape steel such as L-type steel 62, the stress transfer between Frames 4 and expansion wall (shear, bending, and tensile force, etc.) to reinforce the joint to accommodate it can line a Ukoto.
