本考案は、法面を保護するコンクリート法枠構
造物の施工にあたつて使用する埋込型枠の巾止材
に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a blocking material for embedded forms used in constructing concrete slope structures for protecting slopes.

In the slope construction method, which is one of slope protection works, embedded formwork such as a mesh is erected on the slope surface, and concrete such as concrete or mortar is poured between the formwork.
It is practiced to bury a formwork therein (for an example, see Japanese Patent Publication No. 53-32166).

By the way, a legal frame is generally formed in a lattice shape with column-shaped items that are long in the vertical direction of the slope and beam-shaped items that are long in the transverse direction of the slope. When constructing a structure, as concrete is poured, the pressure due to the concrete's own weight will be greater at the lower part, causing a significant amount of concrete to escape from the mesh of the mesh formwork. As a result, it becomes impossible to form a legal frame with a predetermined shape, and a large amount of concrete is wasted, leading to a corresponding increase in construction costs.

供しようとするものである。 This invention was made to improve the shortcomings of the conventional frame construction method as described above, and allows for easy and reliable spacing of embedded formwork, as well as reducing the pressure of concrete placed at the bottom of the frame. The purpose of the present invention is to provide a blocking material for embedded formwork that can reduce construction costs by reducing concrete from escaping from the slope.

It is installed protrudingly. In addition, clamping bodies 3 are provided at both ends of the width stopper 1 to be coupled to the formwork. This clamping body 3 is formed to be long in the transverse direction of the width stopper 1, that is, in the direction orthogonal to the widthway stopper 1, and has a downward opening that engages with a member at the upper edge of the formwork, which will be described later. An engagement groove 4 is provided throughout the entire length, and opposing squeezing portions 5 protruding inward are formed at the open end thereof. It is preferable that each of the stopper rods 1, the resistor 2, and the clamping body 3 be integrally molded from a highly corrosion-resistant synthetic resin.

次に、前記の本考案巾止材による施工態様につ

The shaft bars 7, 7 are vertically arranged in parallel at intervals,
It is formed by the axial reinforcements 7 and a net-like body 8 disposed between them. This formwork 6 is molded and hardened using a material in which a bundle of lightweight and high-strength fibers is impregnated with a highly corrosion-resistant resin material. The fibers are bound together in a state in which they intersect with each other, and the axial reinforcement 7 is thick and the net-like body 8 is thin. As the fibers mentioned above, glass fibers, carbon fibers, etc. are suitable, and as the resin material for binding these fibers, vinyl ester resins etc. are suitable. If the formwork 8 provided with such axial reinforcements 7, 7 is used, the formwork 8 can be assembled immediately by placing the reinforcements, and construction can be greatly simplified.

ーフローすることを防止することになる。 To construct a legal framework structure on a slope, as shown in FIGS. By passing the width restraining material of the present invention between the edges, attaching the lower surfaces of the clamping bodies 3, 3 to the shaft reinforcement 7 on the upper edge of the formwork 6, and pressing down the clamping body 3, the clamping material can be compressed. The engagement groove 4 and the shaft reinforcement 7 fit together through the portion 5. Thereby, the formworks 6, 6 are held at a predetermined distance at their upper edges by the width stopper of the present invention. In addition,
If necessary, a conventional width stopper 10 as shown in the figure is installed on the shaft reinforcements 7, 7 below the formworks 6, 6.
Furthermore, the width stopper material of the present invention can be used instead of the width stopper material 10. In this case, the resistor 2 is preferably directed upward. The formworks 6, 6 are held by the stopper material at appropriate intervals in the length direction of the formwork 6, and the formworks 6, 6 are fixed on the slope by anchor materials (not shown). Ru. After that, concrete 9 such as concrete or mortar is poured between the formworks 6 and 6.The poured concrete 9 flows downward from the placement position and is poured between the formworks 6 and 6. Although it will be filled, the formwork 6, 6
Since the resistors 2 of the blocking material are protruded at various places between them, they act as a resistance and reduce the excessive pressure caused by the concrete 9 flowing down. Excessive leakage of the concrete is prevented, and the concrete placed in the formwork 6 is also prevented from swelling to the top surface due to its own weight and overflowing.

As explained above, the formwork stopper material of the present invention is
A resistor is formed at both ends of the width stopper extending downwardly in the transverse direction of the width stopper, and
Since the clip is provided with a clamping body that opens downward and has an engagement groove for the upper edge of the embedded formwork, the binding material and the formwork can be easily connected by simply fitting them together. It is easy to set the form spacing and connect the formwork to each other, and since the resistor acts against the pouring of concrete, it prevents concrete from flowing through the formwork due to the pouring pressure of the concrete. Excessive leakage of water and overflow of the top surface caused by its own weight can be prevented, and construction costs can be reduced. In addition, when the pressure of concrete is applied to the resistor, the blocking material is connected to the formwork by a long clamping body formed in the length direction of the formwork, so it does not separate and is used for its purpose. It has many advantages, such as the ability to achieve
