本発明は、水切り部材、水切り部材の設置システム、および水切り部材の設置方法に関するものである。特に、たとえば橋梁や建物などの構造物の下面を伝って流れようとする雨水を止めて重力方向に案内し落下させるための水切り部材と、この水切り部材を構造物の下面に設置するためのシステム、および水切り部材を構造物の下面に設置するための方法に関するものである。 The present invention relates to a draining member, a draining member installation system , and a draining member installation method. Particularly, for example, a draining member for stopping rainwater flowing along the lower surface of a structure such as a bridge or a building, guiding it in the direction of gravity and dropping it, and a system for installing this draining member on the lower surface of the structure. , And a method for installing a draining member on the underside of a structure.
構造物としてたとえば、橋梁の橋脚等の下部構造や、主桁、床版は、一般に鉄筋コンクリートなどにより構成されている。これ等の表面を雨水が流れることによって、表面に露出したコンクリートが腐食し、また内部の鉄筋等の金属構造材の酸化を促進する。そのため、これらの構造物の表面の特に張り出し部の下面を伝って流れようとする雨水を止めて重力方向に案内し落下させる水切り部材を構造物の下面に設置することが従来から行われている。水切り部材に関連する従来の技術として、たとえば特許文献１、２が知られている。 As a structure, for example, a substructure such as a bridge pier, a main girder, and a floor slab are generally made of reinforced concrete. The flow of rainwater on these surfaces corrodes the concrete exposed on the surface and accelerates the oxidation of metal structural materials such as internal reinforcing bars. Therefore, it has been conventionally performed to install a draining member on the lower surface of the structure, which stops rainwater flowing along the surface of these structures, particularly the lower surface of the projecting portion, and guides it in the gravity direction to drop it. .. For example, Patent Documents 1 and 2 are known as conventional techniques related to the draining member.
特許文献１には、コンクリート製屋根や橋梁等の張出し部の裏面に、これを伝って流下する雨水と交差するように三角柱状の水切部材を接合した水切装置において、上記水切部材を可撓性材料から形成し、該水切部材の上記張出し部の裏面に対する接合面を幅方向中央が最も深くなるように内方にスムーズに抉って形成し、該接合面に開口部が狭く奥が広く形成された溝を長手方向に沿って設け、該溝および抉られた接合面に接着剤を充填しその接着剤を介して水切部材を張出し部の裏面に押し付け、抉られた接合面を可撓変形させて裏面との間に区画された接着材充填空間に真空密着作用を生じさせ、もって水切部材を接着剤を介して裏面に接合し、該接着剤の硬化後に上記溝内に嵌まり込んだ接着剤をアンカー部材としたことを特徴とするコンクリート製屋根あるいは橋梁等の水切装置が開示されている。そして、特許文献１には、水切り部材は、各側面（接合面、雨水案内面、および水切面）が内方にえぐれた三角柱形状に成形されていること、さらに、雨水案内面および水切面は、共に半径２０mm程度の円弧状の抉れ面となっており、互いに対称に成形されていることが記載されている。 Patent Document 1 discloses a draining device in which a draining member having a triangular prism shape is joined to the back surface of an overhanging portion of a concrete roof, a bridge, or the like so as to intersect rainwater flowing down along the draining member. It is made of a material, and a joint surface with respect to the back surface of the overhanging portion of the draining member is smoothly carved inward so that the center in the width direction is deepest, and the joint surface has a narrow opening and a wide back. Groove is provided along the longitudinal direction, and the groove and the jointed surface that have been gouged are filled with an adhesive, and the draining member is pressed against the back surface of the overhanging portion through the adhesive to flexibly deform the gouged joint surface. To cause a vacuum adhesion action in the adhesive filling space defined between the back surface and the back surface, thereby bonding the draining member to the back surface through the adhesive, and then bonding the adhesive into the groove after curing the adhesive. There is disclosed a drainer for a concrete roof or a bridge, which is characterized by using an agent as an anchor member. In Patent Document 1, the draining member is formed in a triangular prism shape in which each side surface (joint surface, rainwater guide surface, and drainage surface) is engraved inward, and further, the rainwater guide surface and the drainage surface are It is described that both are arc-shaped gouged surfaces having a radius of about 20 mm and that they are formed symmetrically to each other.
