この発明は布製型枠を用いたコンクリ−Ｉ・法枠工等の
保護層の施工法およびこの施工法に用いる布製型枠に関
する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for constructing a protective layer in concrete I, slope construction, etc. using fabric formwork, and to a fabric formwork used in this construction method.
法面等の地表面に袋状の布製型枠を敷設し、その内部に
モルタル、コンクリートあるいは土砂等の水性スラリー
類を注入、充填して保護層を形成する施工法が実用化さ
れている。A construction method has been put into practical use in which a bag-like cloth formwork is laid on the ground surface, such as a slope, and a protective layer is formed by injecting and filling the inside of the formwork with a water-based slurry such as mortar, concrete, or earth and sand.

上がり布製型枠１のタテ、ヨコ方向の寸法が著しく小さ
くなる。For example, in the cloth formwork 1 used in this conventional construction method, as shown in Fig. 5, drawing threads 3 are attached between the front and back fabrics 2, 2 with a predetermined distance between the corners, and concrete is placed between the front and back fabrics 2, 2. When an aqueous slurry 4 such as a slurry is injected, the distance between the front and back fabrics 2, 2, that is, the thickness of the protective layer must be a predetermined thickness. However, due to the injection pressure of the aqueous slurry 4, the surface of the fabric 2 between the drawing threads 3, 3 curves and swells into a spherical shape, and the dimensions of the fabric formwork 1 in the vertical and horizontal directions are significantly reduced.

配が急な場合は、スラリーの重量により布製型枠全体が
法面下方にズリ落ちる危険性があった。For this reason, for example, when constructing a slope by laying fabric formwork on a slope and injecting concrete slurry from above the slope, the fabric formwork should be laid in advance with allowance for shrinkage in the horizontal direction. Regarding the vertical direction of the slope, a method is used in which an allowance is raised above the slope and the allowance is gradually drawn downward as the slurry is filled. However, with this method, if the horizontal direction of the balls (the alignment of the spherical spun parts) is uneven depending on the method of pumping out, or if the slope is steep, the weight of the slurry may cause the entire fabric formwork to be flat on the slope. There was a danger of it slipping downwards.

てあることを特徴とする。This method of constructing a protective layer using cloth formwork involves laying a bag-shaped cloth formwork on the ground surface and injecting an aqueous slurry to form a protective layer. It is characterized in that rod-like bodies are fixed along both the vertical and horizontal directions of the fabric formwork, or in one direction thereof, and the dimensions of the fabric formwork are regulated to the dimensions of the protective layer to be formed in advance. Another aspect of the invention is a bag-like cloth formwork in which an aqueous slurry is injected to form a protective layer, and the cloth formwork has a locking part on at least one surface of which a rod-shaped body is attached and locked. It is characterized by the fact that it is provided.

両端を法面に打込んだアンカーピン８に係止する。FIG. 1 shows a state in which a fabric formwork 1 is laid on a slope 5. The fabric formwork 1 is laid with the vertical direction oriented in the vertical direction of the slope, and the horizontal direction oriented in the horizontal direction, and a plurality of rod-shaped bodies 6 (made of FRP, φ10
mm) are fixed at predetermined intervals. Formwork 1 at the same time
Three ropes 7 are arranged along the vertical direction on the upper surface of the rope, and both ends of the ropes are locked to anchor pins 8 driven into the slope.

Please attach it. The vertical and horizontal dimensions of the formwork 1 to be laid will shrink due to the filling of the aqueous slurry, so the formwork 1 is laid with an allowance for the shrinkage. is controlled by the horizontal dimension of the protective layer formed by filling the aqueous slurry. Further, the lengthwise dimension of the formwork 1 is regulated by locking and fixing the rope 7 arranged in the vertical direction with the rod-like body 6 and its intersecting portion.

護層が形成できる。When a water-based slurry 4 such as concrete is injected and filled from the top of the slope into the cloth formwork 1 whose dimensions in the vertical and horizontal directions are regulated in this way, the formwork 1 is sized in both the vertical and horizontal directions as shown in Figure 4. Since the dimensions are regulated, the slurry will not be packed with excessive slurry and bulge in some areas, or the vertical and horizontal dimensions will shrink significantly and become small. A protective layer with accurate horizontal dimensions and uniform beads can be formed.
上記実施例ではヨコ方向に棒状体、タテ方向にロープを

型枠寸法を規制してもよい。In the above embodiment, the rod-shaped body was arranged in the horizontal direction and the rope was arranged in the vertical direction, but the rod-shaped body was arranged and fixed in both the horizontal and vertical directions.
Formwork dimensions may be regulated.

ならない。Also, in some cases, the rod-shaped body is arranged and fixed only in the horizontal direction, and in the vertical direction, that is, in the vertical direction of the slope, the margin is pulled up in the upward direction of the slope, and as the slurry is filled, it is loosened little by little and then fed out. It's okay. However, it is more preferable to arrange a rod-shaped body, a rope, etc. also in the vertical direction to regulate the dimensions. A rod-like body must be attached and fixed at least in the horizontal direction, that is, in the horizontal direction of the slope, and its dimensions must be regulated.
この発明による布製型枠は少なくとも片表面に輪奈等の
棒状体を係止する係止部が設けである。従って、敷設し
た布製型枠に棒状体を容易に添付係止ができる。The cloth formwork according to the present invention is provided with a locking portion on at least one surface for locking a rod-shaped body such as a hoop. Therefore, the rod-shaped body can be easily attached and locked to the laid fabric formwork.
係止部は糸束あるいは織組織体がループ状に張出した輪
