Description

TECHNICAL FIELD The present invention relates to a metal surface structural material manufactured from a steel plate or the like, which is suitable for forming a roof surface or a wall surface of a building, and more specifically, The present invention relates to a surface structural material for construction in which a lower molding portion and an upper molding portion are formed so that adjacent ones of both ends of a long metal plate having a predetermined width engage with each other.

[Prior Art] As a surface structure material that constitutes a roof surface in a lateral thatch type,
A roof plate as shown in the drawing or FIG. 5 is known.

The roof plate (1) shown in FIG. 4 has an eaves side engaging part (3) formed by folding back a part of the eaves side end of the flat face plate part (2) toward the ridge side on the back side. , A ridge-side engaging portion (4) which is also formed by folding a part of the ridge-side end toward the eaves side on the surface side, and as shown in the drawing, the roof plate ( The ridge-side engaging portion (4) of 1) and the eaves-side engaging portion (3) of the roof plate (1) located on the ridge side are engaged with each other and sandwiched between them, so that a plurality of ridge-side engaging portions are provided in the eaves ridge direction. The roof plates (1) and (1) are connected together. In the case of using the roof plate (1), a so-called thatched roof having a smooth appearance is formed with few steps caused by the engaging structure of the engaging portions (3) and (4).

The roof plate (11) shown in FIG. 5 has a face plate portion (12).
The eaves side engaging part (13) formed at the eaves side end part of the eaves side is formed by folding a part of the lower surface part (14) downward and the lower end part thereof further folded back toward the ridge side. It is composed of the engaging protrusion (15) and the face plate (12) corresponding to this.
The ridge-side engaging portion (16) formed at the ridge-side end of the holding portion (17) formed by folding a part of the ridge-side engaging portion (16) toward the eaves side so as to hold the engaging protrusion (15). ) And this holding part (17)
The rising part (1
8) and are provided. This roof plate (11) also has a plurality of roof plates connected to each other in the eaves direction by holding the engaging protrusion (15) of the eaves side of the roof plate (17) of the one located on the ridge side. To make a horizontal thatched roof.

[Problems to be Solved by the Invention]

By the way, what is important as the required performance for such a roof structure is waterproofness (rain proofing), load resistance, and appearance.

When the roof plate (1) of FIG. 4 is evaluated from such a viewpoint, the roof plate (1) is an orderly one that constitutes a smooth flat roof as described above, and has a planar structure. Therefore, a strong roof surface can be formed according to the basic structure of the roof. However, due to the connection structure, problems tend to occur in terms of waterproofness. That is, in order to ensure the required waterproof performance in the roof structure using this roof board (1), the eaves side engaging part (3) and the eaves side engaging part (4) and the position where they overlap with each other during construction. It is necessary to crush the part of the related face plate part (2) so that they are in contact with each other at an appropriate pressure.

However, it is very difficult to process to apply such an appropriate pressure, and if the crushing method is weak, a gap is created between the joints of the respective parts, and dust or dust easily enters, and of course, the waterproof property is also provided. Getting worse. In addition, when the crushing method is too strong, the gap between the joints becomes too close and a capillary phenomenon occurs, so that rainwater or the like is guided to the back side of the roof plate (1) from the connecting portion, causing rain leakage. It ends up.

On the other hand, in the side-roof with the roof plate (11) shown in FIG. 5, the problem of waterproofness found in such a flat-roof has been solved. That is, in this roof structure, the vertically lower surface portion (14) forming an upright surface in the eaves side engaging portion (13) is a part of the mutual engaging portion of the engaging protrusion (15) and the holding portion (17). Since the eaves side end of the face plate part (12) rises up and a large space part (19) partitioned by the upright part (18) is defined inside it, rainwater etc. from the engaging part Rainwater does not enter inside the space (19) and is guided and discharged laterally in the space (19), so it is unlikely that rainwater will leak indoors. .

