In addition, two purlins 5, 5 are bridged between the adjacent rafters 4, 4, respectively.

[0010] With respect to the hut set thus constructed, a front frame 3 and a rafter 2 and each of the adjacent rafters 4 and 4 are divided into a long area in the front-rear direction and a roof made of an acrylic plate or the like. Thatch 6 is attached to each. The front frame 3 also serves as a rain gutter, and reference numeral 7 in the figure denotes a vertical gutter that guides rainfall on the balcony roof 1 to the ground surface via the front frame 3.

Next, the attachment structure of the purlin 5 to the rafter 4 will be described in detail with reference to FIG. As shown in the figure, a bracket (connecting material) 8 is fixed to the side of the rafter 4 at a mounting position of the purlin 5, and each end of the purlin 5 is attached to the rafter 4 via the bracket 8. I have. The purlin 5 has a hollow portion 11, and each end of the purlin 5 is abutted against the side surface of the rafter 4 so as to insert the bracket 8 into the hollow portion 11, and in this state, the rear side wall 12 of the bracket 8 is provided.
It is fixed to. When the purlin 5 is assembled into the rafter 4, the bracket 8 is attached to the purlin 5 as shown in FIG.
Completely concealed in the hollow portion 11.

The bracket 8 is formed by bending a thick steel plate, a stainless steel plate or the like into an “L” shape. The short side portion 21 is fixed to the rafter 4 in a horizontal state, and the purlin 5 is attached to the long side portion 22. Fixed. In the short side portion 21 of the bracket 8, a through hole 24 for a fixing screw 23 is formed at the center thereof, and a pair of upper and lower detents 2 are formed on the surface on the rafter 4 side.

A screw hole 26 for a fixing screw 13 for fixing the purlin 5 is formed in the long side portion 22 of the bracket 8 at the front end side, and the fixing screw 13 connects the rear side wall 12 of the purlin 5 from outside. It penetrates and is screwed into this screw hole 26.
In this case, the long side 22 of the bracket 8 fits between the upper wall 14 and the lower wall 15 of the purlin 5, and the purlin 5 is
And is fixed immovably by one fixing screw 13. The through hole 24 and the screw hole 26 are arranged on the center line of the bracket 8 in the height direction, and the pair of rotation stopping projections 25 are arranged symmetrically with respect to this center line. The left and right brackets 8 can be shared.

On the other hand, the purlin 5 is formed in a hollow shape as described above, and a mounting portion 16 having a C-shaped cross section for mounting a cushioning material (not shown) is formed on an upper surface of an upper wall 14 thereof. Have been. The cushioning material mounted on the mounting portion 16 presses the roofing material 6 lightly from below, thereby
Prevents rattling. On the lower surface of the upper wall 14, a pair of protruding pieces 17a, 17b are formed so as to protrude into the hollow portion 11 at symmetrical positions in the front-rear direction. The gap between the rear protruding piece 17 a and the rear side wall (inner side surface) 12 is formed slightly wider than the thickness of the long side portion 22 of the bracket 8, and this portion is formed by the length of the bracket 8. The engaging portion 18 is engaged with the side portion 22 (details will be described later).

Further, at the end of the purlin 5, an upper wall 14 is provided.
A notch 19 is formed in the bracket 8 to allow relative loose insertion from above the bracket 8. The notch 19 includes a wide portion 19 a corresponding to the short side 21 of the bracket 8 and a narrow portion 19 b corresponding to the long side 22 of the bracket 8. The wide portion 19a and the narrow portion 19b are formed symmetrically with respect to the center line of the purlin 5 in the front-rear direction,
The left and right ends of the purlin 5 have the same shape.

Next, referring to FIG. 2B and FIG.
A procedure for attaching the purlin 5 to the rafter 4 will be described. First,
A bracket 8 is fixed to each of the right and left rafters 4 to which the purlin 5 is attached. In this case, the left and right brackets 8
In each case, the long side portion 22 is fixed so as to be located rearward, that is, to be located on the upstream side of the roof slope. Of course, the rafter 4 may be assembled after the bracket 8 is attached. Next, holding the purlin 5 in hand, aligning the notch 19 with the bracket 8,
The purlin 5 is attached to the bracket 8 from below (FIG. 3A)
And FIG. 3 (b)).

