一种轻钢龙骨装配式复合墙板的防水性能试验研究
Experimental Study on Waterproof Performance of a New Light Steel Keel Prefabricated Composite Wall Panel
本文聚焦一种具有横向企口构造的轻钢龙骨装配式复合墙板,展开防水性能试验研究。首先设计足尺试件,开展风压下淋水试验,参照相关标准采用稳定加压法,模拟不同风荷载与风雨共同作用,运用目测法、化学试纸法观测墙体本身水密性;之后针对不同企口间隙的墙板进行淋水试验,运用目测法、化学试纸法和红外热成像法观测横缝渗漏情况。试验结果显示:该复合墙板水密性能优良,水密性能指标达3 000 Pa,满足相关标准要求;横缝间隙影响墙面渗漏,间隙宜控制在2 mm以下;红外热成像检测法能有效判断墙板拼缝是否渗漏,当横缝与周围墙板温差大于2.5 ℃时可判断渗漏,且与其他检测方法结果吻合。本研究为完善复合墙板构造设计提供了试验依据。
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.
