Description

Technical Field

[0001] This invention belongs to the field of building construction machine technology, specifically relating to an integrated formwork lifting device for building construction machines. Background Technology

[0002] In the construction of high-rise and super high-rise buildings, the core tube structure typically serves as the building's main load-bearing and lateral force-resisting system, containing vertical passages such as elevator shafts and pipe shafts. These shaft structures are arranged continuously from top to bottom, forming a continuous vertical cavity. In traditional core tube construction, the formwork inside the shafts is usually constructed using a hydraulic climbing formwork system. Specifically, the hydraulic climbing formwork system is fixed to the already poured concrete wall via wall-attachment devices, and uses hydraulic cylinders as a power source to drive the formwork system to climb up the wall layer by layer.

[0003] With the development of industrialized construction, integrated climbing formwork platforms (commonly known as "building machines") have become core equipment for the construction of core tubes in super high-rise buildings. Building machines possess multiple functions, including overall lifting, integrated work platforms, formwork systems, and concrete placement. To further improve construction efficiency, an attempt was made to integrate the shaft formwork to the bottom of the building machine, allowing the machine to simultaneously carry the shaft formwork during the overall lifting process, thus saving the need for independently arranging traditional hydraulic climbing formwork inside the shaft. Summary of the Invention

[0004] The technical problem to be solved by this invention is to integrate the shaft template onto the building construction machine so that the shaft template can climb upward with the building construction machine.

[0005] This invention provides the following technical solution: an integrated formwork lifting device for a building construction machine, comprising a main platform of the building construction machine and a shaft formwork system; the main platform of the building construction machine includes a platform steel truss system and a lifting system connected to the bottom of the platform steel truss system and capable of attaching to the constructed structure; The shaft formwork system is connected to the bottom of the platform steel truss system via a decoupling suspension mechanism. The decoupling suspension mechanism includes an upper connecting frame, a lower connecting frame, and a hydraulic pin device. The upper connecting frame is fixedly connected to the platform steel truss system, and the lower connecting frame is fixedly connected to the shaft formwork system. The horizontal support hooks at the top of the lower connecting frame are suspended from the upper connecting frame, and the horizontal support hooks are in rolling contact with the upper connecting frame via ball bearings. Springs are distributed around the lower connecting frame and between it and the upper connecting frame. The surrounding springs horizontally support the lower connecting frame, allowing it to float when the shaft formwork system is demolded. The hydraulic pin device, supported by the upper connecting frame, can lock with the limiting hole on the lower connecting frame, and is used to lock the lower connecting frame when the shaft formwork system is being erected or when it is being lifted with the main platform of the building construction machine.

[0006] Furthermore, the upper connecting frame has a downward-opening window, and a support groove is arranged around the window, with a flat bottom; the lower connecting frame extends into the window, and a floating gap is reserved between it and the edge of the window; the ball bearings on the cross brace hook rest on the bottom surface of the support groove.

[0007] Furthermore, the shaft formwork system includes a top plate and two side molds. The bottom of the top plate is fixed with two left and right formwork supports. The two side molds are located outside the two formwork supports respectively. The side molds are connected to the corresponding formwork supports through a sliding guide mechanism. A demolding mechanism is connected between the two side molds. The demolding mechanism drives the two side molds to move closer or further away under the guidance of their respective sliding guide mechanisms.

[0008] Furthermore, the demolding mechanism includes a double-acting lead screw, guide rods, a drive motor, and a push-pull frame; the double-acting lead screw is centrally located, and the guide rods are symmetrically distributed on both sides of the double-acting lead screw and installed on the bottom surface of the top plate; a driven bevel gear is provided between the two threaded sections of the double-acting lead screw, and the drive motor is installed on the bottom surface of the top plate, with the driving bevel gear on the drive motor meshing with the driven bevel gear; each of the two threaded sections of the double-acting lead screw is threaded with a nut; the guide hole on the push-pull frame is slidably engaged with the guide rod, and the push-pull frame is fixedly connected to the nut; the push-pull frame is connected to the side mold for driving the side mold to move.

