Description

[Technical field]

[0001] The present invention uses simple members (main body and holding member) and can be installed very easily. For interior and exterior use Regarding board materials. [Background technology]

[0002] A roof structure in which a tight frame is fixed to a cross beam (structure) made of a steel frame and folded plates are laid on the tight frame is widely known. In this type of roof structure, the folded plates are laid in a direction perpendicular to the longitudinal direction of the cross beams. Also, because the cross beams are constructed at intervals of 3 to 5 meters due to the shape of the roof material, etc., space is required to set up scaffolding inside the room when installing the tight frame, laying the roof material, etc. In this case, the ceiling structure is generally constructed separately from the roof structure. Therefore, if you try to install a ceiling in a gymnasium or the like after the roof has been installed, scaffolding is required just for the ceiling installation.

[0003] For example, Patent Document 1 proposes a structure in which a wall material such as a ceiling material is erected between C-shaped steel (channel steel with a lip). Moreover, Patent Document 2 proposes a structure in which a ceiling folded plate body and a folded plate roof body are laid on a beam. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4764375 [Patent Document 2] Patent No. 5973749 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned Patent Document 1, the wall material used is a dedicated material for ceilings, and it is difficult to use it for anything other than ceilings. Specifically, one of the left and right edges of the face plate is attached so as to cover the C-shaped steel, but the other is attached to the lip of the lower flange of the C-shaped steel, so it is not possible to form a continuous exterior surface. In addition, the above-mentioned Patent Document 2 does not propose a single unit that can be used for both interior and exterior purposes, as it originally involves laying a ceiling folded plate body and a folded plate roof body that have different shapes. As described above, the above-mentioned Patent Documents 1 and 2 cannot be used for both roof structures and ceiling structures, and therefore have various problems such as the above-mentioned product management.

[0006] Therefore, the present invention uses simple members (main body and holding member) and can be installed very easily. For interior and exterior use The object of the present invention is to propose a plate material. [Means for solving the problem]

[0007] The present invention has been proposed in view of the above, and is a device for fixing a surface plate having a surface plate and a base end, the base end of which is provided with an engagement portion and a base end of which is provided with an engagement portion. Horizontally This invention relates to an interior / exterior panel material having an extended support surface portion and a folded-down portion where the tip of the support surface portion is folded down, and is characterized in that by overlapping the support surface portions of adjacent interior / exterior panel materials on the left and right sides on a horizontal support base portion provided on a holding member, a flat exterior surface on the front side and a flat interior surface on the back side can be formed.

[0008] The present invention also relates to the For interior and exterior use In the plate material, the engaging portion is formed so as to protrude toward the face plate portion. For interior and exterior use Plate materials are also proposed.

[0009] The present invention also relates to the For interior and exterior use In the case of plate materials, the adjacent left and right For interior and exterior useA decorative material or a hanging metal fitting can be attached between the engagement parts of the plate material. For interior and exterior use Plate materials are also proposed. Effect of the Invention

[0010] The interior / exterior board material of the present invention has an extremely simple main body, and adjacent interior / exterior board materials on the left and right sides can be easily connected by a simple holding member having a horizontal support base portion. It can be used for flat interior surfaces such as ceiling surfaces (i.e., as interior materials such as ceiling materials) and flat exterior surfaces such as roof surfaces (i.e., as exterior materials such as roof materials). and can be easily formed simultaneously from the ceiling side above the holding member (support base portion).

[0011] Furthermore, when the engaging portion is formed so as to protrude toward the panel portion, this engaging portion can be used as a pressing portion against the retaining member from the side, and this rising portion can be positioned in the appropriate position without deformation of the rising portion.

[0012] In addition, the adjacent For interior and exterior use If decorative materials or hanging hardware can be attached between the engaging portions of the boards, decorative materials such as joint caps or hanging hardware for lighting fixtures, etc. can be easily attached, thereby improving the design and functionality.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The present invention For interior and exterior useThe plate material (hereinafter referred to as the main body) is characterized in that it is equipped with: on the left and right sides of the panel portion, rising portions that are raised upward and have engaging portions near their base ends, a support surface portion that extends outward from the upper end of the rising portion, and a folded portion where the tip of the support surface portion is folded down; and by connecting adjacent support surface portions of the main body on the left and right in an overlapping manner on a horizontal support base portion provided on the holding member, it can also be used as an interior material (ceiling material) or exterior material.

