AI Technical Summary
In the current precast staircase manufacturing process, accessories such as junction boxes and conduits are prone to displacement or being encased in concrete during the pouring of concrete, which is difficult to correct.
The system employs a connecting component, an adsorption component, and a fixing component. The fixing component securely connects the conduit to the junction box, while the adsorption component allows the housing and cover to adhere to each other, ensuring the junction box is fixed in the required position and preventing displacement or being encased in concrete.
It effectively prevents junction boxes and conduits from shifting or being encased in concrete during later stages of construction, simplifies the correction process, and improves construction accuracy.
