Description
本発明は、補強方法及び補強具に関する。特に、本発明は、木造建築物の補強方法及び補強具に関する。 The present invention relates to a reinforcing method and a reinforcing tool. In particular, the present invention relates to a method for reinforcing a wooden building and a reinforcing tool.
木造建築物の補強方法として、梁又は土台等の横架材と柱とによって形成される隅角部等に金具を固定し、筋交を設ける等の補強方法が知られている。この補強方法は、地震発生等によって木造建築物に加わる水平荷重を、圧縮力が作用する筋交によって受け止めつつ、金具の固定によって隅角部の変形を抑制することによって、木造建築物を剛構造化するという考え方に基づいている。 As a reinforcement method for a wooden building, a reinforcement method is known in which a metal fitting is fixed to a corner portion or the like formed by a horizontal member such as a beam or a base and a column, and a bracing is provided. In this reinforcement method, the horizontal load applied to the wooden building due to the occurrence of an earthquake, etc. is received by the bracing that the compressive force acts on, and the deformation of the corner is suppressed by fixing the metal fitting, thereby making the wooden building a rigid structure. It is based on the idea of
特許文献１には、横架材と柱とによって形成される開口部（空間部）の四隅にコーナー金具を設け、つなぎ金具で水平及び垂直方向に緊結し、対角線上に位置するコーナー金具を筋交平鉄板で緊結することによって、剛構造の骨組み（枠組み）を形成する筋交補強金具が開示されている。 In Patent Document 1, corner metal fittings are provided at the four corners of an opening (space) formed by a horizontal member and a pillar, and are fastened horizontally and vertically with a connecting metal fitting, and corner metal fittings located on diagonal lines are A bracing reinforcement fitting that forms a rigid frame (framework) by being fastened with an alternating flat steel plate is disclosed.
特許文献１の筋交補強金具は、横架材及び柱にボルトで固定されるため、横架材及び柱等の木質材料から成る構造部材を傷める。このため、特許文献１の筋交補強金具は、構造部材とボルトとの接合部分が経年劣化し易く、横架材及び柱との接合強度が低下することがある。よって、特許文献１の筋交補強金具は、補強性能の劣化を抑制することが難しい。 Since the bracing reinforcement metal fitting of patent document 1 is fixed to a horizontal member and a pillar with a volt | bolt, the structural member which consists of wooden materials, such as a horizontal member and a column, is damaged. For this reason, as for the bracing reinforcement metal fitting of patent documents 1, the joined part of a structural member and a bolt tends to deteriorate over time, and joining strength with a horizontal member and a column may fall. Therefore, it is difficult for the brace reinforcing metal fittings of Patent Document 1 to suppress the deterioration of the reinforcing performance.
また、特許文献１の筋交補強金具は、補強性能を発揮するためには、コーナー金具、つなぎ金具及び筋交平鉄板が一組となって使用される必要がある。このため、特許文献１の筋交補強金具は、部品点数が多く重いため、建築現場での運搬作業及び取り付け作業に多くの作業工程が必要となり、多大な労力を必要とする。よって、特許文献１の筋交補強金具は、建築現場での作業工程を簡略化すると共に労力を低減することが難しい。 Moreover, in order to exhibit reinforcement performance, the bracing reinforcement metal fitting of patent document 1 needs to use a corner metal fitting, a joining metal fitting, and a bracing flat iron plate as a set. For this reason, since the bracing reinforcement metal fitting of patent document 1 has many parts and is heavy, many work processes are needed for the conveyance work and attachment work in a building site, and a lot of labor is needed. Therefore, it is difficult for the bracing reinforcement fitting of Patent Document 1 to simplify the work process at the construction site and reduce the labor.