また、特許文献２には、上記露出面と係止手段を有して上記コンクリート部材に埋め込まれる本体部分と、上記本体部分がコンクリート部材に埋め込まれた後に上記露出面に取り付けられ、上記コンクリート部材の表面から突出する線状の突起物で形成された水切り手段とを備えることを特徴とする水切り部材が開示されている。そして、特許文献２には、水切り部材の水切り突起は、三角形の断面を有する線状の突起物であることが記載されている。 Further, in Patent Document 2, a main body portion having the exposed surface and a locking means and embedded in the concrete member, and the main body portion embedded in the concrete member and then attached to the exposed surface, the concrete member And a draining means formed of a linear projection protruding from the surface of the draining member. Further, Patent Document 2 describes that the draining protrusion of the draining member is a linear protrusion having a triangular cross section.
さらに、特許文献２には、コンクリート部材を形成する型枠の内側面に、上記コンクリート部材の表面と同一平面を成して露出する平面により形成された露出面と、上記コンクリート部材に埋め込まれる埋設部分に設けられてコンクリートに係止する係止手段とを有して樹脂で形成された水切り部材を、上記露出面が型枠の内側面に接するように、この露出面を型枠の内側面に直接固定する型枠設置工程と、上記型枠の内側にコンクリートを打設する打設工程と、上記型枠をコンクリート部材から除去する脱型工程とを備えることを特徴とする水切り構造の施工方法が開示されている。そして、特許文献２の段落００４６、図６（ｃ）には、床板の下側面から露出した本体部分の取付溝に対して、治具を用いて水切り部材の水切り突起の連結部を挿入し床板側に押し込み、連結部の嵌合突起を取付溝の嵌合溝に嵌合させ、水切り突起を本体部分に固定すると、水切り構造が完成することが記載されている。 Further, in Patent Document 2, an exposed surface formed by a plane that is exposed on the inner surface of a mold forming a concrete member in the same plane as the surface of the concrete member, and an embedding embedded in the concrete member. A draining member made of resin having locking means for locking concrete, the exposed surface of the draining member being in contact with the inner surface of the mold; Construction of a draining structure characterized by including a formwork setting step of directly fixing to the mold, a placing step of placing concrete inside the formwork, and a demolding step of removing the formwork from a concrete member. A method is disclosed. Then, in paragraph 0046 of FIG. 6(c) of Patent Document 2, the connecting portion of the draining projection of the draining member is inserted into the mounting groove of the main body portion exposed from the lower surface of the floor plate by using the jig to insert the connecting portion of the draining member into the floor plate. It is described that the water draining structure is completed by pushing the draining protrusions to the side, fitting the fitting protrusions of the connecting portion into the fitting grooves of the mounting groove, and fixing the draining protrusions to the main body portion.
上記特許文献１、２には、水切り部材をポリ塩化ビニル（ＰＶＣ）、あるいは天然ゴム等の樹脂により構成することが開示されている。そして、特許文献２には、樹脂で形成された水切り部材が従来のコンクリート製の水切りブロックよりも軽量であることも記載されている。 The above Patent Documents 1 and 2 disclose that the drain member is made of polyvinyl chloride (PVC) or a resin such as natural rubber. Patent Document 2 also describes that the draining member made of resin is lighter in weight than a conventional concrete draining block.
