Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an outer wall plate in which the sealing material with which the joint portion is filled has a high locking strength and which does not fall off or leak water.

[Conventional technology]

Generally, for the purpose of reducing the weight, reducing the cost and improving the heat insulating property, the outer wall plate formed by extrusion molding has a surface perpendicular to the extrusion molding direction of the outer wall plate 1, that is, the longitudinal direction, as shown in FIG. As an example, a large number of parallel through holes 2 ... Which are opened side by side and penetrate the outer wall plate 1 in the longitudinal direction are provided. Both longitudinal edges of the outer wall plate 1 often have a real structure or a phased structure (not shown) for the convenience of construction and a waterproof function.

In order to attach the outer wall plate 1 to the foundation 3 of the building, as shown in FIG. 11, joint portions 4 are provided at regular intervals while facing the outer wall plates 1, 1 and the through holes 2 ... The outer wall plate 1, the one end and the like near the joint 4 are fixed by nails or screws. As shown in FIG. 12, a backup material 5 is arranged in the joint portion 4, and a sealing material 6 is filled on the upper surface of the backup material 5 and liquid-tightly sealed to prevent intrusion of rainwater or the like.

The sealing material 6 is usually made of an organic material having high expansion and contraction followability and high adhesiveness.

[Problems to be solved by the invention]

However, for the purpose of reducing the weight of the outer wall plate having the through hole in the longitudinal direction, the cross-sectional area of the through hole is made sufficiently large within the range in which the strength of the outer wall plate is secured, and the space between the surface and the through hole is The wall thickness of is reduced. Therefore, even if the sealing material is filled, the bonded portion is limited to the thick portion 7 between the surface and the through hole and the part of the rib 8 between the through hole and the sealing material 6. A sufficient adhesive area between the outer wall plate 1 and the outer wall plate 1 cannot be obtained. In particular, the sealing material often shrinks and hardens over time, and the sealing material may peel off from the adhesive surface of the outer wall plate, which causes water leakage.

Further, since the above-mentioned conventional outer wall plate has a through hole having a large cross-sectional area, when cutting the outer wall plate on site and performing nail drilling for fixing the base, for example, a drill penetrates one thick wall portion 7. The outer wall plate is apt to be damaged due to an impact applied when it crosses the through-hole 2 and enters another thick portion 7, or due to a shake of a drill or the like. In order to prevent this, the operator needs to pay close attention and is prone to fatigue.

For the purpose of reducing this, a lightweight aggregate is used as a material for the outer wall plate to reduce the weight, but the physical properties are deteriorated due to a decrease in bending strength, an increase in water absorption and the like.

Furthermore, as a problem in construction, when the ends of both outer wall materials are abutted in the projecting corner part of the building and a cheap L-shaped covering method projecting corner material is used, the cross-sectional area of the through hole is generally large. It is not possible to ensure waterproofness with the easily available sealing material used.

In view of the above-mentioned circumstances, the present invention provides a method of sealing a plurality of outer wall plates when the end faces having open through holes are opposed to each other and a joint filled with the sealant is provided between the end faces to fix the sealant to the base. The locking strength can be increased, and moreover,
An object of the present invention is to provide an outer wall plate capable of easily performing a nail hole drilling process for fixing a base without damaging the outer wall plate.

[Means for solving problems]

The outer wall plate of the present invention is an outer wall plate having a number of longitudinal parallel through holes formed by extrusion molding of an inorganic material, and at least a part of the through holes has a cross-sectional area of 1 to 30 mm ^2. Characterized in that the thin through holes are gathered at least near one surface of the outer wall plate in the plate thickness direction and are distributed along the plate width direction of the outer wall plate.

[Action]

The outer wall plate according to the present invention is such that when the surface side where the fine through holes are gathered is the surface, the end surfaces where the fine through holes are open are made to face each other, and a joint portion is provided between the end surfaces to fix it to the base, Since the sealing material filled in the portion also penetrates into each of the narrow through holes and is hardened, the contact area between the sealing material and the outer wall plate is increased by the amount of contact with the inner wall of the thin through holes, and the so-called anchor is also used. The effect is produced, and the locking strength of the sealing material with respect to the joint portion becomes extremely high. As a result, the risk of falling out of joints and water leakage is reduced.

Also, since the above-mentioned narrow through holes are distributed along the width direction of the outer wall plate, when performing nail drilling work for fixing the base, make holes across these narrow through holes. It is possible to perform work easily without damaging the outer wall plate with less impact from a drill or the like. In addition, since the narrow through hole can be traversed regardless of the position of the outer wall plate where the nail hole is drilled, it is possible to immediately respond to the situation at the site.

〔Example〕

1 to 3 show a first embodiment of an outer wall plate according to the present invention. The outer wall plate 11 has a large number of parallel through holes 12 having a cross-sectional area of 1 to 30 mm ^{2 in} the longitudinal direction. Are distributed along the surface 11a in the vicinity of the one surface 11a of the outer wall plate 11.

To form an outer wall using the outer wall plate 11, the base 3
In addition, the outer wall plates 11 adjacent to each other are sequentially attached from the lower side to the upper side in contact with the other surface 11b, and as shown in FIG. Then, the joint portion 4 is formed. The backup material 5 is pushed into the joint portion 4, and the sealing material 6 is placed thereon.
However, if a pressure is applied with a spatula when filling the sealing material, a part of the sealing material will easily become a fine through-hole because the sealing material on the market contains a highly viscous agent depending on the JIS standard. However, in the narrow through hole of the present invention, it does not excessively enter (that is, does not impair the economical efficiency), and is extremely strongly bonded and fixed by its anchoring action and an increase in bonding area. Also, the end seal at the projected corner can be easily sealed with a commercially available sealing material for the same reason. Further, since the narrow through-hole 12 has a small cross-sectional area and is thin, the impact generated when drilling a hole is small, and the operator's attention to impact is remarkably small, and fatigue due to this is significantly reduced. .

When the cross-sectional area of the fine through holes is less than 1 mm ² , not only the effect of reducing the weight of the outer wall material is small, but also extrusion molding becomes difficult. If it exceeds 30 mm ² , the sealing material 6
Since it is pushed unnecessarily deeply and flows, not only is it uneconomical, but the anchor effect is also small.

The thin through-holes 12 ... Have a circular cross section, but are not limited thereto, and as shown in FIGS. 4 (a) (b) (c) (d), triangles, squares, hexagons, etc. , Shape and distribution can be freely selected.

〔effect〕

As described above, according to the outer wall plate of the present invention, when the joint portion is provided between the end faces and is fixed to the base, the sealing material filled in the joint portion is also formed in each of the narrow through holes. When it enters, the contact area between the sealing material and the outer wall plate increases, and at the same time, the so-called anchor effect is exerted, and the locking strength of the sealing material with respect to the joint portion becomes extremely high. As a result, the joints will not loosen and fall off, nor will rainwater enter.

Also, since it is possible to perform nailing work for fixing the base material by traversing a part of the narrow through holes distributed in the width direction of the outer wall plate, the impact of a drill etc. is small and the outer wall plate is not damaged. You can easily work without it. Moreover, since the narrow through hole can be traversed regardless of the position of the outer wall plate where the nail hole drilling operation is performed, it is possible to provide the outer wall plate that can immediately respond to the situation at the site.

Furthermore, the combination of the large through holes and the narrow through holes has many advantages such as excellent heat insulation, sound insulation and sealing.
