The joint structure of a horizontal roof in which the front eave side and the next ridge side are engaged and connected to each other, and in particular the shape of each formed part of the eave side and ridge side is improved. It is.

[Conventional technology]

Hitherto, many different types and configurations have been proposed for this type of horizontal roofing plate made of long metal steel plates with formed parts on the eaves and ridge sides. There has been active development of combination engagement part shapes mainly designed to prevent rainwater from entering from the molded parts on the eaves and ridge sides that are engaged and connected to each other.

Here, Fig. 5 shows a conventional example structure of each connection shape of each forming part on the eave side and ridge side, which is generally adopted in such horizontal roofing sheets made of long metal steel plates. Shown in a, b and FIG.

That is, FIG. 5a is a cross-sectional perspective view showing the horizontal roofing board having the configuration of the first conventional example, and FIG. 5b is a connected and engaged state of the molded parts on the eave side and ridge side of the same horizontal roofing board. FIG.
The figure is an enlarged cross-sectional view showing the connected and engaged state of the molded parts on the eaves side and ridge side of a horizontal roof board according to the second conventional structure.

In the configuration of each of these conventional examples, the former first
In the case of the conventional example, as shown in FIG. 5a, the horizontal roofing board 1 is made of a long metal steel plate of a predetermined width that has been coated with anti-corrosion baking paint, and this metal steel plate is processed by a roll forming machine. etc., leaving the face plate part 2 in the central part along the longitudinal direction, and forming the eave side molding part 3 on one side of the face plate part 2 and the ridge side molding part 4 on the other side of the face plate part 2 in succession. and cut it into a predetermined unit length.Although not shown in the figure, normally,
For the longitudinal connection, one of the cut ends is formed with a folded connection to the front side, and the other is formed with a folded connection to the back side.

The eave side molded part 3 has a crown part 5 bent slightly diagonally outward and downward to a predetermined length from one side of the face plate part 2, and a descending part 6 below the tip thereof. is made to fall, and its lower end edge 7 is folded back inward in an upward arc to form a folded portion 8, and this folded end is formed into an edge bent portion 9.

The ridge side molded part 4 has a holding part 10 bent diagonally inward and upward so as to be able to hold the edge bending part 9 from the other side of the face plate part 2, and has a protruding end thereof. After raising the protruding piece 11 further upward,
The projecting edge 12 is made to protrude inwardly and downwardly.

In the configuration of this first conventional example, on the rafter 13 or the roof board surface as the part to be roofed, first, the horizontal roof board 1, which is on the eaves side, here the front side, is With wooden wool boards 14 and the like as back-up materials arranged as appropriate in the inner space, for example, as is well known, it is attached using a hanger member (not shown), and then this front side horizontal roof is installed. For the ridge side molded part 4 of the plate 1,
Engage and connect the eave side molded parts 3 of the next-level horizontal roofing board 1 on the ridge side as shown in the diagram, and repeat this engagement sequentially from the eave side to the ridge side, that is, from the bottom to the top, to raise the roof. As a result, the desired horizontal roof structure is obtained.

That is, more specifically, as shown in FIG. The bent edge part 9 including a part of the edge part 8 is inserted and engaged, and the inner surface of the falling part 6 is abutted against and connected to the protruding edge 12. In this engaged and connected state, the bent edge part 9 is inserted and engaged. A first reduced pressure space 15 is formed by the upward curvature of the folded part 8 while being held within the holding part 10, and a second reduced pressure space 16 is formed within the holding part 10; A third decompression space 17 is formed between the falling portion 6, the protruding piece 11, and the protruding edge 12.

Next, in the case of the latter second conventional example, as shown in FIG. is folded inward to form a folded part 18, and this folded end is formed into an edge bending part 19, and the ridge side molded part 4 is also formed with a holding part 10 in the same manner as described above, and its folded end is formed into a bent part 19. The projecting end is folded back to form a folded part 19, and this is bent upward to form a bent part 20, which is further constructed by extending a mounting seat 21 inward.This second conventional example Also in the configuration, the folded part 18 including the edge bending part 19 is inserted into the holding part 10 and engaged, and the inner surface of the falling part 6 is abutted against the tip of the folded part 19 and connected, and this connected state A first reduced pressure space 22 is formed within the holding portion 10, and a second reduced pressure space 23 is formed inside the folded portion 19 above.

