Spend 55m, a diameter of 82m, the height 114.01m of upper cylinder.The indirect cool tower is by triangular mesh, reinforcing ring, broadening and outer
It goes along with sb. to guard him aluminium sheet to assemble, entire tower body is steel construction, and separate unit tower body steel structure weighs about 4102.2 tons, separate unit peripheral protective aluminium sheet
Weigh about 238 tons.Totally 5 layers of lower part centrum section, totally 13 layers of upper cylinder, every layer includes 36 groups of tripods, and single tripod is about
5.42 tons, wherein, have three layers reinforcing ring in Upper cylindrical body, about 166.45 tons of every layer of reinforcing ring, height respectively 90.08m,
125.16m and 160.24m.Entire tower body is sealed to form (about 42868 ㎡) by aluminium alloy contour plate.
Due to being relatively large in diameter for steel construction indirect cool tower upper cylinder, and height is high, and it is very big to install difficulty in place, without applying
Work method may be referred to, therefore, it is necessary to a set of practicable construction method be designed, to meet indirect cool tower upper cylinder section
Construction.
The content of the invention
The technical problem to be solved by the present invention is to, a kind of construction method of steel construction indirect cool tower upper cylinder is provided,
Solve the technical issues of larger diameter cylinder is difficult to install.
The technical solution of the present invention is to provide a kind of construction method of steel construction indirect cool tower upper cylinder, including
Following steps：
1) tripod is made, which is enclosed and made by a steel structure beam and two steel construction cant beams；
2) upper lock plate is installed at the both ends of crossbeam, lower locking plate, upper lock plate and lower locking plate is installed in the intersection of two cant beams
On offer through hole；
3) quality examination is carried out to several tripods to complete, is carried it after qualified to lower part cone segments institute enclosure cavity
In body；
4) tripod handstand lifting will be pre-installed to installation site using tower crane, it is ensured that the lower locking plate of its bottom is with having installed
Upper lock plate on tripod crossbeam aligns, and a back of the body thick stick is interted in the through hole of up and down jam plate, and between back of the body thick stick and hole wall
Fill in flat chock；
5) flat chock is hammered, adjusts the wrong variable between upper and lower tripod, flushes the two outer surface；
6) adjustment lifting angle, and using the verticality for the line adjustment pre-installation tripod that rises, pass through the vertical standard set up in advance
Instrument detects its verticality, it is made to meet design specification requirement；
7) by tripod fixation and welded using spot welding mode；
8) step 4)~7 are repeated), by the circumference installation by drawing of remaining tripod of this layer；
9) step 4)~8 are repeated), the tripod in the remaining number of plies is installed, is finally completed applying for entire cylinder
Work.
After more than structure, compared with prior art, the construction method of steel construction indirect cool tower upper cylinder of the present invention
It has the following advantages：The present invention first constructs to single tripod, is then lifted to pre-installed position, then to right
Intert back of the body thick stick in neat upper and lower jam plate through hole, carry out centering, welding to tripod by way of hammering flat chock, next
Remaining tripod is installed one by one again, is finally completed the construction operation of entire upper cylinder；The present invention is this to Upper cylindrical
The modularization installation of body, construction efficiency is higher, and it is reliable to install positioning.
Description of the drawings
Fig. 1 is side structure schematic view when intermediate cam frame of the present invention, jam plate, back of the body thick stick and flat chock are installed together.
Specific embodiment
The construction method of steel construction indirect cool tower upper cylinder of the present invention is made with reference to the accompanying drawings and detailed description
It is further described：
As shown in Figure 1, in this embodiment, the construction method of steel construction indirect cool tower upper cylinder of the present invention,
Include the following steps：
1) tripod is made, which is enclosed and made by a steel structure beam and two steel construction cant beams；
2) upper lock plate 12 is installed at the both ends of crossbeam, lower locking plate 15,12 He of upper lock plate is installed in the intersection of two cant beams
Through hole is offered on lower locking plate 15；
3) quality examination is carried out to several tripods to complete, is carried it after qualified to lower part cone segments institute enclosure cavity
