Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to horizontal roofing sheets made of metal steel sheets, and more specifically, the present invention relates to horizontal roofing sheets made of metal steel sheets, and more specifically, a long metal steel sheet of a predetermined width that is coated with a coating for rust prevention. A horizontal roof board in which predetermined eave side nine building side engaging parts are formed in advance on both ends of the roof for mutual engagement, and in particular, improvement of the shape of each eave side and one building side mutual engaging part. This is related to.

[Conventional technology]

Up until now, many different types and 8 types of horizontal roof panels made of long metal steel sheets have been proposed, and among them, rain-covering roof panels have been proposed.

That is, there is active development of a combination engagement part shape intended to prevent rainwater from entering from the eave side two building side engagement parts that are engaged and connected to each other.

Figures 7 and 8 show conventional examples of connection shapes at each of the engagement portions on the nine eave sides, which are generally adopted for such horizontal roof panels made of long metal steel plates. Shown below.

Fig. 7 is a cross-sectional perspective view showing the horizontally-stitched roof board according to the conventional example, and Fig. 8 is an enlarged cross-sectional view showing the connected and engaged state of the nine eaves-side engaging parts using the horizontally ruled roof board. be.

In the conventional examples shown in Figs. 7 and 8, horizontal roofing plates (1
), for example, a long metal steel plate of a predetermined width that has been painted is used for anti-corrosion baking, and this metal steel plate is processed using a roll forming machine or the like, leaving a face plate part (2) in the center along the longitudinal direction.
An eave side molded part (3) is continuously molded on the negative side, and a ridge side molded part (4) is continuously molded on the other side.

Therefore, the eave side molded part (3) includes the face plate part (2).
Bend the crown (5) diagonally outward and downward to a predetermined length from the side of 7) is folded inward in an upward arc to form a folded portion (8), and this folded end is formed into an edge-bending portion (8).

Further, the ridge side molded part (4) is configured to hold the edge bent part (9) from the other side of the face plate part (2).
The holding part (10) is bent diagonally inward and upward, and furthermore, the protruding piece part (11) is made to rise upward from the tip thereof, and the protruding edge (12) is made to protrude inwardly and downwardly. .

In this conventional example, the horizontal roof board (1) on the rafter (13), which is on the eaves side, in this case the front side, is placed on the rafter (13).
With the wooden wool board (14) as a buffer material placed in the inner space, it is attached using, for example, a well-known hanger, and then the front side horizontal roof board ( The eave side molded part (3) of the next horizontal curtain roof board (1) on the ridge side is engaged and connected to the ridge side molded part (4) of 1), and this engagement assembly is carried out on the eave side. From the ridge side, that is, from below, the desired horizontal thatched roof was raised.

That is, more specifically, the folded part (8) is inserted into the holding part (10) so that the eave side molded part (3) of the next stage is fitted into the ridge side molded part (4) of the previous stage. Edge bending part including a part (
9) are inserted and engaged, and the inner surface of the falling portion (6) is abutted against and connected to the projecting edge (12). In this engaged and connected state, the edge bending portion (9) is inserted into the holding portion. (10), the lower edge (7) of the falling part (6) is brought into line contact with the surface of the face plate part (2), and the upward curvature of the folded part (8) First decompression space (15
), a second decompression space (1B) in the holding part (lO)
, and a third decompression space (17) is formed between the falling portion (6), the protruding piece portion (11), and the protruding edge (12).

In other words, as is clear from the conventional structure, the basic concept of the conventional engagement connection structure at each engagement part on the eaves side is that the ridge raised from the face plate part (2) on the front side With respect to the side molded part (4), the eave side molded part (3) is lowered from the next stage side face plate part (2), and the engaging abutment part (18) exposed to the outside is connected to the same face plate part. (2) Fit and engage so that there is a state of line contact on the surface to prevent rainwater from entering 1F from the engaging surface and to reduce the pressure of rainwater entering into each depressurized space. That's how I do it.

[Problem that the invention seeks to solve]

As you can see, in the conventional horizontal roof structure made of long metal steel plates, as described above, the engagement abutting portions (1B) of the nine eaves side engagement portions (3) and (4) However, since it is located at the corner of the inner corner that stands up at a right angle to ζ when touching the face of the face plate (2), in the case of strong winds and rain, the wind blows along the roof slope of the face plate (2). ”The wind and rain naturally cause the engagement abutment portion (18
), and strong wind and rain pressure is applied especially to the vicinity of this engaging abutment part (18), and the wind and rain that blows on it bounces upward along the falling part (8). flows.

