Abstract

A bamboo-wood composite block board after the production procedures of glue spreading, assembly and hot pressing is characterized in that the interface layer takes bamboo mat and bamboo blinds as surface material and the batten and bamboo strip are arranged alternatively. The utility model is far more strong than common block board in strengthen and is less than bamboo glue pattern plate in density. The bamboo-wood composite block board can not only substitute the common block board to be timbering, but also is used as plywood for concrete form.

Description

Bamboo wood composite joiner's board

One, technical field

The utility model belongs to the wood-based panel product manufacturing technology in the wood working industry.

Two, background technology

Existing core-board is a kind of jigsaw or wooden frame structure of being made up of batten, and the top layer is coated with Wooden veneer.Core-board has advantages such as good stability, distortion is little, density is little, rigidity is big, is widely used in the internal structure material of furniture, platen, vehicle manufacturing, boats and ships and building industry.Along with the needs of building trade development, the consumption of concrete blinding is increasing, and simple plank sheathing, plywood form etc. can't have been satisfied the demand, and therefore, having occurred multiple is the building template product that raw material is made with the bamboo wood.The pure building template made from bamboo wood, its main deficiency is that density is too big; If directly as building template, its mechanical and physical performance can not meet the demands again with traditional core-board.

Three, summary of the invention

Purpose of design of the present utility model is, and is too big at the above-mentioned building template density made from bamboo wood purely; The present situation that traditional core-board directly can not meet the demands again as its mechanical and physical performance of building template is developed a kind of novel bamboo wood composite joiner's board product.

Technical solution of the present utility model is: form sandwich layer in the mode that bamboo chip and batten mix, as skin-material, make bamboo wood composite joiner's board with bamboo mat and bamboo curtain splint after assembly, gluing, hot pressing.This novel bamboo wood composite joiner's board product, when both having satisfied as building template to the requirement of finished product mechanical and physical performance; Compare with the building template of all making, obviously reduced the density of finished product again with bamboo wood.

Four, description of drawings

Fig. 1 is the typical structure schematic diagram of bamboo wood composite joiner's board.(1) is bamboo mat among the figure, and (2) are bamboo curtain splint; (3) be batten, (4) are bamboo chip;

Fig. 2 is the another kind of version of bamboo wood composite joiner's board, has increased layer of surface decorative layer (5), and all the other and Fig. 1 are identical.

Five, the specific embodiment

Embodiment 1:

Fast growing wood is processed into wide and high certain batten, mao bamboon is processed into the bamboo chip that width and batten height equate, thickness is about 3mm.With the batten that processes and the bamboo chip after being coated with (or soaking) glue according to the mode shown in the accompanying drawing 1, spaced composition core material.

Make bamboo mat and bamboo curtain splint after mao bamboon or other small diameter grade bamboo split the thin bamboo strip, constitute two top layers up and down respectively in interior, bamboo mat mode outside with bamboo curtain splint.

With the two-layer bamboo curtain splint gluing up and down behind the assembly, after conventional hot pressing, cooling, cutting edge, sanding, can obtain thickness is the bamboo wood composite joiner's board finished product of 12～20mm.

Embodiment 2:

Make bamboo wood composite joiner's board by the method described in the embodiment 1 earlier, and then as shown in Figure 2, one of bamboo wood composite joiner's board or up and down two surfaces cover one deck impregnated paper or other surface materials (5) again, make the higher bamboo wood composite joiner's board product of surface quality.

Intensity of the present utility model is compared with common core-board and is significantly improved; Its density then is lower than bamboo glued mould.Therefore, bamboo wood composite joiner's board not only can substitute common core-board and use as structural wood, especially is suitable as concrete blinding and uses.

Claims

1. bamboo wood composite joiner's board product of making after gluing, assembly, hot pressing is characterized in that with bamboo mat (1) and bamboo curtain splint (2) forming sandwich layer as skin-material with batten (3) and the spaced mode of bamboo chip (4).
