Description

  The present invention relates to a ventilation building structure in a building such as a large building of a house, and particularly relates to a device capable of improving ventilation efficiency.

  In order to prevent rainwater from entering the house in the ridge of the house, a wet construction method in which the gap between the corner tile and the rafter is solidified using soil, namba, plaster or the like has been conventionally used. However, since it is difficult to perform indoor ventilation with the wet method, a ridge structure having a ventilation function is being adopted in recent years (see, for example, Patent Documents 1 and 2).

FIG. 34 is a diagram showing an example of a ridge structure having such a ventilation function. A ventilation slit 202 is formed in the ridge 201 of the base plate 200 which is the basic configuration of the roof. A ridge fitting 203 is provided so as to straddle the ventilation slit 202, and a rafter 204 arranged in the horizontal direction is supported by the ridge fitting 203. It is covered with a crown tile 203 from above the rafter 204. Further, on the base plate 200, a crosspiece 210 is attached, and a crosspiece 211 is attached to the crosspiece 210.

  FIG. 1 is a sectional view showing a large building 10 to which a ventilation building structure according to the first embodiment of the present invention is applied, and FIG. 2 is a sectional view showing an enlarged main part. In the following description, the same reference numerals are given to the same functional parts.

  As shown in FIG. 1, a large building 10 having a ventilation building structure is formed by a pair of field boards 11 and 11 that partition indoors and outdoors. The pair of field boards 11 and 11 are disposed to face each other with a ventilation slit 12 therebetween. A plurality of pedestals 13 arranged in the horizontal direction are provided on the top of the field boards 11, 11, and the ledges 14 are supported by these pedestals 13. The pier 13 is provided with a ventilation hole 13a.

  A plurality of rafter support fittings 20 are arranged at predetermined intervals across the ventilation slit 12, and a rafter 30 is attached across the plurality of rafter support fittings 20. Further, a draining plate 40 is disposed across the ventilation slit 12. A waterproof plate 50 is disposed at an upper portion of the rafter 30 at an appropriate interval. Further, a waterproof face door 60 is attached from the side surface of the rafter 30 to the top of the roof tile 14. A crown tile 70 is placed on the waterproof plate 50.

  The rafter 30 includes, for example, a rafter body 31 formed in a rectangular cross section, upper and lower flow holes 32 formed on both side surfaces of the rafter body 31, and a rafter body 31 as shown in FIGS. And horizontal flow holes 33 formed on the upper surface. The upper and lower flow holes 32 have a function of flowing the air below the rafter 30 upward, and the horizontal flow holes 33 have a function of flowing the air on the side of the rafter 30 to the opposite side.

  As shown in FIGS. 5 and 6, the same effect can be obtained by forming the upper and lower flow grooves 34 instead of the upper and lower flow holes 32. Further, as shown in FIGS. 7 and 8, the same effect can be obtained even if the rafter main body 31 is directly provided with the upper and lower flow holes 35 and the horizontal flow holes 36.

  For example, as shown in FIG. 9, the draining plate 40 is provided on the side of the plate 41 and a roof-type plate 41 having a shape for draining water dripped from above to the side, that is, the top surfaces of the field plates 11 and 11. And a ventilation portion 42 that communicates the ventilation slit 12 and the rafter 30 side.

  In addition, as shown in FIG. 10, the same effect is acquired even if it is the draining board 40A which provided the ventilation hole 43 instead of the ventilation part 42. FIG. Furthermore, as shown in FIG. 11, the same effect can be obtained even with a draining plate 40B provided with a ventilation unit 44 that ventilates in the vertical direction instead of the ventilation unit 42 that ventilates in the horizontal direction.

  Further, like a draining plate 40C shown in FIG. 12, a roof-type plate member 45 and a pair of ventilation portions 46 provided on the front end side of the plate member 45 and configured by a partition plate in the vertical direction are provided. May be. At this time, when the vertical dimension of the ventilation part 46 is h, and the horizontal dimension of the ventilation slit 12 (see FIG. 1) is 2d, h is preferably d or more. That is, by setting it as such a dimension, while being able to perform sufficient ventilation, it can prevent that rainwater dripping from the ventilation slit 12. FIG.

  Further, as in the draining plate 40D shown in FIG. 13, a roof-type plate material 41 having a shape for draining water dripped from above to the side, that is, the top surfaces of the field plates 11 and 11, and a side surface of the plate material 41 is provided. The ventilation slit 47 communicates with the rafter 30 side. At this time, when the vertical dimension of the ventilation part 47 is h and the horizontal dimension of the ventilation slit 12 is 2d, it is preferable that h is d or more. That is, by setting it as such a dimension, while being able to perform sufficient ventilation, it can prevent that rainwater dripping from the ventilation slit 12. FIG.

  For example, as shown in FIG. 12, the waterproof plate 50 has a function of draining water dripped from above onto the top of the roof tile 14 so as not to flow into the rafter 30. The same effect can be obtained even with the waterproof plate 50A having the shape as shown in FIG.

  For example, as shown in FIG. 14, the waterproof surface door 60 includes a first portion 61 disposed along the side surface of the rafter 30 and a second portion 62 disposed along the upper surface of the roof tile 14. It has a function to prevent rainwater blown from the side from entering the room. In addition, as shown in FIG. 15, even if it is the waterproof surface door 60A which has the 2nd site | part 63 which consists of a flexible member, the same effect can be acquired.

  In the large wing 10 configured as described above, indoor air reaches the lower part of the rafter 30 through the ventilation slit 42 of the draining board 40 from the ventilation slit 12. Then, it passes above the rafter 30 through the upper and lower flow holes 32. And it will come out from the lower surface side of the waterproof board 50 to the outdoors. In addition, rainwater does not flow indoors by the draining board 40 or the waterproof face door 60. Therefore, it is possible to simplify the ventilation path Q through which indoor air passes to the outside while maintaining basic functions such as a water stop effect, and improve ventilation efficiency.

  In addition, since the water stop effect is not impaired even if it is applied to the corner building and the descending building in addition to the large building, the ventilation efficiency can be further improved. In addition, since the rafter 30 itself has an air flow function, there is an advantage that the cost is lower than that of a complicated structure using many metal fittings.

  On the other hand, since the rafter 30 has a function of allowing air to flow in the horizontal direction as well, as shown in FIG. As a result, the exhaust capacity can be improved, and the air staying on the rafter 30 can be efficiently flowed to the outside.

  Moreover, since the crosspiece 13 is provided with the ventilation hole 13a, the air between the crosspiece 14 and the field board 11 can be discharged outdoors as indicated by the ventilation path R.

  As described above, in the large building 10 to which the ventilation building structure according to the embodiment of the present invention is applied, it is possible to perform sufficient ventilation of the house with a simple structure, and the cost associated with the construction is also reduced. be able to.