At this time, the engagement butt portion (18
), it is found that at this engagement butt part (18), the wind and rain pressure that is directly blown on the abutment part (18),
The wind and rain pressure that jumps upwards and the combined pressure of these pressures are applied.

Therefore, in this case, on the one hand, depending on the wind and rain pressure that is applied directly, there is a risk of water intrusion from the engaging abutment part (18) into the interior of the roof due to capillary action. Conventionally, in order to avoid this capillary phenomenon as much as possible, in the engagement abutment part (18), generally, surface contact at this point is avoided, and the abutment structure by line contact as described above is used. However, on the other hand.

Depending on the wind and rain pressure that jumps upward and these combined pressures,
An effect occurs that causes the falling portion (θ) to float upward, and together with the fact that the engagement abutment portion (18) is just a line contact, the contact on the same surface is pushed open. This has the disadvantage that the gap between the butts becomes larger, further increasing the risk of water seeping into the interior.

Therefore, an object of the present invention is to improve the cross-sectional shape of each of the above-mentioned nine eave-side engaging portions to effectively prevent the infiltration of rainwater, and to have high structural strength and easy assembly. The purpose is to provide horizontal roofing sheets.

[Means for Solving the Problems] In order to achieve the above object, the horizontal roofing plate according to the first aspect of the present invention has a face plate part in the longitudinal center of the long metal steel plate, and a face plate part of this face plate part. Each side has a lowered eave side molded part and an upright ridge molded part on the other side, and the eave side molded part on the next stage is engaged and connected to the ridge side molded part on the previous stage. In the horizontal roofing plate constituting the horizontal roof, the eave side molded part includes a falling part hanging down from the face plate part, and a lower side part bent laterally inward from the lower edge of the falling part, An inner upright portion raised from the lower side portion and an engagement projection portion bent laterally inward from the inner upright portion are respectively formed, and the ridge side molded portion includes a face plate portion against which the lower side portion abuts. an outer upright part that is raised from the outside and faces the inner upright part with a gap therebetween; and an outer upright part that is bent laterally inward from one end edge of the outer upright part and faces the face plate part with a gap in between. Raise the extension part and the end of the extension part,
an abutment part that abuts against the upper part of the inner upstanding part; and an engagement clasp that is bent laterally outward from two end edges of the abutment part and folded back at the end to receive the engagement protrusion in a contact state. With the ridge side molded part on the previous stage engaged and connected to the eave side molded part on the next stage, the two-face plate part of the inner upright part, the outer upright part, and the extension part are formed. The horizontal roof plate according to the second aspect of the present invention is characterized in that a depressurized space surrounded by each of the Each side has a face plate part, an eave side molded part that is lowered down on one side of this face plate part, and a ridge side molded part that is raised up on the other side, and the eave side molded part on the previous stage side is attached to the eave side molded part on the next stage side. In a horizontal roof board in which side molded parts are engaged and connected to form a horizontal roof, the eave side molded part has a falling part that hangs down from the face plate part, and a lateral inner side from the lower edge of the falling part. A lower side portion bent to the side, an inner standing portion raised from the lower side portion, an engagement recess provided in the upper part of the inner riser portion, and an engagement portion bent laterally inward from the engagement recess. The ridge-side molded part has an outer upright part that stands up from the face plate part against which the lower side abuts, and faces the inner upright part with a gap therebetween, and an outer upright part. An extending portion is bent laterally inward from the upper end edge of the upright portion and faces the face plate portion with a gap therebetween, and an end portion of the extending portion is raised to abut/contact with the engagement recess. an abutment portion to be engaged, and an engagement holding portion that is bent laterally outward from one end edge of the abutment portion, and the end portion is folded back to receive the engagement protrusion in a contact state. With the ridge side molded part on the previous stage engaged and connected to the eave side molded part on the next stage, the inner raised part is surrounded by the two-face plate part, the outer raised part, and the extended part, respectively. The present invention is characterized in that a depressurized space can be constructed.

