本発明は、補強板巻立て工法に係り、特に、利用高架橋や駅構内における耐震補強工事に用いるのに好適な、溶接やシール材によることなく、短い工期で、帯状補強板の接合部からの充填材の漏出を簡単且つ確実に防止することが可能な補強板巻立て工法に関する。 The present invention relates to a reinforcing plate winding method, and particularly suitable for use in seismic reinforcement work in use viaducts and station premises, without welding or sealing materials, and with a short construction period, from the joint portion of the belt-like reinforcing plate. The present invention relates to a reinforcing plate winding method capable of easily and reliably preventing leakage of a filler.
阪神淡路大震災や東日本大震災を契機に、コンクリート製の橋脚や柱の耐震性が再評価され、より耐震性を高めるための補強工事が行われている。橋脚等の補強工法の一つに鋼板巻立て工法がある。これは、柱状部分の周囲を囲むように鋼板を巻き立て、柱状部分と鋼板との間にモルタル等を注入して固定するものである。従来の鋼板巻立て工法では、柱状部分が矩形の場合、断面がコの字型の一対の鋼板を互いに向き合わせて柱状部分に嵌め込み、鋼板の対向する互いの端部に予め設けられた連結部材を介して連結している。しかしながら、この工法では、鋼板が大きなものとなり、クレーン車を用いて作業しなければならないため、クレーン車の入らないような狭い場所での作業はできない。 In the wake of the Great Hanshin-Awaji Earthquake and the Great East Japan Earthquake, the earthquake resistance of concrete piers and pillars has been reevaluated, and reinforcement work has been carried out to increase the earthquake resistance. One of the reinforcement methods for bridge piers is the steel sheet winding method. In this method, a steel plate is wound up so as to surround the periphery of the columnar portion, and mortar or the like is injected and fixed between the columnar portion and the steel plate. In the conventional steel sheet winding method, when the columnar part is rectangular, a pair of steel plates having a U-shaped cross section face each other and fit into the columnar part, and a connecting member provided in advance at the opposite ends of the steel sheet It is connected through. However, in this construction method, the steel plate becomes large, and it is necessary to work using a crane vehicle. Therefore, it is not possible to work in a narrow place where a crane vehicle cannot enter.
そこで、鋼板を縦方向に複数の帯状に分割して巻き立てる工法が案出された。更に、複数の帯状鋼板を縦方向に順次積み重ねて、見かけ上は１枚の鋼板のようにする工法も案出された。この工法は、下側の帯状鋼板の上端部内側に係止片を上向きに複数箇所溶接し、この係止片をガイドとして上側の帯状鋼板を下側の帯状鋼板の上に積み重ねるものであり、クレーン車の入らない狭い場所でも、作業員だけで巻立て作業ができる利点がある。 Accordingly, a method has been devised in which the steel sheet is divided into a plurality of strips in the longitudinal direction and wound up. Further, a method has been devised in which a plurality of strip steel plates are sequentially stacked in the vertical direction so that it looks like a single steel plate. This construction method is to weld a plurality of upward locking pieces on the inside of the upper end of the lower strip steel plate, and stack the upper strip steel plate on the lower strip steel plate with this locking piece as a guide, There is an advantage that only a worker can wind up even in a narrow place where a crane truck does not enter.
しかしながら、従来の帯状鋼板を用いた巻立て工法においては、縦方向に積み上げられた帯状鋼板の境目が不揃いになることがあり、モルタル注入時にその境目からの水漏れやモルタルのはらみが発生したり、美観が損なわれるという問題点があった。 However, in the conventional winding method using strip steel plates, the borders of the strip steel plates stacked in the vertical direction may become uneven, causing water leakage from the borders or mortar stagnation during mortar injection. There was a problem that aesthetics were impaired.
