Description

[Technical Field]

[0001] The present invention relates to an end processing structure for a folded plate roof during construction. [Background technology]

[0002] In buildings with large spaces, the roof structure is often a folded-plate roof supported by a steel roof frame. Patent Document 1 describes an example of a method for constructing a folded-plate roof for such a building. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-134541 Summary of the Invention [Problem to be solved by the invention]

[0004] When constructing the roof structure of a building with a large space, due to process reasons, the folded-plate roof may remain in a partially covered state for a relatively long period of time during construction. In such cases, a problem arises in that the completed folded-plate roof may be subjected to strong wind blow-up forces. In particular, during strong winds such as typhoons, there is a risk of the folded-plate roof collapsing due to the blow-up force. In addition, when the roof is in a partially covered state, measures must be taken to prevent flooding due to rainfall and scattering due to strong winds.

[0005] The present invention has been made in consideration of the above problems, and aims to provide an end processing structure for a folded plate roof that can resist the blow-up force of a folded plate roof that occurs in a half-roof state. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides an end treatment structure for an end portion on the remaining section side of a folded plate roof in a roof structure having a folded plate roof supported by a roof steel frame, where the folded plate roof has been constructed in a partial section and the remaining section of the folded plate roof continuous with the partial section has not been constructed. The folded plate roof has folded plates attached to a tight frame provided on the roof steel frame, and a temporary folded plate member is provided so as to be continuous from the folded plate in the partial section to the remaining section side, and the temporary folded plate member is attached to the tight frame in the remaining section. It is an end treatment structure of a folded plate roof, characterized in that.

[0007] In the present invention, in a semi-roof state where only the folded plate roof in a partial section has been constructed, a temporary folded plate member is provided so as to be continuous from the folded plate in the partial section to the remaining section side, and this is attached to a tight frame provided on the roof steel frame. Thereby, it is possible to resist the uplifting force of the folded plate roof generated in the semi-roof state and prevent breakage from the end of the folded plate roof. In addition, the temporary folded plate member is also effective as a water intrusion countermeasure by extending in a gable shape toward the remaining section (the unconstructed section of the folded plate roof).

[0008] At the end portion, it is desirable that a mounting fitting is provided on the folded plate, and the mounting fitting and the roof structure in the remaining section are connected by a linear connecting member. By connecting a mounting fitting provided on the folded plate in a partial section and the roof structure in the remaining section using a linear connecting member, it is possible to resist the uplifting force of the folded plate roof generated in the semi-roof state, and even if breakage occurs from the end of the folded plate roof, it is possible to prevent the collapse of the folded plate roof. In addition, by using a wire material such as a chain as the connecting member, it is possible to easily attach the mounting fitting in the partial section and the roof structure in the remaining section.

[0009] It is desirable that the connecting member is passed through the peak portion of the tight frame in the remaining section. The linear connecting member is preferable because it can be easily attached on the remaining section side just by passing it through the peak portion of the tight frame.

[0010] The folded-plate roof has a double-folded-plate structure formed by upper and lower folded plates. The upper folded plate is attached to a fixing member fixed to the lower folded plate. It is also preferable that the mounting bracket is provided on the fixing member via the upper folded plate above. By providing the mounting bracket on the above-mentioned fixing member, even if the fixing member breaks accidentally due to the uplifting of the folded-plate roof, its scattering can be prevented.

[0011] The folded-plate roof has a double-folded-plate structure formed by upper and lower folded plates. At the end portion, it is desirable to provide a cover material for preventing water from entering between the upper and lower folded plates. Further, a plate-shaped ceiling material is suspended and supported from the folded-plate roof, and at the end portion, it is desirable to provide a cover material for preventing water from entering between the folded-plate roof and the ceiling material. With these cover materials, it is possible to prevent water from entering between the upper and lower folded plates and between the folded-plate roof and the ceiling material.