[For production]

That is, in this invention, the lower side of the front ridge side molding part is
While in surface contact with the face plate part that is close to the next stage eave side molding part, the inner upright part is opposed to the outer upright part with a gap between them, and the abutment part is abutted against the upper part of the outer upright part, or The abutment part is abutted/contactly engaged with the engagement recess on the upper part of the outer upright part, and the engagement protrusion is received in contact with the engagement holding part to engage and connect, Since a sealed decompression space surrounded by each of the outer standing portion and the extension portion is formed, the presence of the decompression space with a large internal volume that is sealed makes it possible to create a space between the lower side and the extended portion. Even if the face plate part is brought into surface contact with the face plate part, water intrusion from the contact part of these parts can be effectively avoided, and in the depressurized space part, the engaging contact part is in contact with the abutting part at the upper part, The contact portion of the engaging protrusion in the subsequent engaging holding portion is inserted.

Since the protection is formed by double surface contact, even if a small amount of water floods into this decompression space, there is no risk of water flooding beyond this area. It is also resistant to flooding due to snow, so there is no need to worry about so-called fog.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of horizontal roofing panels according to the present invention will be described in detail below with reference to FIGS. 1 to 6.

FIG. 1 is a cross-sectional perspective view showing a roofing board according to a first embodiment of the present invention, and FIG. FIG.

In the configuration of the first embodiment shown in FIGS. 1 and 2, the horizontal roof plate (21) has the same structure as in the conventional configuration described above.
For example, baking for rust prevention uses a long metal steel plate of a specified width that has been painted, etc., and this metal steel plate is processed using a roll forming machine, etc.
Leaving the face plate part (22) in the central part along the longitudinal direction, an eave side molding part (23) is formed on the negative side of the face plate part (22), and a ridge side molding part (20) is continuously formed on the other side. It's a shame.

Therefore, the eave side molded part (23) has the face plate part (23).
From the - side of 2), bend the crown part (25) slightly diagonally outward and downward to a predetermined length, and then let the falling part (28) fall downward from the tip of the crown part (25). Lower edge (2
7) inward in the horizontal direction to form a lower side part (28), and from this lower side part (28) in the vertical direction an inner standing part (28) is formed.
), and further, from this inner upright part (28), an engaging protrusion (30) whose end is bent (31) inward in the lateral direction.
It is formed by bending it.

The ridge side molded part (24) also has the lower side part (28).
an outer upright part (32) that faces the inner upright part (29) with a gap from the face plate part (22) on the other side that abuts the inner upright part (29);
is raised, and its upper edge (33) is bent laterally inward to form an extension (34) opposed to the face plate (22) with a gap therebetween; Debe (34
) from the end of the abutment part (35) that abuts against the upper part of the inner upright part (29) in the vertical direction, and then from the upper edge of this abutment part (35) laterally outwardly. Engagement holding part (3B) that receives the mating protrusion (30) in surface contact state
The end part (38) is folded back and bent to further distance the internal space from the dividing protrusion part (37), and the end part (38)
26) is formed so as to protrude curvedly toward the inner surface side.

Although not shown in the drawings, the horizontally ruled roof board (21) according to this embodiment is installed on the rafters as metal fittings, and first installed on the eaves side. The first horizontally ruled roof board (21) is attached with a hanger or the like with a wood wool board or the like as a back-up material appropriately placed inside the inner space.

Next, the ridge side molding part (
24), the eave side molding part (23) of the next horizontal ruled roof board (21) on the ridge side is moved to the face plate part ( 22), the inner upright part (29) is opposed to the outer upright part (32) with a gap in between, and the abutting part (35) is placed on the upper part of the outer upright part (32). Abutting and engaging protrusion (3o
) is tightly received in the engaging holding part (36) in a state of surface contact and engaged and connected, and by this engaging connection, the inner rising part (2
9) A sealed decompression space (39) is formed which is surrounded by the face plate part (22), the outer standing part (32), and the extending part (34), and then this The roofing is done sequentially from the eaves side to the ridge side, that is, from the bottom.

Further, FIG. 3 is a cross-sectional perspective view showing a roofing board according to a second embodiment of the present invention, and FIG. 4 is an enlarged view showing the connected and engaged state of the nine eaves-side engaging portions of the same roofing board. A cross-sectional view,
In each figure of this second embodiment, the same reference numerals as in each figure of the first embodiment indicate the same or corresponding parts.

