Described support bar 4-2 is provided with the limiting card 4-4 for restriction hydraulic jack 4-1 stroke.Structure can guarantee that the stroke that promotes is consistent thus, thereby guarantees the levelness of whole plate device 1 in work progress.
The main material of making:
Template is vertically assembled successively by the standard steel template of width 15cm, adopts U-shaped to link between template and connects; U-shaped hoisting frame 2 and tripod 3-2 adopt the channel-section steel material to be welded; Enclose purlin and contact beam 5 and also select the channel-section steel material to make, and be processed into the arc shape that adapts with the silo circle; Support bar 4-2 adopts steel pipe manufacturing; Spider 7 adopts steel plate to make; Annular girder 3-3 adopts the lumps of wood, and casting platform and the platform of wiping one's face adopt wood material.
It is as follows that this device is installed and used process:
One, elder generation about highly about 1.0m, builds first storehouse silo concrete after base surface adopts template formwork erection in bulk, and presses the pre-buried support bar 4-2 of design size in concreting process, and support bar is buried underground and must be guaranteed vertically.
Two, after first storehouse concrete initial set and form removal, this device can be installed:
1, as shown in Figure 3, the placement of first the U-shaped hoisting frame 2 of single Pin being sat on the fence successively, upper beam penetrates on the support bar 4-2, adjust U-shaped hoisting frame, make U-shaped hoisting frame vertically, crossbeam maintenance level and crossbeam axis aim at the silo concrete center of circle, and carry out temporary fixed, support, note making each U-shaped hoisting frame crossbeam to be on the same level elevation face during installation.
2, behind U-shaped hoisting frame 2 installation in position of 2~3 Pin, the vertical upright column 2-1 bolt that successively inside and outside level is enclosed purlin 1-3 and the U-shaped hoisting frame 2 of every Pin links together, and encloses the purlin joint and takes to be welded to connect into whole.
3, inside and outside enclose the purlin installation after, segmentation assembling reinforcement and bury built-in fitting etc. underground is installed inner side template 1-1, outboard template 1-2 successively by number order in advance again.Template must make template tilt about 0.5% in the storehouse when installing, form up big and down small tapering, be beneficial to the demoulding, and template end opening width equals storehouse cylinder concrete wall thickness.
4, after template all installs, again adjusting screw 6 is connected between the inboard column 2-1 bottom and spider 7 of U-shaped hoisting frame 2, and rotating regulating sleeve 6-1 makes plate device reach the design accuracy requirement to adjust adjusting screw 6.
5, tripod 3-2 is bolted on U-shaped hoisting frame vertical upright column 2-1, then lays annular girder 3-3 thereon, lay plank and form casting platform 3-1, safety barrier is installed simultaneously.
6, at casting platform hydraulic jack 4-1 and hydraulic lifting system 4 are installed.
7, adopt at last suspension bracket reinforcing bar 3-5 that the inside and outside platform 3-4 that wipes one's face is welded on the template bottom, safety barrier is installed simultaneously.
8, after inspection, the acceptance(check), can enter the construction of normal concreting and template sliding lifting.
Three, template sliding lifting
1, initial rise
Build a layer concrete in the template, behind about 0.4m height, before the initial set, can begin climbing forms behind about 2.5h.Start hydraulic control panel 4-3 and begin initial rise, make hydraulic jack 4-1 push up 1~2 stroke that climbs, about about 5cm, observe the concrete strength conditions of depanning, and adjust accordingly the climbing speed of hydraulic jack 4-1, then can enter the normal sliding stage.
2, normally sliding
Whenever built a layer concrete, LIFT height of climbing forms, continuous placing successively, and sliding continuously, template sliding lifting speed should be controlled in the 40cm/h.When weather sweltering heat or concreting lap time are longer, should start a hydraulic control panel, sliding 1~2 stroke in 20~30 minutes in every interval.
In the normal sliding stage, the operation such as template sliding lifting, concreting, reinforcing bar binding, built-in fitting are buried underground, extended support bar and depanning concrete surface troweling hockets mutually.
3, the end rises and stops sliding
When concreting during to the following 20cm of the design elevation left and right sides, last layer concrete primary concreting is finished, and concrete must be controlled on the same level face; After last layer concrete is built and finished, continue climbing forms, once sliding every 20~30 minutes, until the template end opening is sliding during to 10~20cm below the Concrete Design end face.
Four, form removable flow process
Form removable is substantially opposite with installation, and program is: oil path control system is removed, and---------regulating screw mandrel and spider removes, and---------enclosing purlin and contact beam and remove---U-shaped hoisting frame dismounting---exposes support bar and cuts off in the internal mold dismounting in the external mold dismounting in the casting platform dismounting in the platform of wiping one's face dismounting.