However, on the other hand, if a large space (19) is formed to ensure sufficient water-tightness, the rising height (final height h in the figure) of the drooping surface (14) will naturally increase, resulting in a stepped appearance. There is a problem that it becomes a conspicuous roof. Also, if the height of the hanging bottom surface part (14) is kept small so that the step is not conspicuous, the space part (19) is correspondingly reduced.
Since the volume of the space becomes small, dust and the like are clogged in the space portion (19), and rain leakage due to a capillary phenomenon easily occurs. In addition, when the space portion (19) is too small, when a strong wind that laterally moves inside the engagement portion is received, turbulent flow occurs in the engagement portion due to the action of strong wind pressure, and the space portion ( Ten)
There is also the problem that rainwater that has penetrated into the building will be blown up, overcoming the standing part (19) and entering the interior.

Furthermore, in this roof plate (11), the engaging part is the eaves side engaging part (13).
There is also a problem that the coupling strength between the eaves side engaging part (13) and the ridge side engaging part (16) is weak because it is located inside the building and at a position separated in the ridge direction. In this case, the eaves side engaging part (13) in strong wind
Occurs, and at this time dust and dirt intrude from the engaging portion and accumulate, so that the weather resistance is impaired.
In addition, there is nothing for supporting the space portion (10) from the back surface side in this roof plate (11), and even if the top portion of the standing portion (18) is brought into contact with the back surface of the face plate portion (12), Since the abutting portion is limited to the vicinity of the eaves side engaging portion (13), there is a problem that the face plate portion (12) as a whole has low strength and rigidity. As a result, there arises a problem that it is deformed when a heavy load is applied due to snowfall or the like.

The present invention has been made in view of such conventional problems, excellent in wind pressure resistance, water resistance and load resistance, and,
It is an object of the present invention to provide a surface structure material that can form a smooth roof or wall surface that does not have a step in the engaging portion in appearance.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, a face plate portion is formed at a central portion in the longitudinal direction of a long metal plate, a lower forming portion formed on one side portion of the face plate portion, and an upper forming portion formed on the other side portion. And a lower surface side structural member for forming a surface structure by engaging and connecting an upper molding portion on the lower side with a lower molding portion on the upper side, the lower molding portion includes a lower end portion of a face plate portion from a lower surface side. The upper molding portion is provided with an engaging projection portion that is formed by being folded back, and the upper molding portion is formed by bending an upper end portion of a face plate portion so as to be substantially parallel to the engaging projection portion. And a holding portion formed by folding back the end portion to the upper surface side to hold the engaging protrusion of another surface structural material adjacent to the upper side, and further from the end portion of the holding portion to the holding portion. An extension portion formed by folding back on the upper surface side, and the extension portion above the holding portion. A rising-formed standing portion Luo,
A supporting portion that abuts the back surface of the face plate portion of another face structure material that is adjacent to the upper side at the top of this standing portion, and when these face structure materials are roofed together, insert along the inclined surface portion, etc. A first engaging portion is formed between the engaging protruding portion of the surface structural material and the holding portion fitted with the engaging protruding portion, and the supporting portion and the face plate portion with which the supporting portion abuts. The second engaging portion is formed between the two.

[Action]

With the above configuration, for example, when a plurality of surface structure materials are roofed in the eaves ridge direction to form a side-roof roof, the ridge side, that is, the engaging protrusion of the roof plate located on the upper tier side is located on the eaves side, that is, the lower tier side. The first engaging portion is formed by being fitted into the holding portion of another roof plate. In addition, at this time, the standing portion that has risen at a position closer to the ridge than the first engaging portion through the extension portion and the support portion that is located at the top of the standing portion are different from those of the other surface structural material that is located on the upper stage side. The back surface of the face plate portion is brought into contact with and supported by the back surface, and a second engaging portion is formed at the abutting portion. The first and second engaging portions are
They are separated according to the length of the extension and are long in the direction of the eaves, thus defining a sufficiently large space. Further, the second engaging portion is located above the first engaging portion. Therefore, even if rainwater or the like enters the first engaging portion due to the capillary phenomenon, it does not reach the second engaging portion due to the space, and further traverses the first engaging portion. Even if such a strong wind pressure acts, since the second engaging portion is located at a position deeper than the first engaging portion, even if retained water is blown into the space, This is the second
There is also no possibility of rain leaks caused by the intrusion into the indoor side through the engaging portion of.

