[0036] See Figures 1 to 3The formwork reinforcement device for building frame columns according to an embodiment of the present invention includes: a support back plate 101, a first reinforcement component, a second reinforcement component, and a third reinforcement component; wherein, a lifting mechanism is provided on the support back plate 101, and a set of the first reinforcement components is provided on one side of the lifting mechanism; a set of the second reinforcement components is slidably connected to both ends of the set of the first reinforcement components in the horizontal direction; each set of the second reinforcement components includes a plurality of second reinforcement rods 205 spaced apart in the vertical direction, and a plurality of telescopic connecting rods 2 are slidably connected between any two adjacent second reinforcement rods 205. 06; A third reinforcing component is inserted at one end of the two sets of second reinforcing components away from the first reinforcing component; the third reinforcing component is arranged opposite to the first reinforcing component; the first reinforcing component, the second reinforcing component, and the third reinforcing component form a frame structure to reinforce the frame column template 100; the two ends of the second reinforcing component and the third reinforcing component are provided with compression mechanisms to apply compression force to the third reinforcing component, thereby enclosing and clamping the frame column template 100 in the frame structure formed by the three components.

[0037] Specifically, a groove is formed in the middle of the support back plate 101 to provide a placement channel for the frame column template 100. A handle is provided on one side of the support back plate 101, and the handle can be an inverted U-shaped structure. Four universal casters 102 with brakes are movably installed on the bottom side of the support back plate 101, and two fixing frames 200 are fixedly installed on the top side of the support back plate 101. The two fixing frames 200 are equipped with a lifting mechanism, which includes a lifting motor 201, a lifting screw 202, and a lifting rod 203. The output end of the lifting motor 201 is connected to one end of the lifting screw 202, and the other end of the lifting screw 202 is threadedly connected to the lifting rod 203. The lifting rod 203 of the lifting mechanism is connected to a first reinforcing rod 204 located at the top of the first reinforcing assembly, so as to drive the first reinforcing rod 204 to drive the other first reinforcing rods 204 to move up and down.

[0038] Two lifting motors 201 are fixedly installed on the bottom side of the support back plate 101. Lifting screws 202 are fixedly installed on the output end of each of the two lifting motors 201. Both lifting screws 202 are rotatably installed on the support back plate 101. Lifting rods 203 are threadedly installed on each of the two lifting screws 202. The two lifting rods 203 are slidably installed on the two fixed frames 200 respectively.

[0039] The first, second, and third reinforcement components each include a plurality of first reinforcement rods 204, a plurality of second reinforcement rods 205, and a plurality of third reinforcement rods 401. The first reinforcement rods 204, second reinforcement rods 205, and third reinforcement rods 401 located at the bottom layer are all disposed on the upper surface of the support back plate 101.

[0040] The third reinforcement component includes a plurality of third reinforcement rods 401 arranged horizontally, with each third reinforcement rod 401 spaced apart in the vertical direction. One end of each third reinforcement rod 401 is provided with a limiting part to prevent it from detaching from the second reinforcement component.

[0041] The inner wall of the second reinforcing rod 205 is provided with an insertion hole 400, and an extrusion block 402 is slidably connected in the insertion hole 400. One end of the extrusion block 402 is in contact with one side of the third reinforcing rod 401, and is used to apply a pushing force to the third reinforcing rod 401 under the action of external force.

[0042] In this embodiment, each of the first reinforcing rods 204, second reinforcing rods 205, and third reinforcing rods 401 is arranged horizontally to form a frame mechanism to fit the frame column template 100, and each of the first reinforcing rods 204, second reinforcing rods 205, and third reinforcing rods 401 is arranged at intervals in the vertical direction. Two sets of second reinforcing components are arranged opposite each other, and the first reinforcing components and the third reinforcing components are arranged opposite each other, forming a square movable frame.

[0043] Both sets of second and third reinforcement components are equipped with compression mechanisms at the connection points to push the third reinforcement component toward the frame column template 100 and make it fit tightly against it.

[0044] The extrusion mechanism includes an extrusion block 402 and a push screw 403 connected to each other; wherein, the extrusion block is slidably connected to an insertion hole 400 opened in the inner wall of the second reinforcing rod 205; one end of the push screw 403 passes through the end of the second reinforcing rod 205 and is connected to an internal thread gear 404 provided on the outer side wall of the end of the second reinforcing rod 205, and the other end of the push screw 403 is connected to the extrusion block 402.

