Description

Technical Field

[0001] This invention relates to the field of floor slab support technology, and more specifically, to a modular formwork support frame for post-cast strips and its construction method. Background Technology

[0002] Post-cast strips are temporary construction joints left in the foundation, walls, and beams during building construction to address cracking caused by structural shrinkage and uneven settlement. By segmenting the structure, concrete is poured after the components have undergone shrinkage and deformation to connect the segments, thereby enhancing structural stability and reducing cracking. To facilitate subsequent support of the floor slabs, a modular formwork support system for post-cast strips is required. This modular formwork support system is specifically designed for post-cast strip construction. Independent of the full-span scaffolding, it possesses sufficient load-bearing capacity, rigidity, and stability, reliably bearing construction loads without affecting assembly or disassembly, ensuring the safety and quality of post-cast strip construction.

[0003] Currently available modular formwork supports for post-cast strips consist of a main support frame and a detachable auxiliary frame. During use, movable inspection panels on the opening and closing sides facilitate maintenance. To improve the overall stability of the formwork support, triangular reinforcing ribs are added to each node of the main support frame for structural reinforcement. Additionally, to enhance the load-bearing capacity of the formwork support, thickened load-bearing pads are installed at the bottom of the auxiliary frame. However, this method makes it difficult to adjust the angle of the floor slab, resulting in an inability to adapt to different support angles. This can affect the installation accuracy of the formwork in complex construction environments, thereby reducing the reliability of the device. Summary of the Invention

[0004] The purpose of this invention is to provide a modular formwork support for post-pouring strips and its construction method, so as to solve the problem mentioned in the background art that the modular formwork support for post-pouring strips is difficult to adjust the angle of the floor slab, resulting in difficulty in adapting to different support angles.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A modular formwork support frame for post-pouring strips includes a mounting plate, an angle adjustment mechanism on the outer side of the mounting plate for adjusting the support angle, a support mechanism on the top of the mounting plate for adjusting the support area, and an installation mechanism on the bottom of the mounting plate for supporting and adjusting devices.

[0007] The angle adjustment mechanism includes a U-shaped frame, which is rotatably connected to the upper side of the mounting plate. A first gear is rotatably connected to the middle of the inner side of the U-shaped frame. Racks are slidably connected to the left and right sides of the inner side of the U-shaped frame. The racks are slidably connected to the first gear. A U-shaped block is fixedly connected to the top of the rack. A telescopic plate is rotatably connected to the inner side of the U-shaped block. A floor slab is fixedly connected to the top of the telescopic plate. A positioning component is provided on the inner side of the U-shaped frame. A handling component is provided on the outer side of the mounting plate.

[0008] Furthermore, the support mechanism includes a first dual-head motor and a belt. The first dual-head motor is fixedly connected to the inner side of the floor slab. Threaded rods are fixedly connected to the front and rear sides of the first dual-head motor. The outer side of the threaded rods penetrates the floor slab and is threadedly connected to a hollow plate. Movable plates are provided on the left and right sides inside the hollow plate. Grooved discs are rotatably connected to the front and rear sides inside the movable plate. The grooved discs are slidably connected to the hollow plate. Multiple rotating wheels are rotatably connected to the center of the inner side of the movable plate. The rotating wheels are connected to the grooved discs via a belt.

[0009] Furthermore, the mounting mechanism includes a base disposed on the lower side of the mounting plate. A second dual-head motor is fixedly connected to the top center of the base. One side of the second dual-head motor passes through the base and is fixedly connected to a second gear. Toothed rings are rotatably connected to the inner perimeter of the base. The toothed rings mesh with the second gear. A threaded pin is threadedly connected to the inner side of the toothed ring. The outer side of the threaded pin is slidably connected to the base. A plug pin is fixedly connected to the bottom of the threaded pin. A lifting assembly is provided on the top of the base.

[0010] Furthermore, the positioning component includes a sliding block, with two sliding blocks slidably connected to the outer left and right sides of the U-shaped frame, and multiple slots are provided on the top outer side of the mounting plate, with the sliding blocks engaging with the corresponding slots.

[0011] Furthermore, the handling assembly includes handles, with two handles respectively disposed on the outer left and right sides of the mounting plate. Screws are threadedly connected to the upper and lower sides of the inner sides of the handles, and the handles are threadedly connected to the mounting plate through the screws.

[0012] Furthermore, the angle adjustment mechanism also includes a bracket, which is fixedly connected to the outside of the rack, and the top of the bracket is fixedly connected to the U-shaped block.

[0013] Furthermore, the support mechanism also includes knobs, two of which are rotatably connected to the bottom center of the movable plate, and the top of the knobs passes through the movable plate and is fixedly connected to the corresponding rotating wheel.

