Description
Technical Field
[0001] The present invention relates to the technical field of concrete pouring, and particularly relates to a sealing and reinforcement device for a pouring column formwork. Background Art
[0002] With the accelerating urbanization process and the continuous development of urban housing construction, when constructing a housing building, precast beams and columns are generally used for support to build the initial framework of the building.
[0003] During the process of pouring and constructing the beams and columns, in order to maintain the stability and vertical state of the beams and columns, it is necessary to reinforce the pouring column to prevent the pouring column from tilting during the forming process. Existing devices generally reinforce the outer circle of the pouring column by using reinforcing plates and reinforcing bars. During the reinforcement process, it is difficult for the reinforcing plates to be advanced synchronously, which will lead to inconsistent travel distances of the reinforcing plates, resulting in gaps between the reinforcing plates and the pouring column and unable to fit tightly, reducing the reinforcement effect. At the same time, when reinforcing a relatively high pouring column, the reinforcement height of the existing device is relatively fixed and it is difficult to be quickly extended.
[0004] Therefore, in view of the above problems, a sealing and reinforcement device for a pouring column formwork that can be advanced synchronously and move closely, and at the same time can quickly extend the reinforcement height is now developed. Summary of the Invention
[0005] In order to overcome the shortcomings that it is difficult for the reinforcing plates of the existing device to be advanced synchronously, which will lead to inconsistent travel distances of the reinforcing plates, resulting in the inability to fit tightly between the reinforcing plates and the pouring column, and at the same time, it is difficult to be quickly extended when reinforcing a relatively high pouring column, the present invention provides a sealing and reinforcement device for a pouring column formwork that can be advanced synchronously and move closely, and at the same time can quickly extend the reinforcement height.
[0006] The technical implementation plan of the present invention is as follows: A sealing and reinforcement device for a pouring column formwork includes a chassis assembly, a bidirectional threaded sleeve rod, side plates, a positioning mechanism, and an extension mechanism. Symmetrically distributed bidirectional threaded sleeve rods are rotatably connected to the upper sides of the front, rear, left, and right parts of the chassis assembly.

[0008] More preferably, the expansion mechanism includes a first guide frame, a rack, a gear, a pull rope, a winding rod, a slide plate, a guide rod, and an expansion plate.

First bidirectional lead screws are connected to the second cross plates. Symmetric first cross plates for clamping and fixing the side plates are slidably connected between the adjacent left and right first bidirectional lead screws and the adjacent front and rear first bidirectional lead screws. Nuts for enhancing the clamping and fixing effect are connected to the first bidirectional lead screws in a threaded manner. Spacer blocks that can be pushed by the adjacent nuts are connected to the first cross plates.
[0010] More preferably, a fixing mechanism is further included. The fixing mechanism includes a second bidirectional lead screw, a second guide frame, a sliding clamping frame, and a clamping rod. Second bidirectional lead screws are rotatably connected to the non-adjacent sides of the front and rear expansion plates.

In the present invention, the output shaft of the servo motor drives the adjacent pulley assemblies to operate, so that the threaded rods rotate synchronously, and the chucks push the corresponding side plates to move synchronously, avoiding inconsistent travel distances of the side plates, which may cause the side plates not to fully fit the pouring column and affect the reinforcement effect.
[0015] 2. In the present invention, the output shaft of the servo motor drives the threaded rod to rotate, so that the gear drives the rack to slide downward, and then the sliding plate pushes the expansion plate upward to turn over, extending the reinforcement height of the side plate, so as to reinforce and stabilize pouring columns of different heights.
[0016] 3. In the present invention, the rotating nut pushes the cushion block to slide, so that the first cross plates slide toward the side plate, and then the side plate is reinforced and stabilized, improving the reinforcement effect of the side plate on the pouring column.
[0017] 4. In the present invention, the sliding bracket is clamped with the adjacent clamping rod, so that the four expansion plates enter the locked state. After the expansion plates enter the locked state, the stability is enhanced, and the accidental turning over of the expansion plates during the reinforcement process can be avoided.

