　本発明は、格子状に組み付けられて天井板を吊持する天井板吊持用長尺材に関する。 The present invention relates to a long material for suspending a ceiling plate that is assembled in a lattice shape and suspends the ceiling plate.

　図８，９に示すように、一般的な天井板吊持用長尺材ｆは、上下方向の垂直辺部ｔと、該垂直辺部ｔの上端に形成され、ハンガーｊが固着される係止隆部ｉと、垂直辺部ｔの下端に形成され、天井板ｐの側端部を支持する係止縁部ｇとを備えている。この天井板吊持用長尺材ｆは、格子状に組み付けられて吊り下げられ、係止縁部ｇに天井板ｐの四辺を支持することで室内の天井を構成する。なお、天井板吊持用長尺材ｆは、一般的に、成形加工された帯状金属板により構成されている。 As shown in FIGS. 8 and 9, a general long member f for suspending a ceiling plate is formed on a vertical side portion t in the vertical direction and an upper end of the vertical side portion t, and a hanger j is fixed thereto. It includes a ridge portion i and a locking edge portion g that is formed at the lower end of the vertical side portion t and supports the side end portion of the ceiling board p. The long material f for suspending the ceiling plate is assembled and suspended in a lattice form, and the ceiling of the ceiling plate p is supported by the locking edge portion g to constitute an indoor ceiling. In addition, the long material f for suspending the ceiling plate is generally composed of a band-shaped metal plate that is formed.

　ところで、図９に示すように、天井板吊持用長尺材ｆは、天井板ｐを吊持した状態で、係止縁部ｇの底部が天井に露出する。このため、係止縁部ｇの底部に長手方向の底溝ｈを形成して、天井の意匠に深みを与えるようにしたものが知られている。 By the way, as shown in FIG. 9, the bottom part of the latching edge part g is exposed to the ceiling of the long material f for suspending the ceiling board in a state where the ceiling board p is suspended. For this reason, there has been known a structure in which a bottom groove h in the longitudinal direction is formed at the bottom of the locking edge g to add depth to the ceiling design.

　また、係止縁部ｇに底溝ｈを備えるものには、図１０に示すように、垂直辺部ｔ及び係止隆部ｉを形成する吊持杆ｍと、該吊持杆ｍに組み付けられて係止縁部ｇを形成する係止梁ｎとを備えてなる天井板吊持用長尺材ｆ１が知られている（例えば、特許文献１）。かかる天井板吊持用長尺材ｆ１では、吊持杆ｍは、垂直辺部ｔの下端に、両外方へ延出する水平係合部ｑを備えている。そして、係止梁ｎは、水平係合部ｑの下面に被着される支持下辺部ｒと、支持下辺部ｒの両外側端から折り返して水平係合部ｑの上面を覆うように内方へ延出し、さらに折り返して外方へ延出して積層することにより形成された二重板構造の支持二重辺部ｓとを備え、支持二重辺部ｓと支持下辺部ｒとの間で水平係合部ｑを挟着することで、吊持杆ｍと係止梁ｎが一体的に組み付けられている。 Moreover, as shown in FIG. 10, a suspension rod m that forms a vertical side portion t and a latching ridge portion i and an assembly to the suspension rod m are provided on the engagement edge portion g having a bottom groove h. A long material f1 for suspending a ceiling plate is known that includes a locking beam n that forms a locking edge g (for example, Patent Document 1). In such a ceiling plate hanging long material f1, the hanging rod m is provided with a horizontal engaging portion q extending outwardly at both ends of the vertical side portion t. The locking beam n is inward so as to be folded back from both outer ends of the support lower side r and the support lower side r, which are attached to the lower surface of the horizontal engagement part q, and to cover the upper surface of the horizontal engagement part q. And a support double side s having a double plate structure formed by folding and extending outward and laminating between the support double side s and the support lower side r. By sandwiching the horizontal engagement portion q, the suspension rod m and the locking beam n are assembled together.