[0012] The folded-plate roof has a configuration in which field plates are arranged at intervals on the folded plates, a sheet-shaped waterproof material is provided on the field plates, and a roof plate is provided on the waterproof material. It is desirable that the waterproof material of the folded-plate roof in a partial section extends from the field plate to the remaining section side and hangs down to the side of the lower folded plate. Thereby, water ingress between the waterproof material and the field plate can be prevented by a simple method of extending the waterproof material.

[0013] The folded-plate roof has a configuration in which field plates are arranged at intervals on the folded plates and a roof plate is provided on the field plates. It is desirable to provide a pressing member for pressing the roof plate of the folded-plate roof in a partial section from above. With the above-mentioned pressing member, it is possible to prevent the roof plate from scattering due to strong winds or the like.

Advantages of the Invention

[0014] According to the present invention, it is possible to provide an end treatment structure of a folded-plate roof that can resist the uplifting force of the folded-plate roof generated in a semi-roof state, and the like.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0017] (1. Arena Structure 1) FIG. 1 is a diagram showing an overview of the arena structure 1 to which the end treatment structure of the folded plate roof according to the embodiment of the present invention is applied during construction.

[0018] The arena structure 1 is provided with spectator seats 2 so as to surround the column-free arena space S, and a roof steel frame 10 is spanned between the outer peripheral steel frames 3 provided around the spectator seats 2, and the folded plate roof 7 is supported by the roof steel frame 10. The roof steel frame 10 and the folded plate roof 7 constitute the roof structure 100 of the arena structure 1.

[0019] FIG. 2 is a diagram showing the plan of the roof steel frame 10 with a part of the folded plate roof 7 of the arena structure 1 omitted.

[0020] As shown in Fig. 2, the roof steel frame 10 has steel beams 4, 5 and diagonal members 6. The arena structure 1 has a substantially elliptical plane, and the steel beam 4 is arranged in the short side direction of the plane. The steel beam 5 is arranged in the long side direction of the plane of the arena structure 1. Note that Fig. 1 shows the arena structure 1 along the short side direction of the plane of the arena structure 1, that is, the span direction of the steel beam 4.

[0021] In the arena structure 1, a plurality of steel beams 4 are arranged in parallel, and similarly, a plurality of steel beams 5 are arranged in parallel. These steel beams 4, 5 intersect in the plane. In the example of Fig. 2, the steel beams 4, 5 are orthogonal. The diagonal member 6 is arranged obliquely with respect to the steel beams 4, 5 in the plane.

[0022] As shown in Fig. 1, the steel beam 4 is a truss beam having an upper chord member 41, a lower chord member 42, a diagonal member 43, and a bundled member 44. Similarly, the steel beam 5 is also a truss beam having an upper chord member, a lower chord member, a diagonal member, and a bundled member. The steel beams 4, 5 are formed of steel members such as H-shaped steel. In the roof steel frame 10, the steel beams 4, 5 are combined so that the bundled member 44 of the steel beam 4 and the bundled member of the steel beam 5 become the same member. That is, one vertical member is used as the bundled member of both steel beams 4, 5. However, there may be a case where the bundled member 44 of the steel beam 4 and the bundled member of the steel beam 5 are separate members. [[ID=]10]

[0023] (2. Construction Procedure of Roof Steel Frame 10 and Folded Plate Roof 7) The construction of the roof steel frame 10 is started after at least the construction of the outer peripheral steel frame 3 and before the construction of the folded plate roof 7. Fig. 3 is a view showing the state during the construction of the roof steel frame 10 along the construction direction A of the roof steel frame 10. In the present embodiment, the construction direction A of the roof steel frame 10 corresponds to the span direction of the steel beam 5.

[0024] The roof steel frame 10 is constructed while being supported by the support portion 81 provided on the vent 8. As shown in FIG. 4(a), the support in the support portion 81 is performed by supporting the block material 813 provided on the lower surface of the roof steel frame 10 with the girder receiving fitting (girder receiving member) 812 provided at the top of the vent 8. The reference numeral 811 in FIG. 4(a) is a jack used in a later process. In FIG. 1, the position where the vent 8 is provided is indicated by a chain line.

