Description

[Detailed Description of the Invention] The present invention relates to a construction board used for wall boards, roof boards, etc., which is easy and quick to construct, has strength, and has good rain protection.

Conventionally, there are various types of architectural boards used for wall boards, roof boards, etc.

However, those with a simple shape had the disadvantage that rainwater would flow around to the back side, making it impossible to shut off the rain, and that they were weak in strength.

However, the construction that improved the rain protection had the disadvantage that the construction was complicated, and the construction required skill and troublesome work.

Therefore, in the present invention, one side of the main plate forms a downwardly sloping part, a horizontal part is formed outside the lower end of the main plate, and a bulge protruding from the upper surface is provided in the middle of the horizontal part. The upper end forms a folded edge with the same thickness as the bulging strip on the upper surface, and the other side of the main plate forms a sloped part facing outward and downward. The height of the section is the height from the top surface of the main plate to the bulging strip, and a horizontal section is formed outward from the slope, and the end thereof is bent downward to the same thickness as the bulging strip. The width of the folded edge and the horizontal part on the lumbosacral side is close to the width of the horizontal part with the bulging strips, so the construction can be done easily and quickly. It is strong in terms of strength, can be made well by preventing capillary phenomenon with the voids in the polymerization part, and has an elegant appearance that eliminates the above-mentioned drawbacks.

To explain the structure with reference to the drawings, A is a building board, and 1 is the main board of the building board A, which has one or more peaks or valleys.

On one side of the main plate 1, an inclined part 2 facing outward and downward is formed, and a horizontal part 3 is provided outside the lower end of the inclined part 2, and a bulging strip 4 is formed in the middle of the horizontal part 3. ing.

Reference numeral 5 denotes an inclined edge outward and upward from the end of the horizontal portion 3, and the upper end thereof forms a folded edge 6 having the same thickness as the bulging strip 4 on the upper surface.

Reference numeral 7 denotes a downwardly inclined portion on the outside of the other side of the main plate 1, and the height to its lower end is from the upper surface of the main plate 1 to the outer side of the lower end of the inclined portion 7, and a horizontal portion 8 is formed at the outer end of the horizontal portion 8. A folded edge 9 having the same thickness as the bulging strip 4 is formed by bending further downward.
The width of the horizontal portion 8 is approximately close to the width of the horizontal portion 3.

10 is a heat insulating material such as foamed synthetic resin attached to the back side of the building board A, 11 is a bolt, 12 is a washer, 13 is a backing,
14 is a structural material such as a purlin or a rim, and 15 is a sealer.

Since the present invention has the above-mentioned structure, the building board A is placed on the structural member 14, and the left side of the adjacent building board 1 is placed on the horizontal part 3 and bulging strip 4 of the building board 1. The horizontal part 8 of the wall or roof is placed, the bolts 11 are inserted through the washers 12 from the upper surface of the horizontal part 8 where the bulging strips 4 are present, and the bolts 11 are screwed onto the structural members 15, which are repeated in order to fix the wall or roof. It is something to do.

When the roof is constructed as in the present invention, the overlapping part has a gap formed by the bulging strip 4, the horizontal portion 3°8, and the folded edge 9, the horizontal portions 3, 8, the bulging strip 4, the slanted portion 7, the slanted edge 5, A gap is formed by the folded edge 6.

Therefore, rainwater that enters from the upper folded edge 9 is first prevented by the lower protruding strip 4, but rainwater that exceeds this enters the right side of the protruding strip 4; Since a sloped gap is formed by the sloped edge 5 and sloped part 7 of building boards A and A, it is completely prevented by this part from rising, and these do not cause capillary action. The infiltrated rainwater flows downward between the upper and lower horizontal parts 3 and 8 and is drained to the outside.

In addition, in the present invention, since the inclined part 7, the horizontal part 8, the folded edge 9, the inclined part 2, the horizontal part 3, the bulging strip 4, the inclined edge 5, and the folded edge 6 are formed continuously, the overlapping part This increases the section modulus at certain points, making it possible to provide a structural board with strong strength.

Since the end of the horizontal part 8 is folded back to form a folded edge 9, the lower horizontal part 3 is well pressed against the horizontal part 3 without creating a gap, and since the cut end is not visible, the patient can take a graceful nap.

Furthermore, the folded edges 6 and 9 make surface contact with the adjacent construction boards and do not damage the adjacent construction boards, so that they can withstand long-term use without corrosion.

Conventionally, in this type of device, the upper end of the inclined edge 5 was formed to protrude outward horizontally.

However, the width of the raw material board differs depending on the production at that time, and if the left dimension of the construction board is accurate, the width of the horizontal protrusion at the right end will be different, and the construction board The one in which a foamed synthetic resin layer is pasted on the back side of A requires the labor of having to change the left edge of the foamed synthetic resin layer, but with the present invention, the folded edge 6 only becomes longer if the board width is wider. Therefore, the left edge of the foamed synthetic resin layer can be adhered to a certain point, which saves time and effort.

In addition, the folded edge 6 connected to the inclined edge 5 has an upper inclined portion 7.
The back side of the board is well pressed to make it watertight, making it watertight, making it effective for waterproofing, and it is also elegant because the cut of the construction board cannot be seen from below.

In addition, in the present invention, since the overlapping part of adjacent building boards A and A is a valley, the bolt 11 enters the valley and is not exposed to the outside of building board A, so there is no chance of injury due to contact with this. There are no scratches and the appearance is elegant.

In addition, construction boards that are fixed at the peaks cannot be firmly attached unless a metal fitting is installed inside the peak, but since the present invention uses metal fittings that fit into the valley, there is no need for metal fittings, making it possible to reduce the cost. It has the effect of

In addition, if a sealer 15 is interposed between the folded edge 9, the bulging strip 4, and the horizontal portions 3 and 8, it becomes even more watertight and the waterproof effect is further improved.