Detailed implementation manners
[0027] The following is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention accordingly.
[0028] A sealing and reinforcement device for a casting column formwork, as Figure 1 and Figure 2 shown, includes a chassis assembly 1, a bidirectional threaded sleeve rod 2, side plates 3, a positioning mechanism 4 and an expansion mechanism 5. The chassis assembly 1 includes a fixed chassis and a rotating chassis. The rotating chassis is rotatably connected to the front side of the fixed chassis. On the upper sides of the four parts of the front, rear, left and right of the chassis assembly 1, symmetrically distributed bidirectional threaded sleeve rods 2 are rotatably connected. Between two adjacent bidirectional threaded sleeve rods 2 on the same side, side plates 3 are rotatably connected. A positioning mechanism 4 is provided on the chassis assembly 1, and an expansion mechanism 5 is provided on the side plates 3.
[0029] It should be noted that when constructing a casting column, in order to maintain the stability and verticality of the casting column, this device can be used to reinforce and stabilize the casting column. The positioning mechanism 4 controls the side plates 3 to move synchronously, so that the side plates 3 move synchronously to fit and reinforce the casting column. Then, according to the height of the casting column, the expansion mechanism 5 is used for extension, so as to stably reinforce casting columns of different heights. It should be particularly noted that when the side plates 3 reinforce and stabilize the casting column, the bidirectional threaded sleeve rods 2 can support and stabilize the side plates 3.
[0030] AsFigure 1 and Figure 3 As shown in Figure 3 , the positioning mechanism 4 includes a fixed frame 41, a servo motor 42, a pulley assembly 43, a threaded rod 44, and a chuck 45. Fixed frames 41 are bolted to the upper sides of the front, rear, left, and right parts of the chassis assembly 1. Servo motors 42 are bolted to the fixed frames 41. Threaded rods 44 are threadedly connected to the tops of the servo motors 42. Chucks 45 are connected to the adjacent sides of the threaded rods 44. The circular chucks 45 can be clamped to the adjacent side plates 3. Pulley assemblies 43 are connected between the opposite ends of the threaded rods 44 and the output shafts of the corresponding servo motors 42.
[0031] It should be noted that when sealing and strengthening the cast column, the side plates 3 need to be synchronously attached to the four sides of the cast column for strengthening. At this time, to avoid inconsistent travel distances of the side plates 3, the servo motors 42 can be directly started. The output shafts of the servo motors 42 will start to rotate, driving the adjacent pulley assemblies 43 to operate, and then causing the corresponding threaded rods 44 to start rotating. As the threaded rods 44 start rotating, the threaded rods 44 will drive the adjacent chucks 45 to move towards each other, pushing the side plates 3 towards each other, enabling the side plates 3 to move synchronously and attach to the cast column, thereby strengthening the cast column by attachment and allowing the cast column to be quickly formed. After the operation is completed, the servo motors 42 can be turned off. In summary, the output shafts of the servo motors 42 drive the adjacent pulley assemblies 43 to operate, causing the threaded rods 44 to rotate synchronously and the chucks 45 to push the corresponding side plates 3 to move synchronously, avoiding inconsistent travel distances of the side plates 3, which may cause the side plates 3 to not fully attach to the cast column and affect the strengthening effect.
[0032] As Figure 1 and Figure 4 shown in Figure 4 , the extension mechanism 5 includes a first guide frame 51, a rack 52, a gear 53, a pull rope 54, a winding rod 55, a slide plate 56, a guide rod 57, and an extension plate 58. First guide frames 51 are bolted symmetrically up and down on the non - adjacent sides of the side plates 3. Racks 52 are slidably connected between the adjacent upper and lower first guide frames 51. Gears 53 are connected to the threaded rods 44, and the gears 53 can mesh with the adjacent racks 52. Four winding rods 55 are horizontally symmetrically distributed and connected to the non - adjacent sides of the upper part of the side plates 3. Two guide rods 57 are horizontally symmetrically distributed and connected to the non - adjacent sides of the top of the side plates 3. Slide plates 56 are slidably connected between the adjacent guide rods 57. Extension plates 58 are rotatably connected to the tops of the side plates 3 and are used to extend the height of the reinforcement. The slide plates 56 can push the adjacent extension plates 58. Two pull ropes 54 are connected between the lower parts of the slide plates 56 and the tops of the adjacent racks 52. The pull ropes 54 are wound around the corresponding winding rods 55 and are guided by the winding rods 55.
