Embodiment

[0082] like Figure 1-3 As shown, a steel structure anti-collapse scaffolding for ventilation shafts in a civil air defense project includes a steel structure scaffolding and a cover plate structure.

[0083] The steel structure scaffolding includes a support frame 2 , a main support rod 3 , a secondary support rod 4 , a rain tile 5 , and a protective railing 6 . figure 1 In the top view of the steel structure scaffold of this embodiment, in order to clearly show the positional relationship between the support frame 2 and the main support rod 3, the auxiliary support rod 4 and the rain-proof tile 5 are not shown.

[0084] like figure 1 As shown, at least two supporting frames 2 are arranged side by side. For the case where the lateral span is less than or equal to 2100mm, two supporting frames 2 can be arranged side by side; for the case where the lateral span is greater than 2100mm, multiple supporting frames need to be arranged side by side. The long sides of the support...

Abstract

The invention discloses a ventilation shaft assembly type steel structure anti-collapse shed frame in civil air defense engineering, the ventilation shaft assembly type steel structure anti-collapse shed frame in civil air defense engineering comprises a steel structure shed frame and a cover plate structure, a ventilation shaft is provided with a waterproof retaining wall exposed out of an outdoor terrace, the waterproof retaining wall is provided with a pre-embedded assembly, and in wartime, the waterproof retaining wall is provided with an anti-collapse assembly; the steel structure shed frame is installed on the waterproof retaining wall through the pre-embedded assembly, and at ordinary times, the waterproof retaining wall is provided with a cover plate structure used for protecting the pre-embedded assembly and shielding the ventilation shaft. The device can be put into use as soon as possible in wartime, and the influence on the appearance of a city at ordinary times can be reduced.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to an anti-collapse scaffolding of a ventilation shaft assembled in a civil air defense project. Background technique [0002] In civil air defense engineering, conventional weapons and nuclear weapons in wartime cause air pollution, water vapor and harmful and explosive gases emitted from the stratum, exhaust gas emitted when internal combustion engines are working, water vapor and carbon dioxide emitted by workers when they breathe, and will accumulate in large quantities up, forming an unsafe factor. To ensure safety, ventilation facilities are required. A ventilation shaft is a type of ventilation facility. One end of the ventilation shaft is connected to the space of the underground building, and the other end of the ventilation shaft is provided with a waterproof retaining wall exposing the outdoor floor. [0003] According to the requirements of "Code...
