The building board A is placed on the structural member 7 so as to be substantially perpendicular to it, the gate-shaped portion 8b of the washer 8 is fitted onto the rising edge 4 of the building board A, and the horizontal mounting piece 8a is It is placed on the structural material 7 and fixed with bolts or the like.

At this time, the pressing piece 8c of the washer 8 is in a state of pressing the bottom part 3 of the building board A (see FIGS. 2 to 5).

Then, the engaging protrusion 5b of the engaging part 5 of the adjacent building board A is engaged with the engaged groove 2a of the engaged part 2 of the building board A, and these steps are repeated sequentially to form the W root. Alternatively, construct an outer enclosure such as a wall (see Figs. 1 and 2) [Effects of the Invention] In the present invention, the engaged portion 2 is formed to bulge upward on one side of the main plate 1. An engaged groove 2a is provided on the main plate l side of the engaged portion 2.
A substantially horizontal bottom portion 3 is formed outwardly from the outer lower end of the engaged portion 2, a rising edge 4 at the outer end of the bottom portion 3 is bent, and the other side of the main plate 1 has a substantially horizontal bottom portion 3. , downward side 5a
and an engagement protrusion 5 that projects inward from the lower end of this side portion 5a.
The architectural board A on which the engaging part 5 consisting of b is formed is a structural material 7
The gate-shaped portion 8b of the washer 8, which is placed substantially orthogonally to Mounting piece 8a
is fixed to the structural material 7, and the engaging protrusion 5b of the engaging part 5 of the adjacent building board A is engaged with the engaged groove 2a of the engaged part 2, and these steps are repeated sequentially to complete the roofing. By using this outer envelope, firstly, it becomes an extremely strong mounting structure against positive and negative loads, and secondly, it can cope well with thermal expansion and contraction in the longitudinal direction of the building board A. Thirdly, it has good rain protection, and fourthly, it can be constructed easily and quickly.

To explain these effects in detail, the construction board A is placed on the structural material 7, and the gate-shaped portion 8b of the washer 8 is placed on the rising edge 4.
while attaching the horizontal mounting piece 8a of the washer 8 to the structural member 7.
The outer enclosure is constructed by fixing the construction board A to the construction board A, engaging the engaging protrusion 5b of the adjacent construction board A with the engaged groove 2a of the construction board A, and repeating these steps one after another. At this time, the engaged groove 2a and the engaging protrusion 5b at the engagement location are engaged in a substantially tight state, resulting in an extremely strong mounting structure.

Therefore, the mounting can be extremely strong against alternating positive and negative loads such as wind pressure loads.

Second, in the enclosure of the present invention, the building board A is not fixed onto the structural member 7 by bolts, welding, etc., but the gate-shaped portion 8b of the washer 8 is attached to the rising edge 4 of the building board The horizontal mounting piece 8a of the washer 8 is fixed onto the structural member 7 while being fitted onto the structural member 7. Therefore, the building board A can slide on the structural member 7. Therefore, the building board A in the outer envelope of the present invention can satisfactorily cope with thermal expansion and contraction caused by changes in outside temperature.

Since it can cope with thermal expansion and contraction in this way, thermal stress does not occur, and it is possible to prevent the occurrence of thermal distortion in the building board A, and also to prevent the plate part phenomenon of the outer envelope.

Thirdly, a gutter-like portion is formed by the outer side, bottom portion 3, and rising edge 4 of the engaged portion 2 of the construction board A, and thereby the engagement portion between the engaged portion 2 and the engaging portion 5 is formed. Even if rainwater or the like intrudes from the gutter, the rainwater can flow into the gutter-like part and flow out to the outside, making it possible to control the rain extremely well.

Fourthly, the outer enclosure of the present invention allows the gate-shaped portion 8b of the washer 8 to be fitted onto the rising edge 4 of the building board A, while the horizontal mounting piece 8a of the washer 8 is fixed onto the structural member 7. Then, all that is left to do is to engage the engaging part 5 of the adjacent building board A with the engaged part 2 of the building board A, and the enclosure can be easily created, resulting in extremely high workability. It can be made into an outer shell.

In addition, the band-shaped standard material that is the base material for forming -g architectural boards has a tolerance dimension on the plus side, and when roll-forming is performed using this, the edges of the architectural board In many cases, they are formed in a large size, making construction difficult or impossible. It was also sometimes roll-formed into architectural boards.

In this regard, in the present invention, if the folded edge 4a is provided at the end of the construction board A inwardly or outwardly from the upper end of the rising edge 4, the width of the standard material is within the allowable range without cutting with a slitter. Even if it becomes wider, it will only be slightly longer as shown by the chain line in Figure 2, and will not cause any inconvenience during construction.
By not using a slitter, it can be made cheaper and
The edges of the standard material are generally better rust-proofed than other parts, and as a result, the architectural board A of the present invention itself can be made more suitable from the standpoint of rust-prevention.
