Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a concrete cover body that covers side gutters, public gutters, etc.

(Problems to be solved by this idea) In order to enable traffic to pass over side ditches, communal ditches, etc.
The tops of these grooves are covered with concrete covers. In order to create a sense of unity with the surrounding road surface, such a lid body is made of asphalt cast tiles or blocks laid on concrete so that it does not look out of place with the surrounding area.

However, for example, during road surface repair work, when existing asphalt is destroyed and new tiles are destroyed, the asphalt portion may be damaged. In addition, asphalt was adhered to the surface and could not be easily removed.

This idea was made to solve the above problems, and provides a concrete lid body that allows the existing decorative layer to be easily removed without damaging the underlying concrete layer. It is.

(Means for solving the problem) The concrete lid body according to this invention has a rectangular plate-shaped concrete part surrounded by an outer peripheral frame, and the upper side of the outer peripheral frame is made slightly higher than the upper surface of the concrete part. An anti-adhesion material is placed inside the part of the outer frame that protrudes from the concrete part, a protective layer of sand or the like is formed on the concrete part, and a decorative layer of asphalt, tile, etc. is applied on top of that.

The adhesion prevention material prevents the decorative layer from adhering.

The protective layer prevents the concrete from being damaged.

(Example) Hereinafter, this invention will be explained in detail based on an example shown in the drawings.

In the figure, 1 is a side gutter, on which a concrete cover 2 is placed. The concrete lid body 2 has a rectangular plate-shaped concrete portion 3 surrounded on all four sides by a metal outer peripheral frame 4. The upper side of the outer peripheral frame 4 protrudes slightly higher than the upper surface of the concrete part 3, so that the concrete part 3 and the outer peripheral frame 4 form a box shape.

An anti-adhesion material 5 is disposed inside a portion of the outer peripheral frame 4 that projects upward from the concrete portion 3, that is, on surfaces facing each other. As the adhesion prevention material 5, paint such as paint may be applied, gummed tape, paper tape, or vinyl tape may be applied, or a plastic board, a plywood board, etc. may be provided.

A protective layer 6 is formed on the concrete part 3. The protective layer 6 protects the concrete part 3 and prevents the decorative layer 7 applied thereon from adhering to it.
Sawdust etc. can be used.

A decorative layer 7 of asphalt, tile, block, etc. is applied on the protective layer 6 to ensure unification with the surrounding surfaces.

In the concrete lid body 2 as described above, when repair work is performed by once destroying the decorative layer 7, the protective layer 6 protects the concrete portion 3 when the decorative layer 7 is destroyed. Further, the adhesion prevention material 5 prevents the decorative layer 7 from adhering to the outer peripheral frame 4, and can be easily peeled off.

When applying a new decorative layer 7, the protective layer 6 may be formed again, and the decorative layer 7 may be formed thereon.

(Effects of the invention) This invention has the above-mentioned configuration, and since the anti-adhesion material is provided inside the outer peripheral frame, the decorative layer can be easily peeled off. This prevents the concrete from being damaged when the decorative layer is destroyed.
