Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a roof panel. More specifically, the present invention improves the waterproofness of a roof panel integrated with roof tiles, which is effective for labor saving and cost reduction of roof construction for houses and the like, and a roof panel capable of improving the waterproofness of the roof part. It is about.

[0002]

2. Description of the Related Art Conventionally, a unitized roof panel has been studied in order to save labor and reduce costs for roof construction of a building such as a house. For example, there is known a roof panel in which roof tiles are arranged and fixed on the surface of a panel body that forms a roof surface. By installing this roof panel in parallel with the roof of the building,
A roof surface that is completely the same in appearance as a normal thatched roof is formed.

Since such a roof panel is arranged at the boundary between the outside and the building, it is exposed to wind and rain and is therefore sufficiently waterproof, as in the case of the building roof formed by the conventional method. It is recognized as one of the important technical issues to secure. Therefore, a roof panel having a structure as shown in the cross-sectional view of the main part of FIG. 11 has been considered so far.

In the roof panel shown in FIG. 11, a roof tile (4) which is arranged and integrated with a panel body (3) formed of a rafter (1), a ground plate (2) and the like.
Are laterally displaced from the panel body (3) and fixed. Then, in the roof panel adjacently arranged on the roof surface by the construction, the side end of the roof tile (4) protruding laterally from the side end of the panel body (3) is replaced with the side where the roof tile (4) is not arranged. Of the panel body (3) is disposed right above the surface of the side of the panel body (3), and by such an arrangement, the boundary portion (5) between the roof tiles (4) is formed directly above the surface of the panel body (3). I am trying.

Further, in this roof panel, the surface of the panel body (3) facing the side end portions of the roof tile (4) at the boundary portion (5) between the roof tiles (4) and in the vicinity thereof, that is, the ground plate (2). ) On the surface of a total of three sink bars (61) (62)
(63) are provided at predetermined intervals. As shown in the vertical cross-sectional view of FIG. 12, each of these sinking bars (61) (62) (63) is arranged in the direction from the ridge side of the roof to the eaves side during roof construction.

Further, the roof panel shown in FIG.
A drainer provided with four weirs (71) (72) (73) (74) on the surface of a sink bar (61) arranged farthest from the side edge of the panel body (3). A member (8) is also provided and is interposed between the roof tile (4) and the panel body (3). The draining member (8) is
It is made of an appropriate material such as waterproof metal.

For example, in the roof panel shown in FIG. 11 having the above-mentioned structure, even if water such as rainwater penetrates into the boundary portions (5) between the roof tiles (4) and falls on the surface of the panel body (3). Also, two weirs (72) (73) arranged in the central portion of the draining member (8) having waterproofness.
It is received by the recess formed between the two and suppresses diffusion to the surface of the panel body (3). Temporarily, weir (72) (73)
Even if water may accumulate above the height of the drain, the draining member (8) provided outside the weirs (72) (73)
The two weirs (71) and (74) near the sides of the tank block the outflow of water.

[0008]

However, even with such a roof panel in which waterproofness is taken into consideration, the roof tile (4) is thick such as a thick roof tile manufactured from an inorganic material such as cement. In the case where the roof tile (4) of the roof panel having the above-mentioned structure is used, as shown in FIG. 12, the back surface of the roof tile (4) and the sink rails (61) (62) (6) are used.
A gap (9) about the thickness of the roof tile (4) often occurs between the roof and (3). When the gap (9) is formed, as shown in FIG. 11, water such as rainwater that invades from the boundary (5) formed between the roof tiles (4) of the roof panels that are adjacently arranged by the construction , All of them do not fall into the recess between the two weirs (72) and (73) in the central part of the draining member (8), and some of the water (10) is gravitated due to its surface tension. It may move along the back surface of the roof tile (4) against it. Since the conventional roof panel is not provided with a member that prevents such movement of water, the water does not necessarily flow in the two weirs (71) near the sides of the draining member (8).
It does not always fall by (74). Therefore, there is a risk that water such as rainwater that enters from the boundary portion (5) between the roof tiles (4) directly drops onto the roof panel surface and wets the base plate (2) forming the surface portion. As a result, rain leaks will occur.