[0009] Furthermore, the shaft formwork system also includes a vibration mechanism, which includes a rotating shaft located between the side formwork and the push-pull frame. The bearing seat on the rotating shaft is connected to the bottom surface of the top plate, and a spherical hammer is connected to the rotating shaft via a flexible shaft. A force-bearing frame is fixed on the back of the side mold, and a push-pull bracket is inserted into the force-bearing groove of the force-bearing frame, with a reserved movable gap between the push-pull bracket and the force-bearing groove.

[0010] Furthermore, a first branch bevel gear is connected to the rotating shaft, and a second branch bevel gear is connected to the outside of the threaded section of the double-ended screw, with the first branch bevel gear meshing with the second branch bevel gear.

[0011] Furthermore, the spherical hammers are arranged in layers along the axis of rotation, with each layer containing n spherical hammers in a circular array, where n is an integer greater than 1.

[0012] Furthermore, a sliding rod is vertically fixed to the back of the side mold, and the sliding rod is slidably inserted into the guide hole of the template support to form a sliding guide mechanism.

[0013] Furthermore, the spring supports are located between the lower connecting frame and the sidewall of the support groove.

[0014] Furthermore, the pin end of the hydraulic pin device is chamfered around its entire circumference.

[0015] Compared with the prior art, the advantages of the present invention are: This invention provides an integrated formwork lifting device for a building construction machine, which enables the coordinated climbing of the shaft formwork system and the main platform of the building construction machine, significantly improving construction efficiency. By using a decoupled hanging mechanism, the shaft formwork system is directly connected to the bottom of the platform steel truss system of the main platform of the building construction machine, allowing the shaft formwork system to be lifted upwards along with the main platform, eliminating the need for a separate traditional hydraulic climbing formwork system within the shaft.

[0016] In the decoupled suspension mechanism, the lower connecting frame is suspended from the upper connecting frame via horizontal brace hooks, and a horizontally positioned spring connects the two. During demolding, the hydraulic pin device unlocks, allowing the lower connecting frame and the shaft formwork system fixed to it to float slightly under the support of the springs. This flexible connection allows the shaft formwork system to fine-tune its position during demolding, effectively releasing the adhesion and friction between the formwork and the concrete; and preventing the shaking of the shaft formwork system during demolding from being transmitted upwards to the platform steel truss system. When the shaft formwork system is lifted with the main platform of the building machine, the hydraulic pin device locks, and the shaft formwork system and the main platform of the building machine are rigidly connected as a whole. In this state, there is no relative degree of freedom of movement between the two, enabling them to jointly bear and transmit various loads generated during the lifting process, ensuring that the shaft formwork system can be lifted accurately and stably synchronously with the main platform of the building machine.

[0017] The shaft formwork system integrates a demolding mechanism consisting of a bidirectional lead screw, guide rod, and drive motor. This mechanism automatically and synchronously moves the two side formwork panels closer or further apart, achieving mechanized mold closing and demolding. Furthermore, a vibration mechanism linked to the demolding mechanism is designed. During demolding, the rotating shaft drives a ball hammer to rotate, intermittently striking the back of the side formwork to generate high-frequency vibration. This vibration removes any adhering concrete blocks from the side formwork, maintaining a smooth surface. Attached Figure Description

Detailed Implementation

[0020] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0021] like Figure 1 As shown: A building construction machine integrated formwork lifting device includes a building construction machine main platform and a shaft formwork system 4; the building construction machine main platform includes a platform steel truss system 1 and a lifting system 2 connected to the bottom of the platform steel truss system 1 and capable of being attached to the constructed structure 3; the lifting system 2 is installed on the outer wall of the constructed structure 3 through a wall-mounted structure, and the lifting system 2 achieves layer-by-layer climbing through a hydraulic mechanism. The above is the basic working principle of the existing building construction machine.

