Description

[Detailed explanation of the idea] This invention relates to a water collection eyelid with a reinforced structure.

In general, conventional water collection lids have a basic structure in which a single piece of grating is placed on a receiving frame fixed to the periphery of the opening of a slot.

When particularly strong strength is required, the grating is reinforced with type steel.

The biggest problem with such a one-piece reinforced structure grating is that it is difficult and dangerous to open and close because it is heavy.

Further, the means for fixing the grating to the receiving frame to prevent the grating from jumping on the receiving frame and emitting metal impact noise when a vehicle passes by is also complicated and incomplete.

In view of this fact, the first object of this invention is to enable the grating to be opened and closed easily and safely while it is installed in the slot.

A second purpose is to enable the grating to be easily fixed in the slot.

The details will be explained below based on the drawings.

In FIG. 1, the main components of the water collection lid of the present invention include a receiving frame 1, a main beam 2, and a pair of left and right gratings 3a and 3b.

The receiving frame 1 is embedded and fixed to the opening periphery of a rectangular concrete slot 4 via anchor bolts.

The main beam 2 is made of I-shaped steel and is removably installed between the recesses 5.5 recessed in the left and right centers of the front side 1a and rear side 1b of the receiving frame 1.

The upper surface of this main beam member 2 is flush with the receiving surface of the receiving frame 1.

As shown in FIG. 2, each of the gratings 3a and 3b has a large number of bearing plates 7 made of ■-shaped steel installed at regular intervals in the front and back between the left and right end plates 6 and 6, respectively. It has a structure in which a plurality of cross bars 8 are orthogonally welded to the upper surface of the bearing plate 7.

The gratings 3a and 3b are laid on the upper surfaces of the receiving frame 1 and the main beam member 2 so as to be juxtaposed left and right.

Then, the outer end plate 6.6 of each grating 3a, 3b is attached to the left side 1 of the receiving frame 1 via the hinge 9.
C and the right side 1d, respectively.

As shown in FIG. 3, the hinge 9 has two connecting pieces 11 and 12 that are rotatable about a shaft 10 at the upper end.

Then, one connecting piece 11 is attached to the receiving frame 1, and the other connecting piece 1
2 are respectively fixed to the end plate 6, and the shaft 10
From the state in which the left and right gratings 3a and 3b are supported on the upper surfaces of the receiving frame 1 and the main beam 2 by slightly protruding from the outer upper surface 13 of the slot 4, a 180 0. °It is designed to be able to be rotated.

The inner ends of each of the left and right gratings 3 a and 3 b are
They are supported on the upper surface of the main beam member 2 so as to face each other in abutting manner, and are fixed with clamp fittings 14, respectively.

In FIG. 4, the clamp fitting 14 has a tightening bolt 16 screwed into the upper side of a piece 15 having a U-shaped cross section through a screw hole 17.

A connecting plate 19 is welded to the lower surface of the inner end of each grating 3 a , 3 b along the end plate 6 , and the U-shaped piece 15 is inserted through the grid openings 20 of the grating 3 a , 3 b. From the left and right inside of the main beam 2 made of shaped steel, the upper side 2a of the main beam 2
and the connecting plate 19, and insert the bolt 16.
By tightening each grating 3a,
The inner end of 3b can be fixed to the main beam 2.

Note that the structure of the hinge 9 can be freely changed, and may be of a hinge type.

Further, as shown in FIG. 5, the clamp fitting 14 also includes a piece piece 21 attached to an adjacent bearing plate 7 made of square steel.
Place the bolt 22 on the lower end of the piece 21 across the retainer through the lattice 20, and insert the bolt 22 erected and fixed on the upper side 2a of the main beam 2 into the screw hole 23 in the center of the piece 21. The bolt 22
Screw together the nut 24 from above to each grating 3a.
, 3b, the inner ends of which can be supported and fixed onto the main beam 2.

Further, the main beam member 2 may be a frame constructed by welding two angle members to have a rectangular cylindrical cross section, as shown in FIG.

As explained above, the water catchment cover according to this invention is
■It has a reinforced structure with a main beam 2 such as shaped steel installed in the center, but the grating is divided into left and right halves, and the left and right divided gratings 3a and 3b are supported on the main beam 2 separated from this. As a result, the left and right gratings 3a and 3b can be opened and closed separately, and the main feature is that the opening and closing operations can be performed easily and safely.

Moreover, when these gratings 3 a and 3 b are installed, their outer ends are pivotally connected to the receiving frame 1 fixed to the opening periphery of the slot 4 via hinges 9 , and their inner ends are pivoted to the receiving frame 1 via hinges 9 . Since the grating 3a3b itself is fixed to the main beam 2, it is easy to fix the grating 3a3b itself.
A, 3 and B no longer bounce around and make metal impact noises, and there are no longer cases of theft.
