Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit engineering, in particular to a fixing structure of double-jointed I-beams. Background Art

[0002] In the current temporary construction support system, double-jointed I-beams are widely used as a common distribution beam. They carry and transmit the load of the upper construction structure, and their stability and connection strength are crucial. However, the current conventional technical means mainly rely on bar welding and contact surface spot welding to fix double-jointed I-beams, which has obvious disadvantages and limitations.

[0003] First, in terms of construction efficiency, the process of welding the auxiliary bars and spot welding the contact surfaces is cumbersome and time-consuming, which prolongs the entire construction period and requires a large investment in manpower and material resources. Secondly, the welding connection method shows low flexibility in practical applications, especially in situations where space is limited or frequent position adjustments are required. It is difficult for workers to quickly complete the connection and disassembly of double-piece I-beams, which directly affects the project progress and the overall construction rhythm.

[0004] In addition, the welding fixation method is subject to the on-site power supply and climatic conditions, such as wind and other factors, which may cause unstable welding quality or even make it impossible to perform welding operations normally, further increasing the construction risk. In addition, the double-jointed I-beam fixed structure after welding is often difficult to disassemble and reuse, resulting in serious waste of resources, which is contrary to the circular economy and green construction concepts advocated today, and increases construction costs and environmental pollution. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing structure for double-jointed I-beams to overcome the limitations of the prior art in terms of construction efficiency, flexibility, environmental adaptability, economy and environmental protection, so as to achieve efficient, flexible, reliable and sustainable fixing of double-jointed I-beams.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] A fixing structure for a double-jointed I-beam, comprising a fixing frame for transversely restraining the double-jointed I-beam, wherein the fixing frame is a quadrilateral frame, the distance between the left frame and the right frame of the quadrilateral frame is equal to the maximum transverse dimension of the double-jointed I-beam, and the distance between the upper frame and the lower frame of the quadrilateral frame is equal to the maximum vertical dimension of the double-jointed I-beam;

[0008] At least one frame of the fixed frame is provided with a telescopic element.

[0009] Furthermore: the telescopic element is arranged on the left frame and / or the right frame of the fixed frame.

[0010] Furthermore: the frame provided with the telescopic element is divided into a separate first section and a second section, and the telescopic element is connected between the first section and the second section; the telescopic element includes a nut block rotatably connected to the first section and a threaded rod fixedly connected to the second section, and the nut block and the threaded rod are threadedly connected.

[0011] Furthermore: the nut block is connected to the first section through a fixed seat welded on the first section and a rotating rod rotatably installed in the fixed seat; a rotating groove is provided on the fixed seat, a rotating disk is fixed at one end of the rotating rod, and a threaded sleeve is fixed at the other end of the rotating rod, the rotating disk is rotatably installed in the rotating groove, the threaded sleeve is threadedly connected to the threaded rod, and the nut block is fixedly connected to the rotating rod.

[0012] Furthermore: adjacent frames of the quadrilateral frame are connected via a rotating shaft hinge.

[0013] Furthermore, the rotating shaft hinge includes latch holes at both ends of the frame and latches in the latch holes, the latch holes at the ends of adjacent frames are located at corresponding positions, and the latches penetrate the corresponding latch holes.

[0014] Furthermore: the material of the latch is galvanized steel.

[0015] Furthermore: the fixing frame is made of stainless steel.

[0016] Furthermore, the four corners of the quadrilateral frame are provided with soft gaskets to protect the four stress concentration corners where the double-jointed I-beams contact the fixed frame, and in addition, to fill some of the size gaps between the fixed frame and the double-jointed I-beams, so that the fixed frame can bind the double-jointed I-beams more tightly.

[0017] Compared with the original technology, the utility model has the following beneficial effects:

[0018] 1. By using the utility model, the method of fixing the double-jointed I-beams by mechanically tightening the frame with bolts replaces the method of welding the joints between the double-jointed I-beams, which simplifies the operation process of fixing and splitting the double-jointed I-beams, greatly shortens the construction time, and significantly improves work efficiency.

[0019] Second, by applying the utility model, the dependence on electricity and a windless and rainless working environment is abandoned, so that the operation of fixing double-jointed I-beams can be carried out smoothly under a wider range of conditions, reducing construction delays or difficulties caused by environmental factors.

[0020] 3. The disassembly and recycling characteristics of the utility model not only save material costs and reduce waste generation, but also comply with the sustainable development principles of the construction industry and enhance the economic and environmental benefits of the project.
