Description

Composite panel

The utility model relates to a kind of accessory of building, particularly door.

Crackle, distortion etc. easily take place because of the intrinsic natural quality of timber in the flat timber of opening traditional in building field.Though plywood door is saved timber, attractive in appearance than the flat timber of opening, not firm, user does not have the sense of security.Utility model patent communique (on August 31st, 1988) disclose a kind of＜subsides sheet metal door〉(CN87215269U) its purpose provide a kind of sturdy and durable, fire prevention, antitheft, the non-wooden door of saving timber, its formation is to constitute the surrounding by double layer of metal door-plate and stiffener welding to connect, use paper curtain or honeycomb paper, its whole connection of the bonding formation of wallpaper between the double layer of metal door-plate, though its weak point is the door saving timber of this structure but need uses steel, and it is narrower self to weigh range of application.

In view of being to provide a kind of, above-mentioned weak point the purpose of this utility model of the prior art replaces high-quality timber with non-dimension timber, and from heavy and light, firm, insulation, combined type plate door attractive in appearance.

The purpose of this utility model can reach by following measure: a kind of combined type plate door that is used on the building, it mainly is made up of two-layer door-plate and its inner attachment, it is characterized in that being fixed with on the wood frame inner rim honeycombed wood pulp corrugated paper of opening towards both sides, its both sides all are fixed with the veneer door-plate of surface attachment facing.The used veneer of door-plate is to wait outer veneer.On slicing wood facing, has 196# unsaturated polyester resin coating.

The assembly that the utility model is made up of the material of different structure and material.The utility model periphery is provided with the framework that increases rigidity.This framework is wooden, can adopt various timber.For save timber reduce cost preferably utilize the plywood factory pay product such as linden, its raw material sources are extensive, have viscose glue preferably, use securing member such as screw that embrittlement deformation does not take place, both are in conjunction with advantage such as firm.This framework is according to the shape of door and size passes through to make tenon or metal connecting piece is made up of four flitches.Be preferably in and establish door lock, hinge or handle etc. and need establish on the position of connector the reinforcement plank that is connected as a single entity with this framework is set, be securely fixed on the plate door to guarantee door lock, hinge and handle etc.Be provided with honeycombed wood pulp corrugated paper in the wood frame, be fastened on the wood frame inner rim around it.The honeycomb opening preferably is bonded on the framework by cementing agent such as urea-formaldehyde glue and forms an integral body with framework towards both sides, so that connect the both sides door-plate.The door-plate of framework and corrugated paper both sides is a veneer.Can be for saving timber with plywood factory's waste material through cementing agent such as Lauxite glue bond, can obtain cheap not water funk, have plasticity, stable performance etc. outer veneer.The framework ， And that is provided with corrugated paper with its covering fixes it with securing member or cementing agent.Preferably every side honeycombed opening all scribbles cementing agent, can form integral planar with the veneer bonding together and be connected, and makes framework, corrugated paper veneer three form an integral body, increases its plane stiffness.Can have facing such as various slicing wood, facing paper or plastics etc. in the outside of veneer for the surface of modified product, the door-plate surface is handled.It is fixed on the face veneer, preferably adopts cementing agent bonding.On the decorative panel surface preferably again with one deck cover, as the 196# unsaturated polyester resin, it not only gains in strength, anticorrosion, back-fire relief, outward appearance is good and its surperficial can be never oily with brush.

Drawing is described as follows:

Fig. 1 is a front elevational schematic of the present utility model.

Fig. 2 is the local enlarged diagram of A-A among Fig. 1.

The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the schematic diagram of combined type plate door illustrated in figures 1 and 2, four linden square end portion joggles through giving handling constitute the framework 1 of a door.Neighboring at framework is adhesive with linden joint strip 2 again.The reinforcement plank 3 that is connected as a single entity with this framework is set on the position of establishing door lock, hinge and handle.Make honeycombed wood pulp corrugated paper 4 with 130 gram wood pulp corrugated papers., its surrounding is bonded on the framework inner rim with urea-formaldehyde glue.The honeycomb opening is towards both sides, and above it and framework both sides all scribble urea-formaldehyde resin adhesive, bonds together with the veneer door-plate 5 that covers in the above.This veneer door-plate is to use the three layer veneer of the waste material of veneer through the Lauxite glue bond.In above-mentioned veneer door-plate outside with the fixing slicing wood 6 of one deck Albizzia kalkora or Manchurian ash of resin glue.Be coated with last layer 196# unsaturated polyester resin at last again on its surface as cover, can obtain the finished product of combined type plate door.

The utility model has following advantage compared to existing technology: 1. than existing flat timber intensity height, the crackle, sturdy and durable not opened, fire prevention, antitheft, from heavy and light, angle is even, attractive in appearance, sound insulation, insulation. 2. utilize the utilization rate of waste wood raising timber, lower than high-quality timber, the cost of common door saving 70%. 3. adopt the composite plate of this structure can also make various furnitures.
