BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a concrete product for draining rainwater, such as a concrete product for a culvert, a concrete product for a circular channel, a cover for a gutter, etc. The present invention relates to a protective member, which is processed simultaneously with the production of a concrete product and is used integrally with the concrete product. The configuration is characterized by having a cover member and a frame member attached to the back surface of the cover member. The materials used for these include steel, stainless steel, cast iron, ductile, aluminum, wood, rubber, reinforced plastic, and the like. Preferably, in terms of ease of processing, material cost, strength, etc., FRP (Fiber reinforcement pl
astics). The cover member is made of a flat plate member, and a side plate may be provided upright on a part or all of the edges of the plate member depending on the intended use. For example, in the case of a concrete product such as a lid which may be exposed to the weather at any time or may be repeatedly used for laying and removing the side surface, a side plate may be attached so that the side surface of the concrete product can be protected. . Further, as shown in FIG. 10, it may be provided up to the bottom surface.
The size and thickness of the cover member are not particularly limited.

Further, a concave and convex pattern can be formed on the upper surface of the cover member in order to improve aesthetics, promote an advertisement, or provide a function such as anti-slip. Of course,
These patterns are not particularly limited, and for example, it is possible to form a concave and convex shape of a flower pattern to improve aesthetics, or to give a badge of a municipal or the like for advertisement. Further, a plurality of circular or square concave portions can be provided to prevent slippage. In addition, if the material to be used is selected, various colors of the cover member itself can be selected, and the aesthetics can be further improved.

[0013] A grip portion may be formed on the upper surface of the cover member so that the concrete product can be easily held. If the grip portion is formed, attachment and detachment of the concrete product can be easily performed. Although the shape of the grip portion is not particularly limited, if a concave groove is provided on the upper surface as shown in FIG. 5 and a rod is provided in the concave groove, it is easy to firmly grasp the rod and apply force. A grip can be formed.

On the other hand, the frame member replaces a conventional reinforcing bar inserted inside a concrete product for reinforcement. This frame member may be formed in a rib-shaped plate as shown in FIG. 2 or may be formed as a rod-shaped body as shown in FIG. In addition, this frame member may be manufactured integrally with the cover member in advance, or may be assembled in another process after manufacturing only the cover member.

The concrete product protective member thus produced is formed so that the frame member is present inside the concrete product, and the cover member is formed so as to cover the upper surface of the concrete product to obtain a surface protective concrete product. . The formation method is not particularly limited.

Since the surface protective concrete product thus produced has a cover member provided on the upper surface, it is possible to prevent erosion and corrosion caused by wind and rain or a snow melting agent. Also,
If the side surface is also protected by the cover member, it is possible to prevent the concrete product from being damaged by laying or removing the concrete product when the concrete product is laid or removed.
On the other hand, since the frame member is provided inside the concrete product, the strength of the concrete product can be secured at the same time as in the case of the conventional reinforcing bars.

Further, in order to guide rainwater or the like on the upper surface to the drainage channel, a water channel may be attached to the back surface of the cover member so as to have a water hole from the upper surface of the cover member to the lower surface of the concrete product. For example, this can be achieved by attaching a tubular body to the back surface of the cover member so as to have water holes from the upper surface of the cover member to the lower surface of the water passage section. Thus, the water holes can be formed inside the concrete product, so that the rainwater accumulated on the upper surface of the cover member can be guided to the drainage channel through the water channel. The water holes may be formed inside the above-described frame member as shown in the figure.
For example, if this is used for a lid such as a gutter, it can be used instead of the conventional grating.

A preferred embodiment of the concrete product protective member manufactured by the above technical concept will be described with reference to the drawings.

(Embodiment 1) FIG. 1 is a perspective view of a concrete product protective member 100 of the present invention according to Embodiment 1. FIG. The protection member 100 for concrete products of the present invention includes:

The water passage hole 41 penetrates the upper surface of the cover member 10 and is formed so that water such as rainwater accumulated on the upper surface of the concrete product protection member 100 can be guided into the side groove through the water passage hole 41. is there. The water passage 42 on the upper surface is formed in the same size as the above-mentioned circular concave portion 13 so as to be inconspicuous.

The concrete product protective member 100 produced as described above is made into a surface-protected concrete product (a gutter lid) by the following method. First,
The concrete product protection member 100 is housed upside down in a container 60 having substantially the same size that can house the protection member 100 (FIG. 3). Then, ready-mixed concrete is poured into the back surface of the cover member 10 so as to include the frame member 20 (FIG. 4). At this time, it is necessary to prevent the water hole 41 from being closed by the concrete. Then, after the concrete is completely poured between the frame members 20, the concrete is left to cure for several hours, and then the surface-protected concrete product 11 is removed from the container 60.
Remove 0 and complete.

Since the lid thus completed is covered with the plate-like cover member 10 made of FRP on the upper surface and side surfaces, it is possible to effectively prevent erosion and corrosion from wind and rain or a snow melting agent. it can. In addition, even when laying or removing the concrete product 50, it is possible to prevent the concrete product 50 from being damaged by the cover member 10 even if the bumper collides with the surrounding area or comes into contact with the surrounding area. Further, as shown in FIG. 5, the work of laying and removing can also be easily performed by using the grip portion 30 formed on the cover member 10. Therefore, it is not necessary to perform a complicated operation such as using a dedicated tool in a gap formed at both ends of a concrete product as in the related art. Further, since the frame member 20 is provided inside the concrete product 50, it is possible to provide the surface protection concrete product 110 having a strength that can be used without using a reinforcing means inside with a reinforcing bar or the like.

Further, since the water holes 41 are formed from the water holes 42 formed on the upper surface of the cover member 10 to the lower surface of the concrete product 50, the water on the upper surface of the concrete product 50 can be guided to the drainage channel. . Moreover, since the water can be guided into the gutter without contacting the concrete portion, the concrete product is not corroded by rainwater or the like. Further, since a plurality of such water passage holes can be formed, the drainage efficiency is higher than in the conventional case.
