Description

Technical Field

[0001] This utility model relates to the field of building formwork support technology, and specifically to a building formwork support device. Background Technology

[0002] In building construction, formwork support systems are crucial for ensuring the quality of concrete pouring. Their main function is to bear the loads of the formwork and during the pouring process, ensuring precise structural dimensions. Currently, traditional support systems often employ a simple structure with a single upright and horizontal bar, generally lacking auxiliary fixing mechanisms. For example, the connection between the upright and the ground often relies on a simple base, secured only by gravity or a few bolts, which is prone to loosening under the lateral forces generated by vibrating concrete. The joints between the upright and horizontal bars are also mostly plug-in or single-bolt connections, which are insufficient to withstand multi-directional loads. This lack of secure fixing leads to insufficient stability of the support system, especially during high-rise pouring or large-area operations. Uneven load distribution can easily cause overall tilting or even collapse, affecting construction progress and seriously threatening the safety of construction workers.

[0003] Patent publication number CN221546508U discloses a building formwork support device, including a support rod. A support plate is fixedly installed at the upper end of the support rod. An adjustment structure is provided on one side of the support plate. The adjustment structure includes a storage plate and a splicing plate. The storage plate and the splicing plate are rotatably connected to the two sides of the support plate, respectively. A lead screw is provided inside the support rod. A slider is threaded on the outer wall of the lead screw. Sleeves are fixedly connected to both sides of the slider through the two sides of the support rod. Connecting rods are fixedly installed on both sides of the sleeves. A contact plate is fixedly installed at the lower middle part of the storage plate. An adjustment groove is opened on the front side of the lower end of the support rod.

[0004] The above-mentioned device uses a single support rod to directly support the building formwork, but it is not always secure enough, which can lead to the formwork tipping over during the pouring process. Utility Model Content

[0005] The purpose of this utility model is to provide a building formwork support device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A building formwork support device includes a fixed base, a sleeve inserted inside the fixed base, a connecting block fixedly connected to the top of the sleeve, a support screw threaded inside the sleeve, and a connecting bolt inserted into the bottom of the fixed base, the connecting bolt passing through the fixed base and threadedly connected to the sleeve.

[0008] It also includes a support plate, a drive mechanism, an auxiliary support mechanism, and a base.

[0009] The support plate is set on top of the support screw to support the building formwork;

[0010] The drive mechanism is located at the connection between the sleeve and the support screw, and is used to adjust and fix the height of the device;

[0011] The auxiliary support mechanism is located on the side of the sleeve to improve the stability of the device;

[0012] The base is located at the bottom of the fixed seat and is used to fix the device to the ground.

[0013] A further improvement of the present invention is that the driving mechanism includes a driving block, the driving block is rotatably connected to the top of the connecting block, the driving block has an internal thread that cooperates with the support screw, the support screw is threadedly connected to the inside of the driving block, a rotating rod is fixedly connected to the surface of the driving block, and a limit screw is threadedly connected to the top of the driving block, the limit screw passes through the driving block and contacts the top of the connecting block.

[0014] A further improvement of the present invention is that: the fixed base is fixedly connected to the outside of the fixed base, the fixed ear is fixedly connected to the side of the fixed base, the fixed bolt is inserted into the inside of the fixed ear, and the top of the fixed base is provided with a sliding groove.

[0015] A further improvement of this utility model is that: the auxiliary support mechanism includes a hinge block, the hinge block is fixedly connected to the side of the support screw, the hinge block is distributed in a circumferential array on the side of the connecting block, a telescopic diagonal rod is hinged inside the hinge block, a compression sleeve is rotatably connected to the middle of the telescopic diagonal rod, the compression sleeve is made of elastic material, a threaded sleeve is threadedly connected to the outside of the compression sleeve, and the inner diameter of the threaded sleeve gradually decreases from bottom to top.

[0016] A further improvement of the present invention is that the auxiliary support mechanism further includes a slider and a limiting hole. The limiting hole is opened inside the slide groove. The slider is slidably connected inside the slide groove. The telescopic diagonal rod is hinged to the top of the slider. A fixing screw is inserted into the top of the slider. The fixing screw passes through the slider and is threadedly connected to the limiting hole.

