Description

  The present invention relates to a ventilation building, and more particularly, to a ventilation building attached to a single-flow roof for natural ventilation of a hut space in a house.

  FIG. 9 is a plan view showing the external shape of the ventilation building disclosed in Patent Document 1, and FIG. 10 is a cross-sectional view taken along line XX shown in FIG. It shows the state.

  With reference to these drawings, the ventilation building 60 is mainly configured by a building plate member 61 and a pair of ventilation members 62 a and 62 b attached to the lower surface of the building plate member 61. The ridge board member 61 includes inclined portions 64a and 64b extending obliquely downward from the apex in the width direction (vertical direction in FIG. 9), and each of the inclined portions 64a and 64b has a longitudinal direction (in FIG. 9). A plurality of ventilation openings 65 extending in parallel to the left and right direction are formed. And ventilation member 62a, 62b is attached to the lower surface of each of inclination part 64a, 64b, Comprising: The space between the vertex and each of the ventilation port 65 is attached.

  Each of the ventilation members 62a and 62b has a trapezoidal cross section in the width direction, and a plurality of air holes (not shown) penetrating from one side surface to the other side surface in the width direction. Each of the ventilation members 62a and 62b is attached so that the surface corresponding to the lower bottom longer than the upper bottom is located on the lower surface side of each of the inclined portions 64a and 64b of the ridge plate member 61. Note that each of the ventilation members 62a and 62b has basically the same structure as the ridge cover material disclosed in Patent Document 2, and therefore under a certain condition, ventilation performance and waterproofing through a ventilation hole (not shown). Performance can be demonstrated.

  The ventilation building 60 configured as described above is installed on the roof material 67 having a substantially mountain shape and an opening at the center thereof, and then fixed to the roof material 67 by the fixing nails 69. At this time, since the surface corresponding to the lower bottom of the trapezoidal cross-sectional shape of the ventilation members 62a and 62b is attached to the lower surface side of each of the inclined portions 64a and 64b, the space below the center side is expanded. Therefore, since the possibility of buffering with the drain 68 of the roofing material 67 during installation is reduced, the installation of the ventilation building 60 is facilitated.

  When the ventilation building 60 is in a ventilated state, as shown by the arrows in FIG. 10, the air rising from between the drains 68 at the center of the roofing material 67 passes through each of the ventilation members 62 a and 62 b. It passes from the inner side to the outer side through the pores. And the passed air is discharged | emitted outside through each of the ventilation openings 65 currently formed in each of the inclination parts 64a and 64b.

  Further, rainwater enters mainly below the inclined portions 64a and 64b through the ventilation ports 65, respectively. And as above-mentioned, the ventilation members 62a and 62b are comprised so that the rainwater which entered may not move to the inward side through each ventilation hole of the ventilation members 62a and 62b. Accordingly, the ventilation building 60 has a ventilation function and a waterproof function.

FIG. 11 is a view showing an attachment state of another ventilation building disclosed in Patent Document 1 to the roof material, and corresponds to FIG.
With reference to the drawings, the basic structure of the ventilation building 70 is the same as that of the ventilation building 60 shown in FIG. In the ventilation building 70, the attachment states of the ventilation members 62a and 62b are different. That is, the ventilation members 62a and 62b are attached so that the surfaces corresponding to the upper bases of the ventilation members 62a and 62b are positioned on the lower surfaces of the inclined portions 64a and 64b of the ridge plate member 61, respectively. Therefore, the length of the vent hole formed in each of the ventilation members 62a and 62b becomes longer as going downward. And since the rain water which infiltrated from the outside mentioned above exists in the downward side (the roof material 67 side) inside the ventilation building 70, the waterproof function of the ventilation members 62a and 62b is more efficiently exhibited. I can do it.

  Next, the detailed structure of the ventilation member 20 will be described.

  FIG. 4 is a schematic perspective view showing the external shape of the ventilation member shown in FIG.

