Description

Technical Field

[0001] The utility model relates to the technical field of building steel beams, in particular to a telescopic steel beam which is convenient for construction. Background Art

[0002] Steel beams are important components in construction and engineering projects, and are widely used in bridges, buildings, and various industrial facilities. In order to adapt to the needs of different construction sites, the design of steel beams needs to be flexible and able to be adjusted according to specific conditions. In the actual construction process, traditional fixed-size steel beams often need to be cut and adjusted on-site when encountering structural requirements of different sizes and shapes, which not only increases the construction process and labor intensity, but may also lead to material waste and project progress delays. Therefore, telescopic steel beams that are easy to adjust and construct came into being to improve construction efficiency and material utilization.

[0003] However, in the prior art, traditional steel beams have some shortcomings in terms of construction adaptability. First, fixed-size steel beams are difficult to flexibly adjust when facing different construction sites and structural requirements, and need to be adapted by cutting or splicing, which increases the complexity and workload of construction. Secondly, the installation and adjustment process of traditional steel beams requires a lot of time and manpower, affecting the progress and cost of the project. In addition, fixed-size steel beams may not be able to fully utilize materials during the construction process, resulting in material waste and increased costs. Therefore, we propose a telescopic steel beam that is easy to construct. Through ingenious structural design, the length of the steel beam can be flexibly adjusted to meet the needs of different construction scenarios, reducing the workload of on-site cutting and adjustment, thereby improving construction efficiency and material utilization, and enhancing its practicality in actual use.

In this way, the spring pieces 18 of the two sub-frames 11 in the mother frame 17 will be compressed, so that there is elastic force between the spring pieces 18 and the first spring 15, so that there will be a certain supporting force when used for construction. In this way, the staff can apply the telescopic steel beam in more different scenarios, and there is no need to cut the steel beam suitable for use according to different environments, which saves a lot of time, thereby improving its practicality in actual use.

[0028] Example 2

[0029] like Figure 1-4As shown, a fixing mechanism 2 is provided on the mother frame 17, and the fixing mechanism 2 includes a connecting plate 21, a screw 22 is provided on the connecting plate 21, and a second spring 23 is provided on the outer surface of the screw 22. One side of the connecting plate 21 is in contact with the outer surface of the mother frame 17, and the outer surface of the screw 22 is fixed to the sub-frame 11 by passing through the connecting plate 21 by threaded rotation, and the two ends of the second spring 23 are respectively fixedly connected between the screw 22 and the connecting plate 21.

At this time, the spring sheet 18 of the sub-frame 11 in the mother frame 17 will be compressed, thereby generating elastic force between the spring sheet 18 and the first spring 15, providing a certain support force for construction. In this way, the staff does not need to cut the steel beam according to different environments, which can save a lot of time, and the telescopic steel beam can be applied to more different scenarios.

During the adjustment process, the screw 22 will compress the second spring 23, thereby forming a buffering protective force between the screw 22 and the connecting plate 21. This design not only improves the stability of the structure, but also improves the overall reliability and safety of the telescopic steel beam in actual use.