このような問題点を解決するものとして、特許文献１には、帯状鋼板の内側上端部に上向きに突出して溶接された複数の上向き係止片と、内側下端部に上向き係止片とは異なる位置に下向きに突出して溶接された複数の下向き係止片を設け、帯状鋼板同士の境目がきちんと突き合わされるようにして、モルタル注入時にその境目からの水漏れやモルタルのはらみ等の発生を防止することが記載されている。 In order to solve such a problem, Patent Document 1 discloses that a plurality of upward locking pieces that are protruded upward and welded to the inner upper end portion of the strip-shaped steel plate and different upward locking pieces at the inner lower end portion. Multiple downward locking pieces that protrude downward and are welded to the position so that the borders of the strip steel plates are properly abutted to prevent water leakage or mortar stagnation from the borders during mortar injection It is described to do.
しかしながら、特許文献１に記載の技術では、係止片の溶接作業が必要となるだけでなく、必ずしも十分にモルタルの漏れを防止することができないという問題点を有していた。 However, the technique described in Patent Document 1 has a problem in that not only does the operation of welding the locking pieces become necessary, but also mortar leakage cannot be prevented sufficiently.
なお、上下の帯状鋼板を（１）全周溶接したり、（２）スポット溶接した後、シール材を塗布したり、（３）シール材を塗布するだけという方法なども採られている。 In addition, the method of (1) all-around welding of an upper and lower strip | belt-shaped steel plate, (2) applying a sealing material after spot welding, or (3) applying only a sealing material etc. is also taken.
しかしながら、（１）全周溶接、又は（２）スポット溶接による接合では、（ｉ）駅構内や高架下利用箇所においては、火災や火災報知器の誤発報のリスクを伴う、（ii）火花から内装を保護するための周辺養生などに時間を要する、（iii）現場溶接は風の影響を受けやすく技術的に難しいため、溶接不良により、充填材が漏出する場合がある、などの問題点を有していた。 However, in (1) all-around welding or (2) spot welding, (i) there is a risk of fires or false alarms in places used under elevated stations, (ii) sparks It takes time to protect the interior from the surroundings, and (iii) On-site welding is susceptible to wind and technically difficult, so fillers may leak due to poor welding. Had.
又、（３）のシール材塗布のみによる場合は、（ｉ）エポキシ系などのシール材塗布後、硬化するまでの養生時間が必要となる、（ii）シール材の塗膜が薄いと、充填材が漏出する場合がある、などの問題点を有していた。 In addition, when only applying the sealing material of (3), (i) It takes time to cure after applying the sealing material such as epoxy, and (ii) Filling when the coating film of the sealing material is thin There was a problem that the material may leak.
本発明は、前記従来の問題点を解決するべくなされたもので、溶接やシール材によることなく、短い工期で、帯状補強板の接合部からの充填材の漏出を簡単且つ確実に防止できるようにすることを課題とする。 The present invention has been made to solve the above-mentioned conventional problems, and can easily and reliably prevent the leakage of the filler from the joint portion of the belt-like reinforcing plate in a short construction period without using welding or a sealing material. The challenge is to make it.
本発明は、補強対象に巻き立てられる帯状補強板を互いに接合した後、該帯状補強板と前記補強対象との間に充填材を充填する補強板巻立て工法において、前記帯状補強板の間に弾性体を挿入して、前記帯状補強板の接合部から前記充填材が漏れるのを防止するようにして、前記課題を解決したものである。 The present invention relates to a reinforcing plate winding method in which a band-shaped reinforcing plate wound around a reinforcing object is joined to each other and then a filler is filled between the band-shaped reinforcing plate and the reinforcing object, and an elastic body is provided between the band-shaped reinforcing plates. Is inserted to prevent the filler from leaking from the joint portion of the belt-shaped reinforcing plate.
ここで、前記弾性体がＵ型断面を有するものとし、その凹部を一方の帯状補強板に被せた後、その上に他方の帯状補強板を配設することができる。 Here, it is assumed that the elastic body has a U-shaped cross section, and after the concave portion is put on one band-shaped reinforcing plate, the other band-shaped reinforcing plate can be disposed thereon.
又、前記弾性体を、帯状のスポンジ系ゴムとすることができる。 The elastic body may be a band-like sponge rubber.