In particular, in the present invention, the engaging protrusions of the other surface structural material adjacent to the upper side are sandwiched between the inclined surface portion and the holding portion provided in the upper molding portion, so that these engaging portions High strength is secured, and therefore, the lifting phenomenon during strong wind and rain is suppressed.

On the other hand, as described above, due to the rising portion and the support portion which are raised at the end of the extension portion, the surface structural member located on the upper stage side is supported at a portion somewhat higher than the lower end portion thereof, Therefore, the load bearing performance of the entire surface structure material is improved.

Furthermore, since the space has a sufficient length in the vertical direction (eave building) to secure a volume necessary for waterproofing, the thickness of the entire surface structure can be reduced accordingly. Furthermore,
In a state where the engaging protrusion of the surface structure material located on the upper stage side is engaged with the holding portion of another surface structure material located on the lower stage side, the face plate portions of both surface structure materials of the connecting portion are the same. Since the surface is formed, it is possible to form a smooth structure surface without the step.

In addition, because of such a structure, each face structural material has its face plate portion parallel to the construction foundation face, for example, the ground plate. It is sufficient to apply a material having a uniform thickness as it is, and therefore, the strength, heat insulation and soundproofing of the surface structure material can be improved very easily.

〔Example〕

An embodiment in which a side-roofed roof is made of a surface structure material according to the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a roof structure roofed by using a surface structure material according to this embodiment, and FIG. 2 is an enlarged view showing details of a connecting portion thereof. The alternate long and short dash line in the figure indicates the reference plane of the roof made of a base material such as a ground plate.

In FIG. 1 or 2, the surface structural material (31) is made of, for example, a long steel plate of a predetermined width that has been baked for rust prevention, and is formed by a roll forming machine or the like to have a flat center. The lower molding portion (33) is provided at one end of the face plate portion (32) facing the eaves (hereinafter referred to as the eaves-side end), and the other end portion also facing the ridge (hereinafter, the ridge-side end). Upper molding part (3
4) are formed continuously.

As shown in FIG. 2, an engaging protrusion (36) is folded back from the eave side end of the face plate portion (32) toward the lower inside of the lower molding portion (33). When the surface structural material (31) is used as a roof plate as described above, the angle θ _a formed by the engaging protrusion (36) with the face plate part (32) is the angle θ _a formed by the roof reference plane with respect to the horizontal plane. _It is preferable from the viewpoint of waterproofing that it is made smaller than _b so that the engaging protrusion (36) inclines toward the eaves in the roof surface configuration state. In addition, (37) is the engaging protrusion (36)
It is an edge-bending portion obtained by folding back the edge portion of the above, and in this case, it is finished in a form in which it is wound below the projecting portion (36), but it may of course be formed above.

On the other hand, in the upper molding portion (34), the ridge-side end portion of the face plate portion (32) is bent toward the reference surface side so as to be substantially parallel to the engaging protrusion (36), and the inclined surface portion ( 35) is formed, and its end is folded back toward the eaves on the upper surface side, and the engaging protrusion (36) of another surface structure material (31) adjacent to the upper side is formed.
A holding portion (38) is formed to hold the. In addition, a flat plate-shaped extension (39) is formed by folding back from the end of the holding portion (38) on the eaves side to the ridge side again on the upper surface side. In this case, the extension portion (39) is formed so as to descend along the inclined surface portion (35) and then extend in the ridge direction along the reference surface. Furthermore, from the end of the extension part (39) facing the ridge, the end of the holding part (38) rises at a part closer to the ridge than the end on the ridge side, that is, l ₂ ≧ in FIG. The rising part (40) is set up so that it becomes l ₁ . In addition, at the top of the standing portion (40), another surface structure material (3
The support portion (41) is formed by bending toward the eaves so as to contact the back surface of the face plate portion of 1). (50) is a suspension, (51)
Is a suspension (50) or upright (40) and backup material (45)
It is a gap between and.

