Abstract

PROBLEM TO BE SOLVED: To prevent a traversal joint part of mutual exterior finishing panels from becoming large and secure a waterproof function by inserting an external finishing panel provided with an engaging part and locking part into a recessed groove for insertion of a panel insertion member and superposing them at the top and bottom and laterally connecting them. SOLUTION: Exterior finishing panels 1c, 1d are inserted in recessed grooves 10a, 10b formed to be superposed with each other at the top and bottom and connected to a panel insertion part of the joint parts 2. The exterior finishing panels 1c, 1d are folded downward at the ends and the front ends is folded up to form a hook-shaped engaging part or the end is erected and turned back downward to form a locking part 14. Hence, the engaging part or the locking part 14 of one exterior finishing panel 1d is overlapped with the engaging part or the locking part 14 of the other exterior finishing panel from the downstream of the drainage slope. In this way, a sufficient insertion depth can be secured in respective insertion recessed grooves even if the panel insertion member is not made large. The exterior finishing panel can be prevented from coming off or positionally shifting due to a strong wind or the like and watertightness of respective insertion recessed grooves can be improved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure and a joint for a roof that is suitable for constructing, for example, a roof or an outer wall of a building structure such as a house by horizontally roofing a plurality of panel structural members. It concerns parts.

[0002]

2. Description of the Related Art In a so-called horizontal roof, a plurality of roof panels are connected in a direction perpendicular to a water gradient direction of a roof (hereinafter, referred to as a "horizontal direction"). As the structure (horizontal joint structure), (1) a type in which the edge of one roof panel is overlapped on an edge of one roof panel, and (2) a type in which the adjacent roof panels are horizontally connected by joint parts. And exists. In the above type (1), if the roof panels are simply overlapped with each other, the roof panels which are overlapped on the upper side by a negative pressure generated at the time of strong wind (a negative pressure generated at the time of generation of an air current that blows up on the roof). Is easily lifted, and the mouth is easy to open at the horizontal joint. Further, since the ends of the respective roof panels are goby-folded and joined, it is a three-dimensional process, and there is a problem that the process is troublesome.
In the type (2), the horizontal joint portion of the roof panel is pressed by a joint part, and the above-mentioned problem of floating is unlikely to occur. Therefore, the use of the type (2) horizontal joint structure is progressing.

FIG. 19 shows an example of the horizontal joint structure of the type (2). In FIG. 19, reference numeral 30 denotes a joint part, and both roof panels 1a, 1
It is arranged between b. The joint part 30 covers the water receiving portions 31 arranged on the left and right sides below the roof panels 1a and 1b, and the connection between the roof panels 1a and 1b from above to achieve waterproofness. The part 32 is composed of two parts. By inserting the roof panels 1a and 1b into the insertion grooves 33 secured between the cover part 32 and the water receiving parts 31 on both sides, the horizontally adjacent roof panels 1a and 1b are Connected. In this joint part 30, since the inundation into the insertion groove 33 in which the roof panels 1a and 1b are inserted flows down to the water receiving part 31 and is drained, it is possible to prevent water leakage from the joint part 30 to the roof foundation. .

However, in the horizontal joint structure as described above, the cover 32 is inserted into the insertion groove 31b between the water receiving portion 31 and the engaging piece 31a provided on the water receiving portion 31 at the site. It is necessary to insert the pair of leg portions 32a protruding from the front side (for example, insert from the near side of the paper) to assemble the joint part 30, and it is troublesome, and the workability is dissatisfied. . The joint part 30 has a structure in which the water receiving portions 31 are also arranged on the left and right sides corresponding to the respective roof panels on both sides to be connected horizontally, but on the upstream side of the water gradient, the connection between the upper and lower roof panels is made. Since the cover portion 32 corresponding to the portion is removed, it is necessary to take measures such as preventing water from entering with a water-stop packing in order to ensure the watertightness of the gap between the two water receiving portions 31, which takes time and effort. There is also a problem. FIG. 20 shows an example of a horizontal joint structure developed in view of the above problem.
In the horizontal joint structure shown in FIG. 20, the roof panels 1a and 1b adjacent to each other in the horizontal direction are connected to each other via a joint part 34 made of one part. Joint parts 34
Is formed by bending a single metal plate to form a substantially “D” shape. A cover portion 34a that covers a connection portion between the roof panels 1a and 1b from above, and a lower portion of the connection portion Between the roof panels 1a, 1b,
The insertion groove 34c into which the b is inserted is provided. Also in this joint part 34, similarly to the joint part 30 in FIG. 19, the water in the insertion groove 34c flows down to the water receiving part 34b and is drained, so that it is possible to realize waterproofing to the roof base side. In addition, since the joint part 34 is composed of one part, there is an advantage that construction is extremely easy. However, even with this joint part 34, the water receiving parts 3
4b is a structure in which the cover 34a is removed at the upstream end of the water gradient, where the cover 34a is in contact with the connection part of the roof panel above and below the water gradient. It is still unsolved that it is necessary to take countermeasures such as closing the packing with packing. However, in the case of a two-part joint part, it is relatively easy to realize a one-piece water receiver by attaching a cover to the dish-shaped water receiver. It is difficult to deviate from the configuration in which the water receiving portion is separated on both sides, and it is practically difficult to improve the watertightness of the upstream portion of the water gradient. In the end, the performance of the joint part consisting of two parts and the joint part consisting of one part,
Advantages and disadvantages in terms of workability.