The present invention has been made in view of the above circumstances, and it is possible to improve the waterproofness of a conventional roof panel and to improve the waterproofness of a roof portion of a house or the like in which it is installed. The purpose is to provide a roof panel that can be integrated with roof tiles.

[0010]

In order to solve the above-mentioned problems, the present invention has a plurality of roof tiles, one side end of which is arranged directly above the surface of the panel main body and the other side end of which is the panel main body. A draining member that protrudes from the side end and is polymerized and integrated with the panel body by roofing is provided on the panel body surface from the side edge on the side that does not overlap with the roof tile directly above the panel body surface. The roof tile side edge immediately above the panel body surface is laid between the two weirs of the draining member. A roof panel in which the roof tile side end projecting laterally is arranged directly above the side end surface on the side where the roof tile is not arranged, of the panel main body that is adjacently arranged on the roof surface by construction. From the top to the back of the roof side edge Is formed into a shape corresponding to all the peripheral surface shapes, and has a body portion having an upper surface portion, a side surface portion, and a lower surface portion, and the water draining piece arranged between the adjacent weirs of the water draining member is a body lower surface portion. A roof panel characterized in that a brim member extending further downward is attached to a portion of the roof tile side edge portion which is not included in the overlapping width of the roof tile.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a roof panel according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of a main part showing a preferred embodiment of a roof panel of the present invention.

In the embodiment shown in FIG. 1, the basic structure is the same as that of the conventional roof panel shown in FIG. That is, a plurality of roof tiles (4) are superposed by roofing on a panel body (3) in which a base plate (2) is fixed to the upper surface of a rafter (1) which constitutes a frame by a fixing member such as a nail, and are integrated. It has become. The roof tile (4) has one side end arranged directly above the surface of the panel body (3), while the other side end projects from the side end of the panel body (3). It is arranged and fixed to the side from (3). By arranging the roof tiles (4) on the panel body (3) in this way, when constructing a roof part of a building such as a house,
In the adjacently arranged roof panels, the side end portion of the roof tile (4) protruding laterally from the side end portion of the panel body (3) is replaced by the panel body (3) on the side where the roof tile (4) is not disposed.
It is arranged so that it can be placed directly on the surface of the side end of the. With this arrangement, the roof panels that are adjacent to each other,
A boundary portion (5) between the roof tiles (4) is formed right above the surface of the panel body (3).

Further, in this roof panel, the surface of the panel body (3) facing the side end portions of the roof tile (4) at the boundary portion (5) between the roof tiles (4) and in the vicinity thereof, that is, the panel body ( 3) A total of three sinking bars (61) (62) (63) are provided at predetermined intervals on the surface of the field board (2) forming the surface portion. These sink bars (61) (62) (6
Similar to the conventional roof panel shown in FIG. 12, 3) is arranged in the direction from the ridge side to the eaves side of the roof portion during roof construction.

Further, in the roof panel, four weirs (7) are provided on the surface of the roof crosspiece (61) arranged at the farthest position from the side edge of the panel body (3).
1) (72) (73) (74) is provided with a draining member (8). The three weirs (7) of the draining member (8) that are not arranged at the side edges of the panel body (3)
2) The shapes of (73) and (74) are made to match the outer peripheral shapes of the flow bars (61) (62) (63). And these three weirs (72) (73) (74)
The draining member (8) is placed on the surface of the panel body (3) and fixed by covering the sinking bars (61) (62) (63).
However, it is interposed between the panel body (3) and the roof tile (4). Regarding such a draining member (8),
The material is not particularly limited as long as it has waterproofness, and can be formed from an appropriate material such as metal. Further, it is possible to manufacture by bending one plate material.

