Description

[Technical Field]

[0001] The present invention relates to a joint structure between a folded plate roof and a partition wall and a joint construction method between a folded plate roof and a partition wall. [Background technology]

[0002] As an example of an interface structure between a folded-plate roof with continuous gable portions at predetermined intervals and a partition wall that is installed along the direction in which the gable portions extend while dividing the interior space of the building, there is known an interface structure using door frames, as shown in Patent Document 1. In a conventional interface structure using door frames, a pair of door frames are attached opposite each other to both sides of the upper part of the partition wall, a fire-resistant covering material is sandwiched and held between the pair of door frames, and the pair of door frames are placed in the gap between the gable portions of the folded-plate roof and the partition wall to close the gap.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-3112783 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned conventional joint structure has a problem in terms of workability, as the fire-resistant covering material placed between the pair of panels may fall off during construction.

[0005] In addition, a gap is provided between the panel door and the corrugated roof to take into account the bending of the corrugated roof and movement due to heat, but there is a risk that light from adjacent rooms will leak through this gap.

[0006] Furthermore, the smokeproofing performance of conventional joint structures depends on the degree of filling of the fire-resistant covering material placed between the pair of panels and the gable portion of the corrugated roof, so the smokeproofing performance varies depending on the skill of the contractor.

[0007] Therefore, the present invention has been made with an eye on the problems of the conventional examples, and aims to provide a joint structure between a corrugated roof and a partition wall, and a construction method for jointing a corrugated roof and a partition wall, which can prevent the fire-resistant covering material placed between the corrugated roof and the partition wall from falling off and improve fire resistance and smoke prevention performance while preventing light leakage from other rooms. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, one embodiment of the present invention provides an interface structure between a corrugated roof and a partition wall, which is an interface structure between a corrugated roof having a plurality of continuous gable portions at a predetermined interval and a partition wall that divides the interior space of a building and is installed along the direction in which the plurality of continuous gable portions are arranged, and is equipped with a panel door attached to the top of the partition wall and blocking the gap between the top of the partition wall and the gable portions of the corrugated roof, a block-shaped first fire-resistant covering material fixed integrally to the panel door, and a strip-shaped second fire-resistant covering material arranged on the outer periphery of the panel door and abutting against the underside of the gable portions in a tightly contacting state.

[0009] In addition, one embodiment of the present invention relates to a method of connecting a corrugated roof and a partition wall, which is a method of connecting a corrugated roof having a plurality of continuous gable portions at predetermined intervals with a partition wall that divides the interior space of a building and is installed along the direction in which the plurality of continuous gable portions are arranged, and includes the steps of attaching a panel door to the upper end of the partition wall, which has a first fire-resistant covering material attached as an integral part and a band-shaped second fire-resistant covering material attached to its upper outer periphery, and erecting the partition wall into the interior space of the building so that the panel door pushes up the gable portions from below and the second fire-resistant covering material is in close contact with the underside of the gable portions. [Effects of the Invention]

[0010] According to the joint structure between a corrugated roof and a partition wall and the joint construction method between a corrugated roof and a partition wall of the present invention, it is possible to prevent the fire-resistant covering material placed between the corrugated roof and the partition wall from falling off, and to improve fire resistance and smoke prevention performance while preventing light leakage from other rooms.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Next, an embodiment of the present invention will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the relationship between thickness and planar dimensions, the thickness ratio of each layer, etc., may differ from the actual ones. Therefore, specific thicknesses and dimensions should be determined with reference to the following description. Furthermore, it goes without saying that the drawings may include parts with different dimensional relationships and ratios.

[0013] Furthermore, the embodiments shown below are merely examples of devices and methods for embodying the technical concept of the present invention, and the technical concept of the present invention does not limit the materials, shapes, structures, arrangements, etc. of the components to those described below. The technical concept of the present invention can be modified in various ways within the technical scope defined by the claims.

[0014] In the following description, directional terms such as "top," "bottom," "bottom," "front," and "rear" are used with reference to the directions in the accompanying drawings.

