The utility model relates to the technical field of abandoned
cave dwelling reconstruction, and discloses a structure reinforcing device for abandoned
cave dwelling reconstruction, which comprises a
cave dwelling support frame, reinforcing components are uniformly distributed in the
cave dwelling support frame, and a handheld rod is fixed at the top end of a sealing plate. The ventilation pipes are assembled on the two sides and the top of the outer wall of the outer heat preservation plate and used for follow-up ventilation work, the filter box is arranged on the right side of the
cave dwelling supporting frame, the filter plate is installed in the filter box, and meanwhile the positioning base can be fixed to the bottom in the filter box. The filter
cartridge is filled with needed
activated carbon or
bamboo charcoal, then a worker holds the handheld rod and rotates the handheld rod, and at the moment, the threaded connection block is matched with the internal threads on the inner wall face of the filter
cartridge to complete threaded locking, so that after the fan is started to work and supply air,
airflow can be filtered and deodorized through the positions of the filter plate and the filter
cartridge; in this way, the overall
airflow circulation effect is well improved in the working process, and the ventilation convenience is improved.
