Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction equipment, in particular to the technical field of mutual climbing type sliding formwork platforms. BACKGROUND

[0002] The current overall sliding formwork support frame mostly adopts a tray type steel frame to support steel pipe scaffolding or disc buckle frame, and after a bulldozer replaces the supporting wooden square or cushion block at the bottom of the frame, a winch is fixed to the ground to pull and slide. This construction method and sliding system have high requirements for site hardening and flatness, and more personnel intervention steps and operations are required. During the conversion from the formwork state to the sliding state, a jack needs to be used to jacking the formwork frame, and a bulldozer is used to replace the supporting cushion block at the bottom. The traction force is external, and there is a large deformation and uncontrollable risk for the frame and the formwork support frame. SUMMARY

[0003] The technical problem to be solved by the present application is to overcome the deficiencies in the prior art and provide a mutual climbing type sliding formwork platform to solve the problems of poor integration, low automation, high site requirements and complicated operation of traditional sliding formwork technology.

[0004] To achieve the above-mentioned purpose, the present application provides a mutual climbing type sliding formwork platform, which comprises a formwork steel platform, an adjustable support system and a sliding mechanism. The adjustable support system is connected to the bottom of the formwork steel platform and is used to jacking or lowering the formwork steel platform to convert between the supporting state and the sliding state. The sliding mechanism is used to drive the formwork steel platform to slide along a predetermined path. The sliding mechanism comprises a track beam and a driving assembly. The track beam is provided with a climbing gear along its length direction. The driving assembly comprises a double-acting hydraulic cylinder, a lower reversing box and an upper reversing box. The lower reversing box and the upper reversing box are both provided with a clamping tongue capable of selectively engaging with the climbing gear. The two ends of the double-acting hydraulic cylinder are respectively in transmission connection with the lower reversing box and the upper reversing box, and the upper reversing box is connected with the formwork steel platform. By controlling the extension and retraction of the double-acting hydraulic cylinder, the clamping tongues of the upper and lower reversing boxes are alternately engaged with and disengaged from the climbing gear to respectively realize the sliding of the formwork steel platform along the track beam and the forward movement of the track beam relative to the already positioned formwork steel platform.

[0005] As a preferred, the adjustable support system comprises a transverse bottom frame beam and a worm gear elevator. This preferred scheme provides a reliable and accurately adjustable support foundation for the platform by combining the stable bottom frame beam structure with the worm gear mechanism having self-locking characteristics.

[0006] Preferably, the worm gear jack has a load-bearing capacity of 50 to 100 tons and can achieve a vertical lifting and lowering stroke of not less than 100 mm. This preferred solution ensures that the support system can withstand large loads during construction and meets the needs of most engineering scenarios.

[0007] Preferably, the sliding mechanism further includes a longitudinal bottom frame beam, a sliding support roller assembly, and bidirectional limiting rollers. The sliding support roller assembly is installed at the bottom of the longitudinal bottom frame beam and is used to support the track beam during sliding. The bidirectional limiting rollers are installed on the longitudinal bottom frame beam and cooperate with the side of the track beam to limit horizontal displacement and prevent overturning. This preferred solution, through a dedicated load-bearing and guiding limiting structure, ensures the stability and directional accuracy of the platform during sliding.

[0008] Preferably, the bidirectional limiting roller includes a horizontal limiting roller bearing and an overturning limiting roller. This preferred solution constrains the platform in both horizontal and vertical dimensions, effectively preventing lateral displacement and overturning that may occur during sliding, thus enhancing safety.

[0009] Preferably, the sliding mechanism further includes a track beam pad placed under the track beam. This preferred solution adjusts the levelness of the track beam using the pad, adapting to uneven construction ground and reducing the requirements for the site foundation.

[0010] Preferably, the upper reversing box is connected to the formwork steel platform via a power connection seat. This preferred solution achieves effective power connection and transmission between the hydraulic drive assembly and the platform body, and allows for a certain degree of angle variation to adapt to working conditions.

[0011] The present invention also provides a construction method using the above-described interlocking sliding formwork platform, comprising the following steps: S1. State transition to sliding preparation: Operate the adjustable support system to lower the formwork steel platform, so that the sliding mechanism contacts and bears the load with the track beam, and then adjust the adjustable support system to lift it off the ground; S2, Platform Sliding: Control the drive assembly so that the double-acting hydraulic cylinder drives the latches of the upper and lower reversing boxes to advance along the track beam in a step-by-step meshing manner, thereby pushing the formwork steel platform to slide along the track beam to the target work position; S3, State transition to formwork in place: Operate the adjustable support system to support the ground and lift the formwork steel platform to complete the load transfer, and level the formwork steel platform to the construction elevation; S4. Track beam forward movement: With the formwork steel platform being lifted and supported, control the drive assembly to make the double-acting hydraulic cylinder drive the upper reversing box and the lower reversing box to act in opposite directions, pushing the track beam along its length to the next section position.

[0012] Preferably, in the step of transitioning to the formwork in place, after the formwork steel platform is lifted, the track beam is lifted off the ground by the overturning limiting rollers of the bidirectional limiting rollers. This preferred solution cleverly utilizes the existing structure to automatically lift the track beam, creating unobstructed conditions for the forward movement of the track beam and simplifying the operation.

