I had an amazing visit to Lacombe Toilet Rentals! They taught me so much about their industry, and maintenance of portable washrooms. I was able to see all the different types of portable washrooms they owned, and was able to get new leads to other companies, and technologies.
Their business mainly served special events (ex. Blues fest/ weddiings) and construction. The special events toilets were newer and once they get used and beaten to a certain point they get moved down the line into a construction portable washroom. Lacombe customizes their portable washrooms using the same side wall panels as the typical washroom, but add additional corner plates, and wooden base frame to create a greater footprint for the construction workers. This is perfered by the construction industry as construction workerse are usually of larger build.
The side wall panels are connected with rivets. ( one per 8.5")
(To be continued, I'm going to a design talk in the library)
As are the floors to the side walls. The floor is molded so that there are edges/ rims that can be riveted to the side walls. The toilet is standard and are connected to the wall at the top of the toilet. And the floor has (inset?) that allows the toilet to fit into.
Flush systems: there are pedals and there are hand cranks. It can use fresh water, grey water from the hand wash, or can use waste water, using the water from the waste tank as it's flushing water. The more waste water is used the stronger the scent become.
Sound is not currently dealt with.
Air ventilation is achieved through the toilet vent, and screens at the top of the unit.
Everything requires maintenance, the ceiling least of all. Other areas of consistent repairs includes door hinges because of the weight of the door. the spring on the door which allows the door to close on its own, requires repair. many of these parts are modular, so when one is broken it can be easily replaced.
I also learnt that the weight of the water when the portable washroom is filled is what keeps the unit in place. An empty unit weights about 300 lbs.
Wall thickness 3/8 "
floor thickness 0.5"
door thickness 2"
forklift is used during tranportation in the factory, however on site, there are no forklifts. There may be dollys.
During transport, the doors and units are held in place with a strap.
The doors have metal inserts for strength, and the edge of the door (cavity) in the side wall have a metal "horseshoe". adding rigidity.
Polyproplene - the plastic used - is surprisingly strong, it can bounce back when pressure is applied.
In terms of floor drainage, during washing, the excess water flows down throught he cracks in the edges of the wall to the floor, and at where the toilet connects to the floor. The floor is not perfectly flat.
Current systems rely on evaporation to dry. In the summer, water evaporates within 5 minutes.
I also checked out the accessible portable washrooms units on the canal. They have ample amounts of space, however I noticed it was uncomfertable to use. Why? The doors locks after a few days were broken and can not be securly closed and locked. There was garbage everywhere, and because of the winter conditions, it made the floor highly wet.
Roofs are white, because it lets light in. (Reflects light as well, so keeps it cooler)
I went to RV Canada to understand slide outs and pinion gears.
They gave me resources to look into to better understand self locking mechanisms so I have to look at Lippert Components - they're the one who manufacture RVs
I also learned about Limeter, as its electricity run, I wonder if I could apply it?
I also looked at doble acting spring hinge - so that the door can swing in both direction and still be brought back to neutral.