また、特許文献１の筋交補強金具は、対角線上に位置するコーナー金具を筋交平鉄板で緊結するため、横架材と柱とによって形成される開口部を塞ぐように配置される。このため、特許文献１の筋交補強金具は、壁内に筋交が設けられる開口部に適用できるが、軒下の柱と横架材とによって形成される開口部や横架材同士によって形成される開口部等の、壁で塞がれない開口部に適用することが難しい。よって、特許文献１の筋交補強金具は、壁で塞がれない開口部が多く存在する木造建築物を十分に補強することが難しい。 In addition, the bracing reinforcing metal fitting of Patent Document 1 is arranged so as to close an opening formed by a horizontal member and a column in order to fasten a corner fitting located on a diagonal line with a bracing flat iron plate. For this reason, although the bracing reinforcement metal fitting of patent document 1 can be applied to the opening part in which a bracing is provided in a wall, it is formed by the opening part and horizontal members which are formed by the pillar under the eaves and the horizontal member. It is difficult to apply to openings that are not blocked by walls, such as openings. Therefore, it is difficult for the bracing reinforcing metal fittings of Patent Document 1 to sufficiently reinforce a wooden building having many openings that are not blocked by walls.
本発明は、上述の事情に鑑みてなされたものであり、上述のような問題点を解決することを課題の一例とする。すなわち、本発明の課題の一例は、簡単な作業で補強可能であると共に、性能劣化を抑制可能な補強方法及び補強具を提供することである。 This invention is made | formed in view of the above-mentioned situation, and makes it an example of a subject to solve the above problems. That is, an example of the subject of this invention is providing the reinforcement method and reinforcement which can be reinforced by simple operation | work and can suppress performance degradation.

［１．補強具の構成］
図１は、本発明の実施形態１に係る補強具１が取り付けられる木造建築物５０の概略図である。図２は、本発明の実施形態１に係る補強具１の構成を示す図である。図２（ａ）は、補強具１の上面図を示す。図２（ｂ）は、補強具１の側面図を示す。
[1. Reinforcement configuration]
FIG. 1 is a schematic view of a wooden building 50 to which a reinforcing tool 1 according to Embodiment 1 of the present invention is attached. FIG. 2 is a diagram illustrating a configuration of the reinforcing tool 1 according to the first embodiment of the present invention. FIG. 2A shows a top view of the reinforcing tool 1. FIG. 2 (b) shows a side view of the reinforcing tool 1.
木造建築物５０は、図１に示されるように、複数の構造部材５１を接合して構成された建築物である。木造建築物５０は、木造軸組構法に基づく構造を有する建築物であってもよい。すなわち、木造建築物５０は、木質材料から成る複数の構造部材５１をピン接合で接合して構成された建築物であってもよい。 As shown in FIG. 1, the wooden building 50 is a building configured by joining a plurality of structural members 51. The wooden building 50 may be a building having a structure based on a wooden frame construction method. That is, the wooden building 50 may be a building constructed by joining a plurality of structural members 51 made of a wood material by pin joining.
複数の構造部材５１は、木造建築物５０の骨組みを形成する。複数の構造部材５１は、柱５２と、横架材５３とを含む。横架材５３は、基礎５４の上に設置される土台５５と、梁５６とを含む。２本の柱５２と２本の横架材５３とで囲まれた空間部は、木造建築物５０の骨組みの開口部５７を形成する。すなわち、開口部５７は、複数の構造部材５１によって囲まれて形成される。開口部５７の形状は矩形であってもよい。 The plurality of structural members 51 form a framework of the wooden building 50. The plurality of structural members 51 include columns 52 and horizontal members 53. The horizontal member 53 includes a base 55 installed on the foundation 54 and a beam 56. A space surrounded by the two pillars 52 and the two horizontal members 53 forms a framework opening 57 of the wooden building 50. That is, the opening 57 is formed by being surrounded by the plurality of structural members 51. The shape of the opening 57 may be a rectangle.
