Description

本発明は、橋軸方向に沿って互いに隣り合うように配置される壁高欄同士を接合する構造に関する。   The present invention relates to a structure for joining wall rails arranged adjacent to each other along a bridge axis direction.

従来、橋軸方向に沿って互いに隣り合うように配置される壁高欄同士を接合する構造としては、互いに隣り合う一方の壁高欄の端面に溝を設けるとともに、互いに隣り合う他方の壁高欄の端面には前記溝内に挿入される継手を設け、当該溝内に継手を挿入した後に溝内にモルタルやコンクリート等の充填材を充填することにより、壁高欄同士を接合する構造が知られている（特許文献１参照）。
当該構造は、継手として孔あき鋼板ジベルを用い、壁高欄に加わる橋軸方向の引抜力及び橋軸直角方向の衝撃力に対して、接合部における孔あき鋼板ジベルのせん断抵抗により抵抗する構造となっている。 Conventionally, as a structure for joining wall rails arranged so as to be adjacent to each other along the bridge axis direction, a groove is provided in an end surface of one wall height column adjacent to each other, and an end surface of the other wall height column adjacent to each other Is known in which a joint to be inserted into the groove is provided, and the wall rails are joined by filling the groove with a filler such as mortar or concrete after the joint has been inserted into the groove. (See Patent Document 1).

しかしながら、上述した従来の接合構造では、継手としての孔あき鋼板ジベルが壁高欄の端面から突出するようにアンカー鋼材によって壁高欄の端部のコンクリート内に強固に固定されている。即ち、孔あき鋼板ジベルが壁高欄の端部のコンクリート内に埋め込まれている。
従って、壁高欄を取替える場合、接合部で切断すると孔あき鋼板ジベルを切断してしまって孔あき鋼板ジベルを使用できなくなるため、孔あき鋼板ジベルを避けて切断して、孔あき鋼板ジベルを斫り出す必要があり、壁高欄の取替え作業にかかる労力が甚大であるという問題点があった。
また、孔あき鋼板ジベルが変形してしまっていたら、当該孔あき鋼板ジベルが取り付けられていた壁高欄も取り替える必要があり、コスト面での問題点もあった。
本発明は、壁高欄に加わる橋軸方向の引抜力及び橋軸直角方向の衝撃力に対して十分に抵抗できるとともに、壁高欄の取替え作業の容易化及び低コスト化が図れる壁高欄同士の接合構造を提供するものである。 However, in the conventional joint structure described above, a perforated steel plate gibber as a joint is firmly fixed in the concrete at the end of the wall rail by an anchor steel material so as to protrude from the end surface of the wall rail. That is, a perforated steel plate gibber is embedded in the concrete at the end of the wall rail.
Therefore, when replacing the wall rails, if the perforated steel plate gibber is cut when it is cut at the joint, it becomes impossible to use the perforated steel plate gibel. There was a problem that the labor required to replace the wall rail was enormous.
In addition, if the perforated steel plate gibble has been deformed, it is necessary to replace the wall rail to which the perforated steel plate gibber was attached, and there was a problem in terms of cost.
The present invention can sufficiently resist the pulling force in the direction of the bridge axis applied to the wall rail and the impact force in the direction perpendicular to the bridge axis, and also makes it easy to replace the wall rail and reduce the cost. Provide structure.

