Description

Technical Field

[0001] This invention relates to the field of auxiliary devices for building construction, and in particular to a concrete formwork reinforcement device. Background Technology

[0002] Doors and windows are important components of architectural design. In the secondary structural construction of building projects, reinforcing the formwork of the secondary structural frame columns at door and window openings is a challenging task, often resulting in quality problems. Traditional formwork systems for door and window openings mainly rely on prefabricated timber structures. The formwork is fixed to the timber with nails, and the timber is supported by short timber beams, which are also secured with nails.

[0003] In the related technology, Chinese utility model patent with publication number CN216516894U discloses a formwork support component for door and window openings in building engineering, including a horizontal support rod, a first vertical support rod at the bottom end of the horizontal support rod, a first vertical support rod between the same ends of the two horizontal support rods, a second vertical support rod on one side of the first vertical support rod, and opposite-direction screws movably installed on one side of both the first and second vertical support rods. One end of the opposite-direction screw is threaded to a first clamping plate, and the side of the opposite-direction screw away from the first clamping plate is threaded to a second clamping plate.

[0004] Regarding the aforementioned technologies, when the size of the door and window openings exceeds the adjustment range of the template support, the template support cannot clamp and fix the templates on both sides of the door and window openings. Therefore, it is necessary to manufacture template support of different sizes for door and window openings of different sizes, which is not convenient for the reuse of template reinforcement devices and increases manufacturing costs. Summary of the Invention

[0005] To facilitate the reuse of formwork reinforcement devices, this application provides a concrete formwork reinforcement device.

[0006] The concrete formwork reinforcement device provided in this application adopts the following technical solution:

[0007] A concrete formwork reinforcement device includes a horizontal bar, a first clamping member and a second clamping member slidably disposed on the horizontal bar, and a fastening mechanism for driving the second clamping member to approach the first clamping member, wherein the formwork on both sides of the door and window openings is located between the first clamping member and the second clamping member.

[0008] By adopting the above technical solution, the templates on both sides of the door and window openings are located between the first clamping member and the second clamping member. Multiple template reinforcement devices are evenly distributed at the door and window openings. When the fastening mechanism drives the second clamping member to approach the first clamping member, the first clamping member and the second clamping member can clamp and fix the templates on both sides of the door and window openings, thereby increasing the stability of the templates at the door and window openings. At the same time, each template reinforcement device can be used independently, and the number of template reinforcement devices can be increased according to the size of different door and window openings. Furthermore, it is more convenient to reuse them after use, thus reducing manufacturing costs.

[0009] Preferably, an end plate is fixedly connected to one end face of the transverse rod, the end plate being located at the end of the first clamping member away from the second clamping member. The fastening mechanism includes a connecting rod mounted on the end plate, the length direction of the connecting rod being parallel to the length direction of the transverse rod. A first ear plate is fixedly connected to the first clamping member, and a second ear plate is fixedly connected to the second clamping member. The connecting rod passes through the first ear plate and the second ear plate, and both the first ear plate and the second ear plate are slidably disposed on the connecting rod. A nut is threadedly connected to the connecting rod, and the nut is located on the side of the second ear plate away from the first ear plate.

[0010] By adopting the above technical solution, when the nut rotates, the nut can move closer to the end plate. After the nut abuts against the second ear plate, as the nut continues to rotate, the nut can drive the second clamping member to move closer to the first clamping member through the second ear plate, so that the first clamping member and the second clamping member clamp and fix the template on both sides of the door and window opening, which facilitates the disassembly and installation of the template reinforcement device.

[0011] Preferably, the fastening mechanism includes a drive assembly, which includes a driven gear sleeved on the nut. A mounting plate is fixedly connected to the side of the second ear plate away from the first ear plate. A motor is fixedly connected to the mounting plate, and a drive gear that can mesh with the driven gear is fixedly connected to the output shaft of the motor.

