Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a formwork fixing device for building construction. Background Technology

[0002] Formwork is an indispensable tool in modern construction, primarily used for shaping and supporting concrete during pouring. Depending on the material, formwork can be categorized into wooden formwork, steel formwork, aluminum alloy formwork, etc., and is widely used in the construction of walls, floors, columns, and other structures. Among these, the formwork fixing device, as a crucial component ensuring formwork stability and construction safety, directly impacts project quality and construction efficiency. Existing formwork fixing devices typically consist of clamps, support rods, and connectors, mechanically securing the formwork to its designed position to prevent displacement or deformation during concrete pouring.

[0003] Currently available formwork fixing devices have certain limitations in practical applications. Some devices are designed to enhance stability, resulting in lengthy installation and disassembly processes; while some simple fixing devices, although easy to operate, are prone to loosening or shifting under high-intensity construction environments. Furthermore, existing devices lack versatility when adapting to different formwork sizes, often requiring additional adapter components, increasing construction costs and management complexity. Therefore, there is an urgent need for a formwork fixing device for construction engineering that balances ease of operation, stability, and versatility to meet the needs of modern construction. Utility Model Content

[0004] The purpose of this utility model is to provide a formwork fixing device for construction engineering to solve the problems mentioned in the background art: existing formwork fixing devices have the following shortcomings in practical applications: long installation and disassembly time, easy loosening or displacement under high-strength environment, and weak versatility when adapting to different specifications of formwork.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a formwork fixing device for construction engineering, comprising a main support and a secondary support. An adjustment mechanism is provided between the main support and the secondary support, and the main support and the secondary support are connected through the adjustment mechanism. When the driving component on the main support rotates forward, the adjustment mechanism extends, driving the secondary support away from the main support and simultaneously driving the slider on the secondary support to move, so as to achieve the purpose of synchronously unfolding the clamping components on the main support and the secondary support. A driving component is fixedly connected inside the main support, and a threaded rod is provided between the driving component and the main support. One end of the threaded rod is rotatably connected to the main support, and the other end of the threaded rod is fixedly connected to the output end of the driving component. A support plate is fixedly connected inside the secondary support, and a guide rod is fixedly connected between the support plate and the secondary support. A slider is sleeved on the outside of both the guide rod and the threaded rod. One slider is slidably connected to the guide rod, and the other slider is threadedly connected to the threaded rod. A clamping component is provided on the top of the slider. The clamping component can be flipped up and down, which, together with the horizontal adjustment between the main support and the secondary support, reduces the space occupied by the entire fixing device, facilitates its handling, and improves the flexibility and convenience of use.

[0006] Preferably, the adjustment mechanism includes a first connecting rod, which is rotatably connected to the main support. A second connecting rod is rotatably connected to the top of the first connecting rod, and the second connecting rod is rotatably connected to the slider. The first and second connecting rods are of the same specification and are arranged in a cross pattern. There are a total of three sets of the first and second connecting rods, which are rotatably connected end to end. In the set closest to the sub-support, the first connecting rod is rotatably connected to the slider on the guide rod, while the second connecting rod is directly rotatably connected to the sub-support.

[0007] Preferably, both the main bracket and the secondary bracket have mounting holes inside, with two mounting holes on each of the main bracket and the secondary bracket. The mounting holes are used to insert fixing pins, which are then used to finally lock the entire assembly.

[0008] Preferably, the clamping assembly includes a first clamping plate, which is rotatably connected to the slider. A transmission rod is provided between the first clamping plate and the main support. Under the action of the transmission rod, when the threaded rod drives the slider to move, the first clamping plate on the slider will be pushed or pulled by the transmission rod, thereby causing the first clamping plate to automatically flip up or down. One end of the transmission rod is rotatably connected to the main support, and the other end of the transmission rod is rotatably connected to the first clamping plate. A first side plate is rotatably connected to one side of the first clamping plate, and a second side plate is rotatably connected to the other side of the first clamping plate. A second clamping plate is rotatably connected between the first side plate and the second side plate. Racks are fixedly connected to the outside of both the second clamping plate and the first clamping plate. The two sides are interlocked. An auxiliary rod is provided between the first side plate and the slider. One end of the auxiliary rod is rotatably connected to the first side plate, and the other end of the auxiliary rod is rotatably connected to the slider. The four positions of the auxiliary rod (one end rotating with the first side plate), the auxiliary rod (the other end rotating with the slider), the first side plate (the first clamping plate), and the first clamping plate (the slider) form a parallelogram, ensuring that the auxiliary rod and the first clamping plate are always parallel to each other. When the first clamping plate flips, the auxiliary rod pushes and pulls the first side plate. With the cooperation of two meshing racks, the first side plate drives the second clamping plate to flip around the first clamping plate until the second clamping plate and the first clamping plate are in the same straight line or parallel to each other.

