Description

Technical Field

[0001] The invention belongs to the technical field of tension beam structures, and in particular relates to a three-way pre-tightened steel wire tension beam structure. Background Art

[0002] In the field of engineering structures, tension beam structure is an important structural form. It introduces tension components such as steel wires and cables into the beam body and uses tension to improve the stress-bearing performance of the beam. It is widely used in many industries such as construction, bridges, and machinery manufacturing.

[0003] At present, in various tension beam structures involving beam structures, it is difficult to balance the load-bearing capacity of the beam and its own weight. On the one hand, in order to meet higher load-bearing requirements, the traditional solution is often to increase the material usage of the beam, which will undoubtedly greatly increase the weight of the beam. On the other hand, if the material usage is reduced simply to reduce the weight of the beam, it will inevitably lead to a decrease in the load-bearing strength of the beam, which cannot meet the load-bearing requirements in the actual processing process.

[0004] Existing technologies have not been able to effectively solve the problem of balancing the strength of the beam and its weight. That is, while increasing the load-bearing strength of the beam, it is difficult to control the weight at the same time, or when reducing the weight, it is impossible to ensure that the beam still has sufficient strength. This situation limits the further development and application of the beam structure in many fields with strict performance requirements.

[0005] In summary, in the existing tension beam structure, there is still a problem in the balance between the bearing capacity of the beam and its own weight. At present, there is an urgent need for a tension beam structure that takes into account both the bearing strength and its own weight. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a three-way pre-tightened steel wire tension beam structure to solve the problem of balancing the bearing capacity of the cross beam and its own weight in the tension beam structure in the prior art.

[0007] One solution of the present invention provides a three-way pre-tightened steel wire tension beam structure, comprising a crossbeam, a steel wire and a pre-tightening assembly, wherein the pre-tightening assembly is mounted on the crossbeam, a steel wire groove is provided on the crossbeam, and the steel wire is mounted in the steel wire groove through the pre-tightening assembly;

[0008] The pre-tightening assembly is used to fix and stretch the steel wire, and the steel wire is used to provide prestressing force for the crossbeam;

[0009] It should be noted that the steel wire is in a stretched state under the tension of the pre-tensioning assembly, and because the steel wire is located in the steel wire groove of the beam, the steel wire can continuously provide prestress for the beam to offset the forces in the directions of the two ends of the beam and the gravity of the beam itself, thereby improving the load-bearing strength of the beam, and the design of the steel wire groove itself reduces the weight of the beam;

[0010] In this solution, by arranging the steel wire in a stretched state in the steel wire groove on the crossbeam, on the one hand, the forces in the directions of the two ends of the crossbeam and its own gravity can be effectively offset, thereby improving the load-bearing strength of the crossbeam. On the other hand, the design of the steel wire groove can effectively reduce the weight of the crossbeam itself, thereby taking into account both the load-bearing strength and the weight of the crossbeam.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The present invention arranges a steel wire in a stretched state in the steel wire groove on the crossbeam. Compared with the traditional crossbeam structure, when the crossbeam bears the same load, the crossbeam has higher load-bearing strength and higher stability, and can adapt to more complex and harsh stress conditions;

[0013] 2. The present invention can reduce the weight of the beam itself by providing a wire groove, and the steel wire and pre-tightening assembly provided in the wire groove further enhance the bearing capacity of the beam, thereby achieving a good balance between the weight and bearing strength of the beam;

[0014] 3. The present invention has a simple structure, high flexibility and strong versatility. The arrangement of the steel wires can be flexibly adjusted according to different engineering requirements and stress characteristics to adjust the tensile state of the steel wires and further adjust the prestress of the steel wires on the beams. In addition, the present invention can also be combined and expanded with other structures or components to meet more complex processing requirements.

[0015] In one of the schemes, the pre-tightening assembly includes a fixing screw, which passes through the cross beam and is installed on the cross beam, and the end of the steel wire is fixed in the steel wire groove by the fixing screw.

