Problems solved by technology

[0003] When realizing the molding preparation of the grid-type reinforced structure, it is often necessary to prepare a variety of molds for different parts of the horizontal / vertical / oblique ribs to be molded separately, which consumes a lot of mold costs, material costs, and time costs. It is difficult to achieve uniform quality control among

Embodiment 1

[0046] refer to Figure 1 to Figure 4 , the present embodiment discloses a modular composite material reinforcing rib structure, which is formed by splicing a plurality of reinforcing rib modules, and each reinforcing rib module includes a reinforcing rib main body 1 and two connecting heads 2 connected to the reinforcing rib main body 1 .

[0047] The reinforcing rib body 1 has a linear shape, including a main body flange 101 and a main body beam rib 102. The main body flange 101 and the main body beam rib 102 are vertically arranged. In this embodiment, the cross section of the reinforcing rib body 1 is T-shaped structure, that is to say, each reinforcing rib main body 1 includes a main body flange 101 and a main body beam rib 102. The main body beam rib 102 is mainly used for bearing and improving the overall rigidity of the structure. The main body flange 101 is mainly used for For the connection function, the reinforcing rib main body 1 is connected and fixed with the ex...

Embodiment 2

[0053] The rest of this embodiment is the same as that of Embodiment 1, the difference is that refer to Image 6 , in this embodiment, each connector 2 is connected with the connector 2 on 2 different reinforcing rib modules to form a circular connecting portion, that is, the connecting portion is formed by connecting 3 different reinforcing rib modules. In the example, when three different reinforcing rib modules are connected, the reinforcing rib main bodies 1 on each reinforcing rib module are arranged at 120° to each other, such as: Figure 7 As shown, the reinforcing rib formed between such a plurality of reinforcing rib modules forms a grid-like reinforcing rib with a hexagonal structure.

Embodiment 3

[0055] refer to Figure 8 and Figure 9 , the rest of this embodiment is the same as in Embodiment 1, the difference is that in this embodiment, each connector 2 is connected to the connector 2 on 5 different reinforcing rib modules to form a circular That is, the connecting portion is formed by connecting 6 different reinforcing rib modules. In this embodiment, when 6 different reinforcing rib modules are connected, the reinforcing rib main bodies 1 on each reinforcing rib module are arranged at 60° to each other, so that a plurality of reinforcing ribs The reinforcing ribs formed between the modules form a grid-like reinforcing rib with a triangular structure.

Abstract

The invention discloses a modular composite material reinforcing rib structure and a rib plate, the reinforcing rib structure is formed by splicing a plurality of reinforcing rib modules, and each reinforcing rib module comprises a reinforcing rib main body and two connectors connected with the reinforcing rib main body; different reinforcing rib modules are mutually connected through connectors, each connector is connected with at least two connectors to form a connecting part, and the connectors in each connecting part belong to different reinforcing rib modules; and the reinforcing rib plate is formed by covering or installing a composite material plate on one side or two sides of the reinforcing rib structure. The reinforcing rib structure is formed in a modular splicing mode, can be assembled into a periodic circulation structure, is high in universality, improves the production and assembly efficiency, is convenient to maintain and replace, and improves the product quality consistency.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a modular composite material reinforcing rib structure and a rib plate. Background technique [0002] Composite reinforced structures are widely used in aerospace, wind power generation, rail transit and many other fields, and have the characteristics of light weight, high strength, excellent corrosion resistance and environmental resistance, such as aircraft wing structures, fuselage structures, wind power blades, etc. materials and structures. [0003] When realizing the forming and preparation of the mesh reinforced structure, it is often necessary to prepare a variety of molds for different parts of the horizontal / longitudinal / oblique stiffeners to be separately formed, which consumes a lot of mold cost, material cost and time cost. It is difficult to achieve uniform quality control between them. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is ...
