The construction method of the climbing formwork comprises the following steps:
step S100, placing the first supporting portion 14 of the supporting platform 10 and the second supporting portion 34 of the construction platform 30 in the reserved hole 3 of the concrete shear wall 2. Specifically, the first support leg 140 of the first support portion 14 extends into the reserved hole 3, so as to provide a support function for jacking the support platform 10. The second supporting leg 340 of the second supporting portion 34 extends into the reserved hole 3, so that the construction platform 30 can be prevented from accidentally falling.
Step S102, the driving unit 40 is started to drive the construction platform 30 to ascend by a first distance, and the construction platform 30 temporarily hovers. The construction platform 30 is lifted for a certain distance to ensure that the second support part 34 is lifted for a certain height, so that the second support leg 340 can normally extend out of the reserved hole 3 of the concrete shear wall 2.
Step S104, retracting the second support portion 34 into the construction platform 30, and climbing the construction platform 30 along the support pillar 20 under the action of the driving portion 40 until the construction platform 30 climbs to a preset height.
And S106, extending the second supporting part 34 into the reserved hole 3 on the concrete shear wall 2, starting the driving part 40, and driving the supporting platform 10 to ascend for a second distance. The driving part 40 moves along the supporting column 20 and can be connected with the supporting column 20, so that the driving part 40 can drive the supporting column 20 to lift, and then the supporting platform 10 is lifted.
Step S108, retracting the first supporting portion 14 into the supporting platform 10, wherein the supporting platform 10 climbs along with the supporting column 20 under the action of the driving portion 40 until the supporting platform 10 climbs to a designated height, and retracting the first supporting portion 14 into the supporting platform 10.
Step S110, extending the first supporting part 14 into the reserved hole 3 on the concrete shear wall 2 to prepare for entering a construction stage. After the construction platform 30 and the support platform 10 are both placed, a worker sets the construction platform 30 for construction work.
The climbing process of the climbing formwork device 1 will be described in detail as follows:
when the constructor is doing normal building construction work, the first supporting leg 140 of the supporting platform 10 and the second supporting leg 340 of the construction platform 30 are both laid in the reserved hole 3 of the concrete shear wall 2. And after the construction process of the current floor of the building stair structure is finished, the climbing formwork device 1 starts climbing. After all the working conditions of the climbing formwork device 1 are checked to be good and correct, the climbing formwork device 1 starts climbing.
The driving element 42 is started, the plunger rod of the jacking cylinder starts to extend out, the first stop block of the lower climbing shoe 44 enters the fixing groove 22 of the support column 20 for supporting, the position of the lower climbing shoe 44 is unchanged, the bearing part 36 is pushed to move upwards in the process of jacking the cylinder, the construction platform 30 connected with the bearing part 36 is further enabled to move upwards, and at the moment, the upper climbing shoe 46 also moves upwards under the driving of the construction platform 30. When the construction platform 30 is lifted for 5cm, the driving member 42 stops lifting, and the construction platform 30 temporarily hovers. The step is the pre-lifting of the construction platform 30, and because the height of the reserved hole 3 of the concrete shear wall 2 is greater than that of the second support leg 340, during actual construction, the second support leg 340 is lifted to leave the lower wall of the reserved hole 3, so that the second support leg 340 retracts without obstacles.
When the construction platform 30 is temporarily suspended, the second support part 34 of the construction platform 30 starts to work, the support cylinder power source-hydraulic pump station is started to prepare for oil return of the second drive cylinder 344, the plunger rod of the second drive cylinder 344 retracts and is linked with the retraction of the second support legs 340, and when all the second support legs 340 retract to the second bottom plate 32, the second drive cylinder 344 stops working. When all the four second support legs 340 of the construction platform 30 are retracted into the second leg locking grooves 341, the formal climbing process of the construction platform 30 is performed.
The first stop of the lower climbing shoe 44 enters the retaining groove 22 of the support column 20, and the first stop rests on the inner bottom surface of the retaining groove 22. The jacking cylinder as the driving piece 42 is set to extend, and when the extending range of the jacking cylinder reaches a set value, the jacking cylinder automatically stops extending. Then, the jacking cylinder performs oil return operation, the cylinder plunger starts to retract, at this time, the wrench position of the lower climbing shoe 44 is inclined downwards, the first stopper is moved out of the fixing groove 22 of the supporting column 20, and the lower climbing shoe 44 starts to retract along with the plunger rod of the jacking cylinder, that is, the lower climbing shoe 44 moves upwards along the supporting column 20. During the ascending process of the lower climbing shoe 44, the second stopper of the upper climbing shoe 46 is positioned in the fixing groove 22 of the support column 20 to bear the load of the construction platform 30. And when the retraction stroke of the jacking oil cylinder reaches a set value, the plunger rod of the jacking oil cylinder returns to the original position, and the next cycle of jacking operation is carried out again. Generally, the climbing height of the construction platform 30 is about 4m, the jacking cylinder needs to perform telescopic cylinder operation for 10 cycles, and when the jacking cylinder extends, the first stop block of the underneath climbing shoe 44 is located in the fixing groove 22 of the support pillar 20 and is responsible for supporting the whole weight of the construction platform 30. The upper climbing shoe 46 can prevent the construction platform 30 from suddenly dropping, and when the lower climbing shoe 44 is not stressed, for example, when the lower climbing shoe 44 is lifted along the supporting column 20 along with the retraction of the plunger rod of the jacking cylinder, the second stopper of the upper climbing shoe 46 is located in the fixing groove 22 of the supporting column 20 and is responsible for supporting the whole weight of the construction platform 30.
