Description

  The present invention relates to a roof structure that provides a structure with improved fire safety against a flying fire in the event of a fire or the like in a folded-plate roof provided with a daylighting unit.

  When installing a daylighting part on a folded-plate roof used for the roof of a factory or a warehouse, it is possible to replace a part of the metal folded-plate roof material made of a steel plate with a resin folded-plate roof material made of a transparent synthetic resin plate. . However, the resin folded plate roofing material is a fireproof safety because the resin melts and perforates when a spark comes in the event of a fire, etc., and the spark enters the interior from this hole or the molten resin falls indoors. There is a problem with sex.

  Therefore, conventionally, an invention has been made in which a part of the metal folded plate roofing material is replaced with a glass plate (for example, see Patent Document 1). However, when the glass plate is fitted between the folded metal roof materials, it is necessary to attach the glass plate with a watertight structure, so that there is a problem that the structure becomes complicated and the construction becomes troublesome. Moreover, since glass plates cannot withstand the stress caused by deformation and are easily damaged, it is necessary to provide a strong and high-accuracy frame material that receives stress and does not transmit it to the glass, which also makes the structure complicated and expensive. There was a problem of becoming. Furthermore, since the glass plate has high incombustibility but low impact resistance, it easily breaks when an object comes to the roof due to strong winds or the like, and once broken, the repair work becomes troublesome.

Moreover, conventionally, a part of the metal folded plate roofing material is changed to a reinforced translucent folded plate roofing material in which a translucent and incombustible translucent incombustible plate is laminated and integrated on the back surface of the translucent synthetic resin plate. A replacement invention has also been made (see, for example, Patent Document 2). This reinforced translucent folded plate roofing material has a certain level of impact resistance compared to a translucent incombustible plate such as a glass plate. Fireproof safety is high because the non-combustible plate can shield fire and molten resin. However, this reinforced translucent folded plate roofing material has a complex structure in which a translucent incombustible plate is laminated and integrated on the back surface of a synthetic resin plate, so compared to a folded plate roofing material consisting of only a steel plate or a synthetic resin plate. There has been a problem that the manufacturing cost becomes extremely high.

  Hereinafter, the best embodiment of the present invention will be described with reference to FIGS.

  In the present embodiment, as shown in FIG. 1, one metal folded plate roofing material 3 is disposed between the tops of adjacent mountain parts 2 a of the tight frame 2 fixed on the purlin material 1, and these A roof structure in which one of the metal folded plate roofing materials 3 is replaced with a resin folded plate roofing material 4 to provide a daylighting portion will be described.

[Mounting structure of metal folded plate roofing material and resin folded plate roofing material]
The main building 1 is a structural material arranged on the roof, and as shown in FIG. 2, is composed of a long I-shaped rope or a H-shaped rope on the left and right, and two or more in the front-rear direction (only two in FIG. 2) Are arranged in parallel. Further, although not shown in the figure, these purlins 1 are arranged such that the height of the front one is lower so that the front is under water. The purlin material 1 is not limited to the I-shaped rope and the H-shaped rope as in the present embodiment, and any type of rope or other structural material may be used.

  The tight frame 2 is formed by alternately forming a crest 2a that is a convex portion in the vertical direction and a trough portion that is a concave portion in the left-right direction on a steel plate that is elongated to the left and right, and welding the trough to the upper surface of the base material 1. It is fixed by the method of. In addition, a flat portion slightly lower than the highest top is formed at the top of the peak portion 2a of the tight frame 2, and a screw hole is formed. Further, the tight frame 2 of the present embodiment is not a simple elongated flat plate as shown in the figure, but actually, a rib having a semicircular cross section along the longitudinal direction is formed for reinforcement.

