Description

本発明は、傾斜や切り立った崖上等の段差のある地形や山間部、内海沿岸、湖水際等にあって外側に張り出した歩道構築に用いられる分割、組立形張り出し歩道構造及びその構築方法並びに張り出し歩道ブロックに関する。   The present invention relates to a terrain having a step such as an inclined or steep cliff, a mountainous area, an inland sea coast, a lake, and the like, used for the construction of a sidewalk projecting outward, an assembly-type projecting sidewalk structure, its construction method, and Concerning overhanging sidewalk blocks.

例えば、山の中腹や、谷側、崖等の段差上に設けられた車道では、道の幅も狭く歩行者は常に危険を伴う。従って、車道と分離した歩道の建設が望ましいが、上記のような地形では、スペースが狭いことが多いので、元々狭い車道をさらに車道と歩道に区切ることが困難であり、そのままでは広い歩道を確保することが困難であった。そこで、歩道を建設する際には、車道の縁側に沿って崖から外側に張り出した歩道の建設の必要性が生じる。
従来の張り出し歩道の構造としては、例えば、特許文献１に提案されており、特許文献１の張り出し歩道は、同文献１添付の図１に示すように、谷側法面に構築される擁壁部材と、歩道板と、錘体と、を有しており、歩道板は、擁壁部材と、錘体とにより両持ち支持されて、外側に張り出して構成されている。
特開平７−３１７００５号 For example, on a roadway provided on a mountainside, a valley side, a cliff, etc., the road is narrow and pedestrians are always dangerous. Therefore, it is desirable to construct a sidewalk separate from the roadway. However, in the above terrain, the space is often narrow, so it is difficult to separate the narrow roadway into a roadway and a sidewalk. It was difficult to do. Therefore, when constructing a sidewalk, it is necessary to construct a sidewalk that protrudes outward from the cliff along the edge of the roadway.
As a structure of a conventional overhanging sidewalk, for example, Patent Document 1 has proposed, and the overhanging sidewalk of Patent Document 1 is a retaining wall constructed on a valley side slope as shown in FIG. It has a member, a sidewalk board, and a weight body, and the sidewalk board is both supported by the retaining wall member and the weight body, and is configured to project outward.

It consists of a method for constructing a divided and assembled overhanging sidewalk characterized by supporting the part in a cantilevered manner.

その際、歩道部に略Ｌ字状に脚を連接させ、土台部の張り出し端側に縦壁を配置し、脚を土台部側に配置し、脚と歩道板との隅部付近を縦壁に載せ掛け状に支持させた状態で歩道部の勾配調整を含む位置調整工程と、固化用コンクリート充填工程と、を行うようにするとよい。   At that time, the legs are connected to the sidewalk part in an approximately L shape, a vertical wall is arranged on the protruding end side of the foundation part, the legs are arranged on the foundation part side, and the vertical wall is located near the corner between the leg and the sidewalk board. It is good to perform the position adjustment process including the slope adjustment of a sidewalk part, and the concrete filling process for solidification in the state where it was supported in a hanging shape.

The center of gravity is on the side of the base part with a part of the base part engaged and the sidewalk part arranged horizontally, and a part of the upper board placed on the base part is filled and solidified with cast-in-place concrete Since it is composed of an assembly-type overhanging sidewalk structure that is integrally fixed and the base part and the upper board are integrated, each base and base part can be easily manufactured and moved separately. In addition, it is easy to handle due to its compact size and light weight, and the risk of work is reduced, and the construction period can be shortened and the work cost can be reduced. Furthermore, installation adjustment including fine gradient and height adjustment is possible.