  Referring to the drawings, as described above, the ventilation member 20 has a trapezoidal shape in the cross section in the width direction, and has a length substantially the same as the length in the longitudinal direction of the inclined portion of the ridge plate member with respect to the longitudinal direction. It has a shape. Specifically, the ventilation member 20 is integrally connected to each other by heat fusion in a state where a plurality of synthetic resin sheets each having an uneven cross-sectional shape are stacked. And many ventilation holes 21 which penetrate from one side wall to the other side wall are formed.

The length C corresponding to the height of the shape is 18 mm. The vent hole 21 is set to a rectangular opening size of approximately 1 mm × 4 mm. Such a ventilation member 20 basically has the same structure as the ridge cover material disclosed in Patent Document 2 as in the conventional example. As a result, under certain conditions, the ventilation member 20 can ventilate through the vent hole 21, and also exhibits ventilation performance and waterproof performance that prevents rainwater from entering through the vent hole 21. It becomes. And by using such a ventilation member 20, it contributes to the weight reduction and cost reduction of a ventilation building.

  As described above, the ventilation wing 1 shown in FIG. 1 is obtained by integrating the ridge board member 10 and the ventilation member 20 that exerts ventilation performance and waterproof performance.

  Next, attachment of the ventilation building 1 shown in FIG. 1 to the roof material will be described.

  FIG. 5 is a schematic exploded end view showing a state before the ventilation building shown in FIG. 1 is attached to the single-flow roof.

  Referring to the drawing, the single-flow roof 7 has an outer wall 71 extending vertically downward, and a roof material 72 extending obliquely downward in which a rectangular opening 73 extending in the longitudinal direction is formed at the apex side portion thereof. . Specifically, the roofing material 72 includes a field board 85 installed on a rafter (not shown), a waterproof paper 86 laid on the upper surface of the field board 85, and an underlaying material 87 installed on the waterproof paper 86. And a flat roof tile 88 installed on the lower roof material 87. Further, a drainage drain 75 provided at the lower edge of the opening 73 and an inverted C-shaped closing member 76 provided at the upper edge of the opening 73 are mounted on the waterproof paper 86. In this state, the lower brazing material 87 is installed.

  The ventilation building 1 is lowered from above so as to cover the single-flow roof 7 on the single-flow roof 7 thus configured. Then, the plate member 31 and the seal member 35 are installed on the roof material 72 below the opening 73, and the first flange portion 13 is installed on the roof material 72. That is, the plate member 31 and the seal member 35 shield water between the ventilation member 20 and the roof material 72. Further, the lower surface of the inclined portion 11 of the building board member 10 is installed on the upper surface of the closing member 76. Further, the hanging portion 15, the horizontal portion 16, and the second flange portion 17 are located on the outer side of the outer wall 71, and the crosspiece 51 and the seal member 53 are in contact with the outer wall 71.

  Thus, when the ventilation building 1 is installed on the single-flow roof 7, it will be in the state shown in FIG.

  FIG. 6 is a schematic end view showing a state where the ventilation building shown in FIG. 1 is attached to the single-flow roof.

  Referring to the figure, when the ventilation building 1 is attached to the single-flow roof 7, the fixing nail 45 is inserted with the waterproof packing 44 attached to the lower side of each of the attachment holes 43 of the inclined portion 11 shown in FIG. And type. Further, in the second flange portion 17, the fixing nail 46 is driven from the outer side toward the outer wall 71 so as to penetrate the seal member 53. In this way, the ventilation building 1 is fixed to the outer wall 71 and the roof material 72. Then, the attachment to the single-flow roof 7 of the ventilation building 1 is completed.

  As described above, the ventilation member 20 having ventilation performance and waterproof performance is integrated with the ridge board member 10 corresponding to the shape of the single-flow roof 7. Therefore, the ventilation tower 1 can be easily attached to the single-flow roof 7 and the reliability of the ventilation function and the waterproof function is improved.

