S24, as shown in figure 12, lift the tubular truss A3 be connected with the tubular truss B4 that step 22 lifts, tubular truss A3 one end is connected with concrete embedded part A5, the tubular truss A3 other end is supported on lattice column 26 and pushes up, and draw and establish cable wind rope to facilitate truss to adjust, then the shuttle-type steel pipe column 1 that the tubular truss B4 this tubular truss A3 and step 22 lifted and step S23 lifts is connected, the lattice column 26 below the tubular truss A3 then removing the nearest installation described in step S21;
S25, repetition step S21 ~ S24, until complete the lifting of steel structure truss, as shown in figure 13, remove lattice column 26, complete construction.
This construction technology can be applicable to span greatly, three-dimensional system that highly high, overall trussed construction bearing capacity is large, under the prerequisite of smooth construction, ensure that the orderly of construction and efficiency, simultaneously, ensure that the steadiness of component in work progress, effectively solve the technical barrier in Steel Structure Installation process, ensure that construction quality, save the duration.Adopt, at fusiformis steel pipe column on-station position, lattice column 26 is installed, utilize lattice column 26 to do and support fixing Hoisting Program lattice, solve the technical problem that fusiformis batter post installation difficulty is large, and lattice column 26 can have enough to meet the need use, save the consumption of lattice column 26, thus provide cost savings.
Before described step S1, also comprise the step that arranges horizontal transport track on the flooring installing inverted triangle tubular truss or ground, the assembly of inverted triangle tubular truss is transported by described horizontal transport track, and horizontal transport orbital arrangement is on concrete column and girder.Thus be convenient to the carrying of assembly, improve efficiency of construction, save artificial.
Described inverted triangle tubular truss is arranged on flooring, and described construction sequence also comprises one is carried out scaffold reinforcing step to this flooring.This just makes the utility model to be applied to have on the top board flooring of basement.
As mentioned above, the utility model can be realized preferably.
