Abstract

The utility model discloses a laminated solid wood door sash. Three layers or more than three layers of solid wood plank stuffs are arranged in a staggering and laminating way in turn according to the longitudinal grain plank stuffs and transverse grain plank stuffs; each layer of plank stuffs are coated with glue to form a stock and then are shaped by heat pressing. In the utility model, the solid wood plank stuffs are arranged in a staggering and laminating way in turn according to the longitudinal grain plank stuffs and transverse grain plank stuffs, thus being beneficial to overcoming the anisotropy of expansion and contraction deformation of the self of the wood and greatly reducing the deformation of a door sash caused by the anisotropy of the wood; the directions of the grains between layers are arranged in a staggering way and are mutually hampered which can basically stop the phenomenon of cracking of the door sash during the use process from happening; simultaneously the physical performances of the intensity, the mechanical processing performance and the nail-holding ability of the wood door sash are improved to a large extent.

Description

A kind of laminated type solid wood door leaf

Technical field

The utility model relates to the structure of the structure and the manufacturing thereof, particularly solid wood door leaf of wooden door leaf.

Background technology

In recent years, in house decoration, can't help the carpenter master worker substantially and make wooden door leaf at the scene by hand, but on-the-spot the installation by the timber manufacturing enterprise of specialty with the good solid wood door leaf of machining, this solid wood door leaf has on door face board to be made or has carved various different decorative designs and painted paint, the various different decorative designs of making or engraving on door face board is only also arranged and the timber base of not painting.Preparation method and structure that this solid wood door leaf is commonly used are: with iron nail (using nailing) or chase mortise the lumps of wood that processes is connected into timber framework 6 earlier more, and four jiaos of region of interest with installation door hinge and door lock of opposite house are suitably reinforced with wooden boss 7 and wooden reinforcing rib 8, insert cellular board or paling bar etc. as casting resin 9 at the position, space that does not have the lumps of wood and wooden reinforcing rib (piece) again, then on the front and back of timber is gluing artificial decoration plate etc. as timber surface material 10, after cold pressing or hot-formingly be solid wood door leaf (as Fig. 2).But, the solid wood door leaf of this structure ubiquity door leaf in processing and use is out of shape and the problem of cracking is difficult to overcome, main cause is a different cities, the climate difference of different regions causes airborne equilibrium moisture content difference, so wet deformation extent difference that rises of the drying shrinkage of timber, wet the rising of the drying shrinkage of timber self has anisotropy in addition, it is radially inequality with the wet deformation extent that rises of tangential drying shrinkage, therefore along with the door leaf prolongation of service time, solid wood door leaf tends to occur distortion, cause door leaf to close and do not live or fit badly, influence is normally used, and also may cause the door leaf cracking, destroy the enamelled coating of door leaf surface, influence attractive in appearance.In addition, the solid wood door leaf of this tower structure connects by nailing or chase mortise, be difficult to guarantee its intensity in the machine-shaping process, so also there is not impact-resistant problem in the finished product door.

The utility model content

Goal of the invention of the present utility model is easy deformation, cracking and the insufficient strength that overcomes the solid wood door leaf existence of above-mentioned prior art, not impact-resistant problem, design a kind of laminated type solid wood door leaf that is overrided to form by the solid wood board more than three layers or three layers, reduce solid wood door leaf distortion and cracking phenomena in use greatly, and improve its impact strength.

For realizing that the technical scheme that the object of the invention adopts is: multi-layer solid wood sheet material is arranged by slash grain sheet material and horizontal wood-grain plate cross laminates successively, on the contact surface of each piece sheet material, be coated with bonded adhesives again and carry out assembly, adopt the lamination of making artificial veneer hot-forming then.

When the utility model was the three-layer real-wood door leaf, door face board and door backboard two-ply timber line direction were vertically, and middle central layer sheet material grain direction is laterally.If door face board and door backboard two-ply timber line are that laterally then Zhong Jian central layer sheet material wood grain is for vertically also can.

Can carve on the door face board of the utility model solid wood door leaf or bonding various decorative pattern, and paint paint.

The utility model has the advantages that solid wood board by slash grain sheet material and laterally wood-grain plate cross laminates arrangement successively, hot-forming, help overcoming the anisotropy of the wet distortion of rising of timber self drying shrinkage, the wooden door leaf distortion that is caused by anisotropy of wood is greatly reduced; The interlayer grain direction is staggered, and pins down mutually, can stop the generation of cracking phenomena in the wooden door leaf use basically; In addition, physical properties such as the intensity of wooden door leaf, machining property, nail-holding ability also are greatly improved.

Description of drawings

Fig. 1 is of the present utility model three stacked laminar solid wood door leaf partial structurtes schematic diagrames;

Fig. 2 is the frame type wooden door leaf structural representation of prior art.

The specific embodiment

With three layers laminated type solid wood door leaf of a fan as embodiment of the present utility model, as shown in Figure 1.Wooden door leaf panel 1 adopts grain direction to be solid wood board longitudinally, wooden door leaf backboard 2 also adopts grain direction to be solid wood board longitudinally, 3 employings of the central layer grain direction that is clipped between door face board 1 and the door backboard 2 is horizontal solid wood board, between door face board 1 and central layer 3, and coat layer of adhesive material 4 and 5 between door backboard 2 and the central layer 3, place hot press hot-forming the above-mentioned three-layer real-wood door leaf blank that connects with adhesives, just made of the present utility model three stacked laminar solid wood door leafs.As required can be on door face board 1 bonding or carve out various decorative pattern, can also paint paint again, become a kind of top grade, solid wood door leaf attractive in appearance.

Characteristics according to timber, or make full use of the needs of material, the utility model can be made into the multilayer laminated formula solid wood door leaf more than three layers, but each layer solid wood board must by grain direction for vertically and grain direction for laterally being staggered successively, such as four layers of door leaf of a fan, the door face board grain direction is vertical, the central layer grain direction of being close to panel should be horizontal, another piece central layer grain direction then should be vertical, the grain direction of door backboard is horizontal just, between each laminate material, coat adhesives then and form door blank, hot repressing moulding.
