[0002] A megastructure refers to a structure in which the entire structure is composed of giant rods such as giant columns, giant beams and giant supports to form a space truss. The supports of adjacent facades meet at the corner columns to form a giant space truss structure. With the continuous evolution of the structural system of super high-rise buildings, the mega-column structural system has achieved a greater height span of super high-rise buildings due to its excellent vertical bearing capacity and lateral stiffness, as well as clear force transmission path and high material utilization efficiency. Therefore, it has been increasingly widely used in modern super high-rise buildings. Mega columns are usually concrete-filled steel tube columns (CFT) or steel-reinforced concrete columns (SRC). They have the characteristics of large cross-sectional size and high height, and are also difficult to construct. Formwork is the key to the construction of mega columns. Giant column formwork usually adopts large-area integral steel formwork of 3m-6m, and cooperates with multiple stiffening ribs, giant purlins, and high-strength tension screws to form a stable tension formwork system. Due to the significant increase in the size and weight of the giant column formwork, the difficulty of lifting, positioning, and fine-tuning it has increased significantly. Traditional electric hoist lifting and manual adjustment and positioning methods cannot bear its weight.

[0065] Please focus on Figures 2 to 3 The embodiment of the present invention provides a giant column formwork self-climbing device 300, comprising two formwork panels 310 arranged opposite to each other and a formwork support assembly 320 thereof. The formwork support assembly 320 comprises a plurality of vertical keels 321 arranged on the outside of each formwork panel 310, and a plurality of transverse keels 322 arranged on the outside of each vertical keel 321. It also comprises an upper support mechanism connected to the formwork support assembly 320, the upper support mechanism being hingedly connected to a lower support mechanism through a double-acting hydraulic cylinder 370 hinged thereto, and the double-acting hydraulic cylinder 370 being distributed vertically.

[0066] The upper support mechanism includes an upper bracket 330 and a micro-translation assembly 380 and a column attachment assembly 390 connected in sequence at one end thereof, a guide suspension 350 suspended at the other end of the upper bracket 330, and the guide suspension 350 and the upper bracket 330 at its end are arranged on the formwork support assembly 320. Specifically, the guide suspension 350 of the upper support mechanism and the end of the upper bracket 330 are arranged on the transverse keel 322 of the formwork support assembly 320, and the column attachment assembly 390 of the upper support mechanism is used to be arranged on the inner vertical column 221 of the platform frame 220 of the integral climbing steel platform 200. The guide suspension 350, the upper bracket 330 and the transverse keel 322 can be welded or bolted. In order to improve the supporting stability of the formwork panel 310, the upper bracket 330 can be an angle frame, including a transverse frame and an oblique frame distributed at an acute angle above it, one end of the transverse frame (the end away from the formwork panel 310) is used to be set on the inner vertical column 221 of the platform frame 220 of the integral climbing steel platform 200 through the attached column assembly 390, and the other end of the transverse frame (the end close to the formwork panel 310) and the oblique frame on its side are respectively connected to the transverse keel 322.

[0067] The lower support mechanism includes a lower support 340 and a column attachment assembly 390 connected to one end thereof. The column attachment assemblies of the upper and lower support mechanisms are distributed on the same side. The other end of the upper support 340 is sequentially connected to a micro-translation assembly 380 and a guide pulley 360, and the guide pulley 360 is arranged on a guide suspension 350. The column attachment assembly 390 of the lower support 340 is used to be arranged on the inner vertical column 221 of the platform frame 220 of the integral climbing steel platform 200; wherein the lower support 340 can be an angle frame, including a transverse frame and an oblique frame distributed at an acute angle below it, one end of the transverse frame (the end away from the template panel 310) is connected to the column attachment assembly 390, and the other end of the transverse frame (the end close to the template panel 310) and the guide pulley 360 at one end of the oblique frame on its side are arranged on the guide suspension 350. wherein the double-acting hydraulic cylinder 360 can be replaced by a bidirectional cylinder, or other types of hydraulic cylinders with telescopic functions.

