Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and more specifically, it relates to a clamp-type adjustable truss structure. Background Technology

[0002] During bridge construction, after the supporting columns are erected, a connecting system is typically installed between the steel pipe columns to enhance structural stability. However, in existing technologies, the traditional connecting system between steel pipe columns is welded. The system is welded as a whole on the ground and then hoisted to the steel pipe columns for welding. This results in significant risks associated with high-altitude welding operations after hoisting. Furthermore, dismantling the connecting system requires cutting it off, causing considerable damage and making it inconvenient to reuse. Additionally, because the distances between steel pipe columns vary, different sizes of connecting systems need to be designed, leading to the need for multiple sets of connecting systems and resulting in design waste. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a clamp-type adjustable truss structure to solve the technical problem in the prior art where the truss as a whole is connected to the column by welding, which requires cutting during dismantling, causing great damage and making it inconvenient to reverse.

[0004] The purpose and function of this utility model's clamp-type adjustable truss structure are achieved through the following specific technical means:

[0005] An adjustable truss structure with clamps includes multiple sets of truss structures and multiple sets of clamp assemblies, with one set of truss structures located between two adjacent sets of clamp assemblies; each clamp assembly has a first connecting plate at both ends, and each truss structure has a second connecting plate at both ends; the first connecting plate and the second connecting plate are detachably connected to connect the truss structure between two clamp assemblies; each clamp assembly includes two sets of semi-circular clamps, and a column connection space is formed between the two sets of semi-circular clamps.

[0007] According to a preferred embodiment, the outer ring surface of the semi-circular ring clamp is provided with a support rod parallel to the line connecting the two columns; the first connecting plate is provided on the support rod, and its end face is perpendicular to the support rod.

[0008] According to a preferred embodiment, the truss structure includes multiple sets of connecting units. Each connecting unit includes a diagonal bar, two sets of vertical bars, and two sets of horizontal bars. The two sets of horizontal bars are spaced apart vertically. The two sets of vertical bars are located between the two sets of horizontal bars and are connected to the two horizontal bars at their respective ends. The vertical bars and the horizontal bars are perpendicular to each other. The two ends of the diagonal bar are connected to the two sets of horizontal bars.

[0009] According to a preferred embodiment, the second connecting plate is disposed at both ends of the crossbar, and the second connecting plate near the clamp assembly is detachably connected to the first connecting plate by bolts.

[0010] According to a preferred embodiment, an extended crossbar is provided between two adjacent sets of the connecting system units; the extended crossbar is provided with a third connecting plate at both ends.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 5As shown, this utility model provides a clamp-type adjustable truss structure, including multiple sets of truss structures and multiple sets of clamp components. A truss structure is provided between two adjacent sets of clamp components. The alternating arrangement of multiple sets of clamp components and truss structures allows the device to form a stable spatial structure, providing reliable support for bridges and other structures, and improving the structural stability of the device. Each clamp component has a first connecting plate 13 at both ends, and each truss structure has a second connecting plate 14 at both ends. The arrangement of the first connecting plate 13 and the second connecting plate 14 at both ends of the clamp components and truss structures provides an interface for connection between the two, improving the ease of connection. The first connecting plate 13 and the second connecting plate 14 are detachably connected to connect the truss structure between the two clamp components. This detachable connection method allows for easy assembly and disassembly of the device, improving its reusability. Each clamp component includes two sets of semi-circular clamps 11, with a column connection space formed between the two sets of semi-circular clamps 11. By setting two sets of semi-circular ring clamps 11 to form a column connection space, the device can adapt to columns of different sizes, making it easy to install on the columns and improving the adaptability of the device.

[0025] like Figure 1 , 2 As shown, the end faces of the semicircular ring clamps 11 are provided with clamp fixing plates 12 that are flush with the end faces; two sets of semicircular ring clamps 11 are arranged opposite each other, and the two sets of opposite clamp fixing plates 12 are detachably connected by bolts. By setting clamp fixing plates 12 and using bolts for detachable connection, the device can easily fix the two semicircular ring clamps 11 together, improving the ease of installation and the firmness of fixation of the device.