補強具１は、木造建築物５０を補強する器具である。補強具１は、図１に示されるように、木造建築物５０に取り付けられることによって、木造建築物５０を補強する。補強具１は、複数の構造部材５１の表面に接着されることによって、木造建築物５０に取り付けられる。具体的には、補強具１は、その両端部が複数の構造部材５１の表面に接着されることによって、木造建築物５０に取り付けられる。この際、補強具１の両端部のみが複数の構造部材５１の表面に接着されてもよい。 The reinforcing tool 1 is a tool that reinforces the wooden building 50. The reinforcement tool 1 reinforces the wooden building 50 by being attached to the wooden building 50 as shown in FIG. The reinforcing tool 1 is attached to the wooden building 50 by being bonded to the surfaces of the plurality of structural members 51. Specifically, the reinforcing tool 1 is attached to the wooden building 50 by bonding both ends thereof to the surfaces of the plurality of structural members 51. At this time, only both ends of the reinforcing tool 1 may be bonded to the surfaces of the plurality of structural members 51.
なお、補強具１の木造建築物５０への取り付け方法については、図３を用いて後述する。木造建築物５０に取り付けられた補強具１が、木造建築物５０を補強する仕組みについては、図４を用いて後述する。 In addition, the attachment method to the wooden building 50 of the reinforcement tool 1 is later mentioned using FIG. A mechanism in which the reinforcing tool 1 attached to the wooden building 50 reinforces the wooden building 50 will be described later with reference to FIG.
補強具１は、図２（ａ）及び図２（ｂ）に示されるように、板状部材２を備える。 The reinforcing tool 1 includes a plate-like member 2 as shown in FIGS. 2 (a) and 2 (b).
板状部材２は、プラスチック複合材料から成り、板状に形成された部材である。このプラスチック複合材料は、例えば、繊維強化プラスチックである。この繊維強化プラスチックに含まれる高強度繊維材料は、例えば、炭素繊維、アラミド繊維及びガラス繊維の少なくとも１つである。好適には、板状部材２は、炭素繊維にエポキシ樹脂等を含浸させて形成された炭素繊維強化プラスチックで構成される。好適には、板状部材２は、炭素繊維の含有率が５０％以上の炭素繊維強化プラスチックで構成される。炭素繊維強化プラスチックは、金具等に比べて腐食され難い。 The plate-like member 2 is a member made of a plastic composite material and formed in a plate shape. This plastic composite material is, for example, a fiber reinforced plastic. The high-strength fiber material contained in the fiber reinforced plastic is, for example, at least one of carbon fiber, aramid fiber, and glass fiber. The plate-like member 2 is preferably made of carbon fiber reinforced plastic formed by impregnating carbon fiber with an epoxy resin or the like. Preferably, the plate-like member 2 is made of a carbon fiber reinforced plastic having a carbon fiber content of 50% or more. Carbon fiber reinforced plastic is less likely to be corroded than metal fittings.
炭素繊維強化プラスチックで構成された板状部材２は、幅５０ｍｍ、長さ９００ｍｍ及び厚さ１．２ｍｍの寸法において、１５０ｇ程度の重量しかなく、１３７．３ｋＮ（１４重量トン）の引張力に耐え得ることができる。この引張力に係る性能を、構造部材５１の一般的な材料である杉で達成するためには、板状部材２と同じ幅（５０ｍｍ）及び同じ長さ（９００ｍｍ）を有する場合、その厚さが１２０ｍｍも必要となる。すなわち、板状部材２は、炭素繊維強化プラスチックで構成されることによって、薄型化及び軽量化が可能となる。なお、板状部材２の長さとは、板状部材２の長手方向の寸法である。板状部材２の幅とは、板状部材２の長手方向と略同一な平面において長手方向に略垂直な方向の寸法である。 The plate-like member 2 made of carbon fiber reinforced plastic has a weight of about 150 g in a width of 50 mm, a length of 900 mm, and a thickness of 1.2 mm, and can withstand a tensile force of 137.3 kN (14 weight tons). Can be obtained. In order to achieve the performance related to the tensile force with cedar which is a general material of the structural member 51, the thickness is the same when the plate member 2 has the same width (50 mm) and the same length (900 mm). 120mm is also required. That is, the plate-like member 2 can be reduced in thickness and weight by being made of carbon fiber reinforced plastic. The length of the plate-like member 2 is a dimension in the longitudinal direction of the plate-like member 2. The width of the plate member 2 is a dimension in a direction substantially perpendicular to the longitudinal direction on a plane substantially the same as the longitudinal direction of the plate member 2.