本発明に係る壁高欄同士の接合構造は、橋軸方向に沿って目地間隔を介して互いに隣り合うように配置される各壁高欄の互いに対向する各端面において上下方向に延長するように形成されて互いに向かい合う各溝に板材が橋軸方向に沿って跨るように配置され、板材が配置された各溝内、及び、目地間隔内に充填材が充填されたことを特徴とするので、壁高欄に加わる橋軸方向の引抜力及び橋軸直角方向の衝撃力に対して十分に抵抗できるとともに、壁高欄の取替え作業の容易化及び低コスト化が図れる壁高欄同士の接合構造を提供できる。
また、板材は、板面に摩擦抵抗部を備えたので、引抜せん断抵抗が大きくなり、壁高欄に加わる橋軸方向の引抜力及び橋軸直角方向の衝撃力に対して十分に抵抗できるとともに、壁高欄の取替え作業の容易化及び低コスト化が図れる壁高欄同士の接合構造を提供できる。
また、摩擦抵抗部は、板材を貫通するように形成された複数の貫通孔、又は、板材の板面に形成された複数の凹部であり、各溝に配置された板材の各貫通孔内、又は、各凹部内に充填材が充填されたことを特徴とするので、貫通孔内、又は、各凹部内に充填された充填材のせん断抵抗によって橋軸方向の引抜力に抵抗する構造となり、壁高欄に加わる橋軸方向の引抜力及び橋軸直角方向の衝撃力に対して十分に抵抗できるとともに、壁高欄の取替え作業の容易化及び低コスト化が図れる壁高欄同士の接合構造を提供できる。
また、摩擦抵抗部は、板材の板面に当該板面より突出するように形成された複数の突起部であり、各溝に配置された板材の各突起部の周囲に充填材が充填されたことを特徴とするので、各突起部の周囲に充填された充填材のせん断抵抗によって橋軸方向の引抜力に抵抗する構造となり、壁高欄に加わる橋軸方向の引抜力及び橋軸直角方向の衝撃力に対して十分に抵抗できるとともに、壁高欄の取替え作業の容易化及び低コスト化が図れる壁高欄同士の接合構造を提供できる。
また、溝は、板材の橋軸方向の端部と対向する溝底面と、溝底面の橋軸直角方向における両端側から壁高欄の端面に到達する互いに対向する一対の溝内壁面とを備え、一対の溝内壁面は、壁高欄の端面に近付くに従って互いに近づくように形成されたことを特徴とするので、一対の溝内壁面によって充填材に対する拘束力が大きくなり、板材の引抜防止効果をさらに向上させることが可能となる。 The joint structure of the wall rails according to the present invention is formed so as to extend in the vertical direction at each end surface facing each other of the wall rails arranged so as to be adjacent to each other via a joint interval along the bridge axis direction. Since the plate material is arranged so as to straddle along the bridge axis direction in each groove facing each other, the filler is filled in each groove in which the plate material is arranged, and in the joint interval. It is possible to provide a joint structure between wall rails that can sufficiently resist the pulling force in the direction of the bridge axis and the impact force in the direction perpendicular to the bridge axis and that can facilitate the replacement work of the wall rails and reduce the cost.
In addition, since the plate material is provided with a friction resistance portion on the plate surface, the pulling shear resistance is increased, and it can sufficiently resist the pulling force in the bridge axis direction applied to the wall rail and the impact force in the direction perpendicular to the bridge axis, It is possible to provide a joint structure between wall rails that facilitates the replacement work of the wall rails and reduces costs.
Further, the friction resistance portion is a plurality of through holes formed so as to penetrate the plate material, or a plurality of concave portions formed on the plate surface of the plate material, and in each through hole of the plate material arranged in each groove, Or, since it is characterized in that each recess is filled with a filler, it becomes a structure that resists the pulling force in the bridge axis direction by the shear resistance of the filler filled in the through hole or each recess, It is possible to provide a joint structure between wall rails that can sufficiently resist the pulling force in the direction of the bridge axis applied to the wall rails and the impact force in the direction perpendicular to the bridge axis, and that can facilitate replacement of the wall rails and reduce costs. .
Further, the frictional resistance portion is a plurality of protrusions formed on the plate surface of the plate material so as to protrude from the plate surface, and a filler is filled around each protrusion portion of the plate material arranged in each groove. Therefore, it becomes a structure that resists the pulling force in the direction of the bridge axis by the shear resistance of the filler filled around each protrusion, and the pulling force in the direction of the bridge axis applied to the wall rail and the direction perpendicular to the bridge axis It is possible to provide a joint structure between wall rails that can sufficiently resist an impact force and that can facilitate replacement of the wall rails and reduce costs.
Further, the groove comprises a groove bottom surface facing the end portion in the bridge axis direction of the plate material, and a pair of groove inner wall surfaces facing each other reaching the end surface of the wall rail from both ends in the direction perpendicular to the bridge axis of the groove bottom surface, Since the pair of groove inner wall surfaces are formed so as to approach each other as they approach the end surface of the wall rail, the pair of groove inner wall surfaces increase the binding force on the filler, further enhancing the effect of preventing the plate material from being pulled out. It becomes possible to improve.

