DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for an eaves gutter to be installed on an eaves portion of a house roof.

[0002]

2. Description of the Related Art In recent years, the number of homes with a small site area has increased in houses mainly in urban areas, so that space between the building and the neighborhood cannot be taken, and in order to make the room wider, the eaves are less protruding. Buildings are increasing.

In order to construct an eaves gutter in a building having a small eaves, the eaves are connected in accordance with the length of the eaves. At this time, an eaves gutter is used to connect the ends of the eaves. And fix the periphery so that water leakage does not occur. For this reason, conventionally, a method has been adopted in which the periphery of the connecting portion of the eaves gutter is sandwiched between an outer plate and an inner plate coated with a sealing material or the like and connected. That is, an outer plate is arranged around the outer edge of the end of the eave gutter, and an inner plate is similarly arranged around the inner periphery.

In order to perform connection with such a joint, no gap should be formed in the connection portion, and the appearance after the connection must not be impaired. A gap is likely to be formed between the eaves gutter and the joint, but this may cause water leakage and impair the function of the joint. Therefore, when connecting such eaves gutters with joints, it is necessary to carry out the work easily and to perform the construction so that no gap is formed between the eaves gutters and the joints.

[0005]

As described above, when a conventional eaves gutter is constructed in a building with little eaves and connected by using joints, the appearance of the building must be kept intact. If the position from the eaves to the eaves gutter is far away, it is relatively easy to perform construction to eliminate the gap, but use a joint in a place where the fascia and the eaves gutter are in contact. Was sometimes difficult.

That is, since the nose shield is in contact with the back side of the eaves gutter, it is difficult to perform a work such as nail bending as in the conventional case, and a gap is opened between the joint and the eaves gutter in the conventional joint structure. And could not be constructed. If this gap occurs, water leakage may occur during long-term use, and the appearance after the construction is impaired.

[0007]

In order to satisfy the above-mentioned conditions, the eaves gutter joint according to the present invention requires a joint structure in which an eaves gutter is attached and constructed so as to be in contact with a nose cover at an eaves. As a means for this, a pressing piece elastically projecting inward is formed on the upper part of the inner plate, and an engaging projection is formed on the upper part to engage with the ear of the eave gutter.

That is, a joint having a structure in which an end of an eave gutter is sandwiched between an outer plate and an inner plate, wherein an upper end of the inner plate is bent inward, and an engaging protrusion formed on the upper portion is bent. It is structured to be fixed to the engaging piece of the gutter lug.

[0009]

The joint of the eaves gutter, which is the object of the present invention, connects the eaves gutters to be installed on the eaves of the roof. It is engaged by pressing from below. Due to this inner plate structure, a force acts on the upper end of the engagement projection to lift the eaves gutter ears upwards, and as a reaction, a force acts on the bottom plate in the direction of pressing the eaves gutter downward, so that the inner plate is always in the eaves gutter. Since the structure is pressed against the inner peripheral surface of the gutter, no gap or the like is generated between the eaves gutter and the inner plate after construction.

That is, the eaves gutter joint according to the present invention is constructed so that the eaves gutter is sandwiched between the outer plate and the inner plate, and the upper end of the inner plate is bent inward to form an upper part. This is a structure in which the joint projection is fixed to the engaging piece of the eave gutter ear. By the action of the engagement projections of the inner plate, the inner plate is pressed downward to eliminate a gap with the eaves gutter. By eliminating the gap, the sealing material does not break and water leakage does not occur, and even in a building with little eaves, the eaves and the design of the building are not spoiled.

In addition, the construction can be easily performed without any gap as in the case of the conventional joint, and particularly when the eaves gutter is constructed at a position close to the eaves, the construction can be easily performed without the need for skill, and the water leakage can be prevented. There is no fear that the appearance will be good after construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 shows an eaves gutter D and a joint G according to the present invention,
Fig. 2 shows a perspective view of the construction at the tip of the roof.
FIG. In the construction site in the illustrated example, arabesque F is attached to the tip of a base plate B, and a roof plate A is constructed on the upper surface thereof.

The eaves gutter D is formed by bending a steel plate of about 0.4 mm to 0.6 mm or a zinc-aluminum-plated steel sheet to a length of 2 m to 4 m, and the main body 1 has a front plate 11, a back plate 12, and a bottom plate. It has a substantially U-shape with an upper part opened by the face plate 13. The type of this material is not fixed, and the thickness and length are determined by the size of the eaves gutter to be formed, and are not particularly limited to these values.

At the lower part of the front plate 11, two steps 14 are formed along the horizontal direction (FIG. 2).
This is to enhance the design and enhance the design after construction by emphasizing the horizontal lines. The eaves gutter shape may assume various shapes other than the present embodiment, and is not limited to the illustrated example.

The upper edges of the front plate 11 and the rear plate 12 are bent so as to be lowered inward to form ears 15,
The ear portion 15 is provided with an inclined piece 15a that is inclined inward, and the lower end thereof is bent outward to form an engaging piece 15b. The upper edge of the back plate 12 is also bent inward to be substantially triangular in shape, like the front plate 11, with the inclined pieces 15a and the engagement pieces 15b. At this time, the engagement piece 15b is formed to be slightly shorter, and has a structure in which a gap is formed between the front plate 11 and the back plate 12 of the eaves gutter D.

