Description

The present invention relates to a plate material for both interior and exterior, in which the members (main body and holding member) used are simple and the construction can be performed extremely easily.

A roof structure in which a tight frame is fixed to a cross beam (framework) made of a steel frame and a folded plate is laid on the tight frame is widely known.
In such a roof structure, folded plates are laid in a direction orthogonal to the longitudinal direction of the cross beam. In addition, since the cross beams are constructed at intervals of 3 to 5 m depending on the shape of the roofing material, space is required to install scaffolding on the indoor side during work such as mounting a tight frame and laying the roofing material.
Further, the ceiling structure in this case is generally performed separately from the construction of the roof structure.
Therefore, when attempting to perform ceiling construction in a gymnasium or the like after the roof construction, scaffolding or the like was required only for the ceiling construction.

For example, Patent Document 1 proposes a structure in which a wall material such as a ceiling material is erected between C-shaped steels (grooved steels with lips).
Further, Patent Document 2 proposes a structure in which a ceiling folded plate body and a folded plate roof body are laid on a beam.

Japanese Patent No. 4764375 Japanese Patent No. 5973749

However, in Patent Document 1, the wall material used is a dedicated material for the ceiling, and it is difficult to use it other than the ceiling material. Specifically, of the left and right end edges of the face plate portion, one mounting portion is mounted so as to cover the C-shaped steel, but the other mounting portion is mounted on the lip of the lower flange of the C-shaped steel. , It was a configuration that could not form a continuous exterior surface.
Further, in the above-mentioned Patent Document 2, it is not proposed that the ceiling folded plate body and the folded plate roof body having different shapes are laid in the same manner as the interior and exterior.
As described above, since the above-mentioned Patent Documents 1 and 2 cannot be used for both the roof structure and the ceiling structure, there are various problems such as the above-mentioned product management.

Therefore, an object of the present invention is to propose a plate material for both interior and exterior, in which the members (main body and holding member) used are simple and the construction can be performed extremely easily.

The present invention has been proposed in view of the above, and is a rising portion that is raised upward on the left and right sides of the face plate portion and has an engaging portion near the base end, and extends outward from the upper end of the rising portion. It is an interior / exterior combined plate material including a support surface portion and a folded portion in which the tip of the support surface portion is folded down, and is adjacent to the left and right on a horizontal support base portion provided on the holding member. The present invention relates to an interior / exterior combined plate material, which can be used as an interior material or an exterior material by connecting the support surface portions of the interior / exterior combined plate material in a polymerized manner.

The present invention also proposes an interior / exterior combined plate material characterized in that the engaging portion is formed so as to project toward the face plate portion in the interior / exterior combined plate material.

Further, the present invention is characterized in that, in the interior / exterior combined plate material, a decorative material or a hanging metal fitting can be attached between the engaging portions of the interior / exterior combined plate materials adjacent to the left and right.

It can be easily applied to the construction of an interior surface such as a surface (that is, as an interior material such as a ceiling material) and the construction of an exterior surface such as a roof surface (that is, as an exterior material such as a roof material).

Further, when the engaging portion is formed so as to project toward the face plate portion, the engaging portion can be used as a pressing portion from the side to the holding member, and the rising portion is deformed. It is possible to arrange this rising portion at an appropriate position without any problem.

In addition, if a decorative material or a hanging metal fitting can be attached between the engaging parts of the interior / exterior combined plate material adjacent to the left and right, a decorative material such as a joint cap or a hanging metal fitting such as a lighting fixture can be easily attached.

The interior / exterior combined plate material (hereinafter referred to as the main body) of the present invention has a rising portion that is raised upward on the left and right sides of the face plate portion and has an engaging portion near the base end, and extends outward from the upper end of the rising portion. The support surface portion to be supported and the support surface portion of the main body adjacent to the left and right on the horizontal support base portion provided on the holding member are provided with a folded portion in which the tip of the support surface portion is folded down. By connecting in a polymerized manner, it can also be used as an interior material (ceiling material) or an exterior material.

As described above, the main body has a face plate portion, a rising portion that is raised upward and has an engaging portion near the base end on the left and right sides thereof, and a support surface portion that extends outward from the upper end of the rising portion. It is provided with a folded portion in which the tip of the support surface portion is folded down. Then, by connecting the support surface portions of the main body adjacent to the left and right on the horizontal support base portion provided on the holding member in a polymerized manner, the interior material can also be used as an interior material or an exterior material. Either one or both of the surface and the exterior surface can be formed.
The "outside" refers to a direction away from the face plate portion, and therefore, a 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 face plate portion. A support surface portion is provided so as to extend further to the right side from the upper end of the rising portion formed on the right side of the face plate portion.

