  In Patent Document 1, the downward arch shape (A) and the upward arch shape (B) are obtained by electrically controlling the tilt angle motor (M2), the lifting motor (M3), and the main motor (M1). It can be integrally formed continuously. That is, it is possible to form a building board material having a substantially S-shaped side surface shape including arc-shaped irregularities in the vertical direction along the longitudinal direction. Therefore, a beautiful slope-like roof (20) such as a building (19) as disclosed in FIG. 10 of Patent Document 1 can be easily installed. The same applies to Patent Document 2.

  However, in the forming process of the building plate material formed by the forming devices of Patent Document 1 and Patent Document 2, the building plate material is formed into an S-shape in the direction of being sent out from the forming device as described above. [See FIG. 8A]. Therefore, the movement trajectory of the front end of the building board sent out from the final roll of the molding machine is greatly swung left and right (see FIG. 8A).

  Therefore, a large space (a plaza like a material storage area) is required on the side where the building board is sent from the molding machine (see FIG. 8B). However, there are many construction sites where a large space other than a building structure cannot be secured, and in such a place, an apparatus for forming a building board material that is S-shaped in the longitudinal direction as described above is installed. However, it is impossible to actually construct the building board.

The invention according to claim 3 is the building plate forming apparatus according to claim 1, wherein the swivel is rotated so that the movement trajectory of the tip of the building plate sent out from the roll forming machine is linear. As a result, the above problems were solved.

  The above-mentioned problem has been solved by using the invention of claim 4 as the board material forming apparatus for building according to claim 1, wherein the swivel is a manual operation. According to a fifth aspect of the present invention, the above-described problem is solved by using the building plate forming apparatus for building according to the first aspect, wherein the turning of the revolving machine is performed as electric control by a motor.

  In invention of Claim 1, the board | plate material shaping | molding apparatus for construction is comprised from a roll forming machine and a turning machine.

A continuous building board is formed so as to form an S shape.

  And this roll forming machine shape | molds the board | plate material for construction, sending it out so that the width direction may become a vertical surface (Z direction). In other words, the building plate is sent out from the roll forming machine while forming a substantially S shape in the longitudinal direction on the plane. Therefore, the building plate is formed without interfering with the ground in the vertical direction. can do.

  Furthermore, the roll forming machine is installed on a turning table of a turning machine having a turning table that rotates on a horizontal plane, and the roll forming machine is rotatable on the horizontal plane. In the process of forming a building plate material, the building plate material forming apparatus is greatly moved from side to side with respect to the movement trajectory of the leading end portion of the building plate material fed from the roll forming machine.

  At this time, the building board formed while being sent out is sent out by appropriately rotating the swivel table of the swivel machine in the opposite direction to the shake of the tip part in the horizontal direction (Y direction). The building plate material is molded without being greatly shaken left and right at the front end of the building plate material that is being molded. As a result, the space in the molding process of the building plate material can be performed with an extremely small area, and space saving at the construction site can be realized.

  According to a second aspect of the present invention, roll forming is performed by rotating the swivel so that the movement trajectory of the front end portion of the building board material fed from the roll forming machine is within a linear delivery path having a predetermined width.

A driving gear 72 is attached to the driving motor 71, and a driven gear 73 is provided on the outer periphery of the turning table 4. The driven gear 73 does not need to be formed over the entire circumference of the turning table 4 or the fixed base 5, and may be formed only in a necessary turning range of the turning table 4.

  Next, the building plate 9 formed by the building plate forming apparatus will be described. The building plate 9 is mainly composed of a mountain arcuate portion 9a and a valley arcuate portion 9b. The mountain-shaped arc-shaped portion 9a and the valley-shaped arc-shaped portion 9b are formed along the longitudinal direction and the height direction (see FIGS. 6A and 6B).

  In the case where the building plate 9 is used as a roofing plate, the mountain-shaped arc 9a is an arc-shaped forming region that is convex above the building plate 9, and the valley-shaped arc 9b is recessed downward to form an arc. [See FIG. 6A]. And the board | plate material 9 for construction is formed in the substantially flat S shape seeing from the side surface along a longitudinal direction by the mountain-shaped arc-shaped part 9a and the valley-shaped arc-shaped part 9b [refer FIG. 6 (A), (B)].

  Moreover, the part used as the boundary of the mountain-shaped arc-shaped part 9a and the valley-shaped arc-shaped part 9b is called the inflection point 9c. The inflection point 9c is a portion where the mountain-shaped arc-shaped portion 9a and the valley-shaped arc-shaped portion 9b change in the building board material 9 (see FIGS. 6A, 6B, and 7A).

  The building plate 9 has rising portions 92, 92 formed on both sides of a substantially flat main plate 91, and a bent portion that bulges in a substantially semicircular shape inward at an intermediate position between the rising portions 92, 92. 92a and 92a are formed [see FIGS. 6C, 7B, and 7C]. The building plate material 9 is used together with the cap material 95, the suspension 96, and the like [see FIGS. 7B and 7C].

  The building board material 9 is disposed on the structural material or the base part, and is fixed through a hanging member 96, and the cap material 95 on the rising parts 92, 92 of the adjacent building board materials 9, 9 is fitted and fixed. The The cap member 95 is formed with fitting pieces 95b and 95b at both lower ends of a cover portion 95a having a substantially inverted U-shaped cross section. The fitting pieces 95b and 95b and the bent portions 92a and 92a of the rising portions 92 and 92 are formed. Can be constructed, and an enclosure such as a roof or a wall can be constructed by repeating this sequentially (see FIGS. 7B and 7C).

