[0002] The fully reverse construction method typically involves the positioning and installation of bored cast-in-place piles, steel pipe columns, and concrete pouring. Traditionally, the steel pipe columns are connected to the guide steel columns by welding. Once construction is complete, the guide steel columns (also called guide columns) are difficult to remove due to welding and are often damaged and cannot be reused. Furthermore, direct contact between the concrete and the guide steel columns causes concrete to adhere to their surfaces, making them irrecyclable. These issues not only increase material costs and reduce construction efficiency, but also place an unnecessary burden on the environment. Utility Model Content

[0004] The utility model proposes a rotatable guide steel column, comprising: a guide column, a docking piece, a connecting piece and a protective layer; the lower end of the guide column is used to dock the upper end of the steel pipe column; the lower end of the guide column and the upper end of the steel pipe column are docked to form a docking seam; there are at least two groups of docking pieces, and the two groups of docking pieces are symmetrically arranged on both sides of the docking seam; each group of the docking pieces includes two fitted ear plates, and the two ear plates of each group of the docking pieces are respectively connected to the guide column and the steel pipe column; the connecting piece connects the two ear plates of each group of the docking pieces; the protective layer is arranged on the inner wall of the guide column.

[0005] Furthermore, the protective layer includes iron sheet; the iron sheet is fixed to the inner wall of the guide column.

[0006] Furthermore, the lower end of the protective layer is flush with the lower end of the guide column, and the height of the protective layer is greater than or equal to 0.5 meters.

[0007] Furthermore, the two lugs of each group of the docking parts are arranged upright and in parallel.

[0008] Furthermore, the middle parts of the two ear plates of each group of the docking parts are opposite to the docking seam; the upper part of one of the ear plates is connected to the guide column, and the lower part extends to one side of the steel pipe column; the lower part of the other ear plate is connected to the steel pipe column, and the upper part extends to one side of the guide column.

[0009] Furthermore, the connecting member includes matching bolt holes and high-strength bolts; a plurality of penetrating bolt holes are relatively arranged on the two ear plates of the docking member, and the high-strength bolts pass through the bolt holes to fix the two ear plates of the docking member.

[0010] The beneficial effects of the present invention are as follows: by providing a protective layer of a certain height near the lower end of the inner wall of the guide column, direct contact between the concrete and the guide column can be prevented, ensuring that the guide column will not be corroded by the concrete during the concrete pouring process, thereby maintaining the integrity of the structure and its removability in the later stage; by using the ear plate as a connector between the guide column and the steel pipe column, the guide column can be quickly disassembled and assembled according to the needs of the project, and the guide column can be reused in different construction sites, reducing resource consumption; the guide steel column of the present invention adopts a detachable bolt connection and iron sheet as a protective layer, so that the guide column can be completely disassembled and used in a turnover manner after the construction is completed, significantly reducing material costs and environmental impact.

[0015] The following is a further detailed description of this application with reference to the accompanying drawings and specific implementations:

[0016] like Figure 1-Figure 3 The illustrated guide steel column, which can be used reusably, comprises a guide column 2, a docking member, a connector, and a protective layer. The docking member comprises two lugs 3, and the connector comprises bolt holes 4 provided in the lugs 3 and high-strength bolts 5 extending through the bolt holes 4 of the lugs 3. The protective layer comprises iron sheet 6.

[0017] The steel pipe column 1 is connected to the guide column 2 via a lug plate 3, which is provided with bolt holes 4 for installing high-strength bolts 5. The wall surface within a height range of 0.5 meters below the guide column 2 is covered with iron sheet 6 to prevent direct contact between the concrete and the guide column. The iron sheet is fixed to the guide column via welds or clamps.

[0018] The lugs 3 are made of high-strength structural steel and are designed with multiple bolt holes 4 for installing high-strength bolts 5. In this embodiment, there are six bolts 5, evenly and symmetrically arranged on the lugs 3. The lugs were selected based on their ability to withstand pressure, vibration, and long-term use, ensuring the reliability of the entire connection system.

[0019] In this embodiment, the iron sheet 6 is made of galvanized steel or stainless steel, with a thickness ranging from 0.8 mm to 3 mm. This selection is based on its excellent protection and durability. This surface treatment not only provides an additional layer of corrosion resistance but also enhances durability against environmental factors, particularly in humid or saline environments. The iron sheet is secured via welds or clamps to ensure stability during construction and prevent loosening due to movement or vibration.

[0020] The construction steps are as follows: First, the iron sheet 6 is fixed to the lower inner wall of the guide column 2 at an appropriate location according to the design requirements. In this embodiment, it is within a height of 0.5 meters from the lower inner wall. This step is crucial because it ensures that the guide column is not corroded by the concrete during the pouring process, thus maintaining the structural integrity and subsequent removability. Next, the lugs 3 on the steel pipe column 1 and the guide column 2 are connected, ensuring that the bolt holes 4 are aligned, and then secured with high-strength bolts 5. These high-strength bolts are selected because they must withstand high loads and remain stable despite vibration and thermal expansion and contraction.

[0021] The construction design of the guide columns takes into account the ease and speed of construction, as well as the potential need for reuse at different stages or after the project is complete. The design of the guide columns 2 allows for easy removal after construction by unbolting the connections without damaging the structure, allowing for reuse or recycling – a key factor in saving costs and resources.

[0022] Furthermore, the structural stability and reusability of the guide steel columns facilitates faster overall construction. The guide columns 2 can be completely disassembled and reused after use, significantly reducing material costs and environmental impact. This allows for multiple reusable guide columns, further enhancing the protection and safety of finished products. Furthermore, the removable structure significantly improves work efficiency and saves costs.

[0023] The guide steel columns of this utility model not only provide an effective way to protect the guide columns and ensure they can be removed and reused after construction, but also bring new solutions to the construction industry, promoting efficient construction processes and environmental sustainability. Through this innovative design, the utility model solves many problems existing in traditional construction methods, such as low construction efficiency, low resource utilization, and large environmental impact, demonstrating how technological advancements can provide significant economic and environmental benefits in practical applications. Material costs and environmental impact. This design not only optimizes material use and reduces costs, but also meets the requirements of sustainable development. The guide steel columns' ability to be used multiple times ensures efficient operation of the construction site while also reducing the environmental burden during the construction process.