The face plate portion is a portion that forms an interior surface or an exterior surface, and may be flat or corrugated. When an interior surface is formed, a heat insulating material or various functional materials are arranged on the upper surface thereof. You may set it. Alternatively, a porous face plate having a large number of holes may be used, in which case the portion (face plate portion) can be formed by, for example, punching metal, and a heat insulating material or various functional materials may or may not be arranged. It is good, but sound absorption and light weight are taken into consideration.

The rising 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 appropriately shaped engaging portion is formed in the vicinity of the base end thereof. The engaging portion may be a portion that engages with the holding member, or may be a portion to which a decorative material, a hanging metal fitting, or the like is attached.
It is desirable that this engaging portion is formed so as to project toward the face plate portion, and this engaging portion can be used as a pressing portion from the side to the holding member, so that the rising portion is deformed. This rising portion can be arranged at an appropriate position without occurring.

The support surface portion extends outward from the upper end of the rising portion, is a portion placed on the support base portion of the holding member, and is also a portion where adjacent main bodies are connected in a polymerized manner. Therefore, a mounting hole for driving the fixture may be formed in advance.
Since this support surface portion is placed in a polymerized manner on the support base portion of the holding member, the support surface portion is formed to be slightly larger than the width length of the support base portion of the holding member, so that the support surface portion can be completely placed from above. It can be attached in a mating shape. 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 thereof. It may be formed slightly larger than (the width and length of the lower support surface portion).

The folded portion is a portion where the tip of the support surface portion is folded down, and the length thereof (folded length) is not particularly limited, but as described above, the support surface portion is held by the support base portion of the holding member. When the folded portion is formed to be slightly larger than the width of the above, the folded portion is attached in a locking shape when the support surface portion is attached in a fitted shape.

The holding member that supports the main body is a member provided with a horizontal support base as described above, and a shaped steel such as C-shaped steel may be used as in the illustrated embodiment described later, or a strip-shaped steel material. Or a plate-shaped material may be appropriately bent and used.
The size (width and length) of the support base portion is not limited as long as it can be driven with a fixing tool such as a screw while the support surface portions of adjacent main bodies are placed. Further, as described above, by forming the support surface portion of the main body slightly larger than the width length of the support base portion, the support surface portion can be completely fitted from above in a fitted shape, so that the width length of the support surface portion can be obtained in advance. It is adjusted according to.
Further, as the holding member, various configurations can be used as described above, but a continuous material having the same length as the main body may be used, or a plurality of short materials installed at predetermined intervals may be used.

Further, the base (framework) to which the holding member is fixed is a cross beam in the illustrated embodiment described later, but the present invention is not particularly limited, and the fixing portion is appropriately placed along the base with a fixing tool. It should be fixed.

The main body of the present invention itself and the holding member that supports it are extremely simple, and if the support surface portions formed on the left and right adjacent main bodies are polymerized and connected to the support base portion of the holding member. Since it is good, it can be easily constructed even from the roof side, and its practical value is extremely high.
In particular, since it can be constructed from the roof side, no scaffolding or the like is required on the indoor side, so that a huge space for scaffolding and a huge cost for scaffolding are not required.

Further, if a decorative material or a hanging metal fitting can be attached between the engaging portions of the main body adjacent to the left and right, the decorative material such as a joint cap or the hanging metal fitting such as a lighting fixture can be easily attached. , Improvement of design and improvement of functionality are achieved.

First Example

As shown in FIG. 1A, the main body 1 of the first embodiment of the present invention is raised upward on the left and right sides of the face plate portion 11 and has rising portions 121 and 121'in the vicinity of the base end. , 12', and the support surface portions 13, 13'that extend from the upper ends of the rising portions 12, 12'to the support base portion 21 side and are placed on the support base portion 21, and the support surface portion 13. , 13'with folding portions 14, 14'with the tips folded down, on the horizontal support base 21 provided on the holding member 2, the support surface portions of the main bodies 1 and 1 adjacent to each other on the left and right. By connecting 13, 13'in a polymerized manner, it can also be used as an interior material (ceiling material) or an exterior material.
Further, the rising portion, the supporting surface portion, and the folded portion formed on the left and right sides of the face plate portion 11 are set to 12, 13, 14 on the upper surface side (left side in the drawing) at the time of polymerization, and are on the lower surface side (lower surface side). In the drawing, the right side) is distinguished as 12', 13', 14'.

