[0002] Concrete formwork support is an indispensable part of construction projects, which is directly related to construction efficiency, cost and safety. It usually consists of a support composed of vertical poles, horizontal poles, diagonal rods, and connecting plates on the vertical poles, as well as a formwork fixed on the support. It is simple in structure, easy to disassemble, high in safety, has a large load-bearing capacity, and is suitable for various complex environments. It is widely used in housing projects, bridge projects, tunnel projects and other scenes.
[0003] At present, most of the concrete formwork supports are erected using full-floor supports.

When the concrete poured on the formwork solidifies, the construction workers adjust the height between the support frame and the ground again by connecting the lifting part, so that the formwork is separated from the solidified concrete. Finally, a hydraulic trolley or forklift is used to move the support frame together with the formwork and support beam until it is moved to the construction position. In this process, there is no need for construction workers to repeatedly dismantle the support frame, thereby improving the efficiency of concrete construction and helping to reduce construction costs.

[0015] Optionally, an adjusting handle is rotatably connected to the adjusting nut.

In this process, the construction workers do not need to repeatedly dismantle the support frame, thereby improving the efficiency of concrete construction and helping to reduce construction costs; 2. The construction personnel insert the adjustment rod into the bottom of the vertical pole, and then rotate the adjustment nut in the forward direction.

The construction personnel first install the jacking screw on the vertical pole and use the jacking block to achieve preliminary fixation. Then, according to the designed inclination angle of concrete pouring, the installation plate is rotated so that the installation plate drives the support beam and the template on the support beam to be at the designed inclination angle. Then, the locking block is tightened, and the locking block presses the locking teeth on the angle gear ring to fix the inclination angle of the installation plate. Finally, the position of the template is adjusted by twisting the jacking block, so that concrete floors with different angles can be poured. 4. When the lever drives the protrusion to press the tooth plate onto the rack, the compression spring presses the tooth plate onto the protrusion, and the lever, protrusion, tooth plate and rack form a mechanical self-locking effect. At the same time, the gravity of the lever itself prevents the protrusion from rotating accidentally, which is beneficial to reduce the possibility of the tooth plate accidentally falling off the rack, and is beneficial to improving the safety of the support frame for concrete pouring.

