Description

TECHNICAL FIELD The present invention relates to a roof structure and a construction method thereof, and more particularly, to stably install folded roof shingles irrespective of the thickness of noncombustible heat insulating material, and to locally apply an excessive load to the noncombustible heat insulating material. The present invention relates to a roof structure excellent in workability that can be firmly fixed without any obstacles, and a method for constructing the same.

Folded shingles are sometimes used for roof structures such as warehouses and factories. Various roof structures with folded roof boards have been proposed (see Patent Documents 1 and 2, for example). Since the roof structure is required to be noncombustible and heat insulating, a noncombustible heat insulating material is generally installed under the folded roof shingles.

In the roof structure proposed in Patent Literature 1, a folded roof board (upper roofing material 7) is supported by a fixing member 10 that is fixed to the underlaying material 1 and erected. A heat insulating material 6 is placed on the underlaying material 1, and a fixing member 10 vertically penetrates the heat insulating material 6 (FIG. 1). A structure has also been proposed in which the corrugated fixing member 15 and the underlaying material 1 are joined together with a screw 18 penetrating vertically through the heat insulating material 6 to integrate the underlaying material 1, the heat insulating material 6 and the fixing member 15 ( Paragraph 0025, FIG. 2).

In the roof structure proposed in Patent Document 2, a folded roof board 5 is supported by a tight frame 7 erected on a beam 2, and a heat insulating material 3 is bridged over the beam 2 (Figs. 1 and 2). 4, etc.). The heat insulating material 3 is fixed by pressing the urethane foam 3B on the upper surface thereof with a pressing metal fitting 9B (Fig. 4).

In order to ensure sufficient heat insulation and noncombustibility, the thickness of the heat insulating material becomes large, and the space for installing the heat insulating material becomes insufficient. In particular, refrigerated warehouses and freezer warehouses require a high degree of heat insulation in order to maintain the interior at a low temperature, so the thickness of the heat insulating material is large. Therefore, in order to secure the installation space for the heat insulating material, the height of the fixing member 10 and the screw 18 in the roof structure of Patent Document 1 is increased, and the height of the tight frame 7 in the roof structure of Patent Document 2 is increased to stabilize the folded shingle. It will be disadvantageous to set it as

In addition, since the heat insulating material is made of foamed resin or the like, it is more easily deformed than metal. Therefore, an excessive load acts on the connection portion of the heat insulating material with other members (the underlaying material 1 of Patent Document 1, the fixing member 15, the pressing metal fitting 9B of Patent Document 2), and local deformation is likely to occur. In addition, it is difficult to firmly fix the heat insulating material. Therefore, there is room for improvement in stably installing the folded roof plate and firmly fixing the heat insulating material without localized excessive load. Furthermore, there is room for improvement in constructing the roof structure, since work is mainly performed at high places.

According to the present invention, since the folded shingle is supported by the tight frame that is fixed and erected on the noncombustible heat insulation panel, the purpose is to improve the heat insulation performance to ensure sufficient heat insulation and noncombustibility. Therefore, there is no need to prepare a tight frame according to the thickness of the noncombustible insulation. Then, the beam material, the heat insulating spacer, the nonflammable heat insulating panel and the steel material are integrally connected by the connecting body. Therefore, the lower end is fixed to the beam member that serves as a stable foundation, and the tight frame of an appropriate height makes it possible to stably install the folded shingle.

The noncombustible heat insulating material is not used as it is, but a noncombustible heat insulating panel whose entire surface is covered with a thin metal plate is used, so the load acting on the noncombustible heat insulating panel is mainly distributed widely over the thin metal plate. As a result, the noncombustible heat insulating material can be firmly fixed to the beam material without applying a local excessive load. Furthermore, since the noncombustible heat insulating panel has significantly higher rigidity than the noncombustible heat insulating material, it is possible for the worker to work on the noncombustible heat insulating panel. As a result, it becomes easier to smoothly construct a roof structure at a high place, which is advantageous for improving workability.

Hereinafter, the roof structure and construction method thereof according to the present invention will be described based on the embodiments shown in the drawings.

