[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for installing roof eaves, and more particularly to a structure effective for roof renovation.

[0002]

2. Description of the Related Art Conventionally, roofing materials such as a tile type, a slate type, and a metal type have been provided. In recent years, new roofing materials have been developed and used. This roofing material is superior in durability, sound insulation, heat insulation and the like as compared with conventional roofing materials, and has been adopted as a roofing material for a newly built house.
On the other hand, when a roof is renovated in an existing house, a demand for using a new roofing material as described above is increasing. When renovating a roof using new roofing material, there are two methods, one is to peel off the existing roofing material and construct a new roofing material, and the other is to construct a new roofing material from the existing roofing material There is a method, but the new roofing material is much lighter than the conventional one, and the construction period can be shortened.Moreover, considerable labor is required to peel off the existing roofing material. The method of constructing a new roofing material has been adopted.

[0003] When a new roofing material is installed from above without peeling off the existing roofing material, for example, as shown in FIG.
A new roofing material 2 is constructed on the existing roofing material 1 and a new eaves drain 3 is provided at the eaves of the new roofing material 2. The eaves drainer 3 is provided to extend below the existing eaves drainer 4 in order to prevent water from entering the existing roof portion. In addition, the code | symbol 5 in a figure is tarki,
Reference numeral 6 denotes a fascia, 7 denotes a field board, and 8 denotes Hiroko Mai.

[0004]

However, as described above, when a new roofing material 2 is constructed on an existing roofing material 1 as described above, the eaves of the existing roofing material 1 is replaced with the new roofing material 2.
As the roof surface rises when covered, the water that flows out of the eaves of the new roof flows out ahead of the water that flows from the eaves of the existing roof and protrudes from the existing gutter 9, as shown in the figure. In addition, the gutter 9 must be moved forward and re-attached, which requires a great deal of labor. Especially,
When the existing roof is a tile-bar type, the surface has an uneven shape and it is difficult to construct a new roof, so the plywood 10 is provided on the surface of the existing roofing material 1.
This further increases the roof surface, and the work of reattaching the gutter 9 becomes difficult.

The present invention has been made in view of the above circumstances, and in the case of constructing a new roofing material on an existing roofing material, the water flowing from the eaves of the new roof is allowed to flow into the existing gutter. The purpose is to provide an eaves-first-payment structure to attach eaves drainers.

[0006]

In order to achieve the above-mentioned object, the present invention provides a structure for storing eaves at the eaves end, wherein the eaves drainer is mounted on an upper surface of an existing roofing material. And a draining plate hanging downward from the edge of the plate, and integrally formed with an extruded material, and a hook portion bent toward the eaves side is integrally formed on the mounting plate, and Part is locked to the lower side of the new roofing material ,
The edge of the new roofing material is almost directly above the edge of the existing roofing material
Is located slightly inside the edge of the existing roofing material
And the draining board is located near the edge of the new roofing material.
It extends directly below and reaches the lower edge of the edge of the existing roofing material.
Water flowing from the new roofing material
It is designed to fall along the board .

According to a second aspect of the present invention, in the first aspect, the joint portion is formed along the longitudinal direction of the eaves at the eaves drain, and the eaves drains are abutted with their end faces facing the joints. A connecting pin is inserted into a joint portion to be formed, and the eaves drains are connected.

According to a third aspect of the present invention, in the second aspect, a waterproof sheet is adhered to the back surface of the junction between the eaves drains.

[0009]

[Function] In the eaves front storage structure of claim 1, the water flowing out of the eaves of the new roofing material travels along the eaves drainage and falls along the same locus as the water flowing out of the existing roof eaves and falling. As a result, there is no need to reattach the gutter because it surely flows into the existing gutter. Further, by forming the eaves drainer with an extruded member as a simple structure including the mounting plate and the drainer plate, the eaves drainer can be easily manufactured. In addition, the eaves drainage mounting plate is attached to the upper surface of the existing roofing material, and the hook is locked to the lower side of the new roofing material, completely closing the gap between the existing roofing material and the new roofing material, Prevent rain leakage from this period.