[0016] In this solution, the ends of the steel wires are fixed in the steel wire grooves by fixing screws, so that the steel wires can be placed in a stretched state to provide an upward prestress to the crossbeam, thereby increasing the load-bearing strength of the crossbeam.

[0017] In one of the solutions, at least two fixing screws are provided, and the two fixing screws respectively fix the two ends of the steel wire on the crossbeam.

[0018] In this solution, the two ends of the steel wire are fixed to the crossbeam by at least two fixing screws respectively, which can ensure the stability of the steel wire when the crossbeam bears load, so that it can stably provide prestress for the crossbeam to enhance the stability of the crossbeam.

[0019] In one of the solutions, the pre-tightening assembly further includes a tightening screw, which is screwed into the wire groove and lifts up the wire.

[0020] In this solution, the steel wire is lifted up by screwing the tightening screw into the wire groove. On the basis of fixing the two ends of the steel wire on the beam by the fixing screws, the steel wire can be lifted up from the wire groove to further stretch the steel wire and provide prestress in the direction of the two ends of the beam to the beam. At the same time, the prestress strength provided by the steel wire to the beam is further improved to enhance the load-bearing strength of the beam.

[0021] In one of the solutions, at least two of the tightening screws are provided, and the two tightening screws are respectively located on the inner sides of the two fixing screws.

[0022] In this solution, the steel wires located inside the two fixing screws are lifted up respectively by at least two tightening screws. The tightening position of the tightening screws can be freely selected according to user needs to control the position of the prestress provided by the steel wire to the beam, and enhance the prestress strength provided by the steel wire to the beam to enhance the load-bearing strength of the beam.

[0023] In one of the solutions, the pre-tightening assembly further includes a support block, which is installed in the crossbeam and pushes the steel wire downward.

[0024] In this solution, by installing the support block in the crossbeam and pushing the steel wire downward, the tension of the steel wire can be increased, thereby enhancing the prestressed strength provided by the steel wire to the crossbeam, thereby enhancing the load-bearing strength of the crossbeam.

[0025] In one embodiment, the support block is located in the middle of the beam.

[0026] In this solution, by setting the support block in the middle of the beam, the steel wire can be pushed downward in the middle of the beam, and then the two aforementioned tightening screws are respectively installed on both sides of the position where the steel wire is pushed out by the support block, so that the prestress of the entire beam is balanced, thereby ensuring the stability of the beam during the processing.

[0027] In one of the solutions, the fixing screw includes a through screw rod and a fixing nut. The fixing screw passes through the cross beam through the through screw rod, and the fixing screw fixes the steel wire to the cross beam through the fixing nut.

[0028] In this solution, the screw rod passes through the crossbeam and the steel wire is firmly fixed to the crossbeam by a fixing nut, thereby ensuring a stable connection between the steel wire and the crossbeam. When the crossbeam is subjected to various external forces, the steel wire will not be easily displaced or loosened, thereby ensuring the stability of the entire tension beam structure and the effective use of the steel wire prestress when the tension beam structure is working.

[0029] In one of the solutions, the tightening screw includes a tightening screw rod, and the tightening screw is screwed into the wire groove through the tightening screw rod to lift up the wire.

[0030] In this solution, the tension of the steel wire can be accurately adjusted by screwing the tightening screw into the wire groove and lifting the steel wire. The operator can adjust the prestress provided by the steel wire to the beam by rotating the tightening screw according to different engineering requirements and the load borne by the beam to meet the use requirements under various complex working conditions.

[0031] In one of the solutions, the wire groove is arranged on the side of the crossbeam, and a mounting screw hole is provided at the bottom of the crossbeam, and the mounting screw hole is used to install the preload assembly.

[0032] In this solution, by providing mounting screw holes that can cooperate with the fixing screws and the tightening screws in the pre-tightening assembly, the steel wires in the wire grooves are fixed and stretched, so as to further enhance the stability of the entire tension beam structure.

[0065] The specific structure and working principle of one preferred embodiment are described below:
