Description

[Detailed Description of the Invention] This invention relates to a composite fireproof panel comprising a fireproof panel made of a fireproof material and a covering panel covering the same.

Fireproof panels such as lightweight aerated concrete boards, asbestos cement calcium silicate boards, and asbestos cement boards are often used for the exterior walls of buildings because of their excellent durability, fire resistance, and heat insulation properties. However, the above-mentioned fireproof panels have disadvantages in that they are brittle and easily damaged during construction, especially at the corners, and are highly water-absorbing, allowing water to pass through, and lack color, which makes them difficult to match with surrounding buildings. Therefore, as shown in FIG. 1, a composite fireproof panel 33 has been proposed in which a flat aluminum plate 32 is bonded to the surface of a fireproof panel 31 with an adhesive. The fireproof panel 31 has a groove 34 on its side surface, and as shown in FIG. 2, reinforcing bars 35 are passed through the grooves 34 of the adjacent composite fireproof panel 33 when constructing the wall of a building, and then concrete mortar M is inserted. The concrete mortar M is filled with the composite fireproof panel 33 to connect them together, but at this time it is necessary to fit joint bars (boards) into the gaps 36 and 37 to prevent the concrete mortar M from flowing out to the back and front sides of the composite fireproof panel 33. The work was complicated. In addition, the gap 37 on the front side of the composite fireproof panel 33 is filled with caulking material C to seal it and prevent rainwater from entering from the outside. In order to make the dimensions uniform over the entire length of the panel, it is necessary to make troublesome adjustments to the mounting position of the composite fireproof panel 33.
Furthermore, since the adhesive surface of the aluminum plate 32 has an extremely shallow sealing depth, rainwater easily enters the adhesive surface, and since the aluminum plate 32 is only held by a flat joint surface, the aluminum plate 32 may peel off and fall. It had the disadvantage of being easy to do.

This idea solves the above-mentioned conventional drawbacks.
By firmly covering the front side of a fireproof panel with a coating panel such as an enamel panel, we can take advantage of the features of the fireproof panel while eliminating its flaws such as brittleness and water permeability. It is an object of the present invention to provide a useful composite fire-resistant panel that has excellent weather resistance and a variety of colors. Furthermore, this invention aims to provide a composite fire-resistant panel that can reliably integrate a covering panel and a fire-resistant panel with a simple structure and that can be easily installed on the walls of buildings.

Therefore, the gist of the present invention is to cover and fix a covering panel having a main plate part facing the surface of the fireproof panel and a bent piece part facing the side surface of the fireproof panel to the fireproof panel. A groove for filling a binder extending in the longitudinal direction of the side surface is provided on the side surface of the fireproof panel, and the top of the side wall portion formed on the back side of the fireproof panel of the groove is formed on the front side of the fireproof panel of the groove. The composite fireproof panel is characterized in that it protrudes laterally beyond the surface of the bent piece covering the side wall.

As the fireproof panel in this invention, lightweight aerated concrete board, asbestos cement calcium silicate board, asbestos cement board, PC board, gypsum board, glass fiber reinforced gypsum board, etc. are used. Further, as the coated panel in the present invention, a copper plate, a stainless steel plate, a colored iron plate, an aluminum plate, an enameled aluminum plate, an enameled iron plate, an enameled aluminum plated steel plate, a synthetic resin-coated steel plate, a synthetic resin plate, etc. are used.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

Fireproof panel 1 made of lightweight aerated concrete board
A semicircular groove 3 extending in the longitudinal direction of the side surface is provided in the side surface 2a of the side surface 2a. As shown in the fourth figure, the side wall portion 5 on the back side of the fireproof panel is larger than the side wall portion 4 on the front side 6 of the fireproof panel. Covering panel 7 consisting of an enamel panel with enamel processing applied to both sides of a steel plate
The fireproof panel 1 has a main plate part 8 facing the surface 6 of the fireproof panel 1 and a bent piece part 9 facing the side surface 2a and end face 2b of the fireproof panel 1, and has a panel width narrower than the fireproof panel 1. surface 6 and side 2
It is placed over the fireproof panel 1 so as to cover part of the end face 2b and the end face 2b, and is fixed to the fireproof panel 1 by driving a nail 10 through the bent piece 9 into the fireproof panel 1. Note that instead of fixing with nails 10 (or in combination), an adhesive interposed between surface 6 of fireproof panel 1 and main plate 8 of covering panel 7 may be used to fix them together. In this fixed state, the top of the side wall 5 of the fireproof panel 1 projects laterally beyond the surface of the bent piece 9 that covers the side wall 4 of the covering panel 7.

In order to construct a wall surface of a building using composite fireproof panels 11 having the above configuration, adjacent composite fireproof panels 11
abutting the top surfaces 5a of the side wall portions 5 against each other, inserting a joint bar only between the bent pieces 9, 9 on the front side of the panel,
After a reinforcing bar 13 connected to a building frame is inserted into a substantially cylindrical space 12 formed by the grooves 3, 3, a binder M such as concrete mortar or white cement is filled and solidified. After the binder hardens, the gap 14 between the bent pieces 9 and 9 on the panel surface side
What is necessary is to fill the caulking material C to form joints. In this way, a uniform joint width can be obtained simply by butting the side surfaces of adjacent composite fireproof panels 11, and there is no need to use a joint rod when filling the binder, so construction can be carried out quickly and easily. In addition, if a thick caulking backer is press-fitted between the bent pieces 9 and 9 on the front side of the panel and then filled with the binder M, there is no need to attach or remove the joint rod to the front side of the panel, making the construction even easier. It becomes easier.

FIG. 5 shows another embodiment of this invention, which differs from the previous embodiment only in that a connecting piece 21 is used to attach the covering panel 7 to the fireproof panel 1. The connecting piece 21 has a curved part 22 that fits into the groove 3, and is connected and fixed to the fireproof panel 1 with a nail 23 passing through this curved part 22. It is connected to part 9. The composite fireproof panel having this structure also provides the same effects as those of the embodiments described above.

This invention is not limited to the above-mentioned embodiments, and, for example, the attachment of the covering panel to the fireproof panel may have a structure other than that described above. Further, the shape of the groove provided on the side surface of the fireproof panel may be a trapezoid, a square, a V-shape, etc. other than a semicircle. Further, in each of the above embodiments, a covering panel having bent pieces facing the side surface 2a and end surface 2b of the fireproof panel was used. The present invention can also be applied to a case where a covering panel having only a folded piece facing the side surface 2a of the fireproof panel is used, as in some cases.

As explained above, according to this invention, the disadvantages of fireproof panels such as brittleness and water permeability are eliminated, and the durability and heat insulation properties are taken advantage of, while the excellent features of coated panels such as enamel panels are A composite fireproof panel with weather resistance and a variety of colors can be obtained. In addition, since the folded piece of the covering panel covers a part of the side surface of the fireproof panel, this folded piece can be used to securely connect it to the fireproof panel. The fireproof panel and the covering panel can be reliably integrated with a simple structure. In addition, when constructing walls of buildings, the conventional work of inserting and removing joint rods on the back side of the wall, and measuring and adjusting joint widths is no longer necessary, simplifying construction, saving labor, and shortening the construction period. .
