Description

Technical Field

[0001] This invention relates to the field of wind power tower structure engineering technology, specifically to a prefabricated double-layer arc-shaped metal lattice sandwich panel concrete component. Background Technology

[0002] With the development of wind power in my country, the single-unit capacity and tower height are getting larger and larger, becoming a trend in the wind power industry in recent years. Increasing the tower height is considered a direct and effective means to increase power generation in low wind speed areas. The manufacturing and transportation costs of traditional steel towers have risen sharply, and they do not meet the load-bearing requirements. The height of traditional steel towers does not exceed 120m, and there is an urgent need for new structural forms to increase the tower height. The height of steel tower + concrete tower (steel-concrete tower) can reach 140-185m. When the wind turbine is running, the downward force transmission of the tower top is uneven, generating shear force on the concrete tower. Local stress concentration leads to safety hazards such as concrete tower cracking, outer wall spalling, and peeling. The conventional solution is to use high-grade concrete, such as C150 concrete, and add copper-plated steel wire fibers inside the concrete to increase the strength of the concrete tower and reduce the risk of cracking. However, the production cost of this concrete tower is high.

[0003] A concrete tower is composed of concrete tower components. Several concrete tower components are joined together by bolts or adhesives to form a concrete tower cylinder. Multiple concrete tower cylinders are joined together by adhesives to form a tall concrete tower. The installation process of this concrete tower is complex, the installation accuracy is difficult to control, and the construction period is long. Summary of the Invention

[0004] This invention provides a prefabricated double-layer curved metal matrix sandwich panel concrete component, which solves the industry pain points of existing concrete tower fabrication and installation. It has low manufacturing cost, convenient installation process, easy control of installation accuracy, short construction cycle, and is suitable for mass production. It can pre-assemble dovetail tenons on both sides and glue the top and bottom tenons together. The splicing and butt joint strength of the double-layer curved metal matrix sandwich panel concrete component is higher. The structure of this invention is simple, eliminating the need for on-site welding, rebar tying, and concrete pouring. The staggered assembly construction is convenient, the installation is fast and efficient, the connection strength is high, and the stress is continuous and reliable.

[0005] The present invention provides the following solution: a prefabricated double-layer curved metal matrix sandwich panel concrete component, comprising a double-layer curved metal matrix sandwich panel and concrete filling the double-layer curved metal matrix sandwich panel.

[0010] Preferably, the arc lengths of the outer arc metal plate and the inner arc metal plate are determined by dividing the entire circle of their respective radii into several equal parts.

[0025] The double-layer arc-shaped metal matrix sandwich panel includes an outer arc-shaped metal plate 1, an outer arc-shaped metal plate 101 with its circumferential upward end face, an outer arc-shaped metal plate 102 with its circumferential downward end face, a metal plate dovetail tenon 103, a metal plate dovetail mortise 104, an inner arc-shaped metal plate 2, an inner arc-shaped metal plate 201 with its circumferential upward end face, an inner arc-shaped metal plate 202 with its circumferential downward end face, and a metal matrix sandwich body 3.

[0026] The concrete, including concrete 4, is of various grades.

[0027] Application Examples The outer arc-shaped metal plate 1 is formed by folding the edges of a flat metal plate into a closed shape. It is then rolled into an arc-shaped metal plate with folded edges, following the direction of the two vertical edges towards the center of the arc, according to the designed radius. The outer arc-shaped metal plate 101, facing upwards, is rolled into an arc-shaped metal strip according to the designed radius. The outer arc-shaped metal plate 102, facing downwards, is rolled into an arc-shaped metal strip according to the designed radius. The dovetail tenon 103 on one axial side of the outer arc-shaped metal plate is bent into shape according to the designed dimensions. The dovetail mortise 104 on one axial side of the outer arc-shaped metal plate is bent into shape according to the designed dimensions. The metal dot matrix sandwich body is manufactured from metal rods according to the designed dimensions and shape. The outer arc-shaped metal plate 1 has two circumferences facing upwards and downwards. The inner arc metal plate 2 is welded to the outer arc metal plate circumferentially upward end face metal plate 101 and the outer arc metal plate circumferentially downward end face metal plate 102 respectively. The inner arc metal plate 2 is formed by folding the edges of the metal plate into a closed shape, and is rolled into an arc metal plate with folded edges according to the design radius size along the two vertical edges of the arc circumferentially away from the center of the arc.
