Described climbing form system use all-steel big shuttering, described embedded part system include bolt embedment PVC sleeve pipe, high-strength bolt and Stressed bolt, described support body system include hook connecting base, climbing support, climbing frame fix pin plate, template movement device, operation put down Platform, guard rail and protection network.
Described climb in flowchart process, sleeve pipe is through in the preformed hole of inner and outer template, by the high-strength spiral shell of hook connecting base Bolt is through in sleeve pipe, by sleeve pipe crimp during to prevent casting concrete;
If the high-strength connecting bolt of hook connecting base and reinforcing bar have conflict, after suitable for reinforcing bar shifting processing, carry out matched moulds;
The electronic control station that climbs has special messenger to operate, and often whether group creeping formwork sets special messenger and keep an eye on and synchronize, and finds asynchronous, adjusts in time;
Creeping formwork climb next layer in place after remove bottom hook connecting base, turnover use;
Creeping formwork climb in place after check that the absolute altitude that climbs is whether consistent, need to be finely adjusted time inconsistent, whole climbing frame is adjusted to same Absolute altitude, errorless after with pin plate, creeping formwork is fixed.
Creeping formwork must be fastened seat belts and wear necessary guarding articles when installing embedded part, hanging seat.High-strength bolt connects necessary Tighten.Concrete strength must arrive more than 15MPa, can climb.
Creeping formwork is also improved to electronic creeping formwork on the basis of former hydraulic climbing formwork by the present invention, and its reliability is high, speed is fast, event Barrier rate is low.Stencil design height 4.1m, concreting height 4 meters, for preventing from pouring spillage, wraps under template when pouring every time 100mm and between the structural top edge poured and template sticking two-faced adhesive tape.External mold uses four groups of creeping formworks to climb simultaneously, interior Mould uses electric expansion bobbin mould to climb with electronic climbing frame simultaneously, and inner and outer template uses all-steel big shuttering.
In the present invention, electronic climbing form frame body portion uses shaped steel cancelled structure, support body height overall 9.95m, width 2 meters, creeping formwork Being connected by steel pipe truss and scaffolding steel pipe between support body is an entirety, and creeping formwork support body is provided with the demoulding, template cleaning, is coated with The climb operation platform of brush releasing agent, the top operating platform of matched moulds and bottom.Die head is provided with concreting and reinforcing bar The two-layer operating platform of colligation, climbing form frame body perimeter defense uses totally-enclosed punched-plate steel plate protection network, and total closed height is 11.5m.Exterior sheathing perimeter defense uses safety net and the protection of Dense mesh screen Double all-sealed, and total closed height is 4m.
In the present invention, support body Specifeca tion speeification index is as follows:
Designation Model: DDPM-4.0 motor-driven chain hoist is from creeping formwork;
Support body supporting span :≤3.0 meters (spacing of adjacent embedded part point);
Support body height: 9.9 meters;
Support body width: 2.0m;
The operation number of plies and construction loads: template platform≤1.5kN/m2, hydraulic operation platform≤3kN/m2, end platform≤1.5kN/ m2。
The DDPM-4.0 motor-driven chain hoist related in the present invention is to promote creeping formwork support body by motor-driven chain hoist from climbing of creeping formwork System and realize.The upper end of motor-driven chain hoist is hung on the top cross-bar of creeping formwork, and lower end is hung on the boom hoist cable of climbing frame, steel wire The other end of rope is fixed on the hook connecting base of creeping formwork.The rising shrinking drive creeping formwork support body of motor-driven chain hoist, works as climbing form frame Body climb first (top) hook connecting base time, creeping formwork support body is fixed on this hook connecting base by fixing pin plate, Creeping formwork support body is made to enter into normal duty.Motor-driven chain hoist creeping formwork is mainly by climbing form frame system system, template system, electromotive inverted Chain promotes system, electric control system is constituted.
The safety in production, the modern-style construction measure that relate in the present invention are as follows:
1, construction is required in strict accordance with relevant rule of operation and project security management.
When 2, propping up modulo operation, should there is reliable foothold and face limit safety prevention measure.
3, forbidding to walk on the beam steel that colligation is good during construction, hurting sb.'s feelings in case falling.
4, during form removal, beam slab mould answers block-by-block to dismantle, and must not loosen in flakes, prizes or forget about it.
In the present invention it should be noted that quality problems and processing method as follows:
1, before model sheetinstallat, design drawing and structure drawing, unwrapping wire figure should be familiar with.
2, reasonably selecting model sheetinstallat order, ordinary circumstance lower bolster is installed from bottom to up, in installation process, and can If temporary support holds template, to be installed complete and correct errorless after just fix.
3, model sheetinstallat should be with the work post close fit such as reinforcing bar binding, hydropower installation.
4, template should check in installation process more, notes the sectional dimension of perpendicularity, absolute altitude and each several part.Form joint Should be tight, what gap was big to block up tight.
5, during casting concrete, it should be noted that observe the situation after template load-bearing, find that displacement, tympanites, spillage, support loosen Etc. phenomenon, should adopt an effective measure in time and be processed.
Above embodiments of the invention are explained in detail, but the present invention is not limited to above-described embodiment, in ability In the ken that territory those of ordinary skill is possessed, it is also possible to make various change on the premise of without departing from present inventive concept Change.
