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.
The purpose of the present invention is that there is no unevenness in the lightweight and fireproof connecting roof and tight frame, so it is possible to adjust slightly to the left and right after construction, and even if the tight frame and light weight and fireproof connecting roof are not orthogonal, construction can be done And the surface is flat, so that the heat insulating material will not break. Furthermore, since the working width can be changed by flattening the surface, the product cost and the construction capability can be improved, and the overall cost can be reduced.
Further, since the surface is flat and there is no groove, it is possible to bond the heat insulating material.
In addition, by providing a lightweight and fire-resistant connecting roof that allows the use of ceiling hanging brackets, simplifies the installation of drain discharge members, and makes the surface flat so that it can be used anywhere for fixing screws. is there.

The first invention of the present invention for solving the above-mentioned problems is a lightweight and fireproof connecting roof as described in claim 1, and is as follows.
The roof plate is formed with leg-shaped rib portions having vertical wall portions bent on the lower surface at appropriate intervals, and the upper ends of the vertical wall portions are bent horizontally to make the space between the leg-shaped rib portions flat. , on both ends, to form a leg-like rib portion fitting bent edge or shingle underside support edge polymerization edges, the leg-like rib portion fitting folding Kyokuen is between the vertical wall portion of the leg-shaped rib portion It fits into either disposed in a recess formed in the tight frame, or the roof plate lower face supporting edge polymerization edges together is connected as a shingle and rests polymerization, coupling comprising a roof plate and tight frame the connecting A roof is attached to the housing, and a leg-like rib portion formed with a roof plate is fitted to the lower surface of the concave portion formed in the tight frame , and attached by a required attachment means, and against the inner bottom of the concave portion of the tight frame. In addition, the expanded bottom portion of the leg-shaped rib portion of the roof plate has a gap. Arranged fitted on and attached rests and integral with the roof plate fitting convex portion formed on the tight frame a flat surface between each leg shaped rib portion of the roof plate, the roof having the flat surface It is the structure which adhered the heat insulating material to the board .

In addition to the invention according to any one of claims 1 to 3 , a ceramic incombustible plate, a heat-resistant and heat-insulating plate, and a waterproof material are sequentially laid in a laminated form on the roof plate, It is the structure to do.

Since the lightweight and fireproof connecting roof according to the present invention has the configuration as described above, the following effects can be obtained.
(1) Since there is no groove portion on the surface, water droplets accumulate in the groove portion, and the heat insulating material is not broken by the groove during the operation.
(2) Since there is no unevenness on the lightweight / fireproof connecting roof and tight frame, some adjustment to the left and right is possible after construction, and construction is possible even if the tight frame and lightweight / fireproof connecting roof are not orthogonal.
(3) Since the surface is flat, the heat insulating material is not cracked.
(4) Since the working width can be changed by flattening the surface, the product cost and construction capacity can be improved, and the overall cost can be reduced.
(5) Since the surface is flat and there is no groove, it is possible to bond the heat insulating material.
(6) The use of a ceiling hanging bracket becomes possible, the attachment of the drain discharge member is simplified, and the surface is flat, so that the fastening screw for the product can be used anywhere.

The roof plate is formed with leg-shaped rib portions having vertical wall portions bent on the lower surface at appropriate intervals, and the upper ends of the vertical wall portions are bent horizontally to make the space between the leg-shaped rib portions flat. , on both ends, to form a leg-like rib portion fitting bent edge or shingle underside support edge polymerization edges, the leg-like rib portion fitting folding Kyokuen is between the vertical wall portion of the leg-shaped rib portion It fits into either disposed in a recess formed in the tight frame, or the roof plate lower face supporting edge polymerization edges together is connected as a shingle and rests polymerization, coupling comprising a roof plate and tight frame the connecting A roof is attached to the housing, and a leg-like rib portion formed with a roof plate is fitted to the lower surface of the concave portion formed in the tight frame , and attached by a required attachment means, and against the inner bottom of the concave portion of the tight frame.