[0009] Preferably, both the first and second clamping plates have storage cavities inside. A rotating shaft is rotatably connected inside the storage cavity. A roll is sleeved on the outside of the rotating shaft. Multiple rolls are arranged on the rotating shaft and are evenly distributed. The rolls are fixedly connected to the rotating shaft. A binding strap is wound around the outside of the roll and is fixedly connected to the roll. A torsion spring is sleeved on the outside of the rotating shaft and between the storage cavity and the roll. One end of the torsion spring is fixedly connected to the rotating shaft, and the other end of the torsion spring is fixedly connected to the storage cavity. The torsion spring is mainly used to drive the rotating shaft to rotate automatically, and the rotating shaft then drives the roll to rotate to wind up the binding strap.

[0010] Preferably, a protective cover is detachably connected to the inside of the storage cavity. The protective cover has a through groove inside, which is used in conjunction with the strap. The first clamp and the second clamp are fixed to the protective cover by bolts. The protective cover can seal the storage cavity on the first clamp and the second clamp to prevent debris from entering the storage cavity. The strap extends directly through the through groove on the protective cover to the outside.

[0011] Preferably, both the main support and the secondary support are fixedly connected to guide rails inside, and a guide groove is provided inside the slider on the side near the guide rail. The guide groove works in conjunction with the guide rail to limit the slider's movement, making the slider move more smoothly.

[0012] Preferably, the sub-support has a sliding groove inside, and a roller is rotatably connected inside the sliding groove. There are two sliding grooves, which are symmetrically distributed. When the drive component is started, the drive component will drive the slider to move through the threaded rod. The slider will drive the sub-support to move through the adjustment mechanism, so that the sub-support moves away from or closer to the main support, thereby realizing the automatic unfolding and folding of the whole.

[0013] Preferably, an operating switch is fixedly connected to the outside of the main bracket, the drive component is electrically connected to the operating switch, the electrical equipment is powered by an external power source, such as a battery, and the start, stop, forward and reverse rotation of the drive component are controlled by the operating switch.

[0014] Compared with the prior art, the technical effects of this utility model are:

[0015] 1) When using this formwork fixing device for construction projects, start the drive component to rotate forward, the adjustment mechanism extends and drives the secondary support away from the main support, the straps lengthen, and at the same time the first and second clamps flip upward to a vertical position. At this time, the adjustment mechanism is also fully extended. Finally, pass the fixing pin through the mounting holes on the main support and the secondary support and insert it into the ground to complete the overall installation. After pulling out the fixing pin, control the drive component to rotate in the opposite direction to fold the whole thing up. Whether in the horizontal or vertical direction, the overall volume is greatly reduced, making it more convenient to transport, and the operation is simple and quick.

[0016] 2) When this formwork fixing device is in use, the torsion spring drives the rotating shaft and the drum to rotate. When the fixing device is folded as a whole, the binding straps are automatically wound up. When the fixing device is unfolded as a whole, the binding straps can be automatically stretched. There is no need to pull the binding straps separately, which reduces the operation steps of the fixing device.

[0017] 3) When the formwork fixing device of this building project is in use, the binding strap is wound up by the drum and then stored in the storage cavity of the first clamp and the second clamp. The storage cavity is sealed by the protective cover. The protective cover can prevent debris from entering the storage cavity. The protective cover has a through groove, through which the binding strap can pass directly. Attached Figure Description

[0023] This utility model provides a formwork fixing device for building engineering, the structure and operating principle of which can be described in detail with reference to the accompanying drawings. Figure 1 As shown, the device includes main components such as a main support 1, a secondary support 2, an adjustment mechanism 3, a clamping assembly 8, and a drive assembly 4. These components work together through specific connections and cooperative relationships to achieve the function of fixing the template. An adjustment mechanism 3 is provided between the main support 1 and the secondary support 2 to adjust the distance between them, thereby adapting to the needs of templates of different specifications. The drive assembly 4 is fixedly connected inside the main support 1. The drive assembly 4 is fixedly connected to one end of a threaded rod 5, while the other end of the threaded rod 5 is rotatably connected to the main support 1. A support plate is fixedly connected inside the secondary support 2. A guide rod 6 is fixedly connected to the support plate. Slider 7s are fitted on the outside of both the guide rod 6 and the threaded rod 5. The slider 7 closer to the threaded rod 5 is threadedly connected to it, while the slider 7 closer to the guide rod 6 is slidably connected to it. A clamping assembly 8 is provided on the top of the slider 7 for clamping the template.

