Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel and a building construction method, and in particular, a roof panel attached prior to the installation of an outer wall panel in building construction, and a building construction method for installing an outer wall panel after the roof panel is installed. About.

  In order to improve work efficiency in building construction of a building, after building the building frame, roof construction, that is, installation of the roof panel, may be performed prior to installation of the outer wall panel. By preceding the roof construction in this way, it is possible to work under the roof even in the rain.

  On the other hand, a normal roof has an eaves side portion protruding outward. For this reason, if roof construction is preceded, there is a possibility of interference with the roof panel when the outer wall panel is suspended below the eaves portion of the roof in the subsequent installation work of the outer wall panel. As means for solving such a problem, for example, the methods of Patent Document 1 and Patent Document 2 can be cited.

  The roof unit described in Patent Document 1 has a removable eave part, a roof plate, and a support frame that supports the roof plate. If the eave portion is detachable as described above, the eave portion is removed when the outer wall panel is suspended, so that the outer wall panel (strictly, a hanging belt or a hanging wire hung on the outer wall panel, etc.) ) Can be prevented from interfering with the roof panel.

  The roof unit described in Patent Document 2 is configured such that an eaves unit separated from a main body portion of the roof unit is rotatably connected to the main body portion by a hinge. The eaves-end unit is rotated so as to jump upward and is placed on the main body. With such a configuration, if the eaves unit is rotated and placed on the main body when the outer wall panel is suspended, interference between the outer wall panel and the roof panel can be suppressed.

  By the way, in the roof part of a building, the load by wind blowing or snowfall is applied, and it becomes easy to apply especially to an eaves part, Therefore It is necessary to ensure the intensity | strength in an eaves part. On the other hand, in the roof unit described in Patent Document 1, a rafter that supports the roof panel is divided into an eave portion and another portion (rafter body) so that the eave portion can be attached and detached. For this reason, in the roof unit described in Patent Document 1, it is necessary to fasten the rafter body and the eaves portion by fastening means such as bolts when attaching the eaves portion. In such a configuration in which the rafters are divided, it is difficult to ensure the strength of the eaves portion. Moreover, when fastening the rafter main body and the eaves end portion firmly, a relatively large fastening material is used, and this may lead to a decrease in workability and an increase in cost.

  In addition, it is necessary to ensure the beauty of the roof of the building. On the other hand, in the roof unit described in Patent Document 2, since a hinge is used as a connecting means between the eaves unit and the main body, the hinge may affect the appearance of the roof unit.

Then, this invention is made | formed in view of said subject, The place made into the objective is the roof panel which does not prevent installation of an outer wall panel and can ensure the construction quality of a roof part. Is to provide.
Another object of the present invention is to smoothly install the outer wall panel while ensuring the construction quality of the roof part when the roof panel is installed prior to the installation of the outer wall panel as a building construction method. Is to provide a construction method that is possible.

According to the roof panel of the present invention, the subject is used for constructing a roof portion of a building, and is placed on a support member that extends toward the eaves in the roof portion of the building. A roof panel, a panel tip located on the eaves side in the roof panel, a panel body forming a portion other than the panel tip in the roof panel, and attached to a lower part of the panel tip, A fitting part that fits into a support material tip located on the eaves side in the support material, and the panel tip part is separate from the panel body, and the fitting part and the It is removed from the panel main body by releasing the fitting state with the support material tip, and the fitting portion is the rafter as the support material, as the support material tip portion located closest to the eaves side. Fits at the rafter tip A square tubular body, angular tubular body is solved by Rukoto have a through hole corresponding to the shape of the cross section of the rafter tip perpendicular to the extending direction of the rafters.

  In the above roof panel, the panel front end located on the eaves side is separate from the panel main body, and the panel front end and the panel main body constitute the roof panel. And the fitting part attached to the lower part of the panel tip part releases the state fitted to the support material tip part located on the eaves side in the support material that supports the roof, so that the panel tip part is the panel body It comes to come off. In such a configuration, when the outer wall panel is suspended, the front end of the panel is removed, so that the outer wall panel (strictly speaking, a hanging belt or a hanging wire hung on the outer wall panel) is separated from the roof panel. It is possible to suppress interference. On the other hand, in the above configuration, only the roof panel is divided, and the support material that supports the roof panel is not divided. For this reason, in the roof part constructed | assembled using said roof panel, it becomes possible to ensure the intensity | strength in the eaves part. Furthermore, since the connection between the panel tip and the panel body is realized by fitting the fitting part attached to the lower part of the panel tip to the support material tip, a hinge or the like is used as the connection means. In comparison, it is possible to suppress the influence of the connecting means on the beauty of the roof panel.

