Description

本発明は軽量盛土構造体に関し、特に樹脂発泡体ブロックである軽量盛土材を保護するための壁面材と支柱との取り付け構造に特徴を有する軽量盛土構造体に関する。   The present invention relates to a lightweight embankment structure, and more particularly, to a lightweight embankment structure characterized by an attachment structure of a wall material and a column for protecting a lightweight embedding material that is a resin foam block.

軟弱地盤や地滑り地などでの盛土工法の一つとして、EPS工法のように、発泡ポリスチレン(EPS)のような発泡樹脂体からなる樹脂発泡体ブロックを軽量盛土材として用いる軽量盛土構造体が知られている。図13に示すように、施工に際し、適宜の支柱1を立設し、支柱1の背面側と支持地盤2との間に樹脂発泡体ブロック3を多段に積み上げて所定高さの軽量盛土層とする。積み上げた樹脂発泡体ブロック3の上面にはコンクリート床版4が配置され、その上に、仕上げ施工として路盤5やアスファルト舗装6がなされて、軽量盛土構造体とされる。軽量盛土としての樹脂発泡体ブロックは直射日光により劣化しやすいので、それを防ぐために、立設した支柱1の前方面側に軽量コンクリート板のような比較的軽量な壁面材7が多段に取り付けられる。図で8はコンクリート床版4に取り付けられるアンカーである。   As one of the embankment methods on soft ground or landslide land, a lightweight embankment structure using a resin foam block made of a foamed resin body such as expanded polystyrene (EPS) as a lightweight embankment material is known, such as the EPS method. It has been. As shown in FIG. 13, in the construction, an appropriate support column 1 is erected, and the resin foam blocks 3 are stacked in multiple stages between the back side of the support column 1 and the supporting ground 2, To do. A concrete floor slab 4 is disposed on the upper surface of the stacked resin foam block 3, and a roadbed 5 and asphalt pavement 6 are formed thereon as a finish construction to form a lightweight embankment structure. Since the resin foam block as a lightweight embankment is easily deteriorated by direct sunlight, a relatively light wall material 7 such as a lightweight concrete board is attached in multiple stages on the front surface side of the upright support column 1 in order to prevent it. . In the figure, 8 is an anchor attached to the concrete floor slab 4.

施工現場で、立設した支柱に壁面材を多段に取り付けていく作業は容易でなく、簡便かつ安定した取り付け構造を得るための提案が多くなされている。特許文献1には、軽量盛土構造体において、立設した支柱の前方面側に取り付け具を用いて多段に壁面材を取り付ける構造が記載されており、そこでは、裏面にスリット溝を有する壁面材を用い、取り付け金具であるネジ棒の膨出した先端を該スリットに嵌合させた状態で、ネジ棒の他端側を支柱のフランジに固定用金物およびナットを用いて固定するようにしている。ネジ棒の膨出した先端を壁面材裏面のスリットに嵌合させることによって壁面材が前方へ移動するのを阻止しており、ナットを締め付けることにより安定した取り付け状態が得られる。   At the construction site, it is not easy to attach the wall material to the upright column in multiple stages, and many proposals have been made to obtain a simple and stable attachment structure. Patent Document 1 describes a structure in which a wall material is attached in multiple stages using a fixture on the front surface side of an upright support in a lightweight embankment structure, in which a wall material having a slit groove on the back surface is described. , And the other end of the screw rod is fixed to the flange of the column with a fixing hardware and nut in a state where the bulging tip of the screw rod which is a mounting bracket is fitted in the slit. . By fitting the bulging tip of the screw rod into the slit on the back surface of the wall surface material, the wall surface material is prevented from moving forward, and by tightening the nut, a stable mounting state can be obtained.

特許文献2には擁壁構築用型枠パネルの固定構造が記載されており、ここでは、裏面にフックを備えた壁面材を用い、該フックに差し込み可能な突出部を有する固定具の該突出部をフックに差し込んだ状態で、一端を固定具に取り付けた棒部材の他端を後方に立設した支柱に溶接などで仮固定するようにしている。所要段数に壁面材を仮固定した後、背面に生コンクリート、エアモルタル、土砂などの充填材が打設される。   Patent Document 2 describes a fixing structure of a retaining wall construction form panel. Here, the protrusion of a fixture having a protrusion that can be inserted into the hook using a wall material provided with a hook on the back surface. With the part inserted into the hook, the other end of the rod member having one end attached to the fixture is temporarily fixed to a support column standing rearward by welding or the like. After temporarily fixing the wall material to the required number of steps, fillers such as ready-mixed concrete, air mortar, and earth and sand are placed on the back.

特許文献3にはコンクリート構造物構築用の型枠とその施工方法が記載されており、ここでは、裏面にフックを備えた成形板を用い、支柱を成形板の裏面とフックとの間に配置した状態として、そこにくさびを打ち込み、摩擦抵抗でもって成形板を支柱に一体に固定するようにしている。

Patent Document 3 describes a formwork for constructing a concrete structure and a construction method thereof. Here, a molding plate having a hook on the back surface is used, and a column is arranged between the back surface of the molding plate and the hook. In this state, a wedge is driven there, and the molded plate is integrally fixed to the column with frictional resistance.

