Description

この発明は、鉄筋コンクリート造又は鉄骨鉄筋コンクリート造の既存建物の耐震補強方法の技術分野に属し、更に云うと、建物を支持する杭等の地下躯体や柱、梁の上部躯体の補強が殆ど不要で、耐震効果と制震効果とを発揮させることができる耐震補強方法と耐震壁に関する。 This invention belongs to the technical field of the seismic reinforcement method for existing buildings of reinforced concrete or steel reinforced concrete, and more specifically, there is almost no need to reinforce underground structures such as piles and pillars that support buildings, and upper structures of beams, The present invention relates to a seismic reinforcement method and a seismic wall that can exhibit seismic and seismic control effects.

従来の既存建物の耐震補強方法は、既存建物の柱と梁(又はスラブ)とで形成される架構面内に、補強部材として耐震壁を設置するのが一般的である。例えば、(i)特許文献1の耐震補強方法は、架構面内に人力で運搬可能な大きさにブロック化された鋼製ブロック部材(溝形鋼)を組み込んで耐震壁を設置し、既存建物を補強している。   In a conventional seismic reinforcement method for an existing building, a seismic wall is generally installed as a reinforcing member in a frame surface formed by columns and beams (or slabs) of the existing building. For example, (i) the seismic reinforcement method of Patent Document 1 is to install a seismic wall by incorporating a steel block member (grooved steel) that is blocked to a size that can be transported by manpower in the frame, Is reinforced.

(ii)特許文献2の耐震補強方法は、架構面内に極低降伏点鋼壁パネルと高張力鋼壁パネルとを交互に組み込んで耐震壁を設置し、既存建物を補強している。 (Ii) The seismic reinforcement method of Patent Document 2 reinforces an existing building by alternately installing ultra-low yield point steel wall panels and high-strength steel wall panels in the frame and installing seismic walls.

(iii)特許文献3の耐震補強方法は、コンクリート壁にスリットを形成した後に、同コンクリート壁を予めスリットを形成した鋼板で挟み込み耐震壁とし、既存建物を補強している。 (Iii) In the seismic reinforcement method of Patent Document 3, after a slit is formed in a concrete wall, the concrete wall is sandwiched with steel plates in which slits are formed in advance to form a seismic wall, thereby reinforcing an existing building.

(iv)なお、特許文献4には、建物の架構面内に波形鋼板を遮災壁として設置する技術が開示されている。 (Iv) It should be noted that Patent Document 4 discloses a technique for installing a corrugated steel plate as a disaster-shielding wall in the frame of a building.

上記特許文献1〜3の耐震補強方法は、十分な耐震性能を発揮させるために、耐震壁を剛強な溝形鋼や鋼板で構成している。そのため、耐震壁が重量物と成り、建物を支持する杭等の地下躯体や柱、梁の上部躯体の補強が必要である。つまり、補強作業が大掛かりで、工期が長期化するだけでなく、コストが嵩む問題点を有する。   In the seismic strengthening methods of Patent Documents 1 to 3, the seismic wall is made of a rigid channel steel or steel plate in order to exhibit sufficient seismic performance. For this reason, the seismic walls are heavy, and it is necessary to reinforce underground structures such as piles and pillars that support the building, and upper structures of beams. That is, there is a problem that the reinforcement work is large and not only the construction period is lengthened but also the cost is increased.

また、溝形鋼や鋼板は軸力に対して大きな剛性、耐力を発揮するので、架構の柱が建物の長期荷重によって、又は鉄筋コンクリート造又は鉄骨鉄筋コンクリート造であるが故のコンクリートのクリープ、乾燥収縮に起源する軸力が地下躯体や上部躯体に伝達される。そのため、やはり地下躯体や上部躯体の補強が必要となり、補強作業が大掛かりで、工期が長期化するだけでなく、コストが嵩む問題点を有する。   In addition, since channel steel and steel plate exhibit great rigidity and proof strength against axial force, concrete creep and drying shrinkage due to the long-term load of the building, reinforced concrete structure or steel reinforced concrete structure. Axial force originating from is transmitted to the underground and upper frame. For this reason, it is necessary to reinforce the underground and upper frames, which requires a large amount of reinforcement work and not only lengthens the construction period but also increases costs.

ところで、波形鋼板の力学的特性について着目すると、次の特徴が認められる。なお、波形鋼板とは、単に折り板とか波板とも称されるもので、断面形状としては、図21(A)〜(D)に例示した台形波形状(A)、矩形波形状(B)、三角波形状(C)、円弧波形状(D)などがある。   By the way, paying attention to the mechanical characteristics of the corrugated steel sheet, the following features are recognized. The corrugated steel sheet is also simply referred to as a folded plate or a corrugated sheet, and the cross-sectional shapes include a trapezoidal wave shape (A) and a rectangular wave shape (B) illustrated in FIGS. 21 (A) to (D). , Triangular wave shape (C), circular wave shape (D), and the like.