[0015] FIG. 1 is a view showing one embodiment of a joint structure between a folded-plate roof 1 and a partition wall 2, viewed from the front side of the partition wall 2.

[0016] The folded plate roof 1 comprises a first folded plate roof 3, a second folded plate roof 4 arranged above the first folded plate roof 3, and a heat insulating material 5 arranged between the first and second folded plate roofs 3, 4.

[0017] The first folded plate roof 3 has multiple gable portions 3a formed at predetermined intervals in the left-right direction of FIG. 1. The second folded plate roof 4 has the same shape as the gable portions 3a of the first folded plate roof 3, and multiple gable portions 4a having the same shape as the gable portions 3a are formed at predetermined intervals in the left-right direction of FIG. 1. The second folded plate roof 4 is installed so that the gable portions 4a are located above the gable portions 3a of the first folded plate roof 3. A heat insulating material 5 is arranged between the upper surface of the first folded plate roof 3 and the lower surface of the second folded plate roof 4.

[0018] The partition wall 2 is installed along the left-right direction in FIG. 1 where the gable portion 3a (or gable portion 4a) of the folded-plate roof 1 is continuous.

[0019] A gap is formed between the upper end of the partition wall 2 and the gable portion 3a between the corrugated roof 1 and the upper part of the partition wall 2, but this gap is closed by placing a door 6 in it.

[0020] 2 and 3, the panel door 6 is made of a metal member and includes a closing plate 7 having substantially the same shape as the angled portion 3a, an L-shaped mounting plate portion 8 formed integrally with the lower portion of the closing plate 7, and first to third side plates 10, 11, and 12 rising from the edge of the closing plate 7 to form a storage recess 9. The panel door 6 of this embodiment is formed integrally by making cuts in a single metal plate and bending it, but the member forming the closing plate 7 and the first to third side plates 10, 11, and 12 integrally and the mounting plate portion 8 may also be manufactured separately and joined together by riveting or screws.

[0021] As shown in Figure 1, the panel door 6 is attached to the upper end of the partition wall 2 by abutting the horizontal portion 8a of the mounting plate portion 8 against the upper end surface of the partition wall 2 at a position corresponding to the gable portion 3a of the first corrugated roof 3 and fixing the vertical portion 8b of the mounting plate portion 8 to the upper side surface of the partition wall 2 with screws 13.

[0022] As shown in Figure 1, the storage recess 9 of the panel door 6 is a mountain-shaped space that stores a block of rock wool board 14. The rock wool board 14 is a mountain-shaped member that is roughly the same shape as the storage recess 9, and is fixed to the inner wall of the closure plate 7 via a fixing member 15 shown in Figure 4.

[0023] The fixing member 15 includes a base 15a, a fitting recess 15b provided in a part of the base 15a, and a thin-diameter connecting rod 15d provided with a holding head 15c at one end.

[0024] The base 15a is fixed to the inner wall of the closure plate 7 with adhesive, and the other end of the connecting rod 15d is inserted from the outer surface of the rock wool board 14, its tip is fitted into the fitting recess 15b, and the retaining head 15c comes into surface contact with the outer surface of the rock wool board 14, thereby holding the rock wool board 14 in the storage recess 9 of the panel door 6.

[0025] 1, a strip of fire-resistant felt 16 is adhered to the outer periphery of the first to third side panels 10, 11, and 12 of the panel door 6. Here, the panel door 6 attached to the upper end of the partition wall 2 is positioned by pushing up the angled portion 3a of the first folded-plate roof 3 from below, so that the fire-resistant felt 16 is in close contact with the underside of the angled portion 3a of the first folded-plate roof 3.

[0026] The folded-plate roof of the present invention corresponds to the first folded-plate roof 3, the gable portion of the present invention corresponds to the gable portion 3a, the mounting portion of the present invention corresponds to the mounting plate portion 8, the first fire-resistant covering material of the present invention corresponds to the rock wool board 14, the second fire-resistant covering material of the present invention corresponds to the fire-resistant felt 16, and the side panels of the present invention correspond to the first to third side panels 10, 11, and 12.

