Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further detailed explanation.
As shown in figure 1, providing one to need to implement the building body of improvement project, then this improvement project to be performed is built
Build main body and carry out preliminary structure transformation.As shown in Fig. 2 when carrying out preliminary structure transformation, first removing and/or increase building body
Horizontal structure 1, make preliminary structure transform each layer horizontal structure 1 of completing and be matched with each layer steel construction to be lifted；Then exist
Setting position is provided for connecting the embedded part 11 of steel construction.In order to prevent building body in Steel Structure Installation work progress from will bear
Larger pressure and there is accident, a diagonal brace 3 is thus set up on the bottom cushion cap 2 of building body, for building body and applying
The steel construction that work is installed is supported.Additionally, the both sides of this building body are provided with scaffold 4, workman is facilitated to carry out steel construction
The construction installed.
After the completion of the preliminary structure rebuilding construction of the building body of this improvement project to be performed, as shown in figure 3, preliminary at this
Building body top after the completion of structure of modification lifts a truss 6 by crane 5 grade suspender, installs and be related between this truss 6
Rod member (not shown), this truss 6 is fixed by this contact rod member temporarily, and prevents truss 6 from toppling over.
After the completion of truss 6 lifting, using this truss 6, lift each layer steel construction from top to bottom successively, and complete each layer steel knot
Connection between structure, and this steel construction by cantilever steel girder and contact girder steel form.First at next layer of horizontal structure 1 of truss 6
Lifting ground floor steel construction, as shown in figure 4, a cantilever steel girder 7 is transported next layer of horizontal structure 1 with truss 6 by crane 5
Put corresponding position, and cantilever steel girder 7 is carried out spot welding with embedded part 11 and fix temporarily；Plural number is installed between truss 6 and cantilever steel girder 7
Individual lifting device 8 such as electric hoist, makes cantilever steel girder 7 hang upside down on truss 6 by lifting device 8, now by crane 5 and overhang steel
Beam 7 separates.Then contact girder steel (not shown) between cantilever steel girder 7 is installed, by lifting device 8 to cantilever steel girder 7
It is adjusted with the absolute altitude of contact girder steel, after the completion of this absolute altitude is adjusted, cantilever steel girder 7 and embedded part 11 are carried out weld all around and fixes.
After the completion of cantilever steel girder 7 lifting, as shown in figure 5, a plurality of zips 9 being transported by truss 6 by crane 5 and encorbelmenting
Predetermined altitude between girder steel 7, and zip 9 is adjusted by lifting device 8, so that zip 9 is located between truss 6 and cantilever steel girder 7
Vertical position.Then zip 9 is fixed, cantilever steel girder 7 and truss 6 are connected by zip 9, zip 9 is first pacified when fixing
Load onto portion's zip bolt, then by instruments such as crowbars, bottom zip bolt is fixed, then adjust the elasticity of zip, inspection is drawn
Connection at lock node, thus completes the installation of zip 9, and then completes the projecting installation of ground floor steel construction.
Then lift second layer steel construction at next layer of horizontal structure 1 of the ground floor steel construction of above-mentioned installation.
As shown in fig. 6, crane 5 second layer cantilever steel girder 10 is transported corresponding to next layer of horizontal structure 1 position of cantilever steel girder 7
Locate, and second layer cantilever steel girder 10 carried out spot welding with embedded part 11 to fix temporarily；Encorbelment in ground floor cantilever steel girder 7 and the second layer
A plurality of lifting devices 8 are installed between girder steel 10, so that second layer cantilever steel girder 10 is hung upside down by lifting device 8 and encorbelment in ground floor
On girder steel 7, now crane 5 and second layer cantilever steel girder 10 are separated.Then contact between second layer cantilever steel girder 10 is installed
Girder steel (not shown), is adjusted to the absolute altitude of second layer cantilever steel girder 10 and contact girder steel by lifting device 8, this mark
After the completion of top adjustment, second layer cantilever steel girder 10 and embedded part 11 are carried out weld all around and fixes.Then, as shown in fig. 7, passing through crane 5
A plurality of zips 12 are transported the predetermined altitude between ground floor cantilever steel girder 7 and second layer cantilever steel girder 10, and by carrying
Rise device 8 and adjust zip 12, make the vertical position that zip 12 is located between ground floor cantilever steel girder 7 and second layer cantilever steel girder 10
Put, and ground floor cantilever steel girder 7 and second layer cantilever steel girder 10 are connected by this zip 12.Then zip 12 is fixed,
When fixing, top zip bolt is first installed, then by instruments such as crowbars, bottom zip bolt is fixed, then adjust the pine of zip
Tightness, checks the connection at zip node, thus completes the installation of zip 12, and then complete the projecting peace of second layer steel construction
Dress.
That repeats above-mentioned second layer steel construction is flip-chip mounted step, and thus to lower floor, each steel construction is flip-chip mounted, directly
