Description

本発明は橋梁の地覆部における伸縮吸収用の遊間のシール構造、シール材並びにそのシール方法に関する。   TECHNICAL FIELD The present invention relates to a seal structure for absorbing expansion and contraction in a bridge covering portion, a sealing material, and a sealing method thereof.

橋梁では、温度変化の影響による橋の床版の伸縮吸収、耐震性向上のために床版や道路等を長手方向に直接剛結することなく各床版間に伸縮装置を介在させて遊間を形成した状態で施工されるのが通常である。遊間の上部で交通路の路面側に露出する部分は、該遊間を閉鎖被覆し、水分が橋の下部側に流下することによる橋土台や橋脚を含む橋梁の下部構造部のコンクリート腐食、鉄筋等金属構造材の酸化、耐久性低下等を防止するようにしている。一方、橋梁幅員の最端部すなわち道路橋の両端側に、自動車の視線誘導あるいは自動車が歩道部分や橋面外へ逸脱するのを防ぐために突起状の構造物である地覆部が道路の長手方向に沿って設置される。従来、床版間の遊間について、地覆部分については地覆部が路面から所要の高さで上方に突設しているので閉鎖被覆のためのシール作業が容易でなく、伸縮装置等の施工作業性を低下させる要因となっていた。地覆部分の遊間のシールに関して特許文献１の提案がなされている。   In bridges, in order to absorb expansion and contraction of bridge floor slabs due to the effect of temperature changes and improve seismic resistance, the floor slabs and roads are not directly rigidly connected in the longitudinal direction, but an extension device is interposed between the floor slabs to provide clearance. It is usually constructed in the formed state. The part exposed on the road surface side of the traffic road in the upper part of the gap is closed and covered with the gap, and the concrete corrosion of the lower structure part of the bridge including the bridge foundation and bridge piers due to the water flowing down to the lower side of the bridge, reinforcing bars, etc. The metal structure material is prevented from being oxidized and deteriorated in durability. On the other hand, at the extreme end of the bridge width, that is, at both ends of the road bridge, the ground cover, which is a projecting structure, is used to guide the line of sight of the vehicle or prevent the vehicle from deviating from the sidewalk or the bridge surface. Installed along the direction. Conventionally, as for the gap between floor slabs, since the ground cover part protrudes upward at the required height from the road surface, the sealing work for the closure covering is not easy and the construction of the expansion device etc. It was a factor that lowered workability. Patent Document 1 proposes a seal between play of the ground cover portion.

In the embodiment, as shown in FIG. The deformed portion 14 is formed of a rectangular parallelepiped rod-like member having a substantially square cross section having the same side as the short side length of the long plate. One side of the rectangular parallelepiped second elastic deformation portion 16 is joined to one plate surface of the first elastic deformation portion 14 so that the first and second elastic deformation portions 14 and 16 are integrated. The second elastic deformation portion 16 is thicker in terms of the size in the thickness direction of the first elastic deformation portion. The other plate surface 161a side of the second elastic deforming portion 16 facing the joint portion with the first elastic deforming portion 14 is impacted against the other end wall 401b (401a) of the ground covering portion when fitted into the play gap p. The contact gap p is sealed. The second elastic deformation portion 16 has a property of being deformed by receiving an external force, and is an elastic deformation member that is more easily elastically deformed than the first elastic deformation portion 14. Easily elastically deforms. In the embodiment, the second elastic deformation portion 16 is formed of a water-impermeable sponge material. Non-water-permeable sponge material is a porous soft material with countless fine pores inside, and has flexibility and great elasticity, and has the property of blocking water permeability. It is formed by foaming molding of resin.

第２弾性変形部１６は、第１弾性変形部１４に一体接合され第１弾性変形部より弾性変形しやすい部位である。すなわち、第１弾性変形部１４は、第２弾性変形部１６より弾性変形しにくい素材で構成されそれぞれの変形部１４，１６が棒状に一体化されている。これにより、遊間ｐにシール材１２を挿嵌するときは、第２弾性変形部１６を圧縮させて体積を小さくした状態で遊間に押入れ、少しの位置調整をするだけで遊間のシール作業を完了することができる。シール材１２は遊間の外部側に近い部分のみに嵌着される態様としてもシール性が確保されておればよい。本実施形態では第１弾性変形部１４より第２弾性変形部１６は接合方向厚さを厚くしているが、第１弾性変形部１４のほうを第２弾性変形部１６より厚く形成することもできる。また、その厚さの具体的関係は任意に設定できる。また、第２弾性変形部１６にさらに他の弾性変形部を接合させることもできる。   The second elastic deformation portion 16 is a portion that is integrally joined to the first elastic deformation portion 14 and is more easily elastically deformed than the first elastic deformation portion. That is, the 1st elastic deformation part 14 is comprised with the raw material which is hard to elastically deform rather than the 2nd elastic deformation part 16, and each deformation | transformation parts 14 and 16 are integrated in rod shape. As a result, when the sealing material 12 is inserted into the gap p, the second elastic deformation part 16 is compressed and pushed into the gap in a state where the volume is reduced, and the sealing work between the gaps is completed by adjusting the position slightly. can do. The sealing material 12 should just ensure sealing performance also as an aspect fitted only in the part close | similar to the exterior side between play. In the present embodiment, the second elastic deformation portion 16 is thicker in the joining direction than the first elastic deformation portion 14. However, the first elastic deformation portion 14 may be formed thicker than the second elastic deformation portion 16. it can. Moreover, the specific relationship of the thickness can be set arbitrarily. Further, another elastic deformation portion can be joined to the second elastic deformation portion 16.

