Detailed description of the invention
Below in conjunction with accompanying drawing, the suspension type steel structure lighting skylight construction method of the present invention is described in detail.
The suspension type steel structure lighting skylight construction method of the present invention comprises the following steps:
1) assembled roof light steel construction. As shown in Figures 2 and 3, roof light steel construction is assembled at the upper surface of layer 5 floor in the present embodiment. Roof light steel construction includes steel structure net rack 15 and is supported in the prestressed girder 14 of steel structure net rack 15 lower surface. Prestressed girder 14 can strengthen steel structure net rack 15, so that roof light steel construction can have bigger span.
In the present embodiment, the area of roof light steel construction is relatively big, therefore roof light steel construction is divided into multiple region, carries out assembly. The concrete assembled process of roof light steel construction comprises the following steps:
As Fig. 1 to and Fig. 4 shown in, the height of first area 10 is higher, and the lower section of first area 10 does not have the supporting constructions such as floor, therefore uses the roof light steel construction 11 of the mode assembly first area 10 of accumulation slippage in the method. The assembled process of first area 10 specifically includes: first setting up two sliding rails 12 parallel to each other, the end of sliding rail 12 is concordant with layer 5 floor. Setting up the roof light steel construction unit 13 of bar shaped subsequently on layer 5 floor, each roof light steel construction unit 13 includes many prestressed girders 14 and the steel structure net rack 15 being connected between prestressed girder in the present embodiment; The two ends of the roof light steel construction unit 13 of bar shaped are set up to sliding rail 12 after completing by roof light steel construction unit 13 assembly; Use thrustor by roof light steel construction unit 13 pushing tow to precalculated position subsequently. Steps be repeated alternatively until roof light steel construction 11 assembly of first area to complete. Fig. 3 and Fig. 4 is the schematic diagram after roof light steel construction 11 assembly of first area 10 completes. The roof light steel construction 11 of first area 10 is as shown in Figure 3. The mode adopting accumulation slippage assembled can be avoided using large-scale hanging device, it is also possible to avoids the problem that the mode that high-altitude dissipates spelling needs to set up supporting construction.
As it is shown in figure 5, use rod member scene dissipates the roof light steel construction 21 of the mode assembly second area 20 of spelling. Use rod member scene to dissipate in spelling process, first set up moulding bed at the upper surface of second area 20, layer 5 floor, set up roof light steel construction 21 at the top of moulding bed subsequently. Fig. 4 is the schematic diagram after roof light steel construction 21 assembly of second area 20 completes.
In step 1 and step 2, the roof light steel construction of first area 10 and second area 20 include multiple prestressed girder 14 parallel to each other and be arranged at above prestressed girder 14 steel structure net rack 15. The roof light steel construction having set up rear first area 10 and second area 20 is positioned at identical height.
As shown in Figure 6, it is transitional region 30 between first area 10 and second area 20, in the assembled attachment structure 31 connecting first area 10 and second area 20 of transitional region 30. In the present embodiment, attachment structure is steel structure net rack.
As shown in Figure 7, threeth region 40 adjacent with first area 10 is due to the stop of xoncrete structure, slipping and assembling cannot be passed through, therefore at the skylight steel construction 41 in assembly the 3rd region 40, edge of first area 10 after skylight steel construction 11 assembly of first area 10 completes together with the skylight steel construction 11 of first area 10.
2) prestressed cable 141 of prestressed girder 14 is carried out first time prestressed stretch-draw after roof light steel structure assembling completes. In the process of first time prestressed stretch-draw, prestressed cable 141 is stretched to percent the 90 of design load, so makes roof light steel construction in follow-up hoisting process can have enough intensity.
3) by roof light steel construction integral hoisting to predetermined altitude, and by its suspended fixing in supporting construction. As shown in Fig. 7, Fig. 8 and Figure 10, by roof light steel construction 11,21,31 and 41 integral hoisting in the first to the 3rd region to predetermined altitude, and it is installed on supporting construction. As shown in Figure 8, in the present embodiment, the supporting construction of roof light steel construction side is be suspended to the suspension rod 43 below structural beams 42, and the supporting construction of opposite side is vertical steel structure 44.
4) after installation, the prestressed cable 141 of whole prestressed girders 14 is stretched to design load. After prestressed cable 141 is stretched to design load, the intensity of roof light steel construction reaches maximum. As it is shown in figure 9, after prestressed cable 141 stretch-draw completes, the assembled roof light steel construction 51 in the 4th region 50. At roof light steel structure surface, cladding glass 52 is installed.
Technical scheme has following useful technique effect: adopt the mode sub-module assembly steel structure net rack of horizontal sliding pushing tow, it is possible to avoiding that steel structure net rack weight is excessive cannot the problem of integral hoisting. Adopt modular assembling method that the mode of streamline can also be adopted to arrange working procedure, thus saving the engineering time. At the assembled each strip element of layer 5 slab surfaces, hence it is evident that what decrease support system and operating platform sets up quantities.
Above in association with accompanying drawing embodiment, the present invention being described in detail, the present invention can be made many variations example by those skilled in the art according to the above description. Thus, some details in embodiment should not constitute limitation of the invention, the present invention by the scope that defines using appended claims as protection scope of the present invention.
