[0002]

2. Description of the Related Art As the above-mentioned in-situ casting method frame construction method, for example, there is a "slope stabilization construction method" disclosed in Japanese Patent Publication No. 58-20338. In this method, after laying a mesh body such as a wire mesh on the slope, laying reinforcing bars on this mesh body in a grid pattern, spraying mortar or concrete (hereinafter referred to as mortar etc.) on this grid reinforcing bar and mortar Since it is designed to form a grid-shaped method frame made of, etc., it is superior in workability and strength compared to the conventional prefabricated type and in-situ method frame construction method, and it uses less equipment and is cheaper. There is an advantage.

[0003]

By the way, according to the current civil engineering standards, it is required that the thickness of the mortar or the like covering the grid-like reinforcing bars (which is called the covering thickness) is 5 cm or more from any surface of the reinforcing bars. Mandatory as a quality control standard for obtaining a strong grid-like framework. However, the cast-in-place method frame method is a cast-in-place method frame method that does not use a formwork, and since spraying mortar and the like is performed as site work in an unstable place on the slope, grid-shaped reinforcing bars are used. The thickness and width of the mortar sprayed against the surface are likely to be non-uniform, and considerable skill is required to form a grid-like method frame of a predetermined size, while avoiding variations in the size and strength of the grid-like method frame. I couldn't.

The present invention has been made in consideration of the above-mentioned matters, and in the in-situ casting method using no formwork,
An object of the present invention is to provide a cast-in-place method frame method capable of easily forming a lattice-shaped method frame made of mortar or the like having dimensions and strength according to specifications without requiring skill.

[0005]

In order to achieve the above object, the present invention is to lay a reticulated body on a slope, arrange rebars on the reticulated body in a grid pattern, and apply mortar or rebar to the grid rebar. In the cast-in-place method frame construction method in which concrete is sprayed to form a grid-like method frame made of mortar or concrete, an inspection frame including an arcuate member having a predetermined height and width and a connecting member connecting the arcuate members To
It is characterized in that mortar or concrete is sprayed in a state in which the arcuate members are arranged at appropriate intervals so as to straddle the reinforcing bars.

In this case, both lower ends of the arcuate member are bent to form a sunken portion, or a holding member for floatingly holding the reinforcing bar is detachably provided on the inspection frame. Further, the member forming the inspection frame may be formed of a wire that has been subjected to rust prevention processing.

[0007]

The inspection frame K used in the present invention is, for example, as shown in FIG. 4, two arcuate members 1 having a predetermined height H (for example, 10 cm) and a width W (for example, 30 cm), and these two arcuate members 1. It is composed of two connecting members 2 for connecting the arcuate members 1 to each other, and both end portions of the arcuate member 1 are bent, for example, in directions facing each other to form the sunken portion 4. The bow-shaped member 1 and the connecting member 2 that constitute the inspection frame K are made of rust-proof wire having an appropriate thickness, and they are connected by welding or soldering.

When forming the grid-shaped method frame 12 made of a predetermined mortar or the like on the slope, after shaping the slope 5, as shown in FIG. The body 6 is laid, and the reinforcing bars 8 are arranged on the mesh body 6 in a grid pattern. Then, as shown in FIG. 2, the inspection frames K are arranged at appropriate intervals so that the arcuate members 1 straddle the reinforcing bars 8, and thereafter, as shown in FIGS. Mortar or the like 11 is sprayed on the reinforcing bar 8 forming the.

By doing so, the mortar 11 or the like can be accurately sprayed onto the reinforcing bar 8 so as to have a predetermined width and height, and the grid-like method frame 12 made of mortar or the like having a predetermined strength is formed. The surface 5 can be reliably formed.

[0010]

1 to 4 show one example of the in-situ casting method frame construction method of the present invention. First, the inspection frame K used in the present invention will be described with reference to FIG. Figure 4
As shown in, the inspection frame K has a predetermined height H (for example, 10
cm) and a width W (for example, 30 cm), and two connecting members 2 for connecting the two arcuate members 1 at appropriate height positions,
It has a kamaboko-like shape. The bow-shaped member 1 and the connecting member 2 have an appropriate thickness (for example, a diameter of 4 m) that is rust-proofed.
m) of wire, and both ends of the connecting member 2 are fixedly attached 3 to a position slightly above the lower end of the arcuate member 1 by welding or soldering. In this embodiment, the lower end portions of the arcuate member 1 are bent in appropriate lengths (for example, about 5 cm), for example, in directions facing each other, and the sinking prevention portion 4 is formed.
Is formed. The length L of the connecting member 2 is determined by the slope 5
In addition, the length may be shorter than one side of the lattice frame formed by the reinforcing bars 8, for example, about 40 to 50 cm.

Next, an example of the in-situ casting method frame construction method using the inspection frame K will be described with reference to FIGS. For example, the slope of the pre-shaped slope 5 is 5 to 5
A mesh body 6 such as a diamond wire mesh of about 6 cm is laid and anchors 7 are driven into the slope 5 at appropriate intervals to fix the mesh 6 to the slope 5 (see FIG. 3).

A diameter of, for example, 6 to 10 is provided on the mesh body 6.
Reinforcing bars 8 having a size of about mm are combined and arranged in a grid shape having one side of about 1 to 2 m (see FIG. 1). An anchor 9 having a diameter of 16 mm and a length of 40 to 50 cm is provided at the intersection of the reinforcing bars 8.
Drive with 10 cm protruding from the slope 5
The reinforcing bars 8 are bound to the protruding portions of the anchors 9 by using an appropriate binding wire 10 (see FIGS. 2 and 3). It should be noted that an anchor (not shown) having a diameter of about 9 mm and a length of about 30 cm may be driven into the slope 5 between the intersections, and the reinforcing bars 8 may be bound to the anchors as at the intersections. .

