[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel roof having a sufficient performance in terms of rain, heat insulation and dew condensation, and surface strength of a roof surface, and capable of coping with future systemization of a roof such as addition of a solar system. Related to the structure.

2. Description of the Related Art Japanese Patent Application No. Hei 2-236618 (Japanese Unexamined Patent Application Publication No. 4-11) discloses a roof made of a fixed-size panel by forming a folded part on the periphery of a roof material.
No. 5048). The present invention has advantages such as excellent roofing material productivity and workability, but also has the following problems.

[0003] In terms of rain performance, the roof material is made into a fixed-size panel, so that it has a gutter-like joint at the upper end. However, accumulation of dust and fallen leaves due to aging occurs in the gutter-like joint. Then, since drainage to the inner gutter laid in the flow direction is not performed smoothly, there is a possibility that water leaks from the upper and lower joints to the indoor side.

In terms of heat insulation and internal dew condensation, when the backup material is a heat insulating material, it exhibits excellent heat insulation properties. However, since a required circulating air layer is not formed inside the backup material, internal dew condensation occurs. May occur.

With respect to the surface strength of the roof surface, it is of course possible to use a backup material having the same thickness as that of the gutter-like joint to form the air layer. That is, since a heat insulating material having a high density and a high heat insulating property has not been put to practical use, a backup material (foamed urethane, foamed foam, (Resin-based materials such as polystyrene and foamed polyethylene, fiber-based materials such as glass wool and rock wool, and the typical value of bulk specific gravity generally recognized as a heat insulating material is about 0.1 to 0.2)
Or a backup material that has high strength and high density but is inferior in heat insulation to the thickness of the roof material (such as a flame-retardant wood wool cement board, a hard wood chip cement board, a fiber-mixed slate board, etc.) If at least one of the above-mentioned configurations is adopted, the surface strength of the roof surface may be insufficient. In addition, the low-density and high-insulation backup material exhibits an appropriate backup effect when an evenly distributed load is applied in a filling method, but since the bulk specific gravity is low, there is space on the back side. When a concentrated load is applied to the central portion, there is a high possibility of falling off due to breakage or the like.

As described above, with respect to the configuration inside the panel roofing material, there are restrictions on the configuration due to the priorities of the performance of rain, heat insulation and dew condensation, and surface strength. Instead, it is difficult to replace with a solar cell panel and to systematize the roof.

In this system, the roof surface rises to 80 ° C. or more due to the solar radiation, but when the solar cells are excessively heated by the solar radiation, the energy conversion efficiency generally tends to decrease. Unless a special modification is made to the indoor side configuration, simply replacing it with a panel roof cannot cope with future roof systemization represented by solar cells.

[0008]

The problem to be solved is that when the panel roofing material is of a fixed size, it is necessary to avoid the occurrence of inferiority in the performance of rain, heat insulation and dew condensation, and roof surface strength. It is not possible to cope with the systematization of the roof such as replacement with solar panels in the future.

[0009]

In order to solve the above-mentioned problems, a panel roofing material having a fold portion formed on a peripheral edge thereof is laid so that a water-side fold portion in the flow direction overlaps a water-fold portion. In the structure of the panel roof consisting of, underlaying a roofing material made of a water-impermeable material in which a plurality of concavo-convex portions forming a space portion on the outdoor side are continuously arranged in parallel in the flow direction on the foundation, at least In the form of straddling the adjacent convex portion of the underlaying roof material, a panel roof holding member is fixed on the convex portion,
A backup material is disposed at a position surrounded by the connection space between the overlapped folded portion and the lateral folded portion of the panel roof material on the panel roof holding member and the projection, and a panel roof material adjacent to the connection space is provided. The folded portion of the panel roof material is held by the panel roof holding member so that the folded portion is positioned.

