Description

[Detailed description of the invention] This invention is designed to prevent the eaves gutter from expanding or contracting due to the difference in temperature or temperature during the day, causing deformation such as meandering or bending of the eaves gutter. This invention relates to an eaves gutter expansion joint that prevents the eaves gutter from coming off from bridge parts such as joints, or from damaging the parts themselves.

Various types of expansion eave gutter joints have been considered.

Among them, on the inner periphery of the eaves gutter joint body, there is an elastic absorbing plate part with eave gutter connection parts formed at both ends of a bellows-like body that can be freely expanded and contracted in the eave gutter connection direction. The expandable eaves gutter joint arranged so as to absorb the expansion and contraction of the eaves gutter very well.

Moreover, it is time-consuming to use adhesive to fix the other eaves gutter connection part (fixed side) of the elastic absorption plate part to the inner surface of the eaves gutter joint body, and furthermore, the elastic absorption plate part is made of soft synthetic resin. Because it is made of aluminum, it does not slip easily with the hard synthetic resin eave gutter joint body that serves as the movable surface, making it difficult to absorb the expansion and contraction of the eaves gutter.

The object of the present invention is to provide an expansion joint that can smoothly absorb expansion and contraction of eaves gutters.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be explained based on drawings shown as embodiments of the present invention.

FIG. 1 is a perspective view of the eaves gutter expansion joint of the present invention. In the figure, 1 is the eave gutter expansion joint, 2 is the joint base, and 3 is the expansion/contraction absorption plate portion.

The joint base body 2 has a concave portion 22.2 in which the ear portion of the eaves gutter fits into the upper edge of the gutter-like body 21 formed along the outer periphery of the eaves gutter.
2 is formed.

The recess 22 is formed in a curved manner.

Then, on the inner surface of the gutter-like body 21 of the joint base 2, a soft synthetic resin plate portion 23 having a length approximately equal to the length of the eaves gutter connection portion 31 of the expansion/contraction absorption plate portion 3 described later is formed on the inner surface of one end. ing.

The joint base body 2 itself is made of hard synthetic resin.

The expandable/contractable absorption plate part 3 has eave gutter connecting parts 31, 31 extending from both ends of an extensible part 32 which is expandable and contractible in the connecting direction of the eaves gutter.

A hard synthetic resin plate part 33 made of hard synthetic resin is provided on the back surface of one of the eaves gutter connecting parts 31.

The elastic absorbing plate section 3 itself is made of soft synthetic resin.

As shown in FIG. 2, the telescopic eaves gutter joint 1 connects the eave gutter connecting plate part 31, in which the back surface of the telescopic absorption plate part 3 is formed of a hard synthetic resin plate part 33, to the soft synthetic resin plate part 23 of the joint base 2. The expansion and contraction absorbing plate portion is attached to the joint base body 3 so that it is located on the inner peripheral surface 24 of the end portion where no It is arranged on the inner periphery.

The other eave gutter connection portion 31 (the side on which the hard synthetic resin plate portion 33 is not formed on the back side) of the expansion/contraction absorption plate portion 3 is connected to the joint base 2
It will be arranged on the soft synthetic resin plate part 23 of.

That is, the eaves gutter connection part 31 with the hard plastic or resin part 33 formed on the back side becomes the movable side, and the other eaves gutter connection part 31 becomes the fixed side.

As shown in FIG. 2, the eaves gutter 1 whose outer surface is made of soft synthetic resin is fitted into the expandable eave gutter joint 1 to connect the eaves gutter to each other.

Since the present invention is as described above, the movable surfaces, that is, the inner circumferential surface of the joint base and the back surface of the movable side eave gutter connection part of the expansion and contraction absorbing plate part, are made of the same hard synthetic resin, and have very good sliding. It can respond to the expansion and contraction of the gutter, and the other fixed surface is made of soft synthetic resin, so it is extremely resistant to slipping.If the eaves gutter is continued, it will stick tightly and will not slip, so it can be fixed without adhesive. can do.

Claims (1)

[Scope of utility model registration request] An eave gutter connection part is provided at both ends of the expandable part that can be expanded and contracted in the connection direction of the eaves gutter, and a hard synthetic resin plate part is formed on the back side of one of the eave gutter connection parts to create a flexible synthetic resin expansion and contraction absorbing plate. A recess into which the eaves gutter ear part is fitted is formed on the upper edge of the gutter-like body formed along the outer periphery of the eaves gutter, and the expansion/contraction absorption is applied to the inner surface of the gutter-like body from one end. A soft synthetic resin plate portion having a length approximately equal to the length of the eaves gutter connecting portion of the plate portion is formed to serve as a hard synthetic resin joint base, and the eaves gutter connecting portion whose back surface is the hard synthetic resin plate portion is jointed. The flexible absorbing plate is placed on the inner surface where the soft synthetic resin plate part of the base body is not formed, and the eave gutter connection part whose back surface is made of hard synthetic resin can be slid freely on the hard synthetic resin inner surface of the base body. A telescoping eaves gutter joint characterized by having a portion arranged inside a lightweight base.