Further, by the above-described roof panel lever, by insertion of the square tubular body of the fitting portion with respect to the rafter tip, it is possible to perform attachment and detachment of the panel tip relative panel body easily.

  In addition, according to the building construction method of the present invention, the above-described problem includes a step of building a roof portion of a building using a roof panel, and a step of building an outer wall portion using an outer wall panel. In the construction method, in the step of constructing the roof part, (A) on the support member extending toward the eaves in the roof part in the building body, (a1) in the roof panel A front end of the panel located on the eaves side, (a2) a panel body forming a portion other than the front end of the panel in the roof panel, and (a3) attached to a lower part of the front end of the panel, And (B) the step of constructing the outer wall portion, in the step of constructing the outer wall portion, the front end of the panel forming a separate body from the panel main body. Part is the fitting The panel body is removed from the panel body by releasing the fitting state between the portion and the support material tip, and only the panel body of the panel body and the panel tip is placed on the support material. In the meantime, the problem is solved by suspending the outer wall panel toward the lower position of the support material tip.

  In the building construction method described above, of the roof panel, the panel front end located on the eaves side is removed from the panel main body, and among the panel main body and the panel front end, only the panel main body is placed on the support material. In the meantime, the outer wall panel is suspended toward the lower position of the tip of the support member. As a result, when the outer wall panel is suspended, it is possible to prevent the suspension belt, the hanging wire, etc. hung on the outer wall panel from interfering with the roof panel, and as a result, the outer wall panel can be installed smoothly. Become. Moreover, when removing the panel front-end | tip part from a panel main body, what is necessary is just to cancel | release the fitting state of a fitting part and a support material front-end | tip part, and it is not necessary to divide a support material. For this reason, it becomes possible to suppress that the intensity | strength in an eaves part falls among roof parts by parting of a support material. In other words, if it is the construction method of said building, it will become possible to ensure the intensity | strength in the said eaves part. Furthermore, since the connection between the panel tip and the panel body is realized by fitting the fitting part attached to the lower part of the panel tip to the support material tip, a hinge or the like is used as the connection means. In comparison, it is possible to suppress the influence of the connecting means on the beauty of the roof panel.

In the building construction method described above, the step of constructing the roof portion includes the step of constructing the fitting portion into the support material front end portion before performing the step of constructing the outer wall portion. After performing the first step of placing the roof panel in a state where the front end of the panel is assembled to the panel main body on the support member and the step of constructing the outer wall portion, the fitting portion is It is good also as having a 2nd process of reassembling the said panel front-end | tip part removed from the said panel main body to the said panel main body by fitting to a support material front-end | tip part.
According to the above method, the roof portion is constructed before the outer wall portion is constructed, and during the period of constructing the outer wall portion, the panel tip of the roof panel is removed from the panel body, and after the outer wall portion is constructed. Reassemble the panel tip to the panel body again. That is, according to the start / end of the process of constructing the outer wall portion, it is possible to appropriately switch the attachment / detachment state of the panel tip portion with respect to the panel body. Thereby, the building construction of the building in which the installation of the roof panel is performed prior to the installation of the outer wall panel proceeds more smoothly.

In the building construction method, the first step is performed in a work place different from the building site of the building, and the roof panel in a state where the panel tip is assembled to the panel body is mounted. It is good also as having the process of conveying the said support material set | placed to the said construction site from the said working place, and the process of incorporating the said conveyed support material in the said housing in the said construction site.
According to the above method, the work of placing the roof panel on the support material is performed at a place other than the construction site, and for easy understanding, the roof portion of the building is internally produced at the work site away from the construction site, and is applied to the construction site. Will be transported the assembled roof. As a result, the amount of work at the construction site is reduced, and the work period can be shortened accordingly.

