Description: TECHNICAL FIELD The present invention relates to a roof plate connecting structure for connecting each end of an array roof plate to a roof receiving frame, and more particularly to a rain finish thereof.

[Conventional technology]

BACKGROUND ART Conventionally, a roof plate connection structure is known in which the ends of two roof plates are connected to a roof support frame. For example, the one described in Japanese Utility Model Laid-Open No. 60-130927 is shown in FIG.

In FIG. 7, a roof support frame 101 is fixed to a base material 100. This roof support frame 101 is a base material 100
A first frame 102 fixed to the first frame 102 and a second frame 104 fixed to the first frame 102 with a fastener 103. Second
The frame 104 is formed with projecting piece portions 105, 105 that project obliquely downward and outward from above. One end portion 107 of the first (left) roof plate 106 extends a rising portion 108 that rises obliquely upward along the roof receiving frame 101, and both frame members 1
A bag-shaped portion 110 is formed by folding back along a recess 109 formed between 02 and 104, and the bag-shaped portion 110 is further extended and folded back upward to form an engaging portion 111. The other end 112 of the second (right) roof plate 106 horizontally extends a rising portion 113 that rises obliquely upward along the roof receiving frame 101, covers the upper side of the roof receiving frame 101, and further hangs downward obliquely. While lowering, the hanging part 114 is folded back to engage with the lower part of the engaging part 111 of the first roof plate 106.
have. This engaging portion 115 is further extended to the first
A blocking portion 116 that contacts the bag-shaped portion 110 of the roof plate 106 and closes the gap between the roof plates 106, 106 is formed.

[Problems to be Solved by the Invention]

However, according to the above configuration, when exposed to a storm,
Since the air pressure is higher outdoors than indoors,
Even if 6 is provided, rainwater may enter the bag-shaped portion 110. The rainwater that has infiltrated the bag-shaped portion 110 reaches the tip of the engaging portion 111 from a minute gap between the engaging portion 111 and the engaging portion 115 due to a pushing pressure due to a strong blowing wind, a capillary phenomenon, or the like. The second frame is blown inward from the tip of the engaging portion 111, passes through a gap between the outer upper portion of the bag-shaped portion 110 of the first roof plate 106 and the inner surface of the second roof plate 106, and then the second frame. It is blown toward the member 104. However, since the second frame member 104 is not provided with the gutter, the rainwater will be dropped inside the room through the roof receiving frame 101. Therefore, it is impossible to sufficiently prevent the leakage of rain during a storm.

The present invention has been made in view of the above-mentioned conventional drawbacks, the edge of the roof plate is not lifted during construction, the roof plate is not meandering and deformed, and rain leakage can be sufficiently prevented even during storms. Furthermore, it is an object of the present invention to provide a roof plate connection structure capable of completely preventing the end portions of the roof plate from coming off due to wind pressure during a storm.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the first invention of the roof plate connection structure according to the present invention is such that the gutters formed at the ends having the rising portions of the roof plates on both sides face each other on the roof receiving frame. It is characterized in that both ends are locked to the roof receiving frame by clips arranged and pressed from above the both ends, and caps are fitted to the clips from above.

Further, according to the second invention, a gutter portion formed at one end portion having a rising portion of one roof plate is arranged on a roof receiving frame, and one end thereof is attached by a clip attached by being pressed from above the one end portion. Part is locked to the roof support frame,
A cover portion that covers the upper portion of the clip pressed on the gutter portion is provided at the other end portion of the other roof plate, and the closing portion formed in the hanging portion that extends downward from the cover portion has The feature is that it comes in contact with the roof plate body.

[Action]

According to the first aspect of the present invention, since the end portion of the roof plate is pressed and locked to the roof receiving frame by the clip, it is possible to prevent the end portion from rising and facilitate the construction. In addition, even if rainwater enters from the end of the roof plate, this end has a rising portion, and since this end is pressed and locked to the roof receiving frame by a clip, rainwater does not easily enter and the cap Even if rainwater enters from the fitting portion of the roof storm during the storm, the rainwater flows into the trough formed at one end or the other end of the roof plate and is drained by the trough. Further, since the gutter is formed at the end having the rising part, and this gutter is provided near the top of the roof receiving frame, even if rainwater enters from the fitting part during a storm, this rainwater will be guttered. Difficult to penetrate into parts.

