The invention discloses a device for testing the wind resistance of a large-span cantilever awning. The device comprises a rotating disc, the two sides of the upper end of the rotating disc are provided with main buildings, an awning model is disposed between the main buildings, the awning model is supported through an awning frame and is connected with the main buildings through a connecting support, a water drainage pipe is arranged at the bottom end of the connecting support, a 45-degree water spraying device is arranged above the awning model, eight air exhaust devices in different directions are arranged on the outer sides of the main building and the awning model in a surrounding mode, the air exhaust devices in the eight different directions are arranged every 45 degrees, so that wind resistance tests in different directions are achieved, the rainfall amount and surrounding main buildings have large interference on the wind load of the awning model, so that the wind resistance performance of the awning model can be obtained by controlling the wind pressure and the water amount to be matched with the wind direction working condition, the wind resistance performance of the awning model can be obtained through the expressive force of the awning model under different conditions, and therefore comprehensive evaluation and improvement are achieved.
本发明公开了一种大跨度悬挑雨篷抗风性能测试装置，包括旋转转盘，所述旋转转盘上端两侧设置有主要建筑物，所述雨蓬模型设置于主要建筑物之间，其中雨蓬模型通过蓬架进行支撑，并通过连接支架与主要建筑物相连接，所述连接支架底端设置有排水管，所述雨蓬模型上方设置有45度喷水装置，而主要建筑物与雨蓬模型外侧环绕设置有八个不同方向的排风装置，该八个不同方向的排风装置每45度设置一个，以达到不同方向的抗风试验，并且降水量以及周边主要建筑物对雨蓬模型的风荷载也具有较大的的干扰，因此控制风压及水量配合风向工况能够获得雨蓬模型的抗风性能，本发明通过不同情况下的雨蓬模型表现力，可以获得其抗风性能，从而达到综合性评估及完善。