In the building construction method described above, the step of constructing the outer wall portion includes the step of incorporating the support material into the housing, and then the fitting state between the fitting portion and the front end portion of the support material. The third step of removing the panel tip from the panel body by releasing, and only the panel body out of the panel body and the panel tip is placed on the support member, A fourth step of suspending the outer wall panel toward a lower position, and in the fourth step, the front end of the panel is positioned when the step of incorporating the support material into the housing is completed. A tension member stretched between the outer wall panel and the suspension tool may be inserted into the space, and the outer wall panel may be suspended toward the lower position.
According to the above method, when the outer wall panel is suspended, the tension member hung on the outer wall panel is inserted into the space where the front end of the panel is located immediately before being detached from the panel body. Thereby, an outer wall panel comes to be appropriately suspended toward the downward position of a support material front-end | tip part.

In the building construction method described above, the step of constructing the roof portion may include the step of fastening the free end portion of the fastener attached to the front end portion of the panel to the panel body after performing the second step. While fastening a panel front-end | tip part and the said panel main body, the free end part of the other fastener attached to the said fitting part is fastened to the said support material front-end | tip part, and the said fitting part and the said support material front-end | tip part are attached. It is good also as having the process of fastening.
According to said method, the panel front-end | tip part reassemble | attached to the panel main body after installing an outer wall panel, and a panel main body are fastened with a fastener. Thereby, it is suppressed that a panel main body will remove | deviate from a panel main body after completion | finish of a construction work, Therefore, a roof panel comes to exhibit the function favorable.

  According to the roof panel of the present invention and the building construction method of the present invention, in the case where the installation of the roof panel is performed prior to the installation of the outer wall panel, the outer wall panel can be smoothly made while ensuring the construction quality of the roof portion. It becomes possible to install. Such an effect makes it possible to further shorten the construction period of the building construction of the building and improve the work efficiency in the construction.

  Hereinafter, an embodiment of the present invention (hereinafter, this embodiment) will be described with reference to the drawings. Note that the drawings are somewhat simplified for convenience of explanation, and are slightly different from actual structures and sizes.

  Hereinafter, a house (strictly, a detached house) will be described as an example of a building. However, a house is only an example of a building, and the present invention can be applied without limitation as long as the roof eaves are overhanging, for example, a building, a facility, a store, etc. in a factory. It is possible. Moreover, in the following description, an eaves part means the part which protruded outside the outer wall part of the building among roof parts.

  The house 1 according to the present embodiment has the same appearance as a general detached house having the appearance shown in FIG. 1 and having an inclined roof. Moreover, the frame 4 of the house 1 employs a steel structure, and a rafter 5 for supporting the roof panel 8 is disposed in a portion of the frame 4 corresponding to the roof part 2 of the house 1. This rafter 5 corresponds to a support material, extends toward the eaves in the roof portion 2 of the house 1, and supports the roof panel 8 placed thereon. A plurality of rafters 5 are arranged at regular intervals along the girder direction of the house 1, that is, the extending direction of the purlin 7A. Further, the cross-sectional shape of the rafter 5 (strictly, the cross-sectional shape orthogonal to the extending direction) is substantially rectangular.

  The roof panel 8 is a field plate, and a plurality of roof panels 8 are used in configuring the roof portion 2. Each roof panel 8 is disposed across the plurality of rafters 5 in the girder direction. And each of the roof panel 8 which concerns on this embodiment is comprised from the two panel pieces which make a different body mutually, as shown in FIG. That is, in this embodiment, each roof panel 8 is configured by connecting the two panel pieces.

  The two panel pieces constituting each roof panel 8 will be described. One of them is a panel front end portion 9 located on the eaves side of the roof panel 8, and this panel front end portion 9 has completed the construction of the house 1. At this point, it projects outward from the outer wall 3. The other is a panel body 10 that constitutes a portion of the roof panel 8 other than the panel tip 9 and is disposed between the purlin 7A and the eaves 7B.

  In addition, as shown in FIG. 2, in each roof panel 8, a rectangular tube body 11 as a fitting portion is attached to the lower portion of the panel front end portion 9. The rectangular tube 11 is fitted to the rafter tip 6 (corresponding to the support tip) located on the eaves end side of the rafter 5. More specifically, the rectangular tube body 11 includes a through hole 12, and the outer edge of the through hole 12 has a substantially rectangular shape corresponding to the cross-sectional shape of the rafter tip 6 perpendicular to the extending direction of the rafter 5. The size is substantially the same as the cross-sectional shape of the rafter tip 6. With such a structure, the rectangular tube 11 can be inserted into and removed from the rafter tip 6.

