  By the way, in recent years, there has been an increasing demand for improving the design of the ceiling, and many of the long materials for suspending the ceiling plate employ a locking edge portion in which a bottom groove is formed. However, on the other hand, long materials for hanging ceiling panels are severely limited in terms of standards and costs, and there are almost no products with a design that is more than the bottom groove on the exposed part of the ceiling surface. The exposed portion is also painted in white.

  The present invention has been made in view of the present situation, and an object of the present invention is to provide a long material for hanging a ceiling plate that has high designability and can be manufactured at low cost.

The present invention supports vertical edges in the vertical direction, locking ridges formed at the upper ends of the vertical edges to which hangers are secured, and ends of the ceiling boards formed at the lower ends of the vertical edges. The locking edge portion includes a horizontal portion that extends outward from the lower end of the vertical side portion, and a pair of hanging portions that respectively extend downward from both outer ends of the horizontal portion. And a pair of mouth edges extending inwardly from the lower end of each hanging part, and a bottom groove in the longitudinal direction is formed by the lower bottom face of the horizontal part and the inner side face of the hanging part. In the long material for hanging the ceiling plate, in which the opening of the bottom groove is formed between, the locking edge portion is formed of a single painted metal plate coated with different colors on both sides processed are those comprising, on the bottom surface of the rim is exposed coated surface of one side of the coated metal plate, the lower base of the horizontal portion to be seen through a portion of the bottom groove And the inner surface of the hanging portion be a ceiling board hanging-held elongated member, characterized in that the coated surface of the other surface side of the coated metal plate is exposed.

  In such a configuration, the inner side portion of the bottom groove formed by the lower bottom surface of the horizontal portion and the inner side surface of the hanging portion, and both side portions of the bottom groove formed by the lower bottom surface of the mouth edge portion are exposed to the ceiling surface. However, since the color is different between the inner side of the bottom groove and both sides of the bottom groove, the depth of the bottom groove can be emphasized compared to the conventional configuration painted in one color, Designability can be improved. In the present invention, because the inner portion and both side portions of the bottom groove are color-coded according to the difference in the paint color on both sides of the painted metal plate, the exposed portion of the ceiling surface can be color-coded in a low-cost and surely manner. Can do. That is, when color-coded coating is performed after the locking edge portion is formed, it takes time to paint the inside of the bottom groove, the coating cost increases, the coating variation increases, and the defect rate also increases. Also, when one side of the coated metal plate is painted with two colors, the coating cost is high, and coating unevenness is likely to occur at the boundary between the two colors. Compared with these, in this structure, the coating cost can be restrained by using the coating metal plate which coated both surfaces with a different color beforehand, and the finish of coating also becomes favorable.

  Further, in the present invention, the coated metal plate is coated with a color of the same color system having different concentrations on both sides, and the side coated with the lighter color is exposed on the lower bottom surface of the mouth portion. A configuration is also proposed. The inner part of the bottom groove has less light hitting the paint surface than both sides of the bottom groove, and even with the same paint color, there is a contrast due to the difference in the amount of light. If the bottom surface of the lip is painted lightly in color, there is a synergistic effect between the difference in the amount of light and the difference in color density. Contrast can be generated, and thereby the depth of the bottom groove portion can be favorably enhanced and high design properties can be exhibited.

  Further, in the present invention, the cross-section inverted T that forms the vertical side portion and the locking ridge portion and includes a horizontal engaging portion that extends outward from the lower end of the vertical side portion. A letter-shaped suspension rod, a support lower side portion attached to the lower surface of the horizontal engagement portion of the suspension rod, and an inner side so as to cover the upper surface of the horizontal engagement portion by folding back from both outer ends of the support lower side portion The horizontal portion is constituted by a double-sided support double side portion formed by extending and laminating and laminating to the outside, and from the outer end of each support double side It is formed by assembling a hanging beam that extends downward to form a hanging portion, and further extends inwardly from the lower end of each hanging portion to form a mouth edge portion. It is proposed that it is composed of a painted metal plate and that the locking beam is composed of the single painted metal plate. In such a configuration, the engaging edge portion constituting the exposed portion of the ceiling surface is made of a painted metal plate, and the other portions are made of a non-painted metal plate. The amount used can be suppressed, and the material cost can be reduced.

Further, as described above, in the configuration in which the suspension rod and the locking beam are assembled, the locking ridge portion of the suspension rod has an annular cross section and is formed on the lower surface along the longitudinal direction. An upper fitting groove, and a lower fitting groove formed between the inner end and the vertical side of the supporting double side portion and having a horizontal engaging portion as a bottom portion. The upper and lower end portions of the connecting plate piece engaged with the side surface of the vertical side portion are fitted to the lower fitting groove, and the horizontal engagement portion and the support lower side portion are supported double sides. The portion that forms the bottom portion of the lower fitting groove is located above the portion that is covered with the supporting double side portion, and the horizontal engaging portion is located above the lip portion. The painted surface on one side of the painted metal plate is exposed on the bottom surface of the bottom plate, and the painted surface on the other side on the bottom surface of the bottom side of the support that bulges upward is approved from the bottom groove opening. Configuration is proposed which is exposed to. In such a configuration, since the depth of the lower fitting groove can be made smaller than the thickness of the supporting double side portion, the connecting plate piece is easily engaged with the lower fitting groove.

