[0028] 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.
[0029] Combination Figures 1 to 5 As 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.
[0030] 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.
[0031] The telescopic vertical rod 101 is used as a fixed base support, the support column 102 can slide up and down along the telescopic vertical rod 101, the height of the jacking support 103 is adjusted, and the jacking support 103 can mainly support the concrete structure of the maintenance plate top column in the embodiment. The sliding assembly is used to drive the supporting keel 104 to move, so as to adjust the supporting height of the supporting keel 104, and the supporting keel 104 can support the beam formwork. When the supporting keel 104 is quickly detached, it will fall quickly, and if there is no buffer, it will produce a violent impact, which is easy to cause structural fatigue or deformation of the formwork. In the embodiment, the buffer assembly 3 is used to absorb kinetic energy, slow down the falling speed, and reduce the risk of collapse.
[0032] In some embodiments, as shown in Figure 2 The inner top of the support column 102 is provided with a movable groove 108, the movable groove 108 is connected with the sliding block 105, the bottom of the sliding block 105 is connected with the movable seat 106, the inner bottom of the support column 102 is provided with a first cavity, the inside of the first cavity is provided with an elastic clamping assembly and a pressing assembly, the elastic clamping assembly is symmetrically arranged on both sides of the movable seat 106, the clamping end of the elastic clamping assembly corresponds to the circumferential side of the movable seat 106, the pressing assembly is located below the movable seat 106, the inside of the support column 102 is symmetrically hinged with a lever assembly, the output end of the lever assembly corresponds to the bottom of the pressing assembly, and the lever assembly can drive the pressing assembly to slide and press the elastic clamping assembly.
[0033] In the embodiment, the movement track of the movable groove 108 and the sliding block 105 is matched, the movable groove 108 can limit the movement range of the sliding block 105, not only can ensure that the vertical movement of the sliding block 105 does not deviate, but also can limit the falling distance of the supporting keel 104, so that the supported beam formwork will not directly fall on the ground and be damaged.
[0034] In some embodiments, as shown in Figure 3 The elastic clamping assembly includes a locking plate 107, a limiting rod 1071 and a first spring 1072, a group of locking plates 107 are symmetrically arranged on both sides of the movable seat 106, a plurality of limiting rods 1071 are slidably arranged on the locking plate 107, the limiting rods 1071 are connected to the inner wall of the support column 102 at both ends, the first spring 1072 is sleeved on the limiting rod 1071 between the group of locking plates 107, and the bottom of the group of locking plates 107 is provided with a conical surface 203 which can abut against the pressing assembly.
[0035] The position of the locking plate 107 is limited and guided by the limiting rod 1071, so that it can only move axially along the limiting rod 1071 stably. The first spring 1072 applies a pulling force to the locking plate 107 in the direction of the movable seat 106 by using its elasticity. When the extrusion assembly moves downward to disengage from the locking plate 107, the first spring 1072 will pull the locking plate 107 due to the disappearance of resistance, so that it contacts the movable seat 106, thereby limiting the position of the movable seat 106 together with the supporting keel 104. The first spring 1072 always pushes the locking plate 107 inward, and once the extrusion is removed, it automatically restores the clamping state. Without manual intervention, it can complete the relocking and be suitable for repeated use scenarios.
[0036] Further, as shown in Figure 3 The inner wall of the locking plate 107 is arrayed with a plurality of pawls 1074, the pawls 1074 are hinged to the inner wall of the locking plate 107, the upper surface of the pawl 1074 is planar, the lower surface of the pawl 1074 is beveled, the movable seat 106 is provided with a plurality of ratchet blocks 1073 towards the outer wall of the locking plate 107, the upper surface of the ratchet block 1073 is beveled, the lower surface of the ratchet block 1073 is planar, the pawl 1074 and the ratchet block 1073 can abut each other, the locking plate 107 is further provided with an elastic member 1075 capable of abutting the pawl 1074, the elastic member 1075 can provide a restoring force to the pawl 1074 after being extruded. Specifically, the elastic member 1075 in the embodiment includes but is not limited to profiled springs, rubber strips, etc.
[0037] The pawl 1074 and the ratchet block 1073 cooperate to form a mechanical self-locking mechanism. When the movable seat 106 moves upward, the bevel guides the locking plate 107 to expand outward, but the first spring 1072 pulls back to keep clamping. When the movable seat 106 accidentally slips downward, the flat surface abuts to prevent backsliding, preventing loosening, and playing a role in anti-skid under the bearing state, ensuring construction safety.