　また、従来の天井板吊持用長尺材ｆ，ｆ１には、垂直辺部ｔの上端両脇と下端両脇とに、上下に対向する嵌合溝ｄ，ｅが形成されており、かかる嵌合溝ｄ，ｅに、連結用板片ｚの上下端を夫々係入して垂直辺部ｔに固定することで、天井板吊持用長尺材ｆ，ｆ１を長手方向に連結し得るよう構成されている。ここで、図１１に示すように、吊持杆ｍと係止梁ｎとからなる天井板吊持用長尺材ｆ１では、連結用板片ｚの下端を係入する下部嵌合溝ｅは、前記支持二重辺部ｓの内端と垂直辺部ｔとの間に形成され、その底部は水平係合部ｑの上面によって形成されている。そして、連結用板片ｚを、天井板吊持用長尺材ｆ１に取り付ける場合には、まず、連結用板片ｚの上端を、垂直辺部ｔの上端脇に形成された上部嵌合溝ｄに係入し、連結用板片ｚの下端を支持二重辺部ｓ上に当接した後、上端を支点として下端を垂直辺部ｔ方向へ押し付けて下部嵌合溝ｅへ係入する。 In addition, the conventional long members f and f1 for hanging the ceiling plate are provided with fitting grooves d and e that are vertically opposed to each other at both the upper end and the lower end of the vertical side portion t. The upper and lower ends of the connecting plate pieces z are engaged with the fitting grooves d and e, respectively, and fixed to the vertical side portion t, whereby the ceiling plate hanging long materials f and f1 can be connected in the longitudinal direction. It is configured as follows. Here, as shown in FIG. 11, in the ceiling plate suspension long material f1 composed of the suspension rod m and the locking beam n, the lower fitting groove e for engaging the lower end of the connecting plate piece z is The support double side portion s is formed between the inner end and the vertical side portion t, and the bottom portion is formed by the upper surface of the horizontal engagement portion q. And when attaching the board piece z for connection to the elongate material f1 for ceiling board suspension, first, the upper fitting groove formed in the upper end side of the vertical side part t with the upper end of the board piece z for connection first After engaging the lower end of the connecting plate piece z on the support double side s, the lower end is pressed in the vertical side t direction with the upper end as a fulcrum, and is engaged in the lower fitting groove e. .

　ところで、近年、天井の意匠性向上の要求が高まっており、天井板吊持用長尺材の多くは、底溝が形成された係止縁部を採用している。しかしながら、その一方で、天井板吊持用長尺材は、規格やコスト面での制約が厳しく、天井面に露出する部分に、底溝以上の意匠を付与したものは殆ど存在せず、また、当該露出部分の塗装も白一色で行われている。 Incidentally, in recent years, there has been an increasing demand for improvement in 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.

　本発明は、かかる現状に鑑みてなされたものであり、意匠性が高く、かつ、低コストで製造可能な天井板吊持用長尺材の提供を目的とする。 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 design and can be manufactured at low cost.

　本発明は、上下方向の垂直辺部と、該垂直辺部の上端に形成されてハンガーが固着される係止隆部と、垂直辺部の下端に形成されて天井板の端部を支持する係止縁部とを備えてなり、係止縁部は、垂直辺部の下端から両外方に延出する水平部と、該水平部の両外端から夫々下方に延出する一対の垂下部と、各垂下部の下端から夫々内方に延出する一対の口縁部とを備え、水平部の下底面及び垂下部の内側面によって長手方向の底溝が形成され、両口縁部の間に底溝の開口部が形成されてなるものである天井板吊持用長尺材において、前記係止縁部は、両面が夫々異なる色で塗装された単一の塗装金属板を成形加工してなるものであり、口縁部の下底面には前記塗装金属板の一面側の塗装面が露出し、底溝の開口部から視認される水平部の下底面及び垂下部の内側面には前記塗装金属板の他面側の塗装面が露出していることを特徴とする天井板吊持用長尺材である。 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 The painted surface on one side of the painted metal plate is exposed on the lower bottom surface of the lip, and is below the horizontal portion that is visible from the opening of the bottom groove. The inner surface of the surface and 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.

