The utility model relates to a gas
tunnel construction technical field, especially a kind of gas tunnel's non-moving fire supporting
steel frame, including section
steel frame, connecting rod and anchor
pipe, multiple section steel frames are arranged along the length direction of tunnel interval;Positioning sleeve is equipped on section
steel frame, connecting rod both ends have
elbow section, two
elbow sections are inserted into the positioning sleeve of adjacent two section steel frames respectively;It further includes the
gasket of setting in section steel frame lower part, anchor
pipe is located at the both sides of section steel frame, and anchor
pipe is detachably connected on
gasket.The
welding connection mode of traditional supporting steel frame is improved, the
elbow section of connecting rod is inserted into positioning sleeve, anchor pipe is detachably connected on
gasket,
welding operation is not used between adjacent section steel frames, between section steel frame and anchor pipe, the technical difficulty of gas tunnel non-moving
welding operation is solved, explosion or
fire risk, such as
safety risk, existing in initial supporting steel frame in gas tunnel is effectively avoided, and the construction safety of gas tunnel is protected.
