However, in such a conventional fence, it is difficult to match the bolt hole of the face material with the bolt hole of the strut in the previous construction example, and in the latter construction example, it is more difficult than the upper end of the strut. There is a problem in that it takes a lot of time to carry out the work while vertically supporting the face material by lifting it up from above, and it is difficult to align the upper end of the groove of the support with the other end of the face material. In addition, these conventional fences have a drawback in that, for example, when performing maintenance such as cleaning of a surface material, it takes a lot of time and labor such as forming a scaffold outside the retaining wall.

The present invention has been made in view of such conventional problems. First, the construction is simple and the inspection,
It is an object of the present invention to provide a fence and a method of constructing a fence that have good workability and can easily perform maintenance such as repair and cleaning.

[0006]

In order to solve the above problems, the present invention has the following configuration. That is,
Fence with good workability according to the present invention is a fence that is installed on the retaining wall such as an edge of a bridge or embankment or a lane divider, and the columns are erected on the retaining wall and the surface between the columns is The material is supported, and the surface material can be tilted by itself, or the surface material can be tilted inside the retaining wall together with the pillar.

According to the present invention, the pillar and the face member can be assembled inside the retaining wall, that is, only on one side of the retaining wall, the workability is good, and it is not necessary to work from the outside of the retaining wall, which is safe. At the same time, check the surface material even after the installation of Fence,
For maintenance such as repair, cleaning and replacement when damaged, it can be easily done by tilting the fence inside the retaining wall. In the present invention, the face material can be tilted by itself, or the face material can be tilted to the inside of the retaining wall together with the support, and may be tiltable only to the inside of the retaining wall, or only to the inside of the retaining wall. Alternatively, it may be tiltable to the outside.

In the present invention, a support shaft is provided so as to project horizontally in the lower part of the support column, and a face material support member is formed in the rear of the support shaft along the height direction of the support column. A fixing means such as a bolt hole or a projecting bolt is provided in the upper portion, a bearing having inverted U-shaped grooves is formed in the lower left and right of the face member, and a bolt hole is formed above the face member. The bearings at the bottom of the face plate are fitted to the support shafts at the bottom of the column so that the face plate can be tilted inside the retaining wall.The face plate raised from the tilted state becomes the face plate support member at the rear of the column. It may be arranged so that it is bolted along the fixing means of the face material support member and the bolt hole portion of the face material.

In this way, the face material can be attached to the column from the inside of the retaining wall only by fitting the bearing of the lower face material to the support shaft of the column lower part, and the face material can be fixed to the column. Also, when doing so, simply raising the face material from the tilted state and aligning it with the face material support material at the rear of the column makes it easier to secure the fixing means such as bolt holes or protruding bolts of the face material support material and the bolt hole of the face material They can be matched, and the surface material can be firmly fixed to the pillar from the inside of the retaining wall only by a simple bolting work, and the workability of construction is good and it can be performed safely.

Further, in the present invention, a supporting column support member is attached to the retaining wall, the lower part of the supporting column is pivotally attached to the supporting column support member so that the supporting column can be tilted inside the retaining wall, and is raised from the tilted state. Further, the lower part of the column of the column and the column receiving member may be fixed with a bolt, and the face member may be attached to the column.

With this configuration, the pillar and the face member can be assembled inside the retaining wall, and the workability is improved without the need to install a foundation or the like outside the retaining wall. It is safe because there is no need to work from the outside of the retaining wall. Further, basically, it is a member with a small number of points such as a pillar support material, a pillar and a face material, and it becomes possible to construct a fence easily and safely.

Further, in the present invention, the supporting column receiving member is attached to the retaining wall, and the supporting column lower portion is pivotally attached to the supporting column supporting member so that the supporting column can be tilted inside the retaining wall and the height of the supporting column can be increased. The face material groove may be formed along the direction, and the face material may be inserted into the face material groove in a state where the support pillar is tilted inside the retaining wall, and the support pillar may be raised together with the face material. .

With this configuration, the face material can be attached to the support column while the support column is tilted inside the retaining wall, and it is unstable and unsafe that the face material is lifted up to work as in the conventional case. After installing the face material without performing work, you can construct by simply raising the support together with the face material from the inside of the retaining wall and fixing the lower part of the support and the support receiving material with bolts. Since the face material can be attached to the column by simply inserting both end portions of the face material into the groove, the work of attaching the face material can be quick and easy.

Further, in the present invention, the column and the face material support frame are attached to the retaining wall, the periphery of the face material is held by the face material frame, and the lower frame of the face material frame is the face material support frame. The face material may be detachably attached to the support wall so that the face material can be tilted inward of the retaining wall, and the face material frame of the face material raised from the tilted state is fixed to the column.

In this way, in addition to the above effects,
The face material frame can protect the face material from damage or the like. This is effective when the face material is made of a synthetic resin plate such as polycarbonate or acrylic resin, which is relatively easily damaged, or tempered glass.

Further, according to the present invention, the arm is pivotally attached to the support column standing on the retaining wall so as to be tiltable inside the retaining wall, and the pair of adjacent arms is tilted in the tilted state. A face member held by a face member frame may be rotatably mounted between the tip portions, and the arm raised from the tilted state together with the face member may be fixed to the column.

By doing so, the installation work is completed simply by raising the face material together with the arm and fixing it to the column, so that the fence can be installed extremely quickly and the time required for traffic regulation etc. is shortened. However, there is less risk of hindering smooth traffic.

Another fence with good workability according to the present invention is a fence to be installed on a retaining wall such as an edge of a bridge or an embankment or a lane divider, and a pillar is erected on the retaining wall. At the same time, a face material whose periphery is held by a face material frame is supported between the columns, and one side of the vertical side is detachably supported by a column facing one of the vertical sides, so that the inside of the retaining wall is supported. It is characterized in that the other vertical side of the face member that can be opened and closed in the horizontal direction and that is closed from the open state is fixed to a column facing the vertical side.

According to the present invention, assembling and maintenance of the support column and the face material can be performed inside the retaining wall, the workability is good and safe, and the horizontal direction can be opened and closed. Even in the case of a large size, the face material can be easily opened and closed during the installation of the fence and during the maintenance after the installation.

The fens according to the present invention may be formed by arranging a plurality of fenth bodies in the up-down direction, in the longitudinal direction or in parallel. In this case, at least one of the fenence bodies has the above-mentioned effect. It is preferable that the fence has good workability as described above.

Next, the method for constructing the fence according to the present invention is as follows.