The joint G shown in FIG. 1 is formed of the same material as the eaves gutter D, and comprises an outer plate 2 and an inner plate 3. (FIG. 2) As shown in FIG.
2. The bottom plate 23 is formed into a shape that comes into contact with the outer peripheral surface of the eaves gutter D.

Two steps corresponding to the eaves gutter D are formed at an intermediate portion of the front panel 21 of the outer panel 2, and a holding piece 2 is formed at the upper end.
A winding piece 25 is provided upright via 4. This winding piece 2
5 is formed by bending the upper end of the front plate 21 once downward along the inclined piece 15a of the eaves gutter D to form a holding piece 24, and furthermore, bending it almost vertically. At this time, a slit hole 26 is formed at the base of the vertically bent portion at two places along the longitudinal direction of the eaves gutter D to facilitate the winding operation.

The slit hole 26 is formed so as to be easily bent when the winding piece 25 is bent and wound around the ear 15 of the eaves gutter D. Is not particularly limited because the bending position is different depending on the shape of.

From the upper end of the back plate 22, a contact piece 27 elastically bent toward the back side is bent. In the example shown, the contact piece 27 is formed by bending the entire back plate 22. Although it is formed, the width and the like may be appropriately designed.
(FIG. 2) The contact piece 27 prevents the rattling of the eaves gutter D by pressing the nose shield C at the time of construction.

On the other hand, as shown in FIG. 2, the inner plate 3 is disposed so as to be substantially inscribed in the eaves gutter D, and is formed into a substantially U-shaped cross section by a front plate 31, a back plate 32 and a bottom plate 33. A step is formed by bending two steps in the middle of the step.

From the upper ends of the front plate 31 and the back plate 32 of the inner plate 3, a pressing piece 34 bent substantially inward and substantially horizontally is provided.
Is formed, and its tip is bent downward for reinforcement. On the upper surface of the pressing piece 34,
Engaging projections 35 projecting in a curved shape are formed at two places each.

The central portion of the inner plate 3 extends along the peripheral surface,
A protruding portion 36 protruding from the inner periphery and having an outer periphery as a groove is formed by being extruded by a press or the like, and by applying a sealing material 37 or the like to the outer peripheral groove portion of the protruding portion 36 at the time of construction. The abutting portion of the edge of the eaves gutter D is securely sealed to prevent water leakage (FIG. 3).

At the time of construction, an arabesque F is constructed on the eaves of the field board B, a roof slab A is constructed on the upper surface thereof, and a fascia C installed at the lower part of the eaves is constructed with a gutter D. (FIG. 1) The bottom plate 13 of the main body 1 of the eaves gutter D is installed so as to be flush with the lower surface side of the eaves gutter, and when the eaves gutter D and the eaves girder are connected, the external appearance is obtained. Is being improved. Further, as described above, the width of the nose cover C in the up-down direction is determined by a standard, and the width of the eaves gutter D can be further enhanced by adjusting the width to an appropriate size.

In the illustrated example, the eaves gutter D is constructed by abutting the back plate 12 of the main body 1 through which rainwater flows against the nose shield plate C. It is constructed with some gaps.

As described above, the eaves gutter D is connected to the nose cover C at the eaves.
At the same time, the base plate B and the like at the eave have a protruding length determined from the blindfold plate C (about 30 mm in the example shown in FIG. 3).
If it is cut down, rainwater flowing down from the roof can be completely introduced into the eaves gutter. As a guide of this length, the position of the tip of the roofing material A is such that the center of the eaves gutter D is attained, and varies depending on the width of the eaves gutter D or the like.

The roofing material A is fixed to a base plate B or tarki, and the roof material A is installed from the lower end of the fascia plate C. The eaves gutter D is constructed on the fascia plate C with metal fittings or the like, but in order to connect the eaves gutters D, the connecting edges are closely opposed to each other.

Then, as shown in FIG. 3, a joint G is constructed. First, the outer plate 2 is covered so as to be fitted to a joint portion between the eaves gutters D. At this time, the holding piece 24 is attached to the eaves gutter D. The outer plate 2 does not fall because it is brought into contact with the inclined piece 15a and the wound piece 25 is engaged so as to wind the ear portion 15. (FIG. 4)

The contact piece 27 of the back plate 22 is disposed so as to be inserted into the gap between the eaves gutter D and the nose cover C. The inner plate 3 is attached after the outer plate 2 is attached in this manner, but the inner plate 2 is arranged in contact with the inner peripheral surface so as to cover the joint of the eaves gutter D. 2 is disposed on the inner surface side of the portion to which the mounting projections 2 are attached, and the engagement projections 35 are moved over the engagement pieces 15b of the eaves gutter D so that the engagement projections 3
Press 5 and construct. At this time, the engagement projection 35 is disposed in a gap between the engagement piece 15b and the front plate 11 or the rear plate 12 (FIG. 4), and is reliably and easily engaged. Also, at the time of construction, if a sealing material 37 is applied to the dent on the back surface side of the protruding portion 36 and is pressed and fixed to the joint portion, there is no danger of water leakage. (Fig. 3)

After the inner plate 3 is attached, the front pressing piece 34 is disposed in contact with the lower surface of the engaging piece 15b of the eaves gutter D, and the rear pressing piece 34 is similarly engaged. Piece 15b
Contacted. That is, the front plate 31 is connected to the front plate 1 of the eave gutter D.