[0010] In the eaves front filling structure according to the second aspect, the end faces of the eaves drains are butted with the joints facing each other, and the eaves drains are joined by inserting the joining pins into the opposed joints. Position and join the eaves drains easily and reliably.

According to the third aspect of the present invention, there is provided a joint structure in a case where the eaves drains are joined with their end faces abutted by attaching a waterproof sheet to the back side of the joints of the eaves drains. Prevent rain leakage in the area.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an embodiment of the present invention; FIG. FIG. 1 is a side sectional view of a roof eave. In the eaves part of the existing roof in this figure, a blindfolding material 6 is fixed to the tip of the eaves of the tarki 5 and a base plate 7 is put on the tarki 5. The basic configuration is such that a small dance 8 is added, and a wide eaves drain 4 formed by bending a thin plate is attached to the wide small dance 8, and a roofing material 1 of a tile bar type is provided on the upper surface of a field base plate 7.

As shown in FIGS. 1 and 2, a plywood 1 for covering unevenness on the surface of the existing roofing material 1 is provided.
0 is placed, and the nail 11 is removed from the plywood 10 to the existing roofing material 1,
It is fixed by driving the corewood 12 and the base plate 7 into the tark 5 and driving it onto the plywood 10.
0 is constructed by the horizontal roofing method. This new roofing material 2
Reference numeral 0 denotes a structure in which a large number of aluminum alloy plate members 21 are connected over the entire roof, and the upper and lower water gradient ends of each plate member 21 have plate members 21 vertically adjacent to each other. The bent portions 21a and 21b which engage with each other are formed to extend in the width direction of the plate body 21 (the direction orthogonal to the plane of FIG. 1). The edge of the new roofing material 20 below the water gradient, that is, the plate body 21 located on the eaves side, is disposed inside (the right side in FIG. 1) the edge of the existing roofing material 1. An eaves drain 22 is provided between 21 and the existing roofing material 1.

The eaves drainer 22 is mainly composed of a mounting plate 23 mounted on the upper surface of the plywood 10 and a draining plate 24 hanging downward from the left edge of the mounting plate 23, and is made of an extruded material such as aluminum. It is formed integrally. A hook 23a that is bent toward the eaves side is formed integrally with the mounting plate 23. The hook 23a is attached to the mounting plate 23.
1 extends in the longitudinal direction (in the direction perpendicular to the plane of FIG. 1), the bent portion 21a of the plate 21 is locked,
This prevents water from entering between the existing roofing material 1 and the new roofing material 20. The mounting plate 23 has an edge protruding slightly forward from the plywood 10 and abutting on the plywood 10, and is fixed to the plywood 10 by a nail 25. Further, a roofing 26 is provided on the upper surface of the plywood 10 to prevent a slight rain leak from the roof surface, and the roofing 26 is fixed to the plywood 10,
Its tip extends to the hook 23a. Further, in the embodiment, a water receiving plate 21c is laid between the plate body 21 and the roofing 26, and the bent portion 21d at the lower end of the water gradient is locked and fixed to the hook portion 23a.

The drain plate 24 is a vertical plate 24a extending vertically downward from the edge of the mounting plate 23, and a parallel plate 24b extending downward from the lower edge of the vertical plate 24a in parallel with the end surface 1a of the existing roofing material 1. And the parallel plate 24
b is located slightly ahead of the existing eaves drain 4 and its lower edge is set to be substantially the same height as the lower edge of the existing eaves drain 4. Also, on the back side of the joint between the drain plate 24 and the mounting plate 23 and on the back side of the lower edge of the drain plate 24,
A joint portion 30 extending in the eaves longitudinal direction (the direction perpendicular to the paper surface in FIG. 1) is integrally formed. The joint portion 30 has a ring-opened cylindrical shape, and can be integrally formed simultaneously and easily when the eaves drainer 22 is extruded. A large number of eaves drainers 22 are joined in the longitudinal direction of the eaves tip. As shown in FIG. 3, the eaves drainers 22 are joined with the end faces of the eaves drainers 22 so that the joints 30 are opposed to each other. 30,
This is performed by inserting a joining pin 31 through the connector 30.

