Description

  The present invention relates to a hanging member used for a fixture used for fixing a folded plate, and more particularly to a hanging member that has high strength and can suppress scattering of the folded plate.

It is thought that the scattering of the folded plate occurs as follows.
When a strong wind is received, the keraba wrapping of the keraba portion is deformed or dropped, and air flows into the fold plate from this portion, the internal pressure increases at once, and the fold plate rises. And at this time, the negative pressure by blowing up also acts on the upper surface of the folded plate roof, and a powerful negative pressure destructive force is generated in the folded plate by these synergistic actions. As a result, the hanger holding the folded plate breaks, whereby the folded plate is further deformed, the deformed folded plate receives a large load, the hanger breaks in a chain, and the folded plate is scattered. .

  In order to suppress the occurrence of such a phenomenon, it is considered necessary to firmly configure the keraba portion, but it is also considered important to ensure the strength of the suspension. This is because there is inevitably variation in the material strength of the hanger, and the folded plate is thermally expanded and contracted by solar radiation or the like, and a load is applied to the fixing bracket and the hanger, causing a decrease in strength over time.

In this regard, a suspension as disclosed in Patent Document 1 below has been proposed.
This suspension is provided with a reinforcing rib extending along a direction intersecting with the longitudinal direction of the suspension on the collar having a cross-sectional shape, and the strength of the collar is increased so that the suspension is a flange of the folded plate. It is intended to prevent you from leaving.

  However, since the ribs of the hanging member are reinforced by the ribs, there is a difficulty in that variations in strength are likely to occur.

  That is, the rib is formed by pressing using a mold, but the strength of the rib portion is likely to vary depending on the conditions related to the press, such as the material, press oil, and pressure. For this reason, it is difficult to obtain a product having a stable strength, and on the contrary, there is a risk of facilitating variation in the strength of the hanger, which is one of the causes of the folded plate scattering.

  Accordingly, the main object of the present invention is to suppress the scattering of the folded plate by suppressing the variation in the strength of the suspension and withstanding the load.

Means for this purpose is a hanging member made of a metal plate having a locking portion at the upper end portion to which the collar portion of the folded plate is locked, and a bent portion for folding and superposing the metal plate of the material is formed in part. And an overlapping portion extending from the bent portion is formed in the locking portion ,
The opposing surfaces of the overlapping portion and the overlapping portion of the overlapping portion are suspension members formed on a rough surface.

  A superposition part is formed in the hanging part, and the superposition part can suppress the shape change of the locking part and can supplement the strength. In addition, since the overlapped portion is formed by folding at the bent portion, the unity is high and the shape retaining ability is good.

  As described above, according to the present invention, the shape retaining ability of the locking portion is high, so that the strength can be improved. As a result, it is possible to suppress the scattering of the folded plate.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of the hanging element 11, and the hanging element 11 is attached to the upper part of the roof plate mounting bracket 21 as shown in FIG. 2. The roof plate mounting bracket 21 shown in FIG. 2 is used when forming a double folded plate roof, and is an example of various roof plate mounting brackets 21. In addition, the roof plate mounting bracket 21 may be a tight frame, for example, and the shape of each part of the hanging element 11 is appropriately set depending on the configuration of the roof plate mounting bracket.

  The hanging element 11 is formed by bending a single metal plate and pressing it into a predetermined shape. The outline shape has the latching | locking part 12 for latching the folding plate which comprises a roof in an upper end part, and has the attaching part 13 for attaching to the roofing board mounting bracket 21 in the downward direction. .

  The locking portion 12 includes a base portion 12a that is bent at a right angle from the upper end of the vertical piece 14 that stands vertically and forms an inverted L shape, and a tip portion 12b that extends obliquely downward from the tip of the base portion 12a toward the vertical piece 14 side. Have. The locking portion 12 is formed wider and longer than the lower end of the attachment portion 13. For this reason, it is formed diagonally so that both sides in the width direction of the vertical piece 14 become wider toward the upper side.

  The attachment portion 13 has a plate-like fixing piece 13 a that bends in the opposite direction to the locking portion 12 from the lower end of the vertical piece 14. A mounting hole 15 through which the fixing bolt 22 is inserted is formed in the central portion of the fixing piece 13a.

  In the hanging element 11 having such a general shape, a bent portion 16 is formed at the end portion in the length direction of the fixed piece 13a to fold and superpose a metal plate of material. The folded portion at the bent portion 16 overlaps with the fixed piece 13 a, the vertical piece 14, and the outer surface side of the locking portion 12 to form an overlapped portion 17. The overlapping portion 17 has the same width as the fixing piece 13a at the portion overlapping with the fixing piece 13a, and is wider than the fixing piece 13a at the portion overlapping with the vertical piece 14 and the locking portion 12, so The width is set narrower than the portion 12. Also, upwardly projecting ribs 18 and 17a having a substantially semicircular shape in plan view are formed at portions corresponding to the lower ends of the fixed piece 13a and the vertical piece 14. As shown in FIG. 3, the ribs 18 and 17 a are integrally formed at overlapping portions.

