本発明は、急勾配金属屋根の施工に適した安全性の高い
屋根の施工方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a highly safe roof construction method suitable for constructing a steeply sloped metal roof.
従来、急勾配金属屋根は、鉄骨建て方が完了した後、屋
根勾配に対応した勾配の外部仮設足場を組み、この外部
仮設足場からの作業によって、梁鉄骨への下地貼り、下

った手順で施工されていた。Conventionally, for steep-slope metal roofs, after the steel frame construction is completed, external temporary scaffolding with a slope corresponding to the roof slope is erected, and work from this external temporary scaffolding is used to attach the base to the steel beams and apply a waterproof sheet to the base. Construction was carried out using a procedure that included pasting and finishing metal pasting.
このため、工期が長くかかるばかりでなく、施工中にお
けるどの作業をとっても、材料、工具、作業員の落下の
恐れを伴う危険作業が強いられてきた。For this reason, not only does construction take a long time, but any work performed during construction is dangerous, with the risk of falling materials, tools, and workers.
このような工期、安全面での問題を解決するために、本
発明者らは、下地と仕上げ金属を複合化した防水性の高

足場からの作業によって梁鉄骨に取り付けるようにした
屋根の施工方法を既に開発している。In order to solve these problems in terms of construction time and safety, the present inventors assembled highly waterproof roof panels made of a composite base and finishing metal at a factory, and then used cranes etc. to assemble these roof panels. We have already developed a method for constructing roofs that are attached to steel beams by working from internal temporary scaffolding that is lifted and placed inside the building.
しかしながら、上記の屋根の施工方法では、鉄骨建て方

があるので、内部仮設足場を組み立てるのに必要な時間
だけ屋根パネルの取付けが遅れることになり、安全面で
も工期面でも改良の余地があった。However, in the above roof construction method, after the steel frame construction was completed, internal temporary scaffolding was erected between the steel frames, so the internal temporary scaffolding could not be used to ensure the safety of the steel frame construction. Since there is a process for assembling internal temporary scaffolding between the roof panel installation process and the roof panel installation process, the installation of the roof panel will be delayed by the time required to assemble the internal temporary scaffolding, which will cause a delay in terms of both safety and construction time. There was room for improvement.
本発明は、これらの点を改良し、鉄骨建て方の時点で簡
便な作業足場(こう鋲足場)が得られ、且つ、鉄骨建て
方後、直ちに、屋根パネルの取付は工程に移行できるよ
うにした屋根の施工方法を提供するものである。The present invention improves these points, and makes it possible to obtain a simple work scaffold (tack scaffolding) at the time of steel frame erection, and to be able to move on to the roof panel installation process immediately after the steel frame is erected. The present invention provides a method for constructing a roof with

けるようにしたことを特徴としている。The technical means taken by the present invention to achieve the above object are as follows. That is, in the roof construction method according to the present invention, brackets for attaching roof panels and internal temporary scaffolding are attached to the steel beams on the ground in advance, and the steel beams are hoisted by a crane or the like to construct the steel frame. and
Thereafter, the roof panel lifted by a crane or the like is attached to the bracket by work from the internal temporary scaffolding.

い。That is, on the ground, on the beam steel frame, there is a bracket for mounting the roof panel, an upper part of multiple pairs of hanging brackets for suspending and supporting the permanent catwalk installed in the ceiling, and a structure installed between the upper parts. The steel beams are then lifted with a crane, etc. to construct the steel frame.Then, the lower part of the permanent catwalk and the lifting fittings are lifted with a crane, etc., and the lower part of the The roof panel may be connected to the upper part by working from the internal temporary scaffolding, and the roof panel lifted by a crane or the like may be attached to the bracket by working from the internal temporary scaffolding, or the roof panel may be attached to the beam steel frame on the ground. , a roof panel mounting bracket, a permanent catwalk installed in the ceiling, multiple pairs of hanging fittings for suspending and supporting the permanent catwalk, and an upper part of the hanging fittings. An internal temporary scaffold is attached, and the beam steel frame is hoisted by a crane or the like to construct the steel frame, and then the roof panel lifted by the crane or the like is attached to the bracket by work from the internal temporary scaffold. This is desirable.

