Description

The present invention belongs to the technical field of a manufacturing method of a building panel unit used when building a building structure such as a dome-shaped roof or a large span / span span roof, for example. The present invention relates to a method for manufacturing a building panel unit that can artificially introduce a film tension into a thin metal plate without depending on it.

  Conventionally, various building panel units have been developed in order to construct a building structure easily and lightly. The manufacturing method is disclosed in, for example, Patent Documents 1 to 3, and the metal thin plates forming the upper and lower surfaces are attached to the peripheral frame frame, or the outer peripheral edges of the metal thin plates are brought into contact with each other. After the outer shell is completed, a foamed resin is filled in the sealed space of the outer shell with a high pressure, and a membrane tension is introduced into the metal thin plate using a chemical reaction of the foamed resin.

JP 58-163635 A JP 60-101038 A JP 2003-206593 A

  The chemical reaction is difficult to control because it is greatly affected by the environment such as the type of foamed resin, the temperature at the time of filling, and the humidity. Therefore, the method of introducing film tension to the metal thin plate depending on the chemical reaction of the foamed resin as in the manufacturing methods described in Patent Documents 1 to 3 causes variations in quality and stabilizes the high-quality building panel unit. There is a problem that cannot be manufactured.

  By the way, when a typical two-component hard foamed urethane resin is considered as the foamed resin, the chemical reaction process from mixing the two stock solutions to curing is as shown in FIG. That is, if the filling operation is not completed within 20 seconds to 30 seconds, the foamed resin rapidly expands and cures, and the foamed resin may not reach all the corners of the metal sheet.

  On the other hand, the discharge capacity of a machine filled with foamed resin is generally about 100 N / min with a low-pressure machine.

Therefore, even if the filling time of the foamed resin is set to the longest 30 seconds, only a foamed resin of about 50 N (the volume is about 0.15 m ^{3 in} the foamed state) can be filled. As an example, the length of one side (L ) And the thickness (d) ratio is set to (d / L) = 0.021, a square panel unit has a side of about 2.0 m as is apparent from FIG. It is a limit.

  However, the manufacturing methods of Patent Documents 1 to 3 described above are manufactured as a single unit of a building panel unit in which filling of the foamed resin is completed at a time, and there is no technical idea to manufacture the assembly as an aggregate. , Can not be formed into large plates. Therefore, it was impossible to construct a large span building structure using the building panel unit manufactured by the manufacturing method of Patent Documents 1 to 3.

  The object of the present invention is to combine a pair of divided pieces so that foamed resins formed in a predetermined peeled shape are abutted with each other, or to sandwich an inclusion formed in a predetermined peeled shape. Incorporating a combination, and by introducing a certain film tension to the metal thin plate by the compressive force of the foamed resin extruded outward, the film tension is artificially introduced to the metal thin plate without depending on the chemical reaction of the foamed resin. It is possible to provide a method capable of stably manufacturing a high-quality building panel unit.

In this way, by combining and integrating the pair of divided pieces, the foamed resin is pushed outward, and a predetermined film tension is introduced into the upper and lower permanent metal sheets by the compressive force of the foamed resin. Therefore, the film tension can be artificially introduced into the upper and lower permanent metal sheets without depending on the chemical reaction.

  In particular, since the sealed space is formed by using a temporary thin plate or a formwork plate, the state of the foamed resin can be checked by removing the temporary thin plate or removing the formwork plate, or in a predetermined peeled shape. Easy to form. On the other hand, it is also easy to temporarily attach the temporary thin plate or place the mold plate and fill the foamed resin. Therefore, the foamed resin can be reliably distributed to every corner of the sealed space, and can be formed in a predetermined peeled shape.

  Therefore, a predetermined film tension can be reliably introduced to the upper and lower permanent metal sheets, and the foamed resin can be spread to every corner of the sealed space, so that a high-quality building panel unit can be stabilized. Can be manufactured.