板状部材２は、中央部３から両端部４までの板状部材２の大部分が、矩形の板状に形成されている。しかし、板状部材２の両端部４は、中央部３よりも大きな幅を有するように形成されている。好適には、板状部材２の両端部４は、中央部３の幅より長い辺の五角形となるように形成されてもよい。板状部材２の両端部４の各裏面は、板状部材２の構造部材５１との接着面５を構成する。すなわち、板状部材２は、接着面５の幅が中央部３の幅より大きくなるように形成されることで、板状部材２と構造部材５１との接着強さが増大する。また、接着面５には、凹凸加工等の表面処理が施されており、板状部材２と構造部材５１との接着強さを増大させている。 Most of the plate-like member 2 from the central portion 3 to both end portions 4 of the plate-like member 2 is formed in a rectangular plate shape. However, both end portions 4 of the plate-like member 2 are formed to have a larger width than the central portion 3. Preferably, both end portions 4 of the plate-like member 2 may be formed to have a pentagonal shape with a side longer than the width of the central portion 3. Each back surface of both end portions 4 of the plate-like member 2 constitutes an adhesive surface 5 with the structural member 51 of the plate-like member 2. That is, the plate-like member 2 is formed such that the width of the bonding surface 5 is larger than the width of the central portion 3, thereby increasing the bonding strength between the plate-like member 2 and the structural member 51. Further, the bonding surface 5 is subjected to surface treatment such as uneven processing, thereby increasing the bonding strength between the plate-like member 2 and the structural member 51.
板状部材２と構造部材５１との接着に使用される接着剤は、特に限定されない。板状部材２が炭素繊維強化プラスチックで構成される場合には、この接着剤として木工用の接着剤等が使用されてよい。この木工用の接着剤とは、例えば、フェノール樹脂系、α−オレフィン系、酢酸ビニル樹脂エマルジョン系等の接着剤である。 The adhesive used for bonding the plate-like member 2 and the structural member 51 is not particularly limited. When the plate-like member 2 is made of carbon fiber reinforced plastic, a woodworking adhesive or the like may be used as the adhesive. This woodworking adhesive is, for example, an adhesive such as a phenol resin, α-olefin, or vinyl acetate resin emulsion.
［２．補強方法］
図３は、本発明の実施形態１に係る補強具１の木造建築物５０への取り付け方法を示すフローチャートである。図４は、本発明の実施形態１に係る補強方法を説明するための図であって、補強具１が木造建築物５０に取り付けられた状態を示す。
[2. Reinforcement method]
FIG. 3 is a flowchart showing a method for attaching the reinforcing tool 1 to the wooden building 50 according to the first embodiment of the present invention. FIG. 4 is a view for explaining the reinforcing method according to the first embodiment of the present invention, and shows a state in which the reinforcing tool 1 is attached to the wooden building 50.
上述のように、補強具１は、木造建築物５０へ取り付けられることによって、木造建築物５０を補強する。すなわち、実施形態１に係る補強方法は、上述の補強具１を木造建築物５０に取り付けることによって、木造建築物５０を補強する方法である。補強具１の木造建築物５０への取り付け方法は、図３に示されるように、ステップＳ３０１の架渡工程と、ステップＳ３０２の接着工程とを少なくとも含む。 As described above, the reinforcing tool 1 is attached to the wooden building 50 to reinforce the wooden building 50. That is, the reinforcing method according to the first embodiment is a method of reinforcing the wooden building 50 by attaching the above-described reinforcing tool 1 to the wooden building 50. The attachment method to the wooden building 50 of the reinforcement tool 1 includes at least a spanning process in step S301 and an adhesion process in step S302, as shown in FIG.