本発明によれば、溶接が不要となるため、火災のリスクを無くして、安全性を向上することができる。又、溶接やシール材塗布作業が不要となり、工期を短縮することができる。 According to the present invention, since welding is not necessary, the risk of fire can be eliminated and safety can be improved. Further, welding and sealing material application work are not required, and the construction period can be shortened.
以下、図面を参照して、本発明の実施の形態について詳細に説明する。なお、本発明は以下の実施形態及び実施例に記載した内容により限定されるものではない。又、以下に記載した実施形態及び実施例における構成要件には、当業者が容易に想定できるもの、実質的に同一のもの、いわゆる均等の範囲のものが含まれる。更に、以下に記載した実施形態及び実施例で開示した構成要素は適宜組み合わせてもよいし、適宜選択して用いてもよい。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited by the content described in the following embodiment and an Example. In addition, the constituent elements in the embodiments and examples described below include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those in the so-called equivalent range. Furthermore, the constituent elements disclosed in the embodiments and examples described below may be appropriately combined or may be appropriately selected and used.
本発明の実施形態は、図１にその基本的な構成を例示する如く、補強対象（図では柱）（以下、補強対象柱と称する）１０に巻き立てられる下層と上層の帯状補強鋼板１２、１４を互いに接合した後、該帯状補強鋼板１２、１４と補強対象柱１０の間にモルタル等の充填材２０を充填する補強鋼板巻立て工法において、下層帯状補強鋼板１２と上層帯状補強鋼板１４の間にゴム等の弾性体１６を挿入して、前記帯状補強鋼板１２と１４の接合部から充填材２０が漏出するのを防止するようにしたものである。 In the embodiment of the present invention, as illustrated in FIG. 1, the lower layer and the upper belt-shaped reinforcing steel plate 12 wound around a reinforcement object (column in the figure) (hereinafter referred to as a reinforcement object column) 10, In the reinforcing steel sheet winding method in which a filler 20 such as mortar is filled between the strip reinforcing steel plates 12 and 14 and the column 10 to be reinforced, the lower strip reinforcing steel plate 12 and the upper strip reinforcing steel plate 14 are joined together. An elastic body 16 such as rubber is inserted between them to prevent the filler 20 from leaking out from the joint between the belt-shaped reinforcing steel plates 12 and 14.
ここで、図１に例示したように補強対象が上下方向の柱１０である場合には、下層帯状補強鋼板１２と上層帯状補強鋼板１４の間に挿入した弾性体１６が上層帯状補強鋼板１４の重みで縮むため、充填材２０の漏出を十分に防止することができる。 Here, when the object to be reinforced is the column 10 in the vertical direction as illustrated in FIG. 1, the elastic body 16 inserted between the lower belt-like reinforcing steel plate 12 and the upper belt-like reinforcing steel plate 14 is Since the shrinkage is caused by the weight, leakage of the filler 20 can be sufficiently prevented.
次に、図２、図３Ａ及び図３Ｂを参照して、本発明の実施形態による補強鋼板巻立て工法の施工工程を説明する。 Next, with reference to FIG. 2, FIG. 3A and FIG. 3B, the construction process of the reinforcement steel plate winding method by embodiment of this invention is demonstrated.
まず、図２のステップ１００で、図３Ａ（ａ）に示す補強前の状態から、図３Ａ（ｂ）に示す如く、下層帯状補強鋼板１２を補強対象柱１０の周囲に巻き立てて、その垂直継手１２Ａを例えばボルト１２Ｂを用いた噛み合せ継手により接合する。なお、垂直継手１２Ａの接合方法は、耐震に必要な強度を持たせることができるのであれば、ボルトを用いた噛み合せ継手に限定されず、例えば噛み合せの無いボルト式継手であってもよい。 First, in step 100 of FIG. 2, from the state before reinforcement shown in FIG. 3A (a), as shown in FIG. The joint 12A is joined by, for example, a mesh joint using a bolt 12B. Note that the joining method of the vertical joint 12A is not limited to the meshing joint using bolts as long as the strength necessary for earthquake resistance can be given, and may be, for example, a bolt-type joint without meshing.
