BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a fireproof panel that constitutes an inner wall. More specifically, even if the decorative surface width and the panel thickness are increased, the male and female fitting structures do not separate from the wall base material, and the panel mounting members such as screws are exposed to the outside. The present invention relates to a fireproof panel that can be stretched vertically and horizontally.

2. Description of the Related Art Heretofore, as this type of panel, a large number of panels having a laminated structure of a surface material, a core material, a back surface material, ceramics such as cement and the like have been put on the market. These panels are roughly classified into a butt structure, an actual perforated structure, a phase determination structure, and a hooking structure. As such, Japanese Patent Laid-Open Nos. 2-279863 and 1-
There is a publication of 290869.

The one disclosed in JP-A-1-290869 is
Since only one edge of the backing material is fixed to the frame, the strength is weak, especially the lower end of the panel is only held by the actual (sane) structure of the upper end of the lower panel in the fitting structure. Therefore, it floats up to a negative pressure and causes not only water leakage but also deformation in a remarkable case.
Further, when the surface material is fixed only by the adhesiveness with the core material, there is a risk that the surface material may come off when a fire or an earthquake occurs.

In the invention disclosed in Japanese Patent Laid-Open No. 2-279863, the surface material is fixed through one end so that the surface material does not come off. However, the lower end of the panel is fixed to the lower panel having a fitting structure. Since it is only held by the actual structure of the upper end of the, the strength is still weak,
Especially for negative pressure, it not only causes floating and water leakage, but also deforms in a remarkable case. Moreover, since the structure is complicated, the manufacturing cost is high, and it is necessary to use a core material that can fill even these small gaps. The core material that can be used in such a case is limited to a synthetic resin foam or the like, which can be filled with a raw material inside, reacted, and foamed, as described in the specification. It is not suitable for the core material.

DISCLOSURE OF THE INVENTION An object of the present invention is to use a thin metal plate material for a front surface material and a back surface material, and to reinforce a U-shape that fits into a slit of two U-shaped portions forming a recess. By interposing the material, it prevents the panel from peeling due to the thermal expansion, contraction of the panel and the deformation of the stud due to the earthquake and the like, and the surface material from peeling off, and also ensures the strength retention when receiving negative wind pressure. Another object of the present invention is to provide a fireproof panel that has passed the fireproof test and can have a large width and thickness on the decorative surface.

[0006]

The present inventors have completed the present invention as a result of intensive studies to solve the above-mentioned problems. That is, the present invention is a construction fireproof panel in which a core material is sandwiched between a surface material and a back surface material made of a thin metal plate material, and a concave portion into which a head of a convex edge of an adjacent panel enters at one end of the panel. In a panel having a convex portion formed at the other end, the concave portion is provided between a front surface material and a rear surface material whose one end is bent inward in a U shape, and two U constituting the concave portion are formed. It is a fireproof panel in which a U-shaped reinforcing material that fits into the slit of the character portion is interposed.

The fireproof panel according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of a fire-resistant panel as a typical example of the present invention.
A fireproof panel having a sandwich structure made of a core material 30. The front surface material 1 and the rear surface material 20 are made of thin metal plate material, and are made of, for example, Al, Fe, Cu, stainless steel, aluminum-zinc alloy plated steel plate, color steel plate, enamel steel plate, fluororesin coated steel plate, clad steel plate, sandwich steel plate, etc. It is formed by press molding, extrusion molding, roll molding, or the like. In the fireproof panel shown in FIG. 1, the decorative surface 2, the female connecting portion 40, and the male connecting portion 50 are formed.

As shown in FIG. 2, this surface material 1 has a decorative surface 2 which forms the surface of the wall body when the wall body is formed, and a projection in which one end side of the decorative surface 2 is projected in a U shape. An engaging portion 5 is formed from the portion 3 and a reinforcing rib 4 in which the return tip of the plate material of the protruding portion 3 protrudes inward perpendicularly to the decorative surface, and the other end of the decorative surface 2 has a decorative surface 2 The thickness of the U-shaped protrusion 3 is slightly larger than the thickness of the U-shaped protrusion 3 so that it does not come into contact with the protrusion 3 of the adjacent panel, and is slightly longer than the length of the U-shaped protrusion 3. The bent portion 6 and the recessed portion 7 into which the head of a mounting member such as a screw is inserted, and the portion 8 parallel to the decorative surface are provided, and the tip thereof is projected inwardly perpendicular to the decorative surface. It consists of a plug-in fixing part 10 consisting of a reinforcing rib 9. The surface material 1 is composed of a decorative surface 2, an engaging portion 5, and an insertion fixing portion 10.