[0025] In this embodiment, at least until the construction of the entire roof steel frame 10 is completed, the (maximum) vertical load acting on the roof steel frame 10 is assumed in advance, and the steel girder 4 is designed so that the vertical load can be supported only by the steel girder 4. The vertical load is, for example, the sum of the self-weight of the roof steel frame 10 and the weights of accessories of the roof steel frame 10 (equipment, ceiling boards, roof bases, temporary materials, etc. not shown). In short, the steel girder 4 is designed so that these weights can be supported even if the steel girder 5 and the diagonal members 6 do not exist.

[0026] Although the steel girder 5 has the effect of dispersing the vertical load and the effect of supporting the vertical load, it means that these effects are not exerted, or even if they can be exerted, the vertical load can be supported by the steel girder 4 without considering this, and the structure is established only by the steel girder 4 during the construction of the roof steel frame 10. After the construction of the roof steel frame 10 is completed, redundancy by the steel girder 5 is ensured with respect to the support of the vertical load.

[0027] And in this embodiment, during the construction of the roof steel frame 10, for the first range 10-1 which is a predetermined length range along the construction direction A from the start end (the right end in FIG. 3) of the construction direction A, the jack-down of the constructed roof steel frame 10 is performed. Note that the position until which the construction of the roof steel frame 10 is completed and then the jack-down of the roof steel frame 10 in the first range 10-1 is performed is determined by the structural analysis result of the target structure and the like, and is not particularly limited.

[0028] As shown in Fig. 4(a), the jack-down is performed by extending the jack 811 as shown in Fig. 4(b) to transfer the load of the roof steel frame 10 from the girder support fitting 812 to the jack 811, and then gradually contracting the jack 811 while removing the girder support fitting 812 from the top as shown in Fig. 4(c).

[0029] Even when the roof steel frame 10 in the first range 10-1 is jacked down, the construction of the roof steel frame 10 in the second range 10-2 that follows the first range 10-1 in the construction direction A can continue. Also, in the first range 10-1, after the roof steel frame 10 is jacked down, roof work for laying the folded plate roof 7 is started on the roof steel frame 10, and as shown in Fig. 5, the construction of a partial section 7-1 of the folded plate roof 7, which is a section of a predetermined length along the construction direction A from the outer peripheral steel frame 3, is completed.

[0030] When the construction of the roof steel frame 10 in the second range 10-2 is completed, the roof steel frame 10 in the second range 10-2 is jacked down. After the jack-down, roof work for laying the folded plate roof 7 is started for the remaining section 7-2 where the folded plate roof 7 has not been constructed. The remaining section 7-2 is a section that is continuous with the above partial section 7-1 in the construction direction A.

[0031] (3. End treatment structure of the folded plate roof 7) In this embodiment, after the construction of the folded plate roof 7 in the partial section 7-1, until the roof steel frame 10 in the second range 10-2 is jacked down and the roof work for the remaining section 7-2 is started, end treatment of the folded plate roof 7 is performed for the purpose of preventing the folded plate roof 7 in the semi-roof state from being blown up, preventing water from entering, and preventing scattering. In the following description, the side of the remaining section 7-2 as seen from the folded plate roof 7 in the partial section 7-1 may be referred to as "front", and the opposite side may be referred to as "rear".

[0032] Fig. 6 is a diagram showing the end treatment structure of the folded plate roof 7, and shows a cross-section in the thickness direction of the folded plate roof 7 along the span direction of the steel girder 5 for the front end of the folded plate roof 7 in the partial section 7-1.

[0033] As shown in Fig. 6, the folded plate roof 7 includes folded plates 71a, 71b, a heat insulating material 72, heat insulating metal fittings 73, connecting metal fittings 74, connecting fittings 75, a field board 76, a waterproof material 77, a buffer material 78, a roof board 79, etc.