The embodiment of the roof structure 1 exemplified in FIGS. 1-3 includes a folded roof shingle 8 and is applied to a cold storage warehouse where the temperature difference between indoors and outdoors (outside air) is greater than in typical structures. ing. A refrigerated warehouse is a warehouse whose interior is kept at 10°C or less, and includes a frozen warehouse. The roof structure 1 of the present invention is suitable for large-scale structures compared to ordinary houses, and is suitable for not only refrigerated warehouses, but also for constant-temperature warehouses that maintain a constant temperature, various warehouses, factories, etc. Applicable. In the following embodiments, a case where the roof structure 1 is applied to a cold storage warehouse will be described as an example, but even when the roof structure 1 is applied to a non-refrigerating warehouse, substantially the same structure and construction method will be used.

This roof structure 1 is interposed between a plurality of beam members 2 , a noncombustible heat insulating panel 3 , a folded roof plate 8 , a tight frame 7 , the lower surface of the noncombustible heat insulating panel 3 and the upper surface of the beam member 2 . It has a heat insulating spacer 11 , a steel material 6 installed and extending on the upper surface of the noncombustible heat insulating panel 3 , and a connector 9 penetrating vertically through the noncombustible heat insulating panel 3 and the heat insulating spacer 11 . The directions of arrows W, L, and H in the drawing indicate the width direction, the length direction, and the height direction of the roof structure 1 (folded roof plate 8), respectively.

The beam material 2 is, for example, a steel frame material such as H-shaped steel. The beam 2 extends substantially horizontally. The beams 2 are arranged at suitable intervals as illustrated in FIG. 10 according to the size of the roof structure 1 and the like. A hole is formed in the beam member 2 through which the connecting body 9 passes vertically.

The noncombustible heat insulating panel 3 is composed of a noncombustible heat insulating material 4 and a thin metal plate 5 covering substantially the entire surface of the noncombustible heat insulating material 4 . The incombustible heat insulating panel 3 is a rectangular plate-like body in a plan view. It is The incombustible heat insulating material 4 and the thin metal plate 5 have an integral structure in close contact with each other. The size of the noncombustible heat insulating panel 3 is appropriately set, but the dimension in the W direction is, for example, 900 mm to 1000 mm, and the dimension in the L direction is, for example, 2500 mm to 5000 mm.

A known noncombustible heat insulating material can be used for the noncombustible heat insulating material 4, and for example, a foamed resin such as isocyanurate foam or polyurethane foam is used. In order to manufacture the noncombustible heat insulating panel 3, for example, after manufacturing a box-shaped body (hexahedron) with a cavity inside by bending the thin metal plate 5, resin that becomes the material of the noncombustible heat insulating material 4 in the cavity is used. to foam and fill. Alternatively, the noncombustible heat insulating panel 3 can be manufactured by attaching the thin metal plate 5 to the noncombustible heat insulating material 4 formed in advance.

The noncombustible heat insulating material 4 is set to have an appropriate thickness that is neither excessive nor deficient in heat insulation and noncombustibility, and is set to, for example, 50 mm or more and 300 mm or less. If the thickness is less than 50 mm, it becomes difficult to ensure sufficient heat insulation and noncombustibility.

The thin metal plate 5 is made of various steel plates such as a carbon steel plate for general structure, an aluminum plate, an aluminum alloy plate, or the like. The thickness of the thin metal plate 5 is, for example, 0.35 mm or more and 1.0 mm or less, and more preferably 0.5 mm or more and 0.8 mm or less. If the thickness is too small, it will be difficult to ensure sufficient strength, and if it is too large, the weight will increase and this will be a factor in lowering workability.

Through-holes 3a are formed in the non-combustible heat insulating panel 3 (the non-combustible heat-insulating material 4 and the thin metal plate 5) through which the connector 9 extends vertically. In this embodiment, a cylindrical sleeve 10 made of metal is fitted in the through hole 3a. The length of the sleeve 10 is substantially the same as the thickness of the noncombustible heat insulating panel 3.

A required number of incombustible heat insulating panels 3 are arranged side by side with their side faces facing each other. A gap is formed between the opposing side surfaces of the noncombustible heat insulating panels 3 arranged adjacent to each other, and the gap is filled with the foamed heat insulating material 13 . Various known foamed resins can be used for the foamed heat insulating material 13 . In this embodiment, a tape-shaped moisture-proof material 14 is placed on the upper surface of each noncombustible heat insulating panel 3 so as to straddle the gap between the opposing side surfaces of the noncombustible heat insulating panel 3 over the entire length of the roof structure 1 in the width direction (W direction). Various known moisture-proof tapes can be used as the moisture-proof material 14, and for example, an aluminum-based moisture-proof tape is used. The noncombustible heat insulating panel 3 with this specification is preferably installed over the entire area of the roof structure 1, but a noncombustible heat insulating panel with a different specification from this noncombustible heat insulating panel 3 can be used in a part of the area.

