Various utensils and fitting-out work etc., successive projects are separately constructed.
5. there are also better sequences of construction, it is installed in roof girder 2, after roofing beam column frame has been formed, does not start temporarily
Jack does not jack temporarily, continues to install roof boarding engineering, and by whole roofworkss of design requirement and then dismounting
The temporary connecting plate 10 of column column between room room column 1 and suspension column 7, then jack is started, by complete by examination, whole room
Face engineering jacks N layer of height, other each layers such as N-1 layers, N-2 layers ... until the top N-N, all as roofworks,
Each layer wouldn't start thousand tops after the completion of beam column frame, wouldn't jack, but continue to complete this layer of floor project, various walls
Plate engineering, door and window work, stair engineering, various pipelines and the installing engineering ... of various utensils etc., after the completion of above-mentioned engineering
The temporary connecting plate 10 of column column is removed again, then starts jack, and the engineering completed is jacked to the height of this layer of layering column.This
Kind operational procedure is optimal, can be that automated construction from now on lay the foundation.
6. being installed between the surface of jack 20, upper and lower two layerings girder 3 to improve structural framing stress equalization degree
Between the both ends of wall center pillar 18 and upper lower leaf girder 3 with bolt 12 or connection is welded and fixed in wall center pillar 18, and wall center pillar 18 is arranged
Indoor finishing is not influenced among wallboard.
7. small shear wall is arranged, to reinforce building between upper lower leaf girder 3 between wall center pillar 18 and layering column 8
Stability.
