AI Technical Summary
When adding fireproof and blast-resistant walls to existing buildings, how can we ensure the stability and safety of the walls under non-explosive conditions, while ensuring that the fireproof and blast-resistant walls do not affect the calculation assumptions of the main structure in the event of an explosion, and avoid damage to the main structure and equipment caused by the collapse of the walls?
Multiple sets of blast-resistant walls are connected to the existing building via a connection device. The connection device includes a cylinder and a damping mechanism. The cylinder contains damping fluid and a spiral structure. During an explosion, the sliding rod disengages, and the blast-resistant wall separates from the main structure. The blast-facing side uses PVA fiber concrete and the blast-backing side uses steel fiber concrete, which respectively form pores and enhance the bonding effect at high temperatures.
To improve the stability and safety of blast-resistant walls under non-explosive conditions, the blast-resistant walls are separated from the main structure during an explosion, ensuring that the calculation model of the main structure remains unchanged, while preventing concrete cracking and secondary damage, and improving construction efficiency.