Further, in the present invention, there is provided a panel roof structure in which a panel roofing material having a folded portion formed on a peripheral edge is laid so that a water-side folded portion in the flow direction overlaps a water-folded lower portion. On the ground, laying a roofing material made of a water-impermeable material having a plurality of concavities and convexities forming a space portion on the outdoor side in parallel in the flow direction, and laying a roofing material, and at least the roofing material adjacent to the roofing material In the form of straddling the projection, the panel roof holding member is fixed on the projection, and the panel roof holding member laterally adjacent to the panel roof is further straddled on the projection, and a cross-section substantially open at the top. Auxiliary gutters and backup material receivers with a U-shaped gutter part and backup material receiving flanges on both sides of the lower part of the gutter part are arranged and fixed at regular intervals in the flow direction, and the connection space of the horizontal folded part of the panel roof material And the auxiliary gutter and backup material receiver A backup material is disposed at a position, and the folded portion of the panel roofing material adjacent to the connection space is located at the overlapped folded portion of the panel roofing material adjacent to the gutter portion. The folded part of the panel roof material in the connection space is held by the holding member.

Further, in the present invention, the panel roof material and the backup material are integrated in advance.

Further, in the present invention, a required number of solar cell panels, each having a folded portion having substantially the same shape as that of the panel roofing material formed on the periphery thereof, are arranged and held in an arbitrary position on the roof surface instead of the panel roofing material. It is characterized by becoming.

Further, in the present invention, the decorative portion covering the connection space of the panel roofing material and the panel roofing material or the engaged portion of the cap holding member fixed to the panel roof holding member or the panel roof holding member are elastically engaged. The connection space of the panel roofing material is made up with a decorative cap having an engaging portion.

The panel roofing material of the present invention is of a fixed size, and its length is an integral multiple of the purlin interval (606, 750, 910 mm) plus an overlap margin, or a size of about 500 to 3000 mm that can be handled alone by a construction worker. is there. Also, the width is 300 to 1000mm
It is about 500mm to 600mm mainly. The plate thickness is usually about 1 mm, and the representative plate thickness of each is about 1.2 mm for a thick wall (however, 1.6 mm above this), and about 0.6 mm for a thin wall.

The base material is a steel or wooden beam, a purlin or RC frame, a structure in which a known plate-like base material such as a wood-based, resin-based, or inorganic fiber-based material is interposed on the above-described base, ALC ,
PC panel and the like.

The roofing material is made of a metal material such as a surface-treated steel plate, a stainless steel plate, an aluminum alloy plate, or a resin material such as polycarbonate or acrylic, or a corrugated cardboard material subjected to a special surface treatment for waterproofing. A resin-insulated material such as urethane foam, polystyrene foam, polyethylene foam, etc. on the inside of the metal material, and a waterproof treatment applied to the surface of the resin-based heat insulator. The underlay roof material forms a drainage space and a ventilation space at least between the concave portion and the backup material by the concave and convex portions on the outdoor side. . For example, the pressing strength may be improved by using a mode in which a reinforcing member is provided in a concave portion on the indoor side. An opening for drainage on the eaves side is formed on the eaves side (e.g., eaves arabesque and eaves drainage part) of the underlaying roofing material, so a ridge side ventilation device such as a ventilation building is installed on the ridge side. It is possible to form a flowing air layer alone. The underlaying roof material is fixed to the foundation by passing a bolt erected on the foundation through a fixing hole in the projection and tightening a nut or simply driving a fixing screw, a nail, or the like into the foundation side.

The panel roof holding member is made of resin or metal, and holding of the panel roof material is not limited to holding means using a pressing member or a screw. It may be a holding means such as a relationship. The fixing of the panel roof holding member to the underlaying roofing material may be performed simultaneously with the fixing of the above-described underlaying roofing material, or may be performed independently with screws or the like. In this case, the panel roof holding member may be fixed by welding.

As a backup material, urethane foam,
Resin-based heat-insulating materials such as expanded polystyrene and expanded polyethylene are effective, and are effective in achieving heat insulation and reducing the weight of the roof structure. Further, another heat insulating member may be used. For example, a wood-based cement board having a low bulk specific gravity and a heat insulation standard can be used. The size of this backup material is similar to the panel roofing material, but has a slightly smaller similar shape.