As shown in FIGS. 3 and 4, the joining pin 31 is composed of a cylindrical pin body 32 and a knurled portion 33 formed at the axial center of the pin body 32. The diameter of 31 is the joint 30
And the diameter of the knurled portion 33 is formed slightly larger than the inner diameter of the joint portion 30. When the joining pin 31 is inserted into the joints 30 facing each other, one joint 3
0 and one side of the pin body 32
3 is pushed in by a hammer or the like, and thereafter, the other side of the pin body 32 is inserted into the other joint portion 30. In this case, as shown in FIG. 5, the knurled portion 33 is pressed against the inner wall surface of the joint portion 30 and is securely fixed, whereby the joining pin 31 is positioned and fixed at the joint portion 30.

In this way, by joining the eaves drainer 22 with the joint portion 30 and the joining pin 31, the eaves drainer can be positioned and joined easily and reliably, and the joining pin 31 is connected to one of the two pins. Since the knurled portion 33 is inserted through the joint portion 30 and the other side of the pin body 32 is inserted through the other joint portion 30, the insertion length of the joining pin 31 inserted into the joint portion 30 is reduced to the eaves drainage. Is constant at each of the joints, and more reliable joining can be achieved, and there is no large gap in the joint surface between the eaves drainers 22. Also,
Since the joint portion 30 is extruded simultaneously with the extrusion of the eaves drainer 22, the joint portion 30 is
2 extend in the longitudinal direction, so that the eaves drainer 22 can be reinforced.

Further, a waterproof sheet 35 is attached to the back surface of the junction between the eaves drainers 22, as shown in FIGS. This waterproof sheet 35 is
It is made by foaming an admixture of synthetic rubber EPDM, and is excellent in weather resistance, cold heat resistance, chemical resistance, etc., and has elasticity, so that it is suitable for waterproofing gaps with rough surfaces. By adhering such a waterproof sheet 35 to the joint, it is possible to reliably prevent rain leakage at the joint, and furthermore, when joining the eaves drainers 22, the expansion and contraction of the eaves drainer itself due to a temperature change is prevented. In consideration of this, even if the waterproof sheet 35 is joined with a slight gap, the waterproof sheet 35 expands and contracts in accordance with the expansion and contraction of the eaves drainer itself, so that it is possible to reliably prevent rain leakage at the joint.

FIG.
As shown in (2), water flowing from the eaves of the new roofing material 20 falls down along the eaves drain 22. Since the edge of the new roofing material 20 is disposed inside the edge of the existing roofing material 1, the water falling down along the eaves drainage flows out from the eaves of the existing roof. It falls along the same locus as the falling water and flows into the existing gutter 9 reliably. Therefore, a new roofing material 2 is placed on the existing roofing material 1.
It is not necessary to reattach the gutter 9 when renovating the roof on which the construction No. 0 is constructed, so that the cost required for renovation can be reduced.

Further, a simple structure comprising a mounting plate 23 for mounting the eaves drainer 22 on the upper surface of the existing roofing material 1 via the plywood 10, and a drainer plate 24 hanging downward from the edge of the mounting plate 23. And, since it was formed with an extrusion die,
The eaves drainer 22 can be easily manufactured, and in this respect, the cost required for renovation can be reduced.

Further, a mounting plate 23 of the eaves drainer 22 is mounted on the upper surface of the existing roofing material 1, and a hook formed by bending the mounting plate 23 toward the eaves side is formed with a new roofing material 20. Since it is locked to the lower surface side, the space between the existing roofing material 1 and the new roofing material 20 is completely closed, and it is possible to reliably prevent rain leakage from this space.

FIG. 6 shows a modification of eaves drainage. The eaves drainer 36 shown in this figure differs from the eaves drainer 22 in the mounting position of the joint 30. That is, in the eaves drainer 36, one of the two joint portions 30 is formed behind the hook portion 23 a on the upper surface of the mounting plate 23. When the joint portion 30 is formed in such a position, the distance between the joint portions is longer than that in the case of the above-mentioned eaves drainage 22, so that the joining rigidity is improved. There is an advantage that the waterproof sheet 35 can be easily installed and the waterproofing ability can be further increased since there is only one joint portion 30 and the other portions are flat without protrusions.