[0038] When the device is installed and used, the supporting keel 104 can be pushed to move upward to contact the cross beam and press the formwork on the concrete structure to complete the stable support. When the supporting keel 104 moves upward, a plurality of ratchet blocks 1073 are driven 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 provided with inclined surfaces, the pawl 1074 is hingedly connected with the locking plate, and the pawl 1074 has a certain moving space at the top. During the upward movement of the ratchet block 1073, an inclined thrust is generated to the pawl 1074 when the ratchet block 1073 contacts the pawl 1074, so as to rotate and push away the pawl 1074. When the pawl 1074 is pushed away, the elastic member 1075 is compressed to accumulate potential energy. After the ratchet block 1073 passes the pawl 1074, the elastic potential energy accumulated by the elastic member is released to push the pawl 1074 back to the original position. Since the lower surface of the ratchet block 1073 and the upper surface of the pawl 1074 are both provided with flat surfaces, the pawl 1074 supports and limits the position of the ratchet block 1073, thereby supporting and limiting the position of the movable seat 106 and the supporting keel 104, so that the supporting keel 104 is self-limited after being pushed to the specified position by the personnel, without the need for manual limitation, thereby improving the work efficiency.
[0039] In some embodiments, as shown in Figure 4 The lever assembly includes a shaft 205, a flap 206 and a labor-saving arm 204. The shaft 205 is symmetrically and rotatably installed inside the support column 102. The shaft 205 is connected with the flap 206 which can abut against the bottom of the extrusion assembly. The other side of the shaft 205 is connected with the labor-saving arm 204 which extends to the outside of the support column 102. Pulling the labor-saving arm 204 can drive the flap 206 to push the extrusion assembly with the shaft 205 as the axis. In this embodiment, the length of the labor-saving arm 204 is greater than the length of the flap 206.
[0040] In some embodiments, as shown in Figure 2 and Figure 3 The extrusion assembly includes a top seat 201, a limiting plate 202 and a first locking member. The top end of the telescopic vertical rod 101 is connected with the limiting plate 202. The limiting plate 202 is externally sleeved with the top seat 201 which is located inside the support column 102. The top of the top seat 201 is provided with an inclined surface which can abut against the bottom conical surface 203 of the locking plate 107. The bottom inclined surface of the top seat 201 corresponds to and abuts against the flap 206. The bottom outer wall of the support column 102 is penetrated by the first locking member which can lock the position of the top seat 201. Specifically, in this embodiment, the top seat 201 is telescopically connected with the limiting plate 202, so that the limiting plate 202 can limit and guide the telescopic movement of the top seat 201 in the vertical direction, thereby improving the stability.
[0041] The top of the top base 201 is a slope corresponding to the bottom tapered surface 203 of the locking plate 107, and the slope is designed to abut. When the top base 201 exerts an upward extrusion force on the locking plate 107, the slope forces the locking plate 107 to expand outward on both sides, overcoming the spring force, and releasing the movable seat 106.
[0042] In some embodiments, as shown in Figure 4 The first locking member includes a first slot 303 and a plug 304. The two side walls of the top base 201 are provided with a plurality of first slots 303, and the outer wall of the column is provided with openings corresponding to the first slots 303. The plug 304 is slidably arranged in the openings of the outer wall of the column, and the plug 304 can be inserted into the first slot 303 through the openings to lock the position of the top base 201.
[0043] According to the second slot corresponding to the release position and the clamping position at different height positions, when the plug 304 is inserted into the first slot 303, the top base 201 can be fixed at the release position or the clamping position in combination with the release or clamping state of the locking plate 107. When long-term support is needed, the top base 201 is locked at the clamping position to prevent accidental release. After the formwork is removed, the top base 201 can also be locked at the release position for convenient formwork recovery.
[0044] In some embodiments, as shown in Figure 5 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 bottom of the supporting keel 104 is symmetrically hinged with the connecting rod 301 on both sides. The connecting rod 301 is adjacent to the outer side of the column where the force-saving arm 204 is located. The end of the connecting rod 301 away from the supporting keel 104 is hinged with the movable block 306. The outer wall of the column on the same side of the connecting rod 301 is hinged with the swing arm 302. The swing arm 302 is internally provided with a second cavity. The second cavity is internally provided with the damper 307. The end of the damper 307 is connected with the movable block 306 which can slide in the second cavity. The damper 307 is externally provided with the second spring 308. The swing arm 302 is provided with the second locking member which can lock the position of the movable block 306.
[0045] When the supporting keel 104 falls, it will drive 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 causing formwork deformation or loose connection. When normally supporting, the plug 309 is inserted into the second slot to lock the movable block 306, so that the buffer system is rigid and does not participate in force bearing. When removing the formwork, the plug 309 is pulled out to release the buffer system and enter the buffer working state.