The holding member 2 that supports the main body 1 is a C-shaped steel (grooved steel with a lip), and when the main body 1 is used as an exterior material, the holding member 2 is a continuous through material in the length direction. Therefore, it also serves as a structural material such as a beam.
Since the holding member 2 in the first embodiment is made of C-shaped steel as described above, the leg has a support base portion 21 whose upper flange is a horizontal horizontal piece and whose web is a vertical vertical piece. The portion 22 is a fixed portion 23 in which the lower flange is a horizontal horizontal piece, and a downward lip 211 is attached to the tip of the upper flange (support base portion) 21 and a downward lip 211 is attached to the tip of the lower flange (fixed portion) 23. An upward lip 231 is provided.
The base 3 on which the holding member 2 is erected in FIG. 1 (b) is a skeleton that is a cross beam and is made of H steel or the like. In this embodiment, the base 3 is fixed to the base 3. The holding member 2 is erected (fixed) via 3b.

As described above, in the specification that the holding member 2 is a C-shaped steel, the following four assumptions are possible, and there are various combinations thereof.
(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 a solar cell is placed on it.
(3) It is used as a pure "ceiling material" by laying another exterior material on the main body 1 (FIG. 7 described later).
(4) Install the equipment on the indoor side via the hanging metal fittings below the main body 1.
When the main body 1 is used as the exterior material as in the above (1) and (2), only the exterior material may be used, or if the joints can be seen from the lower side, the concave or C-shaped steel may be used as a decorative material. Or a joint cover may be arranged. That is, by arranging the decorative material and the joint cover, the design as a ceiling surface can be obtained, so that it can also serve as a ceiling material.
When the main body 1 is used as a ceiling material as in (3) above, a face plate portion can be formed by using a punching material, or a heat insulating material can be laid on the face plate portion. The joint portion may or may not have a cover.
In the above (4), as in the above (1) to (3), in a state where the main body 1 is used as an exterior material, a ceiling material, or both, further auxiliary equipment can be arranged via a hanging metal fitting or the like. Is.

The engaging portions 121 and 121'of the main body 1 as the exterior material in the first embodiment are shown in FIG. 1 as a portion that engages with the holding member 2 and a portion to which a decorative material, a hanging metal fitting, or the like is attached. However, when a joint cap, a hanging metal fitting, or the like, which will be described later, is arranged between the engaging portions 121, 121', it can also be used as an interior material such as a ceiling material.

The support surface portions 13 and 13'of the main body 1 as the exterior material are portions that form the exterior surface like the face plate portion 11, and the support surface portions 13 and 13'are fixed to the support base portion 21 of the holding member 2. For this purpose, a fixing screw or the like (not shown) may be driven in from above, but it is desirable to perform a water stop treatment to prevent rainwater or the like from entering from the fixing screw.
Further, the height dimension of the rising portions 12, 12'is slightly higher than that of the web (leg portion 22) of the holding member 2, and the width dimension of the supporting surface portions 13, 13' is slightly higher than that of the upper flange (support base portion 21). Since it is formed large in size, the main body 1 can be completely attached to the holding member 2 from above.

The main body 1 of the first embodiment is extremely simple in itself, and the main bodies 1 and 1 adjacent to each other on the left and right are easily provided by a simple holding member (C-shaped steel) 2 provided with a horizontal support base portion 21. It can be easily applied 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 material and an interior material. That is, these FIGS. 2 (a) and 2 (c) are specifications in which the joint cap 4A and the hanging metal fitting 6 are arranged in addition to the specifications of FIG. It can also be used as a ceiling material by laying.
Of these, FIG. 2A is an example in which the joint cap 4A shown in FIG. 2B, which has a design between the main bodies 1 and 1 adjacent to the left and right, is attached, and FIG. 2C is an example. This is an example in which the hanging metal fitting 6 shown in FIG. 2D is attached so as to bridge the engaging portions 121, 121'of the adjacent main bodies 1, 1.

