Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a connection structure between an eaves gutter and a water collector in a folded plate roof of an entrance porch, etc.

[Background technology]

Conventionally, as shown in FIGS. 1 and 2, the structure of the eave end of this type of folded plate roof is such that a frame 2 is extended to the eave end of the roof panel 1, and this frame 2 is It is formed by mounting an eaves gutter 3 on the upper surface and attaching a decorative edge 4 to the lower surface of the frame 2, and as a drainage structure, drainage holes 5 are provided in the eaves gutter 3, the frame 2, and the decorative edge 4, respectively. The water collector 11 is made by drilling a drain hole 5, fitting a water collector 11 as shown in FIG. eaves gutter 3
The rainwater in the eaves gutter 3 is allowed to flow down from the cylindrical part 9 of the water collector 11. That is, as shown in FIG. 4, the locking portions 15, 15 of the locking pieces 14, 14 protrude from the upper end of the cylindrical portion 9 of the water collector 11 as a pair.
Insert the cylindrical part 9 of the water collector 11 into each drain hole 5 of the eaves gutter 3, the frame 2, and the decorative edge 4 while hooking it on the upper surface of the periphery of the drain hole 15 of the eaves gutter 3. The tightening ring 13 is fitted into the cylindrical portion 9 on the lower surface of the edge 4, and the tightening ring 13 is screwed into the threaded groove 8 formed on the outer periphery of the cylindrical portion 9 and tightened. The periphery of the opening of the eaves gutter 3, frame 2, and decorative edge 4 was clamped between the locking part 10 of the container 11. However, in this structure, as shown in FIG. 5, the upper and lower eaves gutters 3, the frame 2, and the decorative edge 4 are brought into close contact with each other at the locking piece 14 of the water collector 11, but the locking In areas where the part 15 has not been removed, there is a gap between the eaves gutter 3, the frame 2, and the facing edge 4, and rainwater enters between the gaps and corrodes the components that constitute them. Also, since the water collector 11 is hooked and fixed by two locking pieces 14, the installation strength is weak.
There is a drawback that the water collector 11 tends to come off from the eaves gutter 3 when the rain gutter chain 20 connected to the water collector 11 is pulled or when the wind blows.

[Purpose of the invention] The present invention was made in view of the above points, and it is possible to prevent rainwater from leaking from the connecting part between the eaves gutter and the water collector, and to firmly attach the water collector to the eaves gutter. The purpose of the present invention is to provide a connecting structure for eaves gutters and water collectors that can be fixed to a water collector.

[Disclosure of invention]

That is, in the present invention, a tightening ring 13 is screwed onto the outer periphery of a short cylindrical water collector 11 having a threaded groove 8 on the outer circumferential surface and a flange 10 on the upper edge. The eaves gutter and water collector are formed by sandwiching the inner edge of the drain hole 5 between the eaves gutter support frame 2 extending from the tip of the roof panel 1 and the eaves gutter 3 placed on the frame 2. In the connection structure with
A plurality of V-shaped grooves 6 are provided on the upper surface of the flange 10, and both horizontal ends of the U-shaped or V-shaped chain attachment bracket 21 with the rain gutter chain 20 suspended in the center are connected to the grooves 6.
By squeezing the inner edge of the drain hole 5 between the frame 2 and the eaves gutter 3 over the entire circumference, water leakage is eliminated. This system is characterized in that the drain is drained by the groove 6, and the chain attachment fitting 21 of the rain gutter chain 20 is attached using the concave groove 6.

