Description

Technical Field

[0001] The invention relates to the technical field of building templates, and in particular to a progressive wall building template removal device. Background Art

[0002] In order to efficiently and safely remove the building formwork from the wall, it is necessary to use formwork removal tools to gradually separate the formwork and reduce damage to the wall and the formwork itself.

[0003] Existing formwork removal tools are usually designed as crowbars with different characteristics at both ends. They use a steel bar with two ends bent into different angles for formwork removal. The large-angle end is a flat pry bar, which is usually used in situations where a large lever force is required. It is easier to wedge into narrow or hard-to-reach spaces, such as the gap between the formwork and concrete, the joints between ground bricks, etc., so that workers can complete the removal task more easily; the small-angle end is a hook pry bar, which is more suitable for fine adjustments or entering smaller spaces to work, providing higher precision and control, for example, by hooking the edge or hole of the formwork, or partially pulling the raised structure of the formwork (such as bolts, locating pins), so as to avoid damaging the surrounding structures or materials that do not need to be removed during the removal process. In addition, in order to meet different formwork removal needs, such tools will be made in a variety of lengths so that longer tools can be used when removing formwork at higher positions.

[0004] However, in a construction site environment, due to the complex and changeable scenes, the longer poles are extremely inconvenient to rotate and operate, and are prone to interfere with other upright poles. Frequent rotation and switching of the two ends of the crowbar not only affects work efficiency, but also places a heavy physical burden on construction workers. Summary of the invention

[0005] In order to overcome the technical shortcomings of the existing crowbars, the present invention provides a progressive wall building template removal device.

[0006] A progressive wall building formwork removal device comprises a main pipe, the bottom of the main pipe is threadedly connected with at least one connecting pipe, the top of the main pipe is rotatably connected with a tilting rod head, the side of the main pipe close to the tilting rod head is rotatably connected with a gear, the tilting rod head is meshed with the gear, a push rod is slidably connected in the main pipe, the side of the main pipe close to the gear is slidably connected with a guide frame for pushing and pulling the gear for forward and reverse rotation, one end of the push rod is in contact with the guide frame, a spring is fixedly connected between the main pipe and the guide frame, a sliding rod is slidably connected in the connecting pipe, the other end of the push rod is in contact with an adjacent sliding rod, the sliding rod is fixedly connected with a card block symmetrically distributed along the sliding rod, the connecting pipe is slidably connected with a card frame, the side of the card frame close to the adjacent card block is set as an inclined surface, the inclined surface of the card frame is squeezed and matched with the adjacent card block, and a tension spring is fixedly connected between the card frame and the adjacent connecting pipe.

[0007] Optionally, an external thread groove is formed on the upper portion of the connecting pipe, and an internal thread groove is formed on the lower portion of the connecting pipe.

[0008] Optionally, a movable groove is formed on a side of the guide frame close to the gear, and the guide frame is movably connected to the eccentric position of the gear through the movable groove.

[0009] Optionally, a clamping rod is also included, which is rotatably connected to the tilting rod head, a stopper is fixed to the tilting rod head, the stopper contacts the top of the clamping rod, and a torsion spring symmetrically distributed along the clamping rod is fixed between the clamping rod and the tilting rod head.

[0010] Optionally, a push frame is also included, which is sleeved outside the main pipe, the push frame is in contact with the bottom of the clamping rod, and the push frame is fixed to the main pipe by a nut.

[0011] Optionally, a reinforcing tube is fixedly connected to a connection portion of the push rod close to the main pipe and the connecting pipe and a connection portion of the slide rod close to two adjacent connecting pipes.

[0012] Optionally, the reinforcing cylinder is provided with circumferentially distributed spiral grooves.

[0013] Optionally, both the main pipe and the connecting pipe are covered with a gripping tube with a smooth inner wall.

[0014] Optionally, it also includes clamping plates symmetrically distributed along the grip tube, the clamping plates are rotatably connected to adjacent grip tubes, the clamping plates are provided with rough clamping surfaces, and the grip tubes are provided with limiters symmetrically distributed along adjacent clamping plates, and the limiters are used to fix adjacent clamping plates.

[0015] Optionally, a cartridge is also included, and the cartridge is threadedly connected to the bottom of the connecting pipe at the bottom.

[0016] The beneficial effect is that when the device is held in hand, when it is suitable for removing a flat lift bar, by pushing it down slightly, the bottom end of the slide bar hits any external fixed object around the constructor, and it can be switched to a flat lift bar with a large angle. When it is suitable for removing a curved hook lift bar, by pressing the card frame with the thumb, it can be switched to a curved hook lift bar with a small angle. The operation is simple and convenient, and there is no need to frequently flip the two ends for switching, which reduces the physical burden.

[0017] After the template is pried open with a large-angle flat lifting rod, the invention can immediately switch to a small-angle curved hook lifting rod, so that progressive angle removal is achieved. With the help of the rotational force of the lifting rod head, the template can be removed more easily, saving worry and effort.

