技术领域technical field
本发明涉及一种建筑施工方法，具体的说，是涉及一种装配式钢结构预制外墙板预制及施工方法。The invention relates to a building construction method, in particular to a prefabrication and construction method of prefabricated steel structure prefabricated exterior wall panels.
背景技术Background technique
在钢结构建筑中，围护外墙传统的做法为加气块砌筑后粘保温板和轻质板材安装后粘保温板的连接技术，这些施工技术工序繁琐，湿作业较多，并且由于材料的收缩特性较大，随着使用时间的延长，材料与钢梁间容易出现裂缝，特别容易出现漏水现象。近几年，随着装配式混凝土结构推广应用，外墙一般采用预制混凝土外墙，但是这种外墙间缝隙多采用干式连接，板间缝隙仅填充止水条和防水密封胶，在使用过程中围护成本较高，且存在漏水隐患。In steel structure buildings, the traditional method of enclosing the external wall is the connection technology of sticking insulation boards after aerated block masonry and light-weight boards are installed. The shrinkage characteristic of the material is relatively large. With the prolongation of the service time, cracks are prone to appear between the material and the steel beam, and water leakage is particularly prone to occur. In recent years, with the popularization and application of prefabricated concrete structures, the external walls generally adopt prefabricated concrete external walls, but the gaps between the external walls are mostly dry-connected, and the gaps between the panels are only filled with water-stop strips and waterproof sealants. The cost of enclosure during the process is high, and there are hidden dangers of water leakage.