In other words, as is clear from the configurations of these first and second conventional examples, the basic concept of the connection structure in the conventional eave side and ridge side molded parts is that from the front side face plate part 2 In contrast to the ridge side molded part 4 that has been raised, the eave side molded part 3 is lowered from the face plate part 2 on the next stage side.
are fitted and connected so that the engaging abutting portions exposed to the outside are positioned on the surface of the face plate portion 2, thereby preventing infiltration of rainwater etc. from the engaging surfaces of the respective molded portions. This is intended to prevent the infiltration of rainwater and the like in 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 engaging butt portions of the molded portions on the eave side and the ridge side are aligned with the surface of the face plate portion. The engaging abutting portion is configured to be positioned so as to be in direct contact with the
Since it naturally exists at the corner of the internal corner rising almost perpendicularly from the same face plate, in times of strong wind and rain, for example, as shown by the arrow in Figure 5b, As a matter of course, wind and rain blowing up along the slope of the roof will concentrate on the engaging abutment exposed at the corner of the inner corner, and especially on this engaging abutment. Strong wind and rain pressure is applied to the mating abutting part, and water ingress pressure based on capillary phenomenon at the engaging abutting part is greatly increased, and in this case, water is applied to the falling part following this engaging abutting part. Due to wind and rain pressure from below, the engaging abutting portions are also pushed apart, and the gap between the engaging abutting portions and the face plate surface tends to increase, causing the two to engage with each other. There is a disadvantage that the risk of water infiltration into the inside of the eave side and ridge side molded parts that are connected is further increased.

Furthermore, the strong wind and rain that concentrates on the above-mentioned engagement butt portions generally causes sand, mud, etc.
Often accompanied by dust, etc., these enter the inside of the roof along with rainwater, causing red rust due to the iron contained in the sand, which later flows out and stains the face plate surface and eventually the roof surface. There is a fear,
In addition, especially in cold regions, rainwater, snowflakes, etc. that have entered may freeze and expand, further increasing the gap between the engagement surfaces and increasing the chances of rainwater entering. Ta.

Therefore, in view of the above-mentioned problems in the conventional example, it is an object of the present invention to prevent wind and rain at the engaging abutment portions exposed to the outside of the eave side and ridge side molded portions. It also has a molded part 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. In the joint structure of the horizontal roof, 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 at the end. Further, the ridge side molded part has a raised part that projects inwardly in an overhang shape, and a protruding shaped part that embraces the water drainage space is formed at the base of the raised part. forming an upper folded edge that abuts the lower folded edge, and folds the upper folded edge outward to form a receiving portion for receiving a folded portion including the edge bent portion; It is characterized by forming a folded holding part with a downward chevron-shaped part so as to cover the part.

[Effect]

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. so that the upper folded edge of the rising part and the lower folded edge of the falling part are butted together, and the folded part including the edge bending part is pressed against the receiving part and received in the folded holding part. By engaging and connecting the rising part and the falling part, 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, so that the joint parts are located along the face plate part. Wind and rain blown up by the wind and rain do not directly hit this butt joint, and since the rising part has a protruding part that encloses a water drainage space at the base of the rising part, the wind and rain blown against it can be appropriately disposed of by the existence of the water drainage space, and on the inside side of the folded part and the receiving part at the butt joint part, the folded holding part including the downward chevron part allows the decompression space to be separated. is configured to effectively reduce the pressure of rainwater entering through the butt joint, making it easier to install and fix the horizontal roof panels, and also reducing temperature differences between the horizontal roof panels and the face plate. It can effectively absorb the expansion and contraction due to

〔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 roofing board according to the first embodiment, and FIG. 2 is a cross-sectional view showing an enlarged connection and engagement state at the eaves side and ridge side engaging parts of the horizontal roofing board according to the first embodiment. It is a diagram.

That is, in the first embodiment shown in FIGS. 1 and 2, the horizontal roofing board 31 is a long sheet of a predetermined width, which is coated with anti-rust baking coating, etc., as in the conventional example. Using a metal steel plate, this metal steel plate is formed by a roll forming machine or the like, leaving a face plate part 32 in the center along the longitudinal direction, and forming an eave side forming part 33 on one side of the face plate part 32 and a ridge side forming part on the other side. Each of the molded parts 34 is continuously formed and shaped, and is cut into a predetermined unit length.Although not shown in the drawings, normally, one of the cut ends is cut in order to connect in the length direction. Forms a folded connection part to the front side, and a folded connection part to the back side on the other side.