  And the panel front-end | tip part 9 will connect with the panel main body 10, and the one roof panel 8 will be constructed | assembled, when the square cylinder 11 fits into the rafter front-end | tip part 6. FIG. In other words, the panel tip 9 can be removed from the panel body 10 by releasing the fitting state between the rectangular tube 11 and the rafter tip 6.

  In addition, as shown in FIG. 2, a plurality of rectangular cylinders 11 are attached to the lower surface of the panel front end portion 9 of each roof panel 8 at regular intervals along the girder direction. Of the plurality of rafters 5 that are placed across the roof panel 8, the rafters 5 of the corresponding rafters 5 are to be fitted.

  The house 1 of the present embodiment in which the roof portion 2 is constructed by the roof panel 8 described above can be constructed in a relatively short construction period by utilizing the characteristics of the roof panel 8 described above. Hereinafter, the construction method of the house 1 according to the present embodiment will be described.

  The construction method of the house 1 according to the present embodiment is employed in the construction work of the house 1. The flow of such construction work will be outlined. After the building construction work including the foundation work is completed, the installation of the roof panel 8 is performed prior to the installation of the outer wall panel 13. This is to take advantage of the advantage that the roof panel 8 is installed immediately after the completion of the housing 4 so that the work can be performed under the roof even if it rains after that. Further, when the roof panel 8 is installed after the outer wall panel 13 is installed, there is a possibility that rainwater may enter the outer wall panel 13 if it rains during that time. The above problem can be avoided if the operation is performed before the installation of the outer wall panel 13.

  On the other hand, after the roof panel 8 is installed, the outer wall panel 13 is installed at a predetermined position to construct the outer wall portion 3. Here, the position where the outer wall panel 13 is installed is below the eaves (strictly, a position slightly behind the lower position of the rafter tip 6). As shown, the outer wall panel 13 is suspended toward the lower position of the rafter tip 6. At this time, if the roof panel 8 is already installed, a suspension belt 16 (stretching member) stretched between the outer wall panel 13 and a suspension hook 17 (an example of a lifting tool) to suspend the outer wall panel 13. May interfere with the roof panel 8, particularly the eaves portion.

  As a method for avoiding interference with the eaves portion of the roof portion 2 when the outer wall panel 13 is suspended, for example, a guide or a jig projecting outward from the eaves portion at the lower position of the eave portion of the roof portion 2 can be used. A construction method is conceivable in which a tool is installed and the outer wall panel 13 is submerged below the eaves portion using the tool. However, since it is necessary to secure a space for installing the above guides and jigs, it is difficult to adopt the above construction method in a narrow area where the interval between adjacent houses is narrow.

  On the other hand, in the house 1 according to the present embodiment, it is possible to easily avoid interference with the eaves portion of the roof portion 2 during the suspension of the outer wall panel 13 by using the structure of the roof panel 8 described above. Is possible. That is, in this embodiment, since the panel front-end | tip part 9 of the roof panels 8 is comprised so that removal is possible with respect to the panel main body 10, the said panel front-end | tip part 9 should be removed when the outer wall panel 13 is suspended. Thus, it is possible to avoid interference between the suspension belt 16 hung on the outer wall panel 13 and the roof panel 8.

  In the present embodiment, the panel tip 9 can be easily attached to and detached from the panel main body 10 by inserting and removing the rectangular tube 11 with respect to the rafter tip 6. Moreover, in this embodiment, in order to be able to remove the eaves part of the roof part 2 (specifically, the panel front-end | tip part 9 of the roof panel 8), while dividing | segmenting the roof panel 8 into two panel pieces, The rafter 5 that supports the panel 8 is not divided. Thus, since only the roof panel 8 is divided without dividing the rafter 5, the strength at the eaves portion of the roof portion 2 is appropriately secured.

  Further, when a hinge is used to connect the panel tip 9 and the panel body 10, the hinge is exposed on the surface of the roof panel 8, or the hinge is interposed between the panel tip 9 and the panel body 10. For example, a gap is formed between the panel front end portion 9 and the panel body 10. On the other hand, by fitting the rectangular tube 11 to the rafter tip 6, the panel tip 9 is connected to the panel body 10, and the square tube 11 is attached to the lower surface of the panel tip 9. ing. That is, in the present embodiment, the rectangular tube 11 that is a connecting means between the panel front end portion 9 and the panel main body 10 is provided at a position that is less noticeable. Therefore, this embodiment can suppress the influence which the said connection means has on the beauty | look of the roof panel 8 compared with the case where a hinge is used as a connection means.

