Further, both ends of _a second horizontal streak (c _a , c _b ) rotatably supporting the axial streaks (d ₁ , d ₂ ) are welded to the both side streaks (a, b) to form _a first horizontal streak. (C ₁ , c ₂ ...) Or the second horizontal streak (c _a , c _b ) is formed with an engaging portion for rotatably supporting the shaft streaks (d ₁ , d ₂ ); These two axis muscles (d ₁ ,
d ₂ is the) welded by weld (2, 2 a lower end of the vertical line (e _1, e ₂ ...) for each desired interval, these vertical stripe (e _1, e ₂ ... ) At the ends and at the center, the reinforcing members (f ₁ , f ₂ , g ₁ , g ₂ ) extending in parallel with the above-mentioned two side bars (a, b) are respectively welded portions (3, 3,..., 4, 4). ..) And the above-mentioned vertical streaks (e ₁ , e ₂ ...) And streaks (f ₁ , f ₂ ,.
g ₁ , g ₂ ) and shafts (d ₁ , d ₂ ) are integrally rotatable outward. Claim 2 of the present invention is that the upper end of _one longitudinal streak (e ₁ ...) Is attached to the other longitudinal streak (e _2.
.) And the other vertical streak (e)
Muscle (f ₁ of the upper end portion of the ₂ ...) is f _2, ...) and those formed by providing a hook (h ₁₎ that engages.

[0005]

In the first aspect, the axial muscles d ₁ and d ₂ are the second horizontal muscle c.
_The shafts d ₁ and d ₂ are held at a fixed distance by being engaged with the bearings 5 and 6 of _a and c _b or the engaging portions formed by bending. Normally, longitudinal streaks e ₁ , e ₂ ..., Streaks f ₁ , f ₂ , g ₁ , g ₂ are replaced by axial streaks d ₁ ,
Tilt outward by the d ₂ in the center, is transported in the flat shape as a whole. For the next use, the vertical stripes e ₁ , e _2.
・ The muscles f ₁ , f ₂ , g ₁ , g ₂ are turned around the axis muscles d ₁ , d ₂ to stand upright. According to claim 2, in muscle f ₁ of the upper end thereof for holding between the muscle f _1, f ₂ engages the hook h ₁ at a fixed distance.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Each braided frame has a different diameter of 10mm or 13mm (the surface has ring-shaped irregularities). Cut an iron rod into appropriate dimensions, weld the rebar in advance in a factory etc. by arc welding or spot welding, etc. and assemble it. Is designed to be horizontally foldable as an axis.

As shown in FIG. 3, both ends of a plurality of first horizontal streaks c ₁ , c ₂ ... Are alternately welded to a pair of parallel side streaks a, b at upper and lower sides at desired intervals. , And two axial bars d ₁ , d ₂ parallel to the two side bars a, b are outwardly provided at the center of the first horizontal bars c ₁ , c ₂ ,. Insert to rotate. Also the both sides muscle a, the b are welded to both ends of the second lateral stripes c _a to be engaged with the axial reinforcement d _1, d _2. The second horizontal strip c _a first lateral stripes c _1, c ₂ · · ·
May be any second horizontal strip c _a a, also, FIG. 3
As shown in ( ₁₎ , the vertical streaks e ₁ and e ₂ of the vertical frame may be provided independently and separately.

[0008] While the embodiment of FIG. 1 (a) is attached to the bearing 5 and 6 are engaging portions for rotatably engaged and supported the Jikusuji d _1, d ₂ to the second horizontal strip c _a, engaging The joining portion is not limited to this, and the portion where the axial streaks d ₁ and d ₂ engage as shown by a horizontal streak c _b in FIG.