[0018] In the hook and lift rod mode, the present invention forms a claw-type lift rod by cooperating with the lift rod head. In this way, it is more convenient to apply force to remove when clamping the raised structure of the template (such as bolts, locating pins) or hooking the edge and hole of the template.

[0019] The present invention can increase the strength of the connection between the main pipe and the connecting pipe and the connection between the adjacent connecting pipes by arranging the reinforcing tube to prevent the connection from breaking, and reduce the weight of the reinforcing tube by hollowing out the spiral groove in the reinforcing tube, making the device easier to hold.

[0020] The present invention increases the friction force of holding the hand and improves the comfort of holding the hand by arranging the grip tube, so that the device is convenient to hold tightly, and the position of the grip tube can be adjusted by sliding up and down by rotating the clamping plate upward.

[0021] The present invention can fix the device in a flat tilting rod mode by screwing a short cartridge on the bottom of the lowest connecting tube, and can fix the device in a bent hook tilting rod mode by screwing a long cartridge on the bottom of the lowest connecting tube.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0035] Embodiment 1: A progressive wall building template removal device, such as Figure 1-Figure 4 As shown, it includes a main pipe 1 and a connecting pipe 2, the upper part of the connecting pipe 2 is provided with an external thread groove, the main pipe 1 is connected to the external thread groove of the connecting pipe 2, and the lower part of the connecting pipe 2 is provided with an internal thread groove. By spirally connecting the internal thread of the upper connecting pipe 2 with the external thread of the next connecting pipe 2, multiple connecting pipes 2 can be connected at the bottom of the connecting pipe 2 to extend the overall length of the device, the top of the main pipe 1 is rotatably connected to a tilting rod head 3, the upper side of the inner part of the main pipe 1 is rotatably connected to a gear 4, the tilting rod head 3 is meshed with the gear 4, the inner part of the main pipe 1 is slidably connected to a push rod 5 in the up-down direction, the upper side of the main pipe 1 is slidably connected to a guide frame 501 in the up-down direction, and the upper end of the push rod 5 is connected to the guide frame 501 Contact, a movable groove is opened on the upper side of the guide frame 501, and the guide frame 501 is movably connected to the eccentric position of the gear 4 through the movable groove. The guide frame 501 moves up and down to push and pull the gear 4 to rotate forward and backward. A spring 6 is fixedly connected between the main pipe 1 and the guide frame 501, and a slide rod 7 is slidably connected in the connecting pipe 2 along the up and down directions. The lower end of the push rod 5 contacts the adjacent slide rod 7, and the slide rod 7 is fixedly connected with a block 701 symmetrically distributed along the slide rod 7. A bracket 8 is slidably connected to the connecting pipe 2 along the left and right directions. The side of the bracket 8 close to the adjacent block 701 is set as an inclined surface, and the inclined surface of the bracket 8 is squeezed and matched with the adjacent block 701. A tension spring 9 is fixedly connected between the bracket 8 and the adjacent connecting pipe 2.

[0036] Each connecting tube 2 and its internal and external components constitute a connecting assembly. Several new connecting assemblies can be screwed onto the bottom of the connecting tube 2 through a progressive downward thread to achieve the effect of progressively extending the length of the device. In the process of removing the wall building formwork, if a large-angle flat tilting rod is needed, the device is held downward for a while so that the bottom end of the slide bar 7 hits any external fixed object around the constructor, thereby causing the slide bar 7 to slide upward, and the slide bar 7 pushes the push rod 5 to move upward, and the push rod 5 pushes the guide frame 501 to move upward, the spring 6 is compressed, and the guide frame 501 is moved upward. The positioning frame 501 pushes the gear 4 to rotate counterclockwise, thereby driving the tilting rod head 3 to rotate clockwise, thereby increasing the angle between the tilting rod head 3 and the main pipe 1; and in the process of pushing the slide bar 7 upward, the slide bar 7 drives the block 701 to move upward, and the block 701 squeezes the inclined surface of the card frame 8, so that the card frame 8 slides to one side of the tension spring 9. When the block 701 is disengaged from the inclined surface of the card frame 8, the tension spring 9 is reset and drives the card frame 8 to slide and reset. At this time, the card frame 8 clamps the block 701, so that the slide bar 7 cannot slide downward, thereby fixing the tilting rod head 3 in the adjusted position.

[0037] If it is necessary to use a small-angle bent hook tilting rod, press the card frame 8 with the thumb to make the card frame 8 slide to the side of the tension spring 9 again, thereby releasing the limit of the card frame 8 on the card block 701, and the spring 6 resets to drive the push rod 5 and the guide frame 501 to slide downward, and the push rod 5 pushes the slide bar 7 to slide downward and reset, and the guide frame 501 pulls the gear 4 to reverse and reset, thereby driving the tilting rod head 3 to rotate counterclockwise, so as to reduce the angle between the tilting rod head 3 and the main pipe 1.