　かかる構成にあっては、水平部の下底面及び垂下部の内側面によって形成される部分（以下底溝の内側面という）と、口縁部の下底面とが天井面に露出する部分となるが、底溝の内側面と、口縁部の下底面とで色が異なっているため、一色で塗装された従来構成に比べて底溝の深みを強調することができ、これにより意匠性を向上させることができる。
　特に本発明は、両面が夫々異なる色で塗装された単一の塗装金属板をあらかじめ形成し、これを成形加工して、底溝の内側面と、口縁部の下底面とを色分けしているため、低廉に、かつ確実に天井面露出部分を二色に色分けすることができる。すなわち、係止縁部の成形後に色分け塗装をしようとすると、底溝の内側を塗装するのに手間がかかり、塗装コストが増加するとともに、塗装のバラツキが大きくなって不良率も増加する。また、塗装金属板の片面を二色で塗装する場合にも、塗装コストがかかり、また、二色塗装の境界部分に塗装ムラが生じ易い。これらと比較して、本構成では、予め両面を異なる色で塗装した塗装金属板を用いることで、塗装コストを抑えることができ、また、塗装の仕上がりも良好となる。 In such a configuration, the portion formed by the lower bottom surface of the horizontal portion and the inner side surface of the hanging portion (hereinafter referred to as the inner surface of the bottom groove) and the lower bottom surface of the mouth edge portion are exposed to the ceiling surface. However, because the color is different between the inner surface of the bottom groove and the lower bottom surface of the lip, the depth of the bottom groove can be emphasized compared to the conventional configuration painted in one color, thereby improving the design. Can be improved.
In particular, the present invention preliminarily forms a single painted metal plate whose both surfaces are painted in different colors, and this is molded to color-code the inner surface of the bottom groove and the lower bottom surface of the mouth edge. Therefore, the exposed portion of the ceiling surface can be color-coded in two colors at low cost. 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.

　また、本発明にあって、前記塗装金属板は、両面が夫々濃度の異なる同色系統の色で塗装され、薄い方の色で塗装された側を、口縁部の下底面に露出させている構成も提案される。底溝の内側面は、底溝の両側部に比して塗装面に当たる光量が少なく、同じ塗装色でも光量の差異によるコントラストが生じているが、かかる構成のように、底溝の内側を濃色で、口縁部の下底面を薄色で塗装すれば、光量の差異と、色の濃度の差異との相乗効果によって、底溝の内側面と両側部との間に、高く、自然なコントラストを生じさせることができ、これにより底溝部分の深みを好適に強調し、高い意匠性を発揮させることが可能となる。 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 surface of the bottom groove has less light hitting the painted 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 lower bottom surface of the lip is painted lightly in color, the natural difference between the inner surface and both sides of the bottom groove is high and natural due to the synergistic effect of the difference in light quantity 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.

　また、本発明にあって、前記垂直辺部と前記係止隆部とを形成するとともに、垂直辺部の下端から両外方へ延出する水平係合部とを具備してなる断面逆Ｔ字状の吊持杆と、吊持杆の水平係合部下面に被着される支持下辺部と、該支持下辺部の両外側端から折り返して水平係合部の上面を覆うように内方へ延出し、さらに折り返して外方へ延出して積層することにより形成された二重板構造の支持二重辺部とによって前記水平部を構成するとともに、各支持二重辺部の外端から下方へ延出して垂下部を形成し、さらに、各垂下部の下端から夫々内方に延出して口縁部を形成する係止梁とを組み付けてなるものであり、前記吊持杆が非塗装金属板で構成され、前記係止梁が前記単一の塗装金属板で構成されることが提案される。かかる構成にあっては、天井面露出部分を構成する係止縁部を塗装金属板で構成し、それ以外の部分を非塗装金属板で構成しているため、比較的高価な塗装金属板の使用量を抑制し、材料費を低減することが可能となる。 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.

