Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a metal fitting for attaching a cover plate to a grating installed in a side gutter.

(Prior art and its problems) Conventionally, a grating has been installed on the top side of the survey groove, and since this grating is formed in a lattice shape, there are openings between the gratings. It is desirable for gratings installed in areas with heavy foot traffic to have fewer openings, as heels and the like can get stuck in the gratings, which can be dangerous.

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and aims to provide a metal fitting that can easily attach a cover plate to the upper surface side of a grating. Its gist is that it is a metal fitting for attaching a cover plate to a grating formed in a grid shape by I-shaped bars and cross bars and installed in a gutter.
The metal fitting includes a fixed piece fixed to the cover plate;
When the cover plate is attached to the grating in a state where the cover plate is fixedly fixed to the cover plate in a pair facing each other, the support piece portion is provided which can be clamped to the cross bar and abut against the side surface of the I-shaped bar. be.

(Function) The fitting has a fixing piece and a support piece, and the fixing piece can be fixed to the flat cover plate by means such as welding, and the fitting is fixed to the cover plate and the cover plate becomes a grating. When attached to the grating, the supporting pieces of the metal fittings sandwich the crossbars that make up the grating, and are firmly attached to the crossbars, and at the same time abut against the sides of the I-shaped bars.
The cover plate is firmly attached to the grating via the metal fittings without causing lateral displacement.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

Figure 1 shows a metal fitting for attaching a cover plate to a grating. A plurality of metal fittings 1 of the same shape are prepared, and the upper surface side of the metal fitting 1 is a horizontal fixing piece 1a. A support piece 1b is integrally formed with an inclined support piece 1b at one end of the piece 1a, and an expanding piece 1c is formed integrally with the lower end of the support piece 1b at an opposing angle of inclination.

The engagement fitting 1 formed in this manner is fixed by means such as welding to the back side of a cover plate 2 made of stainless steel or the like in a flat plate shape, and the fixing piece 1a is attached to the cover plate 2. 2 is welded and fixed.

The fixing position of each engagement fitting 1 to the cover plate 2 is as follows:
For example, as shown in the plan view in FIG. 2, a pair of engaging metal fittings 1 are arranged facing each other in a staggered manner. The crossbar 6 of the grating 3 can be held between the support pieces 1b, 1b of the engagement fitting 1. Incidentally, projections 2a, 2a, 2a projecting upward in a staggered manner are formed on the surface side of the cover plate 2, and the projections 2a have an anti-slip effect.

As shown in FIG. 3, the grating 3 is installed on the upper surface side of a surveying groove, etc., and the inside of the end plate 4 forming the outer frame has I-shaped sections at predetermined intervals in the lateral direction. I-shaped bar 5, 5,
5 are arranged, and each I-shaped bar 5,
5, cross bars 6, 6, 6 are disposed orthogonally at predetermined intervals to form a grating 3.

As described above, the cover plate 2, which is disposed on the upper surface side of the grating 3 and is formed into a plate shape with a size that can cover the upper surface of the grating 3, has a plurality of engagement fittings 1 arranged in a staggered manner as described above. FIG. 4 shows a perspective view of the main part of the engaging metal fitting 1 attached to the grating 3. The supporting pieces 1b, 1b of the engaging metal fitting 1 can sandwich the cross bar 6. This allows the engaging metal fitting 1 to be firmly attached to the cross bar 6. Also, at that time, the engaging metal fittings 1,
The opposing inner side surfaces of the gratings 1 abut against the side surfaces of the I-shaped bars 5, thereby preventing lateral displacement when the cover plate 2 is attached to the grating 3.

Incidentally, FIG. 5 shows an enlarged view of the state in which the crossbar 5 is clamped.

If the engaging metal fittings 1 are appropriately fixed to the back side of the cover plate 2 in this way, the grating 3 can be attached in that state.
By pressing down on the cover plate 2 from the upper surface side, each engagement tool 1 is firmly clamped to the cross bar 6 of the grating 3, and the cover plate 2 is integrated with the grating 3. The cover plate 2 is easily installed on the grating 3, and the grating 3
The top side can be covered, and in that case, cover plate 2
As a result, the lattice-shaped openings of the grating 3 are hidden, and even when a person walks on the top surface of the cover plate 2, the heel or the like will not get caught, increasing safety. Moreover, on the top surface of the cover plate 2, a non-slip protrusion 2a,
2a is formed, the cover plate 2 may be damaged due to rain etc.
Safety is ensured by preventing slippage even when the surface is wet.

In addition, as shown in FIG.
By arranging a pair of opposing arrangement intervals equal to the width of two I-shaped bars 5, the two gratings 3,
3, the two I-shaped bars 5, 5 can be clamped by a pair of engagement fittings 1, 1, and a cover can be inserted from above at the joint between the two gratings 3. By attaching the plate 2, the joint portion of the gratings 3, 3 can be firmly connected, and the connectivity of the gratings 3 can be ensured.

The shape of the engagement tool 1 can be changed, and the expansion piece 1c may have a shape that allows the engagement tool 1 to easily engage with the crossbar 6 when attaching the cover plate 2 to the grating 3. , can be formed in the expanding piece portion 11c as shown in FIG. 7, and the shape of the engaging metal fitting 1 can be changed as appropriate.

In this way, in this example, the flat cover plate 2
The engaging metal fitting 1 can be easily fixedly disposed on the back side of the grating 3 by welding or the like, and the cover plate 2 can be easily attached to the upper surface side of the grating 3 later through the engaging metal fitting 1. It is possible to cover the side well with the cover plate 2, and it is possible to improve the appearance of the upper surface of the groove and to ensure safety.

Incidentally, it is possible to fix the engaging tool 1 to the cover plate 2 in advance by adapting it to the shape and dimensions of the grating 3, and in that case, the cover plate 2 can be pressed down from the upper surface side of the grating 3 at the site. The upper surface side of the crater 3 can be easily covered.

(Effect of the invention) The grating fitting of the present invention is a fitting for attaching a cover plate to a grating formed in a lattice shape by an I-shaped bar and a cross bar and installed in a measuring groove, When attaching the cover plate to the grating with the fixing piece fixed to the plate and the cover plate fixed in a pair facing each other,
By providing a support piece that can be clamped to the cross bar and abut on the side surface of the I-shaped bar, the fixed piece can be easily integrated with the cover plate by means such as welding, and the upper surface of the grating can be easily integrated with the cover plate by means such as welding. By pressing down on the cover plate from the side, the support piece is clamped to the crossbar that makes up the grating, and the cover plate can be firmly attached to the grating later through the metal fittings, and the top side of the grating can be attached to the cover plate. This has the effect of being able to cover the area well and ensure safety.
