Field of the Invention [0002] The present invention relates to an outer wall structure of a building using a molded board made of foamed plastic and having excellent fire resistance, and foam for the outer wall. The present invention relates to a plastic molded board. [0002] A molded board made of foamed plastic such as polystyrene foam has been conventionally used as an insulating material on the outer wall of a building. By the way, generally, the outer wall of a building is required to have heat insulation and economy, and also to have fire resistance. However, since the above-mentioned foamed plastics generally have a flammable property, they have a drawback that fire resistance is remarkably inferior to other wall materials. In addition, foamed plastics generally lack mechanical strength, have a large shrinkage ratio, have poor shape retention, and have the disadvantages of large aging and lack of durability. Met. [0003] In recent years, the exterior wall of a general building in which an airtight heat insulating material is used has a problem that moisture condenses inside the wall due to a temperature difference and causes mold, corrosion and the like. It is well known. [0004] Therefore, the present invention is to provide a foamed plastic molded board as a heat insulating material, while having excellent fire resistance, durable and without the risk of condensation. The purpose is to provide an outer wall structure of a building that is excellent in heat insulation and economy. [0005] For this purpose, in the outer wall structure of a building according to the present invention, a molded board made of foamed plastic having a groove for arranging reinforcement on its surface is arranged on the surface of a subbing board. While driving the molded board with a screw nail from the surface and fixing it to the surface of the subboard, a ventilation gap is formed between the back surface of the molded board and the surface of the subboard,
A wire mesh is arranged in the reinforcing groove, and mortar is applied to the surface of the molded board.
Further, the present invention is characterized in that, in the outer wall structure, at least a concave portion is formed on the back surface of the molding board in a vertical direction so that a ventilation gap is formed between the outer wall structure and the surface of the underlay plate. I do. Further, the present invention is characterized in that, in the above outer wall structure, the molding board is molded by a bead method polystyrene foam. Further, the present invention is characterized in that, in the outer wall structure, a spherical washer is engaged with the surface of the molded board and a nail is driven into the surface, and a spherical depression is formed on the surface of the molded board by the driving. And Further, in the outer wall structure according to the present invention, the spherical washer may be provided with an engagement hole formed at an eccentric position for driving a screw nail obliquely downward toward the molding board, and the screw nail may be horizontally positioned toward the molding board. And an engagement hole formed at a center position for driving the vehicle. Further, the present invention is characterized in that, in the above outer wall structure, an anchor fitting buried in mortar is fixed in the spherical washer. Further, the present invention is characterized in that in the above outer wall structure, a termite-control sheet is interposed between the back surface of the molded board and the surface of the underlay plate. Further, the foamed plastic molded board for an outer wall according to the present invention is a molded board made of a foamed plastic having a square plate shape, a groove for reinforcement is formed on a surface, and at least a concave portion is formed on a rear surface of the molded board. Is formed. The present invention also relates to the foamed plastic molded board for an outer wall, wherein the molded board is made of a foamed plastic in the form of a square plate, and is formed with ridges and grooves for fitting on four sides. . Further, the present invention is characterized in that the foamed plastic is a beaded polystyrene foam in the foamed plastic molded board for the outer wall. Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 8 show a molded board made of foamed plastic according to the present invention. This molded board 1 is made of EPS
(Expanded Poly-Styrene) That is, it is formed by molding a polystyrene resin by a bead method, is a square plate having a density of about 20 kg / m 3 and a thickness of about 72 mm, and has a reinforcing bar with a depth of about 7 mm on the surface. Grooves 2 are formed vertically and horizontally in a grid shape, and fine irregularities 6 in the shape of a turtle pattern consisting of a concave portion 3, a convex portion 4, and a groove portion 5 are formed on the back surface as shown in an enlarged manner in FIGS. Has formed. This unevenness 6 is shown in FIG.
As shown in the cross-sectional view of FIG. 3, adjacent recesses 3 are formed in a form continuous with each other vertically and horizontally by a groove-like portion 5, which increases the surface area and forms an outer wall as described later. At least a ventilation gap communicating vertically is ensured. As shown in FIGS. 6 to 8, a ridge 7 protrudes from the upper side and the left side of the molded board 1, and a concave groove into which the ridge can fit. 8 are formed. Reference numeral 9 denotes a small groove formed on the surface of the ridge 7 for preventing inundation. Next, the case where the above-mentioned molded board 1 is used for a wooden house by a framed wall method will be described as an example of the outer wall according to the present invention. 9 is a longitudinal sectional view of the outer wall, FIG. 10 is an enlarged view of a main part thereof, and FIG. 11 is a partial sectional perspective view. In the figure, 20 is a concrete foundation, 21 is a wooden column established on the foundation, 22 is an inner wall material stretched inside the column, and 23 is a plywood stretched outside the column. It is a veneer.
A plurality of the molding boards 1 are provided in the concave grooves 8 respectively.
Are fitted so as to cover the surface of the underlaying plate 23, and the molded boards 1 are fixed to the surface of the underlaying plate 23 by driving screws 24 and 25 from the surface thereof. FIG. 12 shows a molded board stopper comprising a pair of screw nails 24 and 25, a spherical washer 26 and an anchor fitting 27. The spherical washer 26 is provided with an engaging hole 28 for passing the screw nail 24 at the center position and the screw nail 2 at the eccentric position.
An engagement hole 29 through which the hole 5 passes is formed. The anchor fitting 27 has a crown shape and has a screw nail 2 at the center.