[0034] The folded plate 71a is a corrugated steel plate having a plurality of valleys and ridges. The folded plate 71a is attached onto the tight frame 12 provided on the roof steel frame 10.

[0035] The tight frame 12 is a strip-shaped metal member having a plurality of valleys and ridges, and is fixed to the roof steel frame 10 (the upper chord member of the steel frame beam 5) via a receiving member 11, and is arranged along the span direction of the steel frame beam 5. A clamping metal fitting 61a is attached to the top surface of the ridge portion of the tight frame 12.

[0036] The folded plate 71a is formed by arranging a plurality of folded plate members having a substantially V-shaped cross-section with a horizontal bottom such that the cross-sections are arranged in the span direction of the steel frame beam 5, and the opposing ends of adjacent folded plate members are attached to the clamping metal fitting 61a.

[0037] The heat insulating material 72 is provided on the upper surface of the folded plate 71a. Although glass wool is used as the heat insulating material 72, it is not limited thereto.

[0038] The heat insulating metal fitting 73 is a fixing member fixed to the top surface of the ridge portion of the folded plate 71a, and fixes the folded plates 71a and 71b to each other. The heat insulating metal fitting 73 is provided via the folded plate 71a on the clamping metal fitting 61a on the top surface of the ridge portion of the tight frame 12. A clamping metal fitting 61b of the same type as the clamping metal fitting 61a is attached to the upper surface of the heat insulating metal fitting 73.

[0039] The folded plate 71b is arranged on the heat insulating material 72. The folded plate roof 7 of the present embodiment has a double-folded plate structure in which the heat insulating material 72 is sandwiched between the upper and lower folded plates 71a and 71b. The folded plate 71b is a corrugated steel plate having a plurality of valleys and ridges, and is formed by arranging a plurality of folded plate members having a substantially V-shaped cross-section with a horizontal bottom such that the cross-sections are arranged in the span direction of the steel frame beam 5. The opposing ends of adjacent folded plate members are attached to the clamping metal fitting 61b on the upper surface of the heat insulating metal fitting 73.

[0040] The connecting fitting 74 is fixed to the top surface of the peak portion of the corrugated plate 71b and is provided on the tightening fitting 61b on the upper surface of the heat insulating fitting 73. The connecting fitting 75 is a beam-shaped member that supports the field board 76, and is arranged so as to extend along the span direction of the steel frame beam 5. The connecting fitting 75 is arranged by being attached to a plurality of connecting fittings 74 arranged in the span direction of the steel frame beam 5.

[0041] The field board 76 is a plate material attached on the connecting fitting 75, and is arranged at an interval upward from the corrugated plate 71b. For the field board 76, a hard wood wool cement board or the like is used, but it is not limited thereto.

[0042] The waterproof material (moisture-proof material) 77 is a sheet-shaped member provided on the field board 76. In this embodiment, the waterproof material 77 is an asphalt roofing, but it is also possible to use a waterproof material other than the asphalt roofing.

[0043] The cushioning material 78 is provided on the waterproof material 77. For the cushioning material 78, a resin material such as polyethylene foam is used, but it is not limited thereto.

[0044] The roof board 79 is a steel plate arranged on the cushioning material 78, and constitutes the upper surface of the corrugated roof 7. In this embodiment, a stainless steel plate having waterproof properties is used as the roof board 79, but it is not limited thereto, and other members can also be used as the roof board.

[0045] In this embodiment, a plate-shaped ceiling material 91 is suspended and supported downward from the corrugated roof 7. More specifically, the lower end portion of a suspension bolt 94 suspended downward from the corrugated roof 7 is attached to a hat steel 93 which is a ceiling base metal member that supports the ceiling material 91. Further, a heat insulating material 92 is arranged on the upper surface of the ceiling material 91. The ceiling material 91 of this embodiment is a sound absorbing board such as a glass wool board, and glass wool or the like is used as the heat insulating material 92, but the ceiling material 91 and the heat insulating material 92 are not limited thereto.