特許文献２に記載されているように、従来のコンクリート製の水切りブロックよりも軽量である樹脂で形成された水切り部材を採用しても、かかる水切り部材を構成する樹脂が、内部に気泡を有しない中実の非発泡体であれば、発泡体により構成された水切り部材と比較して、重くなる。そのため、水切り部材をより軽量化するため、水切り部材を発泡体により構成することが考えられる。しかしながら、上記特許文献１、２に記載されているように断面三角形状に成形する水切り部材は、各角部の厚さが薄い形状となる。特に、特許文献１においては、各側面が内方に抉れた三角柱形状に成形されているため、各側面の側縁となる角部近傍の厚みが薄くなる。一方、内部に気泡を有する発泡体は、内部に気泡を有しない中実の非発泡体と比較して、一般に強度が低下する傾向にある。そのため、ただ単に、断面三角形状に成形する水切り部材を発泡体により構成すると、構造物の張り出し部の下面を伝って流れようとする雨水の流れや風などによって破損し易くなる。したがって、上記特許文献１、２に記載されているように断面三角形状に成形する水切り部材を発泡体により構成することが困難であることから、従来の技術では強度を低下させることなく水切り部材のさらなる軽量化を図ることができないという問題があった。 As described in Patent Document 2, even if a draining member formed of a resin that is lighter than a conventional concrete draining block is used, the resin forming the draining member has bubbles inside. If it is a solid non-foamed body, it becomes heavier than a draining member made of a foamed body. Therefore, in order to further reduce the weight of the draining member, it is considered that the draining member is made of foam. However, as described in Patent Documents 1 and 2 described above, the draining member formed in a triangular cross section has a shape in which each corner has a small thickness. In particular, in Patent Document 1, since each side surface is formed into a triangular prism shape in which each side surface is carved inward, the thickness in the vicinity of the corner portion which is the side edge of each side surface is thin. On the other hand, a foamed product having bubbles inside generally tends to have lower strength as compared with a solid non-foamed product having no bubbles inside. Therefore, if the draining member formed in a triangular shape in cross section is simply made of foam, the draining member is easily damaged by the flow of rainwater or wind flowing along the lower surface of the projecting portion of the structure. Therefore, since it is difficult to form the draining member formed in the triangular cross-section as described in Patent Documents 1 and 2 from the foam, the conventional technique does not reduce the strength of the draining member. There is a problem that it is not possible to further reduce the weight.
本発明は、上述した課題に鑑みてなされたもので、強度を低下させることなく非発泡体と比較して軽量である発泡体により構成することができ、もってさらに軽量化を図ることができる水切り部材を提供することを目的とする。
また本発明は、上述した課題に鑑みてなされたもので、水切り部材の接合面に接着剤を容易に塗布することができるとともに、構造物の張り出し部の下面に水切り部材を容易に接合させ設置することができるシステム、および方法を提供することを目的とする。
The present invention has been made in view of the above-mentioned problems, and can be configured with a foam that is lighter than a non-foamed body without reducing the strength, and thus a drainer that can further reduce the weight. It is intended to provide a member.
Further, the present invention has been made in view of the above-mentioned problems, and the adhesive can be easily applied to the joint surface of the draining member, and the drainer member can be easily joined to the lower surface of the projecting portion of the structure and installed. It is an object of the present invention to provide a system and a method capable of doing.

まず最初に、本発明の水切り部材１０を設置する構造物の一例として、橋梁の概略の構造を図１に基づいて説明する。 First, a schematic structure of a bridge will be described based on FIG. 1 as an example of a structure in which the draining member 10 of the present invention is installed.
図１に示した橋梁は、床版１の側縁が橋脚２から張り出しており、かかる張り出し部３の下面は、床版１の端縁から橋脚２に向かって下降するように傾斜している。本実施の形態では、床版１の張り出し部３の下面に、線条体に成形された水切り部材１０を床版１の側縁に沿って設置する。なお、本発明において水切り部材１０を設置する対象は、橋梁の床版１の張り出し部３の下面に特に限定されることはなく、主桁、横桁、橋台あるいは橋脚の梁等の張り出し部や、橋梁以外のたとえば建物の張り出し部の下面にも設置することができる。また、水切り部材を設置する対象の材質も特に限定されることはなく、鉄筋コンクリートやＰＣコンクリート以外のたとえば鋼材等の張り出し部の下面にも設置することができる。 In the bridge shown in FIG. 1, the side edge of the floor slab 1 projects from the bridge pier 2, and the lower surface of the projecting portion 3 is inclined so as to descend from the edge of the floor slab 1 toward the bridge pier 2. .. In the present embodiment, the draining member 10 formed into a linear body is installed on the lower surface of the overhanging portion 3 of the floor slab 1 along the side edge of the floor slab 1. In addition, the object to install the draining member 10 in the present invention is not particularly limited to the lower surface of the overhanging portion 3 of the floor slab 1 of the bridge, and the overhanging portion of the main girder, the lateral girder, the abutment or the beam of the pier, or the like. It can also be installed on the lower surface of the projecting part of the building other than the bridge. The material to which the draining member is installed is not particularly limited, and the draining member can be installed on the lower surface of the overhanging portion other than reinforced concrete or PC concrete, such as steel.