According to the second aspect of the invention, the construction can be facilitated similarly to the first aspect of the invention, and even if rainwater invades from the closed portion in contact with the other roof plate during a storm, this rainwater is formed at one end of the roof plate. It flows into the gutter and is drained by this gutter. Also,
Even if rainwater enters from the closing part, the gutter part is formed at the end part having the rising part, and since this gutter part is provided near the top part of the roof support frame, the rainwater from the closing part to the gutter part is Since the infiltration route is long, it is difficult for rainwater to infiltrate into the trough.

On the inner surfaces of both roof plates 12 and 12, there are provided heat insulating materials 12b and 12b having waterproof property, such as urethane of independent foaming. The roof receiving frame 3 is made of a material thicker than the roof plates 12, 12.

Both end portions 13 and 14 of the roof plates 12 and 12 extend along one side of the roof receiving frame 3, and a rising portion 16 that rises upward from the roof plate body 12a is folded back to the outside to form the second frame. An engaging portion 17 that engages with the lower end of the protruding piece portion 6 of 6 via a heat insulating material 12b is provided. Both ends 13 of this roof plate 12,12,
The reference numeral 14 bends the engaging portion 17 to form an inclined portion 18 that rises obliquely upward, and the second portion is formed in the middle of the inclined portion 18.
It has a curved portion 19 formed along the curved concave portion 10 of the frame 6. Further, the both end portions 13 and 14 are bent in the horizontal direction to extend to the vicinity of the top of the roof receiving frame 3 and are bent to form a trough portion 20. That is, the gutter portion 20 is provided above the rising portions 16 of the both end portions 13 and 14 of the roof plate 12.

The trough portion 20 is folded back to form a reinforcing end portion 21.

Furthermore, even if rainwater soaks, this rainwater is clip 23C
24C or a trough portion 20C formed at one end portion 13C of one roof plate 12 flows into both trough plates 12 and 12 and is inclined in the longitudinal direction (direction perpendicular to the paper surface). Can be drained by 24C.

That is, since the gutters 20C and 24C are provided near the top of the roof receiving frame 3, the rainwater infiltration path becomes long, so the gutters 20C and 24C are provided.
It is difficult for rainwater to penetrate to C, and even if rainwater enters the troughs 20C and 24C, rainwater can be drained by the troughs 20C and 24C.

Further, the roof plates 12 and 12 are both projecting pieces 9 and 9 of the roof receiving frame 3.
Since it is supported in an engaged state with the roof plates 12 and 12, there is no need to make holes in the roof plates 12, 12 and the workability and water resistance are excellent. Further, since the thick roof receiving frame 3 is used, the strength of the connecting portion is increased.

Further, in the above-mentioned embodiment, the case where the clip is long has been described, but if the clips 23, 23B and 23C are made short and are provided on the roof receiving frame, the gutter function of the clip does not work as described above. Similarly, the roof plate can be reliably supported in the engaged state.

In the case of the first embodiment, a short clip 23 may be appropriately provided between the roof receiving frames.

〔The invention's effect〕

As described above, according to the present invention, since the end portion of the roof plate is pressed and locked to the roof receiving frame by the clip,
It is possible to prevent the other end from rising and prevent the roof plate from meandering and deforming, thereby facilitating the construction.

Also, at the edge of the roof plate, since the gutter part is provided above the rising part, since the rising height to the gutter part is high, it is difficult for rainwater to enter, and even if it enters the gutter part, the amount is small,
Rainwater that enters the gutter is drained by the gutter.

Further, since the end portion of the roof plate is securely pressed and locked to the roof receiving frame by the clip, it is possible to completely prevent the end portion of the roof plate from coming off due to the wind pressure during a storm.

Moreover, since the end of the roof plate is extended to the vicinity of the top of the roof receiving frame, and the gutter is formed near the top,
As the rainwater entry path to the gutter becomes longer, and the rising height to the gutter becomes higher, it is difficult for rainwater to enter the gutter, and even if the gutter enters a small amount, it does not enter the gutter. The rainwater is drained by the gutter. Therefore, it is possible to prevent rain leakage even during a storm.