As shown in FIG. 2B, the joint cap 4A has a decorative lower surface 41 that covers the lower flange (fixing portion 23) of the holding member 2, an upward piece 44 along the upward lip, a vertical surface portion 42 along the leg portion 22, and an upper portion. An insertion portion 43 along the flange (support base portion 21) is provided, and an engagement piece 441 is provided at the upper end of the upward piece 44.
The joint cap 4A is attached to the holding member 2 before the arrangement of the main body 1, and the main body 1 is attached after the joint cap 4A is attached to the holding member 2. At that time, the engaging portion 121 is attached so as to engage with the outside of the engaging piece 441 of the joint cap 4A. That is, since the joint cap 4A can be attached more stably when the main body 1 is attached, the joint cap 4A is temporarily fixed before being fixed by a screw or the like.

As shown in FIG. 2D, the hanging metal fitting 6 is a piece material in which a plurality of metal processed pieces are integrated by welding or bolts and nuts 6b, and has a horizontal piece shape having a pair of left and right strut tips 611 and 611. The top plate portion 61 and the vertical piece portion 62 extend from the center of the top plate portion 61 to the indoor side in a hanging shape, and the lower end thereof is bent horizontally to fix various lighting fixtures (not shown). A horizontal piece 63 is provided. A mounting nut 631 or the like is fixed to the connecting horizontal piece 63 so that various lighting fixtures or the like can be easily mounted.
Since the hanging metal fitting 6 has a strut tip 611,611 attached to the inside of the engaging portions 121, 121'of the main bodies 1, 1 in a pressed shape and is a piece material, the attachment position, quantity, etc. can be arbitrarily selected.

In FIGS. 3A and 3B, a holding member 2B having a shape in which a metal plate material is cut out and bent into an appropriate shape (a side view is a letter shape and a front view is a substantially rectangular shape) is placed on a base 3 in advance. This is an example in which the main bodies 1 and 1 are engagedly attached to the left and right side edges 251 of the holding member 2B.
In the holding member 2B in this example, the front and rear surfaces 25 and 25 of the bottom surface portion 24 are raised substantially vertically and facing each other, and the upper ends of the front and rear surfaces 25 and 25 are bent outward substantially horizontally to support the support base. It is configured as parts 26 and 26.
The base 3 is a skeleton that is a cross beam, is made of C-shaped steel, and is arranged so as to lie down on the H-shaped steel 30 further arranged on the lower side.

In the holding member 2B, the rising portions 12, 12'(including the engaging portions 121, 121') of the left and right main bodies 1, 1 are engaged with the left and right side edges 251,251 of the front and rear surfaces 25, 25, respectively. Since it is attached in a state that conforms to the condition (molded into a shape that conforms to it), the main body 1 can be attached more stably.

FIG. 4 is an example in which the holding member 2B is used as in FIG. 3, but is an example in which the joint cap 4B is attached between the holding members 2B and 2B adjacent to each other in the length direction thereof. The procedure of constructing 1 and the joint cap 4B at the same time is shown.
The joint cap 4B is substantially the same as the joint cap 4A in FIG. 2A (however, the arrangement orientation faces each other), but is almost the same except that the engagement piece 441 is not provided. The same reference numerals are given and the description thereof will be omitted. Although the joint cap 4B does not cover the holding member 2B from the indoor side, it is common for the purpose of providing design between the main bodies 1 and 1 adjacent to the left and right.

In FIGS. 4A and 4B, the holding members 2B having the above configuration are fixed in advance on the base 3, and the main body 1 and the joint cap 4B are simultaneously constructed.
That is, the main body 1 is attached to the holding member 2B located on the leftmost side from the left side thereof, and the joint cap 4B is attached while rotating from the right side thereof.
In particular, as shown in FIG. 4B, the length of the joint cap 4B is shorter than that between the bases 3 and 3 adjacent to each other in the length direction (between the holding members 2B and 2B adjacent to each other in the length direction). The joint cap 4B can be easily rotated and attached without being hindered by the holding member 2B (that is, the joint cap 4B is not in contact with the holding member 2B).
After that, as shown in FIG. 4C, a new main body 1 can be easily attached so as to be fitted from above, and thereafter, the above procedure is repeated.

FIG. 5A shows a state in which three main bodies 1 are adjacent to each other on the left and right by repeating the above procedure, a cross-sectional view thereof is shown in FIG. 5B, and the main body 1 and a joint cap are shown in FIG. 5C. The combination state with 4B is shown.

