Description

Technical Field

[0001] This application relates to the field of aluminum formwork installation and dismantling construction technology, and in particular to a reusable aluminum formwork pull tab and a matching dismantling device and its usage method. Background Technology

[0002] Traditional tools for removing pull-tab aluminum formwork involve using two tools together: a long-handled pull-tab remover for removing the upper, higher pull-tabs on the wall, and a hammer for removing the lower, middle pull-tabs. For this type of pull-tab aluminum formwork, a standard flat-headed hammer is first used to knock away the lower, middle pull-tabs, while a flat-end steel pipe is used to clean the upper pull-tabs. This method is inefficient and requires repeated tool changes. Furthermore, when using a flat-headed hammer, the lateral movement of the hammer causes the pull-tabs to shift, making them harder to remove. This also causes concrete to be squeezed and detached from the pull-tab area, creating a quality and aesthetic risk. Additionally, the pull-tab fragments that fall to the ground are not collected and are treated as construction waste, which is detrimental to environmental protection and resource recycling.

[0003] Therefore, there is an urgent need to study an aluminum formwork removal method that can effectively improve the construction efficiency of aluminum formwork removal, effectively ensure the overall quality of the structure, and have a positive effect on environmental protection and resource recycling.

[0040] 3. The reset spring drives the button to swing the control lever in the opposite direction, causing the movable pin to disengage from the pin hole. At this time, the pull tab end is released from its restraint. Simply lift and shake the head of the removal rod, and the removed pull tab end can enter the hose through the cavity in the removal rod and finally be transported to the collection box for collection.

[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0059] Reference Figure 1 , Figure 2 and Figure 3 This application discloses a reusable aluminum mold pull sheet and a matching removal device.

[0060] Its aluminum die sheet includes:

[0061] The pull tab has a middle part 1 and two pull tab ends 2 at its two ends. A locking structure is provided between the pull tab ends 2 and the pull tab middle part 1 to lock / unlock after the two are rotated to a set angle. The pull tab ends 2 have a pin hole 21.

[0062] Specifically, the locking structure includes:

[0063] The connecting buckle 22 includes a connecting part 221 and a buckle part 222. The connecting part 221 is fixed to the end of the pull tab 2. The width of the buckle part 222 is greater than the width of the connecting part 221. The buckle part 222 is perpendicular to the connecting buckle 22, so that the end of the pull tab 2 can be locked / unlocked after rotating 90° relative to the middle part 1 of the pull tab.

[0064] Two buckle cylinders 11 are provided and are respectively fixed to both ends of the middle part 1 of the pull tab. The inner diameter of the buckle cylinder 11 is not less than the width of the buckle part 222.

[0065] The limiting cylinder 12 is fixedly connected to the hollow part of the buckle cylinder 11 away from the middle part 1 of the pull tab. The limiting cylinder 12 has a transverse groove 121 through which the buckle part 222 is inserted and enters the hollow part of the buckle cylinder 11. The axial length of the limiting cylinder 12 along the buckle cylinder 11 is not less than the length of the connecting part 221, and the inner diameter of the limiting cylinder 12 is not less than the width of the connecting part 221 and not greater than the width of the buckle part 222.

[0066] Furthermore, when the end 2 of the pull tab rotates to be flush with the middle part 1 of the pull tab, the latching part 222 does not correspond to the horizontal groove 121.

[0067] Reference Figure 4 , Figure 5 and Figure 6 Its dismantling device includes:

[0068] Remove rod 3, which has through ends and an internal cavity;

[0069] Collection box 41 is used to collect the removed pull tab ends 2. Specifically, it is equipped with a removable inner liner. When the inner liner is full of pull tab ends 2, the inner liner can be removed and transferred.

[0070] Hose 42, used to connect the removal rod 3 and the collection box 41;

[0071] The fixing pin 51 is fixed in the cavity of the removal rod 3;

[0072] The movable pin 52 has a gap between it and the fixed pin 51 for the end 2 of the pull tab to extend into, and is adapted to be inserted into the pin hole 21; and

[0073] A control mechanism is used to drive the movable pin 52 toward the fixed pin 51 and lock the pin hole 21 on the pull tab end 2 that extends into the cavity of the removal rod 3.

[0074] Therefore, by setting the aluminum formwork pull tab as a pull tab middle part 1 and two pull tab ends 2, and realizing the simple snap-fit ​​connection between the pull tab ends 2 and the pull tab middle part 1 through the cooperation of the snap-fit ​​cylinder 11 and the connecting snap 22, the pull tab ends 2 and the pull tab middle part 1 can be conveniently and detachably connected. After the aluminum formwork pull tab is used, the pull tab ends 2 can be recycled and reused, which can effectively improve the efficiency of aluminum formwork pull tab removal construction, and reduce the material loss rate by reusing the pull tab ends 2.

