Description

本発明は、例えば、れんが、コンクリートブロック、石などが組み上げられて形成されている組積造構造物を補強するための補強構造に関するものである。   The present invention relates to a reinforcing structure for reinforcing a masonry structure formed by assembling bricks, concrete blocks, stones, and the like.

近年、近代建築の歴史的価値が認識されており、これらの建築物を文化遺産として保存することが求められている。これらの建築物の多くはれんが造であり、その大半は補強工事が必要である。既往の補強技術としては、鉄筋コンクリート造（ＲＣ造）や鉄骨造（Ｓ造）の躯体を建築物に増築したり、ＲＣ造やＳ造をれんが壁と一体化したりするものがある。   In recent years, the historical value of modern architecture has been recognized, and it is required to preserve these buildings as cultural heritage. Many of these buildings are made of brick, and most of them require reinforcement work. As the existing reinforcement technology, there is a method in which a reinforced concrete structure (RC structure) or a steel frame structure (S structure) is added to a building, or an RC structure or S structure is integrated with a brick wall.

しかしながら、これらの補強技術を用いた補強構造では、補強することにより建築物の外観や内観を著しく毀損させてしまう。また、れんがの耐久性や美観にも悪影響を与えてしまうという問題点を有している。そのため、建築物を良好な状態で保存することが困難であった。   However, in the reinforcement structure using these reinforcement techniques, the exterior and interior appearance of the building are significantly damaged by reinforcement. In addition, there is a problem that the durability and aesthetics of the brick are adversely affected. Therefore, it was difficult to preserve the building in a good state.

外観に影響を及ぼさない補強構造としては、例えば、特許文献１に示すようなものがある。この特許文献１の技術では、壁体の上部に鉄骨梁を水平に設けると共に壁体の下部に地中梁を設け、この鉄骨梁と地中梁との間の壁体の内部を鉛直に貫通する貫通孔を複数形成し、それぞれの貫通孔にＰＣ鋼棒を配設している。   As a reinforcing structure that does not affect the appearance, for example, there is a structure as shown in Patent Document 1. In the technique of this Patent Document 1, a steel beam is horizontally provided at the upper part of the wall body and an underground beam is provided at the lower part of the wall body, and the interior of the wall body between the steel beam and the underground beam is vertically penetrated. A plurality of through holes are formed, and a PC steel rod is disposed in each through hole.

また、特許文献２には、れんが壁の部分的な損傷を補修するものが開示されている。具体的には、れんが壁体の壁面に水平方向の亀裂が生じてしまった場合に、れんが壁体の亀裂の上側および下側の部分から亀裂面に向けて斜めに孔を形成し、この孔内にエポキシ樹脂を充填すると共に鉄筋等を埋め込むものが開示されている。また、れんが壁体の壁面に垂直方向の亀裂が生じてしまった場合には、れんが壁体の亀裂の左側および右側の部分から亀裂面に向けて斜めに孔を形成し、この孔内にエポキシ樹脂を充填すると共に鉄筋等を埋め込むことが開示されている。   Patent Document 2 discloses a technique for repairing partial damage to a brick wall. Specifically, when a horizontal crack has occurred in the wall of a brick wall, a hole is formed obliquely from the upper and lower parts of the brick wall toward the crack surface. An article in which an epoxy resin is filled and a reinforcing bar or the like is embedded is disclosed. In addition, when a crack in the vertical direction has occurred on the wall of the brick wall, holes are formed diagonally from the left and right sides of the brick wall toward the crack surface, and an epoxy is formed in the hole. It is disclosed that a resin is filled and a reinforcing bar or the like is embedded.

