Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a joint structure of a roof using horizontal roofing sheets made of metal steel sheets, and more specifically, the rust-preventing baking is performed by painting or the like. At both ends of the long metal steel plate according to the specified width,
Predetermined eave-side two ridge-side retaining parts for mutual engagement are formed in advance on each side to form a horizontal roof plate, and a plurality of these horizontal roof plates are attached to the front eave side and the next ridge side. The present invention relates to a joint structure of horizontal roofs that are raised by engaging and connecting with each other, and in particular to improvements in the shapes of the mutually engaging parts between the eaves and one building side.

[Conventional technology]

Conventionally, this kind of horizontal roofing type roof plate made of long metal steel plates has each engaging part on the eave side and one ridge side formed into shape.
A large number of various types and configurations have been proposed, and among them, a combination lock is mainly intended for rain closure, that is, to prevent rainwater from entering from each engagement part of the nine eaves sides that are mutually and securely connected. Joint shapes are being actively developed.

Therefore, in the case of such a horizontal roof board made of long metal steel plates, the conventional structure of each of the connection shapes at the eave side 9 ridge side 6 joint parts which are generally adopted is shown in the fifth example. Figure (a),
(b) and shown in FIG.

That is, FIG. 5(a) is a cross-sectional perspective view showing a horizontal roof plate according to the first conventional configuration, and FIG. 5(b) is a sectional perspective view showing the eave side 9 building side 6 retaining portion of the same divided roof plate. FIG. 6 is an enlarged cross-sectional view showing the connected and engaged state of the 9 eave side 6 engaging parts on the ridge side of the horizontal roof board according to the second conventional configuration. FIG.

In each of these conventional configurations, in the case of the first conventional example, the horizontal roofing board (1) is, for example, a long metal steel plate of a predetermined width that has been painted for rust prevention. A metal steel plate is formed using a roll forming machine or the like, leaving a face plate part (2) in the center along the longitudinal direction, and forming an eave side forming part (3) on the negative side and a ridge side forming part on the other side. (4) are formed in succession, and then cut into a predetermined unit length.Although not shown in the figure, usually one of the cut ends is connected in the longitudinal direction. A folded connection part to the front side is formed on one side, and a folded connection part to the back side is formed on the other side.

Therefore, the eave side molded part (3) has the face plate part (2).
), bend the crown part (5) slightly diagonally outward and downward to a predetermined length, and let the falling part (6) fall downward from the tip of the crown part (5), and The lower edge (7) is folded inward in an upward arc to form a folded part (8).
and this folded end is formed into an edge bending part (9).

Subsequently, the ridge side molded part (4) has the face plate part (2).
The holding part (10) is bent diagonally inward and upward so that the bent edge part (9) can be held from the other side, and
After making the protruding piece (11) stand up above the protruding end, (12) is made to protrude inwardly and downwardly.

In this first conventional configuration, first, the horizontal roofing board (1), which is on the rafter (13) or the roofing board surface as the part to be roofed, is on the eaves side, in this case, the front side.
, with a wood wool board (14) as a back-up material arranged as appropriate in the inner space, and attached, for example, with a hanger member (not shown), as is well known, and then, The next horizontal roof board (1) on the first building side is attached to the ridge side molded part (4) of the previous horizontal roof board (1).
By engaging and connecting the eave side molded parts (3) as shown in the diagram, and repeating this engagement sequentially from the eave side to the ridge side, that is, from the bottom to the top, the desired horizontal roof structure can be achieved. You get it.

That is, more specifically, as shown in FIG. 5(b), the next stage side eave side molded part (3
), insert and engage the edge bending part (9) including a part of the folded part (8) into the holding part (10), and also insert the inner surface of the falling part (6) into the holding part (10). The projecting edge (12) is abutted and connected, and in this securely connected state, the edge bent portion (9) is held within the holding portion (10) and the folded portion (8) is bent upward. The first decompression space (1
5) is formed in the holding part (10), a second decompression space part (16) is formed, and a falling part (6), a protruding piece part (11), and a projecting edge (12) part are formed. A third decompression space (17) is formed therein.

