Conventionally, manhole covers have been made of cast iron, but they often require troublesome treatment to prevent rust, and the manhole covers don't match well with the road pavement around them. If the lid of the manhole is made of concrete, there will be fewer problems with rust prevention treatment, and it will blend better with the road pavement, so it is desirable to make the lid of the concrete. A lid is suggested.

The concrete lids that have been proposed so far are made by pouring concrete into a cast iron frame, and are manufactured in a factory and are extremely heavy, making them difficult to transport to the facility site. The disadvantage is that it is expensive. Furthermore, if a concrete lid is to be used, it has been desired that the surface of the lid be formed to match the road paving material. However, since road pavement varies depending on the location, a problem arises in that if a concrete cover that is compatible with the pavement is produced in a factory, the cost will be significantly higher.

Inside this metal frame 1, a lattice-shaped reinforcing material 3, which is formed by joining a plurality of timbers 4, 4 vertically and horizontally, is provided integrally with the metal frame 1, and the upper surface of the reinforcing material 3 is connected to the frame. The reinforcing material 3 is lower than the upper surface of the reinforcing material 3 by a required height H.
The lower surface of the frame body 1 is raised higher than the lower surface of the frame body 1 by a required height h. Further, enlarged portions 5, 5 are formed at the lower ends of a suitable number of the crossing points of each of the timbers 4, 4, and screw holes 6, 6 are screwed into the enlarged portions 5, 5 from the lower surface thereof. It is set up.

0 and 10 are screwed into screw holes 6 and 6 screwed into the lower surface of the reinforcing member 3 through the formwork plate 9 and tightened and fixed. In this state, it is placed on a receiving frame 12 installed on the edge of the manhole 11. Then, concrete 7 is first filled into the frame 1 up to the height of the upper surface of the reinforcing material 3. Next, a paving material 8 made of substantially the same material as the paving material for the road surface layer is filled onto the concrete 7 to a height that is flush with the upper surface of the frame 1. Once the filled concrete 7 and paving material 8 have hardened, the lid is removed from the receiving frame 12, the bolts 10, 10 and the form board 9 are removed, and the holes for the bolts 10, 10 are filled with mortar 13. Fill each one. After that, the concrete lid is placed on the receiving frame again and used.

As explained above, the concrete lid of the present invention is provided with a reinforcing material formed by joining the timbers in a lattice shape in the annular frame formed with a substantially L-shaped cross section, and at the lower end of the intersection of the timbers. A screw hole was provided for attaching the formwork for concrete pouring, and the lower part of this frame was filled with concrete, and the upper part was filled with paving material, so the concrete lid was reinforced with the frame. The material is strong and durable, and screw holes for mounting the formwork are provided at the lower end of the intersection of the timbers, making it easy to install the concrete lid inside the frame. It is now possible to fill with concrete and paving materials, so there is no need to transport heavy concrete lids produced in factories to the site, making transportation and construction easy, reducing costs, and making it possible to use road paving at the site. It also has many advantages, such as being able to select and install paving materials, making concrete lids suitable for site conditions, and making facilities easier.
