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

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. When using construction formwork, devices are needed to support it. Formwork support devices are equipment used to support and fix construction formwork to ensure the stability and accuracy of the formwork during construction.

[0003] Chinese utility model patent application number 202420891098.3 provides a building formwork support device. By setting a movable adjusting arm, the height of the fixed clamping plate and the movable clamping plate can be adjusted to support the formwork body of different heights. Furthermore, by rotating the adjusting screw, the position of the movable clamping plate can be adjusted to clamp the formwork body of different thicknesses, thereby ensuring the stability of the device in supporting the formwork body and improving the practicality and applicability of the device.

[0004] However, during the use of the above-mentioned equipment, it was found that by setting extension block one and extension block two, the support plates on both sides of the equipment can be connected. However, extension block one and extension block two are hinged to each other. For situations where the shape and angle of the template need to be precisely adjusted, the movable characteristics of the hinge structure can easily make it difficult to guarantee the adjustment accuracy, thereby affecting the manufacturing accuracy of the template and the quality of the final product. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a building formwork support device, which solves the problem mentioned in the background art that, in situations requiring precise adjustment of the formwork shape and angle, the movable characteristics of the hinged structure easily lead to difficulties in ensuring adjustment accuracy, thereby affecting the manufacturing precision of the formwork and the quality of the final product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building formwork support device, comprising a support plate, a lifting frame vertically slidably mounted in the support plate, a clamping mechanism provided on the lifting frame, mounting grooves at both ends of the support plate, an extension member installed in the mounting groove, the extension member being connected to a connecting member, the connecting member comprising a first extension block and a second extension block, the first extension block and the second extension block being hinged together, an adjusting frame fixedly mounted on the top of the first extension block, a worm gear rotatably mounted in the adjusting frame, a handle provided at one end of the worm gear, a worm wheel meshing on one side of the worm gear, the worm wheel being fixedly mounted on a fixed shaft, and the fixed shaft being fixed to the top of the second extension block.

[0007] Preferably, the adjusting frame has a through hole, an angle gauge is provided around the through hole, the top of the fixed shaft is located in the through hole, and a pointer is fixedly provided on the top of the fixed shaft.

[0008] Preferably, the extension member includes a connecting arm, and connecting grooves are provided on both the front and rear sides of the connecting arm. The connecting arm is connected to the connecting member through the connecting grooves. An extension arm is fixedly installed on the side of the connecting arm away from the connecting arm, and connecting holes are provided on the extension arm in an equidistant array.

[0009] Preferably, the extension arm is adapted to the mounting groove, and the extension arm is slidably mounted in the mounting groove.

[0010] Preferably, a limiting frame is fixedly installed on one end of the mounting groove near the extension member. The inner side of the limiting frame is connected to the limiting plate by a spring. A pull rod and a limiting rod are respectively connected to both sides of the limiting plate. The limiting rod passes through the limiting frame and is adapted to the connecting hole. The pull rod is fixedly connected to the pull handle.

[0011] Preferably, support rods are connected to both outer ends of the support plate and to the outer side of the connecting arm.

[0012] This utility model provides a building formwork support device. It has the following beneficial effects:

[0013] (1) This utility model uses the meshing transmission of worm and worm wheel to control the angle change between the first extension block and the second extension block. Since the worm and worm wheel transmission has self-locking and high transmission accuracy, it can adjust the angle more precisely, thereby improving the adjustment accuracy of the template shape and angle, which helps to ensure the manufacturing accuracy of the template and the quality of the final product.

[0014] (2) By setting a pointer and an angle table, the operator can directly read the angle value from the angle table to accurately understand the rotation angle of the second extension block relative to the first extension block, and thus understand the adjustment of the template angle, which helps to improve the accuracy and efficiency of angle adjustment.