水切り部材１０は、可撓性を有する発泡体を線条体に成形してなるもので、表面全体が内部の気泡を露出させることなく、平滑となっている。図２に断面図で示すように、水切り部材１０は、張り出し部３の下面に接合される接合面２０を有する基部１１と、基部１１から接合面２０に対して鉛直に延びる壁部１２とを含んでいる。そして、本実施の形態における水切り部材１０は、基部１１の接合面２０の幅方向（図２の左右方向）中央を通る中心線Ｃ−Ｃに対して対称に成形されている。このように線条体の水切り部材１０を中心線Ｃ−Ｃに対して対称に成形することにより、水切り部材１０の向きを考慮する必要がなく設置することができる。しかしながら、水切り部材１０を設置する場所等により水切り部材１０の向きを考慮する必要がなければ、中心線Ｃ−Ｃに対して対称に成形しなくてもよい場合もある。 The draining member 10 is formed by forming a flexible foam into a linear body, and the entire surface is smooth without exposing air bubbles inside. As shown in the cross-sectional view of FIG. 2, the draining member 10 includes a base portion 11 having a joint surface 20 joined to the lower surface of the projecting portion 3 and a wall portion 12 extending vertically from the base portion 11 to the joint surface 20. Contains. The draining member 10 in the present embodiment is formed symmetrically with respect to the center line C-C passing through the center of the joint surface 20 of the base portion 11 in the width direction (left-right direction in FIG. 2 ). By forming the water draining member 10 of the linear body symmetrically with respect to the center line C-C in this manner, it is possible to install the draining member 10 without considering the direction of the water draining member 10. However, if it is not necessary to consider the orientation of the draining member 10 depending on the place where the draining member 10 is installed, it may not be necessary to form the draining member 10 symmetrically with respect to the center line C-C.
基部１１は、その接合面２０に対して直交する方向に所定の厚さＴａを有しており、その両側縁には側壁２１がそれぞれ形成されている。側壁２１は、接合面２０との間のなす角が鋭角となるよう傾斜している。基部１１が厚さＴａを有しており、側壁２１が接合面２０に対して鋭角となるなす角で傾斜していることにより、張り出し部３の下面を橋脚２に向かって流れる雨水を基部１１の側壁２１で止めて下方（重力方向）に落下させることができる。また、基部１１の接合面２０は、その幅方向中央に主溝２２が形成されており、主溝２２は、その開口部の幅Ｗａが狭く、底部の幅Ｗｂが開口部の幅Ｗａよりも広く形成されている。主溝２２の接合面２０から底部までの深さをＤａとし、幅Ｗａが狭い開口部の深さをＤｂとする。主溝２２と接合面２０の両側縁との間には、それぞれ副溝２３が形成されている。副溝２３は、主溝２２と比較して幅Ｗｃが狭く、且つ主溝２２の開口部の深さＤｂよりも深さＤｃが浅く形成されており、その結果、副溝２３の断面積は主溝２２の断面積と比較して小さくなっている。 The base portion 11 has a predetermined thickness Ta in a direction orthogonal to the joint surface 20, and side walls 21 are formed on both side edges of the base portion 11. The side wall 21 is inclined so that an angle formed with the joint surface 20 is an acute angle. Since the base portion 11 has a thickness Ta and the side wall 21 is inclined at an acute angle with respect to the joint surface 20, rainwater flowing toward the pier 2 on the lower surface of the overhanging portion 3 can be prevented. It can be stopped at the side wall 21 and dropped downward (in the direction of gravity). Further, the joint surface 20 of the base portion 11 has a main groove 22 formed in the center in the width direction thereof. The main groove 22 has a narrow opening width Wa and a bottom width Wb smaller than the opening width Wa. Widely formed. The depth of the main groove 22 from the joint surface 20 to the bottom is Da, and the depth of the opening having a narrow width Wa is Db. Sub-grooves 23 are formed between the main groove 22 and both side edges of the joint surface 20, respectively. The width Wc of the sub groove 23 is narrower than that of the main groove 22, and the depth Dc is formed shallower than the depth Db of the opening of the main groove 22. As a result, the cross-sectional area of the sub groove 23 is small. It is smaller than the cross-sectional area of the main groove 22.
