Abstract

(57) [Abstract] [Purpose] The present invention is an idea to provide a manhole cover with an aesthetic design that matches the surrounding landscape at a low cost by combining an iron body and a special concrete decorative disk. [Structure] A manhole cover whose surface pattern can be changed at any time by attaching a designed special concrete decorative disk 2 to an iron cover body 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a manhole cover attached to a manhole of a sewer or an aquarium.

[0002]

[Prior art]

 Conventionally, this type of manhole cover is integrally made of iron, resin-con, or FRP, and when it is desired to change the surface pattern, it cannot be changed unless the entire cover is replaced. In addition, the iron manhole cover, which has been installed for many years, has a problem that the surface is polished by pedestrians and car tires, which causes a risk that the car and people are slippery when passing.

[0003]

[Problems to be solved by the device]

 In recent years, manhole covers on pedestrian paths or parks have also been required to have gorgeous designs that match the surrounding landscape. The designs range from flowers and birds that emphasize the local color, to seasonal products and special products. In the conventional method, when this type of manhole cover is produced in a small amount according to the demand of users, there is no choice but to specially manufacture the formwork by integral formation, which is expensive. The problem to be solved by the invention is how to provide something that is cheap, strong and aesthetically pleasing. We also try to solve the problem of slippery iron lids by changing the material.

[0004]

[Means for solving the problem]

 In order to solve the above problems, in the present invention, the iron lid main body 1 shown in FIG. 1 and the special concrete decorative disk 2 designed are combined. The material of the decorative disk is excellent in impact resistance, abrasion resistance, acid resistance, and fading resistance. Between the iron lid body and the decorative disk, the soft cement thin plate or rubber cushion material in Fig. 5 is used. 3 is sandwiched and safety is considered. Furthermore, the main body, disk and cushion material were firmly fixed with the connecting metal fittings shown in Fig. 5, and the durability after installation was fully considered.

[0005]

[Effect of device]

 According to the present invention, the iron main body can be manufactured in an integrated manner with a standardized size and shape, so that the cost is reduced. In addition, since the decorative disk can use a rubber mold at any time, it can meet the needs of customers at low cost regardless of small-volume production or mass-production. In addition, in the present proposal, the iron body will be used as it is, and according to the four seasons or in accordance with changes in the surrounding landscape, only the decorative disk will be replaced, and the effect of adapting to the surrounding landscape will also be demonstrated.
