Description
本発明は、耐震を目的としたレンガ構造物に使用される耐震用レンガ及びそれを用いたレンガ構造物に関する。 The present invention relates to an earthquake-resistant brick used in a brick structure intended for earthquake resistance, and a brick structure using the same.
塀などに使用される規格品レンガ２としては、一般的に国内規格レンガ（例：普通レンガ：長さ２１０ｍｍ×幅１００ｍｍ×厚さ６０ｍｍ）、オーストラリア規格レンガ、イギリス規格レンガ等が流通しており、長さ２１０～２３０ｍｍ×幅１００～１１０ｍｍ×厚さ６０～７６ｍｍで、長さ：幅：厚さの寸法比が１：約１／２：約１／３が多く、耐震目的として、規格品レンガ２に設けた３５～４０ｍｍの縦方向の貫通穴４１に直径約１０ｍｍ以上の補強鉄筋７を挿設しモルタル又はコンクリートを充填させている。また、前記国内の規格品レンガ２には、普通レンガ及び化粧レンガがある。 Standard bricks 2 used for walls etc. are generally domestic standard bricks (e.g. normal bricks: length 210mm x width 100mm x thickness 60mm), Australian standard bricks, British standard bricks, etc. , 210 to 230 mm long x 100 to 110 mm wide x 60 to 76 mm thick, with a length: width: thickness ratio of 1: about 1/2: about 1/3, and is a standard product for earthquake resistance purposes. A reinforcing reinforcing bar 7 with a diameter of about 10 mm or more is inserted into a vertical through hole 41 of 35 to 40 mm provided in the brick 2, and filled with mortar or concrete. The domestic standard bricks 2 include ordinary bricks and decorative bricks.
まず、本発明における耐震用レンガ１、規格品レンガ２の部位の名称について説明する。図１（ａ）及び図２に示すように、耐震用レンガ１、規格品レンガ２は、それぞれの面を長手１１、小口１２、胴面１３という。そして、図７（ａ）に示すように胴面１３全体の形状を全形１４、図７（ｂ）に示すように胴面の全形１４を長手の胴面１３側の辺の中央部のａ－ａ断面で切断した形状を半マス１５、図７（ｃ）に示すように胴面１３の全形１４を小口の胴面１３側の辺の中央部のｂ－ｂ断面で切断した形状をヨウカン１６、図７（ｄ）に示すように胴面１３の全形１４を長手１１の胴面１３側の辺の中央部のａ－ａ断面及び小口１２の胴面１３側の辺の中央部のｂ－ｂ断面で切断した形状を半ヨウカン１７という。 First, the names of the parts of the earthquake-resistant brick 1 and the standard brick 2 in the present invention will be explained. As shown in FIGS. 1(a) and 2, the surfaces of the earthquake-resistant brick 1 and the standard brick 2 are referred to as a long side 11, a small side 12, and a body side 13, respectively. Then, as shown in FIG. 7(a), the entire shape of the trunk surface 13 is changed to the overall shape 14, and as shown in FIG. 7(b), the entire shape 14 of the trunk surface is adjusted to The shape cut at the a-a cross section is a half square 15, and the shape cut at the bb section at the center of the side on the side of the body surface 13 of the small end is the whole shape 14 of the body surface 13, as shown in FIG. 7(c). As shown in FIG. 7(d), the entire shape 14 of the body surface 13 is the aa cross section of the center of the side on the body surface 13 side of the longitudinal length 11, and the center of the side of the edge 12 on the body surface 13 side. The shape cut along the bb section of the section is called a half-section 17.
