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,
A predetermined engagement portion on one eave side and one ridge side for mutual engagement is formed and shaped in advance to form a horizontal roof plate, and a plurality of horizontal roof plates are attached to the front eave side and the next ridge side. This invention relates to a joint structure of horizontal roofs that are connected to each other and roofed together, and in particular to an improvement in the shape of each engaging part between the nine eaves sides.

[Conventional technology]

Conventionally, this kind of horizontal roofing type roof board made of long metal steel plates has been formed with the eave side 1 building side 6 retaining part formed,
A large number of various types and configurations have been proposed, among which combinations are mainly intended for rain closure, that is, for preventing infiltration of rainwater etc. from each engagement part of the nine eaves sides that are mutually engaged and connected. The shape of the engaging part is being actively developed.

For this reason, in the case of horizontal roof panels made of long metal steel plates, the conventional structure of each of the connection shapes at the six engaging portions on the eave side and the ridge side, which are generally adopted, was compared to the fourth example. Figure (a),
(b) and shown in FIG.

That is, FIG. 4(a) is a cross-sectional perspective view showing a horizontal roof plate according to the first conventional configuration, and FIG. 4(b) is a 6-retaining portion on the eave side and one building side of the same divided roof plate as above. FIG. 5 is an enlarged cross-sectional view showing the connection and engagement state of each of the nine eave-side and nine-building side engagement parts 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).
) from the - side side, bend the crown part (5) diagonally outward and downward to a predetermined length, and let the falling part (6) fall downward from the tip, 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 (lO) is bent diagonally inward and upward so that the bent edge part (9) can be held from the other side, and
A protruding piece (11) is made to stand up above the protruding end, and its protruding edge (12) is made to protrude inwardly and downwardly.

In this first conventional configuration, first, the horizontal roofing board (13), which is on the rafter (13) or the roofing board surface as the part to be thatched, 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, In contrast to the ridge side molded part (4) of the previous horizontal ruled roof board (1), the next horizontal ruled roof board (1) on the ridge side
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 is achieved. You get it.

That is, more specifically, as shown in FIG.
), insert and engage the edge bending part (9) including a part of the folded part (8) into the holding part (lO), and also insert the inner surface of the falling part (6) into engagement. In this engagement and connection state, the edge bending part (9) is held in the holding part (lO) and the folded part (8) is curved upward. The first decompression space (1
5) is formed, a second decompression space (16) is formed within the holding part (10), and a falling part (6), a protruding piece part (11), and a protruding edge (12) are formed. A third decompression space (17) is formed therein.

Next, in the case of @'s second conventional example, regarding the first eave side molded part (3), the crown part (5) and the falling part (
6), 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 (20
), and furthermore, this is attached to the inside by extending the seat (21), and also in this second conventional configuration, the holding part (lO) includes the edge bending part (19). While inserting and engaging the folded portion (18), the falling portion (6)
) is brought into contact with the tip of the folded part (19), and in this connected state, a first decompression space (22) is formed within the holding part (10), and the inner surface of the folded part (19) is A second reduced pressure space (23) is formed in the upper interior.

In other words, the first of these. As is clear from the configurations of the second conventional examples, the basic concept of the conventional connection structure in the 6 engagement parts on the 1 ridge side of the eaves is that the ridge side raised from the front face plate part (2) Compared to the molding part (0), the face plate part (2) on the next stage side
), the eaves side molded part (3) is fitted and engaged so that the externally exposed retaining abutment part 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 structure of horizontal roofs made of long metal steel plates in each of the conventional examples configured as described above, the engagement abutment part of the six engagement parts on the first eaves side is the same as that of the first plate part. The engaging abutting portion is located at a corner of an internal corner F that is perpendicular to the same surface plate portion, and therefore has a strength of 1. In times of wind and rain, for example, as shown by the arrow in Figure 4(b),
Naturally, the wind and rain blown up along the roof slope given to the face plate section will be concentrated on the engaging abutment section exposed at the corner of the inner corner section. In particular, strong wind and rain pressure is applied to this engaging butt part, and water ingress pressure based on capillary phenomenon at the engaging butt part is greatly increased, and in this case,
The wind and rain pressure from below on the falling part following this engagement abutment part also pushes the engagement abutment part open, causing the gap between the engagement abutment part and the face plate surface to increase. There is a disadvantage that the gap tends to become larger, further increasing the risk of water intrusion into the interior of the six engaging portions on the eave side and one building side that are engaged and connected to each other.

Furthermore, the strong wind and rain that concentrates on the above-mentioned butt joints generally produces sand and mud.

