Abstract

The utility model relates to a cast iron concrete gully grating, and a grating body of which is formed by compounding a cast iron framework and concrete. The cast iron framework is composed of a protective frame around the grating body, the hole walls of water leaking holes and reinforcing ribs, and the concrete is entrapped at the periphery of the cast iron framework. The utility model has the advantages of reasonable structure, novel design, low manufacture cost, firmness and high durability, and is not easy to break. The cast iron concrete gully grating of the utility model which is used not only beautifies environment, but also avoids the phenomenon that a cast iron gully grating is stolen. The cast iron concrete gully grating is an ideal renewal product of the existing cast iron gully grating.

Description

Cast iron concrete drain cover

The utility model relates to the drain cover of a kind of road both sides draining, particularly a kind of cast iron concrete drain cover.

The draining grate that the urban road both sides are provided with generally all is to adopt the cast iron integral cast to form.Drain cover breakage, the phenomenon of losing happen occasionally.Cause the pedestrian thus and fall into inspection shaft, cause casualty accident.

The purpose of this utility model is at deficiency of the prior art, and a kind of novel cast iron concrete drain cover is provided.

Technical solution of the present utility model is: cast iron concrete drain cover; form by base and grate body two parts; the grate body of drain cover is composited by cast iron skeleton and concrete; the hole wall of grate body periphery bearer bar and leaking hole is the cast iron structure; leaking hole is connected by reinforcing rib with grate body periphery; constitute whole cast iron skeleton, concrete is included in cast iron skeleton periphery.

Further describe the utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional view of Fig. 1.

1, bearer bar 2, reinforcing rib 3, concrete 4, leaking hole

As shown in Figure 1 and Figure 2, cast iron concrete drain cover is made up of base and grate body two parts, and base is identical with the base of existing drain cover, and the grate body of drain cover is composited by cast iron skeleton and concrete.The grate body is provided with a plurality of leaking holes 4, and the hole wall of leaking hole 4 is connected by reinforcing rib 2 with grate body periphery bearer bar 1, forms the cast iron skeleton jointly, and concrete 3 is filled in the leaking hole periphery.

The utility model cast iron skeleton adopts No. 22 iron casting moulding, and concrete is selected high strength cement for use No. 600.During making, the cast iron skeleton of casting is put into model, add the good strong concrete of proportioning, vibrate once-combined moulding through machinery.The drain cover that processes, the weight of cast iron skeleton only account for about 1/4 of gross weight, can save steel greatly on the one hand, reduce cost, and it is low to usurp value on the other hand, can avoid taking place the stolen phenomenon of drain cover.

The utility model is rational in infrastructure, modern design, and cost of manufacture is low, and weight capacity is strong, non-slip, noiselessness.Adopting this novel cast iron concrete drain cover, both beautified the environment, stopped to steal the phenomenon of cast iron drain cover again, have good social benefit, is the existing desirable regeneration product of cast iron drain cover.

Claims

1, a kind of cast iron concrete drain cover; form by base and grate body two parts; it is characterized in that the grate body is composited by cast iron skeleton and concrete; the bearer bar of grate body periphery and the hole wall of leaking hole are the cast iron structure; leaking hole is connected by reinforcing rib with bearer bar; constitute whole cast iron skeleton, concrete is included in cast iron skeleton periphery.