In order to assemble the surface structure material (31) according to this embodiment into a roof structure, first, the surface structure material that is located at the end closest to the eaves is first placed on the rafters or field boards (not shown) that form the basis of the roof structure. Attach (31) by using fasteners such as suspenders and nails.

Then, the lower molding portion (33) of the upper side surface structural material (31) located on the ridge side is engaged with the upper molding portion (34) of the surface structural material (31) located on the lower step side, Upper side structure material (31)
Also, fix it on the roof foundation using a fixture such as a suspension. Specifically, the engaging protrusion (36) of the lower molding portion (33) is inserted from the front into the holding portion (38) of the upper molding portion (34) to hold the protrusion portion (36). Fit in (38).

By performing such work one after another from the eaves side to the ridge side, and connecting the required number of surface structure materials (31),
The thatched roof is constructed.

Then, in the state assembled in this way, the connecting portion of the plurality of surface structure materials (31) adjacent to each other in the eaves ridge direction has the surface structure material adjacent to the ridge side as shown in FIG. The engaging projecting portion (36) of the (31) is sandwiched between the inclined surface portion (35) of the surface structure member (31) and the holding portion (38) located on the eaves side, and has a multiple structure. The second engaging portion (42) is formed, and the supporting portion (41) abuts against the rear surface of the face plate portion (32) of the ridge side surface structural material (31) to support the second portion. An engaging portion (43) is formed.

The engaging portions (42) and (43) have the length of the extension portion (39),
Space of the case spaced apart the length amount corresponding l ₂ sufficient volume (4
4) is defined. Further, the second engaging portion (43) is located at the top of the standing portion (40) that is in contact with the water return and is located above the first engaging portion (42). As a result, as described as the operation of the present invention, the first engaging portion (4
Even if rainwater or the like enters the space (44) via 2), it does not enter the indoor side via the second engaging portion (43), and the space (44) The damaged surface, that is, the upper surface of the extension (39) is used as a drainage surface to be guided laterally and discharged to the outside.

In addition, as described above, since the first engaging portion (42) having a multiple structure is formed at the eave-side tip of the surface structure material (31), the coupling strength of this portion is extremely high, and therefore strong wind pressure is applied. Even if it acts, it does not lift up, and dust and dirt are prevented from entering the engaging portion. Further, even if rainwater enters the space (44), it is difficult to wind it up due to wind pressure, so that extremely excellent waterproofness is exhibited.

On the other hand, the upright part (4
The surface structure material (31) located on the ridge side is supported by the part (0) and the supporting portion (41) at a part on the ridge side rather than the eaves side end thereof, and thus the entire surface structure material. Its strength and rigidity are improved, and it exhibits sufficient resistance to a load such as snow. Particularly, in this embodiment, since the back-up material (45) having a thickness corresponding to the height of the surface structure material (31) is provided on the back surface of the face plate portion (32), the back-up material (45) is provided. Due to this, a high degree of rigidity can be maintained over the entire face plate portion (32), and excellent heat insulating properties and soundproofing properties are exhibited.

The space (44) has a sufficient length in the direction of the eaves to secure a volume necessary for waterproofing, and therefore the vertical dimension of the inclined surface portion (35) and the upright portion (40) is correspondingly secured. The thickness of the backup material (45) can be minimized to that extent. Furthermore, in a state where the engaging protrusion (36) of the surface structure material (31) located on the ridge side is engaged with the holding portion (38) of another surface structure material (31) located on the eaves side, Face plate portions (3) of both face structure materials (31) of the connecting portion.
Since 2) composes the same surface, it is possible to form a very smooth roof surface without steps.

By the way, in the above-mentioned surface structure material (31), the bonding strength and weather resistance thereof can be further improved by subjecting the first engaging portion (42) to simple processing as described below.

