Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a construction board that can be bent in an orderly and reliable manner by forming bent portions of appropriate shapes on both sides of the main board and having a corrugated construction board on the entire surface. Regarding molding equipment.

Generally, long architectural boards have a corrugated shape in the longitudinal direction (height 17-rL/TrL~2771,/WL)
When formed into a material, the section modulus of the building board increases and a strong building board can be provided.

However, after the upper and lower forming rolls form a waveform of the same height over the entire surface of a flat plate-shaped workpiece, multiple groups of upper and lower forming rolls form an appropriate shape on both sides of the workpiece. When the bent part is rolled out, the waveforms at each corner of the bent part are almost crushed, and the corner part of the bent part is !
The construction board formed in this way expands and contracts differently on both sides and in the center, causing distortion in the entire construction board, especially at bent parts, which meander in the longitudinal direction or curve. It was formed into a ridged shape. This means that even if corrugated and reinforced, the construction board will not be able to be used for roofing or walls, or will not only have poor rain protection, but will also reduce the commercial value of the construction board itself by half. There were some drawbacks such as being exposed. Therefore, the present invention provides a forming machine that sequentially forms architectural boards in which bent portions of appropriate shapes are formed on both sides of the main board and the entire surface is formed into a corrugated shape.
Upper and lower corrugated rolls are provided to form a corrugated shape in the direction of forming progress so that both sides of the flat workpiece are higher than the center. By using a construction board forming device equipped with a plurality of upper and lower forming rolls etc. for bending, the entire surface is formed into a corrugated shape, and bent portions of appropriate shapes are formed on both sides of the main board. When forming a plate, a series of roll forming methods, which were previously considered impossible, can be bent very orderly and reliably, and the bending part does not meander, eliminating the above-mentioned drawbacks.
The molding device is also simple and can be provided at low cost.

Its structure will be explained.

Since it is substantially the same as that of the second embodiment, the explanation will be omitted.

Next, the effects will be explained.

In the present invention, suitable shapes are provided on both sides of the main plate P1. In a forming machine that sequentially forms a building board P having a bent portion P2 and a corrugated entire surface, at an initial stage, a flat workpiece P is formed.

Since upper and lower corrugated rolls are provided to form a corrugated shape in the forming progress direction so that both side parts are higher than the center part, a flat plate-shaped workpiece P is formed between the upper and lower corrugated rolls. By passing the workpiece P. The entire body is formed into a wavy shape in the direction of molding progress, and the wavy shape is formed such that the height at both sides is higher than the height at the center. A workpiece P formed by these upper and lower corrugated rolls. In this case, the length in the longitudinal direction of both side portions forming the high corrugated portion is formed to be slightly shorter than the length in the longitudinal direction of the central portion forming the low corrugated portion,
In addition, the longitudinal elongation of the low-height corrugated portion at the center is regulated by the high-height corrugated portions on both sides, resulting in artificial distortion (see Figures 9 and 10). occurs. In the upper and lower corrugated rolls formed in this manner, the convex portions for making the corrugations may be formed into an hourglass shape as a whole, and the roll configuration can be simplified. Further, in the present invention, the workpiece P is corrugated at the rear stage of the upper and lower corrugation rolls. A workpiece P that has been made into a corrugated shape by providing a plurality of upper and lower corrugated rolls etc. that bend and form a bent portion P2 on both sides of the workpiece P.
, the high corrugated part of the corner formed as the bent part P2 is compressed by the pressure from above and below of the upper and lower forming rolls, and at the same time bending stress is generated due to the bending. A compressive load is applied to the area as a whole), and the corrugated part with a high height at the corner part is crushed, and that part, that is, the bent part P2, extends in the longitudinal direction, and the elongation By doing so, it is possible to eliminate the artificial distortion that occurs in the center of the waveform with a low height, and the end face of the architectural board P can also be finished to be substantially straight when viewed in plan. By combining the upper and lower corrugated rolls with different heights of the corrugation on both sides and the center, this is the first construction product that has been made into a corrugated shape only by the roll configuration and has bent portions P2 formed on both sides. The present invention provides an apparatus that can form the plate P in an extremely orderly manner.By slightly processing only the upper and lower corrugated rolls, the present invention can be widely applied to various conventional roll forming machines, and is an inexpensive roll forming machine. The construction board P formed by such a roll forming machine has no distortion in its entirety, does not have an undulating shape, and has a curved part P2. It has an orderly finish that meanderes or curves in the longitudinal direction, and the product value is extremely high.This makes it easy to construct outer structures such as roofs or walls. , it can be done simply and quickly, and the rain specifications can be improved.In addition, in the above explanation, in the upper and lower corrugated rolls 1a and 1b, only the upper corrugated roll 1a is made into an hourglass shape, but it is not limited to this. Even if both the upper and lower parts are shaped like an hourglass, or only the lower corrugated roll 1b is made like an hourglass, the same effects as described above can be obtained.

The same applies to the upper and lower corrugated rolls 1''A, l''b. Further, in the present invention, the entire surface is formed in a corrugated shape, but the present invention does not necessarily have to be formed on the entire surface, but as long as the condition that a high-height corrugated portion is always present at the corner of the bent portion P2 is satisfied. It has the same effect as.
