Lightweight high-strength plug-in composite floor

Abstract

The invention relates to a lightweight high-strength plug-in composite floor. The lightweight high-strength plug-in composite floor comprises a surface plate, a middle layer arranged below the surface plate and a bottom plate arranged below the middle layer, wherein one end of the middle layer is provided with an edge-sealing aluminum beam; the edge-sealing aluminum beam is internally provided with a rectangular hollow cavity; a plug-in strip is mounted in the rectangular hollow cavity in a clearance fit manner; and the plug-in strip is provided with rectangular bulges. A molding process for the composite floor is an advanced preparation technology for composite materials. According to the invention, fiber cloth is laid on the upper and lower surfaces of a foam board as needed; related auxiliary materials are placed in a vacuum bag; materials in a resin tank are introduced to a place located between a fibrous layer and foam and allowed to wet the fibrous layer in virtue of a vacuum technology; and then high-temperature curing is carried out in a baking oven. A production method for the composite floor has the characteristics of simple process and high machining 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