The steel material 6 extends in the W direction on the upper surface of the noncombustible heat insulating panel 3 . In this embodiment, the lip channel steel is used as the steel material 6, but other metal channel steel, angle steel, and the like can be used. The steel member 6 is arranged above the beam member 2 . A hole is formed in the steel material 6 through which the connecting body 9 is vertically inserted.

The tight frame 7 is fixed and erected on the steel material 6 and supports the folded roof plate 8 from below. A plurality of tight frames 7 are arranged at appropriate intervals in the longitudinal direction (L direction). In this embodiment, the tight frame 7 is formed in a wavy shape similar to (similar to) the folded roof plate 8 . The tight frame 7 is formed, for example, by bending a strip-shaped metal plate into a wavy shape. The corrugated bottom of the tight frame 7 is fixed to the upper surface of the steel material 6 by welding or the like.

A corrugated folded roof plate 8 arranged above the noncombustible heat insulating panel 3 is arranged so as to cover the upper surface of the tight frame 7 . The corrugated crests of the folded roof plate 8 and the tight frame 7 are connected by bolts 8a. It is also possible to integrally fix the end portions of the folded roof sheets 8 and the wavy top portion of the tight frame 7 by connecting them together at the wavy top portions.

The upper and lower surfaces of the heat insulating spacer 11 are in contact with the lower surface of the incombustible heat insulating panel 3 and the upper surface of the beam member 2, respectively. The heat insulating spacer 11 is a block-shaped body, and is made of a non-metal such as a hard resin having a lower heat conductivity than metal in order to suppress heat conduction between the nonflammable heat insulating panel 3 and the beam member 2. there is Foamed resin containing air bubbles or solid resin containing no air bubbles can be used as the heat insulating spacer 11 . A through hole 11 a is formed in the heat insulating spacer 11 through which the connecting body 9 passes vertically.

The upper and lower surfaces of the insulating spacer 11 are not parallel to each other, and when the lower surface of the insulating spacer 11 is placed on the horizontal upper surface of the beam 2, the upper surface of the insulating spacer 11 is inclined with respect to the horizontal direction L. . That is, the upper surface of the heat insulating spacer 11 is an inclined surface that is inclined from one end side to the other end side in the L direction. The minimum thickness of the heat insulating spacer 11 is, for example, 20 mm or more, more preferably 30 mm or more. The upper limit of the thickness of the heat insulating spacer 11 is, for example, 100 mm.

Since the noncombustible heat insulating panel 3 is placed on the upper surface (inclined surface) of the heat insulating spacer 11, the upper structure (noncombustible heat insulating panel 3, steel material 6, tight frame 7 and folded roof plate 8) above the heat insulating spacer 11 structure) is inclined from one end side to the other end side in the longitudinal direction (L direction) along the upper surface (inclined surface) of the heat insulating spacer 11 . The connector 9 (body portion 9a) extends vertically.

The connecting body 9 has a rod-like body portion 9a and a nut portion 9b. Threads are formed on the upper end and the lower end of the body portion 9a, and the respective nut portions 9b are screwed together. The body portion 9a is preferably made of a metal having a lower thermal conductivity than the beam member 2 and the steel member 6, and is made of stainless steel, for example.

The upper end portion and the lower end portion of the connecting body 9 are fixed to the steel material 6 and the beam material 2, respectively. More specifically, the main body 9a vertically penetrates the beam 2, the heat insulating spacer 11, the noncombustible heat insulating panel 3, and the steel material 6. 2, and the upper end portion is fixed to the steel material 6 and the nonflammable heat insulating panel 3 by screwing the nut portion 9b. The noncombustible heat insulating panel 3 is vertically sandwiched between the beam material 2 (and the heat insulating spacer 11) and the steel material 6, and the connecting body 9 connects the beam material 2, the heat insulating spacer 11, the noncombustible heat insulating panel 3 and the steel material 6 together. are connected.

In this embodiment, the entire protruding portion of the connecting body 9 (body portion 9 a ) protruding upward from the upper surface of the incombustible heat insulating panel 3 is covered with the heat insulating cover 12 . The heat insulating cover 12 can be made of various known foamed resins, for example. A heat-insulating cover 12 may be provided to cover the entire protruding portion protruding downward from the upper surface of the beam 2 of the connecting body 9 (body portion 9a).

