Abstract

This utility model relates to the field of structural building technology, and specifically provides a highly efficient wind-resistant tensioned beam structure. This structure consists of a truss arch structure, a prestressed cable structure, and a strut structure. The prestressed cable structures are respectively positioned on both sides of the wind pressure zone on the lower surface of the truss arch structure, while the strut structure connects the truss arch structure and the prestressed cable structure, forming a synergistic system that combines rigidity and flexibility. The cable and strut system provides elastic support for the main truss arch, making the bending moment and distribution of the main truss arch more uniform under wind loads. This significantly reduces the stress on key components, greatly reduces structural deformation, and improves overall stiffness, ultimately achieving efficient and stable operation of the structure in strong wind environments and comprehensively improving wind resistance performance.

Description

Technical Field

[0001] This utility model relates to the field of structural building technology, and in particular provides a high-efficiency wind-resistant tensioned beam structure. Background Technology

[0002] In traditional large-span storage yard enclosure projects, reticulated shell structures and space truss structures dominate. Faced with wind loads, these structures rely solely on the mechanical properties of the steel structure itself to withstand external loads. To effectively address the displacement and deformation caused by wind loads, the structure needs not only excellent stiffness but also strong load-bearing capacity. Constructing large-span storage yards in high-wind-pressure areas presents a formidable challenge for traditional structural systems. In such special environments, the amount of steel used in traditional reticulated shell or space truss structures will increase significantly, leading to a substantial rise in construction costs. Utility Model Content

[0003] Addressing the technical bottlenecks of insufficient wind-resistant stiffness and stress concentration in traditional large-span enclosed storage yard structures under wind loads, this invention provides a highly efficient wind-resistant tensioned beam structure. This structure innovatively integrates the truss arch bending member, the prestressed cable tension member, and the struts connecting them into a rigid-flexible structural system. Notably, the tensioned beam structure is precisely positioned within the wind pressure zone, with the cable and strut system providing elastic support for the main truss arch. Under wind loads, this synergistic system effectively adjusts the magnitude and distribution of the bending moment of the main truss arch, resulting in more uniform stress distribution; simultaneously, it significantly reduces structural deformation and substantially improves overall stiffness, ultimately achieving highly efficient optimization of wind resistance performance and providing a novel solution for the wind-resistant design of large-span enclosed storage yard structures.

[0004] This utility model is implemented as follows: it provides a high-efficiency wind-resistant tensioned beam structure, including a truss arch structure, a prestressed cable structure and a strut structure. A prestressed cable structure is set at the wind pressure zone on both sides of the lower surface of the truss arch structure, and a strut structure is connected between the truss arch structure and the prestressed cable structure.

[0005] Preferably, the prestressed cable structure includes a steel cable, an adjusting cable head, and a fixed cable head. The adjusting cable head and the fixed cable head are respectively connected to both ends of the steel cable. End lugs are provided at the connection points between the truss arch structure and the prestressed cable structure. The adjusting cable head and the fixed cable head are connected to the end lugs by pins.

[0006] In a further preferred embodiment, the adjusting cable head includes an adjustable cable head, a screw, and an adjustable anchor cup. The two ends of the screw are respectively threaded into the adjustable anchor cup and the adjustable cable head. The other end of the adjustable anchor cup is fixedly connected to the steel cable, and the other end of the adjustable cable head is connected to the end ear plate via a pin.

[0007] Preferably, the strut structure includes a strut, a head plate, and a connecting plate. Head plates are provided at both ends of the strut, and connecting plates are provided on the head plates. The connecting plates are provided with connecting holes. An intermediate ear plate is provided at the position where the truss arch structure connects to the strut structure, and an intermediate cable clamp is provided at the position where the prestressed cable structure connects to the strut structure. The connecting plate is connected to the intermediate ear plate and the intermediate cable clamp by a pin.

[0008] Preferably, the truss arch structure includes an upper chord, a lower chord, straight web members, and diagonal web members. The straight web members and diagonal web members are connected between the upper chord and the lower chord. Between two straight web members, several diagonal web members are connected end to end.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] This invention provides a highly efficient wind-resistant tensioned beam structure that precisely addresses the load challenges in wind pressure zones. The structure, through its main truss arch, prestressed cables, and connecting struts, constructs a synergistic force-bearing system that combines rigidity and flexibility, forming a highly efficient solution for resisting wind loads.