It is often accompanied by dust, and there is a risk that this will enter the roof along with rainwater, causing problems such as spring and fall due to the iron contained in the sand, and that this will later flow out and stain the face plate surface and eventually the roof surface. In addition, especially in cold regions, rainwater and snowflakes that have entered can freeze and expand, making the gap between the retaining surfaces even larger, increasing the chances of rainwater infiltrating. It was something that I had.

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 engagement abutting portions exposed to the outside at each of the above-mentioned nine eave-side engagement portions. It also has an engaging part shape that effectively prevents 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 molding part on one side of this face plate part, and the like. It has a horizontal roof board with a ridge side molded part formed on the side, and the eave side molded part of the blow-in side horizontally ruled roof board is mutually engaged with the ridge side molded part of the front side horizontally ruled roof board. A joint structure of horizontal roofs connected to each other, wherein the eave side molded part has a falling part to form a lower folded edge, and the lower folded edge is folded inward to form an edge. The folded part has an edge bent part at the part thereof, and the ridge side molded part has at least one first step rising part raised from the face plate part, and from the flat surface part of the first step rising part, Raise a second stage rising portion that connects the falling portions as flush as possible to form an upper folded edge that abuts the lower folded edge;
Further, the upper folded edge is bent outward to form a receiving part that receives the folded part including the bent edge part, and further a receiving holding part is formed by folding back to cover the folded part from this receiving part. It is a feature.

[For production]

That is, in the joint structure of a roof using horizontal roof sheets according to the present invention, the eave side molding of the horizontal roof sheet on the next stage ridge side is compared to the ridge side molding part of the horizontal roof sheet on the previous stage eave side. The upper folded edge of the rising part is engaged with the lower folded edge of the falling part, and the folded part including the edge bending part is received in the receiving part. The abutting joints of the upper and lower folded edges of the part and the falling part are located at the part rising from the face plate part via the t51 step rising part and the second step rising part, and are located along the face plate part. The wind and rain blown up by the wind and rain are first dissipated by the rising part of the first stage, and then pass through the flat surface part and hit the rising part of the second stage, so the force is sufficiently weakened, and in this state. Since the wind and rain will pass through the butt joint, the wind and rain will not be directly exposed to the butt joint, and at the same time, the rising and falling parts will be flush with each other as much as possible to prevent the wind and rain from blowing against the butt joint. In addition, a decompression space is formed by the folded part inside the butt joint, and the intrusion pressure of rainwater can be effectively reduced.

〔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 3.

Fig. 1 is a cross-sectional perspective view showing the horizontal roof board according to the first embodiment, and Fig. 2 is an enlarged cross-sectional view showing the connected and engaged state of the horizontal roof board at each joint on the eave side and 9 building sides. It is a diagram.

That is, in the configuration of the first embodiment shown in FIGS. 1 and 2, the horizontal roofing board (31) is coated with a coating or the like for anticorrosive baking, as in the case of the conventional configuration. A long metal steel plate with a predetermined width is used, and a face plate portion (32
), and the eave side molding part (33) on the negative side side and the ridge side molding part (30) on the other side side are formed continuously, and this is formed into a predetermined unit length. Cut it in half,
Although not shown, usually one of the cut ends has a folded connection part to the surface side for longitudinal connection.
On the other side, a folded connection portion to the back side is formed respectively.

Therefore, the eave side molded part (33) has the face plate part (
From the side of 32), bend one crown part (35) slightly diagonally outward and downward to a predetermined length, and also let a falling part (3B) fall downward from the tip, Fold the lower folded edge (37) inward and fold the folded part (3B)
), and the folded end is bent upward to form a bent part (39).

Subsequently, the ridge side molded part (34) has the face plate part (3
2) Raise the first raised part (40a) from the other side, and further raise the second raised part (40c) from the upper flat surface part (40b). The upper folded edge (41) is folded outward to form a receiving part (42) for receiving the folded part (38) including said folded part (39), and also this receiving part (4
2), fold the receiving and holding part (43) upwardly inside so as to cover this, and the receiving and holding part (43)
is folded back and bent down to a position corresponding to the face plate surface, and a mounting portion (44) for fixing is formed.

In the case of this first embodiment configuration, in order to assemble each horizontal roof board (31) into a roof structure, as in the case of the conventional configuration, the rafters (1
3) Or on the field board surface.

First, install the horizontal roof shingles (3
1), with a wood wool board (14) as a back-up material placed in the inner space of the part (44).
) as is well known, attach it with pegs (not shown), and then attach this front horizontal ruled line jffiffl.
For the ridge-side molded part (34) of the board (31), the eave-side molded part (33) of the next horizontal roof board (31) on the ridge side is attached to the rising part (40c) of the eave-side molded part (33). (3B) are arranged in a series and each folded edge (41), (3?) is butted to form a butt joint (48), and the folded edge including the edge bent part (39) Department (38)
are received by the receiving part (42), held in the receiving and holding part (43), and engaged and connected, and this engaged connection is made sequentially from the eave side to the ridge side, that is, from the bottom to the top. The roof is then raised to obtain the desired horizontal roof structure.

