Description

[Detailed description of the invention] This invention relates to a building eave fitting that can be fixed to the tip of the rafters of a building's roof without using nails or bolts.

Conventional eaves fittings for buildings are long members having a surface portion, and upper and lower pieces extending rearward from the upper and lower ends of the surface portion, respectively, and having a substantially U-shaped cross section. To fix the tip of the rafter installed in the direction of the slope of the roof, insert the tip of the rafter into the opening between the top piece and the bottom piece, and use an electric drill to connect the top piece and the top surface of the rafter. A fastening hole must be drilled and a tapping screw or the like must be driven into the fastening hole.

Therefore, in order to fix conventional eaves fittings to the tips of rafters, workers must climb onto the roof, drill fixing holes for each rafter, and drive tapping bolts, etc. This requires considerable time and effort at the construction site, and the danger increases as power tools must be operated at high places.

Furthermore, since the eaves fittings are made of metal, shrinkage due to temperature changes is unavoidable. Therefore, when conventional eaves fittings are fixed to the rafters with tapping bolts, etc., the fixing holes may be damaged or the tapping bolts may come up, making it impossible to support the roof shingles after a long period of time. It may disappear.

Furthermore, with conventional eaves tips, rainwater can travel along the length of the eaves tips and infiltrate into the attic through the connecting portions, causing stains and corrosion on roof boards and the like.

This project was proposed in view of the above, and is a long metal eaves fitting that is fixed to the tip of each rafter installed in the direction of the roof's inclination, and the surface part that comes into contact with the tip of each rafter. A locking portion extending rearward is provided above the locking portion, a locking piece is provided by raising the rear end of the locking portion, and a receiving piece extending rearward is provided below the surface portion of the locking portion. An insertion part is provided facing the part and has an open rear surface between the locking part and the receiving part, and an upwardly bent piece is extended on the front surface of the surface part, and the bent part and the surface part a groove portion that is open at the top is formed between the bending piece, and an engagement piece that forms an engagement portion that is open at the bottom is provided in the bent piece in a forward direction, and the tip portion of the rafter is inserted into the insertion portion. In addition, a claw piece provided on the upper surface of the rafter is locked to the locking piece.

Hereinafter, the present invention will be explained with reference to the embodiments shown in the drawings. The eaves fitting 1 of the present building has a surface portion 3 that comes into contact with the end surface of a rafter 2 that is arranged parallel to the slope direction of the roof. . At the upper end of this surface portion 3, a locking portion 4 extending at a substantially right angle is provided facing rearward.
A receiving piece 6 is extended at the lower end of the surface portion 3 so as to face the locking portion 4, thereby forming an insertion portion having a substantially U-shaped cross section and opening rearward. Furthermore, a locking piece 7 is provided by raising the rear end of the locking portion 4 at a substantially right angle.

A bent piece 8 having a substantially L-shaped cross section is extended on the front surface of the surface portion 3. The base end of the bent piece 8 is located slightly below the upper end of the surface portion 3, and the bent piece 8
A shallow groove portion is formed between the surface portion 3 and the surface portion 3.

Further, an engaging piece 9 extending forward is provided at the upper end of the bent piece 8, and the distal end of the engaging piece 9 is bent downward to form an engaging portion 5 whose lower surface is open.

The eaves fitting 1 configured as described above can be manufactured integrally by extrusion molding, for example, aluminum.

On the other hand, the eaves fitting 1 as described above is attached to the rafters 2 to be fixed.
For example, as shown in FIG.
The lower end of 2a has outward facing flanges 2b, 2b. Further, a claw piece 10 is provided on the upper surface portion 2c near the tip of the rafter 2. The claw piece 10 stands obliquely forward from the upper surface portion 2c in a chevron shape, and its tip is bent downward. According to the embodiment shown in the drawings, the claw piece 10 is formed integrally with the rafter 2 by punching out the upper surface portion 2c, but it is formed separately and formed into the upper surface portion 2c.
It may be configured so that it is fixed with screws or the like.

On the rafters 2 as above, the eaves fitting 1 as above
In order to fix the roof, the insertion part of the eaves fitting 1 is attached to the tip of each rafter 2 arranged at appropriate intervals in the direction of the slope of the roof. That is, the tip part of the rafter 2 is inserted between the locking part 4 and the receiving part 6 of the eaves edge tool 1, and the rafter 2
The front end surface of the eave edge tool 1 is brought into contact with the back surface of the front surface part 3, and the claw piece 10 is attached to the locking piece 7 provided at the rear end of the locking part 4.
is locked, and this claw piece 10 is crushed by hitting it with a hammer or the like. Then, by carrying out the same operation on each rafter 2 and locking the claw pieces 10 and the locking pieces 7, the attachment of the eaves edge tool 1 is completed.

When roofing with shingles, the folded locking part 12 provided at the front end of the roof shingle 11 at the eaves is
The roof plate 1 is latched onto the engaging portion 5 of the eave edge tool 1.
You can start from 1 and put up the roof sheets one by one toward the ridge.

In this case, the eave edge fitting 1 is fixed to the rafter 2 by the claw pieces 10, so there is a degree of freedom for movement of the eave edge fitting 1 in the length direction, and the eave edge fitting 1 does not shrink due to temperature changes. Also, since it does not affect rafter 2,
The fixing hole will not widen and the tapping bolt will not be damaged. In addition, in the eaves fitting 1 of the present invention, a groove portion whose upper surface is open is formed between the locking portion 4 and the bending piece 8, and the locking piece 7 acts as a water return piece, so that in case of an accident, Even if rainwater infiltrates the lower surface of the roof board 11, the rainwater flows in the length direction of the eaves fitting 1 and is drained from the connection point between the eaves fittings 1 and 1, so that the roofing board etc. will not be stained or corroded. . Furthermore, since the eaves edge tool 1 can be fixed to the rafter 2 by simply tapping the claw pieces 10, there is no need to perform drilling work or bolt tightening work, making the construction easy and safe. Furthermore, the eave edge tool 1 not only covers the tip of the rafter 2 and effectively protects the rafter 2, but also can stably support the roof board.

FIG. 3 shows another embodiment of the present invention, in which the upper end of the bent piece 8 extends above the upper surface of the engaging portion 5 to form an upright support piece 13.
According to this embodiment, when the roof panel 11 is locked to the engaging portion 5, the roof panel 11 can be reinforced by supporting the roof panel 11 from below with the support pieces 13.

Note that the symbols not explained in FIG. 3 have the same configuration as the same symbols in the above-described embodiment, so the explanation will be omitted.