  In addition, the shape of the peak part 2a and the trough part of this tight frame 2 is arbitrary according to the bending shape of the metal folded-plate roof material 3 or the resin folded-plate roof material 4, and the structure of the top part of the peak part 2a, ie, flat The presence or absence of a part and a screw hole is also arbitrary. 1 to 9, the tight frame 2 has only two peak portions 2a. However, a large number of peak portions 2a and valley portions may be formed. 2a may be only one place. However, when using the tight frame 2 with few ridges 2a, a plurality of tight frames 2 are arranged in a row in the left-right direction for each purlin member 1 and fixed. Further, the tight frame 2 is not limited to a steel plate as long as a required strength is obtained, and may be made of other metal materials such as other steel materials and stainless steel, and the presence or absence of ribs is also arbitrary. .

  The metal folded plate roofing material 3 is made of a steel plate, and as shown in FIG. 1, the shape of the cross section along the vertical and horizontal directions is from the top of the peak 2 a of the tight frame 2 to the valley of the adjacent peak 2 a. It is formed in substantially the same uneven shape as the shape reaching the top. However, in FIG. 1, the right metal folded plate roofing material 3 shows only a part from the top of the peak portion 2 a of the tight frame 2 to the right trough portion thereof, and the left metal folded plate roofing material 3 is tight. Only a part from the valley of the frame 2 to the top of the peak 2a on the right side is shown. In addition, this metal folded-plate roof material 3 may consist of other metal plates, such as not only a steel plate like this embodiment but aluminum, a stainless steel rope.

  The resin folded plate roofing material 4 is made of a synthetic resin plate having translucency, and the shape of the cross section along the vertical and horizontal directions is from the top of the peak 2a of the tight frame 2 through the valley to the adjacent peak 2a. It is formed in substantially the same uneven shape as the shape reaching the top. Here, translucency refers to the property of transmitting visible light and is not limited to being transparent. For example, it may transmit light while scattering it, or may absorb part of light. Good. In addition, as the synthetic resin plate, a plate material of polycarbonate resin or acrylic resin with high light transmittance is optimal, and other thermoplastic resins such as polyester resin and vinyl chloride resin are also suitably used. Is not limited. Moreover, the synthetic resin plate may be a plate material made of a synthetic resin with various additives added thereto, or may be a plate material having a multilayer structure by providing a weather resistant layer or the like. Further, the synthetic resin plate may be a plate material made of a reinforced resin containing glass fiber or the like in a synthetic resin.

  In addition, these metal folded-plate roof materials 3 and resin folded-plate roof materials 4 are not restricted to what was uneven | corrugated shape only for 1 cycle in the left-right direction like this embodiment, Furthermore, many uneven | corrugated shapes are It may be formed. The length of the metal folded plate roofing material 3 and the resin folded plate roofing material 4 in the front-rear direction only needs to be long enough to be bridged on at least two main building materials 1, and three or more. There may be a length that spans over the main purlin 1 of the house.

  The metal folded plate roofing material 3 is placed side by side on a plurality of purlins 1 arranged in front and rear. At this time, each metal folded plate roofing material 3 is placed between the top of the peak 2a of the tight frame 2 fixed on the purlin 1 and the top of the adjacent peak 2a. The other metal folded plate roofing materials 3 are connected by caulking the ends to each other via a long metal suspension 5 attached to the top of each peak portion 2a. Moreover, these metal folded-plate roof materials 3 replace only the said resin folded-plate roof material 4, and arrange | position this part as the lighting part of a folded-plate roof. Therefore, the resin folded plate roofing material 4 is also connected by caulking the left and right end portions with the end portions of the adjacent metal folded plate roofing material 3 via the suspension 5. The metal folded plate roofing material 3 and the resin folded plate roofing material 4 have a watertight structure by caulking the end portions with the suspension 5 in this manner.

