.described feed-through hydraulic jack, for the Special jack of the presstressed reinforcing steels such as stretch-draw steel hinge line, needs and stretching oil pump is used in conjunction with, and stretch-draw and the power that returns back to top provide by the hydraulic oil of stretching oil pump.
In the Integral lifting installation of the large area rack on the roof of Digital Television TV mansion, Tianjin studio centre attached building, and complete safely the Integral lifting installation engineering of large area rack.
The large area rack on the roof of Digital Television TV mansion, described Tianjin studio centre attached building, for adopting the dual-layer welding ball node rack of the space structures being formed by wind up layer, lower edge layer and web member layer, rack west and east span 44.2m, north and south span 33.2m, high 3.484 ㎡ of rack, the rack gross area 1468 ㎡, heavy 130t, net rack support height 18m.The top-bottom chord of steel structure net rack is the pipe of φ 219 * 20 to the maximum, and web member is the pipe of φ 114 * 4 to the maximum, is welded spherical node rack, and what connect ball maximum is the hollow ball of D600 * 30, and hollow ball total quantity is 413.8 degree are provided fortification against earthquakes.The periphery narrow space that steel structure net rack is installed, Elements of Space Grid Truss surrounding has end bay structure.
In the integral hoisting construction engineering of the Large Area Steel rack of the building that has end bay structure for roof and the surrounding thereof of Digital Television TV mansion, above-mentioned Tianjin studio centre attached building, how to select economy, safe and reliable a kind of lifting means that is different from prior art to implement the Integral lifting of Large Area Steel rack, becoming the problem that building industry engineers and technicians extremely pay close attention to, is also the urgently problem of R and D of construction engineering technician.
Utility model content
The purpose of this utility model, be to provide the auxiliary construction with safe and reliable, stability and workable a kind of steel structure net rack Integral lifting, it has lifting steadily, lifting difference is little, synchronism is good, and work efficiency is high, the characteristic of construction safety, and do not need to arrange the short steel column of temporary supporting, just the bearing of rack bottom surface can be risen to the fixed point of capital.
For realizing the purpose of this utility model, the technical scheme adopting is:
An auxiliary construction for steel structure net rack Integral lifting, is characterized in that: by the hanger of suspension centre on the extension bottle gouard moved by hands being welded on structural column bracket end face built-in fitting and be arranged on each periphery bearing ball of rack below, apart from the high 4m of lower edge ball place, as the auxiliary suspension centre of the lower suspension centre of hoisting grid, form.
Described hanger, its structure is 114mm * 4mm steel pipe post steel pipe post.
Described auxiliary suspension centre, its planform is the planform of the single cone in four sides
.
Advantage of the present utility model and beneficial effect
