Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Industrial Application Field] The present invention relates to an architectural structure having substantially chevron-shaped portions on both sides of the cross section and a bottomed V-shaped portion in the middle thereof. The present invention relates to a method of manufacturing a building board that can be adapted to various embodiments by setting the height and width of the bottomed V-shaped part to an appropriate value and making the board approximately symmetrical or asymmetrical.

[Conventional technology and its problems, etc.]

Conventionally, there have been various methods of manufacturing architectural boards (folded boards) that have substantially chevron-shaped sections on both sides of the cross section and a bottomed V-shaped section in the middle, such as roll forming and bend forming. are doing.

In particular, most of the central part of the construction board excluding the substantially chevron-shaped parts on both sides in the width direction has a bottomed V-shaped part formed in the middle; The sections were formed symmetrically.

In other words, in the cross section of construction boards, there are some with different heights on the left and right sides, different widths on the left and right, etc., but it is not possible to change the cross section of this bottomed V-shaped part as appropriate. There wasn't. That is, the roll forming machine had a problem in that it could only form architectural boards of uniform shape. For this reason,
It was impossible to make the bottomed V-shaped portion asymmetrical.

In this way, when forming the architectural board, it is possible to gradually start from the middle part of the board in the width direction and gradually move toward both ends in the width direction.

However, in recent years, the applicant has developed a method. There was a desire to develop a so-called horizontal folded plate roof using architectural boards whose bottomed V-shaped portions were asymmetrical in cross section (Japanese Patent Application No. 60-244081), and a molding method for architectural boards corresponding to this was desired. .

[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 using a plurality of stages of upper and lower forming rolls. and the outer top and the sloping edge are respectively formed as the final shape, and the bending angle between the inner top and the middle part and the bending angle between the outer top and the middle part are the final desired angle, and the middle part The method of manufacturing a construction board involves leaving the board flat as it is, and then bending the middle part of the predetermined width into a symmetrical or asymmetrical bottomed part. In order to form a construction board having substantially chevron-shaped portions on both sides and a bottomed ■-shaped portion in the middle, the height and width of the bottomed ■-shaped portion are set to appropriate values, and The present invention can be made substantially symmetrical or asymmetrical to accommodate various aspects and solve the above-mentioned problems.Examples of the present invention will be described below with reference to FIGS. 1 to 8.

As described above, the shapes of the upper and lower forming rolls at each stage include a flat plate-shaped plate Po to be formed, and an inner top portion Pa at both ends, as shown in FIG.

Slanted edge P and outer top P6. The roll shape is such that an inclined edge P7 is formed, and the shape of each roll is different from each other.Furthermore, in the upper and lower forming roll groups around the intermediate groove surface in the 10th to 17th stages, the intermediate The gutter surface is configured to have a desired shape.

Further, the intermediate groove surface periphery may be simply formed using a bending machine instead of relying on roll forming as in the embodiment.

Next, a method of manufacturing the architectural board P will be explained.

First, the plate P to be formed. (Upper and lower adjustment pole)
At step 10, the distance between the upper and lower forming rolls at each stage is adjusted, and then the plate to be formed P is formed. The interval between the upper and lower forming rolls on the left and right sides of the upper and lower forming roll group for end forming (the upper and lower forming rolls of the first to ninth stages) is adjusted appropriately according to the width.

Then, as shown in FIG. 1, the end portions are formed. That is, first, inclined edges PS are formed on both ends of the plate to be formed P0.
and the inclined edge P (see (1) to (2) in Fig. 1), and then the parts corresponding to the inner top (P1) and the outer top (P6) to be bent (see (1) to (2) in Fig. 1). , its inner apex Pa, inclined edge P5 and outer apex P
6. Slanted edges P are bent and formed on both sides of the plate to be formed P0.

In particular, the bending angle θ between the inner apex P4 and the flat intermediate portion P0° of the plate to be formed P0 between the inner apex P4 and the outer apex P6, the outer apex P6 and the outer apex P, A flat intermediate portion P0 of the plate to be formed P0 between the inner top portion P4 and the inner top portion P4.
The bending angle θ with ゜ is made the same angle as the final desired angle (see ■ in Fig. 1). The plate to be formed P6
Let W be the width of the middle part pao. It goes without saying that the width of W increases or decreases in direct proportion to the width of the plate to be formed P0.

Next, the intermediate groove surface of the architectural board P is formed. Middle part P of this architectural board P. . The shape of the bottomed V-shaped portion is appropriately selected so as to have a desired shape. That is, the width of the intermediate portion P0° of the plate P0 to be formed is constant as W, but the width of the bottom portion P, the width of the right sloped portion P2, and the width of the left sloped portion P are set to predetermined widths. In this manner, the desired shape of the upper and lower forming rolls and the positions of the auxiliary rolls S and S are appropriately selected and centrifuged. In this case, the upper and lower forming rolls are selected depending on the width of the bottom part P1, and the auxiliary rolls S and S are selected based on the height relationship between the right inclined part P2 and the left inclined part P3 on the left and right sides. It is something to do.

