Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for quick dismantling of building formwork. Background Technology

[0002] In the construction process, formwork is an important tool for concrete shaping, and the efficiency and safety of formwork removal operations directly affect the project progress and construction costs.

[0003] The principle of the early stripping support system: When the concrete strength requirement at the time of bottom formwork removal meets the requirements of GB50204 "Code for Acceptance of Construction Quality of Concrete Structures", a portion of the narrow bottom formwork, early stripping support head, and curing support are retained and then removed. There is a time difference between removing the formwork when the concrete compressive strength reaches 100% of the designed standard value and removing the formwork when it reaches 50% or 75%. By making full use of the time difference, the bottom formwork and its support system can be removed early, accelerating the turnover of formwork, reducing formwork investment, and lowering costs.

[0004] Traditional devices for early and quick removal of building formwork typically involve adjusting the height of the supporting joists using a threaded mechanism, or installing elongated rings under the supporting joists. By hammering these rings, the formwork is displaced from the supporting joists and falls, thus stopping support on the joists and enabling quick removal.

[0005] However, the threaded type requires workers to slowly rotate and adjust it, which is not very efficient. Setting the long ring requires the use of external tools such as hammers, and the structure is easily damaged due to operational errors when hammering, which is not conducive to use. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a device for quick dismantling of building formwork, in view of the above-mentioned problems.

[0007] The technical solution adopted by this utility model is: a device for quick dismantling of building formwork, comprising:

[0008] The support mechanism has a sliding component inside, and the outer wall of the sliding component is connected to a supporting keel located outside the support mechanism. The sliding component can slide along the axis of the support mechanism itself to adjust the support height of the supporting keel. The top of the support mechanism can provide support for the building formwork.

[0009] The quick-release mechanism includes an elastic clamping component and a squeezing component. The elastic clamping component is located inside the support mechanism and on the periphery of the sliding component. The elastic clamping component can clamp and fix the sliding component under elastic action. The squeezing component is slidably located inside the support mechanism. The squeezing component can slide along the axial direction of the support mechanism to squeeze or move away from the elastic clamping component, so that the elastic clamping component expands outward to release the sliding component or retracts inward to clamp the sliding component accordingly.

[0010] Through the above-mentioned technical means, this solution adopts a structure in which sliding components, elastic clamping components, and extrusion components cooperate with each other. The clamping and release of the elastic clamping components can be controlled by the axial sliding of the extrusion components, thereby realizing the rapid descent of the supporting keel. No complicated operation is required, which greatly improves the demolding efficiency and effectively improves the speed compared with the traditional threaded adjustment.

[0011] In some embodiments, the support mechanism includes a top support, a column, and a telescopic upright. The column is slidably fitted onto the outside of the telescopic upright. The top of the column is provided with a top support capable of supporting the building formwork. The supporting keel is slidably fitted onto the outside of the column. A sliding component is slidably provided inside the column. The outer wall of the sliding component is connected to a supporting keel that partially penetrates the side wall of the column, so that the supporting keel can adjust the support height by sliding the sliding component. A buffer component capable of absorbing the impact of the supporting keel falling is provided between the outer wall of the column and the bottom of the supporting keel.

[0012] In some embodiments, the sliding assembly includes a slider and a movable seat. The inner top of the support column is provided with a movable groove, in which the slider is slidably connected. The bottom of the slider is connected to the movable seat.

The inside of the support column is symmetrically hinged with a lever assembly, the output end of the lever assembly corresponds to the bottom of the squeezing assembly, and the lever assembly can drive the squeezing assembly to slide and squeeze the elastic clamping assembly.

[0013] In some embodiments, the elastic clamping assembly includes a locking plate, a limiting rod, and a first spring. A set of locking plates are symmetrically arranged on both sides of the movable seat. Multiple limiting rods are provided through the locking plates. The two ends of the limiting rods are connected to the inner wall of the support column. A first spring located between the set of locking plates is sleeved on the limiting rod. The bottom sides of the set of locking plates are provided with tapered surfaces.

