Abstract

The utility model relates to a composite wood floor. The composite wood floor is characterized in that a plurality of longitudinal slots are arranged on both surfaces of a median plate. The depth of the slot is 50 percent-80 percent of the thickness of the median plate. Two skin plates are arranged on the upper part of the median plate, and two base plates are arranged on the lower part of the median plate. Both surfaces of the median plate of the utility model are provided with crisscross slots, and the fibre in the plate can be cut off moderately. Skin plates and base plates are bonded on the upper side and the lower side, which provides a stable function to the entire plate. The variation of stresses in the plate which is caused by the humidity and dryness of the environment is reduced. The plate is not easy to bend. Furthermore, the utility model has a simply manufacture procedure and a less wastage, and the manufacture cost is decreased greatly.

Description

A kind of combined type wooden floor

Technical field:

The utility model relates to the technical field on floor, specifically a kind of wooden floor of combined type.

Background technology:

Wooden floor in the market mainly is divided into two kinds, a kind of employing two is to three layer construction, ground is two-layer, every layer thickness is 8-10mm, thickness is placed in the middle, can't cooperate with existing raw material, must make specially, and such thickness can't adopt the processing method of the saving timber of rotary-cut or slicing etc., can only take saw, processing methods such as plane also will be drawn groove simultaneously, mill circular groove, whole process makes the sheet material loss up to about 45%, the only remaining 11mm in sheet material processing back that just 20mm is thick so just do not reach the purpose of saving timber, and the sheet material of thickness makes very difficulty of processing like this, production efficiency descends, and cost raises; Another kind of solid wooden compound floor, adopt the solid wood skin of rotary-cut, press the grain direction of timber, crisscrossly put stack, after being accumulated to certain thickness plate behind the repeated multiple times heat pressure adhesive, on a surface of this plate, post one deck senior plane materiel different again than the minimal thickness material, this kind floor can adapt to multiple dried wet environment, the probability of distortion is lower, but manufacturing procedure is many especially, substantially all about 18mm, this thickness has been subjected to the approval in market to the wooden floor thickness that existing market is sold, and in this composite floor board as reaching 18mm thickness, be subjected to the influence of machining intensity because of rotary-cut solid wood skin, peeling thickness generally is no more than 1.7mm, must be through 10-15 time gluing repeatedly, hot pressing so just makes cost significantly promote, wasted the energy, and so the delta wood skin superposes in length and breadth, and is coarse especially around the plate, influence the attractive in appearance and texture of shortage solid wood in floor.

Summary of the invention:

The purpose of this utility model is to provide a kind of improved combined type wooden floor, and it can overcome the easy flexural deformation in floor in the prior art, and the big some shortcomings of loss.

To achieve these goals, the technical solution of the utility model is: a kind of combined type wooden floor, it mainly comprise panel, base plate and be located at panel and base plate between middle plate, it is characterized in that: the two sides of middle plate is equipped with some grooves longitudinally, the degree of depth of groove is the 50%-80% of sheet metal thickness, middle plate is provided with two-layer panel, and middle plate has two-layer base plate.

The sheet material two sides is equipped with crisscross groove in of the present utility model, fiber in the solid wood plate can be given blocking of appropriateness, again at middle plate top and bottom glue panel and base plate, whole sheet material has been played stable effect, reduced because of external environment humidity and mass dryness fraction change the solid wood intralamellar part STRESS VARIATION that is caused, plate is difficult for flexural deformation, and production process of the present utility model is simpler, loss is less, greatly reduces cost of manufacture.

The specific embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprise panel 1, base plate 2 and be located at panel and base plate between middle plate 3, its difference with the prior art is: the two sides of middle plate is equipped with some the longitudinal grooves that are parallel to each other 4, in concrete enforcement, groove is generally the 2-25 bar, the degree of depth of groove is the 50%-80% of sheet metal thickness, middle plate is provided with two-layer panel, and middle plate has two-layer base plate; Two-layer panel is formed by a longitudinal plate 5 and horizontal sheet material 6 heat pressure adhesives, and two-layer base plate is formed by horizontal sheet material 7 and a longitudinal plate 8 heat pressure adhesives; The two sides of middle plate is equipped with the traverse furrow groove 9 perpendicular with the longitudinal furrow groove, and the traverse furrow groove also is parallel to each other, and its degree of depth is the 20%-60% of sheet metal thickness; The longitudinal furrow groove of middle plate one side and another side longitudinal furrow groove are staggered alternate, and the traverse furrow groove of middle plate one side and the traverse furrow groove of middle plate another side are staggered alternate; One group of middle plate intersects the side and is provided with groove 10, be provided with and the corresponding raised line 11 of groove on the crossing side of another group of middle plate, plate is just aimed at the corresponding groove of plate in another piece to the raised line of middle plate one side when assembly unit, just install after the engaging, convenient and practical.

In force, the longitudinal plate of the superiors can adopt thinner thickness or the different plane materiel of material in the panel, normally used is higher sheet material, and remaining sheet material just can use price lower, the timber faster of growing up, the processing method of rotary-cut of these sheet materials utilizing usually obtains thin sheet material, again with horizontal sheet material and sheet material longitudinally by the superimposed two-layer panel that becomes of heat pressure adhesive, simultaneously also sheet material and horizontal sheet material become two-layer base plate by heat pressure adhesive is superimposed longitudinally, draw staggered in length and breadth groove then on the two sides of middle plate, this groove has blocked the texture of sheet material, when plank is subjected to the influence of outside humidity and when producing plate and changing, these stress just can be in plate inside get by these grooves and digest, horizontal sheet material in panel and the base plate has played horizontal stabilization to whole floor simultaneously, longitudinal plate in panel and the base plate has played stabilization longitudinally to whole floor, thereby make the surface of sheet material flexural deformation or crack can not occur, work as panel, middle plate, after the bottom processes, only need panel with adhesive, middle plate, base plate is bonded together and gets final product, and is simple to operation.
