Description

[Detailed Description of the Invention] The present invention relates to an improvement in the assembly structure of a square rain gutter which is assembled with four side plates made of metal, and at least one side of which is formed into a complicated curved shape.

Normally, rainwater that falls on the roof flows into the open eaves gutter a installed at the eaves, as shown in Figure 1.
Rainwater flowing into the eaves gutter a is collected in a water collector b, and from the water collector b is led to a vertical gutter d along the outer wall of the building via a vertical anchor body c, etc., and flows down to the ground. The water collector b, the vertical anchor body c, etc. are decoratively formed so as not to spoil the beauty of the building. In the water collector b, a pattern is applied to the outer surface to give it an aesthetic appearance, but in the vertical anchor body c, etc., the outer plate 1 or the outer plate 1 and the corresponding inner plate 2 have a complex curved surface. It looks beautiful. And the conventional vertical anchor body c
For assembly, each side plate was welded and fixed by soldering (see Figure 2).

However, in this conventional method, since the outer plate 1 and inner plate 2 of the vertical anchor body c have complicated curved shapes, it is not only difficult to weld them, but also to join the outer plate 1 and the inner plate. Misalignment may occur between the flanges 3a, 3b, 4a, 4b of the left and right side plates 3, 4, making it impossible to make them come into close contact with each other. There were drawbacks such as causing

As a solution to this drawback, Figures 3 and 4
As shown in the figure, the flanges 3a, 3b, 4a,
Square holes 5a, 5b, 6a, 6 are provided at each corner of 4b.
b, and locking claws 7a, 7b, 8a, at positions corresponding to the square holes on both side edges of the outer plate 1 and inner plate 2.
8b is formed, the locking claws are inserted into the square holes, the side plates 1 to 4 are folded and temporarily assembled, and then soldered and fixed by welding. However, in this device, the flange 3
During the bending press in step a, an irregular tensile force acts around the square hole 5a, deforming the square hole 5a, making it difficult to insert the locking pawl 7a, and also causing solder 9 to form around the locking pawl. The soldering work is troublesome because it has to be thickly plated, and
Even if the solder 9 is thickly applied around the locking claw,
Since the solder does not enter between the joint surface of the locking pawl and the flange, rainwater often leaks from this area, so there is a disadvantage that a water leak test must be performed after the assembly work and the soldering work must be performed again. Ta.

Therefore, the present invention was developed in view of the above-mentioned drawbacks of the conventional methods, and even if the gutter has a complicated curved side plate, it can be easily assembled, and the rain can be drained in one time. The object of the present invention is to provide a structure for assembling a square rain gutter that can reliably prevent soldering.

Therefore, in the present invention, the assembly structure of the square rain gutter has an outer plate and an inner plate formed in a complicated curved shape, and locking claws are provided at appropriate intervals on both side edges of the outer plate and inner plate. At the same time, a notch groove narrower than the locking pawl is formed at a position corresponding to the locking pawl on the flanges of the left and right side plates to which the both side edges are welded and fixed, and a notch groove narrower than the locking pawl is formed at the base of the notch groove. After drilling an insertion hole into which a locking pawl is inserted, and inserting the locking pawl into the insertion hole, bend the locking pawl so as to cover the notch groove, and then solder the left and right side plates. The intended purpose is achieved by welding and fixing the flanges to both side edges of the outer and inner plates.

The present invention will be explained below based on an example in which the present invention is applied to the vertical anchor body c shown in FIG.

The vertical anchor c is composed of four thin metal plates: an outer plate 11, an inner plate 12, and left and right side plates 13 and 14. The outer plate 11 and the inner plate are formed by being bent into a curved shape so that the surfaces thereof have a substantially wavy curved surface shape, and a plurality of locking claws 17a, 17 are provided at appropriate intervals on both side edges of each.
b, 18a, and 18b are formed. Further, the surfaces of the left and right side plates 13 and 14 have linear smooth surfaces, and the outer side plate 11 and the inner side plate 12 are formed on both side edges.
Flanges 13a, 13b, which are joined to both side edges of
14a and 14b are formed to match the curved shapes of the outer plate 11 and the inner plate 12.
Each of the flanges 13a to 14b is provided with each of the locking claws 1.
Notch grooves 20 made narrower than the locking claws 17a to 18b at positions corresponding to the locking claws 17a to 18b, respectively.
a, 20b, 21a, and 21b are respectively formed, and insertion holes 22a, 22b, 23a, and 23b into which the locking claws 17a to 18b are inserted are continuous at the base of each of the notch grooves 20a to 21b, respectively. It is formed by

By the way, when bending and pressing the side plates 11 and 12, the notch grooves 20a to 21b and the insertion holes 2 are cut in advance.
Although notches 2a to 23b are formed,
By configuring the insertion holes 22a to 23b as in the present invention, even if the hole shape is deformed due to tension during bending press, the hole will not be deformed in the direction of becoming smaller, and the hole will always be larger. This is very advantageous because it deforms in the direction.

In order to assemble the side plates 11 to 14 made as described above to form the vertical anchor body c, the outer plate 1
After inserting each of the locking claws 17a to 18b of the inner plate 12 and the left and right side plates 13 and 14 into the insertion holes 22a to 23b, the locking claws 17a to 18b cover the notch grooves 20a to 21b. Tighten and temporarily secure. After that, solder 19 is applied to each of the flanges 13a to 14b and both side edges of the outer plate 11 and inner plate 12.
The welding will be fixed. As a result, the solder 19 is applied to each of the notch grooves 20a to 21b and each of the insertion holes 22a to 22a.
It easily flows into the notch grooves 20a to 23b.
21b is filled with solder 19, and a vertical anchor body c is formed.

Although the above embodiment has been described as an example in which the present invention is applied to a vertical anchor body c, the present invention is not limited to this embodiment, and may be applied to other modified square gutter such as a shamido anchor body or a square gutter. Furthermore, during assembly, each side plate was temporarily fastened and then soldered, but one side plate may be temporarily fastened and soldered, and then the other side plate may be soldered.

As described above, according to the present invention, locking claws are formed at appropriate intervals on both side edges of a side plate having a complicated curved shape, and the flange of the other side plate at a position corresponding to the locking claws is A cutout groove narrower than the locking claw is formed, and an insertion hole into which the locking claw is inserted is continuously drilled at the base of the cutout groove, and the locking claw is inserted into the insertion hole. After insertion, the locking pawl was bent so as to cover the notch groove and temporarily fixed, and then each side plate was welded and fixed by soldering, so that the solder did not enter the notch groove and the insertion hole. Since the solder easily flows into the grooves and fills the notched grooves, it is possible to reliably weld and secure the parts without applying a thick layer of solder. Therefore, the soldering work is easy and the assembly is reliable, so it is possible to completely prevent rain from getting wet with just one soldering work, and it is possible to prevent the build-up of rain by a tensile action during the bending press work of the side plate. Even if the insertion hole is deformed, the insertion hole deforms in the direction of increasing its size, so that the inconvenience of the hole being crushed can be reliably prevented and the locking pawl can be easily inserted.