In the ceiling structure constructed as shown in FIGS. 4 and 5, a ceiling surface is formed in which the face plate portion 11 of the main body 1 as a ceiling material is continuous, and the joint portion is formed from the indoor side to the bases 3 and 3. Since the state in which the joint cap 4B is arranged can be seen between them, the design is excellent.

6 (a) to 6 (c) show variations of the outer cover material attached to the vertical rail-shaped portion formed by the connecting portions of the main bodies 1 and 1 adjacent to each other on the left and right in the example of FIG. 2 (c). ing. The outer cover material may be a through material (continuous material) or a piece material depending on the purpose, or may be a combination of a plurality of members.
However, in the example of FIG. 2C, the holding member 2 of the C-shaped steel is used, but in FIG. 6, the holding member 2B which is a molding material of the metal plate material is used. Therefore, since the main body 1 and the hanging metal fitting 6 and the like in FIG. 6 are the same as those in FIG. 2 (c), the same reference numerals are given to the drawings, and the holding member 2B is the same as in FIG. 3 and the like. Therefore, the same reference numerals are given to the drawings and the description thereof will be omitted.

FIG. 6A shows the outer cover material 5A attached from above to the vertical rail-shaped portion formed by the connecting portions of the main bodies 1 and 1 adjacent to each other 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 surface portions 52 and 52 are folded down from the left and right of a flat top portion 51 having a concave portion 511 in the center in an umbrella shape. At the lower ends of the side surface portions 52 and 52, engaging portions 521 and 521 that are flipped up inward and upward are provided, respectively. The engaging portions 521 and 521 are attached to the outside of the left and right engaging portions 121 and 121'in an engaged (fitting) manner. Inside the side surface portions 52, 52, horizontal extending pieces 522,522 are provided toward the inside, and are arranged so as to hold down the left and right support surface portions 13, 13'in the mounted state. Therefore, the outer cover material 5A is attached to the vertical crosspiece-shaped portion in a surrounding shape from the top, bottom, left, and right by the extending pieces 522,522 of the side surface portions 52, 52 and the engaging portions 521, 521. The extending piece 522,522 prevents the outer cover material 5A from being pressed too strongly and deeply from above. Therefore, the outer cover material 5A is elastically fitted and attached to the left and right adjacent main bodies 1 and 1 simply by pressing the vertical rail portion from above.
The concave portion 511 provided in the center of the top portion 51 of the outer cover material 5A can be used as a support portion in which the head of a bolt (not shown) is recessed and slid in the length direction, and can be used as a snow stopper or a snow stopper. It can support solar cells and the like.

FIG. 6B shows the outer cover material 5B attached from the side to the vertical rail-shaped portion formed by the connecting portions of the main bodies 1 and 1 adjacent to each other on the left and right.
The outer cover material 5B is a combination of molded parts made of metal or hard resin, and symmetrical parts are connected by bolts and nuts 541. The outer cover material 5B has a substantially horizontal top portion 53 and a substantially vertical shape. 54, a substantially horizontal trapezoidal portion 55 along the support surface portions 13, 13', and side surface portions 56, 56 along the rising portions 12, 12'from the side end thereof. In addition, inside the side surface portions 56,56, horizontal extending portions 561,561 are provided toward the inside, and the extending portions 561,561 are outside the left and right engaging portions 121, 121'. It is attached in an engaged (fitting) manner.
Therefore, the outer cover material 5B can be easily attached to the vertical rail portion from the side. A solar cell or the like (not shown) can be supported on the top 53 of the outer cover material 5B.

FIG. 6 (c) shows the outer cover material 5C attached from above to the vertical crosspiece-shaped portion formed by the connecting portions of the main bodies 1 and 1 adjacent to each other 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 the side surface portions 58 and 58 are folded down from the left and right of the flat top portion 57 in an umbrella shape. At the lower ends of the 58 and 58, engaging portions 581 and 581, which are flipped up inward and upward, are provided, respectively. The engaging portions 581 and 581 are attached to the outside of the left and right engaging portions 121 and 121'in an engaged (fitting) manner. Since the bent lower ends of the side surface portions 58, 58 are arranged close to the face plate portion 11, rainwater or the like flowing on the face plate portion 11 flows to the rising portions 12, 12'at the side ends. Since it is blocked by the side surface portions 58, 58 of the outer cover material 5C, it is also possible to prevent rainwater from entering upward along the rising portions 12, 12'.

