Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to a building template removal device. Background Art

[0002] Building formwork is a temporary support structure, manufactured according to design requirements, that helps concrete structures and components form to the specified positions and dimensions, maintain their correct position, and withstand the formwork's own weight and external loads. The purpose of formwork engineering is to ensure concrete quality and construction safety, accelerate construction progress, and reduce project costs. The formwork itself is not retained on the building. To maximize formwork utilization and reduce project costs, existing formwork structures require repeated installation and disassembly to increase the number of formwork turnovers.

[0003] Publication number CN111550046B discloses a formwork prying bar that addresses the issues of workers being injured by prying off the formwork and the considerable effort required to hold the formwork with an auxiliary crowbar to pry it off. The bar comprises a movable pry bar movably connected to a first handlebar, with square bars rotatably connected to both sides of the first handlebar. Linked pry bars are slidably mounted on the outer ends of the square bars, and a steel wire rope is hooked to one end of the linked pry bar. When the first handlebar is held and the movable pry bar is pressed upward or downward, the formwork is pried by a flat pry block, which drives the drive gear to rotate, causing the driven gear to rotate synchronously in the opposite direction under the meshing of the drive gear, driving the square bars to rotate in the opposite direction, causing the linked pry bar to move synchronously and in opposite directions with the movable pry bar, assisting the flat pry block in prying off the entire formwork.

[0004] Although the above technical solution can avoid the problem of injuring workers when the formwork is pried off and the need to hold the formwork with an auxiliary crowbar to pry off the formwork when prying off the formwork, since the formwork is tightly fitted to the wall, workers still need to use a lot of force to press down the crowbar to loosen the formwork and remove the formwork. In addition, during the removal process, the crowbar is against the wall surface, which can easily cause damage to the wall. Moreover, the initial angle between the crowbar and the hand-held rod remains constant, which is not convenient for removing formwork with different inclination angles.

[0005] Therefore, it is necessary to invent a construction template removal device to solve the above problems. Summary of the Invention

[0037] The prying assembly 5 is arranged at both ends of the left side of the installation cylinder 31, and includes a prying rod 51, which is used to pry up the template.

[0038] Specifically, the pry bar 51 is divided into two parts, including a pad 511 and a pry plate 512. The pad 511 is fixedly set on the left side of the installation cylinder 31. A clearance groove is opened on the left side of the installation cylinder 31. The pry plate 512 is rotatably set below the pad 511, and the right end of the pry plate 512 passes through the clearance groove to the interior of the adjustment cylinder 3. The pad 511 fits against the wall to protect the wall. The pry plate 512 contacts the template and pries up the template when rotating.

[0039] At the same time, the prying assembly 5 also includes: a bracket 52, which is fixedly arranged inside the mounting cylinder 31; a driven half gear 53, which is rotatably arranged inside the bracket 52, and the right end of the prying plate 512 is fixedly connected to the driven half gear 53; a reversing gear 54, which is rotatably arranged inside the bracket 52 and meshes with the driven half gear 53, and the reversing gear 54 is located on the right side of the driven half gear 53; a driving half gear 55, which is fixedly arranged on the driving shaft 61 and can intermittently mesh with the reversing gear 54, and the driving half gear 55 is located on the right side of the reversing gear 54; a return torsion spring 56, which is fixedly arranged on both sides of the bracket 52, and the two ends of the return torsion spring 56 are respectively engaged with the central axis of the driven half gear 53 and the bracket 52, and the return torsion spring 56 can provide torsion to the driven half gear 53, so that when the driven half gear 53 is not subjected to other forces, the prying plate 512 automatically rotates upward and fits against the bottom of the pad 511.

[0040] The driving system 6 is in transmission connection with the impact assembly 4 and the prying assembly 5 .