そして、図８に示すように、耐震目的として、規格品レンガ２の胴面１３に設けた水平断面が円形状の貫通穴４１に補強鉄筋７を挿設し、前記貫通穴４１に充填材８としてモルタル又はコンクリートを充填する。そして、補強鉄筋７のモルタル又はコンクリートによる、かぶり厚さ１８は、前記貫通穴４１の周壁と補強鉄筋７の外周面との間の間隔をいい、補強鉄筋７をモルタル又はコンクリートがどれだけ取り巻いているかを意味する。耐震構造の中心は鉄筋又は鉄骨であり、鉄筋の場合は前記鉄筋をモルタル又はコンクリートで包み込むことによって錆を防ぎ強度を持続させることができる等、かぶり厚さはレンガ構造物において重要であります。 Then, as shown in FIG. 8, for the purpose of earthquake resistance, a reinforcing steel bar 7 is inserted into a through hole 41 with a circular horizontal cross section provided in the body surface 13 of the standard brick 2, and a filler material 8 is inserted into the through hole 41. Fill with mortar or concrete. The cover thickness 18 of the reinforcing reinforcing bars 7 with mortar or concrete refers to the distance between the peripheral wall of the through hole 41 and the outer peripheral surface of the reinforcing bars 7, and refers to the amount of mortar or concrete surrounding the reinforcing reinforcing bars 7. It means dolphin. The core of an earthquake-resistant structure is the reinforcing bars or steel frames, and in the case of reinforcing bars, covering the reinforcing bars with mortar or concrete prevents rust and maintains strength, and cover thickness is important in brick structures.
また、長手積みとは、図３又は図５に示すように、ジグザグに積み上げて長手１１のみを壁面にするという組積パターンであり、長手積みの場合の壁厚３０は、図３又は図４に示すように壁厚３０が規格品レンガ２の長さと略同じ約２１０～約２３０ｍｍの内のいずれかの場合の一枚積みと、図５又は図６に示すように壁厚３０が規格品レンガ２の幅である約１００～約１１０ｍｍの内のいずれかの場合の半枚積みがある。 In addition, longitudinal stacking is a masonry pattern in which the masonry is stacked in a zigzag pattern and only the long side 11 is the wall surface, as shown in FIG. 3 or 5. The wall thickness 30 in the case of longitudinal stacking is as shown in FIG. As shown in FIG. 5 or 6, the wall thickness 30 is approximately 210 to 230 mm, which is approximately the same as the length of the standard brick 2, and the wall thickness 30 is the standard brick, as shown in FIG. 5 or 6. There is a half-layered structure in which the width of the bricks 2 is about 100 to about 110 mm.
次に、背景技術である規格品レンガ２に係る問題を説明する。規格品レンガ２で塀を施工するときに、縦筋部５において、前記規格品レンガ２の直径３５～４０ｍｍの貫通穴４１に直径約１０ｍｍ以上の補強鉄筋７を１本挿設すると、補強鉄筋７の接着材８としてのモルタル又はコンクリートによるかぶり厚さ１８が１５ｍｍ以下になるので、構造計算をすることができる規定である、かぶり厚さ１８を２０ｍｍ超確保することができず、耐震構造ではないと判断されて、レンガ塀の高さを１．２ｍ以下に規制されるという問題があった。 Next, problems related to the standard brick 2, which is a background art, will be explained. When constructing a wall using standard bricks 2, if one reinforcing bar 7 with a diameter of approximately 10 mm or more is inserted into the through hole 41 with a diameter of 35 to 40 mm in the standard brick 2 in the vertical reinforcement portion 5, the reinforcing bar Since the cover thickness 18 of mortar or concrete as the adhesive 8 in 7 is less than 15 mm, it is not possible to secure the cover thickness 18 of more than 20 mm, which is the regulation that allows structural calculations, and the earthquake-resistant structure cannot be used. There was a problem in that the height of brick walls was restricted to 1.2 meters or less.
また、組積パターンを長手積みの場合の壁厚の積み方は、半枚積み又は一枚積みであるが、壁厚が狭いため、いずれであっても一般的な規格品レンガでは、かぶり厚さ２０ｍｍ超を確保できないという問題があった。 In addition, when the masonry pattern is longitudinally stacked, the wall thickness can be stacked in half-ply or single-ply, but because the wall thickness is narrow, the cover thickness is There was a problem in that it was not possible to secure a diameter of more than 20 mm.
