Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a condensation water draining device for assembly buildings such as sunrooms, for example.

Conventional technology As this type of device, for example,
As disclosed in Japanese Patent No. 98005, it is known that a gap for draining condensed water is provided between the outer surface of the eave girder and the inner surface of the lower edge of the roof plate having a substantially L-shaped cross section.

Problems to be Solved by the Invention In the above device, the condensed water flowing along the inner surface of the roof shingles from the horizontal to the vertical parts is discharged outside the building through the condensation water discharge gap. However, condensed water that falls directly from the horizontal parts of the roof without flowing up to the vertical parts of the roof shingles can scatter inside the building, causing discomfort to residents. .

The purpose of this invention is to provide a condensation water draining device for a building that solves the above problems.

Means for Solving the Problems The dew condensation water discharge device according to this invention is based on the above-mentioned conventional building condensation water discharge device, and a heat insulating panel with an approximately L-shaped cross section is placed inside the roof board, and the edge of the heat insulating panel is A rail that receives the section is installed on the eave girder,
The rail is characterized in that it is formed in the shape of a gutter without an outer wall, and has a bottom surface that extends to and is flush with the inner edge of the top surface of the eave girder.

Function: In the condensation water draining device for a building according to this invention, a heat insulating panel having a substantially L-shaped cross section is arranged inside the roof board, so that the condensation water falling from the horizontal part of the roof board can be caught by the heat insulating panel.

Furthermore, since the eaves sill is provided with a rail that receives the lower edge of the insulation panel, the rail catches the condensed water that flows along the outer surface of the insulation panel from the horizontal part to the vertical part of the insulation panel.

Furthermore, since the rail is formed in the shape of a gutter without an outer wall and has a bottom surface that extends to and is flush with the inner edge of the top surface of the eave girder, the condensed water received by the rail is absorbed by the eave girder. The dew condensation water is sent to the top surface of the building and is finally discharged outside the building through the condensation water drainage gap.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings.

The drawing shows the eaves of the sunroom.

The sunroom has 11 eave girders and the lower edge is 11 eave girders.
A roof plate 12 having a substantially L-shaped cross section covering the front surface of
and inner and outer heat insulating panels 13, 14, which are arranged inside the roof board 12 and whose lower edges are supported by the eave beams 11 and have a generally L-shaped cross section.

The eave girder 11 is made of an aluminum extruded material with a substantially square cross section, and has inner and outer side walls 17,1.
8, consisting of a top wall 19 and a bottom wall 20. outer wall 1
In the part near the lower edge of 8, there is a gutter 2 with a roughly L-shaped cross section.
1 is provided integrally. An outward internally expanding groove 22 is provided at the upper end of the outer wall 18.
A heat insulating packing 23 is fitted into this so that a portion thereof protrudes. Insulation packing 23
As shown in FIG. 2, the groove 22 is fitted over almost the entire length of the internal enlarged groove 22, and a notch 31 is provided at the end thereof. Top wall 1 of eave girder 11
A rail 15 that guides the lower edges of the inner and outer heat insulation panels 13 and 14 is provided at the inner edge of the panel 9 . The rail 15 is gutter-like without an outer wall, and
It has vertical side walls 35 and a bottom wall 37. A vertical partition wall 36 is formed in a rising shape in the widthwise central portion of the bottom wall 37, and inner and outer roller running portions 39 and 40 are formed on both sides of this wall, respectively.
The outer edge of the bottom wall 37 of the rail 15 is the top wall 19 of the eave gutter 11
It is connected to the inner edge. Further, although it may not be clearly visible to the naked eye, the upper surfaces of the top wall 19 and the bottom wall 37 are slightly inclined forward and downward from the inner edge of the bottom wall 39 of the rail 15 to the outer edge of the top wall 19. At the end of the partition wall 36 of the rail 15,
As shown in FIG. 2, a notch 41 is provided, and similarly notches 42 and 43 are provided at the ends of both roller running sections 39 and 40, respectively.

The roof plate 12 is made of a transparent material made of acrylic resin or glass, and has a vertical front wall 24 and a top wall 25 that extends rearward from the upper end of the vertical front wall 24 and slopes forward and downward. Although not shown in detail, both side edges of the roof plate 12 are supported by being sandwiched between rafters 44 and a retaining cover 45. The lower edge of the front wall 24 covers the upper part of the outer surface of the outer wall 18 of the eaves beam 11, and its inner surface is placed against the heat insulating packing 23. Outer wall 18 of eave girder 11 and roof board 1
A gap 26 corresponding to the thickness of the protrusion of the heat insulating packing 23 is formed between the lower edges of the heat insulating packing 23.

The inner and outer heat insulating panels 13, 14 have similar cross-sectional shapes, and although not shown in detail as a whole, both have a frame structure. The inner heat insulation panel 13 consists of a light shielding plate 27 such as an aluminum plate and a frame 28 surrounding it. The external heat insulation panel 14 is a light transmitting plate 2 made of the same material as the roof panel 12.
9 and a frame 30 surrounding it. Vertical and horizontal rollers 33, 34 are attached to the lower ends of the frames 28, 30 of the inner and outer heat insulating panels 13, 14, respectively. The vertical rollers 33 of both heat insulation panels 13 and 14 are connected to both roller running portions 39 and 4 of the rail 15.
Each rolls on 0. On the other hand, inner insulation panel 1
The horizontal rollers 34 of No. 3 roll along the side wall 35 of the rail 15, and the horizontal rollers 34 of the external heat insulation panel 13 roll along the partition wall 36 of the rail 15. Although not shown, rollers are also attached to the rear edges of both the heat insulation panels 13, 14, and the rollers are supported by rails.

A part of the condensed water that has formed on the inner surface of the roof shingle 12 flows down the roof shingle 12 to its lower edge, and the rest tries to fall into the room, but the inner and outer insulation panels 13 and 14 catch it. . The condensed water caught by the insulation panels 13 and 14 flows down through the insulation panels 13 and 14, and the rail 1
You can take it in 5. The condensed water received by the rail 15 is sent onto the top wall 20 of the eaves beam 11 through the notches 41 to 43, merges with the condensed water received on the top wall 20, and is discharged outdoors through the gap 26. It is received by gutter 21.

Effects of the invention According to this invention, condensed water that falls from the horizontal part of the roof shingle is caught by the insulating panel, and condensed water that flows along the outer surface of the insulated panel from the horizontal part to the vertical part of the insulated panel is caught by the rail. , the condensed water received by the rail is sent to the top of the eave girder, and finally,
Since the condensed water is discharged to the outside of the building through the drainage gap, it is possible to reliably prevent the condensed water from scattering inside the fabric.
