Abstract

PURPOSE: To manufacture a guardfence of low cost which can prevent falling of a passenger or an article and damage due to strong wind and has strange elegance by mounting a grating panel of which the panel thickness and vertical/ horizontal diameter of the hole part are nearly same, on the gap part of a bridge. CONSTITUTION: A grating panel 3 made of metal, plastics, or wood of which the panel thickness and vertical/horizontal diameter of the panel hole part are nearly same, is mounted on the gap part 2 of horizontal beams of a guardrail for a road bridge or the like. By forming such guardrail, falling of a passenger or an article is prevented, air transmission in the perpendicular direction to the grating panel 3 becomes possible while preventing air transmission obliquely in all directions, up and down, right and left, and hence wind pressure at a strong wind is releaved through the opening parts so as to prevent damage. In addition by fitting a plurality of colorful marking members in the hole parts of the grating panel 3 and expressing letters, symbols, or designs, the appearance can be changed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective fence using a lattice panel, which is used for road bridges and the like.

[0002]

2. Description of the Related Art Conventionally, in a protective fence, a vertical lattice frame in which strips are vertically arranged is fitted between horizontal beams in order to prevent a passerby from falling and an article from falling.

In recent years, it has been known to attach a design panel made of cast aluminum, etc., because the landscape is emphasized.

However, although the vertical grating has a function of preventing transmission from the left and right diagonal directions, it cannot prevent transmission from the upper and lower diagonal directions.

An opaque plate is attached when it is desired not to allow the light to pass therethrough, but in some cases, it is damaged by strong wind because it is directly exposed to the wind.

Also, since it is an opaque plate, it also blocks transmission from the direct direction, giving a feeling of pressure, and in the morning and evening the sun's rays are blocked, the sidewalk becomes dark, and dust and the like tend to accumulate, making it airy. It had a drawback that the road surface was difficult to dry after rain and it became unsanitary.

[0007] Further, when the landscape is emphasized, a design panel made of aluminum casting or the like is used, but the design often deals with the tourism resources and special products of the land, so that one product becomes uniform and mass production is carried out. Has the disadvantage of being unsuitable and expensive.

[0008]

SUMMARY OF THE INVENTION Therefore, the present invention
It was invented to eliminate the above-mentioned drawbacks,
Not only does it prevent pedestrians and objects from falling through the gaps between the horizontal beams, but it also prevents penetration from all directions diagonally from top, bottom, left, and right. Is provided.

[0009]

In order to achieve the above object, the present invention provides a protective fence in which the thickness of the panel and the vertical or horizontal diameter of the hole of the panel are substantially the same in the clearance of the fence. It is a protective fence using a lattice panel, which is characterized by installing the lattice panel, and a plurality of colorful sign members are inserted into the holes of the lattice panel to express characters, symbols and designs. It is a protective fence using the lattice panel according to claim 1 characterized in that it is a thing.

[0010]

In the use of the present invention, by installing the lattice panel in the gap of the fence, and by fitting the marking member in the hole of the panel, characters and symbols are formed on the lattice panel. is there.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An optimum embodiment of the present invention will be described below with reference to the accompanying drawings. In a protective fence (1), a thickness dimension (X) of a panel is provided in a gap (2) of the fence (1). And a protective fence using a lattice panel, characterized in that a lattice panel (3) having a vertical diameter (Y) or a horizontal diameter (Y ') of the hole portion (4) of the panel is substantially the same. .

The material of the lattice panel (3) is not limited to metal, but may be plastic or wood, the thickness of the panel is 40 mm, and the longitudinal diameter (Y) of the hole (4) in the panel. Is also 40 mm, in the hole (4) of the lattice panel,
Insert a number of colorful marking members (5),
It is a symbol or design expression.

[0013]

According to the present invention, since the thickness dimension of the lattice panel (3) and the inner diameter dimension of the hole portion of the lattice panel are substantially the same, the present invention has Since it is possible to transmit from the direction orthogonal to the lattice panel while preventing the transmission from the left and right directions and the diagonal direction, the wind pressure during strong wind can be escaped from the opening and the panel can be prevented from being damaged. Scenery and light from orthogonal directions are transmitted, so there is no feeling of pressure, the sun's rays in the morning and evening are not blocked, the road surface dries quickly even after rain, and it is hygienic. By providing a plurality of colorful marking members on the part, letters, symbols, and a uniform design can be expressed on the lattice panel, and the manufacturing is inexpensive, which is extremely useful.