[0015] As described above, the main body includes a panel portion, and on the left and right sides of the panel portion, rising portions that rise upward and have engagement portions near their base ends, support surface portions that extend outward from the upper ends of the rising portions, and folded-down portions in which the tips of the support surface portions are folded down. By connecting the support surface portions of the main body adjacent to each other on the left and right sides in a superimposed manner on a horizontal support base portion provided on a holding member, the main body can be used as an interior or exterior material, and either or both of the interior and exterior surfaces can be formed. It should be noted that the "outside" refers to the direction away from the panel portion, and therefore the support surface portion is provided so as to extend further to the left from the upper end of the rising portion formed on the left side of the panel portion, and the support surface portion is provided so as to extend further to the right from the upper end of the rising portion formed on the right side of the panel portion.

[0016] The face plate portion is a portion that forms an interior or exterior surface, and may be flat or corrugated, and when forming an interior surface, a heat insulating material or various functional materials may be disposed on the upper surface. Alternatively, the face plate may be a porous face plate having many holes, and in this case, the portion (face plate portion) may be formed of, for example, punching metal, and may or may not be provided with a heat insulating material or various functional materials, but should be designed in consideration of sound absorption, light weight, etc.

[0017] The raised portion is a portion where the left and right sides of the face plate portion are raised upward, and may be substantially vertical or inclined, and an engagement portion of an appropriate shape is formed near the base end of the raised portion. This engagement portion may be a portion that engages with a holding member, or a portion to which a decorative material, a hanging metal fitting, or the like is attached. Furthermore, it is desirable that this engagement portion be formed so as to protrude toward the panel portion, and this engagement portion can be used as a pressing portion against the retaining member from the side, allowing this rising portion to be positioned in the appropriate position without deformation of the rising portion.

[0018] The support surface portion extends outward from the upper end of the raised portion and is the portion that is placed on the support base portion of the retaining member. It is also the point where adjacent main bodies are connected in a superimposed manner, so that mounting holes into which fixing devices can be driven may be formed in advance. Since this support surface portion is placed on the support base portion of the holding member in an overlapping state, by forming the support surface portion slightly larger than the width of the support base portion of the holding member, it can be attached from above in a snug fit manner. More specifically, if one of the left and right sides is located below and the other is located above, the lower support surface portion is formed slightly larger than the width of the support base portion, and the upper support surface portion is formed even slightly larger than that (the width of the lower support surface portion).

[0019] The folded-down portion is a portion where the tip of the support surface portion is folded down, and there is no particular limitation on its length (folded-down length). However, if the support surface portion is formed to be slightly larger than the width of the support base portion of the holding member as described above, this folded-down portion will be attached in an engaging manner when the support surface portion is attached in an interlocking manner.

[0020] The retaining member supporting the main body is a member having a horizontal support base as described above, and may be made of shaped steel such as C-shaped steel as in the illustrated embodiment described below, or may be a formed body of strip steel material, or may be made of plate material bent appropriately. The size (width) of the support base is not limited, and it is sufficient that a fastener such as a screw can be driven into the support surface of the adjacent main body when the support surface of the adjacent main body is placed on the support base. Also, as described above, by forming the support surface of the main body slightly larger than the width of the support base, it can be attached from above in a snug fit, and is adjusted in advance according to the width of the support surface. As for the retaining member, various configurations can be used as described above, and it may be a continuous material having a length similar to that of the main body, or it may be a number of short pieces placed at predetermined intervals.

[0021] Furthermore, the base (main body) to which this retaining member is fixed is a cross beam in the illustrated embodiment described below, but is not particularly limited thereto, and the fixing portion can be aligned along the base and fixed with an appropriate fastener.

[0022] The main body of the present invention, and the retaining members that support it, are extremely simple, and can be connected by overlapping the support surface portions formed on adjacent main bodies on the left and right sides with the support base portion of the retaining member, so construction can be easily carried out even from the roof side, making it of extremely high practical value. In particular, since construction can be carried out from the roof side, no scaffolding is required inside the room, so there is no need for a huge space for scaffolding or huge costs for constructing the scaffolding.

[0023] In addition, if decorative materials or hanging hardware can be attached between the engaging parts of the adjacent main bodies on the left and right, decorative materials such as joint caps and hanging hardware for lighting fixtures can be easily attached, improving the design and functionality.

