Description

[Detailed explanation of the invention] This invention relates to surface structural materials in buildings.
More specifically, the present invention relates to a surface structure material for buildings that can form an external wall surface with excellent waterproof properties.

Conventionally, when constructing the outer surface of a building, such as the roof or exterior wall surface, with metal plates, the metal plates are laid on supporting members (rafters, columns, etc.) and fixed with nails, bolts, hangers, etc. Many accessories are used to prevent water leakage and improve the appearance of the building's exterior. By inserting a heat insulating material on the back surface of the metal plate, a heat insulating effect and a sound damping effect when raindrops hit the metal plate are achieved.

However, even if conventional metal plates are connected one after another to form the external surface of a building, rainwater that has entered from the connected parts will travel along the back side of the metal plate and seep into the interface between the back side of the metal plate and the insulation material. In some cases, the heat insulating material peeled off from the back surface of the metal plate due to freezing, etc., and the effect of inserting the heat insulating material was significantly reduced. In addition, the water that has seeped into the metal plate corrodes the back surface of the metal plate and the back surface material, thereby reducing the durability of the metal plate.

This idea was made based on the above-mentioned circumstances, and even if rainwater were to infiltrate the back surface from the connecting parts of the surface structural members of the building, the rainwater would
It prevents the backing material installed on the back side of the surface structure material from peeling off from the back side of the surface structure material, and allows the soundproofing and heat insulation effects of the backing material to be exerted semi-permanently, improving durability in buildings. The purpose is to provide an excellent surface structure material.

Next, an embodiment of this invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view showing one embodiment of this invention, and FIG. 2 is a longitudinal cross-sectional view showing the embodiment.

A surface structure material 1, which is an embodiment of this invention, is installed horizontally on the outer wall or roof surface of a house, and is made of long plate-like members 2 made of iron, aluminum, or other metals. have

As shown in FIG. 1, the plate-like member 2 has a first folded-back part 3 that folds the end of the plate-shaped member 2 inwardly at one end in the longitudinal direction, and a second folded-back part. 4, a receiving part 6 is formed into a substantially U-shaped groove 5 by being folded back in the opposite direction to that in the first folded part 3; Along with being,
A water drainage part 8 formed in a dish-like cross section is provided with a first step 7 interposed therebetween. Further, the other end of the plate member 2 in the longitudinal direction is provided with an insertion piece 10 extending in the longitudinal direction via a second step 9. Then, by fitting the insertion piece 10 at the other end of the other plate-like member 2 into the groove 5 at one end of the one plate-like member 2, the plurality of surface structure members 1 are aligned in the longitudinal direction. It is now possible to connect.

Furthermore, as shown in FIG. 2, the plate-like member 2 has a plurality of chevron-shaped engagement parts, for example, at its upper end in the transverse direction, as an engaging part that connects the plate-like members 2 adjacent to each other in the inclination direction of the roof. The fastening portion 11 is bent, and the lower end portion in the transverse direction is bent in a substantially U-shape toward the inside of the plate member 2 so as to be able to engage with the engaging portion. Next, it is bent in the opposite direction to the substantially U-shaped bending to form a receiving groove 12, and further extends in the transverse direction from the tip of the receiving groove 12 via a third step 13, The engaging portion is formed by bending a fixing piece 14 having an insertion hole (not shown) into which a nail, bolt, or the like is inserted. Then, the surface structure material 1 is fixed to a fixing member (not shown) (rafters, columns, studs, etc.) by driving nails or the like into the insertion holes provided in the fixing piece 14, and the receiving groove in the fixed surface structure material 1 is fixed. By fitting the fastening portion 11 of another plate member 2 located below into the plate member 12, a plurality of surface structure members 1 can be connected to each other in the short direction. There is.