[0014] In some embodiments, the inner wall of the locking plate is hinged with a pawl, the upper surface of the pawl is planar and the lower surface of the pawl is inclined. The movable seat is provided with a plurality of ratchet blocks facing the outer wall of the locking plate. The upper surface of the ratchet blocks is inclined and the lower surface of the ratchet blocks is planar. The pawl and the ratchet blocks can abut against each other. The locking plate is also provided with an elastic member that can abut against the pawl. The elastic member can provide a restoring force to the pawl after being squeezed.

[0015] In some embodiments, the lever assembly includes a shaft, a rocker arm, and a lever arm. The shaft is symmetrically rotatably mounted inside the support column. One side of the shaft is connected to a rocker arm that abuts against the bottom of the extrusion assembly. The other side of the shaft is connected to a lever arm that extends to the outside of the support column, such that pulling the lever arm can drive the rocker arm to push the extrusion assembly around the shaft. The length of the lever arm is greater than the length of the rocker arm.

[0016] In some embodiments, the extrusion assembly includes a top seat, a limiting plate, and a first locking member. The top of the telescopic upright is connected to the limiting plate, and the top seat located inside the support column is slidably sleeved outside the limiting plate. The top of the top seat is provided with an inclined surface that can abut against the elastic clamping assembly. The bottom outer wall of the support column is provided with the first locking member, which can lock the position of the top seat.

[0017] In some embodiments, the first locking member includes a first slot and a plug. The outer walls on both sides of the top seat are provided with a plurality of first slots. The outer wall of the column is provided with an opening that corresponds to the first slot. The plug can pass through the opening and be inserted into the first slot to lock the position of the top seat.

[0018] In some embodiments, the buffer assembly includes a connecting rod, a swing arm, a movable block, a damper, a second spring, and a second locking member. The bottom sides of the supporting keel are symmetrically hinged with connecting rods, and the ends of the connecting rods away from the supporting keel are hinged with movable blocks. The outer wall of the support column located on the same side as the connecting rods is hinged with a swing arm. The swing arm has a second chamber inside, and a damper is installed inside the second chamber. The end of the damper is connected to a movable block that can slide inside the second chamber. A second spring is sleeved on the outside of the damper, and a second locking member that can lock the position of the movable block is provided through the swing arm.

The bolt can pass through the opening and be inserted into the second slot to lock the position of the movable block.

[0020] The beneficial effects of this utility model are:

[0021] 1. This solution employs a structural design that combines sliding components, elastic clamping components, and extrusion components. A support mechanism provides support for the building formwork. The sliding component allows adjustment of the support height of the supporting keel and its own top. Under normal operating conditions, the elastic clamping component provides a stable clamping force to the sliding component, ensuring reliable support. The clamping and releasing of the elastic clamping component can be controlled by the axial sliding of the extrusion component, thereby enabling rapid descent of the sliding component and supporting keel. This achieves non-rotational, non-hammering quick dismantling, significantly improving demolding efficiency. Operation is safe, highly controllable, and avoids the risk of structural damage caused by hammering.

[0022] 2. In the quick-release mechanism, this device utilizes a lever structure formed by a lever arm, a rocker arm, and a shaft. The operator only needs to pull the lever arm to make the rocker arm swing. Using the lever principle, the squeezing component can be pushed with a small force, causing the squeezing component to squeeze the elastic clamping component, thereby quickly releasing the lock on the sliding component. The device and the template can be separated quickly. The template can be easily removed without the need for additional tools. It is not only simple to operate, labor-saving and efficient, but also avoids damage to the template and concrete structure, effectively improving construction efficiency and reducing labor intensity and safety risks.