[0022] like Figures 2-7As shown: The improvement of this embodiment is that the shaft formwork system 4 is connected to the bottom of the platform steel truss system 1 through a decoupling suspension mechanism 5; the decoupling suspension mechanism 5 includes an upper connecting frame 5.1, a lower connecting frame 5.2 and a hydraulic pin device 5.3; the upper connecting frame 5.1 is fixedly connected to the platform steel truss system 1, and the top of the upper connecting frame 5.1 is fixedly connected to the bottom of the platform steel truss system 1 by bolts; the lower connecting frame 5.2 is fixedly connected to the shaft formwork system 4. The horizontal support hook 5.2.1 at the top of the lower connecting frame 5.2 is suspended on the upper connecting frame 5.1, and the horizontal support hook 5.2.1 makes rolling contact with the upper connecting frame 5.1 through ball bearings 5.2.2. The ball bearings 5.2.2 are nested in the ball socket at the end of the horizontal support hook 5.2.1, and the sliding friction is converted into rolling friction through the ball bearings 5.2.2, reducing the moving resistance of the horizontal support hook 5.2.1. Springs 5.4 are distributed around the lower connecting frame 5.2 and between it and the upper connecting frame 5.1. The surrounding springs 5.4 horizontally support the lower connecting frame 5.2, allowing the lower connecting frame 5.2 to float when the shaft formwork system 4 is demolded. The hydraulic pin device 5.3, supported by the upper connecting frame 5.1, can lock with the limiting hole 5.2.3 on the lower connecting frame 5.2, and is used to lock the lower connecting frame 5.2 when the shaft formwork system 4 is erected or when it is lifted with the main platform of the building machine.

[0023] The upper connecting frame 5.1 has a downward-opening window 5.1.1, and a support groove 5.1.2 is arranged around the window 5.1.1. The bottom of the support groove 5.1.2 is flat. The lower connecting frame 5.2 extends into the window 5.1.1, and a floating gap is reserved between the lower connecting frame 5.2 and the edge of the window 5.1.1. This floating gap allows the lower connecting frame 5.2 to move laterally within the window 5.1.1. The ball bearing 5.2.2 on the cross brace hook 5.2.1 rests on the bottom surface of the support groove 5.1.2. The protruding edge of the support groove 5.1.2 blocks the ball bearing 5.2.2 to prevent the ball bearing 5.2.2 from falling out of the support groove 5.1.2.

[0024] Specifically, the upper connecting frame 5.1 is a frame structure composed of an upper connecting plate, four hanging columns, and a lower connecting plate; from Figure 3 It can be determined that the upper connecting plate is connected to the platform steel truss system 1, and the lower connecting plate is connected to the lower connecting frame 5.2; the four hanging columns are located at the four corners of the upper and lower connecting plates. The hanging columns separate the upper and lower connecting plates, forming the installation space for the hydraulic pin device 5.3. The hydraulic cylinder of the hydraulic pin device 5.3 is fixed to the upper connecting plate, and the end of the hydraulic rod of the hydraulic pin device 5.3 is fitted with a pin.

[0025] like Figure 4 , Figure 5As shown: Window 5.1.1 and support groove 5.1.2 are both structures on the lower connecting plate of the upper connecting frame 5.1; window 5.1.1 is a rectangular opening, and support groove 5.1.2 is a groove that encircles window 5.1.1. The lower connecting frame 5.2 includes four connecting rods, each connected to a cross brace hook 5.2.1 at its top, and the tops of the four connecting rods are connected together by ribs. There are four springs 5.4, located at the midpoints of the four sides of window 5.1.1, supported between the ribs of the lower connecting frame 5.2 and the sidewalls of support groove 5.1.2; the four springs 5.4 apply the same elastic support force to the lower connecting frame 5.2 from the front, back, left, and right directions, keeping the lower connecting frame 5.2 centered within window 5.1.1. When the shaft template system 4 at the bottom of the lower connecting frame 5.2 shakes during demolding, the floating connecting frame 5.2 moves along with it, rather than suppressing the shaking of the shaft template system 4 during demolding. After demolding is complete and the shaft template system 4 comes to rest, the lower connecting frame 5.2 returns to its original position under the uniform elastic support force of the four springs 5.4.

