Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a metal roofing plate manufactured from a thin steel plate, etc. This invention relates to an improvement of a horizontal reed type roof board in which an eave side molding part and a ridge side molding part are formed so that the parts engage with each other.

[Prior Art] A typical conventional roof board of this type is the one shown in FIG. 4 or 5.

$4 The roof plate (1) shown in the figure has an eave side engaging part (3) formed by folding back a part of the eave end of the flat face plate part (2) toward the ridge side on the back side. , Similarly, a ridge-side engaging part (4
), and as shown in the figure, the ridge-side engaging part (4) of the roof board (1) located on the eave side, and the eave-side engaging part (3) of the roof board (1) located on the surveying side. ) are interlocked and sandwiched together to move the plurality of roof plates (1) toward the eave ridge.
(1) is connected. This roof board (
In the case of 1), there are few steps caused by the engagement structure of each of the engaging portions (3) and (4), and a so-called flat roof with a smooth appearance is constructed.

Furthermore, the roof plate (11) shown in Fig. 5 has a face plate portion (
A hanging surface part (14) formed by bending a part of the eave side engagement 1i (13) formed at the eave side end part of 12) downward.
and an engagement protrusion 1 (15) formed by folding its lower end further toward the ridge side, and correspondingly an engagement protrusion 1 (15) formed at the probe end of the face plate (12) on the ridge side. Joint part (
16) includes a holding portion (
17), and an upright portion (18) formed to rise from the eaves side end of the holding portion (17). This roof plate (11) also has a plurality of roof plates connected in the direction of the eave ridge by holding the engaging protrusion (15) of the one located on the eave side to the holding part (17) of the one located on the exploration side. Constructs a horizontal roof.

[Problem to be Solved by the Invention 1] By the way, the required performances for such a roof structure are waterproofness (rain protection), load resistance, and appearance.

If we evaluate the roof board (1) in Figure 4 from this perspective, we can see that this roof board (1) is an orderly structure that constitutes a smooth, flat roof as described above, and also has a planar structure. Therefore, a strong roof surface can be formed depending on the roof's basic structure. However, due to the connection structure, problems tend to occur in terms of waterproofness. In other words, in order to ensure the required waterproof performance in a roof structure using this roof plate (1), it is necessary to check the eave side engaging part (3), the ridge side engaging part (4), and the position where they overlap during construction. It is necessary to crush the part of the face plate part (2) in the relationship so that they come into contact with each other with appropriate pressure. However, processing to apply such precise pressure is quite difficult, and if the crushing method is weak, gaps will be created between the joints of the various parts, making it easy for dirt and dust to enter, and of course, the waterproofness will deteriorate. Getting worse. In addition, if the crushing force is too strong, the gaps between the joints become too close and a capillary phenomenon occurs, causing rainwater etc. to be guided from the joints to the back side of the roof board (1) and cause rain leaks. It's put away.

On the other hand, in the case of a top-roofed roof made of roof plates (11) shown in FIG. 5, the waterproof problem seen in the flat-roofed roof is solved. That is, in this roof structure, the hanging surface portion (14) that forms the upright surface of the eave side engaging portion (13) is the mutually engaging portion ( Note that the part where adjacent roof panels overlap in this way is also called the "seam part".) Above the face plate part (12
) stand up the eave side ls part, and place a standing part (
18), so even if rainwater or the like enters from the engaging portion, the rainwater will flow into the space f! Rain does not enter inside 1S (19), but is guided and discharged laterally in the space (19), making it difficult for rain to leak indoors.

However, on the other hand, if a large space (19) is formed to ensure sufficient water retention, the height of the hanging surface (14) will naturally increase (height h in the figure), and the appearance will increase. There is a problem in that the roof has a noticeable difference in the upper level. Also, if the height of the hanging surface (14) is kept small so that the step is not noticeable, the space (
19) will become smaller, so the volume of the space (
19) becomes clogged with dirt and the like, making it easy for rain to leak due to capillary action. In addition, if the space (19) is too small,
When a strong wind blows from the side of the roof structure, the rainwater accumulated in the space (19) is blown up by the strong wind pressure, overcomes the upright part (18), and enters the indoor side. This problem also arises.

