Description
Technical field
The present invention relates to steel construction indirect cool tower construction fields, are especially a kind of construction party of steel construction indirect cool tower cone segments
Method.
Background technology
Certain power plant creates the indirect cool tower of two steel construction types, it includes lower part cone segments, upper cylinder, reinforcing ring,
Broadening platform, upper tower cat ladder, peripheral protective aluminium sheet etc..The high 169.01m of head tower, the base diameter of lower part cone segments is 129.44m, height
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.
Since the cone segments of above-mentioned steel construction indirect cool tower are there are angle of inclination, and heavier-weight, using conventional construction method
Its installation requirement can not be met, therefore, it is necessary to design a set of practicable arrangement and method for construction, to realize its installation.
The content of the invention
The technical problem to be solved by the present invention is to provide cold between a kind of construction efficiency height, the reliable steel construction of installation positioning
The construction method of tower cone segments carries out drawing of rising with chain block and mobile anchor point to the line that rises, to complete the centering of tripod,
And then realize the installation of cone segments.
The technical solution of the present invention is to provide a kind of construction method of steel construction indirect cool tower cone segments, including as follows
Step：
1) tripod is made, which is enclosed and made by a steel structure beam and two steel construction cant beams；
2) quality examination is carried out to several tripods to complete, carries it to steel construction indirect cool tower after qualified and pacify in advance
Holding position；
3) tripod is stood upside down and set；
4) line that rises is installed in crossbeam both sides, and mobile anchor point is installed on corresponding ground；
5) it is connected by the chain block line bottom that will rise with mobile anchor point；
6) chain block is pulled, adjusts the angle of inclination of tripod；
7) axis and the angle of inclination of tripod are observed by the total powerstation, the plumb aligner that set up in advance；
8) after axis and angle of inclination meet design and code requirement, tripod is securely installed by spot welding；
9) step 3)~8 are repeated), by the circumference installation by drawing of remaining tripod of this layer；
10) step 3)~9 are repeated), the tripod in the remaining number of plies is installed, is finally completed applying for entire cone segments
Work.
After more than structure, compared with prior art, the construction method of steel construction indirect cool tower cone segments of the present invention has
Advantages below：The present invention first installs single tripod, and then the line that rises is carried out by chain block and mobile anchor point
Rise drawing, to complete its centering, then remaining tripod is installed one by one again, the construction for being finally completed entire cone segments is made
Industry；The present invention is this higher to the modularization installation efficiency of cone segments, and it is reliable to install positioning.
Specific embodiment
The construction method of steel construction indirect cool tower cone segments of the present invention is made With reference to embodiment further detailed
Explanation：
In this embodiment, the construction method of steel construction indirect cool tower cone segments of the present invention, includes the following steps：
1) tripod is made, which is enclosed and made by a steel structure beam and two steel construction cant beams；
2) quality examination is carried out to several tripods to complete, carries it to steel construction indirect cool tower after qualified and pacify in advance
Holding position；
3) tripod is stood upside down by crane and set；
4) line that rises is installed in crossbeam both sides, and mobile anchor point is installed on corresponding ground；
5) it is connected by the chain block line bottom that will rise with mobile anchor point；
6) chain block is pulled, adjusts the angle of inclination of tripod；
7) axis and the angle of inclination of tripod are observed by the total powerstation, the plumb aligner that set up in advance；
8) after axis and angle of inclination meet design and code requirement, tripod is securely installed by spot welding；
9) step 3)~8 are repeated), by the circumference installation by drawing of remaining tripod of this layer；
10) step 3)~9 are repeated), the tripod in the remaining number of plies is installed, is finally completed applying for entire cone segments
Work.
The present invention first installs single tripod, is then risen by chain block and mobile anchor point to the line that rises
It draws, to complete its centering, then remaining tripod is installed one by one again, is finally completed the construction operation of entire cone segments；
The present invention is this higher to the modularization installation efficiency of cone segments, and it is reliable to install positioning.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to the technical side of the present invention
The various modifications and improvement that case is made, should all fall within the scope of protection of the present invention.
