Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to the optimization of the angle adjustment of the top support. Background Technology

[0002] In building construction, the formwork support work for pitched roofs and irregularly shaped roofs faces challenges. Conventional adjustable top supports can only achieve vertical height adjustment, which is difficult to adapt to the tilt angle requirements of pitched roofs. This results in poor fit between the formwork and the top support surface, and problems such as formwork deformation and insufficient flatness of the roof after pouring are prone to occur.

[0003] Chinese patent document CN115653292A discloses an angle-adjustable top support structure and its usage method. In this technical solution, the top support structure slides along the arc-shaped top surface of the base to change the angle between the top support and the rod, thereby allowing the top support to fit against the template. That is, the inclination of the top support matches that of the template, solving the problem that the top support cannot be used on inclined templates. By adjusting the angle of the top support, it can be adapted to the template, thereby improving the support effect on the template, ensuring the overall stability of the template, and improving the construction quality.

[0004] However, the above solution has the following drawbacks: First, the top support can only slide along the pre-set arc-shaped top surface of the base, and the adjustment range is limited to a single arc trajectory, which cannot cope with complex scenarios such as sloping roofs and irregular structures that require multi-directional angle adjustment. Second, the screw height adjustment and angle adjustment are linked, and adjusting the angle may affect the elevation of the top support, requiring repeated calibration, making it difficult to simultaneously meet the complex requirements of different heights and slopes. Utility Model Content

[0005] To overcome the shortcomings of the prior art, an adjustable-angle top support is provided.

[0006] This utility model is achieved through the following technical solution: an adjustable-angle top support, including a support screw and a support plate; further comprising: a spherical rotating mechanism, assembled between the support screw and the support plate; a locking bolt for fixing the rotation angle of the spherical rotating mechanism; the spherical rotating mechanism includes: a rotating ball, the top of which is connected to the support plate; a ball seat, the bottom of which is connected to the support screw; the ball seat has a spherical cavity adapted to the outer surface of the rotating ball; the locking bolt passes through a bolt hole provided on the side wall of the ball seat and abuts against the rotating ball.

[0007] The aforementioned device replaces the traditional arc-shaped sliding structure with a spherical rotating mechanism. The rotating ball can rotate in three-dimensional space in multiple directions within the spherical cavity of the ball seat, expanding the adjustment range of the tray angle from a single arc trajectory to free adjustment in all directions, perfectly adapting to the adjustment needs of complex scenarios such as pitched roofs and irregular structures. Specifically, the support screw and the tray are connected by an independent spherical rotating mechanism, with the height adjustment of the support screw and the angle adjustment of the rotating ball being two independent operations; these two operations do not interfere with each other, avoiding the repeated calibration problems caused by traditional linked designs, and simultaneously meeting the complex requirements of different heights and slopes.

[0008] In a preferred embodiment of this utility model, multiple bolt holes are provided, evenly distributed on the side wall of the ball seat, and connected to the spherical cavity.

[0009] In a preferred embodiment of this utility model, a connecting rod is fixedly connected between the rotating ball and the bottom of the support plate.

[0010] In a preferred embodiment of this utility model, the central axis of the ball seat is the same as the central axis of the screw.

[0011] In a preferred embodiment of this utility model, an adjusting nut is screwed onto the supporting screw, and the lower end face of the adjusting nut abuts against the upper part of the steel pipe of the scaffold; the supporting screw is sleeved inside the steel pipe, and the height of the top support is adjusted by rotating the adjusting nut to drive the supporting screw to move axially.

[0012] In a preferred embodiment of this utility model, the ball seat and the support screw are connected by threads. The bottom of the ball seat is provided with an internal thread connection part, and the top of the support screw is provided with an external thread connection part that matches the internal thread connection part.