[0045] See Figure 5 More specifically, the internal threaded gear 404 has a first annular groove 412, and a first limiting ring 413 is rotatably connected in the first annular groove 412. The first limiting ring 413 is fixedly installed on one side of the second reinforcing rod 205, and the internal threaded gear 404 can rotate on the first limiting ring 413 through the first annular groove 412 to prevent the internal threaded gear 404 from deviating.

[0046] As can be clearly seen from the above, the reinforcement device for the building frame column formwork 100 provided in this embodiment uses two sets of second reinforcement components slidably connected to the first reinforcement component, causing the second reinforcement components to move inward and adhere to both sides of the frame column formwork 100; the end of the second reinforcement component is provided with a pressing mechanism, which pushes the third reinforcement rod 401 to adhere to the other side of the frame column formwork 100, so that the frame column formwork 100 is surrounded and reinforced by the third reinforcement component, the first reinforcement component, and the two sets of second reinforcement components, making the reinforcement process simple and quick, avoiding workers from repeatedly tightening and loosening screws or climbing ladders for installation, thereby improving construction efficiency; the lifting mechanism controls the first reinforcement component to drive the second and third reinforcement components to different heights, so that the height of the reinforcement device can be adjusted according to the height of the frame column formwork 100 at the construction site, greatly improving the applicability of the device.

[0047] See Figure 1 and Figure 4 In the above embodiment, the first reinforcement component includes: a plurality of first reinforcement rods 204 arranged in a horizontal direction; wherein, each of the first reinforcement rods 204 is arranged at intervals in a vertical direction along one side of the lifting mechanism, and a guide groove 207 is provided on the inner wall of the first reinforcement rod 204, and two guide sliders 208 are slidably arranged in the guide groove 207, and the two guide sliders 208 are respectively connected to one end of the two second reinforcement rods 205.

[0048] Specifically, the inward-facing portion of the first reinforcing rod 204 has a guide groove 207, which restricts the movement direction of the guide slider 208. The two guide sliders 208 are respectively connected to the two second reinforcing rods 205 at both ends, so that when the guide sliders 208 move, they drive the two second reinforcing rods 205 to move relative to each other or away from each other, thereby achieving clamping of the frame column template 100.

[0049] Furthermore, continue to combine Figure 1 and Figure 2 One of the first reinforcing rods 204 is provided with a clamping motor 300 on one side. The output end of the clamping motor 300 is provided with a positive and negative threaded rod 301. The positive and negative threaded rod 301 is rotatably connected to two guide sliders 208 on the first reinforcing rod 204.

[0050] Specifically, a clamping motor 300 and a forward / reverse threaded rod 301 can be installed at one end of the first reinforcing rod 204 located on the surface of the support back plate 101, so that the rotational motion is converted into the linear motion of the two guide sliders 208 through the forward / reverse threaded rod 301. When the two second reinforcing rods 205 located at the bottom slide along the first reinforcing rod 204, they will drive the movement of the second reinforcing rods 205 on each layer above them through the telescopic connecting rod 206.

[0051] In practice, the output end of the clamping motor 300 is fixedly equipped with a positive and negative threaded rod 301. The positive and negative threaded rod 301 is rotatably mounted on a corresponding first reinforcing rod 204. The positive and negative threaded rod 301 is threadedly mounted on two corresponding guide sliders 208. The output end of the clamping motor 300 will drive the positive and negative threaded rod 301 to rotate. The rotating positive and negative threaded rod 301 can drive the two corresponding guide sliders 208 to move closer to each other or further away from each other.

[0052] See Figure 1 , Figure 2 , Figure 5 and Figure 7 In the above embodiments, each of the second reinforcing rods 205 is provided with a plurality of sliding grooves 209. The sliding grooves 209 on any two adjacent second reinforcing rods 205 are arranged in a one-to-one correspondence. Each telescopic link 206 is slidably installed in the corresponding sliding grooves 209 on any two adjacent reinforcing rods, and the telescopic links 206 on any two adjacent layers are staggered.

