[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for protecting a slope, and more particularly to a slope protection structure which is easy to construct and has a large structural strength.

[0002]

2. Description of the Related Art The inventor of the present invention discloses the invention of Japanese Examined Patent Publication No. 61-9451. According to the invention, a mold is constructed by using two dam plates having an L-shaped cross section, which are molded from expanded metal or the like. That is, one side of each weir plate is overlapped, the overlapped part is formed along the ground to form a groove-shaped formwork, and a cement-based hardening material is cast on the formwork to construct a structure. is there. The L-shaped dam plate is easy to stack and transport, and the overlapped part becomes a tensile steel material that can withstand the tensile force that acts on the structure when the slope collapses. It becomes a protective structure with high structural strength. Is.

[0003]

As described above, the above-mentioned prior art has extremely great advantages, but it has been desired to develop a structure for developing this and further facilitating the construction.

The present invention has been made in order to solve the above problems, and an object thereof is to provide a slope protection structure which can be easily constructed and has a large structural strength.

[0005]

In the slope protection structure according to the present invention, a mold having a groove-shaped cross section is formed by two dam plates having an L-shaped cross section, and an overlapping portion is pressed by an anchor having a pressing portion. It is to fix both weir boards. That is, a pressing portion is projected at an intermediate portion in the vertical direction of the anchor, and the anchor is passed through the overlapping portion of the two dam plates formed by the mesh member, and the overlapping portion is pressed by the pressing portion. The part of the anchor projecting from the ground is used as the guide of the reinforcing bar placed in the formwork.

Since the fixing of the left and right weir plates is completed at the same time when the anchors are driven, the construction is remarkably easy. The guide portion also facilitates rebar arrangement.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on an embodiment shown in the drawings. In the drawing, reference numeral 1 is a weir plate and has a cross section L.
It is shaped like a letter. The barrier plate 1 may be any mesh member, and various members such as a porous metal plate other than the expanded metal and the crimp wire mesh can be adopted. This dam plate 1
Are used, and one surface of each is superposed to form a mold 2 having a groove-shaped cross section. The overlapping margin of the barrier plates 1 and 1 can be changed according to the width and strength of the structure. Narrow width metal corner members 5, 5 are welded along the tips of the weir plates 1, 1 which are the top ends of the groove-shaped cross section.

In the figure, 3 is an anchor, which is made of a metal rod. A pressing portion 4 is provided so as to protrude from the upper and lower intermediate portions of the anchor 3. In the embodiment shown in FIG. 1, the holding portion 4 fixed by welding is projected to one side,
The holding portion 4 of the embodiment shown in FIG. 2 projects to the left and right sides. Further, the pressing portion 4 of the embodiment shown in FIG. 3 projects like a collar around the periphery. Alternatively, a nut can be screwed into the anchor 1 having the external thread cut off, and this nut can be used as the holding portion 4.

The anchor 3 is passed through the overlapping portion of the mold 2 and is driven into the natural ground. Since the dam plate 1 is made of a mesh member, it can be driven through the mesh and holes, and the construction is easy. The anchor 3 is pushed down as it is, and the weir plate 1 is pushed by the holding portion 4.
・ Hold the overlapping part of 1. This completes the fixing of the barrier plate 1.1.

The portion of the anchor 3 protruding from the natural ground is erected at the left and right intermediate portions in the frame 2 having a groove-shaped cross section, and this is used as a guide portion 6 of the reinforcing bar 7. The reinforcing bars 7 are arranged in the form 2, and the reinforcing bars 7 are positioned along the guide portions 6. Further, in some cases, the reinforcing bar 7 is bound to the guide portion 6. In this state, a cement-based hardening material 8 of concrete or mortar is placed in the mold 2. The corner materials 5, 5 make it easy to level the cement-based hardening material 8.

[0011]

The present invention has the above-mentioned structure, and an anchor having a holding portion is passed through an overlapping portion of a groove form made up of two dam plates, and the anchor is driven by the holding portion. At the same time, since the dam plate can be fixed, the construction can be extremely simplified. In addition, the guide portion facilitates rebar arrangement, which also simplifies construction. The overlapping portion of the two dam plates has a large tensile strength, and can effectively withstand the tensile force that acts due to the collapse of the slope,
The structure has high structural strength. It is easy to stack a large number of L-shaped dam plates during transportation, is not bulky, and can be transported in large quantities without waste. By changing the overlapping margin of the left and right weir plates, a structure of any size can be constructed.