For example, in the roof panel having the above basic structure, when the roof tile (4) is thick such as a thick roof tile made of an inorganic material such as cement,
A gap (9) about the thickness of the roof tile (4) is often formed between the back surface of the roof tile (4) and the flow rails (61) (62) (63). Therefore, in the roof panel shown in FIG. 1, even when such a gap (9) is formed, the roof panel (4) adjacent to the roof panel by the construction is infiltrated from the boundary (5) between the roof tiles (4). A brim member (11) is provided so that water (10) such as rainwater does not diffuse along the back surface of the roof tile (4), and this is used as a roofing overlapping width of the roof tile (4) side edge portion. It is attached to a part not included in.

FIG. 2 is an enlarged perspective view of an essential part of the collar member. In the collar member (11) shown in FIG. 2, the skeleton part has a substantially U-shaped cross-section so as to match the peripheral surface shape from the front surface to the back surface of the side edge portion of the roof tile (4). It is molded, and the upper surface part (12) and the side surface part (13)
And the lower surface portion (14) is provided so that each is substantially perpendicular to the adjacent portion. Then, the side edge portion of the roof tile (4) shown in FIG. 1 is sandwiched in the space formed inside the body portion, and as shown in the perspective view of FIG. 3, the collar member (11) is The roof (4) side end portion is mounted and fixed to a portion that is not included in the overlapping width of the roof tile. In order to obtain a more reliable fixation, in this embodiment of FIG. 2, the side surface portions (1) in the body upper surface portion (12) and the lower surface portion (14) are
Protrusions (15) are provided on the lower end edge and the upper end edge opposite to 3).

The flange member (11) is also provided with a draining piece (161) extending downward at the lower end edge of the body lower surface portion (14) opposite to the side surface portion (13). This draining piece (161) is formed by two adjoining weirs of the draining member (8), as shown in FIG. 1, when the flange member (11) is attached to the roof tile (4) side edge portion. It is arranged in a recess that is closer to the side of the recess. Particularly, in the embodiment of FIG. 1, for the brim member (11) attached to the side end portion of the roof tile (4) arranged immediately above the panel body (3), the draining piece (161) is attached to the weir (73). A flange member (11) attached to the side end of the roof tile (4) protruding laterally from the side end of the panel body (3) while being hung in the recess formed between (74). ) For drained pieces (1
61) is hung in the recess formed between the weirs (71) and (72). Also, in such an arrangement, the drainage strips (161) are replaced by dams (71) (72) (7).
3) It is arranged to be parallel to (74). The material of the collar member (11) is not particularly limited as long as it has corrosion resistance so as not to corrode water, and an appropriate material such as metal such as aluminum can be adopted. The same applies to the manufacturing method thereof, and appropriate manufacturing techniques such as extrusion molding and bending can be applied. There is no special limitation.

For example, the collar member (1
In the roof panel of FIG. 1 in which 1) is attached to a portion of the roof tiles (4) that is not included in the roofing width, the roof tiles (4) of the roof panels that are adjacent to each other by construction will infiltrate from the boundary (5) between the roof tiles (4). Most of the water such as rainwater to be collected is located at the center of the water-draining member (8) having waterproofness.
3) Drop into the recess between them. On the other hand, due to the surface tension, some water (10) sneaking around the back surface of the roof tile (4) without falling against gravity and falling around the back surface (1) of the collar member (11).
Although it moves on the back surface of 4), it is drained by a draining piece (161) that hangs from the lower end edge thereof, and two adjacent weirs (73) (74) and weirs (7) of the draining member (8) are drained.
1) Drop into the respective recesses formed between (72) and near the sides. For this reason, it is possible to prevent water (10) from directly falling onto the roof panel surface, which is a problem in the conventional roof panel, and to effectively suppress the occurrence of rain leakage due to the wetness of the base plate (2). can do. This improves the waterproofness of the roof panel.

Further, the roof panel having the flange member (11) mounted thereon has the advantage that the flange member (11) enhances the strength of the side edge portions and improves the step cracking strength and the impact resistance strength. In addition, it is also possible to provide a plurality of draining pieces on the lower surface portion (14) of the collar member (11).