[0053] Specifically, each second reinforcing rod 205 has a sliding groove 209 arranged vertically, and the sliding groove 209 can be arc-shaped, preferably semi-arc-shaped. The limiting part at the end of the corresponding telescopic link 206 can be semi-arc-shaped to engage with the sliding groove 209. In this embodiment, to avoid interference between the telescopic links 206 of adjacent layers, the telescopic links 206 are staggered in adjacent layers.

[0054] In practice, the telescopic link 206 is slidably installed in a corresponding sliding groove 209. As the second reinforcing rod 205 rises and falls, it slides along the telescopic link 206 through the sliding groove 209. When it reaches the bottom, the second reinforcing rod 205 pulls the telescopic link 206 to move. The continuously moving telescopic link 206 then slides within the sliding groove 209 on another second reinforcing rod 205.

[0055] The movement will eventually pull the second reinforcing rod 205 of the adjacent layer to move.

[0056] See Figure 2 , Figure 4 and Figure 6In the above embodiments, a linkage rod 407 is provided vertically on the side of each of the two sets of second reinforcing components near the third reinforcing component. Multiple connecting plates 405 are provided on the same side of each set of second reinforcing rods 205. The linkage rod 407 passes through each connecting plate 405 and is movably connected to each connecting plate 405. A first bevel gear 406 is provided on the upper surface of the connecting plate 405. The first bevel gear 406 is slidably connected to the linkage rod 407. A linkage gear 408 that meshes with the internal thread gear 404 is provided on the same side of the second reinforcing rod 205. A second bevel gear 409 that meshes with the first bevel gear 406 is provided on one side of the linkage gear 408.

[0057] Specifically, the linkage rod 407 is a vertical rod, and each set of second reinforcing rods 205 has a corresponding connection hole. The linkage rod 407 passes through each connection hole at once.

[0058] Two vertical slide grooves 410 are provided on the linkage rod 407. Vertical sliders 411 are slidably installed in both vertical slide grooves 410. Both vertical sliders 411 are fixedly installed on the inner wall of the first conical tooth. The first conical tooth will drive the two vertical sliders to slide in the two vertical slide grooves 410 on the linkage rod 407 respectively, so that the first conical tooth can follow the rise and fall.

[0059] A linkage motor 416 is provided at the bottom of the connecting plate 405 located at the bottom. The output end of the linkage motor 416 is connected to the linkage rod 407. Correspondingly, a first bevel gear 406 is provided above the connecting hole on each connecting plate 405 in each group. The first bevel gear 406 can be slidably connected to the linkage rod 407 through a slider. A second bevel gear 409 is provided on this side of the second reinforcing rod 205 to mesh with the first bevel gear 406. A linkage gear 408 is provided on one side of the second bevel gear 409. The two are coaxially arranged. The linkage gear 408 meshes with the internal thread gear 404 on one side of it to drive the push screw 403 to rotate, thereby driving the extrusion block 402 to apply extrusion force to the third reinforcing rod 401.

[0060] Furthermore, two vertical grooves 410 are provided on the linkage rod 407, and vertical sliders are slidably installed in both vertical grooves 410. Both vertical sliders are connected to the inner wall of the first conical toothed rod 406.

[0061] Furthermore, a second annular groove 414 is formed on the first conical tooth, and a second limiting ring 415 is rotatably connected within the second annular groove 414. The second limiting ring 415 is fixedly installed on the connecting plate 405. When the first conical tooth rotates, it will rotate through the second annular groove 414 and on the second limiting ring 415, preventing the first conical gear 406 from deviating.

[0062] The working principle of this invention is as follows:

[0063] When the lifting motor 201 is turned on, it drives the lifting screw 202 to rotate. The rotating lifting screw 202 drives the lifting rod 203 to slide on the fixed frame 200. The lifting rod 203 drives the corresponding first reinforcing rod 204 to rise and fall. The first reinforcing rod 204 drives the corresponding two second reinforcing rods 205 to rise and fall. While the two second reinforcing rods 205 are rising and falling, they slide on the telescopic connecting rod 206 through the sliding groove 209. When they slide to the bottom, the second reinforcing rod 205 pulls the telescopic connecting rod 206 to move. The continuously moving telescopic connecting rod 206 slides in the sliding groove 209 on another second reinforcing rod 205, eventually pulling the second reinforcing rod 205 of the adjacent layer to move. This process is repeated, so that multiple second reinforcing rods 205 can be raised and lowered to unfold or retract.