壁部１２は、基部１１の側壁２１から角部１３を介して連続し先端部１２ａに向かって厚みが次第に減少するよう断面が所定の曲率で形成された曲部３０と、曲部３０から連続し先端部１２ａに向かって断面が一定の厚さＴｂで延びるよう直線状に形成される直線部３１と、を含んでいる。ここで、壁部１２の角部１３と先端部１２ａとの間の中心線Ｃ−Ｃと平行な長さ（壁部１２全体の高さ）をＨａとする。曲部３０の曲率半径Ｒは、壁部の全体の高さの５０〜７０％の寸法に設定することができる。このように曲部３０の曲率半径Ｒを設定することにより、壁部１２の厚さＴｂと相まって、発泡体からなる水切り部材の強度を低下させることなく、基部１１の側壁２１から角部１３を超えて流れる雨水を壁部１２の直線部３１に適切に導いて下方（重力方向）に落下させることができる。また、壁部１２の全体の高さＨａは、基部１１の傾斜した側壁２１を仮想上で延長させた仮想延長線Ｖよりも下方に先端部１２ａが位置するよう設定されている。このように壁部１２の全体の高さＨａを設定することにより、基部１１の側壁２１に衝突して跳ねた雨水が橋脚２側に向かって側壁部１２を超えるのを防止することができる。 The wall portion 12 is continuous from the side wall 21 of the base portion 11 through the corner portion 13 and has a curved portion 30 whose cross section is formed with a predetermined curvature so that the thickness gradually decreases toward the distal end portion 12a. And a linear portion 31 which is linearly formed so that its cross section extends toward the tip portion 12a with a constant thickness Tb. Here, the length (height of the entire wall portion 12) parallel to the center line C-C between the corner portion 13 of the wall portion 12 and the tip portion 12a is Ha. The radius of curvature R of the curved portion 30 can be set to 50 to 70% of the total height of the wall portion. By setting the radius of curvature R of the curved portion 30 in this manner, the corner portion 13 is removed from the side wall 21 of the base portion 11 without reducing the strength of the draining member made of foam in combination with the thickness Tb of the wall portion 12. It is possible to properly guide the rainwater flowing over to the straight portion 31 of the wall portion 12 and drop it downward (in the direction of gravity). Further, the overall height Ha of the wall portion 12 is set so that the tip portion 12a is located below a virtual extension line V obtained by virtually extending the inclined side wall 21 of the base portion 11. By setting the overall height Ha of the wall portion 12 in this manner, it is possible to prevent rainwater that has collided against the side wall 21 of the base portion 11 and splashed over the side wall portion 12 toward the pier 2 side.
ここで、水切り部材１０の各寸法の一例を述べる。水切り部材１０の長手方向の長さは１０００ｍｍとし、基部１１の接合面２０の幅方向の寸法Ｗは２５ｍｍで、厚さＴａが５ｍｍに設定されている。また、主溝２２の開口部の幅Ｗａは３ｍｍで、底部の幅Ｗｂは６ｍｍで形成されている。側壁２１と接合面２０との間のなす角は、５９〜６１°で、この実施の形態では６０°に設定されている。主溝２２の接合面２０から底部までの深さＤａは４ｍｍで、幅Ｗａが狭くなっている開口部の深さＤｂは２ｍｍである。副溝２３の深さＤｃは１ｍｍである。また、壁部１２の直線部３１の厚さＴｂは３ｍｍである。水切り部材１０の全体の高さ、すなわち接合面２０から壁部１２の先端部１２ａまでの中心線Ｃ−Ｃに沿った長さＨは２０ｍｍであり、壁部１２全体の高さＨａは１５ｍｍである。そして、壁部１２の曲部３０の曲率半径は、壁部１２全体の高さＨａの５０〜７０％が７．５〜１０．５ｍｍとなり、本実施の形態では９ｍｍに設定されている。 Here, an example of each dimension of the draining member 10 will be described. The length of the draining member 10 in the longitudinal direction is 1000 mm, the width W of the joint surface 20 of the base 11 is 25 mm, and the thickness Ta is 5 mm. The width Wa of the opening of the main groove 22 is 3 mm, and the width Wb of the bottom is 6 mm. The angle formed between the side wall 21 and the joint surface 20 is 59 to 61°, and is set to 60° in this embodiment. The depth Da from the joint surface 20 to the bottom of the main groove 22 is 4 mm, and the depth Db of the opening where the width Wa is narrow is 2 mm. The depth Dc of the sub groove 23 is 1 mm. Further, the thickness Tb of the straight portion 31 of the wall portion 12 is 3 mm. The overall height of the draining member 10, that is, the length H along the center line C-C from the joint surface 20 to the tip portion 12a of the wall portion 12 is 20 mm, and the height Ha of the entire wall portion 12 is 15 mm. is there. The radius of curvature of the curved portion 30 of the wall portion 12 is 7.5 to 10.5 mm at 50 to 70% of the height Ha of the entire wall portion 12, and is set to 9 mm in the present embodiment.
