Description

A kind of three-layer wood composite flooring

Technical field

The utility model relates to a kind of solid wooden compound floor, belong to floorboards of wood technical field.

Background technology

In prior art, the sandwich layer of the composition of solid wooden compound floor in the middle of mainly comprising, and upper and lower composite bed forms, and how many according to the number of plies of composite bed, forms the multi-layer composite floors such as three layers, four layers or five layers; Existing the simplest composite floor board is three-layer wood composite flooring, the key of this solid wooden compound floor is sandwich layer, the sandwich layer that existing solid wooden compound floor is selected mainly comprises the middle density central layer that coefficient of deformation is low, or the wooden central layer being arranged at an angle of 90 in machine direction with upper and lower composite layered plate etc.But above-mentioned three-layer wood composite flooring is in use, still can be subject to because of floor the impact of environment for use, the different deformation between intermediate core layer and upper and lower composite bed occurs, and then generation bulk deformation, warpage, and plate such as splits at the phenomenon.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, and easy to use, counter-bending ability is strong, the three-layer wood composite flooring of not yielding, low cost of manufacture.

The purpose of this utility model completes by following technical solution, described three-layer wood composite flooring, it mainly by solid wood surface layer, solid wood bottom and intermediate core layer by bonding compound composition each other, described sandwich layer connects bar by two length of arranging along floor length direction and is laterally connected on mutually successively the many solid wood horizontal lamellaes that described length connects between bar and forms, described solid wood surface layer and solid wood bottom are compounded in respectively the upper and lower surface of sandwich layer by cementing agent, length wherein connects in the side of the floor width edge of bar between solid wood surface layer and solid wood bottom.

Described solid wood horizontal lamellae is the irregular batten ends made from waste wood sheet material, and many solid wood horizontal lamellaes are connected on mutually successively two long connecing and between bar, form the square central layer of a block length.

The utility model, by the sticker in length and breadth of solid-wood panels and solid wood base plate and middle central layer, can make to form the layer structure mutually pining down between upper and lower flaggy, the warpage that can avoid plate to produce because of deformation, distortion and cracking; Because middle central layer is mainly joined and forms successively by polylith short slab material, therefore this plate source is abundant, can select some scoots, reduced the cost of raw material, therefore, the utlity model has simple in structure, easy to use, counter-bending ability is strong, the feature such as not yielding, low cost of manufacture.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of intermediate core layer described in the utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, three-layer wood composite flooring described in the utility model, it is mainly by solid wood surface layer 1, solid wood bottom 2 and intermediate core layer 3 are by bonding compound composition each other, described sandwich layer 3 connects bar 31 by two length of arranging along floor length direction and is laterally connected on mutually successively the many solid wood horizontal lamellaes 32 that described length connects between bar and forms, described solid wood surface layer 1 and solid wood bottom 2 are compounded in respectively the upper and lower surface of sandwich layer 3 by cementing agent, length wherein connects in the side of the floor width edge of bar 31 between solid wood surface layer 1 and solid wood bottom 2.

Described solid wood horizontal lamellae 32 is irregular batten endses made from waste wood sheet material, and many solid wood horizontal lamellaes 32 are connected on mutually successively two long connecing between bar 31 and form the square central layer of a block length as intermediate core layer 3.

Sandwich layer described in the utility model is made as follows: it is selected and solid wood surface layer and solid wood bottom solid wood blank of the same race, first make two rectangular, with solid-wood panels and solid wood base plate with long surrounding edge plate, between described two blocks of surrounding edge plates, stacked from level to level plank and overlay after glue laminated be dried to one; Then along surrounding edge plate length direction layer, be cut into blocks of sandwich layer 3; The both sides of this sandwich layer 3 are that the length that surrounding edge plate is cut into connects bar 31, the middle polylith being cut into for the plank stacking the from level to level solid wood horizontal lamellae 32 that joins successively;

The utility model cementing agent used can be carbimide aldehyde-free cement, can be also the composite floor board making cementing agent of existing routine.
