  However, no consideration is given to “ventilation” for this house. That is, in the conventional case, the air behind the shed of the lower house cannot be released outdoors. This is apparent from the description of Patent Document 2, but it is ideal if the air behind the shed of the lower house can be released outdoors.

  If hot air or moisture accumulates in the back of the hut, not only will air conditioning become inefficient, but it will also become a hotbed for mold and mites that also cause asthma. Also, if the lower house is also hermetically sealed, moisture contained in the air condenses and forms dew at the low temperature part, causing aging of the heat insulating material and corrosion of the housing. Under the influence of the roof that was exposed to direct sunlight in summer, the temperature in the back of the hut increased, and the room temperature also increased, and the temperature did not decrease even at night, so you should have an uncomfortable and sleepless day. I must.

  Therefore, what is required is ventilation in the back of the cabin. If you can efficiently ventilate the heat and moisture that can easily be trapped in the back of the shed, you can improve the durability and comfort of your home.

  The present invention can meet such a demand, and the ventilation rain presser A according to the present invention is composed of at least two elongated members that can be combined vertically while maintaining a predetermined interval. In a state where they are vertically combined at a predetermined interval, the ventilation passage 4 communicates in the front-rear direction, and when it is installed at the junction between the lower house B and the outer wall C, the ventilation passage 4 communicates with the opening hole D formed in the vicinity of the joint between the lower house B and the outer wall C.

  As described above, when the ventilation rain presser A according to the present invention is installed in the joint portion between the lower house B and the outer wall C, the ventilation passage 4 is formed in the vicinity of the joint portion between the lower house B and the outer wall C. For example, as shown by the arrow in FIG. 4, the air in the attic of the lower house B can be released to the outside in communication with the hole D.

  It is desirable that the two long members are kept at a predetermined interval in the vertical direction by the intermediate member 3, and the three members are integrated by a connecting member such as a rivet. In this way, the two long members are always kept at a constant interval by the intermediate member, and the state is always maintained even after installation at a predetermined position.

  It is desirable that the ventilation passage 4 is constituted by a passage that is curved in the vertical direction. When the ventilation passage is in this way, the ventilation passage 4 is not in a straight line, so that rainwater does not flow into the ventilation passage 4 even if rainwater tries to enter the ventilation passage 4 from the outside. Therefore, rainwater does not enter the attic of the lower house B where the ventilation rain retainer A is installed.

  It is desirable that a windbreak plate 2c is formed on the front end side of the ventilation rain retainer A over the longitudinal direction. In this case, it is possible not only to prevent direct intrusion of rainwater from the opening portion on the front side of the ventilation rain presser A, but also to reduce wind resistance.

  It is desirable that a drain hole 2d is formed in the recess on the tip side of the ventilation rain retainer A. In this case, even if rainwater enters the recess of the ventilation rain retainer A, it flows out of the drain hole 2d, so that rainwater does not accumulate in the recess of the ventilation rain retainer A.

  According to the ventilation rain presser according to claim 1, when it is installed at the joint portion between the lower house B and the outer wall C, the ventilation passage 4 has an opening hole D formed in the vicinity of the joint portion between the lower house B and the outer wall C. The air in the attic of the lower house B can be released outdoors.

  According to the ventilation rain presser according to claim 2, the two long members are always kept at a constant interval by the intermediate member 3, and the state is always maintained even after installation at a predetermined position. The combined state can be maintained for a long time.

  According to the ventilation rain presser according to claim 3, even if rainwater enters the ventilation passage 4 from the outside, the rainwater does not flow into the interior through the ventilation passage 4. There is an effect that rainwater does not invade the attic of the house B.

  According to the ventilated rain presser of the fourth aspect, not only can rain water directly enter from the front opening of the ventilated rain presser A but also the wind resistance can be reduced. .

  According to the ventilation rain retainer of the fifth aspect, even if rainwater enters the recess, it flows out from the drain hole 2d, so that there is an effect that rainwater does not accumulate in the recess of the ventilation rain retainer A.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 1, the ventilation rain presser A according to the present invention is positioned between two long members 1 and 2 that can be combined vertically with at least a predetermined interval, and between both members 1 and 2. It consists of an intermediate member 3 for keeping the members 1 and 2 at a predetermined interval. The long members 1 and 2 and the intermediate member 3 can be made of, for example, a GL steel plate (galvalume steel plate). Moreover, those thickness can be made into about 0.35 mm.

Then, as shown in FIG. 3, the intermediate member 3 is positioned between the two elongate members 1 and 2, and both the members 1 and 2 are combined up and down at a predetermined interval, and in this state, a rivet or the like is coupled. It is integrated with members. The coupling members are not shown in detail, and the reference numerals are omitted. As described above, when the intermediate member 3 is positioned between the two long members 1 and 2, the two long members 1 and 2 are always maintained at a constant interval by the intermediate member 3. Even after the presser foot A is installed at a predetermined position, the state is always maintained.

