She You not flange；
Step 2: pylon burst both sides set temporary ladder respectively, and in the upper and lower part of pylon burst both sides steel pipe column point
Falsework is not set；
Step 3: making Hough operating platform, Hough operating platform includes Hough bottom plate, fence, strengthens rib and Hough fastening
Circle, fence are vertical at Hough bottom plate outer ring, and Hough bottom plate center is provided with through hole, and Hough tight loop leads to located at Hough bottom plate center
Hole, strengthen rib and be located between Hough tight loop and Hough bottom plate outer ring；
Step 4: Hough operating platform is arranged on pylon burst both sides steel pipe column by fastening clip and is fixed on steel pipe column
On, Hough operating platform is located at cat ladder top；
Step 5: pylon burst is lifted to tower foundation using crane；
Step 6: assembled upper strata pylon burst and Hough operating platform, cat ladder connect upper strata pylon to repeat step one to four successively
Hough operating platform between burst and lower floor's pylon burst；
Step 7: upper strata pylon burst is lifted on by lower floor's pylon burst top using crane and is directed at steel pipe column, operating personnel
The docking construction operation of interlayer pylon burst flange is carried out on Hough operating platform, completes flange node installation；
Step 8: remove Hough operating platform, the assembly for next pylon burst using crane after flange joint installation
Installed with flange joint, so as to complete the construction that chimney reinforces pylon high-altitude installation node.
Further, when the Hough tight loop of Hough operating platform divides two halves banding pylon burst both sides steel pipe column, in Hough
Rubber washer is encased inside between tight loop and steel pipe column.
Pylon high-altitude installation node security construction method is reinforced due to chimney of the present invention and employs above-mentioned technical proposal, i.e., first will
Pylon steel structure member is assembled into pylon burst on the special stand of ground, and the steel pipe column both ends of pylon burst are provided with flange；
Temporary ladder and Hough operating platform are set on pylon burst；The two halves tight loop of Hough operating platform bottom plate wales pylon burst
Steel pipe column and fixation, Hough operating platform are located at cat ladder top；Pylon burst is lifted on tower foundation using crane；Then
With same method assembly upper strata pylon burst, upper strata pylon burst is lifted to lower floor's pylon burst using crane, is directed at steel
Tubing string, operating personnel carry out the docking construction operation of interlayer pylon burst flange on Hough operating platform, complete flange joint
Installation；Hough operating platform is removed using crane, assembly and flange joint installation for upper strata pylon burst.This method overcomes
The defects of conventional tower high-altitude installation node construction, the security of work high above the ground is effectively improved, reduce construction cost, improve
Efficiency of construction and the quality of pylon installation.
Brief description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is that chimney reinforces pylon burst scheme of installation；
Fig. 2 is that chimney of the present invention reinforces pylon high-altitude installation node security construction method schematic diagram；
Fig. 3 is the structural representation of operating platform in this method.
Embodiment
As shown in Figures 2 and 3, chimney of the present invention reinforces pylon high-altitude installation node security construction method to be included such as embodiment
Lower step：
Step 1: use steel pipe column 11, cross bar 12 and the assembled pylon burst 1 of support bar 13, the both sides steel pipe of pylon burst 1 on ground
The both ends of post 11 are respectively equipped with flange 14；
Step 2: the both sides of pylon burst 1 set temporary ladder 6 respectively, and on the top of the both sides steel pipe column 11 of pylon burst 1 with
Portion sets falsework 7 respectively；
Step 3: making Hough operating platform 8, Hough operating platform 8 includes Hough bottom plate 81, fence 82, strengthens the and of rib 83
Hough tight loop 84, fence 82 are vertical at the outer ring of Hough bottom plate 81, and the center of Hough bottom plate 81 is provided with through hole 85, Hough tight loop
84 are located at the central through hole 85 of Hough bottom plate 81, strengthen rib 83 and are located between Hough tight loop 84 and the outer ring of Hough bottom plate 81；
Step 4: Hough operating platform 8 is arranged on the both sides steel pipe column 11 of pylon burst 1 by fastening clip 87 and is fixed on
On steel pipe column 11, Hough operating platform 8 is located at the top of cat ladder 6；
Step 5: pylon burst 1 is lifted to tower foundation using crane；
Step 6: assembled upper strata pylon burst and Hough operating platform, cat ladder connect upper strata pylon to repeat step one to four successively
Hough operating platform between burst and lower floor's pylon burst；
Step 7: upper strata pylon burst is lifted on by lower floor's pylon burst top using crane and is directed at steel pipe column 11, operator