As shown in FIG. 3, the back surface material 20 is formed by projecting one end of a plate material made of one of the above materials into a U-shape that is shorter than the U-shaped projection 3 of the surface material 1. And the return tip of the plate material of the protruding portion 21 is projected inward in a direction perpendicular to the back surface material 20 to form a reinforcing rib 22, thereby forming a lower edge 23 of the engaging portion. The other end side is bent inward a little more than the thickness of the U-shaped protrusion 21 so as not to contact the protrusion 21 of the adjacent panel, and is slightly longer than the length of the U-shaped protrusion 21. Bent portion 24
And a portion 25 that is parallel to the back surface material, and has a lower edge 27 of the insertion fixing portion that is composed of a reinforcing rib 26 that has its tip protruding inward perpendicularly to the back material. The back surface material 20 includes a back surface material 12, an engaging portion lower edge 23, and an insertion fixing portion lower edge 27.

In this way, the female connecting portion 40 has the U-shaped protruding portion 3 of the engaging portion 5, the reinforcing rib 4, and the lower edge 23 of the engaging portion.
The U-shaped projecting portion 21, the reinforcing ribs 22, and the core member 30 have a substantially U-shaped mating portion whose side cross section is substantially deformed, and the U-shaped reinforcing material 41 is provided in this recess. Part 50 is
The insertion fixing part 10, the lower edge 27 of the insertion fixing part, and the core material 30.

As shown in FIG. 4, the female connecting portion 40 engages with the male connecting portion 50 of the adjacent panel, and when it is fixed to the wall base 60, the male connecting portion 50. The mounting member 70, such as a screw, is inserted through the insertion recess 7 into which the head of the mounting member is inserted and fixed to the wall base 60. Then, the fixed male connection portion 50 is fitted with the female connection portion 40 of the adjacent fire-resistant panel. At this time, in order to improve fire resistance, the reinforcing ribs 4 facing each other and the male mold of the adjacent panel are fitted together. The refractory joint material 80 is preferably sandwiched between the reinforcing ribs 9 of the connecting portion 50 and between the reinforcing ribs 22 and the adjacent reinforcing ribs 26. The fire resistant joint material is not particularly limited, but a joint material made of rock wool or ceramic fiber is preferable.

In order to strengthen the connection between the female connecting portion 40 and the male connecting portion 50 of the adjacent panel, the cross section of the surface material of the engaging portion of the female connecting portion and the U-shaped projection of the rear surface material are cross-sectioned. It is preferable to have a modified U-shaped reinforcing member 41. The U-shaped reinforcing member 41 used here is for strengthening the female and male fitting structure, and prevents deformation of the lower end of the panel against negative pressure and prevents water leakage. .

During transportation and handling of the panel at the time of construction, there is a tendency to handle only the U-shaped projection on one side of the female part, the U-shaped projection surface material or the back surface material, and even in that case, the surface material or the back surface In order not to adversely affect the adhesion between the core material and the core material,
The U-shaped reinforcing member 4 is effective.

As the reinforcing material, any non-combustible and strong material can be used. For example, Al, Fe, Cu, stainless steel, aluminum-zinc plated steel sheet, color steel sheet, enamel steel sheet, fluorine resin coated steel sheet, resin coated steel sheet. Clad steel plates, sandwich steel plates and the like, which are formed by means of press forming, extrusion forming, roll forming, etc., may be used. In particular, the above materials may be punched in order to minimize heat conduction.

The above-mentioned refractory joint material has a U-shaped protruding portion 3 of the surface material 1 forming the female connecting portion 40 when the female connecting portion 40 and the male connecting portion 50 are fitted together. The male connecting portion 50 of the adjacent panel and the U-shaped protruding portion 21 of the back surface member 20 constituting the female connecting portion 40 are formed between the male connecting portion 50 of the adjacent panel and the male fixing portion 50 of the adjacent panel. The area between the back surface material and the parallel portion 25 of the lower edge 27 of the insertion fixing part becomes a passage for hot air, fire, etc. to enter from the surface material 1 side and reduces fire resistance. Mold connection part 40
There is no particular limitation as long as it is a heat-resistant joint material that is sandwiched for preventing a heat bridge between the male type connecting portion 50 and the male joint portion 50, but a joint material made of rock wool or ceramic fiber is preferable. is there. Then, in order to improve workability, it is preferable that the fire-resistant joint material is previously fixed to each reinforcing piece of the female connecting portion 40 or the male connecting portion 50 by using an adhesive or the like.

Since the core material 30 simplifies the structure of the fireproof panel and prevents the cost from increasing, it is not preferable to use the conventional synthetic resin foam, and it is preferable to use rock wool, calcium silicate, gypsum board or the like. It is preferred to use one or more strong, molded refractory members. Further, most of the core material is composed of a lightweight fireproof member such as rock wool, and high strength calcium silicate, gypsum board, etc. are used at the portions contacting the back surfaces of the reinforcing pieces 4, 9 and 22, 26, Higher strength can also be achieved.
