【発明の詳細な説明】 産業上の利用分野 この発明は、道路の吹溜りや落石を防止するために構築
される道路の防護シエルターの施工方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a road protective sielter that is constructed to prevent a road drift and rockfall.
従来技術およびその問題点 一般に、海辺等の急峻な斜面に設けられた道路には吹溜
りや落石防止用の防護シエルターが構築されている。Conventional technology and its problems In general, roads provided on steep slopes such as the seaside are equipped with protective shelters for preventing drifts and falling rocks.
従来、この種の防護シエルターは、屋根部と柱部とをプ
レキヤストコンクリートより別々に形成し、これを現場
において建付けるとともに屋根部と柱部とをボルト等で
連結することによつて構築されている。Conventionally, this type of protective sielter is constructed by separately forming a roof portion and a pillar portion from precast concrete, and building this on site, and connecting the roof portion and the pillar portion with bolts or the like. ing.
しかし、このような構成ではラーメン構造特有の性質に
より屋根部と柱部との接合部に相当大の応力が発生する
ため充分な補強をする必要があつた。また、屋根部材と
柱部材は大型のプレキヤストコンクリート部材として形

がきわめて面倒であつた。However, in such a structure, a considerable amount of stress is generated in the joint portion between the roof portion and the column portion due to the characteristics peculiar to the rigid frame structure, so that sufficient reinforcement is required. Further, since the roof member and the pillar member are formed as a large precast concrete member, they are heavy and easily bulky, so that handling such as transportation is extremely troublesome.
また、勾配付きの道路に構築する場合、柱部は鉛直に建
付け、屋根部は道路面と平行に設置する必要があること
から柱部と屋根部との接合部は接合に優利な直角になら
ないため柱部と屋根部との接合部に特別に加工を加える
必要があつた。Also, when constructing on a road with slopes, the pillars must be built vertically and the roof must be installed parallel to the road surface.Therefore, the joint between the pillar and the roof should be at a right angle, which is advantageous for joining. Since it does not happen, it is necessary to add special processing to the joint between the pillar and the roof.

By connecting them together and introducing a prestress to the whole, one curved shed member 8 having a continuous roof portion and column portion is formed. The required number of shed members 8 is produced according to the scale (length) of the protective shelter A to be constructed. Further, the shed member 8 can freely correspond to the scale (width and height) of the protective shelter constructed by connecting the roof blocks 1 and 2 as needed.

ンカー部材で、アンカーボルト等からなる。Subsequently, the shed member 8 is bridged over the road so as to cover the road at a right angle thereto, and the mountain side end of the shed member 8 is fixed to the mountain side slope of the road, and the valley side of the shed member 8 is fixed. Secure the ends to the sides of the road. In this case, the chin portion 9 is formed in advance on the slope surface constructed of cast-in-place concrete, and the mountain side end of the shed member 8 is fixed to the chin portion 9 by an anchor bolt (not shown). In addition, a groove-shaped foundation 10 is constructed on the side of the road, the valley-side end of the shed member 8 is inserted into the foundation 10, and the surrounding area is filled with concrete 11, and if necessary, anchor bolts (not shown). ) To fix it to the base part 10. Reference numerals 1 and 2 are anchor members that integrate the base portion 10 with the road, and are anchor bolts and the like.

参照）。A protective scale A of a predetermined scale is constructed by this construction method, and the column blocks 3,3 are formed between the block blocks 3,3 of the left and right columns of the shed member 8,8 so that the column block 3,3 is tapered. A shaped lighting window 15 is formed. The vertically long triangular lighting window 15 is a block for a pillar when the road has a slope.
There is a visual effect that even if 3 and 3 are built with a slight inclination, they appear as if they were built vertically. The shape of the daylighting window 15 is not limited to the vertically long triangular shape, but may be a vertically rectangular shape or the like. If the road is meandering, adjust the width of the groove joint 13 by widening it, or adjust the roof blocks 1 and 2 and the pillar blocks 3
Is formed into an elongated fan shape so that the entire shed member 8 is formed into an elongated fan shape for use (see FIG. 6).

できる。EFFECTS OF THE INVENTION The present invention is constituted as described above, and according to this construction method, a roof member and a pillar block are tightly bound with each other to form a shed member, and the shed member is connected in the width direction thereof. On the other hand, by installing it on the road, it is possible to construct a protective shelter of a certain scale very easily.
まだ、屋根用ブロツクおよび柱用ブロツクは細部品化さ
れているので軽量化が図れ、運搬等取扱いがきわめて容
易である。Still, since the roof block and the pillar block are made into thin parts, the weight can be reduced and handling such as transportation is extremely easy.
また、防護シエルター全体はアーチ形に形成されている
ので、応力は全体に分散され応力集中を避けることがで
きる。その結果、部材断面をほぼ均一にすることがで
き、構造的並びに経済的に優利である。Further, since the entire protective shelter is formed in an arch shape, the stress is dispersed throughout and the stress concentration can be avoided. As a result, the member cross section can be made substantially uniform, which is advantageous structurally and economically.
また、曲面部分の形状（曲率）を変えることなく、平板
部分の屋根用ブロックのみを適宜継ぎ足してシェッド部
材の長さを変えることができるので、道路の幅員が変わ
っても容易に対応できる。Further, since the length of the shed member can be changed by appropriately adding only the roof block of the flat plate portion without changing the shape (curvature) of the curved surface portion, the width of the road can be easily changed.
また、この場合、曲面部分の屋根用ブロック及び柱用ブ