[0012] By adopting the above technical solution, the drive gear meshes with the driven gear. When the motor starts in the forward direction, the drive gear drives the driven gear to rotate, thereby causing the driven gear to rotate the nut and move towards the first ear plate. At this time, the second ear plate moves towards the first ear plate under the push of the nut, thereby clamping the first clamping member and the second clamping member towards the templates on both sides of the door and window opening, making it convenient for workers to adjust the nut.

[0013] Preferably, the first clamping member includes a first sliding tube and a first clamping rod fixed to the first sliding tube, the first sliding tube being sleeved on the transverse rod and slidably disposed on the transverse rod; the second clamping member includes a second sliding tube and a second clamping rod fixed to the second sliding tube, the second sliding tube being sleeved on the transverse rod and slidably disposed on the transverse rod.

[0014] By adopting the above technical solution, both the first sliding tube and the second sliding tube are slidably mounted on the horizontal bar, making the structure of the template reinforcement device more stable.

[0015] Preferably, a sliding groove is provided on the side of the second clamping rod near the first clamping rod, and a communicating hole is provided on the inner wall of the sliding groove away from the first clamping rod. A control component is provided in the sliding groove. The control component includes a control block slidably disposed in the sliding groove, a control rod fixedly connected to the control block, and the control rod slidably disposed in the communicating hole. A first fixed contact is embedded in the inner wall of the sliding groove, and a movable contact that can contact the first fixed contact is embedded in the control block. A power supply is fixedly installed on the second clamping rod. The first fixed contact is electrically connected to one terminal of the motor, the other terminal of the motor is electrically connected to one electrode of the power supply, and the other terminal of the power supply is electrically connected to the movable contact.

[0016] By adopting the above technical solution, the first fixed contact is electrically connected to one of the terminals of the motor, the other terminal of the motor is electrically connected to one of the electrodes of the power supply, and the other terminal of the power supply is electrically connected to the moving contact. The construction personnel can control the on / off of the forward rotation circuit of the motor by sliding the control rod. When the control rod is pushed towards the first clamping rod, the moving contact comes into contact with the first fixed contact. At this time, the end of the control block away from the control rod protrudes into the sliding groove. As the second clamping rod moves closer to the first clamping rod, after the first and second clamping rods clamp the templates on both sides of the door and window opening, the control block can slide into the sliding groove under the action of the contact with the template, so that the moving contact is separated from the first fixed contact. Thus, after the first and second clamping rods clamp the templates on both sides of the door and window opening, the motor circuit is automatically disconnected and the nut automatically stops rotating.

[0017] Preferably, a second fixed contact is embedded in the inner wall of the sliding groove, which can contact the moving contact. The second fixed contact is located on the side of the first fixed contact away from the first clamping rod. A second power supply and a commutation module are also fixedly installed on the second clamping rod. The second fixed contact is electrically connected to one of the terminals of the motor. The other terminal of the motor is electrically connected to one of the terminals of the commutation module. The other terminal of the commutation module is electrically connected to one of the electrodes of the second power supply. The other electrode of the second power supply is electrically connected to the moving contact.

[0018] By adopting the above technical solution, the second fixed contact is electrically connected to one of the terminals of the motor, the other terminal of the motor is electrically connected to one of the terminals of the commutation module, the other terminal of the commutation module is electrically connected to one of the electrodes of the power supply, and the other electrode of the power supply is electrically connected to the moving contact. When the control lever is pulled away from the first clamping lever, the moving contact can contact the second fixed contact, thereby enabling the motor to rotate in the opposite direction and drive the nut to rotate in the opposite direction. At this time, since the control lever is pulled away from the first clamping lever, the second clamping lever can drive the second ear plate to always be in contact with the nut, thereby keeping the drive gear and the driven gear in contact, so that when the motor reverses, it can stably drive the nut to move away from the first ear plate.

