Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fireproof connection structure for an exterior plate, and more specifically, to a technique for significantly improving the workability while having sufficient fireproofness. is there.

[Prior Art] Conventionally, a fitting convex portion 1 is formed at one end of a fireproof exterior plate, and a fitting concave portion 1 is fitted at the other end of an adjacent exterior plate. 2 is formed, and the fitting convex portion 1 is fitted into the fitting concave portion 2 to be connected, and the connecting portion is also made of a metal plate as shown in FIG. Blind rivet a from fireproof connection joint material 3a
It is to be fixed to the fireproof skin materials 5, 5 such as the metal plates of the exterior plates Aa, Aa. The fire-proof connecting joint material 3a is constructed so that the interior of the fire-preventing connecting joint material 3a is prevented from appearing on the outdoor surface and deteriorating the appearance.

[Problems to be solved by the invention] However, as described above, the fireproof joint material 3a is used for the exterior plates Aa, A.
In order to construct on the inner side of a, scaffolding must be built on the indoor side, such indoor scaffolding is required, and rivets and other fastening work are required, which requires a great deal of labor and cost. There were problems such as being disadvantageous.

The present invention has been made in view of such a problem, and the purpose thereof is to eliminate the need for indoor scaffolding scaffolding, avoid rivet stop work, and greatly improve workability. It is in providing that you can.

[Means for Solving the Problems] In the fireproof connection structure for an exterior plate of the present invention, a fitting projection 1 is formed on one end of the exterior plate that is fireproof, and the other side end of the adjacent exterior plate is formed. A fireproof connection structure for an exterior plate, in which a fitting concave portion 2 into which the fitting convex portion 1 is fitted is formed, and the fitting convex portion 1 and the fitting concave portion 2 are fitted in a concavo-convex manner. The fireproof connection joint material 3 is formed in a shape along the fitting edge in the fitted state of the fitting convex portion 1 and the fitting concave portion 2, and both exteriors of the fireproof connection joint material 3 in the connected state from the end of the indoor gutter. The connection of the plates is characterized in that both end cover portions 4 for covering the inner surface of the end room are extended.

[Operation] As described above, the fireproof connection joint material 3 made of a metal plate is formed in a shape along the fitting edge in the fitted state of the fitting convex portion 1 and the fitting concave portion 2, and the fireproof connection joint material 3 is formed. In the state where the fitting convex portion 1 and the fitting concave portion 2 are fitted to each other, the both end cover portions 4 that cover the inner surfaces of the connection end portions of the connecting exterior plates of the indoor gutter end portion in the above state are extended. By inserting the fireproof joint material 3 formed in a shape along the fitting edge into the fitting convex portion 1 or the fitting concave portion 2, attachment of the fireproof joint material 3 by rivets or the like is avoided, and therefore, No scaffolding is required, but on the indoor waving surface, the interior plate of the fireproof joint material 3 is connected to the exterior plate A, A which is connected by the both end cover 4 extending from the end of the wa It covers the indoor surface of the so as to obtain sufficient fire protection.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

The exterior plate A is made of fireproof material by surrounding the front and back surfaces of a foamed synthetic resin body 6 such as hard urethane with a fireproof skin material 5 made of a metal plate. The fitting protrusion 1 is formed at one end of the exterior plate A, and the fitting recess 2 into which the fitting protrusion 1 is fitted is formed at the other end. In such a fitting convex portion 1 and a fitting concave portion 2, the front end portion of the fireproof skin material 5 is embedded in the foamed synthetic resin body 6 in a folded shape. The design and shape of the exterior plate A can be changed in various ways.

The fireproof joint material 3 is made of a metal plate, and its shape is formed along the fitting edge in the fitted state of the fitting convex portion 1 and the fitting concave portion 2. That is, the outer curved portion 7 is formed along the outer surface of the fitting convex portion 1 or the inner surface of the fitting concave portion 2,
This is followed by the formation of an inwardly bent portion 9 that can fit into the projection 8 of the fitting recess 2 and the interior of the fireproof joint material 3 is connected from the end of the fitting. Both end cover portions 4 are formed to extend so as to cover the inner surface of the connection end of the plate. Such a fireproof joint material 3 is formed by bending a single metal plate.

As described above, the fireproof connection joint material 3 made of a metal plate is formed in a shape along the fitting edge in the fitted state of the fitting convex portion 1 and the fitting concave portion 2, and the fireproof connection joint material 3 has an indoor end. By extending the both end cover portions 4 that cover the inner surface of the end wall chamber of the connection state of both exterior plates in the connected state, the fitting convex portion 1 and the fitting concave portion 2 are fitted along the fitting edge in the fitted state. By inserting the fire-proof connecting joint material 3 formed in a shape into the fitting convex portion 1 or the fitting concave portion 2, attachment of the fire-proof connecting joint material 3 by rivets or the like can be avoided, and a scaffolding therefor is also required. It is unnecessary, but on the indoor surface, the connection points of the exterior plates A, A in the connected state by the both end cover portions 4 extending from the ends of the indoor part of the fireproof joint material 3 It covers the indoor surface of and obtains sufficient fire protection. And
As shown in FIG. 2, packings 10 and 10 are respectively inserted into the fitting convex portion 1 and the fitting concave portion 2 to ensure water tightness.
The packing 10 may be attached to the fireproof joint material 3 side. The exterior plate A is fixed to the vertical support member 11 from the outside by self-drilling screws 12.

[Effects of the Invention] In summary, the present invention provides a fire-proof connection joint material, which is formed of a metal plate such that the fire-proof connection joint material is formed along the fitting edge in the fitted state of the fitting protrusion and the fitting recess. Since the both end cover portions that cover the inner surface of the connecting end plate in the connected state from the end portion of the indoor gutter in the above state extend along the fitting edge in the fitted state of the fitting convex portion and the fitting concave portion. By inserting the fireproof connection joint material formed in the shape into the fitting convex part or the fitting recessed part, it is possible to avoid attaching the fireproof connection joint material by rivets etc. and to eliminate the need for a scaffolding. However, on the indoor side, the indoor side of the fireproof joint material is covered with the both end cover parts extending from the ends of the fireproof joint to cover the indoor side of the connection part of the exterior plate in the connected state to provide sufficient fireproofing. There is an advantage that it can be obtained.
