ERECTING PREPARATION 3. ERECTING PREPARATION PRINCIPLES (6): 1) TRANSPORATION OF STRUCTURE ELEMENTS 1. Strenth of element must obtain that for moving. For concrete one, strength must having at least 70% of R28. 2. Element situation during moving should be similar to that at working condition (just to avoid stresses occurred different as disigned) WORKING SITUATION OF ELEMENTS PRINCIPLES (6): 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS 3. Bending elements must be chocked by using wooden pieces following designed positions (hook position) PRINCIPLES (6): 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS 4. When members laid on each other, supported (chocked) points should be on a vertical direction 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS 5. When a long member is laid on 2 rail carriages, it should be supported on 2 different points, so the carriages can be rotated during transportation. PRINCIPLES (6): Support point – rotation point 3. ERECTING PREPARATION 1) TRANSPORATION OF STRUCTURE ELEMENTS 6. Length of structure member should be fit on truck, so it could be passed at corner of streets or roads. PRINCIPLES (6): 3.