本発明はこうした問題に鑑み創案されたもので、縦筋部の壁厚を一枚積みにでき、かぶり厚さを２０ｍｍ超確保でき、耐震構造を実現でき、塀の高さも構造計算で１．２ｍ超の高さにすることができる耐震用レンガ、及び、それを用いたレンガ構造物を提供することを課題とする。 The present invention was devised in view of these problems, and the wall thickness of the vertical reinforcement can be made into a single layer, the cover thickness can be secured to be over 20 mm, an earthquake-resistant structure can be realized, and the height of the wall can be reduced to 1. An object of the present invention is to provide an earthquake-resistant brick that can be made to a height of over 2 m, and a brick structure using the same.
本発明においてレンガ構造物とは、レンガ塀又はレンガ柱体等のレンガを積み上げて施工する構造物を意味する。また、本発明において規格品レンガとは、オーストラリア規格レンガ、イギリス規格レンガ、及び、普通レンガ又は化粧レンガのＪＩＳ規格レンガを意味する。 In the present invention, the term "brick structure" refers to a structure constructed by stacking bricks, such as a brick wall or a brick column.

The earthquake-resistant brick according to claim 1 is an earthquake-resistant brick whose long side is a decorative surface and whose maximum external dimensions are the same size as a JIS standard brick (hereinafter referred to as a standard brick) of an ordinary brick or a decorative brick. When viewed from above, one side of the body surface is half a square centering on the approximate center of the long side, and the other side of the body surface is half a square, with the long side remaining. The shape of the body surface is made into a substantially L-shape by the above-mentioned half-shaped pipe, and the inner side of two substantially perpendicular surfaces of the substantially L-shape is a mold surface.
請求項２に記載のレンガ構造物は、レンガ構造物が、縦筋部と前記縦筋部間を連結する塀とを備える長手積みのレンガ塀であって、前記縦筋部が、平面視で、壁厚を一枚積みとし、請求項１に記載の２つの耐震用レンガの半マス同士を、１辺の長さが前記規格品レンガの幅と略同じ長さの略四角形の貫通穴を略中央部に形成するように突き合わせた状態とし、前記貫通穴の周壁面を型枠面とし、前記貫通穴にモルタル又はコンクリートを充填したレンガ塀であることを特徴とする。
The brick structure according to claim 2 is a brick wall in which the brick structure is a longitudinally stacked brick wall including a vertical reinforcement portion and a wall connecting the vertical reinforcement portions, and the vertical reinforcement portion is , the wall thickness is made into a single layer, and the half-cells of the two earthquake-resistant bricks according to claim 1 are formed with substantially rectangular through holes whose length on one side is substantially the same as the width of the standard brick. The walls are characterized in that they are in a state of being butted against each other so as to be formed approximately in the center, the peripheral wall surface of the through hole is a mold surface , and the through hole is filled with mortar or concrete .
請求項３に記載のレンガ構造物は、レンガ構造物がレンガ柱体であって、平面視で、壁厚を一枚積みとし、請求項１に記載の２つの耐震用レンガの半マス同士を、１辺の長さが前記規格品レンガの幅と略同じ長さの略四角形の貫通穴を略中央部に形成するように突き合わせた状態とし、前記貫通穴の周壁面を型枠面とし、前記貫通穴にモルタル又はコンクリートを充填したレンガ柱体であることを特徴とする。
In the brick structure according to claim 3, the brick structure is a brick column body, and the wall thickness is a single layer in plan view, and the two earthquake-resistant bricks according to claim 1 are stacked half squares apart. , the length of one side is approximately the same as the width of the standard brick, and the bricks are butted together to form a substantially square through hole approximately in the center, and the peripheral wall surface of the through hole is the formwork surface. , characterized in that it is a brick column whose through hole is filled with mortar or concrete .
