Discussion on firewalls in the GB50016-2014 (2018) Code for Fire Protection Design of Buildings
Thread Content
Due to space constraints, the outer edge of the newly constructed Class B factory is only 9 meters away from the outer edge of the existing Class E factory, which fails to meet the requirement of 10 meters between Class B and Class E factories as specified in Table 3.4.1 of the building fire protection codes. In accordance with the note in Table 3.4.1, the exterior wall of the new Class B factory should be a fire wall; moreover, per Article 6.1.5 of the building fire protection codes, it is permissible to install non-removable windows as well as Class A fire-resistant doors and windows with automatic closing functions on this fire wall. How should one handle such problems in practice?
Sure, you can take a look at clause 3.4.8; it’s possible that no changes will be needed, as the current situation already complies with the standards
However, as indicated in the illustrations of the GB50016-2014 (2018) Code for Fire Protection Design of Buildings, it is not clear. The illustrations from the 2014 version explicitly state that openings are not allowed, but the 2018 version does not clearly specify whether openings are permitted or not, which is why such confusion arises. Thank you for your participation and reminder. The key issue is whether there will be any problems with the subsequent verification of this process; since we have not done this before, I’m not sure about it.
We have this same problem; we’re very confused and would appreciate it if experts could provide an explanation.
