Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a folded plate construction board that can extremely effectively prevent the plate rattling phenomenon that occurs due to thermal expansion and contraction of folded board construction boards due to changes in outside temperature. Regarding the board.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, a corrugated folded plate outer enclosure in which mountain-shaped portions are continuous at regular intervals has been constructed using a long folded plate construction board.

However, since the folded plate construction boards constituting the folded plate outer enclosure are fixed to structural members such as the purlin and the rim using brackets,
When the construction board for folded plates thermally expands and contracts due to changes in outside temperature or when sunlight hits the sloped part of the mountain-shaped part on only one side, thermal stress is absorbed and thermal distortion occurs. Occasionally, a so-called plate noise phenomenon occurs, causing discomfort to residents.

Furthermore, there was a problem that it gave a sense of fear.

[Means for solving problems]

Therefore, as a result of extensive research to solve the above-mentioned problems, the inventors have developed the present invention by forming sloped parts upwardly outward from both sides of the bottom main plate, and connecting bends at the upper ends of both sloped parts. valley-shaped folded line parts and chevron-shaped folded line parts are formed alternately and facing the longitudinal direction at the vertical positions of the inclined part, and these valley-shaped folded line parts and chevron-shaped folded line parts are formed. By making the construction board for folded plates continuously formed from unit materials of the inclined parts, it absorbs the thermal expansion and contraction of the construction boards for folded plates, prevents the plate rattling phenomenon, and solves the above problems. It is.

〔Effect of the invention〕

In the present invention, inclined parts 2, 2 are formed outwardly and upwardly from both sides of the bottom main plate l, and connecting bending parts 3.4 are respectively formed at the upper ends of the both end inclined parts 2. Valley-shaped folded line portions 2a and chevron-shaped folded line portions 2b are formed alternately and facing in the longitudinal direction at vertical positions of By creating a construction board for folded plates that is continuously formed by
It is possible to reliably prevent the plate rattling phenomenon of the outer enclosure constructed according to the present invention, and secondly, the structure is simple and easy to manufacture, and in particular, it is a slight improvement over the conventional ready-made folded plate construction board. By doing so, it is possible to commercialize the product.

To explain these effects in detail, the construction board A for folded plates of the present invention
Since the valley-shaped folded line portion 2a and the chevron-shaped folded line portion 2b are bent in opposite directions to each other in the inclined portion 2, these valley-shaped broken line portions 2a
The inclined portion 2 can easily expand and contract in the vertical direction because the angles of the curved bent line portions 2b and 2b are wide (open), or closed (closed). Therefore, the folded architectural board A constitutes the outer envelope.

The thermal expansion and contraction that occurs in the width direction (horizontal direction in Fig. 2) due to changes in the outside temperature of A, . , thermal stress does not occur, and furthermore, it is possible to prevent the plate rattling phenomenon caused by thermal stress (see Fig. 6).

In particular, the valley-shaped fold line portion 2a and the chevron-shaped fold line portion 2b of the slope portion 2
A major feature is that these are alternately formed, and because of this, -a, when a flat plate is thermally strained, the swollen side of the plate becomes the upper or lower side, or the inner or outer side. However, in the present invention, by inflating almost the entire body on either side in advance, if the feces has the effect of expanding on one side (
(Thermal Expansion) Either the valley-shaped broken line portion 2a or the mountain-shaped broken line portion 2b acts so that its cross-sectional angle opens and closes, albeit slightly, and can absorb the thermal expansion force.

Therefore, in the past, when a construction board for folding plates thermally expands and contracts in the width direction, there is no place where the thermal expansion and contraction can be absorbed intensively, and there is no place where adjacent construction boards for folding plates are connected, or the construction board for folding plates This can be caused by the sound of metal creaking against each other due to thermal expansion and contraction between the metal fittings 6, which are fixed to the structural members 5 such as the purlins and F-edges, and external forces generated on the receiving fittings 6, etc. due to thermal stress. However, according to the present invention, the inclined portion 2 absorbs thermal expansion and contraction, and the adjacent folded construction board A.

Thermal expansion and contraction hardly affects the connection points of A and the 6 metal fittings, etc., which prevents the plate ringing phenomenon and generates only a small amount of thermal stress distortion, greatly increasing the durability of the folded architectural board A. It can be improved.

Next, the present invention only needs to form a valley-shaped folded line part 2a and a chevron-shaped folded line part 2b on the inclined part 2 of the construction board A for folded plates.
The structure is simple without increasing the number of members, and in particular, the valley-shaped folded line portion 2a is added to the inclined portion 2 of the construction board for ready-made folded plates.
By simply forming the chevron-shaped folded line portion 2b, it is possible to obtain the same construction board A for folded plates as the present invention, and furthermore, it can be provided at a low price.