  Further, in the longitudinal direction of the cover portion 95a of the cap material 95 (corresponding to the X direction of the building board material 9), expansion / contraction concave portions 95c, 95c,... 7 (D), (E)]. The expansion / contraction recesses 95c, 95c,... Form a similar arc-shaped portion according to the shape of the mountain-shaped arc-shaped portion 9a and the valley-shaped arc-shaped portion 9b of the building board 9, and the mountain-shaped arc-shaped section 9a as with the building board 9 And a valley-shaped arc portion 9b.

  Next, a description will be given of a process of forming the building plate 9 in which the mountain-shaped arc-shaped portion 9a and the valley-shaped arc-shaped portion 9b are continuous via the inflection point 9c by the building plate forming apparatus of the present invention. The raw material Pm is a drum in which a metal thin plate is wound in a roll shape. Although not particularly shown, the drum is often arranged on the swivel table 4. The raw material Pm is inserted from the first forming roll 3 side of the roll forming machine A.

  The raw material Pm inserted into the roll forming machine A is gradually formed into a shape close to the building plate 9 in the process of passing through a plurality of forming rolls 3, 3,. When the leading end portion 9d of the building plate 9 passes through the finishing main roll portion 33 and the finishing sub roll portion 34, a valley arc portion 9b and a mountain arc portion 9a are formed by these. At this time, the building plate 9 formed by the roll forming machine A is sent out so that the width direction perpendicular to the longitudinal direction (X direction) is a vertical plane (Z direction) [see FIG. 1 (A)]. .

  In the roll forming machine A, the building plate 9 to be sent out while being formed is a step in which a mountain arc portion 9a and a valley arc portion 9b are formed, and a horizontal plane (X -Y direction) will swing greatly to the left and right sides. Here, the roll forming machine A is installed on the turning table 4 of the turning machine B, and the roll forming machine A is appropriately rotated on the horizontal plane together with the turning table 4 (see FIG. 1). The roll forming machine A is rotated on the horizontal plane so as to always be in a direction opposite to the swinging direction (XY direction) of the front end portion 9d of the building board 9 that is fed out while being formed.

  As a result, the building plate 9 sent out from the roll forming machine A reduces the deflection width in the deflection direction (XY direction) of the tip end portion 9d [see FIG. It can be moved linearly and the movement locus of the tip 9d can be stored in an elongated rectangular passage 82 extending in the X direction (see FIG. 4B).

  That is, the swing of the tip end portion 9 d of the building plate 9 that is fed out while being molded is absorbed by the turning operation of the roll forming machine A by the turning machine B. Thereby, in the board forming apparatus for building according to the present invention, the work required area of the building board 9 sent out from the roll forming machine A can be made into a substantially thin rectangular shape, and space saving of the work area can be realized (FIG. 3, see FIG.

  This operation will be specifically described with reference to FIG. First, when the front end portion 9d of the building board material 9 that is being fed out while being formed from the roll forming machine A begins to appear, the longitudinal direction (X direction) of the roll forming machine A is the same direction as the virtual line L indicating the sending direction. Yes [see FIG. 3 (1)].

  Then, the formed sheet material for building 9 is sent out from the roll forming machine A, and the roll forming process until the inflection point 9c appears from the roll forming machine A in the process of forming the valley arc-shaped portion 9b. Machine A rotates clockwise [see FIGS. 3 (1) to (4)]. When the angle arc 9a appears from the roll forming machine A, the roll forming machine A starts to rotate counterclockwise [see FIGS. 3 (6) to (8)]. In this way, the roll forming machine A performs clockwise rotation and counterclockwise rotation, whereby the building board 9 to be molded moves in a substantially linear shape and can move in a narrow space.

  In particular, in FIGS. 3 (1) to (8), the revolving machine B is manually operated by an operator or the operator so that the building board 9 can be accommodated in a rectangular passage 81 having a narrow predetermined width W. Operated by electric control. 5 (1) to (8), the movement trajectory of the leading end 9d of the building board 9 sent out from the roll forming machine A is a straight line (including a substantially straight line) extending in the X direction. The revolving machine B is controlled so that it can move along the passage 82.

  Further, as shown in FIG. 2C, when the turning table 4 of the turning machine B is turned by the electric drive unit 7, the turning of the turning table 4 and the roll forming machine A is molded. However, there may be a configuration in which automatic control is performed so that the moving direction of the front end portion 9d of the building board material 9 that is fed out can be linearly moved (including substantially linear movement).

  As the drive motor 71, a stepping motor capable of controlling the rotation angle is used. And the drive motor which used the stepping motor about the data of the longitudinal direction length of the mountain-shaped arc-shaped part 9a and the valley-shaped arc-shaped part 9b, the radius of curvature, the position of the inflection point 9c, the feed speed of the building board 9 in the building board 9 71 is input to the control unit 73. The process of forming the building board 9 while automatically controlling the rotation of the turning table 4 and the roll forming machine A will be described below with reference to FIG.

  An imaginary line L indicating the delivery direction of the building board 9 that is fed out while being formed from the roll forming machine A is set, and the leading end 9d of the building board 9 appears from the roll forming machine A with respect to the imaginary line L. From the beginning, according to the position to which the tip 9d moves, the control unit controls the rotation by an appropriate angle θ in the clockwise direction or an appropriate angle (−) θ in the counterclockwise direction based on the data.

  As a result, the leading end 9 d of the building plate 9 that is fed out while being formed from the roll forming machine A can accurately move in the rectangular passage 81. Further, as shown in FIGS. 5 (1) to (8), the same applies to the case where the leading end 9 d of the building plate 9 that is fed out while being formed from the roll forming machine A moves along the linear passage 82. An automatic control mechanism is provided.
