[0016] According to another aspect of the present invention, there is provided a construction method for a support device for early dismantling of a formwork for building construction, which is used for the support device for early dismantling of a formwork for building construction, and comprises the following steps:

[0017] Clean the installation surface and install the base on it;

[0018] According to the floor height, the lifting mechanism drives the columns to rise, and the columns drive the main support plate and the side support plate to rise to the specified height;

[0019] After determining the heights of the main support plate and the side support plate, the adjustment mechanism is activated according to the shape requirements of the floor slab to adjust the angles of the side support plates on both sides of the main support plate so that the shape formed by the main support plate and the side support plate is compatible with the floor slab;

[0020] After the adjusting mechanism has adjusted the angle of the side support plate, the locking mechanism is activated to lock the main support plate, the side support plate and the column together.

[0021] The beneficial effects of the present invention are:

[0022] Through the design of the lifting mechanism, the jacking cylinder pushes the column to move vertically. When the column moves, the main support plate and the side support plate on the top are driven up, so that the height of the main support plate and the side support plate is adapted to the height of the floor.

[0023] Through the design of the supporting components, during the formwork installation process, the main keel is installed between the main plates on both sides, the secondary keel is installed on the top of the top plate, and the floor formwork is installed on the side of the secondary keel and above the main keel.

[0024] Through the design of the adjustment mechanism, when it is necessary to adjust the side support plates on both sides to move synchronously, at this time, the locking mechanism is first started to release the locking relationship between the moving frame and the column, and then the motor is started to drive the screw rod to rotate. The screw rod drives the nut moving plate to move vertically through the action of the thread. The vertical movement of the nut moving plate will drive the moving frames on both sides to move vertically through the reinforced connecting plate. The movement of the moving frame will drive the electric push rod and the fixed plate fixed at the bottom of the electric push rod to move vertically, and the fixed plate drives the vertical plate to move vertically. Because the top of the vertical plate is hingedly connected to the sliding sleeve slidably connected to the guide frame, the vertical plate will pull the guide frame and the side support plates on the side of the main support plate when it moves vertically. When the side support plate needs to be adjusted on one side, the locking mechanism is activated, so that the short locking block on the locking mechanism is disconnected from the locking port 1 and the plug-in hole on the vertical plate, thereby releasing the locking relationship between the vertical plate and the moving frame. At the same time, the long locking block on the locking mechanism has not yet disengaged from the locking port 2 on the column, and the moving frame and the column are still in a locked connection state. At this time, the electric push rod is activated, and the electric push rod pushes the fixed plate and the vertical plate to move vertically. When the vertical plate moves vertically, it will pull the side support plate to rotate on the side of the main support plate, thereby achieving the purpose of adjusting the angle of the side support plate on one side.

[0025] Through the design of the locking mechanism, motor two is started, and motor two drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the rotating wheel to rotate, and the rotating wheel drives the track plates on both sides to rotate, and the track plates push the sliding plates one and two sliding plates slidably connected on both sides of the inner cavity to move through the squeezing of the protrusions by the internal slide rails, and the movement of the sliding plates one and two will respectively drive the long locking blocks and the short locking blocks on the sides to move, and the outward and inward movements of the long locking blocks and the short locking blocks realize the card connection and release actions between the moving frame and the column and the vertical plate. At the same time, due to the length difference between the long locking blocks and the short locking blocks, when the long locking blocks and the short locking blocks move outward to realize the card connection action, when the sliding plates When the long locking block and the short locking block continue to move toward the inner cavity, the long locking block will also be separated from the locking mouth 2 and enter the inner cavity. At this time, the movable frame on both sides can be started to move synchronously by the screw rod, so as to achieve the purpose of synchronously adjusting the angle of the side support plates on both sides.

[0026] Through the design of the shielding component, when the reinforced connecting plate moves vertically in the movable opening, the reinforced connecting plate will pull or stretch the shielding cloths on both sides. At the same time, the winding roller of the rolled-up shielding cloth will rotate, thereby realizing the pulling or stretching action of the shielding cloth. When the winding roller rotates, the winding roller will compress the winding spring spring, and the power released by the winding spring spring will drive the winding roller to reset and rotate. It can be used in the construction of prefabricated buildings, green buildings, etc., and has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

The movement of the moving frame 14 will drive the electric push rod 39 and the fixed plate 38 fixed at the bottom of the electric push rod 39 to move vertically. The fixed plate 38 drives the vertical plate 36 to move vertically. Because the top of the vertical plate 36 is hingedly connected to the sliding sleeve slidably connected to the guide frame 35, the vertical plate 36 will pull the guide frame 35 and the side support plate 34 on the main support plate 3 when it moves vertically. 3, thereby achieving the purpose of adjusting the angle of the side support plate 34 on both sides; when it is necessary to adjust the angle of the side support plate 34 on one side, at this time, the locking mechanism is started, so that the short locking block 23 on the locking mechanism is disconnected from the locking hole 1 40 and the plug hole 37 on the vertical plate 36, thereby achieving the purpose of releasing the locking relationship between the vertical plate 36 and the movable frame 14. At the same time, the long locking block 22 on the locking mechanism has not yet disengaged from the locking hole 2 47 on the column 5, and the movable frame 14 and the column 5 are still in a locked connection state. At this time, the electric push rod 39 is started, and the electric push rod 39 pushes the fixed plate 38 and the vertical plate 36 to move vertically. When the vertical plate 36 moves vertically, it will pull the side support plate 34 to rotate on the side of the main support plate 33, thereby achieving the purpose of adjusting the angle of the side support plate 34 on one side.

[0056] The operation process of the locking mechanism is as follows: start motor 2 32, motor 2 32 drives worm 31 to rotate, worm 31 drives worm wheel 30 to rotate, worm wheel 30 drives rotating wheel 27 to rotate, rotating wheel 27 drives track plates 28 on both sides to rotate, track plates 28 push sliding plate 1 20 and sliding plate 21 slidably connected on both sides of inner cavity 15 to move through the internal slide rail 29 squeezing the protrusion 25, the movement of sliding plate 1 20 and sliding plate 21 will respectively drive the long locking block 22 and the short locking block 23 on the side to move, the outward movement and inward movement of the long locking block 22 and the short locking block 23 realize the clamping connection action and the unclamping action between the movable frame 14 and the column 5 and the vertical plate 36, at the same time, due to the length difference between the long locking block 22 and the short locking block 23, the outward movement of the long locking block 22 and the short locking block 23 realizes the clamping connection action. When the long locking block 22 and the short locking block 23 continue to move toward the inner cavity 15, the long locking block 22 will also be separated from the locking opening 47 and enter the inner cavity 15. At this time, the movable frame 14 on both sides can be started to move synchronously by the screw rod 10, so as to achieve the purpose of synchronously adjusting the angle of the side support plates 34 on both sides.

[0057] The operation process of the shielding assembly is as follows: during the vertical movement of the reinforcing connecting plate 13 in the movable opening 49, the reinforcing connecting plate 13 will pull or stretch the shielding cloth 48 on both sides. At the same time, the winding roller of the rolled-up shielding cloth 48 will rotate, thereby realizing the pulling or stretching action of the shielding cloth 48. When the winding roller rotates, the winding roller will compress the winding spring spring, and the power released by the winding spring spring will drive the winding roller to reset and rotate.
