Description

Technical Field

[0001] This utility model relates to the field of wind power foundation construction technology, and in particular to a control device for a reusable steel reinforcement protective layer for wind power foundations. Background Technology

[0002] Wind power is a clean energy source, characterized by its renewability, lack of pollution, high energy output, and promising future. Onshore wind turbine foundations typically employ a frustum-shaped foundation, with each section containing over 700 m³ of concrete and over 100 tons of reinforcing steel.

[0003] During construction, the complex binding of the reinforcing bars in the foundation makes it difficult to control the thickness of the protective layer. Furthermore, traditional reinforcing cages are supported by the ends of the reinforcing bars, which pose a risk of exposed reinforcing bars after the steel formwork is removed. Exposed reinforcing bars may rust and corrode, affecting the service life of the foundation. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a reusable steel reinforcement protective layer control device for wind power foundations that can effectively prevent internal steel reinforcement from being exposed outside the foundation, prevent corrosion of exposed steel reinforcement, and ensure uniform protective layer thickness during construction, thereby improving construction quality.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a control device for a reusable steel reinforcement protective layer for wind power foundations, comprising a horizontal control support and a vertical control support installed on a stepped steel formwork; the horizontal control support includes a horizontal reinforcement bar, which is installed on the horizontal surface of the stepped steel formwork, and a first steel reinforcement segment is welded below the horizontal reinforcement bar; the vertical control support includes a vertical foundation reinforcement bar, and the vertical direct contact reinforcement bar does not contact the vertical stepped steel formwork.

[0006] Preferably, the exterior of the step steel template is also provided with a detachable ring, the ring comprising multiple arc-shaped ribs, each arc-shaped rib having a tenon and mortise at both ends, and two adjacent tenons and mortises being fixed together by connecting bolts.

[0007] Preferably, one end of the horizontal reinforcing bar is welded and fixed to the inside of the arc-shaped reinforcing bar, and the other end extends toward the center of the template, with the bottom of the first reinforcing bar segment connecting with the surface of the stepped steel template.

[0008] Preferably, the vertical control support further includes a first vertical bar and a second vertical bar, and the vertical base bar, the first vertical bar and the second vertical bar are distributed in an equilateral triangle. The first vertical bar and the second vertical bar are fixed to the vertical base bar by welding with a second steel bar segment.

[0009] Preferably, the top of the vertical foundation reinforcement bar is also provided with a hook.

[0010] This utility model discloses a reusable rebar protective layer control device for wind power foundations, comprising a horizontal control support and a vertical control support mounted on a stepped steel formwork. The horizontal control support includes horizontal reinforcing bars, which are positioned on the horizontal surface of the stepped steel formwork, with a first reinforcing bar segment welded below each horizontal reinforcing bar. The vertical control support includes vertical foundation reinforcing bars, which do not contact the vertical stepped steel formwork. A detachable ring is also provided on the outside of the stepped steel formwork, comprising multiple arc-shaped reinforcing bars. Each arc-shaped reinforcing bar has tenon and mortise joints at both ends, and two adjacent tenon and mortise joints are fixed together by connecting bolts.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] Please refer to Figure 1-4 A reusable steel reinforcement protective layer control device for wind power foundations includes a horizontal control support and a vertical control support installed on a stepped steel formwork 1. The horizontal control support includes a horizontal reinforcement 3, which is installed on the horizontal surface of the stepped steel formwork 1. A first steel reinforcement segment 31 is welded below the horizontal reinforcement 3. The installation of the first steel reinforcement segment 31 can prevent the steel reinforcement cage above the horizontal reinforcement 3 from contacting the stepped steel formwork 1. After the concrete is poured, it can completely cover the internal steel reinforcement cage, preventing the steel reinforcement from being exposed.

[0020] The vertical control support includes a vertical foundation reinforcement 4. The vertical direct contact reinforcement 4 does not contact the vertical step steel formwork 1, thus preventing the reinforcement from being exposed after pouring.

[0021] During construction, a steel cage needs to be erected on the step steel formwork 1 to ensure the strength of the wind power foundation; while the setting of horizontal control supports and vertical control supports can prevent the steel bars of the internal steel cage from being exposed.

[0022] In other words, the steel cage is set above the horizontal reinforcement 3 and outside the vertical foundation reinforcement 4. After pouring, the concrete can completely cover the steel cage, horizontal reinforcement 3, and vertical foundation reinforcement 4. Since the space between the steel cage and the step steel formwork 1 is filled with concrete, the concrete can shield the internal steel cage and prevent the steel reinforcement from being exposed and corroded.

[0023] Before the concrete hardens, the horizontal reinforcement bars 3 and the vertical foundation reinforcement bars 4 are pulled out using excavators, wire ropes, etc., for reuse.

[0024] To increase the efficiency of installation and disassembly of the horizontal control bracket, a detachable ring is provided on the outside of the stepped steel formwork 1. The ring includes multiple arc-shaped ribs 2. Each arc-shaped rib 2 has a tenon and tenon buckle 21 at both ends. Two adjacent tenon and tenon buckles 21 are fixed together by connecting bolts 22. At least two horizontal ribs 3 have one end welded and fixed to the inside of the same arc-shaped rib 2, and the other end extends toward the center of the formwork. The bottom of the first steel bar segment 31 is in contact with the surface of the stepped steel formwork 1.

[0025] Before constructing the steel cage, horizontal reinforcement bars 3 can be evenly laid around the surface of the step steel formwork 1. When laying the reinforcement bars, multiple sections of curved reinforcement bars 2 can be connected. When removing the reinforcement bars, they can be pulled by an excavator or wire rope.

[0026] Please refer to Figure 5 After the steel formwork 1 of the step is installed, a height H is left between the surface of the step and the top of the circumference of the horizontal reinforcement 3. The height H is the thickness of the horizontal protective layer.

[0027] Therefore, after the concrete is poured, the concrete can cover the steel cage above the horizontal reinforcement 3 and fill the height H. When the steel formwork is removed, since there is also concrete in the height H, it will protect the internal steel cage and prevent the steel reinforcement from being exposed and corroded.

[0028] In this embodiment, the vertical control support also includes a first vertical rib 41 and a second vertical rib 42. The vertical base rib 4, the first vertical rib 41 and the second vertical rib 42 are distributed in an equilateral triangle. When in use, the first vertical rib 41 and the second vertical rib 42 contact the vertical outer wall of the step steel formwork 1. The first vertical rib 41 and the second vertical rib 42 are fixed to the vertical base rib 4 by welding through a second steel bar segment 43.

[0029] Please refer to Figure 6 After the vertical control support is installed, a distance L is left between the vertical outer wall of the step steel formwork 1 and the outer circumference of the vertical foundation reinforcement 4. This distance L is the thickness of the vertical protective layer.

[0030] Similarly, the steel cage is erected outside the vertical foundation reinforcement 4; after the concrete is poured, it will fill the interior of L. When the step steel formwork 1 is removed, since there is also concrete within the distance L, the internal steel cage will be protected to prevent the steel reinforcement from being exposed and corroded.

[0031] In other words, in this embodiment, the protective layer is concrete. The setting of horizontal and vertical control supports can create a gap between the steel cage and the steel formwork, allowing the concrete to fill the gap and prevent the internal steel bars from being exposed. At the same time, the evenly distributed horizontal and vertical control supports can effectively ensure the thickness of the protective layer, making the thickness of the protective layer in different locations consistent and ensuring construction quality.

[0032] As a preferred embodiment, the top of the vertical foundation reinforcement 4 is also provided with a hook 44, which facilitates the removal by excavator and telescopic traction.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
