Tighten with the hole 29a and nut 29b.

Middle purlin 31 supported by end rafters 9 and middle rafters 11
are both side walls 33 of an H-shaped cross-sectional main body 31a having a groove portion 32.
．． At the bottom end of 33, there is a seat piece 3 with an upwardly facing section and a face-down shape.
5 protruding outwardly, the proximal end 36 is protruded inwardly, and the lumber 37 is fitted into the groove 32, and the escape preventing edges 38, 38 of the lumber 37 are opposed to each other on both open side edges of the groove 32. It is formed.

The seat piece 35 of the middle main building 31 is fixed to the flat end projecting piece 24 of the end rafter 9 with bolts 39 and nuts 40, and to the earthen wall of the middle rafter 11 with screws 41, respectively.

Further, the end purlin 42 at the front end is a tubular body 42 having a square cross section.
A rain gutter part 43 is provided on top of the rain gutter part 43, and a groove part 44 at a height that joins to the lower surface of the upper end projection piece 22 of the end rafter 9 is provided adjacent to the rear of the rain gutter part 43.
Similarly, an upper end protrusion 22 is provided on the open rear edge of the rain gutter portion 43.
An upper connecting piece 45 having a height to be joined to the lower surface of the groove is provided to protrude forward, a piece of wood 46 is fitted into the groove 44, and escape prevention edges 47 of the piece of wood 46 are formed on both open edges of the groove 44 so as to face each other. ,
A piece 48 with a cross-section shaped like a cross is provided so as to protrude from the lower end of the rear side of the groove portion 44, and its tip faces toward the main body 42a side and joins to the upper surface of the intermediate projecting piece 23 of the end rafter 9. A lower connecting piece 49 is provided protrudingly at a height where it joins to the upper surface of the flat end projecting piece 24, and the space between the L-shaped piece 48 and the lower connecting piece 49 is formed as an insertion part 42b of the middle rafter 11. A drainage hole 50 for rainwater from the rain gutter section 43 is provided at both ends of the tubular body 42a vertically, and a hook-shaped metal fitting 51 is fixed to the inner surface of the rear wall of the drainage hole 50 portion. This is a hook for the rainwater conduction chain 52.

Regarding the connection between the end rafter 9 and the end purlin 42,
The front ends of the intermediate projecting piece 23 and the flat end projecting piece 24 of the end rafter 9 are cut out so that they can butt against the side surface of the end rafter 9, and the inner side wall 15 has cutout positions of the projecting pieces 23 and 24. niL
The shape connecting fittings 53 are fixed, a screw hole 55 is provided in the protruding piece 54, and a screw 56 passing through the rear wall of the end purlin 42 is screwed into the screw hole 55.゜2
4 and the upper and lower connecting pieces 45.49 of the end purlin 42 are connected at the joints with bolts 57.59 and nuts 58.60.

Next, to connect the end purlin 42 and the middle rafter 11, insert the front end of the middle rafter 11 into the insertion part 42a between the L-shaped piece 48 of the end purlin 42 and the lower connecting piece 49, and
The screw 61 that penetrates through is screwed into the lower wall of the middle rafter 11.

The corrugated plate 4 has its rear end inserted between the upper piece 2 of the rafter hanging 1 and the hanging piece 5 against the elasticity of the waterproof material 13 between them, and its side end hooked on the upper end protruding piece 22 of the end rafter 9. The front end is the end purlin 42
It is placed on the groove 44 of the upper connecting piece 45, and the front end edge is aligned with the front edge of the upper connecting piece 45, and is fixed onto the groove 44 of the middle purlin 31 and the end purlin 42 with nails 62 driven into the timbers 37 and 46.

In the figure, 63 is a cap that seals the front end of the end rafter 9, and 64 is a screw that fixes it.

Since the terrace according to this invention has the above-mentioned structure, when assembling it, first erect the supports 28 on the ground, fix the rafter hooks 1 to the house wall a with bolts 14, and then attach one member. You can connect them one by one, but you can easily assemble them as follows.

That is, after the roof part was assembled on the ground by connecting the rafters 9, 11 and the main building 31, 42, it was lifted and the hook fitting 25 at the rear end of the end rafter 9 was hooked to the lower piece 3 of the rafter hook 1. In this state, insert the post 28 into the insertion hole 30 at the front end of the end rafter 9, connect the end rafter 9 to the post 28 with the pole 29a and nut 29b, and then connect the end rafter 9 and the middle rafter 11 to the rear of each Connect the rafter 9 to the rafter hook 1 by inserting the end into the connecting fitting 10° 12 fixed to the rafter hook 1, and screwing the screw 19 passing through the side walls 15, 15' of the rafters 9, 11 into the screw hole 18. , 11 are concatenated.

After that, the corrugated sheet 4 is attached to the wood 37 of the middle purlin 31 and end purlin 42.
．． Nailed it to 46.

As described above, in the terrace of the present invention, the rafter hooks are formed into a substantially U-shaped cross section, and the ends of the rafters are fitted inside the U-shape, so that the ends of the rafters are completely covered by the rafter hooks. Rainwater running down the rafters will flow forward along the top surface of the rafters, preventing rainwater from entering the ends of the rafters, thus reliably preventing rainwater from leaking down the rafters inside the terrace. be able to.

In addition, the connection and fixation of the rafters and rafter hooks is done by fitting the end of the rafters into the rafter hooks, and by locking the hook fittings to the lower pieces with protrusions, so that the rafters can be attached to the top and bottom of the rafter hooks. This has the effect that the rafters can be firmly connected and fixed in a simple structure without coming off from between them.
