PC Curtain Wall Handbook

PC curtain walls that create the scenery of high-rise buildings and cityscapes.

PC curtain walls are precast concrete products that incorporate the curtain wall construction method. A curtain wall is a wall that separates internal and external spaces like a curtain, without bearing the load of the building itself, except for structural walls. Precast concrete refers to concrete that is manufactured in a factory rather than at the construction site. By manufacturing exterior wall components in advance at the factory, it becomes easy to ensure various performance requirements for exterior walls without being affected by weather, leading to stable quality and improved building precision. Additionally, since installation can be done from the inside, it allows for construction without scaffolding, and enables continuous construction of the structural framework, flooring, curtain wall, and interior work, making the curtain wall construction method essential for shortening construction periods in modern high-rise building projects. PC curtain walls excel in various performance characteristics such as fire resistance, thermal insulation, and soundproofing, which are inherent to concrete, allowing for the required performance to be achieved at a low cost. Furthermore, there are many options for high-quality finishes that are aesthetically pleasing and durable. In particular, by using architectural concrete or decorative formwork to create patterns, it is possible to create a unique facade that matches the design image of the building.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.