[0024] As shown in Figure 1(a), the main body 1 of the first embodiment of the present invention is provided with, on the left and right sides of the panel portion 11, rising portions 12, 12' that are raised upward and have engagement portions 121, 121' near their base ends, support surface portions 13, 13' that extend from the upper ends of the rising portions 12, 12' toward the support base portion 21 and are placed on the support base portion 21, and folded portions 14, 14' in which the tips of the support surface portions 13, 13' are folded down, and the support surface portions 13, 13' of adjacent main bodies 1, 1 on the left and right are connected in an overlapping manner on the horizontal support base portion 21 provided on the retaining member 2, so that the main body 1 can also be used as an interior material (ceiling material) or exterior material. In addition, the raised portions, support surface portions, and folded portions formed on the left and right sides of the panel portion 11 are distinguished as 12, 13, and 14 on the sides that will become the upper surface when stacked (the left side in the drawing), and as 12', 13', and 14' on the sides that will become the lower surface (the right side in the drawing).

[0025] The retaining member 2 supporting the main body 1 is a C-shaped steel (a channel steel with a lip), and when the main body 1 is used as an exterior material, this retaining member 2 is a continuous through material in the longitudinal direction and also serves as a structural material such as a beam. The retaining member 2 in this first embodiment is a C-shaped steel as described above, and therefore its upper flange is the support base portion 21 which is a horizontal cross piece, its web is the leg portion 22 which is a vertical longitudinal piece, and its lower flange is the fixed portion 23 which is a horizontal cross piece, and the tip of the upper flange (support base portion) 21 is provided with a downward lip 211, and the tip of the lower flange (fixed portion) 23 is provided with an upward lip 231. In addition, in Figure 1 (b), the base 3 on which the retaining member 2 is erected is a cross beam or a structural body, and is made of H-shaped steel material or the like. In this embodiment, the retaining member 2 is erected (fixed) via an L-shaped steel material 3b fixed to the base 3.

[0026] As described above, when the retaining member 2 is a C-shaped steel, the following four scenarios are possible, and the combinations of these scenarios are also diverse. (1) The main body 1 is used alone as an exterior material. (2) The main body 1 is used as an exterior material, and equipment such as solar cells is placed on top of it. (3) By placing the main body 1 and then laying another exterior material on top of it, it can be used as a pure "ceiling material" (Figure 7 described below). (4) The equipment is installed inside the room via a hanging bracket below the main body 1. When the main body 1 is used as an exterior material as in (1) and (2) above, it is possible to use only the exterior material, or if the joints are visible from below, a decorative material or joint cover may be provided in the recess or C-shaped steel. In other words, by providing a decorative material or joint cover, it is possible to create a design for the ceiling surface, so it can also serve as a ceiling material. When the main body 1 is used as a ceiling material as in (3) above, the face plate can be formed using a punching material, or a heat insulating material can be laid on the face plate. The joints may or may not be covered. In the above (4), when the main body 1 is used as either an exterior material or a ceiling material, or both, as in the above (1) to (3), it is possible to further arrange accessory equipment via hanging fittings or the like.

[0027] The engagement portions 121, 121' of the main body 1 as the exterior material in this first embodiment are not shown in FIG. 1 as the portions that engage with the retaining member 2, nor as the portions to which decorative materials, hanging hardware, etc. are attached. However, if joint caps, hanging hardware, etc., described below, are arranged between the engagement portions 121, 121', the material can also be used as an interior material such as a ceiling material.

[0028] The support surface portions 13, 13' of the main body 1 as this exterior material are portions that form the exterior surface, similar to the panel portion 11, and the support surface portions 13, 13' can be fixed to the support base portion 21 of the retaining member 2 by driving fixing screws or the like (not shown) from above, however, it is desirable to carry out a waterproofing treatment to prevent the infiltration of rainwater, etc. through the fixing screws. Furthermore, the height dimension of the rising portions 12, 12' is slightly higher than the web (leg portion 22) of the holding member 2, and the width dimension of the support surface portions 13, 13' is slightly larger than the upper flange (support base portion 21), so that the main body 1 can be attached snugly to the holding member 2 from above.

[0029] The main body 1 of this first embodiment is itself extremely simple, and adjacent main bodies 1, 1 on the left and right can be easily connected using a simple retaining member (C-shaped steel) 2 equipped with a horizontal support base 21, making it easy to apply to the construction of exterior surfaces such as roof surfaces.

[0030] Figures 2(a) and 2(c) show that the main body 1 of the first embodiment can be used as both an exterior and interior material. That is, Figures 2(a) and 2(c) show the specifications of Figure 1 with joint caps 4A and hanging hardware 6 added, and the main body 1 can be used as an exterior material as is, and can also be used as a ceiling material by laying a new exterior material on top. Of these, Figure 2(a) shows an example in which a joint cap 4A shown in Figure 2(b) is attached between adjacent main bodies 1, 1 on the left and right to add a design element, and Figure 2(c) shows an example in which a hanging bracket 6 shown in Figure 2(d) is attached so as to span the engagement portions 121, 121' of adjacent main bodies 1, 1.

