浅议建筑物结构的加固与改造

Discuss on the Reinforce and Transformation of the Building Structure

喷射混凝土是借助喷射机械,利用压缩空气或其他动力,将按一定配合比的水泥、砂、石子及外加剂等拌和料,通过喷头喷射到受喷面上,在较短时间内凝结硬化而成型的混凝土,达到补强加固的目的。这种加固方法具有施工方便,施工速度快,不需要模板,施工成本低等特点。介绍了混凝土建筑物加固改造中目前常用的施工技术,为新、旧建筑物的加固改造提供了可供选择的几种施工方法。

Shotcrete is a method with the spray machine through the use of compressed air or other power and a certain mix of cement,sand,gravel and additives such as mixing materials,sprays to be sprayed through the nozzle surface,hardens in a relatively short period of time and forms the shape of the concrete to achieve the purpose of reinforcement. This strengthening method has the features of convenient for construction ,high construction speed, no template,low cost. The construction technology in the reinforcement of concrete structures is introduced which provides several alternative construction methods for new and old buildings retrofitting.
