Abstract

The utility model relates to building material field, concretely to a bamboo glued wood which uses the ring bamboo section cut from the bamboo stalk as the clamp core, and uses the double-face bamboo piece as the plywood. The outer two layers plywood is a thin bamboo plate which is formed by bonding the bamboo pieces dissected longitudinally from the bamboo; the middle clamp core material is the ring bamboo section cut from the bamboo stalk; the cross-sections on the two ends of the bamboo section is applied with the tackifier, and is bonded with the outer two layers plywood and are compressed under the high temperature and the high pressure, thereby making up the middle core materical. The thickness of the product is due to the height of the ring bamboo section, and the board strength and density is decided by the thin or thick arrangement of the ring bamboo section. The room door board and the baffle made of the utility model are not only durable, but also waterproof, and resist corruption, and the resistant deformability is satisfied.

Description

A kind of bamboo plywood

Technical field

The utility model relates to building material field, specifically refers to use from the culm intercepting ring-type ring of bamboo make a kind of bamboo plywood that sandwich, two-sided slim bamboo chip are made clamping plate.

Background technology

China is the abundantest country of bamboo resource in the world, and the bamboo total output accounts for the world 60%.Therefore bamboo wood and bamboo product processing industry are big industries of China the south of the lower reaches of the Yangtze River.Trees be under an embargo felling and the situation of conceding the land to forestry under, bamboo is fast with its breeding, speed generates material and be used as the object of falling over each other to develop by people.The comprehensive utilization problem of a bamboo is just in China's vast bamboo wood producing region broad research.Some places bamboo product is processed get off rejectable waste--the sheet of lamination is processed in the hot pressing such as-bamboo tip, bamboo bamboo grove, be widely used in building template, the carriage bottom plate of automobile, train etc. have not only been saved great deal of steel and timber, and water-fast, corrosion resistance good, cost is low.But general this class glued board general thickness is not thick owing to cost and weight, and between several millimeters to 25 millimeters, as door-plate one series products that will make the 4-5 cm thick, the centre just must embed certain thickness batten and could make usually.Can someone advise bamboo wood directly being processed into and both reached above-mentioned thickness, the bamboo plywood that weight is light again, cost is low, invention original intention of the present utility model that Here it is.

The utility model content

The purpose of this utility model is: with bamboo development make a kind of more abundant relatively, in light weight, cost is low, and the bamboo plywood of certain intensity is arranged again, is used for making the door-plate, furniture table in house etc.

The utility model technical solution problem technical scheme is: utilize the big characteristics of bamboo longitudinal stress intensity, culm is intercepted into one section one section ring-type ring, sandwich between the slim bamboo chip in two sides and make sandwich material, and be bonded with it.The utility model is made from the bonding back of ring-type ring, lower floor's bamboo clappers of culm intercepting static pressure under HTHP by upper strata bamboo clappers, plurality of sections.Described bamboo clappers is vertically to cut open the thin slice that is whittled into by bamboo to be spliced into large-area thin plate.Described ring-type ring intercepts from culm, and its size arbitrarily but highly must be unified, can be regular or irregular alignment between two-layer thin plate.The two ends cross section of ring-type ring is bonding with the two slim bamboo clappers in outside respectively.Because bamboo can bear bigger power in vertical direction, therefore the bamboo plywood strength ratio that is pressed into the utility model version is higher.

Because of clamping plate of the present utility model inside has similar cellular structure, and can require to intercept the height of ring-type ring according to different-thickness, the mode of arranging on thin plate is also more random, therefore the requirement of strength and the density of sheet material can increase and decrease with the mean number of ring-type ring in the unit are, to make the bamboo plywood of different-thickness and density.Because the shape size of ring is not limit, the corner of some bamboos, clout can both be fully used, so the product of its a kind of resource-conserving really.

Description of drawings

Fig. 1 is a cross-section cutaway view of the present utility model:

Fig. 2 is a three-dimensional internal anatomy of the present utility model;

Each title and mark among the figure: 1. upper strata bamboo clappers, 2. ring-type ring, 3. lower floor's bamboo clappers, 4. adhesive.

The specific embodiment

As depicted in figs. 1 and 2, this product forms by sandwiching the bonding hot pressing of ring-type ring that intercepts from culm in the middle of the two-layer slim bamboo clappers.The slim bamboo clappers on its two sides vertically cuts open the bamboo chip splicing that is whittled into by bamboo and makes.The thickness of slim bamboo clappers generally is not more than three millimeters, and the height of ring-type ring 2 is looked the thickness requirement decision of product.Following cross section coated with adhesive 4 with ring-type ring 2 is arranged on lower floor's bamboo clappers 3, and coated with adhesive 4 on cross section on the ring-type ring 2 is spread upper strata bamboo clappers 1 then again, under HTHP static pressure after a period of time described bamboo plywood.With this production door-plate or furniture the time, the ring-type ring 2 that exposes on its section can be with bonding the sealing of banded bamboo bar.

Claims

1. bamboo plywood, by two-sided clamping plate and middle bonding the forming of laminboard layer, it is characterized in that: described superficial layer is upper strata bamboo clappers (1) and lower floor's bamboo clappers (3), the therebetween core material is the ring-type ring (2) that intercepts from culm, described upper strata bamboo clappers (1) and lower floor's bamboo clappers (3) are vertically cutd open bonding being spliced of slim bamboo chip that is whittled into by bamboo, described several ringlike ring (2) becomes the arranged vertical setting with the plane of upper and lower layer bamboo clappers (1) (3), and on its two end section coating adhesive (4), bonding with upper and lower layer bamboo clappers (1), (3).