[0015] (3) By setting up components such as extension arms, mounting grooves and limiting rods, this utility model can change the overall length of the support plate by pulling the extension arms out or pushing them into the mounting groove, so as to adapt to the support requirements of templates of different sizes, thereby improving the versatility and applicability of the template support device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] Please see Figures 1-4 This utility model provides a building formwork support device, including a support plate 1, a lifting frame 11 vertically slidably installed in the support plate 1, a clamping mechanism 12 provided on the lifting frame 11, and mounting grooves 13 opened at both ends of the support plate 1. An extension member 3 is installed in the mounting groove 13 and connected to a connecting member 2. The connecting member 2 includes a first extension block 21 and a second extension block 22, which are hinged together. An adjusting frame 211 is fixedly installed on the top of the first extension block 21, and a worm gear 214 is rotatably installed in the adjusting frame 211. A handle 215 is provided at one end of the worm gear 214, and a worm wheel 222 is engaged on one side of the worm gear 214. The worm wheel 222 is fixedly installed on a fixed shaft 221, and the fixed shaft 221 is fixed on the top of the second extension block 22.

[0030] Specifically, the lifting frame 11 in the device includes components such as adjusting arms, fixing bolts, and adjusting screws. The specific structure has been described in detail in the referenced documents. It is mainly used to adjust the height and cooperate with the clamping mechanism 12 to adapt and fix the template body.

[0031] When connecting multiple support plates 1, the handle 215 at one end of the worm 214 is rotated. The rotation of the worm 214 drives the worm wheel 222 that meshes with it to rotate. Since the worm wheel 222 is fixedly installed on the fixed shaft 221, and the fixed shaft 221 is fixed to the top of the second extension block 22, the rotation of the worm wheel 222 will drive the second extension block 22 to rotate around the fixed shaft 221 relative to the first extension block 21, thereby realizing the adjustment of the angle between the two extension blocks, and thus realizing the angle adjustment between multiple support plates 1 connected by the connector 2.

[0032] The worm gear 214 and worm wheel 222 transmission has high transmission accuracy and can achieve more precise angle adjustment. Compared with a simple hinge structure, the operator can precisely control the rotation angle of the second extension block 22 by rotating the worm gear 214, thereby meeting the precise adjustment requirements of different template shapes and angles, which helps to improve the manufacturing accuracy of the template and the quality of the final product.

[0033] Meanwhile, the worm gear 214 and worm wheel 222 transmission has a self-locking characteristic, that is, under certain conditions, only the worm gear 214 can drive the worm wheel 222 to rotate, while the worm wheel 222 cannot drive the worm gear 214 to rotate. This makes it possible for the second extension block 22 to remain at the set angle position even when subjected to external force after being adjusted to a suitable angle, and it is not easy for the angle to change. This enhances the stability and reliability of the template support device during use and ensures the accuracy of the template angle.

[0034] Furthermore, to ensure the accuracy of angle adjustment, please refer to [link / reference needed]. Figures 1-5 The adjusting bracket 211 has a through hole 212, and an angle gauge 213 is provided around the through hole 212. The top of the fixed shaft 221 is located in the through hole 212, and a pointer 223 is fixedly provided on the top of the fixed shaft 221.

[0035] Specifically, when the worm gear 222 drives the fixed shaft 221 and the second extension block 22 to rotate, the pointer 223 will rotate along with the fixed shaft 221. The operator can accurately read the angle change value according to the indication of the pointer 223 on the angle meter 213, thereby accurately controlling the rotation angle of the second extension block 22 relative to the first extension block 21 and achieving the accuracy of angle adjustment.

[0036] The combination of angle gauge 213 and pointer 223 provides operators with an intuitive angle display, accurate to a specific angle value. This allows operators to adjust the angle without relying on experience or vague visual judgment, but rather with a clear numerical reference, greatly improving the accuracy of angle adjustment.

