Referring to Fig. 1 and Fig. 2, vertical columns and column to be fixed are internally provided with lower channel, and people shuttle in upper and lower
To fixed convergence piece in channel, the door body into lower channel has been offered on the post jamb of vertical columns.Vertical columns with
Ladder is provided on column inner wall to be fixed as lower channel, the people on operating platform 9 pulls column to be lifted simultaneously when standing
By column to be lifted with after vertical columns are aligned, another lineup is entered inside column by column entrance 15, is climbed by ladder
It rises to vertical columns and column junction to be fixed and carries out the fixation work of convergence piece.
Optionally embodiment, referring to Fig. 1 and Fig. 2, operating platform 9 is fan ring structure, and operating platform 9 is not encircled
The region of vertical columns constitutes the lower channel of column to be fixed, the place upper side of lower channel be provided with rotation section with
Spacing is greater than two support rods of column outer diameter to be fixed.Operating platform 9 is fan ring structure, so that there is one on the outside of column
Divide and be not provided with operating platform 9, column to be fixed is avoided and mentioned in column to be fixed from promotion from operating platform 9 is not provided with
It rises in work, operating platform 9 treats the interference of vertical columns.
Preferably, to move column to be fixed, to enter column space more convenient, and rotation section and spacing are greater than to solid
Two support rods for determining column outer diameter are arranged on the top or side of lower channel.
Optionally embodiment, referring to Fig. 1 and Fig. 2, support rod includes main support rod 41 and secondary support rod 42, main branch
It is provided with rotation section on strut 41, is provided with ladder 5 on secondary support rod 42.Main support rod 41 is mainly used for undertaking support post
Work, therefore ladder 5 is arranged on secondary support rod 42.
Specifically, being connected between main support rod 41 and two root pair support rods 42 by more support frames 16, support frame 16
Both ends are separately connected main support rod 41 and secondary support rod 42, to increase the stability between main support rod 41 and secondary support rod 42.
Preferably, referring to fig. 2 and Fig. 3, there are two the struts of pulley to be located at prolonging for column column diameter for setting on rotation section
On long line, all support rods and support frame 16 are respectively positioned on the side for the diameter that rotation section is aligned, and column to be fixed is by rotating
The other side for the diameter that portion is aligned moves into the top of vertical columns, and such rotation section is in the process for turning to vertical columns
In will not be supported the blocking of bar and support frame 16.It can be seen that support frame 16 is located at the lower section of rotation section, rotation section in Fig. 2
Support frame 16 can't cause any obstruction to rotation section in rotation process, and in Fig. 3, dotted line indicates that rotation section turns to and consolidated
When determining above column, the stop position of wirerope 3, in the case where vertical view, it can be observed that dotted line is away from nearest support frame 16
Between there are gap, which has ensured that wirerope 3 will not be supported the blocking of frame 16.
A kind of antiaircraft gun billboard column construction cylinder construction process, comprising the following steps:
S1: billboard column is segmented and in the fixed convergence piece of each section of column joining place；
S2: fixed lowermost end column, and install the operating platform and platform lifting structure；
S3: operating platform is promoted to by vertical columns top and fixation by platform lifting device；
S4: tower crane is fixed on corresponding position；
S5: will be connected above upright lifting to be fixed to vertical columns and by convergence piece and vertical columns by tower crane
It connects；
The repetitive operation of S6:S3-S5 step is at least once；
S7: removal platform lifting structure, operating platform and tower crane.
This method specifically includes the following contents, first to be indoors segmented billboard column and in each section of column joining place inner wall
Method pulling plate is welded and fixed；First segment column is fixed after the column that each section is handled well is transported to construction site, it will by hanging calabash
Operating platform is promoted to first segment column top, screws bolt between anchor ear annular element for operating platform and first segment column column
Body is fixed；After operating platform is set, tower crane is built by side on the operational platform；By tower crane by the second section upright lifting, stand behaviour
Make the people on platform for the second section column movement and is aligned with first segment column；People are risen to vertical by the ladder of column body
Column joining place is simultaneously fixed ring flange by bolt；After second section column fixes, people are by being arranged on tower crane support rod
Ladder rises to the second section the upper end of the column and will hang calabash and is fixed on the second section column, and pine turns the bolt between anchor ear annular element will
Operating platform is separated with first segment column cylinder, by hang calabash by operating platform be promoted to the second section column top and by operation it is flat
Platform is fixed with the second section column；It is promoted by tower crane and all columns to be hoisted is installed；After column is set, first removal tower crane,
Operating platform is down to ground by hanging calabash later.
Specifically, billboard column cylinder is carried out segmentation cutting processing with 2-3 meters.
Existing column multi-pass crosses welding manner connection, needs to build large-scale welding equipment at the scene and carries out welding procedure,
Be located outside when increasing construction cost, while welding column, outdoor construction rain and wind to the firmness of welding procedure all
Have a great impact, the security performance of billboard cannot just ensure, be to be fastened by bolts method between each section of column of this method
Blue disk realizes connection, reduces construction cost without being equipped with large-scale welding equipment, bolt connecting mode is by outdoor weather condition
It influences small.
It is to be fastened by bolts ring flange to realize connection between each section of column of this method compared to each section of column is welded to connect
, each section of column can also utilize again after removal.
This method carries out the welding of convergence piece in indoors, avoid outdoor construction and rain with wind to welding procedure
Caused by negatively affect, ensured the stability of billboard.
Slow, the long construction period of existing column cylinder construction, can just be built by generally taking 7 days by 12-15 meters, pass through we
Method can generally reach the 10-15 meters of columns of installation in 1 day.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
