Fiber-reinforced polymer matrix composite assembled floor

Abstract

The invention relates to a fiber-reinforced polymer matrix composite assembled floor, comprising a plurality of floor units made from fiber-reinforced polymer matrix composite materials and board fixing pieces which are used for matching and splicing two adjacent floor units and made from other materials, wherein the floor units comprise wing plates extending outwards along the bottom edges of the two sides and the board fixing pieces are arranged on the wing plates of the two adjacent floor units via lap joint and fixedly connected with a base for carrying the floor units through screws. The assembled floor disclosed by the invention has the characteristics of excellent processing intellectualization, good mechanical property, environmental protection, light weight, convenience and rapidness in installation, capability of satisfying use habits and the like.

Description

technical field [0001] The invention relates to an assembled floor, in particular to a floor unit made of fiber-reinforced polymer-based composite material and a floor assembled from the floor unit through fixing parts made of other materials. Background technique [0002] At present, the floors of containers, vehicles and ships mainly include plywood, solid wood integrated floor and steel floor, and wood plywood is the main one. Conventional containers, vehicles and ship floors all have the following practical problems or obstacles. [0003] 1. Environmental protection issues: reflected in two aspects: first, the current floors of containers, vehicles and ships are mainly wooden floors. As we all know, hardwoods mainly come from tropical rainforests. The contradiction between the scarcity and the high demand is getting bigger and bigger. Second, the production of wood flooring requires boilers to provide energy. VOC emissions from boilers are an important source of pollut...

AI Technical Summary

Problems solved by technology

[0003] 1. Environmental protection issues: reflected in two aspects: first, the current floors of containers, vehicles and ships are mainly wooden floors. As we all know, hardwoods mainly come from tropical The impact of large-scale disappearance of rainforest on the environment is becoming more and more obvious, and the contradiction between the scarcity of resources and the large demand is getting bigger and bigger

[0004] 2. Obstacles to energy saving: In terms of transportation, the floor density of traditional wooden containers, vehicles and ships is about 800KG / cubic, resulting in an increase in the overall weight of containers, vehicles and ships , whether it is vehicle transportation or seagoing transportation, energy is wasted, and the direction of lightweight floors such as containers, vehicles and ships is the general trend

In terms of production energy consumption, the production energy consumption cost of conventional wood flooring is relatively high

[0005]Third, the manufacturing process is cumbersome: traditional wooden plywood is made of wooden veneers ranging from several layers to dozens of layers according to the corresponding billet structure, which is heated by a hot press machine. It is made by pressing and gluing. The product needs dozens of processes to complete. The process is cumbersome, the production efficiency is low, and there are many human factors, which is not conducive to the improvement of product stability; the production of steel flooring is relatively simple, but due to its lack of Corrosion resistance, variability, high cost and other issues and gradually eliminated

[0006] 4. Problems with the installation method: the floors of containers, vehicles and ships are usually fixed by self-tapping screws or welded. For example, a 53-foot container needs about 1,500 screws. The installation process is to lay the floor on the chassis with equipment or manually, and then manually insert the solder for positioning, draw lines and drill holes, spread nails, and fasten. High labor intensity, high demand for personnel, and low production efficiency

And after the screw position is drilled, the screw hole will destroy the continuity of the fiber and will become the weakest link of the whole component. The impact of fatigue performance is very significant, therefore, the conventional screw fastening method is an important factor in the increase of maintenance costs in the later period

[0007] V. Obstacles to lowering the cost of use: The cost of using floors such as conventional containers, vehicles and ships is more prominent in the cost of container removal and maintenance costs

One of the main reasons for the high maintenance cost is that the floor somewhere in the box is damaged, often the entire floor is replaced, and the original nail holes must be repaired and then drilled and locked.
