AI Technical Summary

Technical Problem

When using existing precast concrete component joint sealing devices, uneven application of sealant can lead to incomplete sealing and affect the effectiveness of the device.

Method used

A sealing device for joints in precast concrete components was designed. It uses components such as joint connecting plates, hoses, piston rods and rotating shafts. By rotating the polygonal block, the rotating shaft and the extrusion protrusions are driven to achieve uniform discharge of sealant. The precast concrete slab is fixed by a blocking plate and a spring spring to ensure sealing effect and easy connection.

Benefits of technology

It achieves uniform application of sealant, improves the sealing effect of joints, prevents gaps from appearing, and also improves the ease of fixing and connecting precast concrete slabs.