In the eave side molded part 33, a crown part 35 is bent slightly diagonally outward and downward to a predetermined length from one side of the face plate part 32, and a falling part 36 is formed below the tip of the head part 35. The lower part of the folded edge 37 is folded inward at a substantially right angle to form a folded part 38, and this folded end is bent downward to form a bent part 39.

In the ridge side molded part 34, a rising part 40 is raised from the other side of the face plate part 32, and this rising part 40 is made to protrude inwardly in an overhang shape, thereby creating a water drainage space at the rising base. In this first embodiment, a concave portion 40a is formed, and the folded edge 41 at the top thereof is bent outward to receive the folded portion 38 including the edge bent portion 39. 42, and from this receiving part 42, a folded holding part 47 is folded upward and inward so as to cover the folded part 38 to form a downward chevron part 43, and then this is folded back into two parts. It is folded back so as to overlap and bent down to a position corresponding to the surface of the face plate portion 32, and a mounting portion 49 for mounting and fixing is formed by bending.

In the case of this first embodiment, in order to assemble each horizontal roof board 31 into a roof structure, as in the case of the conventional example, the steps are to assemble the horizontal roof boards 31 on the rafters 13 or the roof board surface as the part to be roofed. First, the horizontal roof shingles 31, which will be the eaves side, here the front side.
, with a wooden wool board 14 or the like as a back-up material appropriately arranged in the inner space, and the mounting part 4 is installed.
9 is attached and fixed with pegs (not shown), and then this front side horizontal roof board 31 is attached.
The eave side molded part 33 of the next horizontal roof board 31 on the ridge side is
The folded portion 38 including the edge bent portion 39 is arranged so that the falling portions 36 of the folded portion 36 are connected continuously, and the respective folded edges 41 and 37 are abutted against each other to form a butted joint portion 46. , the receiving part 42 and the folded holding part 47 are received inside and engaged and connected, and this engaged connection is sequentially roofed from the eave side to the ridge side, that is, from the bottom to the top, to achieve the desired horizontal roofing. You get the roof structure.

In the horizontal roof structure assembled as described above, the butt joint 4 of the upper and lower folded edges 41 and 37 of the rising part 40 and the falling part 36
6 is located at a portion rising from the face plate portion 32, and the rising portion 40 and the falling portion 36 are connected to each other, and the rising portion 40
Since the concave portion 40a is formed by protruding inward in an overhanging manner, a water drainage space 50 is formed at the rising base of the concave portion 40a. The chevron portion 43 and the folded holding portion 47 constitute a decompression space 45.

In the case of this first embodiment, the horizontal roof panels 3 on the eave side front stage and the ridge side next stage are engaged and connected to each other.
1, the overall rising height of the eave side and ridge side molded parts 33 and 34, which are engaged and connected to each other and serve as pressure receiving surfaces, is very high against wind and rain blowing up along the face plate part 32. The height is equal to the height of the rising part 40 and the falling part 36, which are connected to each other to form a series, and the joint part of both of them that is exposed to the outside is the upper part of the rising part 40. edge 41 and lower folded edge 37 at falling portion 36
This corresponds to the engaging abutting portion 46, which is in direct contact with the surface of the face plate portion 32 and rising at a substantially right angle, as in the case of the conventional example described above. There is no protrusion at the corner of the inner corner, which is located approximately in the middle of the rising pressure receiving surface as a whole, and furthermore, at the rising base of the rising portion 40, there is a protrusion that gradually overhangs in a curved shape. A water drainage space 50 exists due to the shaped portion, that is, in the case of the first embodiment, the concave portion 40a.

Therefore, in the configuration according to the first embodiment, the wind and rain blown up along the face plate part 32 will inevitably flow away from the same face plate part 32 in the same way as described above in the conventional example configuration. In this case, as is clear from FIG. 2, the part corresponding to the corner of the rising part 40 of the ridge side molded part 34 is concentrated at the corner of the internal corner rising at a right angle. It corresponds to the base, and from this base, the concave part 40
a is raised and forms the water handling space 50, so the wind and rain that concentrates on the base of this rising part 40 and, by extension, the water handling space 50, has no effect on the base. Since there is no abutting part, after blowing, the air flows upwardly along the protruding part, in this case the concave part 40a, smoothly on the one hand, and on the other hand, the base of the rising part 40. , and can be appropriately disposed of with almost no effect on the engaging abutting portion 46. In this way, the influence of wind and rain on the engaging abutting portion 46 can be sufficiently suppressed. It can be alleviated.

