Description

[Detailed explanation of the idea] The present invention relates to a connection device for square eaves gutters.

The conventional method for connecting eaves gutters is to supply the eaves gutters to a joint that matches the outer circumferential shape of the eaves gutters, and then fit the ear edges of the eaves gutters with the ear edge locking parts provided on the side edges of the joint. has been adopted.

However, when square eaves gutters are connected using the above method, the eaves gutter body is pressed down by the edge locking portions, causing distortion, and the inner method has the disadvantage that it deforms outward and rainwater leaks.

The present invention has been made to solve the above-mentioned drawbacks, and its gist is that a band-shaped elastic fastening piece is attached along the width direction of the inner peripheral surface, and a fixing device is attached to the ear edge locking part. In addition, the eaves gutter is fitted into a rectangular joint whose inner circumferential shape substantially matches the outer circumferential shape of the eaves gutter, and the eaves gutter is fitted above a lattice-like partition plate having a rigidity that substantially matches the inner circumferential shape of the eaves gutter. A square eaves gutter is connected to a square joint by fixing fixtures attached to both side edges to fixtures of the ear edge locking part and fitting the partition plate to the eaves gutter. Exists in type eave gutter connection device.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view showing an example of a square joint A.

The square joint A is formed from a bottom surface 1 and a side wall 2, and its cross-sectional shape is a gutter-like body with a generally U-shaped opening at the top, and the inner circumference shape approximately matches the outer circumference shape of the square eaves gutter. An edge locking part 3 is provided at the upper end of the side wall 2 so that the edge of the square eaves gutter can be fitted therein.

Two band-shaped elastic water-stopping materials 4, 4 are attached to the inner circumferential surfaces of the bottom surface 1 and the side walls 2 along the width direction, and the elastic water-stopping material 4 is attached to the front of the ear edge locking portion 3. A semi-cylindrical fixture 5 is installed between them.

Also, the inside of the elastic stopper is made slightly smaller than the outside of the square gutter.

FIG. 2 is a perspective view showing an example of a grid-like partition plate opening.

The partition plate opening has a shape that approximately matches the inner peripheral shape of the square eaves gutter, and is made into a grid 6 to provide rigidity so that the outer peripheral part does not deform inwardly, and is designed to allow water to flow. There is.

Further, rod-shaped fixtures 7 are attached to the upper side edges of the partition plate opening.

FIG. 3 is a perspective view showing an example of the square eave gutter connection device of the present invention.

In the figure, C and 2 are square eaves gutters, and the ends of the eaves gutters C are fitted to approximately the center of the joint A, and the edges 8 are fitted into the edge locking portions 3 and fixed. ing.

Also, the end of the eaves gutter 2 is inserted into the joint A from the opposite direction to approximately the center thereof, and the edge 9 of the eave gutter 2 is fitted into the edge locking part 3 and fixed.

There is a slight gap between the eaves and gutters.

The rod-shaped fixing device 7 of the partition plate opening is inserted into the fixing device 5 and fitted inside the eaves gutter 2, and the elastic water stop material 4 is attached to the outside of the eaves gutter 2 by fitting the partition plate opening. The bottom surface and the side surface of the side surface are pressed between the bottom surface 1 and the side surface 2 of the inner surface of the square joint A, and the joint A and the eaves gutter C and 2 are connected.

The above-mentioned elastic stopper is a band-shaped elastic body that has water-stop properties when compressed, and includes, for example, synthetic leather rubber, natural rubber, synthetic resin foam, and the like.

Further, any method may be used for attaching the elastic water stop material, such as bonding with an adhesive, or attaching the elastic water stop material by providing a groove in the joint.

The configuration of the eaves gutter connection device of the present invention is as described above, and the edge of the square eaves gutter is locked by the edge locking part of the square joint, and the bottom and side surfaces are made of rigid grids. Since it is pressed by the bottom and side surfaces of the shaped partition plate, deformation of the eaves gutter is prevented or corrected, and the band-shaped elastic stopper is pressed against the bottom and side surfaces of the outer circumference of the eaves gutter and the bottom and side surfaces of the inner circumference of the square joint. Since the water is stopped by being compressed, there is no need to worry about rainwater leaking.

In addition, since the square joints, partition plates, and band-shaped elastic retainers are used to connect the eaves gutters, if the eaves gutters are connected with a slight gap between them, even if the eaves gutters expand or contract due to heat, they will not slide. will not warp or break.