請求項１に記載の耐震用レンガは、規格品レンガと最大長さ・最大幅・厚さは同じでありながら、Ｌ字形の２つを組み合わせることにより、壁厚が規格品レンガの長さとほぼ同じ寸法の幅の一枚積みでありながら、一辺が規格品レンガの幅とほぼ同じ約１００ｍｍ強の四角形の貫通穴を形成させることができ、前記貫通穴の内壁面を型枠面として鉄筋コンクリート造又は鉄骨造を施工させることができる。 The earthquake-resistant brick according to claim 1 has the same maximum length, maximum width, and thickness as the standard brick, but by combining two L-shaped pieces, the wall thickness is almost the same as the length of the standard brick. Although it is a single layer of bricks with the same dimensions and width, it is possible to form a rectangular through hole with one side approximately 100 mm or more, which is approximately the same width as the standard product brick, and use the inner wall surface of the through hole as the formwork surface to form a reinforced concrete structure. Alternatively, a steel frame structure can be constructed.
前記耐震用レンガと規格品レンガとは、最大長さ・最大幅・厚さが同じであるので、本発明の耐震用レンガを用いて施工するときに、規格品レンガは一般的に流通しているので調達コストを抑制でき利便性がよいという効果を奏する。 The earthquake-resistant bricks and the standard bricks have the same maximum length, maximum width, and thickness, so when constructing using the earthquake-resistant bricks of the present invention, the standard bricks are generally distributed. This has the effect of reducing procurement costs and providing convenience.
請求項２に記載のレンガ構造物のレンガ塀は、壁厚が一枚積みで規格品レンガの長さと略同じ寸法の厚さ（普通レンガで約２１０ｍｍ）でありながら、規格品レンガの幅（普通レンガで約１００ｍｍ）の寸法と目地約１０ｍｍを加算した約１００ｍｍ以上を１辺の長さとする四角形の貫通穴の周壁面を型枠面としてモルタル又はコンクリートを充填した、補強鉄筋のモルタル又はコンクリートによるかぶり厚さを２０ｍｍ超にすることができるので、鉄筋コンクリート造又は鉄骨造を施工するときと同じ構造計算が可能であるので、これにより積み上げ高さを１．２ｍ超にすることができ、フェンスを立設させることができる。 The brick wall of the brick structure according to claim 2 has a wall thickness that is approximately the same as the length of the standard brick (approximately 210 mm for a regular brick), but the width of the standard brick (approximately 210 mm). Mortar or concrete for reinforcing reinforcing bars, filled with mortar or concrete using the peripheral wall surface of a rectangular through hole whose side length is approximately 100 mm or more, which is the sum of the dimensions of a regular brick (approximately 100 mm) and the joint approximately 10 mm. Since the cover thickness can be made over 20 mm, the same structural calculation as when constructing a reinforced concrete or steel structure is possible, so the stacking height can be increased to over 1.2 m, and the fence can be erected.
規格品レンガの幅（普通レンガで約１００ｍｍ）と略同じ寸法の四角形の型枠から造られる鉄筋コンクリート造又は鉄骨造を施工でき、鉄筋又は鉄骨のモルタル又はコンクリートによる、かぶり厚さを２０ｍｍ超確保できながら、壁面全体を化粧面である長手のみにする長手積みができ、壁厚を規格品レンガの長さ（普通レンガで約２１０ｍｍ）にできる。 Reinforced concrete or steel structures can be constructed from rectangular formwork with dimensions approximately the same as the width of standard bricks (approximately 100 mm for regular bricks), and a cover thickness of more than 20 mm can be secured with mortar or concrete for the reinforcing bars or steel frames. However, it is possible to stack the entire wall surface only in the longitudinal direction, which is a decorative surface, and the wall thickness can be made to the length of standard bricks (about 210 mm for regular bricks).
