Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a fixture for fixing a frame unit to be laid on a slope in the slope vegetation method.

[Prior art]

The present applicant previously filed an application as Utility Model Application Publication No. 81639/1983 regarding a fixing metal fitting for a frame unit to be laid on a slope in this type of slope vegetation construction method.

As shown in FIG. 4, this fixing fitting V invented in the previous application is used at the intersection of orthogonal members X and Y laid on a slope. As shown in FIG. 5, the fixing fitting of this prior application has a notch, an outer protrusion on the outside, an inner protrusion on the inside, an L-shaped cut groove L formed between the inner and outer protrusions, and an upright tongue piece. Using flat plate materials A and B with cut grooves separating them, the notches of the pair of flat plate materials A and B are made to face each other so that they intersect each other at right angles, and then L-shaped cuts are made in the flat plate materials A and B. Fit the right-angled bent part of the groove L into the right-angled bent part of the other party, and make the inner and outer protruding parts protrude to the outside of the orthogonal intersecting parts of the materials A and B, and at the same time, attach the upright tongue to the inner and outer protruding parts. They are constructed by standing up in parallel.

As shown in FIG. 4, this fixing metal fitting V has orthogonal members X and Y inserted between the upright tongue piece that stands up on the outside and the inner and outer protrusions (indicated by t and t), respectively. Orthogonal members X, Y perpendicular to the inside
It is intended to be applied.

And the idea of this earlier application is the material A to be combined,
Although this method was successful in connecting B easily and firmly, the following problems were subsequently discovered.

That is, due to the narrow width of the right-angled bent portion of the L-shaped cut groove l between the inner and outer protrusions of materials A and B, and the complicated structure of the right-angled bends, materials A and B
It is extremely difficult to combine the two.

[Means for solving problems and their effects]

In the present invention, in order to solve the problems of the earlier invention, the materials A and B of the frame unit to be laid on the slope are constructed as follows.

That is, while the upright tongue pieces 1a, 1b are cut in the lower part, the notches 5a, 5b and the central protruding parts 3a, 3 are cut in the upper part.
b, spacing parts 6a, 6b, one side protrusions 4a, 4b are arranged, and notches 5a, 5 of central protrusions 3a, 3b are provided.
Materials A and B are constructed by cutting central grooves 8a and 8b on the b side and cutting grooves 7a and 7b on the interval portions 6a and 6b of the protrusions 4a and 4b on one side. Either one of A and B is turned over so that they face each other, and the upright tongue pieces 1a and 1b are erected at right angles to the materials A and B on the front side of the opposing part, and the central protrusion 3b of one material B is placed on the other side. Material A
After inserting the protrusion 4b on one side of one material B into the notch 5a of the other material A into the gap 6a, cut grooves 7a and 7b on one side of materials A and B, and center cut groove 8a of the materials A and B. , 8b are bonded together by sliding one material B against the other material A in the direction in which the materials A and B are engaged with each other.

By adopting such a configuration, the present invention has one side protruding portion 4 compared to the frame material unit of the earlier application.
a, 4b, and the spacing section 6 between the central protrusions 3a, 3b.
a, 6b, notch portions 5a, 5b can be widened, and one side notch grooves 7a, 7b, center notch groove 8
Since the cutting depths of a and 8b can be made small, the fitting work when combining materials A and B can be easily performed as a whole.

[Explanation of Examples]

Examples of the present invention will be described below.

First, each member in the drawings will be explained.

A, B: Materials constituting the frame material unit of the present invention, 1a, 1b: Crease line 2 at the bottom center of materials A, B
The erect tongue piece is bent and erected at a and 2b.

2a, 2b: Crease lines of the upright tongue pieces 1a, 1b, 3a, 3b: One side protrusion between the upper parts of the materials A, B, with a gap 6 between them and the one side protrusion 4a, 4b.
Leave a and 6b open.

Further, the one side protrusions 4a, 4b are spaced apart from each other by the space 6.
One-side cut grooves 7a and 7b are cut into the base portions of sides a and 6b.

4a, 4b: One side protrusion provided close to one side of materials A, B and shifted by the width of narrow notches 9a, 9b; 5a, 5b: One side protrusion 4a, 4b of central protrusion 3a, 3b. Notches on the opposite side, 6a, 6b: Space between protrusions 4a, 4b on one side, center protrusions 3a, 3b, 7a, 7b: Space 6 between protrusions 4a, 4b on one side.
Cut grooves provided at the bases of a and 6b; 8a and 8b: cutout portions 5 of central protrusions 3a and 3b;
Cut grooves provided on sides a and 5b, 9a and 9b: Additional notches with a small width provided on the opposite side of central protrusions 3a and 3b of protrusions 4a and 4b on one side; however, this additional notch is provided for the sake of balance in form and is not necessarily necessary.

The method for joining materials A and B will be explained below.

First, as shown in FIG. 2, one of the materials B is turned over, and the protrusions 4a and 4b on one side thereof are positioned opposite to each other to face each other.

When FIG. 2 is developed in a plan view, the protrusions 4a and 4b on one side are adjacent to each other as shown in FIG. 1.

That is, if either of the materials A and B is turned over, they will have exactly the same shape.

After raising the upright tongue pieces 1a and 1b upward as shown in FIG.
into the space 6a.

Next, the one side protrusion 4b and the center protrusion 3a of the material B are cut into the center cut grooves 8a, 8b, the one side cut groove 7a,
If the parts 7b are slid so as to mesh with each other, the two parts are joined as shown in FIG.

The fixing metal fitting of the present invention constructed in this manner has the upright tongue piece 1a, the central protrusion 3b, the one side protrusion 4b, the upright tongue piece 1a, the central protrusion 3a, and the one side protrusion. 4a are inserted into the orthogonal members X and Y, respectively, and the orthogonal members X and Y are abutted on the inside thereof.

[Effect of idea]

In the present invention, the widths of the one side protrusions 4a, 4b, the spacing parts 6a, 6b between the center protrusions 3a, 3b, and the notches 5a, 5b are wider than the frame material unit of the earlier invention. Since the cutting depths of the side cutting grooves 7a, 7b and the central cutting grooves 8a, 8b can be made small, the fitting work when combining the materials A and B as a whole can be easily performed.