[0017] A support plate is fixedly connected to the top of the support screw, and anti-slip protrusions are fixedly connected to the top of the support plate. The anti-slip protrusions are evenly distributed on the top of the support plate.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model provides a building formwork support device. A sleeve is inserted into the interior of a fixed base and then fixed with connecting bolts. After fixing, a rotating drive mechanism extends the device to a suitable length and fixes it. The device is then placed at the bottom of the building formwork, allowing the support plate to contact it. An auxiliary support mechanism is then fixed to the base. The position of the device is then fine-tuned, and finally, the device is fixed to the ground via the base. By adjusting the position of the connection between the auxiliary support mechanism and the base, the tilt angle of the auxiliary support mechanism can be adjusted. When the tilt angle is too small, the horizontal component force is insufficient, the load on the ground fixing point is too high, and the anti-overturning ability is weak. When the tilt angle is too large, the horizontal component force gain is limited, which can easily lead to pressure on the uprights or loosening of the foundation. This device can adjust to a suitable tilt angle, thereby improving the overall stability of the device.

[0020] 2. This utility model provides a building formwork support device. A sleeve is inserted into a fixed base and then fixed with connecting bolts. After fixing, rotating the rotating rod drives the drive block to rotate, causing the support screw to extend upwards. Then, tightening the limiting screws fixes the position of the drive block through the friction between the limiting screws and the connecting block. After adjusting to a suitable length, the device is placed at the bottom of the building formwork. Further fine-tuning of the drive block ensures full contact between the support plate and the building formwork. Anti-slip protrusions increase the friction between the device and the building formwork, preventing slippage. After adjustment, the base is fixed to the ground with fixing bolts to prevent the device from shifting during pouring.

[0021] 3. This utility model provides a building formwork support device. By loosening the threaded sleeve, inserting the extrusion sleeve into the inside of the slide groove, adjusting it to a suitable position, fixing the slider with fixing screws and limiting holes, and then tightening the threaded sleeve, the extrusion sleeve is deformed by the threaded sleeve pressing the extrusion sleeve, thereby compressing the telescopic diagonal rod and fixing the length of the telescopic diagonal rod. After the device is used, the slider is separated from the slide groove, and the connecting bolts are removed to disassemble the device for easy transportation and storage.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figure 1-6 As shown, this utility model has the following three specific embodiments.

[0037] Example 1

[0038] This utility model provides a building formwork support device, including a fixed base 11, a sleeve 12 inserted inside the fixed base 11, a connecting block 14 fixedly connected to the top of the sleeve 12, a support screw 13 threadedly connected inside the sleeve 12, and a connecting bolt 15 inserted at the bottom of the fixed base 11, the connecting bolt 15 passing through the fixed base 11 and threadedly connected to the sleeve 12.

[0039] It also includes a support plate 21, a drive mechanism 3, an auxiliary support mechanism 4, and a base 51.

[0040] The support plate 21 is set on top of the support screw 13 to support the building formwork;

[0041] The drive mechanism 3 is located at the connection between the sleeve 12 and the support screw 13, and is used to adjust and fix the height of the device.

[0042] The auxiliary support mechanism 4 is located on the side of the sleeve 12 to improve the stability of the device;

[0043] The base 51 is located at the bottom of the fixed base 11 and is used to fix the device to the ground.

[0044] In this embodiment, as Figure 1 and 5 As shown, the sleeve 12 is inserted into the inside of the fixed base 11 and then fixed with the connecting bolt 15. After fixing, the device is extended to a suitable length by rotating the drive mechanism 3 and fixed. Then, the device is placed at the bottom of the building formwork and the support plate 21 is brought into contact with it. Then, the auxiliary support mechanism 4 is fixed to the base 51. Then, the position of the device is finely adjusted, and then the device is fixed to the ground by the base 51. By adjusting the position of the connection between the auxiliary support mechanism 4 and the base 51, the tilt angle of the auxiliary support mechanism 4 can be adjusted. When the tilt angle is too small, the horizontal component force is insufficient, the load on the ground fixing point is too high, and the anti-overturning ability is weak. When the tilt angle is too large, the horizontal component force gain is limited, which can easily lead to the upright being compressed or the foundation loosening. This device can adjust to a suitable tilt angle, thereby improving the overall stability of the device.

[0045] Example 2

[0046] The difference from Embodiment 1 is that this embodiment discloses a support plate 21, a drive mechanism 3, and a base 51;

[0047] Preferably, the drive mechanism 3 includes a drive block 31, which is rotatably connected to the top of the connecting block 14. The drive block 31 has an internal thread that mates with the support screw 13. The support screw 13 is threadedly connected to the inside of the drive block 31. A rotating rod 32 is fixedly connected to the surface of the drive block 31. A limit screw 33 is threadedly connected to the top of the drive block 31. The limit screw 33 passes through the drive block 31 and contacts the top of the connecting block 14.