[0005]

There have been many other proposals for the horizontal joint structure of the roof panel other than those described above. However, the number of members is small but the performance is not satisfactory, or the performance is satisfactory but the number of members is small. There were pros and cons, such as those with many, and what was excellent in a comprehensive sense was expected. In any joint structure, the basic structure is to connect the roof panel by inserting the roof panel into the insertion grooves provided on both sides of the joint part. In consideration of preventing the roof panel from coming off or displacing, the joint parts tend to be large. In other words, if the insertion groove is deepened, the roof panel can be prevented from coming off, and the contact area with the roof panel inserted into the insertion groove can be secured as large as possible, so that it can be clamped in the insertion groove. Since the pull-out resistance can be increased by increasing the force, there are cases where the joint parts are enlarged for these purposes.
Conventionally, a horizontal joint structure between roof panels has a configuration in which roof panels on both sides are connected so as to abut on substantially the same plane, and the insertion groove into which the roof panel of the joint component is inserted is also provided on both sides of the joint component. Therefore, if the insertion depths of the insertion concave grooves on both sides are increased, it is inevitable that the entire joint component becomes larger. However, when the size of the joint parts increases, the size of the cover part (for example, the cover part 32 of the joint part 30 and the cover part 34a of the joint part 34) that covers the connection between the roof panels increases, and There are problems such as affecting the appearance of the roof later. Further, if molding accuracy is also required for a large-sized joint part, there is a problem in that the production is troublesome and the cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a horizontal joint portion between exterior panels is provided by a panel insertion member provided with insertion concave grooves on both sides vertically overlapping each other. Without increasing the size, it is possible to securely connect with waterproofness, and it is also possible to reliably prevent inconvenience such as detachment of the exterior panel due to strong wind, etc. An object of the present invention is to provide a connection structure and a joint part of a horizontal roofing exterior panel which can provide an excellent appearance and can be reduced in cost by use.

[0007]

According to the first aspect of the present invention, an exterior panel connected in a direction substantially perpendicular to a water gradient direction is interposed between adjacent exterior panels via a panel insertion member into which an adjacent exterior panel is inserted. A connection structure of a horizontal roofing exterior panel that is connected, wherein the exterior panel is formed by bending a hook-shaped lower surface side at a downstream end of a water gradient, and
A locking portion formed on a protrusion that is folded back toward the upper surface side toward the downstream side of the water gradient on the upstream side of the water gradient and formed on a protrusion that is substantially orthogonal to the direction of the water gradient, and at least the locking portion along the direction of the water gradient. The insertion recesses formed on both sides perpendicular to the extending direction of the panel insertion member extending between the engagement portions are formed so as to vertically overlap each other. A connecting structure for a horizontal-roofed exterior panel, wherein the exterior panels inserted into the grooves are overlapped vertically and connected horizontally, is a means for solving the above-mentioned problem. According to this connection structure, the insertion groove on both sides orthogonal to the water gradient direction is provided by a panel insertion member that is provided so as to overlap each other up and down. The inserted exterior panel also vertically overlaps with the panel insertion member. The panel insertion member has a lateral dimension (in the extending direction of the panel insertion member) as compared with the case where the insertion groove is formed so as to face both sides in the horizontal direction due to the configuration in which the insertion grooves overlap each other. (The dimension in the direction perpendicular to the direction of the arrow) can be reduced. Further, the insertion depth of the insertion groove can be ensured without expanding the lateral dimension of the panel insertion member. By employing the insertion groove having a large insertion depth, it is possible to prevent the exterior panel inserted into the insertion groove from coming off due to the action of a strong wind or the like. In addition, since the adhesion between the inserted exterior panel and the inner surface of the insertion groove can be easily secured, the pinching force of the exterior panel in the insertion groove is sufficiently secured to increase the pull-out resistance. Also, it is easy to ensure the waterproofness of the insertion groove itself.

According to a second aspect of the present invention, in the connection structure of the horizontal roofing exterior panel according to the first aspect, a water receiving member whose periphery is surrounded by rising ribs is disposed immediately below the panel insertion member. It is characterized by the following. Even if the insertion groove is inundated, water does not leak to the lower side of the water receiving member due to drainage to the water receiving member below the panel insertion member.

According to a third aspect of the present invention, there is provided a joint part for connecting exterior panels connected in a horizontal direction substantially orthogonal to a water gradient direction, wherein the insertion grooves into which the exterior panels are inserted overlap each other. And a panel insertion member formed on the both sides facing each other. According to this joint component, the exterior panels are inserted into the respective insertion grooves from both sides of the panel insertion member, so that the exterior panels on both sides are connected while ensuring watertightness. However, since the panel insertion grooves are provided so as to overlap with each other, the exterior panels inserted into these insertion grooves also overlap with each other by the panel insertion member. The panel insertion member has a lateral dimension (in the extending direction of the panel insertion member) as compared with the case where the insertion groove is formed so as to face both sides in the horizontal direction due to the configuration in which the insertion grooves overlap each other. (The dimension in the direction perpendicular to the direction of the arrow) can be reduced. According to a fourth aspect of the present invention, in the joint part of the third aspect, a water receiving member whose periphery except a downstream end of a water gradient is surrounded by a rising rib is integrated with the panel insertion member. I do. In this joint part, since the panel insertion member and the water receiving member are integrated, the panel insertion member and the water receiving member can be collectively installed and constructed, and the workability can be improved.

[0010]

Embodiments of the present invention will be described below. In the present invention, as the exterior panel, a panel in which a heat insulating backing material is adhered to the lower surface side of a roof material is generally adopted.

As the roof material, a material having a heat insulating backing material adhered to the lower surface side may be used. As the heat-insulating backing material, a compressible polymer foam or the like is employed, and those having excellent heat-insulating properties are particularly suitable. As the compressible polymer foam material suitable as the backing material, a non-permeable foam of closed cells,
Those made of synthetic rubber, polyethylene, polystyrene, polyurethane and the like are suitable. In addition, the exterior panel is constructed on the heat-insulating waterproof sheet laid on the ground below the ground board, etc.,
It is also possible to ensure heat insulation by the heat-insulating waterproof sheet. In this case, even with an exterior panel made of a roofing material not covered with a heat insulating backing material, the same heat insulating effect as in the case where a heat insulating backing material is adhered can be obtained by the heat insulating waterproof sheet. Can be.

The exterior panel according to the present invention is, for example, an exterior panel for a roof panel, an exterior panel for a vertical building outer wall, and other various structures similar to a roof inclined with a water gradient. In any case, the connection (lateral connection) is performed in a direction substantially perpendicular to the water gradient direction (hereinafter referred to as “lateral direction”) by using the connection structure and the joint part of the present invention.