本発明の水切り部材１０は、可撓性を有する発泡体からなり、線条体に成形することができるものであれば、特に限定されることはなく、素材としてたとえば合成樹脂からなる発泡体や発泡ゴム（ゴムスポンジ）を採用することができる。そして、たとえば、合成樹脂の素材は、ポリエチレンやポリプロピレン等のポリオレフィンの他に、ポリスチレン、ポリウレタン、ポリ塩化ビニルを用いることができ、また、発泡ゴムの素材は、天然ゴムや、ＥＰＤＭ等の合成ゴムを用いることができる。また、水切り部材１０は、保持具５１の上辺５１ａ（後述する）で押圧した際に、弾性変形し得るものでもよく、また、硬質ものであってもよい。 The draining member 10 of the present invention is not particularly limited as long as it is made of a flexible foam and can be formed into a filament, and a foam made of, for example, a synthetic resin or Foamed rubber (rubber sponge) can be adopted. For example, the synthetic resin material may be polystyrene, polyurethane, or polyvinyl chloride in addition to polyolefin such as polyethylene or polypropylene, and the foam rubber material may be natural rubber or synthetic rubber such as EPDM. Can be used. Further, the draining member 10 may be elastically deformable when pressed by the upper side 51a (described later) of the holder 51, or may be hard.
次に、本発明の、上述したように構成された水切り部材１０を橋梁等の構造物の張り出し部３の下面に設置するためのシステムを構成する設置用治具５０の実施の一形態を、図３〜図４に基づいて説明する。 Next, an embodiment of an installation jig 50 that constitutes a system for installing the draining member 10 configured as described above on the lower surface of the projecting portion 3 of a structure such as a bridge of the present invention will be described. A description will be given based on FIGS. 3 to 4.
本発明の水切り部材１０の設置用治具５０は、基部１１の接合面２０を上方に向けて保持する保持具５１と、保持具５１を着脱可能に支持する支持台５２とを備えている。 The installation jig 50 for the draining member 10 of the present invention includes a holder 51 that holds the joint surface 20 of the base 11 upward, and a support base 52 that detachably supports the holder 51.