作業に移行できる。According to the above configuration, since the internal temporary scaffolding is attached to the steel beam in advance, the internal temporary scaffolding is completed by lifting this beam steel frame with a crane etc. and performing the steel frame erection. After that, you can immediately begin installing the roof panels.
また、クレーン等で吊り上げた屋根パネルを内部仮設足
場からの作業によって梁鉄骨のブラケットに取り付ける
ので、外部仮設足場が不要であり、急勾配の屋根を施工
する場合であっても、材料、工具、作業員の落下の危険
が低減される。In addition, since the roof panels lifted by a crane or the like are attached to the beam steel brackets using internal temporary scaffolding, there is no need for external temporary scaffolding, and even when constructing a steeply sloped roof, materials, tools, etc. The risk of falling for workers is reduced.
以下、本発明の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below based on the drawings.

付けるのである。After the construction of the roof panel 6 is completed and the internal temporary scaffolding 4 is removed, scaffolding for ceiling finishing work (not shown) is installed on the floor inside the building, and work on the scaffolding and permanent catwalk 5 is carried out. As shown in FIG. 4, a horizontal beam 16 serving as a base for ceiling hanging bolts is installed between the lower ends of the hanging fittings 9 of the adjacent permanent catwalks 5, and a hanging hole 7 is installed on the horizontal beam 16. Then, the ceiling base 18 and ceiling equipment 19 such as air conditioning ducts are attached, and the ceiling board 7 is attached to the ceiling base 18.

も可能である。The building shown is a large-span lecture hall, and the roof is a gable roof of uniform height, but the ceiling is designed with consideration to the acoustics in the room. For this reason, the height of the ceiling board 7 increases from one gable side to the other gable side, and the height of the catwalk 5 and the length of the hanging fittings 9 also correspond to this. Therefore, in areas where the length of the hanging bracket 9 is short, there is no problem in attaching up to the permanent catwalk 5 to the beam steel frame, but in areas where the height of the ceiling board 7 is low,
The length of the hanging bracket 9 is long, and in order to attach it to the steel beam first, a tall frame is required to place the steel beam on the ground, making various operations on the ground complicated. Therefore, in this embodiment, as described above, only the upper part 9a of the hanging fittings 9 necessary for constructing the internal temporary scaffolding 4 is attached first, and the lower part 9b and the permanent catwalk 5 are attached.
is separately lifted by a crane or the like and connected to the upper portion 9a. The main cat walk 5 and the lower part 9b of the hanging fitting 9 are lifted up and the upper part 9 is lifted up.
It is also possible to perform the work of connecting to a after the construction of the roof panel 6.

因にならず、室内の音響効果を損なうことがない。According to the above configuration, since the hanging bolts 17 are attached to the horizontal beams 16 installed between the lower ends of the hanging fittings 9 of the permanent catwalk 5, there is a large space between the roof surface and the ceiling plate 7. Despite having a double ceiling structure with without damaging it.

高さが均一な場合に特に有効である。FIG. 5 shows another embodiment of the invention. In this embodiment, on the ground, a bracket 8 for attaching a roof panel, a permanent catwalk 5 to be installed in the ceiling, and a structure for suspending and supporting the permanent catwalk 5 are attached to the beam steel frames 3a and 3b in advance. A plurality of pairs of hanging fittings 9 and an internal temporary scaffolding 4 constructed between the upper parts of the hanging fittings 9 are attached, and the beam steel frames 3a and 3b are lifted with a crane or the like to construct the steel frame. The roof panel 6 is then lifted up by a crane or the like and attached to the bracket 8 by work from the internal temporary scaffolding 4. The other configurations are the same as in the previous embodiment. This embodiment is particularly effective when the distance between the roof and the ceiling is relatively narrow and the ceiling height is uniform.
本発明は、上述した構成よりなるから、次の効果を奏し
得るのである。Since the present invention has the above-described configuration, it can achieve the following effects.
