Wall mounting ventilation and manufacturing method

Disclosed are a ventilation device and a manufacturing method thereof. The ventilation device comprises: an outlet, a fixing portion, a cover portion, and a composite nonwoven fabric in which a pressed nonwoven fabric is attached to an entire upper surface of a felt nonwoven fabric. The manufacturing method of the ventilation device comprises: (S100) a fixing portion mounting step of inserting a fixing anchor into an upper end of one side of a vertical wall surface to mount a fixing portion; (S200) a composite nonwoven fabric insertion step of inserting an upper end of a composite nonwoven fabric cut to the predetermined width into a concave groove of the fixing portion; (S300) a pressed nonwoven fabric cutting step of cutting a pressed nonwoven fabric located on an upper surface of the felt nonwoven fabric to have a shape corresponding to the height of an outlet; (S400) an integration step of integrally forming the fixing portion with a cover portion; (S500) a ventilation path composition step of partially attaching the composite nonwoven fabric of which the upper end is inserted to a wall surface to be connected to a ventilation layer (ventilation path) of a waterproof floor; and (S600) a waterproof flooring material application step of applying a waterproof flooring material such that a front surface of the composite nonwoven fabric partially attached to the wall surface is integrally formed with the waterproof floor and wall surface. According to the present invention, a composite nonwoven fabric is inserted and fixed to a ventilation device having an outlet installed on an upper end of a vertical wall surface and capable of discharging a water vapor pressure and blocking, refluxing or discharging rainwater or cold air flowing backward, and thus it is possible to discharge a venting expansion pressure of water contained in a concrete substrate to the outside to prevent a defect that a waterproof floor swells up and a frost damage defect of a concrete substrate in the winter. 본 발명은 통기장치 및 제조방법을 개시한다. 본 발명은, 배출구가 구비되며 고정부 및 커버부로 형성되고, 펠트부직포 전체상부면에 압착부직포가 접착되는 복합부직포를 포함하며, 수직벽면 일측 상단에 고정앵커를 삽입시켜 고정부를 장착하는 단계(S100); 상기 고정부의 요(凹)홈에 소정 폭으로 절단된 복합부직포의 상단을 삽입하는 단계(S200); 상기 펠트부직포 상부면에 위치한 압착부직포를 배출구 높이와 대응하는 형상으로 절단하는 단계(S300); 상기 고정부과 커버부를 일체화시키는 일체화단계(S400); 상단이 삽입된 상기 복합부직포를 방수바닥의 통기층(통기경로)과 연결되도록 벽면과 부분적으로 부착시키는 통기경로 조성단계(S500); 상기 벽면에 부분적으로 부착시킨 복합부직포 전면이 방수바닥과 벽면과 일체화되도록 방수바닥재를 도포하는 단계(S600);를 포함하는 것을 특징으로 하며, 복합부직포를 수직벽면 상단에 설치되는 수증기압을 배출할 수 있고 역류하여 들어오