(Embodiment) An embodiment of the present invention will be specifically described below with reference to the drawings. This embodiment is an example in which the connection structure and the joint component according to the present invention are applied to connection between exterior panels as roof panels. FIG. 1 is a perspective view showing a roof constructed by applying the connection structure of the horizontal roofing exterior panel of the present embodiment. In FIG.
c to 1f are exterior panels and 2 is a joint part. The exterior panels 1c to 1f have the same configuration (the configurations of the exterior panels 1c to 1f are shown in FIGS. 9A and 9B). Hereinafter, a case where a common configuration is described without particularly distinguishing these components May be collectively referred to as “exterior panel 1”.

In the connection structure according to this embodiment, exterior panels 1c and 1d connected in a direction perpendicular to the direction of the water gradient of the roof (arrow A in FIG. 1) (hereinafter referred to as "lateral direction") are connected via joint parts 2. The exterior panels 1c and 1d that are laterally connected are also connected to exterior panels 1e and 1f that are adjacent to each other in the water gradient direction, and similarly, a large number of exterior panels 1 are vertically and horizontally connected. This constitutes the entire roof. However, the connection between the exterior panels 1 in the water gradient direction is made, for example, in a staggered manner so that the horizontal joints connecting the exterior panels 1 side by side do not line up and down in the water gradient direction. As the exterior panels 1c and 1d, those in which a heat insulating backing made of the above-described compressible polymer foam or the like is adhered to the lower surface side of a metal roofing material are used. FIG.

FIG. 2 shows an exterior panel 1 which is adjacent in the horizontal direction.
FIG. 3 is a cross-sectional perspective view showing a horizontal joint portion 1 </ b> A formed by connecting between c and 1 d with a joint component 2.
FIG. FIG. 14 is a cross-sectional view taken along CC of FIG.
FIG. 4 is a sectional view taken along a line and shows a state where exterior panels 1 c and 1 d on both sides are inserted into the joint part 2 of FIG. 3. FIG.
As shown in FIG. 14 and FIG.
The boundaries between the connected exterior panels 1c and 1d are covered with the cover 3 of the joint component 2 so as not to be exposed. The joint part 2 is formed by bending a single metal plate as a whole.
Panel insertion member 2a into which c and 1d are inserted from both sides
And a water receiving member 2b formed immediately below the panel insertion member 2a. Panel insertion member 2
Since a and the water receiving member 2b are formed from the same metal plate, they are integrated. In addition, in the joint part 2 integrated as a whole, since the panel insertion member 2a and the water receiving member 2b each constitute a part of the joint part 2,
Hereinafter, the panel insertion member 2a is referred to as a “panel insertion portion 2a”, and the water receiving member 2b is referred to as a “water receiving portion 2b”.
The material of the joint component 2 may be the same as the roof material.

The joint part 2 includes a panel insertion portion 2
a on the water receiving portion 2b.
Is placed such that the bottom plate 4 is placed on the roof foundation G. As shown in FIGS. 3 and 4, the water receiving portion 2 b is provided with rising ribs 5 a, 5 a around the bottom plate 4 formed flat.
It has a general tray shape on which b and 5c are formed. The rising ribs 5a, 5b, 5c are formed on the entire periphery of the water receiving portion 2b, which is inclined with the same water gradient as the roof, except for the water gradient downstream end 6. Rising rib 5a on one side in the horizontal direction perpendicular to the direction of the water gradient (left side in FIGS. 3 and 4)
And the rising rib 5b at the upstream end of the water gradient is a portion where the end of the bottom plate 4 is simply raised, while the rising rib 5c on the other side in the horizontal direction is a portion where the end of the bottom plate 4 is raised. , Which is folded back toward the bottom plate 4 to form a double structure.

The panel insertion portion 2a has a substantially S-shaped portion (in FIG. 2, etc., a shape obtained by inverting the "S" shape) from the water receiving portion 2b when the metal plate constituting the joint part 2 is raised from the water receiving portion 2b. (Illustrated in the drawing). Specifically, the panel insertion portion 2a includes a first flat portion 8 extending from a rising portion 7 raised from the water receiving portion 2b substantially in parallel with the water receiving portion bottom plate 4, and a first flat portion 8 extending from the first flat portion 8. The second flat portion 9 is formed by turning back and inverting from the tip of the portion 8 and extending substantially in parallel with the first flat portion 8, and turning back and inverting from the tip of the second flat portion 9 to substantially form the second flat portion 9. And a cover portion 3 extending in parallel. In detail, the rising portion 7 is a portion formed by raising a portion folded from the rising rib 5 c toward the bottom plate 4 so as to rise from the bottom plate 4. Insertion grooves 10a, 10b into which the exterior panels 1c, 1d are inserted are formed between the first and second flat portions 8, 9 and between the second flat portion 9 and the cover portion 3.
Each of these insertion grooves 10a and 10b is opened at the side of the panel insertion portion 2a, but the opening direction is just opposite to the opposite side of the panel insertion portion 2a. The insertion grooves 10a and 10b are separated from each other via a second flat portion 9, and the positions are shifted vertically so as to overlap with each other via the second flat portion 9.

As shown in FIG. 14, each insertion groove 10a,
The exterior panels 1c and 1d inserted into the panel 10b are substantially horizontally supported by rising ribs 5a, 5b and 5c projecting from the water receiving portion 2b at a position slightly away from the panel insertion portion 2a. Stable support. The rising ribs 5a, 5b, 5c, especially the rising ribs 5a, 5c on both sides of the panel insertion portion 2a,
The elastic ribs 5a, 5c are elastically deformed downward (toward the base G side, the same applies to the following) by the exterior panels 1c, 1d inserted in b.
The outer panels 1c and 1d are pushed upward (in a direction away from the base G; the same applies to the following) by the urging force acting from, and pressed against the upper inner surfaces of the insertion concave grooves 10a and 10b. Rain water on the panels 1c and 1d can be prevented from flowing into the insertion grooves 10a and 10b. Explaining in a little more detail, the exterior panel 1c inserted into the insertion groove 10a is pressed against the second flat portion 9 without a gap by the upward urging force acting from the rising rib 5c, and is inserted into the insertion groove 10b. The inserted exterior panel 1d is pressed without any gap against the fold portion 3a of the cover portion 3 by the upward urging force acting from the rising rib 5a.
Also in a and b, the inflow of water from the exterior panels 1c and 1d is prevented, and watertightness is ensured. As a result, the exterior panels 1c and 1d inserted into the panel insertion portion 2a are sandwiched while being inserted into the insertion concave grooves 10a and 10b. A pull-out resistance for preventing detachment from 10a and 10b is also generated. Note that a configuration in which the exterior panel 1 into which the insertion concave groove itself is inserted is sandwiched from both sides in the thickness direction may be employed to ensure watertightness.