軽量盛土構造体において、立設した支柱に対する壁面材の取り付けは、簡便でありかつ高い安定性を備えることが望まれるが、その観点から、従来の取り付け構造はなお改良すべき点がある。特許文献1に記載の構造は、壁面材の裏面に形成したスリット溝にネジ棒の膨出した先端を嵌合させる作業やネジ棒の他端をナットで支柱に締め付ける作業など、多段階の煩雑な作業を必要とする。特許文献2に記載の構造も同様であり、壁面材のフックに固定具を差し込んだ後、固定具に取り付けた棒部材の他端側を支柱に溶接するという多段階の作業を必要とする。また、壁面材と支柱とは隔離しており、生コンクリートのような充填材を背面側に打設するまで、壁面材を安定に姿勢維持することができない。   In the lightweight embankment structure, it is desired that the wall material is attached to the upright column in a simple manner and has high stability. From this viewpoint, the conventional attachment structure still needs to be improved. The structure described in Patent Document 1 is a multi-step complicated process, such as an operation of fitting the protruding end of the screw rod into a slit groove formed on the back surface of the wall surface material, or an operation of tightening the other end of the screw rod to the support column with a nut. Work is required. The structure described in Patent Document 2 is the same, and requires a multi-step operation of welding the other end of the bar member attached to the fixture to the support after inserting the fixture into the hook of the wall material. Moreover, the wall surface material and the column are separated from each other, and the wall surface material cannot be stably maintained until a filler such as ready-mixed concrete is placed on the back side.

特許文献3の方法はくさびを打ち込む作業のみで、支柱に対する成形板の取り付けを終了することができ、工程数は少ない。しかし、両者の固定は基本的に摩擦抵抗のみであり取り付けの安定性に欠ける。すなわち、コンクリート型枠として用いる場合のように、施工後にコンクリートを打設して、全体が一体化する場合には格別の問題は生じないが、樹脂発泡体ブロックを軽量盛土として用いる軽量盛土構造体にこの固定方法を用いると、打ち込んだくさびは解放空間に置かれた状態となるので、外からの振動等によってくさびが移動し、固定が解除されてしまう恐れがある。   The method of Patent Document 3 can complete the attachment of the molded plate to the support column only by driving the wedge, and the number of processes is small. However, the fixing of both is basically only the frictional resistance, and the mounting stability is lacking. In other words, when using concrete as a concrete formwork and placing the concrete after construction to integrate the whole, there is no particular problem, but a lightweight embankment structure using a resin foam block as a lightweight embankment. When this fixing method is used, the wedge that has been driven is placed in the release space, so that there is a possibility that the wedge moves due to vibrations from the outside and the fixing is released.

本発明は上記のような事情に鑑みてなされたものであり、軽量盛土構造体において、少ない工程で壁面材を支柱に取り付けることができ、かつ高い取り付け安定性も維持することのできる壁面材取り付け構造を備えた軽量盛土構造体を提供することを目的とする。   The present invention has been made in view of the circumstances as described above, and in a lightweight embankment structure, a wall surface material can be attached to a support column with a small number of steps and can maintain high attachment stability. An object of the present invention is to provide a lightweight embankment structure having a structure.

本発明による軽量盛土構造体は、立設した支柱の前方面側に取り付け具を用いて多段に壁面材が取り付けてあり、前記支柱の後方面側には樹脂発泡体ブロックが軽量盛土材として多段に積み上げてあり、軽量盛土材の上面にはコンクリート床版および路盤などの仕上げ構造材が配置されている構成を少なくとも備える軽量盛土構造体であって、前記取り付け具は支柱に当接する第1領域と壁面材の背面に係合する第2領域とを備え、壁面材の背面には取り付け具の前記第2領域に係合する係合部が設けられており、壁面材と支柱との間には、取り付け具の第1領域を支柱に当接させ第2領域を壁面材の係合部に係合させることにより壁面材が前方へ移動するのを阻止するようにした取り付け構造が支柱に沿って多段に設けられていることを特徴とする(請求項1)。   In the lightweight embankment structure according to the present invention, wall materials are attached to the front surface side of the upright columns in multiple stages using a fixture, and a resin foam block is formed as a lightweight embankment material on the rear surface side of the columns. A light-weight embankment structure having at least a structure in which finishing structure materials such as a concrete floor slab and a roadbed are arranged on the upper surface of the light-weight embankment material, wherein the attachment is in contact with the support column. And a second region that engages with the back surface of the wall material, and an engagement portion that engages with the second region of the fixture is provided on the back surface of the wall material, between the wall material and the column. The mounting structure that prevents the wall surface material from moving forward by bringing the first region of the fixture into contact with the column and engaging the second region with the engaging portion of the wall surface material follows the column. Is provided in multiple stages. To (claim 1).

上記の軽量盛土構造体では、壁面材の取り付けに当たって、立設した支柱に壁面材の裏面を当接させておき、取り付け具の第1領域部分を支柱に押し付けた(当接した)姿勢で取り付け具を下降させる(あるいは既に取り付けてある取り付け具に対して壁面材を下降させる)作業のみで、壁面材背面の係合部と取り付け具の第2領域とが係合した状態となり、壁面材は前方へ移動するのが阻止された状態で支柱に取り付けられる。この作業は1ステップであってきわめて簡便である。さらに、壁面材と取り付け具とは互いに係合した状態で支柱に一体化されており、取り付け状態はきわめて安定であって、振動等の外力が加わっても取り付け構造がはずれることはない。   In the above-mentioned lightweight embankment structure, when attaching the wall surface material, the back surface of the wall surface material is brought into contact with the upright support column, and the first region portion of the attachment tool is pressed (contacted) to the support column. Only by the work of lowering the tool (or lowering the wall material with respect to the already-attached fixture), the engaging portion on the back surface of the wall material and the second region of the fixture are engaged. It is attached to the column in a state where it is prevented from moving forward. This operation is one step and very simple. Furthermore, the wall surface material and the fixture are integrated with the column in a state of being engaged with each other, and the attachment state is extremely stable, and the attachment structure does not come off even when an external force such as vibration is applied.