At this time, the bracket 8 is placed in the hollow portion 11 of the purlin 5 and the purlin 5 is pushed up until the lower wall 15 of the purlin 5 contacts the lower end of the bracket 8. Is moved to the front until it touches, and in this state, the hand is released from the purlin 5. When the player releases the purlin 5, the purlin 5 moves slightly downward with the rear side wall 12 as a guide, and is temporarily placed on the bracket 8 (FIG. 3C). At this time, the upper end of the long side portion 22 of the bracket 8 is engaged with the engaging portion 18 formed between the projecting piece 17 a of the purlin 5 and the rear side wall 12. That is, the purlin 5 is temporarily placed on the left and right brackets 8 such that the long side portion 22 of the bracket 8 is sandwiched between the protruding piece 17 a and the rear side wall 12. Finally, the purlin 5 is pressed against the bracket 8, and the fixing screw 13 is screwed in (FIG. 3D).
As an efficient work procedure, all the purlins 5 are temporarily placed on the bracket 8, and then the fixing screws 13 are attached. On the other hand, when the roofing material 6 is damaged and replaced, the purlin 5 is detached from the rafter 4 in the reverse procedure.

The above procedure for attaching the purlin 5 is based on the premise that an assembling method in which all the rafters 4 are incorporated before the purlin 5 is incorporated is adopted. However, if the attachment structure of the purlin 5 of the embodiment is used, for example, after assembling the rafters 2 and the front frame 3, the respective components are sequentially assembled in the left-right direction in the order of the rafters 4, the purlin 5 and the roofing material 6. The assembling method becomes possible. In such a case, the main building 5 is temporarily placed on the rafter 4, the roofing material 6 is assembled, and after the next rafter 4 is assembled, both ends of the main building 5 are fixed permanently.

In this case, the purlin 5 is temporarily placed on the rafter 4 in a cantilever state. As described above, the purlin 5 is stably held by the bracket 8 fixed to the rafter 4, so that When assembling the material 6, there is no problem such as the purlin 5 falling off from the bracket 8. When this assembling method is performed, it is preferable that the long side portion 22 of the bracket 8 is formed sufficiently long or that a tongue piece can be attached as an attachment.

As described above, according to the present embodiment, since the notch 19 into which the bracket 8 can be inserted is formed in the purlin 5, the purlin 5 can be easily attached from below to the rafter 4 to which the bracket 8 is attached. can do. Further, since the engaging portion 18 connected to the notch portion 19 is formed in the purlin 5, the purlin 5 can be temporarily stably placed on the bracket 8, and the purlin 5 can be fixed to the bracket 8 in this state. ,
Attachment of the purlin 5 to the rafter 4 can be performed simply and by one worker. That is, the work of attaching or detaching the purlin 5 can be performed extremely easily and safely. Moreover, the present invention is also suitable for a method of assembling the balcony roof 1 in which the purlin 5 is incorporated into the rafter 4 in a cantilever manner.

FIG. 4 shows a second embodiment of the present invention. As shown in the figure, in this embodiment, a pair of folded pieces 22a, 22a slightly bent inward are formed at the upper and lower ends of the long side 22 of the bracket 8. The purlin 5 is formed in a cross-sectional shape in which the protruding pieces 17a and 17b are omitted. In this case, the folded piece portions 22a, 2
The vertical length of the long side portion 22 including 2a is formed so as to be slightly longer than the vertical length of the hollow portion 11 of the purlin 5, and as shown in FIG. When the bracket 8 is engaged with the engaging portion 18 of the purlin 5 by laterally moving it toward the front, the folded pieces 22a, 22a slightly bend, and the bracket 8 presses the purlin 5 in the vertical direction.

As a result, the purlin 5 is firmly engaged with the bracket 8, and the purlin 5 is almost temporarily fixed. In this state, even if vibration or light impact acts on the purlin 5, the main roof 5 does not fall off the rafter 4, and the above-mentioned purlin 5 is incorporated into the rafter 4 in a cantilever state. Particularly suitable for an assembling method.

In the above embodiment, the connecting material is
The "L" shaped bracket is used sideways,
The shape and structure of the connecting member are arbitrary as long as the connecting member can be loosely inserted into the purlin and the purlin can be temporarily placed (and fixed). In addition, the locking portion formed on the purlin may be such that the purlin can be temporarily placed on the bracket, and the protrusion may be omitted.

[0024]

As described above, according to the shingle with a simple roof according to the first aspect, the purlin material can be assembled to the hanging lumber from below, and the purlin material can be temporarily placed on the connecting material. Therefore, the assembling work of the purlin can be performed extremely easily and safely. Further, not only the assembling but also the removal of the purlin can be easily and safely performed in the reverse procedure.