In order to improve the reliability of the connection between the column attachment assembly 390 and the inner vertical column 221, the cross-sectional shape on the inner vertical column 221 can be H-shaped, so that the two rollers 392 of the column attachment assembly 390 slide and limit between the flange plates on both sides of the web of the inner vertical column 221, so as to improve the reliability of the sliding connection and support between the column attachment assembly 390 and the inner vertical column 221, and avoid the separation between the two. The screw 393 can be a T-shaped screw, and the rod seat 394 can be a nut. The attached column assembly 390 has two functions of sliding and locking relative to the inner vertical column 221. When the screw rod 393 passes through the inner vertical column 221 and is threadedly connected to the rod seat 394 of the attached column assembly 390, the attached column assembly 390 is locked relative to the inner vertical column 221. At this time, the roller 392 of the attached column assembly 390 is supported on the inner vertical column 221, that is, the roller 392 is stationary; when the screw rod 393 is removed from the rod seat 394 and removed from the inner vertical column 221, the attached column assembly 390 is unlocked relative to the inner vertical column 221. At this time, the roller 392 of the attached column assembly 390 can slide relative to the inner vertical column 221.

[0071] Please focus on Figure 3 , wherein the specific structure of the connection node between the lower bracket 340 and the platform frame 220 is as follows: one end of the transverse frame of the lower bracket 340 is connected to the column assembly 390 by bolts, and the two rollers 392 of the column assembly 390 are slidably set on the inner vertical column 221 of the platform frame 220; the other end of the transverse frame of the lower bracket 340 and one end of the oblique frame on its side are respectively connected to a connecting plate 381 on one side of the micro-translation assembly 380 by bolts, and the other side connecting plate 381 of the micro-translation assembly 380 is connected to the base of the guide pulley 360 by bolts, and the pulley of the guide pulley 360 is in contact with the guide suspension 350.

[0072] Please refer to Figure 2 When the column assemblies 390 of the lower bracket 240 are locked relative to the inner vertical column 221 of the platform frame 220, the guide pulley 360 of the lower bracket 340 is supported on the guide suspension 350; when the column assemblies 390 of the lower bracket 330 are unlocked relative to the inner vertical column 221 of the platform frame 220, the guide pulley 360 of the lower bracket 340 can slide on the guide suspension 350.

[0073] Please refer to Figure 1 The embodiment of the present invention provides a construction method of a giant column formwork self-climbing device 300, comprising:

[0074] Step 401, please refer to Fig.11 , Initial installation of the giant column formwork self-climbing device: The giant column formwork self-climbing device 300 is installed between the inner vertical columns 221 of the platform frame 220 of the integral climbing steel platform 200 of the giant column 100 that has been cast and constructed. This initial installation is the initial state of the giant column formwork self-climbing device 300.

[0075] Specifically, the formwork panel 310 is fitted or aligned on the giant column 100 that has been cast. The upper and lower support mechanisms are set on the inner vertical column 221 of the platform frame 220 of the integral climbing steel platform 200 through the pulleys 392 of the respective column attachment assemblies 390, and the screw rods 393 of each column attachment assembly 390 are threadedly connected to the rod seat 394 through the inner vertical column 221; at this time, the column attachment assembly 390 is in a locked state relative to the inner vertical column 221; the guide pulley 360 of the lower support mechanism is contacted and set on the guide suspension 350. At this time, the formwork panel 310 is attached to the platform frame through the formwork support assembly 320, the upper and lower support mechanisms and the double-acting hydraulic cylinder 370. At this time, the guide pulley 360 of the lower support mechanism supports the formwork support assembly 320 and the formwork panel 310 through the guide suspension 350. The upper and lower supporting mechanisms between the platform frame 220 on each side and the template panel 310 include but are not limited to one. The more the upper and lower supporting mechanisms are, the higher the supporting reliability of the template panel 310 is.

[0076] Step 402, please refer to Fig.12 , the guide pulley of the lower support mechanism is separated: by adjusting each micro-translation assembly 380 on the lower support mechanism, the guide pulley 360 of the lower support mechanism is moved away from the guide suspension 350. That is, the guide pulley of the lower bracket 340 is separated from the guide suspension 350. At this time, the template panel 310 is attached to the platform frame through the template support assembly 320, the upper support mechanism, the double-acting hydraulic cylinder 370 and the lower support mechanism. The micro-translation assembly 380 needs to be locked when adjusted forward and backward.

