Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an eave structure for a horizontal roof.

<Prior Art> As is well known, when a roof is laterally roofed, the front end of the roof board located at the tip of the eaves must be fixed to the eaves member.

Conventionally, the eave edge member was fixed to the tip of the rafter, and the tip of the roof board material was latched and fixed to the eave edge member.

<Problems to be Solved by the Invention> However, nails and screws are used to fix the eave end members to the ends of the rafters, which is extremely troublesome.Moreover, if the positions of the horizontal rafters are even slightly shifted, the eave end members may need to be fixed. They cannot be fixed in place, and it is extremely time-consuming to remove the eave members when repairing the roof.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes providing supports at the ends of the eaves of a plurality of rafters extending from the ridge toward the eaves. This is characterized in that an eaves edge member is fitted and fixed to the eaves edge member, and the tip of the horizontal roofing board material is locked to the eaves edge member.

<Embodiments> The present invention will be described below with reference to the illustrated embodiments. FIG. 1 shows a rafter 1, a support 2 fixed to the rafter 1, and an eaves member 3 fitted and fixed to the support 2. FIG. The rafter 1 is made of a metal material, and includes an upper surface portion 4, left and right side portions 5, 5 extending downward from the left and right side edges of the upper surface portion 4, and outwardly extending from the lower edge of each side portion 5. It has an extending flange 6, and a plurality of these are installed in parallel from the ridge of the roof toward the eaves.

A support portion 7 for fixing the support 2 is provided at the tip of the eaves of the rafter 1 described above. In the embodiment shown in the drawings, the support part 7 has two front and rear claw pieces 8, 8 cut upright from the tip of the upper surface part 4, and these claw pieces 8 allow the support 2 to be attached to the eaves of the rafter 1. It is fixed to the tip.

On the other hand, the support 2 attached to each rafter 1 is provided with a short upper plate 10 at the rear at the upper end of the front plate 9, and a lower plate 11 which is parallel to the upper plate 10 and longer than the upper plate 10 at the lower end of the front plate 9. The upper surface plate 10 and the lower surface plate 11 each have a U-shaped cross section, and a locking portion 12 that slightly protrudes upward or downward is provided in a protruding manner. This locking portion 12 gradually becomes higher from the front end toward the rear end, and the rear end surface is vertical. Further, at a position rearward of the locking portion 12 of the lower plate 11, a locking claw piece 13 extending rearward and downward, and front and rear holes 14, 14 through which the claw piece 8 described above passes are provided.

The eaves member 3 to be fitted and fixed to the above-mentioned support 2 is a long material extruded from aluminum or the like, and has a fixing part 16 for roofing board material extending rearward from the upper end of the surface part 15. A receiving piece 17 extending forward is formed inside the fastening part 16. An upper support plate 18 and a lower support plate 19 extending rearward are provided above and below the surface portion 15.
A fixing cavity 20 for the support 2 is formed on the rear surface, in a portion surrounded by the lower surface of the support plate 18 and the upper surface of the lower support plate 19 and open at the rear. Note that the support plate 18 and the lower support plate 19 are provided with shallow groove-shaped receiving portions 21 that protrude upward or downward.

The roof board material 22 used in the present invention is for horizontal roofing, and has a locking part 23 that bends downward at the front end, and an engaging part (not shown) that engages with the locking part 23 at the rear end. It was established.

In order to construct the eave portion of a roof using the rafters 1, supports 2, eaves member 3, and roof board material 22 described above, as shown in FIG.
The rafters 1 are mounted and fixed on the upper surface of the heat insulating material 25 laid on top, and the supports 2 are attached to the tips of each rafter 1. To attach the support 2 to the tip of the rafter 1, place the support 2 on the upper surface 4 of the rafter 1, lock the locking claw pieces 13 to the tip of the upper surface 4, and insert each claw 8 into the hole 1.
4 from below, and hit the claw piece 8 protruding from the upper surface of the lower plate 11 with a hammer or the like to bring it down to the upper surface of the lower plate 11. As a result, the support 2 is firmly fixed to the upper surface of the rafter 1, but if necessary, the lower surface plate 11 and the upper surface portion 4 may be fixed with screws or the like.

After the supports 2 are fixed to the tip of each rafter 1 in this way, the eaves member 3 is fitted and fixed to each support 2 in series from the front end. In this case, the support 2 is fitted into the fixing cavity 20 of the eaves edge member 3, but the elasticity of the metal support plate 18 and lower support plate 19,
Using the elasticity of the top plate 10 and the bottom plate 11, the support 2 is forcefully fitted into the rear opening end of the fastening cavity 20, and the locking parts 12 of the top plate 10 and the bottom plate 11 are attached to the bottom surface of the support plate 18. and the upper surface of the lower support plate 19 while fitting and locking into each receiving part 21.

Therefore, each locking portion 12 is fitted into the receiving portion 21, so that the eaves member 3 is firmly supported without moving in the front-rear direction. Note that, if necessary, the eaves edge member 3 may be fixed by driving screws or the like into the contact portion between the support 2 and the eave edge member 3.

After the eaves edge member 3 is fixed in this way, the locking part 23 of the roof board material 22 located at the tip of the eaves side is hooked onto the fastening part 16 of the eave end member 3, and the roof board material 2
Fix the rear end of 2 with a hanger, etc.

If necessary, a decorative board 25 is attached to the surface of the eaves edge member 3, a hook portion 26 formed at the upper edge of the decorative board 25 is locked to the receiving piece 17, and a bent part formed at the lower end of the decorative board 25 is attached. The portion 27 is folded upward and fixed at the lower end of the surface portion 15. Also, the fascia material 28 is applied to the lower part of the eaves member 3 to finish.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments described above, and can be practiced with any modifications within the scope of the claims. can do.
For example, the support 2 may be attached to the rafter 1 in advance and then the rafter 1 may be fixed to the main building or the like, or the support 2 may have a different configuration. Further, the rafter 1 and the support 2 are not fixed by the claw pieces 8, but may be of other configurations.

<Effects of the Invention> In short, according to the present invention, since the eave end member is fixed by the support provided on the rafter, the installation of the eave end member becomes extremely easy and the construction work becomes quick. By slightly adjusting the fixing position of the support, even if the rafter is slightly out of position, it can be easily fixed without forcibly bending the eaves edge member, which is of extremely high practical value.
