Description

[Detailed Description of the Invention] The present invention relates to a roof of a balcony, terrace, etc., which has a front frame for reinforcing the eaves.

Conventionally, the roofs of balconies, terraces, etc., where corrugated roof sheets were installed by extending outward from the outside wall of the house using a support structure, were fixed to the top surface of a base structure made up of rafters and a main building. One end of the rafters of the frame is fixed to a rafter hook provided on the wall surface, and the other end on the eaves side is supported by a support via a support or beam,
The front edges of the corrugated roof panels and the ends of the rafters are covered and fixed to the front frame, which doubles as rain gutters and provides reinforcement and beauty.

In the conventional front frame, a shaped material having a cross-sectional shape as shown in FIG. A rain gutter 20' supports the lower surface of the corrugated roof sheet 3 shown by the dashed line between the rain gutter 20' and the rear wall, and a protruding edge 15' of the upper wall is attached to the upper surface of the rain gutter 20'. The front edge of the roof sheet was held by covering the upper surface of the front edge of the roof sheet.

Roofs with conventional front frames like this can be used without any problems as long as an excessive load is not applied to the top surface of the roof, but when there is a large amount of snow, especially in cold regions, Due to the accumulation of snow with a large moisture content at the eaves tip, or the so-called ice embankment formed by freezing and growing, an excessive weight of up to 500 kg may be applied to each meter of eave width, causing the eave tip of the roof board 3 to bend and deform downward. The deformation stress affects the fixation of the roof sheet itself, causing problems such as bending and cracking of the roof sheet, and in extreme cases, leading edge breakage.

The present invention solves the above-mentioned problems by reliably holding the edge of the eave of the corrugated roof plate from the upper and lower surfaces, and in combination with supporting the lower surface by the upper edge of the rear wall of the rain gutter or by the main building. To provide a roof having a front frame reinforced eave part that has sufficient pressure resistance and good drainage performance even against excessive loads.

The embodiments shown in the drawings will be explained below.

Figure 1 is a partially cutaway perspective view of a veranda roof, Figure 2 is a side view of the front frame in cross section and also shows the connection with the roof frame, and Figure 3 is a perspective view of the front frame. It is.

In the drawing, the front frame 1 is fixed to two ends of the rafters at the front edge of the eaves of a roof structure composed of rafters 2, a purlin 4, and a corrugated roof plate 3, and the other end of the rafters 2 is fixed to the outside wall W of the house. The rafters 2 are suspended and fixed to the rafters 8, and the eaves side of the rafters 2 is supported by supports 7 to install a roof. 6 is a side frame.

The front frame 1 includes a front wall 11 and a rear wall 1, each having a reinforced wave front.
2. A bottom plate 17 having a hollow body 10 consisting of a bottom wall 13 and a top wall 15, and protruding from the rear wall 12.
A rain gutter 20 made of a trailing edge plate 18 is integrally formed, and the upper edge 19 of the trailing edge plate 18 is a narrow edge for supporting the lower surface of the roof plate. At one end of the upper part of the hollow main body 10, there is a corrugated plate insertion part 16 which is approximately parallel to the upper wall 15 of the hollow main body following the rain gutter 20 and has a spacing below which the front edge of the corrugated roof plate 3 is inserted and held. A partition wall 14 is provided. The bottom plate 17 of the rain gutter 20 has a protruding edge 21 extending outward from the rear edge plate 18, and is attached to the rear wall 12 of the front frame 1 and the upper surface of the rafter 2 at the tip of the eave of the rafter 2 shown by the dashed line in FIG. The bottom plate 17 is brought into contact with the front frame 1, and the front frame 1 is fixed by screws at the projecting edge 21.

Reference numeral 22 denotes an angle for fixing the side frame, which is fixed inside the frame end of the hollow main body 10 of the front frame 1.

The rear edge of the corrugated roof sheet 3 is suspended by the rafter hanger 8, the front edge is inserted and held in the corrugated sheet insertion part 16 of the front frame 1, and the corrugated sheet roof sheet 3 is fixed to the main building 4 with a fixing screw 5 in the middle. However, the front edge 30 of the corrugated roof sheet 3
is installed so as to be spaced apart from the bottom wall 16' of the corrugated plate insertion part 16.

With the above configuration, the front edge of the corrugated roof plate 3 is inserted into the corrugated plate insertion part 16 of the front frame 1 having the hollow body 10 with high strength, and the upper edge 1 of the rear edge plate of the rain gutter 20
9 supports the lower surface of the board, a reinforced eave part that can withstand a large load is obtained, and the front edge 30 is located away from the bottom wall 16' of the corrugated sheet insertion part 16, so that the corrugated sheet roof sheet 3 is inserted, the rainwater flowing down the three surfaces of the corrugated sheet roof plate and flowing into the corrugated sheet fitting part 16 is smoothly discharged into the rain gutter 20 through the space on the lower surface of the corrugated sheet.

Although one embodiment has been described in detail above, the corrugated plate insertion part 16 of this invention does not necessarily need to be formed on the upper part of the hollow body 10, but in front of the corrugated plate roof plate 3 as shown in FIG. A recess may be formed on the rear wall 12 of one side end of the hollow portion 10 in the front frame 1 corresponding to the edge.

Further, as shown in FIG. 5, the corrugated roof sheet 3
is supported by the purlin 4 and the corrugated plate insertion part 16, so the upper edge 19 of the trailing edge plate 18 of the rain gutter does not necessarily need to contact and support the lower surface of the corrugated plate 3, and even if there is a slight gap, There is no problem.

As described above, in the roof of the present invention, the front edge of the corrugated roof plate fixed to the base frame consisting of the rafters and the purlin is held at the upper and lower surfaces by the upper corrugated plate insertion part of the front frame. Even when a large load is applied to the roof plate, a sufficiently reinforced eave area is obtained to prevent the tip edge of the roof plate from bowing downward, and rainwater flowing down the surface of the corrugated plate roof plate is smoothly channeled through the corrugated plate insertion part. Since rainwater does not flow into the rain gutter and overflow from the eaves, it can be particularly suitable as a roof for cold and snowy regions.