また、上盤は脚と歩道板とからなり、土台部は脚を受け入れる空隙部分を備えた枠体構造から構成することにより、脚と歩道板との一体構造体の脚部分を土台部の空隙にクレーン吊支により配置させるだけで歩道板の片持ち支持による張り出し歩道構造の大まかな設定工事を終了でき、作業分割とともに次の微調整工程へ円滑に移行し得る。   In addition, the upper board consists of legs and sidewalk boards, and the base part is composed of a frame structure with a gap part that accepts the legs, so that the leg part of the integrated structure of the legs and sidewalk board can be The rough setting work of the overhanging sidewalk structure by cantilever support of the sidewalk board can be completed simply by arranging it with the crane suspension support, and the process can be smoothly shifted to the next fine adjustment process together with the work division.

While in a free state, the footboard is placed horizontally so that it can be supported horizontally, and a portion of the footboard placed on the base is fixed to the base and the upper board by filling and solidifying the cast-in-place concrete. By constructing with a method of constructing a divided and assembled overhanging sidewalk characterized by supporting the part in a cantilevered manner, the risk of work is reduced through weight reduction of each part, shortening the work period and working cost Can be realized, and installation adjustment including fine gradient and height adjustment can be greatly simplified.

また、その際に、歩道部に略Ｌ字状に脚を連接させ、土台部の張り出し端側に縦壁を配置し、脚を土台部側に配置し、脚と歩道板との隅部付近を縦壁に載せ掛け状に支持させた状態で歩道部の勾配調整を含む位置調整工程と、固化用コンクリート充填工程と、を行う構成とすることにより、勾配調整や高さ調整を含むブロックの位置調整を簡単な作業で、短期に終了させることが可能である。   At that time, the legs are connected to the sidewalk part in an approximately L shape, a vertical wall is placed on the overhanging end side of the base part, the legs are placed on the base part side, near the corner between the leg and the sidewalk board Of the block including the slope adjustment and the height adjustment by performing the position adjustment process including the slope adjustment of the sidewalk part and the solidifying concrete filling process in a state of being supported on the vertical wall.

詳細には、上盤１４は、脚２８と歩道板３０とを含む。脚２８は、土台部１２に係合して歩道部１２としての歩道板３０を片持ち状に支持させるための上盤１４の一部であり、該脚２８と歩道板３０とはコンクリートの一体成型により形成されている。この実施例において、歩道板３０と脚２８とは側面視Ｌ字状に曲げて接合されている。歩道板３０は施工時には水平状に配置され、脚は図３、６に示すようにこの水平状に配置された歩道板３０に対してＬ字状に下方に連接されている。そして、歩道板３０を水平状に配置した状態で脚２８を土台部の枠体構造の内部の空隙Ｇ内に挿入し、この状態でこの空隙Ｇ内にコンクリートが充填されて固化後、一体固定される。より詳しくは、本実施例では、脚２８は図３に示すように、離隔して２個平行に下方に垂設されている。すなわち、二股状に分割して下方に突設されている。そして、張り出し歩道の構築に際しては、図１、図６に示すように、脚２８の二股の中間間隙部分を土台部１２の連接壁２２に跨って縦に配置させる。   Specifically, the upper board 14 includes a leg 28 and a sidewalk board 30. The leg 28 is a part of the upper board 14 that is engaged with the base portion 12 to support the sidewalk plate 30 as the sidewalk portion 12 in a cantilevered manner, and the leg 28 and the sidewalk plate 30 are made of a single piece of concrete. It is formed by molding. In this embodiment, the sidewalk board 30 and the leg 28 are bent and joined in an L shape in a side view. The sidewalk board 30 is horizontally arranged at the time of construction, and the legs are connected downward in an L shape with respect to the horizontally arranged sidewalk board 30 as shown in FIGS. Then, the leg 28 is inserted into the gap G inside the frame structure of the base portion with the sidewalk board 30 arranged horizontally, and in this state, the gap G is filled with concrete and solidified, and then fixed integrally. Is done. More specifically, in this embodiment, as shown in FIG. 3, two legs 28 are spaced apart and suspended downward in parallel. That is, it is divided into two forks and protrudes downward. When constructing the overhanging sidewalk, the bifurcated intermediate gap portion of the leg 28 is vertically arranged across the connecting wall 22 of the base portion 12 as shown in FIGS. 1 and 6.

