Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction template removal device for construction engineering. Background Art

[0002] Building formwork, also known as formwork engineering, is a supporting structure used to form the shape and surface of building components when pouring concrete in construction. It is a temporary structure used to support the hardening and curing of concrete during the construction process to ensure that the final component has the desired shape, size and surface quality. Building formwork used in construction projects is generally removed using a crowbar.

[0003] For example, a crowbar disclosed in the authorization announcement number CN208440252U includes a stick body and a lifting support connected to the front end face of the stick body, and the lifting support includes a wedge-shaped insertion portion and a receiving portion connected between the insertion portion and the front end face of the stick body, and the receiving portion is in the shape of a flat plate. After adopting the above technical scheme, the beneficial effects of the utility model are as follows: when the insertion portion is inserted under the bottom surface of the object to be moved and the object to be moved is pried up, the bottom surface of the object to be moved can be moved to the receiving portion and then received by the receiving portion. The contact area between the receiving portion and the bottom surface of the object to be moved is large, and the pressure is small, which can prevent the bottom surface of the object to be moved from being crushed. Even if shaking occurs during the prying process and causes the rotation between the crowbar and the object to be moved, the bottom surface of the object to be moved will not be scratched.

[0004] The above device has a simple structure and reasonable design, can meet the needs of users, and has great promotion value;

[0005] However, the above patent has the following shortcomings:

[0006] Although the above-mentioned crowbar will not scratch the bottom surface of the object being moved when in use, when the building formwork is pried, the formwork will tilt toward one side of the worker, and injure the worker without the support of others. Utility Model Content

[0027] A construction formwork removal device for construction engineering, comprising a slide 1, a storage box 2 is arranged at the top of the slide 1, a first folding plate 3 and a second folding plate 4 are movably mounted at both ends of the storage box 2, and the first folding plate 3 and the second folding plate 4 are movably connected on the same side by a rotating shaft; a telescopic mechanism 5 is arranged inside the slide 1, and the telescopic mechanism 5 comprises a first screw rod 501, a sleeve 502 and a side strip 503, and a crowbar 6 is fixedly connected to the end of the sleeve 502 away from the first screw rod 501, and the bottom of the first folding plate 3 and the second folding plate 4 are movably mounted. A folding mechanism 7 is provided at the end, and the folding mechanism 7 includes a first pulley 701, a second pulley 702 and a belt 703; a guide sleeve 8 is fixedly installed on the side of the slide 1 away from the crowbar 6, and the end of the first screw rod 501 away from the sleeve 502 passes through the guide sleeve 8 and is fixedly connected to a handle 9, and both sides of the handle 9 are fixedly connected to anti-skid jackets 10; the sleeve 502 is movably installed outside the first screw rod 501, and the outer walls of both sides of the sleeve 502 are fixedly connected to the side strips 503, and the inner sides of the slide 1 are provided with strip grooves matching the side strips 503;

[0028] In this embodiment, when working, the grip handle 9 is rotated, and the rotation of the handle 9 drives the first screw rod 501 to rotate synchronously. The rotation of the first screw rod 501 drives the sleeve 502 to move. When the sleeve 502 moves, it is guided by the sliding of the side strips 503 on both sides and the strip grooves, thereby controlling the sleeve 502 to extend from the end of the slide 1 along a straight line, and then drives the crowbar 6 to move forward. After use, the sleeve 502 is put into the slide 1. In this way, the length is short when carried daily, and it does not take up space, which makes it easy to carry.

[0029] like Figure 2 and Figure 3 As shown, a second screw rod 11 is movably mounted on the inner bottom end of the storage box 2, and movable blocks 12 are movably mounted on both ends of the second screw rod 11. The top ends of the two movable blocks 12 are movably connected to the first folding plate 3 and the second folding plate 4 respectively through connecting members 13. The threads at both ends of the second screw rod 11 are opposite. The first pulley 701 is fixedly mounted on the outside of the end of the first screw rod 501 close to the guide sleeve 8, and the second pulley 702 is fixedly mounted on the outside of the end of the second screw rod 11 close to the first pulley 701.

[0030] In this embodiment, when the handle 9 drives the first screw rod 501 to rotate, one end of the first screw rod 501 drives the first pulley 701 to rotate. When the first pulley 701 rotates, the second pulley 702 at the same end of the second screw rod 11 is driven to rotate synchronously through the belt 703, and then the movable blocks 12 at both ends are driven to move toward the middle direction of the second screw rod 11 through the second screw rod 11. When the two movable blocks 12 move, the first folding plate 3 and the second folding plate 4 are folded into a triangular structure through the connecting member 13. In this way, when the building formwork is pried by the crowbar 6, the formwork is tilted and supported by the triangular structure, which can prevent the formwork from injuring workers.

[0031] Working principle: during operation, the handle 9 is held and rotated, and the handle 9 drives the first screw rod 501 to rotate synchronously after the rotation of the handle 9, and the sleeve 502 is driven to move after the first screw rod 501 rotates. When the sleeve 502 moves, it is guided by the side strips 503 on both sides and the strip grooves for sliding, and then the sleeve 502 is controlled to extend from the end of the slide 1 along a straight line, and then the crowbar 6 is driven to move forward, and the sleeve 502 is put into the slide 1 after use; when the handle 9 drives the first screw rod 501 to rotate, one end of the first screw rod 501 drives the first pulley 701 to rotate, and when the first pulley 701 rotates, the second pulley 702 at the same end of the second screw rod 11 is driven to rotate synchronously through the belt 703, and then the movable blocks 12 at both ends are driven to move toward the middle direction of the second screw rod 11 through the second screw rod 11. When the two movable blocks 12 move, the first folding plate 3 and the second folding plate 4 are folded through the connecting member 13 to form a triangular structure. In this way, when the building template is pried by the crowbar 6, the template is supported by the triangular structure after tilting.