An embodiment of a method for manufacturing a building panel unit according to the first, second, fifth, sixth and ninth aspects of the invention (hereinafter sometimes simply referred to as “manufacturing method”) is shown in FIG. This will be described with reference to FIG. In the manufacturing method according to the present invention, a building panel unit (hereinafter, sometimes simply abbreviated as a panel unit) 1 used when building a dome-shaped roof or a large span / large span roof building structure is constructed. It is preferably implemented for manufacturing.

  In order to prepare the two divided pieces 2 and 2 constituting the panel unit 1, first, two sets of peripheral frame frames 3 and 3 each having a thickness that is half of the outer peripheral thickness of the panel unit 1 are square (however, Is not limited to this), and the metal thin plate 4 for permanent installation is attached to one side of both, and the temporary thin plate 5 is temporarily attached to the other side to form a sealed space 6 (FIG. 1A). See). The temporary thin plate 5 is composed of a member that is softer and more easily deformed than the permanent metal thin plate 4 so that a peeled shape can be formed only on the temporary thin plate 5 side, and the foamed resin 7 is placed in the sealed space 6 later. For example, it is partially welded and temporarily attached to such an extent that sealing can be ensured when filled.

  The sealed space 6 is filled with the foamed resin 7, the temporary thin plate 5 is removed, the filled state of the foamed resin 7 is confirmed, the foamed resin 7 is spread to every corner of the sealed space 6, and a predetermined peeled shape is formed. (See FIGS. 1A and 1B, the invention according to claim 2). Specifically, the filling state of the foamed resin 7, that is, how the foamed resin 7 is spread or peeled off is confirmed, and when the foamed resin 7 has not yet spread to every corner of the sealed space 6 or from a predetermined peeled shape. If it is small, the temporary thin plate 5 is temporarily attached to the peripheral frame 3 again, and the sealed space 6 is filled with the foamed resin 7. On the other hand, if the foamed state of the foamed resin 7 is confirmed and the foamed resin 7 is larger than the predetermined peeled shape, the cured foamed resin 7 is shaved and the foamed resins 7 and 7 of the two divided pieces 2 and 2 are later removed. When they are butted and integrated, the preset film tension is corrected and adjusted so that it can be introduced into the upper and lower permanent metal thin plates 4 and 4 (inventions according to claims 5 and 6). Since the sealed space 6 is formed using the temporary thin plate 5 as described above, it is easy to remove the temporary thin plate 5 to check the filling state of the foamed resin 7 or to form a predetermined peeled shape. is there. On the other hand, it is also easy to temporarily attach the temporary thin plate 5 and fill the foamed resin 7. Therefore, the foamed resin 7 can be reliably distributed to every corner of the sealed space 6 and can be formed in a predetermined peeled shape.

  The two divided pieces 2 and 2 are combined so that the exposed surfaces of the foamed resins 7 and 7 face each other, and the peripheral frame frames 3 and 3 are joined together by bolts 8 and nuts 9 to be integrated (see FIG. 1 (C), (D) and FIG. 2). As a result, the butted foamed resins 7 and 7 are pushed outward, and a predetermined film tension is introduced into the upper and lower permanent metal thin plates 4 and 4 by the compressive force between the foamed resins 7 and 7. That is, the film tension can be artificially introduced to the upper and lower permanent metal thin plates 4 and 4 by the foamed resins 7 and 7 formed in a predetermined peeled shape.

  According to the manufacturing method described above, a predetermined film tension can be surely introduced into the upper and lower permanent metal thin plates 4, 4, and the foamed resin 7 can be spread to every corner of the sealed space 6. The high quality panel unit 1 can be manufactured stably.

  Further, since the panel unit 1 is configured as an assembly in which two divided pieces 2 and 2 are combined, the thickness of the divided piece 2 is set to half the outer peripheral thickness of the panel unit 1, and the width is increased accordingly. The large-sized panel unit 1 can be formed.

  Incidentally, since the material of the foamed resin 7 and the size of the peeled shape can be easily changed, the film tension introduced into the upper and lower permanent metal thin plates 4 and 4 can be easily adjusted artificially. (Invention of Claim 9).

  In this embodiment, the peeled shape of the foamed resin 7 is formed only on the temporary thin plate 5 side, but the peeled shape may be formed also on the permanent metal thin plate 4 side.