歩道部１６は上面が平坦な例えば人の歩行用の歩道面とされる矩形厚板状のコンクリート成型体であり、実施形態において、張り出し方向に長い長矩形形状で構成されている。この歩道板の幅方向両端側はその長辺全長にわたって異なる隅部を切欠いた相欠き状の切欠部Ｔが形成され空間的に嵌合し得るように形成されている。そして、片側の切欠部Ｔにより形成される部分は、上側隅部が切り欠かれて下部から水平方向に突設する突設受部３２が設けられ、これによって、併設する他の張り出し歩道ブロック１０Ｂの上側突設部３４と相欠き継手状に接続される。上盤１４全体は例えば３トン程度、土台部が２トン程度とし、複数の張り出し歩道ブロック１０Ａ，１０Ｂ，１０Ｃ．．．を併設する際に、具体的な施工現場に対応して道路の曲がり部分などがあるが、その際の隣接歩道ブロック間で具体的に生じる隙間へ充填される目地コンクリートの保持がこの突合せ部分の突設受部３２により可能となり、わざわざ型枠組み立て作業等を不要とするばかりか、歩道板本体に一体突設された突設受部３２により振動や不等沈下等の際にもコンクリートが落下することなく、安全性を保持しうる。さらに、図５にも示すように、歩道板３０の下部には、脚２８の高さ中途から斜めにせり上がって歩道板の張り出し端側に向かうにしたがって薄肉となる細長い三角形状の下部補強壁３６が平行に２個設置されている。これらの下部補強壁３６は、脚２８及び歩道板３０とともにコンクリート一体成型により形成される。   The sidewalk 16 is a rectangular thick plate-shaped concrete molded body having a flat upper surface, for example, a sidewalk surface for human walking. In the embodiment, the sidewalk 16 has a long rectangular shape that is long in the protruding direction. Both side ends in the width direction of the sidewalk board are formed so that phase cutout portions T having different corners cut out over the entire length of the long side are formed and can be spatially fitted. And the part formed by the notch part T of one side is provided with the protrusion receiving part 32 which the upper corner part is notched and protrudes in the horizontal direction from the lower part. Are connected to the upper projecting portion 34 in the form of a phased joint. The entire upper board 14 is, for example, about 3 tons and the base portion is about 2 tons, and a plurality of overhanging sidewalk blocks 10A, 10B, 10C. . . There is a curved part of the road corresponding to the concrete construction site, but the joint concrete that is filled in the gap that specifically occurs between adjacent sidewalk blocks at that time The projecting receiving part 32 makes it possible to eliminate the need for the work of assembling the formwork, and also the concrete is dropped by the projecting receiving part 32 integrally projecting on the sidewalk board body in the case of vibration or uneven subsidence. Safety can be maintained without doing this. Further, as shown in FIG. 5, an elongated triangular lower reinforcing wall that is slanted from the middle of the height of the leg 28 toward the projecting end side of the sidewalk board is formed at the lower part of the sidewalk board 30. Two 36 are installed in parallel. These lower reinforcing walls 36 are formed by concrete integral molding together with the legs 28 and the sidewalk board 30.

前述したように、歩道板３０と脚２８とは側面視Ｌ字状に曲げて接合されている。そして、施工時には歩道板３０を水平状に配置し土台部１２にその一部を係合させて歩道部を片持ち状に支持させる。すなわち、本実施例において、Ｌ字状に連結された歩道板３０と脚２８との隅部１０１を土台部１２の外壁２０上に乗せ掛けて配置させる。このとき、上盤の重心は土台部側にあり、自由状態において歩道板を水平状に張り出し突設させた状態であっても谷側等に転倒することはない。この状態でコンクリートが充填される。   As described above, the sidewalk board 30 and the leg 28 are bent and joined in an L shape in a side view. And at the time of construction, the sidewalk board 30 is arranged horizontally, and a part of the sidewalk board 30 is engaged with the base part 12 to support the sidewalk part in a cantilevered manner. That is, in this embodiment, the corner portion 101 of the sidewalk board 30 and the leg 28 connected in an L shape is placed on the outer wall 20 of the base portion 12 and arranged. At this time, the center of gravity of the upper board is on the base part side, and even in a state where the sidewalk board is projected in a horizontal state in a free state, it does not fall down to the valley side or the like. In this state, concrete is filled.

