Description

The present invention relates to a board material for interior and exterior use which uses simple members (main body and retaining members) and can be installed extremely easily.

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.

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).
Furthermore, Patent Document 2 proposes a structure in which a ceiling folded plate body and a folded plate roof body are laid on a beam.

Patent No. 4764375 Patent No. 5973749

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 ceiling materials. 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 involves laying a ceiling folded plate body and a folded plate roof body that are of different shapes to begin with.
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.

SUMMARY OF THE PRESENT EMBODIMENTS The present invention aims to provide an interior/exterior panel material which uses simple members (main body and retaining members) and which can be installed extremely easily.

The present invention has been proposed in view of the above, and relates to an interior/exterior panel material which comprises, on the left and right sides of a panel portion, rising portions which are raised upward and have engaging portions near their base ends, support surface portions which extend horizontally outward from the upper ends of the rising portions, and folded-down portions where the tips of the support surface portions are folded down, and which 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, it is possible to form an exterior surface which has a flat front surface and an interior surface which has a flat back surface.

The present invention also proposes the interior/exterior panel material, characterized in that the engagement portion is formed so as to protrude toward the face plate portion.

The present invention also proposes the interior/exterior panel material as described above, characterized in that a decorative material or a hanging metal fitting can be attached between the engaging portions of the interior/exterior panel materials adjacent to each other on the left and right.

The interior/exterior panel material of the present invention is extremely simple in terms of its main body, and adjacent interior/exterior panel materials on the left and right can be easily connected using a simple holding member with a horizontal support base. It is therefore easy to simultaneously form a flat interior surface such as a ceiling surface (i.e., as an interior material such as a ceiling material) and a flat exterior surface such as a roof surface (i.e., as an exterior material such as a roof material) from the ceiling side above the holding member (support base).

In addition, if the engaging portion is formed so as to protrude toward the face plate portion, this engaging portion can be used as a portion to be pressed against the holding member from the side, and this rising portion can be positioned in the appropriate position without causing deformation of the rising portion.

Furthermore, if decorative materials or hanging hardware can be attached between the engaging portions of adjacent interior and exterior panel materials on the left and right, decorative materials such as joint caps and hanging hardware for lighting fixtures, etc. can be easily attached, thereby improving the design and functionality.

The interior/exterior panel material of the present invention (hereinafter referred to as the main body) is characterized in that it comprises, 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-down 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 a retaining member, it can also be used as an interior material (ceiling material) or exterior material.

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.

The panel portion is a portion that forms the interior or exterior surface, and may be flat or corrugated. When forming an interior surface, a heat insulating material or various functional materials may be disposed on the upper surface. Alternatively, it may be a porous panel with many holes. In that case, the part (panel portion) may be formed from, for example, punched metal, and may or may not be provided with a heat insulating material or various functional materials, but will be designed with consideration given to sound absorption, light weight, etc.

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.

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 state. 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).

The folded portion is the portion where the tip of the support surface portion is folded down, and there is no particular limit to its length (folded down length), but if the support surface portion is formed to be slightly larger than the width of the support base portion of the retaining member as described above, this folded portion will be attached in an engaging manner when the support surface portion is attached in an interlocking manner.

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 in while the support surface of the adjacent main body is placed on it. 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.

The base (framework) to which the retaining member is fixed is a cross beam in the illustrated embodiment described below, but is not limited thereto, and the fixing portion can be fitted along the base and fixed with an appropriate fastener.

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.

In addition, if decorative materials or hanging hardware can be attached between the engaging parts of the body adjacent to each other 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.

First embodiment

As shown in Figure 1 (a), the main body 1 of the first embodiment of the present invention is provided with rising portions 12, 12' on the left and right sides of the panel portion 11 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 a superimposed 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 overlapped (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).

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 fixing 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 (fixing 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 structural body which is a cross beam and is made of H-shaped steel material or the like, and in this embodiment, the retaining member 2 is erected (fixed) via an L-shaped steel 3b fixed to the base 3.

As described above, when the retaining member 2 is a C-shaped steel, the following four assumptions are possible, and the combinations of these 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 another exterior material on top of the main body 1, it can be used as a pure "ceiling material" (see FIG. 7 described later).
(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, only the exterior material may be used, or if the joints are visible from below, decorative material or joint covers may be provided in the recesses or C-shaped steel. In other words, by providing decorative material or joint covers, it is possible to create a design for the ceiling surface, so that it can also serve as a ceiling material.
When the main body 1 is used as a ceiling material as in the above (3), 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.

The engaging parts 121, 121' of the main body 1 as the exterior material in this first embodiment are not shown in FIG. 1 as the parts that engage with the retaining member 2, nor as the parts to which decorative materials or hanging hardware are attached. However, if joint caps or hanging hardware, which will be described later, are placed between the engaging parts 121, 121', the main body 1 can also be used as an interior material such as a ceiling material.