しかしながら、特許文献１の技術では、壁体の上部から下部に亘って鉛直に貫通孔を形成する必要があるが、この貫通孔を形成する作業が困難であった。また、壁体の上部に鉄骨梁を設けたり貫通孔を形成するためには、壁体の上部に作業スペースが必要となる。しかしながら、壁体の上部に屋根等がある場合には、この屋根を解体し、補強工事後に屋根を復旧しなければならない。そのため、工事が長期化し、工事費用が高くなるという問題があった。さらに、特許文献２の技術では、れんが壁体の部分的な損傷を補修することはできるが、れんが壁体の全体を補強し、耐震性を向上させることはできない。   However, in the technique of Patent Document 1, it is necessary to form a through hole vertically from the upper part to the lower part of the wall body, but it is difficult to form the through hole. In order to provide a steel beam or to form a through hole in the upper part of the wall body, a work space is required in the upper part of the wall body. However, when there is a roof or the like on the upper part of the wall body, it is necessary to dismantle the roof and restore the roof after reinforcement work. For this reason, there is a problem that the construction is prolonged and the construction cost becomes high. Furthermore, although the technique of patent document 2 can repair the partial damage of a brick wall body, it cannot reinforce the whole brick wall body and can improve earthquake resistance.

本発明は、上記実情に鑑みてなされたものであり、組積造構造物の外観または内観を毀損させることがなく、壁体の全体を効果的に補強することができ、簡単な工事で壁体の補強を行なうことができる組積造構造物の補強構造を提供する。   The present invention has been made in view of the above circumstances, and can effectively reinforce the entire wall body without damaging the external appearance or interior view of the masonry structure.

Note that the present invention is not limited to these embodiments. Moreover, in the following embodiments, a brick wall reinforcing structure formed by building bricks will be described as an example of a masonry building.

図１は本発明の実施例１に係る組積造構造物の補強構造を用いたれんが壁の正面図、図２は図１のＡ−Ａ線で切断した状態の側部断面図、図３は図１のＢ−Ｂ線で切断した状態の上側断面図を示す。   1 is a front view of a brick wall using a reinforcement structure for a masonry structure according to Embodiment 1 of the present invention, FIG. 2 is a side cross-sectional view taken along line AA of FIG. FIG. 3 shows an upper cross-sectional view taken along the line BB in FIG.

れんが壁１は、複数のれんが２を垂直方向または水平方向に組積して形成されている。このれんが壁１は、建造物の外側の面を構成する外壁面１ａと、その内側の面を構成する内壁面１ｂとを備えており、これらの外壁面１ａおよび内壁面１ｂは、ほぼ垂直な平面（縦壁面）を構成している。   The brick wall 1 is formed by stacking a plurality of bricks 2 in the vertical direction or the horizontal direction. The brick wall 1 includes an outer wall surface 1a constituting an outer surface of a building and an inner wall surface 1b constituting an inner surface thereof. The outer wall surface 1a and the inner wall surface 1b are substantially vertical. A plane (vertical wall surface) is formed.

この内壁面１ｂには、複数の挿入口４ａ，４ｂが形成されている。この複数の挿入口４ａの形状は丸形形状に形成されている。この挿入口４ａの中心は、図１に示すように、内壁面１ｂの鉛直方向に間隔を置いて直線上に配置されており、列５ａを成している。同様に、複数の挿入口４ｂの形状は丸形形状に形成され、この挿入口４ｂの中心が内壁面１ｂの鉛直方向に間隔を置いて直線上に配置されており、列５ａとは別の列５ｂを成している。この列５ａおよび列５ｂは、互いに隣り合っており、内壁面１ｂを正面から見て（図１参照）水平方向に間隔を置いて平行に配置されている。なお、この挿入口４ａ，４ｂは同じ大きさに形成されている。   A plurality of insertion openings 4a and 4b are formed in the inner wall surface 1b. The plurality of insertion openings 4a are formed in a round shape. As shown in FIG. 1, the centers of the insertion openings 4a are arranged on a straight line at intervals in the vertical direction of the inner wall surface 1b, forming a row 5a. Similarly, the plurality of insertion openings 4b are formed in a round shape, and the centers of the insertion openings 4b are arranged on a straight line at intervals in the vertical direction of the inner wall surface 1b. Column 5b is formed. The row 5a and the row 5b are adjacent to each other, and are arranged in parallel at intervals in the horizontal direction when the inner wall surface 1b is viewed from the front (see FIG. 1). The insertion ports 4a and 4b are formed in the same size.