[0077] Step 403, please refer to Fig.13 , Formwork panel demoulding: By adjusting the micro-translation components 380 of the upper support mechanism, the upper support mechanism, the formwork support component 320 and the formwork panel 310 move toward the platform frame 220, so that the formwork panel 310 is separated from the giant column 100 that has been cast. At this time, the double-acting hydraulic cylinder 370 is hinged and rotated relative to the upper and lower brackets.

[0078] Step 404, please refer to Fig.14 , Unlocking the attached column assembly of the upper support mechanism: Remove the screw rod 393 on the attached column assembly 390 of the upper support mechanism from the inner vertical column 221, so that the attached column assembly 390 of the upper support mechanism is in an unlocked state relative to the inner vertical column 221. At this time, the screw rod 393 can be directly connected to the rod seat 394 without passing through the inner vertical column 221 to avoid the screw rod 393 from being lost.

[0079] Step 405, please refer to Fig.15, the upper support mechanism climbs: keep the column assembly 390 of the lower support mechanism in a locked state relative to the inner vertical column 221, and the column assembly 390 of the upper support mechanism in an unlocked state relative to the inner vertical column 221, control the double-acting hydraulic cylinder 370 to extend, so that the pulley 392 of the column assembly 390 of the upper support mechanism slides upward along the inner vertical column 221 to make the upper support mechanism move upward, that is, the upper support mechanism climbs, so that the upward movement of the upper support mechanism drives the template support assembly 320 and the template panel 310 to move upward synchronously, and realizes the staged climbing of the template panel 210. The staged climbing refers to climbing in sections.

[0080] Step 406, please refer to Fig.16 , the attached column assembly of the upper support mechanism is locked: the screw rod 393 on the attached column assembly 390 of the upper support mechanism is passed through the inner vertical column 221 and bolted to the rod seat 394, so that the attached column assembly 390 of the upper support mechanism is in a locked state relative to the inner vertical column 221.

[0081] Step 407, please refer to Fig.17 , Unlocking the attachment column assembly of the lower support mechanism: Remove the screw rod 393 on the attachment column assembly 390 of the lower support mechanism from the inner vertical column 221, so that the attachment column assembly 390 of the lower support mechanism is in an unlocked state relative to the inner vertical column 221. At this time, the screw rod 393 can be directly connected to the rod seat 394 without passing through the inner vertical column 221 to avoid the screw rod 393 from being lost.

[0082] Step 408, please refer to Fig.18 , the lower support mechanism climbs: keep the column assembly 390 of the upper support mechanism in a locked state relative to the inner vertical column 221, and the column assembly 390 of the lower support mechanism in an unlocked state relative to the inner vertical column 221, control the double-acting hydraulic cylinder 370 to shorten, so that the pulley 392 of the column assembly 390 of the lower support mechanism slides upward along the inner vertical column 221 of the platform frame 220 to move the lower support mechanism upward. At this time, when the guide pulley 360 of the lower support mechanism contacts the guide suspension 350, the guide pulley 360 moves upward along the guide suspension 350; when the guide pulley 360 of the lower support mechanism does not contact the guide suspension 350, the guide pulley 360 directly follows the upward movement.

[0083] Step 409, please refer to Fig.19 , locking the attached column assembly of the lower support mechanism: passing the screw rod 393 on the attached column assembly 390 of the lower support mechanism through the inner vertical column 221 and bolting it to the rod seat 394, so that the attached column assembly 390 of the lower support mechanism is in a locked state relative to the inner vertical column 221.

[0084] Step 410, looping through steps 404 to 409, causing the upper and lower support mechanisms to alternately climb, thereby driving the template panel 310 to climb upward to a predetermined floor height through the climbing of the upper support mechanism. Figure 20 to Figure 21 During the alternating climbing process of the upper and lower supporting mechanisms, one of the upper and lower supporting mechanisms is always connected to the inner vertical column 221 of the platform frame 220, thereby ensuring the reliability, stability and safety of the giant column formwork self-climbing device.