Furthermore, in this roof plate (11), a plate-shaped backup material (
20) is attached, and its eave side end is supported by the upper end of the upright part (18). However, in this structure, for example, a fibrous material such as sheathing insulation board is used as a backup material (20). If a hygroscopic material such as wood or veneer is applied, the space (
Since the backup material (19) sucks rainwater blown into the back-up material (19) from the end, a phenomenon similar to water leakage occurs. Moreover, if the backup material (20) becomes damp in this way, the quality of the backup material (20) will deteriorate, and its functions such as soundproofing and heat insulation will be lost in a short period of time. On the other hand, since the upright part (18) only supports a part of this backup material (20) near the eave side engaging part (13), the strength and rigidity of the face plate part (12) as a whole is is low;
As a result, a problem arises in that the roof plate (11) deforms when a strong load is applied due to snow accumulation or the like.

The present invention has been made by focusing on these conventional problems, and it is possible to maintain the soundproofing and heat insulating properties of the backup material for a long period of time, as well as having excellent water resistance and load carrying capacity, and also having an appearance that does not fit easily. An object of the present invention is to provide a horizontal roof board that can form a flat roof with few steps.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a face plate part in the longitudinal direction medium heat part of the long metal plate, and an eaves side molded part formed on one side of the face plate part. , in a roof board that has a ridge side molded part formed on the other side, and forms a horizontal roof by engaging and connecting the eave side molded part on the next stage to the ridge side molded part on the previous stage, The eave-side molded part includes an engagement protrusion formed by folding back the eave-side end of the face plate toward the ridge, and the ridge-splitting molded part includes a ridge fIllll end of the face plate. A holding part that is folded back toward the eave side on the upper surface side and is formed to hold the engaging protrusion of another roof board adjacent to the eave side, and the eave side end of this holding part and its upper surface. an extension part formed by folding back toward the ridge side at the side; an upright part formed upright from the extension part at a part closer to the ridge than the ridge end of the holding part; The top part is folded back to include a support part formed so as to come into contact with the back surface of the face plate part of another roof board adjacent to the eaves side, and a plate-shaped backup material is provided on the back surface of the face plate part.

[Function] With the above configuration, when a horizontal roof is constructed by covering a plurality of roof plates in the direction of the eaves, the engaging protrusion of the roof plate located on the eave side is connected to the other roof plates located on the ridge side. It is fitted into the holding part to form a first seam part. Also, at this time, the first
An upright part that stands up at a position closer to the ridge than the goby part,
The support portion located at the top of the support portion contacts and supports the back surface of the face plate portion of the ridge roof plate, and forms a second seam portion at the contact portion. Said 1st. Each second goby part is
They are spaced apart according to the length of the extension, and are long in the direction of the eaves.
Therefore, a sufficiently large space is defined. Further, the second ridge portion is located above the first ridge portion. Therefore, even if rainwater or the like enters the first bulge due to capillary action, the space will prevent it from reaching the second bulge, and furthermore, it will not run horizontally through the first bulge. Even if such strong wind pressure acts, the second seam is located deeper than the first seam, so even if the stagnant water is blown into the space, it will not reach the second seam. There is no possibility of leakage, as it can enter indoors through the air. Therefore, even if a water-absorbing material is used as a backup material, there is no risk of water leakage through the backup material, and the quality of the backup material will not deteriorate, so its soundproofing, heat insulation, etc. functions will last for a long time. maintained over the period.

On the other hand, as mentioned above, due to the upright part and the support part that stand up at the end of the extension part, the ridge roof board is supported at a part closer to the ridge than the end of the eave, and therefore the roof The strength and rigidity of the board as a whole are improved.

Further, since the space has a sufficient length in the direction of the eaves, a volume necessary for waterproofing can be secured, so that the vertical dimension of the upright part can be reduced by that amount. As a result, a flat roof surface with few steps can be obtained from this roof board.

[Example] Hereinafter, an example of a roof board according to the present invention will be described based on the drawings.

FIG. 1 is a side view of a roof structure covered using roof sheets according to this embodiment, and FIG. 2 is an enlarged view showing details of the connecting portion.