さらに、本実施例において、土台部に支持される歩道板の位置調整機構３８が設けられている。位置調整機構３８は、併設して実用し得る張り出し歩道の構築に際してその歩道部の勾配調整、高さ調整を含む歩道部の位置を調整する機構であり、この実施例において、位置調整機構３８は勾配調整機構２６と、高さ調整機構４２と、を含む。勾配調整機構２６は、特に水平状態の歩道部（歩道面）から例えば図示しない車道側に３パーセントの下がり勾配で実施することを義務付けられる場合等があり、このような場合に対応しうる。実施例では、勾配調整機構２６は、外壁２０の内側に配置された脚２８とその外壁２０との離隔間隙を長短調整する脚移動機構から構成されている。詳細には、この実施例では、
脚２８の下部に穿孔された孔を貫通する調整ボルト４４と、外壁２０内に埋め込まれて外壁の内面側からねじ込み可能に設けられたインサートナット４６と、を含み、調整ボルト４４のインサートナット４６内への螺進退移動により脚２８と外壁２０との間隙を調整することにより歩道板３０の例えば外壁上端部を支点とする左右の揺動による勾配調整を行う。 Furthermore, in this embodiment, a position adjusting mechanism 38 for the sidewalk board supported by the base portion is provided. The position adjustment mechanism 38 is a mechanism that adjusts the position of the sidewalk including the slope adjustment and height adjustment of the sidewalk when constructing an overhanging sidewalk that can be practically used together. In this embodiment, the position adjustment mechanism 38 is A gradient adjusting mechanism 26 and a height adjusting mechanism 42 are included. The gradient adjusting mechanism 26 may be obliged to implement a 3% downward gradient from the horizontal sidewalk (sidewalk surface), for example, on the side of the roadway (not shown), and can cope with such a case. In the embodiment, the gradient adjusting mechanism 26 includes a leg moving mechanism that adjusts the distance between the leg 28 disposed inside the outer wall 20 and the distance between the leg 28 and the outer wall 20. Specifically, in this example,
An adjustment bolt 44 penetrating a hole drilled in the lower portion of the leg 28, and an insert nut 46 embedded in the outer wall 20 and provided so as to be screwable from the inner surface side of the outer wall. By adjusting the gap between the leg 28 and the outer wall 20 by screwing back and forth inward, the gradient adjustment is performed by swinging left and right with the upper end of the outer wall of the sidewalk plate 30 as a fulcrum, for example.

高さ調整機構４２は、歩道板３０の全体高さ調整を行う高さ調整手段であり、この実施形態では、歩道板３０と脚２８とのＬ字隅部での支持位置を上下に調整することにより行う。本実施例において、高さ調整機構４２は図４に示すように上盤１４が載せ掛けられる外壁２０の上端位置を調整する手段により構成されており、詳しくは、外壁２０の上端寄り位置であって、外壁２０の内部に埋め込まれたインサートナット４８と、該インサートナット４８に上から下向きにねじ込まれる高さ調整ボルト５０と、を含み、高さ調整ボルト５０により歩道板の下面の当たり高さを調整し、設定高さが得られたときにモルタルをボルトとの隙間に充填して固化し支持させる。   The height adjustment mechanism 42 is a height adjustment unit that adjusts the overall height of the sidewalk board 30. In this embodiment, the support positions at the L-shaped corners of the sidewalk board 30 and the legs 28 are adjusted up and down. By doing. In this embodiment, the height adjustment mechanism 42 is configured by means for adjusting the upper end position of the outer wall 20 on which the upper board 14 is placed as shown in FIG. And an insert nut 48 embedded in the outer wall 20 and a height adjusting bolt 50 screwed downward into the insert nut 48 from above, and the contact height of the lower surface of the sidewalk plate by the height adjusting bolt 50 When the set height is obtained, the mortar is filled in the gap between the bolts and solidified and supported.

