Butt joint connecting structure of precast concrete components
The invention discloses a butt joint connecting structure of precast concrete components. The connecting objects are a component I and a component II which are closely connected with each other through a concave pit/a groove and a protrusion which are matched with each other in shape and size and paved with a cushion ply, and meanwhile a rear sealing troughed belt is formed between the two precast concrete components; a connecting mode of 'a longitudinal bar-a sleeve-a connecting rod-a sleeve-a longitudinal bar' is adopted for longitudinal bar connection, connection between the connecting rod and sleeves at the two ends can achieve a prestressed connection effect through a difference between pitches at the two ends. According to the butt joint connecting structure of the precast concrete components, the problems that in existing cast-in-place connection and bed mortar connection, time for forming bearing capacity on the joint is too long, assembly schedule is affected, the difficulty for transporting and protecting longitudinal bars to be connected is great, and minimum clear distance of grout sleeves and thickness of a protection layer is difficult to be guaranteed are solved, and meanwhile the prestressed connection is achieved.
