Description

[Detailed description of the invention] (Industrial field of application) This invention allows one of three or more gutter covers installed between horizontal load-bearing beams to cantileverly rotate around one of the joint end faces. This relates to a drop-top type gutter that can be raised.

(Prior Art) A gutter cover used in a conventional drop-cover type gutter has a rectangular cross-sectional shape in the vertical direction, and the surface of the horizontal load-bearing beam portion that is joined to the cover is also a plane in the vertical direction.

(Problem that the invention aims to solve) However, in the structure of such a gutter cover, the oblique side of the rectangle is longer than the long side, so after laying it in the gutter, it is difficult to pull it up by holding one side of the joint end surface and rotate it. That is impossible. For this reason, a method of lifting the lid vertically using a special removal tool and the mechanical force of a forklift truck or the like is used.

Even with this vertical lifting method, both jointed end surfaces are parallel, so the sliding friction resistance during lifting is large due to clogging with sand, soil, etc., and a very large operating force is required.

Therefore, an object of the present invention is to provide a drop-lid type gutter that can be moved from one side with a small force without requiring any special mechanical power.

(Means for Solving the Problems) The gist of the present invention will be explained below using reference numerals in the attached drawings. part 2, 3 between 2
More than one side gutter cover 3 is laid, and among the side gutter covers 3, one cover 3a that is not adjacent to the beam part 2 is installed.
Both joint end surfaces 4a of the lid 3a are formed as slopes such that the area of the bottom surface is smaller than the top surface of the lid 3a, and the joint end surfaces 4b of the lid 3b adjacent to both sides thereof are formed as slopes that correspond to the joint end surfaces 4a. It is.

(Function) During construction, the tops 5 of the drop-top type gutters are arranged so as to match the tops of the roads, and in-situ concrete is poured into the lower, fully open bottom 6, and the cast-in-situ concrete is This forms the gutter bottom. After that, three or more side gutter covers 3, 3 are placed between the beam parts 2.
Fit and install a and 3b.

When removing after installation, use the inclined joint end surface 4.
When you put your hand on the drainage/handhold notch 7 of the lid 3a having a handle and pull it up from one side, the lid 3a will slide out from the other lid 3.
The lid 3a rotates around the joint end surface 4b of the lid 3b, and the joint end surface 4a on the lifting side separates from the joint end surface 4b of the adjacent lid 3b without sliding, and the lid 3a can be easily removed. After removing one lid 3a between the beam parts 2, the other lids 3 and 3b can be easily removed.

(Example) In the illustrated example, the horizontal load-bearing beam part 2 is integrally molded between the tops of both ends of the left and right side walls 1, 1, but the horizontal load-bearing beam part molded separately is bolted to the left and right side walls. It may be joined by etc. In addition, the left and right side wall portions 1,
Although the bottom part 6 is completely open, a horizontal load-bearing beam part may also be provided in the bottom part, or the bottom part can be completely closed.

In the upper surface opening 8 formed between the beam parts 2,
Step portion 9 for supporting side gutter covers 3, 3a, 3b
has been formed. The wall 10 above the step 9 and in contact with the lid 3 is a plane whose cross section parallel to the beam 2 of the opening 8 forms a trapezoid whose lower side is shorter than its upper side, and the side surface of the gutter lid 3 conforms to this. It is a steep slope.

In the embodiments shown in FIGS. 1, 2, and 5,
Three side gutter covers 3 are placed in the opening 8, and the middle gutter cover 3a among the gutter covers 3 is a cover in which two joint end surfaces 4a, 4a are constituted by a linear inclined surface. , the joint end surfaces 4b of the side gutter lids 3b on the lid 3a side are slopes that correspond to the joint end surfaces 4a, respectively. Further, a notch 7 for draining water and for holding a hand is formed in the joint end surface 4a.

In the embodiment shown in FIG. 3, the side gutter cover 3a is provided with two holes 11 penetrating from the upper surface to the lower surface. This through hole 11 is used as a tool or a hand hole when turning and removing the lid 3a.

In the embodiment shown in FIG.
Two side gutter covers 3 are laid, among which one cover 3a that does not touch the beam 2 and the adjacent cover 3b are the same as the embodiment shown in Figs. 1, 2, and 5. The joint end surface 4 of the other lid 3 is a plane perpendicular to the upper and lower surfaces.

In the embodiment shown in FIG. 6, three side gutter covers 3 are installed in the opening 8, and the two joint end surfaces 4a, 4a of the middle side gutter cover 3a are larger in distance at the bottom than at the top. It is composed of a slope curved in a convex shape that becomes smaller, and the joining end surface 4b adjacent thereto is a curved surface matching the joining end surface 4a.

(Effect of the invention) As described above, in the present invention, both joint end surfaces 4a, 4a of one side gutter cover 3a of the three or more side gutter covers 3 laid between the horizontal load-bearing beams 2 are connected to the lid 3a. I made the slope so that the top surface is larger than the bottom surface, so
The lid 3a can be pulled up from one side, and the remaining lids can be easily removed in sequence from the opening created after removing the lid 3a, and the removal work of the gutter lid does not require the introduction of mechanical power. This can be done easily.