That is, in the case of the configuration according to the first embodiment, the engagement abutment part 46 is not present at the base of the rising part 40, and the rising part 40 and the falling part 36 are not present at the base of the rising part 40.
are connected in series, and since the concave portion 40a is formed in the rising portion 40, the wind and rain are given an upward direction by the concave portion 40a, and the wind and rain are directed upwardly by the concave portion 40a. It easily flows upward beyond the mating abutment portion 46, therefore, it does not exert an upward force-opening action on the falling portion 36, and at the same time flows in the longitudinal direction along the base where the mating abutment portion 46 does not exist. This year,
This makes it possible to effectively eliminate wind and rain as well as sand, mud, dust, etc. that come with the wind and rain from entering the engagement abutting portion 46.

At the same time, since the wind and rain that are constantly blown onto the base of the rising portion 40 concentrate and flow, it is impossible to imagine that sand, mud, dust, etc. may accumulate on the base, and as a result, the wind and rain have stopped. There is absolutely no possibility of sand, mud, dust, etc. flowing out, and therefore the roof surface can be effectively prevented from getting dirty.
Even if some rainwater enters from the engagement abutment part 46 due to capillary action, this small amount of rainwater will be absorbed into the decompression space that is connected to the inside of the engagement abutment part 46. 45, the intrusion pressure is sufficiently reduced and relaxed, and henceforth, it will not infiltrate further into the interior.

Furthermore, the manner in which the eave side and ridge side molded parts 33 and 34 engage, in other words, in the joint structure according to the first embodiment, the lower folded edge 37 of the falling part 36 in the eave side molded part 33 is folded inward to form a folded part 38, and since this folded part 38 is brought into contact with the receiving part 42, sufficient elasticity is imparted between these two parts. Due to the given elasticity, the contact pressure of the lower folded edge 37 of the falling part 36 against the upper folded edge 41 of the rising part 40 in the ridge side molded part 34 can be continuously and reliably maintained, and the folded part 38 The edge-bending portion 39, which is formed by bending the folded end of 42 and the folded holding part 47 sandwich and receive the folded part 38 including the edge bending part 39 of the eave side molded part 33, so that the horizontal roof panels 31 are separated from each other. There is no risk that such effects will occur.

Here, the folded-back holding part 47 is further folded back, and by bending it down to a position corresponding to the surface of the face plate part 32, a mounting part 49 for mounting and fixing is formed. Since this mounting portion 49 is formed
It can be extremely easily attached and fixed to the rafters 13 or the roof board surface with pegs, etc., and due to the existence of the double folded part in an elastic bending manner, The expansion and contraction in the width direction of each horizontal roof board 31 based on the difference can be fully absorbed, and the engagement mode of the molded parts 33 and 34 on the eave side and ridge side can be made to collapse due to this expansion and contraction in the width direction. This allows a good engagement to be maintained over a long period of time.

Next, FIGS. 3a to 3c show the configurations of second to fourth embodiments as modified examples of the protruding portions of the rising portions 40 in the configuration of the first embodiment.

In other words, in the configuration of the second embodiment shown in FIG. A rising inclined portion 40b is formed, and it is possible to obtain exactly the same operation and effect as the concave portion 40a in the configuration of the first embodiment.
In the configuration of the third embodiment shown in FIG.
By forming the downward slope portion 36a that tilts backward toward the engagement abutment portion 46, even if wind and rain accidentally occur toward the engagement abutment portion 46,
In addition, in the configuration of the fourth embodiment shown in FIG. By making the falling slope part 36b correspond to the degree of slope of the rising slope part 40b, the rising slope part 40b and the falling slope part 36b are both connected flush with each other in a forward tilted state. In addition to obtaining the same functions and effects as those of the previous embodiments, the flow of the water guided upward is made smoother, and the intrusion of water into the abutment portion 46 is prevented. It can be actively prevented.

Next, FIGS. 4a to 4d show the configurations of fifth to eighth embodiments, which are modified examples of the protruding portions of the rising portions 40 in the configuration of the first embodiment. .

That is, in the configurations of the fifth and sixth embodiments shown in FIGS. 4a and 4b, as the protruding portion of the rising portion 40, the portion close to the lower folded edge 41 and, furthermore, the engaging abutting portion 46 is provided. Leaving the flat surface portion 40c, a first rising step portion 40d and a first rising step portion 40d are provided on the rising base side of the flat surface portion 40c.
In the structure of each of these embodiments, in addition to obtaining the same functions and effects as those of the previous embodiments, spraying can be concentrated on the base. By suppressing the splashing of wind and rain as much as possible, it is possible to actively prevent water from entering the engaging abutment portion 46, and at the same time, it is possible to promote smoother flow of water at the base portion.

