Also in the cover 11 having such a structure, since the aluminum frame material 1A except the upper and lower synthetic resin plates 3 and 3 and the packing 51, the intermediate rail 2 and the end plate 7 can be reused, the recycling rate can be improved. Since the upper and lower synthetic resin plates 3 and 3 have excellent corrosion resistance, they will not be corroded by dew condensation on the back surface. Since the upper and lower synthetic resin plates 3 and 3 and the end plate 7 are fixed by the fasteners, the assembly can be completed in a shorter time compared to the case of adhering, and when the synthetic resin plate 3 is damaged or deteriorated. It can be easily replaced.

When the cover 11 is lined up in an opening of a water treatment facility or the like, the receiving step 1b of the cover 11 adjacent to each other is overlapped with the overlapping step 1c of the other, and the packing 51 is interposed therebetween. Since the cover is sandwiched, the airtightness between the cover lids 11 is improved, and the packing 51 exerts a shock absorbing effect. Both ends in the longitudinal direction of the cover lid 11 are
As shown in FIG. 7, rubber packing 5 such as neoprene rubber
It is preferable to place it on the cover-cover receiving frame 21 in the opening with the two sandwiched therebetween. By doing so, the rubber packing 52 improves the airtightness between the cover-cover 11 and the cover-cover receiving frame 21, and exhibits a shock absorbing effect. To be done.

As is apparent from the above description, the cover according to the first aspect of the present invention has a high recycling rate, good corrosion resistance, is resistant to corrosion due to dew condensation, etc., and can be assembled in a relatively short time. Even if the upper and lower synthetic resin plates are damaged or deteriorated, they can be easily replaced with new synthetic resin plates and can be used for a long time, and the size can be easily changed. Further, the cover according to claim 2 has an effect that airtightness between the cover covers and between the cover cover and the cover receiving frame is enhanced by the packing, and a shock absorbing action is also exerted, and the cover according to claim 3 is It has substantially the same effect as the cover of claims 1 and 2.