In this joint part 2 and the connection structure using this joint part 2, the insertion concave grooves 10a and 10b opening on both sides facing the panel insertion part 2a are shifted up and down. Sa (insertion groove 10a,
10b is sufficiently secured (the dimension from the opening at the side of the panel insertion portion 2a to the innermost portion), so that the exterior panels 1c, 1d inserted into these insertion concave grooves 10a, 10b are provided.
d, even if slight displacement or deformation occurs due to, for example, a strong wind or snow load, or a coefficient of linear expansion of the roofing material with respect to the temperature difference between the cold and warm temperatures, the exterior panel 1 from the insertion grooves 10a and 10b.
c, 1d is unlikely to occur, and the connection state can be stably maintained. Exterior panels 1c from the insertion grooves 10a, 10b,
The prevention of detachment of 1d is not only that the insertion depth can be secured in the insertion grooves 10a and 10b, but also that the insertion grooves 10a and 10b
Exterior panels 1c, 1d resulting from an increase in insertion depth of 0b
Increases the pull-out resistance. That is, if the insertion depth is increased in each of the insertion grooves 10a and 10b, the contact area between the inner surfaces of the insertion grooves 10a and 10b and the exterior panels 1c and 1d can be increased. In the panel insertion portion 2a configured to sandwich the exterior panels 1c and 1d respectively inserted into 10b, the contact area increases,
The pull-out resistance of the exterior panels 1c and 1d from the insertion grooves 10a and 10b can be increased.
It is possible to prevent the exterior panels 1c and 1d from coming off and to be displaced from 10b.

Further, since the entire panel insertion portion 2a is formed of a metal plate and has a certain degree of elasticity, a slight displacement of the exterior panels 1c and 1d can be reduced by the elastic deformation of the panel insertion portion 2a. And allows slight displacement of the exterior panels 1c and 1d, so that local stress concentration and the like are more likely to occur than in the case where the exterior panels 1c and 1d are completely fixed at a predetermined installation position. Exterior panel 1
Inconveniences such as breakage and deformation of c and 1d are unlikely to occur. In addition, the insertion state of the exterior panels 1c and 1d into the insertion grooves 10a and 10b is determined by the insertion grooves 10a and 10b.
It is maintained stably due to an increase in resistance to withdrawal from b. In particular, in the joint component 2 illustrated in FIG. 4 and the like, the panel insertion portion 2a formed on the rising portion 7 raised from the water receiving portion 2b causes the exterior panel 1c to be elastically deformed by the plate-shaped rising portion 7. 1d, the displacement can be efficiently performed in response to the displacement of the exterior panels 1c, 1d.

FIGS. 5 to 7 show a modified joint part 2.
1, 22, and 23 are shown. These joint parts 21, 2
The only difference between the joint parts 2 and 23 is the shape of the bottom plate of the water receiving portion 2b. Each joint part 2
Also in the water receiving portions 21b, 22b, 23b of 1, 22, 23, the horizontal state of the exterior panels 1c, 1d is maintained by the rising ribs 5a, 5b, 5c of the water receiving portions, and the panel insertion portion 2a Each insertion groove 10a, 1
0b, rising ribs 5a, 5b, 5
It is the same as the joint component 2 that the exterior panels 1c and 1d are pressed by the urging force from c to prevent the insertion grooves 10a and 10b from being flooded. In the drawings, the same components as those of the joint part 2 are denoted by the same reference numerals, and description thereof will be simplified.

The joint part 21 shown in FIG.
A raised portion 21d is formed in the center of the bottom plate 21c of FIG. 1b. The raised portion 21d is trapezoidal, and the bottom plate 21c
The flat portion 21e at the tip of the projection direction (upper in FIG. 5) from
It is arranged so as to be attached to the first flat portion 8 of the panel insertion portion 2a. In this joint part 21, the panel insertion portion 2a sinks (FIG. 5) by the flat portion 21e arranged so as to be attached to the first flat portion 8 of the panel insertion portion 2a.
(Displacement in the middle and downward directions) and inclination are regulated, so that the orientation of the exterior panels 1c and 1d inserted into the insertion grooves 10a and 10b of the panel insertion portion 2a can be stably maintained. That is, the exterior panel 1c inserted into the insertion grooves 10a, 10b,
1d is the insertion concave grooves 10a and 10b and the rising rib 5
The supporting direction is determined by the relative positions between the panel insertion portions 2a and 5c. However, if the displacement or inclination of the panel insertion portion 2a is too free, for example, between the panel insertion portions 2a of the joint parts adjacent in the horizontal direction. The supported exterior panels 1c and 1d are likely to be deformed such as distortion. For example, the panel insertion portion 2a sinks in the direction of the water receiving portion 21b, and each insertion groove 10
When a and 10b are relatively lower than the rising ribs 5a and 5c, the ends separated from the joint components are pushed upward between the insertion concave grooves 10a and 10b and the rising ribs 5a and 5c. Such a displacement in the rotation direction is given to the exterior panels 1c and 1d, that is, the support direction changes. Therefore, in this joint part 21, the flat portion 21e of the raised portion 21d is arranged so as to be attached to the first flat portion 8 of the panel insertion portion 2a to suppress unnecessary sinking and inclination of the panel insertion portion 2a. Thus, stable support of the exterior panels 1c and 1d is realized.

The joint part 22 shown in FIG.
A raised portion 22d having a triangular cross section formed at the center of the bottom plate 22c of the base plate 2b is brought into contact with or close to the first flat portion 8 of the panel insertion portion 2a, and the panel insertion portion 2a is formed by the raised portion 22d. To prevent unnecessary sinking of
This is the same as the joint part 21 of FIG. However, in the joint component 22, contrary to the joint component 21, the inclination of the panel insertion portion 2a in the rotation direction about the top of the raised portion 22d is allowed, so that the bending acting on the exterior panels 1c and 1d is allowed. The deformation force such as twisting and twisting is efficiently absorbed by the displacement, inclination, deformation and the like of the panel insertion portion 2a.
It is intended to prevent partial damage or the like due to stress concentration of c and 1d.