実施形態１に係る壁高欄同士の接合構造は、図１に示すように、複数の床版を敷設して構成された床部４における橋軸直角方向Ｙの両端側の上面において、各壁高欄１，１を橋軸方向Ｘに沿って目地間隔５を介して互いに隣り合うように配置し、隣り合う各端面２，２に形成された各溝３，３に跨るように孔空き平板材としての孔空き鋼板６を設置し、溝３，３内、及び、目地間隔５内にモルタルやコンクリート等の充填材７を充填することにより、当該各溝３，３に跨るように設置された孔空き鋼板６と、当該溝３，３内、及び、目地間隔５内に充填された充填材７とによって、橋軸方向Ｘに沿って互いに隣り合うように配置された一方の壁高欄１と他方の壁高欄１とが接合された構造である。
尚、孔空き鋼板６は、例えば、図１に示すように、橋軸方向Ｘに沿って目地間隔５を介して互いに隣り合うように配置される各壁高欄１，１の互いに対向する各端面２，２において上下方向に延長するように形成されて互いに向かい合う各溝３，３に跨るように配置される板である。このように孔空き鋼板６が各溝３，３に跨るように配置された場合、孔空き鋼板６は、橋軸方向Ｘに沿った方向の長さが、当該互いに向かい合う各溝３，３に跨って、かつ、各溝３，３の互いに向い合う溝底面３１，３１間の距離よりも若干短い寸法に形成されるとともに、上下方向Ｚに沿った方向の長さが、溝３の上下方向Ｚに沿った方向の長さよりも若干短い寸法に形成され、かつ、板厚が十数ｍｍ程度（例えば１３ｍｍ）の平板に形成された矩形鋼板に、板面を貫通する貫通孔６１が複数個形成された構成である。当該孔空き鋼板６が互いに向かい合う各溝３，３に跨るように配置された場合に、複数の貫通孔６１，６１…は、橋軸方向Ｘ及び橋軸直角方向Ｙに沿って所定の間隔を隔てて存在することになるように形成されている。例えば、孔空き鋼板６は、互いに向かい合う各溝３，３に跨るように配置された場合に、各溝３内において、それぞれ上下方向Ｚに沿って所定間隔を隔てて複数個の貫通孔６１，６１…が位置されるように構成されている。尚、貫通孔６１の直径は例えば４０ｍ〜６０ｍｍ程度に形成される。 As shown in FIG. 1, the joint structure between the wall rails according to the first embodiment is formed on the upper surfaces of both ends in the direction Y perpendicular to the bridge axis in the floor portion 4 constructed by laying a plurality of floor slabs. 1 and 1 are arranged so as to be adjacent to each other along the bridge axis direction X with a joint interval 5 between them, and as a perforated flat plate material so as to straddle the grooves 3 and 3 formed in the adjacent end faces 2 and 2. Are installed so as to straddle the grooves 3 and 3 by filling the grooves 3 and 3 and the filler 7 such as mortar or concrete in the joint intervals 5. One wall height column 1 and the other arranged adjacent to each other along the bridge axis direction X by the empty steel plate 6 and the filler 7 filled in the grooves 3 and 3 and the joint interval 5 The wall height column 1 is joined.
In addition, as shown in FIG. 1, for example, as shown in FIG. 1, the perforated steel plates 6 are end faces facing each other of the wall height columns 1 and 1 arranged so as to be adjacent to each other via the joint interval 5 along the bridge axis direction X. The plate is formed so as to extend in the vertical direction at 2 and 2 and is disposed so as to straddle the grooves 3 and 3 facing each other. When the perforated steel plate 6 is arranged so as to straddle the grooves 3 and 3 in this way, the perforated steel plate 6 has a length in the direction along the bridge axis direction X in the grooves 3 and 3 facing each other. The groove 3 is formed to have a dimension slightly shorter than the distance between the groove bottom surfaces 31 and 31 facing each other, and the length in the vertical direction Z is the vertical direction of the groove 3. A plurality of through-holes 61 penetrating the plate surface are formed in a rectangular steel plate formed in a flat plate having a thickness slightly shorter than the length in the direction along Z and a plate thickness of about a dozen mm (for example, 13 mm). It is the formed structure. When the perforated steel plates 6 are arranged so as to straddle the grooves 3 and 3 that face each other, the plurality of through holes 61, 61... Have a predetermined interval along the bridge axis direction X and the bridge axis perpendicular direction Y. It is formed so as to exist apart. For example, when the perforated steel plate 6 is disposed so as to straddle the grooves 3 and 3 that face each other, the plurality of through holes 61 and 61... Are positioned. Note that the diameter of the through hole 61 is, for example, about 40 to 60 mm.