壁厚が一枚積みで、組積パターンが長手積みにおいて、規格品レンガ又は耐震用レンガをジグザグに積み上げるが、長手の長辺の略中央部で半マスと半ヨウカンとを分けたことによって、平面視で各段の貫通穴の位置は略同位置とすることができ、貫通穴が狭まれることがない。これにより、鉄筋又は鉄骨のモルタル又はコンクリートによる、かぶり厚さが不足することはない。 When the wall thickness is one layer and the masonry pattern is longitudinal, standard bricks or earthquake-resistant bricks are piled up in a zigzag pattern, but by dividing the half square and half square blocks approximately at the center of the long side, The positions of the through holes in each stage can be made to be approximately the same in plan view, and the through holes are not narrowed. As a result, the covering thickness of the reinforcing bars or steel frames with mortar or concrete will not be insufficient.
請求項３に記載のレンガ構造物のレンガ柱体は、壁厚が一枚積みで規格品レンガの長さと略同じ寸法の厚さ（普通レンガで約２１０ｍｍ）でありながら、規格品レンガの幅（普通レンガで約１００ｍｍ）の寸法と目地約１０ｍｍを加算した約１００ｍｍ以上を１辺の長さとする四角形の貫通穴の周壁面を型枠面として接着材であるモルタル又はコンクリートを充填した、補強鉄筋のモルタル又はコンクリートによるかぶり厚さを２０ｍｍ超にすることができるので、鉄筋コンクリート造又は鉄骨造を施工するときと同じ構造計算が可能であるので、これにより積み上げ高さを１．２ｍ超にすることができる。 The brick column body of the brick structure according to claim 3 has a wall thickness of a single layer and a thickness that is approximately the same as the length of the standard brick (about 210 mm for a regular brick), but a width of the standard brick. (approximately 100 mm for ordinary bricks) and the joint length of approximately 10 mm, which is approximately 100 mm or more on one side.The peripheral wall surface of a rectangular through hole is used as the formwork surface and is filled with mortar or concrete as an adhesive material. Since the covering thickness of the reinforcing bars with mortar or concrete can exceed 20 mm, the same structural calculations as when constructing reinforced concrete or steel structures are possible, so the stacking height can be increased to over 1.2 m. be able to.
塀は面外の転倒に対する抵抗要素として控壁・控柱を必要とすると定めてあるが、都市部では一般に敷地が狭小なため、建物と隣地境界との間は狭く、控壁が造りにくい場合が多いため、重要な構造要素が欠落していて、地震に対して不利な実情がある。これに対して、本発明のレンガ柱体を設置すれば、鉄筋又は鉄骨のモルタル又はコンクリートによる、かぶり厚さが２０ｍｍ超であるので、鉄筋コンクリート造又は鉄骨造を施工できるので、都市部の敷地が狭小な場所においても塀の転倒防止を図ることができるという効果を奏する。 It is stipulated that walls and buttresses are required for walls to resist overturning, but in urban areas, sites are generally small, and the distance between the building and the border of the neighboring property is narrow, making it difficult to construct a retaining wall. Because of this, many buildings lack important structural elements, making them disadvantageous against earthquakes. On the other hand, if the brick pillar body of the present invention is installed, the cover thickness of the mortar or concrete of the reinforcing bars or steel frame is more than 20 mm, so reinforced concrete construction or steel frame construction can be constructed, so that urban sites can be used. This has the effect of preventing the fence from falling even in a narrow space.
本発明の耐震用レンガ１は、図１（ａ）に示すように、長手１１を化粧面とする、最大外形寸法（長さＡ×幅Ｂ×厚さＣ）が、図２に示す規格品レンガ２（長さＡ×幅Ｂ×厚さＣ）と同じ大きさの耐震用レンガ１であって、平面視で、長手１１の長辺の略中央部を中心として片側の胴面１３は半マス１５で、他の片側の胴面１３は長手１１側を残した半ヨウカン１７で、平面視で前記半マス１５と前記半ヨウカン１７とにより前記胴面１３の形状を略Ｌ字形とし、前記略Ｌ字形の略直交する２面の内側が、鉄筋コンクリート造又は鉄骨造を可能とする型枠面４となる耐震用レンガ１である。 As shown in FIG. 1(a), the earthquake-resistant brick 1 of the present invention is a standard product with maximum external dimensions (length A x width B x thickness C) shown in FIG. It is an earthquake-resistant brick 1 having the same size as the brick 2 (length A x width B x thickness C), and when viewed from above, the body surface 13 on one side is half-shaped around the center of the long side 11. In the square 15, the body surface 13 on the other side is a half-length span 17 with the longitudinal side 11 left intact, and the shape of the body face 13 is approximately L-shaped by the half-mass 15 and the half-stroke span 17 in plan view. The inner sides of two substantially L-shaped substantially perpendicular surfaces are the earthquake-resistant bricks 1 that serve as formwork surfaces 4 that enable reinforced concrete construction or steel frame construction.