壁面材は、その背面が支柱の前方面に面接触した姿勢で取り付け具により支柱に取り付けられていてもよく(請求項2)、壁面材の背面と支柱の前方面との間に別部材(緩衝材など)を挟持した姿勢で取り付け具により支柱に取り付けられていてもよい。別部材は壁面材の背面に接着剤などにより一体化されていてもよい。   The wall surface material may be attached to the column by a fixture in a posture in which the back surface is in surface contact with the front surface of the column (Claim 2), and another member (between the back surface of the wall material and the front surface of the column ( It may be attached to the support column with a fixture in a posture holding a cushioning material or the like. The separate member may be integrated on the back surface of the wall material with an adhesive or the like.

壁面材の背面に設けられる係合部と、そこに係合する取り付け具の第2領域の形状は、上下方向への相対的な移動により互いに係合した状態となって、壁面材の前方への移動が阻止された取り付け構造を形成するものであれば任意であり、制限はない。例えば、壁面材の係合部は垂直状にL字をなす部材であり、取り付け具の第2領域はL字状部材に入り込む切り欠き部を備えたもの(請求項3)、壁面材の係合部は先端に膨出部を備える棒部材であり、取り付け具の第2領域は棒部材の本体部が入り込む切り欠き部を備えたもの(請求項4)、あるいは、壁面材の係合部は水平方向にU字をなす部材であり、取り付け具の第2領域はU字状部材に挿入される突出部を備えているもの(請求項5)、などを例示することができる。   The shape of the engaging portion provided on the back surface of the wall surface material and the second region of the fixture engaged therewith is in a state of being engaged with each other by relative movement in the vertical direction, to the front of the wall surface material. There is no limitation as long as it forms an attachment structure in which movement of the film is prevented. For example, the engaging portion of the wall material is a member having an L-shape in a vertical shape, and the second region of the fixture is provided with a notch that enters the L-shaped member (Claim 3). The joint portion is a rod member having a bulging portion at the tip, and the second region of the fixture is provided with a notch portion into which the main body portion of the rod member enters (Claim 4), or the engaging portion of the wall surface material Is a member that forms a U-shape in the horizontal direction, and the second region of the fixture includes a protrusion that is inserted into the U-shaped member (Claim 5).

本発明による軽量盛土構造体において、壁面材を支柱に取り付けた後に壁面材が前方に向けて移動することは確実に阻止されるが、取り付け態様によっては、振動等により、壁面材が横方向、すなわち複数本の支柱が立設する方向に位置ずれする恐れがある。本発明による軽量盛土構造体の好ましい態様では、それを回避するために、支柱は前方面の端縁に沿ってフランジを有しており、取り付け具の第1領域は該フランジと係合あるいは側方から当接する部分を有しており、両者が係合あるいは側方から当接した状態となることにより、壁面材の横方向への移動が阻止される構造を備える(請求項6)。この態様では、壁面材の前方に向けての移動と横方向への移動を確実に阻止することができ、壁面材の取り付け態様はさらに安定する。   In the light-weight embankment structure according to the present invention, the wall material is reliably prevented from moving forward after the wall material is attached to the support column. In other words, there is a risk of displacement in the direction in which a plurality of columns are erected. In a preferred embodiment of the lightweight embankment structure according to the present invention, in order to avoid this, the column has a flange along the edge of the front surface, and the first region of the fixture is engaged or sided with the flange. And a structure in which the wall material is prevented from moving in the lateral direction by being engaged or in a contact state from the side (Claim 6). In this aspect, the movement of the wall surface material toward the front and the movement in the lateral direction can be surely prevented, and the attachment mode of the wall surface material is further stabilized.

本発明によれば、少ない工程で壁面材を支柱に取り付けることができ、かつ高い取り付け安定性をも維持することのできる壁面材取り付け構造を備えた軽量盛土構造体が得られる。   ADVANTAGE OF THE INVENTION According to this invention, the light-weight embankment structure provided with the wall surface material attachment structure which can attach a wall surface material to a support | pillar with few processes and can also maintain high attachment stability is obtained.

以下、図面を参照しながら本発明を実施の形態に基づいて説明する。図1〜図7は、本発明による軽量盛土構造体における支柱と壁面材の取り付け構造のいくつかの例を説明する図であり、単にわかりやすさのために、壁面材と支柱とそこで用いられる取り付け具のみを図示している。図8〜図10は、本発明による軽量盛土構造体で用いる壁面材の3つの例を示している。図11、図12は、本発明による軽量盛土構造体における支柱と壁面材の取り付け構造のさらに他の例を説明する図であり、ここでも、壁面材と支柱とそこで用いられる取り付け具のみを図示している。   Hereinafter, the present invention will be described based on embodiments with reference to the drawings. FIGS. 1-7 is a figure explaining some examples of the attachment structure of the support | pillar and wall surface material in the lightweight embankment structure by this invention, and only the wall material, the support | pillar, and the fixture used there for easy understanding. Only shown. 8 to 10 show three examples of wall materials used in the lightweight embankment structure according to the present invention. FIG. 11 and FIG. 12 are diagrams for explaining still another example of the structure for attaching the column and wall material in the lightweight embankment structure according to the present invention. Here, only the wall material, the column and the fixture used there are illustrated. Show.

