Description
Technical field
the invention belongs to steel stack technical field of construction, especially relate to a kind of inversion construction method of steel chimney cylinder.
Background technology
at present in industrial construction, the steel stack of more than 90m gets more and more, and the steel stack of existing more than 200 meters.Steel stack for more than 90m adopts traditional construction method of installation to be very difficult, its mounting steel chimney be accurate at the bottom of bit rate, the high and construction quality of construction cycle long construction cost is difficult to ensure.As certain sintering plant four post steel tower formula bitubular body assembly type 200m steel stack, chimney structure gross weight is 2500t, and installation code requires high, and the maximum TC-2000 type mobile crane in job site also can only be lifted into 115m.
Summary of the invention
the present invention is directed to the technical problem existed in existing steel chimney cylinder installation, a kind of inversion construction method of steel chimney cylinder is provided.
the inversion construction method particular content of a kind of steel chimney cylinder provided by the present invention is as follows:
(1) by by the arranged outside of the steel chimney cylinder 1 of jacking annular joist 2, described annular joist 2 is equipped with the jack of short stroke, described annular joist 2 is to described steel chimney cylinder 1 clamping and supporting role, and described annular joist 2 supports whole load of described steel chimney cylinder 1.
(2) arrange hinged reinforcing device 4 at the inwall of described steel chimney cylinder 1, described reinforcing device 4 is expansion under jack promotes, and makes described steel chimney cylinder 1 keep positive circle.
(3) at the arranged outside jacking post 5 of described ring-type joist 2, main jack is equipped with on the top of described jacking post 5, between described jacking post 5 and steel chimney cylinder 1, pulling apparatus 3 is set, described pulling apparatus 3 is connected with described ring-type joist 2, the impulse stroke location 900mm of described main jack, make described ring-type joist 2 together with cylindrical shell 1 jacking six times, complete the jacking of a cylindrical shell.
(4) after steel chimney cylinder 1 is by top to △ h height, locked by the jam nut 7 being arranged on described jacking post 5 top, now described cylindrical shell 1 rests on △ h height safely.
(5) another section of steel chimney cylinder is placed on transport jacking trolley 6, be pushed into the center of described cylindrical shell 1, six jack are had at described transport jacking trolley 6, described transport jacking trolley (6) and another section of steel chimney cylinder on it are carried out jacking, described another section of steel chimney cylinder centering butt welding mouth is welded with described steel chimney cylinder (1).
(6) described ring-type joist 2 is unclamped with the whole off-load of jack of reinforcing device 4, depart from described steel chimney cylinder 1, described main jack drives described ring-type joist 2 with 900mm backhaul six times, then make whole device get back to original position and carry out lifting operation again, such cycle jacking, until described steel chimney cylinder 1 is thus lifted to desired height.
the inventive method is by cylindrical shell upside-down method of hull-section construction, is exactly from bottom to up by the method got in cylindrical shell top, in place by the initial segment of crane lifting cylindrical shell, and all the other height component of cylindrical shell are divided into n section, and selected every section of height is 5400mm.After cylindrical shell jack-up 5400mm height, new one section of cylindrical shell 5400mm is pushed, after jack-up, carries out butt welding.Install the tower crane for building of a 80t.m in cylindrical shell upper end, this tower crane rises with stack shell, and after the some height of stack shell jacking, stop jacking, tower crane can install the component of epimere pylon and platform, and pylon is installed to certain altitude, and it is high that cylindrical shell can continue again jacking 5400mm.Repeat so alternately, cylindrical shell, pylon, elevator all can all fulfil assignment, until described steel chimney cylinder is thus lifted to the desired height of 200m.
the inventive method is safe and reliable, it is high and can reduce construction cost to save duration, construction quality and efficiency.

Detailed description of the invention
now in conjunction with the accompanying drawings and embodiments the construction method of a kind of steel chimney cylinder upside-down mounting that the present invention proposes is described further.
certain sintering plant four post steel tower formula double shell assembly type 200m steel stack, chimney structure gross weight is 2500t, and installation code requires high.Use the inventive method construction can safely, on schedule, the construction task of 200m steel stack of having guaranteed the quality, it is hundreds thousand of to save large-scale crane lifting machine-team expense, reduces construction cost and reaches more than 30 ten thousand yuan.
the inversion construction method of this 200m steel chimney cylinder is specific as follows:
(1) by by the arranged outside of the 200m steel chimney cylinder of jacking annular joist 2, annular joist 2 is equipped with the jack of 12 short strokes 20 tons, it rises cylindrical shell and clamps and supporting role, supports by whole load of the cylindrical shell of jacking.
(2) arrange hinged reinforcing device 4 at cylinder inboard wall, this reinforcing device 4 is expansion under 200 tons of jack promote, and makes cylindrical shell keep positive circular.
(3) at the arranged outside jacking post 5 of ring-type joist 2, main jack is equipped with at the top of jacking post 5, arranges pulling apparatus 3 between jacking post 5 and steel chimney cylinder 1, and pulling apparatus 3 is connected with ring-type joist 2.The impulse stroke location 900mm of main jack, can make ring-type joist 2 together with cylindrical shell 1 jacking six times, complete the jacking task of a cylindrical shell.
(4) after cylindrical shell is pushed up to △ h height, locked by jam nut 7, now cylindrical shell rests on △ h height safely.
(5) another section of cylindrical shell is placed on transport jacking trolley 6, be pushed into body centre position, 6 jack are had at transport jacking trolley 6, transport jacking trolley 6 and another section of steel chimney cylinder on it are carried out jacking, makes described another section of steel chimney cylinder centering butt welding mouth carry out welding centering butt welding mouth with described steel chimney cylinder 1 and weld.
(6) the jack whole off-load of ring-type joist 2 with reinforcing device 4 is unclamped, depart from cylindrical shell, main jack can drive ring-type joist 2 with 900mm backhaul six times, whole device is made to get back to original position, carry out lifting operation again, such cycle jacking, until steel chimney cylinder is thus lifted to required 200m height.