前記耐震用レンガ１は、図１又は図２に示すように、最大長さＡ・最大幅Ｂ・厚さＣを、オーストラリアレンガ、イギリスレンガ、及び、普通レンガ又は化粧レンガの大きさを規定したＪＩＳ規格のレンガ等の規格品レンガ２と同じにしている。このため、調達しやすい規格品レンガ２と組み合わせてレンガ塀なるレンガ構造物を施工することができる。 As shown in FIG. 1 or 2, the earthquake-resistant brick 1 has a maximum length A, a maximum width B, and a thickness C that are the same as those of Australian bricks, British bricks, and ordinary bricks or decorative bricks. It is the same as standard product brick 2 such as JIS standard brick. Therefore, a brick structure called a brick wall can be constructed in combination with standard bricks 2 that are easy to procure.
また、図１（ａ）に示すように、平面視で胴面１３の形状が、長手１１の長辺の略中央部を中心として片側は半マス１５で他の片側は半ヨウカン１７からなる略Ｌ字形であり、図１（ｂ）に示すように、２つのＬ字形の耐震用レンガ１の半マス１５を突き合わせて、壁厚３０が規格品レンガ２の長さＡ（普通レンガで約２１０ｍｍ）でありながら、規格品レンガ２の幅Ｂ（普通レンガの場合約１００ｍｍ）の長さと目地幅約１０ｍｍを加算した長さＢ１を一辺とする略四角形の貫通穴４０を、中央部に形成させることができ、鉄筋又は鉄骨のモルタル又はコンクリートによる、かぶり厚さ１８を２０ｍｍ超確保でき、該貫通穴４０の側面を、鉄筋コンクリート造又は鉄骨造が施工可能な型枠面４とすることができる。 In addition, as shown in FIG. 1(a), the shape of the trunk surface 13 in plan view is approximately composed of a half square 15 on one side and a half square 17 on the other side with the center of the long side 11 as the center. As shown in Figure 1(b), the wall thickness 30 is the length A of the standard brick 2 (approximately 210 mm for regular bricks). ), a substantially rectangular through hole 40 is formed in the center, with one side being the length B1, which is the sum of the width B of the standard brick 2 (approximately 100 mm in the case of ordinary bricks) and the joint width of approximately 10 mm. It is possible to secure a cover thickness 18 of more than 20 mm with mortar or concrete of the reinforcing bars or steel frame, and the side surface of the through hole 40 can be used as the formwork surface 4 on which reinforced concrete construction or steel construction can be constructed.
また、前記半マス１５と前記半ヨウカン１７からなる長手１１を残してあるので、化粧面である長手１１をレンガ塀やレンガ門柱の壁面にすることができる。 Further, since the long side 11 consisting of the half square 15 and the half wall 17 is left, the long side 11, which is a decorative surface, can be used as a wall surface of a brick wall or a brick gatepost.
