Problems solved by technology

[0002] Existing sandwich panels include upper and lower panels and round tenons arranged in a lattice in the middle for support. The holes on the back of the upper and lower panels are determined according to the size of the lattice cells. When assembling, the round tenons are first connected with the first panel. All the holes on the panel are connected, and then connected to the second panel. The operation of the former is relatively simple, while the difficulty of the latter depends on the deviation value of the process parameters such as the size of the drilling hole and the hole position, which requires the processing accuracy of the drilling to be very high. High, but in reality it is difficult to guarantee the high precision of each hole, even if there is a problem with one hole, the assembly cannot be carried out
Therefore, it is very difficult to realize the straight-column lattice structure plate with traditional tenon-hole connection
For the sandwich panels with oblique column lattice structures such as V-shaped, triangular pyramid and quadrangular pyramid, it is impossible to use mortise and hole connections.

Embodiment 1

[0042] Figure 1 to Figure 4 The first embodiment of the sandwich panel with a lattice structure of the present invention is shown, including a pair of panels 1 arranged at intervals, and a plurality of suction cups 3 arranged in a lattice are connected to the inner surface of a pair of panels 1, and the two sides Each suction cup 3 is connected through the connecting column 2 . When the sandwich panel is assembled, the suction cups 3 are first fixed on the two ends of the connecting column 2 to form cells, and then the cells are arranged in a lattice along a pair of panels 1, so that each suction cup 3 is connected to the surface of the corresponding end panel 1. Form a permanent connection. Compared with the traditional structure, there is no need to drill holes on the panel 1 of the sandwich panel, the number of cells and the interval of each cell can be adjusted arbitrarily according to the strength requirements of the overall panel, and there is no precise fit of column ...

Embodiment 2

[0050] Figure 5 to Figure 8It shows the second embodiment of the sandwich panel with lattice structure of the present invention, the sandwich panel is basically the same as that of Embodiment 1, the only difference is that in this embodiment, two symmetrical Conical surface 34, two conical surfaces 34 are provided with socket holes 32, the center line of socket holes 32 is perpendicular to the corresponding cone surface 34, and the orthographic projection of one side suction cup 3 is located on the other side adjacent to the two suction cups 3 Between them and on the same straight line, the two socket holes 32 of one suction cup 3 are connected to the socket holes 32 of two adjacent suction cups 3 on the other side through two connecting columns 2 . In this structure, the two socket holes 32 of the suction cup 3 on one side are connected to the socket holes 32 of the two adjacent suction cups 3 on the other side through two connecting columns 2, that is, a V-shaped lattice st...

Embodiment 3

[0052] Figure 9 to Figure 10 Shown is the third embodiment of the sandwich panel with lattice structure of the present invention, the sandwich panel is basically the same as Embodiment 1, the only difference is: in this embodiment, in the overall core structure, each row and each A V-shaped lattice structure cell is formed in one column, and the V-shaped connecting columns 2 of the rows and columns are arranged in a cross, which improves the transverse shear strength.

Abstract

The invention discloses a laminboard of a lattice structure. The laminboard comprises a pair of panels which are arranged in a spaced manner. A plurality of suction discs arranged in a lattice are connected to the inner side surfaces of the pair of panels, and the suction discs on two sides are connected through connecting columns. The laminboard has the advantages of being simple in structure andconvenient to assemble.