[0013] The beneficial effects of this invention are: 1. This system combines a hydraulic automatic sliding system and an adjustable support system with the formwork platform to form an integrated, standardized, and automated sliding formwork platform product; 2. Because this system achieves the organic integration of various systems, without other scattered components or external driving forces, it can simply and efficiently realize the overall height adjustment, sliding and positioning support of the platform, saving manpower and time. Each step is clear, simple, efficient and fast. 3. The support system and sliding mechanism are highly standardized and have good versatility, enabling them to be reused in different projects.

[0014] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

The formwork steel platform 8 serves as the upper construction operating surface, designed and fabricated according to the actual span and load requirements on site. The adjustable support system is connected to the bottom of the formwork steel platform 8, used to achieve overall lifting and stable support during construction. It mainly includes a transverse bottom frame beam 1 and a worm gear lift 7 mounted on it. The sliding mechanism drives the formwork steel platform 8 to automatically slide along a preset track. It mainly includes a longitudinal bottom frame beam 2, a sliding support roller group 3, bidirectional limiting rollers 4, a track beam 5, a track beam pad 6, a double-acting hydraulic cylinder 9, a lower reversing box 10, an upper reversing box 11, and a power connection seat 12. Among them, the sliding support roller group 3 and the bidirectional limiting roller 4 are installed on the longitudinal bottom frame beam 2; the track beam 5 is provided with climbing teeth 5.1 at intervals; the upper reversing box 11 is hinged to the formwork steel platform 8 through the power connection seat 12; both the lower reversing box 10 and the upper reversing box 11 are provided with swingable latches, which can selectively engage with the climbing teeth 5.1; the two ends of the double-acting hydraulic cylinder 9 are respectively connected to the lower reversing box 10 and the upper reversing box 11.

[0018] Working process of this invention: The working process of the mutual climbing sliding support platform of the present invention is described in conjunction with the accompanying drawings.

[0019] The present invention relates to a mutual climbing sliding formwork support platform, comprising a formwork support steel platform 8, an adjustable support system, and a sliding mechanism, wherein the formwork support steel platform 8 is designed and manufactured according to the actual needs of the site.

[0020] The adjustable support system mainly consists of a transverse bottom frame beam 1 and a worm gear lift 7; The sliding mechanism comprises a longitudinal bottom frame beam 2, a sliding support roller assembly 3, bidirectional limiting rollers 4, a track beam 5, a track beam pad 6, a double-acting hydraulic cylinder 9, a lower reversing box 10, an upper reversing box 11, and a power connection seat 12. (See attached diagram) Figures 1-4 . The entire operation process of this invention corresponds to Figure 6 The flowchart shown below: Step 1 (corresponding to) Figure 6(First Working Condition): State Transition and Preparation for Sliding. After the beam and slab structure reaches the design strength, the formwork is removed from the support platform. The entire support platform and sliding mechanism are lowered by about 5cm by adjusting the worm gear lift 7, so that the track beam 5 lands on the track beam pad 6. The thickness of the pad is adjusted to eliminate ground elevation errors and make the track beam basically level. The platform continues to fall until the roller bearings on the sliding support roller group 3 land on the surface of the track beam 5, so that the weight of the platform is transferred to the track beam 5 through the support roller group 3. The length of the worm gear lift 7 is then retracted to lift it off the ground by a certain distance to avoid collision with ground obstacles during the platform sliding process. Step 2 (corresponding to) Figure 6 (Second Working Condition): The platform slides forward automatically. Check if the latches of the upper reversing box 11 and the lower reversing box 10 are in the correct direction. Activate the hydraulic control system to provide power to the double-acting hydraulic cylinder 9, driving the upper and lower reversing boxes 10 and 11 to slide forward alternately along the crawler teeth 5.1 on the track (this process is automatic sliding and requires no manual intervention). The upper reversing box, through its power connection seat 12 with the formwork platform, pushes the entire formwork platform and the sliding support roller assembly 3 forward along the track beam 5 until it reaches the designated position. During the sliding process, the horizontal limit roller bearing 4.1 and the overturning limit roller 4.2 of the bidirectional limit roller 4 restrict the platform's displacement in all directions, ensuring the platform slides along the track beam. Step 3 (corresponding to) Figure 6 (Third Working Condition): After the formwork platform slides into place, the worm gear lift 7 extends to make its supporting chassis contact the ground and fix the platform position, completing the force system conversion after sliding. The worm gear lift continues to extend to raise the height of the entire platform system, so that all the force of the formwork platform is transferred to the lift, and the track beam 5 is gradually lifted off the ground and the platform is leveled. After the platform is raised into place, the formwork frame and template are erected on the top of the platform, and the rebar binding and concrete pouring operations are carried out. Step 4 (corresponding to) Figure 6 (Fourth Working Condition): After the formwork platform is raised and positioned, the track beam 5 can be slid to prepare for the sliding of the next platform section. After the formwork platform is raised and positioned, it is raised by about 5cm. The track beam 5 is lifted off the ground by the overturning limiting roller 4.2 of the bidirectional limiting roller 4. In this state, the direction of the upper and lower reversing boxes is adjusted so that the reversing boxes enter the reverse working state and provide power to the double-acting hydraulic cylinder 9 to realize the reverse pushing process of step 2, and gradually and automatically push the track beam 5 to the next section.

[0021] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