For example, as one form in that case, a collar member (11) provided with two draining pieces is shown in a perspective view of a main part of FIG. In the embodiment shown in FIG. 4, another drainer piece (162) is provided below the drainer piece (161) on the side surface portion (13) side and below the body lower surface portion (14). The draining piece (162) is hung down in a recess near the side portion of the draining member (8) similar to the draining piece (161), or depending on the number of weirs formed in the draining member (8), the draining piece (161) It is also possible to arrange | position in the recessed part rather than the center part rather than the recessed part in which a) is arrange | positioned. By disposing such a plurality of draining pieces, the draining piece (161)
Prior to, water (1) such as rainwater that infiltrated from the boundary (5)
0) can be drained by the draining piece (162), and the draining piece (16) farther from the side surface part (13) of the body can be drained.
The drainage by 1) can be made more reliable. The water (10) is further suppressed from flowing around to the back surface of the roof tile (4).

On the other hand, draining with a draining piece is performed by using water (1
Considering the evaporation of (0), the roof tiles (4) are bounded by each other (5)
It may be preferable to carry out within the range of. Therefore, in the embodiment shown in FIG. 5, the draining pieces (16) are arranged so that the draining pieces (161) are arranged within the range of the boundary portion (5).
(1) extends downward from the lower end edge of the side surface portion (13) side of the body lower surface portion (14), and is a recess formed by two weirs (72) (73) in the central portion of the draining member (8) I am trying to hang it.

However, depending on the strength of the wind, the water (10) may be pushed in by the wind blown from the boundary (5), and the pushed water (10) crosses the draining piece (161) and moves into the roof tile. Since the water moves along the back surface of (4), a situation may occur in which the water (10) that falls afterwards cannot be received by the draining member (8). The configuration shown in FIG. 6 can cope with such a situation.

The collar member (11) shown in FIG. 6 is similar to that shown in FIG.
The two draining pieces (161) (1
62), and the draining piece (161) is at the same position as the draining piece (161) in the configuration of FIGS. 2 and 4, that is, the lower end edge opposite to the side surface part (13) of the lower surface part (14) of the body. Has been extended to. On the other hand, regarding the draining piece (162), the draining piece (16) in the form of FIG. 5 described above is used.
As in 1), it is provided at the lower edge of the side surface portion (13) side of the lower surface portion (14) of the body. By doing this, while draining water (10) from the boundary (5) between the roof tiles (4) and accelerating the evaporation of the water (10) falling on the draining member (8), the draining of the water (10) is performed at the boundary ( It can be ensured regardless of the influence of the wind blown from 5).

That is, as shown in the cross-sectional view of the main part of FIG. 7, the water (10) such as rainwater that has infiltrated from the boundary (5) between the roof tiles (4) of the roof panels adjacent to each other by the construction is removed. Most of the water is drained by the draining piece (162) of the collar member (11) arranged within the boundary (5), and between the two weirs (72) (73) in the central portion of the draining member (8). It can be dropped into the formed recess. Falling water (10)
Is located within the boundary (5), its evaporation is fast,
The surface of the draining member (8) becomes easy to dry. For this reason,
It becomes difficult for water (10) to collect in the draining member (8),
As a result, corrosion is suppressed and the durability of the draining member (8) is increased.

Even if the wind blows into the boundary (5) and water (10) wraps around the back surface of the roof tile (4), the water (10 )
Since it can be drained by another draining piece (161), it hardly drops directly on the surface of the panel body (3). For example, as shown in FIG. 6, the collar member (11)
Draining piece (161) farther from the side surface part (13) of the body
If the length (l ₁ ) is longer than the length (l ₂ ) of the draining piece (162) arranged on the same plane as the body side surface part (13), the draining piece (161) is more drained. It will be more effective.

Furthermore, the roof panel of the present invention can be applied to roof wiring. For example, as shown in FIG. 8, roof tiles (4) integrated with wiring-requiring members (17) such as solar cells, antennas, and snow melting equipment have recently been used for the purpose of highly utilizing the roof of a building. Are being offered. Such a roof tile (4) is provided with a roof tile substrate (18) formed of an inorganic material such as cement that constitutes the base, and the wiring-requiring member (17) is set and fixed thereon. . Then, a roof panel is proposed in which the roof tile (4) integrated with the wiring required member is superposed on the panel body (3) by roofing, and the roof portion of the building and the wiring required member (17) are installed at the same time. , Is attracting attention as a means of further improving workability.

