Description

Technical Field

[0001] This utility model relates to the field of building construction equipment, specifically a multi-directional adjustable support pole structure for building construction templates. Background Technology

[0002] In building construction, formwork support frames are crucial temporary facilities for ensuring the accuracy of concrete component forming and construction safety. Traditional support frames have limited height and angle adjustment capabilities, making it difficult to adapt to complex and varied structural shapes and construction conditions. This can easily lead to problems such as incomplete formwork fit and inaccurate force transmission, thus affecting construction quality and efficiency. Therefore, a flexible and reliable multi-directional adjustment frame structure is needed to achieve precise and efficient support.

[0003] Existing formwork support frame upright structures typically employ a single screw or sleeve design for height adjustment, and provide limited angle adaptability through simple U-shaped brackets or movable hinges at the top. However, existing technical solutions have the following drawbacks in actual operation: (1) The angle adjustment mechanism at the top has a limited adjustment range and lacks an effective and reliable locking mechanism. It is prone to loosening when subjected to dynamic loads, resulting in changes in the preset angle and insufficient support stability. (2) The height adjustment and angle adjustment functions are independent of each other and the structure is not integrated enough. When making multiple or coordinated adjustments, the operation is cumbersome and affects the formwork efficiency. Utility Model Content

[0004] This utility model aims to provide a multi-directional adjustable support structure for building construction templates, mainly to solve the technical problems of poor locking reliability of hinged parts in the existing technology, which cannot maintain angular stability under vibration and load.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A multi-directional adjustable construction formwork support frame upright structure includes an outer upright, an inner upright inside the outer upright, a rotating adjustment component at the top of the inner upright, an external thread on the inner upright, and a first internal thread groove inside the outer upright. The inner upright and the outer upright are threaded together by the external thread and the first internal thread groove.

[0006] The working principle and beneficial effects of this utility model: 1. Working Principle: First, the overall height of the support structure is adjusted by rotating the inner upright through the threaded connection of the inner and outer uprights. Second, the top ball joint connection mechanism allows for flexible multi-angle adjustment of the support top to adapt to different template slopes. Finally, a liftable limit sleeve moves upward to apply a circumferential pressure to the ball joint mechanism, firmly locking it in the adjusted position and ensuring support stability.

[0007] 2. Beneficial effects: (1) The existing technology provides angle adaptability by setting up a movable hinge. However, the existing hinge has poor locking reliability and cannot maintain angle stability under vibration and load. This solution solves the technical problems of insufficient locking force of the angle adjustment mechanism and easy loosening under construction load by setting up a ball joint connection mechanism composed of a rotating sleeve, a cup-shaped cavity, a first anti-slip pad and a rotating ball head, and cooperating with a mechanical compression locking mechanism composed of a rotating sleeve, a limiting sleeve and a second anti-slip pad. This achieves a firm lock after multi-directional flexible adjustment.

[0008] (2) This solution integrates the height adjustment function and the multi-directional angle adjustment function into a coherent system by setting up the threaded lifting structure of the inner and outer uprights and the rotation adjustment component integrated at the top of the inner upright. This solves the technical problems of the separation of the two adjustment functions, poor operation coordination and low efficiency of the traditional support frame, and realizes that the height and angle can be quickly and accurately adjusted in a coordinated manner through a single upright structure.

[0009] Preferably, the inner upright has a sliding groove, and a limit block is slidably connected in the sliding groove. A connecting rod is fixedly connected to the bottom end of the limit block. The connecting rod passes through the bottom end of the inner upright and extends into the outer upright. The cooperation between the sliding groove in the inner upright, the limit block, and the connecting rod enables the inner upright to maintain stable movement when it is rotated and raised by the thread. The connecting rod is fixed to the base to prevent the inner upright from detaching during adjustment, ensuring that the raising and lowering process is smooth and controllable.

[0010] Preferably, the bottom end of the outer upright is fixedly connected to a base, the bottom end of the connecting rod is fixedly connected to the top surface of the base, a reinforcing rib is provided between the base and the outer upright, and an installation hole is provided on the base. The base is fixed to the ground or a support structure through the installation hole, providing a stable foundation for the entire support frame. The reinforcing rib enhances the connection strength between the base and the outer upright, reduces the risk of deformation, and improves the load-bearing capacity and safety of the overall structure.

[0011] Preferably, the rotation adjustment assembly includes a lower connecting block located above the inner upright. The bottom end of the lower connecting block is fixedly connected to the top end of the inner upright. A rotating sleeve is fixedly connected to the top end of the lower connecting block. The rotating sleeve has two clearance grooves and a bowl-shaped cavity. The rotating sleeve is bowl-shaped. A first anti-slip pad is fixedly connected to the inner wall of the rotating sleeve. The first anti-slip pad is irregularly shaped and its shape matches the bowl-shaped cavity. A rotating ball head is provided in the bowl-shaped cavity and is rotatably connected to the first anti-slip pad. An upper connecting block is fixedly connected to the top end of the rotating ball head. The rotation adjustment assembly achieves flexible angle adjustment of the upper connecting block in multiple directions through the cooperation of the rotating ball head and the bowl-shaped cavity. The first anti-slip pad provides sufficient frictional resistance in the bowl-shaped cavity, allowing smooth rotation while preventing accidental slippage, enabling the support frame to adapt to different construction angle requirements.