In the horizontal roof structure assembled in this way, the upper part of the rising part (40a) and the falling part (3G),
The butt joints (4G) of the lower folded edges (41), (37) are substantially located on the surface portions rising from the face plate portion (32), and these second-stage rising portions (
40C) and the falling part (36) are connected to each other so as to be flush with each other as much as possible, and inside the engaging part, inside the folded part (38), there is a first decompression space part. (45
a) and the second decompression space (45b) are constructed in sequence.

In this case, in the case of the oval configuration of the first embodiment, in each horizontally ruled roof board (31) of the front stage of the eaves side and the next stage of the nine building sides that are engaged and connected to the phase π, there is a As is clear from Fig. 2, the first stage rising part (40a) is the directly relevant pressure surface for the wind and rain blown up along the line, and then the second stage rising part (40C) is the indirect relevant aspect. In this case, the overall rising height of the eave side 1 building side sections (33) and (34) that are interconnected and connected to each other is essentially the same as that of the first stage and the first stage, which are a series. The heights of the rising parts (40a) and (40c) of the two stages and the falling part (38) are equal, and the joint part of both of them exposed to the outside is one indirect corresponding surface. The upper folded edge (41
) and the lower folded edge (3) at the falling part (36).
7), and this engaging butt portion (46) is in direct contact with the surface of the face plate portion (32) as in the case of the conventional configuration described above. The inner corner does not exist at the corner of the internal corner rising at a right angle, but is located flush with the middle part of the vertical and burr pressure receiving surface on the plane of the flat surface part (40b).

Therefore, in the configuration according to the first embodiment, the face plate portion (32
), the wind and rain blown up along the C-line (32) will inevitably be concentrated at the corner of the inner corner that rises at right angle C from the same plane plate (32), as described above in the conventional configuration. However, in this case, as is clear from Fig. 2, the part corresponding to the same angle corresponds to the base of the first stage rising part (40a) of the ridge side engaging part (34). The wind and rain that concentrates on the base of the first stage rising part (40a) is caused by the fact that there is no matching butt part at the base.
The blow hits the first stage rising part (40a), and after the force is sufficiently weakened, it rebounds upward and flows,
It flows in the longitudinal direction along the base of this first stage rising part (40a), and a part of the weakened wind and rain, as well as the face plate part (3
2) Wind and rain that simply blows onto the surface of the flat surface portion (40b), that is, wind and rain that is weak in force, is again blown onto the second stage rising portion (40c) and acts in the same way. This abutment part (46) that engages the wind and rain
In this way, the eave side 9 ridge side 6 engaging parts (33),
The influence of wind and rain blown up along the first plate part (32) is sufficiently alleviated on the engagement butt part (46) of (34).

In other words, the first stage rising portion (roa
) without the engaging abutting portion (48) present.

An abutting portion (46) engages with a portion raised from the second stage rising portion (40c) via the first stage rising portion (40a).
is formed, and since the second stage rising part (40c) and the falling part (36) are connected in a plane and are flush with each other, the first stage rising part (40a) is blown. Once the wind and rain were hit and de-energized, the wind and rain hit each other.
(48) and flows upwardly, therefore, the falling part (
38) is not given an upward pushing-opening action, and at the same time flows in the longitudinal direction along the base where the engagement abutment part (46) does not exist, so that the engagement abutment full (4B)
This effectively eliminates wind and rain as well as the infiltration of sand, mud, dust, etc. that accompany these wind and rain.

In addition, the base of the first stage rising portion (40a) is of course
Because the wind and rain that are constantly blown on the base of the second stage rising section (40C) concentrate and flow, it is unlikely that sand, mud, dust, etc. will accumulate at the base of each base. There is no possibility that sand, mud, IN dust, etc. will flow out after settling, and therefore the roof surface can be well prevented from getting dirty. Even if some rainwater enters due to capillary action, this small amount of rainwater is absorbed by the first decompression space (45a) that is continuous inside the retaining abutment (46). The intrusion pressure is sufficiently reduced and relaxed, and together with the existence of the second decompression space (45b), the intrusion does not penetrate further into the interior.