[0033] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0034] Combination Figures 1 to 5As shown, this embodiment is a device for quick dismantling of building formwork, including a support mechanism 1 and a quick dismantling mechanism 2. A sliding component is slidably disposed inside the support mechanism 1, and a supporting keel 104 located outside the support mechanism 1 is connected to the outer wall of the sliding component. The sliding component can slide along the axial direction of the support mechanism 1 to adjust the support height of the supporting keel 104. The top of the support mechanism 1 can provide support for the building formwork. The quick dismantling mechanism 2 includes an elastic clamping component and a pressing component. The elastic clamping component is disposed inside the support mechanism 1 and located around the sliding component. The pressing component is slidably disposed inside the support mechanism 1 and located at the bottom of the sliding component. The elastic clamping component can clamp and fix the sliding component under elastic action. The pressing component can slide along the axial direction of the support mechanism 1, causing the pressing component to move closer to and press against the elastic clamping component. The elastic clamping component can expand outward to release the sliding component, or the pressing component can move away to release the elastic clamping component. The elastic clamping component can retract inward to clamp the sliding component under elastic action, thereby fixing the support height of the sliding component and the support mechanism 1.

[0035] In some implementation schemes, such as Figure 1 As shown, the support mechanism 1 includes a top support 103, a column 102, and a telescopic upright 101. The telescopic upright 101 is adjustable in length and retraction. The column 102 is slidably fitted onto the outside of the telescopic upright 101. The top of the column 102 is provided with a top support 103 that can support the building formwork. The support height of the top support 103 can be adjusted by extending and retracting the telescopic upright 101 along its own axis. A supporting keel 104 is slidably fitted onto the outside of the column 102. A sliding component is slidably provided inside the column 102. The outer wall of the sliding component is connected to a supporting keel 104 that partially penetrates the side wall of the column 102, so that the supporting keel 104 can adjust its support height by sliding the sliding component. A buffer component 3 is provided between the outer wall of the column 102 and the bottom of the supporting keel 104 to absorb the impact of the supporting keel 104 falling.

[0036] Using the telescopic upright 101 as a fixed foundation support, the support column 102 can slide up and down along the telescopic upright 101 to adjust the support height of the top support 103. In this embodiment, the top support 103 mainly supports the concrete structure of the top column through the curing board. The sliding component drives the supporting keel 104 to move, adjusting the support height of the supporting keel 104, which can support the beam formwork. During quick dismantling, the supporting keel 104 falls rapidly; without cushioning, this will generate a violent impact, easily causing structural fatigue or formwork deformation. In this embodiment, the buffer component 3 absorbs kinetic energy, slows down the falling speed, and reduces the risk of collapse.

[0037] In some implementation schemes, such as Figure 2As shown, the sliding assembly includes a slider 105 and a movable seat 106. The inner top of the support column 102 is provided with a movable groove 108, in which the slider 105 is slidably connected. The bottom of the slider 105 is connected to the movable seat 106. The inner bottom of the support column 102 is provided with a first chamber, in which an elastic clamping assembly and a pressing assembly are provided. The elastic clamping assembly is symmetrically arranged on both sides of the movable seat 106, and the clamping end of the elastic clamping assembly corresponds to the periphery of the movable seat 106. The pressing assembly is located below the movable seat 106. A lever assembly is symmetrically hinged inside the support column 102, and the output end of the lever assembly corresponds to the bottom of the pressing assembly. The lever assembly can drive the pressing assembly to slide and press the elastic clamping assembly.

[0038] In this embodiment, the movable groove 108 is adapted to the movement trajectory of the slider 105. The movable groove 108 can limit the range of motion of the slider 105, which not only ensures that the slider 105 does not deviate in vertical movement, but also limits the descent distance of the supporting keel 104, so that the crossbeam template it supports will not fall directly to the ground and be damaged.

[0039] In some implementation schemes, such as Figure 3 As shown, the elastic clamping assembly includes a locking plate 107, a limiting rod 1071, and a first spring 1072. A set of locking plates 107 are symmetrically arranged on both sides of the movable seat 106. Multiple limiting rods 1071 are slidably provided through the locking plates 107. The two ends of the limiting rods 1071 are connected to the inner wall of the support column 102. The first spring 1072 located between the set of locking plates 107 is sleeved on the limiting rods 1071. The bottom of the set of locking plates 107 has a tapered surface 203 that can abut against the extrusion assembly.