  In addition, as shown in FIG. 3, it is good also as the panel unit 11 with the bracing material 10 pinched | interposed and integrated between the upper and lower division pieces 2 and 2 and having high in-plane rigidity (invention of Claim 10). At this time, the end portion of the brace material 10 is accommodated in a recessed portion 3a formed in advance in the peripheral frame frame 3 so as not to cause a harmful effect when the upper and lower peripheral frame frames 3, 3 are joined.

  As shown in FIGS. 4 and 5, the partition material 12 is arranged and divided in the sealed space 6 of the divided piece 2, and the volume in which the foamed resin 7 spreads to every corner (that is, the foamed resin 7 is removed at a time). A plurality (four in the illustrated example) of cells 13 set in advance to the volume that can be filled may be formed.

  Specifically, the three partition members 12 are erected substantially vertically on one surface of the main sheet metal plate 4 so that the cell 13 having a preset volume can be formed by dividing the sealed space 6. . Similarly, on one surface of the temporary thin plate 5, three partition members 12 are set substantially vertically, and the permanent metal thin plate 4 and the temporary thin plate 5 are respectively surrounded so that the surfaces having the partition members 12 face each other. It is attached to the frame frame 3, and the upper and lower partition members 12, 12 are wrapped for a predetermined length. As a result, the partition material 12 is arranged in the frame surface of the peripheral frame 3, and four cells 13 are formed in the sealed space 5 with a preset volume.

  Although not shown, the peripheral frame 3 is provided with the filling port and the air vent in advance so as to arrange the filling port and the air vent in each cell 13. While filling the foamed resin 7 from the mouth, the air is removed from the air vent (the invention according to claim 8). Since each cell 13 has a volume that can be filled with the foamed resin 7 at a time, the foamed resin 7 can be spread to every corner of the cell 13, and the divided pieces 2 are further enlarged as an aggregate. Can be formed.

  Next, the Example of the manufacturing method of the panel unit for construction based on the invention described in Claim 3-5 and Claim 7, 9 is demonstrated based on FIGS. In the manufacturing method of the present embodiment, the inclusions 15 formed in a predetermined peeled shape are sandwiched and integrated between the divided pieces 14, 14, and a predetermined film tension is applied to the upper and lower metal thin plates 4, 4. It is characterized in that it is introduced (see FIG. 7 etc.).

  Specifically, in order to form the two divided pieces 14 and 14 in substantially the same manner as in the manufacturing method of the first embodiment, first, two sets of peripheral frame frames having a thickness that is half the outer peripheral thickness of the panel unit 16. 3 and 3 are assembled, the metal thin plate 4 is attached to one side of both sides, and the mold plate 17 is arranged on the other side to form a sealed space 18 (see FIG. 6A).

  The foamed resin 7 is filled in the sealed space 18 while applying pressure to the mold plate 17, the filled state of the foamed resin 7 is confirmed by removing the mold plate 17, and the foamed resin 7 is spread to every corner. To form a flat plate (see FIGS. 6A and 6B, inventions of claims 4 and 7). That is, after confirming the extent of the foamed resin 7, if the foamed resin 7 has not yet spread to every corner of the sealed space 18, the mold plate 17 is placed again and foamed in the sealed space 18 while applying pressure. The resin 7 is filled (the invention according to claim 5). Since the sealed space 18 is formed using the mold plate 17 as described above, the filling state of the foamed resin 7 can be easily confirmed by removing the same mold plate 17. On the other hand, when the mold plate 17 is disposed again, the foamed resin 7 can be easily filled.

  The two split pieces 14 and 14 are combined so that the inclusion 15 formed in a predetermined peeled shape is sandwiched between the exposed surfaces of the foamed resins 7 and 7, and the peripheral frame frames 3 and 3 are connected to each other by bolts 8. And the nut 9 are joined and integrated (see FIGS. 6C, 6D and 7). As a result, the foamed resins 7 and 7 are pushed outward, and a predetermined film tension is introduced into the upper and lower permanent metal thin plates 4 and 4 by the compressive force of the foamed resins 7 and 7. That is, by inserting the inclusion 15 formed in a predetermined peeled shape between the divided pieces 14 and 14, the film tension can be artificially introduced to the upper and lower permanent metal thin plates 4 and 4.