The joint part 23 shown in FIG.
3b, ribs 23d formed from the bottom plate 23c are protruded at a plurality of locations on the bottom plate 23c. The rib 23d is a ridge that extends in the extending direction of the joint component 23, that is, the depth direction (the direction along the water gradient) in FIG.
Reinforcement of the water receiving portion 23b and rectification of the intruded water downstream of the water gradient,
Performs the function of drainage. Water receiving part 23b by rib 23d
There is no need to worry about water leakage to the side (direction perpendicular to the water gradient).
In FIG. 7, the rib 23 d is a small protrusion that does not contact the first flat portion 8 of the panel insertion portion 2 a, but the protrusion dimension is increased to the extent that the rib 23 d contacts or approaches the first flat portion 8. Needless to say, this is also possible.

That is, as a water receiving portion applied to the joint component, a water receiving portion base portion 2B (FIG. 8) is a region where a raised portion for preventing sinking of the panel insertion portion 2a and a rib for reinforcement are provided. Except that the configuration of the area indicated by hatches) is appropriately selected, the rising ribs 5a and 5c are commonly formed from both sides of the water receiving portion base 2B. It is common to form the rising rib 5b on the upstream side of the water gradient. In the present embodiment, the description will be continued by taking as an example a configuration employing the joint part 2 of FIG.

As shown in FIG. 2 and the like, in this connection structure,
The external panels 1c and 1d on both sides of the joint component 2 are inserted into and connected to the insertion concave grooves 10a and 10b formed so as to vertically overlap the panel insertion portion 2a,
The exterior panels 1c and 1d that are horizontally jointed via the joint part 2 are also vertically overlapped with each other at the panel insertion portion 2a, but as shown in FIGS. 9A and 9B,
The exterior panels 1c and 1d are provided with a water gradient downstream end (FIG. 9B).
The hook-shaped engaging portion 13 in which the middle left side is folded downward (middle and lower side in FIG. 9 (b)) and its tip is turned back to the water gradient upstream side, or the water gradient upstream end is raised to the water gradient downstream side Since the locking portion 14 turned back is provided, the exterior panels 1c and 1d are not simply superimposed on the joint part 2 vertically, but as shown in FIGS. The engaging portion 13 and the engaging portion 14 of the exterior panel 1c are opposed to the engaging portion 13 of the other exterior panel 1d.
And the locking portion 14 are overlapped from the downstream side of the water gradient. The engaging portion 14 also forms a finding portion 15 of the exterior panels 1c and 1d. Both the engaging portion 13 and the locking portion 14 are orthogonal to the water gradient (directions along the working length of the exterior panel 1).
The protrusion extends to In addition, the water receiving portion 2b
Also, the water cutting / folding portion 6a protruding downward from the downstream end 6 and turned toward the upstream of the water gradient is engaged with the locking portion 14 of the exterior panel 1e on the downstream side of the water gradient from the downstream side of the water gradient. (See FIGS. 11 and 12). The formation position of the locking portion 14 is not limited to the water gradient upstream end of the exterior panel 1, and may be a position slightly biased toward the water gradient downstream from the water gradient upstream end.

FIG. 11 is a sectional view taken along the line AA of FIG. 10, FIG. 12 is a sectional view taken along the line A'-A 'of FIG. 10, and FIG.
10 is a sectional view taken along line BB of FIG. 10, FIG. 14 is a sectional view taken along line CC of FIG. 10, and FIG. 15 is a sectional view taken along line DD of FIG. As shown in FIGS. 1, 10, and 11, the engaging portion 13 of the exterior panel 1 c inserted into the lower insertion groove 10 a on the lower side of the panel insertion portion 2 a of the joint component 2 is connected to the panel insertion portion 2 a Water gradient downstream end of the first flat portion 8 and the water receiving portion 2b
Is disposed so as to cover the water gradient downstream end 6 from the downstream side of the water gradient. On the other hand, the engaging portion 13 of the exterior panel 1d inserted into the upper insertion groove 10b is overlapped so as to cover the engaging portion 13 of the exterior panel 1c from the downstream side of the water gradient. The engaging portion 13 on the side of the exterior panel 1d is formed by cutting out a part of the engaging folded portion 13a which is folded from the finding portion 15 toward the upstream side of the water gradient (FIG. 9A).
And FIG. 16) with the engaging portion 13 on the side of the exterior panel 1c.
The notch 13b is inserted into the engagement turn-back portion 13a, so that the engagement portions 13 overlap each other in detail,
They are superimposed on each other. If the cutout portion 13b on the exterior panel 1d side is inserted into the engagement folded portion 13a of the engaging portion 13 on the exterior panel 1c side, the engagement folded portion 13a is made continuous between both exterior panels 1c and 1d. Therefore, for example, even when the exterior panels are connected to each other in the direction along the water gradient (vertical joint), the connection portion can be settled well, and the engaging portions 13 of both exterior panels 1c and 1d are connected to the downstream side of the water gradient. It is also advantageous for ensuring the watertightness of the vertical joint part which is engaged with the locking part 14 of the exterior panel 1e so as to overlap. In addition, the engagement turn-back portion 13 of the engagement portion 13
a is disposed below and below the drainage turn-back portion 6a engaged with the locking portion 14 of the exterior panel 1e on the downstream side of the water gradient, so that the water receiving portion 2b and the like are disposed downstream of the water gradient. It is not exposed from the side, and it is possible to prevent the intrusion of wind and rain that blows up.

