Abstract

PROBLEM TO BE SOLVED: To provide a grating made of synthetic resin that is always likely to be kept clean by providing a phase difference between the upper face position of the cross girder and the upper face position of the stringer and making use of the condition that there is a larger possibility trashes adhered to the grids crop up to the surface between the higher girders and the lower girders, thus making it easy to pick them up to remove. SOLUTION: In this invention, a sheet-metal cross girder 2 arranged with a reciprocal distance placed in between and a sheet-metal stringer 3 arranged with a reciprocal distance placed in between are integrally molded by synthetic resin. Then, between the top face position of the cross girder and that of the stringer, a phase difference t is provided.

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin plate-shaped horizontal girder arranged at a distance from each other and a thin plate-shaped vertical girder arranged at a distance from each other. And grating integrally formed of synthetic resin. 2. Description of the Related Art Heretofore, as a synthetic resin grating, a structure in which the grating is formed by a perforated plate made of a hard synthetic resin is known (for example, registered utility model No. 3030).
646). The height of the upper surfaces of the horizontal and vertical beams of the grating is formed to be the same. [0003] By the way, in the above-mentioned known device, dust and the like are easily attached to the grids with a narrow interval.
If the height of the upper surface of the grating is the same to remove it, there is a possibility that it is difficult to remove it. The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a phase difference between an upper position of a horizontal girder and an upper position of a vertical girder. Is provided, it is easy to pinch and remove the dust and the like by utilizing the fact that the dust and the like attached to the grids are more likely to be exposed on the surface between the higher and lower girders. It is an object of the present invention to provide a synthetic resin grating that can be easily kept clean at any time. [0005] In order to achieve the above object, a synthetic resin grating according to the present invention comprises a thin plate-shaped cross beam and a thin plate-shaped mutually spaced gap. And a vertical girder arranged in a row is integrally molded with a synthetic resin, and a phase difference is provided between the upper surface position of the horizontal girder and the upper surface position of the vertical girder. FIG. 1 and FIG. 2 relate to an embodiment of the present invention. FIG. 1 is a plan view of a synthetic resin grating according to the present invention, and FIG. It is a partial enlarged view of a cross section. In the figure, reference numeral 1 denotes a grating made of synthetic resin, and the grating 1 is arranged in a thin plate shape and spaced apart from each other by cross beams 2, 2,. .. Are formed integrally with a synthetic resin. [0008] A phase difference t is provided between the upper surface positions of the horizontal beam 2 and the vertical beam 3. Also, horizontal girder 2 and vertical girder 3
Each side face is formed with a taper of about 4 degrees so as to taper from the upper part to the lower part. As the synthetic resin for forming the grating 1, for example, FRP having thermosetting properties, PVC having thermoplasticity, or the like is used. When the grating 1 made of synthetic resin having the above-described structure is installed in a general drain, dirt and the like are likely to adhere to the grids where the space between the horizontal girder 2 and the vertical girder 3 is narrow. By providing the phase difference t between the upper positions of the horizontal girder 2 and the vertical girder 3, the surface of dust or the like can be easily exposed on the upper surface of the lower vertical girder 3, or the finger can Can be picked up to remove the dust and the like, so that the dust and the like can be easily and easily removed at any time. The synthetic resin grating 1 according to the present invention can be used not only in general drains but also in water purification facilities, harbor facilities, chemical plants, fish farms, food processing plants and the like. It can also be used as a snowboard. FIG. 3 is an enlarged partial cross-sectional view of another embodiment of the grating 1, in which the upper surface position of the vertical beam 3 is higher than the upper surface position of the horizontal beam 2 by the phase difference t '. is there.
Also in this case, the surface of dust or the like can easily be exposed on the upper surface of the lower cross beam 2 or the dust or the like can be picked up by inserting a finger from the upper surface of the cross beam 2 so that the dust or the like can be picked up at any time. The dust and the like can be easily and easily removed. According to the present invention, the synthetic resin grating according to the present invention combines a thin plate-shaped horizontal girder arranged at intervals with a thin plate-shaped vertical girder arranged at intervals. It is molded integrally with resin, and a phase difference is provided between the top position of the horizontal girder and the top position of the vertical girder, so that dust and the like adhering to the grid are placed on the surface between the higher and lower girder. Utilizing the fact that the possibility of exposure is increased, the dust and the like can be easily pinched and removed, and the grating made of synthetic resin can be easily kept clean at any time.