  However, the left hanging element 5 in FIG. 1 is not the ends of the metal folded plate roofing material 3 but the ends of the resin folded plate roofing material 4 having a different material and thickness from the ends of the metal folded plate roofing material 3. Since it is caulked so as to cover the part, it is made of a metal having a small thickness, different from the normal hanging element 5, and a short thing attached to each peak part 2 a of the tight frame 2 is used. In addition, the caulked portion between the ends of the metal folded plate roofing material 3 and the resin folded plate roofing material 4 by the left hanging element 5 in FIG. 1 is an aluminum plate that is long in the front and rear directions in order to ensure a watertight structure. It is covered with a cap member made of

  In addition, the watertight structure of the metal folded plate roof material 3 or the resin folded plate roof material 4 is not necessarily limited to caulking via the suspension 5, but may be a watertight structure by other connecting means. Further, the resin folded plate roof material 4 is not replaced with the metal folded plate roof material 3 as in the present embodiment, but is replaced with a plurality of continuous metal folded plate roof materials 3 or continuously. You may make it replace with the several metal folded-plate roof material 3 which is not.

[Support structure of translucent incombustible plate]
The support structure for arrange | positioning the translucent incombustible board 6 below the resin folded-plate roof material 4 in the said roof structure is demonstrated. 2 to 7 and FIG. 9, only the support structure between the two purlins 1 will be described. However, when the resin folded plate roof material 4 is bridged over three or more purlins 1. A similar support structure is formed between the purlins 1.

  2 to 9, only one tight frame 2 having two peaks 2a is shown for each main building 1, but the other tight frames 2 that are continuously fixed to the left and right are not shown. ing. The tight frame 2 having two peak portions 2a shown in FIGS. 2 to 9 has a resin folded plate roof material 4 arranged between the tops of both peak portions 2a shown in FIG. Then, as shown in FIG. 2, two light-transmitting non-combustible plates 6 are arranged side by side in the left-right direction position of these tight frames 2 between the two purlins 1. Also, a left receiving member 7 and a right receiving member 8 are disposed on the left and right sides of the two light-transmitting non-combustible plates 6. And the front and rear receiving materials 9 are respectively arranged below the fixing positions of the tight frames 2 on the two purlins 1. Further, a front / rear joint receiving material 10 is disposed under the two light-transmitting non-combustible plates 6. Since FIG. 2 is an assembly drawing, all members other than the purlin material 1 are shown displaced upward.

  The translucent incombustible plate 6 is a plate-shaped translucent incombustible material made of a translucent incombustible material, and in the present embodiment, is made of a square netted glass. In addition, the translucency here is also the same as the case of the resin folded-plate roof material 4, and transparent is also included.

  The left receiving member 7 is a substantially rectangular metal plate whose front and rear length is substantially the same as that between the two purlins 1 and whose top and bottom are slightly longer than the height of the peak portion 2a of the tight frame 2, and the upper end is on the right side. The bent portions are bent at right angles to the direction, and the bent portions are further protruded in the front-rear direction to form locking portions 7a. Moreover, in order to avoid interference with the purlin 1, the lower end portion of the left-side receiving member 7 is cut out at the front and rear corners, and the lower portion of the cut-out portion is bent at right angles to the right and supported. Part 7b is formed. The front and rear locking portions 7a are locked to the peak portions 2a of the tight frame 2 fixed on the purlin member 1, and holes for locking are formed. The support part 7b supports the left end part of the two translucent incombustible plates 6, respectively.

  The right receiving member 8 is also a substantially rectangular metal plate whose front and rear length is substantially the same as that between the two purlins 1 and whose top and bottom are slightly longer than the height of the peak portion 2 a of the tight frame 2. Then, the upper end portion is bent at a right angle in the left direction, and the bent portion is further protruded in the front-rear direction to form a locking portion 8a. Further, the lower end portion of the right receiving member 8 is notched at the front and rear corners in order to avoid interference with the purlin material 1, and is supported by bending the lower portion of the notched portion at a right angle to the left. Part 8b is formed. The front and rear locking portions 8a are locked to the peak portions 2a of the tight frame 2 fixed on the purlin member 1, and holes for locking are formed. The support part 8b supports the right end part of the two translucent incombustible plates 6, respectively.