From the downstream end of the water gradient of the cover portion 3, a fore-edge concealed portion 3b which is formed by folding downward is extended, and the engaging portion 13 (specifically, the finding portion 15) of the exterior panel 1d is located on the downstream side of the water gradient. It is superimposed so that it covers from. This little secret 3b
Prevents a water gradient downstream end of the cover portion 3 from being exposed, so that the appearance is secured. In addition, the front cover 3b prevents the gap between the cover portion 3 and the exterior panel 1d from being flooded by the fore-edge cover 3b.
Positioning of the engaging portion 13 with respect to the downstream end of the panel insertion portion 2a and misalignment (positional misalignment of the exterior panels 1c and 1d that protrude downward from the panel insertion portion 2a) can also be prevented. In FIG. 1 and the like, the fore-edge concealed portion 3b has such a size as to be overlapped only on the upper end of the finding portion 15 of the exterior panel 1d. However, the extension from the downstream end of the cover portion 3 is increased. It is also possible to have a size that covers the entire finding portion 15 of the exterior panel 1d. From the above configuration, at the water gradient downstream end of the horizontal joint portion 1A formed by connecting the exterior panels 1c and 1d to each other, since the engaging portions 13 overlap each other and no gap is generated between the panels 1a and 1b, for example, Even for wind and rain blowing up toward the upstream of the water gradient, the watertightness of the vertical joint with respect to the exterior panel 1e on the downstream side of the water gradient can be ensured.

On the other hand, at the water gradient upstream end of the horizontal joint portion 1A, the locking portions 14 of the exterior panels 1c and 1d are connected to the panel insertion portion near the water gradient upstream end of the panel insertion portion 2a of the joint part 2. 2a, the locking portion 14 of the other exterior panel 1d is overlapped with the locking portion 14 of the other exterior panel 1c from the downstream side of the water gradient. More specifically, the locking portion 14 on the side of the exterior panel 1c is connected to the locking portion storage groove 14c opened toward the water gradient upstream side by the locking portion 14 of the exterior panel 1d.
Superimposition is realized by storing inside. FIG.
As shown in (b), the locking portions 1 of the exterior panels 1c and 1d
Reference numeral 4 denotes a first folded portion 14a which is turned toward the downstream side of the water gradient so as to raise the roof material at the upstream end of the water gradient, and a second folded portion 14a which is folded from the first folded portion 14a to the upstream side of the water gradient.
A locking portion accommodating groove 14c that opens on the upstream side of the water gradient is provided between the turning portion 14b. As shown in FIG. 2, the locking portion storage groove 1 of the locking portion 14 on the side of the exterior panel 1d.
4c, a portion in which a notch 14d is formed at the water gradient downstream end of the locking portion 14 on the side of the exterior panel 1c is accommodated. Are overlapped so as to be continuous in the horizontal direction while the positions of the symbols are almost aligned. Therefore, the locking portion 14 of the exterior panel 1c is stored in the locking portion storage groove 14c of the locking portion 14 of the exterior panel 1d, so that the locking portions 14 of the both exterior panels 1c and 1d have no gap. Since the locking portions 14 on the exterior panel 1c side are sandwiched in the locking portion storage grooves 14c of the locking portions 14 on the exterior panel 1d side (in detail, the first and second folded portions are provided). 14a, 14b),
The connection state between both exterior panels 1c and 1d is stably maintained. As a result, in the horizontal joint portion 1A, even at the upstream end of the water gradient, the watertightness is secured by the overlapping of the locking portions 14 of the exterior panels 1c and 1d on both sides.

Each of the exterior panels 1c and 1d has an extending portion 14 that extends from the second folded portion 14b of the locking portion 14 to the upstream side of the water gradient.
The nail e is directly nailed (not shown) with respect to the base G, or the suspension 16 engaged with the locking portion 14 is nailed with the base G as shown in FIG. Hanger 16
In the case where is used, it is not necessary to provide the second folded portion 14b and the extending portion 14e in the locking portion 14, which can be omitted, and the exterior panel can be downsized. Further, the hook portion 1 of the suspender 16
6a is allowed to slide in the horizontal direction, and the exterior panels 1c and 1d are allowed to slightly move in the horizontal direction. Exterior panel 1 due to local stress concentration due to the deformation, the coefficient of linear expansion of the roofing material due to the temperature difference between the cold and warm temperatures, the action of strong wind, etc.
c, 1d can be prevented from being damaged. As shown in FIG. 15, since the extending portions 14e of the locking portions 14 of the exterior panels 1c and 1d are also vertically overlapped with each other, there is a slight change in the relative positional relationship between the exterior panels 1c and 1d. Even if it occurs, only the overlapping state of the extension portions 14e changes, and the extension portions 14e do not interfere with the displacement of the extension portion 14e on the other side, so that the extension portion 14e is locally damaged. Don't worry.

The engaging portion 13 of each of the exterior panels 1c and 1d connected by the horizontal joint portion 1A is overlapped with the locking portion 14 of the exterior panel 1e on the downstream side of the water gradient from the downstream side of the water gradient. It is engaged (see FIG. 11). Each exterior panel 1c, 1 connected by the horizontal joint 1A
The engaging portion 13 of the exterior panel 1f on the upstream side of the water gradient is engaged with the locking portion 14 of d so as to overlap from the downstream side of the water gradient (see the phantom line in FIG. 13). The roof shown in FIG. 1 connects the exterior panels 1c and 1d adjacent to each other in the horizontal direction by the horizontal joint 1A, and connects the exterior panels adjacent in the water gradient direction to the locking portion 14 of the exterior panel on the water gradient downstream side. To be connected to the engagement with the engaging portion of the exterior panel on the upstream side of the water gradient, and to connect a number of exterior panels vertically and horizontally (however, to prevent the horizontal joints of the exterior panels 1 from continuing vertically and horizontally). It is composed of