れんが壁１には、図２に示すように、複数の挿入口４ａから上方向挿入孔３ａが形成されている。この上方向挿入孔３ａは、図１および図２に示すように、列５ａに沿ってれんが壁１の内部へ斜め上方向に向けて形成されている。同様に、複数の挿入口４ｂから下方向挿入孔３ｂが形成されており、この下方向挿入孔３ｂは、列５ｂに沿ってれんが壁１の内部へ斜め下方向に向けて形成されている。   As shown in FIG. 2, the brick wall 1 is formed with an upward insertion hole 3a from a plurality of insertion openings 4a. As shown in FIGS. 1 and 2, the upward insertion hole 3 a is formed in a diagonally upward direction along the row 5 a into the brick wall 1. Similarly, a downward insertion hole 3b is formed from the plurality of insertion ports 4b, and the downward insertion hole 3b is formed obliquely downward into the brick wall 1 along the row 5b.

この上方向挿入孔３ａと下方向挿入孔３ｂとは、それぞれ交差することがない、ねじれの関係に配置されている。詳細には、図２に示すように、内壁面１ｂと直交する略垂直な断面であって、列５ｂの長手方向に沿って切断した断面かられんが壁１を見た状態で、互いに隣り合う上方向挿入孔３ａ（図２において点線で示されている）と下方向挿入孔３ｂ（図２において実線で示されている）とが図２の断面上において少なくとも１点で交差して見えるようになっている。   The upper insertion hole 3a and the lower insertion hole 3b are arranged in a twisted relationship so as not to intersect each other. Specifically, as shown in FIG. 2, the cross-sections are substantially perpendicular to the inner wall surface 1b and are adjacent to each other in a state where the brick wall 1 is viewed from the cross-section cut along the longitudinal direction of the row 5b. The direction insertion hole 3a (shown by a dotted line in FIG. 2) and the downward insertion hole 3b (shown by a solid line in FIG. 2) appear to intersect at least one point on the cross section of FIG. It has become.

これらの挿入孔３ａ，３ｂは、組積された複数のれんが２に亘ってそれぞれ形成されている。後述する補強材が挿入孔３ａ，３ｂに挿入されると、この補強材は複数のれんが２を縫合するようになる。また、これらの挿入孔３ａ，３ｂは、外壁面１ａまで達しておらず、外壁面１ａの外側から見てれんが壁１の外観をそのまま維持した状態になっている。   These insertion holes 3a and 3b are respectively formed over a plurality of bricks 2 stacked together. When a reinforcing material to be described later is inserted into the insertion holes 3a, 3b, the reinforcing material comes to sew a plurality of bricks 2. Further, these insertion holes 3a and 3b do not reach the outer wall surface 1a, but maintain the appearance of the brick wall 1 as it is when viewed from the outside of the outer wall surface 1a.

図４は下方向挿入孔の長さと挿入口の縦方向の間隔との関係の概要を示す。互いに隣り合う挿入口４ｂ同士の縦方向の間隔６ｂは、図４に示すように、下方向挿入孔３ｂの長さ７ｂを内壁面１ｂ上に垂直に投影したときの長さ８ｂよりも小さくなるように挿入口４ｂが配置されている。なお、この長さ８ｂは、下方向挿入孔３ｂと内壁面１ｂとの傾斜角度９ｂによっても変化することになる。そのため、間隔６ｂは、挿入口４ｂの位置と、下方向挿入孔３ｂの長さ７ｂと、傾斜角度９ｂとを全て考慮することにより構成されている。なお、互いに隣り合う挿入口４ａ同士の縦方向の間隔６ａ（図１参照）についても挿入口４ｂと同様に構成されており、挿入口４ａの位置と、上方向挿入孔３ａの長さ７ａと、傾斜角度９ａとによって決定されている。   FIG. 4 shows an outline of the relationship between the length of the downward insertion hole and the vertical interval of the insertion opening. As shown in FIG. 4, the vertical interval 6b between the insertion ports 4b adjacent to each other is smaller than the length 8b when the length 7b of the lower insertion hole 3b is vertically projected onto the inner wall surface 1b. Thus, the insertion port 4b is arranged. This length 8b also changes depending on the inclination angle 9b between the downward insertion hole 3b and the inner wall surface 1b. Therefore, the interval 6b is configured by considering all of the position of the insertion port 4b, the length 7b of the downward insertion hole 3b, and the inclination angle 9b. The vertical interval 6a (see FIG. 1) between the adjacent insertion ports 4a is also configured in the same manner as the insertion port 4b, and the position of the insertion port 4a and the length 7a of the upper insertion hole 3a And the inclination angle 9a.

