Technical Field

[0001] This utility model belongs to the field of formwork construction technology, and in particular relates to a universal connection component for curved building formwork. Background Technology

[0002] In construction engineering, when building large public buildings with streamlined appearances, such as stadiums and opera houses, curved building formwork is needed to ensure that the concrete is poured into a curved shape that meets the design requirements. It provides precise forming boundaries for the concrete, ensuring that the building's appearance achieves the smooth curves and unique shape desired in the design.

[0003] In the formwork erection stage of building construction, the connection nodes between curved building formwork can only achieve fixed-angle connections, which cannot meet the different angle connection requirements caused by the complex and diverse shapes of curved building formwork. In actual construction, a lot of time and effort is often required to adjust the connection structure to adapt to the curved surface, and the tightening effect after connection is not good, and the firmness of the connection is limited. In subsequent use, when subjected to external forces, the curved building formwork is prone to loosening and deformation, affecting the stability and safety of the overall structure. Therefore, it is necessary to provide a universal connection component for curved building formwork, which uses universal ball joints as connection nodes, so that the connection angle can be adjusted according to the use and erection requirements during the assembly process.

An arc-shaped groove adapted to the first bolt is opened on the front side of the ball head seat.

[0006] Preferably, the top and bottom of the front side of the ball head are threaded with a second bolt, and the rear end of the second bolt penetrates into the interior of the curved building template and is threadedly connected thereto.

[0022] In the following description, embodiments of the universal connection assembly for curved building formwork of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a universal connection assembly for curved building formwork according to an embodiment of the present invention. It includes a horizontal support rod 2 located on the outer side between two curved building formworks 1. Both ends of the horizontal support rod 2 are rotatably connected to side tie rods 3. A connection assembly 4 is provided at the end of the side tie rod 3 away from the horizontal support rod 2. The connection assembly 4 includes a first bolt 41 extending from the front to the rear of the side tie rod 3. Nuts 42 are threaded onto both the front and rear sides of the first bolt 41, tightly fitting against the surface of the side tie rod 3. A universal ball joint 43 is fixedly connected to the rear end of the first bolt 41. A ball joint seat 44 is provided on the front side of the curved building formwork 1. An arc-shaped groove 45 adapted to the first bolt 41 is opened on the front side of the ball joint seat 44. Second bolts 46 are threaded onto the top and bottom of the front side of the ball joint seat 44. The rear end of the second bolt 46 extends into the interior of the curved building formwork 1 and is threaded thereto. The second bolt 46 allows the ball joint seat 44 to be installed on the surface of the curved building formwork 1, facilitating the use of the two curved surfaces. The building template 1 is connected, and due to the universal rotation connection characteristics of the universal ball joint 43 and the ball joint seat 44, the ball joint seat 44 can be installed in a designated position as required by the second bolt 46. A tie assembly 5 is provided on the rear side of the cross brace 2. The tie assembly 5 includes a threaded rod 51 that is threaded to the cross brace 2. The rear end of the threaded rod 51 is rotatably connected to the extrusion plate 53 through the bearing. A rubber pad 54 is fixedly connected to the inner cavity of the extrusion plate 53. The rear side of the rubber pad 54 is pressed against the surface of the two curved building templates 1. The front end of the threaded rod 51 extends to the front side of the cross brace 2 and is fixedly connected to the operating handle 52. Through the setting of the tie assembly 5, the threaded rod 51 and the operating handle 52 work together to push the extrusion plate 53, extruding the connection position of the two curved building templates 1. At the same time, under the reaction force, the two side tie rods 3 are pulled and tightened, making the connection of the two curved building templates 1 more secure. An elastic steel strip 6 is engaged inside the curved building template 1.

[0024] Working principle: When using this utility model, the user engages the elastic steel strip 6 within the inner cavity of the curved building template 1 and assembles the curved building template 1. Then, the user fixes the ball head seat 44 onto the surface of the curved building template 1 using the second bolt 46. Next, the user engages the universal ball head 43 within the inner cavity of the ball head seat 44, so that the first bolt 41 is located within the inner cavity of the arc-shaped groove 45. Then, the user rotates the threaded rod 51 using the operating handle 52. During rotation, the threaded rod 51, through the engagement of its surface threads and the threads of the cross brace 2, pushes the extrusion plate 53 backward. The user adjusts the extrusion plate... The position of the pressure plate 53 ensures that it can simultaneously press against the surfaces of the two curved building templates 1. Then, the threaded rod 51 is continuously rotated, causing the rubber pad 54 to press against the surface of the curved building template 1. Due to the obstruction of the curved building template 1, the threaded rod 51 generates a reverse force on the cross brace 2, causing the cross brace 2 to move forward and simultaneously pull on the two side tie rods 3, so that the two curved building templates 1 can be pulled against each other. During the assembly process, the universal ball joint 43 can rotate freely in the inner cavity of the ball joint seat 44, so that the cross brace 2 and the side tie rods 3 can be tilted to form a connection, thereby meeting the fastening requirements of different connection positions in turn.

[0025] In summary, this universal connection assembly for curved building formwork, through the combined use of the horizontal brace 2, the side tie rod 3, and the connection assembly 4, enables a universal connection between two adjacent curved building formworks 1. At the same time, with the combined use of the horizontal brace 2 and the tie assembly 5, the two curved building formworks 1 are pulled and tightened, thus achieving the purpose of universally adjustable connection angle and reliable pull-tightening.
