Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an exterior panel using lightweight mortar.

(Conventional Examples and Problems) Conventionally, among various methods for finishing the outer walls of buildings such as houses, mortar painting has been relatively often used.

In this case, the construction method is to lay a base material such as pierced or small material on the pillars and studs, affix waterproof paper on top of it, and then stretch wire lath etc. on top of it.
It was common practice to apply mortar coating.
However, all of this type of work was done on-site, which required a lot of manpower, and because the mortar needed to be cured, it took a long time to finish.

In recent years, a so-called drywall structure has been adopted in which a metal or inorganic siding material is pasted on the surface of the base material, but this structure requires curing after finishing. Although it has the advantage of being easy to apply, it has the disadvantage of being very time-consuming to attach.

Furthermore, in these sanding materials,
When used as an exterior material, the strength and quality of the material are inferior, and the construction period has not been significantly shortened.

(Purpose of the invention) In order to solve the above problems, the present invention improves workability on site, and has the strength as an exterior material.
The purpose is to provide exterior panels with excellent quality.

(Structure of the invention) In order to achieve the above object, the exterior panel of the present invention consists of a panel frame made of frame materials, and an exterior surface material made by laminating a waterproof layer and a lightweight mortar finish layer on plywood. It is characterized by being a sanding material that completes the base layer and finishing layer all at once.

Furthermore, the lightweight mortar finishing layer is composed of cement mortar, foamed synthetic resin particles, etc., making the panel itself lightweight and easy to process.

(Embodiments of the invention) Hereinafter, embodiments of the invention will be described based on the drawings.

FIG. 1 is a schematic perspective view of the exterior panel 1. FIG.

Moreover, FIG. 2 is a longitudinal sectional view of FIG. 1.

The exterior panel 1 has an exterior surface material 20 on a panel frame 10.
It is pasted. This exterior facing material 20 includes a waterproof layer 22 and a lightweight mortar finishing layer 23 on plywood 21.
It consists of a stacked structure and is integrally formed.

The panel frame 10 is a frame material 11,1 made of a long material.
1, 11, and 11 are assembled into a rectangular shape, and constitute the skeleton of the exterior panel 1. On the other hand, the exterior surface material 20 is a skin material adhered to this frame.

The waterproof layer 22 constituting the exterior surface material 20 is selected to be waterproof and have good adhesive properties. For example, synthetic resins such as butyl rubber and rubberized asphalt are suitable, and are formed on the surface of the plywood 21 with an appropriate thickness. The lightweight mortar finish layer 23 formed on the upper surface of the waterproof layer 22 is formed by kneading foamed synthetic resin particles such as polyethylene, polystyrene, polyurethane, etc. with a high expansion ratio into cement mortar. The mixing ratio of the cement mortar and the foamed synthetic resin particles is adjusted as appropriate depending on the coating thickness and other finishing conditions.

Furthermore, the particle size of the foamed synthetic resin particles is selected and formed in relation to the above-mentioned mixing ratio, and a material that is a suitable mixture of large and small particle sizes is good in terms of material.

Such a lightweight mortar finishing layer 23 is applied to a coating thickness as required, and decorative grooves 24a,
24b... is processed.

Next, the manufacturing process for the exterior panel having the above structure will be explained.

First, the frame members 11, 11, 11, 11 are assembled into a rectangular shape to form the panel frame 10. Adhesive is applied to one end surface of the panel frame 10, and a plurality of exterior facing materials 20a, 20b, 20c, which have been formed in advance approximately according to the width of the panel frame 10, are attached to the panel frame 10.
Lay and attach it to one side of the 0.

Incidentally, decorative grooves 24a, 24b, . . . are formed in advance at required intervals on the surfaces of the exterior facing materials 20a, 20b, . . . using a mold roll or the like.

Next, after press curing the adhesive surface, the width and length directions of the exterior panel 1 are cut with a sizer to achieve a predetermined dimensional accuracy. Furthermore, the exterior surface material 20a,
The joint joints 25, 25 of 20b, 20c are filled with caulking material, and the required exterior panel 1 is completed through a finishing coating process such as spraying.

When such an exterior panel 1 is assembled as a building wall, the joints between the panels may be processed in the same manner as the joining process for conventional wood-based wall panels.

In addition, when attaching sash etc. in advance, after finishing the exterior panel 1 to the specified dimensional accuracy,
An opening is formed according to the dimensions of the sash frame, the sash frame is attached, and treatments such as caulking are performed.

The exterior panel 1 manufactured in this way has extremely high strength and rigidity as the panel frame 10, which is the skeleton, and the exterior panel material 20, which is the skin material, are integrated, so it can be used as it is as a structural frame of a building. After assembling the exterior panel 1, the wall can be completed by simply applying an interior finishing material such as wall cloth to the interior wall surface. Furthermore, it has multiple functions as an exterior material, such as being waterproof, lightweight, and decorative.

In the above embodiment, three exterior panels were attached to one panel frame, but it goes without saying that one panel may be attached depending on the dimensions of the panel in accordance with the plywood standard.

(Effects of the invention) As described above, the exterior panel of the invention not only has good quality and precision, but also is lightweight and strong.
It is suitable as an exterior material that functions as a base structure.

Furthermore, since it can be manufactured in advance as a building component in a factory, the number of construction works on site is reduced, thereby improving workability and shortening the construction period.

Furthermore, since it is suitable for mass production, the manufacturing cost is low, making it highly industrially viable.
