Abstract

PURPOSE: To improve the construction accuracy and efficiency of a slope frame by assembling a form consisting of a pair of plate bodies which have a reinforcement arranged on a slope and are mutually opposite and a sheet-shaped body hanging down from the lower end of the plate body between the plate bodies, and joining the sheet- shaped bodies to fill up a solidifying agent between them. CONSTITUTION: A pair of opposite plate bodies 1 is mutually connected through a connecting member 2, and a sheet-shaped body 3 severally hangs down from the lower end of the plate body. A joining part 31 for mutually joining the sheet-shaped bodies 3 is provided on the side of the free end of the sheet-shaped body 3. Next, a reinforcement 4 is installed at the prearranged construction position of the slope frame on a slope and fixed by anchors. After assembling the reinforcement 4, the form is set so as to cover the reinforcement 4. In this case, the reinforcement 4 is fitted between the vertical members 22 of the connecting members 2 for securing the fixed reinforcement covering thickness of a solidifying agent 6. The joining parts 31 of the sheet- shaped bodies 3 are joined to form a bag-shape. After that, the solidifying agent 6 is filled up by placing or spraying. Thus labor saving in the execution of the slope frame and the improvement of safety can be attained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a method frame and a formwork for method frame construction for stabilizing slopes.

[0002]

2. Description of the Related Art Conventionally, there is a method as shown in FIG. 5 as a method of constructing a method frame for stabilizing a slope. In this method of constructing a frame, a bag-shaped sheet having micropores between the lower portions of a pair of opposing plate frames a to the extent that a solidifying material such as concrete exudes.
After installing the form frame configured by mounting the toe b on the slope,
The reinforcing bar c is assembled between the plate frames a, and the solidified material d is placed therein. According to this method, since the bag-shaped sheet b is attached to the lower portion of the plate frame a, the solidified material d is prevented from flowing out from the gap between the lower end of the plate frame a and the ground surface. In addition to being prevented, the solidified material d exudes from the bag-shaped sheet b, so that the method frame after solidification can be reliably bonded to the ground surface.

[0003]

The above-mentioned prior art uses a mold having a shape in which two plate frames a are connected by a bag-like sheet b. Therefore, after the mold is installed on the slope, Without it, the reinforcing bar c cannot be assembled. However, since a gap is formed between the lower end of the formwork and the ground surface on the uneven slope, the installation position of the formwork is likely to shift during work, and the reinforcing bar c assembled based on the formwork position is used as a reference. The assembly position also shifts. Therefore, the accuracy of construction of the legal framework will be reduced. In addition, the work of assembling the reinforcing bars c in the narrow space between the plate frames a is complicated, which leads to a decrease in construction efficiency.

[0004]

The sheet-like material 3 is hung down, and a joint portion 31 for joining the sheet-like materials is provided on the free end side of the sheet-like material 3.

The plate 1 includes a wire mesh, a perforated iron plate, and a concrete
A sheet plate or the like is used, and when these are used, the sheet material 3 and the sheet-like material 3 are buried in the solidified material. When plywood or the like is used, it is removed after the solidifying material is solidified, but the sheet-like material 3 may be buried.

The connecting member 2 has, for example, a pair of plate members 1 at both ends.
And a vertical member 22 joined to the horizontal member 21 with a width interval between the reinforcing bars to be assembled on the slope.
And consist of. Then, a suitable number of the connecting members 2 are mounted between the opposing plate members 1 so that the two plate members 1 can be opened and closed so that the mold can be folded. The vertical member 22 may not be provided.

As the sheet-like material 3, there is used one having fine pores to the extent that a solidifying material such as concrete oozes out. For example, fiber cloths such as polypropylene, fine fishnets,
Flexible wire mesh can be used.

The joint portion 31 formed on the free end side of the sheet-like material 3 is, for example, a magic tape, a chuck, a belt,
A hook or the like can be adopted.

<B> Assembly of Reinforcing Bars First, as shown in FIG. 3, the reinforcing bars 4 are accurately installed at the planned position for constructing the method frame on the slope, and fixed on the slope by the anchors 5.

<C> Installation of Form After the assembly of the reinforcing bar 4 is completed, as shown in FIG. 3, the form constructed as described above is installed so as to cover the reinforcing bar 4. At this time, by fitting the reinforcing bar 4 between the vertical members 22 of the connecting member 2, the distance from the plate body 1 to the reinforcing bar 4 can be kept constant, so that the reinforcing bar covering thickness of a predetermined solidifying material can be secured. You can Next, as shown in FIG. 1, the joining portions 31 of the two sheet-like objects 3 are joined between the plate bodies 1 to form a bag.

[0014]

Operation of Embodiment 1 As described above, since the sheet bodies 1 are connected by the sheet-like material 3 and the solidifying material 6 is filled from above the sheet-like material 3, the ground surface and the plate body are filled. It is possible to prevent the solidified material 6 from flowing out by closing the gap generated between the lower end portion 1 of the sheet 1 and the sheet-like material 3. Further, since the solidified material 6 exudes from the sheet-like material 3, it is possible to achieve reliable adhesion between the solidified method frame and the ground surface.

[0015]

[Embodiment 2] In Embodiment 1, the construction is carried out by joining the free ends of the longer sheet-like material 3 to each other, but a short sheet-like material 7 as shown in FIG. 4 is used. It is also possible to use a mold attached to the lower end of each plate 1.

In this case, both sheet-like materials 7 are folded between the plate bodies 1 and arranged without being fixed on the slope, and the sheet-like material 7 folded by the spraying force of the solidifying material 6 is placed on the slope. In the pressed state, the solidifying material 6 is sprayed into the mold.