　また、上記のように、吊持杆と係止梁を組み付けてなる構成にあっては、吊持杆の係止隆部が断面環状を成し、その下面に長手方向に沿って形成された上部嵌合溝と、前記支持二重辺部の内端と垂直辺部との間に形成された、水平係合部を底部とする下部嵌合溝とを備えてなり、上部嵌合溝と下部嵌合溝とに、垂直辺部の側面に係合される連結用板片の上下端部を嵌合させるようにしたものであって、水平係合部及び支持下辺部が支持二重辺部の内側で上方に膨隆しており、水平係合部は、支持二重辺部に覆われる部分よりも、下部嵌合溝の底部を形成する部分が上方に位置しており、口縁部の下底面に前記塗装金属板の一面側の塗装面を露出するとともに、上方へ膨隆した支持下辺部の下底面に他面側の塗装面を、底溝の開口部から視認可能に露出している構成が提案される。かかる構成にあっては、下部嵌合溝の深さを、支持二重辺部の厚みに比して浅くすることができるため、連結用板片を下部嵌合溝に係入させ易くなる。 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, and the painted surface on the other side is visible from the bottom groove opening on the bottom surface of the bottom side of the support that bulges upward. Configuration is proposed which is exposed to the capacity. 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.

　また、本発明にあって、前記垂直辺部と、前記係止隆部と、前記係止縁部とが、前記単一の塗装金属板のみによって構成されることも提案される。かかる構成にあっては、天井板吊持用長尺材を複数枚の金属板で構成する場合に比べて、金属板相互を組み付ける作業が不要となる分、簡単に製造することができる。 Further, in the present invention, it is also proposed that the vertical side portion, the locking ridge portion, and the locking edge portion are constituted only by 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.

　以上に述べたように、本発明は、天井面に露出することとなる底溝の内側面と、口縁部の下底面とを異なった色としているため、一色で塗装された従来構成に比べて底溝の深みを強調することができ、これにより意匠性を向上させることができる。
　また、両面が夫々異なる色で塗装された単一の塗装金属板をあらかじめ形成し、これを成形加工して、底溝の内側面と、口縁部の下底面とを色分けしているため、低廉かつ確実に天井面の露出部分を二色に色分けすることができ、しかも二色塗装の境界部分に塗装ムラを生じさせること無く、良好な塗装の仕上がりを確保することができ、塗装コストを抑えることができる。 As described above, the present invention uses a different color for the inner surface of the bottom groove that will be exposed to the ceiling surface and the lower bottom surface of the mouth edge portion, so compared to the conventional configuration painted in one color. Thus, the depth of the bottom groove can be emphasized, and thereby the design can be improved.
In addition, because a single painted metal plate with both sides painted in different colors is formed in advance, and this is molded, the inner surface of the bottom groove and the lower bottom surface of the lip are color-coded, Inexpensive and reliable, the exposed part of the ceiling surface can be color-coded in two colors, and the finish of the two-color coating can be ensured without causing uneven coating, resulting in a good painting cost. Can be suppressed.

　本実施例の天井板吊持用長尺材１は、一枚の帯状塗装鋼板３０を、図１に示す断面形状の長尺材となるように、ロール成形やプレス成形することによって製造される。かかる成形加工の方法は、従来構成と同様であるため、詳細な説明は省略する。 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.