[0064] When reinforcing the frame column template 100, the linkage motors 416 on both sides can be turned on first. The output end of the linkage motor 416 will drive the linkage rod 407 to rotate. The rotating linkage rod 407 will drive the first conical tooth to rotate through the cooperation of the vertical slide groove 410 and the vertical slider. The continuously rotating first conical tooth will drive the second conical tooth to rotate, and the second conical tooth will drive the linkage gear 408 to rotate. This will cause the rotating linkage gear 408 to drive the internal thread gear 404 to rotate. When the internal thread gear 404 rotates, it will drive the push screw 403 to move horizontally. The horizontally moving push screw 403 will drive the extrusion block 402 to slide in the insertion hole 400. By setting multiple first conical teeth on the linkage rod 407, the position of multiple extrusion blocks 402 can be controlled simultaneously.

[0065] First, adjust the position of the extrusion block 402 away from the third reinforcing rod 401. Then, pull all the third reinforcing rods 401 out of their corresponding insertion holes 400, ensuring there are no obstructions in front of the device. Next, push the device towards the frame column template 100, ensuring the first reinforcing rod 204 is flush against one side of the frame column template 100. There are second reinforcing rods 205 on both sides of the frame column template 100. Then, reinsert the third reinforcing rods 401 back into their corresponding insertion holes 400. Next, based on the height of the frame column template 100, activate the lifting motor 201 to control the raising and lowering of multiple second reinforcing rods 205. After height adjustment, activate the clamping motor 300. The output of the clamping motor 300 will drive the positive and negative threaded rods 301 to rotate. The rotating positive and negative threaded rods 301 can drive the corresponding two guide sliders 208 to move closer or further apart. The moving guide sliders 208 will move in the guide groove. The sliding within 207 restricts the movement direction of the guide slider 208. The two guide sliders 208 that continue to move closer will cause the two second reinforcing rods 205 to move closer to each other. During the horizontal movement of the second reinforcing rods 205, the sliding groove 209 and the telescopic connecting rod 206 will drive the second reinforcing rods 205 of the adjacent layer to move. By staggering the sliding grooves 209 and the telescopic connecting rods 206 on multiple second reinforcing rods 205, multiple second reinforcing rods 205 can move simultaneously, so that the second reinforcing rods 205 on both sides can be close to both sides of the frame column template 100. During the upward movement of the second reinforcing rods 205, the connecting plate 405 will rise, and the rising connecting plate 405 will drive the first conical tooth to rise. The first conical tooth will then drive the two vertical sliders to slide in the two vertical sliding grooves 410 on the linkage rod 407, so that the first conical tooth can follow the rise and play a role when the height of the second reinforcing rod 205 changes.

[0066] Then, two linkage motors 416 are turned on to control the movement of the extrusion block 402 and extrusion of the third reinforcing rod 401, pressing the third reinforcing rod 401 against the frame column template 100. Finally, the frame column template 100 is surrounded and reinforced by the third reinforcing rod 401, the first reinforcing rod 204 and the two second reinforcing rods 205.

[0067] In summary, the formwork reinforcement device for building frame columns provided by this invention has the following beneficial effects:

[0068] By incorporating clamping motors and linkage motors, the system allows for the pushing of the support backplate to bring the first reinforcing rod close to one side of the frame column template. At this point, the second reinforcing rods are positioned on both sides of the template. Then, the third reinforcing rods are inserted into their corresponding holes. Activating the lifting motors controls the upward unfolding of multiple second reinforcing rods. Afterward, the clamping motors move the second reinforcing rods on both sides inward to close to the sides of the frame column template. Two linkage motors control the pressing blocks to push the third reinforcing rods close to the other side of the template. At this point, the frame column template is reinforced by the third reinforcing rod, the first reinforcing rod, and two second reinforcing rods. This simple and quick reinforcement process avoids the need for workers to repeatedly tighten and loosen screws or climb ladders, thus improving construction efficiency.

[0069] By using a lifting motor, the second reinforcing rod can be raised to different heights, which can be adjusted according to the height of the frame column formwork at the construction site, thereby improving the applicability of the device.

[0070] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
