Abstract

PROBLEM TO BE SOLVED: To easily and safely protect a slope by continuing and connecting a form in which a cross space is partitioned by a wire netting, and a spacer, a reinforcement and a cylinder are arranged and integrated within the space, and filling a consolidating material into the form to constitute a slope frame. SOLUTION: An L-shaped wire netting single body 41 is stood at prescribed intervals to partition a cross space, and a reinforcement 43 is integrally supported to a spacer 42. The continued body of such a cross form 4 is set in parallel crosses on a leveled slope 9, and an anchor body 46 is driven into a cylinder 45 within the form 4 to fix the form 4 to the slope 9. The end parts of the forms 4 set and fixed in parallel crosses are mutually connected by an optional means, and a consolidating material 10 such as mortar or concrete is filled into the form 4. A slope frame 3 can be closely set on the slope 9 as the whole by the weight of the consolidating material 10. After the consolidating material 10 is consolidated, the anchor body 46 is fastened to bind the slope frame 3 to the slope 9.

[0011]

The construction method using the formwork according to the present invention will be described below with reference to FIG. The method according to the present invention comprises the cross-shaped form 4, the T-shaped form 5,
The L-shaped formwork 6, the Y-shaped formwork 7, and the I-shaped formwork 8 can be used individually or in combination with each other. Will be described.

<Leveling of Slope> In order to install the cross-shaped formwork 4 on the slope 9, the slope 9 is leveled. In the case where the lawn frame 3 utilizing the natural terrain is used, it is only necessary to level the portion where the cruciform frame 4 is to be installed and where the irregularity is severe.

<Installation of cross-shaped formwork> Leveled slope 9
Then, the cross body 4 is set so that the continuum of the cross-shaped frame 4 is in a cross-girder shape. When the cruciform form 4 is installed on the slope 9, if the familiarity with the slope 9 is not good, fine adjustment of the leveling is performed along the part where the cruciform form 4 is in contact with the slope 9. If you go, cross-shaped formwork 4
Can be installed well on the slope 9.

<Putting Anchor Body> An anchor body 46 is driven into a cylinder 45 installed in the cruciform frame 4, and the cruciform frame 4 is fixed to the slope 9. When selecting the structure of the anchor body 46, it is necessary to examine the geology of the slope 9 in advance, and to consider the structure of the anchor body 46, the depth of insertion, and the like.

<Coupling between Formwork> The ends of the cross-shaped formwork 4 arranged and fixed in a cross-girder shape are connected by any method such as welding or bundling.

<Filling of the binding material> The binding material 10 such as mortar or concrete is filled into the inside of the cross-shaped mold 4 by a known method. Since the cruciform form 4 is previously set well on the slope 9, the weight of the stiffener 10 further increases the form 3
It is installed on the slope 9 as a whole.

<Tightening of anchor body> After the sintering material 10 is solidified, the anchor body 46 is tightened, and the sloping frame 3 is tightened to the slope 9.

[0018]

Since the present invention has been described above,
The following effects can be obtained. <A> Since a single formwork is used, it can be transported lightly and in large quantities. <B> Since a single formwork pre-fabricated at the factory is used, no formwork assembly work on site is required. <C> Since only a single formwork needs to be arranged on the slope, no skilled person is required. <D> Easy and safe work can be performed even on an inclined surface with poor scaffolding. <E> By using a combination of single forms of various shapes, it is possible to create legal frames of various shapes that take advantage of the topography of the site Can be built.