In FIG. 1 or 2, the roof plate (31) is made of a long steel plate of a predetermined width that has been painted with anti-rust baking, and is formed by using a roll forming machine etc. An eave side molding part (33) is attached to one end of the face plate part (32).
A ridge side molded part (34) is continuously molded on the other end side.

The eave side molded part (33) is formed by bending a hanging surface part (35) which is substantially perpendicular to the roof preparation surface downward from the eave side end of the face plate part (32), and this hanging surface part An engaging protrusion (36) is folded back from the lower end of (35) toward the ridge side. Note that (37) is the engagement protrusion (3).
6) is a bent edge part that is folded back, and in this case, it is finished in a manner that it is rolled up below the protrusion part (36),
Of course, it may also be formed upward.

On the other hand, the ridge-side molded part (34) has the ridge-side end part of the face plate part (32) folded back toward the eave side on its upper surface side, and is attached to another roof plate (31) adjacent to the eave side. A holding part (38) is formed to hold the mating protrusion (36), and this holding part (
A flat plate-shaped extension part (39) is formed by folding back toward the ridge side from the eave side end of the eave side end part (38). moreover,
From the end of the extension part (39) facing the stock system, it should stand up at the part of the stock system from the ridge side end of the holding part (38), that is, 122L in FIG. The upright portion (40) is raised substantially perpendicularly to the roof reference plane. Further, at the top of this upright portion (40), a support surface portion (41) is bent toward the eave side so as to abut against the back surface of the face plate portion of another roof plate (31) adjacent to the eave side.

In addition, in the roof board (31) of this embodiment, in addition to the above-mentioned configuration, the support part (4) of the other roof board (31) adjacent to the eave side is provided.
The side surface shape of the part closer to the eaves than the part supported by 1) is formed into a tapered shape in the direction of the eaves, and the hanging surface part (
35) by reducing its dimension in the northward direction.

Further, on the back side of the face plate portion (32), a backup material (46) made of a synthetic board material such as a control panel is provided.

This backup material (46) has a height equal to that of the upright part (40) and a thickness that is approximately concave, and is bonded in advance to the back surface of the face plate part (32) so that it is positioned more closely than the upright part (40). Either fix it with a roof plate, etc., or use a roof board (
31) so that it comes into contact with the back surface of the face plate part (32).

To assemble the roof panels (31) according to this embodiment into a roof structure, first place the roof panels (31) located at the end closest to the eaves on top of the rafters and sheathing boards (not shown) that form the basis of the roof structure.
Attach 1) using fixing tools such as hangers and nails. At this time, the backup material (46) is placed on the roof board (31) in advance.
If it is not fixed, it may be done as described above, or backup materials (46) may be laid on the base at appropriate intervals.

Next, the ridge side molded part (34) of this front side roof plate (31)
Then, the eave side molded part (33) of the next-level roof board (31) located in the stock system is engaged, and this next-level roof board (31) is also fixed using hangers or other fixing devices. Fix it to the roof base. Specifically, the engagement protrusion (36) of the eave side molded part (33) is inserted from the front inside the holding part (38) of the ridge side molded part (34), and the protrusion (36) is held. It is elastically sandwiched between the holding parts (38). At this time, in order to more firmly sandwich and fix the protruding part (36) in the holding part (38), it is necessary to
It is preferable to apply a preload by bending 8) sufficiently so that its lower surface is pressed against the upper surface of the face plate (32).

By performing this kind of work one after another from the eaves side to the stock system and connecting the required number of roof shingles (31),
It has a horizontal thatched roof.

In the state assembled in this way, the connecting parts of the roof plates (31) adjacent to each other in the direction of the eave ridge are connected to the holding part (38) and the engaging protrusion as shown in FIG. (
In addition to the first seam part (42) due to the engagement of 9
The support part (41) is the face plate part (32) of the eave side roof board (31)
A second ridge portion (43) is formed in a portion that abuts and supports the back surface of the holder.