Furthermore, the engagement mode of the two eaves-side ridge-side six engaging parts (F3) and (34), in other words, in the joint structure according to this embodiment, the falling part ( 36
) is folded inward to form a folded part (38), so this folded part (38
) is given sufficient elasticity, and due to this given elasticity, the second part of the ridge side engaging part (34)
The contact pressure of the lower folded edge (37) of the falling part (3B) against the upper folded edge (41) of the step rising part (40c) can be continuously and reliably maintained, and the It can sufficiently absorb the expansion and contraction of the horizontal roof board (31) in the width direction, and furthermore, the folded edge portion (38), which is formed by bending the folded end of the folded portion (38) upward, is attached to the receiving portion (42). It can be received easily and firmly, and there is no tendency for the horizontal roofing sheets (31) to peel off or otherwise occur, and a good engagement state can be maintained for a long period of time. .

Next, FIG. 3 shows a configuration of a second embodiment as a modification of the configuration of the first embodiment described above.

That is, in the configuration of the second embodiment, the folded portion (3 days) and the receiving portion (42) that are pressed against each other form step portions (38a) and (42a) in the C intermediate portion. At the same time, a chevron-shaped part (43a) is formed on the receiving and holding part (43), and the mounting part (44) is omitted. In addition to obtaining similar functions and effects, it is possible to more effectively reduce the pressure of rainwater entering due to the capillary phenomenon described above.

In each of the embodiments described above, the bending direction of the edge bending portion (39) is toward the lower side, but even if this direction is bent toward the lower side, the same operation and effect as described above can be obtained.

〔Effect of the invention〕

As described in detail above, according to the present invention, the face plate part is provided at the center in the longitudinal direction, and the eave side molded part is provided at one side of the face plate part.
It has a horizontal roof plate with a ridge molding formed on the other side,
In a horizontal roof joint structure in which the ridge side molding of the previous horizontal ruled roof board is connected to the eave side molding of the next horizontal ruled roof board, the eave side molding The lower folded edge of the bracket is folded down to form a lower folded edge, and the lower folded edge of the bracket is folded inward to form a folded part with a bent edge at the end. One first stage rising part is raised, and a second stage rising part is raised from the flat surface part of this first stage rising part to connect the falling parts as flush as possible to form an upper folded edge. In addition, this upper folded edge is bent outward to form a receiving part, and a receiving holding part is further folded back to cover the folded part from this receiving part, so that the horizontal roof board on the front eave side can be used. The eave side molding part of the horizontal roof board on the next ridge side is fitted onto the ridge side molding part fixed with hangers etc., and the upper folded edge of the rising part is fitted with the lower folded edge of the falling part. By a simple operation of butting them together and receiving the folded part including the bent edge part into the receiving part, these two parts can be engaged and connected to form the desired horizontal roof structure, and In the horizontal roof structure configured in this way, the butt joints at the folded edges of the upper and lower parts are located at the part rising from the face plate part through the first and second rising parts. The wind and rain that is blown up along the face plate is first dissipated by the first stage rising part, and then passes through the flat surface part and hits the second stage rising part, so that its force is sufficient. In this state, the butt joint is weakened by the wind and rain, and the wind and rain from the butt joint are not directly blown onto the butt joint. Sand, mud + J! Infiltration of JI dust, etc. can be effectively and proactively eliminated, and at the same time, the rising and falling parts of these parts are made as flush as possible, so that wind and rain can be appropriately dissipated, and these It is possible to prevent the accumulation of sand, mud, dust, etc., as well as the progress of corrosion and dirt caused by the accumulation.Furthermore, a depressurized space is formed by the receiving and holding part inside the butt joint. In order to effectively reduce the infiltration pressure of rainwater and effectively prevent rainwater from infiltrating further into the interior, the rising and falling parts that abut each other have sufficient pressure resistance. It is resistant to snow loads.

This also prevents leaks, which are common in cold regions.

In addition, in the engagement mode at these 6 engagement parts on the eave side and 1 building side,
Since the folded part is formed by folding back from the lower folded edge of the falling part in the eaves side engaging part, and this folded part is held in contact with the receiving part and held by the receiving and holding part,
Sufficient elasticity is given to this folded part, and this given elasticity ensures that the contact force of the lower folded edge at the eave side engagement part against the upper folded edge at the ridge side engagement part is maintained continuously and reliably. At the same time, it becomes easy to form a depressurized space inside the folded part, and the ridge side engaging part has elasticity. Due to the existence of the ν section, it is possible to form an expansion/contraction absorbing section that also serves as a decompression space, and to attach horizontal roofing boards by attaching hangers, etc. to the holding section. Therefore, the expansion and contraction in the width direction of each horizontal ridge board due to the difference in outside temperature can be sufficiently absorbed by this receiving and holding part, and the eave side 9 building side 6
The engagement mode of the engagement part can be maintained for a long period of time, and the overall structure itself can be formed simply by forming the side part of the metal steel plate, making manufacturing extremely easy and no different from conventional methods. It has excellent features such as being available at a reasonable price.
