The present invention relates to rain gutter lids installed on roadsides and grounds, and in particular, the height of rain gutter lids, which are relatively low due to road resurfacing or maintenance work, by allowing the height of the rain gutter lids to be adjusted without dismantling the sewers. It is related to a height adjustable rain gutter lid for easy adjustment.

Conventionally, when installing the rain gutter lid, as shown in FIG. 1, a plurality of projections 11b are formed on the side of the rain gutter lid 11 through which a plurality of inflow holes 11a are drilled, and the projection 11b may be caught. Forming a separate support plate 12 to put the support plate 12 on the upper end of the step (13a) of the sewer formed of concrete 13 or asphalt as shown in FIG. 2, and then rain gutter lid 11 on the top By placing a) the projection (11b) of the rain gutter lid 11 is to be fixed to the upper end of the base plate (12).

Therefore, such a structure is because the rain gutter lid 11 and the support plate 12 is placed on the upper end of the force 13a of the concrete 13, when the height of the concrete 13 rises due to road resurfacing or repair work, The height of the rain gutter lid 11 is relatively low, which hinders the driving of the vehicle, and causes direct and indirect damage to human life.

In addition, in order to raise the rain gutter lid 11 by the height of the concrete 13 or asphalt and the ground, the concrete 13 needs to be broken down to raise the stepped portion 13a. The curing period of the concrete 13 is required to take a lot of time, causing problems on the road such as traffic jams.

In order to solve this problem, the present invention fixes the frame to the sewer of the upper concrete, and combines the lid with bolts and nuts on the upper part to seat the lid of the rain gutter so that the rain gutter lid is inserted only between the frame and the lid. The height of the rain is automatically raised so that the rain gutter lid can adjust the height without breaking down the concrete.

In addition, the present invention is to allow the trivet such as the winch device to be fitted by forming a number of hanging grooves or protrusions and protrusions at the bottom of the lid to facilitate the separation of the lid from the frame.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 3, the present invention forms a flange 1a on the top of the rectangular frame 1 to face inwardly, drills several screw holes 1b, and reinforces ribs 1d to face the bottom. The fixing portion 1c is supported, and the lid 2 installed at the upper end thereof forms a flange 2a in the same shape and size as the flange 1a at the lower end to form several screw holes 2b. And, the bottom of the flange (2a) to form a plurality of hanging grooves (2c), the rain gutter lid (3) through which several inflow holes (3a) is formed to a size that can be seated inside the lid (2). . When assembling, as shown in Fig. 4, first, when the concrete (6) is molded, the frame (1) is buried at the bottom of the sewer to be fixed together with the curing of the concrete (6), and the lid rest (2) is installed on the upper flanges (1a) ( The screw holes 1b and 2b of 2a) may be fastened with bolts 4 and nuts 5, and then the rain gutter lid 3 may be seated inside the lid 2 to coincide with the upper end of the concrete 6. .

In the present invention configured as described above, rainwater that falls on the road or the ground exits into the sewer through the inlet hole 3a of the rain gutter lid 3 and the center of the lid gutter 2 and the frame 1.

In this state, when the height of the concrete 6 rises by “H” due to road repaving or maintenance work, lift the rain gutter lid 3 first, and then loosen the bolt 4 and nut 5. As shown in FIG. 5, the ring 8a formed on the trivet 8, such as a winch device (not shown), is lifted into the hanging groove 2c of the lid 2, and then lifted from the top of the frame 1. After installing a pair of height adjustment rings (7) (7 ') formed in the same shape and size as the flange (1a) as shown in Fig. 6, the lid rest (2) is again raised on the top thereof, and the height of the flange (1a) (2a) Tighten the screw holes (1b) (2b) (7a) (7´a) of the adjustment ring (7) (7´) with the bolt (4) and the nut (5), and then seat the rain gutter lid (3). do.

In this way, the height adjusting ring (7) (7 ') corresponding to the height (H) of the concrete (6) is inserted between the upper end and the lid support (2) while the frame (1) is fixed. , The rain gutter lid 3 also fits the height adjustment ring (7) (7´), so the rain gutter lid (3) also rises by the height (H) of the height adjustment ring (7) (7´). Coincides with the top of the concrete (6).

In addition, the present invention forms a locking groove (2c) at the bottom of the flange (2a) of the lid 2, insert a hook such as a winch device, and then lifts easily so that the frame (1) and the lid (2) is oxidized for a long time Even if it is fixed due to the action it can be easily separated from the frame (1).

Meanwhile, in carrying out the present invention, as shown in FIGS. 7 and 8, several protrusions 2d are formed or the protrusions 2e are formed in the flange 2a of the lid 2 so that the hook 8a may be caught. Even if formed, the same effect as the present invention can be obtained, which can be selected by the specification or order of the product.

As described above, the present invention embeds the frame 1 at the bottom of the sewer, which is formed of concrete 6, and integrally fixes the lid 1 with the rain gutter lid 3 seated thereon at the top of the bolt 4. And loosen the bolt (4) and the nut (5) by fastening with the nut (5), and then insert only the height adjustment rings (7) (7 ') between the frame (1) and the lid support (2). 3) Since the height of the concrete (6) is increased due to the road resurfacing or repair work, it is possible to simply adjust the height of the rain gutter lid (3) without breaking down the concrete (6).

In addition, the present invention does not require the curing period of the concrete (6), compared to the conventional, it can contribute to the cost savings due to the shortening of the air, and the separation of the lid 2 can easily contribute to the shortening of the air.

Claims (2)

The frame 1 is fixedly installed in a sewer such as a roadside or the ground to install a lid 2 on which a rain gutter 3 is seated on the top thereof, and a height adjustment ring between the frame 1 and the lid 2. 7) (7 ') height adjustable rain gutter lid that can adjust the height, the plurality of locking grooves (2c) formed on the lower end of the flange (2a) of the lid support (2) by the locking groove (2c) Height adjustable rain gutter lid, characterized in that configured to be fitted to the hook (8a) of the trivet (8). According to claim 1, wherein a plurality of projections (2d) and protrusions (2e) is formed in the inside of the flange (2a) of the lid (2) configured so that the ring (8a) of the trivet (8) can be fitted to the bottom surface Height adjustable rain gutter lid, characterized in that.