  The left receiving member 7 and the right receiving member 8 are preferably made of aluminum or an aluminum alloy plate in order to reduce the weight. Further, an iron plate may be used, and a stainless steel plate is used when emphasizing corrosion resistance, and a steel plate may be used when emphasizing fire resistance. Further, the left receiving member 7 and the right receiving member 8 do not need to be substantially rectangular as in the present embodiment, and are formed with locking portions 7a and 8a that protrude from the upper part in the front-rear direction, and the lower part. Need only be formed with support portions 7b, 8b protruding in the left and right directions facing each other. The locking portions 7a and 8a may be of an appropriate structure corresponding to the configuration of the flat portion or the like of the peak portion 2a in order to be locked to the peak portion 2a of the tight frame 2, and the support portions 7b and 8b are also provided. In order to support the translucent incombustible plate 6, for example, it may have an appropriate structure such as protruding only at a few places in place. In addition, the left receiving member 7 and the right receiving member 8 do not have to be plate-like, for example, an elongated metal plate or a metal rod is arranged only at the edge of a square or arranged in a truss structure. Also good.

  The front / rear receiving material 9 is formed by bending a rectangular metal plate having a lateral length substantially equal to the distance between the left receiving material 7 and the right receiving material 8 into a U-shaped cross section with the opening facing downward. The lower portions on the front side are further bent forward at a right angle and protruded, and the lower portions on the rear side are further bent at a right angle and protruded rearward to form the support portions 9a. The front and rear support portions 9a support the rear end portion of the rear translucent incombustible plate 6 and the front end portion of the front translucent noncombustible plate 6, respectively. The front and rear receiving members 9 are placed on the left and right positions between the left receiving member 7 and the right receiving member 8 in the main building material 1 so as to straddle the main building material 1 and are fixed by welding or the like. The

  As long as the said front-and-rear receiving material 9 is arrange | positioned so that the top of the main building material 1 may be straddled back and forth, it does not necessarily need to be a thing which bent the square metal plate into the U-shaped cross section, for example, elongate metal The metal frame etc. which were comprised so that it could arrange | position so that it might straddle on the front and back materials 1 using the board and the metal rod may be sufficient. Further, the support portion 9a may also have an appropriate structure, for example, if it protrudes forward and backward from the lower portion straddling the front and rear of the front and rear receiving material 9, for example, only a few locations protrude at appropriate positions. Further, since the front and rear receiving material 9 supports the translucent incombustible plate 6 in the front and rear directions, the support of the translucent incombustible plate 6 is left to the left and right left receiving materials 7 and the right receiving material 8 only. The use of the material 9 can also be omitted.

  The front-rear joint receiver 10 is made of a metal material that is long in the left-right direction and whose length in the left-right direction is substantially equal to the distance between the left-side receiver 7 and the right-side receiver 8. In addition, since the lateral cross section that is long to the left and right is an inverted T shape, the lower horizontal portion of the inverted T shape is a support portion 10a that protrudes in the front-rear direction. This front / rear joint receiving material 10 is disposed between two translucent incombustible plates 6 and supports the end portions on the sides adjacent to each other before and after these translucent incombustible plates 6 by front and rear support portions 10a. is there.

  The front / rear joint receiver 10 does not necessarily have an inverted T-shaped cross section, and may be a horizontal metal plate that is simply elongated to the left and right, for example. In this case, the front side and the rear side of the metal plate are the support portions 10a, respectively. Moreover, since the front-rear joint receiving material 10 supports the end portions on the adjacent side of the two light-transmitting non-combustible plates 6, the use of the front-rear joint receiving material 10 can be omitted. When the non-combustible plate 6 is not divided into two pieces before and after and is a single piece of netted glass, there is no need to use it.

[Procedure for translucent incombustible plate]
An example of the construction procedure of the translucent incombustible plate 6 and the receiving materials 7 to 10 will be described with reference to FIGS.