図1に示す例において、支柱10は、2本のC型鋼11,11をその背面12同士で当接させた姿勢のものであり、各C型鋼11の前方面および後方面の端縁にはフランジ13が立てられている。支柱10は、図13に基づき説明した従来の軽量盛土構造体におけると同様にして支持地盤に立設されており、図1には示されないが、支柱10の後方面側には樹脂発泡体ブロック3が軽量盛土材として多段に積み上げられ、軽量盛土材3の上面にはコンクリート床版4や路盤5、アスファルト舗装6などの仕上げ構造材が配置されている。そして、支柱10の前方面側に、本発明による固有の取り付け手段によって、壁面材7が多段に取り付けられている。なお、図1では支柱10は1本のみが示されるが、実際の施工現場では、所定の間隔で必要本数の支柱10・・が立設されており、以下の実施の形態では、支柱10,10間の間隔と同じ横幅を持つ壁面材7が、支柱10・・間をわたるようにして取り付けられる。   In the example shown in FIG. 1, the support column 10 has a posture in which two C-shaped steels 11, 11 are brought into contact with each other on the back surfaces 12. A flange 13 is raised. The column 10 is erected on the supporting ground in the same manner as in the conventional lightweight embankment structure described with reference to FIG. 13 and is not shown in FIG. 3 are stacked in multiple stages as lightweight embankment materials. On the upper surface of the lightweight embankment material 3, finishing structure materials such as a concrete floor slab 4, a roadbed 5, and an asphalt pavement 6 are arranged. And the wall surface material 7 is attached to the front surface side of the support | pillar 10 in multiple stages by the intrinsic | native attachment means by this invention. In FIG. 1, only one support column 10 is shown. However, in an actual construction site, a necessary number of support columns 10 are erected at a predetermined interval. A wall material 7 having the same width as the interval between 10 is attached so as to cross between the columns 10.

本発明において用いられる壁面材7は、基本的には従来の軽量盛土構造体で用いられる矩形状の壁面材であり、軽量コンクリートなどで造られる。ただし、背面側における長手方向の中央領域と両側辺領域には、適宜の手法により係合具21が設けられている。図1に示す取り付け構造で用いる壁面材7が図8に示される。この壁面材7では、係合具21として、L字型をなす鋼材で造られたL字型係合具21aが用いられる。L字型係合具21aは水平基部22aと立ち上がり部22bを有し、水平基部22aの端部は壁面材7内に埋め込まれている。   The wall material 7 used in the present invention is basically a rectangular wall material used in a conventional lightweight embankment structure and is made of lightweight concrete or the like. However, the engagement tool 21 is provided in the center region and both side regions in the longitudinal direction on the back side by an appropriate method. A wall material 7 used in the mounting structure shown in FIG. 1 is shown in FIG. In this wall member 7, an L-shaped engagement tool 21 a made of an L-shaped steel material is used as the engagement tool 21. The L-shaped engagement tool 21 a has a horizontal base portion 22 a and a rising portion 22 b, and the end portion of the horizontal base portion 22 a is embedded in the wall surface material 7.

壁面材7の長手方向の中央領域には、支柱10の横幅よりもやや広い間隔aをおいて、上辺側に2個、下辺側に2個のL字型係合具21aが取り付けてある。上辺側の2個のL字型係合具21aは、立ち上がり部22bが水平基部22aから上方に向けて延びており、下辺側の2個のL字型係合具21aは、立ち上がり部22bが水平基部22aから下方に向けて延びている。左右両側辺領域には、側辺からa/2の距離だけ内側に入った位置に、上辺側に1個、下辺側に1個のL字型係合具21aが取り付けてあり、中央領域におけると同様、上辺側のL字型係合具21aは、水平基部22aから上方に向けて立ち上がり部22bが延びており、下辺側のL字型係合具21aは、水平基部22aから下方に向けて立ち上がり部22bが延びている。なお、水平基部22aの長さは、使用する取り付け具30の板厚とほぼ同じとされる。   In the central region in the longitudinal direction of the wall surface material 7, two L-shaped engagement tools 21 a are attached on the upper side and two L-shaped engagement tools 21 a on the lower side with an interval a slightly wider than the lateral width of the column 10. The two L-shaped engagement tools 21a on the upper side have a rising portion 22b extending upward from the horizontal base portion 22a, and the two L-shaped engagement tools 21a on the lower side have a rising portion 22b. It extends downward from the horizontal base 22a. In the left and right side regions, one L-shaped engagement tool 21a is attached on the upper side and one side on the lower side at a position a / 2 distance from the side. Similarly, the upper side L-shaped engagement tool 21a has a rising portion 22b extending upward from the horizontal base 22a, and the lower side L-shaped engagement tool 21a is directed downward from the horizontal base 22a. The rising portion 22b extends. Note that the length of the horizontal base portion 22a is substantially the same as the plate thickness of the fixture 30 to be used.

本発明において用いる取り付け具30は、支柱10に係合する第1領域31と、上記した壁面材7の背面に設けた係合具21に係合する第2領域32とを備える。図1に示す取り付け構造で用いる取り付け具30は、鋼板を曲げ加工と切削加工して造られており、前記第1領域31は、支柱10のフランジ13に嵌合するU字状部31aであり、前記第2領域32は、平面部32aとその上下の端縁に形成した垂直方向の切り欠き33とで構成される。   The mounting tool 30 used in the present invention includes a first region 31 that engages with the support column 10 and a second region 32 that engages with the engaging tool 21 provided on the back surface of the wall surface material 7 described above. The mounting tool 30 used in the mounting structure shown in FIG. 1 is made by bending and cutting a steel plate, and the first region 31 is a U-shaped portion 31 a that fits into the flange 13 of the column 10. The second region 32 includes a flat portion 32a and vertical cutouts 33 formed at upper and lower edges thereof.