[0012] Preferably, a top support is fixedly connected to the top of the upper connecting block, and a reinforcing rib is provided between the top support and the upper connecting block. The top support has an installation hole, which is used to directly support the building construction formwork. The installation hole facilitates the fixing of the formwork or other components. The reinforcing rib increases the structural rigidity between the top support and the upper connecting block, ensuring the reliability and stability of the support under load.

[0013] Preferably, the inner upright is provided with a rotating sleeve, and the rotating sleeve has a second internal thread groove. The rotating sleeve and the inner upright are threadedly connected through the second internal thread groove and the first internal thread groove. A limiting sleeve is fixedly connected to the top end of the rotating sleeve. The diameter of the limiting sleeve is larger than the diameter of the rotating sleeve. When the rotating sleeve is rotated, it drives the limiting sleeve to move upward, applying pressure to the rotating sleeve, thereby squeezing the rotating ball head so that it cannot rotate, thus achieving the fixation and locking of the angle.

[0014] Preferably, a second anti-slip pad is fixedly connected to the inner wall of the limiting sleeve. The second anti-slip pad is made of rubber and provides additional frictional resistance when the limiting sleeve moves downward to compress the rotating sleeve, thereby enhancing the locking effect on the rotating ball head and preventing accidental movement or loosening after the angle is fixed.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 - Figure 4 As shown, the multi-directional adjustable construction formwork support frame upright structure includes an outer upright 1, an inner upright 2 inside the outer upright 1, a rotating adjustment component at the top of the inner upright 2, an external thread 4 on the inner upright 2, and a first internal thread groove 3 inside the outer upright 1. The inner upright 2 and the outer upright 1 are threadedly connected by the external thread 4 and the first internal thread groove 3. The outer upright 1 and the inner upright 2 form a spiral lifting mechanism through the cooperation of the external thread 4 and the first internal thread groove 3. Rotating the inner upright 2 causes it to extend or retract relative to the outer upright 1 under the drive of the threaded pair, realizing stepless adjustment of the support frame height and providing precise length control, thereby flexibly adapting to different construction support height requirements.

[0019] More specifically, the inner upright 2 has a sliding groove 5, and a limit block 7 is slidably connected in the sliding groove 5. A connecting rod 6 is fixedly connected to the bottom end of the limit block 7. The connecting rod 6 passes through the bottom end of the inner upright 2 and extends into the outer upright 1. The sliding groove 5, the limit block 7 and the connecting rod 6 in the inner upright 2 together form a guide mechanism. The bottom end of the connecting rod 6 is fixed to the base 18. When the inner upright 2 rotates, the limit block 7 slides up and down in the sliding groove 5 to prevent the inner upright 2 from coming out of the first internal thread groove 3, making the height adjustment operation more stable and controllable.

[0020] More specifically, the bottom end of the outer upright 1 is fixedly connected to a base 18, and the bottom end of the connecting rod 6 is fixedly connected to the top surface of the base 18. A reinforcing rib is provided between the base 18 and the outer upright 1. The base 18 has mounting holes, and the base 18 is fixed to the ground or the underlying structure through the mounting holes, providing a stable bearing base for the entire upright structure. The application of the reinforcing rib significantly enhances the rigidity and bending resistance at the connection between the base 18 and the outer upright 1, effectively distributing the support load to a larger area, greatly improving the overall stability and anti-overturning ability of the upright, and ensuring construction safety.

[0021] More specifically, the rotation adjustment assembly includes a lower connecting block 20, which is located above the inner upright 2. The bottom end of the lower connecting block 20 is fixedly connected to the top end of the inner upright 2. A rotating sleeve 8 is fixedly connected to the top end of the lower connecting block 20. The rotating sleeve 8 has two clearance grooves 10 and a bowl-shaped cavity 9. The rotating sleeve 8 is bowl-shaped, and a first anti-slip pad 11 is fixedly connected to the inner wall of the rotating sleeve 8. The first anti-slip pad 11 is irregularly shaped and its shape is adapted to the bowl-shaped cavity 9. A rotating ball head 12 is provided inside the bowl-shaped cavity 9. The rotating ball head 12 is rotatably connected to the first anti-slip pad 11. The top of the rotating ball head 12 is fixedly connected to the upper connecting block 13. The rotating ball head 12 in the rotating adjustment assembly and the bowl-shaped cavity 9 form a ball joint connection mechanism. The rotating ball head 12 can rotate in multiple directions within the bowl-shaped cavity 9 that wraps the first anti-slip pad 11. The clearance groove 10 provides a small deformation space for the rotating sleeve 8 to adapt to the movement of the ball head, so that the top support 19 can be flexibly adjusted in multiple directions within a certain angle range, thereby accurately fitting the bottom surface of the template and adapting to various complex support angles.

