AI Technical Summary
Traditional precast arch slab construction suffers from problems such as difficulty in ensuring airtightness, poor frame stability, and high risk of ring beam damage. In particular, it is difficult to meet the new regulations on airtightness and structural safety in large-span flat warehouse projects.
The design employs a synergistic approach of reverse tie rods and disc-buckle steel pipe top-mounted components. The reverse tie rod structure limits the deformation of the frame, while the disc-buckle steel pipe components offset the tensile stress, forming a composite control system of 'rigid connection + flexible offset'. Combined with the formwork setting of timber and foam board, airtightness is ensured.
It improved the stability and airtightness of the frame, reduced the amount of steel pipes used, shortened the construction time, prevented cracking of the ring beam, extended the service life of the silo, and reduced material costs.