ステップＳ３０１の架渡工程は、補強具１の板状部材２を、複数の構造部材５１に囲まれて形成された開口部５７に架け渡す工程である。この工程において、板状部材２は、開口部５７を形成する複数の構造部材５１のうちで互いに対向する一対の構造部材５１から、開口部５７の中央側に離隔し、且つ、一対の構造部材５１に沿うように、架け渡される。 The spanning step of step S301 is a step of spanning the plate-like member 2 of the reinforcing tool 1 to the opening 57 formed by being surrounded by the plurality of structural members 51. In this step, the plate-like member 2 is separated from the pair of structural members 51 facing each other among the plurality of structural members 51 forming the opening 57 to the center side of the opening 57, and the pair of structural members It is bridged along 51.
具体的には、図４において、開口部５７を形成する複数の構造部材５１は、２本の柱５２及び２本の横架材５３として示されている。また、開口部５７を形成する複数の構造部材５１のうちで互いに対向する一対の構造部材５１は、２本の柱５２又は２本の横架材５３の何れかである。図４の例では、開口部５７を形成する複数の構造部材５１のうちで互いに対向する一対の構造部材５１は、２本の横架材５３として示されている。この場合、板状部材２は、この一対の構造部材５１である２本の横架材５３の一方から所定の間隔Ｄだけ開口部５７の中央側に離隔するように、開口部５７に架け渡される。加えて、板状部材２は、この一対の構造部材５１である２本の横架材５３の一方に沿うように、開口部５７に架け渡される。間隔Ｄの寸法は、特に限定されないが、２本の横架材５３の中間に板状部材２が位置するような寸法を避ける方が好ましい。好適には、間隔Ｄの寸法は、２本の横架材５３の一方の近傍に板状部材２が位置するような寸法であってよい。 Specifically, in FIG. 4, the plurality of structural members 51 forming the opening 57 are shown as two columns 52 and two horizontal members 53. The pair of structural members 51 that face each other among the plurality of structural members 51 that form the opening 57 is either the two columns 52 or the two horizontal members 53. In the example of FIG. 4, the pair of structural members 51 that are opposed to each other among the plurality of structural members 51 that form the opening 57 are shown as two horizontal members 53. In this case, the plate-like member 2 is stretched over the opening 57 so as to be separated from one of the two horizontal members 53 as the pair of structural members 51 toward the center of the opening 57 by a predetermined distance D. It is. In addition, the plate-like member 2 is stretched over the opening 57 so as to be along one of the two horizontal members 53 that are the pair of structural members 51.

ステップＳ３０２の接着工程は、ステップＳ３０１の架渡工程によって架け渡された板状部材２が定着するよう、板状部材２の両端部４を、開口部５７を形成する複数の構造部材５１に接着する工程である。この工程において、板状部材２は、開口部５７を形成する複数の構造部材５１のうちで、板状部材２を沿わせた上述の一対の構造部材５１とは異なる他の一対の構造部材５１に対して接着される。 In the bonding process in step S302, both end portions 4 of the plate-like member 2 are bonded to the plurality of structural members 51 forming the openings 57 so that the plate-like member 2 bridged in the spanning process in step S301 is fixed. It is a process to do. In this step, the plate-like member 2 is a pair of other structural members 51 different from the above-described pair of structural members 51 along the plate-like member 2 among the plurality of structural members 51 forming the opening 57. Is adhered to.