図３に示すように、保持具５１は、水切り部材１０の壁部１２を収容して、水切り部材１０の長手方向に沿って基部１１の下面または壁部１２の曲部３０に当接する上辺５１ａを有する断面コ字状に成形されたもので、線条体に成形された水切り部材１０の長さとほぼ同じ長さを有している。このような形状の保持具５１は、たとえば金属製板材を長手方向に沿って折り曲げるなどして成形することができる。一方、支持台５２は、図４並びに図５に示すように、この実施の形態では略三角柱を横置きにした形状であり、頂縁部に切り欠き６２が穿設されている。このような形状の支持台５２を形成する場合、矩形の金属製板材の一方端に差し込み部６０を形成すると共に、差し込み部６０を差し込むことができる孔または凹部６１を他方端近傍に形成し、また、後述するようにかかる板材を側面視で三角形状に折り曲げて孔または凹部６１に差し込み部６０を差し込んだときに頂縁となる部分に保持具５１を着脱可能に嵌合することができる切り欠き６２を形成しておく。そして、一対の支持台５２を適当な間隔をおいて配置し、断面コの字状の保持具５１をその開放部が上方に向く状態で各支持台５２の切り欠き６２に嵌合することで、設置用治具５０は水切り部材１０の受け入れ準備状態となる。 As shown in FIG. 3, the holder 51 accommodates the wall portion 12 of the draining member 10 and contacts the lower surface of the base portion 11 or the curved portion 30 of the wall portion 12 along the longitudinal direction of the draining member 10 with an upper side 51a. Is formed in a U-shaped cross section and has a length substantially the same as the length of the draining member 10 formed in the linear body. The holder 51 having such a shape can be formed, for example, by bending a metal plate material along the longitudinal direction. On the other hand, as shown in FIGS. 4 and 5, the support base 52 has a shape in which a substantially triangular prism is placed horizontally in this embodiment, and a notch 62 is formed in the top edge portion. When forming the support base 52 having such a shape, the insertion portion 60 is formed at one end of the rectangular metal plate material, and the hole or recess 61 into which the insertion portion 60 can be inserted is formed near the other end, In addition, as will be described later, when the plate member is bent in a triangular shape in a side view and the insertion portion 60 is inserted into the hole or the concave portion 61, the holder 51 can be detachably fitted to the top edge portion. The notch 62 is formed. Then, the pair of support bases 52 are arranged at appropriate intervals, and the holder 51 having a U-shaped cross section is fitted into the notch 62 of each support base 52 with its open portion facing upward. The installation jig 50 is ready for receiving the draining member 10.
次に、本発明の、上述したように構成された設置容治具５０を用いて、上述したように構成された水切り部材１０を橋梁等の構造物の張り出し部３の下面に設置するための方法の実施の一形態を、図３〜図７に基づいて説明する。 Next, a method for installing the draining member 10 configured as described above on the lower surface of the projecting portion 3 of a structure such as a bridge using the installation container jig 50 configured as described above according to the present invention. An embodiment of the above will be described with reference to FIGS.
水切り部材１０を設置するに先立って、必要に応じて、構造物の張り出し部３の下面の、水切り部材１０が設置される箇所の汚れをディスクサンダーやブラシ等により取り除く。また、構造物の張り出し部３の下面の水切り部材を設置する箇所に接着を阻害するような段差などがある場合には、必要に応じて、かかる段差を予め不陸調整しておく。そして、水切り部材を設置する構造物の張り出し部が乾燥状態であることを確認するか、または、乾燥状態とする。 Prior to installing the draining member 10, if necessary, stains on the lower surface of the projecting portion 3 of the structure where the draining member 10 is installed are removed by a disc sander, a brush or the like. Further, if there is a step or the like on the lower surface of the projecting portion 3 of the structure where the draining member is installed, which obstructs adhesion, the step is adjusted in advance in advance as necessary. Then, it is confirmed that the projecting portion of the structure on which the draining member is installed is in a dry state or the structure is in a dry state.
水切り部材１０を設置するにあたり、最初に、図３および図４に示すように、保持具５１を支持台５２に支持させると共に、保持具５１に水切り部材１０を保持させる。支持台５２は、水切り部材１０を設置する現場の地面等に配置することができる。また、支持台５２は、保持具５１の端部近傍を支持するよう一対で配置することができる。水切り部材１０は、接合面２０が上方を向いた状態で保持具５１に保持されている。この状態で、図５に示すようにカートリッジ７０に入った接着剤７１を接合面２０に塗布する。接着剤７１は、接合面２０の表面に塗布されるだけでなく、主溝２２や副溝２３に充填される。接合面２０が上方を向いた状態で保持されるため、容易に且つ確実に接着剤７１を接合面２０に塗布することができる。 When installing the draining member 10, first, as shown in FIGS. 3 and 4, the holding tool 51 is supported by the support base 52, and the holding tool 51 holds the draining member 10. The support base 52 can be arranged on the ground or the like at the site where the draining member 10 is installed. Further, the support bases 52 can be arranged in a pair so as to support the vicinity of the ends of the holder 51. The draining member 10 is held by the holder 51 with the joint surface 20 facing upward. In this state, as shown in FIG. 5, the adhesive 71 contained in the cartridge 70 is applied to the joint surface 20. The adhesive 71 is not only applied to the surface of the joint surface 20, but is also filled in the main groove 22 and the sub groove 23. Since the bonding surface 20 is held in a state of facing upward, the adhesive 71 can be easily and reliably applied to the bonding surface 20.