したがって、前記耐震用レンガ１を使用することによって、壁厚３０が規格品レンガ２の長さＡの一枚積みでありながら、一辺が規格品レンガ２の幅Ｂ（規格品レンガ２の長さＡの略半分の長さである。）とほぼ同じ１００ｍｍ強の四角形の貫通穴４０を形成させることができ、鉄筋又は鉄骨のモルタル又はコンクリートによる、かぶり厚さ１８を２０ｍｍ超にすることができ、前記貫通穴４０の内壁面を型枠面４として鉄筋コンクリート造又は鉄骨造を施工させることができ、さらにレンガ塀の壁面を化粧面である長手１１のみにすることができる。 Therefore, by using the earthquake-resistant bricks 1, although the wall thickness 30 is a single layer with the length A of the standard bricks 2, one side is the width B of the standard bricks 2 (the length of the standard bricks 2). It is possible to form a rectangular through hole 40 of just over 100 mm, which is approximately half the length of A), and it is possible to make the covering thickness 18 of the reinforcing bars or steel frame with mortar or concrete over 20 mm. A reinforced concrete structure or a steel frame structure can be constructed using the inner wall surface of the through hole 40 as the formwork surface 4, and furthermore, the wall surface of the brick wall can be made only of the longitudinal side 11 which is a decorative surface.
次に、本発明のレンガ構造物のレンガ塀２０について説明する。図２、図３、図４に示すように、レンガ構造物が、縦筋部５と前記縦筋部５間を連結する塀３５とを備える長手積みのレンガ塀２０であって、前記縦筋部５が、平面視で、壁厚３０を一枚積みとし、前記２つの耐震用レンガ１の半マス１５同士を、１辺の長さが前記規格品レンガ２の幅Ｂと略同じ長さの略四角形の貫通穴４０を略中央部に形成するように突き合わせた状態とし、前記貫通穴４０の周壁面を型枠面４とした、鉄筋コンクリート造又は鉄骨造の形態となるレンガ塀２０である。 Next, the brick wall 20 of the brick structure of the present invention will be explained. As shown in FIGS. 2, 3, and 4, the brick structure is a longitudinally stacked brick wall 20 comprising vertical reinforcement portions 5 and a wall 35 connecting the vertical reinforcement portions 5. The section 5 has a wall thickness of 30 when viewed from above, and the half squares 15 of the two earthquake-resistant bricks 1 are arranged so that the length of one side is approximately the same as the width B of the standard brick 2. This brick wall 20 is made of reinforced concrete or steel frame, with a substantially square through hole 40 formed in a substantially central portion of the walls facing each other, and a peripheral wall surface of the through hole 40 serving as a formwork surface 4. .

First, although not shown, reinforcing bars or steel frames are fixed to the foundation and erected. Then, while filling the joints 9 with mortar as the adhesive 8, and filling the through holes 40 into which the reinforcing reinforcing bars 7 (not shown) have been inserted with mortar or concrete, one stage is created so that the arrangement shown in FIG. Build eyes. Note that reinforcing bars or steel frames, as well as mortar or concrete are not shown in FIGS. 9 to 11.
このときに、平面視で、壁厚３０を一枚積みとし、２つの耐震用レンガ１の半マス１５同士を、１辺の長さが前記規格品レンガ２の幅Ｂと略同じ長さの略四角形の貫通穴４０を略中央部に形成するように突き合わせた状態とし、前記貫通穴４０の周壁面を型枠面４として鉄筋コンクリート造又は鉄骨造を造る。 At this time, when viewed from above, the wall thickness 30 is assumed to be one layer, and the half squares 15 of the two earthquake-resistant bricks 1 are arranged so that the length of one side is approximately the same as the width B of the standard brick 2. A substantially rectangular through hole 40 is abutted to each other so as to be formed approximately in the center, and a reinforced concrete structure or a steel frame structure is constructed by using the peripheral wall surface of the through hole 40 as a formwork surface 4.