Menki 1st. Each of the second goby parts (42) and (43) are
They are spaced apart by the length of the extension (39), in this case J2, to define a space (44) of sufficient volume. In addition, the second goby part (43) is a standing part (4) that corresponds to the water return.
0) and is located above the first gob part (42). As a result, as explained as an effect of the present invention, even if rainwater or the like enters the space (44) through the first bulge (42), it will not flow into the second bulge (43). The water does not enter the room through the water, but is guided to the side using the bottom surface of the space (44) as a drainage surface, and is discharged to the outside. In addition, even if strong wind pressure is applied to the inside of the first seam, the water stagnant inside will not be blown up and leaked indoors, resulting in extremely excellent waterproof performance. Ru. Since the space (44) effectively prevents rainwater from entering or blowing up indoors due to capillary action, a water-absorbing material is used as the backup material (46). However, it does not absorb moisture and cause water leakage, or quality deterioration due to corrosion etc., resulting in loss of soundproofing and heat insulation properties.

On the other hand, a standing portion (
40) and the support part (41), the roof board (31) located on the ridge side is supported at a part closer to the ridge than the end of the eave, and therefore the roof board as a whole It has improved strength and rigidity and exhibits sufficient resistance to loads such as snow accumulation.

In addition, since the space (44) has a sufficient length in the direction of the eaves, a volume necessary for waterproofing is secured, so that the vertical direction of the hanging surface part (35) and the upright part (40), etc. The dimensions can be reduced, and a flat roof surface with less noticeable steps can be obtained. In particular, in the roof plate (31) of this embodiment, the other roof plate (31) adjacent to the eave side
The side surface shape of the part closer to the eaves than the part supported by the support part (41) is formed in a tapered shape in the direction of the eaves, so that the apparent height of the stepped part is reduced. Therefore, a more orderly roof surface can be obtained.

Next, another embodiment of the roof board according to the present invention is shown in FIG. This is a mode in which a relatively thin back-up material (46) is prepared, and the eave-side end of the back-up material (46) is seated on the support part (41) of the roof board (31) similar to that shown in FIG. It was established in Assuming that the height of the upright part (40) that raises the support part (41) is the same, the thickness of the roof will be larger by the amount of backup material (46) placed on it compared to the one in Figure 1. However, if the backup material (46) is thin as shown in the figure, it will have little effect on the appearance. According to the roof sheet of this embodiment, the backup material (46) is supported by the support portion (41), and the area occupied by the backup material (46) on the back surface of the face plate portion (32) is the same as that of the upright portion (40). Since it is not limited by the support portion (41), it is possible to provide the roof plate (31) with soundproofing and heat insulating functions over a wider range.

[Effects of the Invention] As explained above, according to the roof board of the present invention, the first roof board is formed by the engagement protrusion of the roof board located on the eave side and the holding part of another roof board located on the ridge side. In addition to the goby part, this first
A second seam part located relatively upward is formed by a support part located on the ridge side of the seam part and the back surface of the face plate part of the ridge side roof board, and between these seam parts spaced apart in the direction of the eave ridge. Since a large space was defined in the first ridge, it would be possible for rainwater to enter the first ridge, and then receive strong wind pressure that runs sideways through the first ridge, causing rainwater to enter the space. However, there is no chance of rain entering the indoor area and causing leakage, and therefore extremely excellent waterproof performance can be achieved. Therefore, even if a water-absorbing material is used as a backup material, there is no risk of water leaking through the backup material, and the quality of the backup material will not deteriorate, so it can be used as a backup for soundproofing, heat insulation, load capacity, etc. Functionality is maintained over a long period of time.

In addition, in the roof board of the present invention, the upright part is raised at the end of the extension part extending from the first seam part to the ridge side, and the upright part and the support part formed at the top of the upright part allow the ridge side roof board to Since the roof is supported at the part closer to the ridge than the edge of the eaves, the entire roof plate has high strength and rigidity, which means it has sufficient load-bearing capacity to withstand heavy loads such as snow accumulation. is obtained.

Furthermore, according to the roof sheet of the present invention, each seam part is separated in the direction of the eave ridge, thereby securing the volume of the space necessary for waterproofing, so that the front and rear of the space can be increased accordingly. It is possible to reduce the vertical dimensions of the partitioning hanging surface portions and upright portions, that is, the step size that occurs on the roof surface, and therefore, a flat and orderly roof surface can be obtained.