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 in order to fix the support surface portions 13, 13' to the support base portion 21 of the holding member 2, fixing screws (not shown) or the like may be driven in from above, but it is desirable to carry out a waterproofing treatment to prevent the infiltration of rainwater, etc. through the fixing screws.
In addition, 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.

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 with a simple holding 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.

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, these figures 2(a) and 2(c) show the specifications of the main body 1 of the first embodiment, with joint caps 4A and hanging hardware 6 added to the specifications of Figure 1, 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) is 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) is an example in which a hanging bracket 6 shown in Figure 2(d) is attached so as to span the engaging portions 121, 121' of adjacent main bodies 1, 1.

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 outside of the engaging piece 441 of the joint cap 4A. In other words, since the joint cap 4A 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.

The hanging hardware 6 is a piece material made by integrating multiple metal processed pieces with welding or bolts and nuts 6b as shown in Fig. 2(d), and comprises a horizontal top plate portion 61 having 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. A mounting nut 631, etc. is fixed to the connecting horizontal piece 63 so that various lighting fixtures, etc. can be easily attached.
This hanging fitting 6 has its bracing tips 611, 611 pressed against the inside of the engaging portions 121, 121' of the main bodies 1, 1, and because it is a piece material, the mounting position, quantity, etc. can be selected arbitrarily.

3(a) and (b) show an example in which a retaining member 2B, which is formed 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 retaining 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 face down on the H-shaped steel 30 disposed further below.

The holding member 2B is attached to the left and right side edges 251, 251 of the front and rear faces 25, 25 in such a way that the rising portions 12, 12' (including the engaging portions 121, 121') of the left and right main bodies 1, 1 are aligned in an engaging manner (the holding member 2B is molded into a shape that allows the main body 1 to be attached more stably).

Figure 4 shows an example in which a retaining member 2B is used as in Figure 3, 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.
This joint cap 4B is almost the same as the joint cap 4A in Fig. 2(a) (however, the installation direction is opposite), and is almost the same except that it does not have the engagement piece 441, so the same reference numerals are given to it in the drawings and the description is omitted. Note that this joint cap 4B does not cover the retaining member 2B from the inside of the room, but it has the same purpose as the joint cap 4A in providing a design between the adjacent main bodies 1, 1 on the left and right.

In Figures 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.
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 installed.
Thereafter, as shown in FIG. 4(c), a new main body 1 can be easily attached by fitting it from above, and the above procedure is thereafter repeated for installation.

Figure 5(a) shows the state where three main bodies 1 are placed side by side by repeating the above procedure, Figure 5(b) shows a cross-sectional view of the state, and Figure 5(c) shows the combination of the main body 1 and the joint cap 4B.

In this way, in a 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, resulting in an excellent design.

6(a) to 6(c) show variations of the outer cover material 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 Fig. 2(c) above. Note that this outer cover material may be a continuous material or a piece material depending on the purpose, or may 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 which 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.

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 central recessed portion 511, and the lower ends of the side portions 52, 52 are provided with engaging portions 521, 521 that are raised upward inward. 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 to press the left and right support surface portions 13, 13' when attached. 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.
In addition, the recessed portion 511 provided in the center of the top 51 of this outer cover material 5A can be used as a support portion for recessing the head of a bolt (not shown) and sliding it in the longitudinal direction, and can support snow guards, solar cells, etc.

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. A solar cell (not shown) or the like can be supported on the top portion 53 of the outer cover material 5B.

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 from the left and right sides of a flat top portion 57 in an umbrella shape, and the lower ends of the side portions 58, 58 are provided with engaging portions 581, 581 that are raised upward inward. 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'.

The main body 1 in the examples shown in these Figures 6(a) to (c) can be used as 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.

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.

In this example, the roof structure is constructed on the support surfaces 13, 13' of the main body 1 as the ceiling material, and there are no restrictions on the roof structure, so as mentioned above, the exterior (roof) structure is not limited.

Second embodiment

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

The main body 1" in this second embodiment is similar to the main body 1 in the first embodiment with respect to the substantially horizontal face plate portion 11 and 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 this 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, they are gently inclined from the protruding apex of the engaging portions 121, 121' to their upper ends. In contrast, in the second embodiment, the engaging portions 151, 151' have a short, steeply inclined apex 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-shape, while the engaging portions 151, 151' in the second embodiment have a short upper side of the L-shape. Alternatively, in the first embodiment, the vertical portion of the rising portions 12, 12' exists only below the engaging portions 121, 121', whereas in the second embodiment, the vertical portion of the rising portions 15, 15' extends both above and below the engaging portions 151, 151'.

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 L-shape is provided at the upper end of the vertical surface portion 42".
This joint cap 4C is attached from below to the lower flange (fixing portion) 23 of the retaining member 2, but since 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" is stably attached between the adjacent attached portions 421", 421", with the engagement portions 151, 151', 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.

Therefore, in order to hide the lower flange 23 of the retaining member 2, which is a C-shaped steel, the joint cap 4C needs to have a dimension at least longer than the retaining member 2.
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 stably installed.