In the case of a roof panel integrally provided with such a wiring-requiring member (17) as well, in order to improve waterproofness, the collar member (11) is provided on the roof tile (4) side edge portion. It can be attached to a part that is not included in the roofing width. Moreover, in this case, the collar member (11) can be used for wiring the lead wire (19) extending from the wiring necessary member (17), and the roof substrate (1) of the wiring necessary member (17) can be used.
The function as a fixing member for fixing the installation to 8) can also be imparted.

That is, FIG. 9 shows a collar member (11) applicable to such a roof panel integrated with wiring-requiring members.
As shown in FIG. 1, the flange member (11) is formed in a substantially U-shaped cross-section that matches the peripheral surface shape of the side edge portion of the wiring required member (17) from the front surface to the back surface. It has a fixed part (20). This fixing portion (20) has an upper surface portion (21), a side surface portion (22), and a lower surface portion that are substantially perpendicular to adjacent portions, like the body portion of the collar member (11). However, for the lower surface part, the fixed part (2
In order to simplify the structure of (0), it is also used as the upper surface part (12) of the body of the collar member (11). In addition, the side surface (2
2) extends upward from the body side surface portion (13) of the collar member (11). In such a fixing portion (20), the side end edge portion of the wiring necessary member (17) shown in FIG. 8 is sandwiched in the space formed inside similarly to the body portion of the collar member (11). Thus, the wiring required member (17) can be fixed on the roof tile substrate (18). In this way, the flange member (11) is connected to the wiring required member (17).
It can also be used as a fixing member for the fixing part (2).
It is also possible to use 0) as a frame of the wiring-requiring member (17), the number of members can be reduced, and it contributes to the cost reduction of the wiring-requiring member-integrated roof panel. The fixing portion (20) may be provided with a ridge (15) similar to the skeleton portion so that the wiring-requiring member (17) can be more securely fixed. Such a ridge (15) has a side surface (2
It can be provided on one or both of the lower edge of the upper surface portion (21) located on the opposite side to 2) or the upper edge of the body upper surface portion (21) which also serves as the lower surface portion of the fixing portion (20).

Further, a wiring space (23) communicating with the outside is formed inside the collar member (11). More specifically, it is arranged at the farthest position from the side surface part (13) together with the upper surface part (12), the side surface part (13) and the lower surface part (14) which form the body part of the collar member (11), Each of the draining pieces (161) provided on the lower end edge of the lower surface portion (14) on the opposite side of the side surface portion (13) has an internal space formed along the shape thereof, which serves as a wiring space (23). In addition, the body upper surface portion (12) and the draining piece (16

In such a wiring space (23), a wiring path is formed which sequentially passes from the upper surface portion (12) of the skeleton body to the side surface portion (13), the lower surface portion (14) and the draining piece (161). It is possible to draw out the lead wire (18) extending from the wiring required member (17) as shown in (4) to the roof tile (4) rear surface side. That is, as shown in the perspective view of the main part of FIG.
The lead wire (18) extending from 7) is connected to the upper surface of the body (1).
It is sent into the wiring space (23) inside the collar member (11) from the wire passage hole (25) of 2), and inside the wiring space (23), the upper surface part (12), the side surface part (13) and the lower surface part of the skeleton body. After sequentially passing through (14), it is fed into the draining piece (161). Then, it is drawn out from the wire passage hole (25) formed in the side surface portion (24) farther from the body side surface portion (13). As described above, since the lead wire (18) can be pulled out to the rear surface side of the roof tile (4) through the collar member (11), a special member for pulling out the lead wire is not required, and the roof panel Will contribute to cost reduction. Further, the lead wire (18) can be pulled out by using the collar member (1