[0014] Furthermore, the lifting assembly includes a threaded column, which is fixedly connected to the upper side of the base. The other side of the second dual-head motor passes through the base and is fixedly connected to a threaded cover. The threaded cover is threadedly connected to the mounting plate, and the mounting plate is slidably connected to the threaded column.

[0015] Furthermore, the mounting mechanism also includes protective covers, with multiple protective covers fixedly connected to the outer bottom perimeter of the threaded column, and the bottom of the protective covers fixedly connected to the base; a controller is fixedly connected to the front side of the mounting plate, and the controller is electrically connected to the first dual-head motor and the second dual-head motor respectively.

[0016] A construction method for a modular formwork support frame for post-pouring strips includes the following steps:

[0017] S1. When the first gear rotates, it will drive the rack meshing with it and the U-shaped block connected to it to move up and down synchronously. During the movement, the U-shaped block and the telescopic plate can rotate relative to each other. At the same time, the telescopic plate itself can also extend and retract. With the help of the rotation of the U-shaped block and the extension and retraction of the telescopic plate, the position of the floor can be precisely adjusted. In addition, the angle of the entire device can be further adjusted by rotating the U-shaped frame along the mounting plate.

[0018] S2. When the first dual-head motor is started, the threaded rod begins to rotate. The rotation of the threaded rod further drives the hollow plate to move. When the hollow plate moves, relative sliding occurs between it and the grooved plate. This sliding action causes the moving plate to move as well. The movement of the moving plate can increase the unfolded area and support area of ​​the device, thereby improving its stability and load-bearing capacity. At the same time, the rotating wheel starts to rotate and transmits power to the grooved plate through the belt, driving the grooved plate to rotate. By controlling the rotation of the rotating wheel, the rotation state of the grooved plate can be indirectly adjusted, thereby achieving precise control of the unfolding degree of the moving plate.

[0019] S3. When the second dual-head motor is turned on, its power output causes the second gear to start rotating. During the rotation of the second gear, it will synchronously drive the multiple toothed rings that mesh with it to rotate together. As the toothed rings continue to rotate, they will drive the threaded pins to rotate and move axially. Since the plug pins are installed on the threaded pins, the plug pins will move up and down along the trajectory set by the base together with the threaded pins. With the help of this movement method, the plugging and fixing operation of the device can be completed quickly.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. When the specified gear is rotated, the gear meshes with the rack, thereby driving the rack and the U-shaped block mounted on the rack to move up and down. By utilizing the rotational connection between the U-shaped block and the telescopic plate, and combined with the telescopic plate's telescopic characteristics, the position of the floor slab can be adjusted. By allowing the U-shaped frame to rotate along the mounting plate, the overall angle of the device can also be adjusted, thereby improving the reliability of the device.

[0022] 2. This invention activates a first dual-head motor, whose output shaft drives a threaded rod to rotate. The rotation of the threaded rod, through threaded transmission, causes the hollow plate to move. During this movement, the hollow plate slides against the grooved disc, causing the movable plate to move as well. This movement increases the device's unfolding range and enhances its support capacity, thereby increasing the device's unfolding and support area. The rotation of the rotating wheel drives a belt, which in turn transmits power to another grooved disc, adjusting its rotation state. This allows for precise control of the movable plate's unfolding extent, thus improving the device's convenience.

[0023] 3. After the second dual-head motor is started, the output shaft of the motor will drive the second gear to start rotating. While the second gear is rotating, it will drive multiple toothed rings that mesh with it to rotate together. As the toothed rings rotate, they will interact with the threaded pins, causing the threaded pins and the plug pins installed on the threaded pins to move up and down along the preset path of the base. With the help of this up and down movement, the device can be quickly and conveniently plugged in and fixed, thereby improving the practicality of the device. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] See Figure 3 , Figure 4 and Figure 6 This invention provides a modular formwork support frame for post-pouring strips, including a mounting plate 1, an angle adjustment mechanism 2 on the outer side of the mounting plate 1 for adjusting the support angle, a support mechanism 3 on the top of the mounting plate 1 for adjusting the support area, and a mounting mechanism 4 on the bottom of the mounting plate 1 for supporting and adjusting the device.

[0035] The angle adjustment mechanism 2 includes a U-shaped frame 21, which is rotatably connected to the upper side of the mounting plate 1. A first gear 22 is rotatably connected to the middle of the inner side of the U-shaped frame 21. The first gear 22 can rotate along the inside of the U-shaped frame 21. A rack 23 is slidably connected to both the left and right sides of the inside of the U-shaped frame 21. The rack 23 is slidably connected to the first gear 22. A U-shaped block 24 is fixedly connected to the top of the rack 23. Rotating the first gear 22 can drive the rack 23 and the U-shaped block 24 to move up and down. A telescopic plate 25 is rotatably connected to the inner side of the U-shaped block 24. A floor 26 is fixedly connected to the top of the telescopic plate 25. The angle of the floor 26 can be adjusted by the extension and retraction of the telescopic plate 25 and the rotation of the U-shaped block 24. A positioning component 27 is provided on the inner side of the U-shaped frame 21, and a conveying component 28 is provided on the outer side of the mounting plate 1.