[0046] (3-1. Countermeasures against the uplifting of the folded-plate roof 7) In this embodiment, as a countermeasure against the uplifting of the folded-plate roof 7, a temporary folded-plate member 70 is used. That is, the temporary folded-plate member 70 is provided so as to be continuous forward from the folded plate 71a of the folded-plate roof 7, and the folded-plate member 70 is fixed to the tight frame 12 provided on the roof steel frame 10 (steel beam 5) of the remaining section 7-2 with screws 710.

[0047] Thereby, it is possible to resist the uplifting force of the folded-plate roof 7 generated in the semi-roof state and prevent the breakage from the end of the folded-plate roof 7. The temporary folded-plate member 70 extends in a gable shape toward the remaining section 7-2 (the unconstructed section of the folded-plate roof 7) side, and is also effective as a countermeasure against water immersion described later. The rear end of the folded-plate member 70 is attached to the fastening fitting 61a located at the tip of the remaining section 7-2 side of the partial section 7-1. The front end of the folded-plate member constituting the folded plate 71a is also attached to the fastening fitting 61a.

[0048] In this embodiment, furthermore, as an end treatment of the constructed folded-plate roof 7 in the partial section 7-1, the folded-plate roof 7 is connected and fixed for the purpose of preventing uplift.

[0049] That is, the front end (corresponding to the left side in FIG. 6) of the folded-plate roof 7 in the partial section 7-1 and the roof structure 100 of the remaining section 7-2 are connected by a connecting member 20. The connecting member 20 is a linear member, and a chain is used in this embodiment, but it is not limited thereto. For example, a wire or the like may be used. Hooks 210 and 220 are provided at both ends of the connecting member 20.

[0050] At the front end of the folded-plate roof 7, in order to attach one end of the connecting member 20, a mounting fitting 73' is fixed to the top surface of the peak of the folded plate 71b. The mounting fitting 73' is a member of the same type as the heat insulation fitting (fixing member) 73, and is provided on the heat insulation fitting 73 via the folded plate 71b. The mounting fitting 73' is located on the folded plate 71b, and one end of the connecting member 20 is attached to the mounting fitting 73' using the hook 210.

[0051] In the middle of the connecting member 20, as shown by the arrow a, it is turned back toward the folded plate roof 7 through the ridge portion of the tight frame 12 in the remaining section 7-2. Then, the other end of the connecting member 20 is wound around the mounting fitting 73' as shown by the arrow b and attached to the middle of the connecting member 20 by the hook 220.

[0052] In this way, by connecting the mounting fitting 73' of the folded plate roof 7 in the partial section 7-1 and the roof structure 100 (the tight frame 12 in this embodiment) in the remaining section 7-2 with the connecting member 20, it is possible to resist the uplift of the folded plate roof 7 due to strong winds or the like, and even if the folded plate member 70 at the end of the folded plate roof 7 breaks, it is possible to prevent the collapse of the folded plate roof 7.

[0053] As a result of intensive studies, the inventor has found that the heat insulation fitting 73 at the front end of the folded plate roof 7 and the fastening fitting 61a below it are likely to break against the uplift force. By mounting the mounting fitting 73' as described above and connecting with the connecting member 20, it is possible to prevent the scattering even if the heat insulation fitting 73 and the fastening fitting 61a below it break.

[0054] (3-2. Flooding countermeasures) Also, in this embodiment, as a flooding countermeasure during rainfall or the like, a cover material 30a for preventing flooding between the upper and lower folded plates 71a and 71b and a cover material 30b for preventing flooding between the folded plate roof 7 (folded plate 71a) and the ceiling material 91 are provided at the front end of the folded plate roof 7. Steel plates or the like can be used for the cover materials 30a and 30b.

[0055] The cover material 30a is continuously provided along the flow direction of the folded plates 71a and 71b so as to cover the front ends of the folded plates 71a and 71b of the folded plate roof 7. The flow direction of the folded plates 71a and 71b corresponds to the normal direction of the paper surface in FIG. 6. In this embodiment, the cover material 30a is arranged so as to cover the heat insulation fitting 73 located at the tip on the remaining section 7-2 side of the folded plates 71a and 71b and the connecting fitting 74 above it.

