Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork device for a method frame for constructing a closed method frame on a part of the slope.

[0002]

2. Description of the Related Art Slope protection technology has been variously developed with emphasis on its function and protection strength. There is a mortar spraying method that covers the entire slope with a mortar lining layer in the old days, but it has been pointed out that this method damages the landscape. Considering this harmony with the surrounding landscape, a technique for greening the mortar lining layer has been proposed in JP-A-747424, JP-B-3-6284, and JP-B-3-68174. ing. In these proposals, a large number of anchor pins with blades attached to the upper part are driven into a slope of this kind, and then a vegetation base material mixed with seeds and fertilizer is sprayed, and a large number of layers of vegetation base material are applied to a group of blade plates. It supports the (vegetation base) and greens the entire slope. However, these greening methods have a drawback that a large amount of anchor pins with blades and vegetation base materials are required.

Further, a folding type formwork for a formwork is used in which gate-shaped spacers are connected between strip-shaped wire nets arranged opposite to each other, and a plurality of formwork is formed on the slope. A slope protection method is known in which, after laying in a pattern, reinforcing bars are arranged inside the formwork, and a consolidating material is sprayed to such an extent that the formwork and the reinforcing bars are hidden to construct the formwork on site. This type of formwork can be applied to a straight-line formwork, but it cannot be used when the formwork is a curved form such as a circle or an ellipse.

Further, a formwork has also been proposed which is constructed by separating a pair of wire mesh and a spacer. This formwork has a structure in which foldable spacers are attached to a pair of wire meshes, and an opening at the free end of the spacer is hooked on a reinforcing bar laid on the slope to assemble. However, in this formwork, one end of the spacer made of a wire material is wound around the wire mesh, and the other end of the spacer is formed with an opening that can be inserted into the reinforcing bar, so that a lot of labor and labor are required for processing the spacer. In addition to the above, the spacer attached to the wire mesh hinders an operator from being injured or tearing clothes during handling, or when the wire mesh is stacked and stored and transported.

The present invention has been made in view of the above points, and it is an object of the present invention to deal with whether the legal frame shape is a curved shape or a linear shape, and which is excellent in assembling operability. It is to provide a formwork device for a frame.

Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

<A> Formwork Device FIG. 1 is a perspective view of a frame device 1 having an arc shape. The formwork apparatus 1 is composed of a reinforcing member 2 and a pair of inner and outer band molds 3 and 4 which are retrofitted on both sides of the reinforcing member 2 on site.

<B> Reinforcing Material The reinforcing material 2 is composed of a plurality of main bars 5 formed by bending different diameter steel bars into an arc shape.
And a gate-shaped spacer 6 provided at a predetermined interval along the longitudinal direction of the main bar 4. As shown in FIG. 2, the spacer 6 functions as a support member for the plurality of main bars 5,
It is a member that also has a function of holding a pair of band forms 3 and 4 at a constant interval, and intersects a plurality of horizontal lines 7 and a plurality of vertical lines 8 and 8 and fixes each intersection by welding or the like. Are formed in a substantially cross beam shape, and the main bar 5 is arranged at the intersection of these lines 7 and 8. The vicinity of the ends of the horizontal lines 7, 7 is bent at a right angle, and the linear portion is further bent in a U shape to form a hook 9. The reinforcing member 2 has a characteristic structure in that a belt form 3, 4 and a hooking portion 9 that can be hooked are formed on the main bar 5 side. still,
In this example, the case where the opening of the hooking portion 9 faces upward is shown, but it goes without saying that the opening may face downward.

<C> Belt form frame The band form frames 3 and 4 are made of, for example, a net material such as a wire net, a lath wire net, or a flexible resin, metal, a wooden perforated plate or a non-perforated plate, The length is set to be equal to that of the reinforcing material 2 described above.
Considering workability and handleability, it is desirable to use a crimp wire mesh that is knitted by intersecting vertical and horizontal lines. Further, when the belt form frames 3 and 4 are non-perforated plates, it is necessary to provide an opening at a position where the spacer 6 is hooked with the hooking portion 9. An important point of the strip frames 3 and 4 is that an opening capable of engaging with the engaging portion 9 is formed at least at an engaging position with the spacer 6. Moreover, when the both ends of the formwork apparatus 1 are joined and used as in the present embodiment,
An extra length portion 10 in which the spacer 6 does not exist is formed at the end portion of each of the band forms 3 and 4. The extra length portion 10 serves as a portion to be overlapped with the other band forms 3 and 4. In addition, there are two methods for bending the band forms 3 and 4 at the factory, such as bending at the curvature of the reinforcing material 2 and bending at the time of assembly to the reinforcing material 2. It is of a nature to be selected in consideration of the situation and the like.