[0033] It should be noted that when reinforcing the cast column, when the height of the cast column exceeds the height of the side plate 3, in order to improve the reinforcement effect, the reinforcement height can be extended through the extension plate 58. As the output shaft of the servo motor 42 rotates, the threaded rods 44 will rotate correspondingly at this time, so that the gears 53 will all start to rotate. The rotation of the gears 53 will drive the adjacent racks 52 to slide downward. During the downward sliding of the racks 52, the corresponding two pull ropes 54 will be pulled downward. At this time, the pull ropes 54 will move stably under the guiding action of the corresponding winding rods 55 to avoid the winding of the pull ropes 54. As the pull ropes 54 start to move, the corresponding sliding plates 56 will be pulled upward. In the initial state, the extension plates 58 are all in the non-flipped state. After the sliding plates 56 start to slide upward, the sliding plates 56 will push the adjacent extension plates 58 to flip upward. When the sliding plates 56 can no longer slide, the extension plates 58 complete the flipping and remain on the same horizontal plane as the adjacent side plates 3, thereby increasing the reinforcement height of the side plates 3 for the cast column. When the casting is completed, as the gears 53 start to rotate in the reverse direction, the racks 52 will slide upward and reset, so that the pull ropes 54 are no longer under stress. Under the action of the gravity of the sliding plates 56 themselves, the sliding plates 56 will slide downward and reset. At this time, the extension plates 58 are no longer squeezed and limited by the sliding plates 56. Under the action of the gravity of the extension plates 58 themselves, the extension plates 58 will flip and reset to the side where they are away from each other. To sum up, by driving the threaded rod 44 to rotate through the output shaft of the servo motor 42, the gear 53 drives the rack 52 to slide downward, and then the sliding plate 56 pushes the extension plate 58 to flip upward to extend the reinforcement height of the side plate 3, so that the cast columns of different heights can be reinforced and stabilized.
[0034] As Figure 1 and Figure 5 shown, it further includes a clamping mechanism 6. The clamping mechanism 6 includes a first cross plate 61, a second cross plate 62, a first bidirectional lead screw 63, a cushion block 64 and a nut 65. The non-adjacent sides of the lower parts of the front and rear side plates 3 and the non-adjacent sides of the middle positions of the left and right side plates 3 are all connected with the second cross plate 62 by bolts. The second cross plates 62 are all connected with the first bidirectional lead screw 63. Symmetrical first cross plates 61 are slidably connected between the left and right adjacent first bidirectional lead screws 63 and the front and rear adjacent first bidirectional lead screws 63. The first cross plates 61 are used to clamp and fix the side plates 3. Nuts 65 are threadedly connected to the first bidirectional lead screws 63. Cushion blocks 64 are connected to the first cross plates 61. The cushion blocks 64 can be pushed by the adjacent nuts 65.
[0035] It should be noted that after the side plates 3 are all attached and reinforced to the casting columns, the nuts 65 can be rotated to push the cushion blocks 64 to move towards the side of the side plates 3, so that the first cross plates 61 all slide towards the side of the side plates 3 and clamp and fix the side plates 3, improving the reinforcement effect of the side plates 3 on the casting columns. In summary, by rotating the nuts 65 to push the cushion blocks 64 to slide, the first cross plates 61 all slide towards the side of the side plates 3, thereby reinforcing and stabilizing the side plates 3 and improving the reinforcement effect of the side plates 3 on the casting columns.
