Description

Technical Field

[0001] The utility model belongs to the technical field of structural column maintenance equipment, and specifically relates to an energy-saving maintenance device for a structural column. Background Art

[0002] With the development of construction technology, reinforced concrete buildings have become the mainstream building structure. In reinforced concrete structures, structural columns are vertical load-bearing components that bear the loads from beams and slabs in the structure and transmit the loads to the foundation. Like other concrete structures, after pouring, in order to avoid cracking due to excessive shrinkage of concrete, it is necessary to carry out thermal insulation and moisture maintenance on the external formwork or the structural column itself to prevent cracking of the structural column. In the maintenance process of the structural column, since the structural column is a vertical concrete column, the water spraying maintenance method has problems such as uneven water spraying and discontinuous maintenance, which makes the water spraying maintenance method not suitable for the maintenance of the structural column. Although curing agent maintenance and film maintenance can achieve better maintenance effects, since the curing agent maintenance needs to be evenly applied and the film is easily damaged during film maintenance, these two maintenance methods are not effective in maintaining the structural column. Therefore, how to maintain the structural column has become an urgent problem to be solved in this field.

[0003] In order to solve the above problems, a utility model patent with announcement number CN212129982U discloses an intelligent curing bag for concrete structural columns. The curing bag is fixed to the outside of the structural column through a curing bag lock zipper, and an integrated controller is used to connect a built-in water supply hose through a water supply hose. The curing bag is used to perform intelligent curing on the concrete structural column. When the humidity exceeds a predetermined value, the built-in water supply hose is used to automatically replenish water and moisturize the concrete structural column to meet the curing requirements. However, when the curing bag is used, there are still problems such as:

[0004] 1. The above-mentioned curing bag needs to be put on the outside of the concrete column as a whole. During use and fixation, it needs to be fixed with a curing bag lock zipper, which is inconvenient to fix and install; after the curing bag is filled with water, its deadweight becomes larger, and the curing bag lock zipper has safety hazards during use and is difficult to open;

[0005] 2. When the above-mentioned curing bag is used, due to its fixed size, it can only be used for the curing of structural columns of one diameter, and its application range is small, and it is not convenient to use it on structural columns with multiple diameters;

[0006] 3. The above-mentioned curing bags cannot realize the recycling of water, which easily causes waste of water resources and is not convenient for achieving energy-saving needs;

[0007] Therefore, the utility model designs an energy-saving maintenance device for structural columns to solve the problems existing in the above-mentioned prior art. Utility Model Content