具体的には、図４において、板状部材２を沿わせた上述の一対の構造部材５１は、２本の横架材５３として示されている。また、上述の一対の構造部材５１とは異なる他の一対の構造部材５１は、２本の柱５２として示されている。この場合、板状部材２の両端部４は、上述の他の一対の構造部材５１である２本の柱５２に対して、接着される。 Specifically, in FIG. 4, the above-described pair of structural members 51 along the plate-like member 2 are shown as two horizontal members 53. Further, another pair of structural members 51 different from the above-described pair of structural members 51 is shown as two pillars 52. In this case, both end portions 4 of the plate-like member 2 are bonded to the two columns 52 which are the other pair of structural members 51 described above.
この際、板状部材２の両端部４は、板状部材２が非緊張状態で定着するよう、２本の柱５２に対して接着されてもよい。板状部材２が非緊張状態で定着するとは、板状部材２に予め緊張力を与えない状態、すなわち、板状部材２にプレストレスを与えない状態で、板状部材２が定着することである。言い換えると、板状部材２が非緊張状態で定着するとは、板状部材２が自然長のままで定着することである。 At this time, both end portions 4 of the plate-like member 2 may be bonded to the two columns 52 so that the plate-like member 2 is fixed in a non-tensioned state. When the plate-like member 2 is fixed in a non-tensioned state, the plate-like member 2 is fixed in a state where no tension is applied to the plate-like member 2 in advance, that is, in a state where no pre-stress is applied to the plate-like member 2. is there. In other words, the fact that the plate-like member 2 is fixed in a non-tensioned state means that the plate-like member 2 is fixed with its natural length.
なお、ステップＳ３０１の架渡工程には、板状部材２を開口部５７に架け渡す前の工程として、架け渡す対象の開口部５７まで板状部材２を運搬する運搬工程と、運搬工程によって運搬された板状部材２の両端部４における接着面５に、接着剤を塗布する塗布工程とが含まれてもよい。また、ステップＳ３０１の架渡工程には、運搬工程と塗布工程との間に行われ、運搬工程によって運搬された板状部材２の長さを、開口部５７の形状に合わせて調整する調整工程が含まれてもよい。調整工程では、板状部材２の中央部３を切断して得られた複数の板状部材２のそれぞれの切断部分の表面の一部を、上述の一対の構造部材５１とは異なる他の一対の構造部材５１同士の距離に応じて重ね合せる。そして、調整工程では、この複数の板状部材２の重なり合った面に接着剤を塗布して硬化させることによって、板状部材２の長さを調整する。 In addition, in the spanning process of step S301, as the process before bridging the plate-like member 2 to the opening 57, the carrying process of carrying the plate-like member 2 to the opening 57 to be bridged and the carrying process are carried. An application step of applying an adhesive may be included in the adhesive surfaces 5 at both end portions 4 of the plate-like member 2 that has been made. In addition, the spanning process in step S301 is an adjustment process that is performed between the transporting process and the coating process, and adjusts the length of the plate-like member 2 transported by the transporting process according to the shape of the opening 57. May be included. In the adjustment step, a part of the surface of each cut portion of the plurality of plate-like members 2 obtained by cutting the central portion 3 of the plate-like member 2 is replaced with another pair different from the pair of structural members 51 described above. Are overlapped according to the distance between the structural members 51. In the adjustment step, the length of the plate-like member 2 is adjusted by applying an adhesive to the overlapping surfaces of the plurality of plate-like members 2 and curing the adhesive.
また、ステップＳ３０２の接着工程には、接着剤が硬化するまで、仮留め用のビスを用いて板状部材２の両端部４を構造部材５１に仮留めする仮留め工程と、接着剤の硬化後に、仮留め用のビスを除去する除去工程とが含まれてもよい。 In addition, in the bonding process of step S302, a temporary fixing process in which both end portions 4 of the plate-like member 2 are temporarily fixed to the structural member 51 using a temporary fixing screw until the adhesive is cured, and the adhesive is cured. A removal step for removing the temporary fixing screws may be included later.
