Description

Technical Field

[0001] The utility model relates to the technical field of on-site concrete pouring construction in civil engineering, and specifically, to a concrete form removal tool. Background Art

[0002] Concrete has good durability, moldability, and high compressive strength, and is widely used. In the process of concrete construction, a major task is formwork erection and removal, which directly affects the quality of concrete construction.

[0003] Among them, the existing form removal methods are all manual form removal. The traditional manual form removal technology mainly relies on workers using tools such as crowbars and hammers for removal. However, since some forms are strongly bonded to the concrete, the removal difficulty is usually high. Although this method is simple and direct, it has many disadvantages.

[0004] First of all, manual form removal is inefficient and labor-intensive, which is not conducive to improving construction efficiency; secondly, during manual form removal, it is easy to damage the concrete structure, affecting the quality and aesthetics of the structure; finally, the safety of manual form removal is relatively low, and it is easy to cause accidents of workers being injured. Summary of the Utility Model

[0005] The purpose of the utility model is to address the deficiencies of the existing technology, and thus provide a concrete form removal tool with a significantly improved form removal efficiency, a reduced damage rate of the concrete structure, and higher safety.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a concrete form removal tool, comprising a vehicle frame, a power control component, a support component, a driving motor, a traction chain, a traction head, a lifting chain, and a form fixator;

[0007] The vehicle frame is a movable vehicle frame with a self-locking structure;

[0008] The driving motor is installed on the vehicle frame, and the power control component is installed on the vehicle frame and used to control the working state of the driving motor;

[0009] The driving end of the driving motor is connected to the traction chain, the distal end of the traction chain is installed with the traction head, the traction head is connected to a plurality of lifting chains, the ends of the lifting chains are connected to the form fixator, and the form fixator is used to fix to the back of the concrete form;

[0010] The support component is foldably installed on the vehicle frame and used to provide a supporting force between the vehicle frame and the plane where the concrete form is located;

[0011] In the removal state, each of the lifting chains is radially distributed with the traction head as the center.

[0012] Preferably, the type of the driving motor is a lifting motor or a hoisting motor, and the proximal end of the traction chain is wound around the driving end of the lifting motor or the hoisting motor to provide traction force.

[0013] Preferably, a housing is arranged outside the vehicle frame, the power control assembly and the driving motor are installed in the housing, a part of the traction chain is located inside the housing, and an opening for passing the traction chain is formed at one end of the housing.

[0014] Preferably, the vehicle frame is a vertical vehicle frame with a height greater than its length.

[0015] Preferably, the traction head is a hook or a hanging ring.

[0016] Preferably, the drum of the lifting motor or the hoisting motor is arranged based on the vehicle frame, and the center of the drum corresponds to the opening.

[0017] Preferably, a switch door is arranged at the opening.

[0018] Preferably, the formwork fixator is disc-shaped.

[0019] Preferably, the formwork fixator is a negative pressure disc type fixator or a bolt disc type fixator.

[0020] Preferably, universal wheels are installed at the bottom end of the vehicle frame.

[0021] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model adopts the design concept of mechanization and automation, can quickly and accurately position and remove the formwork, and reduces the damage to the finished concrete caused by the traditional manual violent removal with crowbars and the like.

[0022] Specifically, by using the formwork fixator and the traction method, the force is dispersed at each point of the formwork, and the force is more balanced. Then, the lifting motor is used to pull the hoisting part, thereby completing the removal work of the concrete formwork.

[0023] When the shapes and materials of the formworks are different, the specified positions of the formwork fixators can be flexibly determined, or different formwork fixators can be used to fix them and pull them for removal.

[0024] The operation and use of the whole device are simple. It can be operated by a single person and does not require other auxiliary equipment. Only by tightening the nuts, the process can be completed. It can also be applicable to formworks of different block sizes. When the module area increases, only the length of the lifting and fixing support frame needs to be increased. Description of the Drawings