次に、本実施例の作用について説明すると、二次コンクリート製品としての土台部１２と歩道部１６とを施工現場に運搬するが、このように土台部１２と歩道部とが分割されているので、製造、管理、運搬上作業性が良く、また、施工時に比較的に小型のブロックの吊支用重機を用いて作業できるので、施工コストの上でも低廉化に資する。張り出し歩道ブロック１０Ａ，１０Ｂ、１０Ｃ．．．を設置線に沿って配置しながら施工するに際し、まず、Ｈ字の連接壁２２が地盤３００側から張り出し方向Ｐに向かうように立てて土台部１２を設置し、次に上盤１４を例えばクレーン吊支しながら図６のように土台部１２の外壁２０の上面に上盤１４のＬ字隅部を乗せ掛けるようにして配置させる。このとき、上盤１４は歩道部１６を水平状に配置させた状態で重心が土台部側にあるので、自由状態でも歩道部側から谷側に転倒しないようになっている。この状態で、調整ボルト４４や高さ調整ボルト５０を操作しながらそれぞれ歩道板の勾配調整あるいは高さ調整を行う。調整完了後、連結鉄筋５２を複数の併設されたブロック１０Ａ、１０Ｂ．．．の土台部の鉄筋挿入孔２４を串刺し状に貫通して配置し、その後、土台部の上盤が係合する空隙部分Ｇに現場打ちコンクリートを充填し固化して一体化し、これによって、歩道部を片持ち状に支持させた張り出し歩道構造を得る。   Next, the operation of the present embodiment will be described. The foundation part 12 and the sidewalk part 16 as secondary concrete products are transported to the construction site, but the foundation part 12 and the sidewalk part are thus divided. In addition, workability in manufacturing, management and transportation is good, and it is possible to work using a relatively small block suspension heavy machine during construction, which contributes to reduction in construction cost. Overhang sidewalk blocks 10A, 10B, 10C. . . Is installed along the installation line, first, the base portion 12 is set up with the H-shaped connecting wall 22 extending from the ground 300 side in the projecting direction P, and then the upper plate 14 is installed, for example, a crane As shown in FIG. 6, the L-shaped corner of the upper panel 14 is placed on the upper surface of the outer wall 20 of the base 12 while being suspended. At this time, since the center of gravity of the upper board 14 is on the base part side with the sidewalk part 16 arranged horizontally, it does not fall from the side of the sidewalk part to the valley side even in a free state. In this state, the slope adjustment or height adjustment of the sidewalk board is performed while operating the adjustment bolt 44 and the height adjustment bolt 50, respectively. After the adjustment is completed, the connecting rebar 52 is provided with a plurality of blocks 10A, 10B. . . The reinforcing bar insertion hole 24 in the base part of the base part is disposed so as to be skewered, and then the cast-in-place concrete is filled and solidified in the gap part G with which the upper part of the base part engages, thereby integrating the sidewalk part. A canopy sidewalk structure that supports the cantilever is obtained.

このように、本実施例の分割、組み立て形張り出歩道構造では、支持基礎側の土台部と、一部に土台部との連結部分を形成する態様で構成された歩道板を含む上盤と、に分割し、かつ、土台部にその一部を係合させて歩道部を水平状に配置させた状態で重心が土台部側にあるように上盤を形成しているので、それらの二次コンクリート製品の製造、管理、運搬等が簡易に行える上に、歩道板の細かな高さ調整や勾配調整を簡単に行え、さらに、それらの設定調整を従来に比較して短時間で高精度に行える。   Thus, in the division and assembly-type overhanging sidewalk structure of the present embodiment, the base part on the support base side, and the upper board including the sidewalk board configured in a manner of forming a connection part with the base part in part. The upper board is formed so that the center of gravity is on the base part side in a state where the foot part is horizontally arranged with the base part being partly engaged with the base part. The manufacture, management, and transportation of secondary concrete products can be easily performed, and the height and slope of the sidewalk can be easily adjusted. In addition, these settings can be adjusted more quickly and accurately than before. Can be done.

