Description

本考案は、従来の在来構法による木造建物の壁の補強に較べ、極めて高い補強強度を得ることのできる木造建物の壁補強フレームに関する。   The present invention relates to a wall reinforcement frame of a wooden building that can obtain extremely high reinforcement strength as compared with the conventional wall reinforcement of a wooden building.

木造建物の在来構法においては、コンクリート基礎上に取付け固定された木製の土台に柱を立て、その上に軒桁や胴差し等の梁材を横架して囲まれた枠内に筋交いを斜め対角状に取付けると共に、筋交いの端部と土台や柱及び梁材との接合部には金属製プレートを打ち付けて壁を補強するやり方が一般的である。この補強するやり方は、現場において大工の手作業で行うと共に、建築物の全体に亘って行うためには多大の時間と労力を要するほか、金属製プレートの付け忘れや手抜きが行われやすく、地震や台風による木造建物の強度不足が指摘される。   In the conventional construction method of wooden buildings, a pillar is set up on a wooden base fixed on a concrete foundation, and a brace is placed in a frame surrounded by beam members such as eaves girder and torso. A general method is to attach diagonally diagonally and reinforce the wall by hitting a metal plate at the joint between the end of the brace and the base, column, and beam. This method of reinforcement is done manually by carpenters at the site, and it takes a lot of time and labor to carry out the entire building, and it is easy to forget to attach or cut out metal plates. It is pointed out that wooden buildings are not strong enough due to typhoons.

現場での大工の手作業によらず工場等で一体化を可能とするものとしては、木造建物における木造軸組用壁フレーム（特許文献１参照）や、構造用パネル（特許文献２参照）が開示されている。
又、一対の木製部材の各々に、所定方向に延びた溝を形成し、該溝に前記木製部材の双方に亘って延びるように棒状部材を埋設すると共に、接着剤を前記溝に充填して接合するようにした木製部材の接合方法（特許文献３参照）が開示されている。 For example, a wooden frame wall frame in a wooden building (see Patent Document 1) or a structural panel (see Patent Document 2) can be integrated in a factory or the like regardless of carpenter's manual work on site. It is disclosed.
Further, a groove extending in a predetermined direction is formed in each of the pair of wooden members, and a rod-shaped member is embedded in the groove so as to extend over both of the wooden members, and an adhesive is filled in the groove. A method for joining wooden members to be joined (see Patent Document 3) is disclosed.

上記特許文献１に記載される木造建物における木造軸組用壁フレームは、二本の柱の間に間柱と横桟を縦横に交差させ、二本の筋交いを対角状に斜めに交差させて組み付け、片面上下に位置決めボードと、両面に複数の横板を貼設して柱と共に一体化したものであり、新築の場合は良いが、既存の建物のように立設された柱と柱の間に装着して壁の補強を図るには適用し難い問題点があり、補強は従来の筋交い方式である。特許文献２に記載される構造用パネルは、複数の縦芯材と横芯材で組まれた枠体の少なくとも片面に面材を設けたパネル本体どうしを互いに接合して建物の構造体を構成する構造用パネルであって、前記パネル本体どうしの接合端面に、だぼを介して相互に位置決めするためのだぼ穴を間隔をおいて複数設けたものであり、建物の壁補強用として構成されるものではない。又、特許文献３に記載される木製部材の接合方法は、接合すべき一対の木製部材の各接端部を凹凸加工（ほぞ加工）して接合したり、或いは接合すべき一対の木製部材の双方に亘って添接された接合金物と各木製部材とを貫通ボルト等でねじ締結することによって接合したりすることによる接合強度的な不都合や加工上の不都合を解決しようとするものであり、建物の壁補強を目的としたフレームを構成するものではない。   The wooden frame wall frame in the wooden building described in the above-mentioned Patent Document 1 crosses a vertical column and a horizontal beam vertically and horizontally between two columns, and diagonally intersects the two braces diagonally. Assembly, positioning board on top and bottom on one side, and multiple horizontal plates on both sides are integrated with pillars, and in the case of a new construction, it is good for pillars and pillars erected like existing buildings There is a problem that is difficult to apply in order to reinforce the wall by attaching it between them, and the reinforcement is a conventional bracing method. The structural panel described in Patent Document 2 constitutes a building structure by joining together panel bodies provided with face materials on at least one side of a frame formed by a plurality of vertical core members and horizontal core members. A structural panel, wherein a plurality of dowel holes are provided on the joint end surfaces of the panel bodies to be positioned with respect to each other via a dowel, and are configured to reinforce a building wall Is not to be done. Moreover, the joining method of the wooden member described in patent document 3 joins each contact edge part of a pair of wooden member which should be joined by uneven | corrugated processing (tenon processing), or a pair of wooden member which should be joined. It is intended to solve the inconvenience in terms of joint strength and processing due to joining by joining the metal fittings attached to both sides and each wooden member by screwing with a through bolt or the like, It does not constitute a frame intended to reinforce the walls of the building.

