Lightweight high-strength plug-in composite floor

Abstract

The invention relates to a lightweight plug-in high-strength composite material floor, which comprises a panel, an intermediate layer is arranged under the panel, a bottom plate is arranged under the intermediate layer, an edge-sealing aluminum beam is arranged at one end of the middle layer, and the edge-sealing aluminum beam The inside is provided with a rectangular hollow, and the gap of the rectangular hollow is fitted with a plug-in strip, and the plug-in strip is provided with a rectangular protrusion. The molding process of composite panels is an advanced composite material preparation technology. Lay the fiber cloth on the upper and lower surfaces of the foam board as required for the panel, the middle layer and the bottom plate, and place the relevant auxiliary materials in the vacuum bag, and then use the vacuum process to introduce the resin tank between the fiber layer and the foam and wet it. The fiber layer is then cured in an oven at high temperature. It has the characteristics of simple process and high processing efficiency. 6063 aluminum alloy has the characteristics of light weight and high strength.

Description

technical field [0001] The invention relates to the field of floor technology, in particular to a light-weight plug-in high-strength composite floor. Background technique [0002] The sandwich structure is generally composed of the upper panel, the bonding layer between the upper panel and the core material, the core material, the bonding layer between the lower panel and the core material, and the lower panel. These five elements form an overall sandwich structure. The load transfer mode of the sandwich structure is similar to that of an I-beam. The upper and lower panels mainly bear the in-plane tensile and compressive stress and in-plane shear stress caused by the bending moment, while the core material mainly bears the shear stress caused by the lateral force. At present, floor core materials mainly include aluminum honeycomb, PVC foam, phenolic foam, extruded plastic board, etc., and some core materials have thermal insulation function to a certain extent.

AI Technical Summary

Problems solved by technology

[0005] Phenolic foam: there is a problem of poor adhesion, and the compressive strength is low, basically around 1MPa, which cannot balance strength and density

[0006] Extruded board: poor dimensional stability, deformation due to changes in temperature and humidity

Poor glue absorption, insufficient bonding strength, and compressive strength less than 1MPa

[0007] A commonality of existing laminate flooring core materials is that high enough density is required to achieve sufficient strength, which results in an increase in weight; or some core materials simply cannot meet the high strength requirements
