Description

  The present invention relates to a simple building such as a terrace.

  As shown in FIG. 8, a conventional simple building such as a terrace has a front panel end face of a rafter 90 abutted against a rear side face of a girder 91 and is connected to a panel receiving portion 92 provided on the top face of the girder. A rainwater drainage groove (rain gutter) 94 for receiving rainwater from the roof panel is provided on the front side of the girder. The upper surface of the panel receiving portion 92 is a flat surface, and the rain water 95 that has flowed on the roof panel scatters forward from the panel receiving portion 92 and is received from the front end of the roof panel 93 in order to receive this rain water without leakage. It is necessary to increase the width W of the rainwater drainage groove 94 and raise the tip of the rainwater drainage groove 94 to substantially the same height as the tip of the roof panel 93 to minimize the height difference H from the top of the roof panel to the rainwater drainage groove. was there.

Patent Document 1 describes a structure in which the tip of a rafter is placed on a girder. When the rafters are placed on the top of the girder, the position of the roof panel rises, and accordingly, the rainwater drainage groove (rain gutter 22) extends further to the front of the girder and is higher than the top of the girder. It must be started up, and the width and height of the girders are increased, which is not preferable in appearance. In addition, since the rainwater drainage groove is provided in front of the roof panel, snow that slides on the roof panel is caught in the rainwater drainage groove in a snowy area, and the rainwater drainage groove may be deformed or damaged.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a simple building in which rainwater does not fall from the eaves even if the height difference from the roof panel tip to the rainwater drainage groove is increased.

In order to achieve the above object, a simple building according to the first aspect of the present invention includes a plurality of rafters, girders, and a roof panel, and the plurality of rafters are mounted and fixed on the upper surfaces of the girders. Has a rainwater drainage groove on the top surface and a panel receiving part between the rafters, the panel receiving part is located behind the rainwater draining groove and above the bottom surface of the rafter and upward and forward to the front corner part. The rainwater splash prevention part protrudes forward from the rear wall of the rainwater drainage groove, and the roof panel has a tip that is more than the rainwater splash prevention part of the panel receiving part. Is also mounted and fixed on the rear side.

The simple building according to the invention of claim 1 has a rafter mounted on the top surface of the girder and has a panel receiving portion between the rafters behind the rainwater drainage groove on the top surface of the girder. The height difference from the top of the roof panel to the rainwater drainage groove is increased by mounting and fixing the front end of the roof, but it has a rainwater scattering prevention part that bulges upward and forward at the front corner of the panel receiving part. Since the rainwater splash prevention part protrudes forward from the rear wall of the rainwater drainage groove, the rainwater flowing on the roof panel has a momentum of flow due to the upward swell of the rainwater splash prevention part. Once it is weakened , it flows inward along the rainwater splash prevention part and is guided to fall vertically toward the rainwater drainage groove, preventing rainwater from jumping over the rainwater drainage groove and falling from the eaves And drainage for rainwater It is possible to narrow the width.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 5 is a perspective view showing an embodiment of a simple building of the present invention, FIG. 2 is a longitudinal sectional view of the simple building, FIG. 3 is a cross-sectional view taken along line AA of FIG. It is BB sectional drawing of FIG. 2, FIG. 1 is a longitudinal cross-sectional view which expands and shows the eaves part of a roof. This simple building is a terrace installed in the garden of a house. As shown in FIG. 5, two right and left columns 8, 8 are erected in front of the housing 7 and connected to the upper ends of the columns 8, 8. And the girder 2 is installed horizontally, and the rafter 9 is attached to the housing 7, and a plurality of rafters 1, 1,... The roof panel 3 is attached between the rafters 1. The rafters 1 and the roof panel 3 are inclined so as to descend toward the front side.

The rafter 1 uses artificial wood obtained by extruding a synthetic resin mixed with wood powder. As shown in FIG. 4, the rafter 1 is formed in a hollow shape having a vertically long and substantially rectangular cross section. The cap 10 made of resin is attached to the tip. As shown in FIG. 2, the rear end portion of the rafter 1 is hung on a rafter hook 9 and fixed with screws 11 from below. On the front side of the rafter 1, the lower surface 1 a of the intermediate part is placed on the upper surface of the girder 2, and is fixed to the rafter placing piece 12 formed by protruding rearward from the upper surface of the girder 2 with screws 13 from below. A side surface of the rafter 1 and an upper surface of the girder 2 are fixed by a connecting metal fitting 14. The tip of the rafter 1 is located in front of the beam 2. In this way, the relatively long rafter 1 having a rectangular cross section is placed on the upper surface of the girder 2, and the front end of the rafter 1 protrudes in front of the girder 2, so that the roof has a pergola-like appearance.
As shown in FIG. 4, a concave portion 15 is formed in the longitudinal direction on the left and right side surfaces of the rafter 1, and a panel receiver 16 having a substantially L-shaped cross-section is attached so as to be embedded in the concave portion 15. The left and right ends of the roof panel 3 are placed on the panel receiver 16, and the panel holder 17 is attached to the upper surface of the panel receiver 16 to fix the roof panel 3. As shown in FIG. 2, the rear end portion of the roof panel 3 is inserted and held between upper and lower bead members 18 a and 18 b attached to the front surface of the rafter 9. A plurality of middle bars 19 are attached between the rafters 1 with a space in the front-rear direction, and the middle part of the roof panel 3 is received by the middle bars 19.

