Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for easily and quickly constructing external enclosures such as walls or roofs that require connection points in the longitudinal direction. This invention relates to a construction board that can be used for construction, and the connection points can be made elegant in appearance.

[Conventional technology and its problems]

Conventionally, when constructing the outer enclosure of a wall or roof by connecting construction boards of a predetermined length in the longitudinal direction, the construction is usually done from the bottom to the top. On steeply sloped roofs, when fixing construction boards to structural members such as the rim or main building, workers must hold them while holding the construction boards and use fasteners such as drill screws, bolts, nuts, etc. to prevent them from falling. It was stuck.

Moreover, under the above-mentioned working conditions, it is difficult to maintain a constant overlapping width between the building boards in the vertical direction at any point, making it impossible to carry out accurate construction, and making it difficult to connect the building boards to each other. There were various problems such as the location being conspicuous in appearance and significantly deteriorating the appearance of the enclosure.

[Means for solving problems]

Therefore, as a result of intensive research in order to solve the above-mentioned problems, the inventor has developed the present invention by forming side parts from both sides in the width direction of the main plate, forming fitted parts on the side parts, A construction material having a bottom part formed outward from the lower end of the side part, a rising part formed from the outer end of the bottom part, and a protruding strip facing the width direction formed at one longitudinal end of the main plate. By making it a board, when connecting points in the longitudinal direction are required in the construction of an outer enclosure such as a wall or roof, the construction can be done easily and quickly, and the connecting points can be made elegant in appearance. This solves the problems mentioned above.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 9.

Reference numeral 1 denotes a main plate having an appropriate length in the longitudinal direction, and as shown in FIG. 3, bulging stepped portions 1b whose height is higher at both sides in the width direction than on both sides of the central flat portion 1a; 1b is formed, or, although not shown, the whole is flat,
In addition, it may be formed with a high height.

Side portions 2.2 are formed on both sides of the main plate 1 in the width direction, and fitted portions 3.3 are formed at appropriate locations on the side portions 2.2. Further, bottom portions 4, 4 are formed outwardly from the lower ends of the side portions 2.2, and rising portions 5.5 are formed from the outer ends of the bottom portions 4, 4. The height position of the bottom part 4 and the height of the flat part 1a are formed to be at the same height.

The mated part 3 is the lower part of the side parts 2, 2 (closer to the bottom part 4 side)
, the side portion 2 is formed to bulge inward.

As shown in FIG. 3, a bulging strip 6 that bulges toward the surface side is formed toward the longitudinal end (upper end) of the main plate 1 in a bulging manner facing the width direction. The cross-sectional shape of the bulging strip 6 may be approximately arcuate, square, or triangular.

The outer end side of such a bulging strip 6 is configured as an upper joint portion U. Furthermore, specifically, the height of the main plate 1 is formed to differ by approximately the thickness of the main plate 1 with the bulging strip 6 as a boundary. In other words, it appears as if a stepped portion is formed. As shown in FIG. 3, when the bulging strip 6 is removed only on both sides of the main plate l and is formed up to the sloping part of the bulging step portions 1b and lb, the bulging step portions on both sides are removed. A stepped portion 7 is formed on the top surface of 1b, lb such that the upper end side is lowered one step toward the back surface side.

Moreover, as shown in FIG. 3, the bottom part 4 and the rising part 5
At the other end (lower end) in the longitudinal direction of the
is formed, and the narrowed portion is formed as a lower joint portion d. That is, at the other end (lower end) in the longitudinal direction of the bottom 4° 4, a rising portion 5.5 is formed so that it becomes narrower in the width direction, and the bottom 4 extends from this in the longitudinal direction with the step portion 8 position as a boundary. On the end side, the height is increased toward the front side by approximately the thickness of the plate. Assuming that the width of the general portion of the bottom portion 4 is 16, the width of the bottom portion 4 at the location d of the lower joint portion is formed as a width ll smaller than the width le (see FIG. 4).

In addition, since the rising parts 5, 5 are not processed in any way, the bottom part 4
．． It is formed to be taller by the amount that 4 is narrower.

In addition, the tips of the main Fi1, side portions 2.2, fitted portions 3, 3, bottom portion 4.4, and rising portions 5.5 of the lower joint portion d are folded back to the back side to form a folded edge 9. (See Figure 6).

Further, in the upper joint part U and the lower joint part d, the lower end of the upper building board A is placed on the bulging strip 6, and the upper joint part U and the lower joint part d overlap. It has a fixed structure.

Reference numeral B designates a cap material in which leg portions 11.11 are formed on both sides of the upper surface portion 10 in the width direction, and a fitting portion 1 is formed on the leg portions 11.11.
2.12 was formed.