Furthermore, in the configuration of the seventh embodiment shown in FIG. 4c,
By abutting the rising part 40 forming the first rising step part 40d so as to cover the rising part 36c formed at the lower end inside the falling part 36 from the eave side, an engaging abutting part is formed. 46 is directed downward, and in addition to obtaining the same functions and effects as those of the previous embodiments, since the engaging abutting portion 46 is directed downward, there is no direct connection to the engaging abutting portion 46. This makes it possible to prevent wind and rain from blowing in and improve the drainage of rainwater, and at the same time, it is possible to improve the external appearance by hiding the engaging butt portion 46 from the outside.

Furthermore, the configuration of the eighth embodiment shown in FIG. 4d is as follows:
In the configuration of the fifth embodiment shown in FIG. 4a,
The attachment part 49 from the folded holding part 47 having the downwardly facing chevron part 43 is omitted, and instead of this, each part is attached with a hanger (not shown), etc., which is different from the fifth embodiment. Almost the same action and effect as the configuration can be obtained.

〔Effect of the invention〕

As detailed above, according to this invention,
It has a horizontal roof plate with 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 a ridge side molded part on the other side, and the ridge of the front side horizontal roof plate A horizontal roof joint structure in which the side molding part and the eave side molding part of the next horizontal roof board are engaged and connected to each other, and the eave side molding part has a falling part. The lower folded edge is lowered to form a lower folded edge, and this lower folded edge is folded inward to form a folded part with a bent edge at the end.The ridge side molded part has a rising part that protrudes inward in an overhang shape. After raising the raised base to form a protruding shape that embraces the water drainage space, an upper folded edge is formed to abut the lower folded edge, and this upper folded edge is bent outward to form an edge bend. The folded part including the folded part is used as a receiving part that receives the folded part, and a folded holding part having a downwardly facing chevron part is formed so as to cover the folded part from this receiving part.
The eave side molding part of the horizontal roof board on the next stage ridge side is fitted onto the ridge side molding part that is attached and fixed on the horizontal roof board on the front eave side, and the upper folded edge of the rising part is Both of these can be engaged and connected by a simple operation of butting the lower folded edges of the descending part, bringing the folded part including the edge bending part into contact with the receiving part, and receiving them into the receiving and holding part. In the horizontal roof structure constructed in this way, the butt joints at each folded edge of the upper and lower parts rise up from the face plate part. The wind and rain blown up along the face plate part are not directly blown onto this butt joint, and therefore the wind and rain from the engaging butt part and the wind and rain accompanying this wind and rain are not blown directly onto this butt joint. It can effectively eliminate the infiltration of sand, mud, dust, etc., and since the rising part has a protruding shape, it gives upward direction to the wind and rain. As a result, the sand easily flows upward beyond the engaging abutting part, and in order to prevent the falling part from being forced open upward, the sand can be properly disposed of by the wind and rain. It is possible to prevent the accumulation of mud, dust, etc., as well as the progression of corrosion and dirt caused by such accumulation.Furthermore, since a depressurized space is formed inside the butt joint, the intrusion of rainwater is prevented. It effectively reduces the pressure and effectively prevents rainwater from entering the interior, and the rising and falling parts that meet each other have sufficient pressure resistance to withstand snow loads. It is also strong and can prevent leaks, which are common in cold regions.

In addition, in the engagement mode at each of the eave side and ridge side molded parts, a folded part is formed by folding back from the lower folded edge of the falling part of the eave side molded part, and this folded part is pressed against the receiving part. Because of this, sufficient elasticity is imparted between these two parts,
Due to this given elasticity, the contact pressure of the lower folded edge of the eave side molded part against the upper folded edge of the ridge side molded part can be continuously and reliably maintained, and the pressure on the inside side of the folded part can be reduced. It is easy to form a space, and the mounting part for mounting and fixing is bent down from the folded holding part to a position corresponding to the face plate surface, so it is easy to use horizontal roofing with pegs, etc. In addition to making it easy to install the roof shingles, it can sufficiently absorb the expansion and contraction of each horizontal roof shingle in the width direction due to differences in outside temperature, and prevents the molded parts of the eaves and ridge sides from collapsing. However, the engagement and connection mode 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, so manufacturing is extremely easy and different from conventional methods. It has excellent features such as being able to offer it at an affordable price.
