Description

[Detailed Description of the Invention] In the present invention, the eaves gutter itself expands and contracts due to temperature differences between cold and warm temperatures.

This invention relates to an expansion/contraction absorbing eaves gutter joint that absorbs the expansion and contraction and prevents deformation such as meandering of the eaves gutter and damage to eave gutter joints and gutter parts such as bending.

Various types of expansion/contraction absorbing eaves/gutter joints have been proposed to absorb the expansion/contraction of the eaves gutter itself.

Among them, haha is an expandable absorbing plate in which the central part is made into a bellows part that can be expanded and contracted, and eave gutter connection parts are extended to both ends of the bellows part so that one side is a fixed side and the other is a movable side. The eaves gutter joint is formed by forming an eaves gutter joint and disposing the expansion/contraction absorbing plate part on the inner periphery of the eaves gutter joint body formed along the outer circumference of the eaves gutter. When making the connection,
The bellows part expands and contracts in accordance with the expansion and contraction of the eaves gutter, so that the expansion and contraction of the eaves gutter can be very well absorbed, and the eaves gutter can be simply and easily connected to each other.

In the case of eaves gutter joints in which multiple holes are drilled in the fixed side eaves gutter connection part, the expansion and contraction absorbing plate part can be more firmly fixed to the eaves gutter joint body through the holes with adhesive or the like. It is possible.

When connecting eaves gutters, adhesive is used, but depending on the position and amount of adhesive applied, the adhesive may protrude or drip.

In that case, there was a risk that the appearance would become unsightly or that the fluid would flow into the movable part, that is, the back surface of the bellows part, impairing the elastic function.

The present invention was devised to solve the above-mentioned drawbacks, and will be explained below based on the drawings shown as embodiments.

FIG. 1 is a perspective view of an embodiment of the present invention. In the figure, 1 is an expansion/contraction absorbing plate part, and 2 is an eaves gutter joint body.

The expansion and contraction absorbing eaves gutter joint according to the present invention is formed by disposing the expansion and contraction absorbing plate portion 1 on the inner circumferential surface of the eaves gutter joint body 2.

The eaves gutter joint body 2 is formed along the outer periphery of the eaves gutter, and is made of a material such as hard synthetic resin or metal.

FIG. 2 is a perspective view of the elastic absorption plate section 1 of another embodiment,
In the figure, 11 is a bellows part, 12 is a movable eave gutter connection part,
Reference numeral 13 represents a fixed side eave gutter connection portion, 14 represents a hole, and 15 represents a recessed portion.

The elastic absorption plate part 1 is formed by interposing a bellows part 11 between a movable side eaves gutter connection part 12 and a fixed side eaves gutter connection part 13.

The bellows part 11 is expandable and contractible in the eaves gutter connection direction and absorbs the expansion and contraction of the eaves gutter, and the movable side and fixed side eave gutter connection parts 12 and 13 connect the eaves gutter and are attached with adhesive. This is where I get involved.

The movable side eaves gutter connection part 12 is a part that can slide, that is, move, on the inner peripheral surface of the eaves gutter joint body 2 as the bellows part 11 moves according to the expansion and contraction of the eaves gutter when the eaves gutter is connected and constructed. The fixed side eaves gutter connection part 13 is a part whose back side is fixed to the eaves gutter joint body 2, and holes 14, 14, . . . are formed therein.

Then, on the back side of the fixed side eaves gutter connection part 13, there is a hole 14°1.
A recess 15 communicating with 4... is provided.

FIG. 3 is an enlarged view of the main part of the fixed side eave gutter connection part 13 from the rear surface direction, and the recessed part 15 is provided over the circumferential direction when disposed in the eave gutter joint body 2.

As shown in Fig. 4, protrusions 3, 4, 5.6 may be provided,
In this case, the adhesive can be prevented from dripping and the adhesive layer can be easily formed.

FIG. 5 is an enlarged sectional view of the main part of the eaves gutter connection construction state. When adhesive B is applied and eaves gutter A is connected, the adhesive B protrudes from the back side of the bellows part 11 due to the pressure. However, it is absorbed into the space of the recess 15 and does not protrude or hang from the end of the eaves/gutter joint body 2.

The expansion/contraction absorbing eaves gutter joint according to the present invention is capable of expanding and contracting in the eaves gutter connection direction between the fixed side eaves gutter connection part in which a hole is drilled and the movable side eaves gutter connection part that slides when the eaves gutter expands and contracts. A bellows part is interposed to form an elastic absorption plate part, and the elastic absorption plate part is attached to the inner circumference of the eaves gutter joint body formed along the outer circumference of the eaves gutter, so that the movable side eaves gutter connection part is in a movable state. This expansion/contraction absorbing eaves gutter joint is arranged as shown in FIG. A uniform adhesive layer can be formed without dripping or sagging, improving the appearance and connecting eaves gutters more firmly.
