Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to horizontal roofing sheets made of metal steel sheets, and more specifically, anti-corrosion baking is performed on long metal steel sheets of a predetermined width that are coated with paint or the like. Horizontal roofing boards with predetermined engagement parts on both sides of the eaves for mutual engagement, particularly for improving the shapes of the engagement parts between the nine eave sides. This is related.

[Conventional technology]

Traditionally, there have been various types of horizontal roofing panels made of long metal steel sheets.

Many shapes have been proposed, and among them, combination engagement part shapes are being actively developed with the aim of preventing rainwater from entering from the eave side single building side engagement parts that are engaged and connected to each other. It is.

Figures 3 and 4 show conventional examples of the connection shape of the 6 engaging parts on the eave side and 1 ridge side, which are generally adopted for horizontal roofing boards made of long metal steel plates like this one. , and the effects of wind and rain pressure on the connecting and engaging portions are shown in Figures 5(a) and 5(b).
).

FIG. 3 is a cross-sectional perspective view showing a horizontally-stitched roof board according to the conventional example, and FIG. 4 is an enlarged cross-sectional view showing a state in which the eaves side one building side retaining part is connected by the same horizontally ruled roof board.

In the conventional example shown in Figures 3 and 4, the horizontal roofing board (1) is made of a long metal steel plate of a predetermined width that has been painted for rust prevention, and this metal steel plate is processed by a roll forming machine or the like. , leaving the face plate part (2) in the center along the longitudinal direction, the eave side molding part (3) on the - side side, and the ridge side molding part (3) on the other side side.
4) are each continuously molded.

Therefore, the eave side molded part (3) includes the face plate part (2).
Bend the top part (5) slightly diagonally outward and downward at a predetermined length from the side side of the head, and then lower the falling part (6) that extends downward from the tip of the crown part (5). (7)
is bent inward in an upward arc to form a folded part (8), and this folded end is formed into an edge bending part (9).

In addition, the ridge-side molding part (0) has a holding part (!0) diagonally inwardly and upwardly so as to be able to hold the edge bending part (9) from the other side of the face plate part (2). Further, a protruding piece (11) is raised upward from the tip, and the protruding edge (12) is made to protrude inwardly and downwardly.

In this conventional example, wood wool boards (14) are placed on the rafters (13) and used as back-up materials in the inner space of the horizontal roof board (1), which is on the eaves side, in this case, the front side. Then, attach it to the ridge side molded part (4) of the horizontally ruled roof board (1) of the front equipment.

Eave side molding part (3) of the next horizontal ruled roof board (1) on the ridge side
This engagement assembly is sequentially reversed from the eave side to the ridge side, that is, from the bottom to the top, to raise the desired horizontal roof.

That is, more specifically, as shown in FIG. 4, the front ridge side molded part (4) is fitted with the next eave side molded part (3), and folded back into the holding part (10). While inserting and engaging the edge bending part (9) including a part of the part (8), the falling gl
! The inner surface of (6) is brought into contact with the protruding edge (12), and in this engaged and connected state, the edge bent portion (9) is held within the holding portion (lO) and is erected. The lower edge (7) of the descending portion (6) is in line contact with the surface of the face plate portion (2), and the upward curvature of the folded portion (8) creates the first reduced pressure space (1).
5), a second decompression space (1B) in the holding part (10)
, the falling part (8) and the protruding piece part (11), the protruding edge (1
2) A third decompression space (17) is formed at each angle.

That is, as is clear from this configuration, the basic concept of the conventional engagement connection structure with the six engagement parts on the two eaves sides is as follows.
The ridge side molding part (4) is raised from the front side face plate part (2), while the eave side molding part (4) is raised from the next stage side face plate part (2).
3), an engaging abutting portion (18) exposed to the outside thereof;
By fitting and engaging connection so that it is in line contact with the surface of the flush plate part (2), it is possible to prevent rainwater from entering from the engagement surface and to prevent rainwater from entering each decompression space. Efforts are being made to reduce the infiltration pressure.

[Problem that the invention seeks to solve]

Therefore, in such a conventional horizontal roof structure made of long metal steel plates, as described above, the engaging butt portions (1) of the eave side 1 ridge side 6 engaging portions (3) and (4) 2) exists between the inner corners that touch the surface of the face plate (2) and rise at right angles to ζ. Therefore, in the case of strong wind and rain, for example, as shown by the arrow in Fig. 4, wind and rain blowing up along the roof slope of this face plate (2) will naturally cause the exposed inner corners to become damaged. The wind and rain pressure concentrated in the vicinity of the abutting part (18) and bounced upward along the falling part (6).

Examining the influence of the wind and rain pressure on the engagement abutting portion (18) at this time, we found that the wind and rain pressure (19 ), the wind pressure (20) that jumps upward, and the composite pressure (21) that is the sum of the six pressures.