Next, in the case of the latter second conventional example, regarding the first eave side molded part (3), the crown part (5) and the falling part (
8), and its lower edge (7) is folded inward to form a folded part (18), and this folded end is formed into a bent edge part (19), and the ridge side molded part ( Regarding 4), the holding part (10) is formed in the same manner as above, and the tip part is folded back to form the folded part (19).
, and a bent part (2
0), and furthermore, this is installed inside by extending the seat (21), and also in this second conventional configuration, the edge bending part (19) is attached to the holding part (lO). The folded part (18) including the folded part (18) is inserted and engaged, and the falling part (18) is inserted and engaged.
6) is butt-connected to the tip of the folded part (19), and in this connected state, a first decompression space (22) is formed within the holding part (lO), and the folded part (IS )
A second depressurized space (23) is formed inside the upper part.

In other words, the first of these. As is clear from the configurations of the second conventional examples, the basic concept of the connection structure in each of the nine eave side engagement parts is that the ridge side raised from the front face plate part (2) With respect to the molded part (4), the face plate part (
The eaves side molded part (3) raised from 2) is fitted and connected so that the engaging abutting part exposed to the outside is positioned on the surface of the face plate part (2). This is intended to prevent rainwater from entering from the engaging surfaces of the respective engaging portions, and to reduce the pressure of rainwater entering into each depressurized space.

[Problem that the invention seeks to solve]

However, in the joint structures of horizontal roofs made of long metal steel plates in the conventional examples configured as described above, the engagement abutting portions of the six engagement portions on the eave side and the first building side are the same as those of the face plate portion. The engaging abutting portion is configured to be positioned so as to directly touch the surface.

Since it necessarily exists at the corner of the internal corner that rises at a right angle C from the same plane board, in times of strong wind and rain, for example,
As shown by the arrow in FIG. 5(b), the wind and rain blown up along the roof slope given to the face plate part can be extremely violent, but the engagement exposed at the corner of the inner corner part The water will be concentrated on the abutting part, and especially strong wind and rain pressure will be applied to this engaging abutting part, and the water inundation pressure based on the capillary phenomenon at the engaging abutting part will be greatly increased. As you can see, wind and rain pressure from below on the falling part following this engaging abutting part also pushes the engaging abutting part apart, and the face plate at this engaging abutting part is pushed open. There is a disadvantage that there is a tendency for the gap between the surfaces to become larger, further increasing the risk of water intrusion into the interior of each of the nine eaves-side engaging portions that are mutually securely connected.

Furthermore, the strong wind and rain that is concentrated on the abutting portions mentioned above generally causes sand and mud.

It is often accompanied by dust, etc., and this enters the roof along with rainwater, causing red rust due to the iron contained in the sand, and later flowing out and staining the faceplate surface and eventually the roof surface. In addition, especially in cold regions, infiltrated rainwater, snowflakes, etc. freeze and expand, further increasing the gap between the engagement surfaces and increasing the chances of rainwater infiltrating. It was something.

Therefore, in view of the above-mentioned problems with the conventional device, it is an object of the present invention to protect against wind and rain at the engaging abutting portions exposed to the outside at each of the above-mentioned eave-side and one-building side engagement portions. In addition, the engaging portion has a shape that can effectively prevent the infiltration of sand, mud, dust, etc. The object of the present invention is to provide a roof joint structure using this type of horizontal roofing board.

[Means for solving problems]

In order to achieve the above object, the joint structure of a roof using horizontal roofing boards according to the present invention has a face plate part in the center in the longitudinal direction, an eave side molded part on one side of this face plate part, and an eave side molded part on the other side. It has a horizontal roof board with a ridge side molded part formed in the part thereof, and the eave side molded part of the next stage horizontal roof board is engaged and connected to the ridge side molded part of the previous stage horizontal roof board. This joint structure of a horizontal roof is constructed by forming a lower folded edge in the eave side molded part by lowering a falling part, and folding the lower folded edge inward to form a lower folded edge. The folded part has a bent edge part, and the ridge side molded part has a rising part that projects inward in an overhang shape, and a protruding part that encloses a wooden shelf space at the base of the rising part. forming an upper folded edge that abuts the lower folded edge, and folds this upper folded edge outward,
The present invention is characterized in that the folded portion including the edge bending portion is a receiving portion that receives the folded portion, and further, a folded holding portion having a downward chevron portion is formed so as to cover the folded portion from the receiving portion.

