Description

The present invention relates to a fence. More specifically, the present invention relates to a fence suitable for installation at the boundary of sites, buildings, etc.

Traditionally, stacked block fences have been used for fences installed at the boundaries of sites and buildings. A stacked block wall is a wall constructed by stacking concrete blocks specified by JISA 5406 in several tiers (often 5 to 10 tiers), inserting reinforcing bars specified by JIS G 3112, fixing them with cement, and erecting them on a cloth foundation.
These stacked block walls are prone to collapse due to earthquakes if they are poorly constructed, and if they collapse, it can cause serious personal injury. In addition, there are inconveniences in construction, as it takes time and effort to pile up the piles manually on site, and it takes several days for curing.

The prior art disclosed in Patent Document 1 is a technique in which a lightweight fence is attached on top of a block wall. The block wall is made by stacking blocks specified in JISA5406 in several tiers, and the number of tiers is relatively small.The fence also serves as a decorative fence, and is placed over the top of the block wall from above and attached using the wall mounting section. be.
Although this conventional technology has a small number of stages, it is susceptible to collapse due to earthquakes, and if it collapses, it may cause serious personal injury.
In addition, there are inconveniences in construction, as it takes time and effort to pile up the piles manually on site, and it takes several days for curing.

The prior art disclosed in Patent Document 2 is a fence consisting of a basic block body and a fence body planted on the upper surface of the basic block body.
The basic block body is either a rectangular vertical plate with an I-shaped cross section, or a vertical plate with a bottom plate provided at the bottom and an L-shaped cross section. The basic block body of any shape is made of precast concrete.

The fence body is a decorative fence made of metal rods. Since the fence of this prior art is installed in the foundation block body, it cannot be replaced if it gets dirty or damaged. For this reason, there is a problem that the aesthetic appearance cannot be maintained after a certain period of use.

FIG. 5 is a partial perspective view of the fence section 2 of FIG. 4 viewed from the front side. FIG. 4 is a perspective view of a holding fitting 43;

Next, embodiments of the present invention will be described based on the drawings.
In FIG. 1, A is a fence, which is composed of a fence base part 1 and a fence part 2.
The fence foundation 1 is constructed by a required number of foundation blocks 3 arranged side by side, and is installed on a crushed stone foundation 6.
The plurality of foundation blocks 3, 3 are connected to each other with appropriate connecting fittings. When the foundation block 3 is installed, the part below the ground GL becomes the foundation part 3a, and the part above the ground GL becomes the decorative surface 3b.
The fence portion 2 is made up of pillars 4 and face members 5. An appropriate number of pillars 4 are erected on the upper surface of the wall foundation 1. The plurality of face materials 5 are supported by support columns 4, 4.
In the present invention, the fence base part 1 can have any configuration, and the structure of the fence part 2 is distinctive.

The face material 5 used for the fence portion 2 of this embodiment is a long plate material, as shown in FIGS. 1 and 2. The material, thickness, and width of the face material 5 can be selected arbitrarily. The length of the face material 5 may be adjusted to the distance between the supports 4, 4.

The structure of the support column 4 will be explained based on FIGS. 4 and 5.
The support column 4 consists of a column-shaped column body 41 and a holding fitting 43 combined with the column body 41.
A holding groove 42 into which the end of the face material 5 is fitted and held is formed on the side surface of the column 41. When placing the facing material 5 on one side of the column 4, it is sufficient to form a holding groove 42 on one side of the column 41. When placing the facing material 5 on both sides of the supporting column 4, holding grooves 42 may be formed on both sides of the column 41. A groove 42 may be formed.
This holding groove 42 is formed in an inclined manner on the side surface of the columnar body 41, and has an open upper end and a closed lower end. With this structure, the face material 5 can be dropped and fitted into the column 41.

The angle of inclination of the holding groove 42 is arbitrary, but is generally 55° to 90° with respect to the horizontal line. When the slope is within this range, the face material 5 can be used to hide the screen while also providing good ventilation.
The number of holding grooves 42 is matched to the number of face members 5 to be attached. In the illustrated example, there are seven, but the present invention also includes six or less and eight or more.

In the support column 4 shown in FIG. 1, the holding grooves 42 are formed on both sides of the column body 41. This is to support the face material 5 on both sides of the column 4 together with another column 4. Note that the support posts 4 used at the ends of the fence may be provided with holding grooves 42 only on one side, or may be provided with holding grooves 42 on both sides.

The holding fitting 43 is a fitting attached to the column 41 to prevent the face material 5 fitted into the holding groove 42 from coming off.
As shown in FIG. 6, the holding fitting 43 is made of an angle material having an L-shaped cross section, and a fitting groove 44 is formed on one side of the angle material.
The fitting groove 44 is open at the lower end and closed at the upper end. The fitting groove 44 is inclined, and the angle of inclination is the same as that of the holding groove 42 of the support column 4.
Several screw insertion holes 45 are provided on the other surface of the angle member, and the holding fitting 43 can be fixed to the column 41 of the support 4 by inserting screws through the screw insertion holes 45.

