Description

[Detailed description of the invention] Industrial field of application The invention relates to auxiliary assembly buildings such as sunrooms.

Prior Art and its Problems In the above-mentioned auxiliary assembly building, hot air and humid air are trapped inside the building, so it is necessary to exhaust the air.

Therefore, the present applicant first provided the ridge with an exhaust port that communicates the indoors with the outdoors, provided the exhaust port with a damper, and provided with a blower that sends indoor air from the exhaust port to the outdoors. proposed an auxiliary assembly building (see Utility Model Application Publication No. 60-2741). This auxiliary assembly building attempts to efficiently exhaust the above-mentioned air and prevent water from entering through the exhaust port by opening and closing the damper, but this has the following problems. That is, although the assembly building requires means for opening and closing the damper, the cost of the parts for constructing the means is quite high, and the assembly of the parts is troublesome. Furthermore, if the assembly precision of each part is poor,
The damper could no longer open and close smoothly, allowing rainwater to enter through the exhaust port.

The purpose of this invention is to provide an auxiliary assembly building that solves the above-mentioned problems.

Means for Solving the Problems The auxiliary assembly building according to this invention is provided with a rain cover member whose cross section is approximately inverted L-shaped from the top of the roof to the front thereof, and an exhaust port is provided in the front wall of the rain cover member. The duct is connected to the exhaust port so that at least the entire front part of the duct protrudes forward and downward from the front wall, and the rain cover member has a downwardly inclined wall protruding from the front so as to cover the upper part of the duct to the front. It is provided in

Embodiment As shown in FIG. 1, the vertical section of the ridge of the auxiliary assembly building has a substantially S-shaped rear frame member 3 that is horizontally fixed to the roof wall 1 with bolts 2 and has a vertically long cross section. and a roof shingle receiving member 4 having a substantially horizontally H-shaped cross section and arranged at a predetermined interval in front of the lower part of the rear frame member 3, and between the top surface of the roof shingle receiving member 4 and the front upper part of the rear frame member 3. and a crossflow fan 6 housed in a space surrounded by the rear frame member 3 and the rain cover member 5 with an open bottom. There is.
The rear frame member 3, the roof plate receiving member 4, and the rain cover member 5 are all made of extruded aluminum. The roof plate receiving member 4 has a pair of upper and lower opposing walls 9 that are sandwiched between the rear edges of the roof plate 8 via a heat insulating material 7, etc., and a frame member 10 such as a roof beam at both left and right ends. is supported by Rain cover member 5
consists of a combination of two members, one of which is a front wall 11 that extends almost vertically upward from the roof plate receiving member 4, and the other is a top that extends almost horizontally backward from the upper end of the front wall 11. This is wall 12. A flat fan mounting member 13 extending almost horizontally rearward from the lower end of the front wall 11
is integrally provided, and a fan 6 is attached to this. Both left and right ends of the fan mounting member 13 are supported by the frame member 10 via mounting fittings 14 . The front wall 11 includes an upper front wall 16 and a lower front wall 17 that are vertically connected via a horizontal step 15 at the center of the height, and an engaging ridge that extends forward from the upper edge of the upper front wall 16. 18, and a water-repelling flange 19 that is continuous with the horizontal step portion 15 and extends forward in parallel with the engaging flange 18. Horizontal step 1
5 is formed with an upwardly opened groove 20 on the rear side of the upper front wall 16, which functions as a rainwater exhaust port as will be described later. And the upper front wall 1
6 has a rectangular exhaust port 21 that is long in the left-right direction, and a duct 22 is connected to the exhaust port 21 in a manner that projects forward. The duct 22 includes a circumferential wall 23 having a substantially rectangular cross section at the peripheral edge of the exhaust port 21, a partition wall 24 parallel to the upper and lower walls of the circumferential wall 23 that partitions the inside of the circumferential wall 23 into upper and lower parts, and a partition wall 24 at the rear end of the circumferential wall 23. It consists of a flange 25 provided. A twist bolt 26 passes through the flange 25 and is screwed into the upper front wall 16 at the front face of the flange 25, thereby attaching the duct 22 to the front face of the upper front wall 16. In this state, the upper and lower walls of the peripheral wall 23 and the partition wall 2
4 is tilted forward and downward. At the front edge of the top wall 12, a downwardly protruding portion having an L-shaped cross section is formed on the lower surface of the top wall 12, so that an engagement groove 27 that opens rearward is formed.
is provided, into which the engaging protrusion 18 of the front wall 11 is fitted. Further, a lower front inclined wall 28 is integrally provided at the front edge of the top wall 12. The inclined wall 28 covers a portion of the duct 22 from the top to the front, and has a draining function and a rectifying function for the exhausted air. Further, the inclined wall 28 is bent downward near its front edge, and the portion in front of the bent portion has a larger inclination angle than the portion behind the bent portion. A rising portion 29 is provided at the rear edge of the top wall 12, through which a tapping screw 30 is inserted.
is screwed into the rear frame member 3.

When the cross-flow fan 6 is operated, indoor hot air and humid air passes through the duct 22 from the exhaust port 21, is guided by the sloped wall 28, and flows downward, colliding with the front edge of the sloped wall 28 and the roof board. It is discharged outdoors from between 8 and 8.

When it rains, the rain will not enter the duct 22 because the duct 22 is covered by the sloped wall 28 from above to the front. Further, even if a phenomenon occurs in which rainwater rises up on the roof surface due to wind pressure caused by strong winds, the rainwater (L) due to this phenomenon intrudes below the duct 22, but does not intrude into the interior thereof. Even if rainwater enters the duct 22 and passes through the exhaust port 21, the concave groove 20 of the horizontal step 15 drains the rainwater.

Effects of the invention In the auxiliary assembly building according to this invention, a rain cover member 5 having a substantially inverted L-shaped cross section is provided from the top of the roof to the front thereof, and an exhaust port 21 is opened in the front wall 11 of the rain cover member 5 to exhaust air. A duct 22 is connected to the opening 21 so that at least the front part of the entire duct 22 protrudes obliquely forward and downward from the front wall 11, and the rain cover member 5 is provided with a downward slope in the front so as to cover the upper to front part of the duct 22. Since the wall 25 is provided in a protruding shape, it is possible to reliably prevent rainwater from entering through the exhaust port, and as a means for this purpose, no movable parts such as the damper mentioned at the beginning are used. Therefore, there are no problems associated with the damper mentioned at the beginning.