[0027] Next, a construction method for the joint structure between the folded-plate roof 1 and the partition wall 2 will be described with reference to FIGS. 5(a), 5(b) and 1. FIG.

[0028] As shown in Figure 5(a), a rock wool board 14 is held in the storage recess 9 of the panel door 6 using a fixing member 15, and a strip of fireproof felt 16 is glued and placed around the outer periphery of the panel door 6. Next, the panel door 6 is attached to the upper end of the partition wall 2.

[0029] Next, the partition wall 2 is placed so as to divide the interior space of the building and to follow the direction in which the gable portions 3a, 4a of the folded-plate roof 1 are continuous. At this time, as shown in Figure 5(b), the partition wall 2 is erected so that the door 6 approaches the gable portion 3a of the first folded-plate roof 3 from below. Then, as shown in Figure 1, the door 6 pushes up the gable portion 3a of the first folded-plate roof 3 from below, and the erection of the partition wall 2 is completed when the fireproof felt 16 is in tight contact with the underside of the gable portion 3a.

[0030] According to the construction method of the joint structure between the corrugated roof 1 and the partition wall 2 described above, the rock wool board 14 placed in the storage recess 9 of the panel door 6 is held to the inner wall of the storage recess 9 via the fixing member 15, and there is no risk of it falling off during the joint construction, so the work efficiency of the joint construction can be greatly improved.

[0031] In addition, the fireproof felt 16 arranged on the outer periphery of the panel door 6 (the outer periphery of the first to third side panels 10, 11, 12) is in close contact with the underside of the gable portion 3a of the first corrugated roof 3, so no gap occurs between the panel door 6 and the gable portion 3a, and there is no risk of light leaking into adjacent rooms.

[0032] In addition, by storing a specified volume of rock wool board 14 required for fire resistance and smoke prevention performance in the storage recess 9 of the panel door 6, fire resistance and smoke prevention performance can be improved regardless of the skill of the contractor.

[0033] Next, FIG. 6 is a diagram showing the structure of a second embodiment in which a rock wool board 14 is held in the storage recess 9 of the panel door 6. As shown in FIG.

[0034] The second embodiment does not use the fixing member 15 shown in Fig. 1, and a first retaining piece 17 is formed from a part of the opening side edge of the first side panel 10 of the panel door 6 toward the second side panel 11. Also, a second retaining piece 18 is formed from a part of the opening side edge of the second side panel 11 of the panel door 6 toward the first side panel 10. The rock wool board 14 stored in the storage recess 9 of the panel door 6 is prevented from falling out of the storage recess 9 by engaging with the first retaining piece 17 and the second retaining piece 18.

[0035] In this embodiment, the panel door 6 having the first retaining piece 17 and the second retaining piece 18 is formed by cutting a single metal plate and bending it to form it as a single piece, but the component forming the closure plate 7, the first to third side plates 10, 11, 12, the first retaining piece 17 and the second retaining piece 18 as a single piece and the mounting plate portion 8 may also be manufactured separately and then joined together by riveting or screws.

[0036] Therefore, in this embodiment, the rock wool board 14 placed in the storage recess 9 of the panel door 6 is held in the storage recess 9 by engaging with the first holding piece 17 and the second holding piece 18, and there is no risk of it falling off during the connection work, which greatly improves the work efficiency of the connection work.

[0037] The positions at which the first retaining piece 17 and the second retaining piece 18 are formed are not limited to the positions shown in Figure 6, and may be formed, for example, on the third side plate 12 and the horizontal portion 8a of the mounting plate portion 8, and are not limited to two locations for the first retaining piece 17 and the second retaining piece 18.

[0038] The holding pieces according to the present invention correspond to the first holding piece 17 and the second holding piece 18. [Explanation of symbols]