(せん断力に対して) (For shear force)

図17に例示したように、波形鋼板は、折り板になっている一枚一枚がせん断力に対して抵抗し、その集合としての全体がせん断力に抵抗する。そして、せん断座屈長さが短く、そのせん断強度を平板と比較した場合、せん断耐力ははるかに大きい。 As illustrated in FIG. 17, in the corrugated steel sheet, each one of the folded plates resists the shearing force, and the whole as a set resists the shearing force. And when shear buckling length is short and the shear strength is compared with a flat plate, shear strength is much larger.

一方、図18に例示するように、波形鋼板の筋と直角なせん断力に対してはアコーディオンの如く自由に伸びて抵抗しない。   On the other hand, as illustrated in FIG. 18, the shearing force perpendicular to the corrugated steel bar does not resist the shear force extending freely like an accordion.

(軸力及び曲げに対して)   (For axial force and bending)

波形鋼板の筋に直角な軸力に対しては、図19に例示したようにアコーディオンの如く自由に伸び縮みして、平板に比較すると剛性、耐力ははるかに小さい。また、面内の曲げに対しても、図20に例示したようにアコーディオンの如く自由に伸び縮みして、平板に比較すると剛性、耐力ははるかに小さい。 As shown in FIG. 19, the axial force perpendicular to the corrugated steel strip expands and contracts freely like an accordion, and its rigidity and proof stress are much smaller than those of a flat plate. Also, with respect to in-plane bending, as shown in FIG. 20, it expands and contracts freely like an accordion, and its rigidity and proof stress are much smaller than that of a flat plate.

しかし、特許文献4の波形鋼板は遮災壁として採用されているので、同波形鋼板を降伏させて地震エネルギーを吸収させる技術的思想はなく、制震効果は期待できない。   However, since the corrugated steel sheet of Patent Document 4 is adopted as a disaster-shielding wall, there is no technical idea for yielding the corrugated steel sheet to absorb seismic energy, and a seismic control effect cannot be expected.

そこで本発明の目的は、上記した力学的特性を有する波形鋼板を、既存建物の柱・梁架構又は柱・スラブ架構の面内に、補強部材として前記波形鋼板の筋を水平方向に向けて嵌め込むことで、既存建物を軽量に、しかも地下躯体や上部躯体に軸力を伝達しない構成で耐震補強することができ、それ故に前記地下躯体や上部躯体の補強を殆ど不要として、施工を容易にし、工期の短縮とコストの削減に寄与できる既存建物の耐震補強方法と耐震壁を提供することである。 Accordingly, an object of the present invention is to fit a corrugated steel sheet having the above-mentioned mechanical characteristics into a plane of a column / beam frame or a column / slab frame of an existing building with the reinforcing bars of the corrugated steel sheet facing the horizontal direction. Therefore, the existing building can be seismically reinforced with a structure that is lightweight and does not transmit axial force to the underground or upper frame, and therefore the reinforcement of the underground or upper frame is almost unnecessary, facilitating construction. To provide a seismic reinforcement method and seismic walls for existing buildings that can contribute to shortening the construction period and reducing costs.

本発明の次の目的は、波形鋼板を降伏させて制震効果を発揮させることができる、既存建物の耐震補強方法と耐震壁を提供することである。 The next object of the present invention is to provide a seismic reinforcement method and a seismic wall for an existing building that can yield a seismic control effect by yielding a corrugated steel sheet.

本発明に係る既存建物の耐震補強方法において、架構面内に補強部材として嵌め入れた波形鋼板は、折り板になっている一枚一枚がせん断力に抵抗し、その集合としての全体がせん断力に抵抗する性状なので、架構の剛性が高まり、地震による水平力に対して波形鋼板が抵抗し十分な耐震効果を発揮する。   In the seismic reinforcement method for an existing building according to the present invention, each corrugated steel sheet fitted as a reinforcing member in the frame surface resists shearing force one by one, and the whole as a set shears. Because it is resistant to force, the rigidity of the frame is increased, and the corrugated steel plate resists the horizontal force caused by the earthquake and exhibits a sufficient seismic effect.

つまり、波形鋼板は平板に比べて軽量でありながら、十分な耐震性能を発揮するので、既存建物を軽量な構成で耐震補強することができ、杭等の地下躯体や柱、梁の上部躯体への影響が少なく、殆ど補強する必要がない。そのため、耐震補強の施工が容易で、工期の短縮とコストの削減に寄与できる。   In other words, corrugated steel sheets are lighter than flat plates but exhibit sufficient seismic performance, so existing buildings can be seismically reinforced with a lightweight construction, and can be used for underground structures such as piles, columns, and upper structures of beams. There is little need to reinforce. Therefore, it is easy to install seismic reinforcement, which can contribute to shortening the construction period and reducing costs.