[0031] As shown in Figure 2(b), the joint cap 4A has a decorative lower surface 41 covering the lower flange (fixing portion 23) of the retaining member 2, an upward piece 44 along the upward lip, a vertical surface portion 42 along the leg portion 22, and an insertion portion 43 along the upper flange (support base portion 21), and an engagement piece 441 is provided at the upper end of the upward piece 44. This joint cap 4A is attached to the retaining member 2 before the main body 1 is installed, and the main body 1 is attached after the joint cap 4A is attached to the retaining member 2. At that time, the joint cap 4A is attached so that the engaging portion 121 engages with the outer side of the engaging piece 441 of the joint cap 4A. In other words, since it can be attached more stably when the main body 1 is attached, the joint cap 4A is temporarily fixed with a screw or the like before being fixed.

[0032] 2(d), the hanging hardware 6 is a piece material made by integrating multiple metal processed pieces with welding or bolts and nuts 6b, and has a horizontal top plate portion 61 with a pair of left and right bracing tips 611, 611, and a vertical piece portion 62 extending downward from the center of the top plate portion 61 toward the inside of the room, the lower end of which is bent horizontally to provide a connecting horizontal piece 63 for fixing various lighting fixtures, not shown, etc. An attachment nut 631, etc. is fixed to the connecting horizontal piece 63 so that various lighting fixtures, etc. can be easily attached. This hanging metal fitting 6 has its tension tips 611, 611 pressed against the inside of the engaging portions 121, 121' of the main body 1, 1, and because it is a piece material, the mounting position, quantity, etc. can be selected arbitrarily.

[0033] Figures 3(a) and (b) show an example in which a holding member 2B, which is made by cutting out and bending a metal plate into an appropriate shape (L-shaped when viewed from the side and approximately rectangular when viewed from the front), is pre-mounted on a base 3, and the main bodies 1,1 are attached in an engaging manner to the left and right side edges 251 of the holding member 2B. In this example, the holding member 2B has front and rear faces 25,25 of a bottom portion 24 which are raised substantially vertically and opposed to each other, and upper ends of the front and rear faces 25,25 are bent substantially horizontally outward to form support base portions 26,26. The base 3 is a structural body that serves as a cross beam, and is made of C-shaped steel, which is disposed so as to lie face down on the H-shaped steel 30 disposed further below.

[0034] The retaining member 2B is attached (molded into a shape that allows it to fit) to the left and right side edges 251, 251 of the front and rear surfaces 25, 25 so that the raised portions 12, 12' (including the engaging portions 121, 121') of the left and right main bodies 1, 1 are aligned in an engaging manner, thereby allowing the main body 1 to be attached more stably.

[0035] Figure 4 shows an example in which a retaining member 2B is used as in Figure 3 above, but a joint cap 4B is attached between adjacent retaining members 2B, 2B in the longitudinal direction, and the figure shows the procedure for simultaneously installing the main body 1 and the joint cap 4B. 2(a) (however, the installation orientation is opposite), except that it does not have the engagement piece 441, so it is given the same reference numerals in the drawings and description is omitted. Note that although this joint cap 4B does not cover the retaining member 2B from the inside of the room, it has in common the purpose of providing design between the adjacent main bodies 1, 1 on the left and right.

[0036] In Figs. 4(a) and (b), the retaining members 2B having the above-mentioned structure are fixed at predetermined intervals on the base 3 in advance, and the main body 1 and joint caps 4B are installed simultaneously thereon. That is, the main body 1 is attached to the left side of the holding member 2B located at the leftmost position, and the joint cap 4B is attached from the right side while being rotated. Furthermore, as shown in particular in Figure 4(b), the length of the joint cap 4B is shorter than the distance between adjacent bases 3, 3 in the longitudinal direction (between adjacent retaining members 2B, 2B in the longitudinal direction), so that rotation is not hindered by the retaining member 2B (i.e., the joint cap 4B is not in contact with the retaining member 2B), and the joint cap 4B can be easily rotated and attached. Thereafter, as shown in FIG. 4(c), a new main body 1 can be easily attached by fitting it from above, and thereafter, the above procedure is repeated for installation.