続いて、接着剤７１が塗布された水切り部材１０を保持した状態の保持具５１を支持台５２から取り外し、かかる保持具５１を把持して、保持具５１の上辺５１ａを全長にわたって水切り部材１０の曲部３０（基部１１の下面）に当接させた状態で、張り出し部３の下面に対して水切り部材１０の基部１１の接合面２０を押し当てる（図６の矢印Ｆを参照）。このとき、接着剤７１が主溝２２と副溝２３に充填されているため、接着剤７１が硬化していないときであっても、水切り部材１０が落下しないように接合面２０を構造物の張り出し部３の下面に吸着させるよう作用し、かかる下面に水切り材１０の接合面２０を食い付かせて保持する。そして、本発明の水切り部材１０が発泡体により構成されており非常に軽いので、接着剤７１が硬化するまで仮止をする必要がなく、直ぐに次の水切り部材を設置するための工程を行うことができる。その結果、短時間で水切り部材１０を構造物の張り出し部３の下面に短時間で設置することができる。接着剤が硬化すると、図７に示すように、主溝２２の開口部の幅Ｗａが底部の幅Ｗｂよりも狭く形成されており、しかも、主溝２２の両側に副溝２３が形成されているので、接合面２０が構造物の張り出し部３の下面に確実かつ強固に接合される。 Subsequently, the holder 51 in a state of holding the water draining member 10 coated with the adhesive 71 is removed from the support base 52, and the holder 51 is gripped, and the upper side 51a of the holder 51 is extended over the entire length of the water draining member 10. The contact surface 20 of the base portion 11 of the draining member 10 is pressed against the lower surface of the overhanging portion 3 while being in contact with the curved portion 30 (the lower surface of the base portion 11) (see arrow F in FIG. 6 ). At this time, since the adhesive 71 is filled in the main groove 22 and the sub-groove 23, the joint surface 20 is structured so that the draining member 10 does not drop even when the adhesive 71 is not cured. It acts so as to be adsorbed to the lower surface of the overhanging portion 3, and the joint surface 20 of the draining material 10 bites against and is held by the lower surface. Since the draining member 10 of the present invention is made of foam and is very light, it is not necessary to temporarily fix the adhesive 71 until the adhesive 71 is cured, and immediately perform the step of installing the next draining member. You can As a result, the draining member 10 can be installed on the lower surface of the projecting portion 3 of the structure in a short time in a short time. When the adhesive is hardened, as shown in FIG. 7, the width Wa of the opening of the main groove 22 is formed narrower than the width Wb of the bottom thereof, and the sub grooves 23 are formed on both sides of the main groove 22. Therefore, the joint surface 20 is securely and firmly joined to the lower surface of the projecting portion 3 of the structure.
そして、可撓性を有する発泡体で線条体に成形された水切り部材１０を保持具５１に保持した状態で把持するので、接合面２０に塗布された接着剤７１を構造物の張り出し部３の下面に容易に押し当て、設置することができる。接合面２０を押し当てた後に保持具５１を下げれば、接合面２０に塗布された接着剤７１が構造物の張り出し部３の下面に貼り付いた水切り部材１０から保持具５１が離れることとなる。 Then, since the draining member 10 formed into a linear body with a flexible foam is held by the holding tool 51, the adhesive 71 applied to the joint surface 20 is applied to the projecting portion 3 of the structure. It can be easily pressed against the lower surface of the and installed. When the holder 51 is lowered after pressing the joint surface 20, the holder 71 is separated from the draining member 10 in which the adhesive 71 applied to the joint surface 20 is attached to the lower surface of the projecting portion 3 of the structure. ..
なお、接着剤７１は、特に限定されることはないが、エポキシ樹脂系のコーキング材を採用することができる。また、接着剤を塗布する量は、水切り部材１ｍあたり４０〜４５ｇ程度とすることができる。 The adhesive 71 is not particularly limited, but an epoxy resin caulking material can be used. The amount of adhesive applied can be about 40 to 45 g per 1 m of the draining member.
