Embodiment 1 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 2 shows the connector 1. Using a galvanized steel sheet having a thickness of 3 mm, the bottom plate 11 is formed to form a square tubular body 10 having a square planar shape, that is, a square box body without a lid. The side plate 12 forming the rectangular tubular body has a width of 20 cm and a height of 15 cm. A through hole 13 having a diameter of 5 cm is provided in the center of the bottom plate 11. Two projecting plates 14 are attached to the upper and lower sides of the side plates 12 at the center of the outside so as to leave a gap of 3 cm. A round hole 15 is attached to each of the upper and lower projecting plates. As for the height of the protrusion plate 14, the width of the side plate is approximately 5 cm and the protrusion length thereof is 10 cm. The protrusion plate may be attached by welding the end portion of one straight plate to the side plate, or the protrusion plate bent in an L shape may be attached to the side plate by using a bolt nut.

The frame plate 2 is shown in FIG. A 1.6 mm-thick strip-shaped galvanized steel sheet is straight in the longitudinal direction by pre-notch roll forming and has a modified I-shaped cross section, and a flange 21 with a width of 25 mm is formed parallel to the top and bottom, and the gap between them is corrugated. It is connected by a web 22 bent into a mold. The height of the web is 15 cm. The web 22 is provided with two rows of oval connecting holes 23 parallel to the longitudinal direction at intervals of 5 cm.
The connecting holes 23 in the upper and lower two rows are the upper and lower projecting plates 1
It is provided at a position corresponding to the round hole 15 provided at 4. The length of the frame plate can be arbitrarily determined, but is usually 1 to 2 meters.

In the case of construction, as shown in FIG. 4, the connecting tools 1 are installed at equal intervals vertically with the bottom plate 11 as the slope side.
The frame plate 2 is bridged between the adjacent connecting tools 1, and both ends of the frame board are fixed to the upper and lower projecting plates 14 of the connecting tool 1 by using two sets of bolts and nuts. By repeating such an operation, the lattice-shaped method frame A is assembled on the slope. When the legal frame A is constructed, as shown in FIG. 1, the ground anchor 3 is driven into the slope through the through holes 13 of the bottom plate 11 of each connecting tool 1. The earth anchor consists of a rebar with a diameter of 3 cm and a length of 5 m. Leave a screw on the top. When driving, the upper end of the ground anchor 3 is made to project from the bottom plate 11, and the upper end of the connecting tool 1 is not projected.

A holding plate 4 having a hole of 3 cm in the center of a steel plate having a thickness of 5 mm is inserted into the upper end of the earth anchor 3, and a holding nut 41 is used to tighten the holding plate to strongly tighten the bottom plate 11. Press on the slope. The mortar 5 is filled in the space around the ground anchor 3 in the rectangular tubular body 10 of the connector 1. The mortar is finished flat according to the upper surface of the rectangular tubular body.

In the above embodiment, the planar shape of the connecting member is square, but this shape is not limited and may be circular as long as a plurality of projecting plates can be attached. In the embodiment, the ground frame was installed on the slope and then the ground anchors were mounted. However, it is possible to mount the ground anchors at a predetermined interval first and then install the frame. In the legal framework, we will usually cover the soil and then plant vegetation.

Second Embodiment Another example of the connector 1. Although it does not specify the manufacturing method, the manufacturing process will be described later to help understanding. As shown in FIG. 5, using a zinc-plated steel plate having a thickness of 3 mm, a rectangular side plate 12 having a height of 15 cm and a width of 10 cm, and projection plates 14 having a height of 5 cm and a width of 10 cm on both sides thereof. Are formed in a shape in which two pieces project vertically. One round hole 15 is provided in the central portion of the projecting plate, and a linear elongated fitting groove 16 parallel to the lower edge is provided at a position 3 cm from the lower edge of the side plate 12, one on each side. A shallow notch 17 is provided at each of the upper and lower portions of the base of the projection plate 14. As shown in FIG. 6, the steel plate formed in this way is bent 45 degrees toward the same side at the base of the projection plate 14 to form the assembly plate 18.

As shown in FIG. 7, a square bottom plate 11 having a side of a little less than 10 cm is formed by using a steel plate having a thickness of 5 mm. A through hole 13 having a diameter of 5 cm is provided in the center of the bottom plate, and two fitting protrusions 19 are provided on each of the four peripheral portions. The fitting protrusion is the fitting groove 16 of the above-mentioned assembly plate.
The size is such that

The connector 1 is assembled using four assembly plates 18 and one bottom plate 11. As shown in FIG. 8, the assembly plate 18 is overlapped with the projection plates 14, and the periphery of the base of the projection plate 14 is tied and temporarily connected by using an annealing wire. Tighten the notch 17 at the base of the protruding plate so that the smoothing wire does not move. In this manner, the four tubular plates 18 are temporarily connected to each other so that the projection plates 14 are radially projected to form the rectangular tubular body 10.
Make up. When the rectangular tubular body is assembled, the fitting projections 19 around the bottom plate 11 are inserted into the respective fitting grooves 16 to attach the bottom plate 11 to the rectangular tubular body 10. Projection plate 1 from the four corners
The connector 1 of the present invention in which 4 is projected is completed. The method of using this connector is the same as that in the first embodiment. When the frame plate is connected to the protrusion plate with the bolts and nuts, the frame plate may be fixed so as to be sandwiched between the two protrusion plates. When the frame plate and the projecting plate are tightened with bolts and nuts, the connection between the assembled plates becomes reliable at the same time. The annealing number line used for the temporary connection may be removed at this stage.

[0013]

[Effect] Since the present invention is constructed in this way, it has the following features. 1 Since the bottom plate is pressed against the slope by the pressing plate and the pressing nut, the connector itself is also pressed against the slope, and the frame plate connected to the connector also has an effect of suppressing the slope. 2 The upper end of the earth anchor fits inside the connector, and the retaining plate and retaining nut are also embedded in the mortar inside the connector, so they are protected from rust and do not protrude above the connector. As it is finished flat as a whole, it looks good. 3 The legal frame is connected to the ground anchor that is firmly driven in, so it has a very high stability, and therefore the soil in it and the greening of vegetation are also stable. 4 When the connecting tool is constructed as an assembly type as in the second embodiment, it is compact and convenient for storage and transportation.