  As shown in FIG. 3, first, the front and rear receiving materials 9 are first placed and fixed on each main building material 1. Then, as shown in FIG. 4, the tight frame 2 is placed on the purlin member 1 to which the front and rear receiving materials 9 are fixed, and the valleys of the tight frame 2 are fixed to the front and rear receiving materials 9 and the main purlin material 1. To do. The tight frame 2 and the front and rear receiving materials 9 are usually fixed by welding, but this fixing means is arbitrary. For example, the tight frame 2 and the front and rear receiving materials 9 are collectively fixed to the main building material 1 by screwing. You can also

  As shown in FIG. 5, the left receiving member 7 and the right receiving member 8 are locked between the front and rear peak portions 2a of the tight frame 2 fixed on the two purlins 1 as described above. Is done. That is, the left receiving member 7 places the front and rear engaging portions 7a on the flat portions formed on the left ridges 2a of the front and rear tight frames 2, and the right receiving member 8 includes the front and rear engaging portions. 8a is placed on the flat part formed on the right peak part 2a of the front and rear tight frames 2, respectively, and is arranged so as to be bridged between the front and rear tight frames 2. At this time, the front and rear ends of the support portions 7b and 8b of the left receiving member 7 and the right receiving member 8 overlap with the left and right end portions of the supporting portion 9a of the front and rear receiving member 9, so It is fixed by tightening. The fixing means for the support portions 7b and 8b and the support portion 9a is not limited to rivets, and is not necessarily fixed.

  As shown in FIG. 6, the front and rear joint receiver 10 is locked at the front and rear central portions between the left receiver 7 and the right receiver 8. That is, the front / rear joint receiver 10 has the left end placed on the support 7b of the left receiver 7 and rivets the support 7b and the support 10a of the front / rear joint receiver 10 with rivets. The right end portion is placed on the support portion 8b of the right receiving member 8, and the support portion 8b and the supporting portion 10a of the front and rear joint receiving member 10 are fixed by rivets. The fixing means for the front / rear joint receiver 10 is not limited to a rivet, and any means may be used, and the front / rear joint receiver 10 may simply be placed without fixing.

  As described above, between the left receiving member 7 and the right receiving member 8, the support portions 7 b and 8 b of the left receiving member 7 and the right receiving member 8, the supporting portion 9 a of the front and rear receiving member 9, and the front and rear joint receiving member 10. The front and rear two regions surrounded by the four sides are formed by the support portion 10a. And as shown in FIG. 7, the translucent incombustible board 6 is each mounted in the area | region of two places between these left side receiving materials 7 and the right side receiving materials 8. As shown in FIG. Moreover, these two translucent incombustible plates 6 are stopped by applying a caulking agent in the vicinity of the boundaries with the support portions 7b, 8b, 9a and 10a at the four corners, respectively. Instead of applying the caulking agent, a packing agent may be applied in advance on the support portions 7b, 8b, 9a, and 10a, and the translucent incombustible plate 6 may be placed thereon to be stopped. . However, the translucent incombustible plate 6 is only required to be supported by these support portions 7b, 8b, 9a, 10a, and a watertight structure is not particularly required. Is unnecessary.

  Although the construction procedure between the two purlins 1 has been described above, when the resin folded plate roofing material 4 is bridged over a large number of purlins 1, as shown in FIG. Between each of the materials 1, the receiving materials 7 to 10 and the translucent incombustible plate 6 are attached in the same manner as described above. At this time, on the flat portion of the peak portion 2a of the tight frame 2, the front and rear left receiving members 7 and the engaging portions 7a and 8a of the right receiving member 8 are placed in an overlapped manner. Then, by screwing the bolt 11 into the screw hole formed in the flat portion of the peak portion 2a through the holes of the two locking portions 7a and 8a, the left receiving member 7 and the right receiving member 8 are tightly attached to the front and rear. It is locked and fixed to the peak portion 2 a of the frame 2. In the case of the tight frame 2 fixed on the front and rear purlins 1 or when the resin folded plate roof material 4 is bridged only on the two purlins 1, Only one locking portion 7a or locking portion 8a is placed on the flat portion of the portion 2a. In these cases, the bolts 11 are similarly screwed and fixed. The locking means of the locking portions 7a, 8a of the left receiving material 7 and the right receiving material 8 is arbitrary, and may be locked by locking means other than the bolt 11, or the peak portion 2a of the tight frame 2. It can also be locked to other than the flat part.

