Construction personnel's station operation in platform hanging basket 602, position, platform are constant, and framework of steel reinforcement flows downward, and people does not move, as vertical
Assembly line, construction safety, labor intensity are small；
Step 6: every to have bound a section diaphragm wall framework of steel reinforcement, decentralization is primary；
Bound final section diaphragm wall framework of steel reinforcement, under discharge last time diaphragm wall framework of steel reinforcement, diaphragm wall framework of steel reinforcement
It occupies stably on 11 bottom of continuous wall groove, absolute altitude is inspected for acceptance after qualification, and draw-string pin of the wirerope 10 at heavy frame 14 is pulled, and is extracted out
Wirerope 10；Specifically, framework of steel reinforcement binds 3000mm high every time, and often tying up a section is 1500mm high.
Step 7: after qualification of inspecting for acceptance, pouring continuous wall concrete.
Pumping pin rope 17 is connected on solution rope pin 8 in construction method, by pulling pumping pin rope 17 so that rope pin 8 and wirerope will be solved
10 and heavy frame 14 be detached from, to extract wirerope 10 out.10 lower end of wirerope makes a rope sling, specifically, 10 lower end of wirerope
After rope 18 upwards, upwards after wirerope 10 curve a semicircle, half circle imbeds rope sling, fixed with pumping pin rope 17,
The ring part of pin obliquely and ties up on pumping pin rope 17, and specific pumping pin rope 17 is cotton cord, and the other end of cotton cord is pricked
In the pillar (not shown) on concrete floor 13；In addition rope 18 is restricted around 14 fashioned iron crossbeam of heavy frame, 3 end is tied
External application solution rope pin 8 is fixed；Between wirerope 10, steel wire cable 18, with 3 contact position of fashioned iron crossbeam with steel paunch mat (in figure not
Show) it pads.Iron wire 802 passes through through-hole 801, and rope 18 is fixed by solution rope pin 8.
Such as Fig. 6, the platform 2 in the present embodiment on preferred mode fashioned iron crossbeam 3 is grating type profile steel blanking platform, fashioned iron
It is hung below crossbeam 3 and sets Hanging Basket 6 and its platform hanging basket 602.
As shown in fig. 7, platform 2 selects the wooden scaffold board of 50mm thickness in the present embodiment；Fashioned iron crossbeam 3, which is removed, selects N20 work
Word steel, 2000 ㎜ of spacing.Section longitudinal beam 4 generally selects N16 I-steel, 800~1000 ㎜ of spacing；Steel column 5, which is removed, selects N20
260 × 10 steel pipe of I-steel, 2000 ㎜ of spacing, I-steel used in fashioned iron crossbeam 3, section longitudinal beam 4 and steel column 5 it is big
Rootlet obtains according to calculating in actual use.The sunpender 601 of Hanging Basket 6 selects 48 × 3 steel pipe spacing, and railing 603 selects 48 × 2.7
900 ㎜ of steel pipe spacing, platform hanging basket 602 select the wooden scaffold board of 50mm thickness, are layered on to be formed on the horizontal steel tube of cradle bottom and put down
Platform.Specifically, the steel pipe under backing steel pipe, that is, platform hanging basket 602 holds the wooden scaffold board of 50mm thickness, forms platform.Platform
Steel pipe selects 48 × 3 ㎜ of spacing 800mm~1000 under plate；The lifting capacity size of hoist engine 9 is determined by calculating；Hoist rope
10 specifications are by calculating determination, 1500 ㎜ of spacing；12 thickness of steel plate, 20~30 ㎜；The strength grade of concrete of concrete floor 13 is
150 ㎜ of C25 thickness；Heavy frame 14 is N14 I-steel and crossbeam (1500 ㎜ of spacing) downhand welding, weld four longitudinal direction N14 I-steel (with
1 number of rows of main reinforcement, centre to centre spacing are identical), on longitudinal I-steel, straight thread set is welded in vertical 1 corresponding position of main reinforcement of wall
Pipe, to fix the position of the vertical main reinforcement 1 of wall.
Diaphram wall steel bar segmentation formula constructing device of the invention and construction method are a kind of vertical diaphram walls
Framework of steel reinforcement does not need great prefabricated place for scene binding, and vertical direction binds one section and transfers one section, horizontal reinforcement
It is bound in the main reinforcement of vertical direction with horizontal reinforcement by design requirement, a section framework of steel reinforcement is completed, and a section is transferred.It is prefabricated to account for
Ground lacks, small to lifting capacity, height, the working radius requirement of hoisting machinery, and safety, worker bind operation, base in platform hanging basket
This is not necessarily to shift position in situ, and concentration does not change, vertical Hanging type assembling reinforcement skeleton is indeformable, upright position is easy to control,
The dynamic rebuffed phenomenon of skeleton Huang is prevented, has prevented phenomena such as not going under being rebuffed due to skeleton, reveal muscle, collapse hole, prevented diaphragm wall
Press from both sides the phenomenon of soil.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