[0056] The cover material 30b is arranged to extend downward from the folded plate roof 7 (folded plate 71a) at the front end of the folded plate roof 7, and its lower end is attached to the hat steel 93 at the front end of the ceiling material 91. Similar to the above-mentioned cover material 30a, the cover material 30b is provided along the flow direction of the folded plates 71a and 71b.

[0057] Also, in order to prevent water from entering between the waterproof material 77 and the field board 76, the front end 771 of the waterproof material 77 is extended forward from the field board 76, and the end 771 is vertically lowered toward the folded plate 71b side and abutted against the upper surface of the folded plate 71b. The end 771 is arranged continuously in the flow direction of the folded plates 71a and 71b.

[0058] (3-3. Countermeasures against scattering of the roof plate 79) Furthermore, in this embodiment, as a countermeasure against scattering of the roof plate 79, a pressing member 40 for pressing the roof plate 79 from above is installed.

[0059] The pressing member 40 is a metal member, and a beam-shaped main body 410 extending in the span direction of the steel frame beam 5 is fixed to the field board 76 and the roof plate 79 by a mounting portion 421 at the front end and a mounting portion 422 at the rear end, respectively. When the main body 410 is fixed by the mounting portions 421 and 422, the front end of the roof plate 79 is pressed against the field board 76 side by a pressing portion 430 provided between the mounting portions 421 and 422 of the main body 410.

[0060] The main body 410 and the mounting portions 421 and 422 are provided corresponding to each steel frame beam 5. However, it is also possible to provide the main body 410 and the mounting portions 421 and 422 at positions other than directly above the steel frame beam 5. The pressing portion 430 is arranged to extend in the direction orthogonal to the span of the steel frame beam 5 and is attached to a plurality of main bodies 410 arranged in the direction orthogonal to the span of the steel frame beam 5. The direction orthogonal to the span of the steel frame beam 5 is a direction orthogonal to the span direction of the steel frame beam 5 in a plan view and corresponds to the flow direction of the folded plates 71a and 71b.

[0061] The pressing member 40 can prevent the roof board 79 from scattering and also prevent water from entering between the field board 76 and the roof board 79. That is, the cross-section of the pressing portion 430 has a hat shape with a pair of front and rear legs 431 and 432. In addition to pressing the roof board 79 from above with the rear leg 432, the front leg 431 closes the front of the roof board 79, thereby reliably preventing the intrusion of rainwater and the like.

[0062] As described above, in this embodiment, in the semi-roof state where only the folded-plate roof 7 in the partial section 7-1 is constructed, a temporary folded-plate member 70 is provided so as to be continuous from the folded plate 71a in the partial section 7-1 to the remaining section 7-2 side, and this is attached to the tight frame 12 provided on the roof steel frame 10. Thereby, it is possible to resist the uplifting force of the folded-plate roof 7 generated in the semi-roof state and prevent the folded-plate roof 7 from breaking from its end. Further, the temporary folded-plate member 70 is also effective as a water intrusion countermeasure by extending in a roof shape toward the remaining section 7-2 (the unconstructed section of the folded-plate roof 7).

[0063] Also, in this embodiment, the mounting bracket 73' provided on the folded-plate roof 7 in the partial section 7-1 and the roof structure 100 in the remaining section (the unconstructed section of the folded-plate roof 7) 7-2 are connected using a linear connecting member 20. Thereby, it is possible to resist the uplifting force of the folded-plate roof 7 generated in the semi-roof state, and even if breakage occurs from the end of the folded-plate roof 7, it is possible to prevent the collapse of the folded-plate roof 7 and the like.

