Regarding the blowing force on the tent, as shown in the tent blowing force comparison table in Figure 12, the tent with the original gable roof type has the highest blowing force, followed by the tent with the trapezoidal roof type (without sheet cover), and the tent with the trapezoidal roof type (without sheet cover) Trapezoidal roof types (with sheet covers) have the least amount of blowing force on tents.

Regarding the improvement rate, compared with the conventional gable roof type, the trapezoidal roof type is 74.5% without a cover, and 72.4~66.0% with a cover, and the upward blowing force is reduced by about 45%.

In addition, regarding the upward blowing force of the wind, as shown in the comparison table of the upward blowing force of the wind in Figure 13, the upper blowing force of the traditional gable roof type tent is the largest, followed by the trapezoidal roof type (without sheet cover) Blowing force on the tent, and the least blowing force on the trapezoidal roof type (with a sheet cover) tent.

In addition, the trapezoidal roof type (without sheet cover and with sheet cover) will fall only at a wind speed of 13m/s, compared to the conventional gable roof type which would fall over at a wind speed of 10m/s.

The present invention has the following effects

1. In the cross-wind-resistant field tent of the present invention, since the vertical cross-sectional area of the tent is reduced, the wind pressure caused by the cross-wind is also reduced, so that a field tent that can cope with a sudden strong cross-wind is realized.

2. The crosswind-resistant field tent of the present invention can build a tent with high safety, long depth and large floor area because the height of the tent is lowered.

3. The crosswind-resistant field tent of the present invention can reduce the height of the tent, so the chances of using the field tent will increase in places where there are buildings on the river bank under the bridge and where the field tent cannot be used normally.

4. In the field tent of the crosswind response type according to the present invention, when sudden wind or strong wind blows into the tent, the ventilation opening consisting of one or more adjacently arranged holes on the roof of the tent and the side surface are provided. The cover on the outside of the air vent will be automatically opened, thereby preventing the tent from collapsing and floating due to sudden wind or strong wind, thereby reducing the harm to people.

5. The left and right edges of the cover of the air vent are fixed on the tent through a waterproof sheet that can be freely stretched and contracted by folding. Inflow at both ends.

6. Due to the tension of the tent part remaining between the holes, the shape of the tent is maintained, so there is no such problem that the tent near the air vent sags, and it is possible to prevent the cover placed on the outside of the air vent from sinking into the tent.
