The present invention also relates to a curved construction board that allows rainwater to drain well.

[Conventional technology and its problems, etc.]

Recently, various construction boards with curved eaves tips have been used on the roofs of station platforms, factories, gymnasiums, etc. Among them, a long metal architectural board (commonly known as a "folded board") with a roughly V-shaped cross section has sloped parts on both sides of the bottom and connecting bent parts on both sides. A curving method for curving a longitudinal direction to an appropriate curvature when viewed from the side, a curving forming device,
Research and development of curved architectural boards and the like are actively being conducted.

In order to form a curve in this way, depending on the height and depth of the cross section of the architectural board, the amount of shrinkage in the longitudinal direction is
Rib forming is done by press working, etc.

However, the height of the ribs at the bottom is quite large. This is because its bottom is lower than the neutral axis,
This is because the amount of shrinkage in the longitudinal direction is required to be the largest.

As a result, rainwater accumulates in the grooves between the ribs, making it difficult to drain the water, leading to serious problems such as premature corrosion of the rib-formed areas.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 16.

A is a long metal folded construction board, which is used as a roof board or wall board of a steel frame or reinforced concrete structure. 1 is the bottom of the folded construction board A, which has a substantially flat cross section, and slopes 2.2 are formed outward and upward from both sides of the bottom 1. This inclined portion 2.2 is formed with a relatively high height. Connecting bent portions 3.4 are bent at the upper ends of the inclined portions 2.2.

There are a plurality of embodiments of this connecting bending part 3.4, and in this first embodiment, as shown in FIGS. 1 to 6, 10, etc., the connecting bending part 3 is A substantially horizontal top portion 3a is formed outward from the upper end of the slope portion 2 on one side (the right side in FIG. 3), and a lower ridge portion 3b is bent above the outer end of the top portion 3a. . In addition, the connecting bending portion 4
A substantially horizontal top portion 4a is formed outwardly from the upper end of the inclined portion 2 on the other side of the bottom l (left side in FIG. 3), and above the outer end of this top portion 4a, the lower part 3b is formed. While covering, join together. An upper part 4b is formed.

Specifically, the lower part 3b is formed into an arc-shaped part that extends outward from the upper end of the vertical piece and then goes inward, and the upper part 4b extends inward from the upper end of the vertical piece. bulging,
Then, an outwardly tightening circular arc portion is formed, and an outwardly extending arcuate edge is formed after descending from this outer end.

As long as the upper ridge part 4b can be fastened to the lower ridge part 3b in this way, it is not limited to the shape of the embodiment.

In addition, as a second embodiment of the connecting bending portion 3.4,
As shown in FIGS. 12 and 13, the connecting bending portions 3, 4
In each case, chevron portions 3c and 4c each having a trapezoidal chevron-shaped cross section are bent toward the upper end of the slope portion 2.2. In this case, one side is formed to be larger by about the thickness of the other side so that the other side of the folded architectural board A is coated and superposed on the side of the side piece 3c.

Moreover, as a third embodiment of the connecting bending parts 3 and 4,
As shown in FIG. 16, the connecting bent portion 3°4 has substantially horizontal top portions 3a, 4 outward from the upper ends of the inclined portions 2, 2.
a is formed, and this top portion 3a.

Above the outer end of 4a, inverted portions 3d and 4d are bent such that the top pieces 3e and 4e face inward toward each other.

The folded plate-like building board A formed by the bottom l inclined part 2.2 and the connecting bent part 3.4 is made of a single long metal plate that is integrally formed by a multistage upper and lower roll forming machine. It is molded,
The right lateral protrusions 5a, left lateral protrusions 5b, and 6.6, which will be described later, are not bent but are formed linearly in the longitudinal direction. Further, each corner angle of the folded architectural board A is formed almost squarely, but in some cases it may be formed arcuately with a relatively small radius.

5a and 5b are a right horizontal ridge and a left lateral ridge. The right lateral ridge 5a and the left lateral ridge 5b are provided on the bottom 1. First, the right lateral ridge 5a is provided on the bottom. It is bent from one side (the right side in FIG. 3) to the other side (the left side in FIG. 3) on the upper surface side or the lower surface side of the bottom part 1. Further, the left horizontal protrusion 5b is bent toward one side (right side in FIG. 3) from the other side (left side in FIG. 3) of the bottom l, and toward the top or bottom side of the bottom l.

What is the overlapping gap (interval where they overlap) between the tip of the opposing right horizontal protrusion 5a and the tip of the left horizontal protrusion 5b?
It is formed as JIa. That is, it is provided as a groove portion of the bottom portion 1.

