2. Description of the Related Art Conventionally, a block fence uses a concrete block having a hollow portion for the purpose of weight reduction of concrete and insertion of a reinforcing bar, and mortar is packed between the concrete block and a foundation concrete and between concrete blocks. Since the work was piled up, it took time to complete the work, and it was also necessary to finish the surface with mortar and to install decorative materials such as tiles to improve the aesthetics. There is a problem that it is difficult to replace the damaged cosmetic material and change the design of the cosmetic material while the construction is performed for a long time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the gist of the invention is to stack rectangular plastic frames by fastening them vertically and laterally via a connector.
In a plastic fence having a decorative plate attached to at least one side of the frame, the lowermost plastic frame is fastened directly to anchor bolts embedded in the foundation concrete or via a lip grooved steel. The plastic frames adjacent to each other are fixed at the corners where they intersect by a cross-shaped inner connecting tool and outer connecting tool, or erected on a foundation concrete at predetermined span intervals. And a plastic fence fixed by fastening to the external connecting tool.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. 1 is a perspective view partially showing a plastic frame used in the present invention, FIG. 2 is a perspective view showing an inner connecting tool used in the present invention, and FIG. 3 is a perspective view showing an outer connecting tool used in the present invention. FIG. 4 is a sectional view showing a state in which a plastic frame is fastened on the base concrete, FIG. 5 is a partially cutaway perspective view showing a state in which a boom is mounted on the base concrete, and FIG. 6 is an assembled view of the present invention. The state is shown in a partially omitted notched front view.

In the present invention, a plastic frame 1 shown in a partially omitted perspective view in FIG. 1 is fixed on a foundation concrete as shown in a sectional view in FIG. The plastic frame 1 is sandwiched between an inner connector 3 shown in a perspective view in FIG. 2 and an outer connector 4 shown in a perspective view in FIG. Alternatively, as shown in a partially cutaway perspective view in FIG.
The plastic frames 1 are fastened and fixed between them.

The plastic frame 1 used in the present invention is manufactured by assembling a general-purpose plastic such as polyethylene, polypropylene, polyvinyl chloride or the like by injection molding or press-molding a member by secondary processing such as butt welding. As shown in FIG.
On the four sides of the front and rear surfaces, a decorative plate mounting groove 13 is formed outwardly around a connecting groove 12 having a width d, and only four corners are cut by notches 131.

If the plastic frame 1 is rectangular, a reinforcing member 111 is appropriately formed in the longitudinal direction.

In order to fix the plastic frame 1 on the foundation concrete A, as shown in FIG. 4, the lip grooved steel 6 is fastened by anchor bolts 9 buried at predetermined intervals in the foundation concrete A in the installation direction of the fence. Then, the bolt hole 121 of the connection groove 12 of the plastic frame 1 is formed.
The plastic frame 1 can be fixed to the lip grooved steel 6 by arranging washers 7, 7 on the side of the connection groove 12 and inside thereof and passing the bolt 8 through the bolt 8.

The connecting members for fixing the plastic frame members 1 to each other include a cross-shaped inner connecting member 3 shown in FIG. 2 and a cross-shaped outer connecting member 4 shown in FIG. Screw holes 32 are formed on both sides, and an inner connecting arm 31 projects vertically and horizontally around the screw hole 32. The inner connecting arm 31 projects four plastic frame bodies 1 from each other. Adjacent frame 1 having width d formed at the corner when fitted
It has such a size that it can be inserted between the connecting grooves 12 to 12 without leaving a gap.

The outer connecting member 4 has a screw hole 4 at the center.
2 and the outer connector arm 41 around the screw hole 42.
The outer connecting arm 41 is bent at one side into a C-channel shape, and the plastic frame 1
Have a size that can be straddled between the decorative plate mounting grooves 13, 13 of the adjacent frame bodies 1, 1 when four of them are abutted.

The inner connector 3 and the outer connector 4 are attached in the vertical direction b where four plastic frames 1 intersect, as shown in a partially cutaway front view in FIG. 3 is inserted into the connecting groove 12 where each plastic frame 1 intersects, and the outer connecting arm 41 of the outer connecting tool 4 intersects the plastic frame 1 from the front and rear sides thereof. The four plastic frames 1 can be fixed to each other by being inserted into the decorative plate mounting groove 13 and fastened by screwing the screws 5 from the front and rear screw holes 42 to the screw holes 32.

Although not shown, if necessary, the inner connector 3 and the outer connector 4 are T-shaped, that is, the connector arms 31,
By using a T-shaped joint that protrudes three sides of the plastic frame 41, the side ends and the upper end of the stacked plastic frames 1 can be fixed to each other.

Further, as described above, the inner connector 3 and the outer connector 4
In addition to the case of fixing the spaces between the plastic frames 1 in the vertical direction of b, as shown in FIG. 5, the lower end is fixed to the lip grooved steel 6 fixed on the foundation concrete A by the anchor bolt 9 and the fixing bolt 8 The ridges 2 fastened by the above are erected at predetermined span intervals, and as shown in FIG. 6, the plastic frame 1 Notch 131 formed in 1
The outer connecting member 4 is applied to the front side and the rear surface side, and the screw 5 is passed from the screw hole 42 of the outer connecting member 4 to the outer connecting member fastening hole 21 of the cubic 2 to be fastened. 1 can be fixed between each other.

As described above, the plastic frame 1 is fixed on the foundation concrete A, and the space between the plastic frame 1 in the vertical and horizontal directions is sequentially changed by using the inner connecting tool 3 and the outer connecting tool 4 or the outer frame 2 After attaching and fixing a predetermined fence frame using the connecting tool 4, the decorative plate mounting groove 1 of the plastic frame 1 is mounted.
Decorative plate 1 with locking pieces that are fastened to 3 at one touch
Attach 0 to complete the construction of the fence.

After the construction as described above, joints between the decorative plates 10 (adjacent plastic frame 1
Joints may be inserted between the decorative plate mounting grooves 13 of the fence, and a pillar is erected at the side end of the fence, or a fence is laid laterally over the entire upper end of the fence to reinforce the entire fence. You can also.

Since the present invention has the above-described structure, the following effects can be obtained. That is, according to the present invention, since a lightweight frame made of plastic is used, it is extremely lightweight and easy to handle as compared with a conventional concrete block, and even when the frame is fixed on the foundation concrete, the stacked connection between the frames can be performed. Since it can be easily fastened with bolts and screws, it is less time-consuming than the conventional method of mortar filling between concrete blocks and the construction work period can be shortened, and when the design of the decorative board is changed or the decorative board is damaged It has effects such as easy replacement and repair.
