T&F Staircases

Would love a little input from the NASC on this one. Why does it need design input when building for the general public but not if built for site operatives???
 
T & F Staircases

Hi Ian

The site staircase is only for light access with a live load of 0.75 kN/sq.m. so not very heavy duty.

Must admit some of the timber staircases with the quality of the timber treads and the angles are not always satisfactory.

Lot more of our scaffold contractors using the steel treads with the lugs on the end.

Public staircases can be 4.0 or 5.0 kN/sq.m. so would be heavy duty and higher risk so need a design.

I am sure most scaffolders have enough issues with designs for other items at the moment.

All the best

hi ChrisEng. the firm l woz workin for had exactly the same problem as XxIANxX. they where up against another firm for a job,nd it needed a public access staircase. so my firm got a design for one and the costings,the other firm however didn't !! they got the first phase of the job,nd put up a site stair access,but when it was handed over the contractor discovered the mistake nd the differences needed between the 2. so they ordered the other firm to put right the stairs nd then took the main contract off them,nd gave it to the firm l woz working for. they got in2 a whole heap ov trouble coz ov this stair access,nd decided cheapest wasn't always bestest !!!
 
Public Stairs

Hi

One of the better solutions for a public stair is the Layher system.

This has treads which are close to complying with the building regs for rise and going, take a live load of 6.0 kN/sq.m., have handrails frames with close uprights, and the treads are slip resistant.

Only problem is they are quite expensive to buy in the first place and only work to 1.5m landing levels.

The bolted timber stringers and treads, with plywood to the sides and slip resistant plywood, are okay though, and these could be made to suit the site conditions.

All the best

yep they sure are , used them 2 week ago to give access to a railway line in liverpool , roped them down a air vent shaft 7 lifts 8' x 21' walkway then used 2 of them stairs one for up and one for down to the track, to do it in T&F would have been a ballache as it was a friday night !!
 
coplok public access staircase is also a very good system. incorporates 1m wide alloy staircase, in lifts of 1.5m, or 2m. loadings can be up to 5kn per m2. expensive, but fast to erect.

we have4 some aluminium kwikstage staircases but they only 600 wide and a bit of a pain in the ass , i know the asp stairs like your pic for between 1.9m - 2.9m are 600 a pop to buy , id worry about them getting knicked on site or run over my a rogue forklift

Yes. Its the 10 leg one. 2.5m wide x 5.1m long. There is also a10 leg version 1.8 m wide,and 4 leg and 8 leg also 1.8m wide, not classed as public access. What makes the differences it seems is the wider staircase unit,the guardrail unit on platform and staircase,which provide a neat finish.If you already have the basic cuplok components you would just need to add the staircases and handrails, worth it if you think you could get the work for it. Sorry Red Viking cant post a pic as my computer skills are nowhere as good as yours. Cheers.
 
staircase

Another option is modular staircase components. Seperate stiles and stairtreads, hooks on and treads slide in,very fast and lighter to handle. Although made for cuplok,could easily be adapted to suit any system,including tube and fitting if your carefull with your measurements i.e. lift heights and width.

Yeah pal I tried to put a pic on but was protected , I used the cuplock towers for access to mastclimbers they alright but I prefer the 4 legs of haki , treads are heavy !!! Have you seen my album "haki compact tower "?
