This utility model relates to the field of indoor air purification technology and discloses an ultra-low energy consumption building indoor air purification device, including a mounting base, connecting rod, air pump, power components, gas absorber, and cleaning tray assembly. The cleaning tray assembly consists of a cleaning tray shell and a cleaning tray top plate that are detachably connected. Through the snap-fit ​​structure of the clip and snap-fit ​​post, and the pre-positioning cooperation of the positioning ring and the positioning groove, the cleaning tray shell and the cleaning tray top plate can be quickly disassembled and assembled, facilitating the inspection and maintenance of the internal components of the cleaning tray assembly, further reducing operation steps and saving maintenance time. Secondly, through the sliding cooperation of the guide block and the guide groove, combined with the characteristic of the limit block automatically retracting under compression, the gas absorber can be quickly installed and disassembled without the entire cleaning tray being disassembled, solving the problem of complex operation in the prior art that "the entire cleaning tray needs to be disassembled to replace the absorbent material," and significantly improving maintenance efficiency.

This invention relates to emergency reinforcement blocks, individual units, and emergency sparse-density reinforcement methods for beam fractures, belonging to the field of building structure technology. When beam components are subjected to heavy hanging loads or their function changes without design verification, there is a lack of quantitative emergency remedies for beam reinforcement. The invention utilizes a hollow steel box comprising a box body with multiple hollow holes for concrete pouring. The top of the hollow steel box has an arc-shaped notch, on which a recessed arc-shaped piece is integrally connected. The outer wall of the arc-shaped piece is an assembly wall. The top surface of the hollow steel box has two insertion ports, and multiple folded plates are inclinedly positioned between the front and rear folded-line notches. The emergency sparse-density reinforcement method in this invention involves a quantitative configuration process based on the width between two broken rebar ends and the fracture depth in the beam fracture area, specifying the number of emergency reinforcement units, the number of subsequent rebars, and their connection positions.