  When the support of the translucent incombustible plate 6 by the receiving materials 7 to 10 is completed as described above, one resin folded plate roof material 4 on the two or more purlin materials 1 and a plurality of metal folded plates on the left and right sides thereof. The plate roof material 3 is placed, and as shown in FIG. 1, the ends of the metal folded plate roof material 3 and the resin folded plate roof material 4 are caulked and connected via a suspension 5, thereby folding the plate. The construction of the roof is completed. However, since the hanger 5 is fixed to the flat portion of the peak portion 2a of the tight frame 2 by the bolt 11, in fact, the left receiving member 7 and the right receiving member 8 are not attached to the flat portion of the peak portion 2a. Not only the locking portions 7a and 8a but also the lower end portion of the suspension 5 is placed and fixed together by the bolt 11.

  With the above configuration, the translucent incombustible plate 6 can be supported below the resin folded plate roof material 4 using the receiving materials 7 to 10 such as the left receiving material 7 and the right receiving material 8. Even if there is a hole in the resin folded plate roof material 4, it is possible to reliably prevent flying fire that has passed through the hole or molten resin from entering the room by the light-transmitting non-combustible plate 6 made of a non-combustible material. Can be secured. For example, when a glass-filled glass is used as the translucent incombustible plate 6 and a steel plate is used as the receiving materials 7 to 10, it corresponds to the fireproof structure of Article 2, Item 7 of the Building Standards Act, and the translucent incombustible plate 6 The other materials of materials 7 to 10 correspond to at least the non-combustible material of the same article No. 9.

  Moreover, since the resin folded plate roofing material 4 is disposed below the resin folded plate roofing material 4 attached together with the metal folded plate roofing material 3, it is not necessary to consider a watertight structure, and the receiving members 7 to 10 are simple. Construction is easy due to the structure.

  Further, the translucent incombustible plate 6 is reliably supported not only by the support portions 7 b and 8 b of the left receiving material 7 and the right receiving material 8 but also by the support portions 9 a of the front and rear receiving materials 9. Furthermore, since the translucent incombustible plate 6 is divided into two parts in the front and rear, and the divided part is supported by the support part 10a of the front and rear joint receiving material 10, the size of the meshed glass is reduced and stably supported. Will be able to. Further, since the light-transmitting non-flammable plate 6 is made of meshed glass, the light transmittance is higher than that of other light-transmitting non-flammable materials that have translucency, but light that has entered from the resin folded-plate roofing material 4. Can be taken indoors efficiently. Moreover, even if the glass with a mesh breaks for some reason, the glass fragments do not scatter or fall off, so that the safety of the roof structure can be improved.

[Other Embodiments]
In addition, in the said embodiment, although the case where the translucent incombustible board 6 was divided into 2 front and back was shown, whether to divide into front and back can be arbitrarily determined according to the size of the translucent incombustible board 6, etc. And when the translucent incombustible board 6 is not divided | segmented into front and back, the front-and-rear joint receiving material 10 becomes unnecessary. And the division | segmentation number which divides the translucent incombustible board 6 back and front can also be decided arbitrarily similarly, and when it divides | segments into 3 or more divisions, the front-and-rear joint receiving material 10 is provided for every division part of the translucent incombustible board 6. What is necessary is just to arrange.