The auxiliary gutter / backup material receiver is made of resin or metal, and has a continuous shape corresponding to the length of the overlapping folded portion between the upper side and the lower side of the adjacent panel roofing material. The receiving flange is not limited to a continuous shape, and may be an intermittent continuous shape.
In addition, it is preferable to provide a drainage portion hanging down toward the concave portion of the underlaying roof material functioning as a main gutter at the bottom portion at both ends of the gutter portion, and to control the flow of rainwater from the gutter portion functioning as a sub-gutter to the concave portion. It can be done smoothly without delay.

A solar cell panel which can be replaced with a panel roofing material is a battery module having a surface covered with a light-transmitting material such as glass, water-tightly treated around the surface, and a single-crystal, polycrystalline, amorphous, etc. solar cell disposed inside. In this case, a folded portion having substantially the same shape as the panel roofing material is attached to the periphery thereof, or a frame material having substantially the same shape as the panel roofing material is previously formed on the periphery.
The replacement and combination of the solar cell panel and the panel roofing material may be replaced in the future, or may be incorporated at the time of new construction.

The decorative cap is made of a long resin or metal and may be of any suitable form that can make up the connection space between the panel roofs adjacent to each other in the lateral direction, and the form is not particularly limited. By performing a watertight treatment such as waterproof rubber or packing between the back surface of the decorative cap and the surface of the panel roofing material, the rain finish is further improved. The cap holding member for holding the decorative cap is made of a short or long resin or metal.

[0022]

[Function] A roofing material made of a water-impermeable material having a plurality of concavities and convexities forming a space portion on the outdoor side is laid on a base, and the roofing material straddles an adjacent convex portion of the roofing material. Fix the panel roof holding member with the backing material, and place the backup material in a position surrounded by the connection space between the overlapping folds below and above the panel roofing material above and below the panel roof holding material on the panel roof holding member and the projection. It is installed, and the folded part of the adjacent panel roof material in this connection space is held by the panel roof holding member, so that sediment due to aging or concentration occurs in the overlapping folded part on the water side and under the water. Due to unforeseen circumstances such as heavy rain,
Even if water is flooded on the indoor side, it can be drained to the downstream side with a roofing material laid all over the indoor side, and there is no water leakage accident.

[0023] Further, since an air layer is formed on the indoor side of the panel roofing material, which is formed by a space formed by the uneven portions of the underlaying roofing material, internal dew condensation can be prevented. And, since the back surface of the panel roofing material or the backup material is supported by the panel holding member and the convex portion of the roofing material,
The thickness of the panel roofing material can be reduced, and as the backup material, a material having low density and low strength but excellent in heat insulation can be selected and used. As a result, it is possible to provide a roof excellent in heat insulation and strength performance at relatively low cost.

[0024] On the ground, a roofing material made of a water-impermeable material having a plurality of concavities and convexities forming a space portion on the outdoor side is laid, and the roofing material straddles adjacent protrusions of the roofing material. The panel roof holding member is fixed with a, and it is straddled on the panel roof holding member adjacent to the horizontal direction and further over the convex portion, and a gutter portion having a substantially U-shaped cross section opening upward and backup materials on both sides of the lower end of the gutter portion. Auxiliary gutter / backup material receivers with receiving flanges are arranged and fixed at regular intervals in the flow direction, and the backup material is located at a position surrounded by the auxiliary gutter / backup material receiver and the connection space at the lower part of the panel roofing material in the horizontal direction. The panel roof material adjacent to the connection space is positioned such that the folded portion of the panel roof material adjacent to the connection space is adjacent to the gutter portion, and the overlapped folded portion of the panel roof material is positioned adjacent to the gutter portion. Hold the folded part of Even if sedimentation due to aging occurs on the overlapping folded part on the upper and lower sides of the water and flooding on the indoor side occurs due to unforeseen circumstances such as concentrated heavy rain, the auxiliary gutter and backup material can be received. The drainage can be drained to the downstream side by the under-roofing material laid all over the indoor side through the gutter section, thereby preventing a water leakage accident.

[0025] Further, since an air layer is formed on the indoor side of the panel roofing material, which is formed by a space formed by the uneven portions of the underlaying roofing material, internal dew condensation can be prevented. Since the panel roofing material can be supported by the backup material and the auxiliary gutter / backup material receiver, and the backup material can be supported on the entire circumference by the backup material receiving flange and the projection of the panel roof holding member and the underlaying roof material, The thickness of the roof plate can be reduced, and a backup material having low density and low strength but excellent in heat insulation can be selected and used. As a result, since the cost of the main member can be reduced, a roof having excellent heat insulation and strength performance can be provided relatively inexpensively.

