≪Action≫
Next, the operation of the deaeration structure according to the embodiment of the present invention will be described.
The roof base 3 shown in FIG. 1 may be in a state where the building structure B gets wet excessively during the construction due to rain or the like and is excessively wet. As shown in FIG. 1, when the deaeration passage forming member 4 and the laminate L are provided on the flat upper surface 3a of the roof base 3 in a state containing water, the roof base 3 remains moist. It becomes a state.

  Moisture contained in moisture such as moisture in the roof base 3 is evaporated by solar heat of sunlight or the like and enters the first deaeration passage 11. The water, water in the first degassing passage 11 and the like are vaporized by being warmed by the heat of the sunlight, and the water vapor pressure increases and diffuses and rises.

  As shown in FIGS. 2 and 3, the vaporized gas in the first deaeration passage 11 is guided by the inclined ceiling surface 4c of the deaeration groove 4a, and reaches the top 4g along the ceiling surface 4c. It flows in the horizontal direction (arrows a and b directions) and enters the decylinder 81 through the first communication port 81d at the top 4g. The gas rises upward in the decylinder 81 (in the direction of arrow c), passes through the exhaust passage 13, and is exhausted into the atmosphere from the opening at the lower end of the rainwater cover 82.

  Thus, in the deaeration passage forming member 4, the ceiling surface 4c of the deaeration groove 4a is inclined upward toward the first deaeration device 8, so that the vaporized fluid rises to a higher position. For this reason, the fluid in the first degassing passage 11 can be guided smoothly to the first degassing device 8 and sent smoothly.

  Further, the deaeration structure 1 includes the second deaeration device 9 in the upright portion 3e, so that the fluid that has been generated from the roof base 3 and entered the portion near the upright portion 3e in the first deaeration passage 11 Can be released from the second deaeration device 9 into the atmosphere. For this reason, the deaeration structure 1 can smoothly release the fluid in the first deaeration passage 11 into the atmosphere by the first deaeration device 8 and the second deaeration device 9.

Thus, when the fluid evaporated from the water contained in the roof base 3 flows into the first deaeration passage 11 on the roof base 3, the first and second deaeration devices 8, 9 is released into the atmosphere, so that it can be prevented from staying in the first degassing passage 11 or the like.
Therefore, the deaeration structure 1 eliminates the fact that the moisture contained when the roof foundation 3 gets wet with rainwater or the like remains in the first deaeration passage 11 or the like, and the first deaeration device. The two degassing devices 8 and 9 can be efficiently discharged into the atmosphere and degassed. For this reason, it is possible to positively reduce the humidity of the roof base 3 and prevent the roof base 3 from being moldy or the roof base 3 from decaying.

  In addition, when the waterproof base 5 contains moisture, the moisture is evaporated by the heat of sunlight or the like and enters the second deaeration passage 12. The second deaeration passage 12 is a waterproof base provided on the upper surface 4d of the deaeration passage forming member 4 that is inclined so as to rise upward toward the hill 4e where the first deaeration device 8 is installed. 5 and the ventilation sheet 6, and is inclined so as to rise upward along the upper surface 4 d of the deaeration passage forming member 4.

  For this reason, the moisture in the second deaeration passage 12 flows smoothly in the lateral direction (arrow d direction) toward the second communication port 81e of the decylinder 81 of the first deaeration device 8, so that the second deaeration It is possible to prevent the fluid from staying in the passage 12. As a result, it is possible to eliminate the occurrence of mold, dew condensation, and problems such as the swelling phenomenon in the waterproof base 5 or layer.

  The first deaerator 8 communicates the decylinder 81, the first communication port 81 d that communicates the hollow part 8 c and the first deaeration passage 11, and the hollow part 8 c and the second deaeration passage 12. And a second communication port 81e. For this reason, the 1st deaeration apparatus 8 can discharge | release the fluid in two deaeration passages in air | atmosphere with one decylinder 81. FIG. As a result, the first deaeration device 8 can simplify the structure, reduce the number of parts and the number of assembly steps, and reduce the cost.

Further, since the first deaerator 8 is covered with a rainwater cover 82 so as to form the exhaust flow path 13 above the upper opening 81f of the decylinder 81, rainwater or the like enters from the upper opening 81f. It is possible to prevent the roof base 3 from being moistened through the decylinder 81. For this reason, the 1st deaeration device 8 can always exhaust the gas from the exhaust flow path 13 in the rainwater cover 82 to the atmosphere efficiently, and can dry the inside of the roof base 3 and the laminated body L.
Moreover, the rainwater which fell on the rainwater cover 82 and the waterproof layer 7 flows in the drainage gradient on the waterproof layer 7 toward the left-right end direction (arrow f direction).

  Thus, the deaeration structure 1 is such that the ceiling surface 4c of the deaeration groove 4a of the first deaeration passage 11 and the second deaeration passage 12 are inclined upward toward the decylinder 81. The fluid in the first and second degassing passages 11 and 12 can be smoothly discharged through the first degassing device 8. As a result, even if the number of first degassing devices 8 arranged on the rooftop 2 is reduced as compared with the conventional case, the fluid in the first and second degassing passages 11 and 12 can be discharged well to perform degassing. it can.

  Further, the deaeration structure 1 includes a deaeration member 91 provided in the upright portion 3e, a rising sheet 92 that covers the communication groove 91a of the deaeration member 91, and the first and second deaeration passages 11 and 12. A second deaeration device 9 having a deaeration member passage 14 communicating therewith is provided. For this reason, the deaeration structure 1 can discharge the fluid close to the upright part 3e in the first and second deaeration passages 11 and 12 from the second deaeration device 9 into the atmosphere. 2 The fluid in the deaeration passages 11 and 12 can be discharged more smoothly.
