Embodiment Construction

[0027] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0028] Such as Figure 1~5 The shown composite lattice sandwich panel connection structure has a horizontal sandwich panel 2, and a vertical sandwich panel 1, a vertical sandwich panel 1 and a horizontal sandwich panel 2 are vertically arranged on the horizontal sandwich panel 2 A connector 3 is installed at the joint. The connecting piece 3 is located at the junction of the left and right sides of the vertical sandwich panel 1 and the horizontal sandwich panel 2 , so as to facilitate better transmission of force between the vertical sandwich panel 1 and the horizontal sandwich panel 2 .

[0029] The composite material lat...

Abstract

The invention discloses a composite material dot matrix sandwich plate connecting structure. The composite material dot matrix sandwich plate connecting structure is provided with a horizontal sandwich plate, a vertical sandwich plate is vertically arranged on the horizontal sandwich plate, and a connector is installed at the joint between the vertical sandwich plate and the horizontal sandwich plate; and the connector comprises a right-angle rib plate, the right-angle rib plate is composed of a first bottom plate and a second bottom plate, bent members are connected to the outer edges of the first bottom plate and the second bottom plate, and the first bottom plate, the second bottom plate and the bent members are spliced into a whole. The connecting structure has the characteristics of the high flexural rigidity, high load conduction capability, high integrity with a connected member and the like, and is suitable for mechanical connection of the composite material dot matrix sandwich plate in a large-scale structure.

Description

technical field [0001] The invention relates to a connection structure of composite material lattice sandwich panels, which is suitable for mechanical connection of composite material lattice sandwich panels in large structures. Background technique [0002] Composite lattice sandwich structure is a new type of structure with light weight, high specific strength, high specific rigidity and multi-functional potential. It is widely used in aircraft, missiles, rockets, hulls, locomotives, buildings, and sporting goods. [0003] Due to the limitations of its own characteristics and preparation process, the lattice sandwich structure rarely has complex shapes, and only regular shapes such as lattice sandwich panels and lattice sandwich tubes are common. But engineering applications go far beyond these regular structures, and lattice sandwich structures require complex shapes to meet more demands. It is difficult to change the shape of the lattice sandwich structure through the p...
