Abstract

A honeycomb core splicing method comprises the following steps: inserting strip-shaped foaming glue satisfying a prescribed strength requirement between the honeycomb core groups or between the honeycomb core of a honeycomb panel and a frame skeleton, carrying out heating expansion of the foaming glue in a high temperature state of a hot pressed plate, carrying out synchronous hot pressing solidification with an adhesive or a glue membrane in the plate making process, and bonding the honeycomb core group or the honeycomb core and the frame skeleton which are butted into a whole body. The splicing method is simple to operate, is suitable for the splicing of honeycomb core groups, and is also suitable for the splicing and reinforcing of the honeycomb core and the frame skeleton; and additionally, the strength of a honeycomb core splicing position is higher than the strength of the body, so the honeycomb panel has a high overall strength and a good rigidity, and can satisfy strength requirements of a honeycomb shelter.

Description

technical field [0001] The invention relates to the technical field of shelters, in particular to a method for splicing honeycomb cores. Background technique [0002] During the panel making process of the honeycomb shelter, due to the width limitation of the honeycomb core and the specific production requirements, there must be splicing of the honeycomb core materials. [0003] At present, there are two methods of honeycomb core splicing: 1) manual sewing, which has the problems of low work efficiency and poor connection strength; 2) brushing adhesive, which has difficulties in aligning honeycomb holes and low connection strength, etc. question. The connection strength of the honeycomb core spliced ​​by the above two methods cannot meet the strength requirements of the honeycomb shelter. [0004] CN 102270782 A discloses a method for splicing reflective panels with a honeycomb sandwich structure, which includes three steps: determining the shape and positioning mode of th...