[0075] By setting the removal device as a removal rod 3 plus a collection box 41, when removing the pull tab end 2, the construction personnel only need to align the head of the removal rod 3 with the pull tab end 2, so that the pull tab end 2 is embedded in the cavity of the removal rod 3 and the movable pin 52 in the removal rod 3 is aligned with the pin hole 21 on the pull tab end 2. Then, the control mechanism drives the movable pin 52 through the pin hole 21 and abuts against the fixed pin 51. At this time, the pull tab end 2 is confined in the cavity of the removal rod 3. Simply rotate the removal rod 3 to drive the pull tab end 2 to rotate on the middle part 1 of the pull tab, so that the buckle part 222 is aligned with the transverse groove 121 on the limiting cylinder 12. Then pull the removal rod 3 to make the connecting buckle 22 disengage from the buckle cylinder 11, and the removal of the pull tab end 2 on the middle part 1 of the pull tab can be completed. This makes the removal process of the pull tab end 2 simple and efficient.

[0076] Then, the control mechanism drives the movable pin 52 to disengage from the pin hole 21. At this time, the pull tab end 2 is released from restriction. Only the head of the removal rod 3 needs to be lifted. The removed pull tab end 2 can enter the hose 42 through the cavity in the removal rod 3 and finally be transported to the collection box 41 for collection. The process of disassembling, transporting and collecting aluminum mold pull tabs is integrated into the construction process, which effectively reduces environmental pollution during construction, avoids secondary cleaning and reduces labor costs. Moreover, the construction progress can be effectively improved by completing the construction process in one go, and the construction period can be greatly saved.

[0077] Specifically, to facilitate the operation of construction personnel, refer to Figure 4 , Figure 5 and Figure 6 The control mechanism includes:

[0078] The movable rod 61 is located inside the cavity of the removal rod 3 and one end is fixedly connected to the movable pin 52.

[0079] The control lever 62 is fixedly connected to the movable lever 61. The connection part 221 between the control lever 62 and the movable lever 61 is hinged to the removal lever 3, and the hinge axis of the two is orthogonal to the axis of the movable pin 52.

[0080] Button 63 is located at one end of the removal rod 3 near the hose 42 and is connected to the control rod 62. When button 63 is pressed, the control rod 62 is driven to rotate inside the removal rod 3 so that the movable pin 52 approaches the fixed pin 51.

[0081] A short lever is used to connect the button 63 and the control lever 62. A return spring (not shown in the figure) is provided on the outer sleeve of the short lever. One end of the return spring is pressed against the button 63 and the other end is pressed against the release lever 3.

[0082] Furthermore, a fork block 7 is fixedly connected to one end of the movable rod 61 near the control rod 62. The width of the fork of the fork block 7 is not less than the thickness of the pull tab end 2. When the pull tab end 2, which enters the cavity of the removal rod 3, is embedded in the fork of the fork block 7, the movable pin 52 is aligned with the pin hole 21.

[0083] Furthermore, a baffle 8 is fixedly connected to the cavity of the removal rod 3. A positioning groove 81 is provided through the middle of the baffle 8 for the end of the pull tab 2 to pass through. The positioning groove 81 corresponds to the fork of the fork block 7, and the width of the positioning groove 81 is greater than the thickness of the end of the pull tab 2. The fixed pin 51 and the movable pin 52 are both located on the side of the baffle 8 away from the hose 42, and the fixed pin 51 is fixed to the baffle 8.

[0084] A sealing plate 9 is fixed to one end of the removal rod 3 away from the hose 42. A positioning hole 91 is opened through the sealing plate 9. When the end of the pull tab 2 that enters the cavity of the removal rod 3 is embedded in the fork of the fork block 7 and fits against the lower side wall of the positioning hole 91, the movable pin 52 is completely aligned with the pin hole 21.

[0085] Therefore, when the construction worker holds the removal rod 3 and places its head end on the pull tab end 2, the pull tab end 2 first passes through the positioning hole 91 on the sealing plate 9, which can limit the position of the pull tab end 2 in the vertical direction to a certain extent; then the pull tab end 2 passes through the positioning groove 81 on the baffle 8, which can limit the amount of swaying of the pull tab end 2 in the horizontal plane to a certain extent; and when the head end of the pull tab end 2 is pressed against the fork of the fork block 7 on the movable rod 61, the pull tab end 2 can be limited in the depth direction in the horizontal plane. At this time, after being limited or positioned in three directions, the pin hole 21 on the pull tab end 2 can be accurately aligned with the movable pin 52, ensuring that the construction worker can lock the pull tab end 2 when pressing it against the pull tab end 2 with the removal rod 3, without the need for complicated positioning and calibration operations, which greatly improves the operating efficiency.

