Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a gutter cover lattice body embedded in a concrete gutter cover.

(Prior Art) Generally, a concrete gutter cover has a lattice body embedded within the gutter cover main body. This lattice body has the function of collecting rainwater flowing over the concrete gutter cover into the gutter. The present applicant first penetrated a plurality of horizontal rods connected to reinforcing bars in the gutter cover body through a plastic grid body so that the plastic grid body was buried in the gutter cover with high mechanical strength. We have proposed a concrete gutter cover made of concrete (see Utility Model Application Publication No. 178483/1983). On the other hand, in recent years, gutter covers have been used whose upper surfaces are slanted downward toward the side opposite to the road so that rainwater and garbage on the road can easily flow into the gutter. Since the upper surface of such a gutter cover is inclined, the lattice body is also buried in an inclined manner along the slope of the upper surface. However, in this case, since the plurality of horizontal rods run almost horizontally within the side lid body, it is necessary to shift the through holes of the lattice body, and since this shift varies depending on the degree of inclination, it is necessary to It was necessary to prepare a separate grid for In addition, even if the top surface of the gutter cover is horizontal, the depth of the reinforcing bars will vary depending on the thickness of the gutter cover, so the position of the through holes in the gutter body must also be changed, so separate gutter bodies are prepared for each thickness of the gutter cover. I needed to. For this reason, it was necessary to always prepare a plurality of types of grid bodies, which was uneconomical.

(Purpose of the invention) An object of the invention is to provide a gutter cover lattice body that can be applied to concrete gutter covers having various inclinations or thicknesses with one type of lattice body.

(Structure of the invention) The gutter cover lattice body of the present invention is composed of a lattice body having through holes through which horizontal rods embedded in a concrete gutter cover body and connected to reinforcing bars in the gutter cover body pass through. This through hole is characterized by being vertically elongated and opening at the lower edge of the lattice body.

According to this structure, even if the upper surface of the concrete gutter cover is sloped or has different thicknesses, the plurality of horizontal rods can be displaced and penetrated within the vertically elongated through hole. It can be applied to a gutter cover having a gutter cover, and since this through hole is opened at the lower edge of the lattice body, the horizontal rod can be easily passed through this opening, so the forming work of the gutter cover can be done quickly. be able to.

(Example) An example of the present invention will be described in detail with reference to the drawings. Figs. 1 to 3 show a concrete gutter cover 12 using a gutter cover grid body 10 according to the present invention, and this gutter The lid 12 consists of a concrete gutter lid main body 16 in which reinforcing bars 14 are embedded, and a lattice body 10
is embedded in this gutter cover body 16. The upper surface of the gutter cover body 16 is gradually inclined downward from the roadway 18 side toward the sidewalk 20 side.

As shown in FIGS. 4 to 7, the lattice body 10 of the present invention has a through-hole through which the reinforcing bars 14 in the gutter cover body 16 are inserted and the tubular horizontal bars 22 are connected by welding or the like. It consists of a plastic grid body 26 with holes 24. This through hole 24 is vertically elongated and opens at the lower edge 26a of the lattice body 26, particularly as shown in FIGS. 5 and 6.

As can be seen from FIG. 2, when the upper surface of the gutter cover main body 16 is inclined, the plurality of horizontal bars 22 connected to the reinforcing bars 14 and running horizontally are connected to the gutter cover main body 16.
Although the depth positions from the top surface of the through-holes 24 are different, since the through-holes 24 are vertically long, the horizontal rods 22 can be displaced within the through-holes 24 according to the depth positions and can be easily passed through the through-holes 24. Also, since the through hole 24 is open at its lower end, the through hole 24 is
The horizontal rods 22 can be passed through the grid body 26 by aligning the openings 24a of the grid members. Therefore, the work when forming the concrete gutter cover becomes easier.

In the above embodiment, the lattice body of the present invention is applied to a gutter cover with an inclined top surface, but it goes without saying that the lattice body of the present invention can also be applied to a gutter cover with a horizontal top surface. . In this case, since the position of the reinforcing bars differs depending on the thickness of the lid, it is advantageous for the through hole 24 to be vertically long.

(Effect of the invention) According to the invention, as described above, when the upper surface of the concrete gutter cover is sloped or the thickness is different, the plurality of horizontal rods can be displaced and penetrated within the vertically long through hole. Therefore, just by preparing one type of grid body, it can be applied to gutter covers with various slopes or thicknesses.Also, since this through hole is opened at the lower edge of the grid body, it can be used through this opening. Since the horizontal rod can be easily penetrated, there is a practical benefit in that the gutter cover can be formed quickly.