  Next, from among the construction work of the house 1 according to the present embodiment, the roof construction that constructs the roof portion 2 using the roof panel 8 and the outer wall construction that constructs the outer wall portion 3 using the outer wall panel 13. explain in detail. Roof construction and outer wall construction proceed according to the procedure illustrated in FIG. If it demonstrates concretely, it will start from the process of making the roof part 2 as a unit (S001). This step S001 corresponds to the first step and is performed before the outer wall construction as part of the roof construction.

  In the present embodiment, the in-house work of the roof portion 2 is performed at a work place different from the construction site of the house 1, specifically, a building material production factory. In this in-house work, a portion corresponding to the roof portion 2 is assembled in the frame 4 and the roof panel 8 is placed on the rafter 5. That is, in the internal work according to the present embodiment, the internal work of the roof portion 2 is performed at the building material production factory up to the place where the roof panel 8 is installed. At this time, the rectangular tube 11 is fitted to the rafter tip 6 and the panel tip 9 is assembled to the panel body 10. That is, at the stage of in-house work, the roof panel 8 in a state where the panel front end portion 9 and the panel main body 10 are connected is placed on the rafter 5 and supported.

  When the internal work is completed, the roof frame 2 including the rafter 5 on which the roof panel 2 with the roof panel 8 in a state in which the panel tip portion 9 is assembled to the panel body 10 is created. It is transported from the factory to the construction site of the house 1 (S002). At this time, in the construction site of the house 1, a part of the housing 4 of the house 1 excluding the part corresponding to the roof part 2 has already been constructed.

  And after the roof part 2 arrives at a construction site, the rafter on which the roof part 2 (that is, the roof panel 8 in the state in which the panel front-end | tip part 9 was assembled | attached to the panel main body 10) was mounted in the said construction site. (Roof frame including 5) is incorporated into the frame 4 (S003). Thus, in this embodiment, the operation | work which mounts the roof panel 8 on the rafter 5 is performed in places other than a construction site, and the assembled roof part 2 will be conveyed by the construction site. As a result, the amount of work at the construction site can be reduced, and the work period can be shortened accordingly.

  After the building 4 is constructed, outer wall work will be performed. Such outer wall construction starts from removing the panel tip 9 from the panel body 10 (S004). That is, when starting the outer wall construction, first, the fitting state between the rectangular tube 11 and the rafter tip 6 is released, and the panel tip 9 of the roof panel 8 is removed. This step S004 corresponds to the third step and is performed as part of the outer wall construction. And by removing the panel front-end | tip part 9, the eaves part of the roof part 2 will be in the state in which the rafter 5, strictly speaking, the rafter front-end 6 is exposed as shown in FIG. Of the front end portion 9 and the panel main body 10, only the panel main body 10 is placed.

  After removing the panel tip 9 from the panel body 10, the outer wall panel 13 is suspended and installed (S005). This step S005 corresponds to the fourth step, and only the panel main body 10 out of the panel front end portion 9 and the panel main body 10 is placed on the rafter 5 by removing the panel front end portion 9 from the panel main body 10. Between. When the outer wall panel 13 is suspended, one end of the suspension belt 16 is hung on the outer wall panel 13 via an attachment jig. Thereafter, the outer wall panel 13 is lifted by a suspension hook 17 on which the other end of the suspension belt 16 is hung, and is suspended toward a position below the rafter tip 6. In the present embodiment, the suspension belt 16 is used as an example of the tension member used to suspend the outer wall panel 13, but the present invention is not limited to this, and a suspension wire may be used.

  Further, when the outer wall panel 13 is suspended toward the lower position of the rafter tip 6, as shown in FIG. 5, the suspension belt 16 is inserted into the space where the panel tip 9 is originally positioned, so that the outer wall panel 13. Is suspended toward the lower position of the rafter tip 6. Here, the space where the panel front end portion 9 is originally located is a space where the panel front end portion 9 is located when the step of incorporating the roof portion 2 into the casing 4 (S002) is completed. Is a space located between the rafter tips 6. Further, the suspension belt 16 entering the space where the panel tip 9 is originally located means that the suspension belt 16 passes through the space located between the rafter tips 6 adjacent to each other as shown in FIG. That is.