[0037] Furthermore, to improve the adaptability of support plate 1 to template bodies of different lengths, please refer to... Figures 1-6 The extension member 3 includes a connecting arm 31. Connecting grooves 32 are provided on both the front and rear sides of the connecting arm 31. The connecting arm 31 is connected to the connector 2 through the connecting grooves 32. An extension arm 33 is fixedly installed on the side of the connecting arm 31 away from the connecting arm 31. Connecting holes 34 are provided on the extension arm 33 in an equidistant array.

[0038] The extension arm 33 is adapted to the mounting groove 13, and the extension arm 33 is slidably installed in the mounting groove 13;

[0039] A limit frame 14 is fixedly installed on one end of the mounting slot 13 near the extension 3. The inner side of the limit frame 14 is connected to the limit plate 151 by a spring 16. A pull rod 15 and a limit rod 152 are respectively connected to the two sides of the limit plate 151. The limit rod 152 passes through the limit frame 14 and is adapted to the corresponding connection hole 34. The pull rod 15 is fixedly connected to the pull handle 17.

[0040] Support rods 4 are connected to both ends of the outer side of the support plate 1 and to the outer side of the connecting arm 31.

[0041] Specifically, the extension arm 33 is adapted to the mounting groove 13 and is slidably installed in the mounting groove 13. According to the length requirements of the template body, the extension arm 33 can be slid out of the mounting groove 13 by an appropriate length, thereby increasing the overall effective support length of the support plate 1.

[0042] When it is necessary to adjust the extension length of the extension arm 33, pull the handle 17. The handle 17 drives the pull rod 15. The pull rod 15 causes the limiting plate 151 to compress the spring 16, thereby causing the limiting rod 152 to disengage from the connecting hole 34. At this time, the extension arm 33 can be slid to the appropriate position. Then release the handle 17. The spring 16 pushes the limiting plate 151 to insert the limiting rod 152 into the corresponding connecting hole 34, thereby fixing the position of the extension arm 33 to adapt to template bodies of different lengths.

[0043] By flexibly adjusting the length of the support plate 1, both shorter and longer templates can be effectively supported by adjusting the extension length of the extension arm 33. This greatly improves the adaptability of the support plate 1 to template bodies of different lengths, reduces the need to replace support devices of different specifications due to different template lengths, and improves the versatility of the equipment.

[0044] The support rod 4 is connected to both ends of the outer side of the support plate 1 and the outer side of the connecting arm 31. When the extension arm 33 is extended, the support rod 4 can provide additional support force for the extension arm 33 and the support plate 1, so that the entire support device can maintain good stability when supporting templates of different lengths. This avoids deformation or shaking of the support device due to the extension arm 33 extending too far or uneven weight distribution of the template, thus ensuring the stability and safety of the template during construction.

[0045] Working principle: Based on the length of the template body, determine whether the extension piece 3 is needed to adjust the length of the support plate 1. If the template is too long, pull the handle 17 to disengage the limiting rod 152 from the connecting hole 34, slide the extension arm 33 out of the mounting groove 13 to an appropriate length to increase the overall effective support length of the support plate 1, and then release the handle 17 to insert the limiting rod 152 into the corresponding connecting hole 34 to fix the position of the extension arm 33;

[0046] Multiple support plates 1 are connected by connectors 2. Rotating the handle 215 at one end of the worm 214 causes the worm 214 to drive the worm wheel 222 to rotate, which in turn drives the second extension block 22 to rotate relative to the first extension block 21 around the fixed axis 221, thereby achieving angle adjustment. By observing the indication of the pointer 223 on the angle gauge 213, the angle change value can be precisely controlled to meet the requirements of different template shapes and angles.

[0047] Then, based on the height of the template body, the height of the lifting frame 11 is adjusted by the adjusting arm, fixing bolt, adjusting screw and other components in the lifting frame 11 so that the clamping mechanism 12 can be adapted to the height position of the template body. Then, the clamping mechanism 12 is used to fix the template body on the support plate 1 to complete the installation and fixing of the template.

[0048] Finally, support rod 4 unfolds to provide additional support for the entire support device, enhancing stability.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
