[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to grating.

[0002]

2. Description of the Related Art Normally, grating is composed of a frame member formed in a predetermined groove lid shape and a plurality of cross bars arranged in the frame material at predetermined intervals, which are orthogonal to the cross bar. What is formed in a lattice shape by a twist bar is often used. Such a grating is placed so as to cover the opening of the gutter and prevents rain and dirt from falling into the gutter and guides rainwater into the gutter.

[0003] However, according to the grating of the above structure, earth and sand and the like easily fall from the gaps of the lattice, causing various problems. In addition, the walking stick of the old man, the heels of the high heels of the woman, the tires of the stroller and the bicycle, etc., which travel on the grating, are very dangerous. In addition, the surface may slip and fall over during rainfall.

[0004] For this reason, a method of narrowing the interval between the crosspieces arranged side by side is conceivable, but in this method, the number of crosspieces provided in the frame material increases, the number of steel materials used increases, and the cost increases. Not only that, the weight per unit area increases, which causes disadvantages in transportation and installation work.

In order to solve the above-mentioned problem, the present inventor is characterized in that main members having a substantially V-shaped groove at the top and having a substantially Y-shaped cross section are juxtaposed at predetermined intervals. (Japanese Utility Model Laid-Open No. 63-86186). According to this structure, a fine-groove lid can be obtained economically, but there is a new problem that soil and dirt accumulate in the groove and are easily soiled. Also, it has been difficult to completely prevent the tire from dropping and slipping on the surface.

[0006]

[Problem to be Solved by the Invention] This invention has been proposed in view of the above problems, and has a beautiful structure without slipping on the surface and excellent in safety. It is intended to provide grating.

[0007]

Means for Solving the Problems That is, the present invention provides:
In a frame material that defines a predetermined frame shape, in a grating in which a number of crosspieces having a groove on the top are laid in parallel, a coil-shaped material is fixed to the bottom surface of the groove of the crosspiece, and The present invention relates to a grating, wherein a sand-like non-slip material is integrally filled and fixed in the groove member so as to bury a coil-shaped material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the grating of the present invention, FIG. 2 is a plan view with a part thereof cut away, FIG. 3 is a sectional view thereof, and FIG. 4 is an enlarged sectional view of a main part thereof.

As shown in FIGS. 1 and 2, the grating 10 of the present invention is provided with a frame member 11 in which stainless steel, a casting or the like is defined in a predetermined groove cover frame shape, and provided in the frame member 11. It consists of crosspieces 12.

The crosspiece 12 has a substantially Y-shaped cross section with a groove 13 formed on the upper part, and a large number of the crosspieces are laid in parallel in the frame material 12. Reference numeral 14 denotes a twist bar that reinforces the strength of the grating 10 and is provided with the upper surface of the beam 12 orthogonal to the direction in which the beam 12 is bridged, and the surface of the grating 10 is formed in a lattice shape.

As can be understood from FIG.
A coil 15 is disposed on the inner bottom surface of the groove 13. The coil-shaped object 15 is formed by bending a steel wire such as stainless steel into a coil shape, similarly to the frame member 11, and is fixed in the groove 13 by welding or the like. The coil-like material 15 functions as an anchor for stably fixing the sand-like non-slip material 20 in the groove 13.

The sand-like non-slip material 20 is made of a mixture of sand-like ceramics and a synthetic resin material. As shown in FIG.
Is embedded and fixed. The sand-like non-slip material 20 is used not only to increase the surface area of the grating 10 to provide an anti-slip effect for tires of people and cars, but also to enhance the wear resistance and strength of the grating 10. It is preferable to fill the material 12 so as to slightly rise from the upper surface.

As the sand-like ceramic used for the sand-like non-slip material 20, a granular inorganic material is used, and trade name "Cera Sand" (manufactured by Bishu Mining) is suitable. Further, the synthetic resin material is used as a binder for the sand-like ceramic, and a known epoxy resin is preferable. The sand-like ceramic and the synthetic resin material are appropriately blended according to the durability required for the grating 10.
At this time, by adding a desired pigment or the like and coloring the surface, the surface of the grating 10 can be beautifully formed and its aesthetic appearance can be significantly improved.

[0014]

[Effect of the Invention] As shown and described above, according to the grating of the present invention, the tires of bicycles and automobiles come into close contact with each other because they have a very non-slip structure due to the sandy non-slip material, and the effectiveness of the brakes. Is also good.
In addition, since the gap between the crosspieces is small, the heels of women's high heels and the stroller tires do not fall, so it is easy to walk, and dirt and dirt are hardly dropped into the gutters. Furthermore, compared to conventional metal gratings, the water adhering to the surface is less likely to freeze and is thus safe. In addition, the sandy non-slip material can be appropriately colored, so that the grating surface can be beautifully colored and can be suitably used for parks, hotels, condominiums, and the like.
