Abstract: A full contact pontoon floating deck is revealed. An upper and a lower assembly grooves are disposed concavely on an upper and a lower ends of each of two sides of a pontoon respectively. A connecting rod is connected to the two pontoons by upper connecting members and lower connecting members. One end of the upper connecting member and one end of the lower connecting member are connected to the upper and the lower assembly grooves of the pontoon respectively by upper and lower assembly members while an upper and a lower connecting portions on the other end of the upper and the lower connecting members are connected to an upper and a lower connecting grooves of the connecting rod respectively. Thereby the tight connection forms a fully-sealed design with good support strength. No vapor space is formed so that environmental requirements are met.

Abstract: A floating cover roof for a storage tank has a frame assembly and multiple floating units. The frame assembly has a holding frame and an outer rim. The holding frame has multiple longitudinal beams and transverse beams. Each longitudinal beam has a connecting seat, a first holding segment and a second holding segment. Two of the transverse beams are connected to two adjacent longitudinal beams to form a locating area between the beams. The floating units are mounted in the locating areas of the frame assembly, are connected to the beams of the holding frame and each has an outer casing and a body. The outer casing is mounted in one of the locating areas of the holding frame, is connected to the adjacent beams and has a casing body and a top board. The body is mounted in the outer casing between the casing body and the top board.