[For production]

That is, in the roof joint structure using the horizontal roofing boards according to the present invention, the ridge side molded part of the horizontal roofing board on the previous stage eave side is compared to the eave side molded part of the horizontal roofing N root board on the next stage ridge side. The molded part is fitted, and the folded part including the edge bending part is pressed against the receiving part so that the upper folded edge of the rising part and the lower folded edge of the falling part are brought into contact with the receiving part and received in the folded holding part. By making a mating connection like this, the butt joints of the upper and lower folded edges of the rising part and the falling part are located in the part rising from the face plate part, and the face plate Wind and rain blowing up along the butt joint does not directly hit the butt joint, and the rising part
Since the raised base is formed with a protruding shape that encloses the wood cutting space, the presence of the wood trellis space allows for appropriate wind and rain blowing, and the folding at the butt joint part On the inside side of the part and the receiving part, a decompression space part of 4 Pi is formed by the folded holding part including the downward chevron part, which can effectively reduce the pressure of rainwater entering through the butt joint part. Tame, horizontal ruled line! In addition to being easy to fix, the roof panels can effectively absorb the expansion and contraction of the horizontal roof panels and, by extension, the face panels due to temperature differences.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, various embodiments of a roof joint structure using horizontal roof panels according to the present invention will be described in detail with reference to FIGS. 1 to 4.

Fig. 1 is a cross-sectional perspective view showing the horizontal roof plate according to the first embodiment, and Fig. 2IA is an enlarged cross-sectional view showing the state of connection and engagement at each joint on the eaves side and the first building side of the same verified roof plate. be.

That is, in the configuration of the first embodiment shown in FIGS. 1 and 2, the 3M root plate (31) is coated with paint for anti-rust baking, as in the case of the conventional configuration. Using a long metal steel plate with a predetermined width, a face plate portion (32
), the eave side molding part (33) on the negative side side and the ridge side molding part (34) on the other side side are formed continuously, respectively, and these are formed into a predetermined unit. Although not shown, it is usually cut to length and connected in the longitudinal direction.
One of the cut ends is formed with a folded connection part to the front side, and the other cut end part is formed with a folded connection part to the back side.

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 let the falling part (36) fall downward from the tip, The lower folded edge (37) is folded inward at the y right angle to form a folded portion (38), and this folded end is bent toward the lower side to form a bent edge portion (33).

Subsequently, the ridge side molded part (34) has the face plate part (3
2) By raising the rising part (40) from the other side and making this rising part (40) protrude inward in an overhanging manner, the wooden shelf space (50) is enclosed in the rising base. In the first embodiment, a concave portion (40a) is formed, and its upper folded edge (41) is bent outward to form the edge bent portion (38).
) is used as a receiving part (42) that receives the folded part (38), and from this receiving part (42), a folded holding part (47) is formed upwardly and inwardly to cover the folded part (3B). ) is folded back to form a downward chevron portion (43), and then folded back so as to be doubled and bent down to a position corresponding to the surface of the face plate portion (32). For installation part (49)
It is formed by bending.

In the case of the configuration of this first embodiment, in order to assemble each A-roofing board (31) into a roof structure, as in the case of the conventional configuration, the rafters (1
3) Or on the roof board surface, first, on the eaves side, this
Now, with the partitioned roof board (31) on the front stage side, with the wooden wool board (14) as a back-up material arranged as appropriate in the inner space, it is installed using the stopper (49) not shown in the figure. The installation is fixed with nails, etc., and then the eave side of the next horizontal roofing board (31) on the ridge side is attached to the ridge side molded part (34) of this previous horizontal roofing board (31). Molding part (
33), the rising part (40) and the falling part (36) are continuously connected, and both folded edges (41),
(37) are butted against each other to form a butt joint (46
), and furthermore, the folded part (38) including the edge bending part (33) is received and connected inside the receiving part (42) and the folded holding part (47), This engaging connection is successively roofed from the eave side to the ridge side, that is, from the bottom to the top, to obtain the desired divided roof structure.