また、波形鋼板は軸力に対して、アコーディオンの如く自由に伸び縮みして抵抗しないので、鉄筋コンクリート造又は鉄骨鉄筋コンクリート造であるが故のコンクリートのクリープ、乾燥収縮に起源する軸力を地下躯体や上部躯体に伝達しない。そのため、やはり地下躯体や上部躯体を殆ど補強する必要がなく、耐震補強の施工が容易で、工期の短縮とコストの削減に寄与できる。   In addition, corrugated steel sheet does not resist and resists axial force like an accordion. Do not transmit to the upper housing. For this reason, it is not necessary to reinforce the underground frame or the upper frame, and it is easy to perform seismic reinforcement, contributing to shortening the construction period and reducing costs.

しかも、波形鋼板を降伏させて、地震エネルギーを吸収させることができるので、高い制震効果を発揮させることができる。   Moreover, since the corrugated steel sheet can be yielded and the seismic energy can be absorbed, a high seismic control effect can be exhibited.

既存建物の柱・梁架構又は柱・スラブ架構の面内に補強部材として波形鋼板を、その筋を水平方向に向けて架構との間で水平力の伝達が可能に嵌め入れる。   A corrugated steel plate is fitted as a reinforcing member in the plane of a column / beam frame or a column / slab frame of an existing building, and the reinforcement is fitted in the horizontal direction so that horizontal force can be transmitted between the frame and the frame.

請求項1、2、3及び請求項10並びに請求項13に記載した発明に係る既存建物の耐震補強方法の実施例を、図1及び図2に基づいて説明する。 Embodiments of the seismic reinforcement method for an existing building according to the inventions described in claims 1 , 2 , 3, 10 , and 13 will be described with reference to FIGS. 1 and 2.

図1及び図2に示す実施例は、鉄筋コンクリート造又は鉄骨鉄筋コンクリート造の既存建物の柱1と梁2とで形成される架構3の面内に補強部材としてフレーム付き波形鋼板4を嵌め入れて補強している。   The embodiment shown in FIGS. 1 and 2 is reinforced by fitting a corrugated steel plate 4 with a frame as a reinforcing member in a plane of a frame 3 formed by columns 1 and beams 2 of an existing building of reinforced concrete structure or steel reinforced concrete structure. is doing.

具体的には、先ず架構3の内周全面にスタッド5を取り付ける。   Specifically, the stud 5 is first attached to the entire inner peripheral surface of the frame 3.

前記架構3の面内に嵌め入れるフレーム付き波形鋼板4は、低降伏点鋼から成る単位波形鋼板6を一枚の大版とし、その単位波形鋼板6の外周各辺に、スタッド7を取り付けたプレート8を接合してフレーム9を形成した構成としており、工場などで予め組み上げて現場サイトに搬入する(請求項10及び請求項13記載の発明)。ちなみに、単位波形鋼板6の板厚の大きさ(通例9mm〜22mm程度)、波形のピッチ(通例500mm〜700mm程度)及び波高の大きさ(通例80mm〜150mm程度)は、所定のせん断耐力及び剛性を発現するように設計する。 The corrugated steel sheet 4 with a frame to be fitted in the surface of the frame 3 is a single corrugated steel sheet 6 made of low yield point steel, and a stud 7 is attached to each outer peripheral side of the corrugated steel sheet 6. The frame 9 is formed by joining the plates 8 and is assembled in advance at a factory or the like and carried into a site (claims 10 and 13 ). Incidentally, the thickness of the corrugated steel sheet 6 (typically about 9 mm to 22 mm), the pitch of the corrugation (typically about 500 mm to 700 mm), and the magnitude of the wave height (typically about 80 mm to 150 mm) are set to a predetermined shear strength and rigidity. Is designed to express.

架構3の面内に、上記構成のフレーム付き波形鋼板4を、その単位波形鋼板6の筋を水平方向に向けて嵌め入れ、架構3の内周面とフレーム付き波形鋼板4のフレーム外周面との間に無収縮モルタル10を充填する。その結果、フレーム付き波形鋼板4の単位波形鋼板6と架構3との間で水平力の伝達が可能な構成となり、上述したように、単位波形鋼板6は折り板になっている一枚一枚がせん断力に抵抗し、その集合としての全体がせん断力に抵抗する性状なので(図17を参照)、架構3の剛性が高まり、地震による水平力に対して単位波形鋼板6が抵抗し十分な耐震効果を発揮する。   In the surface of the frame 3, the corrugated steel plate 4 with the above-mentioned structure is fitted with the stripes of the unit corrugated steel plate 6 facing the horizontal direction, and the inner peripheral surface of the frame 3 and the outer peripheral surface of the frame of the corrugated steel plate 4 with the frame In between, the non-shrink mortar 10 is filled. As a result, it becomes the structure which can transmit a horizontal force between the unit corrugated steel plate 6 and the frame 3 of the corrugated steel plate 4 with the frame, and as described above, the unit corrugated steel plate 6 is a folded plate one by one. Is resistant to shearing force and the aggregate as a whole is resistant to shearing force (see FIG. 17), so that the rigidity of the frame 3 is increased, and the unit corrugated steel plate 6 resists the horizontal force due to the earthquake and is sufficient. Demonstrate earthquake resistance.