The two axial muscles d ₁ , d ₂ have longitudinal muscles e ₁ ,
e ₂ ... of the lower end is welded by welds 2, 2 for each desired interval, these vertical stripe e _1, e _2, ... of the upper portion and the both side muscle a in the central portion, b Muscle f ₁ extending parallel to
f ₂ , g ₁ , g ₂ are respectively welded parts 3, 3,.
・ Weld by

On the other hand, the upper end h of the vertical stripe e ₂ is bent horizontally towards the vertical stripe e _1, when the upright vertical streak e ₁ is at its end, muscle f ₁ of the end portion providing hook h ₁ to be engaged. Since the present invention has such a configuration, the configuration of FIG.
As shown by the vertical lines, vertical streaks e ₁ , e ₂ ..., Streaks f ₁ , f ₂ , g
_{If 1} and g ₂ are tilted outward with respect to the axial muscles d ₁ and d ₂ as shown by the dashed line x ₁ , they will be the side muscles a and b, the first horizontal muscle c ₁ ,
as a whole becomes a planar overlap in the same plane as the c ₂ ···, it is convenient to transport.

In order to use this, first, a trench 10 is dug in the soil as shown in FIG. 4 (a), a gravel 11 is laid on the bottom as shown in FIG. Upper side muscle a,
b, the first horizontal stripes c ₁ , c ₂ ... are placed and the vertical stripes e ₁ , e ₂ ..., and the stripes f ₁ , f ₂ , g ₁ , g ₂ are aligned with the axial stripe d as shown by the solid line in FIG. _1, d ₂ in the central upright by rotating the to engage the hooks h ₁ muscle f _1. This results in streaks f ₁ , f
The ₂ held therebetween at a distance by the upper end h of the vertical stripe e _2. In the case where the vertical line e ₁ without the upper h and hook h ₁ of the horizontal, another hairpin muscle H muscle f _1, engage the f ₂ are two longitudinal muscle e ₁ shown in FIG. 6, e ₂ Is kept at a constant distance between the upper ends of the. Note when uprighting the vertical stripe e _1, e _2, first a vertical line e ₁ rotated to the chain line x ₂ in Figure 2, then the vertical stripe e ₂ a dashed line x ₃
Muscle f ₁ when rotated to the position enters the inside of the hooks h _1, Ryotatesuji e _1, e ₂ muscle f ₁ when the upright a engages naturally hook h _1.

L-shaped streaks (not shown) are applied to the vertical streaks f ₁ , f ₂ , g ₁ , g ₂ orthogonal to each other at the orthogonal portion of the groove 10, and these are strung with wires, strips, or the like. Band together. Next, as shown in FIG. 4C, a formwork 9 is assembled on both sides of the groove 10 and concrete 8 is poured into the mold 9 and hardened to form a foundation.

FIG. 7 shows another embodiment of the present invention.
The second lateral streaks a ₁ and b ₁ are further provided outside the lateral streaks a and b, and the first lateral streak c ₂ and the lower lateral streaks a ₁ and b ₁ are located below the side streaks a ₁ and b ₁ .
The extensions of c ₄ , c _6, ... are welded, and the extensions of the second horizontal streaks c _a , c _b are also welded below the side streaks a ₁ , b ₁ .

[0014]

As described above, according to the first aspect of the present invention, two sets of vertical streaks e ₁ , e ₂ ... And streaks f ₁ , f ₂ ,.
Since g ₁ and g ₂ stand upright, there is strength and axial muscle d ₁
, D ₂ are maintained at a constant distance by the second horizontal streaks c _a , c _b , and according to the invention of claim 2, first the vertical streaks e
₁ rotates up to a chain line x ₂ in Figure 2, then the muscle f ₁ when rotating the vertical line e ₂ to the position of the chain line x ₃ enters inside the hook h _1, the Ryotatesuji e _1, e ₂ When upright, the muscle f ₁ naturally engages with the hook h ₁ ,
The vertical stripes e ₁ and e ₂ are stably held in the upright state. Further, since the present invention can be easily folded and folded, it is easy to carry, and in the field, only the vertical bars and the connecting bars are pivoted around the shaft to make them vertical. The work of cutting and bundling can be saved, and since each part is welded, the strength and strength of the bundling material can be reduced as compared with the conventional brace.