[0036] As Figure 1 and Figure 6 shown, it further includes a fixing mechanism 7. The fixing mechanism 7 includes a second bidirectional lead screw 71, second guide frames 72, sliding clamping frames 73 and clamping rods 74. The non-adjacent sides of the expansion plates 58 on the front and rear sides are all rotatably connected with the second bidirectional lead screw 71. The non-adjacent sides of the expansion plates 58 on the front and rear sides are all connected with left and right symmetric second guide frames 72. The second guide frames 72 are all slidably connected with sliding clamping frames 73. The lower parts of the sliding clamping frames 73 are all threadedly connected with the adjacent second bidirectional lead screw 71. The non-adjacent sides of the left and right expansion plates 58 are all connected with front and rear symmetric clamping rods 74. The clamping rods 74 can be clamped with the adjacent sliding clamping frames 73.
[0037] It should be noted that after the expansion plates 58 are all rotated and unfolded, the clamping rods 74 on the left and right sides will be clamped with the sliding clamping frames 73, so that the expansion plates 58 can be kept stable and prevent the expansion plates 58 from accidentally flipping during the reinforcement process. When the reinforcement is completed and the expansion plates 58 need to be flipped and reset, only the second bidirectional lead screw 71 needs to be rotated, so that the sliding clamping frames 73 all slide towards the side close to each other, and then the sliding clamping frames 73 are disengaged from the clamping with the adjacent clamping rods 74. At this time, the expansion plates 58 are all released from the locked state. In summary, by clamping the sliding clamping frames 73 with the adjacent clamping rods 74, the four expansion plates 58 enter the locked state. After the expansion plates 58 enter the locked state, the stability is enhanced, and the expansion plates 58 can be prevented from accidentally flipping during the reinforcement process.
[0038] As Figure 1 and Figure 7 shown, it further includes a limiting mechanism 8. The limiting mechanism 8 includes a rotating rod 81, a torsion spring 82 and an L-shaped clamping member 83. The non-adjacent sides of the upper parts of the side plates 3 are all rotatably connected with the rotating rod 81. A torsion spring 82 is connected between the rotating rod 81 and the adjacent side plate 3. An L-shaped clamping member 83 is connected to the rotating rod 81. The L-shaped clamping member 81 is used to lock and fix the adjacent sliding plates 56.
[0039] It should be noted that in order to prevent the skateboard 56 from accidentally sliding down after pushing and flipping the extension board 58 when the skateboard 56 slides upward, the adjacent skateboard 56 can be clamped by the L-shaped clip 83, so that the skateboard 56 is in a locked state. It should be particularly noted that as the skateboard 56 slides upward, the skateboard 56 will push the L-shaped clamping rod 74 to rotate and expand toward the side away from each other, causing the torsion spring 82 to be deformed by force. As the skateboard 56 moves to the extreme position, at this time the skateboard 56 no longer pushes the adjacent L-shaped clamping rod 74. Under the action of the torsion spring 82, the rotating rod 81 will drive the adjacent L-shaped clamping rod 74 to rotate back to its original position and be clamped with the skateboard 56. To sum up, the adjacent skateboard 56 is clamped by the L-shaped clip 83, so that the skateboard 56 is in a locked state, avoiding the skateboard 56 from accidentally sliding down and resetting, resulting in the extension board 58 losing the limit support.
[0040] As Figure 1 and Figure 8 shown, it further includes a locking mechanism 9. The locking mechanism 9 includes a bolt 91 and a fixing rod 92. The fixing rod 92 is connected to the upper side of the right front part of the chassis assembly 1, and the bolt 91 is slidably connected to the fixing rod 92.
[0041] It should be noted that when the device needs to be disassembled after reinforcement, the bolt 91 is pulled out upward to make the chassis assembly 1 out of the locked state, and then the chassis assembly 1 is rotated and unfolded to complete the disassembly.
[0042] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that these embodiments can be changed without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