[0036] Specifically, by rotating the first gear 22, the rack 23 and the U-shaped block 24 on it can be moved up and down. The position of the floor slab 26 can be adjusted by rotating the U-shaped block 24 and the telescopic plate 25, and by telescopically extending and retracting the telescopic plate 25 itself. At the same time, by rotating the U-shaped frame 21 along the mounting plate 1, the angle of the device can be further adjusted.

[0037] See Figure 1 , Figure 2 and Figure 7 The support mechanism 3 includes a first dual-head motor 31 and a belt 36. The first dual-head motor 31 is fixedly connected to the inner side of the floor slab 26. Threaded rods 32 are fixedly connected to the front and rear sides of the first dual-head motor 31. The outer side of the threaded rods 32 passes through the floor slab 26 and is threadedly connected to a hollow plate 33. Starting the first dual-head motor 31 can drive the threaded rods 32 to rotate and push the hollow plate 33 to move. Movable plates 37 are provided on the left and right sides inside the hollow plate 33. Grooved disks 34 are rotatably connected to the front and rear sides inside the movable plates 37. The grooved disks 34 are slidably connected to the hollow plate 33. Multiple rotating wheels 35 are rotatably connected to the middle of the inner side of the movable plates 37. The rotating wheels 35 are connected to the grooved disks 34 through the belt 36. Through the transmission of the belt 36, the grooved disks 34 can be driven to rotate when the rotating wheels 35 rotate.

[0038] Specifically, by starting the first dual-head motor 31, the threaded rod 32 can be rotated, thereby moving the hollow plate 33. At this time, as the hollow plate 33 moves and the grooved plate 34 slides, the moving plate 37 moves, increasing the unfolding and support area. At the same time, the rotation of the rotating wheel 35 drives the belt 36 to adjust the rotation of the grooved plate 34, thereby controlling the unfolding of the moving plate 37.

[0039] See Figure 1 , Figure 2 and Figure 8 The mounting mechanism 4 includes a base 45, which is located on the lower side of the mounting plate 1. A second double-head motor 41 is fixedly connected to the top center of the base 45. One side of the second double-head motor 41 passes through the base 45 and is fixedly connected to a second gear 42. Starting the second double-head motor 41 will drive the second gear 42 to rotate. Toothed rings 43 are rotatably connected to the inside of the base 45. The toothed rings 43 are meshed with the second gear 42. The rotation of the second gear 42 will drive the toothed rings 43 to rotate. A threaded pin 44 is threadedly connected to the inner side of the toothed ring 43. Rotating the toothed ring 43 can drive the threaded pin 44 to move up and down. The outer side of the threaded pin 44 is slidably connected to the base 45. A plug pin 46 is fixedly connected to the bottom of the threaded pin 44. When the threaded pin 44 moves, the device can be fixed through the plug pin 46. A lifting assembly 47 is provided on the top of the base 45.

[0040] Specifically, by starting the second dual-head motor 41, the second gear 42 can be driven to rotate, and at the same time, multiple toothed rings 43 meshing with it can be driven to rotate. At this time, as the toothed rings 43 rotate, the threaded pins 44 and the insertion pins 46 on them can be driven to move up and down along the base 45, so as to quickly insert and fix the device.

[0041] See Figure 3 , Figure 4 and Figure 6 The positioning component 27 includes a sliding block 271, with two sliding blocks 271 slidably connected to the left and right sides of the U-shaped frame 21. Multiple slots 272 are provided on the top of the outer side of the mounting plate 1. The sliding blocks 271 engage with the corresponding slots 272. When the U-shaped frame 21 is rotated, the engagement of the sliding blocks 271 with the slots 272 positions the U-shaped frame 21. The conveying component 28 includes a handle 281, with two handles 281 respectively located on the left and right sides of the mounting plate 1. Screws 282 are threaded onto the upper and lower sides of the handle 281. The handle 281 is threaded to the mounting plate 1 via the screws 282. Holding the handle 281 facilitates gripping and conveying the device, while the screws 282 allow for easy installation and removal as needed. The angle adjustment mechanism 2 also includes a bracket 29, which is fixedly connected to the outer side of the rack 23. The top of the bracket 29 is fixedly connected to the U-shaped block 24. The bracket 29 enhances the support strength of the rack 23 and the U-shaped block 24.

[0042] Specifically, after the U-shaped frame 21 is rotated to the appropriate position, the sliding block 271 is moved along the U-shaped frame 21 to engage with the slot 272, so as to position the U-shaped block 24. The detachable handle 281 installed by the screw 282 makes it easy to hold and operate the device for handling and moving. The bracket 29 can improve the firmness of the installation between the rack 23 and the U-shaped block 24.