即ち、まず、図３（ａ）に示すように、橋軸方向Ｘに沿って隣り合う一方の壁高欄１の端面２の溝３の開口３５と他方の壁高欄１の端面２の溝３の開口３５とを向かい合せ、かつ、一方の壁高欄１の端面２と他方の壁高欄１の端面２とが所定の目地間隔５だけ隔てて離間した状態となるように、各壁高欄１，１が設置される。
そして、孔空き鋼板６が、一方の壁高欄１の端面２に形成された溝３内及び他方の壁高欄１の端面２に形成された溝３内に跨ってかつ上下方向Ｚに延長するように設置されることによって、各溝３，３と対向する位置において複数の貫通孔６１，６１…が上下方向Ｚに沿って所定間隔を隔てて配置されるようにする。そして、当該溝３，３内に配置された孔空き鋼板６の複数の貫通孔６１，６１…内に充填されるように、当該溝３，３内、及び、目地間隔５内に充填材７を充填する。 That is, first, as shown in FIG. 3A, the opening 35 of the groove 3 on the end surface 2 of one wall height column 1 and the groove 3 on the end surface 2 of the other wall height column 1 which are adjacent along the bridge axis direction X. Each of the wall height columns 1, 1 faces the opening 35 so that the end surface 2 of one wall height column 1 and the end surface 2 of the other wall height column 1 are separated by a predetermined joint interval 5. Is installed.
The perforated steel sheet 6 extends in the vertical direction Z across the groove 3 formed in the end surface 2 of one wall height column 1 and the groove 3 formed in the end surface 2 of the other wall height column 1. Are arranged at predetermined intervals along the vertical direction Z at positions facing the grooves 3 and 3. And the filler 7 in the said groove | channels 3 and 3 and the joint space | interval 5 are filled so that it may fill in the some through-holes 61, 61 ... of the perforated steel plate 6 arrange | positioned in the said groove | channels 3 and 3. FIG. Fill.

