Description

この発明は、木造その他の家屋の耐震補強体に関する。 The present invention relates to a seismic reinforcement body for wooden or other houses.

一般家屋の耐震補強工事として、建物内部の軸組み内に新たな筋交いや壁を増設することが行われている（非特許文献１）。 この補強方法の場合、建物内に立ち入る必要があり、居住者の生活に多大な不便を来たすことになる他、直接の補強工事以外に既存の部屋の間取りや模様替え、仕上げ材の撤去や復旧などの付帯工事にかなりの費用が発生する。 このようなことから耐震診断によって耐震補強が必要とされる住宅であっても補強工事が実施されていないのが現状である。 As a seismic reinforcement work for ordinary houses, new braces and walls have been added to the frame inside the building (Non-Patent Document 1). In the case of this reinforcement method, it is necessary to enter the building, which will cause great inconvenience to the lives of residents, and in addition to direct reinforcement work, the floor plan and redesign of existing rooms, removal and restoration of finishing materials, etc. There will be considerable costs for incidental construction. For these reasons, the current situation is that no reinforcement work has been carried out even in houses where seismic reinforcement is required by seismic diagnosis.

本発明は、建物隅部の外側２面に、補強壁を直角に配設して、既存の構造材に固定することによって震度６程度の地震にも倒壊しない補強体を提供するものであり、更に、補強工事を専ら建物外で行うことによって耐震補強工事を促進させるものである。 The present invention provides a reinforcing body that does not collapse even in an earthquake with a seismic intensity of about 6 by arranging reinforcing walls at right angles on the two outer sides of the building corner and fixing them to existing structural materials. Furthermore, seismic reinforcement work is promoted by carrying out reinforcement work exclusively outside the building.

本発明補強体は、既存建物の隅部外側２面の土台と桁又は梁などの構造材に、外側面にＵ溝を有する取付部材を夫々対向させて固定すると共にＵ溝間に建物階高長を有する１以上の長尺中空パネル単板の端部を嵌合固定した後、中空パネル単板の内部空間にセメントグラウト材が充填されてユニットパネル補強壁によって構成される。
中空パネル単板は、断面方形の中空体を用いることもできるが、短辺部と長辺部を有し所定寸法に形成された一対の断面コ状部材を現場で嵌合して組立てるものが好ましい。 断面コ状部材は、ステンレス又はアルミなどの金属薄板で折曲げ成型されたもの或いは強化プラスチックによっても成型できる。
また、土台に固定されたＵ溝付取付部材の底部に鉄筋（網組み鉄筋）を垂設し、この鉄筋を増打ちモルタルによって布基礎側面と一体化させることによって上記の補強体構造を更に強化できる。 The reinforcing body of the present invention fixes a mounting member having a U-groove on the outer surface to the base material on the two outer corners of the existing building and a structural material such as a beam or a beam, and fixes the height of the building floor between the U-grooves. After the end portions of one or more long hollow panel single plates having a length are fitted and fixed, the interior space of the hollow panel single plate is filled with a cement grout material and configured by a unit panel reinforcing wall.
The hollow panel single plate can be a hollow body having a square cross section, but a pair of cross-section U-shaped members having a short side portion and a long side portion and having a predetermined dimension are assembled and assembled on site. preferable. The cross-sectionally U-shaped member can be formed by bending a thin metal plate such as stainless steel or aluminum, or by using reinforced plastic.
In addition, the reinforcing structure is further strengthened by suspending a reinforcing bar (mesh rebar) at the bottom of the U-grooved mounting member fixed to the base and integrating the reinforcing bar with the side of the fabric foundation using additional mortar. it can.

本発明は、Ｕ溝付取付部材の固定、パネル単板の嵌合組立て及びグラウト材注入などの全ての作業を補強建物内に立入らずに建物外で行うから生活に支障をきたすことなく施工できる上、床組みの水平剛性が保持されている家屋であれば、本発明構造を適用することによって大地震時にも建物の倒壊を防ぐことができる。 Since the present invention performs all operations such as fixing of U-grooved mounting members, panel single plate fitting assembly, and grout material injection outside the building without entering the reinforced building, construction without affecting the life In addition, if the house has the horizontal rigidity of the floor structure, the structure of the present invention can be applied to prevent the building from collapsing even during a large earthquake.