  When the outer wall panel 13 finally reaches a position below the rafter tip 6 and is located slightly behind the rafter tip 6, the outer wall panel 13 is installed at that position. As a method for installing the outer wall panel 13, a known installation method can be applied. And when installation of all the outer wall panels 13 is completed, outer wall construction is complete | finished.

  After the outer wall work is completed, the roof work is resumed. Specifically, a process of reassembling the panel tip 9 that has been removed from the panel body 10 to the panel body 10 is performed (S006). This step S006 corresponds to the second step and is performed as part of the roof construction. In reattaching the removed panel tip 9 to the panel body 10, the rectangular tube 11 is fitted to the rafter tip 6, and the panel tip 9 is joined to the panel body 10. In a state where the panel front end portion 9 is joined to the panel main body 10, the upper surface of the panel front end portion 9 and the upper surface of the panel main body 10 form a continuous plane.

  As described above, the front end portion 9 of the panel that has been removed from the panel body 10 at the start of the outer wall work is assembled to the panel body 10 again after the outer wall work is completed. That is, in this embodiment, it is possible to appropriately switch the attachment / detachment state of the panel front end portion 9 with respect to the panel body 10 according to the progress of the outer wall construction. As a result, the roof panel 8 is restored to its original shape after the outer wall work is completed, and the roof portion 2 of the house 1 also has an eaves portion. Henceforth, the roof panel 8 is the same as a general roof portion. The function of will be demonstrated.

  In the present embodiment, the panel tip 9 is removed from the panel body 10 at the start of the outer wall construction. However, it is only necessary that the panel tip 9 is removed from the panel body 10 at least when the outer wall panel 13 is suspended. . For example, the panel tip 9 has already been removed from the panel body 10 at the time of making the roof 2 in-house, and the roof 2 is transported while the panel tip 9 is removed from the panel body 10. It is good also as incorporating the roof part 2 in the housing 4.

  After the panel tip 9 is reassembled with respect to the panel body 10, both fasteners are used with a predetermined fastener as shown in FIGS. The connection state of the panel pieces is maintained. More specifically, after assembling the panel front end portion 9 to the panel main body 10, the free end portion 14 a of a fastening member 14 as a fastener attached to the panel front end portion 9 is fastened to the panel main body 10 to fix the panel front end. The part 9 and the panel body 10 are fastened (S007). Here, the fastening member 14 can be used without particular limitation as long as it fastens two panel pieces. Incidentally, the fastening bracket 14 shown in FIG. 6 is made of a metal plate, and one end of which is screwed to the panel tip 9. Further, as shown in the figure, the other end of the fastener 14, that is, the free end 14 a is bent in an L shape. When fastening the panel front-end | tip part 9 and the panel main body 10, the free end part 14a bent in this L shape is struck into the panel main body 10, and it is made to bite.

  Further, when fastening the panel tip 9 and the panel body 10, the above-described fastening metal fitting 14 is used, and as shown in FIG. 7, other fastenings as other fasteners attached to the rectangular tube body 11. The free end 15 a of the metal fitting 15 is fastened to the rafter tip 6. That is, in this embodiment, when the panel front-end | tip part 9 and the panel main body 10 are fastened, it is supposed that the square cylinder 11 and the rafter front-end | tip part 6 will be fastened together. Thereby, it becomes possible to fasten the panel front-end | tip part 9 and the panel main body 10 more firmly.

  In addition, about the other fastening bracket 15, if the square cylinder 11 and the rafter front-end | tip part 6 are fastened, it can utilize without a restriction | limiting especially. Incidentally, the other fastener 15 illustrated in FIG. 7 is formed of a claw-shaped metal piece, and one end of the both ends thereof is fixed to the rectangular tube body 11 by welding or the like. Moreover, as shown in the figure, the other end part of the other fastener 15, that is, the free end part 15a is bent in an L shape. When the rectangular cylinder 11 and the rafter tip 6 are fastened, the free end 15a bent in an L shape is struck into the rafter tip 6 and bitten. It should be noted that the rectangular tube 11 and the other fasteners 15 may be formed by separately joining them by welding or the like, or may be integrally formed. Good.

  Up to this point, the roof panel and the building construction method of the present invention have been described by taking one specific embodiment as an example. However, the above embodiment is for facilitating understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof.