[0013] In a preferred embodiment of this utility model, the locking bolt is provided with an anti-slip reinforcement structure at one end near the rotating ball; the anti-slip reinforcement structure includes: an arc-shaped contact surface, the radius of curvature of which matches the curvature of the rotating ball surface; and anti-slip textures, which are radially distributed on the arc-shaped contact surface.

[0014] In a preferred embodiment of this utility model, an elastic buffer layer is embedded in the gaps of the anti-slip texture.

[0015] In a preferred embodiment of this utility model, the ball seat and the supporting screw are integrally formed.

[0016] In a preferred embodiment of this utility model, the tray is shaped like a U-shaped groove; the bearing surface of the U-shaped groove is provided with anti-slip texture.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] An adjustable-angle top support is provided, which enables the support plate to rotate freely in multiple directions in three-dimensional space through a spherical rotation mechanism, breaking through the limitations of traditional arc trajectory and adapting to the angle adjustment needs of complex scenarios such as sloping roofs and irregular structures; the locking bolts fix the angle by abutting against the surface of the sphere, ensuring construction safety.

[0019] Furthermore, the even distribution of multiple bolt holes enhances locking reliability and avoids the risk of stress concentration or loosening caused by single-point locking.

[0020] Furthermore, the connecting rod strengthens the rigid connection between the support plate and the rotating ball, preventing the support plate from becoming disengaged or shifting during adjustment.

[0021] Furthermore, the coaxial design of the ball seat and the support screw ensures uniform force distribution during height adjustment, avoiding structural deformation caused by off-center loading.

[0022] Furthermore, the adjusting nut allows for independent height adjustment, which does not interfere with angle adjustment and reduces calibration steps.

[0023] Furthermore, the threaded connection facilitates quick assembly and disassembly of the ball seat and the support screw, adapting to the modular requirements of different scenarios.

[0024] Furthermore, the anti-slip reinforcement structure increases the friction between the locking bolt and the rotating ball, preventing loosening after angle adjustment.

[0025] Furthermore, the elastic buffer layer absorbs vibrations and disperses pressure, extending the service life of the locking structure.

[0026] Furthermore, the one-piece molding structure eliminates connection gaps, improving the connection strength and overall integrity between the ball seat and the support screw. It also avoids the problem of easily lost parts.

[0027] Furthermore, the U-shaped groove structure uses side wall limiting and locking to connect the template support frame, and the anti-slip texture increases the friction coefficient of the contact surface; the two work together to effectively resist horizontal shear force, prevent the steel pipe from coming out or shifting, prevent the supporting steel pipe from sliding, and improve the connection stability between the top support and the steel pipe.

[0028] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0036] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0037] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to facilitate the description of the embodiments and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] like Figures 1 to 4 As shown in Embodiment 1: This embodiment provides an adjustable-angle top support, including a support screw 1, a support plate 2, a spherical rotating mechanism 3, and a locking bolt 4.

[0039] The spherical rotation mechanism 3 is assembled between the support screw 1 and the support plate 2, and consists of a rotating ball 31 and a ball seat 32. The top of the rotating ball 31 is rigidly connected to the support plate 2 via a connecting rod 311, ensuring synchronous movement between the two. The connecting rod 311, as a rigid force transmission component, effectively prevents angle adjustment failure caused by deformation or loosening of the support plate 2. The ball seat 32 has a spherical cavity 321, which forms a ball hinge structure with the rotating ball 31, ensuring that the rotating ball 31 can rotate in any direction within the spherical cavity 321 with the center of the ball as the fulcrum. This breaks through the limitations of traditional arc-shaped trajectories, thus adapting to the three-dimensional angle adjustment needs of complex scenarios such as sloping roofs and irregular structures.

[0040] Multiple bolt holes 322 are evenly distributed on the sidewall of the ball seat 32, through which locking bolts 4 pass and abut against the rotating ball 31. Multiple locking bolts 4 apply uniform pressure from different directions, dispersing the locking force and avoiding stress concentration or loosening at a single point, thus significantly improving structural stability. In this embodiment, four locking bolts 4 are preferably arranged in a cross-shaped, symmetrical distribution.

