Abstract

PROBLEM TO BE SOLVED: To provide a constitution, in which a color block preventing the insertion of high-heeled shoes and a wheel for a baby carriage and being molded of plastics is assembled as a grating used for a park, the periphery of a building, etc. SOLUTION: In the grating 1 with bearing bars 2 consisting of I-steel, the arched block using dimensions slightly larger than dimensions configured of twist bars 3 so as to bury openings formed by arranging the bearing bars 2 as outside dimensions is manufactured of plastics. Various patterns functioning as non-slips in combination or a hole for drainage is bored to the upper flat section of the block, and the block is fixed to an opening section so as not to slip off even when a large external force works.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a construction in which a plastic color block is later assembled to a steel plate grating which is a ready-made product.

[0002]

2. Description of the Related Art Conventionally, there is a method in which a groove is formed on an upper surface of a bearing bar constituting a grating, a coloring material is filled in the groove, and a coating color is applied with the groove to perform coloring.

[0003]

The main object of the present invention is to introduce coloring, which is an aesthetic element, as grating used in parks, buildings, etc., and conventionally, the size of the drainage opening is large. Therefore, there is a problem that high heels, wheels of a baby carriage, etc. get stuck, and the technology to be solved is to provide a configuration as a surface that is made of various non-slip patterns and retrofitted to a steel plate grating that is a ready-made product. It is an important subject.

[0004]

A technical means for solving the above-mentioned problem is to provide a grating having a bearing bar made of I-shaped steel in order to fill a gap in which the bearing bar is arranged, and to use a twist bar. The arched block whose outer dimensions are slightly larger than the size of the opening to be made is made of plastic, and the upper flat part is punched with various patterns that also serve as a non-slip, or various shaped drainage holes,
In order to fix the block in the opening so that it does not come off even when a large external force is applied, a recess for absorbing the swelling of the upper part of the bearing bar is provided on the shoulder on the upper surface of the arch, and a dent for absorbing the swelling of the twist bar. Along with the inside of the arch of the block, a stopper made of a leaf spring is also formed, which also forms an arch. The stopper is used to support the block upward, and the lower end of the stopper is provided at the lower part of the bearing bar. It is configured to engage with the step of the bulge. Incidentally, the block configuration is such that a plurality of segments can be connected and molded.

[0005]

With the above construction, the color block is assembled by press-fitting from the lower side of the grating, and the retaining of the upper block corresponds to the bulge of the upper stage of the bearing bar and the twist bar constituting the grating. The recess engages and functions including the restriction of movement in the X and Y directions. Next, a stopper made of a leaf spring, which is also in the form of an arch, is press-fitted from below, and the block is supported from below, and
The lower end is engaged with the step of the lower bulge of the bearing bar to form a lower retaining structure. Since it can form an opening of dimensions and is a molded product, it can form a non-slip pattern of any shape, it can also use a mesh to give water permeability, and it can be any color A ring can be provided.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a grating composed of a bearing bar 2 having an I-shaped cross section and a twist bar 3, and 4 denotes an arched cross section. A color block 5 made of a plastic molded product is a stopper made of a leaf spring also having an arch-shaped cross section. The details of the collar, the block 4 and the stopper 5 are shown in FIG.
6 is a concave portion for absorbing the upper bulging portion 7 of the bearing bar 2, 8 is a concave portion for absorbing the swelling of the twist bar 3, 9 is an upper pattern surface having an opening 10 for drainage, and then a stopper 5 , 11 is the same bearing bar 2
And a leg which engages with a step formed by the lower bulge 12 of FIG.

[0007]

As described above, according to the present invention, the ready-made grating serving as the base serves as a strength member.
Combination with a color block made of a plastic molded product that can be retrofitted with it can realize various slip patterns and various colors without impairing the original function of grating, and its fixing structure is easy The assembling work is completed by simply pressing the color block and the stopper in order from the back of the grating, and the force resisting the deviation is large because the plate spring that constitutes the stopper supports it with the vertical compression force. Further, as a characteristic of the retrofitting structure, it can be additionally attached to the existing grating, and has a high practical value.

Claims (1)

[Claims] In a grating having a bearing bar made of I-shaped steel, an arch-shaped section is formed by plastic molding or the like in order to fill a gap in which the bearing bar is arranged, and a bearing bar upper portion is provided on a shoulder of an upper surface of the arch. Provide a dent that absorbs the swelling of the twist bar, and provide a dent that absorbs the swelling of the twist bar on the other end surface, and, at the top, various patterns that also function as a non-slip, or a color block that has a drain opening hole. Along with the inside of the arch of the color block, a stopper made of a leaf spring, which also has an arch shape, is formed, and the arch-shaped leg of the stopper is open, and the tip of the leg is the bearing. A grating with a color block, wherein the grating is configured to engage with a step of a lower bulge of a bar.