　本実施例の天井板吊持用長尺材１は、両面が異なる色で塗装された単一の塗装鋼板３０を成形してなるものである。天井板吊持用長尺材１は、その使用状態にあって、図２に示すように、係止縁部４の底部のみが天井面に露出して下方から視認可能となる。この露出部分は、水平部９の下底面及び垂下部１０の内側面とからなる底溝内側面Ｘと、口縁部１１の下底面Ｙとで構成されるが、底溝内側面Ｘと口縁部下底面Ｙとでは、塗装鋼板３０両面の異なる塗装面が露出している。このため、本実施例の天井板吊持用長尺材１は、天井を見上げた時に、開口部７から覗く底溝内側面Ｘと、開口部７の両脇に位置する口縁部下底面Ｙとが二色に色分けされて視認される。 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 surface X composed of a lower bottom surface of the horizontal portion 9 and an inner side surface of the hanging portion 10 and a lower bottom surface Y of the mouth edge portion 11. On the bottom bottom surface Y of the edge, different painted surfaces of both surfaces of the coated steel plate 30 are exposed.

Are visually recognized in two colors.

　本実施例では、塗装鋼板３０の両面は、夫々濃度の異なる同系統の色で塗装される。そして、口縁部下底面Ｙ、すなわち口縁部１１の下底面には濃度の薄い方が露出し、底溝内側面Ｘ、すなわち水平部９の下底面と垂下部１０の内側面に濃度の濃い方が露出するよう構成されている。濃い色と薄い色との具体的な組合せとしては、黄色系統であればクリーム色（薄）と芥子色（濃）、青系統であれば水色（薄）と紺色（濃）、緑系統であれば草色（薄）と深緑色（濃）などが挙げられる。 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 lower bottom surface Y of the lip portion, that is, the lower bottom surface of the lip portion 11, and the concentration is high on the inner surface X of the bottom groove, that is, the lower bottom surface of the horizontal portion 9 and the inner surface of the drooping portion 10. 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. Examples include grass color (light) and dark green (dark).

　このように、本実施例の天井板吊持用長尺材１は、天井を構成した状態で、天井面に露出する底溝内側面Ｘと口縁部下底面Ｙとが夫々異なる色で塗装されるため、底溝６と、その両側の色の違いによって底溝６の深みを強調し、意匠性を向上させることができる。 Thus, the long material 1 for suspending the ceiling board of the present embodiment is painted in different colors on the inner surface X of the bottom groove exposed on the ceiling surface and the lower bottom surface Y of the lip portion in a state where the ceiling is formed. Therefore, the depth of the bottom groove 6 can be emphasized by the difference in color between the bottom groove 6 and its both sides, and the design can be improved.

　特に、本実施例では、塗装鋼板３０の両面が夫々濃度の異なる同系統の色で塗装され、底溝内側面Ｘを構成する面に塗装色の濃い方が露出しているから、底溝６の内外で、光量の差異と塗装色の濃度の差異とが相乗することで自然で明瞭なコントラストが生じ、優れた意匠性を発揮している。 In particular, in this embodiment, both surfaces of the coated steel plate 30 are coated with the same color having different concentrations, and the darker one is exposed on the surface constituting the inner surface X of the bottom groove. The difference in the amount of light and the difference in the concentration of the paint color are synergistically generated inside and outside the lens, and a natural and clear contrast is produced, and an excellent design property is exhibited.

　そして、本実施例の天井板吊持用長尺材１は、両面が異なる色で塗装された塗装鋼板３０を成形してなるものであるから、鋼板３０の成形後に天井板吊持用長尺材１を塗装する必要がなく、極めて簡単に、かつ良好な仕上がりで天井面露出部分を二色に色分けすることができる。特に、本実施例では、垂直辺部２、係止隆部３及び係止縁部４の全てが一枚の塗装鋼板３０で構成されているため、複数の金属板を組み付けたりすることなく、簡単に製造できるという利点がある。 And since the long material 1 for ceiling board suspension of a present Example forms the coated steel plate 30 coated in the color from which both surfaces differ, the ceiling plate suspension long material is formed after the steel plate 30 shaping | molding. There is no need to paint the material 1, and the exposed portion of the ceiling surface can be color-coded in two colors very easily and with a good finish. In particular, in the present embodiment, since all of the vertical side portion 2, the locking ridge 3 and the locking edge portion 4 are formed of a single coated steel plate 30, without assembling a plurality of metal plates, There is an advantage that it can be easily manufactured.