Since the panel roofing material and the backup material are integrated and compounded in advance, even with a combination of a thin-walled material and a low-density heat insulating material, the strength performance is further improved, especially with respect to the load acting on the bending, and Even if the backup material is broken, the required space can be continued without dropping into the concave portion, and the workability is improved because it is integral.

Since a required number of solar cell panels, each having a folded portion having substantially the same shape as the panel roofing material formed on the periphery thereof, are arranged and held at an arbitrary position on the roof surface in place of the panel roofing material, a new structure is provided. When installing solar cells, of course, according to the future needs, it is only necessary to replace the panel roof material with solar cell panels, so when adding such a solar cell system, the indoor side of the roof structure There is a great advantage that the structure does not have to be specially modified, and there is no need for troublesome related works such as installation of a stand on the roof. Further, during the replacement work, even if it is rainy during the short period of time when the existing panel roofing material is removed, there is no underground roofing material, so no water leakage accident is caused.

Further, a systemized roof corresponding to solar energy can be obtained by a simple operation of merely replacing required unit panels in the roof surface configuration. And
Since an air layer is formed inside the panel roof,
It is possible to prevent the conversion efficiency of the solar cell from lowering due to an excessive temperature rise. In addition, since the wiring can be placed in the air space, there is no need to perform wiring work involving waterproof treatment on the roof surface.

There is provided a decorative portion for covering the connection space of the panel roofing material, and an engaging portion for elastically engaging the engaged portion of the panel roofing material or the cap holding member fixed to the panel roof holding member or the panel roof holding member. Since the connecting space of the panel roofing material is covered with a decorative cap, the folded portion in the horizontal direction can be easily covered, and the rain finish and the design are improved.

A backup material 29 is laid on the upper and lower surfaces of the backup material 29, and the back surface of the backup material 29 is supported by the convex portion 4 having the same height level and the first and second backup material receiving portions 14, 17.

The backup material 29 is made of a resin-based heat insulating material, and is formed into a similar shape having a size slightly smaller than the panel roof material 30. The backup material 29 is laid over the first and second backup material receiving portions 14 and 17 and the convex portion 4 between the upright portions 18 of the panel roof holding member 9 adjacent to the lateral direction, and is later provided in the flow direction. The overlap between the upper folding part 31 and the lower folding part 33 of the panel roofing material 30 to be described is laid on the first and second backup material receiving parts 14 and 17 and the convex part 4 at intervals.

The panel roofing material 30 is made of a fixed-sized metal plate in which the total length in the flow direction of the roof is divided into a desired number. A substantially U-shaped underwater folding part 31 is formed, and the lower edge of the substantially U-shaped underwater folding part 31 is folded down and then extended horizontally to the underwater to form a substantially L-shaped underwater folding part 33. In addition, left and right folded lower portions 35 and 35 are formed on the left and right side edges in the lateral direction, respectively, after folding the same edge and then turning outward. Note that the water folding part 31 may be substantially L-shaped without the rising part 31a.

【The invention's effect】

A. According to claim 1, underlaying a roofing material made of a water-impermeable material having a plurality of concavities and convexities forming a space portion on the outdoor side is laid on the groundwork, and straddles the adjacent convex portion of the roofing roofing material. The panel roof holding member is fixed in the form of a backing, and it is backed up at a position surrounded by the connection space between the overlapping folds on the upper and lower sides of the panel roofing material on the panel roof holding member and the protrusion, and the folds in the horizontal direction In this connection space, the folded part of the adjacent panel roof material in this connection space is held by the panel roof holding member, so that sediment due to aging may occur in the overlapping folded part on the water side and under the water. However, even if an inundation occurs on the indoor side due to an unexpected situation such as a torrential downpour, the water can be drained to the downstream side by the underlaying roof material laid all over the indoor side, thereby preventing a water leakage accident.

