Wind-rain simulation test apparatus and wind, rain and wind-rain comprehensive simulation test methods of building envelope system

Abstract

The present invention discloses a wind-rain simulation test apparatus of a building envelope system. The apparatus comprises a wind source supplying system, an artificial rainfall simulation system and a testbed. The wind source supplying system is on one side of the testbed. The artificial rainfall simulation system is above the testbed. A test-piece installation platform is installed on the testbed, and a leaked rainfall collector is disposed below the test-piece installation platform. The present invention further provides wind, rain and wind-rain comprehensive simulation test methods for abuilding envelope system. The test apparatus can be used for installing a to-be-tested piece on the test-piece installation platform, the wind source supplying system is used for simulating natural wind, the artificial rainfall simulation system is used for simulating rainfall, and the leaked rainfall collector can collect a rainfall leaked by the to-be-tested piece. A wind simulation test methodis used for detecting wind-resistant performance of the to-be-tested piece, a rain simulation test method is used for detecting rain-resistant performance of the to-be-tested piece, and a wind-rain comprehensive simulation test method is used for detecting performance of the to-be-tested piece in a wind-driven rain environment.

Description

technical field [0001] The invention relates to the technical field of detection of building envelope systems, in particular to a wind and rain simulation test device and method. Background technique [0002] With the rapid development of modern buildings, the roofs of more and more large public buildings are built with new roof systems. In order to meet the requirements of indoor comfort and energy saving, the building envelope system uses a large number of functions such as ventilation skylights, ventilators and shutters. According to the ventilation or lighting design requirements of the building, the form of these functional auxiliary structures is determined by comprehensively considering the local climate conditions, dominant wind direction, building height, temperature difference between intake and exhaust air, ventilation volume, and indoor production process characteristics. Due to the limited means of testing the structural safety performance of wind and rain resis...