[0048] The fixed base 11 is externally fixedly connected to a base 51, and a fixed ear 52 is fixedly connected to the side of the base 51. A fixed bolt 54 is inserted into the fixed ear 52, and a sliding groove 53 is provided on the top of the base 51.

[0049] A support plate 21 is fixedly connected to the top of the support screw 13, and anti-slip protrusions 22 are fixedly connected to the top of the support plate 21. The anti-slip protrusions 22 are evenly distributed on the top of the support plate 21.

[0050] In this embodiment, as Figure 3 and 6 As shown, the sleeve 12 is inserted into the fixed base 11 and then fixed by the connecting bolt 15. After fixing, the rotating rod 32 is rotated to drive the drive block 31 to rotate, thereby driving the support screw 13 to extend upward. Then, the limit screw 33 is tightened, and the position of the drive block 31 is fixed by the friction between the limit screw 33 and the connecting block 14. After adjusting to a suitable length, the device is placed at the bottom of the building template. Then, the drive block 31 is finely adjusted to make the support plate 21 fully contact the building template. The anti-slip protrusion 22 can increase the friction between the device and the building template, thereby preventing the building template from sliding. After adjustment, the base 51 is fixed to the ground by the fixing bolt 54, thereby preventing the device from shifting during the pouring process.

[0051] Example 3

[0052] The difference from Embodiment 2 is that this embodiment discloses an auxiliary support mechanism 4;

[0053] Preferably, the auxiliary support mechanism 4 includes a hinge block 41, which is fixedly connected to the side of the support screw 13. The hinge blocks 41 are arranged in a circumferential array on the side of the connecting block 14. A telescopic diagonal rod 42 is hinged inside the hinge block 41. A compression sleeve 44 is rotatably connected to the middle of the telescopic diagonal rod 42. The compression sleeve 44 is made of elastic material. A threaded sleeve 43 is threadedly connected to the outside of the compression sleeve 44. The inner diameter of the threaded sleeve 43 gradually decreases from bottom to top.

[0054] The auxiliary support mechanism 4 also includes a slider 47 and a limiting hole 45. The limiting hole 45 is opened inside the slide groove 53. The slider 47 is slidably connected inside the slide groove 53. The telescopic diagonal rod 42 is hinged to the top of the slider 47. A fixing screw 46 is inserted into the top of the slider 47. The fixing screw 46 passes through the slider 47 and is threadedly connected to the limiting hole 45.

[0055] In this embodiment, as Figure 2 , 3As shown in Figures 4 and 6, by loosening the threaded sleeve 43, inserting the compression sleeve 44 into the inside of the slide groove 53, and adjusting it to a suitable position, the slider 47 is fixed by the fixing screw 46 and the limiting hole 45. Then, the threaded sleeve 43 is tightened, and the compression sleeve 44 is deformed by the threaded sleeve 43, thereby compressing the telescopic diagonal rod 42 and fixing the length of the telescopic diagonal rod 42. After the device is used, the slider 47 is separated from the slide groove 53, and the connecting bolt 15 is removed, thereby disassembling the device for easy transportation and storage.

[0056] The working principle of this utility model is as follows:

[0057] The sleeve 12 is inserted into the fixed base 11 and then fixed with the connecting bolt 15. After fixing, the rotating rod 32 is rotated to drive the drive block 31 to rotate, thereby causing the support screw 13 to extend upward. Then, the limit screw 33 is tightened, and the position of the drive block 31 is fixed by the friction between the limit screw 33 and the connecting block 14. After adjusting to a suitable length, the device is placed at the bottom of the building formwork. Then, the drive block 31 is finely adjusted to ensure that the support plate 21 is in full contact with the building formwork. The anti-slip protrusion 22 can increase the friction between the device and the building formwork, thereby preventing the building formwork from sliding. After adjustment, the base 51 is fixed with the fixing bolt 54. The device is fixed to the ground to prevent it from shifting during the pouring process. The threaded sleeve 43 is loosened, and the extrusion sleeve 44 is inserted into the slide groove 53. After adjusting to the appropriate position, the slider 47 is fixed by the fixing screw 46 and the limiting hole 45. Then the threaded sleeve 43 is tightened, and the extrusion sleeve 44 is deformed by the threaded sleeve 43, which in turn extrudes the telescopic diagonal rod 42, thereby fixing the length of the telescopic diagonal rod 42. After the device is used, the slider 47 is separated from the slide groove 53, and the connecting bolt 15 is removed to disassemble the device for easy transportation and storage.

[0058] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