[0019] Preferably, a spring is provided in the sliding groove, one end of the spring is fixed to the side of the control block away from the first clamping rod, and the other end of the spring is fixedly connected to the inner wall of the sliding groove away from the first clamping rod.

[0020] By adopting the above technical solution, one end of the spring is fixed to the side of the control block away from the first clamping rod, and the other end of the spring is fixedly connected to the inner wall of the sliding groove away from the first clamping rod, so that the moving contact can be held between the first fixed contact and the second fixed contact without external force.

[0021] Preferably, a pull block is fixedly connected to the control rod, and the pull block is located on the outer peripheral surface of the control rod.

[0022] By adopting the above technical solution, the pull block is fixedly connected to the outer circumference of the control rod, thereby facilitating the pushing and pulling of the control rod.

[0023] Preferably, a limiting groove is formed on the inner wall of the sliding groove, and a limiting block is fixedly connected to the side of the control block, with the limiting block sliding within the limiting groove.

[0024] By adopting the above technical solution, the limiting block is slidably set in the limiting groove, thereby preventing the control block from leaving the limiting groove, making the structure of the control component more stable.

[0025] Preferably, a slot is provided on the top surface of the end plate, and a vertical hole is provided on the side of the slot near the second clamping member. One end of the connecting rod is fixedly connected to a plug, the plug is inserted into the slot, and the connecting rod is inserted into the vertical hole.

[0026] By adopting the above technical solution, the insert block is inserted into the slot and the connecting rod is inserted into the vertical hole, which facilitates the assembly and disassembly of the template reinforcement device.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The templates on both sides of the door and window openings are located between the first clamping member and the second clamping member. Multiple template reinforcement devices are evenly distributed at the door and window openings. When the fastening mechanism drives the second clamping member to approach the first clamping member, the first clamping member and the second clamping member can clamp and fix the templates on both sides of the door and window openings, thereby increasing the stability of the templates at the door and window openings. At the same time, each template reinforcement device can be used independently, and the number of template reinforcement devices can be increased according to the size of different door and window openings. Furthermore, it is more convenient to reuse them after use, thus reducing manufacturing costs.

[0029] 2. The first fixed contact is electrically connected to one of the terminals of the motor, and the other terminal of the motor is electrically connected to one of the electrodes of the power supply. The other terminal of the power supply is electrically connected to the moving contact. The construction personnel can control the on / off of the motor's forward rotation circuit by sliding the control rod. When the control rod is pushed towards the first clamping rod, the moving contact contacts the first fixed contact. At this time, the end of the control block away from the control rod protrudes into the sliding groove. As the second clamping rod moves closer to the first clamping rod, after the first and second clamping rods clamp the templates on both sides of the door and window opening, the control block can slide into the sliding groove under the action of the template, causing the moving contact to disengage from the first fixed contact. Thus, after the first and second clamping rods clamp the templates on both sides of the door and window opening, the motor's circuit is automatically disconnected, and the nut automatically stops rotating.

[0030] 3. The second fixed contact is electrically connected to one of the terminals of the motor, the other terminal of the motor is electrically connected to one of the terminals of the commutation module, the other terminal of the commutation module is electrically connected to one of the electrodes of the power supply, and the other electrode of the power supply is electrically connected to the moving contact. When the control lever is pulled away from the first clamping lever, the moving contact can contact the second fixed contact, thereby enabling the motor to rotate in the reverse direction and drive the nut to rotate in the reverse direction. At this time, since the control lever is pulled away from the first clamping lever, the second clamping lever can drive the second ear plate to always be in contact with the nut, thereby keeping the drive gear and the driven gear in contact, so that when the motor reverses, it can stably drive the nut to move away from the first ear plate.

[0047] Reference Figure 1 and Figure 4 As shown, the end of the control lever 452 away from the first clamping lever 22 extends to the outside of the second clamping lever 32, and a pull block 4521 is fixedly connected to the control lever 452, with the pull block 4521 located on the outer peripheral surface of the control lever 452.