壁面材7を支柱10に取り付けるには、下段の壁面材7aを、中央領域のL字型係合具21a、21aの間に支柱10が入り込むようにして、その背面を支柱10の前方面に当接する。その左右にも、必要枚数の壁面材7を同様にして配置する。その状態で、作業者は取り付け具30を手に持ち、第1領域31であるU字状部31aを支柱10のフランジ13に嵌合させた姿勢で、取り付け具30を上方から下方に向けて移動させる。それにより、取り付け具30の前記下方の切り欠き33と、壁面材7の背面に取り付けたL字型係合具21aとは次第に係合する状態となり、切り欠き33の上端縁がL字型係合具21aの水平基部22aに衝突した位置で、取り付け具30は停止する。同じ作業を支柱10の他方のフランジ13についても行う。   In order to attach the wall surface material 7 to the support column 10, the lower wall surface material 7 a is placed between the L-shaped engagement tools 21 a, 21 a in the center region, and the back surface is placed on the front surface of the support column 10. Abut. The required number of wall surface materials 7 are also arranged on the left and right in the same manner. In this state, the operator holds the attachment tool 30 in his / her hand and faces the attachment tool 30 downward from above in a posture in which the U-shaped portion 31a which is the first region 31 is fitted to the flange 13 of the support column 10. Move. As a result, the lower notch 33 of the attachment 30 and the L-shaped engagement tool 21a attached to the back surface of the wall surface material 7 are gradually engaged, and the upper end edge of the notch 33 has an L-shaped engagement. The attachment tool 30 stops at the position where it collides with the horizontal base 22a of the tool 21a. The same operation is performed on the other flange 13 of the column 10.

L字型係合具21aが停止した姿勢では、L字型係合具21aの立ち上がり部22bは取り付け具30の平面部32aの背面にほぼ接した状態にあり、壁面材7は、前方への移動が阻止された状態で支柱10に取り付けられる。また、その状態で取り付け具30のU字状部31aを支柱10のフランジ13に嵌合しており、壁面材7の横方向の移動も阻止される。   In the posture in which the L-shaped engagement tool 21a is stopped, the rising portion 22b of the L-shaped engagement tool 21a is substantially in contact with the back surface of the flat surface portion 32a of the attachment tool 30, and the wall surface material 7 is moved forward. It is attached to the column 10 in a state where the movement is blocked. Moreover, the U-shaped part 31a of the fixture 30 is fitted in the flange 13 of the support | pillar 10 in that state, and the horizontal movement of the wall surface material 7 is also prevented.

次ぎに、上段の壁面材7bの取り付けを行う。図1の例では、下段の壁面材7aの列と上段の壁面材7bの列は千鳥状をなすように配列しており、そのために、上段の壁面材7bの右側辺領域の背面を、支柱10の図1で左側に位置するC型鋼11の前方面に当接させた姿勢として、上方から下方に向けてスライドさせる。既に取り付けてある下段の壁面材7aに近付くと、側辺領域の下方に取り付けたL字型係合具21aが、既に取り付けてある取り付け金具30の上方の切り欠き33内に次第に入り込んでいき、下方の壁面材7aに当接した時点で、壁面材7bの移動は停止する。停止した時点で、上方の壁面材7bは、下方の壁面材7aの場合と同様、前方および横方向への移動が規制された姿勢で支柱10に対して取り付けられる。さらに、図で右側に位置することとなる上段の壁面材7bを、その左側縁領域を支柱10の左側に位置するC型鋼11の前方面に当接させた姿勢として、上方から下方に向けてスライドさせることにより、その壁面材7bも、同様にして支柱10に対して取り付けられる。   Next, the upper wall material 7b is attached. In the example of FIG. 1, the row of the lower wall member 7a and the row of the upper wall member 7b are arranged in a zigzag pattern. For this reason, the back surface of the right side region of the upper wall member 7b is attached to the column. 10 is slid from the upper side to the lower side as a posture in contact with the front surface of the C-shaped steel 11 located on the left side in FIG. When approaching the lower wall member 7a already attached, the L-shaped engagement tool 21a attached below the side region gradually enters the notch 33 above the attachment fitting 30 already attached, The movement of the wall surface material 7b stops when it contacts the lower wall surface material 7a. When stopped, the upper wall member 7b is attached to the support column 10 in a posture in which movement in the front and lateral directions is restricted, as in the case of the lower wall member 7a. Furthermore, the upper wall material 7b which is located on the right side in the figure is directed from the upper side to the lower side in a posture in which the left edge region is brought into contact with the front surface of the C-shaped steel 11 located on the left side of the support column 10. By sliding, the wall surface material 7b is also attached to the column 10 in the same manner.

以下、壁面材7bを下端の壁面材として、さらに上段の壁面材7cを、前記した壁面材7aの取り付け態様と同様にして支柱10に取り付ける。この作業を必要段数にわたって反復することにより、壁面材の取り付け作業は終了する。なお、図1で、40は第2の取り付け具を示しており、第2の取り付け具40は、取り付け具30の第2領域32のみで形成されている。第2の取り付け具40は、図示のように、支柱10が位置しない箇所での、上下および左右の壁面材7同士を接合するのに用いられる。   Hereinafter, the wall surface material 7b is used as the wall material at the lower end, and the upper wall material 7c is attached to the support column 10 in the same manner as the above-described manner of attaching the wall surface material 7a. By repeating this operation over the required number of steps, the wall material attaching operation is completed. In FIG. 1, reference numeral 40 denotes a second attachment tool, and the second attachment tool 40 is formed only by the second region 32 of the attachment tool 30. The 2nd attachment tool 40 is used for joining the wall material 7 of the upper and lower sides and right and left in the location where the support | pillar 10 is not located like illustration.

