Doemeun present design is installed outdoors relates to outdoor awnings that allow you to cover the sun and rain, it is out of the roof membrane lower uncomfortable because the vertical columns are installed on every conventional outdoor awning is the center, as well as the corners areas as well there was a problem being suffered injuries hit each vertical column in the entry process frequently, as well as doemeun therefore be provided with a plurality of vertical pillars picked many parts costs and buried each of the vertical pillars on the ground, and each vertical column the like to installing membrane roof on top is extremely cumbersome and picked lot of construction costs, a roof film is let be the air rising in the inner roof membrane discharged smoothly to the outside because the respective corner portion lower inclined high and the central portion such as the roof membrane mothayeo the air flow in and out of which air permeability is not smooth badly I bars, when the vertical post 10 of the upper front side and the upward slope of the upper portion of the front side edge of the top and back the other side edge of the upwardly inclined rod (11) installed to the roof membrane (21) to the upper rear other end embedded in it was At the same time, for supporting and installing the down-tilt rod 12 at a side upper front the other side to the upper rear side of the vertical post 10 downward ramp the front the other side edge of the lower and rear side edge lower part of the roof membrane (21) supporting the other hand, the vertical post top of 10 the upper front side and a side up-tilt rod (11) outer end and between the vertical columns 10, upper rear the other side and the other side upward slope rods 11, the outer end, and between the vertical pillars 10 of the installing the front the other side and the other down a downward slope rod top a horizontal supporting wire (13, 14) between the outer ends of the rear side and one side of downward slope rod 12 between the distal end and a vertical column 10 of the 12 in the present design, it characterized in that According to only one it is no obstacle is not on the bottom and outside of the vertical post 10 in the doemeun able to support the roof film 21 to significantly reduce the component costs and construction costs as well as the roof membrane (21) roof membrane ( 21) and out to the inside bottom it is to facilitate the, is not liable to cause various types of safety in and out the process, so allowing the air inside of the roof film 21 can be smoothly discharged to the outside can significantly enhance the permeability the effects of being able thereby obtained.
