Saw a beaut today Independent scaff 6/7 lifts all 2m high all boarded. handrailed and rakered every other bay, but rakers came off top handrail to inside ledger and to finish it off rakers fixed with nice yellow sponge jonnys to stop people without hats on banging their pollys. Could a drawing man tell if this right
Is this proper scaffolding

I cant see why it would be rakered back like that, tbh.
It'd be too shallow to be doing anything too structural to the job...

Bracing from the top guardrail is allowed under TG20, but should be fixed in every bay.

They was probably to fat to bend down to put the swivells on

morning Guys
Bracing to the guard rail is as old as the hills the idea was to allow a barrow to pass, However ISL is correct these braces are required every frame line.

Thats right Alan.
I worked on a job in 1892 and we had to to this, to allow 'Orse n Cart' to traverse the lift. :laugh:

Done tower blocks in the 80s with 9 foot lifts and we always braced from the handrail every other standard , never seem to be any problems , it was the done thing

As you say Mate.... it was always the normal way to to do 9 and 10 foot lifts.....and never any problem, but a bit strange on a 6' 6" lift ???
No problem bracing off the top handrail to give headroom on a 6 board wide ( 1 inside) scaffold. Done hundreds like it and never had a problem. 8ft to 9ft lifts even better.
Don't forget it's the tieing patten that matters the most.

Yep that was the normal way of bracing on all the Wimpy "H" blocks I worked on with the 9ft lifts.15, 17, and 25 stories, gave easy access for the concrete gang pouring the "Wimpy no finds".Floor a week built come what may

Correct scaffy
"lean" concrete mix wimpy invented for the vertical walls looked like a load of pebbles with the cement and water "slick" to bind it together. The columns and slab were of traditional concrete

It states below for use in low rise, beleive me we used it on high rise
Wimpey No-fines concreteDescription:George Wimpey and Co. developed a system of housing using no-fines concrete and traditional construction methods. The concrete without sand has unusual properties in that it can be cast within a mesh or standard formwork and exerts less pressure while mobile than normal concrete. Its porous nature provides some insulating properties although not adequate for today’s requirements. In excess of 300,000 low-rise dwellings from the mid-1940s onwards were built in configurations ranging from bungalows, houses and low-rise blocks of flats of up to 5 storeys.
Before 1951 the external walls were commonly 12” (305mm) thick, whereas between 1951 and 1964 this reduced to 10” (250mm). After 1964 the external walls were commonly 8” (200mm) thick. As a general method, a band of reinforcement bar was incorporated in dense insitu concrete at eaves level. Support above ground floor door and window openings is provided by precast lintels with projecting reinforcement, although before 1951 only reinforcement bar was used. The load bearing internal walls were sometimes masonry or timber rather than no-fines. The no-fines sometimes formed the inner leaf of a masonry-faced cavity construction. Rendering was applied in two or more coats to the external face depending on the exposure conditions. Internally the walls were dry-lined or hard plaster. The party walls were sometimes rendered to reduce sound transmission.

Anyone who has been in the game long enough would know they used Ox's and not orse's.
This brace method is still very common today