Next, an example of the procedure for constructing the roof structure 1 of the present invention will be described.

First, as illustrated in FIGS. 4 and 5, a heat insulating spacer 11 is placed on the upper surface of the beam member 2 . In order for rainwater to flow smoothly in the longitudinal direction (L direction) on the folded roof plate 8, the upper surface of the heat insulating spacer 11 is inclined at an inclination angle d of about 1.71° to 5.71° with respect to the horizontal. It is better to face it. The heat insulating spacer 11 is positioned so that the through hole 11a formed in the heat insulating spacer 11 and the hole vertically penetrating the upper surface of the beam member 2 are aligned with each other.

In this embodiment, the nut portion 9b is fixed in advance at the position of the hole vertically penetrating the upper surface of the beam member 2 . Before the beam 2 is assembled into the roof structure 1, the nut portion 9b is fixed to the beam 2 by welding or the like at a factory or the like. Note that the nut portion 9b does not have to be fixed to the beam member 2 in advance.

Next, as illustrated in FIGS. 6 and 7, the incombustible heat insulating panel 3 is arranged on the upper surface of the heat insulating spacer 11. As shown in FIG. A sleeve 10 is previously fitted in the through hole 3a formed in the nonflammable heat insulating panel 3. As shown in FIG. At this time, the incombustible heat insulating panel 3 is positioned so that the through hole 3a and the through hole 11a formed in the heat insulating spacer 11 are aligned with each other. A gap is formed between the opposing side surfaces of the noncombustible heat insulating panels 3 arranged adjacent to each other. Incidentally, the sleeve 10 can be optionally provided as required.

Next, as exemplified in FIGS. 8 and 9, the body portion 9a of the connecting body 9 is inserted into the through hole 3a (sleeve 10) and the through hole 11a, and the noncombustible heat insulating panel 3, the heat insulating spacer 11 and the beam 2 are assembled. The main body portion 9a is vertically penetrated through the upper surface. A nut portion 9b is screwed to the lower end of the main body portion 9a and fixed to the beam member 2, and a nut portion 9b is screwed to the upper end portion of the main body portion 9a and fixed to the upper surface of the nonflammable heat insulating panel 3. If the nut portion 9b is not previously fixed to the beam 2, the lower end portion of the body portion 9a of the connecting body 9 inserted through the through hole 3a (sleeve 10) and the through hole 11a is formed on the upper surface of the beam 2. pierce through the hole and protrude downward. A nut portion 9b is screwed to the lower end portion of the body portion 9a that penetrates the upper surface of the beam member 2, and this lower end portion is fixed to the beam member 2. As shown in FIG.

A foamed heat insulating material 13 is filled in the gap between the opposing side surfaces of the noncombustible heat insulating panels 3 arranged adjacent to each other. The foamed heat insulating material 13 can be filled in the gap by spraying, or the foamed heat insulating material 13 can be stuffed and filled. A moisture-proof material 14 is attached to the upper surface of each noncombustible heat insulating panel 3 so as to straddle this gap over the entire length. The moisture-proof material 14 prevents moisture from entering the room from between the opposing side surfaces of the incombustible heat insulating panel 3 .

By performing the above steps, as illustrated in FIG. 10 , the required number of noncombustible heat insulating panels 3 are installed across a plurality of beams 2 . Each noncombustible heat insulating panel 3 is firmly fixed to the beam 2 by a connecting body 9 .

At the connecting portion between the beams 2 and the beams 2, there is a joint that connects the two. A bolt that penetrates vertically protrudes from this joint. Therefore, if the heat insulating spacer 11 is not provided, the bolt may protrude above the lower surface of the noncombustible heat insulating panel 3 and interfere with the noncombustible heat insulating panel 3 . In this embodiment, the insulating spacer 11 positions the lower surface of the noncombustible insulating panel 3 above the upper surface of the beam 2 to some extent, so the insulating spacer 11 also has a function of avoiding interference with the bolt. there is

Next, as illustrated in FIGS. 11 and 12 , the steel material 6 is arranged on the upper surface of the noncombustible heat insulating panel 3 . At this time, the portion of the main body 9a that protrudes from the upper surface of the incombustible heat insulating panel 3 is covered with the heat insulating cover 12, and the uppermost end of the main body 9a is inserted through the hole that penetrates the steel material 6 vertically. Then, the nut portion 9b is screwed onto the uppermost end portion of the body portion 9a, and this uppermost end portion is fixed to the steel material 6. As shown in FIG.