[0037] Figure 5(a) shows the state in which the above procedure has been repeated to place three main bodies 1 adjacent to each other on the left and right, Figure 5(b) shows a cross-sectional view of the state, and Figure 5(c) shows the combined state of the main body 1 and joint cap 4B.

[0038] In the ceiling structure constructed as shown in Figures 4 and 5, a continuous ceiling surface is formed with the panel portion 11 of the main body 1 as the ceiling material, and the joint cap 4B placed between the bases 3, 3 can be seen from the inside of the room at the joint portion, resulting in excellent design.

[0039] Figures 6(a) to 6(c) show variations of outer cover materials to be attached to the vertical bar-like portion formed at the connection portion of the adjacent main bodies 1, 1 on the left and right in the example of Figure 2(c). Note that this outer cover material may be a continuous material or a piece material depending on the purpose, and may also be a combination of multiple members. However, while the example in Fig. 2(c) uses a retaining member 2 made of C-shaped steel, Fig. 6 uses a retaining member 2B that is a formed material of the metal plate. Therefore, since the main body 1 and hanging hardware 6 in Fig. 6 are the same as those in the example in Fig. 2(c), the same reference numerals are used in the drawing, and since the retaining member 2B is the same as those in Fig. 3, the same reference numerals are used in the drawing and their explanations are omitted.

[0040] FIG. 6(a) shows an outer cover material 5A attached from above to a vertical bar-shaped portion formed at the connection portion of adjacent main bodies 1, 1 on the left and right. The outer cover material 5A is a molded body of metal or hard resin, and has a shape in which side portions 52, 52 are folded down in an umbrella shape from the left and right sides of a flat top portion 51 having a recessed portion 511 in the center, and the lower ends of the side portions 52, 52 are provided with engaging portions 521, 521 that are inwardly upwardly sprung. The engaging portions 521, 521 are attached to the outside of the left and right engaging portions 121, 121' in an engaging (fitting) manner. In addition, horizontal extending pieces 522, 522 are provided on the inside of the side portions 52, 52 toward the inside, and are arranged so as to press the left and right support surface portions 13, 13' when in an attached state. Therefore, the outer cover material 5A is attached to the vertical bar-shaped portion in a surrounding manner from above, below, left and right by the extending pieces 522, 522 of the side portions 52, 52 and the engaging portions 521, 521. The extension pieces 522, 522 prevent the outer cover material 5A from being pressed too strongly or too deeply from above. Therefore, the outer cover material 5A can be elastically fitted and attached to the adjacent main bodies 1, 1 on the left and right sides simply by pressing the vertical bar-shaped portions from above. The recess 511 provided in the center of the top 51 of the outer cover material 5A can be used as a support portion for inserting the head of a bolt (not shown) and sliding it in the longitudinal direction, and can support a snow guard, a solar cell, etc.

[0041] FIG. 6(b) shows an outer cover material 5B attached from the side to a vertical bar-shaped portion formed at the connection portion of adjacent main bodies 1, 1 on the left and right. This outer cover material 5B is an assembly of molded parts made of metal or hard resin, with symmetrical parts connected by bolts and nuts 541, and is made up of a substantially horizontal top portion 53, a substantially vertical portion 54, a substantially horizontal platform portion 55 that runs along the support surface portions 13, 13', and side portions 56, 56 that run from the side ends of the platform portion 55 to the rising portions 12, 12'. Note that horizontal extension portions 561, 561 are provided on the inside of the side portions 56, 56 toward the inside, and these extension portions 561, 561 are attached in an engaging (fitting) manner to the outsides of the left and right engagement portions 121, 121'. Therefore, the outer cover material 5B can be easily attached to the vertical bar-like portion from the side. Note that a solar cell (not shown) or the like can be supported on the top portion 53 of the outer cover material 5B.

[0042] FIG. 6(c) shows an outer cover material 5C attached from above to a vertical bar-like portion formed at the connection portion of adjacent main bodies 1, 1 on the left and right. The outer cover material 5C is a molded body of a metal plate material similar to the main body 1, and has a shape in which side portions 58, 58 are folded down in an umbrella shape from the left and right sides of a flat top portion 57, and the lower ends of the side portions 58, 58 are provided with engaging portions 581, 581 that are inwardly upwardly sprung. The engaging portions 581, 581 are attached to the outsides of the left and right engaging portions 121, 121' in an engaging (fitting) manner. Since the folded lower ends of the side portions 58, 58 are disposed close to the face plate portion 11, rainwater, etc. flowing on the face plate portion 11 is blocked by the side portions 58, 58 of the outer cover material 5C when it flows to the rising portions 12, 12' at the side ends, and therefore rainwater is prevented from entering upward along the rising portions 12, 12'.