As shown in FIGS. 1 and 2, the girder 2 is constructed by attaching decorative covers 2b and 2c to the front and rear surfaces of a girder body 2a formed of an extruded aluminum material. On the front side of the girder body 2a, there is a rainwater drainage groove 5 that opens upward. Resin caps 20 are fitted to the left and right ends of the girder 2 to block the rainwater drainage grooves 5 and the small ends of the girder body 2a. A rainwater 21 provided along the column 8 is connected to the rainwater drainage groove 5, and rainwater collected in the rainwater drainage groove 5 is drained through the rainwater 21.
As shown in FIGS. 2 and 3, a panel receiving member 4 is attached to the upper surface of the girder 2 on the rear side of the rainwater drainage groove 5 between the rafters 1. As shown in FIG. 1, the panel receiving member 4 is formed in a hollow shape having a substantially square cross section, and has a panel pressing piece 22 and a support member 23 formed of rubber or the like on the upper surface. The front end portion of the roof panel 3 is inserted and held between the support members 23. At the front corner between the panel pressing piece 22 and the front wall 24, there is provided a rainwater scattering prevention portion 6 bulging upward and forward in an arc shape. The front wall 24 of the panel receiving member 4 and the rear wall 25 of the rainwater drainage groove 5 are continuous vertical surfaces.

The operation of the rainwater scattering prevention portion 6 of the panel receiving member 4 will be described with reference to FIG. The arrows in the figure indicate the flow of the rainwater 26. The rainwater 26 that has flowed on the roof panel 3 is temporarily weakened by the upward swell of the rainwater scattering prevention portion 6, and then the surface tension. It flows so as to be wound inward along the rainwater scattering prevention portion 6 swelled in an arc shape and falls vertically toward the rainwater drainage groove 5 below. In this way, the rainwater splash prevention unit 6 guides the rainwater 26 to fall vertically toward the rainwater drainage groove 5, so that even if the height difference H from the tip of the roof panel 3 to the rainwater drainage groove 5 is large, the rainwater 26 can be reliably prevented from jumping over the rainwater drainage groove 5 and falling from the front side of the girder 2, and the width W of the rainwater drainage groove 5 can be reduced, and the overall width of the girder 2 can also be reduced. In this way, the width W of the rainwater drainage groove 5 can be narrowed and arranged below the tip of the roof panel 3, so that the rainwater drainage groove 5 becomes inconspicuous and the eaves of the roof has a clean appearance. When the snow piled on the snow slides down, it becomes difficult to get caught in the rainwater drainage groove 5.
Furthermore, this simple building is formed by attaching a panel receiving member 4 that receives the tip of the roof panel 3 separately from the girder 2 to the upper surface of the girder between the rafters 1. Even when it is necessary to change the interval of the rafters 1 according to the situation of the place where the hanger is installed, it can be easily handled by cutting the panel receiving member 4 and changing the length.

  The present invention is not limited to the embodiments described above. The material and cross-sectional shape of the rafters and girders can be changed as appropriate. The rafters may be positioned at the same position as the front of the girders or behind the front of the girders. The rainwater scattering prevention part 6 of the panel receiving member may be formed so as to be able to prevent the rainwater scattering by temporarily weakening the momentum of the rainwater flowing on the roof panel, as shown in FIG. An R-shaped cross section that bulges upward only or, as shown in FIG. 6 (b), an inclined surface may be bulged upward and forward with a continuous polygonal cross section while bending inwardly. it can. Further, instead of attaching the panel receiving member 4 to the upper surface of the girder, the panel receiving portion can be integrally formed on the upper surface of the girder by extrusion molding. In that case, the panel receiving part is cut out only in the part where the rafter 1 is arranged. The roof is not limited to the one whose rear side is fixed to the housing, and as shown in FIG. 7, the rear side of the roof is also supported by the support 8 and can be an independent carport or shelter.