[0041] Specifically, the drive system 6 includes a drive shaft 61, which is rotatably arranged inside the adjustment cylinder 3; a drive motor 62, which is fixedly arranged at the bottom of the hand-held rod 1, and the drive motor 62 can be connected to an external power supply or a battery. This is the existing technology and will not be repeated here; a transmission shaft 63, which is coaxially rotatably arranged inside the hand-held rod 1, and the bottom end of the transmission shaft 63 is fixedly connected to the output shaft of the drive motor 62, and the top end of the transmission shaft 63 passes through the interior of the adjustment cylinder 3; a transmission gear set 64, which is transmitted between the transmission shaft 63 and the drive shaft 61, and the drive motor 62 can drive the drive shaft 61 to rotate through the transmission shaft 63 and the transmission gear set 64, so that the drive shaft 61 drives the impact assembly 4 and the prying assembly 5 to move.

[0042] The limiting mechanism 7 is provided between the adjusting seat 2 and the turning cylinder 32 and is used for adjusting and limiting the angle of the adjusting cylinder 3 .

[0043] Specifically, the limiting mechanism 7 includes two guide rails 71 symmetrically disposed on the right bottom side of the flip cylinder 32. The spacing between the two guide rails 71 is consistent with the thickness of the adjustment base 2 in the front-to-back direction. The two guide rails 71 fit the front and rear sides of the adjustment base 2, which can effectively improve the connection stability between the adjustment cylinder 3 and the adjustment base 2; two guide posts 72 symmetrically disposed on the front and rear sides of the flip cylinder 32. The two guide rails 71 are respectively sleeved on the outside of the corresponding side guide posts 72; a connecting ear 73 fixedly disposed on the guide rail 71; a plurality of positioning screw holes 74, each of which is provided on one side of the flip cylinder 32. The connecting ear 73 can be connected to the corresponding positioning screw hole 74 by a bolt to limit the position of the flip cylinder 32. By providing multiple positioning screw holes 74, the connecting ear 73 can be fixed to multiple different positions, thereby realizing multi-angle adjustment of the adjustment cylinder 3; and a through slot 75 provided at the bottom of the adjustment cylinder 3. The transmission shaft 63 extends into the interior of the adjustment cylinder 3 through the through slot 75.

[0044] The outside of the hand-held rod 1 is adjustable with a handle 8, and the handle 8 is provided with a switch for controlling the start and stop of the drive motor 62. Controlling the start and stop of the drive motor 62 by the switch is a prior art and will not be described here and is not shown in the figure.

[0045] In summary, when the present device is in use, the angle of the adjusting cylinder 3 is first adjusted according to the position of the template to be removed, so that the impact rod 41 and the pry bar 51 can be more easily aligned with the gap between the template and the wall. Specifically, first remove the bolt between the connecting ear 73 and the positioning screw hole 74 to release the limit between the adjusting seat 2 and the adjusting cylinder 3, rotate the adjusting cylinder 3, and slide the guide rail 71 and the guide column 72 relative to each other. When the adjusting cylinder 3 is adjusted to the appropriate angle, that is, after the impact rod 41 and the pry bar 51 are adjusted to the appropriate angle, fix the connecting ear 73 to the corresponding positioning screw hole 74 by bolts to complete the angle adjustment of the adjusting cylinder 3.

[0046] It should be noted that since the drive shaft 61 and the transmission shaft 63 are connected through the transmission gear set 64, during the rotation of the adjustment cylinder 3, the drive shaft 61 and the transmission shaft 63 can always maintain an engaged state, and the through groove 75 will not interfere with the transmission shaft 63.