Next, a method of constructing the fence portion 2 will be explained with reference to FIGS. 4 and 5.
First, the support column 4 is erected on the foundation block 3. To erect the pillars 4, a method is generally used in which the base pipe of the pillar 4 is inserted into a hole formed in the foundation block 3 and solidified with cement, but the method is not limited to this method and any method can be used.

Then, the end of the face material 5 is inserted into the holding groove 42 of the upright pillar 4. FIG. 5 shows that three panels 5 on the lower tier side are inserted, and a fourth panel 5 from the lower tier is inserted. Although only one support 4 is shown in FIG. 5, another support is actually prepared so that both ends of the face material 5 can be supported.
If the facing material 5 is inserted through the opening at the upper end of the holding groove 42, it will stop at the closed lower end, so it can be held simply by inserting the facing material 5. Since the holding groove 42 is inclined, the facing material 5 can be held in an inclined state. It can be held with

When all the face materials 5 are inserted into the two pillars 4, 4, the holding fittings 43 are fitted so as to cover the tops of the face materials 5. In the column 4 shown in FIG. 4, the left side shows a state in which the holding fitting 43 is fixed to the column 41 without the face material 5 shown, and the right side shows a state in which the holding fitting 43 is fixed to the column 41 with the facing material 5 shown. It shows.

When constructed as described above, the face material 5 is restrained by the holding fittings 43 so as not to slip out, as shown in FIGS. 1 and 3. In other words, if the holding fittings 43 are attached with the face material 5 inserted into the holding groove 42 of the support column 4, the face material can be prevented from coming off, so that it can be used safely for a long period of time.

In the present invention, by using the holding grooves 42 on both sides of the support column 4, the panel material can be held on both sides of the column.If the support columns 4 are erected at intervals, the panel material 5 can be installed in a row. A long fence part 2 can be easily constructed.
In addition, when the facing material 5 is long, if a plurality of facing materials 5 are connected to each other with metal fittings, hanging of the facing material 5 can be prevented. The shape and structure of the metal fittings used for this purpose are arbitrary and are not limited in any way.

In the fence part 2 according to this embodiment, when the facing material 5 becomes dirty or damaged, it can be easily replaced by simply removing the facing material 5 from the holding groove 42 of the support post 4 and inserting a new facing material 5. For this reason, it becomes possible to maintain a beautiful appearance for a long period of time.

The details of the fence foundation 1 will also be explained.
As shown in FIGS. 1 and 3, the foundation block 3 consists of a standing wall 10 and a bottom slab portion 20. The vertical wall 10 is a member that rises upward with a predetermined thickness, and is divided into a decorative surface 3b and a base portion 3a as described above.
The bottom plate portion 20 is a member formed to protrude from the lower end of the standing wall 10 to the back side, and is also called a footing.

On the upper surface of the bottom plate section 20, mounting sections 21 for mounting weight blocks 30, which will be described later, are formed at intervals in the lateral direction. Further, a regulating wall 22 stands up between the individual placing portions 21 .
The regulating wall 22 has a trapezoidal cross section and extends in the depth direction on the bottom plate portion 20. The interval between adjacent regulating walls 22, 22 is set to be slightly wider than the width of the weight block 30.

The weight block 30 is a block for adding weight to the base block 3. The shape and dimensions may be matched to the mounting portion 21 of the foundation block 3. Alternatively, the weight block 30 may have an arbitrary shape and weight, and the shape and dimensions of the mounting portion 21 of the foundation block 3 may be matched to the weight block 30. The point is that the base block 3 and the weight block 30 are separate members, and their shapes are not limited to those shown.

As shown in FIG. 2, the weight block 30 is a concrete member that has an inverted L shape when viewed from the side, a square when viewed from above, and a square when seen from the back.
As shown in FIG. 3, when the weight block 30 is placed on the mounting portion 21, it fits between the regulating walls 22, 22 on both sides and is immovably restrained in the left-right direction, as shown in FIG.
When restrained in the left-right direction in this manner, the weight block 30 becomes difficult to come out in the rear direction as well.

As shown in FIGS. 1 and 3, a vertically oriented first bolt hole 31 is formed in the weight block 30, and a vertically oriented second bolt hole 23 is also formed in the mounting part 21 of the foundation block 3. . These two bolt holes 31 and 23 are formed to be coaxial when the weight block 30 is placed on the mounting portion 21. The combination of the first and second bolt holes 31 and 23 corresponds to the bolt hole referred to in the claims.
As shown in FIG. 3, by passing the anchor bolts 32 through the first bolt holes 31 and the second bolt holes 23 and solidifying them with cement, the weight block 30 can be firmly fixed on the foundation block 3.

Since the foundation block 3 is separate from the weight block, the foundation block 3 and weight block 30 can be kept small and lightweight even if the entire fence is increased in size. Therefore, construction can be carried out in narrow spaces using small heavy machinery.
