Description

[Detailed Description of the Invention] The present invention relates to architectural panels, and particularly to improvements in wooden architectural panels.

Conventionally, when finishing the exterior walls of houses, etc., especially when applying mortar coating, the exterior walls are first treated with water resistance (waterproofing), then a mortar base layer such as metal lath is formed, and then mortar is applied. Various operations were required, such as applying an undercoat and then applying a topcoat. Therefore, it usually takes 3 to 4 weeks to form an outer wall on-site, including drying time for mortar and the like. Therefore, for prefabricated houses that particularly require simple and quick work at the construction site, it is best to complete all construction work, including waterproofing on the architectural panels used as exterior walls, at the factory production stage as much as possible. Attempts are being made to reduce each construction work as much as possible. In addition, in some cases, it is not always possible to expect consistent high quality in on-site work, and furthermore, in order to reduce construction costs,
It is desirable to reduce work at construction sites as much as possible.

However, when performing all necessary construction work up to the finishing layer on architectural panels at the factory production stage, there is a risk that the panel surface may be damaged during the transportation process, or it may be damaged due to vibrations, etc. In addition, when assembling panels, the more complete the panels, the heavier and bulkier they are, making it impossible to assemble them by hand, which makes work at construction sites more difficult. There were also drawbacks, such as the fact that panels with a high degree of perfection had to be handled with particular care.

The purpose of this invention is to provide a construction panel that is easy to work on at construction sites, is difficult to damage or break during transportation, is easy to handle, and has excellent functionality as an exterior wall. be.

Therefore, the present invention has a water-resistant layer made of a water-resistant material such as synthetic rubber latex, a fire-resistant layer made of mortar mixed with lightweight aggregate or air bubbles, and a mortar base layer made of polymer cement on the face material of the panel base material. and are each made to have a substantially constant thickness over the entire surface, and are sequentially laminated in the factory production stage according to the stated order, and each layer provides excellent functionality as an exterior wall of a building such as water resistance and fire resistance. The mortar base layer protects the fireproof layer and each layer inside the fireproof layer to effectively prevent damage during the transportation process of the panel, and at construction sites, mortar coating, etc. is applied to the mortar base layer after panel assembly. The objective is to achieve the above objective by making it possible to easily complete the exterior wall of a building.

Hereinafter, embodiments of the present invention will be described based on the drawings.

1 and 2 show a first embodiment of a construction panel according to the present invention. In the figure, a panel core material 1 made of square members assembled into a rectangular frame shape has panel materials 2 pasted on both sides, respectively, thereby forming a panel base material 3.

The facing material 2 is a wood-based plate-like body, such as plywood, fiberboard, honeycomb core plywood, etc., and the space between the facing materials 2 is filled with a heat insulating material (not shown), etc., if necessary.

A water-resistant layer 4 made of a water-resistant (waterproof) substance is laminated on the face material 2, and a fire-resistant layer 5 made of mortar mixed with lightweight aggregate or air bubbles is laminated further above the water-resistant layer 4. . Further, the face material 2 on which the water-resistant layer 4 and the fire-resistant layer 5 are laminated is formed in advance into a plate-like piece such as a rectangular plate having a predetermined size, and a plurality of these face materials 2 are combined to form the core material 1. It is attached to the panel with staples or nails 6, etc., and one side of the panel is constituted by this. In addition, joints 5A formed when a plurality of face materials 2 are brought together (see Fig. 2)
The joints are treated with a joint material 8 of urethane type, silicone type, butyl type, etc.

The water-resistant layer 4 is a thin film, and is water-resistant (waterproof).
It has excellent properties and functions as an adhesive layer with the fireproof layer 5. Water resistant (waterproof) forming this water resistant layer 4
Various substances are selected depending on the purpose and location of the panel base material 3, and its adhesion to the fireproof layer 5, especially the mortar (cement) that constitutes the fireproof layer 5. The coating resins used are, more specifically, synthetic rubber latexes, bituminous emulsions, and the like.

The fireproof layer 5 is made of lightweight aggregate or mortar mixed with air bubbles, and as the cement in the mortar, Portland cement or the like is used. Synthetic resin particles, perlite, vermiculite, etc. are used as lightweight aggregates, and when fire resistance or heat insulation performance is particularly desired, foamed synthetic resin particles with a closed cell structure are used. Further, when air bubbles are mixed into the mortar, the fireproof layer 5 becomes so-called lightweight cellular concrete, but when foamed synthetic resin particles are mixed, it can also be said to be a type of lightweight cellular concrete.

The refractory layer 5 having such a structure is extremely lightweight with a specific gravity of about 0.5 to 1.0, and is easy to cut, nail, etc., and has excellent workability. The thickness of the fireproof layer 5 is usually about 5 to 15 mm, and is selected depending mainly on the type of finishing coating and the desired fireproof performance. Even when the fireproof layer 5 is thick, the fireproof layer 5 is given high adhesiveness to the face material 2 by the adhesive force of the waterproof layer 4.

Although the refractory layer 5 is relatively brittle, a mortar base layer 7 made of polymer cement is laminated on top of the refractory layer 5, and this mortar base layer 7 makes the refractory layer 5
The surface of the panel is protected, and high adhesion between the fireproof layer 5 and the mortar layer applied after panel assembly is provided.

The polymer cement that forms the mortar base layer 7 is mainly composed of special cement, hard aggregate, and special flat fine powder.The special cement provides water resistance and high strength, and the hard aggregate provides high strength and wear resistance. The special flat fine powder provides water permeability,
Provides shrinkage stress relaxation and crack resistance. The polymer cement mixture is an acrylic or other special synthetic resin emulsion, and this emulsion provides high adhesive strength, high water resistance (waterproofing), and high gas permeability. By mixing the mixed liquid 1 with such a main material 3 and further adding a small amount of fresh water, a neutralization prevention function, a waterproof function, a high adhesive strength, or a rust prevention function can be imparted to the mortar base layer 7. becomes.