[0026] It should be noted that the connection between the upper connecting frame 5.1 and the lower connecting frame 5.2 is not limited to four springs 5.4; this embodiment uses four springs 5.4 as an example for the convenience of those skilled in the art to understand; the elastic support force of the springs 5.4 around the lower connecting frame 5.2 just needs to be balanced.

[0027] When the hoistway formwork system 4 is erected or raised with the main platform of the building construction machine, to prevent uncontrolled swaying of the hoistway formwork system 4, the lower connecting frame 5.2 is locked by a hydraulic pin device 5.3, so that the hoistway formwork system 4, the lower connecting frame 5.2, and the main platform of the building construction machine are connected as a rigid whole. Figure 3 As shown: The limiting hole 5.2.3 on the lower connecting bracket 5.2 is a rectangular hole; as Figure 4 As shown: The pin of the hydraulic pin device 5.3 is a rectangular block that fits into it; the rectangular block is inserted into the rectangular hole, which can restrict the movement of the lower connecting frame 5.2 in the front, back, left, and right, and also restrict the torsion of the lower connecting frame 5.2. The end of the pin of the hydraulic pin device 5.3 is chamfered around its entire circumference to facilitate smooth insertion into the limiting hole 5.2.3.

[0028] like Figure 8 , Figure 9As shown: The shaft formwork system 4 includes a top plate 4.1 and two side forms 4.2. Two formwork supports 4.3 are fixed to the bottom of the top plate 4.1. The two side forms 4.2 are located outside the two formwork supports 4.3, respectively, and are connected to their corresponding formwork supports 4.3 via a sliding guide mechanism. A demolding mechanism connects the two side forms 4.2, which moves them closer or further apart under the guidance of their respective sliding guide mechanisms. When installing the formwork in the construction shaft, the demolding mechanism pushes the two side forms 4.2 outwards, ensuring their lower parts are flush against the constructed shaft wall, preparing for concrete pouring. After the concrete has cured, the demolding mechanism pulls the two side forms 4.2 inwards, separating them from the concrete.

[0029] A sliding rod 4.2.1 is vertically fixed to the back of the side mold 4.2. The sliding rod 4.2.1 is slidably inserted into the guide hole of the template support 4.3 to form a sliding guide mechanism, which guides the side mold 4.2 to only move closer to or away from the template support 4.3 in the horizontal direction.

[0030] The bottom of the two formwork supports 4.3 is connected to the base plate 4.17, which forms a platform for workers to enter the shaft formwork system 4 for inspection or manual adjustment of the formwork.

[0031] like Figure 9 , Figure 10 As shown: The demolding mechanism includes a bidirectional lead screw 4.4, guide rods 4.5, a drive motor 4.6, and a push-pull frame 4.7. The bidirectional lead screw 4.4 is centered, and the guide rods 4.5 are symmetrically distributed on both sides of the bidirectional lead screw 4.4 and installed on the bottom surface of the top plate 4.1. The two ends of the bidirectional lead screw 4.4 are supported by rotating seats, and the two guide rods 4.5 are parallel to the bidirectional lead screw 4.4. The bidirectional lead screw 4.4 has two sections of threads with opposite directions of rotation. A driven bevel gear 4.8 is set in the middle of the two sections of threads of the bidirectional lead screw 4.4. The drive motor 4.6 is installed on the bottom surface of the top plate 4.1, and the driving bevel gear 4.9 on the drive motor 4.6 meshes with the driven bevel gear 4.8. Nuts 4.10 are threadedly connected to the two sections of threads of the bidirectional lead screw 4.4. The guide hole on the push-pull frame 4.7 is slidably engaged with the guide rod 4.5, and the push-pull frame 4.7 is fixedly connected to the nut 4.10. The push-pull frame 4.7 is connected to the side mold 4.2 to drive the side mold 4.2 to move.

[0032] During operation, the drive motor 4.6 drives the double-ended lead screw 4.4 to rotate via a bevel gear pair. Because the two threads are in opposite directions, the two nuts 4.10 will cause their respective push-pull brackets 4.7 to move synchronously closer or further apart. The two push-pull brackets 4.7, along with the two side molds 4.2, move closer or further apart.