　実施例２の天井板吊持用長尺材１ａは、図３に示すように、実施例１同様に、上下方向の垂直辺部２と、該垂直辺部２の上端に形成される係止隆部３と、該垂直辺部２の下端に形成される係止縁部４とからなる。ここで、天井板吊持用長尺材１ａは、垂直辺部２と係止隆部３を形成する吊持杆２０と、該吊持杆２０に組み付けられて係止縁部４を形成する係止梁２１とを備えてなる。 As shown in FIG. 3, the long material 1 a for suspending a ceiling board according to the second embodiment has a vertical side 2 in the vertical direction and a latch formed at the upper end of the vertical side 2 as in the first embodiment. It consists of a ridge 3 and a locking edge 4 formed at the lower end of the vertical side 2. Here, the long material 1a for suspending the ceiling plate is formed with a suspension rod 20 that forms the vertical side portion 2 and the latching ridge 3, and the latching edge portion 4 that is assembled to the suspension rod 20. The locking beam 21 is provided.

　吊持杆２０は、一枚の帯状の非塗装鋼板（非塗装金属板）３１を成形してなるものであり、図３に示すように、垂直辺部２及び係止隆部３に加えて、係止梁２１を組み付けるための水平係合部２２，２２を備えている。具体的には、非塗装鋼板３１の中央部分を上部で折り返して二枚重ね合わせ状にすることによって上下方向の垂直辺部２が形成され、また、上部の折返し部分を断面矩形環状に膨隆させることにより係止隆部３が形成されている。そして、垂直辺部２の下端で、Ｔ字状となるように二枚の非塗装鋼板３１を夫々外方に９０°屈曲させることにより、水平係合部２２，２２が形成されている。 The suspension rod 20 is formed by forming a single strip-shaped non-painted steel plate (non-painted metal plate) 31 and, in addition to the vertical side 2 and the locking ridge 3, as shown in FIG. ,

Horizontal engagement portions

Specifically, the vertical side 2 in the vertical direction is formed by folding the central portion of the unpainted steel sheet 31 at the upper part to form two sheets, and the upper folded part is bulged into a rectangular cross section. A locking ridge 3 is formed. Then, at the lower end of the vertical side portion 2, the two non-painted steel plates 31 are bent outwardly by 90 ° so as to form a T shape, thereby forming the horizontal engaging

portions

22, 22.

　係止梁２１は、一枚の帯状の塗装鋼板３０を成形してなるものであり、図３に示すように、長手方向の底溝６が下部中央に開口した断面略矩形状をなしている。この係止梁２１は、吊持杆２０の水平係合部２２，２２に組み付けられて係止縁部４を形成するものであり、水平係合部２２を上下に狭着して水平部９を形成することとなる支持下辺部２３及び支持二重辺部２４を備えている。 The locking beam 21 is formed by forming a single strip-shaped coated steel plate 30 and has a substantially rectangular cross section in which the bottom groove 6 in the longitudinal direction is opened in the lower center as shown in FIG. . This locking beam 21 is assembled to the horizontal engaging

portions

In addition, the both-ends edges 12 and 12 of the coated steel plate 30 are folded back to the upper side of the mouth edge part 11 so that they cannot be seen from below.

　そして、上述した吊持杆２０と係止梁２１とは、吊持杆２０の水平係合部２２，２２を、その下面に被着される支持下辺部２３と各上面を夫々覆う支持二重辺部２４，２４とによりかしめて狭着することによって、一体化されている。これにより、天井板吊持用長尺材１ａが形成されている。 The suspension rod 20 and the locking beam 21 described above are the support doubles that respectively cover the

horizontal engagement portions

22 and 22 of the suspension rod 20, the support lower side portion 23 attached to the lower surface thereof, and the respective upper surfaces. They are integrated by caulking tightly with the

side portions

24, 24. Thereby, the long material 1a for ceiling plate suspension is formed.

