Abstract
The invention discloses a method for constructing a multichannel interval load-carrying mega truss door structure. According to the method, ground assembly is adopted for a first channel interval load-carrying mega truss and a last channel interval load-carrying mega truss, then the whole synchronous hoisting installation is conducted, the bottom-to-top high-altitude loose assembly is adopted for a plurality of channels of middle interval load-carrying mega trusses, after each channel middle mega truss is installed, unloading of a steel truss is finished immediately, and then corresponding frame structures on upper portions are installed to carry loads independently. By the aid of the method, separate loading of all channels of mega trusses can be achieved, and the installation method of ground assembly and overall hoisting is adopted by the first channel load-carrying truss and the last channel load-carrying truss, so that the difficulty of assembly welding of mega trusses can be reduced, assembly welding and other structure construction can be conducted synchronously, and the schedule can be saved.
Description
Technical field
The invention belongs to the earthwork engineering technical field of construction, relate to the huge truss construction method of a kind of load, particularly the huge truss door type structure of the interval load of a kind of multiple tracks job practices.
Background technology
At present for the super highrise building that has adopted the multiple tracks transfer truss, its design concept all is that the multiple tracks truss is jointly stressed, therefore job practices is constructing structure progressively from bottom to top substantially, and the truss high altitude bulk forms, integral body of each road truss and the formation of its upper and lower structure.But for the huge truss door type structure of the interval load of multiple tracks, its design concept is that the huge truss in each road is stressed separately, as still adopting traditional job practices, is difficult to realize design idea.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can realize the separately stressed huge truss door type structure of the interval load of multiple tracks job practices of interval each the huge truss of multiple tracks, the defects that exists to overcome prior art.
The technical scheme of technical solution problem of the present invention is as follows:
The huge truss door type structure of the interval load of a kind of multiple tracks job practices is characterized in that, adopts installation on ground, then Integral synchronous erection ﹠ lift for first road and the huge truss of the interval load of extreme trace; Adopt the method for high altitude bulk from bottom to top for the huge truss of the interval load in some roads, centre, after the huge truss installation, finish immediately the unloading of steel truss in the middle of the per pass, then top respective frame structure is installed, make it begin independent stressed.
By above disclosed technical scheme as can be known, the huge truss door type structure of the interval load of multiple tracks of the present invention job practices, can realize the stressed separately of each huge truss in road, and because first and last twice load-bearing truss adopts the mounting means of the whole assembly in ground, Integral lifting, reduced the difficulty of huge truss assembly unit welding, and can carry out synchronously with other structure constructions, be conducive to save the duration.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Shown in Fig. 1 ~ 7, the huge truss door type structure of the interval load of multiple tracks job practices adopts installation on ground, then Integral synchronous erection ﹠ lift for first road and the huge truss of the interval load of extreme trace; Adopt the method for high altitude bulk from bottom to top for the huge truss of the interval load in some roads, centre, after the huge truss installation, finish immediately the unloading of steel truss in the middle of the per pass, then top respective frame structure is installed, make it begin independent stressed.
Embodiment such as certain engineering adopt huge trussed construction, designed the huge load steel truss in five roads, wherein the first steel truss is positioned at 6 ~ 8 layers, second steel truss and is positioned at 19 ~ 20 layers, the 3rd road steel truss and is positioned at 30 ~ 31 layers, the 3rd road steel truss and is positioned at 39 ~ 40 layers, and the 5th road steel truss is positioned at M51 ~ RF layer.First to fourth road steel truss (from bottom to top) is independently born about about the 10 layers steel frame in top.The steel truss span is 49.2m, and the 5th road steel truss is roof truss, independently bears the two-layer suspension steel work of the two-layer steel frame in top and bottom layer.The huge truss of first has reached 1500t.
Shown in Fig. 1 ~ 7, adopt job practices construction of the present invention, specifically comprise the steps:
(1), door type structure both sides strengthening concrete cylindrical shell keeps synchronous construction, the huge truss of the interval load of first is at the ground integral assembling;
(2), the huge truss of the interval load of first after the ground integral assembling is finished, Integral synchronous promotes put in place (6 ~ 8 layers) and is connected with both sides strengthening concrete cylindrical shell;
(3), 9 ~ 18 layers of steel framed structure on the interval load mega-frame of first top are installed, the load of this part steel framework rack-layer is independently born by the huge truss of the interval load of first;
(4), the superiors' 18 layers of steel framed structure layer steel frame cylinder of utilizing the interval load mega-frame of first load is as support system, carries out the huge truss high altitude bulk of the interval load of second; The huge truss of the interval load of second is installed after welding finishes, throw off its with 18 layers of steel frame cylinder between interim the connection, realize the stressed independence of the huge truss of second interval load;
(5), 21 ~ 29 layers of steel framed structure are installed, the load of this part steel framework rack-layer is independently born by the huge truss of the interval load of second.
(6), the steel frame floor of the interval huge truss of load in repeating step (4), (5) high altitude bulk the 3rd road and the 4th road and each truss top, road.
(7), the huge truss of the interval load of integral assembling extreme trace on upper floor 49 floor faces.After assembly unit was finished, Integral synchronous promoted put in place M51 ~ RF layer and installation.
By adopting job practices of the present invention, the huge truss installation on ground in the first and the 5th road, Integral synchronous erection ﹠ lift; The second to the 4th huge truss adopts the mounting means of high altitude bulk.After the installation of per pass steel truss, namely to throw off with substructure, the truss top needs to continue construction upper steel frame construction floor, realizes the region stress characteristic of per pass load-bearing truss.