The polymer cement may be made of special synthetic fibers as a main material instead of the special flat fine powder. If special synthetic fibers are used, trowel workability will be provided in addition to the above-mentioned performance.

This mortar base layer 7 protects the fireproof layer 5 and the waterproof layer 4, and the mortar base layer 7 itself has excellent water resistance (waterproofing), and together with the waterproof layer 4, it functions as double waterproofing. In addition, the base layer 7
Packaging the fireproof layer 5 together with the waterproof layer 4, it serves to maintain the fireproof performance of the fireproof layer 5, and also has excellent rust prevention performance against nails 6 and the like.

Further above the mortar base layer 7, a mortar coating is applied as a finishing coating, and the mortar finishing layer may be a normal trowel coating, or a mortar coating in which the mortar is sprayed with a spray gun and the sprayed surface is leveled with a trowel. A stucco finish or the like may be used. Note that what is laminated on the mortar base layer 7 is not limited to such a mortar finish layer, but may be another finish layer, such as a drywall finish or a tile finish.

When the finish applied to the base layer 7 is other than drywall finish, the finish layer and the fireproof layer 5 are firmly adhered to each other by the high adhesive strength of the mortar base layer 7, and the fireproof layer 5 is attached to the face material 2 with water resistance. It is bonded with a high adhesive force by layer 4, and therefore each layer on the facing material 2, including the finishing layer, is extremely strong. On the other hand, when finishing drywall, the nails, screws, etc. used to nail and fix the drywall onto the base layer 7 can easily penetrate through each layer 4, 5, and 7, making it easier to nail the drywall. ing.

According to this embodiment, the water-resistant layer 4 provides excellent water resistance (waterproofing), and the lightweight and inexpensive fire-resistant layer 5 provides excellent fire resistance. As for No. 3, although it is made of wood, it has excellent performance as an outer wall of a building.

Furthermore, the mortar base layer 7 made of polymer cement has the effect of further improving the water resistance and fire resistance of the outer wall. Furthermore, this mortar base layer 7 provides extremely strong adhesion between the fireproof layer 5 and the mortar finish layer etc. that is finished after assembly, resulting in a solid outer wall.
Furthermore, since the adhesion is improved in this way,
It is also easier to paint a thick layer of mortar,
Workability is also improved.

In addition, since the mortar base layer 7 has sufficient strength to protect the fireproof layer 5 and water-resistant layer 4 below the mortar base layer 7, the fire-resistant layer 5 and water-resistant layer 4 may be damaged during panel transportation or panel assembly. This has the effect that there is no risk of damage or the like and therefore ease of handling.

Further, since the mortar base layer 7 is produced in advance at the factory stage, the work at the construction site is extremely simple, and the quality and accuracy are also stable. Furthermore, since the mortar base layer 7 is uniformly machined in advance at the factory stage, it can be provided at low cost.

Furthermore, since the mortar finishing layer is applied on top of the mortar base layer 7 after assembly, it is extremely light when shipped from the factory with the mortar base layer 7 laminated, and from this point of view it is also easy to handle. , and easy to assemble.

Furthermore, since the thickness of the water-resistant layer 4 and the fire-resistant layer 5 are approximately constant over the entire surface, the bonding area between the two is widened, and the adhesion state is good. Installation work becomes easier.

In addition, since the face material 2 of a predetermined shape (size) on which the water-resistant layer 4 and the fire-resistant layer 5 are laminated in advance can be manufactured by nailing it onto the core material 1 with nails 6 or the like, productivity in the factory can be improved. It has an extremely high effect.

Next, embodiments other than those described above will be described, and the same reference numerals will be used for parts that are the same as or similar to those of the embodiments described above, and the explanation will be omitted or simplified.

A second embodiment is shown in FIG. In the second embodiment, the facing material 2 on which the water-resistant layer 4 and the fire-resistant layer 5 are laminated in advance is not nailed onto the core material 1, but after the facing material 2 is attached onto the core material 1, Each layer 4, 5, 7 is sequentially applied on this face material 2. Even in such a second embodiment, substantially the same functions and effects as those of the first embodiment can be achieved.

A third embodiment is shown in FIG. In the third embodiment, in order to particularly completely protect the exposed peripheral portion of the fireproof layer 5, the exposed peripheral portion of the fireproof layer 5 is protected by the water-resistant layer 4. According to the third embodiment, damage to the fireproof layer 5 during the transportation process and assembly can be more completely prevented than in the first and second embodiments, and when the panels are jointed, Continuous water resistance (waterproofing) through caulking, etc.
This has the effect of providing layers. Note that the exposed peripheral portion may be protected by a mortar base layer 7.

A fourth embodiment is shown in FIG. In this fourth embodiment, a plate-like body 11 of a predetermined size is prepared, a water-resistant layer 4 and a fire-resistant layer 5 are laminated on this plate-like body 11, and then the plate-like body 11 is attached to a panel base with nails 6. After that, a mortar base layer 7 is laminated on the refractory layer 5 so as to cover the heads of the nails 6. According to the fourth embodiment, although the layers 4, 5, and 7 are not directly laminated on the surface material 2, substantially the same functions and effects as in the first to third embodiments can be achieved. can.

As described above, the present invention provides a construction panel that is easy to work at a construction site, is less likely to be damaged or broken during the transportation process, is easy to handle, and has an excellent function as an exterior wall. can do.
