Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an exterior panel, and more specifically,
For example, it relates to improvement of a non-combustible exterior panel attached to the outer surface of a building frame.

[Prior Art] Generally, as this type of exterior panel, for example, one aluminum alloy panel or a chrome-plated steel plate is used, and these exterior panels are fixed to the exterior surface of the outer wall of the building. It is mounted so as to cover the entire area of the building through a mounting means composed of an angle piece and a furring strip fixed to the angle piece.

[Problems to be solved by the invention] However, since the conventional exterior panel of this type is a single metal plate made of aluminum alloy or the like, heat from the outside is easily transferred to the body, and a sufficient heat insulating effect is obtained. There is a problem that the exterior panel cannot be exhibited, and the exterior panel may melt and disappear in the event of a fire. There was also the problem of causing a physical disaster.

Therefore, under the present circumstances, there is a demand for the development of an exterior panel which is rich in heat insulation and fire resistance and which does not fall off even in the event of a fire.

[Means for Solving the Problems] The present invention has been made in view of the above circumstances, and in order to solve the above-mentioned technical problems, an exterior panel attached to an outer surface of a building body through attachment means is provided. A packing for filling a heat-insulating core material containing an inorganic heat-insulating material between a pair of non-combustible surface plates, and for holding at least the outer side surface and the end surface of the heat-insulating core material on at least two opposite sides of the heat-insulating core material. It is intended to provide an exterior panel characterized by mounting a reinforcing member having a holding portion and an outwardly mounting flange portion.

In this invention, the surface plate may be made of any non-combustible material, but is preferably non-combustible and strong like an aluminum alloy or steel plate surface plate. Better. The heat insulating core may be any as long as it contains an inorganic heat insulating material, for example, the core may be formed only of the inorganic heat insulating material, or at least one surface of the inorganic heat insulating material. A cushioning material may be interposed between the two. In this case, the inorganic heat insulating material is formed by molding a reaction mixture containing a granular inorganic foam, an alkali silicate solution used as a binder, and a curing agent mainly composed of metal silicon powder, A known one may be used. In this case, the inorganic foam used for producing the inorganic heat insulating material is, for example, obsidian, vermiculite, pearlite, pine rock, etc., and the particle size and density are usually 0.5 to 7 mm. Diameter and a density of 0.1 to 0.25 g / cm ³ in general, and a density of 0.
1 to 0.16 g / cm ³ is used. Further, the alkaline silicate solution used as the binder is usually an aqueous sodium silicate solution or an aqueous potassium silicate solution, and is preferably an aqueous sodium silicate solution in terms of solubility in water and raw material cost. As sodium,
The molar ratio of SiO ₂ and Na ₂ O is usually 2.0 to 3.5, preferably 2.3 to 2.7, and the concentration of the aqueous solution is usually 35 to 42% by weight, preferably 40 to 42. % By weight, and the amount used is 100% of the inorganic foam.
It is usually 30 to 120 parts by weight, preferably 50 to 100 parts by weight, based on parts by weight. Further, as the binder curing agent, for example, metal silicon, ferrosilicon which is an alloy of iron and silicon, a mixture of metal silicon and silicon dioxide, or the like, or a metal silicon powder having the properties of metal silicon, alone or in combination of two or more. Can be used as a mixture, preferably in combination with various phosphates such as condensed phosphate metal salts represented by condensed aluminum phosphate as other components of the curing agent for the purpose of improving the compressive strength and water resistance, The amount of the curing agent used varies depending on the type and concentration of the alkali silicate solution, but is usually 10 parts with respect to 100 parts by weight of the alkali silicate solution.
-20 parts by weight, preferably 13-15 parts by weight. In addition, in the inorganic heat insulating material used as the core material, if necessary, for example, steel fiber, glass fiber, and a reinforcing additive such as rock wool are mixed, and mechanical strength of the exterior panel produced, for example, tensile strength, etc. Can be improved.

Further, the reinforcing material may be of any form as long as it has a holding portion that holds at least the outer side surface and the end surface of the heat insulating core material and an outward flange portion, for example, heat insulation. A holding portion that holds the outer side surface and the end surface of the sex heartwood,
An approximately crank-shaped cross section having an outward flange portion that extends outward from one end of the holding portion, or
The holding portion may be formed to have a substantially U-shaped cross section, and further, it is preferable that the holding portion is formed with a reinforcing protrusion protruding toward the inside of the heat insulating core material. . In this case, it is preferable to install the reinforcing material so as to be embedded between the heat insulating core material and the surface plate. In addition, the outward flange portion of the reinforcing member can be directly fixed to the attachment means fixed to the outdoor surface of the building frame by the fixing member, or
It can also be fixed to the attachment means by using a separate fixing member.

The method of manufacturing the exterior panel configured as described above is not particularly limited, but usually, each member formed in a predetermined shape and size, that is, an inorganic heat insulating material serving as a core material, a surface plate and a reinforcement The material is attached using an adhesive, preferably an epoxy adhesive, or a surface plate coated with urethane adhesive is incorporated into the mold as needed. Manufactured by a method such as a method for forming a granular inorganic foam, a reaction mixture containing an alkaline silicate solution used as a binder and a curing agent mainly composed of metal silicon powder to form an inorganic heat insulating material as a core material can do.

[Operation] The above technical means operates as follows.

As described above, the heat-insulating core material containing the inorganic heat-insulating material is filled between the pair of non-combustible surface plates, and at least two opposite sides of the heat-insulating core material are provided with at least an outer surface and an end surface of the heat-insulating core material. By attaching a holding member to be held and a reinforcing member having an outward mounting flange portion, the nonflammable performance of the surface plate and the heat insulating function of the heat insulating core material are combined to form a fire resistant exterior portion. In addition, even if the surface plate melts and disappears in the event of a fire, the reinforcing material can prevent the heat insulating core material from falling off.