By the way, in the case of a conventional horizontal joint portion in which exterior panels are inserted into joint parts from both sides and connected so as to abut each other, for example, FIG.
9, the one shown in FIG. 20), in order to prevent infiltration of wind and rain from rising from the downstream end of the water gradient, the extension part which extends the water gradient downstream end of the cover part of the joint part, and the exterior panels on both sides In such a case, measures are taken such as covering the gap between the found portions so as to cover the gap, or closing the gap with a packing disposed inside the found portion (on the water gradient upstream side). On the other hand, in the connection structure according to the present embodiment, the engaging portions 13 of the exterior panels 1c and 1d on both sides of the joint component 2 (specifically, the finding portion 1).
5) can be sufficiently secured by a structure in which the gaps are overlapped with each other without a gap, so that there is no need to separately provide a configuration for covering the found portion, and the structure of the water joint downstream end of the horizontal joint 1A is simplified. Therefore, the size of the joint part 2 can be reduced, and the panel insertion part 2a of the joint part 2 can be simplified and the cost can be reduced.
Due to the miniaturization of the downstream end of the water gradient, the outer panel
Can be reduced in size, whereby an excellent aesthetic appearance can be obtained. For example, the size of the found portion 15 (dimension t in FIG. 1) is 1
It becomes possible to use an exterior panel of about 2 mm or less. Conversely, even if the found portion of each exterior panel 1 is enlarged, excellent water tightness can be secured by overlapping the found portions. In this manner, if the configuration is such that the watertightness is ensured by overlapping the found portions, the watertightness can be easily ensured corresponding to various found portion sizes, and the degree of freedom of the found portion size can be improved. And there is an advantage that the design of the exterior panel 1 can be widely supported.

By applying this connection structure, the exterior panel 1c,
As a general method of laterally connecting 1d to each other, first, the working length direction (a direction perpendicular to the working width) of one of the exterior panels (here, the exterior panel 1c). The dimension L of the panel 1e in FIG.
1), a joint part 2 is attached to one end of the base part G, and the joint part 2 is arranged at a target position on the base G. Next, as shown in FIG. 17, the exterior panel 1d (working width portion) is inserted into the upper insertion groove 10b of the two insertion grooves 10a and 10b of the panel insertion portion 2a of the joint component 2. The exterior panel 1c (working width portion) is inserted into the lower insertion groove 10a. Here, the engaging portions 13 (found portions 15) of both exterior panels 1c and 1d are overlapped with each other, and the engaging portion storage groove 14c of the engaging portion 14 of the exterior panel 1d.
Then, the locking portions 14 of the exterior panels 1c and 1d are overlapped with each other so that the locking portions 14 of the exterior panel 1c are stored. Therefore, the exterior panel 1 with respect to the exterior panel 1c
The connection operation d is performed by sliding the outer panel 1 into the insertion groove 10b by lateral movement (arrow B in FIG. 17).
An operation of pushing up from a position slightly shifted to the downstream side of the water gradient with respect to c is added. The working width portion of the exterior panel 1d is inserted into the insertion groove 10b of the panel insertion portion 2a, and the locking portion 14 of the exterior panel 1c is stored in the locking portion storage groove 14c of the exterior panel 1d. When the locking portion 14 of the panel 1d is inserted into the locking portion 14 of the exterior panel 1c, the exterior panel 1d is pulled out of the exterior panel 1c by the clamping force acting on the insertion concave groove 10b and the locking portion storage groove 14c. Is regulated, so that the insertion state is stabilized.

In the joint part 2, the cover part 3 of the panel insertion part 2a is smaller than the second flat part 9,
The cover part 3 folded back from the flat part 9 covers a part of the second flat part 9, and the second flat part 9 near the innermost part of the insertion groove 10a.
Are exposed in a plan view, and the exterior panel 1d is inserted into the insertion groove 10b so as to be in contact with the exposed portion of the second flat portion 9, whereby the insertion groove of the exterior panel 1d is inserted. The insertion work into 10b can be performed efficiently. In addition, even in the vicinity of the insertion groove 10a, the insertion work can be performed efficiently by attaching the exterior panel 1c to the rising portion 7 that is gently bent from the insertion groove 10a. In FIG. 4 and the like, the rising portion 7 is bent near the insertion groove 10a, but it is more preferable that the bending angle be as gentle as possible or curved in view of the workability of inserting the exterior panel 1c.

The roof (see FIG. 1) in which a large number of exterior panels are connected vertically and horizontally by the horizontal connection of the exterior panels and the connection between the exterior panels adjacent to each other in the water gradient direction by the connection structure according to the present invention can be used for rainfall or the like. Flows down from the exterior panel on the upstream side of the water gradient to the exterior panel on the downstream side in the same manner as a normal roof. However, as shown in FIG. 2, the joint component 2 disposed in the horizontal joint 1A between the exterior panels 1c and 1d is configured such that the insertion concave grooves 10a and 10b into which the exterior panels 1c and 1d are inserted overlap vertically. Since it is formed, the insertion depth of each of the insertion concave grooves 10a and 10b can be increased to a depth substantially equal to the width of the panel insertion portion 2a.
Since each of the insertion concave grooves 10a and 10b is inserted with the respective exterior panels 1c and 1d, excellent watertightness is secured, so that it is possible to reliably prevent water leakage from the horizontal joint portion 1A downward. The cover portion 3 of the panel insertion portion 2a forms an insertion groove 10b for storing the tip of the exterior panel 1d inserted above the exterior panel 1c with respect to the panel insertion portion 2a while ensuring watertightness. Since it is sufficient to have a size as large as possible, it is possible to reduce the size as compared with a cover portion of a conventional configuration which needs to have a size to accommodate the front ends of the panels on both sides to be connected and to cover the entire connection portion. Therefore, the exposure of the cover portion 3 on the roof can be made extremely small, and there is an advantage that an excellent aesthetic appearance can be obtained.

In the roof shown in FIG. 1, one end in the working length direction of the exterior panel installed between the joint parts 2 adjacent to each other in the horizontal direction is connected to the insertion groove 1 in the upper part of the joint part 2.
0b, and the other end is inserted into the lower insertion groove 10a of the other joint part 2. The working length L1 of the exterior panel is about several thousand mm (for example, 3000 mm). The height difference between the concave grooves 10a and 10b is about 0.4 to 1 mm which is the thickness dimension of the second flat portion 9 of the panel insertion portion 2a, and this height difference is caused by the panel insertion of the joint parts 2 on both sides. Since it is absorbed by the elastic deformation of the portion 2a itself, there is no problem in construction and in securing watertightness. Panel insertion part 2 to absorb height difference
Even if a is elastically deformed, the adhesion between the inner surfaces of the insertion grooves 10a and 10b and the exterior panel inserted therein (particularly, the adhesion with the upper inner surfaces of the insertion grooves 10a and 10b) is stably maintained. It has no effect on ensuring stable watertightness.