In the surface structure material 1, as shown in FIGS. 1 and 2, a back surface material 16 having a predetermined thickness is attached to the back surface of the flat portion 15 of the plate member 2. This back material 16
Examples include wood wool cement, gypsum board, and foamed resins such as foamed polyurethane and foamed polystyrene.
A waterproof layer 17 is formed on the side end surface of this back material 16 in a rising or falling manner from the back surface of the plate-like member 2 and joins to the back surface of the flat part 5. The corner portion where the flat portion 16 and the flat portion 15 are joined is made watertight. The waterproof layer 17 can be formed by applying a waterproof caulking material or waterproof paint, or by pasting a rubber asphalt sheet. Although it is sufficient to provide this waterproof layer 17 along both end faces of the back material 16 in the transverse direction, it may also be provided along the upper end face along the longitudinal direction.

Using the surface structure material 1 having the above-described configuration, the outer surface of a building can be formed by construction as follows. That is, the surface structure material 1 is placed on a fixing member (not shown) with the longitudinal direction of the surface structure material 1 on its side and the fastening portion 11 facing upward. Next, the surface structure material 1 is fixed to the fixing member by driving a nail or the like into the fixing member through the insertion hole provided in the fixing piece 14 of the plate-shaped member 2. Next, by fitting the insertion pieces 10 of the adjacent plate-like members 2 into the grooves 5 in the fixed surface structure material 1, the two surface structure materials 1
Connect the comrades in their longitudinal direction. Another surface structure member 1 connected to the fixed surface structure member 1 is fixed to the fixing member in the same manner as described above. Furthermore, by fitting the fastening portion 11 of the surface structure material 1 located below into the receiving groove 12 located below the fixed surface structure material 1, the two surface structure materials 1 can be attached together. Connect in the short direction. Another surface structure member 1 connected below the fixed surface structure member 1 is fixed to the fixing member in the same manner as described above.

When the outer surface of a building is formed as described above using the surface structure member 1 having the above-described configuration, the surface structure members 1 can be separated in the longitudinal direction by fitting the insert pieces 10 into the grooves 5. In addition, in the short direction, since the connection is made by fitting the fastening portion 11 into the receiving groove 12, it is possible to prevent rainwater from entering inside from the connecting portion. Even if rainwater were to infiltrate inside from the connecting portion, the plate-like member 2
Since the waterproof layer 17 that joins with the back surface of the flat portion 15 is formed in an upright shape, it is possible to prevent rainwater from entering between the back surface of the flat portion 15 and the back material 16. . Therefore, it is possible to prevent the back material 16 from peeling off from the back surface of the planar portion 15 due to rainwater entering between the back surface of the planar portion 15 and the back material 16 and freezing, as in the conventional case. Then, in the above embodiment, the back material 16 can be kept in close contact with the back surface of the flat part 15 semi-permanently, so that after the construction of the surface structure material 1, the soundproofing effect and effect of the back material 16 can be maintained semi-permanently. It can have a heat insulating effect. In addition, since rainwater is prevented from entering between the back surface of the flat part 15 and the back material 16, corrosion of the metal plate and back material due to rain water on the back surface of the plate member 2 can be prevented. The life of the subsequent surface structure material 1 can be significantly extended. Furthermore, since the surface structure material 1 has a back surface material 16 on its back surface before construction,
Unlike the conventional method, the complicated process of attaching the heat insulating material after attaching the metal plate can be omitted, and the construction can be simplified.

Although one embodiment of this invention has been described in detail above, it goes without saying that this invention is not limited to the above-described embodiment and can be implemented with various modifications within the scope of the gist of this invention. do not have.

As explained above, according to this invention, a waterproof layer is formed on the end surface of the backing material provided on the backside of the planar section of the planar structure material, which is bonded to the back surface of the planar section. Even if rainwater intrudes into the back surface of the flat part, the rainwater can be prevented from entering between the back surface of the flat part and the back surface material. Therefore, peeling of the backing material from the backside of the flat part is prevented,
By semi-permanently adhering the backing material to the back of the flat part,
The backing material can provide soundproofing and heat insulating effects over a long period of time. Moreover, since corrosion on the back surface of the plate member can be prevented, the durability of the surface structure material after construction can be maintained for a long period of time.