次いで図２のステップ１１０に進み、図３Ａ（ｃ）に示す如く、下層帯状補強鋼板１２の接合部上に弾性体１６を配置する。具体的には、下層帯状補強鋼板１２の接合部上に帯状の弾性体１６を一周させた後、端部を長めに切って突き合わせることができる。 Next, the process proceeds to step 110 in FIG. 2, and the elastic body 16 is disposed on the joint portion of the lower belt-shaped reinforcing steel plate 12 as shown in FIG. 3A (c). Specifically, after the belt-shaped elastic body 16 is made to make a round on the joint portion of the lower-layer belt-shaped reinforcing steel plate 12, the end portions can be cut long and abut each other.
次いでステップ１２０に進み、図３Ｂ（ｄ）に示す如く、弾性体１６上に上層帯状補強鋼板１４を設置する。 Next, the routine proceeds to step 120 where the upper-layer belt-shaped reinforcing steel sheet 14 is installed on the elastic body 16 as shown in FIG. 3B (d).
次いでステップ１３０に進み、図３Ｂ（ｅ）に示す如く、補強対象柱１０と帯状補強鋼板１２、１４の間にモルタル等の充填材２０を注入する。 Next, the routine proceeds to step 130, and as shown in FIG. 3B (e), a filler 20 such as mortar is injected between the reinforcing object column 10 and the belt-shaped reinforcing steel plates 12 and.
次いでステップ１４０に進み、図３Ｂ（ｆ）に示す如く、帯状補強鋼板１２、１４からはみ出した弾性体１６を切断するなど後処理して、補強工事を終了する。 Next, the routine proceeds to step 140, where as shown in FIG. 3B (f), post-treatment such as cutting the elastic body 16 protruding from the belt-shaped reinforcing steel plates 12, 14 is performed, and the reinforcement work is completed.
前記弾性体１６としては、例えば、工業用ゴム製品や建築用ゴム製品に幅広く使用されているエチレンプロピレンゴムを使用することができる。このエチレンプロピレンゴムは、耐候性、耐寒性、耐溶剤性などに優れており、様々な用途で使用されている。接着性や粘着性が乏しく、スポンジ系のゴムであるため、切断が容易である。 As the elastic body 16, for example, ethylene propylene rubber widely used in industrial rubber products and building rubber products can be used. This ethylene propylene rubber is excellent in weather resistance, cold resistance, solvent resistance and the like, and is used in various applications. Since it is a sponge rubber with poor adhesion and tackiness, it is easy to cut.
前記弾性体１６の断面形状について検討した。まず、図４（ａ）に示すような平板状である場合には、下層帯状補強鋼板１２上に配置した時に安定性が無いため、スプレーのりのような接着剤などで弾性体１６を固定する必要があった。 The cross-sectional shape of the elastic body 16 was examined. First, in the case of a flat plate shape as shown in FIG. 4A, the elastic body 16 is fixed with an adhesive such as a spray paste because it is not stable when placed on the lower belt-shaped reinforcing steel plate 12. There was a need.
また、図４（ｂ）に示すようなＨ型の場合には、下層帯状補強鋼板１２上に配置した時の安定性はあるが、弾性体１６の溝への上層帯状補強鋼板１４の嵌め込みが容易でないという問題点を有していた。 In addition, in the case of the H type as shown in FIG. 4B, there is stability when placed on the lower belt-like reinforcing steel plate 12, but the upper belt-like reinforcing steel plate 14 is fitted into the groove of the elastic body 16. There was a problem that it was not easy.
一方、図４（ｃ）に示すＵ型で、凹部を下側に向けた場合には、上層帯状補強鋼板１４が設置し易く、下層帯状補強鋼板１２上に配置した時の安定性があり良好であった。 On the other hand, in the U shape shown in FIG. 4 (c), when the concave portion is directed downward, the upper-layer belt-shaped reinforcing steel plate 14 is easy to install and is stable when placed on the lower-layer belt-shaped reinforcing steel plate 12. Met.
