Description

  The present invention relates to a lightweight and fire-resistant connecting roof that uses what is usually called a deck plate, for example, a steel structure or the like that uses a flat surface of a deck plate having a flat upper surface.

Conventionally, a leg-shaped rib portion having a roof plate lower surface support edge is formed at one end portion of the roof plate, and a bent edge for fitting the leg shape rib portion or a roof plate lower surface support edge overlapping edge is formed at the other end portion. A connecting roof in which the bent edge is fitted to the rib portion or the roof plate lower surface support edge is overlapped with the roof plate lower surface support edge to connect the roof plate, and the roof plate is driven. In a lightweight and fireproof connecting roof composed of a tight frame for attaching to a body, a leg-like rib fitting recessed lower surface formed on the tight frame is attached to the fuselage with required attachment means, and the leg-like ribs A concave / convex portion for fitting a tight frame formed between the leg-shaped rib portions of the roof plate, and a roof formed on the tight frame. Fit the concave and convex parts for plate fitting together. Unishi was lightweight refractory connecting roof (e.g., see Patent Document 1) exists.
Japanese Patent No. 3453653 (see paragraphs of claims, paragraphs {0006} to {0011} of embodiments of the invention, and FIGS. 1, 7, 8, and 10)

However, since the conventional lightweight and fireproof connecting roof has grooves formed on the surface thereof, it is extremely difficult to bond the heat insulating material to the upper surface, and thus, the screwing is performed without bonding. Moreover, since it fixes using the said groove | channel for fixation with a tight frame, there exists a fault that it cannot construct unless the tight frame is direct.
Furthermore, since there is a groove portion on the surface, there is a drawback that water droplets accumulate in the groove portion, and the heat insulating material is broken by the groove during the operation.
