Description

一种钢结构外墙板连接装置 A connection device for steel structure exterior wall panels

技术领域 technical field

本实用新型属于建筑构件连接技术领域,更具体地说,是涉及用于钢结构建筑的一种外墙板快速连接装置。The utility model belongs to the technical field of connection of building components, and more specifically relates to a quick connection device for exterior wall boards used in steel structure buildings.

背景技术 Background technique

钢结构广泛应用于厂房、办公楼、超市等建筑物,随着国家对住宅产业化的需求,钢结构住宅在全国各地迅速发展起来。Steel structures are widely used in factories, office buildings, supermarkets and other buildings. With the country's demand for housing industrialization, steel structure housing has developed rapidly across the country.

目前的钢结构建筑外墙板安装大多用内嵌法或外挂法。其中内嵌法安装的墙板容易产生冷、热桥的问题,因此不符合钢结构建筑节约资源的发展方向。外挂法大多采用在墙板上设置预埋件,在施工现场与钢结构主体焊接固定,但是这种节点连接方法不仅造成现场焊接作业量大、装配化程度低,而且与钢结构焊接固定从而使墙板不具备产生自由位移的能力,加上钢结构建筑外墙板多为轻质墙板,因此在地震等外力下墙板容易因无法适应钢结构主体的变形而破坏。因此目前的外墙板连接方法无法充分发挥钢结构建筑的优势。Most of the current steel structure building exterior wall panels are installed using the embedded method or the external hanging method. Among them, the wall panels installed by the embedded method are prone to cold and thermal bridge problems, so they do not conform to the development direction of steel structure buildings to save resources. Most of the external hanging methods use embedded parts on the wall panels, which are welded and fixed with the main body of the steel structure at the construction site. Wall panels do not have the ability to generate free displacement, and most of the exterior wall panels of steel structure buildings are lightweight wall panels, so the wall panels are easily damaged due to the inability to adapt to the deformation of the main steel structure under external forces such as earthquakes. Therefore, the current method of connecting external wall panels cannot give full play to the advantages of steel structure buildings.
