Abstract

PROBLEM TO BE SOLVED: To provide a reinforcing method preventing a detached house or a building from collapsing by an earthquake.SOLUTION: Fixing fittings 5 of a reinforcing frame 3 with a brace are fixed by drilling holes in a column 7 and a beam 6 on an exterior wall side of an existing detached house or a building. Unevenness is formed on the surfaces of contact between the fixing fittings 5 and each of the column 7 and the beam 6 to improve adhesion performance and to prevent displacement. The reinforcing frame 3 with the fixing fittings 5 is fixed to the fixing fittings by using screws or bolts in the case of a wooden house or building. In the case of a steel frame house or building, the fixing is performed by welding or by bolts, and caulking etc. is directly applied in the holes.

Description

この発明は地震による建物倒壊防止補強工法に関するものである。The present invention relates to a reinforcement method for preventing building collapse due to an earthquake.

従来の技術の欠点は柱・梁から金具までの長さが長く、強度不足。また、筋交いの丸棒が、いかにも弱々しく、また、デザイン的にもあまり良いとはいえない。一個建て住宅または建物が、その補強筋交いを入れる事により、簡易プレハブのごとく見栄えの悪い物になってしまっていた。 The disadvantage of the conventional technology is that the length from the pillar / beam to the metal fitting is long and the strength is insufficient. In addition, the brace bar is very weak and not very good in design. A single-storied house or building has become unsightly like a simple prefab by adding its reinforcements.

梁から金具までの長さが長く、強度不足。また、筋交いの丸棒が、いかにも弱々しく、また、デザイン的にもあまり良いとはいえない。一個建て住宅が、その補強筋交いを入れる事により、簡易プレハブのごとく見栄えの悪い住宅または建物になってしまっていた。本発明はこれらの欠点を解決する為になされたものである。 The length from the beam to the metal fitting is long and the strength is insufficient. In addition, the brace bar is very weak and not very good in design. A single-family house has become a poor-looking house or building, just like a simple prefab, due to the reinforcement reinforcement. The present invention has been made to solve these drawbacks.

筋交い入り補強フレーム（３）の固定金具（５）を柱（７）・梁（６）の外壁に穴をあけ固定する。筋交い入り補強フレーム（３）と固定金具（５）を締め付け固定する。筋交い入り補強フレーム（３）は１個から数個を積み重ねる事により、柱（７）・梁（６）とのつなぎ及び補強の筋交いとなる。本発明は以上の構成からなる建物耐震補強工法である。 A fixing bracket (5) of the reinforcing frame (3) with braces is drilled and fixed to the outer walls of the columns (7) and beams (6). Tighten and fix the bracing reinforcement frame (3) and the fixing bracket (5). The reinforcing frames (3) with braces (3) are connected to the pillars (7) and beams (6) and reinforced braces by stacking one to several frames. The present invention is a building seismic reinforcement method having the above-described configuration.

発明の効果を説明すれば、固定金具（５）の柱（７）及び梁（６）への固定が簡単であり、屋外での作業であり、工事中も生活に何も影響が無く、壁等解体も無いので、短期間の工事期間で工事も出来るし、結局安価な工法と言える。従来の工法に比べ、強度的にもアップしているし、デザイン的にも、単なる補強の筋交いでは無く、建物のデザインの一部として、優れていると言える。 The effect of the invention will be explained. The fixing of the fixing bracket (5) to the column (7) and the beam (6) is simple, it is an outdoor work, and there is no influence on the life even during construction. Since there is no equal dismantling, construction can be done in a short construction period, and it can be said that it is an inexpensive construction method. Compared to conventional construction methods, it is improved in strength, and it can be said that it is excellent as a part of the design of the building, not just the reinforcement reinforcement.

The contact surfaces of the fixture (5) and the pillars (7) and beams (6) are processed to have unevenness, thereby improving the adhesion and preventing the deviation. The bracing reinforcement frame (3) and the fixing bracket (5) are fixed.
The bracing reinforcement frame (3) is connected to the pillar (7) and the beam (6) and serves as a bracing for reinforcement. The present invention is a building seismic reinforcement method having the above-described configuration.
[2] The bracing reinforcement frame (3) may be one or any number may be stacked.
[3] It is also conceivable that a metal fitting for integrally fixing the base and the foundation is integrally manufactured with the bracing reinforcement frame (3) and used as a countermeasure for hole down.
[4] A method of drilling holes in the outer wall of the pillars (7) and beams (6) in the fixing bracket (5) and fixing with screws or bolts in the case of wooden construction is also conceivable.
[5] When the column (7) / beam (6) is a steel frame, the fixing bracket (5) can be fixed to the column (7) / beam (6) by welding and bolting with a nutter.
[6] Fixing bracket (5) In order to prevent rain from penetrating into the clearance of the hole formed in the outer wall of the attachment portion, caulking or the like is directly applied to the fixing bracket (5) and the outer wall clearance portion.
[7] A rainwater prevention fitting can be attached separately from the fixing fitting (5).
[8] The present invention is a building seismic reinforcement method that can be attached to wooden and steel frames by using corresponding fixing brackets (5), and can be attached to any building in a house, building, or factory.
[9] Although the present invention is an object invented to be attached to the outside, it is a building seismic reinforcement method that can be attached even inside a building when it is not attached to the outside.
The present invention is structured as described above, and in order to construct it, a fixing metal fitting (5) is made by drilling holes in the outer walls of the columns (7) and beams (6). This is a building seismic reinforcement method in which the bracing reinforcement frame (3) and the fixing bracket (5) are fastened and fixed.