Therefore, in this case, on the one hand, tj, as a simple conceivable effect, depending on the wind and rain pressure (19), water intrusion from the engagement abutment part (18) into the interior of the roof due to capillary action in the state shown in Fig. 5(d). I'm used to it. For this reason, conventionally, in the engaging butting part (18), it is necessary to avoid this capillary phenomenon as much as possible, and also to absorb errors in molding accuracy to facilitate assembly. From above, in general, surface contact at this point is avoided and the line contact structure described above is adopted, but on the other hand, depending on wind and rain pressure (20) and combined pressure (21), , falling part (6
) is lifted upward, and the engagement butt n
There is a disadvantage that (18) is pushed open and the gap between the protrusions and S becomes larger, further increasing the risk of water intrusion into the interior.

In addition, the strong wind and rain that blows concentratedly on the above-mentioned engagement abutment part (18) is usually accompanied by sand, mud, 2m of dust, etc., and these along with the rainwater are also blown inside the roof. In addition to causing corrosion inside the structure and later flowing out and staining the face plate (2) and even the roof surface, especially in cold regions, rainwater and snowflakes that have entered may freeze and expand, causing damage to the engaging surface. There were problems such as the gap being made even larger than that of the previous one.

Therefore, it is an object of the present invention to effectively prevent wind and rain, as well as the intrusion of sand, mud, dust, etc., at the retaining butt portion exposed to the outside at the six engaging portions on the eave side and one building side. It is an object of the present invention to provide a horizontal roof board having an engaging part shape that can absorb errors in molding accuracy and be easily assembled.

[Means for solving problems]

In order to achieve the above object, the horizontal roofing board according to the present invention includes a face plate part at the center in the longitudinal direction of a long metal steel plate, an eaves side molded part hanging down on one side of this face plate part, and an eave side molded part on the other side. In the horizontal roofing plate, each of which has an upright ridge side molded part, and which 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 side molding part includes a falling part that hangs down from the face plate part, a lower side part that is bent laterally inward from the folded edge of the lower end of the falling part, an inner rising part that stands up from the lower side, and an inner rising part that stands up from the lower side. and an engaging protrusion that is bent laterally inward from the part and whose end edge is folded back to the lower side,
Further, the ridge side molded part includes a rising part rising from the face plate part, an upper side part that is bent laterally outward from the folded edge of the upper end of the rising part and making line contact with the lower side part, and an upper side part an outer standing portion that is raised up from the outside and faces the inner standing portion; and an engaging holding portion that is folded back and bent laterally outward from the outer standing portion to receive the engaging protrusion in surface contact. It is something that

[Effect]

That is, in this invention, the folded edges of the rising part of the molded part on the first ridge side and the falling part of the molded part on the eave side are exposed to the outside at a position rising from the first plate part, and the butt lines are aligned with each other. Since the connection and engagement are made by contact, it is possible to avoid wind and rain from being concentrated on this engagement abutment part, and the upper and lower sides that are folded from each folded edge can be In addition, the inner standing portion and the outer standing portion that are connected to both of these portions are made to face each other in the vertical direction, and the engaging protrusion is connected and engaged with the engaging holding portion in a state of surface contact, so that the engaging In addition to the engagement action at a position raised from the face plate part of the abutting part, connection by surface contact between the engaging parts can be performed without any disadvantages. Effectively prevents water infiltration as well as intrusion of sand, mud, dust, etc., and also satisfactorily absorbs errors in molding accuracy of each engaging part, allowing for accurate and easy assembly and connection of the engaging parts. It can be done.

〔Example〕

Hereinafter, one embodiment of the horizontal roof panel according to the present invention will be explained.
This will be explained in detail with reference to FIGS. 1 and 2.

In the configurations of the embodiments shown in FIGS. 1 and 2, the horizontal roof plate (31) is, for example, a long metal steel plate of a predetermined width that has been painted for rust prevention, as in the conventional configuration. Using a roll forming machine or the like, this metal steel plate is left with a face plate part (32) in the center along the longitudinal direction, and an eave side molded part (33) is formed on the negative side and a ridge is formed on the other side. Side molding part (34)
are formed one after the other.

Therefore, the eave side molded part (33) has the face plate part (
From the side of 32), bend the crown part (35) slightly diagonally outward and downward to a predetermined length, and then lower the falling part (36) below the tip of the crown part (35). The folded edge (37) is bent in the horizontal direction to form a lower side (3 days), and from this lower side (38), an inner standing portion (38) that is slightly tilted backward is raised vertically. Further, an engaging protrusion (40) is formed by bending the inner raised part (39) inward in the lateral direction and having an edge bent (41) in a U-shape with the end facing downward.

Further, in the ridge side molded part (30), a rising part (42) which is continuous to the falling part (3B) in a shape is raised from the other side of the face plate part (32), and the upper end thereof The folded edge (43) is bent laterally outward to form an upper side (44) that is in contact with the lower side (38), and vertically extends from the upper side (44). Then, the outer standing portion (45) facing the inner standing portion (39) is raised by tilting backwards, and then the engaging protrusion (40) is moved laterally outward from the outer standing portion (45). The engaging holding part (46) that receives the parts in surface contact is folded back and a partitioning protrusion (47) that distances the internal space is formed in a curved manner at the end thereof.