[0026] The outer ring of the semi-circular clamp 11 is provided with a support rod 18 parallel to the line connecting the two columns; the first connecting plate 13 is provided on the support rod 18, and its end face is perpendicular to the support rod 18. By setting the support rod 18 and installing the first connecting plate 13 on the outer ring of the clamp, the position and angle of the first connecting plate 13 can be optimized, and the connection with the truss structure can be better improved, thus enhancing the connection rationality and stability of the device.

[0027] like Figure 2 , 3 As shown, the truss structure includes multiple sets of connecting units. Each connecting unit includes a diagonal member 15, two sets of vertical members 16, and two sets of horizontal members 17. The two sets of horizontal members 17 are spaced apart vertically. The two sets of vertical members 16 are located between the two sets of horizontal members 17 and are connected to the two horizontal members 17 at both ends, with the vertical members 16 and horizontal members 17 being perpendicular to each other. The two ends of the diagonal member 15 are connected to the two sets of horizontal members 17. By adopting this connecting unit structure, the device can enhance the strength and stability of the truss structure itself, thereby improving the structural strength of the device.

[0028] like Figures 2 to 5 As shown, the second connecting plate 14 is located at both ends of the crossbar 17. The second connecting plate 14, which is close to the clamp assembly, is detachably connected to the first connecting plate 13 by bolts. By setting the second connecting plate 14 at both ends of the crossbar 17 and bolting it to the first connecting plate 13, the device can achieve a reliable connection between the truss structure and the clamp assembly, thus improving the connection reliability of the device.

[0029] An extended crossbar 19 is provided between two adjacent sets of connecting units; a third connecting plate 20 is provided at both ends of the extended crossbar 19. By setting the extended crossbar 19 and the third connecting plates 20 at both ends, the length of the truss structure can be adjusted according to actual needs, thus improving the length adjustability of the device.

[0030] A set of third connecting plates 20 near the clamp assembly is detachably connected to the first connecting plate 13 by bolts, while another set of third connecting plates 20 away from the clamp assembly is detachably connected to the second connecting plate 14 at the end of the truss structure by bolts. This detachable bolt connection method allows for easier adjustment of the connection between the truss structure and the clamp assembly, as well as the overall length of the device, thus improving its installation flexibility and adjustability.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In use, place two sets of semi-circular ring clamps 11 around the column, aligning and fitting the clamp fixing plates 12 to form a column connection space. Adjust the clamp spacing according to the column size to ensure the clamps wrap around the column. Secure the two semi-circular ring clamps 11 by bolts or detachable ring buckles through the holes in the clamp fixing plates 12. The semi-circular ring clamps 11 can accommodate columns of different diameters and shapes, such as round and square, without the need for custom processing. Bolt or ring buckle connections require no welding, resulting in high construction efficiency. The connecting unit consists of diagonal bars 15, vertical bars 16, and horizontal bars 17, forming a stable frame structure. Adjacent connecting units are fitted together by the second connecting plate 14 and locked with bolts to form the truss body. Truss length adjustment: 1. Add an extended horizontal bar 19 between adjacent connecting units, with its two ends' third connecting plates 20 detachably connected to the second connecting plates 14 of the connecting units on both sides by bolts. 2. Adjust the overall truss length directly by adjusting the number of connecting units or replacing horizontal bars 17 with different lengths. The second connecting plates 14 at both ends of the truss are bolted to the first connecting plate 13 of the clamp assembly. The bolts have inner and outer nuts for fine-tuning the spacing and securing the truss. Adjusting the relative position of the truss and clamp by rotating the adjusting nuts, and then tightening them after eliminating installation deviations, enhances the truss's wind and earthquake resistance through the intersection of diagonal braces 15 and vertical braces 16. Horizontal braces 17 provide horizontal support, improving overall stability. By lengthening horizontal braces 19 or adding / removing units, different column spacings can be accommodated without redesigning the overall structure. Bolted connections ensure a secure connection between the truss and clamp assembly, preventing loosening and making it suitable for high-load scenarios. All connections use bolts, studs, or rings, allowing for assembly and disassembly without specialized tools. After disassembly, all components can be preserved intact for use in other projects or temporary structures.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
