I'm sorry I've been incommunicado this week...sometimes life gets in the way of hardware. When I agreed to lend a hand to my sister-in-law during the birth of my niece, I had no idea it would take 4 days! The good news is that my niece has arrived, and I was able to spend 4 days wandering the hospital halls looking at the hardware.
I find this cool in a freaky sort of way.
After my request for readers to send me photos of hardware applications seen on their summer vacations, I received some photos of the entrance doors to the Notre Dame des Victoires Church in Quebec City, Canada. The church was erected in 1688, and is Quebec's oldest stone church.
Yesterday I spent a few hours auditing a class on the Schlage AD-Series Electronic Locks. If you haven't seen this lock yet, you should go to the website and take a look. The whole idea behind it is that it's adaptable. You can change the type of credential reader (keypad, mag-stripe, proximity/Smart Card/Multi-Tech reader) , the function (classroom/storeroom, office, apartment, privacy), or even the level of access control (offline, networked, wireless), and the changes can be made without taking the lock off the door. So you install a stand-alone keypad lock today...tomorrow you can change it to a networked wireless lock with a Smart Card reader, and only the credential reader and inside escutchen need to be replaced. The rest of the change is accomplished with free firmware.
Here's another door from the Shalin Liu Performance Center in Rockport, Massachusetts. It's actually a curved door from the existing building attached to a new door. Because of the thickness of the two doors, wide throw hinges were used. Wide throw hinges are typically used when more clearance is required behind the door when open 180 degrees, not to be confused with swing clear hinges, which move the door out of the opening when open to 90 degrees (see below for comparison).
Last night's CSI meeting was a tour of the recently-completed Shalin Liu Performance Center in Rockport, Massachusetts. It was kind of a hike especially with the threat of traffic problems, but I thought I might be able to get some good door pictures.
I posted a while back about the proposed 8th edition of 780 CMR, the Massachusetts State Building Code. The link that I had provided to the proposed code stopped working, but the information is now available online, including a read-only link to the 2009 IBC, the proposed Massachusetts addendums, and the comments and proposals from the February public hearing.
I haven't thought much about these since I was in DHI school (a really long time ago), but today I saw two types of paumelle hinges along with some olive knuckle hinges in the same facility. Beautiful hinges, but a very tough door and frame prep.
I swear, this blog is not going to become a collection of photos that can be found elsewhere on the web, but since two people sent me this photo today and it's pretty horrible, I just have to post it. It's another one from thereIfixedit.com, which is a really funny collection of weird stuff that people do to try to fix things.
I'm off to Carmel this week so it's going to be a busy one. I don't know if I'll get to the next smoke door post but I'll post some more application photos to tide you over. Here's another gravity closer with a bonus padlock on a temperature rise egress door. And before someone comments that these don't need to be temp rise doors, this opening is in Israel so I'm not sure which code was in use when they were installed.
I think I'm onto something...asking everyone to send their vacation photos of oddball hardware applications has already netted me several, including this photo of a gravity closer from Quebec City. The cable goes from the face of the door, through the pulley that the brown outfit is hanging on, then through another pulley and attaches to a weight that the green outfit is hanging on. Complicated, but pretty inexpensive as long as you don't need door control. ;-)
Last week I said that as new countries came to visit this site, I'd post a door photo from that country. Sounds like fun, right? Well, it's not as easy as it looks from where you're sitting.
After that last post I think we all need a break. Here's a "fix" from thereIfixedit.com:
According to the International Building Code (IBC), every required exit stairway that extends more than 75 feet ABOVE the lowest level of fire department vehicle access (high rise buildings), and every required exit stairway that serves floor levels more than 30 feet BELOW the level of exit discharge must comply with the referenced sections on smokeproof exit enclosures. (IBC 2009 - 403.5.4 & 405.7.2, IBC 2003 & 2006 - 403.13 & 405.8.2)
