Embodiment 1

[0041]A metal dot matrix board is characterized in that it comprises a dot matrix board (1), and the dot matrix board (1) includes an upper panel (2) and a lower panel (3) connected as one by a dot matrix core (4), so The lattice core (4) comprises a plurality of longitudinally arranged warp stringers (6) and a plurality of transversely arranged latitudinal stringers (5), and the warp direction stringers (6) and the weft direction stringers (5) Snap connection between each other.

[0042] The latitudinal stringer (5) is in the shape of a strip as a whole, which includes a plurality of continuous latitudinal isosceles triangle units (50), and the upper side of the latitudinal stringer (5) is provided with a plurality of openings upward The outer tenon groove (51) of the latitudinal stringer, the outer tenon groove (51) of the latitudinal stringer is arranged at the triangular apex position of the isosceles triangular unit (50) in the latitudinal direction, and the lower side of...

Embodiment 2

[0048] A novel method for manufacturing a metal dot matrix board connection, characterized in that it comprises the following steps:

[0049] 1) Prepare the upper panel (2) and the lower panel (3) according to the size of the lattice plate. For the lattice plate whose size is n*n (n is an integer multiple of a), the length of the weft stringers (5) is ax, the overhang length of the upper panel square mortise (20) is a / 2, the width is a, the groove depth of the tenon groove is a / 2, and the width is a, and the overhang length of the upper panel semi-square mortise (21) is a / 2, the width is a / 2, the mortise and mortise structures are arranged alternately along the entire joint direction, the mortise and tenon structures of the upper and lower panels of the same dot matrix board are interlaced, and the mortise and tenon structures of the dot matrix board connected to it should be Corresponding to it; its dimensions and structural schematic diagrams are shown in accompanying drawin...

Abstract

A metal lattice plate is characterized by comprising a lattice plate (1). The lattice plate (1) comprises an upper panel (2) and a lower panel (3), which are integrated by lattice cores (4) comprisinga plurality of vertically arranged warp-wise stringers (6) and horizontally arranged weft-wise stringers (5); and the warp-wise stringers (6) and the weft-wise stringers (5) are clamped and connectedto each other. Compared with a conventional connection mode, the provided metal lattice plate has the advantages that the discontinuity of the core structure in the lattice plate will not appear on asame end face, the anti-shearing performance of the lattice plate in the joints is improved; the joint welds of two lattice plates are all arranged in the cores of two lattice plates, the stability of the connection structure is improved, the core-free weld of a panel is avoided, and the mechanical properties of the lattice plate are improved.

Description

technical field [0001] The invention relates to the field of advanced manufacturing technology, in particular to a metal lattice plate and a manufacturing method thereof. Background technique [0002] The lattice sandwich structure has excellent specific strength and specific modulus and high multi-functional integration. ideal structure. However, the unique double-skin + space truss structure of the lattice sandwich structure makes its design method and manufacturing process quite different from the traditional structure. Among them, the design method and manufacturing technology of the connection joint of the lattice sandwich structure are the bottlenecks restricting the wide application of the lattice sandwich structure. At present, the connection of metal lattice plates on ship decks is mainly completed by a prismatic joint welded on one side. The structural diagram of this connection joint is shown in Figure 1 , but this connection method has many disadvantages. For ...