When the construction platform 30 climbs to a preset height, the second support leg 340 on the construction platform 30 is ensured to be capable of extending into the reserved hole 3 of the concrete shear wall 2. At this time, the construction platform 30 is instructed to stop climbing, and the jacking oil cylinder stops stretching.
Next, the hydraulic pump station of the second supporting portion 34 of the construction platform 30 is started, the second driving cylinder 344 is ready for oil feeding, the plunger rod of the cylinder extends out to drive the second transmission link 343 to move, so that the second supporting legs 340 extend out of the second leg locking grooves 341 and then enter the reserved holes 3 of the concrete shear wall 2, and after checking that all the second supporting legs 340 enter the reserved holes 3, the second driving cylinder 144 stops working. The construction platform 30 is ready for a lowering operation so that the second support legs 340 of the construction platform 30 rest on the bottom surface of the reserved hole 3 of the concrete shear wall 2. The jacking oil cylinder is ready for oil return operation, the plunger rod of the jacking oil cylinder retracts, the construction platform 30 starts to descend at a low speed, and after the second support leg 340 of the construction platform 30 is safely placed, the supporting platform 10 is ready for lifting operation. The steps here are to ensure that the second supporting leg 340 of the construction platform 30 is placed at the bottom of the reserved hole 3 of the concrete shear wall 2, and the height of the reserved hole 3 is larger than that of the corresponding second supporting leg 340, so that the second supporting leg 340 may exist in the reserved hole 3 under the condition of being suspended, at this time, the construction platform 30 is firstly lowered by a certain distance, so that the second supporting leg 340 can be placed at the bottom of the reserved hole 3, and the construction stability and safety are improved.
After the second support legs 340 of the construction platform 30 are safely rested, the support platform 10 is prepared for a lifting operation. The lifting of the support platform 10 also includes pre-lifting and formal lifting, as follows:
the wrenches of the upper climbing shoe 46 and the lower climbing shoe 44 are reversed, at this time, the first stop block of the lower climbing shoe 44 enters the fixing groove 22 of the supporting column 20, the first stop block abuts against the upper surface of the fixing groove 22 to provide supporting force for jacking the supporting platform 10, and the second stop block of the upper climbing shoe 46 enters the fixing groove 22 of the supporting column 20 to prevent the supporting platform 10 from accidentally falling. And (3) performing oil return operation on the jacking oil cylinder, retracting a plunger rod of the jacking oil cylinder, lifting the lower climbing shoe 44 connected with the lower part of the plunger rod, enabling a first stop block of the lower climbing shoe 44 to enter the fixing groove 22 of the supporting column 20, and lifting the supporting column 20 under the jacking of the lower climbing shoe 44. When the lifting height of the supporting platform 10 is 5cm and the bottom surface of the first supporting leg 140 is completely separated from the reserved hole 3 of the concrete shear wall 2, the first supporting leg 140 of the supporting platform 10 is ready to be completely retracted into the first bottom plate 12. The hydraulic pump station of the first support portion 14 is activated, the first driving cylinder 144 performs an oil return operation, and the cylinder plunger retracts to drive the first transmission link 143 to move, so that the first support leg 140 moves along the first leg locking groove 141 and retracts into the first base plate 12. When the first support leg 140 is fully retracted into the first base plate 12, the first drive cylinder 144 is deactivated and the support platform 10 enters the final lift phase.
Setting the retraction displacement of the jacking oil cylinder to enable the oil cylinder to retract to the initial position, and then performing the extension operation of the jacking oil cylinder. When the jacking cylinder performs rod extending operation, the second stopper of the upper climbing shoe 46 is positioned in the fixing groove 22 of the supporting column 20, and plays a role in supporting the construction platform 30. The lower climbing shoe 44 descends along the support post 20 as the ram rod of the ram extends. After the jacking oil cylinder is extended to the position to prepare for the rod retracting operation, the first stop block of the lower climbing shoe 44 enters the fixing groove 22 of the supporting column 20. When the plunger rod of the jacking cylinder retracts, the first stopper of the lower climbing shoe 44 drives the supporting column 20 to move upwards, and further drives the supporting platform 10 to move upwards. After ten times of oil return-oil inlet (i.e., rod contraction and rod extension) operation flows, the supporting platform 10 is lifted to a specified height, and the jacking cylinder stops working. At this time, the elevation of the bottom surface of the first support leg 140 of the support platform 10 is slightly higher than the elevation of the bottom surface of the reserved hole 3 of the concrete shear wall 2, and preparation work for extending the first support leg 140 is started. The hydraulic pump station of the first supporting portion 14 is started, and the plunger rod of the first driving cylinder 144 extends out to drive the first supporting leg 140 into the reserved hole 3 of the concrete shear wall 2. After the first support leg 140 extends out by a predetermined length, the first driving cylinder 144 stops operating.
The support platform 10 is then ready to be lowered, ensuring that the first support leg 140 of the support platform 10 rests within the reserved opening 3 of the concrete shear wall 2. Since the height of the reserved hole 3 of the concrete shear wall 2 is greater than the height of the first support leg 140, the first support leg 140 may have a suspended state in the reserved hole 3 of the concrete shear wall 2, that is, the first support leg 140 is not laid on the reserved hole 3. Therefore, the support platform 10 is lowered by a predetermined height, so that the first support leg 140 abuts against the bottom surface inside the reserved hole 3, thereby ensuring the stability of the support platform 10. Specifically, the jacking cylinder is ready for extending rod operation, the lower climbing shoe 44 connected with the plunger rod of the jacking cylinder descends, and the support platform 10 descends along with the lower climbing shoe 44 until the first support leg 140 of the support platform 10 is placed in the reserved hole 3 of the concrete shear wall 2. After the supporting platform 10 is placed and works, the jacking oil cylinder and the power source liquid pump station stop working.
