Tower Crane plays an extremely important
role in the building construction, especially for high-rise building
construction, is the most important vertical transport machinery. So layout
crane design, compact, will give the construction safety, progress has brought
direct benefits, and can save secondary transport cost savings. Depending on
the layout of the building crane due to circumstances and should, vary. Outside
the building layout, tower crane foundation is not linked with the building
structure, does not destroy the integrity of the structure, the construction is
also very convenient. Single high-rise buildings, while the podium is small in
size, the crane can be arranged outside the building. But larger podium, I want
to share one or two high-rise tower cranes, for the crane operating radius can
cover the entire project, and often need to be arranged between the two
buildings crane, tower crane foundation so it must be attached to the basement
floor together.
General practice are:
1. Based on the construction front floor construction, the floor through the foundation, the foundation around the steel plate aside. The advantage of this approach is to be installed in the front floor construction crane good, which can make full use of crane transport steel, template, concrete and other materials at the time of the floor construction. But the biggest drawback is the basis for four weeks set aside a construction joint, on the floor seepage is a risk, it is also detrimental to the structural integrity; and because the floor is not designed crane loads, so the need for the local parts of the floor structure reinforcement.
2. After pouring the concrete foundation plate construction. Its advantages are: convenient construction, without leaving dowels, no floor construction joints. Disadvantages are: (1) can not use the crane transport substrate material; (2) because the thickness of the bottom plate thickness is generally not enough Taki, so the foundation concrete floor up a large portion of this need concrete chisel off large quantities; (3) The same need for structural reinforcement of the floor.