[0047] Then the user holds the hand-held rod 1 with one hand and the handle 8 with the other hand, stands the device upright, aligns the impact rod 41 with the left end of the pry bar 51 and inserts them into the gap between the template and the wall, starts the drive motor 62, and the drive motor 62 drives the drive shaft 61 to rotate through the transmission shaft 63 and the transmission gear set 64. The drive shaft 61 drives the cam 47 and the drive half gear 55 to rotate synchronously. During the process of the drive shaft 61 rotating one circle, on the one hand, the driving half gear 55 first meshes with the reversing gear 54, and drives the driven half gear 53 to rotate through the reversing gear 54. The driven half gear 53 drives the pry plate 512 to rotate, so that the left end of the pry plate 512 rotates away from the pad 511, thereby prying the template. As the driving half gear 55 continues to rotate, it will disengage from the reversing gear 54. The driving half gear 55 is no longer meshed with the reversing gear 54. The driven half gear 53 will rotate under the torsion of the return torsion spring 56, so that the pry plate 512 moves closer to the pad When the driving shaft 61 rotates one circle, the multiple protrusions on the cam 47 push the supporting frame 46 in turn, that is, during the process of the driving shaft 61 rotating one circle, the prying plate 512 pries up the template once; on the other hand, while the prying plate 512 is prying and resetting, the multiple protrusions of the cam 47 can push the supporting frame 46 multiple times. When one protrusion of the cam 47 contacts the supporting frame 46, it will push the supporting frame 46 to move left, and the supporting frame 46 pushes the impact rod 41 to move left through the connecting rod 45, so that the impact rod 41 impacts the gap between the template and the wall. When the protrusion disengages from the supporting frame 46, the elastic member 44 pushes the impact rod 41 to move right, so that the impact rod 41, the connecting rod 45 and the supporting frame 46 all return to their initial state to the right. During the process of the driving shaft 61 rotating one circle, the multiple protrusions on the cam 47 push the supporting frame 46 in turn, that is, during the process of the driving shaft 61 rotating one circle, the impact rod 41 impacts the gap between the template and the wall multiple times.

[0048] When the protrusion of the cam 47 contacts the support frame 46, the support frame 46 moves to the left, causing the impact rod 41 to impact to the left. When the protrusion of the cam 47 disengages from the support frame 46, the elastic member 44 pushes the impact rod 41 to move to the right, realizing the impact and reset of the impact rod 41. As the drive shaft 61 drives the cam 47 to rotate continuously, the impact rod 41 can quickly and repeatedly impact and vibrate the gap between the template and the wall, thereby effectively expanding the gap between the template and the wall, accelerating the loosening between the template and the wall, and facilitating the removal of the template.

[0049] When the driving half gear 55 is engaged with the reversing gear 54, the driven half gear 53 and the pry plate 512 are driven to rotate, so that the pry plate 512 rotates in the direction away from the pad 511, thereby prying the template. When the driving half gear 55 is disengaged from the reversing gear 54, the return torsion spring 56 drives the driven half gear 53 and the pry plate 512 to reset, and the pry plate 512 is restored to a state of being in contact with the pad 511. As the driving shaft 61 drives the driving half gear 55 to continue to rotate, the pry plate 512 can repeatedly pry the template, thereby separating the template from the wall and realizing the removal of the template. In addition, during the process of the pry plate 512 prying the template, since the pad 511 is located above the pry plate 512 and is always in contact with the wall, the pry plate 512 will not come into contact with the wall during the prying process, thereby avoiding damage to the wall and ensuring that the wall remains intact after the template is removed.

[0050] While the impact rod 41 repeatedly impacts the template and the wall, the pry plate 512 repeatedly pries up the template, so that the template can be quickly separated from the wall, thereby achieving rapid removal of the template and improving the efficiency of template removal work.

[0051] By removing the bolts between the connecting ear 73 and the positioning screw hole 74 and rotating the adjusting cylinder 3, the guide rail 71 and the guide column 72 can slide relative to each other. After the impact rod 41 and the pry bar 51 are adjusted to a suitable angle, the connecting ear 73 is fixed to the corresponding positioning screw hole 74 by bolts to complete the angle adjustment of the adjusting cylinder 3, so that the impact rod 41 and the pry bar 51 are at an angle that is easier to insert into the gap between the template and the wall, so that the device can remove templates with different inclination angles, thereby improving the applicability of the device.

[0052] By providing an impact rod 41 and pry bars 51 on both sides, the device can pry up multiple points of the template at the same time, without the user having to repeatedly pry up different points of the template, thereby achieving rapid removal of the template and improving work efficiency. Prying up multiple points at the same time can avoid the generation of concentrated stress, thereby avoiding damage to the template and preventing deformation of the template during the removal process.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