次に、本発明の第２の実施例について、図７ないし図９に基づいて説明するが、前記した第１実施例と同一部材には同一符号を付しその詳細な説明は省略する。この実施例では、上盤６０は、脚６４を含む脚側基体６２と、脚側基体とは別体で形成され脚側基体に一体組み付け可能な歩道板６６と、を有し、該上盤６０は、土台部１２と別体に形成され土台部にその一部を係合させて歩道部１６を片持ち状に支持され、さらに、上盤６０は、土台部にその一部を係合させて歩道部を水平状に配置させた状態で重心が土台部側にあり、土台部に配置させた上盤の一部分を現場打ちコンクリートの充填固化により一体固定させ、土台部と上盤とを一体化させる。   Next, a second embodiment of the present invention will be described with reference to FIGS. 7 to 9. However, the same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In this embodiment, the upper board 60 includes a leg-side base 62 including legs 64 and a sidewalk plate 66 that is formed separately from the leg-side base and can be assembled to the leg-side base. 60 is formed separately from the base portion 12, and a part thereof is engaged with the base portion to support the sidewalk portion 16 in a cantilevered manner. Further, the upper board 60 is engaged with a portion of the base portion. The center of gravity is on the base part side with the sidewalk part placed horizontally, and a part of the upper board placed on the base part is fixed integrally by filling and solidifying the cast-in-place concrete, and the base part and the upper board are Integrate.

この第２実施例では、土台部１２と略同一構成の平面視Ｈ字形状で構成され、連接壁２２は角柱状に形成されている。この実施例で、脚側基体６２は、下方側に伸びる脚６４と脚から水平方向に突出形成された受台６８と、を含み、土台部１２の空隙部分Ｇに脚６４を配置させた状態で重心を土台部側に残して受台６８を水平片持ち状に支持する。受台６８はその上に厚板状の歩道板６６を載置し固定させるだけで歩道板６６を支持させうる歩道板受台手段であり、この実施形態では２個の脚６４から連接されて水平方向に四角枠形状に形成されている。脚側基体６２はコンクリートの一体成型により構成される。   In this 2nd Example, it is comprised by planar view H shape of the structure substantially the same as the base part 12, and the connection wall 22 is formed in prismatic shape. In this embodiment, the leg-side base 62 includes a leg 64 extending downward and a pedestal 68 formed to project from the leg in the horizontal direction, and the leg 64 is disposed in the gap portion G of the base portion 12. The pedestal 68 is supported in a horizontal cantilever shape with the center of gravity remaining on the base side. The pedestal 68 is a sidewalk board pedestal means that can support the sidewalk board 66 simply by placing and fixing a thick plate-like sidewalk board 66 thereon. In this embodiment, the pedestal board 68 is connected to two legs 64. It is formed in a square frame shape in the horizontal direction. The leg-side base 62 is formed by integral molding of concrete.