Even if a leak occurs from the horizontal joint 1A, the leak flows into the water receiving portion 2b disposed immediately below the panel insertion portion 2a and is discharged according to the water gradient. (2) Water leakage to the lower side and the ground G side can be reliably prevented. Since the water receiving portion 2b is inclined with the same water gradient as that of the entire joint part 2, the water flowing into the water receiving portion 2b flows downward according to the water gradient of the water receiving portion 2b, and FIG. As shown in FIG.
b flows down onto the exterior panel 1e on the downstream side of the water gradient from the downstream end 6 and is drained smoothly. Further, as shown in FIG. 14, each exterior panel 1 inserted into the panel insertion portion 2a
The rising ribs 5a and 5c on both sides of the water receiving portion 2b abut against the lower surfaces of the water receiving portions 2b and 1d, respectively, to ensure watertightness, so that water leakage from the water receiving portion 2b can be reliably prevented.
Particularly, rising ribs 5a on both sides of the water receiving portion 2b are provided on the compressible backing material attached to the lower surfaces of the outer panels 1c and 1d.
In the configuration in which 5c abuts with an urging force, excellent watertightness is stably obtained, and water leakage from water receiving portion 2b can be reliably prevented. Needless to say, the fact that the entire joint part 2 is formed as a single piece from a single metal plate also contributes to watertightness (prevention of water leakage) to the surroundings. This is the same for the other joint parts shown in FIGS. 5 to 8.

As described above, in the joint component according to the present invention and the connection structure using the same, the miniaturization of the cover portion 3 reduces the exposure of the cover portion 3 at the horizontal joint portion 1A, thereby obtaining an excellent aesthetic appearance. At the same time, the insertion grooves 10a and 10b having a large insertion depth can prevent the displacement of the exterior panels 1c and 1d inserted therein,
The water tightness of a, 10b itself can be dramatically improved.

The present invention is not limited to the configuration of the above embodiment, and various modifications and changes are possible. The application object of the connection structure of the present invention is not limited to the roof, for example, a building outer wall,
The present invention can be applied to waterproof exterior of various structures such as various structures similar to a roof. The exterior panel is not limited to a roofing material having no heat-insulating backing material adhered thereto, or a roofing material having a heat-insulating backing material adhered thereto, and various configurations can be adopted. For example, a configuration in which a thin plate-shaped solar cell module is attached to the surface (upper surface), a configuration in which a planar heating element is attached to the surface, or a configuration in which the planar heating element is sandwiched can be adopted. . As a configuration for ensuring the watertightness of the insertion groove of the panel insertion member (panel insertion portion 2a), for example, an exterior panel in which a packing inserted into the insertion groove inner part is inserted into the insertion groove. A configuration in which the tip is pressed by the tip or a configuration in which the packing attached to the tip of the exterior panel inserted into the insertion groove is pressed against the innermost part of the insertion groove can be adopted. In these configurations, the packing that is in a compressed state in the insertion groove prevents water from entering the insertion groove, thereby ensuring excellent watertightness.

In the above embodiment, the joint part 2 in which the panel insertion member (panel insertion part 2a) and the water receiving member (water receiving part 2b) are integrated has been exemplified.
In the invention described in 3, the configuration is not limited to the configuration in which the panel insertion member and the water receiving member are integrated, but also includes a configuration in which these are separated and a configuration in which only the panel insertion member is provided. For example, when sufficient watertightness is ensured only by inserting the exterior panel into the insertion groove, the exterior panels can be laterally connected using only the panel insertion member alone. The joint component is not limited to the integral molding from a single metal plate, but may be, for example, an integrally molded product of a resin material. However, it is suitable to use a metal plate from the viewpoint of ensuring sufficient deformability to follow the displacement of the exterior panel and sufficient strength. Also, as shown in FIG. 18, for example, as shown in FIG. 18, the panel insertion member 51 and the water receiving member 52 are bonded and fixed by an adhesive or a double-sided adhesive tape 53 (a panel insertion member). 5
Various configurations, such as the fixing portion 51a of the first and the bottom plate 52a of the water receiving member 52) or those integrated by fixing by welding or the like (the joint part 50 in FIG. 18) can be adopted.

[0041]

As described above, according to the connection structure of the horizontal roofing exterior panel of the present invention, the panel is formed such that the insertion grooves on both sides perpendicular to the water gradient direction are vertically overlapped with each other. By the insertion member, the exterior panel inserted into the insertion groove from both sides of the panel insertion member also overlaps vertically with the panel insertion member, so that each panel insertion member does not need to be enlarged. A sufficient insertion depth can be ensured in the insertion groove, whereby the displacement prevention performance (extraction resistance, etc.) of the exterior panel in each insertion groove can be enhanced to prevent the exterior panel from coming off against the action of a strong wind or the like. Prevention of displacement and improvement of watertightness in each insertion groove can be realized. In addition, by reducing the size of the panel insertion member, an excellent effect is achieved in that the exposed portion of the insertion material on the connection portion is reduced, so that the appearance can be improved and the cost can be reduced. According to the connection structure of the exterior panel of the horizontal roof according to claim 2, since the water receiving member whose periphery except for the downstream end of the water gradient is surrounded by the rising rib is disposed immediately below the panel insertion member. Even if the indentation groove should be flooded, there is an excellent effect that the drainage to the water receiving member below the panel insertion member does not cause water leakage to the lower side of the water receiving member.

According to the joint part of the third aspect,
The insertion groove into which the exterior panel is inserted is formed so as to be overlapped with each other, and is provided with a panel insertion member which is opened on both sides facing each other. The lateral dimension (dimension in the direction orthogonal to the extending direction of the panel insertion member) can be reduced as compared with the case where the insertion concave groove is formed so as to face the panel insertion member. In addition, there is an excellent effect that watertightness can be ensured by minimizing the generation of gaps on the upstream side of the water gradient. According to the joint part of the fourth aspect, since the water receiving member whose periphery is surrounded by the rising rib is integrated with the panel insertion member, these panel insertion member and water receiving member Can be installed and constructed in a lump, and an excellent effect that the workability can be improved can be achieved.