Then, the inspection frame K is arranged on the mesh body 6 so that the arcuate member 1 straddles the reinforcing bar 8 at approximately the center of each side of the lattice frame composed of the reinforcing bars 8 (FIGS. 1 and 2). 2). Since this inspection frame K serves as a guide for the spraying width and spraying height of the mortar 11 and the like, it is sufficient to provide at least one on each side of the lattice frame. Length is 1-2 m, length L of inspection frame K is 4
When it is 0 to 50 cm, it is sufficient to provide one inspection frame K on each side. Further, when the length of the side becomes larger, two or more inspection frames K having the above dimensions may be provided, but the length L of the inspection frame K is made larger (for example, 1.3 to 1. 5m
It may be set. Furthermore, the inspection frame K may be provided over the entire length of the side.

In the grid-shaped reinforcing bar 8 constructed as described above, for example, a mortar of low slump having a water content of about 7 to 8%, etc. 1
1 is sprayed by a spraying machine for civil engineering (not shown) such as a mortar gun machine. In this case, since each side of the lattice frame formed by the reinforcing bars 8 is provided with an inspection frame K that serves as a guide for the spraying width and the spraying height of the mortar 11 or the like, the mortar or the like follows the inspection frame K. The grid-shaped method frame 12 made of mortar or the like having a predetermined size can be easily formed only by spraying 11. That is, in this embodiment, the grid-shaped method frame 12 made of mortar or the like having a lower end width of 30 to 35 cm and a height of 10 to 15 cm can be formed, and the grid-shaped method frame made of mortar or the like having a predetermined size and a predetermined strength can be formed. The frame 12 can be reliably formed. 1 and 3, reference numeral 13 is a nozzle for spraying the mortar 11 or the like.

In the lattice-shaped method frame 12 made of mortar or the like formed on the slope 5 as described above, soil, organic material,
To form a vegetation layer 14 (see FIG. 1) by spraying a vegetation material obtained by mixing a water retaining material (soil improving material) and seeds such as turf grass, wild grass and shrubs with a power spraying machine,
Instead of this, a vegetation bag (not shown) in which a coarse bag body is filled with the vegetation material is arranged to introduce vegetation into a rock slope, which has been conventionally impossible. It becomes possible to contribute to the improvement of the slope landscape and the permanent stabilization of the slope due to the roots and stems of vegetation.

The present invention is not limited to the above-mentioned embodiments, but can be modified in various ways. For example, as shown in FIG. 5, a holding member 15 having hook portions 15a and 15b at both ends is used, and one hook portion 1 of the holding member 15 is used.
5a may be engaged with the arcuate member 1, and the reinforcing bar 8 may be floated and held together with the net-like body 6 by the other hook portion 15b. In this case, it suffices that the holding member 15 is made of rust-proof wire, and further, each member is covered with the floating height of the reinforcing bar 8 so that the thickness becomes a specified value (5 cm or more). It is desirable to set the dimensions of.

FIG. 6 shows an embodiment in which only the reinforcing bar 8 is floated and held in the embodiment of FIG. In this case, when the vegetation layer 14 in the lattice-shaped method frame 12 is less than 5 cm, the net-like body 6 effectively acts as a runoff prevention material for the vegetation material as the spray base material.

Further, as shown in FIG. 7, the reticulate body 6 may be floated and held by using an appropriate spacer 16 so that the covering thickness of the reinforcing bar 8 becomes a specified value. The spacer 16 may be, for example, "Las spacer for slope protection" of the applicant's design registration application No. 4418 in 1988.
Alternatively, the “spacer pin” disclosed in Japanese Utility Model Publication No. 5-42118, which is filed by the applicant of the present application, can be used.

In any of the above embodiments,
Although the installation height of the connecting member 2 is arbitrary, it is desirable to fix it at a high position of the arcuate member 1 when the covering thickness of the reinforcing bar 8 is secured. Further, for example, the inspection frame K may be integrally formed of plastic. Furthermore, three or more arcuate members 1 may be provided. Further, the number of the reinforcing bars 8 provided on one side is not necessarily one, but a plurality of reinforcing bars may be used. In that case, four long anchors are driven into the slope 4 near the intersection of the reinforcing bars to form the reinforcing bars. It is also possible to bind the support to each other and stack them in one or several steps.

[0020]

As described above, in the present invention, after the reticulated body is laid on the slope, the reinforcing bars are arranged in a grid on the reticulated body, and the mortar or concrete is sprayed on the reticulated bar. In the cast-in-place method frame method to form the lattice method frame made of mortar or concrete,
In a state in which the inspection frame composed of an arcuate member having a predetermined height and width and a connecting member for connecting the arcuate members is arranged at an appropriate interval so that the arcuate member straddles the reinforcing bar. Since mortar or concrete is sprayed, uneven spraying of mortar etc. is eliminated,
It is possible to easily form, on the slope, a lattice-shaped method frame made of mortar or the like having a predetermined covering thickness around the reinforcing bars and having dimensions and strength according to the standard.

When the sinking prevention portion is formed on the arcuate member, it is possible to prevent the inspection frame from sinking even when the slope is formed by embankment. The grid-shaped method frame can be reliably formed to have a predetermined size.

Further, in the case where the holding member for holding the reinforcing bar in a floating manner is detachably provided on the inspection frame, the holding position of the reinforcing bar is more reliably performed.