　本実施例の天井板吊持用長尺材１ａは、帯状の非塗装鋼板にロール成形加工を施して吊持杆２０を製造し、さらに、帯状の塗装鋼板を、ロール成形加工によって段階的に係止梁２１の形状に成形していき、最終的に、吊持杆２０の水平係合部２２，２２にかしめて狭着することで係止梁２１を成形する。なお、この天井板吊持用長尺材１ａの成形加工方法は、上記特許文献１に記載の従来構成と同様に実施できるため、詳細は省略する。 The long material 1a for suspending a ceiling plate of the present embodiment produces a suspension rod 20 by subjecting a strip-shaped non-coated steel plate to roll forming, and further steps the strip-shaped coated steel plate by roll forming. The locking beam 21 is formed into the shape of the locking beam 21, and finally, the locking beam 21 is formed by caulking to the

horizontal engagement portions

22 and 22 of the suspension rod 20 and narrowing. In addition, since the shaping | molding processing method of this long material 1a for ceiling board suspension can be implemented similarly to the conventional structure of the said patent document 1, it abbreviate | omits for details.

　上記のように、本実施例の天井板吊持用長尺材１ａは、一枚の非塗装鋼板３１を成形してなる吊持杆２０と、一枚の塗装鋼板３０を成形してなる係止梁２１とを組み付けてなる。ここで、係止梁２１を構成する塗装鋼板３０は、その両面が異なる色で塗装されたものであり、図４に示すように、実施例１と同様に、天井板吊持用長尺材１ａは、天井面に露出する底溝内側面Ｘと口縁部下底面Ｙとが二色に色分けされて視認される。したがって、本実施例にあっても、底溝６と、その両側の色の違いによって底溝６の深みを強調し、意匠性を向上させることができる。 As described above, the long material 1a for suspending a ceiling plate according to the present embodiment includes a suspension rod 20 formed by forming a single non-coated steel plate 31 and a single formed steel plate 30. It is assembled with the stop beam 21. Here, the coated steel plate 30 constituting the locking beam 21 is coated with different colors on both sides, and as shown in FIG. In 1a, the bottom groove inner side surface X exposed on the ceiling surface and the lip portion lower bottom surface Y 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.

　また、本実施例にあっても、両面が異なる色で塗装された塗装鋼板３０によって係止縁部４を形成することで、簡単に、かつ良好な仕上がりで天井面に露出する部分を二色に色分けできるという利点がある。特に、本実施例では、垂直辺部２や係止隆部３を非塗装鋼板３１で形成することで、比較的高価な塗装鋼板３０の使用量を減らすことができ、実施例１の構成に比べて材料費を抑えることができるという利点がある。 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.

　また、実施例２の天井板吊持用長尺材１ａでは、図５に示すように、垂直辺部２の上端両脇位置に上部嵌合溝５，５が形成されるとともに、垂直辺部２の下端両脇位置に下部嵌合溝８，８が形成されており、従来構成同様に、かかる嵌合溝５，８に、連結用板片ｚを係入して垂直辺部２の側面に係合させることによって、天井板吊持用長尺材１ａを長手方向に連結し得るよう構成されている。 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.

　具体的には、上部嵌合溝５，５は、図５（ａ）に示すように、垂直辺部２の上端両脇で、係止隆部３の下面を長手方向に沿って上方へ窪ませることによって設けられている。 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.

