Abstract

The utility model relates to a bamboo (wood) composite high strength door panel for building houses, which is characterized in that dispersed bamboo splits (or bamboo shades), crushed aggregates, bamboo mats, wood veneers and synthetic resin are assembled into proximate matter according to a figure, and the utility model is formed by one-time hot pressing with a definite special process. The joint positions are altered from tenon joint into glue joint, which can omit sawmilling, planing, tenoning, etc., working procedures. The door panel has the advantages of good water resistance, good wearing resistance, good flame retardation, high strength, light weight, low cost, and easy manufacture. The utility model can save large amounts of timber resource by using the bamboo to replace the wood.

Description

Bamboo (wood) composite high strength door leave

The utility model relates to bamboo (wood) the composite high-strength door-plate that a kind of building construction is used.

Building construction is generally the wood materials manufacturing with door-plate, and China is a country that lacks timber resources, but bamboo timber resource is very abundant.Wooden door-plate is corrosion resistant not too generally, is easily damaged by worms, and intensity is not too high, tenon position particularly, and intensity is lower.

The purpose of this utility model is to provide a kind of bamboo (wood) composite high-strength door-plate.

The technical solution of the utility model is bamboo timber resource and the great amount of manpower resource that is to utilize China's abundant, and will loose thin bamboo strips used for weaving (or bamboo curtain splint) and particle, bamboo mat, veneer and synthetic resin through certain special process, are produced the high strength door-plate; Joint area changes joggle for glueing joint.Its concrete structure is referring to accompanying drawing: the framework that frame is made up of loose thin bamboo strips used for weaving or bamboo curtain splint around the door-plate, or the long limit in the frame is a flitch, frame mid portion has diffusing thin bamboo strips used for weaving (or bamboo curtain splint) horizontal stroke side (1), the interlaced overlap joint glue of lap-joint of the lap-joint in length and breadth of frame and horizontal stroke side (1) and frame longitudinal edge solid (shown in Figure 2).Framework two surface courses set gradually bamboo mat (3) (or bamboo curtain splint) and veneer (2); The framework sandwich layer is a particle (4) (shown in Figure 3).

Production technology of the present utility model is that synthetic resin will loose thin bamboo strips used for weaving (or bamboo curtain splint), bamboo mat, veneer and particle according to the structure chart assembly, and through certain technology, a hot pressing forms.The junction in length and breadth that requires frame and horizontal stroke side during assembly respectively overlaps with 1/2 diffusing thin bamboo strips used for weaving (or bamboo curtain splint) quantity, should select the temperature that adapts with it for use according to used glue kind during hot pressing, if then should carry out hot pressing at 120 ± 5 ℃ with Lauxite, if then should carry out hot pressing at 140 ± 5 ℃ with phenolic resins, time and pressure are then decided on thickness of slab and density.

In sum, bamboo (wood) composite high-strength door-plate and common wooden door-plate have relatively saved sawmilling, planing, operations such as mortise, and production technology is simple, and cost is low; Whole door-plate is that a gummed is whole, face shaping is consistent with the normal wood scutum, but surface aesthetic does not have joggle, joint area changes joggle for glueing joint, the synthetic resin itself that uses has sterilization and water-fast and fire resistance, so this door-plate is water-fast, corrosion resistant, fire resistance are good, the intensity extra-high-speed, in light weight, make easily, particularly wood substituted by bamboo has been saved a large amount of timber resources.