  In the present invention, it is also proposed that the vertical side portion, the locking ridge, and the locking edge are constituted by only the single painted metal plate. In such a configuration, as compared with the case where the long material for suspending the ceiling plate is formed of a plurality of metal plates, the work of assembling the metal plates can be easily manufactured.

  As described above, according to the long material for suspending a ceiling board of the present invention, there is an advantage that high designability can be realized at a low cost as compared with the conventional configuration.

The long material 1 for suspending a ceiling plate has the same shape as the long material f for suspending a ceiling plate shown in FIG. Specifically, the long material 1 for suspending the ceiling plate of the present embodiment is formed by forming a single strip-shaped coated steel plate (painted metal plate) 30, and the vertical side portion 2 is formed of a coated steel plate. 30 is formed so that both sides with respect to the center line in the longitudinal direction are partially back-to-back, and has a two-plate shape in the vertical direction. The locking ridges 3 are formed by extending the upper ends of the two plates constituting the vertical side 2 and bending the coated steel plate 30 into an annular cross section. Then, upper locking grooves 5 and 5 for engaging the connecting plate pieces z are formed downward in the locking ridge 3 at both upper end sides of the vertical side 2.

  The locking edge portion 4 has a rectangular cross section in which a bottom groove 6 in the longitudinal direction opens at the center of the lower portion. Specifically, the locking edge portion 4 includes a horizontal portion 9 formed by bending the double-layered coated steel plates 30 90 ° in opposite directions at the lower end of the vertical side portion 2 and extending outward, and a horizontal portion. 9, the hanging steel plates 30 are bent 90 ° at both outer ends and extended downward, and the coated steel plates 30 are bent 90 ° at the lower ends of the hanging portions 10, 10 inward. The lip portions 11 and 11 are extended. And each edge part 11 and 11 hits the edge part of the coated steel plate 30, and the opening part 7 of the bottom groove 6 is formed between the inner ends of both the edge parts 11 and 11. FIG. Moreover, each edge 12, 12 of the coated steel plate 30 is folded back to the upper surface side at the inner end of each mouth edge portion 11, and is not visible from below. Further, lower fitting grooves 8 and 8 for engaging the connecting plate pieces z are formed upward in the horizontal portion 9 at both sides of the lower end of the vertical side portion 2.

  The long material 1 for suspending the ceiling plate of the present embodiment is manufactured by roll-forming or press-forming one strip-like coated steel plate 30 so as to be a long material having a cross-sectional shape shown in FIG. . Since the forming method is the same as that of the conventional configuration, detailed description thereof is omitted.

  The long material 1 for suspending a ceiling board according to the present embodiment is formed by molding a single coated steel sheet 30 coated on both sides with different colors. As shown in FIG. 2, the long member 1 for suspending the ceiling plate is exposed to the ceiling surface and is visible from below, as shown in FIG. 2. The exposed portion is composed of a bottom groove inner side portion X composed of the lower bottom surface of the horizontal portion 9 and the inner side surface of the drooping portion 10, and a bottom groove both side portions Y composed of the lower bottom surface of the mouth edge portion 11, In the groove inner part X and the bottom groove both side parts Y, different painted surfaces of both surfaces of the coated steel sheet 30 are exposed. For this reason, the long material 1 for suspending the ceiling plate of the present embodiment has a bottom groove inner side portion X viewed from the opening portion 7 and a bottom groove both side portions Y located on both sides of the opening portion 7 when looking up at the ceiling. Are visually recognized in two colors.

  In this embodiment, both surfaces of the coated steel sheet 30 are painted with the same color having different concentrations. Then, the lighter side is exposed on the bottom groove both sides Y, that is, the lower bottom surface of the lip portion 11, and the bottom groove inner portion X, that is, the lower bottom surface of the horizontal portion 9 and the inner surface of the drooping portion 10 are dense. It is configured so that one is exposed. Specific combinations of dark and light colors are cream (light) and aubergine (dark) for the yellow system, and light blue (light), amber (dark), and green system for the blue system.

In 1a, the bottom groove inner side portion X and the bottom groove both side portions Y exposed on the ceiling surface are visually recognized in two colors. Therefore, even in the present embodiment, the depth of the bottom groove 6 can be emphasized by the difference in color between the bottom groove 6 and both sides thereof, and the design can be improved.

  Further, even in the present embodiment, by forming the engaging edge portion 4 with the coated steel plate 30 coated with different colors on both sides, the two portions exposed to the ceiling surface easily and with a good finish can be obtained. There is an advantage that it can be color-coded. In particular, in this embodiment, by forming the vertical side 2 and the locking ridge 3 with the non-coated steel plate 31, the amount of use of the relatively expensive coated steel plate 30 can be reduced. There is an advantage that the material cost can be suppressed compared to the above.