ここで、地震発生等によって木造建築物５０に水平荷重が加わると、２本の柱５２が水平方向に傾いて隅角部５８が変形し、矩形状の開口部５７が潰れるように変形しようとする。このとき、一方の柱５２には圧縮力が作用し、他方の柱５２には引張力が作用する。柱５２に作用する引張力は、柱５２を下方の横架材５３から引き抜こうとする力として作用すると共に、柱５２の上方の横架材５３を引き上げる力として作用する。このような現象が地震発生時の横揺れで繰り返されることにより、木造建築物５０では、開口部５７の隅角部５８が大きく変形して柱５２と横架材５３との接合が外れ、やがて倒壊することがある。 Here, when a horizontal load is applied to the wooden building 50 due to the occurrence of an earthquake or the like, the two columns 52 are inclined in the horizontal direction, the corner portion 58 is deformed, and the rectangular opening portion 57 is crushed. To do. At this time, a compressive force acts on one column 52 and a tensile force acts on the other column 52. The tensile force acting on the column 52 acts as a force for pulling out the column 52 from the lower horizontal member 53 and also acts as a force for pulling up the horizontal member 53 above the column 52. By repeating such a phenomenon by the rolling at the time of the earthquake occurrence, in the wooden building 50, the corner portion 58 of the opening 57 is greatly deformed and the joining of the column 52 and the horizontal member 53 is released. May collapse.
図４のように補強具１が取り付けられた木造建築物５０では、水平荷重によって２本の柱５２が傾き隅角部５８が変形しようとすると、補強具１が緊張し、補強具１には引張力が作用する。補強具１が取り付けられた木造建築物５０では、補強具１が、作用する引張力に耐えることによって水平荷重を受け止め、隅角部５８の変形を抑制することができる。それにより、補強具１が取り付けられた木造建築物５０は、地震発生等によって水平荷重が加わっても、柱５２と横架材５３との接合が外れ難くなり、倒壊し難くなるため、耐震性が向上する。よって、補強具１を図３に示された取り付け方法で図４のように木造建築物５０に取り付けることは、木造建築物５０の補強方法として有効である。 In the wooden building 50 to which the reinforcing tool 1 is attached as shown in FIG. 4, when the two pillars 52 are inclined and the corner portion 58 is deformed by a horizontal load, the reinforcing tool 1 is tensioned, A tensile force acts. In the wooden building 50 to which the reinforcing tool 1 is attached, the reinforcing tool 1 can receive the horizontal load by withstanding the acting tensile force and can suppress the deformation of the corner portion 58. As a result, the wooden building 50 to which the reinforcing tool 1 is attached has a seismic resistance because it is difficult for the column 52 and the horizontal member 53 to be detached from each other even if a horizontal load is applied due to the occurrence of an earthquake or the like, and it is difficult to collapse. Will improve. Therefore, attaching the reinforcing tool 1 to the wooden building 50 as shown in FIG. 4 by the attaching method shown in FIG. 3 is effective as a reinforcing method for the wooden building 50.
なお、補強具１が非緊張状態で定着するように取り付けられた木造建築物５０であっても、水平荷重によって隅角部５８が変形しようとする際には、補強具１が緊張して水平荷重を受け止めることができるため、必要な耐震性が確保される。よって、補強具１を非緊張状態で定着するように木造建築物５０に取り付けることも、木造建築物５０の補強方法として有効である。 Even if the wooden building 50 is attached so that the reinforcing tool 1 is fixed in a non-tensioned state, when the corner portion 58 is deformed by a horizontal load, the reinforcing tool 1 is tensioned and horizontal. The necessary seismic resistance is ensured because the load can be received. Therefore, attaching the reinforcing tool 1 to the wooden building 50 so as to be fixed in a non-tensioned state is also effective as a reinforcing method of the wooden building 50.