[0046] When the supporting keel 104 needs to be pushed upward, the worker can hold the swing arm 302 and push it upward, thereby converting the rotary motion of the swing arm 302 into the up-down motion of the supporting keel 104 through the connecting rod 301, and achieving the purpose of saving labor by increasing the rotary path of the swing arm 302.
[0047] Further, the second locking member comprises a second slot and a plug 309, the movable block 306 is provided with the second slot, the swing arm 302 is provided with an opening corresponding to the second slot, and the plug 309 can be inserted through the opening into the second slot to lock the position of the movable block 306. Specifically, in the embodiment, the plug 304 is connected to the swing arm 302 through the pull rope 305.
[0048] By adopting the plug-in type locking formed by the cooperation of the plug 309 and the second slot, the plug can be manually inserted and pulled out without tools.
[0049] When the supporting keel 104 needs to be pushed upward, the movable block 306 and the swing arm 302 are connected through the plug 309, and after the supporting keel 104 is pushed to the specified position, the plug 309 is pulled out, so that the movable block 306 and the swing arm 302 are in a state of disconnection. When the worker performs the quick disassembly of the template, the downward movement of the supporting keel 104 will exert a pushing force on 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 surface of the support 102, so that it cannot continue to rotate. At this time, the supporting keel 104 continues to push the connecting rod 301 to move downward, thereby pushing the movable block 306 to move downward on the swing arm 302, and the second spring 308 and the damper 307 can absorb and buffer the impact force, reduce the impact force and vibration of the falling template, and improve the stability.
[0050] The implementation principle of the device for quick disassembly of the building template according to the embodiment is as follows: By being provided with a plurality of first slots 303, after the supporting keel 104 is pushed to the specified height by the swing arm 302, the mechanical self-locking mechanism is formed inside the support by the cooperation of the pawl 1074 and the ratchet block 1073, the supporting height of the supporting keel 104 is fixed, the plug 309 is pulled out to separate the movable block 306 from the swing arm 302, the swing arm 302 is pushed downward to push the plug 304 into the first slot 303, and the position of the top seat 201 is limited. When the worker needs to quickly disassemble, the swing arm 302 needs to be pulled to separate the plug 304 from the first slot 303 through the pull rope 305, and the second spring 308 provides resistance to achieve the purpose of preventing accidental touch.
[0051] When in use, the top support 103 supports the concrete structure by the maintenance plate, the cross beam is supported by the supporting keel 104, and the formwork is located between the cross beam and the concrete structure. When the concrete strength meets the requirements of the GB "Concrete Structure Engineering Construction Quality Acceptance Specification", the formwork can be early removed. At this time, the personnel go to the front of the device, hold the labor-saving arm 204 with their hands and pull it down, so that it drives the swing plate 206 to swing around the shaft rod 205 as the axis. The length of the labor-saving arm 204 is greater than that of the swing plate 206, so that the purpose of saving labor is achieved, so that personnel can use smaller force to achieve the removal of the formwork, and no other tools are needed to assist, which is convenient for personnel to use. When the swing plate 206 swings, the top seat 201 is lifted upward, and when the top seat 201 contacts the locking plate 107, the locking plate 107 is subjected to an inclined thrust by the conical surface 203 at the bottom of the locking plate 107, so that the two locking plates 107 are forced to open against the elastic force of the first spring 1072, so that the two locking plates 107 are pushed away from the movable seat 106 at the same time, so that they are separated from the movable seat 106 and are staggered, and the limitation of the position of the movable seat 106 by the locking plate 107 is released. At this time, the cross beam and the formwork will automatically separate from the concrete structure due to the self-weight, the supporting keel 104 is pushed downward, and the fast removal of the formwork is completed.
[0052] During the falling process of the supporting keel 104, the connecting rod 301 pushes the movable block 306 into the second cavity in the swing arm 302, the movable block 306 compresses the damper 307 and the second spring 308, and the falling impact is effectively absorbed, so that the structure damage caused by free fall is avoided. If the buffer state needs to be locked, the position of the movable block 306 can be fixed by inserting the plug 309 into the corresponding second insertion slot.
[0053] When the personnel use the swing plate 206 to lift the top seat 201 for fast removal, the supporting keel 104 pushes the swing arm 302 to be in close contact with the support column 102, and the swing arm 302 will contact and push the plug 304 during the rotation process, so that the plug 304 is inserted into the first insertion slot 303, and the position of the top seat 201 is limited. At this time, the movable seat 106 will fall onto the top seat 201, and the position of the movable seat 106 is supported by the top seat 201, so that the stability is improved. When the reset is performed, the swing arm 302 is pushed upward, and the plug 304 is pulled out of the first insertion slot 303 by the pull rope 305, so that the position of the top seat 201 is released.
[0054] For the part that has been removed, the formwork and other reusable parts can be recycled in time to make room for subsequent construction.
[0055] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