Then, the inner top P4 on the left and right sides of the auxiliary rolls S, S
．． While supporting the inclined edge P, the outer top part Pb, and the inclined edge P, the desired tenth to first stages for forming the intermediate groove surface are performed.
By passing between the upper and lower forming rolls in 7 stages (see [Phase] to 01 in Fig. 2, [Phase] to O1 in Fig. 3, and fourth [Phase] to O), the left and right sides are approximately symmetrical and compared. Architectural board P with a high target height (see O in Figure 2), and approximately symmetrical left and right,
A construction board P that is relatively low in height (see O in Figure 3) and a construction board P that is asymmetrical as a whole and relatively high in height (
(see O in Fig. 4), etc.

In this case, if the width of the plate P0 to be formed is constant, the inner top P4 of the end portion thereof. Slanted edge P and outer top P6. The width W of the intermediate portion P0°, excluding the inclined edge P and the portion, is the same whether it is symmetrical or asymmetrical.

In addition, in the case of a bending machine (not shown), a punch blade is applied to an appropriate position of the intermediate portion P0°, and the positions corresponding to the bending points on both sides of the bottom portion P are bent. .

〔Effect of the invention〕

In the present invention, upper and lower forming rolls in multiple stages are used to form an inner top P4° and an inclined edge P on both sides of the plate P0 in the width direction.
, and the outer apex P1. The inclined edges P are formed into the final shape, and the bending angle θ between the inner top part P4 and the middle part P0° and the bending angle θ between the outer top part P6 and the middle part P0° are set as the final desired shape. angle, and its intermediate part P. . By making the board as it is flat, and then bending the middle part P0° of a predetermined width into an appropriate bottomed V-shaped part that is symmetrical or asymmetrical, Firstly, by forming from the end, it is possible to form architectural boards P of various shapes in an orderly manner, secondly, there are various advantages to using it as an intermediate product for building boards P, and thirdly, there are various advantages. There are effects such as being able to manufacture the architectural board P at a relatively low cost.

To explain these effects in detail, first, with the multiple stages of upper and lower forming rolls, on both sides in the width direction of the plate to be formed Pa,
The inner apex P4 + inclined edge P and the outer apex P6 + inclined edge P are respectively formed as the final shape, and the bending angle θ between the inner apex P and the intermediate part P0°, and the outer apex P6 and the intermediate part are determined. By setting the bending angle θ with P0° as the final desired angle and leaving the intermediate part P0° as it is, the intermediate part P0° has not yet reached its final shape, and this intermediate part P . There are many choices as to what type of bottomed V-shaped part to make, and by forming the bottomed V-shaped part to the desired one, both ends can be made to be approximately the same. Also, the overall cross section is different. Architectural boards P can be molded into many different types, resulting in great effects.

This can be done in the initial stage, first of all.
Inner top portions P6 having a constant shape only at both ends in the width direction. Inclined edge P5 and outer top P6. This is because by forming the inclined edge P7 in advance, the intermediate portion P0° can be subsequently formed into a bottomed V-shaped portion. By appropriately changing the height and width of the bottomed V-shaped portion, the architectural board P can be formed to be substantially symmetrical or asymmetrical.

Although the horizontally approximately symmetrical architectural board P has conventionally been widely used as a folded plate roof, the horizontally asymmetrical architectural board P that can be formed according to the present invention is disclosed in, for example, Japanese Patent Application No. 1983
-As in No. 244081, an asymmetrical folded plate-shaped architectural board P is fixed to a slanted beam on a structure as a bracket! ! At the same time, the longitudinal direction of the architectural board P is substantially perpendicular to the longitudinal direction of the inclined beam material, and both adjacent architectural boards P
, the inner top of P4. Inclined edge P5 and outer top P
If the folded plate roof is made by overlapping the 6° sloped edge P and fixed to bolts, pads, etc., the appearance will be very innovative as a horizontal roofing of folded plates, and the roof will be waterproof (watertight). It also has the effect of improving the effect of blocking snow piles.

Further, in the present invention, the inner top portion P6. Slanted edge P.

Then, the outer apex Pb and the inclined edge P7 are respectively formed as a final shape, and the bending angle θ between the inner apex P4 and the intermediate portion P0° and the bending angle θ between the outer apex P6 and the intermediate portion P0° are determined. By setting the final desired angle and leaving the intermediate part P0° flat as it is, it is extremely flat in its current state, so you can keep it in stock and use it to create the desired shape (for construction sites, dependencies, etc.). The latter stage can also be molded according to the shape (such as a shape based on a whale design, etc.). As a result, it is possible to stock intermediate products instead of final-shaped construction boards P, and it is possible to achieve an extremely superior manufacturing method that can improve storage efficiency and inventory efficiency.

In addition, an inner top portion P4 of a constant shape is provided only at both ends in the width direction.
．． By forming the inclined edge P and the outer top P6 + inclined edge P7, various architectural boards P can be formed.
The early equipment can be used as a general-purpose machine, which makes it easier to manufacture than making various special-purpose machines, and allows for construction board P.
The product itself also has the advantage of being available at a low price.

Moreover, since this architectural board P has a folded plate shape, it can be manufactured in a very versatile manner.