[0043] See Figure 2 , Figure 3 and Figure 7 The support mechanism 3 also includes knobs 38. Two knobs 38 are rotatably connected to the bottom center of the movable plate 37. The top of the knobs 38 passes through the movable plate 37 and is fixedly connected to the corresponding rotating wheel 35. Rotating the knobs 38 will synchronously drive the rotating wheel 35 to rotate. A controller 5 is fixedly connected to the front side of the mounting plate 1. The controller 5 is electrically connected to the first dual-head motor 31 and the second dual-head motor 41 respectively. The controller 5 can operate the switches of the first dual-head motor 31 and the second dual-head motor 41 respectively.

[0044] Specifically, rotating the knob 38 can easily drive the rotating wheel 35 to rotate, and the controller 5 can easily control the start-up and operation of the first dual-head motor 31 and the second dual-head motor 41 respectively.

[0045] See Figure 3 , Figure 5 and Figure 8 The lifting assembly 47 includes a threaded post 471, which is fixedly connected to the upper side of the base 45. The other side of the second dual-head motor 41 passes through the base 45 and is fixedly connected to a threaded cover 472. The threaded cover 472 is threadedly connected to the mounting plate 1. When the second dual-head motor 41 is started, it drives the threaded post 471 to rotate to adjust the height of the mounting plate 1. The mounting plate 1 is slidably connected to the threaded post 471. The mounting mechanism 4 also includes a protective cover 48. Multiple protective covers 48 are fixedly connected to the bottom of the outer side of the threaded post 471. The bottom of the protective cover 48 is fixedly connected to the base 45. The protective cover 48 can easily support the base 45 and protect the base 45.

[0046] Specifically, by starting the second dual-head motor 41, the threaded column 471 can be rotated, thereby causing the mounting plate 1 to move up and down along the threaded column 471 to adjust the height of the device. The protective cover 48 can protect the base 45.

[0047] Working principle: When the first gear 22 rotates, it drives the meshing rack 23 and the U-shaped block 24 connected to it to move up and down synchronously. During the movement, the U-shaped block 24 and the telescopic plate 25 can rotate relative to each other, and the telescopic plate 25 itself can also extend and retract. With the help of the rotation of the U-shaped block 24 and the extension and retraction of the telescopic plate 25, the position of the floor slab 26 can be precisely adjusted. In addition, the angle of the entire device can be further adjusted by rotating the U-shaped frame 21 along the mounting plate 1. When the first double-headed motor 31 is started, it drives the threaded rod 32 to start rotating. The rotation of the threaded rod 32 further drives the hollow plate 33 to move. When the hollow plate 33 moves, it slides relative to the grooved plate 34. This sliding action causes the moving plate 37 to move as well. The movement of the moving plate 37 can increase the unfolded area of ​​the device and support. The support area is increased, thereby improving its stability and load-bearing capacity. At the same time, the rotating wheel 35 starts to rotate and transmits power to the grooved plate 34 through the belt 36, causing the grooved plate 34 to rotate. By controlling the rotation of the rotating wheel 35, the rotation state of the grooved plate 34 can be indirectly adjusted, thereby achieving precise control of the unfolding degree of the moving plate 37. When the second double-head motor 41 is turned on, its power output causes the second gear 42 to start rotating. During the rotation of the second gear 42, it will synchronously drive the multiple toothed rings 43 that mesh with it to rotate together. As the toothed rings 43 continue to rotate, they will drive the threaded pins 44 to rotate and move axially. Since the insertion pins 46 are installed on the threaded pins 44, the insertion pins 46 will move up and down along the trajectory set by the base 45 together with the threaded pins 44. With the help of this movement method, the insertion and fixing operation of the device can be completed quickly.

This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.

The movement of the moving plate (37) can increase the unfolded area and support area of ​​the device, thereby improving its stability and load-bearing capacity. At the same time, the rotating wheel (35) starts to rotate and transmits power to the grooved plate (34) through the belt (36), driving the grooved plate (34) to rotate. By controlling the rotation of the rotating wheel (35), the rotation state of the grooved plate (34) can be indirectly adjusted, thereby achieving precise control of the unfolding degree of the moving plate (37). S3. When the second dual-head motor (41) is turned on, its power output causes the second gear (42) to start rotating. During the rotation of the second gear (42), it will drive the multiple toothed rings (43) that mesh with it to rotate together. As the toothed rings (43) continue to rotate, they will drive the threaded pins (44) to rotate and move along the axial direction. Since the plug pins (46) are installed on the threaded pins (44), the plug pins (46) will move up and down along the trajectory set by the base (45) together with the threaded pins (44). With the help of this movement, the plugging and fixing operation of the device can be completed quickly.
