[0006]

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

<A> Overall Configuration FIG. 1 shows a formwork for a legal form according to the present invention (hereinafter referred to as "form form").
1 shows an example of a concrete method frame 3 constructed on a slope 2 by using FIG.

<B> Formwork FIG. 2 is a perspective view of the formwork 1. The mold 1 has an L-shaped overall shape, and includes first and second inner frames 3 and 4 orthogonal to each other.
First and second frames which are respectively opposed to the inner frames 3 and 4
It is composed of outer frames 5 and 6 and a plurality of spacers 7 extending between the frames 3 and 5 and between the frames 4 and 6. For these frames 3 to 6, wire mesh, expanded metal, perforated plate or the like can be used, and there is no particular restriction on the material.

Regarding the relationship between the lengths of the respective frames, the total lengths of the first inner frame 3 and the first outer frame 5 facing each other are set to be equal, and the second inner frame 4 and the second outer frame 6 facing each other are similarly set. Are set equal, and a frameless opening 10 is formed between the first outer frame 5 and the second outer frame 6.

In this embodiment, the middle of one frame is bent at a right angle to form a first inner frame 3 and a second inner frame 4, and the joining angles of these inner frames 3 and 4 are set in advance. A case where this angle does not change will be described. The reason why the joining angles of the inner frames 3 and 4 are set in advance is to finish the legal frame neatly.

<C> Spacer The spacer 7 functions as a connecting tool for connecting the outer frames 5 and 6 to the inner frames 3 and 4 so as to be foldable, and the facing distance between the frames 3, 5 and 4 and 6. FIG. 3 to FIG. 5 show an example of a member having both a function of restraining the infiltration of each of the frames 3 to 6 while maintaining a constant value and a function of positioning the reinforcing bar 8 which is a reinforcing material of the frame.

In FIG. 3, wires are arranged in a cross-girder shape, their intersections are welded, and both ends of upper and lower horizontal lines 7a and 7b are rotatably connected to respective frames 3, 5 (4, 6) facing each other. FIG. 4 shows a spacer 7 which is formed by being connected. FIG. 4 shows the center of the lower horizontal line 7b divided to form an opening 7c therebetween, and a reinforcing bar 8 is fitted to the end of each of the divided lower horizontal lines 7b. FIG. 5 shows a spacer 7 capable of forming the accommodating receiving portions 7d, 7d and covering the formwork 1 with the reinforcing bar 8 assembled in advance, and FIG. And a receiving portion 7d, into which the reinforcing bar 8 can be fitted at the end of each of the divided upper horizontal lines 7a, 7a.
7d shows a spacer 7 having a structure in which the reinforcing bar 8 can be post-assembled after the mold 1 is laid in advance. The spacer 7 is not limited to the above-described form, and various known forms can be applied.

[0013]

Next, a method of constructing a method frame using the formwork 1 will be described. However, in the description, since the time and arrangement of the reinforcing bars 8 differ depending on the structure of the spacer 7, the description of the reinforcing bars will be omitted. .

As shown in FIG. 6, the folded form 1 is carried into the site by bringing both outer frames 5 and 6 closer to the L-shaped inner frames 3 and 4. Then, as shown in FIG. 7, the form 1 in which the outer frames 5 and 6 are unfolded at the site is brought into contact with the frame ends of the existing forms 1a, 1b and 1c, respectively. The connection coil 9 is rotated from above and connected.

That is, in the arrangement shown in the figure,
The left end of the first inner frame 3 of the mold 1 is joined to the upper end of the second outer frame 6 of the existing mold 1b, and the left end of the first outer frame 5 of the mold 1 is similarly connected to the left end of the existing mold 1a. 2 While joining to the lower end of the outer frame 6,
The right end of the first outer frame 5 of the mold 1 is joined to the lower end of the second inner frame 6 of the existing mold 1c, and the mold 1 is assembled in a cross-girder shape.
When laying the formwork 1, only three points need to be connected to the existing formwork.

After the work of laying and arranging the formwork 1 is completed, a molding material such as mortar is sprayed on the formwork 1 to construct a method form 3 as shown in FIG.

[0017]

[Embodiment 2] FIG. 9 shows another embodiment in which the combination of the laying of the formwork 1 is changed. In this example, the openings 10, 10 of the pair of molds 1, 1 are abutted, and the first and second
The butting portions of the outer frames 5, 6 (or between 5, 5 and 6, 6) are connected at two places of the connecting coil 9, and the frames 3, 5 (4, 4) of the existing molds 1d, 1e are connected. The end of step 6) and the abutting portions of the frames 3, 5 (3, 5) of the mold 1 are connected by connecting coils 9, respectively, to assemble the mold in a cross-girder shape. In the present embodiment, it is only necessary to connect two points when connecting the intersections of the formwork, and there is an advantage that the number of connection points of the intersections can be reduced as compared with the first embodiment.

[0018]

Third Embodiment FIG. 10 shows another form 1 in a folded state. In this example, the first inner frame 3 and the second inner frame 4
Are connected by a connecting coil 9 or the like so as to be freely foldable, whereby the form 1 can be folded compactly, which is convenient for storage and transportation.

[0019]

According to the present invention, the following effects can be obtained.

<A> An L-shaped form can be combined to form a cross-shaped form.

<B> When a conventional mold in which a pair of frame bodies are opposed to each other is used, a total of four
It is necessary to connect the points, but if an L-shaped formwork is used, the number of connection points at the intersections of the legal frames can be reduced, and the workability is excellent.

<C> Since the joining angle of the first and second inner frames is set to a right angle in advance, a beautifully beautiful legal frame can be constructed.

<D> If the joints of the first and second inner frames are foldably connected, the form can be folded compactly, so that the space for storing and carrying characters can be reduced.
