Description

technical field [0001] The invention relates to the technical field of fastening tools, in particular to a fastening tool for bolts on the back of a building pipe fire-stop ring. Background technique [0002] With the rapid development of China's economy and the boom in construction and real estate, the exposed safety, environmental protection, energy and other issues have become increasingly prominent. Plastic pipes are widely used in various public and civil buildings, but plastic pipes are often easy to become a channel for fire propagation. The hole formed after the plastic pipe is burned by heat is like a chimney, so that the flame and smoke spread from the first floor along the pipe and Spread to another floor, or spread and spread from one room to another room, make the fire damage expand. Fire organizations around the world have come to a consistent conclusion that plastic pipes are the culprit for the spread and spread of fires. In the floor or wall, when a fire o...