  In the manufacturing method of this embodiment, a predetermined film tension can be surely introduced into the upper and lower permanent metal thin plates 4 and 4, and the foamed resin 7 can be spread to every corner of the sealed space 18. The high quality panel unit 16 can be manufactured stably.

  Further, since the panel unit 16 is configured as an assembly in which the two divided pieces 14 and 14 are combined in substantially the same manner as in the first embodiment, the thickness of the divided piece 14 is equal to the outer peripheral thickness of the panel unit 16. The thickness is halved, and the width can be increased accordingly, and a large panel unit 16 can be formed.

  Incidentally, the inclusion 15 only needs to be made of a lightweight member. For example, when it is made of foamed resin 19, the peripheral frame frame 20 is assembled, and the temporary thin plates 21 and 21 are temporarily attached to the upper and lower surfaces thereof. A sealed space 22 is formed, and the foamed resin 19 is filled in the sealed space 22 (see FIG. 8A). Then, one or both of the temporary thin plates 21 are removed to check the extent of spreading or peeling of the foamed resin 19, and when the foamed resin 19 has not yet spread to every corner of the sealed space 22, or from a predetermined peeling shape. If it is smaller, the temporary thin plate 21 is temporarily attached to the peripheral frame frame 20 again, and the sealed space 22 is filled with the foamed resin 19. On the other hand, the filling state of the foamed resin 19 is confirmed, and if it is larger than the predetermined peeled shape, the size is adjusted by scraping the cured foamed resin 19. Finally, the inclusion 15 is completed when the peripheral frame 20 is removed (see FIG. 8B). Since the material of the inclusions 15 and the size of the peeled shape can be easily changed, the film tension introduced into the upper and lower permanent metal thin plates 4 and 4 can be easily adjusted artificially (invoice). Item 9).

  In this embodiment, the foamed resin 7 is filled in the sealed space 18 while applying pressure to the mold plate 17. However, if the weight plate is not heavy enough to float when the foam resin 7 is filled, In particular, it is not necessary to apply pressure. On the other hand, when the formwork plate 17 is light, the same formwork plate 17 may be temporarily attached to the peripheral frame frame 3 in the same way as the temporary thin plate 5 of the first embodiment. In short, the mold plate 17 only needs to be able to form the sealed space 18, and the material and arrangement method thereof are not particularly limited.

  In the present embodiment, the divided pieces 14 are formed in a flat plate shape, but may be formed in a peeled shape as in the first embodiment.

  As shown in FIG. 9, an inclusion 24 that penetrates the brace material 23 is formed, and the inclusion 24 is sandwiched and integrated by dividing pieces 14 and 14 to form a panel unit 25 having high in-plane rigidity ( (Invention of Claim 11) At this time, the end portion of the brace material 23 is housed in a recessed portion 3a formed in advance on the peripheral frame frame 3 in the same manner as in the second embodiment, and does not cause any adverse effects when the upper and lower peripheral frame frames 3, 3 are joined together. Like that.

  Also, as shown in FIGS. 10 and 11, a gap S is formed between the two divided pieces 14 and 14 by separating a plurality of inclusions 26 (divided into four along the diagonal line in this embodiment). Further, the brace member 27 may be disposed and sandwiched in the gap S and integrated with each other to form a panel unit 28 having high in-plane rigidity (the invention according to claim 12).

  The split pieces 2 and 2 (14 and 14) of the first embodiment and the like are joined by the bolt 8 and the nut 9, but may be joined by welding.

  The panel unit 1 (11, 16, 25, 28) according to the first embodiment is configured by combining two divided pieces 2, 2 (14, 14), but a plurality of divided pieces are joined. One large divided piece may be formed, and a pair may be prepared and combined.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments and can be implemented in various forms without departing from the gist of the present invention.