即ち、各溝３，３内に設置された孔空き鋼板６は、各溝３，３内に橋軸方向Ｘに沿って跨り、かつ、上下方向Ｚに延長する平板材の板面を貫通する複数の貫通孔６１，６１…を備えた孔空き平板材として機能する。言い換えれば、板面に摩擦抵抗部として機能する複数の貫通孔６１，６１…を備えた板材としての孔空き鋼板６を使用するようにした。
尚、孔空き鋼板６は、橋軸方向Ｘに隣り合うように設置された一方の壁高欄１の溝３及び他方の壁高欄１の溝３の上方から当該各溝３，３内に挿入されて設置される。
このように、孔空き平板材としての孔空き鋼板６が各溝３，３内に挿入されて設置された後に、図３（ｃ）に示すように、溝３，３内、及び、目地間隔５、複数の貫通孔内にモルタルやコンクリート等の充填材７を充填して、橋軸方向Ｘに沿って隣り合う壁高欄１，１同士を一体化させる。 That is, the perforated steel plate 6 installed in each groove 3, 3 passes through the plate surface of the flat plate material that extends along the bridge axis direction X and extends in the vertical direction Z in each groove 3, 3. It functions as a perforated flat plate material provided with a plurality of through holes 61, 61. In other words, the perforated steel plate 6 as a plate material provided with a plurality of through holes 61, 61... Functioning as friction resistance portions on the plate surface is used.
The perforated steel sheet 6 is inserted into the respective grooves 3 and 3 from above the groove 3 of one wall height column 1 and the groove 3 of the other wall height column 1 installed so as to be adjacent to each other in the bridge axis direction X. Installed.
In this way, after the perforated steel plate 6 as a perforated flat plate material is inserted and installed in each of the grooves 3 and 3, as shown in FIG. 5. Fill the plurality of through holes with a filler 7 such as mortar or concrete, and integrate the adjacent wall height columns 1 and 1 along the bridge axis direction X.

尚、必要に応じて本発明では、各溝３，３内及び目地間隔５内にモルタルやコンクリート等の充填材７が充填された部分を「目地」、各溝３，３内及び目地間隔５内に充填された充填材を「目地材」と呼んで説明する。   If necessary, in the present invention, the portions filled with the filler 7 such as mortar or concrete in the grooves 3 and 3 and the joint interval 5 are referred to as “joints”, and the grooves 3 and 3 and the joint intervals 5 The filler filled in the inside will be referred to as “joint material” for explanation.

実施形態１に係る壁高欄同士の接合構造では、壁高欄１に加わる橋軸方向Ｘの引抜力及び橋軸直角方向Ｙの衝撃力に対して十分に抵抗できる構造となる。
当該構造において、図４に示すように、壁高欄１，１に衝突荷重のような力が作用した場合、孔空き鋼板６には引張力が作用するが、貫通孔６１内に充填された目地材（充填材７）のせん断抵抗Ｓによって橋軸方向Ｘの引抜力Ｒに抵抗する。また、孔空き鋼板６の貫通孔６１内の目地材より伝達される応力Ｐに対しては、端面２に近付くに従って互いに近づくよう傾斜する傾斜面に形成された溝３の左右の溝内壁面３３，３３によって目地材に対する拘束力が大きくなり、孔空き鋼板６の引抜防止効果が大きくなる。
即ち、壁高欄１，１に対して衝突荷重Ｑ等の力が加わることによる壁高欄１，１のズレの際に生じる引張力に対して、孔空き鋼板６の板面に形成された複数の貫通孔６１，６１…が摩擦抵抗部として機能することによって孔空き鋼板６の引抜せん断抵抗が大きくなり、壁高欄１に力が作用した場合に孔空き鋼板６の引抜せん断抵抗によって抵抗する構造となるとともに、溝３の左右の溝内壁面３３，３３による拘束力によって孔空き鋼板６の引抜防止効果をさらに向上させることが可能な構造となる。 In the joint structure between the wall rails according to the first embodiment, the structure can sufficiently resist the pulling force in the bridge axis direction X and the impact force in the direction perpendicular to the bridge axis Y applied to the wall rail 1.
In this structure, as shown in FIG. 4, when a force such as a collision load acts on the wall height columns 1, 1, a tensile force acts on the perforated steel sheet 6, but the joint filled in the through hole 61. The pulling force R in the bridge axis direction X is resisted by the shear resistance S of the material (filler 7). Further, for the stress P transmitted from the joint material in the through hole 61 of the perforated steel plate 6, the left and right groove inner wall surfaces 33 of the grooves 3 formed on the inclined surfaces that are inclined so as to approach each other as they approach the end surface 2. , 33 increases the binding force on the joint material and increases the effect of preventing the perforated steel sheet 6 from being pulled out.
That is, with respect to the tensile force generated when the wall height column 1 or 1 is displaced due to the force such as the collision load Q applied to the wall height column 1 or 1, a plurality of formed on the plate surface of the perforated steel plate 6. The through-holes 61, 61... Function as frictional resistance portions, so that the pulling shear resistance of the perforated steel sheet 6 increases, and when force is applied to the wall rail 1, the structure resists by the pulling shear resistance of the perforated steel sheet 6. In addition, the pulling prevention effect of the perforated steel sheet 6 can be further improved by the restraining force by the left and right groove inner wall surfaces 33, 33 of the groove 3.