　一方、下部嵌合溝８，８は、垂直辺部２の下端両脇で、水平係合部２２，２２を底部として形成される。すなわち、本実施例では、図５（ｂ）に示すように、各支持二重辺部２４，２４は、その内端が垂直辺部２から離間して形成されており、水平係合部２２，２２は、支持二重辺部２４の内端よりも内側で、支持二重辺部２４に覆われずに上面が露出している。そして、水平係合部２２，２２は、かかる露出部分において、長手方向に沿って上方に突出し、支持二重辺部２４の内端に接するリブ部２５，２５が曲成されている。そして、このリブ部２５は、垂直辺部２の下端から外方に離間しており、かかるリブ部２５と垂直辺部２との間に、水平係合部２２を底部とする下部嵌合溝８が形成される。 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.

　ここで、図５（ｂ）に示すように、水平係合部２２及び支持下辺部２３は、支持二重辺部２４の内端よりも内方において、相互に密着した状態で、塗装鋼板３０の厚み分だけ上方に膨隆している。かかる構成によれば、下部嵌合溝８の底面の高さが、外方に位置する支持二重辺部２４の上面に近づくことで、下部嵌合溝８の深さが塗装鋼板３０一枚分だけ浅くなる。 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.

　そして、本実施例では、このように下部嵌合溝８を浅くなることにより、連結用板片ｚを下部嵌合溝８に容易に係入可能となる。図１１の従来の天井板吊持用長尺材ｆ１と比較して説明すると、吊持杆ｍと係止梁ｎを備えた従来構成では、図６（ａ）に示すように、水平係合部ｑの上面は、支持二重辺部ｓに覆われる部分と、下部嵌合溝ｅの底部を形成する部分とが略同じ高さに位置しており、下部嵌合溝ｅの深さｗ１は、支持二重辺部ｓの厚み、すなわち塗装鋼板３０二枚分の深さとなっている。このように、かかる従来構成では、下部嵌合溝ｅの底部に対して、支持二重辺部ｓの上面が比較的高い位置にあるため、連結用板片ｚの下端を支持二重辺部ｓ上に当接し、上端を支点として当該下端を垂直辺部ｔ方向へ押し付けた際に、連結用板片ｚの下端がつかえやすく、当該下端を下部嵌合溝ｅへ係入するのに手間取ることが多い。連結用板片ｚの上下寸法を短くすれば、下端がつかえ難くはなるが、下部嵌合溝ｅに係入した際の遊びが大きくなり不安定となる。 In this embodiment, the connecting plate piece z can be easily engaged with the lower fitting groove 8 by making the lower fitting groove 8 shallow. 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.

　これに対して、本実施例では、図６（ｂ）に示すように、水平係合部２２の膨隆によって、水平係合部２２の上面は、支持二重辺部２４に覆われる部分よりも、下部嵌合溝８の底部を形成する部分が、塗装鋼板３０一枚分だけ高い位置にあり、これにより、下部嵌合溝８の深さｗ２は、支持二重辺部２４よりも薄い、塗装鋼板３０一枚分の深さとなっている。このように、本実施例では、下部嵌合溝８の底部に対して、支持二重辺部２４の上面が比較的低い位置にあるため、連結用板片ｚの下端を支持二重辺部２４上に当接して下部嵌合溝ｅへ係入する際に、連結用板片ｚの下端を殆どつかえさせずに簡単に係入させることができ、また、下部嵌合溝８に係入した時の遊びも小さくなる。 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.

　また、本実施例では、水平係合部２２を膨隆させるだけでなく、支持下辺部ｒを、支持二重辺部２４の内側で水平係合部２２に倣うように上方に膨隆させて、水平係合部２２の下面に密着させているから、図１１の従来構成と同等の強度で、係止梁２１を吊持杆２０に組み付けることができ、水平係合部２２の膨隆によって強度不足が生じることもない。 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.

　なお、本発明の天井板吊持用長尺材は、上記実施例の形態に限らず本発明の要旨を逸脱しない範囲内において種々変更を加えることができる。例えば、上記実施例１，２では、垂直辺部の上端両脇と下端両脇に、連結用板片を係合する嵌合溝が形成されているが、本発明は、図７に示すような、嵌合溝を具備しない天井板吊持用長尺材１ｂにも適用できる。 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.
