Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, a fully assembled hollow interlayer concrete-filled steel tube composite tower and nodes, the system is mainly composed of hollow interlayer concrete-filled steel tube tube body (1), transverse nodes (2), and longitudinal nodes (3). The hollow interlayer concrete-filled steel tube body (1) is divided into 2 to 8 pieces along the circumferential direction, and adjacent pieces are assembled and connected by transverse nodes (2); the hollow interlayer concrete-filled steel tube body (1) is assembled in sections along the height direction, and the They are connected by vertical nodes (3).

[0026] Such as figure 2 As shown, the hollow interlayer concrete tube body (1) is composed of an outer steel tube (4), an inner steel tube (5) and concrete (6). The cross-sections of the outer steel pipe (4) and the inner steel pipe (5) gradually be...

Abstract

The invention discloses a totally-assembled type hollow interlayer steel pipe concrete combined tower barrel and joints, and relates to the technical field of wind power generation. The system comprises a hollow interlayer steel pipe concrete barrel body, transverse joints, longitudinal joints and corresponding structures. The hollow interlayer steel pipe concrete barrel body is composed of an outer-layer steel pipe, an inner-layer steel pipe and concrete, studs, angle iron, T-shaped steel or the combination of the studs, the angle iron, the T-shaped steel is welded to one side of each steel pipe in advance, and then concrete pouring is conducted. The hollow interlayer steel pipe concrete barrel body is divided into 2-8 sheets in the ring direction, connection is conducted through the transverse joints, and two forms are adopted in the transverse joints. Segmented assembling of the hollow interlayer steel pipe concrete barrel body in the height direction is achieved, various segments are connected through the longitudinal joints, and two forms are adopted in the longitudinal joints. According to the system, the advantages of a combined structure are brought into full play, the stress form is reasonable, and joint connection is reliable. All the components can be prefabricated in advance, field assembling is adopted, transportation is convenient, the construction efficiency is improved, the material usage amount is reduced, and wide project application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of wind power generation. Background technique [0002] Wind power is a non-polluting, renewable and clean energy. Wind farms have high power generation, stable wind turbine operation, and mature manufacturing technology, and have been widely used in recent years. [0003] With the increasing demand for wind power energy, high-power, high-tower wind turbines are becoming more and more mainstream. Traditional wind turbines mostly use pure steel towers. In order to meet the requirements of stability, strength and fatigue, the diameter and wall thickness of the towers are generally large, resulting in waste of materials and difficult construction. Therefore, it is necessary to optimize and innovate the tower form. Contents of the invention [0004] The invention proposes a fully-assembled hollow interlayer concrete-filled steel tube composite tower tube and nodes: the system includes a hollow interlayer co...