なお、図４（ｂ）のＨ型、図４（ｃ）のＵ型の場合には、外側にはみ出した弾性体１６を切断して見栄えを向上することが望ましい。 In the case of the H type shown in FIG. 4B and the U type shown in FIG. 4C, it is desirable to improve the appearance by cutting the elastic body 16 protruding outward.
又、図４（ｄ）に示すＬ型の場合には、外側の処理は不要であるが、下層帯状補強鋼板１２上に配置した時の安定性が無く、図４（ａ）の平板の場合と同様に固定が必要であった。 Further, in the case of the L type shown in FIG. 4 (d), outside processing is not required, but there is no stability when placed on the lower belt-shaped reinforcing steel sheet 12, and the case of the flat plate of FIG. 4 (a). Fixation was required as well.
以上の結果、図５に示す実施例のように、Ｕ型に弾性体１６を成形し、下層帯状補強鋼板１２に差し込む形で配置するのが最良であることが分かった。この場合には、弾性体１６を下層帯状補強鋼板１２に嵌め込むだけでよく、上層帯状補強鋼板１４の設置時にずれ落ちることが無い。 As a result, it has been found that it is best to form the elastic body 16 in a U shape and insert it into the lower belt-shaped reinforcing steel plate 12 as in the embodiment shown in FIG. In this case, it is only necessary to fit the elastic body 16 into the lower-layer belt-shaped reinforcing steel plate 12, and there is no slippage when the upper-layer belt-shaped reinforcing steel plate 14 is installed.
なお、前記弾性体１６の横断面形状に関しては、図６に示す如く、ｔ1＝５ｍｍ、ｔ2＝
１０ｍｍ、ｈ＝１０ｍｍである場合に、凹部の幅ｗを、例えば８ｍｍとすることにより、帯状補強鋼板１２、１４の板厚６ｍｍ〜１２ｍｍまで対応できることが確認できた。ここで、弾性体１６の凹部中央の上下方向厚みｔ2は、鋼板設置時の耐久性を確保できる厚みとし、弾性体１６の凹部両側の上下方向の高さｈは、鋼板設置時の安定性に応じて決めることができる。
As for the cross-sectional shape of the elastic body 16, as shown in FIG. 6, t 1 = 5 mm, t 2 =
In the case of 10 mm and h = 10 mm, it was confirmed that the thickness of the recess-shaped reinforcing steel plates 12 and 14 can be accommodated from 6 mm to 12 mm by setting the width w of the concave portion to 8 mm, for example. Here, the vertical thickness t 2 at the center of the concave portion of the elastic body 16 is set to a thickness that can ensure the durability when the steel plate is installed, and the vertical height h on both sides of the concave portion of the elastic body 16 is the stability when the steel plate is installed. Can be decided according to.
なお、前記実施形態においては、帯状補強板として鋼板が用いられていたが、帯状補強板の材質は鋼に限定されない。又、弾性体１６の材質もエチレンプロピレンゴムに限定されず、他のスポンジ系ゴムを用いることもできる。又、弾性体１６の横断面形状もＵ型に限定されず、図４（ｂ）に示したようなＨ型、図４（ａ）に示したような平板状、図４（ｄ）に示したようなＬ型や、他の形状であっても良い。 In the embodiment, a steel plate is used as the belt-like reinforcing plate, but the material of the belt-like reinforcing plate is not limited to steel. The material of the elastic body 16 is not limited to ethylene propylene rubber, and other sponge rubber can be used. Further, the cross-sectional shape of the elastic body 16 is not limited to the U shape, but is an H shape as shown in FIG. 4B, a flat shape as shown in FIG. 4A, and a shape shown in FIG. It may be an L shape or another shape.
更に、補強対象も柱に限定されず、高架橋や梁など斜め又は水平方向の補強対象にも適用できる。又、補強の目的も耐震補強に限定されない。 Furthermore, the object to be reinforced is not limited to a pillar, and can be applied to objects to be reinforced diagonally or horizontally such as viaducts and beams. The purpose of reinforcement is not limited to seismic reinforcement.