The fitting part 12.12 is the fitted part 3.3 of the building board A.
Specifically, the fitting portion 12.12 bulges outward in a substantially triangular shape from the lower end of the leg portion 11.11.
was formed.

Similarly to the building board A, the cap material B may also be used by being connected in the longitudinal direction. Specifically, as shown in FIG. 7, a coupling means part 13 is formed at -ra (upper end) in the longitudinal direction of the cap member B, and the upper surface part on the outer end side is formed from the position of the coupling means part 13. 10. The m portion 11 and the joint portion 12 are formed so as to be narrowed by approximately the thickness of the metal plate forming the cap material B.

In such a cap material B, the side on which the joint portion 13 is formed is always the upper side in the longitudinal direction.

When the cap materials B and B are placed adjacent to each other in the vertical direction, the lower end of the cap material B at the upper position and the upper end of the cap material B at the lower position are overlapped and connected. At this time, the lower edge of the cap material B in the upper position is
(See the chain line in FIG. 8).

Furthermore, the leg portion 11 of the upper cap member B is inserted into the lower leg portion 11 of the cap member B at the overlapping location, thereby ensuring a secure connection. As an example of the inserted state, as shown in FIG. The fitting part 12 and leg part 11 at the lower end of the cap member B at the upper position are locked.

In the figure, reference numeral 14 indicates structural materials such as the purlin and the rim, and reference numeral 15 indicates base materials such as wood wool boards.

The lowest architectural boards A, A, .
is fixed to the structural member 14 with fasteners 16 such as bolts, these steps are repeated in order, the bottom layer is roofed, cap material B is fitted between adjacent architectural boards A, and , the lower joint part d of the building board A located on the upper side is polymerized and fixed to the upper joint part U of the building board A located on the lower side, and this polymerization and fixation is sequentially repeated in the lateral direction of this stage. Further, a cap material B is fitted to form an outer enclosure such as a wall (see FIG. 1).

〔Effect of the invention〕

In the present invention, from both sides of the main plate 1 in the width direction, the side portions 2,
2, and a fitted portion 3°3 is formed on the side portion 2.2;
A bottom portion 4.4 is formed outward from the lower ends of the side portions 2, 2, a rising portion 5.5 is formed from the outer end of the bottom portion 4.4, and the main plate 1
By forming a building board with a bulging strip 6 facing the width direction A at one longitudinal end of the building board A, firstly, it is possible to greatly improve the efficiency of constructing the building board A in the longitudinal direction. Secondly, it can be made to look better, thirdly, the joint can be made stronger, and fourthly, it can be processed easily with minimal processing.

To explain these effects in detail, first, architectural board A.

When connecting A in the vertical direction, the architectural board A in the upper position
The lower end edge of the roof can be brought into contact with the bulging strip 6 of the lower architectural board A, so that the bulging strip 6 of the lower architectural board A that has already been roofed can be brought into contact with the bulging strip 6 of the lower architectural board A. This serves as a support for the architectural board A, which makes roofing much easier. That is, in particular, the bulging strip 6 supports the lower edge of the building board A at the upper position, and at the same time, this supporting position can be used as a factor for determining the overlapping part of a predetermined width.

In addition, being able to support the building board A during construction allows the worker to focus only on the fixing work, which involves supporting, positioning, and fixing the relatively heavy metal building board A. It has the effect of significantly improving efficiency.

In addition, as described above, by being able to position using the bulging strips 6, it is possible to easily keep the overlapping width of the vertically adjacent building boards A, A constant during construction of an outer enclosure such as a wall. It has the advantage of being able to be roofed in an extremely orderly manner.

4 Furthermore, since the roofing is done sequentially from the bottom to the top, the bottom end of the building board A at the top position will be placed on the bulging strip 6, and even when visually viewed from below on a wall etc. The lower end of the architectural board A at the position is less noticeable due to the bulging stripes 6, which has the effect of making the appearance more elegant.

Moreover, when these architectural boards A, A are connected in the vertical direction, if the vertically adjacent main boards 1.1 overlap, the bulging strip 6 is added to the section modulus of the architectural boards A, A. It has a larger section modulus and can provide a construction board A that can be used as a strong joint.

Furthermore, although it has favorable effects on construction, appearance, etc., it has the advantage that only the bulging strips 6 are provided, and that it requires only a small amount of processing, is simple, and can be made at low cost.

Note that by forming a step 7 at one end (upper end) in the longitudinal direction of the main plate 1, and forming a step 8 that narrows at the bottom 4 and the rising portion 5, the overlapping is not only more reliable and orderly, but also watertight. It also has the advantage of being able to be polymerized.