  In addition, the ventilation member 20 is protected by the plate member 31 and the sealing member 35 which are sealing means, and the sealing performance between the ventilation member 20 and the roof material 72 is stabilized. Therefore, the durability of the ventilation member 20 is improved and the reliability of the installed state of the ventilation building 1 is improved.

  Furthermore, since the inclined portion 11 of the ridge board member 10 is installed on the upper surface of the closing member 76, the strength of the inclined portion 11 of the portion supported by the closing member 76 is improved. Therefore, the attachment state to the single-flow roof 7 of the ventilation building 1 is stabilized.

  Furthermore, the heat insulating material 19 attached to the lower surface of the inclined portion 11 of the ridge board member 10 is attached so as to be positioned between the closing member 76 and the ventilation member 20 as described above. Therefore, dew condensation from the ridge board member 10 due to the airflow is prevented. Therefore, the drop of water droplets into the cabin space through the opening 73 of the roof material 72 is prevented, so that the reliability of the ventilation building 1 is improved.

  In the ventilation state, as shown by the arrows, the air rising from the opening 73 of the roof material 72 moves only to the ventilation member 20 side due to the effect of the closing member 76. Then, it passes outward through the ventilation hole of the ventilation member 20. And the air which passed the ventilation member 20 is discharged | emitted outside through each of the ventilation port 42 of the inclination part 11. FIG.

  On the other hand, rainwater enters mainly below the inclined portion 11 through each of the ventilation ports 42. As described above, the infiltrated rainwater cannot be moved inward through the ventilation hole of the ventilation member 20. Accordingly, the rainwater that has entered enters the outside through the gap between the lower surface of the first flange portion 13 and the upper surface of the roof material 72 via the upper surface of the plate member 31.

  Here, the further waterproof effect by the shape of the ventilation member 20 is demonstrated.

  FIG. 7 is a schematic end view showing the state of airflow in the ventilation building shown in FIG.

  Referring to the drawing, as indicated by arrows, the air that has entered from the outside through the ventilation port 42 moves inward through the ventilation hole of the ventilation member 20. And the air which moved to the inward side will move to the attic space through the opening 73 of the roofing material 72. At this time, the air that has moved inward cannot move upward from the closing member 76, so that almost all of the air moves into the opening 73. That is, the air flow from the ventilation member 20 toward the opening 73 is caused to pass through the right-angle duct by the closing member 76.

Therefore, each of the air flowing through the upper and lower sides in the ventilation building 1 has different moving distances until reaching the shed space through the opening 73. That is, the air flowing upward travels a longer distance to the cabin space than the air flowing downward. Accordingly, the velocity V ₁ of the upper air stream is higher than the velocity V ₂ of the lower air stream. That is, the velocity V ₁ of the airflow passing through the lower bottom side (upper surface side) of the ventilation member 20 is larger than the velocity V _{2 of} the airflow passing through the upper bottom side (lower surface side). Therefore, when rainwater has penetrated through the ventilation opening 42 is about to pass through the vents of the ventilation member 20, rainwater moved by the upper surface side of the air flow with a velocity V ₁ was, the lower surface having a velocity V ₂ stream Will move faster than moving rainwater.

  And as above-mentioned, the ventilation member 20 is attached so that the surface (upper surface) corresponding to the lower base longer than the upper base may be located in the lower surface side of the inclination part 11 of the ridge board member 10. As shown in FIG. Therefore, the length of the vent hole formed in each of the ventilation members 20 becomes longer as it goes upward. That is, since the waterproof function increases as it goes upward, the water shielding performance of the ventilation member 20 is efficiently exhibited corresponding to the velocity distribution of the airflow.

  FIG. 8 is a schematic end view showing a ventilation building according to the second embodiment of the present invention, which corresponds to FIG. 6 of the first embodiment.