[0022] More specifically, a top support 19 is fixedly connected to the top of the upper connecting block 13. A reinforcing rib is provided between the top support 19 and the upper connecting block 13. The top support 19 has an installation hole. The top support 19 is fixedly connected to the rotating ball head 12 through the upper connecting block 13. As a direct load-bearing surface, the installation hole on the top support 19 facilitates the fixing of timber or template. The reinforcing rib between the top support 19 and the upper connecting block 13 forms a local reinforcement structure, which increases the contact area with the template and significantly improves the structural strength of this key pressure-bearing node, effectively preventing deformation or damage under huge loads.

[0023] More specifically, a rotating sleeve 14 is provided on the inner upright 2. The rotating sleeve 14 has a second internal thread groove 15. The rotating sleeve 14 and the inner upright 2 are threadedly connected to the first internal thread groove 3 through the second internal thread groove 15. A limiting sleeve 16 is fixedly connected to the top of the rotating sleeve 14. The diameter of the limiting sleeve 16 is larger than the diameter of the rotating sleeve 8. The rotating sleeve 14 forms another helical transmission mechanism with the external thread 4 on the inner upright 2 through the second internal thread groove 15 inside it. Rotating the rotating sleeve 14 can drive itself and the limiting sleeve 16 at the top to move axially along the inner upright 2, realizing an indirect, mechanical locking method. The degree of freedom and locking state of the upper rotating adjustment component are controlled by the axial displacement of the limiting sleeve 16.

[0024] More specifically, a second anti-slip pad 17 is fixedly connected to the inner wall of the limiting sleeve 16. The second anti-slip pad 17 is made of rubber. The second anti-slip pad 17 on the inner wall of the limiting sleeve 16 forms a flexible friction locking surface. When the limiting sleeve 16 moves upward under the drive of the rotating sleeve 14, the second anti-slip pad 17 will contact and squeeze the rotating sleeve 8, thereby applying pressure to the rotating ball head 12 in the bowl-shaped cavity 9. The second anti-slip pad 17 made of rubber generates huge friction force, which reliably locks the rotating ball head 12, making it unable to rotate anymore, thereby firmly fixing the adjusted angle and ensuring the stability of the support during construction.

[0025] As can be seen from the above, the specific embodiments of this utility model are as follows: The operator rotates the inner upright 2. Because the inner upright 2 engages with the first internal thread groove 3 inside the outer upright 1 via its external thread 4, and the connecting rod 6 inside the inner upright 2 is limited in distance by the cooperation of the limiting block 7 and the sliding groove 5, the inner upright 2 will not dislodge during rotation, thus smoothly extending or retracting the outer upright 1, achieving adjustment of the total height of the support structure. Once the support height is set, the rotation adjustment assembly located at the top of the inner upright 2 begins to operate. In this assembly, the rotating sleeve 8 fixed to the lower connecting block 20 has a bowl-shaped cavity 9 with a first anti-slip pad 11 embedded within it. The rotating ball head 12 is encased within this cavity and is integrated with the upper connecting block 13 and the top support 19. Utilizing the ball joint principle, the operator can push the top support 19, causing the rotating ball head 12 to rotate in multiple directions within the bowl-shaped cavity 9 under the constraint of the first anti-slip pad 11. The first anti-slip pad 11 provides sufficient frictional damping, allowing the ball head to be temporarily held at any adjusted angle without additional locking, thereby enabling the top support 19 to... To precisely fit the complex tilt angle required by the bottom surface of the template, after the angle adjustment is completed, final locking is required. At this time, the operator rotates the rotating sleeve 14 installed on the inner upright 2. The rotating sleeve 14 engages with the external thread 4 of the inner upright 2 through its internal second internal thread groove 15. Rotating the rotating sleeve 14 will drive it and the limiting sleeve 16 fixed at its top to move upward along the inner upright 2. The inner diameter of the limiting sleeve 16 is larger than the outer diameter of the rotating sleeve 8. It is equipped with a second anti-slip pad 17. When the limiting sleeve 16 moves upward, the second anti-slip pad 17 on its inner wall will contact and wrap around the outer wall of the rotating sleeve 8, continuously applying pressure. This force is transmitted to the bowl-shaped cavity 9 through the rotating sleeve 8, causing the first anti-slip pad 11 to tightly hold the rotating ball head 12. Through this dual action of mechanical compression and rubber friction, the rotating ball head 12 is completely locked and can no longer rotate, thus firmly fixing the angle of the entire top and ensuring the absolute stability of the support under loads such as concrete pouring.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
