Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a connection structure of a square gutter used as a gutter or the like.

(Prior Art and Problems) A square gutter is mainly used as a gutter to draw rainwater from a water collector attached to the eaves to a vertical gutter attached to the wall of a building.

In other words, since the gutter is installed under the eaves to match the length of the eaves, it requires a lot of work to cut and connect them to match the length of the eaves.

Conventionally, when connecting square gutters like this, in the case of metal gutters, the ends to be connected were overlapped and connected by soldering etc.
With this method, the soldered parts may corrode, and the strength is likely to be insufficient, and if the solder is exposed on the outside, the appearance after construction may be impaired.

In particular, since the gutter is installed almost horizontally under the eaves, it is susceptible to deflection due to its own weight, so the connecting parts needed to be particularly strong.

(Purpose of the invention) The present invention improves the strength of the connection part of such a square gutter, and since it is connected by an engaging plate and a fixed plate, it can be made stronger by conventional soldering, etc. The present invention provides a square gutter connection structure that is easy to construct because no work is required, and has a good appearance after construction.

(Structure of the invention) The present invention will be described below based on an embodiment shown in the accompanying drawings.

Figure 1 shows an exploded perspective view of the square gutter 1, fixing plate 2, engaging plate 3, and engaging plate 4. Each part is made by bending a metal plate such as a copper plate, and the upper part is open and the cross section is The substantially U-shaped square gutter 1 has an edge 11 formed by bending the upper edge inward, and further bends the tip downward to form a hanging piece 14, and the lower end of the hanging piece 14 has a fixed A plurality of engagement grooves 15 are cut at intervals.

The fixing plate 2, the engagement plate 3, and the engagement plate 4 are made by press-molding a slightly thick metal plate, and two inverted L-shaped flanges 21 are provided at both ends of the fixing plate 2, and An engagement hole 23 is formed at the side end, and a long hole 22 is formed at the underwater side end.

On the other hand, the engagement plates 3 and 4 are each arranged and attached inside the square gutter 1, but the engagement plate 3 has its side ends raised up and has standing pieces 33, 33, and one end of the end in the direction of the gutter is raised up. The engagement piece 31 is erected, and the side of the other end is raised up to provide engagement pieces 32, 32, and a screw hole 34 is bored in the center.

Further, the engagement plate 4 is provided with an upright piece 42 at the side end, one end in the gutter direction is upright, and an engagement piece 41 is provided upright, and a screw hole 43 is bored in the center.

The square gutters 1 are connected and fixed together using each part configured as above, but the lower end of the square gutter 1 is fitted inside the other square gutter, and the upper end is bent inward. Edge 1
A mating end portion 12 having a diameter of 3 is extended.

On the other hand, when connecting, the engagement plates 3 and 4 are attached to the bottom side of the fixing plate 2 with screws 24, but the fixing piece 2
The engagement hole 23 provided on the above water side and the screw hole 34 of the engagement plate 3 are loosely temporarily fixed with the screw 24, and the screw hole 43 of the engagement plate 4 is inserted into the elongated hole 22 on the below water side with the screw 2.
Temporarily fix it in step 4.

After temporarily fixing the fixing plate 2 and the engaging plates 3 and 4 in this way, slide the fixing plate 2 and the engaging plate 3 to the above water side by sandwiching the edge 11 from the underwater side of the square gutter 1. , the engaging pieces 31 and 32 are engaged with the engaging grooves 15, and the screws 24 are tightened to secure them as shown in the perspective view of FIG.

Next, while externally fitting the square gutter 1 connected to the underwater side into the fitting end 12 of the square gutter 1, insert the end between the fixing plate 2 and the engagement plate 4, and engage the engagement piece 41. After engaging with the groove 15, the screw 24 is tightened to fix it.

At this time, the upright pieces 33 and 42 of the engagement plates 3 and 4 are used as stoppers to prevent the hanging pieces 14 from expanding outward.

FIG. 3 shows a perspective view when the square gutters 1 are connected and fixed together in this way.
Reference numeral 2 is used to move and fix the engagement plate 4 to an arbitrary position even when the position of the engagement groove 15 and the engagement piece 41 are misaligned.

In this way, the connection work is completed, but if you apply adhesive or the like to the outer circumferential surface of the fitting end 12 of the square gutter 1 and fit it, it will be completely secure against water leakage. It is something.

(Effect of the invention) When connecting square gutters in this way, the upper edges of the square gutters are sandwiched between the fixing plate and the engagement plate, so the square gutters can be firmly attached even when installed horizontally as a gutter. It can be easily connected and does not require skilled work such as soldering, so it can be easily constructed, has no fear of corrosion, has a good appearance, and can withstand long-term use.