歩道板６６は、その上面を平坦面とした歩道部分を構成する部位であり、特に、この実施例では、脚側基体６２と分離して別体として構成される。これによって、脚側基体６２による歩道の支持の機能とは別の付加価値を有する張り出し歩道構造を構築できる。例えば、本実施例において、該歩道板６０は、多孔質のボーラスコンクリートからなり、保水性に優れ、雨天時の雨水の跳ね返り防止とともに道路のカラー化、スリップ防止構造、透水性道路等を実現する複層構造の道路を構築できる。また、歩道板６６は薄肉化し軽量に構成しうる。この第２実施例の張り出し歩道ブロックは、例えば図９のように土台部１２に対して係合して設置され、第１実施例と同様に土台部１２と上盤６０とを一体連結して片持ち支持により張り出し道路を構築する。脚側基体６２と、歩道板６６とは例えば図示しない連結ボルトを介して連結固定される。なお、図中６８は隣接歩道ブロック１０Ａ、１０Ｂ、１０Ｃ．．．の土台部の連接壁の下部位置等に配置される連結用鉄筋である。この第２実施例では、第１実施例のように勾配調整機構や高さ調整機構は設けられておらず、連接壁２２と脚の水平延長壁との間に連結鉄筋６８を挿入した状態でそのまま現場打ちコンクリートを充填するだけとしているが、土台部１２の空隙部分Ｇに脚６４を配置させた状態で重心を土台部側に残して受台６８を水平片持ち状に支持するので、この状態でも従来に比して簡単に勾配調整を含む位置調整が可能である。本実施例でも、さらに、インサートナットやボルト等の間隙調整機構を設けて第１実施例と同様に、勾配調整や高さ調整をさらに円滑に行えるようにしてもよい。   The sidewalk board 66 is a part constituting a sidewalk part having an upper surface as a flat surface. In particular, in this embodiment, the sidewalk board 66 is configured separately from the leg-side base 62. Thus, an overhanging sidewalk structure having an added value different from the function of supporting the sidewalk by the leg-side base 62 can be constructed. For example, in the present embodiment, the sidewalk board 60 is made of porous bolus concrete, has excellent water retention, prevents rain water from rebounding in rainy weather, and realizes a road colorization, a slip prevention structure, a water permeable road, and the like. A multi-layer road can be constructed. Further, the sidewalk board 66 can be made thinner and lighter.

It is the connection reinforcing bar arrange | positioned in the lower part position etc. of the connection wall of the foundation part. In the second embodiment, the gradient adjusting mechanism and the height adjusting mechanism are not provided as in the first embodiment, and the connecting rebar 68 is inserted between the connecting wall 22 and the horizontal extension wall of the leg. Although it is only filled with cast-in-place concrete as it is, the pedestal 68 is supported in a horizontal cantilever shape with the leg 64 placed in the gap portion G of the base portion 12 while leaving the center of gravity on the base portion side. Even in the state, the position adjustment including the gradient adjustment can be easily performed as compared with the conventional case. Also in this embodiment, a gap adjusting mechanism such as an insert nut or a bolt may be provided so that the gradient adjustment and the height adjustment can be performed more smoothly as in the first embodiment.

また、本発明の分割、組立形張り出し歩道の構築方法としては、地盤に設置される土台部と、土台部と別体に形成され一端側に歩道部を有する上盤と、を用意し、土台部に上盤の一部を係合させつつ自由状態において上盤自体で歩道部を水平状に支持可能に配置し、
土台部に配置させた上盤の一部分を現場打ちコンクリートの充填固化により土台部と上盤とを一体固定させて歩道部を片持ち状に支持させるものである。さらに、歩道部に略Ｌ字状に脚を連接させ、土台部の張り出し端側に縦壁を配置し、脚を土台部側に配置し、脚と歩道板との隅部付近を縦壁に載せ掛け状に支持させた状態で歩道部の勾配調整を含む位置調整工程と、固化用コンクリート充填工程と、を行うものである。 In addition, as a method for constructing a divided and assembled overhanging sidewalk according to the present invention, a base part installed on the ground and an upper board formed separately from the base part and having a sidewalk part on one end side are prepared. In the free state while engaging a part of the upper board in the part, the side board part is arranged so that it can be supported horizontally in the upper board itself,
A part of the upper board placed on the base part is fixed to the base part and the upper board integrally by filling and solidifying the cast-in-place concrete to support the sidewalk part in a cantilevered manner. In addition, the legs are connected to the sidewalk part in an approximately L shape, a vertical wall is placed on the protruding end side of the base part, the legs are placed on the base part side, and the vicinity of the corner between the leg and the sidewalk board is a vertical wall The position adjustment process including the slope adjustment of the sidewalk part and the solidifying concrete filling process are performed in a state of being supported in a hanging shape.