[0038] In summary, when the device is held in hand, when it is suitable for removing a flat lift bar, it can be switched to a flat lift bar with a large angle by pushing it downward so that the bottom end of the slide bar 7 hits any external fixed object around the constructor. When it is suitable for removing a curved hook lift bar, it can be switched to a curved hook lift bar with a small angle by pressing the card frame 8 with the thumb. The operation is simple and convenient. In this way, there is no need to frequently flip the two ends for switching, thereby reducing the physical burden.

[0039] In addition, after the present invention uses a large-angle flat lifting rod to pry open the template, it can also immediately switch to a small-angle curved hook lifting rod, so that progressive angle removal is achieved. With the help of the rotational force of the lifting rod head 3, the template can be removed more easily, saving worry and effort.

[0040] Embodiment 2: Based on embodiment 1, Figure 5 and Figure 6As shown, it also includes a clamping rod 10, which is rotatably connected to the tilting rod head 3. A stopper 101 is fixedly connected to the tilting rod head 3, and the stopper 101 contacts the top of the clamping rod 10. A torsion spring 11 is fixedly connected between the clamping rod 10 and the tilting rod head 3 and is symmetrically distributed along the front and back of the clamping rod 10. A push frame 12 is arranged on the outer sleeve of the main pipe 1, and the push frame 12 contacts the bottom of the clamping rod 10. The push frame 12 is fixed to the main pipe 1 by a nut 13.

[0041] In the hook and tilting lever mode, a claw-type tilting lever is formed by cooperating with the tilting lever head 3 through the clamping rod 10. In this way, when clamping the raised structure of the template (such as bolts, locating pins), or hooking the edge or hole of the template, it is more convenient to apply force to remove it. In the flat tilting lever head 3 mode, the tilting lever head 3 drives the clamping rod 10, the block 101 and the torsion spring 11 to rotate clockwise synchronously, so that the clamping rod 10 gradually disengages from the push frame 12, and the torsion spring 11 gradually resets and drives the clamping rod 10 to rotate and embed into the tilting lever head 3. In addition, when it is not necessary to form a claw-type tilting lever in the hook and tilting lever mode, loosen the nut 13 and then remove the push frame 12 downward.

[0042] Embodiment 3: Based on embodiment 2, Figure 7-Figure 11 As shown, the lower parts of the push rod 5 and the slide rod 7 are fixedly connected with a reinforcing tube 14, and the reinforcing tube 14 has a circumferentially distributed spiral groove 141. The main pipe 1 and the connecting pipe 2 are both covered with a grip tube 15 with a smooth inner wall. The grip tube 15 is rotatably connected with a clamping plate 16 symmetrically distributed along the grip tube 15, and the opposite surfaces of the two adjacent clamping plates 16 are provided with a rough clamping surface. The grip tube 15 is provided with a limiter 17 symmetrically distributed along the adjacent clamping plates 16. The limiter 17 is composed of a limit block and a spring thereon. The limiter 17 is used to fix the adjacent clamping plates 16. The bottom of the connecting pipe 2 at the bottom is threadedly connected with a clamping tube 18. The clamping tube 18 has different lengths and can be replaced.

[0043] The present invention can increase the strength of the connection between the main pipe 1 and the connecting pipe 2 and the connection between the adjacent connecting pipes 2 by providing a reinforcing tube 14 to prevent the connection from breaking, and reduce the weight of the reinforcing tube 14 by hollowing out the spiral groove 141 in the reinforcing tube 14, making the device easier to hold.

[0044] In order to facilitate holding the device, a grip tube 15 is provided to increase the friction of holding the device and improve the comfort of holding the device. When it is necessary to adjust the grip tube 15 to a suitable position up or down, the clamping plate 16 is first rotated upward, and the clamping plate 16 squeezes the limiter 17. In this way, the rough clamping surface of the clamping plate 16 is separated from the outer surface of the main pipe 1 or the connecting pipe 2, and the grip tube 15 with a smooth inner surface can slide up and down. When it is necessary to fix the grip tube 15, the clamping plate 16 is rotated downward, so that the rough clamping surface of the clamping plate 16 contacts the outer surface of the main pipe 1 or the connecting pipe 2. At this time, the limiter 17 limits and fixes the clamping plate 16.

[0045] If only a large-angle flat tilt rod mode is needed, a short cartridge 18 is screwed on the bottom of the bottom connecting tube 2 so that the inner bottom of the short cartridge 18 contacts the bottom end of the bottom slide rod 7. If only a small-angle hook tilt rod mode is needed, a long cartridge 18 is screwed on the bottom of the bottom connecting tube 2 so that the inner bottom of the long cartridge 18 contacts the bottom end of the bottom slide rod 7. In this way, the needs of more modes can be met.

[0046] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
