Erection size:a vertical rod of the horizontal distance 1.2m,a vertical rod longitudinal distance 1.5m,size bar step distance of 1.8 m;
The inner frame distance from the wall length 0.15m;
A large bar on lap in a small bar,the bar number 1;
The steel pipe type:48 dia x 3.5

1.1 erection scheme and procedure
Landing scaffold erection sequence is as follows ( project only to see the 7 layer below the scaffolding and utility )
（1）The ground tamping,pole spacing according to the placement of prefabricated concrete cushion block.
（2）The erection procedures :placed a sweeping rod,by a vertical pole and a sweeping rod fastening,a sweeping rod small lateral pole and pole and a sweeping rod fastening to install first step large bar and rod fastening install first step,second step rail mounted a large bar install the third rail with the temporary braces ( the upper and the first major rail fastening,installing wall connecting rod after the demolition ),installed in third,four large bar and small bar,rod,connecting rod connecting wall with a scissors to spread sheet,rolling scaffold guardrail plate block feet,and set up safety net protection.
（3）The longitudinal ends along the scaffold and scaffolding outside corner,in every 9 M with inclined rod into scissors,top-down sequential setting,slant rod and ground into 45-60 degree angle,scissors pipe joint application of lap,lap length of not less than 40CM.
（4）The scaffolding outside since second steps,each step of 1.2M high protective railing and 30CM high block feet.
（5）The erection with a rod with correction of the vertical and horizontal deviation,while moderate tightening fastening,connecting rod fastener openings shall be toward the shelf,medial,bolt face,preventing entry of rain water.
（6）As the rod intersect protruding end is greater than 100MM,preventing rod slip.
（7）Scissors,erected to a slant buckle on the vertical rod,the other end button on a small rail extension,oblique rod fastener and the upright rod distance not greater than 200MM.