B. According to the said paragraph, since the air layer which consists of a space part by the uneven | corrugated part of an underlaying roofing material is formed in the indoor side of a panel roofing material, internal dew condensation can be prevented. And since the back surface of the panel roofing material or the backup material is supported by the panel holding member and the convex portion of the roofing material, the thickness of the panel roofing material can be reduced, and the backup material also has low density and low strength. However, a material having excellent heat insulating properties can be selected and used. As a result,
A roof excellent in heat insulation and strength performance can be provided relatively inexpensively.

C. According to claim 2, underlaying a roofing material made of a water-impermeable material in which a plurality of uneven portions forming a space portion on the outdoor side are continuous on the ground, and straddling the adjacent convex portion of the roofing roofing material. The panel roof holding member is fixed in such a way that it crosses over the laterally adjacent panel roof holding member and further over the convex portion, and the gutter portion having a substantially U-shaped cross section and the lower end of the gutter portion open at the upper side. Auxiliary gutters and backup material receivers with backup material receiving flanges are arranged at regular intervals in the flow direction.
Fix it, and install the backup material at the position surrounded by the connecting space in the horizontal folding part of the panel roofing material and the auxiliary gutter / backup material receiver.The folding part of the panel roofing material adjacent to the connecting space is Since the overlapping folds of adjacent panel roofing materials are located, and the panel roof holding members hold the folds of panel roofing materials in the connection space, the overlapping folds of the water above and below the water Even if sediment is generated at the bottom due to aging, or due to unforeseen circumstances such as concentrated torrential rain, flooding on the indoor side occurs, it is laid all over the indoor side through the gutter part of the auxiliary gutter and backup material receiver. Drainage can be drained downstream with a roofing material, which does not cause water leakage accidents.

D. According to the said paragraph, since the air layer which consists of a space part by the uneven | corrugated part of an underlaying roofing material is formed in the indoor side of a panel roofing material, internal dew condensation can be prevented. Since the panel roofing material can be supported by the backup material and the auxiliary gutter / backup material receiver, and the backup material can be supported on the entire circumference by the backup material receiving flange and the projection of the panel roof holding member and the underlaying roof material, The thickness of the roof plate can be reduced, and a backup material having low density and low strength but excellent in heat insulation can be selected and used. As a result, since the cost of the main member can be reduced, a roof having excellent heat insulation and strength performance can be provided relatively inexpensively.

E. According to claim 3, since the panel roofing material and the backup material are integrated and compounded in advance, even if a combination of a thin plate material and a low-density heat insulating material is used,
Especially for the load acting in bending, the strength performance is further improved, and even if the backup material is broken, it does not fall into the concave portion and the required space can be continued,
And since it is one, the workability is improved.

F. According to claim 4, a solar cell panel having a folded portion having substantially the same shape as the panel roofing material formed on a periphery thereof,
Because the required number of panels are arranged and maintained in place of the panel roofing material at an arbitrary position on the roof surface, not only at the time of new construction, but also in the case of installing solar cells according to future needs,
Since it is only necessary to replace the panel roofing material with a solar cell panel, there is a great advantage in that the addition of such a solar cell system does not require special renovation of the indoor structure of the roof structure, and also a mounting on the roof. There is no need to do any troublesome related works such as installation. In addition, during the replacement work,
In the short term when the existing panel roofing material is removed, even if it rains, there is no underlaying roofing material, so there will be no water leakage accident.

G. According to the above item, a systemized roof corresponding to solar energy can be obtained by a simple operation of simply replacing required unit panels in the roof surface configuration. Further, since an air layer is formed inside the panel roof, it is possible to prevent the conversion efficiency of the solar cell from being lowered due to an excessive rise in temperature. In addition, since the wiring can be placed in the air space, there is no need to perform wiring work involving waterproof treatment on the roof surface.

H. According to claim 5, the decorative portion covering the connection space of the panel roofing material and the panel roofing material, or the engaging portion elastically engaging with the engaged portion of the panel roof holding member or the cap holding member fixed to the panel roof holding member. Since the connection space of the panel roofing material is covered with a decorative cap provided with the above, the folded portion in the horizontal direction can be easily covered, and the rain finish and the design are improved.