[0040] The locking plate 107 is positioned and guided by the limiting rod 1071, ensuring it can only move stably along the axial direction of the limiting rod 1071. The first spring 1072 applies a pulling force to the locking plate 107 towards the movable seat 106 using its elasticity. When the pressing component moves downward and disengages from the locking plate 107, the first spring 1072 pulls the locking plate 107 back into contact with the movable seat 106 due to the disappearance of resistance, thus limiting the position of the movable seat 106 and the supporting keel 104. The first spring 1072 continuously pushes the locking plate 107 inward, and it automatically returns to the clamping state once the pressing is released. Relocking can be completed without manual intervention, making it suitable for reusable scenarios.

[0041] Furthermore, such as Figure 3As shown, the inner wall of the locking plate 107 is arranged in an array with multiple pawls 1074. The pawls 1074 are hinged to the inner wall of the locking plate 107. The upper surface of the pawls 1074 is flat, and the lower surface of the pawls 1074 is inclined. The movable seat 106 is provided with multiple ratchet blocks 1073 facing the outer wall of the locking plate 107. The upper surface of the ratchet blocks 1073 is inclined, and the lower surface of the ratchet blocks 1073 is flat. The pawls 1074 and the ratchet blocks 1073 can abut against each other. The locking plate 107 is also provided with an elastic member 1075 that can abut against the pawls 1074. The elastic member 1075 can provide a restoring force to the pawls 1074 after being compressed. Specifically, in this embodiment, the elastic member 1075 includes, but is not limited to, irregularly shaped springs, rubber strips, etc.

[0042] The ratchet 1074 and ratchet block 1073 work together to form a mechanical self-locking mechanism. When the movable seat 106 moves upward, the inclined plane guides the locking plate 107 to expand outward, but the first spring 1072 pulls back to keep it clamped. When the movable seat 106 slides downward unexpectedly, the plane abuts against it to prevent it from sliding back and to prevent it from loosening. Under load, it can play an anti-slip role and ensure construction safety.

[0043] When the device is installed and used, it can push the supporting keel 104 upward, so that it contacts the crossbeam and presses the formwork onto the concrete structure to complete the stable support. When the supporting keel 104 moves upward, it will drive several ratchet blocks 1073 to move upward through the movable seat 106. Since the upper surface of the ratchet block 1073 and the lower surface of the pawl 1074 are both set with slopes, the pawl 1074 is hinged to the locking plate, and the top of the pawl 1074 has a certain amount of room to move. During the upward movement of the ratchet block 1073, it will generate a diagonal pushing force on the pawl 1074 when it contacts it, thereby rotating it. When the pawl 1074 is pushed open, it compresses the elastic element 1075 to accumulate potential energy. After the ratchet block 1073 passes the pawl 1074, the elastic potential energy accumulated by the elastic element is released, pushing the pawl 1074 back to its original position. Since the lower surface of the ratchet block 1073 and the upper surface of the pawl 1074 are both flat, the pawl 1074 will support and limit the position of the ratchet block 1073 on it, thereby supporting and limiting the position of the movable seat 106 together with the supporting keel 104. This allows the supporting keel 104 to be automatically limited after being pushed to the designated position by the personnel, without the need for manual limitation, thus improving work efficiency.

[0044] In some implementation schemes, such as Figure 4As shown, the lever assembly includes a shaft 205, a rocker 206, and a lever arm 204. The shaft 205 is symmetrically and rotatably mounted inside the support column 102. One side of the shaft 205 is connected to the rocker 206, which can abut against the bottom of the extrusion assembly. The other side of the shaft 205 is connected to the lever arm 204, which extends to the outside of the support column 102. This allows pulling the lever arm 204 to drive the rocker 206 to push the extrusion assembly around the shaft 205. In this embodiment, the length of the lever arm 204 is greater than the length of the rocker 206.