上記のように、本発明による軽量盛土構造体では、支柱10に壁面材7を取り付けるに際し、壁面材7の背面を支柱10の前方面に当接させ、その状態で、取り付け具30を支柱10に沿って移動させる、あるいは、既に取り付けてある取り付け具30に対して、壁面材7を支柱10に沿って移動させることにより、壁面材7の支柱に対する取り付け作業を終えることができるので、取り付け作業はきわめて簡素化する。また、その取り付け状態は、壁面材7側の係合具21と取り付け具30の第2領域32とが互いに係合した状態であり、きわめて安定した取り付けが得られる。   As described above, in the lightweight embankment structure according to the present invention, when the wall surface material 7 is attached to the support column 10, the back surface of the wall surface material 7 is brought into contact with the front surface of the support column 10, and in this state, the attachment tool 30 is attached to the support column 10. If the wall surface material 7 is moved along the support column 10 with respect to the fixture 30 that has already been attached, the mounting operation of the wall surface material 7 on the support column can be completed. Greatly simplifies. Moreover, the attachment state is a state in which the engagement tool 21 on the wall surface material 7 side and the second region 32 of the attachment tool 30 are engaged with each other, and extremely stable attachment is obtained.

図示の例では、壁面材7の背面が支柱10の前方面に直接面接触で当接するようにしたが、壁面材7の背面における支柱10に対向する部分に、適宜の緩衝材を配置した状態で、上記の取り付け作業を行うようにしてもよい。   In the illustrated example, the back surface of the wall surface material 7 is brought into contact with the front surface of the support column 10 by direct surface contact. However, an appropriate cushioning material is disposed on a portion of the back surface of the wall surface material 7 facing the support column 10. Then, you may make it perform said attachment operation | work.

図2は、本発明による軽量盛土構造体における支柱と壁面材の他の取り付け構造を示している。ここでは、取り付け具30aの第1領域31が、U字状部31aとそこから側方に広がる平面部34とで構成される点で、図1に説明したものと相違する。この平面部34は、好ましくは支柱10を構成するC型鋼11の前方面の内法幅とほぼ同じ幅とされる。この形状の取り付け具30aを用いることにより、より安定した取り付け状態が得られる。なお、同じ部材には同じ符号を付し、取り付け手順などの説明は省略する。   FIG. 2 shows another mounting structure of the support and wall material in the lightweight embankment structure according to the present invention. Here, the first region 31 of the fixture 30a is different from that described with reference to FIG. 1 in that the first region 31 includes a U-shaped portion 31a and a planar portion 34 that extends laterally therefrom. The flat portion 34 preferably has a width substantially equal to the internal width of the front surface of the C-shaped steel 11 constituting the support column 10. By using the attachment 30a having this shape, a more stable attachment state can be obtained. In addition, the same code | symbol is attached | subjected to the same member and description of an attachment procedure etc. is abbreviate | omitted.

図3は、本発明による軽量盛土構造体における支柱と壁面材のさらに他の取り付け構造を示している。ここでは、取り付け具30bの第1領域31であるU字状部31a1の内法幅が図1に示したU字状部31aよりも広くされている点で、図1に説明したものと相違する。このように内法幅の広いU字状部31a1を持つ取り付け具30bを使用することにより、施工誤差や係合具21の壁面材7への取り付け誤差に対して容易に対処することが可能となる。なお、ここでも、同じ部材には同じ符号を付し、取り付け手順などの説明は省略する。   FIG. 3 shows still another attachment structure of the support and wall material in the lightweight embankment structure according to the present invention. Here, the inner width of the U-shaped portion 31a1 which is the first region 31 of the fixture 30b is wider than that of the U-shaped portion 31a shown in FIG. To do. By using the attachment tool 30b having the U-shaped portion 31a1 having a wide internal width in this way, it is possible to easily cope with construction errors and attachment errors of the engagement tool 21 to the wall surface material 7. Become. Here, the same reference numerals are assigned to the same members, and the description of the attachment procedure and the like is omitted.

図4は、本発明による軽量盛土構造体における支柱と壁面材のさらに他の取り付け構造を示している。ここでは、取り付ける壁面材7Aの背面に設ける係合具21が、L字型係合具21aではなく、図9に示すように、本体部23aの先端が膨出部23bとされた棒部材21bである壁面材7Aを用いている点で相違する。棒部材21bの本体部23aの長さは、用いる取り付け具30の板厚とほぼ同じとされる。なお、係合具21としての棒部材21bの取り付け位置は、図8に基づき説明した壁面材7と同じである。この壁面材7Aの支柱10への取り付け方は、図8に示した壁面材7を用いる場合と実質的に同じであり、同じ部材には同じ符号を付して、説明は省略する。また、図4では取り付け具として、図2に示した取り付け具30aを示したが、図1に示す取り付け具30,図3に示す取り付け具30bも、特に図示しないが、同様にして用いることができる。   FIG. 4 shows still another structure for attaching the column and wall material in the lightweight embankment structure according to the present invention. Here, the engaging member 21 provided on the back surface of the wall surface material 7A to be attached is not the L-shaped engaging member 21a, but a bar member 21b in which the tip of the main body 23a is a bulging portion 23b as shown in FIG. The difference is that the wall material 7A is used. The length of the main body 23a of the bar member 21b is substantially the same as the plate thickness of the fixture 30 used. In addition, the attachment position of the bar member 21b as the engaging tool 21 is the same as the wall surface material 7 demonstrated based on FIG. The method of attaching the wall surface material 7A to the support column 10 is substantially the same as the case of using the wall surface material 7 shown in FIG. 8, and the same members are denoted by the same reference numerals and description thereof is omitted. 4 shows the attachment tool 30a shown in FIG. 2 as an attachment tool, the attachment tool 30 shown in FIG. 1 and the attachment tool 30b shown in FIG. it can.