[0011] In this system, the main truss arch, as a rigid core component, bears the main load of wind pressure thanks to its high-strength structural design and reasonable mechanical layout, providing stable support for the overall structure. The prestressed cables, through precise prestressing technology, construct a reverse tension system, forming a bidirectional force balance with the main truss arch. When the two work together, the cable and strut system provides elastic support to the main truss arch, making the bending moment and distribution of the main truss arch more uniform under wind loads. This significantly reduces the stress on key components, greatly reduces structural deformation, and improves overall stiffness, ultimately achieving efficient and stable operation of the structure in strong wind environments and comprehensively enhancing wind resistance performance.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] refer to Figures 1-5 This utility model provides a high-efficiency wind-resistant tensioned beam structure, including a truss arch structure 1, a prestressed cable structure 2, and a strut structure 3. A prestressed cable structure 2 is respectively installed on both sides of the lower surface of the truss arch structure 1 at the wind pressure zone positions. A strut structure 3 connects the truss arch structure 1 and the prestressed cable structure 2. The prestressed cable structure 2 and the strut structure 3, together with the truss arch structure 1, jointly resist wind loads. For example... Figure 1 As shown, when the wind comes from Figure 1 The wind blows from the left towards the truss arch structure 1, and the truss arch structure 1, together with the prestressed cable structure 2 and strut structure 3 on the left, resist the wind load.

[0020] When the tensioned beam structure provided by this utility model encounters strong winds, the truss arch structure 1, being a rigid member, primarily bears bending moments and is the main load-bearing component of the structure. The prestressed cable structure 2 primarily bears tensile forces. By applying prestress to the prestressed cable structure 2, forces opposite to the external loads are generated within the structure, thereby reducing the internal forces and deformation of the tensioned beam and improving the overall load-bearing capacity and stiffness of the structure. The strut structure 3 transfers the tensile force of the prestressed cable structure 2 to the truss arch structure 1, enabling the truss arch structure 1 and the prestressed cable structure 2 to work together.

[0021] As a specific implementation of the prestressed cable structure 2, the prestressed cable structure 2 includes a steel cable 21, an adjusting cable head 22, and a fixed cable head 23.

End ear plates 15 are provided at the connection positions of the truss arch structure 1 and the prestressed cable structure 2. The adjusting cable head 22 and the fixed cable head 23 are connected to the end ear plates 15 by pins.

[0022] The length of the prestressed cable structure 2 is adjusted by adjusting the cable head 22, thereby adjusting the force between the prestressed cable structure 2 and the truss arch structure 1.

[0023] Preferably, the adjusting cable head 22 includes an adjustable cable head 221, a screw 222, and an adjustable anchor cup 223. The two ends of the screw 222 are respectively threaded into the adjustable anchor cup 223 and the adjustable cable head 221. The other end of the adjustable anchor cup 223 is fixedly connected to the steel cable 21, and the other end of the adjustable cable head 221 is connected to the end ear plate 15 through a pin.

[0024] When it is necessary to adjust the length of the prestressed cable structure 2, rotate the screw 222. The screw 222 screws into or out of the adjustable anchor cup 223. The screw 222 drives the adjustable cable head 221 to rotate, thereby adjusting the overall length of the prestressed cable structure 2.

[0025] As a specific implementation of the strut structure 3, the strut structure 3 includes a strut 31, a head plate 32, and a connecting plate 33. The head plates 32 are respectively provided at both ends of the strut 31, and the connecting plates 33 are respectively provided on the head plates 32. The connecting plates 33 are provided with connecting holes. An intermediate ear plate 16 is provided at the position where the truss arch structure 1 connects to the strut structure 3, and an intermediate cable clamp 24 is provided at the position where the prestressed cable structure 2 connects to the strut structure 3. The connecting plate 33 is connected to the intermediate ear plate 16 and the intermediate cable clamp 24 by a pin.

[0026] As a specific implementation of the truss arch structure 1, the truss arch structure 1 includes an upper chord 11, a lower chord 12, straight web members 13, and diagonal web members 14. The straight web members 13 and diagonal web members 14 are connected between the upper chord 11 and the lower chord 12. Between two straight web members 13, several diagonal web members 14 are connected end-to-end. The upper chord 11, lower chord 12, straight web members 13, and diagonal web members 14 are all square or rectangular tubes.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