これらの上方向挿入孔３ａおよび下方向挿入孔３ｂには、補強材１３が挿入され、その後に、挿入孔３ａ，３ｂと補強材１３との間に無収縮モルタルまたはエポキシ樹脂が注入される。この無収縮モルタルまたはエポキシ樹脂は補強材１３を挿入孔３ａ，３ｂに定着させており、この無収縮モルタル等を介して補強材１３と挿入孔３ａ，３ｂ（れんが壁１）との間で力の伝達が行なわれる。   The reinforcing material 13 is inserted into the upward insertion hole 3 a and the downward insertion hole 3 b, and then non-shrink mortar or epoxy resin is injected between the insertion holes 3 a and 3 b and the reinforcing material 13. This non-shrink mortar or epoxy resin fixes the reinforcing material 13 to the insertion holes 3a and 3b. A force is applied between the reinforcing material 13 and the insertion holes 3a and 3b (brick wall 1) via the non-shrink mortar. Is transmitted.

補強材１３は、例えば、鉄筋、ＰＣ鋼棒、ＦＲＰロッドまたはワイヤーなどの引張強度を有する部材が使用されている。また、この補強材１３は、その形状が、例えば、丸棒形状であって、その円周面上に節を有しているものや、長手方向の端部に定着部（ふくらみや定着板など）を有するもの、例えば、ネジふし鉄筋とナット、ＰＣ鋼棒とナット等の補強材を使用することもできる。また、端部に定着部を形成した鉄筋、端部に定着板を接合した鉄筋などもしようすることもできる。   As the reinforcing material 13, for example, a member having tensile strength such as a reinforcing bar, a PC steel rod, an FRP rod, or a wire is used. The reinforcing member 13 has a round bar shape, for example, and has a node on its circumferential surface, or a fixing portion (bulge, fixing plate, etc.) at the end in the longitudinal direction. ), For example, a reinforcing material such as a threaded reinforcing bar and nut, a PC steel rod and nut, or the like can also be used. Further, a reinforcing bar in which a fixing part is formed at the end, a reinforcing bar in which a fixing plate is joined to the end, and the like can be used.

なお、補強材１３は、その全長が挿入孔３ａ，３ｂの中に挿入されるようになっていてもよい。また、補強材１３の端部が内壁面１ｂから突出するようにしてもよい。   The full length of the reinforcing member 13 may be inserted into the insertion holes 3a and 3b. Moreover, you may make it the edge part of the reinforcing material 13 protrude from the inner wall face 1b.

この構造によれば、れんが壁１を内壁面１ｂと直交する略水平な断面で見た状態（図３に示す断面の状態）で、どの断面を取ってもその断面上に補強材１３が含まれるようになる。これにより、れんが壁１の内壁面１ｂと略水平な断面に生じるせん断応力および曲げ応力に対して、補強材１３がこのせん断応力および曲げ応力に抗し、れんが壁１の強度をより高めることができる。また、上方向挿入孔３ａと下方向挿入孔３ｂとが互いに干渉することなく、限られたスペースの中で補強材１３を有効に配置することができる。さらに、れんが壁１の壁部を多く残した状態で、れんが壁１を効果的に補強することができる。   According to this structure, the reinforcing material 13 is included on any cross section when the brick wall 1 is viewed in a substantially horizontal cross section orthogonal to the inner wall surface 1b (the cross section shown in FIG. 3). It comes to be. Thereby, the reinforcing material 13 resists the shear stress and the bending stress generated in the substantially horizontal cross section with the inner wall surface 1b of the brick wall 1, and the strength of the brick wall 1 is further increased. it can. In addition, the reinforcing member 13 can be effectively arranged in a limited space without the upper insertion hole 3a and the lower insertion hole 3b interfering with each other. Furthermore, the brick wall 1 can be effectively reinforced in the state where many wall portions of the brick wall 1 are left.

