Experimental Study on Waterproof Performance of a New Light Steel Keel Prefabricated Composite Wall Panel
摘要
Abstract
This paper presents an experimental study of the waterproof performance of a light steel keel prefabricated composite wall panel with a horizontal tongue-and-groove structure.Full-scale specimens were designed,and water spray tests under wind pressure were carried out.The stable pressurization method was adopted following relevant standards to simulate different wind loads and the combined action of wind and rain.Visual inspection and chemical test paper method were used to observe the water tightness of the wall itself.Water spray tests were conducted on wall panels with different tongue-and-groove clearances,and visual inspection,chemical test paper method,and infrared thermography were used to observe the leakage at the cross joints.The test results show that the composite wall panel has excellent water tightness,with a water tightness performance index reaching 3000 Pa,meeting the requirements of relevant standards.The clearance of the cross joints affects the leakage of the wall surface,and the clearance should be controlled below 2 mm.The infrared thermography detection method can effectively determine the leakage of the wall panel joints.When the temperature difference between the cross joints and the surrounding wall panels is greater than 2.5℃,leakage can be detected,and the results are consistent with those of other detection methods.The research provides an experimental basis for improving the structural design of composite wall panels.关键词