[0033] The shaft template system 4 also includes a vibration mechanism, which includes a rotating shaft 4.11 located between the side mold 4.2 and the push-pull frame 4.7. The bearing seat 4.12 on the rotating shaft 4.11 is connected to the bottom surface of the top plate 4.1. The bottom of the rotating shaft 4.11 is rotatably inserted into the bottom plate 4.17. A spherical hammer 4.13 is connected to the rotating shaft 4.11 via a flexible shaft. The flexible shaft is a rubber rod or a steel wire rope. The spherical hammer 4.13 is also a rubber hammer to avoid damaging the side mold 4.2. The spherical hammers 4.13 are arranged in layers along the axial direction of the rotating shaft 4.11, with n spherical hammers 4.13 in each layer arranged in a circular array, where n is an integer greater than 1. In this embodiment, n equals 3.

[0034] like Figure 11 As shown: The power of this vibration mechanism comes from the double-ended lead screw 4.4. A first branch bevel gear 4.15 is connected to the rotating shaft 4.11, and a second branch bevel gear 4.16 is connected to the outer side of the threaded section of the double-ended lead screw 4.4. The first branch bevel gear 4.15 and the second branch bevel gear 4.16 mesh. When the double-ended lead screw 4.4 rotates, the power is transmitted to the rotating shaft 4.11 through this pair of branch bevel gears, causing the rotating shaft 4.11 to rotate. The rotating shaft 4.11 swings the spherical hammer 4.13 through a flexible shaft, causing the spherical hammer 4.13 to strike the back of the side mold 4.2. The striking vibration effectively breaks the microscopic adhesion and capillary suction formed between the mold and the hardened concrete, allowing the mold to easily detach.

[0035] The lower end of the push-pull bracket 4.7 is connected to the load-bearing frame 4.14 on the back of the side mold 4.2. For example... Figure 9 As shown, the support frame 4.14 has a U-shaped or rectangular support groove. The end of the push-pull frame 4.7 is inserted into this support groove, and a certain amount of clearance is reserved between the two. When the ball hammer 4.13 strikes the side mold 4.2, the side mold 4.2 is allowed to vibrate. When the mold is supported, the push-pull frame 4.7 pushes out the side mold 4.2. The back of the side mold 4.2 is supported by the push-pull frame 4.7, and the forming surface (lower part) of the side mold 4.2 rests against the constructed shaft wall. The position of the side mold 4.2 is fixed.

[0036] The construction operation process is briefly described as follows: (a) Formwork status: The hydraulic pin device 5.3 is in the locked state, and the lower connecting frame 5.2 is rigidly connected to the upper connecting frame 5.1. The drive motor 4.6 of the demolding mechanism drives the bidirectional lead screw 4.4 to rotate, causing the two push-pull frames 4.7 to push the side formwork 4.2 outward, so that its lower part is tightly attached to the constructed well wall, ready for concrete pouring.

[0037] (II) Demolding State: After the concrete curing is completed, the hydraulic pin device 5.3 first retracts the pin, allowing the lower connecting frame 5.2 to return to its floating state. Then, the drive motor 4.6 is started and reversed, driving the push-pull frame 4.7 to pull the side formwork 4.2 inward. During demolding, the lower connecting frame 5.2 sways together with the shaft formwork system 4. At the same time, the branch bevel gear pair drives the rotating shaft 4.11 to rotate, and the ball hammer 4.13 strikes the back of the side formwork 4.2, generating high-frequency vibration to remove the concrete blocks adhering to the side formwork 4.2.

[0038] (III) Overall Lifting Status: After demolding is completed, the hydraulic pin device 5.3 locks again, fixing the shaft formwork system 4 and the main platform of the building machine into a whole. Subsequently, the lifting system 2 of the building machine is activated, pushing the entire device (including the platform steel truss system 1 and the shaft formwork system 4 suspended below it) to climb up to the next construction floor.

[0039] (iv) Re-formwork: After reaching the new floor, repeat step one to prepare for the next cycle of concrete pouring.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