図5は、本発明による軽量盛土構造体における支柱と壁面材のさらに他の取り付け構造を示している。ここでは、上記のように、1つの取り付け具30で、上下2枚の壁面材7aと壁面材7bあるいは壁面材7bと壁面材7cを、支柱10に対して同時に取り付けるのではなく、個々の壁面材7Aを独立的に支柱10に取り付けている。そのために、取り付け具30cとして、第2領域32の下端縁にのみ垂直方向の切り欠き33が形成された高さの低いものを用いている。なお、図示される取り付け具30cの基本形状は、図2および図4に示した取り付け具30aと同じであるが、図1あるいは図3に示した取り付け具30、30bと同じ基本形状であってもよい。   FIG. 5 shows still another structure for attaching the column and wall material in the lightweight embankment structure according to the present invention. Here, as described above, the single wall surface material 7a and the wall surface material 7b or the wall surface material 7b and the wall surface material 7c are not attached to the support column 10 at the same time by using one mounting tool 30. The material 7A is attached to the column 10 independently. For this purpose, as the attachment tool 30c, a tool having a low height in which a vertical cutout 33 is formed only at the lower edge of the second region 32 is used. The basic shape of the mounting tool 30c shown in the figure is the same as the mounting tool 30a shown in FIGS. 2 and 4, but is the same basic shape as the mounting tools 30, 30b shown in FIG. 1 or FIG. Also good.

この取り付け具30cを用いる場合には、上記した場合のように、壁面材7Aを下から上に順を追って取り付けていく必要はなく(もちろん、そのようにして取り付けてもよい)、多段に壁面材7Aを支柱10に当接させておき、個々の係合具21bに対して取り付け具30cを順不同にスライドさせながら係合させていくことができる。なお、取り付け具30cを用いて、図8に示したL字型係合具21aを持つ壁面材7を取り付ける場合には、下辺側のL字型係合具21aの向きを反転させることが必要となる。また、支柱10のない箇所では、図1に示した第2の取り付け具40が用いられる。   When using this attachment tool 30c, it is not necessary to attach the wall surface material 7A in order from the bottom to the top as in the case described above (of course, it may be attached in this manner), and the wall surface is multi-staged. The material 7A can be brought into contact with the support column 10, and can be engaged with the individual engaging tools 21b while sliding the mounting tool 30c in random order. When the wall member 7 having the L-shaped engagement tool 21a shown in FIG. 8 is attached using the attachment tool 30c, it is necessary to reverse the direction of the L-shaped engagement tool 21a on the lower side. It becomes. Moreover, the 2nd attachment tool 40 shown in FIG. 1 is used in the location without the support | pillar 10. FIG.

図6と図7は、本発明による軽量盛土構造体における支柱と壁面材のさらに他の取り付け構造を示している。ここでは、図10に示すように、背面に設ける係合具21が水平方向にU字をなす部材21cである壁面材7Bを用いている点で相違している。U字をなす部材21cは、鋼材を湾曲させたものでもよく、鋼ワイヤであってもよい。いずれの場合も、先端側は壁面材7B内に埋設している。係合具21としての水平方向にU字をなす部材21cを取り付ける位置は、図8に基づき説明した壁面材7と同じである。   FIG. 6 and FIG. 7 show still another attachment structure of the column and wall material in the lightweight embankment structure according to the present invention. Here, as shown in FIG. 10, the engagement tool 21 provided on the back surface is different in that a wall surface member 7B which is a member 21c having a U-shape in the horizontal direction is used. The U-shaped member 21c may be a curved steel material or a steel wire. In either case, the tip side is embedded in the wall surface material 7B. The position of attaching the U-shaped member 21c as the engaging tool 21 in the horizontal direction is the same as that of the wall surface material 7 described with reference to FIG.

この形態の壁面材7Bを、支柱10に対して前方に移動しないように取り付けるには、水平方向にU字をなす部材21cの中に遊びのない状態で取り付け具30の一部が挿入される必要がある。図6に示す取り付け構造は、前記した図1に示す取り付け構造に対応するものであるが、ここで用いる取り付け具30dは、その第2領域32が鋼板を壁面材7Bの背面に向けて垂直に折り曲げた立ち上がり片32bとされている。なお、第1領域31の形状は任意であるが、ここでは支柱10のフランジ13に側方から当接する第2の立ち上がり片31bとされている。   In order to attach the wall surface material 7B of this form so as not to move forward with respect to the support column 10, a part of the attachment tool 30 is inserted into the member 21c having a U shape in the horizontal direction without play. There is a need. The attachment structure shown in FIG. 6 corresponds to the attachment structure shown in FIG. 1 described above, but the attachment 30d used here has a second region 32 perpendicular to the back surface of the wall surface material 7B. The rising piece 32b is bent. In addition, although the shape of the 1st area | region 31 is arbitrary, it is set as the 2nd standing piece 31b contact | abutted from the side to the flange 13 of the support | pillar 10 here.