[0043] The main body 1 in the examples shown in these Figures 6(a) to (c) can be used as having the function of either an interior material (ceiling material) or an exterior material, but as mentioned above, it functions as both an interior material (ceiling material) and an exterior material at the same time.

[0044] The vertical roofing exterior structure shown in Figure 7 comprises a W-shaped drainage member 9A arranged on the mounting base surface (support surface portions 13, 13') along the flow direction (left-right direction in Figure 7(a) and front-back direction in Figure 7(b)), a heat insulating material 9B arranged between the drainage members 9A, 9A, a support member 9C arranged so as to straddle a raised fixing portion 91 provided in the center of the drainage member 9A, a vertical roofing exterior material 7E arranged between adjacent support members 9C, 9C, and a cover material 7F covering the space between the left and right vertical roofing exterior materials 7E, 7E. The support member 9C plays the role of fixing the drainage member 9A so that it does not shift in the flow direction, and the role of elastically fitting and holding the vertical roofing exterior material 7E, and the cover material 7F is attached to the support member 9C in a fitted state simply by pressing it from above, and the vertical roofing exterior material 7E is attached in a sandwiched state between the cover material 7F and the support member 9C. Then, a substantially flat exterior surface is constructed.

[0045] In this example, the roof structure is constructed on the support surface portions 13, 13' of the main body 1 as the ceiling material, and the roof structure is not limited at all to the ceiling structure, so the exterior (roof) structure is not limited as described above.

[0046] FIG. 8(a) shows a state in which a joint cap 4C is attached between adjacent main bodies 1", 1" of the second embodiment, and the retaining member 2 supporting this main body 1" is a C-shaped steel (channel steel with a lip) as in the first embodiment.

[0047] The main body 1" in the second embodiment is similar to the main body 1 in the first embodiment with respect to the substantially horizontal face plate portion 11 and the support face portions 13, 13', but differs from the main body 1 in the first embodiment in that the rising portions 15, 15', excluding the engaging portions 151, 151', and the folded-down portions 16, 16' are substantially vertical. In other words, the rising portions 12, 12' in the first embodiment and the rising portions 15, 15' in the second embodiment are common in that they rise vertically from the face plate portion 11 and have their upper ends folded horizontally, but in the first embodiment, the rising portions 12, 12' are gently inclined from the protruding apex of the engaging portions 121, 121' to the upper ends. In contrast, in the second embodiment, the engaging portions 151, 151' are inclined at a short, steep angle from the apex of the engaging portions 151, 151', and then rise vertically again. In other words, the engaging portions 121, 121' in the first embodiment have a long upper side of the L-shaped engaging portions 121, 121', while the engaging portions 151, 151' in the second embodiment have a short upper side of the L-shaped engaging portions 121, 121'. Alternatively, the first embodiment differs in that the vertical portion of the rising portions 12, 12' exists only below the engaging portions 121, 121', whereas the second embodiment differs in that the vertical portion of the rising portions 15, 15' extends both above and below the engaging portions 151, 151'.

[0048] In addition, as shown in Figure 8 (c), the joint cap 4C has substantially vertical vertical surface portions 42", 42" raised on the left and right sides of a horizontal bottom surface portion (decorative undersurface 41"), and an attachment portion 421" bent inward in an U-shape is provided at the upper end of the vertical surface portion 42". This joint cap 4C is attached to the lower flange (fixing portion) 23 of the retaining member 2 from below, and as it is disposed between adjacent main bodies 1", 1" it is attached so as to straddle and brace between the attached portions 421", 421". Therefore, as shown enlarged in Figure 8 (b), the main body 1" has engagement portions 151, 151' which are stably attached between the adjacent attached portions 421", 421", so that the joint cap 4C also serves as an auxiliary attachment material. The main body 1" can also be used as an interior material such as a ceiling material, like the main body 1 in the first embodiment.

[0049] Therefore, this joint cap 4C needs to have a dimension at least longer than the retaining member 2 in order to hide the bottom flange 23 of the retaining member 2 which is a C-shaped steel. Furthermore, when installing this joint cap 4C, if you reach over to the underside of the decorative underside 41" from the side and lift it up, the mounting portions 421", 421" and the engaging portions 151, 151' will engage stably, and both the main body 1" and the joint cap 4C will be installed stably.