The right horizontal protrusion 5a and the left horizontal protrusion 5b are formed to have substantially the same cross section in the longitudinal direction (extending direction), and their tip portions are formed to narrow rapidly. In particular, at the tip of the right horizontal protrusion 5a and the tip of the left horizontal protrusion 5b between the overlapping parts, the amount of shrinkage that combines both (the amount of shrinkage due to the formation of the protrusion in the longitudinal direction of the bottom part 1) is greater than that of the other. It is configured to be equivalent to the amount of contraction of the right horizontal protrusion 5a or the left horizontal protrusion 5b at the location.

Furthermore, the right horizontal protrusion 5a and the left horizontal protrusion 5b are configured to be staggered with respect to the longitudinal direction of the bottom l. That is, assuming that the right horizontal protrusion 5a and the left horizontal protrusion 5b are a pair, this pair is continuously formed in the longitudinal direction of the bottom portion 1.

When such a right horizontal protrusion 5a and a left horizontal protrusion 5b are taken as a cross section, if they are continuous in the longitudinal direction of the bottom part 1, they may be formed in a wave shape or in a sawtooth shape.

In addition, there are a plurality of embodiments in which the right horizontal protrusion 5a and the left horizontal protrusion 5b are viewed in plan, and as shown in FIGS. The direction is substantially perpendicular to the longitudinal direction of the bottom portion 1, or, as shown in FIG. It may also be formed into a shape.

Furthermore, as shown in FIG. 5, there may be an overlapping portion surrounding either one of the ends of the horizontal protrusions.

Reference numeral 6 denotes a protrusion, which is bent on the outer or inner surface side of the inclined portion 2.2, and the direction in which the protrusion 6 extends is perpendicular to the longitudinal direction of the folded construction board A (reference line). The protrusion 6 is oriented at an appropriate angle (for example, right angle, etc.) with respect to the protrusion 6, and is formed so that the protrusion 6 gradually becomes smaller as it goes upward.

Specifically, the cross section of the protrusion 6 is formed into a wave shape when continuous, or is formed into a substantially sawtooth shape when continuous (see the drawing). In reality, the cross section of the protrusion 6 is often wave-shaped. Furthermore, when viewed in a direction perpendicular to the surface of the inclined portion 2 on which the protrusion 6 is formed, the width thereof is formed so as to gradually become narrower as it goes upward (see drawing).
By forming the ridge 6, if the amount of contraction in the length of the longitudinal direction of the inclined part 2 is to be gradually reduced as it goes upward, then the width of the inclined part 2 can be formed so that it gradually becomes wider as it goes upward. There are multiple examples in which the protrusion 6 is provided, and how it is provided is determined experimentally depending on the position 5 of the neutral axis of the folded architectural board A, the material, etc. That is, in the first embodiment in which the protrusion 6 is provided,
It is provided over the entire length of the inclined portion 2 from its lower end to its upper end (see FIG. 1). Moreover, from the lower end of the inclined part 2,
It is provided near the upper end, or the inclined part 2
A protrusion 6 may be provided from the lower end of the connecting bend 3.4 to an intermediate position.

The base of the right horizontal ridge 5a and the base of the ridge 6 are formed continuously, and the base of the left lateral ridge 5b and the base of the ridge 6 are formed continuously.

Such a right horizontal protrusion 5a, a left horizontal protrusion 5b, a protrusion 6°6,...
* is formed by press working after forming the longitudinally linear folded plate-like architectural board A, and only after they are bent can the longitudinal direction be bent to a desired curvature. The right horizontal protrusion 5a, the left horizontal protrusion 5b, and the protrusion 6.6 are formed continuously in the longitudinal direction of the folded construction board,
Alternatively, they are formed at appropriate intervals. Even when formed continuously, curved portions with appropriate curvatures may be provided at the end portions (e.g., at the eaves) of the straight folded architectural boards A.
(see FIG. 1), and even when they are provided at appropriate intervals, they may be provided over the entire longitudinal direction of the folded architectural board and formed into an arch shape with a large curvature.

If the bottom l is wide, one or more (one peak in FIG. 11) bulges 7 having a trapezoidal cross-section are formed in the middle thereof. The inclined surfaces on both sides of this bulging portion 7 are
The same height as the above-mentioned slope part 2.

The protrusions 6 formed on the inclined portion 2 are also provided on the inclined surface having the same inclination angle (see FIG. 11). Although not shown, a heat insulating material such as foamed synthetic resin may be attached to the back surface of the curved construction board.

To explain the construction of a roof or wall using the curved construction board, the curved construction board is placed between the adjacent brackets 8 and 8, and at the same time, the longitudinal direction of the curved construction board is It is made to be substantially orthogonal (including orthogonal) to the longitudinal direction of the structural members such as The connecting bent portions 4 of the plates are connected and fixed, and these steps are repeated one after another to form an overall slanted, curved eaves, etc.
