Abstract

The utility model relates to a bamboo and China fir composite floor board. The utility model is characterized in that a panel and a backplane are made from bamboo, and a core board is made from Chinese fir which is pressurized and glued in multi-way after assembled. The utility model makes full use of beautiful patterns of the surface of the bamboo and the high physical properties of the bamboo, and adopts large quantity of Chinese firs to be used as the core material of the floor board; thus, the utility model has the advantages of low cost and low bamboo consumption. Since the utility model uses the excellent physical properties of allometry Chinese firs, not only the texture, the flatness and the corrosion resistance of the utility model are improved obviously, but also the fragrance of sesquiterpene, terpene, ester, etc., which is emitted from the Chinese firs is favorable to the health of human bodies.

Description

Bamboo and China fir composite floor

The utility model belongs to bamboo and wood products's production technology.

China's bamboo timber resource is abundant, along with people's progressively paying attention to and to the further investigation of bamboo wood self character, developed various bamboo materials flooring product and patented technology, as Bamboo floor blocks, the rectangular floor of all bamboo structure and bamboo plywood etc. bamboo utilization.Bamboo floor has been subjected to welcome at home and abroad with its distinctive texture and excellent physical property.But characteristics such as because bamboo compares with timber, have that the footpath level is little, taperingness big on form, hollow, wall are thin, the volume recovery when processing above-mentioned all kinds of Bamboo floor is lower, and comprehensive benefit is not high enough.The combination of flooring material also has the possibility of the raising of improving.

Purpose of design of the present utility model is, give full play to the advantage of bamboo wood aspect surface texture and physical property and the good physicochemical characteristics of China fir, make the ground board core material with China fir [Cunninghamia lanceolata (Lamb.) Hook.], make floor surface with bamboo wood and decorate material, to obtain low cost, high performance novel bamboo and China fir composite floor.

Technical solution of the present utility model is: panel (1) and base plate (3) adopt bamboo wood, and central layer (2) adopts China fir.

Because the utility model has made full use of the characteristic that the bamboo wood surface detail is attractive in appearance, physical property is higher, adopted the China fir that forest zone, China south accumulation is big, wood property is good as core material again in a large number, therefore, the utility model has not only still kept the good functional performance on the rectangular floor of all bamboo structure, the cost on floor is reduced greatly, and the bamboo wood consumption also has obvious decline.Simultaneously, because the utility model has utilized the good physical of China fir, fir essential oils such as the sesquiterpenoids that includes, terpene alcohols, ester class can volatilize strong fragrance, and have natural pest-resistant, rotproofness.Therefore, bamboo and China fir composite floor not only its texture, planeness and rotproofness has clear improvement than all bamboo structure floor, according to reports, delays senility, is beneficial to the able-bodied auxiliary effect of human body in addition.

The description of the drawings:

Fig. 1 is the cross section structure schematic diagram of bamboo and China fir composite floor; The panel that be processed into for bamboo chip (1) among the figure, the central layer that be processed into for China fir (2), the base plate that be processed into for bamboo chip (3).

Exemplary embodiments:

Bamboo is blocked, is processed into by stripping-cutting machine the wide bamboo bar that is about 1m, wide about 25mm; Making thickness behind four side moulder force plane, poach, drying, adjustable cast iron planes is the refining bamboo chip of 5.5～6.0mm.Behind the wafer separator burst, be processed into the thin bamboo plate that thickness is 2.2～2.5mm again.Wherein bamboo strip is done panel (1) use, and yellow bamboo face is made base plate (3) and used.It is that the plank of 12～14mm is made central layer (3) that China fir is processed into thickness.The four sides up and down of central layer (3) coated behind the urea-formaldehyde resin adhesive form slab with surface layer, bottom bamboo chip, it is whole every bamboo China fir composite plate to adopt two-way pressing mode to compose again.Scrape, can obtain after the sanding, fluting, mortise the rectangular four sides tongue and groove bamboo and China fir composite floor of length * wide-90 * 910mm through sawing, surface.

Claims

1. one kind is the bamboo compound floor that raw material is made with bamboo wood and timber, it is characterized in that panel (1) and base plate (3) adopt bamboo wood, and central layer (2) adopts China fir.