つまり、フレーム付き波形鋼板4の単位波形鋼板6は平板に比べて軽量でありながら、十分な耐震性能を発揮するので、既存建物を軽量な構成で耐震補強することができ、杭等の地下躯体や柱1、梁2の上部躯体への影響が少なく、殆ど補強する必要がない。そのため、耐震補強の施工が容易で、工期の短縮とコストの削減に寄与できる。   In other words, the unit corrugated steel sheet 6 of the corrugated steel sheet 4 with a frame is lighter than a flat plate and exhibits sufficient seismic performance. Therefore, the existing building can be seismically reinforced with a light construction, and underground structures such as piles. There is little influence on the upper frame of the column 1 and the beam 2 and there is almost no need to reinforce. Therefore, it is easy to install seismic reinforcement, which can contribute to shortening the construction period and reducing costs.

また、フレーム付き波形鋼板4の単位波形鋼板6は軸力に対して、上述したようにアコーディオンの如く自由に伸び縮みして抵抗しないので、鉄筋コンクリート造又は鉄骨鉄筋コンクリート造であるが故のコンクリートのクリープ、乾燥収縮に起源する軸力を地下躯体や上部躯体に伝達しない(図19を参照)。そのため、やはり地下躯体や上部躯体を殆ど補強する必要がなく、耐震補強の施工が容易で、工期の短縮とコストの削減に寄与できる。   In addition, the unit corrugated steel plate 6 of the corrugated steel plate 4 with the frame is free from expansion and contraction with respect to the axial force, as described above, so that it does not resist. Therefore, the creep of the concrete because it is reinforced concrete or steel reinforced concrete. The axial force originating from the drying shrinkage is not transmitted to the underground frame or the upper frame (see FIG. 19). For this reason, it is not necessary to reinforce the underground frame or the upper frame, and it is easy to perform seismic reinforcement, contributing to shortening the construction period and reducing costs.

しかも、フレーム付き波形鋼板4の単位波形鋼板6を降伏させて、地震エネルギーを吸収させることができるので、高い制震効果を発揮させることができる。   In addition, since the unit corrugated steel sheet 6 of the corrugated steel sheet 4 with a frame can be yielded and seismic energy can be absorbed, a high seismic control effect can be exhibited.

That is, as illustrated in FIG. 8, a plurality of (three in FIG. 8) unit corrugated steel plates 6 may be overlapped to form a frame 9 on the outer periphery thereof (the invention according to claim 10 ).

図9及び図10に示す実施例は、スタッド7を外周縁部に取り付けた波形鋼板16を架構3の面内に嵌め入れて補強しており、前記スタッド7を外周縁部に取り付けた波形鋼板16は低降伏点鋼から成る一枚の単位波形鋼板6を大版とし、その外周四辺の縁部にスタッド7を取り付けた構成としている(請求項及び請求項12記載の発明)。 In the embodiment shown in FIGS. 9 and 10, the corrugated steel plate 16 with the stud 7 attached to the outer peripheral edge portion is reinforced by fitting it in the plane of the frame 3, and the stud 7 is attached to the outer peripheral edge portion. Reference numeral 16 denotes a unit corrugated steel plate 6 made of a low yield point steel having a large plate, and studs 7 are attached to the edges of the outer periphery of the steel plate (inventions according to claims 8 and 12 ).

A non-shrinkable mortar 10 is filled between the frame and the inner peripheral surface of the frame 3 so that a horizontal force can be transmitted between the frame 3 and the frame 3.

図11に示す実施例も、スタッド7を外周縁部に取り付けた波形鋼板17を架構3の面内に嵌め入れて補強しているが、前記スタッド7を外周縁部に取り付けた波形鋼板17は単位波形鋼板6の外周上辺及び外周下辺の縁部にスタッド7を取り付けた構成としている(請求項及び請求項12記載の発明)。 The embodiment shown in FIG. 11 also reinforces the corrugated steel plate 17 with the stud 7 attached to the outer peripheral edge portion by fitting it into the surface of the frame 3, but the corrugated steel plate 17 with the stud 7 attached to the outer peripheral edge portion is Studs 7 are attached to the edges of the upper and lower outer peripheries of the unit corrugated steel sheet 6 (inventions according to claims 9 and 12 ).