Although not shown in the drawings, in order to assemble the horizontal roof panels (31) according to this embodiment into a roof structure, the first step is to assemble the front horizontal curtains on the eaves side, which are on the rafters, as in the conventional example. With the wooden roof board (31) arranged with wood wool board as a back-up material in the inner space,
Attach with hangers etc.

Next, the ridge side molding part (3) of the front horizontal curtain roof board (31)
4), by engaging the eave side molded part (33) of the next horizontal ruled roof board (31) on the ridge side, those rising parts (42) and falling parts (36) The folded edges (43) and (37) are arranged in a series in the vertical direction, and the inner parts of the respective folded edges (43) and (37) are butted against each other in a line contact state, and the upper side part (44)
The bottom part (3B).

The outer upright portion (45) and the inner upright portion (33) are opposed to each other, and the engagement protrusion (40) including the bent edge portion (41) is in close surface contact with the engagement holding portion (46). It is accepted and connected.

The roof is completed by sequentially building the roof from the eave side to the ridge side, that is, from the bottom to the top.

In this assembled state, the upper side (44) and the lower side when the engaging protrusion (40) is tightly received in the engaging holding part (46) in a surface contact state. Department (38)
Errors in molding accuracy can be absorbed by line contact between these opposing parts.

That is, in the case of this embodiment configuration, each of the horizontal roof panels (31) on the front eaves side and the rear 9 building sides that are engaged and connected to each other has a series of rising portions (42) and falling portions. (3B)
The engagement butt portion (4th day) does not exist at the corner of the inner corner that stands up in contact with the face plate portion (32) as in the conventional example, but rather Place it on the middle part rising from the part (32).

Also, this part is exposed to water due to line contact! Since E is connected, the engagement abutting portion (4
Rainwater that tries to enter from the line (B) is stopped at the line contact point (B).

Further, rainwater that has entered the interior (E) beyond the line contact point (B) due to capillary action as shown by the arrow is returned by surface contact between the holding portion (46) and the retaining projection (40).

For this purpose, 6 engaging parts (33) on the eave side and 1 building side.

The influence of wind and rain on the engagement abutment part (4th day) of (34) has been sufficiently alleviated, and rainwater has flooded from the engagement abutment part (46), as well as sand due to the wind and rain.

It is possible to effectively eliminate the intrusion of mud and dust by 1 m, and even if the intrusion occurs between the upper side (44) and the lower side (3 days) extending laterally from this engagement abutment part (48),
Since this is an intrusion without pressure and the internal space is closed due to line contact, the external standing portion (45) that extends vertically must eliminate the air that exists inside in advance.
, there is little possibility that water will reach between the inner upright parts (39), and furthermore, the engagement connection by surface contact of the retaining protrusion (40) to the engagement holding part (4B) further prevents water from entering. In addition, since wind and rain are always concentrated at the base of the t-up section (42), there is no accumulation of sand, mud, dust, etc. at the base of the t-up section (42), and even after the wind and rain have stopped. ,sand,
It is possible to prevent dirt, dust, etc. from flowing out, and not only stains on the roof surface, but also corrosion and the like can be reliably and effectively prevented.

It is also resistant to snow, and therefore can prevent the so-called dusting phenomenon.

〔Effect of the invention〕

As described in detail above, according to the present invention, the face plate part is located at the longitudinal center of the long metal steel plate, the eave side forming part is lowered down on one side of the face plate part, and the ridge side is raised up on the other side. In a horizontal roof board, each of which has a molded part, and the ridge side molded part on the previous stage is connected to the eave side molded part on the next stage to form a horizontal roof, The folded edges of the rising part of the ridge side molding part and the falling part of the eave side molding part are exposed to the outside and butted and connected to each other at a position above the face plate part. By doing so, it is possible to substantially avoid wind and rain from concentrating on this engagement abutting part, and also to prevent the upper and lower sides bent from each folded edge from being bent at one point in the lateral direction. After making line contact and vertically opposing the inner and outer standing parts connected to both of these parts, the engaging protrusion is again connected and engaged with the engaging holding part in a surface contact state. Because of this, it is possible to engage the retaining abutting part at a position rising from the face plate part, and also to connect the engaging parts by surface contact with each other without any disadvantage.
These prevent rainwater from seeping through the butts, as well as sand and mud.

It can effectively prevent the intrusion of dust, etc., and also sand, mud, etc. that tend to accumulate in these corners! Since dust can be constantly washed away, it is possible to reliably prevent the progression of corrosion and dirt caused by the accumulation of dust, and it is also possible to absorb errors in the molding accuracy of each engaging part. It has excellent features such as being able to assemble and engage the engaging parts with each other accurately and easily, being structurally very easy to rotate, and being available at the same price as the conventional one.