This is because a preload is set on the first engaging portion (42). That is, the inclined surface portion (35) and the holding portion (38) are preliminarily flexed so that they are elastically contacted with each other at a predetermined pressure, and another surface structure material (31) is provided in the ridge direction. At the time of connection, the engagement protrusion (36) is elastically sandwiched between the inclined surface portion (35) and the holding portion (38). As a result, a stronger connecting force is exerted between the lower molding part (33) and the upper molding part (34), and the roof surface is lifted up under the action of strong wind pressure, and the intrusion of dust and the leakage of rain due to this are further ensured. Can be prevented.

Next, the third embodiment of the surface structure material according to the present invention will be described.
It will be described with reference to the drawings.

When forming the lower molding portion (33), the lower end portion of the face plate portion (32) is bent vertically downward once to form the hanging lower surface portion (36A), and the lower end portion of this hanging lower surface portion (36A) is engaged. The protrusion (36) is folded back. Vertical surface (36
The upper and lower (eave building) direction of A) is the engagement protrusion (36)
The holding portion (38) of the other surface structure material (31) located below
So that it is positioned a little more than the starting point (q) of the inclined surface part (35) of the other surface structure material (31) adjacent to the lower part in the state of being inserted into the above and connected to each other. The height is determined so as to fill the head gap formed between the inclined surface portion (35) and the inclined surface portion (35) at this time to form a flush state.

According to the surface structure material (31) of this embodiment, when the roof surface or the like is formed, the groove-like portions in which the vertically lower surface portion (36A) is retracted from the smooth surface are formed at equal intervals. Individuality can be added to the roof surface as an upper accent. Further, since the face plate portions (32) of the plurality of face structure members (31) adjacent to each other are slightly separated by the groove-like portion, the face plate portions (32) adjacent to each other due to irregularities of the base portion ( 32) Even if there is a difference in height, this has the effect of not being visually noticeable. Since the other points are substantially the same as those of the first embodiment, the same reference numerals are given to the same portions in the drawings and the description thereof will be omitted.

In addition, although the embodiment shows an example in which the surface structure material according to the present invention is mainly applied to a roof structure, it goes without saying that the present invention is not limited to such a roof structure and may be applied to a wall surface of a building. it can.

〔The invention's effect〕

In addition to the joining portion, a supporting portion located above the first engaging portion,
Since the second engaging portion located relatively upward is formed by the back surface of the face plate portion of the upper side surface structural member, and a large space is defined between the engaging portions separated in the vertical direction. , Even if rainwater, dust, etc. enter the first engaging part, and even if strong wind pressure such as lateral running inside the engaging part is received, the rainwater, etc. entering the space will move to the indoor side. It does not cause rain leaks, and therefore extremely excellent waterproofness is obtained.

Particularly, in the present invention, between the inclined surface portion provided in the upper molding portion and the holding portion, the engaging protrusion of another surface structure material adjacent to the upper side is sandwiched so that the engaging portion of the multiple structure is formed. Since it is formed, it is necessary to secure strong strength in these engaging parts and suppress the lifting phenomenon of the surface structural material during strong wind and rain, and effectively prevent the accumulation of dust and rain leakage due to this lifting phenomenon. You can

Further, in the surface structure material of the present invention, the upright portion is raised at the end of the extension portion extending above the first engaging portion, and the upright portion and the support portion formed on the top portion of the upright portion make Since the surface structure material is supported at a portion slightly higher than the lower end portion, high strength and rigidity can be imparted to the surface structure material as a whole, that is, sufficient withstand load that can withstand heavy loads such as snow. Sex is obtained. It should be noted that higher strength and rigidity can be obtained when a backup material is provided on the back surface of the face plate portion,
At this time, since the backup material having a uniform thickness can be applied as it is, the strength, heat insulating property, and soundproofing property of the roof and wall surfaces can be improved very easily.

Further, according to the surface structure material of the present invention, since each engaging portion is configured to be separated in the eaves ridge direction, a space volume required for waterproofing is secured, so that the front and rear of the space is increased accordingly.