[0041] An adjusting nut 5 is screwed onto the support screw 1. Rotating the adjusting nut 5 drives the support screw 1 to move axially within the scaffold steel pipe. This height adjustment relies solely on the threaded transmission between the screw and the steel pipe, without altering the relative position of the ball joint mechanism. The ball seat 32 and the support screw 1 are integrally formed (e.g., manufactured through casting or forging), eliminating connection gaps and improving the connection strength and overall integrity of the top support under heavy loads. Simultaneously, the ball seat 32 and the support screw 1 are coaxially designed, ensuring that the axial movement of the screw coincides with the rotation center of the ball, reducing eccentric bending moments and ensuring uniform force distribution during height adjustment.

[0042] The pallet 2 is designed with a U-shaped groove structure. Its U-shaped contour can effectively fit the outer surface of components such as steel pipes and I-beams, reducing lateral displacement. The inner surface of the U-shaped groove (including the bottom and side walls) is provided with anti-slip texture, which increases the static friction between the pallet and the components by increasing the surface roughness.

[0043] Example 2: Based on the structure of Example 1, this example adjusts the connection method between the ball seat 32 and the support screw 1: the ball seat 32 has an internal threaded connection part at its bottom, and the support screw 1 has a matching external threaded connection part at its top. The two are detachably connected by threads. This threaded connection method provides convenient assembly and disassembly functions, making it easy to replace ball seats of different specifications according to load or environmental requirements (such as differences in load-bearing capacity and rotation range), thereby improving the modular versatility of the top support.

[0044] Example 3: Based on the structure of Example 1 or 2, this example optimizes the structure of the locking bolt 4 near the rotating ball 31 by adding an anti-slip reinforcement structure: the radius of curvature of the arc-shaped contact surface 41 matches the surface of the rotating ball 31 to increase the contact area; anti-slip textures 42 are distributed on the arc-shaped contact surface 41, which enhance friction through mechanical interlocking and prevent the ball from sliding; an elastic buffer layer is embedded in the groove of the anti-slip texture 42, filling the gap and providing elastic deformation space, which can effectively absorb vibration energy, disperse local pressure, reduce fatigue damage, and extend the service life of the locking structure.

[0045] Instructions for using and constructing an adjustable-angle top support:

[0046] Step 1: Initial Installation and Angle Adjustment. Install the support screw 1 inside the steel pipe of the scaffold. Screw the adjusting nut 5 onto the support screw 1, with its lower end abutting against the top of the steel pipe. When the scaffold steel pipe is fixed, rotate the adjusting nut 5 to drive the support screw to move axially, thus initially adjusting the height of the top support. Loosen all locking bolts 4, and freely adjust the angle of the support plate 2 using the ball joint mechanism 3, ensuring it fits tightly against the bottom surface of the pitched roof or irregularly shaped formwork.

[0047] Step 2: Angle Locking and Height Fine-tuning. After the angle of the support plate 2 is adjusted to the correct position, symmetrically tighten the multiple locking bolts 4 distributed on the side wall of the ball seat 32, so that its arc-shaped abutment surface 41 firmly presses against the outer side wall of the rotating ball 31, thus reliably fixing the angle. If a height fine-tuning is required, simply rotate the adjusting nut 5; this operation does not affect the locked angle.

[0048] Step 3: Dismantling and Maintenance. After construction is completed, dismantle the top support in reverse order. Clean the concrete or debris adhering to the surfaces of all components (such as support plate 2, rotating ball 31, locking bolt 4, support screw 1, etc.). Pay special attention to checking the wear of the spherical rotating mechanism 3, and perform necessary maintenance or replacement on vulnerable parts such as the anti-slip structure of the rotating ball 31 and locking bolt 4, and the threads of the support screw 1 to ensure that the top support can be reused.

[0049] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