  Further, an attachment hole 17b having the same shape as the attachment hole 15 formed in the fixed piece 13a is formed in a portion corresponding to the fixed piece 13a in the overlapping portion 17. The attachment hole 17b is formed by punching in a polymerized state. As shown in FIG. 3, the unity at the attachment holes 15 and 17b is also increased.

  Further, the overlapping portion 17 is set to a length up to the base portion 12 a of the locking portion 12. This is because the deformation of the locking portion 12 is likely to occur at the corner portion of the base portion 12a that is bent in an L shape, so that at least the deformation at this portion needs to be suppressed.

  In addition, the superposition | polymerization part 17 can also be formed in an inner surface side, as shown in FIG. In the following description, parts that are the same as or equivalent to those in the above configuration are denoted by the same reference numerals, and detailed description thereof is omitted.

  5 and 6 show an example of the hanging element 11 in which the bent portion 16 is formed on both side edges of the vertical piece 14 and the locking portion 12. 5 has the overlapping portion 17 on the outer surface side, and the hanging portion 11 in FIG. 6 has the overlapping portion 17 on the inner surface side.

  Moreover, the superposition | polymerization part 17 can also be formed in the width | variety corresponding to the part to superpose | polymerize, as shown in FIG.

  The hanging element 11 shown in FIG. 8 is an example in which receiving portions 19 having an inverted L-shaped cross section having overlapping portions 17 are formed on both sides of the fixing piece 13a in the width direction. The receiving portion 19 is a portion that receives the lower surface of the folded plate that is locked to the locking portion 12.

  FIG. 9 shows an example in which the bent portion 16 is formed at the distal end edge of the distal end portion 12 b of the locking portion 12. In this case, the tip edge of the fixed piece 13a, which is the end of the metal plate as the material, and the corresponding portion of the overlapping portion 17 are aligned as shown in FIG. 9A, but as shown in FIG. 9B. One may be folded and the other wrapped.

  FIG. 10 shows an example of a round-hanger type hanging element 11. In this hanging element 11, the form of the engaging part 12 at the upper end part is substantially arc-shaped in cross section, and the attachment part 13 below it is formed perpendicular to the vertical direction. The bent portion 16 is formed at the lower end, and the overlapping portion 17 is formed from the vertical piece 14 to the locking portion 12. In the portion corresponding to the vertical piece in the overlapping portion 17, an attachment hole 17b is formed, and two ribs 17a that are linearly formed in the integrated vertical direction are formed at the overlapping portions.

  Further, prior to forming the overlapped portion as in the above example, as shown in FIG. 11, the opposite facing surfaces of the overlapped portion 17 and the overlapping portion of the overlapped portion 17 are formed on the rough surface 20. It is good to be done. Roughening can be performed by appropriate means such as blasting.

  When roughened, when polymerized, the contact resistance between the surfaces is high, there is no deviation in the surface direction, and high integrity can be obtained.

  In the hanging element 11 configured as described above, since the overlapping portion 17 formed by being folded back by the bending portion 16 is formed in the locking portion 12, the overlapping portion 17 and the portion where it overlaps are formed. The positional relationship is stable, and the shape change of the locking portion 12 can be suppressed. When negative pressure acts on the folded plate roof, a force that extends to the locking portion 12 of the hanging element 11 is applied and the locking portion 12 may be deformed to be extended. Can be prevented and scattering of the folded plate can be suppressed.

  Moreover, when the attachment hole 17 b is formed in the overlapping portion 17, the overlapping portion 17 is tightened with a bolt 22 for fixing to the roof plate attachment fitting 21. For this reason, since the superposition | polymerization state of the superposition | polymerization part 17 is maintained also with the volt | bolt 22, the effect which prevents the shape change of the latching | locking part 12 is high.

  Similarly, in the case where the integrated rib 17a is formed in the overlapping portion in the overlapping portion 17, it is possible to improve the strength and prevent positional deviation in the surface direction between the overlapping portions. Therefore, it is possible to obtain high unity of the polymerized portion.

  When the bent portion 16 is formed on the locking portion 12 and the vertical piece 14, not only the presence of the overlapping portion 17 but also the presence of the bent portion 16 improves rigidity and stabilizes the shape and maintains the shape. Greatly contribute to

  Further, when the opposing surfaces of the overlapping portions are roughened, as described above, the contact resistance between the surfaces is high, there is no deviation in the surface direction, and high integrity can be obtained. A strong form retention capability can be imparted, which contributes to prevention of the scattering of folded plates.

  Furthermore, the reinforcement of the hanging element 11 is not performed by the rib but by the formation of the overlapping portion 17, so that variations in strength are less likely to occur. For this reason, a product with a stable strength can be easily obtained, and the reliability can be increased.

  The above is one form for implementing this invention, This invention is not limited only to the said structure, Other forms can be employ | adopted.

  For example, in addition to providing the bent portion at the front end edge of the fixed piece, it may be provided in the locking portion and the vertical piece to form a suspension having two types of overlapping portions.