The present invention will be explained in detail below with reference to Examples. As shown in FIGS. 1 and 2, a long frame 2 extends horizontally from the edge of the eaves of the roof panel 1, and the upper surface of the frame 2 has a roughly cross-sectional shape with an open top. A letter-shaped eaves gutter 3 is installed over the entire length. Further, a decorative edge 4 is attached to the lower surface of the frame 2. Concentric drain holes 5, 5, 5 are formed in the eaves gutter 3, the frame 2, and the decorative edge 4, respectively. As shown in FIGS. 6 and 7, the water collector 11 has a flange 10 extending outward over the entire circumference from the upper end outer periphery of a cylindrical tube portion 9 having a threaded groove 8 formed on the outer periphery. Two grooves 6, 6 extending from the outer periphery to the inside of the cylindrical portion 9 are provided on the upper surface of the flange portion 10. In the figure, reference numeral 13 denotes a tightening ring, and a threaded groove 12 is formed on its inner circumference.

Therefore, this water collector 11 is connected to the drain hole 5 of the eaves gutter 3.
When installing the water collector 11, the cylindrical part 9 of the water collector 11 is sequentially inserted into each drain hole 5, 5, 5 of the eaves gutter 3, frame 2, and decorative edge 4 from above.
The flange 10 of 1 is locked to the upper surface of the periphery of the drain hole 5 of the eaves gutter 3, and then the tightening ring 13 is secured to the upper surface of the periphery of the drain hole 5 of the eaves gutter 3.
into the cylindrical part 9 from below and thread groove 8 of the cylindrical part 9.
The periphery of the drain hole 5 of the eaves gutter 3, frame 2, and decorative edge 4 is clamped between the tightening ring 13 and the flange 10 of the water collector 11. The eaves gutter 3, the frame 2, and the decorative edge 4 are the flange 10 of the water collector 11.
By tightening the tightening ring 13, the drain hole 5 is opened.
The periphery of the frame is crimped uniformly and firmly over the entire circumference, preventing rainwater from entering the interior from between the eaves gutter 3 and the frame 2 and between the frame 2 and the decorative edge 4. Water collector 1
1 can be reliably attached to the eaves gutter 3. In addition, if a waterproof sealing material 17 such as a sealant or rubber seal is attached in advance to the entire circumference of the lower surface of the flange 10 of the water collector 11, the waterproofness between the flange 10 and the eaves gutter 3 can be further improved. It is something to do.
Furthermore, by forming the groove 6 on the upper surface of the flange 10 of the water collector 11, a small amount of rainwater accumulated in the eaves gutter 3 can be smoothly drained from the cylindrical part 9 through the groove 6. , it is possible to prevent water from accumulating in the eaves gutter 3. Moreover, this groove 6 is a water collector 1.
When attaching the rain gutter chain 20 to the U-shaped or V-shaped chain mounting bracket 21, insert the horizontal parts of both ends into the grooves 6,
6, and therefore the rain gutter chain 20 can be securely held in the event of strong winds, etc., and the chain attachment fittings 21 are stored in the recess, giving it a good appearance. .

[Effect of idea]

As mentioned above, the present invention consists of sequentially inserting the cylindrical part of the water collector, which has a cylindrical part with a threaded groove on its outer periphery and a flange extending outwardly at the upper end, into the drainage hole of the eaves gutter and frame. The flange of the water collector is secured to the upper surface of the periphery of the drainage hole of the eaves gutter, and a tightening ring with a threaded groove on the inner periphery is screwed onto the cylindrical part of the water collector, and the tightening ring and the flange are connected together. Since the eaves gutter and the frame are sandwiched between them, the periphery of the drain hole of the eave gutter and frame is tightened uniformly and firmly over the entire circumference between the collar and the tightening ring. This prevents rainwater from entering the interior from the space between the frame and the frame and the edge of the makeup area and corroding these components, and also prevents the water collector from easily coming off due to wind, etc. can be reliably prevented. In addition, since a groove is provided on the upper surface of the flange of the water collector that extends from the outer periphery to the inside of the tube, small amounts of water remaining in the eaves gutters can be drained through this groove. Since this concave groove is V-shaped, it is possible to store and attach the chain attachment bracket, which not only ensures the retention of the rain gutter chain, but also improves the appearance and prevents water from puddles. Since the amount of drainage is extremely small, even if the groove is V-shaped, it can sufficiently perform the drainage function.