本考案は、建物の柱と土台及び軒桁や胴差し等の梁材とで囲まれる枠内に嵌め込んで固定することにより従来の在来構法による木造建物の壁補強に較べ、極めて高い補強強度が得られ、且つ既存建物の壁の補強（リフォーム）にも適用し得る建物の壁補強フレーム及び壁の補強方法を提供することを目的とするもので、該目的を達成することを課題とする。   The present invention is extremely high compared to the conventional wall reinforcement of wooden buildings by fitting and fixing in a frame surrounded by pillars and foundations of the building and beam materials such as eaves girder and torso. An object of the present invention is to provide a wall reinforcing frame and a wall reinforcing method for a building that can provide strength and can be applied to wall reinforcement (reformation) of an existing building.

更に、縦角柱材１，１Ａ、横角柱材２，２Ａの一辺がそれぞれ６０ｍｍ，９０ｍｍの正四角形でスギ集成材（ＳＧ）の場合の壁補強フレームを前記試験例１と同様にして試験した結果は、図１５〜図１８に示すとおりであった。なお、壁補強フレーム（試験品）の試験結果は、ＳＧ６０−２０−１が図１５で一辺が６０ｍｍの角柱材，直径が２０ｍｍの駄柄材の場合、ＳＧ６０−３０−１が図１６で一辺が６０ｍｍの角柱材，直径が２０ｍｍの駄柄材の場合、ＳＧ９０−２０−１が図１７で一辺が９０ｍｍの角柱材，直径が２０ｍｍの駄柄材の場合、ＳＧ９０−３０−１が図１８で一辺が９０ｍｍの角柱材，直径が３０ｍｍの駄柄材の場合であり、左右の縦角柱材１，１と上下の横角柱材２，２接合部の駄柄材は一本である。   Furthermore, the result of testing the wall reinforcing frame in the case of a square of 60 mm and 90 mm on each side of the vertical prisms 1 and 1A and the horizontal prisms 2 and 2A in the case of cedar laminated timber (SG) in the same manner as in Test Example 1. Was as shown in FIGS. In addition, the test result of the wall reinforcing frame (test product) is that SG60-20-1 is a prismatic material having a side of 60 mm in FIG. 15 and a blank material having a diameter of 20 mm, and SG60-30-1 is a side in FIG. SG90-20-1 is a prismatic material with a diameter of 60 mm and SG90-30-1 is FIG. 18 when SG90-20-1 is a prismatic material with a side of 90 mm and a waste material with a diameter of 20 mm. This is the case of a prismatic material with a side of 90 mm and a waste material with a diameter of 30 mm, and there is only one waste material at the junction of the left and right vertical prism members 1, 1 and the upper and lower horizontal prism materials 2, 2.

上記図１５〜図１８により得られる最大荷重Ｐｍａｘ（ＫＮ）は表５に示すとおりで、図１５〜図１８に基いて算出される完全弾塑性モデルによる降伏耐力（ＫＮ）等の評価項目の数値は表６に示すとおりである。   The maximum load Pmax (KN) obtained from FIGS. 15 to 18 is as shown in Table 5, and numerical values of evaluation items such as yield strength (KN) based on the complete elastic-plastic model calculated based on FIGS. Is as shown in Table 6.

上記試験の評価は、建築基準法施工規則第八条の三の規定に係わる評価方法に基いて算出されたもので、降伏耐力Ｐｙの値と、終局耐力ＰＵをＤｓ＝１／√（２μ−１）で除し、０．２を乗じた値、最大耐力（荷重）Ｐｍａｘの２／３の値、特定変形時の耐力（無載荷式の場合は見掛けのせん断変形角１／１２０ｒａｄ時の耐力）の値を算出することになっており、これらの値の最小値を求めると共に、これらの値から短期許容せん断耐力を求め、壁倍率を算出したものである。   The evaluation of the above test was calculated based on the evaluation method according to the provisions of Article 8-3 of the Building Standard Law Construction Rules. The value of the yield strength Py and the ultimate strength PU are expressed as Ds = 1 / √ (2μ− 1) divided by 0.2, 2/3 of maximum proof stress (load) Pmax, proof stress at specific deformation (in the case of no-load type, proof stress at apparent shear deformation angle 1/120 rad ), The minimum value of these values is obtained, the short-term allowable shear strength is obtained from these values, and the wall magnification is calculated.

従来の施行令第４６条によれば、厚さ３ｃｍ以上で幅９ｃｍ以上の木材の筋交いを入れた軸組みの場合の壁倍率が１．５、厚さ４．５ｃｍ以上で幅９ｃｍ以上の木材の筋交いを入れた軸組みの場合の壁倍率が２．０となっており、現在の壁倍率評価とは多少異なる点もあるが、上記試験結果からして本発明によればかなりの耐力（補強）効果があることがわかり、更に縦角柱材１Ａと横角柱材２Ａを多くして格子数を増やしたり、駄柄材を鉄筋にしたりすれば更なる壁倍率の向上が図られる。   According to Article 46 of the conventional enforcement order, the wall magnification is 1.5, the wall magnification is more than 4.5cm and the width is more than 9cm in the case of the frame assembly with the bracing of the wood that is more than 3cm and the width is more than 9cm. The wall magnification in the case of a shaft assembly including the bracing of 2.0 is 2.0, and there are some differences from the current wall magnification evaluation. However, according to the present invention, considerable strength ( It can be seen that there is an effect of reinforcement, and if the number of grids is increased by increasing the length of the vertical columnar material 1A and the horizontal rectangular columnar material 2A or the waste material is made of reinforcing bars, the wall magnification can be further improved.