次に、２段目は、図１０に示すように、１段目とは耐震用レンガ１と規格品レンガ２とがジグザグになるように、目地にモルタルを充填し、補強鉄筋７（図示なし）を挿設した貫通穴４０にはモルタル又はコンクリートを充填しながら積み上げる。次に、３段目は図１１に示すように、図９に示す１段目と略同じ配置で耐震用レンガ１と規格品レンガ２とを配置し、目地にモルタルを充填し、補強鉄筋７（図示なし）を挿設した貫通穴４０にはモルタル又はコンクリートを充填しながら積み上げる。予め設定した積み上げ数まで繰り返してレンガ柱体３を造る。 Next, as shown in FIG. 10, in the second stage, the joints are filled with mortar so that the seismic bricks 1 and the standard bricks 2 are arranged in a zigzag pattern, and reinforcing reinforcing bars 7 (not shown) are formed. ) are stacked while filling the through holes 40 with mortar or concrete. Next, in the third stage, as shown in FIG. 11, earthquake-resistant bricks 1 and standard bricks 2 are placed in approximately the same arrangement as the first stage shown in FIG. The through holes 40 (not shown) are filled with mortar or concrete and piled up. Brick columns 3 are built by repeating the process until a preset number of stacks are stacked.
前記レンガ柱体３の活用例として、図５や図６に示すようなレンガ塀２３や、図１２に示すようなレンガ門柱３８がある。 Examples of the use of the brick pillar body 3 include a brick wall 23 as shown in FIGS. 5 and 6, and a brick gatepost 38 as shown in FIG. 12.
次に、前記レンガ塀２３について説明する、前記レンガ塀２３は、図５又は図６に示すように、縦筋部５と前記縦筋部５間を連結する塀３５とを備えるレンガ塀２３であって、組積パターンが長手積みで、塀３５の壁厚３１が半枚積みで、縦筋部５のレンガ柱体３の壁厚３０が一枚積みである。 Next, the brick wall 23 will be explained. As shown in FIG. 5 or 6, the brick wall 23 is a brick wall 23 that includes vertical reinforcement portions 5 and a wall 35 that connects the vertical reinforcement portions 5. The masonry pattern is longitudinal, the wall thickness 31 of the fence 35 is half-walled, and the wall thickness 30 of the brick columns 3 of the vertical reinforcement portion 5 is single-walled.
また、図５のｃ列２４を図６（ａ）に示し、前記ｃ列２４の１段下の図５のｄ列２５を図６（ｂ）に示すように、前記半マス１５と前記半ヨウカン１７との境界を長手１１の長辺の略中央部としたことにより、前記貫通穴４０の周壁面である型枠面４の位置は、平面視で略同じ位置にすることができるので、鉄筋又は鉄骨のモルタル又はコンクリートによる、かぶり厚さ１８が２０ｍｍ以下になることはない。 Further, as shown in FIG. 6(a) is the c column 24 in FIG. 5, and as shown in FIG. 6(b) is the d column 25 in FIG. By setting the boundary with the holder 17 at approximately the center of the long side of the longitudinal side 11, the position of the formwork surface 4, which is the peripheral wall surface of the through hole 40, can be at approximately the same position in plan view. The cover thickness 18 of reinforcing bars or steel frames with mortar or concrete cannot be less than 20 mm.
前記縦筋部５のレンガ柱体３が鉄筋コンクリート造又は鉄骨造であるので耐震力があり、かつ壁厚３０が規格品レンガ２の長さＡの寸法しかないので、都市部の敷地が狭小な場所においても塀の転倒防止を図ることができる。 Since the brick column body 3 of the vertical reinforcement section 5 is made of reinforced concrete or steel frame construction, it has earthquake resistance, and the wall thickness 30 is only the length A of the standard brick 2, so it is suitable for narrow sites in urban areas. It is also possible to prevent the fence from falling over at any location.
次に、前記レンガ門柱３８について説明する。前記レンガ門柱３８は、図１２に示すように、前記レンガ柱体３とほぼ同じ構成である。壁厚３０が規格品レンガ２の長さＡの寸法しかないので、都市部の敷地が狭小な場所においても高い耐震性を有するレンガ門柱３８を造ることができる。 Next, the brick gatepost 38 will be explained. The brick gatepost 38 has almost the same configuration as the brick column body 3, as shown in FIG. Since the wall thickness 30 is only the length A of the standard brick 2, the brick gate post 38 can be built with high earthquake resistance even in a narrow urban site.