[0045] In some implementation schemes, such as Figure 2 and Figure 3 As shown, the extrusion assembly includes a top seat 201, a limiting plate 202, and a first locking member. The top of the telescopic upright 101 is connected to the limiting plate 202. The top seat 201, located inside the support column 102, is slidably sleeved on the outside of the limiting plate 202. The top of the top seat 201 has an inclined surface that abuts against the bottom conical surface 203 of the locking plate 107. The bottom inclined surface of the top seat 201 abuts against the rocker arm 206. The first locking member penetrates the bottom outer wall of the support column 102 and can lock the position of the top seat 201. Specifically, in this embodiment, the top seat 201 and the limiting plate 202 are telescopically connected, so that the limiting plate 202 can limit and guide the vertical extension and retraction of the top seat 201, thereby improving stability.

[0046] The top of the top seat 201 is a slope that corresponds to the bottom conical surface 203 of the locking plate 107. The sloped contact design allows the locking plate 107 to expand outward along both sides when the top seat 201 applies an upward pressing force to the locking plate 107, overcoming the spring force and releasing the movable seat 106.

[0047] In some implementation schemes, such as Figure 4 As shown, the first locking element includes a first slot 303 and a plug 304. The outer walls on both sides of the top seat 201 are provided with a plurality of first slots 303. The outer wall of the column is provided with an opening that corresponds to the first slot 303. The plug 304 can be slidably embedded in the opening of the outer wall of the column. The plug 304 can be inserted into the first slot 303 through the opening to lock the position of the top seat 201.

[0048] According to the release position and clamping position corresponding to the second slot at different height positions, when the insert block 304 is inserted into the first slot 303, combined with the release or clamping state of the locking plate 107, the top seat 201 can be fixed in the release position or clamping position. When long-term support is required, the top seat 201 can be locked in the clamping position to prevent accidental release. After demolding, it can also be locked in the release position for easy template recycling.

[0049] In some implementation schemes, such as Figure 5As shown, the buffer assembly 3 includes a connecting rod 301, a swing arm 302, a movable block 306, a damper 307, a second spring 308, and a second locking member. The connecting rod 301 is symmetrically hinged to both sides of the bottom of the supporting keel 104. The outer side of the column where the connecting rod 301 is located is adjacent to the outer side of the column where the lever arm 204 is located. The end of the connecting rod 301 away from the supporting keel 104 is hinged to the movable block 306. The outer wall of the support column 102 on the same side as the connecting rod 301 is hinged to the swing arm 302. The swing arm 302 has a second chamber inside. The damper 307 is installed inside the second chamber. The end of the damper 307 is connected to the movable block 306 that can slide inside the second chamber. The damper 307 is sleeved with a second spring 308. The second locking member that can lock the position of the movable block 306 is provided through the swing arm 302.

[0050] When the supporting keel 104 falls, it drives the connecting rod 301 to push the movable block 306 to compress the damper 307 and the second spring 308. The damper 307 consumes kinetic energy, and the second spring 308 releases elastic potential energy, which can effectively suppress impact vibration and avoid hard landing that could cause template deformation or loosening of connections. During normal support, the movable block 306 can be locked by inserting the bolt 309 into the second slot, making the buffer system rigid and not participating in the force. When demolding and falling, the bolt 309 is pulled out, releasing the buffer system and entering the buffer working state.

[0051] When it is necessary to push the supporting keel 104 upward, the worker can hold the swing arm 302 and push it upward, thereby converting the rotational motion of the swing arm 302 into the up-and-down motion of the supporting keel 104 through the connecting rod 301, thus saving effort by increasing the rotational path of the swing arm 302.

[0052] Furthermore, the second locking element includes a second slot and a bolt 309. The movable block 306 is provided with the second slot, and the swing arm 302 is provided with an opening that corresponds to the second slot. The bolt 309 can pass through the opening and be inserted into the second slot to lock the position of the movable block 306. Specifically, in this embodiment, the bolt 304 is connected to the swing arm 302 via a pull rope 305.

[0053] The pin-type locking mechanism, formed by the engagement of the bolt 309 with the second slot, allows for manual insertion and removal without tools.

