Description

  The present invention relates to a ventilation structure in a shed space of a house.

  Conventionally, a ridge ventilation structure is known as a ventilation structure of a house shed. In this building ventilation structure, outside air that has flowed in through an intake port such as an outer wall is exhausted from an exhaust port in the building part via a cabin space, and utilizes natural convection generated by a temperature difference of air.

On the other hand, when the roof is horizontal or the roof slope is small, such as a flat roof, natural convection hardly occurs in the back of the hut. Therefore, the ridge ventilation structure cannot sufficiently ventilate the back of the hut. Therefore, a technique has been proposed in which an exhaust port is formed in the upper part of the parapet, and exhaust is performed from the exhaust port in the upper part of the parapet through the hollow part inside the outer wall from the back of the hut (see Patent Document 1).

This gypsum board 2g forms a rectangular cylindrical body upward from the opening on the ceiling C surface.

  The top light 3 protrudes from the upper end surface of the rising part 2 and is inclined from the horizontal plane at the upper part of the rising part 2. Further, the top light 3 has a structure that can be opened and closed by electric drive, and the indoor ventilation can be performed by opening the top light 3.

  As shown in FIG. 2, the four ventilation panels 4 to 7 are installed on the flat roof R in contact with the outer peripheral surface of the rising portion 2. Between these adjacent ventilation panels 4 to 7, four guide members 8 that are also installed on the land roof R are provided, and the ventilation panels 4 to 7 are attached to these guide members 8 by fastening materials. It is fixed. The fastening material means nails, screws, adhesives, and the like.

  The ventilation panels 4 to 7 have lower end openings 4a and 5a (see FIG. 1) on the lower end surface and upper end openings 4b to 7b on the upper end surface, respectively, and these lower end openings 4a and 5a (see FIG. 1). ) And the upper end openings 4b to 7b. Further, the upper end surfaces of the two ventilation panels 6, 7 provided along the inclination direction of the top light 3 are flush with the upper end surfaces of the adjacent rising portions 2. On the other hand, the upper end surfaces of the two ventilation panels 4, 5 provided orthogonal to the inclination direction of the top light 3 are lower than the upper end surfaces of the adjacent rising portions 2. Further, an insect screen 9 for preventing insects from entering and dropping is attached to the upper end openings 4b to 7b of the ventilation panels 4 to 7, and the ventilation panels 4 to 7 and the guide member 8 are provided on the outer peripheral surfaces thereof. A vinyl chloride sheet 11 (see FIG. 1) is attached.

  As shown in FIG. 1, roof openings R1 and R2 are formed on the land roof R at positions corresponding to the lower end openings 4a and 5a of the ventilation panels 4 and 5, and the ventilation panels 4 and 5 The lower end openings 4a and 5a are aligned with the roof openings R1 and R2. Similarly, the ventilation panels 6 and 7 have a lower end opening (not shown) aligned with a roof opening (not shown).

  As shown in FIG. 1, the draining member 10 extends from the side surface of the toplight 3 so as to cover the upper side of the ventilation panels 4 and 5, and connects the upper end openings 4 b and 5 b of the ventilation panel and the outdoors. Is secured to the side surface side of the ventilation panels 4 and 5 while being separated from the ventilation panels 4 and 5. Similarly, the draining member 10 also extends above the upper end openings 6b and 7b (see FIG. 2) of the ventilation panels 6 and 7 (see FIG. 2), and the upper end openings 6b and 7b of the ventilation panel and In order to secure a passage that communicates with the outside, it is bent toward the side surfaces of the ventilation panels 6 and 7 while being separated from the ventilation panels 6 and 7.

  Next, the flow of air in the ventilation structure 1 in the back of the hut configured as described above will be described.

  First, air that has been warmed and lightened in the shed G rises and enters the ventilation panels 4 to 7 through the roof openings R1 and R2 and the lower end openings 4a and 5a provided on the land roof R. Moving.

  The air that has moved into the ventilation panels 4 to 7 continues to rise, and is discharged out of the ventilation panels 4 to 7 through the upper end openings 4b to 7b. Although the air discharged from the upper end openings 4b to 7b is prevented from rising by the draining member 10, the air newly discharged from the upper end openings 4b to 7b enters the gap between the draining member 10 and the ventilation panels 4 to 7. It is pushed out and exhausted to the outdoors.

  In this way, convection of air exhausted from the cabin back G to the outside occurs, and ventilation of the cabin back G is performed.

According to the above embodiment, the air heated in the attic G is the roof openings R1 and R2 formed in the land roof R and the lower end openings 4a and 5a corresponding to these roof openings R1 and R2. Through the ventilation panels 4 to 7 through the upper end openings 4b to 7b to the outside of the ventilation panels 4 to 7 and exhausted to the outside. Therefore, the inside of the hut G can be ventilated. Moreover, since this ventilation structure 1 of a shed can be formed in the desired location of the flat roof R, the flow path through which the air in the shed G moves to the ventilation panels 4-7 can be shortened. . Therefore, the ventilation of the cabin G can be performed quickly. Furthermore, since the air in the attic G moves inside the ventilation panels 4 to 7, the air can move without stagnation, and the attic G can be efficiently ventilated.
Moreover, since the top light 3 is provided in the rising part 2, favorable indoor lighting can be ensured.

  Further, since the draining member 10 extends from the top light 3 to above the upper end openings 4b to 7b of the ventilation panels 4 to 7, the boundary between the top light 3 and the rising part 2, the rising part 2 and the ventilation part It is possible to prevent rainwater from penetrating into the boundary with the panels 4 to 7 and the ventilation panels 4 to 7.

  The upper end surfaces of the ventilation panels 4 and 5 are provided lower than the upper end surface of the rising portion 2, and the upper end surfaces of the ventilation panels 6 and 7 are flush with the upper end surface of the rising portion 2. It is possible to prevent the ventilation panels 4 to 7 from blocking the light inserted into the top light 3. Therefore, indoor daylighting is improved.

  Furthermore, since the heat insulating material 2e is provided in the rising part 2, ie, heat insulation panel 2a, 2b, it can prevent that the heat | fever of the air which moves the inside of the panels 4-7 for ventilation is transmitted to a room | chamber interior.

  Further, four ventilation panels 4 to 7 are provided on the peripheral surface of the rising portion 2, and a guide member 8 is provided between the adjacent ventilation panels 4 to 7. Therefore, the ventilation panels 4 to 7 can be easily positioned, and the ventilation panels 4 to 7 can be securely fixed.

  In the above embodiment, the ventilation structure 1 in the attic is formed on the flat roof R. However, the present invention is not limited to this, and the roof structure is formed on a roof with a large roof slope, a horizontal flat roof, or the like. Also good. Moreover, the ventilation structure 1 of a hut back may be formed in the edge part etc. of a roof, and may be provided with two or more with respect to one roof. Furthermore, the heat insulating material 2e provided in the rising part 2 should just have heat insulation, such as glass wool and rock wool.

It is sectional drawing which shows the structure of one Embodiment of the ventilation structure of the hut back which concerns on this invention. It is a schematic perspective view of the state which removed the draining member of the ventilation structure of the hut back which concerns on this invention.
