House Installation Related to Prefabricated Panels

The expression 'house installation of prefabricated panels' may be misleading. Typically, prefabricated panels were used as floor slabs in early buildings. Nowadays, discussions more often focus on the renovation of existing houses with prefabricated panel structures. If the intention is to inquire about the relationship between elevator installation in houses and prefabricated panel structures, there are numerous difficulties in adding elevators to old prefabricated panel brick-concrete houses.

Poor Structural Integrity

The prefabricated panels in old prefabricated panel brick-concrete houses are simply placed on the walls like jigsaw pieces, lacking firm connections between the panels themselves and between the panels and the walls. This structural form results in relatively poor overall integrity of the house. During the process of elevator installation, operations such as wall chiseling and beam removal are required, which will further damage the structural integrity of the house. For example, the originally loose connections, when subjected to external force damage, may significantly reduce the stability of the house and even trigger serious safety issues such as local collapses.

Difficulties in Coordination between Old and New Structures

Adding an elevator requires the addition of some structural components, such as elevator shafts. It is difficult for these new structures to work well in coordination with old prefabricated panel brick-concrete houses. Due to differences in materials, construction techniques, and design standards between the two, problems will arise in force transmission and deformation coordination. For instance, under external forces such as earthquakes, the old and new structures may deform differently, leading to cracks or even damage at the connection points, affecting the normal use of the elevator and the safety of the house.

Fire Safety Hazards

Old prefabricated panel brick-concrete houses may already have some deficiencies in fire safety. The addition of an elevator may exacerbate these issues. The elevator shaft may change the original ventilation and evacuation routes of the house, affecting smoke exhaust and personnel evacuation in case of a fire. Moreover, the newly added electrical wiring and equipment may also increase the risk of fire. If fire safety facilities are not properly equipped, the consequences of a fire will be unimaginable.
