Description

[Detailed Description of the Invention] Target of the Invention The present invention relates to a structure for taking in skylights from the roof.

Conventional Example As shown in FIG. 1, by providing a horizontal lighting window 2 on a roof 1, skylights can be guided to the attic without worrying about rain leaks.

However, since this part would protrude more than the other parts, it was necessary to make it strong enough to receive crosswinds and to be structurally strong.

Purpose of the invention The purpose of the invention is to provide a new skylight intake structure that can sufficiently withstand crosswinds.

Structure of the invention In this invention, the lower chord of a triangular truss that protrudes above the roof is fixed to the roof frame, and the upper chord of the triangular truss is also protruded further outward than the vertical belly members of the outer ends of the triangular truss. In addition to composing the eaves,
A lighting window is provided in the above-mentioned body part.

Embodiment In FIG. 2, 3a and 3b are a pair of symmetrical right triangular trusses constituting the roof frame 4, and each of the lower chord members 5a and 5b is arranged in a straight line in the horizontal plane, and the upper chord members 3a and 3b are arranged in a straight line in the horizontal plane. 6a and 6b are provided so as to be inclined in opposite directions.

Thus, 7 is an isosceles triangular truss attached to one side of the right triangular truss 3a. That is, the lower chord member 8a of this isosceles triangular truss 7 is
The upper chord member 6a of the right triangular truss 3a is fixed by appropriate means near the upper end, and the upper chord member 8b is also arranged in the extending direction of the upper chord member 6b of the remaining right triangular truss 3b.

9 is the upper and lower chord members 8 of the isosceles triangular truss 7.
This is the belly material that is passed vertically at positions equidistant from b and 8a. And, as shown in Figure 3, 10 is
This is an eaves angle that is attached vertically to the tip of the top chord member 8b that projects outward from the belly member 9 via a substantially triangular gusset plate 11. 12 is a fascia base plate attached to this eave angle 10. 13 is a fascia plate attached to the outer wall surface of this fascia base plate 12. Reference numeral 14 designates a reinforcing plate extending along the upper chord 8b between the gusset plate 11 and a rectangular gusset plate 15 that joins the belly member 9 and the upper chord 8b.

Reference numeral 16 in FIG. 3 is an attic edge extending along the fascia base plate 12 at the lower end of the eaves angle 10, and this attic edge 16 and the belly material 9
A field edge 17 extends horizontally between the upper end and the vicinity thereof. Reference numeral 18 denotes an eave board attached to the lower surface of the eaves 17, and 19 represents a parting edge of the attic provided at the outer end of the eave board and the lower end of the fascia board 13.

20, 20... are purlins installed at appropriate intervals on the upper chord members 8b of the isosceles triangular truss 7, and on these purlins 20, 20..., shedding boards 21 are stretched along the upper chord members 8b. It is being

Reference numerals 22, 22, . 23 is an attic splint interposed between the outermost main building 20 and the upper end of the fascia base plate 13, and 24 is an attic splint between the outer end of the roof board 22 and the upper end of the fascia base plate 13. This is an attic ridge drain provided in the parting part, and 25 is an attic ridge installed inside this attic attic ridge drain 24. On the other hand, reference numeral 26 designates the other roof board that is provided in an inclined manner from the lower end of the belly member 9 along the upper chord member 6a of the right triangular truss 3a.

The numeral 27 designates a lighting window that is provided inwardly below the eaves 29, which is thus formed to protrude above the roof. This lighting window 27 has the following structure. That is, 30 is a horizontal bar with a lintel extending laterally at the upper end of the belly member 9, and 31 is a horizontal bar with a window sill extending laterally at the lower end of the belly member 9. 32 is lintel 3
3 and a window sill 34.
35 is a translucent window member attached to this sash 32. In this way, the skylight is brought into the attic 33 through the daylight window 27 provided horizontally on the roof 28.

Effects As described above, the present invention provides lighting windows in the upper and lower sides of the outer end of the triangular truss that is fixed to the roof roof frame, making it sufficiently resistant to cross winds. It is. Moreover, by making the top chord of the triangular truss protrude outward from the top chord of the triangular truss to form the eaves, it is possible to not only prevent rainwater from entering, but also block strong direct light and allow only skylights to be introduced. It was made.