[0043] When it is necessary to move the position of the support frame 3 as a whole, the construction personnel first remove the adjusting rod 510 at the bottom of the support frame 3 and the inclined rod 33 on the connecting plate 34 on the bottom rod tube 5191, and then loosen the adjusting nut 518 through the adjusting handle 6 to make the adjusting nut 518 away from the locking pin 517, and at the same time use a hydraulic trolley or forklift to fix the support frame 3, then pull out the locking pin 517, and then slide the adjusting rod 510 to the appropriate position and insert the locking pin 517 again, so that all the adjusting rods 510 at the bottom of the support frame 3 are at the same height.
[0044] The support frame 3 is then lowered by a hydraulic trolley or forklift to separate the formwork 1 from the solidified concrete, and then the support frame 3 is moved to the construction position by a hydraulic trolley or forklift. After the support frame 3 is lifted as a whole to a suitable position by the hydraulic trolley or forklift, the locking pin 517 is pulled out, the adjusting rod 510 is moved to a suitable position, and the locking pin 517 is inserted again.
[0045] And make all the adjustment rods 510 at the bottom of the support frame 3 at the same height again, then turn the fine-tuning screw 5192 to make the bottom plate 5194 on the fine-tuning screw 5192 touch the ground, then tighten the anti-loosening nut 5193 and withdraw the hydraulic trolley or forklift, and finally reinstall the diagonal rod 33. The construction personnel then turn the adjusting screw 401 according to the design requirements, so that the adjusting screw 401 drives the supporting plate 403 to move, thereby moving the template 1 to the designed position for concrete pouring.
[0046] The implementation principle of Example 1 is as follows: the construction personnel build the support frame 3 at the construction location, and fix the template 1 and the support beam 2 on the support frame 3, and then rotate the locking block 402 in the forward direction, and the locking block 402 presses against the reaction force at the end of the vertical pole 31, so that the adjusting screw 401 moves along the axial direction of the vertical pole 31, so that the supporting plate 403 pushes the main beam 21 and the secondary beam 22 to move synchronously, so that the template 1 is in the designed position for concrete pouring.
[0047] When it is necessary to move the position of the support frame 3 as a whole, the construction personnel first remove the adjusting rod 510 at the bottom of the support frame 3 and the inclined rod 33 on the connecting plate 34 on the bottom rod tube 5191, and then loosen the adjusting nut 518 through the adjusting handle 6 to make the adjusting nut 518 away from the locking pin 517, and at the same time use a hydraulic trolley or forklift to fix the support frame 3, then pull out the locking pin 517, and then slide the adjusting rod 510 to the appropriate position and insert the locking pin 517 again, so that all the adjusting rods 510 at the bottom of the support frame 3 are at the same height.
[0048] The support frame 3 is then lowered by a hydraulic trolley or forklift to separate the formwork 1 from the solidified concrete, and then the support frame 3 is moved to the construction position by a hydraulic trolley or forklift. After the support frame 3 is lifted as a whole to a suitable position by the hydraulic trolley or forklift, the locking pin 517 is pulled out, the adjusting rod 510 is moved to a suitable position, and the locking pin 517 is inserted again.
[0049] And make all the adjustment rods 510 at the bottom of the support frame 3 at the same height again, then turn the fine-tuning screw 5192 to make the bottom plate 5194 on the fine-tuning screw 5192 touch the ground, then tighten the anti-loosening nut 5193 and withdraw the hydraulic trolley or forklift, and finally reinstall the inclined rod 33. The construction personnel then turn the adjusting screw 401 according to the design requirements to make the adjusting screw 401 drive the supporting plate 403 to move, so that the template 1 moves to the designed position for concrete pouring Example 2 refer to Figure 4 The difference between this embodiment and embodiment 1 is that the connecting support part 4 includes a mounting plate 404 bolted to the main beam 21, a group of ear plates 405 are welded to the mounting plate 404, an angle shaft 406 is rotatably mounted between the two ear plates 405, a lifting screw 407 is rotatably connected to the angle shaft 406, and the lifting screw 407 is coaxially slidably matched with the vertical rod 31.
[0050] refer to Figure 4The lifting screw 407 is threadedly connected with a lifting block 408, and the lifting block 408 is used to press against the end of the vertical pole 31. An angle gear ring 409 is welded on the ear plate 405, and the angle gear ring 409 is coaxially sleeved on the angle shaft 406. A locking ring 10 is slidingly sleeved on the lifting screw 407, and a locking tooth 410 is welded on the locking ring 10. The locking tooth 410 is used to be clamped on the angle gear ring 409. A locking block 411 is threadedly connected to the lifting screw 407, and the locking block 411 is used to press the locking tooth 410 onto the angle gear ring 409.
[0051] The construction workers first install the lifting screw 407 on the vertical pole 31, and then achieve preliminary fixation by tightening the lifting block 408. Thereafter, according to the designed inclination angle of the concrete pouring, the mounting plate 404 is rotated, so that the mounting plate 404 drives the support beam 2 and the formwork 1 on the support beam 2 to be at the same designed inclination angle, and then the locking block 411 is tightened.