In the divided roof structure assembled in this way, the butt joints of the upper and lower folded edges (41) and (37) of the rising part (40) and the falling part (3B) (46) is located at the part rising from the first plate part (32), and these rising parts (40) and falling parts (3
6) are connected to each other, and the rising part (4
0), since this is made to protrude inward in an overhang shape to form a concave part (40a), a wooden shelf space part (50) is formed at the rising base of the concave part (40a).
And inside the engaging part, there is a downward chevron part (43).
The decompression space (45) is formed by the folded holding part (47).
) will be constructed.

In this case, in the case of the configuration of the first embodiment, in each of the structural roof plates (31) of the eave side front stage and the two building side next stages that are connected to each other, there is a In response to wind and rain blown up by wind and rain, the overall rising height of the 6 engaging parts (33) and 6 (34) on the 9 building sides of the eaves, which are connected and connected to each other as pressure receiving surfaces, will not change. equal to the height of a series of rising parts (40) and falling parts (36), and
The joint parts of both of these that are exposed to the outside are
This corresponds to the engagement abutment part (48) between the upper folded edge (41) at the rising part (40) and the lower folded edge (37) at the falling part (36), and this engagement butt Department (
46) does not exist at the corner of the internal corner that rises at the C right angle when it is in direct contact with the surface of the first plate part (32) as in the case of the conventional configuration described above, but the rise as a whole The pressure-receiving surface is located at the middle part of C, and the rising base of the rising portion (40) has a protruding portion that gradually overhangs in a curved shape, that is, in the case of this first embodiment, a concave portion. By the part (40a), the wooden shelf space part (50)
will exist.

Therefore, in the configuration according to the first embodiment, the first plate portion (32
), the wind and rain blown up along the ridge (32) will inevitably concentrate at the corner of the inner corner that rises at - right angles from the same plane plate (32), as described earlier in the conventional configuration. However, in this case, as is clear from Fig. 2, the part corresponding to the same angle is the rising part (4
0), and from this base, the concave part (40a) is raised and the wooden shelf space part (40a) is raised.
50), wind and rain concentrate on the base of this rising portion (40) and, by extension, on the wooden shelf space (50).

Since there is no engaging abutting part at the base, after being blown onto the base, it is directed upward along the protruding shape part, in this case the concave part (40a), and flows smoothly. , on the other hand, flows longitudinally along the base of the rising portion (40) and connects it to the engaging butt portion (40).
46), and thus the influence of wind and rain on the engaging abutting portion (46) can be sufficiently alleviated.

In other words, in the case of the configuration of this first embodiment, the rising portion (40)
There is no engaging abutting portion (46) at the base of the base, and there is a rising portion (40) and a falling portion (36).

- Since the concave part (40a) is formed in the rising part (40), wind and rain are given an upward direction by the concave part (40a). Then, the engaging abutting portion (48
) and thus easily flow upwards beyond the falling part (
36) without giving an upward force-opening action, and at the same time flowing in the longitudinal direction along the base where the engaging abutting part (4B) does not exist, wind and rain from the engaging abutting part (46), In addition, the infiltration of sand, mud, dust, etc. caused by wind and rain can be effectively eliminated.

In addition, since the wind and rain that are constantly blown on the base of the rising part (4G) concentrate and flow, sand and
There is no possibility of mud, dust, etc. accumulating, and as a result, it is completely possible for sand, mud, dust, etc. to flow out even after the wind and rain have stopped, so it is also possible to prevent the roof surface from getting dirty. , and also.

Even if some rainwater enters from the engagement abutment part (4B) due to capillary action, this small amount of rainwater will be absorbed into the depressurized space that is continuous inside the engagement abutment part (46). The intrusion pressure is sufficiently reduced and relaxed by the part (45), and henceforth, it will not infiltrate further into the interior.

Furthermore, this eave side 9 building side 6 engaging parts (33), (34
), in other words, in the joint structure according to the first embodiment, the lower folded edge (37) of the falling part (36) in the eaves side engagement part (33) is folded inward and folded back. Since the folded part (38) is in contact with the receiving part (42), it is wise to provide sufficient elasticity between these two parts. Due to its elasticity, the upper folded edge (4) of the rising portion (40) at the ridge side engaging portion (34)
