预制混凝土夹芯保温外墙板质量现状及偏差控制分析
|
摘要
预制混凝土夹芯保温外墙板作为装配式混凝土结构的重要构件,其生产工艺及质量控制对结构整体的质量及性能具有重大影响,以某大型预制构件厂2015—2017年的4 400块预制混凝土夹芯保温外墙板检测数据为基础,得到其外观质量、外形尺寸、预埋预留、门窗洞口、钢筋等方面的质量现状及各质量指标偏差分布。并对2017年的检测数据进行非线性拟合,得到各检验项偏差值分布函数及规律,其结果可为制定预制混凝土夹芯保温外墙板各质量控制指标允许偏差提供参考。
As an important prefabricated member of prefabricated concrete structure,the precast concrete insulated sandwich panel has great influence on the quality and performance of the whole structure. Based on the test data of4 400 precast concrete insulated sandwich panels manufactured by a large prefabricated component factory in 2015-2017,the quality status and deviation distribution of appearance,size,embedded parts,opening of doors and windows and reinforcement were obtained. The nonlinear fitting of the test data in 2017 was used to get the distribution function and law of the deviation values of each test item. The results can provide a reference for the allowable deviation of the quality control indicators of the sandwich insulation panel.