[0048] Reference Figure 1 and Figure 4 As shown, a spring 453 is provided in the sliding groove 321. One end of the spring 453 is fixed to the side of the control block 451 away from the first clamping rod 22, and the other end of the spring 453 is fixedly connected to the inner wall of the sliding groove 321 away from the first clamping rod 22. The spring 453 is sleeved on the outside of the control rod 452.

[0049] Reference Figure 2 and Figure 4 As shown, the first fixed contact 454 is embedded in the inner wall of the sliding groove 321, the movable contact 456 is embedded in the control block 451, and the power supply 457 is fixedly installed on the side of the second clamping rod 32 away from the first clamping rod 22. The first fixed contact 454 is electrically connected to one terminal of the motor 442, the other terminal of the motor 442 is electrically connected to one electrode of the power supply 457, and the other terminal of the power supply 457 is electrically connected to the movable contact 456. When the control rod 452 is pushed towards the first clamping rod 22, the movable contact 456 can contact the first fixed contact 454.

[0050] Reference Figure 2 and Figure 4As shown, the second fixed contact 455 is also embedded in the inner wall of the sliding groove 321. The second fixed contact 455 is located on the side of the first fixed contact 454 away from the first clamping rod 22. The commutation module 459 and the second power supply 458 are both fixedly connected to the side of the second clamping rod 32 away from the first clamping rod 22.

When the control lever 452 is pulled towards the second clamping rod 32, the moving contact 456 can contact the second fixed contact 455.

[0051] Reference Figure 1 As shown, both the first clamping rod 22 and the second clamping rod 32 have through holes 5. When pouring concrete at the door and window openings, the two ends of the tie bolts pass through the through holes 5 on the first clamping rod 22 and the second clamping rod 32 respectively to reinforce the templates on both sides of the door and window openings.

[0052] The implementation principle of the concrete formwork reinforcement device in this application embodiment is as follows: the formwork on both sides of the door and window opening is located between the first clamping member 2 and the second clamping member 3. Multiple formwork reinforcement devices are evenly distributed at the door and window opening. When the fastening mechanism 4 drives the second clamping member 3 to approach the first clamping member 2, the first clamping member 2 and the second clamping member 3 can clamp and fix the formwork on both sides of the door and window opening, thereby increasing the stability of the formwork at the door and window opening. At the same time, each formwork reinforcement device can be used independently, and the number of formwork reinforcement devices can be increased according to the size of different door and window openings. Furthermore, it is more convenient to reuse them after use, thus reducing manufacturing costs.

[0053] When the control lever 452 is pushed toward the first clamping lever 22, the movable contact 456 contacts the first fixed contact 454. At this time, the end of the control block 451 away from the control lever 452 protrudes into the sliding groove 321. As the second clamping lever 32 moves closer to the first clamping lever 22, after the first clamping lever 22 and the second clamping lever 32 clamp the templates on both sides of the door and window opening, the control block 451 can slide into the sliding groove 321 under the action of the contact with the template, so that the movable contact 456 disengages from the first fixed contact 454. After the first clamping lever 22 and the second clamping lever 32 clamp the templates on both sides of the door and window opening, the segment circuit of the motor 442 is automatically disconnected, and the nut 43 automatically stops rotating, so that the first clamping lever 22 and the second clamping lever 32 remain in the clamped state.

[0054] When the control lever 452 is pulled away from the first clamping lever 22, the moving contact 456 can come into contact with the second fixed contact 455, thereby enabling the motor 442 to rotate in the opposite direction and drive the nut 43 to rotate in the opposite direction. At this time, since the control lever 452 is pulled away from the first clamping lever 22, the second clamping lever 32 can drive the second ear plate 311 to always be in contact with the nut 43, thereby keeping the drive gear 443 and the driven gear 444 in contact, so that when the motor 442 reverses, it can stably drive the nut 43 to move away from the first ear plate 211.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