[0024] The specific structure of the regulating mechanism 3 is as follows: Figure 2 As shown, it includes a first link 9 and a second link 10. The first link 9 is rotatably connected to the main support 1, and the second link 10 is rotatably connected to the slider 7. The first link 9 and the second link 10 are also rotatably connected to form a cross structure. A total of three sets of the first link 9 and the second link 10 are arranged, connected end-to-end to form an extension and retraction linkage mechanism. In the set closest to the sub-support 2, the first link 9 is rotatably connected to the slider 7 on the guide rod 6, while the second link 10 is directly rotatably connected to the sub-support 2. This multi-link design ensures that the main support 1 and the sub-support 2 maintain synchronization during extension or retraction, and achieves the automatic extension function of the entire device by adjusting the unfolded state of the mechanism 3.

[0025] The structural details of clamping component 8 are as follows Figure 3As shown, it mainly includes components such as a first clamping plate 12, a transmission rod 13, a first side plate 14, a second side plate 15, a second clamping plate 16, and a rack 17. The first clamping plate 12 is rotatably connected to the slider 7. One end of the transmission rod 13 is rotatably connected to the main support 1, and the other end is rotatably connected to the first clamping plate 12. When the slider 7 moves along the guide rod 6, the transmission rod 13 applies a pushing and pulling action to the first clamping plate 12, causing the first clamping plate 12 to rotate around its rotation point. The two sides of the first clamping plate 12 are rotatably connected to the first side plate 14 and the second side plate 15, respectively. An auxiliary rod 18 is provided between the first side plate 14 and the slider 7, and the two ends of the auxiliary rod 18 are rotatably connected to the first side plate 14 and the slider 7, respectively. The four rotation points of the auxiliary rod 18, the first side plate 14, the first clamping plate 12, and the slider 7 form a parallelogram structure. This design ensures that the auxiliary rod 18 always maintains a parallel relationship with the first clamping plate 12, thereby driving the first side plate 14 to move when the first clamping plate 12 rotates. The first side plate 14 and the second clamping plate 16 are connected by a rack 17, which is fixed to the outside of the first clamping plate 12 and the second clamping plate 16 respectively. When the first clamping plate 12 is flipped, the meshing action of the rack 17 causes the second clamping plate 16 to flip accordingly, thus realizing the synchronous unfolding or folding function of the first clamping plate 12 and the second clamping plate 16.

[0026] To facilitate the storage and use of the straps 22, both the first clamping plate 12 and the second clamping plate 16 have storage cavities 19. A rotating shaft 20 is rotatably connected within each storage cavity 19. Multiple rollers 21 are fitted around the rotating shaft 20, with the straps 22 wound around each roller. A torsion spring 23 is also fitted around the rotating shaft 20, with one end fixedly connected to the rotating shaft 20 and the other end fixedly connected to the storage cavity 19. When the fastening device is folded, the torsion spring 23 drives the rotating shaft 20 to rotate automatically, thereby winding the straps 22 into the storage cavity 19 via the rollers 21. When the fastening device is unfolded, the straps 22 are stretched and extend out of the storage cavity 19, allowing for the placement of the straps 22 without manual intervention. To protect the components inside the storage cavity 19, a protective cover 24 is bolted to the outside of the first clamping plate 12 and the second clamping plate 16. A through groove is opened inside the protective cover 24, through which the strap 22 can extend to the outside, while preventing debris from entering the storage cavity 19.

[0027] Both the main support 1 and the auxiliary support 2 are fixedly connected to guide rails 25 inside. A guide groove is provided inside the slider 7 on the side near the guide rail 25, and the guide groove cooperates with the guide rail 25 to ensure that the slider 7 remains stable during movement. The auxiliary support 2 has two symmetrically distributed sliding grooves inside, and rollers 26 are rotatably connected within the sliding grooves. The design of the rollers 26 reduces the frictional resistance of the auxiliary support 2 during movement. An operating switch 27 is fixedly connected to the outside of the main support 1. The operating switch 27 is electrically connected to the drive assembly 4, and controls the start, stop, and forward / reverse rotation of the drive assembly 4 through the operating switch 27, thereby realizing the automated operation of the entire device.

