Abstract

The invention relates to a dot matrix coreboard, panel strips for preparing a core and a preparation method of the coreboard, and particularly relates to a pyramid-shaped dot matrix sandwich panel with a transverse bar, panel strips for preparing a core and a preparation method of the coreboard. The invention aims to solve the problems of the traditional dot matrix coreboard that structural mechanical performance is poor, the interlocking assembly is difficult to implement and has big error during a preparation process and adhering areas between the core of the dot matrix coreboard and upper and lower panels are small. The dot matrix coreboard provided by the invention comprises an upper panel, a core and a lower panel; upper and lower surfaces of the core are respectively adhered to the upper and lower panels; and N upper panel strips and N lower panel strips are connected with each other through the mutual occlusion of a first upper clamping slot and a first lower clamping slot and the mutual occlusion of a second upper clamping slot and a second lower clamping slot, thereby completing interlocking assembling to form the core. The dot matrix coreboard provided by the invention is applied to the field of engineering works.

Description

technical field [0001] The invention relates to a dot-matrix sandwich panel, a fillet for preparing the core and a preparation method, in particular to a pyramid-shaped dot-matrix sandwich panel with transverse ribs, a fillet for preparing the core and a preparation method. Background technique [0002] The lattice sandwich structure is a new type of structure designed to meet the requirements of lightweight and multi-functional engineering structures. The existing lattice sandwich panel is not an integral structure because the lattice sandwich core is not an integral structure, and the bonding area with the upper and lower panels Smaller, so the mechanical properties of the structure are poor. [0003] At present, the interlocking method is mainly used for the preparation of dot matrix sandwich panels. Because the interlocking height is too small, the equipment is difficult and the error is too large. The mouth will cause great damage to the laminate, and the bonding area ...