  In this combined state, as shown by the arrows in FIG. 3, the ventilation passage 4 communicates in the front-rear direction (left-right direction in FIG. 3). As is clear from FIG. 3, the ventilation passage 4 is a passage that is not connected in a straight line but is curved in the vertical direction. In order to achieve this, for example, the following cases can be cited. The intermediate member 3 is substantially U-shaped as shown in FIG. 1, and a plurality of opening holes 3b, 3c are formed in the longitudinal direction at different positions in the height direction of the two vertical walls 3a, 3a. The vertical wall 3d is suspended downward from a horizontal portion located on the near side (right side in FIG. 3).

On the other hand, in the elongated member 1 located on the upper side, a plurality of opening holes 1b are formed in the longitudinal direction on the vertical wall 1a on the near side (right side in FIG. 3) in FIG. Further, in the long member 2 positioned on the lower side, a vertical wall 2a is formed in an upward direction with a predetermined distance from the vertical wall 1a from the horizontal portion on the front side (right side in FIG. 3) in FIG. In addition, the inclined wall 2b is formed obliquely upward from the horizontal portion on the back side (left side in FIG. 3) in FIG. 1 with a predetermined distance from the vertical wall 3a, and the upper edge of the inclined wall 2b is located on the upper side. It is located below the long member 1 so that a predetermined interval is formed between them.

  The two elongate members 1 and 2 and the intermediate member 3 positioned between the two members have such a structure, and by combining them as described above, as shown by the arrows in FIG. 3 in the left-right direction). As is clear from FIG. 3, the ventilation passage 4 is a passage that is not connected in a straight line but is curved in the vertical direction. And when this ventilation rain holder A is installed in the junction part of the lower house B and the outer wall C, the said ventilation channel | path 4 can be connected with the opening hole D formed in the junction part vicinity of the lower house B and the outer wall C. it can.

  A rising portion 1c extending obliquely upward at a predetermined angle (for example, 117 °) is located on the lower side of the long member 1 positioned on the upper side of the ventilation rain presser A. A windbreak plate 2c extending obliquely downward from a vertical wall 2a on the near side of the long member 2 is formed over the longitudinal direction. The windbreak plate 2c not only prevents direct intrusion of rainwater from the opening portion on the front side of the ventilation rain retainer A but also relieves wind resistance.

  Further, the recess on the tip side of the ventilation rain presser A, that is, the corner portion which is the lower edge portion of the vertical wall 2a formed upward from the horizontal portion on the near side (right side in FIG. 3) in FIG. A plurality of drain holes 2d and 2d are formed in the longitudinal direction. This drain hole 2d is for preventing rainwater that has entered the recess of the ventilation rain retainer A from flowing out and preventing the rainwater from collecting in the recess of the ventilation rain retainer A.

Next, the installation method of this ventilation rain retainer A is demonstrated in detail.
FIG. 4 is a cross-sectional view of the ventilation rain presser A installed in the lower house B, and FIG. 5 is a schematic perspective view thereof. Here, a case where the joint portion between the lower house B and the outer wall C is horizontal and the lower house B is installed in the lower house B that goes obliquely downward as the distance from the outer wall C will be described as an example. .

  As shown in FIG. 5, opening holes D and D are opened at a predetermined interval in the base plate E that is in the vicinity of the joint between the lower house B and the outer wall C. Then, the roofing indicated by the reference numeral F in FIG. 4 is applied on the base plate E, and the same position as the opening hole D is opened, and the rising portion thereof is made along the outer wall C. Next, a part of the roof tile G located at the uppermost stage is cut off according to the opening D.

  In this state, this ventilation rain presser A is placed in accordance with the opening hole D, and the fixing nail H is passed through the roof tile G from the roof tile E to attach the main ventilation rain presser A. The caps I and I are fitted to the left and right without gaps, and the joint portion of the ventilation rain presser A and the peripheral portion of the caps I are sealed. In this case, the rising portion 1c of the elongate member 1 located on the upper side of the present ventilation rain presser A is placed along the front side of the roofing F along the outer wall C.

  Next, the standard rain pressers J and J that are normally used are put on the caps I and I located on the left and right of the ventilation rain presser A. And the ventilation sheet K is stuck along the rising part 1c of the elongate member 1 located in the front side of the outer wall C among this ventilation rain clamp A, Furthermore, the siding L is constructed from the top, B The siding L covers the upper part of the joint between the outer wall C and the outer wall C.

  By such construction, the main ventilation rain presser A can be installed in the vicinity of the joint portion between the lower house B and the outer wall C, and the ventilation passage 4 is formed in the vicinity of the joint portion between the lower house B and the outer wall C. Communication with the hole D is possible. Therefore, the air in the attic of the lower house B can be discharged to the outside from the opening hole D through the ventilation passage 4 of the present ventilation rain retainer A as shown by the arrow in FIG.