取り付け具30dの第2領域32を形成する立ち上がり片32bにおける、前記U字をなす部材21cの中に挿入される上下の突出部32c,32cの高さを、適宜設定することにより、図1に基づき説明したと同様な手順で、上下の壁面材7Bを同時に支柱10に対して安定的に取り付けることができる。なお、図6で40aは、第2の取り付け具を示しており、第2の取り付け具40aは取り付け具30dの第2領域32のみで形成されている。使い方は図1などに示した第2の取り付け具40と同様である。   By appropriately setting the heights of the upper and lower protrusions 32c and 32c inserted into the U-shaped member 21c in the rising piece 32b that forms the second region 32 of the attachment 30d, FIG. The upper and lower wall surface materials 7B can be stably attached to the support column 10 simultaneously by the same procedure as described above. In FIG. 6, reference numeral 40a denotes a second attachment tool, and the second attachment tool 40a is formed only by the second region 32 of the attachment tool 30d. The usage is the same as that of the second fixture 40 shown in FIG.

図7に示す取り付け構造は、前記した図5に示す取り付け構造と類似しており、個々の壁面材7Bを独立的に支柱10に取り付けている。そのために、取り付け具30eとして、立ち上がり片32bの下端縁にのみ前記U字をなす部材21cの中に挿入される突出部32cを備えたものが用いられる。なお、図示の取り付け具30eは、第1領域として第2の立ち上がり片31bの下端をさらに水平方向に折り曲げた部分31cを有しており、それにより安定した取り付け態様が得られるが、部分31cは省略してもよい。壁面材7Bの取り付け手順は、図5に基づき説明したものと同様である。   The attachment structure shown in FIG. 7 is similar to the attachment structure shown in FIG. 5 described above, and each wall surface material 7B is attached to the column 10 independently. For this purpose, the attachment 30e is provided with a protruding portion 32c inserted into the U-shaped member 21c only at the lower end edge of the rising piece 32b. Note that the illustrated attachment tool 30e has a portion 31c in which the lower end of the second rising piece 31b is further bent in the horizontal direction as a first region, thereby obtaining a stable attachment mode. It may be omitted. The procedure for attaching the wall surface material 7B is the same as that described with reference to FIG.

上記では、支柱10としてフランジ13を持つC型鋼11を用いるようにしたが、フランジのないC型鋼11aを支柱10として用いることもでき、また、H型鋼を用いることもできる。図11はフランジのないC型鋼11aを支柱10として用いる場合を例示しており、ここで使用する取り付け具30fは、全体が平板であり、図で右半分が第1領域31を構成し、左半分が第2領域32を構成する。そして、第2領域32には、垂直方向の切り欠き33が形成されている。図示しないが、第1領域31と第2領域32との間に、C型鋼11aの板厚分の段差が形成されていてもよい。図11では壁面材7の例として図9に示した壁面材7Aを用いており、取り付け構造としては図4に示したものに相当し、その取り付け手順は図4に示すものと同じである。   In the above description, the C-shaped steel 11 having the flange 13 is used as the support column 10. However, the C-shaped steel 11 a without a flange can be used as the support column 10, and H-shaped steel can also be used. FIG. 11 exemplifies a case where C-shaped steel 11a without a flange is used as the column 10, and the attachment tool 30f used here is a flat plate as a whole, and the right half in the figure constitutes the first region 31, and the left Half constitutes the second region 32. A vertical cutout 33 is formed in the second region 32. Although not shown, a step corresponding to the plate thickness of the C-shaped steel 11 a may be formed between the first region 31 and the second region 32. In FIG. 11, the wall surface material 7A shown in FIG. 9 is used as an example of the wall surface material 7, and the attachment structure corresponds to that shown in FIG. 4, and the attachment procedure is the same as that shown in FIG.

また、図11に示す例では、支柱10は1本のC型鋼11aのみで構成されているが、フランジを有しない2本のC型鋼11aで支柱10を構成するようにしてもよい。図11に示す1本のC型鋼11aで支柱10を構成する場合でも、横方向に複数枚の壁面材を連続して取り付けることにより、壁面材の横方向の移動を阻止することができる。   Moreover, in the example shown in FIG. 11, the support | pillar 10 is comprised only with one C-shaped steel 11a, However, You may make it comprise the support | pillar 10 with the two C-shaped steel 11a which does not have a flange. Even when the column 10 is constituted by one C-shaped steel 11 a shown in FIG. 11, the wall material can be prevented from moving in the lateral direction by attaching a plurality of wall materials continuously in the lateral direction.

図12は支柱10としてH型鋼10Hを用いている。この場合も、図11に示したと同様にして、上記した全体が平板である取り付け具30fを用いて壁面材7Aを取り付けることができることは、説明を要しない。   In FIG. 12, H-shaped steel 10H is used as the support 10. Also in this case, it is not necessary to explain that the wall surface member 7A can be attached using the attachment 30f, which is a flat plate as described above, in the same manner as shown in FIG.

図11および図12に示す取り付け構造において、図8に示す形態の壁面材7も同様にして支柱10に取り付けることができる。また、図示しないが、フランジのない支柱を用いる場合であっても、下端側にのみ切り欠き33を有する平板状の取り付け具を用いて、図5あるいは図7に示す構造のように、個々の壁面材を独立的に支柱10に取り付けることもできる。   In the attachment structure shown in FIGS. 11 and 12, the wall surface material 7 having the form shown in FIG. Although not shown in the figure, even when a pillar without a flange is used, each plate-like mounting tool having a notch 33 only on the lower end side is used, as in the structure shown in FIG. 5 or FIG. A wall material can also be attached to the column 10 independently.