[0064] Also, by using a wire such as a chain as the connecting member 20, it is possible to easily attach the mounting bracket 73' and the roof structure 100 in the remaining section 7-2. Regarding the latter, it is preferable because the attachment to the remaining section 7-2 side can be easily completed by simply passing the linear connecting member 20 through the ridge portion of the tight frame 12. The mounting bracket 73' is provided on the heat insulation bracket 73 via the folded plate 71b, so that even if breakage occurs in the heat insulation bracket 73 or the like due to the uplifting of the folded-plate roof 7, its scattering can be prevented.

[0065] Also, in the present embodiment, the cover material 30a can prevent water from entering between the upper and lower folded plate roofs 71a and 71b in the folded plate roof 7 having a double folded plate structure. Further, the cover material 30b can prevent water from entering between the folded plate roof 7 and the ceiling material 91 suspended and supported from the folded plate roof 7. Also, in the present embodiment, water ingress between the waterproof material 77 and the field board 76 can be prevented by a simple method of extending the waterproof material 77.

[0066] Also, in the present embodiment, the pressing material 40 can press the roof plate 79 from above to prevent it from scattering due to strong winds or the like.

[0067] However, the present invention is not limited to the above-described embodiments. For example, in the present embodiment, the steel frame beam 4 is used as the beam in the short side direction of the arena structure 1, and the steel frame beam 5 is used as the beam in the long side direction of the arena structure 1. Conversely, the steel frame beam 4 may be used as the beam in the long side direction, and the steel frame beam 5 may be used as the beam in the short side direction.

[0068] The plane of the arena structure 1 is not particularly limited, and it may be a circle (a perfect circle) or a polygon such as a rectangle. In any case, the steel frame beams 4 and 5 are arranged in two directions intersecting in the plane. Also, in the present embodiment, the steel frame beams 4 and 5 are used as truss beams, but the structure of the steel frame beams 4 and 5 is not particularly limited. The positions of the vents 8 and the like can also be determined variously according to the arrangement of the steel frame beam 4 and the like.

[0069] Also, in the present embodiment, the connecting member 20 connects the mounting bracket 73' of the folded plate roof 7 in the partial section 7-1 and the tight frame 12 in the remaining section 7-2. However, the connection target on the remaining section 7-2 side is not particularly limited as long as it is the roof structure 100 in the remaining section 7-2, and it may be connected to, for example, the steel frame beam 5. Also, in the present embodiment, the temporary folded plate member 70 is attached to the tight frame 12 in the remaining section 7-2 by screws 710, but attachment may be performed using members other than the screws 710. However, by using the screws 710, the attachment of the folded plate member 70 can be performed simply and reliably.

[0070] In addition, although the folded-plate roof 7 of the present embodiment has a double-folded-plate structure, the configuration of the folded-plate roof 7 is not limited to this. For example, the folded plates of the folded-plate roof 7 may be three or more layers, or may be only one layer. In the latter case, the cover material 30a (see FIG. 6) is omitted. Also, when the wetting of the ceiling material 91 does not pose a problem, it is also possible to omit the cover material 30b.

[0071] In addition, although the present embodiment has been described by taking the construction of the folded-plate roof 7 of the arena structure 1 as an example, the present invention is not limited to the arena structure 1, and can be applied when constructing the folded-plate roofs 7 of various structures such as large-scale logistics facilities, stadiums, gymnasiums, exhibition halls, airports, etc.

[0072] In addition, in the present embodiment, the jack-down of the roof steel frame 10 and the construction of the folded-plate roof 7 were carried out in two steps, but it is also possible to carry out the jack-down of the roof steel frame 10 and the construction of the folded-plate roof 7 in three or more steps in the same procedure. Also, the present invention is not limited to the case of carrying out the jack-down of the roof steel frame 10 and the construction of the folded-plate roof 7, and can be applied to various construction methods in which a semi-roof state occurs during the construction of the folded-plate roof 7.

[0073] As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that those skilled in the art can conceive of various modification examples or correction examples within the scope of the technical idea disclosed in the present application, and it is naturally understood that they also belong to the technical scope of the present invention.
