[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a safety fence installed on, for example, a boardwalk or a plaza.

[0002]

[Problems to be Solved by the Prior Art and Invention] Generally, a pedestrian is guided to a promenade, a plaza, etc.
Alternatively, a safety fence is often provided for the purpose of restricting traffic for safety.

Conventionally, this kind of safety fence has been used only for the purpose of pursuing only the functional side, and an iron pipe or an SL-shaped steel surface is simply plated or baked for the purpose of preventing rust.

Further, since a screw member is used for joining the parts to each other, it is necessary to screw the parts one by one. Therefore, a considerable number of screws are required, and the management and tightening work thereof is required. It was extremely annoying.

Further, a product simply plated or painted is not always suitable for a place such as a park or a townscape where the landscape is important.

The present invention has been made to solve the above problems, and an object thereof is to provide a safety fence which is easy to assemble and excellent in decorativeness.

[0007]

According to a first aspect of the present invention, a safety fence according to claim 1 is provided with a plurality of struts installed at predetermined intervals and a plurality of struts suspended between the struts in a plurality of steps. In a safety fence comprising a book furring strip, the pillars and furring strips are formed by projecting zinc-iron alloy grains on the surface of a steel material, and zinc chromate-treated or phosphate-treated- The adhesive base treatment is performed by applying an iron alloy coating, and the adhesive base treatment is covered with a decorative member, and the tenons are formed on both ends of the furring strip at the ends of the furring strip. The plurality of mortises formed on the side surface of the stanchion, and one connecting pin is continuously inserted into the pin holes formed on the mortise to form the plurality of mortises on the side surface of the support column. It is configured by connecting the furring edges of .

A safety fence according to a second aspect of the present invention is provided with a plurality of support columns built at predetermined intervals and a plurality of furring strips bridged between the support columns. In a safety fence, the support post and the furring strip are formed by projecting zinc-iron alloy particles on the surface of a steel material, and an adhesive substrate treatment is performed by applying a zinc-iron alloy coating that has been chromate-treated or phosphate-treated. And covering the surface of the adhesive substrate with a decorative member, and the furring strip has a side surface of the strut at a notch formed so that the steel material is exposed at the end of the furring strip. A bracket projecting from the section is fitted and the bracket is screwed to the steel material to connect the plurality of furring strips to the side surface of the column.

Here, the steel material is bar steel, flat steel, shaped steel, steel pipe, or the like, and the material is steel, surface-treated steel such as aluminum or galvanized steel, or alloy steel such as stainless steel. For the purpose of improving the adhesion durability between the steel material and the decorative member, a zinc-iron alloy formed by projecting zinc-iron alloy particles on the surface of the steel material as an adhesion undercoat treatment and subjected to chromate treatment or phosphate treatment. A coating may be applied (see Japanese Patent Application No. 62-81900).

At both ends of the furring strip 3, tenons 9 which can be inserted into the tenon holes 8 are formed in a substantially rectangular cross section, and the tenons 9 are provided.
A pin hole 10 for inserting the connecting pin 4 is vertically formed therethrough.

The tenons 9 at both ends of the furring strip 3 are inserted into the tenon holes 8 of the support column 1, and one connecting pin 4 is continuously inserted into the pin holes 10 of each tenon 9. In this case, all the pin holes 10 of each tenon 9 are oriented right above so that the connecting pin 4 can be continuously inserted from right above at a stretch. With such a configuration, both ends of each furring strip 3 are connected to the column 1.

Example 2. FIG. 3 shows an embodiment of the safety fence according to the second aspect of the present invention. In the figure, the same parts as those of the first embodiment and corresponding parts are designated by the same reference numerals, and the description thereof will be omitted. Reference numeral 11 is a bracket projecting from the side surface of the strut 1 for connecting both ends of the furring strip 3 to the side surface of the strut 1, and 12 is a bracket 11 fitted into the end of the furring strip 3 for Is a cutout portion formed by cutting out a part of the decorative plate 7 in order to screw it to the rectangular steel pipe 6.

The bracket 11 is provided with a notch 12 at the end of the furring strip 3 to form an L-shaped side surface from a horizontal portion 11a and a vertical portion 11b which are respectively provided along the lower surface and the side surface of the exposed rectangular steel pipe 6. Is formed in. And the bracket 11
The horizontal part 11a of the rod and the end of the square steel pipe 6 with a plurality of connecting screws.
The end portion of the furring strip 3 is connected to the side surface portion of the column 1 by screwing with 13. The other structure is almost the same as that of the first embodiment.

Embodiment 3. FIG. 4 also shows an embodiment of the safety fence according to claim 2 of the present invention. In the figure, the same parts as those of the first and second embodiments and the corresponding parts are designated by the same reference numerals, and their description will be given. Is omitted. Reference numeral 14 is a wooden furring that is bridged between the columns 1 and 1, and both ends of the furring 14 are horizontal portions 11 of the bracket 11.
A plurality of wood screws 15 are screwed into the furring strip 14 from the back side of a to be connected to the side surface of the column 1. Other configurations are almost the same as those of the first and second embodiments.

EFFECTS OF THE INVENTION The safety fence according to the first and second aspects of the present invention has the above-described structure, and the pillars and the furring strips are formed by coating the surface of the steel material with a decorative member. Therefore, by using a decorative member suitable for the surrounding environment, it is possible to obtain a highly safe safety fence that matches the surrounding environment.

Further, since the surface of the steel material is formed by projecting zinc-iron alloy particles, and is subjected to an adhesive undercoat treatment with a zinc-iron alloy coating film which has been subjected to chromate treatment or phosphate treatment, Adhesiveness of the decorative member is very good, and it has excellent durability.

Particularly, in the safety fence according to the first aspect of the present invention, the tenon having both ends of the furring strip formed at the ends of the furring strip is inserted into the tenon formed in the side part of the support column, and the tenon is provided in the tenon. By continuously inserting one connecting pin into the formed pin hole, the ends of the plurality of furring strips are connected to the side surface of the strut, so that the plurality of furring strips are connected to the strut. It is possible to very easily and surely connect to the side surface portion, and it is possible to reduce the number of connecting pins, which makes it easier to manage parts.

Further, in the safety fence according to the second aspect of the present invention, the bracket and the screw member for screwing the bracket to the steel material of the furring strip are housed in the notches and are not exposed to the outside. Since there is no step or seam at the connecting part with the members connected to each other, not only the appearance is good, but also the danger that a passerby hits the bracket or the screw member with a hand etc. and is injured, etc. Has the effect of. Furthermore, since the bracket and the screw member are not exposed to rainwater, there is an effect that rusting of these members can be prevented.