The main body 1 in the examples shown in FIGS. 6 (a) to 6 (c) can be used as having any function of the interior material (ceiling material) and the exterior material, but at the same time as described above. It functions both as an interior material (ceiling material) and as an exterior material.

The vertically-roofed exterior structure shown in FIG. 7 is arranged on the mounting base surface (support surface portions 13, 13') along the flow direction (horizontal direction in the figure (a), front-back direction in the figure (b)). Arranged so as to straddle the W-shaped drainage member 9A provided, the heat insulating material 9B disposed between the drainage members 9A and 9A, and the raised fixing portion 91 provided in the center of the drainage member 9A. The support member 9C is composed of a vertically-roofed exterior material 7E arranged between the adjacent support members 9C and 9C, and a cover material 7F covering the space between the left and right vertical-roofed exterior materials 7E and 7E.
The support member 9C plays a role of fixing the drainage member 9A so as not to shift in the flow direction and a role of elastically fitting and holding the vertical roofing exterior material 7E, and the cover material 7F presses from above. The vertical roofing exterior material 7E is attached to the support member 9C in a fitting manner only by itself, and the vertical roofing exterior material 7E is attached in a sandwiching manner 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 surface portions 13, 13'of the main body 1 as the ceiling material, and the roof structure is not limited to the ceiling structure at all. Roof) The structure is not limited.

Second Example

FIG. 8A shows a state in which the joint cap 4C is attached between the main bodies 1 ", 1" of the second embodiment adjacent to the left and right, and the holding member 2 supporting the main body 1 "is the first embodiment. Similar to the example, it is a C-shaped steel (grooved steel with a lip).

The main body 1 "in the second embodiment is the same as the main body 1 of the first embodiment with respect to the substantially horizontal face plate portion 11 and the support surface portions 13 and 13', but the rising portions 15 and 15'are engaged. It differs from the main body 1 of the first embodiment in that the portions other than the joint portions 151 and 151'and the folded portions 16 and 16'are substantially vertical, that is, the rising portions 12 and 12 in the first embodiment. 'And the rising portions 15 and 15' in the second embodiment are common in a configuration in which the rising portions 15 and 15'rise vertically from the face plate portion 11 and the upper end thereof is bent horizontally, but in the first embodiment, the engaging portion is used. Whereas the 121,121'has a gentle slope extending from the protruding apex to the upper end, in this second embodiment, the engaging portion 151, 151' has a short steep slope from the protruding apex. The difference is that they stand up vertically again from the above. In other words, the engaging portions 121 and 121'of the first embodiment have a long upper side, and the engaging portions 151 and 151 of the second embodiment. The difference is that the upper side of the dogleg is short, or in the first embodiment, the vertical portion in the rising portions 12, 12'exists only below the engaging portions 121, 121'. It can be said that the second embodiment is different in that the vertical portion of the rising portions 15 and 15'extend above and below the engaging portions 151 and 151'.

Further, as shown in FIG. 8C, in the joint cap 4C, substantially vertical vertical surface portions 42 ", 42" are raised on the left and right sides of the horizontal bottom surface portion (decorative lower surface 41 "), and the vertical surface portions 42", 42 "are raised. At the upper end of the surface portion 42 ", a mounted portion 421" bent inward in a dogleg shape is provided.
This joint cap 4C is attached to the lower flange (fixing portion) 23 of the holding member 2 from below, but since it is arranged between the adjacent main bodies 1 ", 1", it is between the attached portions 421 "and 421". It will be attached so as to straddle and stretch. Therefore, as shown in the enlarged view of FIG. 8B, the engaging portions 151 and 151'are stably attached to the adjacent portions 421 "and 421" in the main body 1 ". The joint cap 4C also contributes as a mounting auxiliary material.
The main body 1 "can also be used as an interior material such as a ceiling material as in the main body 1 in the first embodiment.

Therefore, the joint cap 4C needs to have a dimension longer than that of the holding member 2 at least for the purpose of hiding the lower flange 23 of the holding member 2 which is a C-shaped steel.
When arranging the joint cap 4C, if a hand is reached from the side to the lower surface of the decorative lower surface 41 "and lifted, the attached portions 421" and 421 "and the engaging portions 151 and 151'stable. It is engaged and the main body 1 "and the joint cap 4C can be stably attached.