[0028] The working process of this device is as follows: First, the drive assembly 4 is started to rotate forward by operating switch 27. The drive assembly 4 drives the threaded rod 5 to rotate, and the rotation of the threaded rod 5 pushes the slider 7 to move outward along the guide rod 6. The movement of the slider 7 drives the sub-support 2 away from the main support 1 through the first connecting rod 9 and the second connecting rod 10 of the adjusting mechanism 3. At the same time, the movement of the slider 7 also pushes the first clamping plate 12 to flip to a vertical position through the transmission rod 13. During this process, the binding strap 22 is stretched and extends from the storage cavity 19 until the first clamping plate 12 and the second clamping plate 16 are fully unfolded and in contact with the template. At this time, the fixing pin is inserted into the mounting holes 11 on the main support 1 and the sub-support 2 to lock the device position and complete the template fixing operation. When disassembly is required, pull out the fixing pin and control the drive assembly 4 to rotate in the opposite direction by operating switch 27. The threaded rod 5 drives the slider 7 to move inward, the adjusting mechanism 3 retracts, the secondary bracket 2 moves closer to the main bracket 1, the first clamping plate 12 and the second clamping plate 16 flip back to the horizontal state, and the strap 22 is automatically rolled into the storage cavity 19 by the torsion spring 23, thus realizing the folding and storage of the entire device.

[0029] The above description details the specific connection relationships, positional relationships, and mutual cooperation relationships of the various components of this utility model, ensuring that those skilled in the art can successfully implement this technical solution based on the contents of the specification.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0031] When fixing wall formwork at a construction site, the main support 1 and the secondary support 2 are first placed on both sides of the formwork, and the drive assembly 4 is started to rotate forward by operating switch 27. The drive assembly 4 drives the threaded rod 5 to rotate, and the threaded connection between the threaded rod 5 and the slider 7 causes the slider 7 to move outward along the guide rod 6. During this process, the movement of the slider 7 is linked by the first connecting rod 9 and the second connecting rod 10 of the adjusting mechanism 3, pushing the secondary support 2 away from the main support 1, thereby expanding the distance between the main support 1 and the secondary support 2. This expansion process can adapt to the needs of different specifications of formwork, ensuring that the device has high versatility.

[0032] Simultaneously, the movement of slider 7 also applies a pushing force to the first clamping plate 12 via transmission rod 13, causing the first clamping plate 12 to flip upwards around its rotation point with slider 7 to a vertical position. The flipping of the first clamping plate 12 drives the first side plate 14 to move via auxiliary rod 18 and parallelogram structure, which in turn causes the second clamping plate 16 to flip synchronously through the meshing action of rack 17. When the first clamping plate 12 and the second clamping plate 16 are fully extended and in contact with the template, the binding strap 22 is pulled out from the storage cavity 19 and automatically extends to the outside. At this time, the fixing pin is inserted into the mounting holes 11 on the main support 1 and the auxiliary support 2 to complete the template fixing operation. This step achieves rapid template clamping through mechanical linkage, avoiding the time-consuming operation problem caused by manual adjustment in traditional devices.

[0033] When the formwork needs to be dismantled after construction, the fixing pin is pulled out, and the drive assembly 4 is rotated in reverse by operating switch 27. The threaded rod 5 drives the slider 7 to move inward along the guide rod 6. The movement of the slider 7 is linked by the first link 9 and the second link 10 of the adjusting mechanism 3, pulling the sub-support 2 closer to the main support 1. At the same time, the transmission rod 13 pulls the first clamping plate 12 downward and flips it back to a horizontal state. During this process, the binding strap 22 is automatically wound into the storage cavity 19 by the rotating shaft 20 driven by the torsion spring 23, and the binding strap 22 can be stored without manual intervention. Finally, the entire device folds into a compact form, which is convenient for transportation and storage.

[0034] During the aforementioned operation, the design of the guide rail 25 and the guide groove ensures the stability of the slider 7 during movement, while the roller 26 effectively reduces the frictional resistance of the sub-support 2 during movement, further improving the smoothness of the device's operation. Furthermore, the protective cover 24 is bolted to the outside of the first clamping plate 12 and the second clamping plate 16, protecting not only the components inside the storage cavity 19 but also allowing the strap 22 to extend smoothly to the outside through the through-slot design, preventing debris from entering the storage cavity 19, thereby ensuring the long-term stability and reliability of the device.

[0035] In summary, this utility model, through the automatic retraction and extension design of the drive component 4, adjustment mechanism 3, clamping component 8, and binding strap 22, achieves rapid installation and disassembly of the template fixing device, significantly improving construction efficiency. Simultaneously, the device's folding function reduces its space requirements during handling and storage, fully meeting the multiple demands of modern construction for convenience, stability, and versatility. The above description details the specific operating steps and principles of this utility model in practical applications, ensuring that those skilled in the art can successfully implement this technical solution based on the description.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