また、それぞれの補強材１３同士をねじれの関係になるように配置し、内壁面１ｂと水平に交差するどの断面にも補強材１３が含まれるように配設することにより、れんが壁１をさらに効果的に補強することができる。   Further, by arranging the reinforcing members 13 so as to be in a twisted relationship and disposing the reinforcing member 13 in any cross section that intersects the inner wall surface 1b horizontally, the brick wall 1 is further increased. It can be effectively reinforced.

図５は本発明に実施例２に係る組積造構造物の補強構造を用いたれんが壁の正面図、図６は図５のＣ−Ｃ線で切断した状態の上側断面図を示す。   5 is a front view of a brick wall using the masonry structure reinforcing structure according to the second embodiment of the present invention, and FIG. 6 is an upper cross-sectional view taken along line CC in FIG.

この実施例２では、実施例１で記載した内壁面１ｂの縦方向に構成された列５ａ，５ｂを、内壁面１ｂの横方向に向けて列５ｃ，５ｄを構成したものである。この列５ｃ，５ｄは、列５ｃを上側にして、上下に間隔を置いて平行に配置されている。また、実施例１の上方向挿入孔３ａの孔方向を、挿入口４ｃから左側方向に向けることにより左方向挿入孔３ｃを形成し、実施例１の下方向挿入孔３ｂの孔方向を、挿入口４ｄから右側方向に向けることにより右方向挿入孔３ｄを形成している。   In the second embodiment, the rows 5a and 5b configured in the vertical direction of the inner wall surface 1b described in the first embodiment are arranged in the horizontal direction of the inner wall surface 1b to form the rows 5c and 5d. The rows 5c and 5d are arranged in parallel with a gap in the vertical direction with the row 5c on the upper side. Moreover, the left direction insertion hole 3c is formed by directing the hole direction of the upper direction insertion hole 3a of the first embodiment from the insertion port 4c to the left side, and the hole direction of the lower direction insertion hole 3b of the first embodiment is inserted. A right insertion hole 3d is formed by facing the right side from the opening 4d.

この構造によれば、れんが壁１を内壁面１ｂと直交する略垂直な断面で見た状態で、どの断面を取ってもその断面上に補強材１３が含まれるようにすることができる。これにより、れんが壁１の内壁面１ｂと略垂直な断面に生じるせん断応力および曲げ応力に対して、この補強材１３がせん断応力および曲げ応力に抗し、れんが壁１の強度をより高めることができる。また、挿入孔３ｃ，３ｄが互いに干渉することなく、限られたスペースの中で補強材１３を有効に配置することができる。さらに、れんが壁１の壁部を多く残した状態で、れんが壁１を効果的に補強することができる。   According to this structure, the reinforcing material 13 can be included in any cross section when the brick wall 1 is viewed in a substantially vertical cross section orthogonal to the inner wall surface 1b. As a result, the reinforcing material 13 resists the shear stress and the bending stress against the shear stress and the bending stress generated in the cross section substantially perpendicular to the inner wall surface 1b of the brick wall 1, and the strength of the brick wall 1 is further increased. it can. Further, the reinforcing material 13 can be effectively arranged in a limited space without the insertion holes 3c and 3d interfering with each other. Furthermore, the brick wall 1 can be effectively reinforced in the state where many wall portions of the brick wall 1 are left.
