It would not be an exaggeration to say that adhesive joints have been an essential part of the construction industry for several decades now. However, a substantial disadvantage of bonded joints are the very strict requirements for adherence to the technological procedures defined by the manufacturers of assembly systems. Even a slight deviation from the recommended application steps can have a significant effect on the integrity of the entire system. In the research, five of the most common types of failure to comply with technological procedures in the realization of facade cladding were selected. The aim of the research project was to determine the extent to which a failure to adhere to technological procedures during facade construction can influence the effectiveness of the bonded joint. In construction practice, it is quite common during the implementation of a project that there are failures to comply with multiple requirements, or deviations from the prescribed procedures. For this reason, not only individual types of failure to comply with technological procedures were tested, but also their combinations. Altogether, 31 combinations of selected types of failure to comply with technological procedures were tested on one type of cladding. The adhesive joint was tested for shear strength and the adhesion of the adhesive to the substrate on a total of 352 samples. The results of the tests clearly confirm the hypothesis that failure to comply with technological procedures has a significant effect on the effectiveness of bonded joints. It is mainly the different combinations of failure to comply with technological procedures where the bonded joint loses effectiveness in the order of tens of percentage points.

工艺步骤对粘结接头力学性能的影响

毫不夸张地说，几十年来胶粘接头一直是建筑业的重要组成部分。但是，粘接接头的一个主要缺点是必须严格遵守装配系统制造商定义的技术程序。即使与建议的应用步骤稍有偏差，也会对整个系统的完整性产生重大影响。在研究中，选择了五种最常见的在实现外墙立面时不遵守技术程序的失败类型。该研究项目的目的是确定立面施工过程中未能遵守技术程序的程度会影响粘结接头的有效性。在建筑实践中 在项目的实施过程中，经常会遇到无法满足多项要求的情况，或者违反规定的程序。因此，不仅测试了不符合技术程序的个别类型，还测试了它们的组合。在一种类型的覆层上，总共测试了31种选定类型的不符合技术规程的组合。在总共352个样品上测试了胶粘接头的剪切强度和胶粘剂对基材的粘附力。测试结果清楚地证实了以下假设：不遵守技术规程会对粘合接头的有效性产生重大影响。