Next, as illustrated in FIGS. 13 and 14, the portion of the main body 9a protruding from the upper surface of the steel material 6 is covered with a heat insulating cover 12. Next, as shown in FIGS. As a result, the entire portion of the noncombustible heat insulating panel 3 protruding from the upper surface is covered with the heat insulating cover 12 .

Next, as illustrated in FIGS. 15 and 16 , a tight frame 7 is erected on the upper surface of the steel material 6 . Next, as illustrated in FIGS. 1 to 3, a folded roof panel 8 is arranged so as to cover the tight frame 7 . Then, the corrugated bottom portion of the tight frame 7 is fixed to the upper surface of the steel material 6 by welding or the like, and the folded roof shingles 8 are laid out on the tight frame 7 . Further, the tight frame 7 and the corrugated tops of the folded roof plate 8 are connected by means of bolts 8a, seaming or engagement.

By performing the above steps, the roof structure 1 illustrated in FIGS. 1 to 3 is constructed. According to this roof structure 1 , the folded roof plate 8 is supported by the tight frame 7 fixed and erected on the noncombustible heat insulating panel 3 . Therefore, even if the noncombustible heat insulating material 4 is thickened to ensure sufficient heat insulation and noncombustibility, it is not necessary to change the height of the tight frame 7 according to the thickness of the noncombustible heat insulating material 4 . Therefore, it is not necessary to prepare a dedicated tight frame 7 for each roof structure 1 that requires different heat insulating properties and noncombustibility.

The beam material 2 , the heat insulating spacer 11 , the nonflammable heat insulating panel 3 and the steel material 6 are integrally connected by the connecting body 9 . In the roof structure 1, the beams 2 serve as a stable foundation, and the tight frame 7 is firmly fixed to the beams 2. - 特許庁Since the folded roof shingles 8 are supported by the tight frame 7 having an appropriate height, it is advantageous for stably installing the folded shingles 8. - 特許庁

As a result, the folded roof panel 8 also reduces the risk of being blown up and detached. In addition, since the folded roof shingles 8 are stably supported by the tight frame 7 , by appropriately setting the strength of the tight frame 7 and the steel material 6 , it is possible to generate solar power on the folded shingle 8 . This is advantageous for stably installing loads such as panels.

Moreover, instead of using the noncombustible heat insulating material 4 as it is, the noncombustible heat insulating panel 3 in which the entire surface of the noncombustible heat insulating material 4 is covered with the thin metal plate 5 is used. Therefore, even if the incombustible heat insulating panel 3 is sandwiched between the beam 2 (and the heat insulating spacer 11) and the steel material 6 and firmly fixed to the beam 2, the load (compressive force) acting on the incombustible heat insulating panel 3 is mainly are widely distributed in the metal sheet 5. As a result, the incombustible heat insulating material 4 can be firmly fixed to the beam member 2 without applying a local excessive load. As a result, local deformation of the noncombustible heat insulating material 4 is prevented, which is advantageous for ensuring sufficient heat insulation and noncombustibility over a long period of time.

The use of the thin metal plate 5 on the surface of the incombustible heat insulating panel 3 is advantageous in preventing the humidity of the outside air from entering the room. In addition, although the plate-like body formed of the thin metal plate 5 does not have strict airtightness, it covers practically the entire surface of the nonflammable heat insulating material 4, so that the surface of the nonflammable heat insulating material 4 is not exhausted. hardly exposed. Therefore, it is advantageous for suppressing deterioration of the noncombustible heat insulating material 4 over time, and it is also advantageous for suppressing leakage of the air contained in the noncombustible heat insulating material 4 to the outside over time.

In this embodiment, the connecting force (compressive force) that integrally connects the beam material 2 , the heat insulating spacer 11 , the nonflammable heat insulating panel 3 and the steel material 6 acts mainly on the sleeve 10 .

A steel material is extended and installed above the noncombustible heat insulating panel that fits, the foam heat insulating material and the heat insulating spacer are vertically penetrated, and the upper end and the lower end of the connecting body are fixed to the steel material and the beam material, respectively. Thus, the beam material, the heat insulating spacer and the steel material are integrally connected, and the folded roof plate is fixed to the tight frame fixed and erected on the steel material. How the structure is built.