また、実施形態１に係る壁高欄同士の接合構造では、孔空き鋼板６が壁高欄１のコンクリート内に埋め込まれていないため、壁高欄１を取替える際には、目地（接合部）を孔空き鋼板６とともに切断すればよく、壁高欄１の取替え作業の容易化及び低コスト化が図れるようになる。
即ち、残した方の壁高欄１の溝３内に残った孔空き鋼板６の半分及び充填材７を溝３から除去した後、この溝３と新しい壁高欄１の溝３とが向かい合うように新しい壁高欄１を配置し、残した方の壁高欄１の溝３と新しい壁高欄１の溝３とに跨るように孔空き鋼板６を溝３，３内に挿入した後、溝３，３内、及び、目地間隔５内にモルタルやコンクリート等の充填材７を充填して、残した方の壁高欄１と新しい壁高欄１とを一体化させればよいので、壁高欄１の取替え作業の容易化及び低コスト化が図れるようになる。 Moreover, in the joining structure of the wall rails according to the first embodiment, since the perforated steel plate 6 is not embedded in the concrete of the wall rail 1, when the wall rail 1 is replaced, the joint (joint portion) is perforated. What is necessary is just to cut with the steel plate 6, and the replacement work of the wall column 1 can be facilitated and the cost can be reduced.
That is, after removing the half of the perforated steel sheet 6 and the filler 7 remaining in the groove 3 of the remaining wall height column 1 from the groove 3, the groove 3 and the groove 3 of the new wall height column 1 face each other. After placing the new wall height column 1 and inserting the perforated steel sheet 6 into the grooves 3 and 3 so as to straddle the groove 3 of the remaining wall height column 1 and the groove 3 of the new wall height column 1, the grooves 3 and 3 It is only necessary to fill the inner wall space 5 with the filler 7 such as mortar or concrete, and to integrate the remaining wall height column 1 and the new wall height column 1 so that the wall height column 1 can be replaced. Can be facilitated and the cost can be reduced.

従って、実施形態１に係る壁高欄同士の接合構造によれば、壁高欄１に加わる橋軸方向Ｘの引抜力及び橋軸直角方向Ｙの衝撃力に対して十分に抵抗できる構造となるとともに、壁高欄１の取替え作業の容易化及び低コスト化が図れるようになる。   Therefore, according to the joint structure between the wall rails according to the first embodiment, it becomes a structure that can sufficiently resist the pulling force in the bridge axis direction X and the impact force in the direction perpendicular to the bridge axis Y applied to the wall rail 1. The replacement work of the wall rail 1 can be facilitated and the cost can be reduced.

また、実施形態１に係る壁高欄同士の接合構造によれば、孔空き鋼板６を各溝３，３内に挿入する構成であるので、床版同士の施工誤差が生じても孔空き鋼板６を各溝３，３内に自由に挿入できるため、施工が容易となる。   Moreover, according to the joining structure of the wall rails according to the first embodiment, since the perforated steel plate 6 is inserted into the grooves 3 and 3, even if a construction error occurs between the floor slabs, the perforated steel plate 6 is provided. Can be freely inserted into each of the grooves 3 and 3, so that the construction becomes easy.
