膨胀螺栓是一种高效新型的紧固件。近几年来,国内逐步在电器线路、暧通管道和设备基础等安装工程上应用。它具有施工简便、安装位置准确等优点。在土建施工中、不需要采取以往预留孔洞或预埋螺栓的习惯做法,尤其对老厂的技术改造和设备的调整安装有现实意义,可以减少原有建筑物的破坏程度,是目前比较理想的一种新工艺。我们通过实验和现场实测,在取得实验数据的基础上,成功地在冷库无梁楼板上安装了
Expansion bolts are a new type of efficient fasteners. In recent years, the domestic gradually applied in the installation of electrical wiring, heating pipes and equipment and other infrastructure. It has the advantages of simple construction, accurate installation location and so on. In civil construction, it is not necessary to adopt the conventional practice of reserving holes or embedding bolts in the past. In particular, it is of practical significance for the technological transformation of old plants and the adjustment and installation of equipment to reduce the degree of destruction of the existing buildings, which is now ideal A new technology. Through experiments and field measurements, we obtained the experimental data and successfully installed the freezer slab
