However, Reference Documents 1 to 3 generally have a structure using a wall panel made of an inorganic material such as an ALC board, a PC board, an extruded cement board, a calcium silicate board, and a gypsum board as a wall panel, and a metal. Wall panels with a core material made of synthetic resin foam sandwiched between a surface material made of metal and a back material made of metal were rarely used due to the problem of fire resistance.

In order to solve such a drawback, the present invention has a metal in a synthetic fireproof structure using a synthetic fireproof joiner in which fireproof blankets are formed at both ends of a metal floor joint formed on the back surface of a vertical joint of a horizontal wall panel. The floor joint is a flat support part, a step where both ends of the support part are inclined and hung in a direction away from the wall panel , a protruding piece with the tip of the step extended outward, and the tip of the protruding piece. Is formed from a locking piece bent toward the step side and a locking groove formed from the locking piece and the protruding piece, and the fire protection blanket is hung from the locking groove to the locking piece to the protruding piece to form a metal joint. It provides a synthetic fireproof joint structure characterized by being integrated with a plate.

According to the synthetic fire-resistant joint structure according to the present invention, (1) no gap due to thermal deformation is generated between the wall panel and the fixed base during the fire resistance test, and the fire resistance performance is improved. (2) A structure having a performance that passes a fireproof structure test of a synthetically coated fireproof structure using a wall panel in which a core material made of a synthetic resin foam is sandwiched between a metal front material and a metal back material can be obtained. There are features and effects such as.

A typical example of the synthetic refractory joint structure according to the present invention will be described in detail below with reference to the drawings. 1 to 3 are cross-sectional views showing a construction state of the synthetic refractory joiner A, and FIG. 4 is a perspective view showing a construction state of the synthetic refractory joiner A. FIG. 5 is a cross-sectional view showing a synthetic fireproof jointer A used for the synthetic fireproof joint structure according to the present invention, in which 1 is a metal floor plate and 2 is a fireproof blanket. FIG. 6 is a cross-sectional view showing a metal floor plate 1 which is a member of the synthetic refractory joiner A.

As shown in FIGS. 1 to 4, in the synthetic coated fireproof structure in which the square steel pipe in the vertical joint portion M is formed as a base material, the square steel pipe connecting portion α is the fireproof coating material α2 such as square steel pipe column α1 and rock wool. , It is formed from the fixture α3. Further, β is a fixed base and γ is a fixture.

The synthetic fireproof joiner A is a long member having a cross section as shown in FIG. 5, and is formed of a metal floor plate 1 and a fireproof blanket 2.

Further, as shown in FIG. 6, the metal floor plate 1 has a flat support portion 3, a step 3a in which both ends of the support portion 3 are inclined downward and hangs down, and the tip of the step 3a is outward. Formed from a protruding piece 4 extended to the surface, a locking piece 5 having the tip of the protruding piece 4 bent inward, a locking groove 6 formed from the locking piece 5 and the protruding piece 4, and a support space 7. Is.

As shown in the figure, the support space 7 formed by the step 3 is formed in a shape that matches the fixed base β , thereby preventing the synthetic fire resistance joiner A from rattling and forming a gap during the fire resistance test, and has fire resistance. It contributes to improvement.

The projecting piece 4, the locking piece 5, and the locking groove 6 are portions for securely fixing and adhering the fireproof blanket 2, and prevent a gap from being formed between the back surface of the wall panel P and the fixed base β to improve fire resistance. It will improve.

As shown in FIGS. 7 to 9, the wall panel P is an L-shaped joint piece P1 in which the ends of the metal surface material P5, which are both ends when the wall panel P is constructed in a horizontal shape, are bent into an L shape.