[0086] To continue operation, simply press button 63. The reset spring is compressed, and button 63 pushes the control rod 62 to swing in the removal rod 3 via the short rod. This causes the movable pin 52 on the movable rod 61 to move towards the fixed pin 51 and pass through the pin hole 21 on the pull tab end 2. At this time, the pull tab end 2 is stably locked, and the removal rod 3 can be rotated to remove the pull tab end 2. After removal, release button 63. Under the deformation force of the reset spring, button 63 pulls the control rod 62 to swing in the opposite direction via the short rod, causing the movable pin 52 to move away from the fixed pin 51. The operator then shakes the head end of the removal rod 3 laterally and raises the head end, causing the pull tab end 2 to come out of the fork of the fork block 7 and slide completely into the cavity of the removal rod 3 in the gap on the side of the fork block 7 away from the movable rod 61, thus completing the collection of the removed pull tab end 2.

[0087] Additionally, refer to Figure 4 and Figure 5 The removal rod 3 has a curved grip 31 at one end near the hose 42, and a button 63 is located at the grip 31. The curved grip 31 allows construction workers to remove the end 2 of the pull tab at a higher position on the wall column while standing on the ground, making it more practical.

[0088] This application also discloses a method for removing reusable aluminum mold pull tabs. Based on the above-mentioned reusable aluminum mold pull tab and matching removal device, the following technical solution is adopted:

[0089] A method for removing reusable aluminum mold pull tabs includes the following steps:

[0090] S1. Aluminum formwork removal: After the main structure wall and column concrete is poured and reaches the set strength, the aluminum formwork is removed so that the end 2 of the tie plate is exposed outside the wall and column.

[0091] S2. Pull tab removal: Hold the removal rod 3 so that the pull tab end 2 is inserted into the cavity of the removal rod 3. After the movable pin 52 is aligned with the pin hole 21 on the pull tab end 2, the movable pin 52 is controlled by the control mechanism to pass through the pin hole 21 and abut against the fixed pin 51. Rotate the removal rod 3 to unlock the pull tab end 2 and the pull tab end 2 by means of the locking structure. Then pull the pull tab end 2 out from the middle part 1 of the pull tab.

[0092] S3. Pull the tab to collect, lift the head of the removal rod 3 and release the movable pin 52, so that the removed tab end 2 slides along the cavity of the removal rod 3 and the hose 42 into the collection box 41;

[0093] S4. Pull-out cleaning: After the collection box 41 is full, transfer the pull-out end 2 for next use.

[0094] The implementation principle of a reusable aluminum mold sheet in this application embodiment is as follows:

[0095] By setting the aluminum formwork pull tab as a pull tab middle part 1 and two pull tab ends 2, and realizing the simple snap-fit ​​connection between the pull tab ends 2 and the pull tab middle part 1 through the cooperation of the snap-fit ​​cylinder 11 and the connecting snap 22, the pull tab ends 2 and the pull tab middle part 1 can be conveniently and detachably connected. After the aluminum formwork pull tab is used, the pull tab ends 2 can be recycled and reused, which can effectively improve the efficiency of aluminum formwork pull tab removal construction, and reduce the material loss rate by reusing the pull tab ends 2.

[0096] By setting the removal device as a removal rod 3 plus a collection box 41, when removing the pull tab end 2, the construction personnel only need to align the head of the removal rod 3 with the pull tab end 2, so that the pull tab end 2 is embedded in the cavity of the removal rod 3 and the movable pin 52 in the removal rod 3 is aligned with the pin hole 21 on the pull tab end 2. Then, press the button 63 to make the control rod 62 drive the movable rod 61 to swing so that the movable pin 52 passes through the pin hole 21 and abuts against the fixed pin 51. At this time, the pull tab end 2 is confined in the cavity of the removal rod 3. Simply rotate the removal rod 3 to drive the pull tab end 2 to rotate on the middle part 1 of the pull tab, and then align the buckle part 222 with the transverse groove 121 on the limiting cylinder 12. Then pull the removal rod 3 to make the connecting buckle 22 disengage from the buckle cylinder 11, and the removal of the pull tab end 2 on the middle part 1 of the pull tab can be completed. This makes the removal process of the pull tab end 2 simple and efficient.

[0097] Then, the reset spring drives the button 63 to swing the control rod 62 in the opposite direction, causing the movable pin 52 to disengage from the pin hole 21. At this time, the pull tab end 2 is released from its restraint. Simply lift and shake the head of the removal rod 3, and the removed pull tab end 2 can enter the hose 42 through the cavity in the removal rod 3 and finally be transported to the collection box 41 for collection. In this way, the disassembly, transmission and collection process of aluminum mold pull tabs is integrated into the construction process, which can effectively reduce environmental pollution during construction, avoid secondary cleaning and reduce labor costs. Moreover, by completing the construction process in one go, the construction progress can be effectively improved and the construction period can be greatly saved.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