  Moreover, in the said embodiment, although the case where the translucent incombustible board 6 was not divided | segmented into right and left was shown, whether to divide into right and left can be arbitrarily determined according to the size of the translucent incombustible board 6, etc. And when the translucent incombustible plate 6 is divided | segmented into right and left, it is the structure similar to the front-and-rear joint receiving material 10, Comprising: A right and left long left-right joint receiving material is divided for every right and left division part of the translucent incombustible plate 6 What is necessary is just to arrange. However, this left and right joint receiving material has the front end placed on the support portion 9a behind the front front / rear receiving material 9 and the rear end attached to the support portion 9a before the rear front / rear receiving material 9. Since it is mounted and the support portion of the left and right joint receiving material and the support portion 9a of the front and rear receiving material 9 are locked by rivets or the like, the translucent incombustible plate 6 is divided into left and right receiving portions. Only when the material 9 is used.

  Moreover, as shown in FIG. 9, the translucent incombustible plate 6 can also be divided | segmented into both the front-back and left-right direction (in FIG. 9, 4 divisions). In this case, the front / rear joint receiver 10 is the same as that of the above-described embodiment, and the left / right joint receiver 12 has a distance between the two purlins 1 divided by a fraction of the front and rear (in FIG. 9, 1 / A number slightly shorter than 2) is used for the number of front and rear divisions (two in FIG. 9). These left and right joint receiving members 12 are arranged at the front end, and the front end is placed on the support portion 9a of the front and rear receiving member 9, and the rear end is the supporting portion of the front and rear joint receiving member 10. What is placed on the rear end is placed on the support portion 9a of the front and rear receiving material 9 and the front end is placed on the support portion 10a of the front and rear joint receiving material 10. Then, the support portion 12a and the support portions 9a and 10a are locked by rivets or the like. When the front and rear ends are divided into three or more parts, the left and right joint receivers 12 other than the front and rear ends are placed on the support portions 10a of the front and rear joint receivers 10 and the support portions 12a The support portion 10a is locked by rivets or the like. However, although the case where the left and right joint receiving material 12 is divided into a plurality of pieces is shown here, the front and rear joint receiving material 10 can be divided into a plurality of pieces instead.

  Moreover, in the said embodiment, although the case where the translucent incombustible board 6 was a square netted glass was shown, since it should just be a translucent incombustible material which consists of an incombustible material which has translucency, it is like a netted glass. It is not limited to a flat plate shape, and may be a sheet shape, for example, and the shape is arbitrary depending on the installation location. Furthermore, as such a translucent incombustible material, a glass fiber sheet, an incombustible paper, etc. can be used. Moreover, even if the material itself does not have translucency, it has translucency by having a large number of gaps and through holes, such as a metal mesh sheet, expanded metal, punching metal, etc. It may be a thing. However, the material itself does not have translucency, but when using a metal mesh sheet, expanded metal, punching metal, etc. having a large number of gaps and through holes, a resin that is splattered or melted from these gaps or through holes. The material itself has a certain degree of translucency so that even if there is a gap, extremely fine glass fiber sheets or non-combustible papers are stacked on top and bottom, punching metal, etc. When the through holes are large, it is desirable to use them in combination by bonding or embedding a glass fiber sheet, non-combustible paper, or the like only in these through holes.

  Moreover, in the said embodiment, the latching | locking part 7a of the left side receiving material 7 is latched by the peak part 2a of the left end of the resin folded-plate roof material 4 in the tight frame 2, and the latching | locking part 8a of the right side receiving material 8 is tight frame. 2 shows a case where the resin folded plate roofing material 4 is locked to the peak 2a at the right end, but the lower side of the resin folded plate roofing material 4 only needs to be covered with the translucent incombustible plate 6. The locking portion 7 a of the material 7 is locked to the peak portion 2 a on the left side of the left end of the resin folded plate roof material 4 in the tight frame 2, and the locking portion 8 a of the right receiving material 8 is You may make it cover the range wider than the downward direction of the resin folded-plate roof material 4 with the translucent incombustible board 6 by latching to the peak part 2a of the right side rather than the right end of the board roof material 4.