That is, in the configuration of the second embodiment shown in FIGS. 3 and 4, there is a
An engaging recess (40) is formed in which the abutting part (35) is tightly fitted into and engaged with the abutting part (35) in a state of surface contact, and the abutting part (35) is inserted into the engaging recess (40). The engagement assembly-L is exactly the same as in the case of the first embodiment, including the engagement.
It is possible to do so.

Therefore, in the case of each of these embodiment configurations, in the former first embodiment, each of the horizontally ruled roof plates (3I) on the front eave side 9 building side rear tier, which are connected and integrated with each other, Close to the ridge side molding part (24) on the front stage side that is exposed to the outside (
The joining by two-sided contact between the angled face plate part (22) and the lower side part (28) of the eave side molded part (23) on the rear side that abuts against this face plate part (22) is the same joint. A decompression space (with a relatively large internal volume that is sealed inside)
38), wind and rain pressure blowing onto the concave contact area is effectively inhibited, partly due to the resistance element based on the closed internal pressure within this reduced pressure space (38), and the wind and rain pressure blown onto the concave contact area is easily blocked through this area. Rainwater does not infiltrate, and the separation effect of the contact portions due to wind and rain pressure is also sufficiently reduced, making it possible to join by such surface contact.

In addition, in this decompression space (39), subsequent engagement contact portions include a surface contact of the abutment portion (35) on the upper side of the inner upright portion (29), and a subsequent engagement protrusion ( 3o)
Since the joint is made by double surface contact with the reception by surface contact state into the engaging holding part (3B),
Even if a small amount of water intrudes into the reduced pressure space (39) due to capillary reduction due to the pressure difference between the inside and outside, the rainwater reduced in pressure by infiltration into the large internal volume will flow through these double surface contact areas. There is no risk of water leaking into the roof by passing through the roof, and on the other hand, due to the individual bending structure of each engaging part, this engaging part itself can be made smaller, reducing the overall height. This makes it possible to reduce the amount of friction, and at the same time, the strength of the engagement structure can be significantly improved.

Also, in the latter second embodiment, in addition to obtaining the same functions and effects as those of the former first embodiment, the abutting portion ( 35), further water leakage prevention effect can be obtained.

Furthermore, the third embodiment shown in FIG. 5 is the same as the second embodiment in which the segmented protrusion (37) is doubly curved and protruded, and the third embodiment shown in FIG. Similarly, in the second embodiment, the end portion (38) of the sectioning protrusion (37) is curved in the opposite direction, and the same functions and effects can be obtained in each of these embodiments.

〔Effect of the invention〕

As detailed above, according to the present invention, there is a face plate part in the longitudinal center of the long metal steel plate, an eaves side forming part that is lowered down on one side of this face plate part, and a ridge side that is raised on the other side. In a horizontal roof board, each of which has a molded part, and in which the ridge side molded part on the previous stage is engaged with the eave side molded part on the next stage to form a horizontal roof, With the lower side of the ridge side molded part in surface contact with the face plate part near the next stage eave side molded part, the inner upright part faces the outer upright part with a gap between them,
The abutment part is abutted against the upper part of the outer upright part, or the abutment part is brought into abutting contact engagement with the -1 part of the engagement recess of the outer upright part, and the engagement protrusion is brought into contact with the engagement holding part. By accepting the contact state and engaging and connecting, the inner rising part 9 face plate part,
Since a sealed decompression space surrounded by each of the external upright part and the extension part is formed, the presence of the decompression space with a large internal volume that is kept in a sealed state prevents contact between these two parts. This makes it possible to effectively avoid water intrusion from the lower part and the face plate part, and in the depressurized space part, the engagement contact part can prevent water from entering the inner raised part at the upper part of the space. The abutment of the abutment part or the abutment of the abutment part to the engagement recess, and the subsequent contact amount of the engagement protrusion at the engagement holding part are protected by double surface contact with the insert. Therefore, even if a small amount of water floods into this depressurized space, there is no risk of water flooding beyond this area and leaking into the roof, and there is no surface contact at each of these engaging parts. As a result, the height of the engagement structure itself can be reduced to make it as compact and compact as possible, and it also has the advantage of being constructed as a rigid structure with high strength. It has excellent features such as being able to assemble and connect and engage accurately and easily, and also being structurally extremely simple and easy to implement. It is also resistant to flooding due to snow, and there is no risk of so-called drowning.