次に、本実施形態の地覆部の床版間遊間のシール構造の施工方法について説明する。非透水の第１弾性変形部１４と、第１弾性変形部より弾性変形しやすい非透水の第２弾性変形部１６と、を一体化した図２，３のような角棒状のシール部材１２を用意する。次に、第１弾性変形部１４の端壁１４１ａと、地覆部の一端壁４０１ａとに接着剤１８を塗着する。このとき、第１弾性変形部１４は、接着剤の塗着基板として簡単に接着剤を板面に塗着させることができる。この際、第１弾性変形部１４の端壁１４１ａ側にのみ接着剤１８を塗着してもよい。そして、対向地覆部端壁４０１ａ、４０１ｂ間に挟まれる遊間ｐ内にシール部材１２の第２弾性変形部１６を手などで圧縮した状態として狭小な隙間である遊間ｐ内にシール材全体を押し入れる。このとき、第１弾性変形部１４は、より弾性変形しやすい第２弾性変形部の支持基板として機能する。そして、シール部材１２の一端側である接着剤塗着面側を地覆部端壁に接着接合するとともに、シール部材１２の他端側を地覆部端壁１６１ａに圧接当着させることにより、遊間ｐをシールさせる。ここにおいて、第１弾性変形部１４は、遊間ｐへの挿嵌時の隙間への案内基板として機能する。そして、シール部材が遊間から地覆部の外郭形状を越えてはみ出さないように位置調整を行う。そして、図４に示すようにコ字状の外郭の地覆部８の上部と両側部について挿嵌設置作業を行う。第１弾性変形部１６は、第２弾性変形部より保形性が大きく第１弾性変形部より弾性変形しにくいから、シール材１２の遊間ｐへの挿嵌作業時には、第２弾性変形部１６を第１弾性変形部側に圧縮しながら第１弾性変形部をガイドとして遊間内に挿入し嵌合位置を設定できるからシール材施工作業を簡単かつ円滑、短時間、良好精度で完了させることができる。また、シールのための装置、部材コストを大幅に低減させることが可能である。   Next, the construction method of the seal structure between the floor slabs of the ground cover part of this embodiment will be described. A rectangular rod-like sealing member 12 as shown in FIGS. 2 and 3 is formed by integrating the first non-water-permeable first elastic deformation portion 14 and the non-water-permeable second elastic deformation portion 16 which is more easily elastically deformed than the first elastic deformation portion. prepare. Next, the adhesive 18 is applied to the end wall 141a of the first elastic deformation portion 14 and the one end wall 401a of the ground covering portion. At this time, the first elastic deformation portion 14 can easily apply the adhesive to the plate surface as an adhesive application substrate. At this time, the adhesive 18 may be applied only to the end wall 141 a side of the first elastic deformation portion 14. Then, the entire sealing material is placed in the gap p which is a narrow gap as the second elastic deformation portion 16 of the seal member 12 is compressed by hand in the gap p sandwiched between the opposing ground cover end walls 401a and 401b. Push in. At this time, the 1st elastic deformation part 14 functions as a support substrate of the 2nd elastic deformation part which is easier to elastically deform. And while adhesively bonding the adhesive coating surface side which is one end side of the seal member 12 to the ground cover end wall, by pressing the other end side of the seal member 12 to the ground cover end wall 161a, Seal the gap p. Here, the 1st elastic deformation part 14 functions as a guide board | substrate to the clearance gap at the time of insertion to the clearance gap p. Then, the position is adjusted so that the seal member does not protrude from the gap beyond the outline of the ground cover. And as shown in FIG. 4, insertion installation work is performed about the upper part and both sides of the ground cover part 8 of a U-shaped outer shape. Since the first elastic deformation portion 16 has a larger shape retaining property than the second elastic deformation portion and is less likely to be elastically deformed than the first elastic deformation portion, the second elastic deformation portion 16 is inserted when the sealing material 12 is inserted into the clearance p. Since the first elastic deformation portion can be inserted into the play space while the first elastic deformation portion is compressed to the first elastic deformation portion side and the fitting position can be set, the sealing material construction work can be completed easily, smoothly, in a short time with good accuracy. it can. Moreover, it is possible to significantly reduce the device for sealing and member costs.

上記の説明では、シール材１２は断面角形で直棒状の器具を用いる例を示したが、地覆部形状に対応して図５、図６に示すように、逆Ｌ形と直棒形（図５）、Ｌ形と直棒方（図６）のようなシール材を準備して地覆部遊間に設置してもよい。   In the above description, the sealing material 12 is an example in which a straight rod-shaped instrument having a square cross section is used. However, as shown in FIGS. 5 and 6 corresponding to the shape of the ground cover, an inverted L shape and a straight rod shape ( 5), sealing materials such as an L shape and a straight rod (FIG. 6) may be prepared and installed between the ground cover play.