[0052] The locking block 411 pushes the locking ring 10 close to the angle tooth ring 409, so that the locking ring 10 continuously presses the locking tooth 410 onto the angle tooth ring 409, thereby fixing the inclination angle of the mounting plate 404, and then fixing the inclination angle of the formwork 1. Finally, the position of the formwork 1 is fine-tuned by twisting the lifting block 408, so that concrete floors of different angles can be cast.
[0053] Reference Figure 5 and Figure 6 The connecting lifting part 5 includes an outer tube 520, on which a connecting plate 34 is welded, and a support rod 521 is coaxially slidably inserted on the outer tube 520. The support rod 521 is provided with a plurality of pin slots 522 along its axial direction, and a fine-tuning slot 523 is provided between the inner and outer side walls of the outer tube 520 and along its axial direction, and a fixing pin 524 is inserted into the pin slot 522, and the fixing pin 524 passes through the fine-tuning slot 523.
[0054] Reference Figure 5 and Figure 6 A rack 525 is welded on the outer tube 520 along its axial direction, and a briquette tube 526 is slidably sleeved on the outer tube 520. The briquette tube 526 is used to clamp the fixing pin 524. A tooth plate 527 is rotatably connected to the briquette tube 526. An escape groove 528 for the tooth plate 527 to rotate is provided on the briquette tube 526. The tooth plate 527 is used to clamp the rack 525. A compression spring 529 is supported between the side of the tooth plate 527 facing the rack 525 and the escape groove 528 on the briquette tube 526.
[0055] Reference Figure 5 and Figure 6A lever 530 is rotatably connected to the pressing block cylinder 526, a counterweight ball 8 is welded to the lever 530, a protrusion 531 is integrally formed on the lever 530 and at the rotation center of the lever 530, and a circular arc surface 7 is opened on the protrusion 531. When the lever 530 is vertically downward, the circular arc surface 7 on the protrusion 531 presses the tooth plate 527 onto the rack 525. At this time, the rotation center of the lever 530, the center of the circular arc surface 7 on the protrusion 531, and the abutment position of the circular arc surface 7 of the protrusion 531 and the tooth plate 527 are all on the same straight line.
[0056] When it is necessary to adjust the height of the support frame 3 and the ground, the construction worker rotates the lever 530 in the forward direction, and the lever 530 drives the protrusion 531 away from the tooth plate 527. At this time, there is a distance between the protrusion 531 and the tooth plate 527, so the compression spring 529 restores its deformation and pushes the tooth plate 527 away from the rack 525. Then the construction worker slides the pressure block cylinder 526, and then the construction worker pulls out the fixing pin 524 and adjusts the position of the support rod 521 and then inserts the fixing pin 524 again, and finally rotates the lever 530 in the reverse direction.
[0057] Under the action of gravity of the counterweight ball 8, the lever 530 presses the tooth plate 527 against the rack 525 through the protrusion 531, and the compression spring 529 is compressed again. At the same time, the compression spring 529 presses the tooth plate 527 against the protrusion 531. At this time, the rotation center of the lever 530, the center of the arc surface 7 on the protrusion 531, and the contact position between the arc surface 7 of the protrusion 531 and the tooth plate 527 are on the same straight line, the lever 530, the protrusion 531, the tooth plate 527 and the rack 525 form a mechanical self-locking effect. When the pressure block tube 526 is pressed against the fixing pin 524 again, the support rod 521 and the outer tube 520 cannot slide relative to each other.
[0058] The implementation principle of Example 2 is as follows: the locking block 411 pushes the locking ring 10 close to the angle tooth ring 409, so that the locking ring 10 continuously presses the locking tooth 410 onto the angle tooth ring 409, thereby fixing the inclination angle of the mounting plate 404, and then fixing the inclination angle of the formwork 1, and finally fine-tuning the position of the formwork 1 by twisting the jacking block 408, so that concrete floors of different angles can be cast.
[0059] When it is necessary to adjust the height of the support frame 3 and the ground, the construction worker rotates the lever 530 in the forward direction, and the lever 530 drives the protrusion 531 away from the tooth plate 527. At this time, there is a distance between the protrusion 531 and the tooth plate 527, so the compression spring 529 restores its deformation and pushes the tooth plate 527 away from the rack 525. Then the construction worker slides the pressure block cylinder 526, and then the construction worker pulls out the fixing pin 524 and adjusts the position of the support rod 521 and then inserts the fixing pin 524 again, and finally rotates the lever 530 in the reverse direction.
[0060] Under the action of gravity of the counterweight ball 8, the lever 530 presses the tooth plate 527 against the rack 525 through the protrusion 531, and the compression spring 529 is compressed again. At the same time, the compression spring 529 presses the tooth plate 527 against the protrusion 531. At this time, the rotation center of the lever 530, the center of the arc surface 7 on the protrusion 531, and the contact position between the arc surface 7 of the protrusion 531 and the tooth plate 527 are on the same straight line, the lever 530, the protrusion 531, the tooth plate 527 and the rack 525 form a mechanical self-locking effect. When the pressure block tube 526 is pressed against the fixing pin 524 again, the support rod 521 and the outer tube 520 cannot slide relative to each other.
[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