  Moreover, in the long material 1a for ceiling board suspension of Example 2, as shown in FIG. 5, while the upper fitting groove | channels 5 and 5 are formed in the upper end both sides position of the vertical side part 2, a vertical side part is formed. Lower fitting grooves 8 and 8 are formed at positions on both sides of the lower end of 2, and the connecting plate piece z is inserted into the fitting grooves 5 and 8 in the same manner as in the conventional configuration, and the side surface of the vertical side portion 2. By being engaged with each other, the long material 1a for suspending the ceiling plate can be connected in the longitudinal direction.

  Specifically, as shown in FIG. 5A, the upper fitting grooves 5, 5 are recessed upward along the longitudinal direction on the lower surface of the locking ridge 3 on both sides of the upper end of the vertical side 2. It is provided by not.

  On the other hand, the lower fitting grooves 8 and 8 are formed on both sides of the lower end of the vertical side portion 2 with the horizontal engaging portions 22 and 22 as bottom portions. That is, in this embodiment, as shown in FIG. 5B, the support double side portions 24, 24 are formed so that the inner ends thereof are separated from the vertical side portion 2, and the horizontal engagement portion 22. , 22 are located on the inner side of the inner end of the support double side 24 and are not covered by the support double side 24 and the upper surface is exposed. In the exposed portions, the horizontal engaging portions 22 and 22 protrude upward along the longitudinal direction, and rib portions 25 and 25 that contact the inner end of the support double side portion 24 are bent. The rib portion 25 is spaced outward from the lower end of the vertical side portion 2, and a lower fitting groove having the horizontal engagement portion 22 as a bottom portion between the rib portion 25 and the vertical side portion 2. 8 is formed.

  Here, as shown in FIG. 5B, the horizontal engagement portion 22 and the support lower side portion 23 are in close contact with each other at the inner side of the inner end of the support double side portion 24, and the coated steel plate 30. It bulges upward by the thickness of. According to such a configuration, the depth of the lower fitting groove 8 is one sheet of the coated steel plate 30 because the height of the bottom surface of the lower fitting groove 8 approaches the upper surface of the support double side portion 24 located outward. It becomes shallower than that.

  In this embodiment, the lower fitting groove 8 becomes shallow as described above, whereby the connecting plate piece z can be easily engaged with the lower fitting groove 8. When compared with the conventional long material f1 for ceiling plate suspension of FIG. 11, in the conventional configuration including the suspension rod m and the locking beam n, as shown in FIG. In the upper surface of the part q, the part covered with the support double side part s and the part forming the bottom part of the lower fitting groove e are located at substantially the same height, and the depth w1 of the lower fitting groove e Is the thickness of the supporting double side portion s, that is, the depth of two coated steel plates 30. Thus, in such a conventional configuration, since the upper surface of the support double side s is at a relatively high position with respect to the bottom of the lower fitting groove e, the lower end of the connecting plate piece z is supported by the support double side. When the lower end is pressed in the vertical side t direction with the upper end as a fulcrum, the lower end of the connecting plate piece z is easily grasped, and it takes time to engage the lower end into the lower fitting groove e. There are many cases. If the vertical dimension of the connecting plate piece z is shortened, it is difficult to grasp the lower end, but the play when engaged in the lower fitting groove e becomes large and becomes unstable.

  On the other hand, in this embodiment, as shown in FIG. 6B, the upper surface of the horizontal engagement portion 22 is more than the portion covered by the support double side portion 24 due to the bulging of the horizontal engagement portion 22. The portion that forms the bottom of the lower fitting groove 8 is at a position that is higher by one sheet of the coated steel plate 30, whereby the depth w2 of the lower fitting groove 8 is thinner than the support double side 24. It is the depth of one coated steel plate 30. Thus, in this embodiment, since the upper surface of the supporting double side 24 is located at a relatively low position with respect to the bottom of the lower fitting groove 8, the lower end of the connecting plate piece z is supported by the supporting double side. 24, when engaging with the lower fitting groove e, it is possible to easily engage with the lower end of the connecting plate piece z, and to engage with the lower fitting groove 8. The play when you do it also becomes smaller.

  Further, in this embodiment, not only the horizontal engagement portion 22 is bulged, but also the support lower side portion r is bulged upward so as to follow the horizontal engagement portion 22 inside the support double side portion 24, thereby Since it is in close contact with the lower surface of the engaging portion 22, the locking beam 21 can be assembled to the suspension rod 20 with the same strength as that of the conventional configuration in FIG. It does not occur.

  The long material for suspending the ceiling board of the present invention is not limited to the embodiment described above, and various modifications can be made without departing from the gist of the present invention. For example, in the first and second embodiments, the fitting grooves for engaging the connecting plate pieces are formed on both the upper and lower sides of the vertical side portion, but the present invention is shown in FIG. In addition, the present invention can also be applied to a long material 1b for suspending a ceiling plate that does not have a fitting groove.