An engagement hole 30 for passing the hole 4 is provided. When fixing the forming board 1 to the surface of the underlaying plate 23 by using the stopper, first, the screw nail 25 is passed through the engaging hole 29 and a screw driver is used, and as shown in FIG. A screw nail 25 is driven into the forming board 1 obliquely downward, and the tip end of the screw nail 25 is screwed to the underlaying plate 23 and the column 21. Next, the screw 24 is passed through the engagement hole 30 to engage the anchor fitting 27 with the head of the screw 24, and the screw 24 is further passed through the engagement hole 28, and the screw nail is used by using a screwdriver. 24 is horizontally driven into the molding board 1, and the tip of the screw nail 24 is attached to the underlaying plate 23 and the support 2.
Screw on 1. Then, the head of the screw 25 is pressed down by the anchor fitting 27. By driving the pair of screw nails 24 and 25 in this manner, the spherical washer 26 presses the surface of the molding board 1, and a spherical depression is formed on the surface of the molding board 1 by the pressing force. The forming board 1 is firmly fixed to the surface of the subboard 23. Since the irregularities 6 are formed on the back surface of the molding board 1 as described above, a ventilation gap 31 is formed between the molding board 1 and the surface of the underlaying plate 23. Then, a wire mesh 32 formed by welding a reinforcing bar having a diameter of several millimeters in a grid pattern is arranged in the groove 2 for arranging the reinforcing wire on the forming board 1, and the wire mesh 32 is temporarily fixed by a screw nail 34. A lightweight mortar 33 using volcanic ash as an aggregate is applied to the surface of the molded board 1 to a thickness of about 11 mm, and the mortar 33 is filled into the reinforcing groove 2 and the spherical washer 26 without any gap. The wire mesh 32 and the crown-shaped anchor metal fittings 27 etc.
Buried inside. As described above, the use of the molded board 1 in which the reinforcing groove 2, the irregularities 6, the ridges 7, the concave grooves 8 and the like are formed in advance makes the work on the construction site extremely easy,
Anyone can carry out construction without mistakes. Reference numeral 35 denotes a termite-control sheet made by impregnating boric acid into Japanese paper so that the termite-control sheet covers the back and bottom surfaces of the molded board 1 near the upper part of the foundation 20. By intervening, termites can be effectively prevented from entering. In the outer wall thus configured, the mortar 3
3 is also filled in the reinforcing groove 2 and is hardened integrally with the wire mesh 32, so that the molded board 1 is prevented from undergoing aging such as shrinkage. The mortar 33 layer is integrated with the spherical washer 26, the anchor fitting 27 and the like, and is directly supported by the lower cladding plate 23, the support 21 and the like by the screw nail 25 and the horizontal screw nail 24 facing obliquely downward, and the load on the molding board 1 is loaded. Therefore, the molded board 1 is not deformed, and the mortar 33 layer does not hang down due to aging. The small groove 9 prevents rainwater or the like from entering from the outside through the gap between the ridge 7 and the groove 8 due to the capillary phenomenon. Further, since the surface area of the back surface of the molded board 1 is increased by the irregularities 6, it is possible to relatively suppress the formation of dew even when the temperature difference between the back surface of the molded board 1 and the air in the ventilation gap 31 is large. Even if dew is formed, the moisture is discharged because the ventilation gap 31 is continuous in the up-down direction, and the moisture is released, so that the occurrence of mold, corrosion, and the like can be prevented. Further, the outer wall has extremely excellent fire resistance against an external flame. That is, mortar 33 from outside
When the mortar 33 is burned by a flame, the molded board 1 is melted by the high heat and further vaporized to form a porcelain mortar 33.
By blowing out from the pores, the surface becomes a flame and burns violently, but until the outside air enters the inside of the mortar 33, the molded board 1 does not burn even if it melts inside the mortar layer. Rather, it has a remarkably high fire resistance because it has the effect of cooling the surroundings by depriving it of heat of fusion and vaporization in the course of melting and vaporization. In this embodiment, the ventilation gap 31 is formed by forming the unevenness 6 on the back surface of the molded board 1. However, the ventilation gap is formed by forming the unevenness on the surface of the underlaying plate 23. May be performed. In addition, an uneven sheet serving as a spacer may be interposed between the molding board 1 and the underlaying plate 23. The molding board 1 is formed by the above-mentioned bead method polystyrene foam, as well as polypropylene foam, polyurethane foam, polystyrene foam, high impact styrene foam,
Other foamed plastics such as phenolic foam can be used. Since the mortar 33 is firmly supported directly on the underlaying plate 23, the support 21 and the like as described above, a decorative plate may be further stretched on the surface of the mortar 33, or a surface material may be sprayed. It is also possible to attach tiles. In this embodiment, a wooden house is taken as an example.
The outer wall structure of the present invention can also be applied to a reinforcing steel bar or a steel house having 1 as a steel frame. As described above, according to the outer wall structure of a building according to the present invention, a molded board made of foamed plastic having a groove for arranging reinforcement on the surface thereof is arranged on the surface of the underlay plate. Is fixed to the surface of the underlaying plate by driving a screw nail from the surface so that a ventilation gap is formed between the back surface of the molding board and the surface of the underlaying plate, and the reinforcing groove is provided. Since a wire mesh is arranged and mortar is applied to the surface of the molded board, while using a foamed plastic molded board that can be molded at a relatively low price as a heat insulating material, the fire resistance is excellent, In addition, there are many beneficial effects such as durability and no fear of dew condensation. Further, by using this molded board, the construction work at the construction site can be facilitated and construction errors can be prevented.
