Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a concrete fence that is robust and can be easily constructed.

《Prior art》 Conventional concrete walls consist of a foundation and a wall made up of formwork, in which concrete is poured and hardened, and in recent years, the foundation is made of formwork and concrete blocks are stacked on top of the foundation. However, many of them are constructed by bonding each type of concrete, and in order to strengthen the integrity of the concrete blocks and the foundation, reinforcing bars embedded in the foundation and erected are inserted through the concrete blocks.

[Problems that the invention aims to solve] The conventional concrete walls mentioned above require a foundation, and the formation of the foundation is done by assembling wooden forms on-site and filling them with concrete, which is time-consuming.
In addition to the need to procure frame materials, the work period will be long because the work will have to be stopped while the concrete is solidifying.

Furthermore, since the foundation and the wall board have different structures, there is a problem with their integrity, and there is a risk that the wall board portion may collapse due to earthquakes, wind, etc.

Furthermore, the framework of the formwork for forming the foundation requires intrusion into neighboring land and access for work, causing unnecessary trouble.

Even when concrete blocks are stacked, there are disadvantages in terms of working techniques and long working hours.

Therefore, the present invention attempts to solve the above-mentioned problems by forming the members constituting the fence in advance and easily assembling them on site.

<Means for solving the problem> The present invention involves inserting the lower part 9 of the fence plate 8 into the recess 3 provided in the rear wall 2 of the box-shaped foundation 1, and inserting the lower part 9 of the fence plate 8 into the
This is a concrete wall having a structure in which a wall plate 8 is clamped by a wedge 11 fitted into a wedge groove 5 provided in a side wall 4 of a foundation 1, and a wall plate 8 is erected and fixed.

《Function》 The present invention consists of a box-shaped foundation 1, a fence board 8, and a wedge 1.
It consists of three parts (1), each of which is molded in concrete at a factory etc. and then transported to the site and assembled.The assembly is done by installing the foundation 1 underground with the rear wall 2 aligned with the installation line of the fence, and then installing the foundation 1 underground. The lower part 9 of the fence plate 8 is inserted into the recess 3 provided in the wall 2, and the wedge 11 is inserted into the wedge groove 5 provided in the side wall 4 of the foundation 1, pressing against the front surface 8a of the fence plate 8, and the foundation is placed. The fence plate 8 is clamped and fixed between the rear wall 2 of the stand 1.

Then, by filling the box-shaped foundation 1 with earth and stones and burying it underground, the foundation 1 becomes integrated with the ground and stably supports the fence board 8.

Therefore, the foundations 1 are arranged horizontally in a row, the fence plates 8 are erected, and the adjacent foundations 1 and each fence plate 8 are connected by appropriate means to form a concrete wall.

"Example" Next, embodiments will be described based on the drawings.

FIG. 1 is a perspective view of an assembled concrete wall according to the present invention, which is composed of three members: a foundation 1, a wall plate 8, and a wedge 11, each of which is made of concrete.

FIG. 5 is a perspective view of the foundation 1, showing an example in which four box-shaped foundations 1 are integrally formed.
It can be formed singly or in a plurality of pieces as appropriate.

In the drawings, the foundation 1 has a box-like shape with the front wall removed, and has a recess 3 on the inner surface of the rear wall 2 for inserting a fence board, and a wedge groove 5 for inserting a wedge on the rear inner surface of the side wall 4.

The recess 3 has a tapered side surface 3a to facilitate insertion of the lower part 9 of the fence plate 8.

Further, the front surface 5a of the wedge groove 5 is inclined toward the rear surface 5b.

Reference numeral 6 denotes protrusions protruding inward at the top and bottom of the inner front part of the non-wedge groove 5 of the side wall 4 of the foundation 1, which strengthens the integrity with the ground when the foundation 1 is filled with soil and stones. 7 is a joint groove with the adjacent foundation 1.

FIG. 2 is a perspective view of the fence plate 8, and the lower part 9 is tapered on both sides so that it fits into the recess 3 of the foundation 1 and can be easily inserted. 10 is a joint groove with an adjacent wall plate 8.

FIG. 3 is a perspective view of the wedge 11, which is a flat bent plate, and the lower front surfaces 12a of both side pieces 12 are inclined to abut the front surface 5a of the wedge groove 5, making it easy to fit into the wedge groove 5. At the same time, the connecting piece 13
is pressed against the front surface 8a of the fence board 8.

FIG. 4 shows another embodiment of the wedge 11, in which side pieces 12 separated apart from the connecting piece 13 are respectively fitted into the wedge groove 5 to fix the fence plate 8.

《Effects of the invention》 As mentioned above, the present invention is extremely easy to construct because all the members that make up the fence are assembled on-site, and the time for foundation formation can be omitted, resulting in a short construction period. Because the foundation frame is formed, encroachment and occupation of neighboring land can be avoided.

Since the foundation 1 is box-shaped, it is stable, and by inserting the wedge 11, the weight of the wedge 11 is added, increasing stability. By integrating these, it has sufficient installation force to support and hold the fence board 8.

Furthermore, the fence plate 8 is fixed to the foundation 1 by fitting it into the recess 3 and clamping it with the wedge 11 fitted into the wedge groove 5, which makes the construction easy and the lower part of the fence plate 8. 9 is clamped and fixed, there is no problem with the bearing force, and the bonding force between the foundation 1 and the fence plate 8 is strong, so there is no fear that the fence plate 8 will fall due to earthquakes, wind, etc.
Furthermore, since the fence board 8 is a single board, there is no fear of partial collapse.

Since the fence board 8 is a single board, it has the advantage of being easy to manufacture a designed fence by applying various types of processing to the surface.