[0054] When the supporting keel 104 needs to be pushed upward, the movable block 306 and the swing arm 302 are connected through the bolt 309. After the supporting keel 104 is pushed to the designated position, the bolt 309 is pulled out, so that the movable block 306 and the swing arm 302 are no longer fixedly connected. When the workers perform the quick disassembly of the template, the downward movement of the supporting keel 104 will apply a pushing force to the connecting rod 301. The connecting rod 301 will push the swing arm 302 to rotate downward until the swing arm 302 contacts the side of the support column 102 and can no longer rotate. At this time, the supporting keel 104 continues to push the connecting rod 301 to move downward, which in turn pushes the movable block 306 to move downward on the swing arm 302. The second spring 308 and the damper 307 will absorb and buffer the impact force, reduce the impact force and vibration of the template falling and falling, and improve stability.

[0055] The implementation principle of a device for quick dismantling of building formwork is as follows:

[0056] By providing multiple first slots 303, after the supporting keel 104 is pushed to a designated height using the swing arm 302, a mechanical self-locking mechanism is formed inside the support column through the cooperation of the pawl 1074 and the ratchet block 1073, fixing the support height of the supporting keel 104. Then, the plug 309 is pulled out, causing the movable block 306 to separate from the swing arm 302. Pushing the swing arm 302 downward pushes the plug 304 into the first slot 303, thus limiting the position of the top seat 201. When the operator needs to quickly disassemble, the swing arm 302 must first be pulled to use the pull rope 305 to separate the plug 304 from the first slot 303. The second spring 308 will provide resistance to prevent accidental contact.

[0057] When in use, the top support 103 supports the concrete structure through the curing board, and the supporting keel 104 supports the crossbeam. The formwork is located between the crossbeam and the concrete structure. When the concrete strength requirements meet the requirements of GB "Code for Acceptance of Construction Quality of Concrete Structures", the formwork can be removed early. At this point, the operator walks to the device, grasps the lever 204 and pulls it downwards, causing the rocker arm 206 to swing around the shaft 205. The length of the lever 204 is greater than that of the rocker arm 206, achieving the purpose of saving effort. This allows the operator to remove the template with less force, without the need for other tools, making it convenient for the operator to use. When the rocker arm 206 swings, it will push the top seat 201 upwards. When the top seat 201 contacts the locking plate 107, the tapered surface 203 at the bottom of the locking plate 107 will apply a diagonal pushing force to the locking plate 107, forcing the two locking plates 107 to overcome the elastic force of the first spring 1072 and open up. This pushes the two locking plates 107 simultaneously away from the movable seat 106, separating them from the movable seat 106 and releasing the locking plates 107 from restricting the position of the movable seat 106. At this time, the crossbeam and the template will automatically separate from the concrete structure due to their own weight, pushing the supporting keel 104 downwards, completing the quick removal of the template.

[0058] During the descent of the supporting keel 104, the connecting rod 301 pushes the movable block 306 into the second chamber within the swing arm 302. The movable block 306 compresses the damper 307 and the second spring 308, effectively absorbing the impact of the fall and preventing structural damage caused by free fall. If a buffered state needs to be locked, the position of the movable block 306 can be fixed by inserting the bolt 309 into the corresponding second slot.

[0059] When the workers use the rocker arm 206 to lift the top seat 201 for quick disassembly, and the supporting keel 104 uses the connecting rod 301 to push the swing arm 302 to fit against the support column 102, the swing arm 302 will contact and push the insert block 304 during rotation, thereby inserting the insert block 304 into the first slot 303, thus limiting the position of the top seat 201. At this time, the movable seat 106 will fall onto the top seat 201, and the top seat 201 will support the position of the movable seat 106 to improve stability. When resetting, push the swing arm 302 upward, and the pull rope 305 can be used to pull the insert block 304 out of the first slot 303, releasing the limitation on the position of the top seat 201.

[0060] For sections that have been dismantled, the formwork and other reusable components can be promptly recycled to free up space for subsequent construction.

[0061] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
