Steam curing device for assembling prefabricated concrete components

Abstract

The invention discloses a steam curing device for assembling concrete prefabricated components, which comprises a base frame, a steam inlet pipe, an air inlet pipe, a steam nozzle, a water nozzle and a driving motor. The air duct, the movable frame is installed in the stable seat, and the stable seat is fixed on the top of the base frame, and a horizontal plate is fixed on the side of the movable frame, and the horizontal plate is connected to the top of the side gear, and the side gear is fixed on the working shaft At both ends, control door panels are fixed on the working shaft, and the control door panels are attached to the material storage box. The steam curing device for the assembly of prefabricated concrete components adopts a new structural design, so that the steam discharge structure of the device will not make the steam contact with the small area of ​​the concrete, and water curing can be carried out at the same time as steam curing, ensuring that the cement in the concrete can be cured. The hydration reaction is carried out continuously, and fly ash can be added at the same time to improve the resistance of concrete to chloride ion penetration under steam curing conditions.

Description

technical field [0001] The invention relates to the technical field of concrete prefabricated components, in particular to a steam curing device for assembling concrete prefabricated components. Background technique [0002] Concrete prefabricated components are a kind of components used in construction engineering. Generally, there are precast concrete floor slabs, concrete box girders for bridges, precast concrete roof truss beams for industrial plants, culvert frame structures and precast concrete piles for foundation treatment, etc. Precast concrete Most of the components use formwork to be prefabricated in the factory, and after curing, they can be directly assembled and used during use. In the curing process of the formed concrete prefabricated components, steam curing is often used. Steam curing can effectively shorten the curing time of concrete and speed up. The construction schedule can also avoid the influence of low temperature on precast concrete components, and...
