Abstract

The utility model relates to a structural floorboard with a core plate formed by HDF, which aims to provide a structural floorboard with a core plate formed by the HDF which has low prices, convenient manufacture, less log-consumption, beautiful appearance and good quality. The structural floorboard sequentially comprises an uppermost surface plate, a core plate and a base plate from topside to bottom, wherein all plates are mutually glued to form floorboard blanks via adhesive substances. Besides, matchboards mutually spliced are arranged on lateral surfaces of the floorboard blanks, the core plate is formed by with-grain wood boards between two HDF plates, and at least one layer of the wood boards has the same wood fiber direction with that of the surface plate. The utility model has the advantages that the floorboard essentially maintains service performance of original solid wooden compound floorboards, the core plate employs the with-grain wood boards, thereby enabling the whole floorboard to have better rigidity in length direction and preventing wood fibers from being split, peeled and burred, and having tongued-and-grooved deformation during the process of cutting edges and slotting. In addition, mutually splicing quality of floorboards is excellent, and splicing strength is high. Further, utilization of the HDF plates has a positive effect on improving wood utilization ratio and protecting forest resources and ecological environment.

Description

Central layer is the structure floor of HDF

Technical field

The utility model relates to a kind of wood flooring, the structure floor that particularly a kind of central layer is HDF.

Background technology

The wood flooring of selling on the market is wooden floor, solid wooden compound floor mostly now, wooden floor is owing to will consume the log of a large amount of complete high-qualitys, timber utilization rate is low and price is higher, and solid wooden compound floor can be according to the function of using, at the surperficial bonding top grade on floor, the thin slice timber of hard rigid material, can use the timber of general material down below, science, economy are compared in such floor on material.But also be to use a certain amount of log after all, and because the difference of material, their linear expansion coefficient and internal stress are also different under different temperature, therefore after finishing, the composite floor board manufacturing also can deform, and general composite floor board has 0.8-1.5 rice long, and therefore the distortion meeting of accumulation stack is very big, makes the floor that warpage take place, even dash board and base plate produce and come unstuck and separate, and influences attractive in appearance and functional performance.

The utility model content

The utility model has overcome the shortcoming that exists in the existing product, provide a kind of cheap, easily manufactured, use that log is few, good looking appearance, the measured central layer of matter be the structure floor of HDF.

In order to reach above-mentioned requirements, the utility model is achieved through the following technical solutions: it comprises uppermost dash board, be downwards central layer, base plate successively, each plate is each other through adhesive glue composition floor blank, be shaped on the tongue and groove of mutual splicing in the side of floor blank, it is characterized in that described central layer is made up of the plank that accompanies at least one layer of direction of wooden fibers forward texture identical with the direction of wooden fibers of dash board in the middle of two HDF plates.

The HDF plate is the abbreviation of high density fiberboard, and it is that timber or string are separated and chemical means is handled through machinery, with adhesive with (or) additive, a kind of artificial board of making through high temperature, high-pressure molding again.Have material evenly, advantage such as intensity difference is little, not easy to crack in length and breadth, price is low.Central layer according to the such scheme manufacturing is the structure floor of HDF, substantially the functional performance that has kept original solid wooden compound floor, good looking appearance, central layer adopts the forward plank of texture, make the monoblock floor the rigidity of length direction better (general floor is identical with the direction of wooden fibers of dash board at length direction), can not take place in cutting edge, fluting that wood fiber is torn, peeled off, the phenomenon of burr, tongue and groove distortion, the mutual joining quality in floor is good, intensity is high.Use the HDF plate to the utilization rate that improves timber, protect forest resources and ecological environment plays a positive role.

Description of drawings

Fig. 1 is that central layer is the structure floor front view of HDF;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the A-A cutaway view Amplified image of Fig. 1.

Wherein: 1, dash board; 2, central layer; 3, base plate; 4, tongue and groove; 5, HDF plate; 6, plank.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

As seen from the figure, it comprises uppermost dash board 1, is downwards central layer 2, base plate 3 successively, and each plate is shaped on the tongue and groove 4 of mutual splicing each other through adhesive glue composition floor blank in the side of floor blank.Wherein the thickness of dash board 1 0.2 millimeter and more than, as 0.25 millimeter, 0.3 millimeter, 0.4 millimeter etc., be to make by the famous and precious seeds of high-quality such as the high-quality timber of walnut or teak or maple or cherry etc.Central layer 2 is to be formed by plank 6 gummeds that accompany one deck or the two-layer direction of wooden fibers forward texture identical with the direction of wooden fibers of dash board 1 in the middle of two HDF plates 5.The thickness of HDF plate 5 generally 2 to 8 millimeters also can be more than 8 millimeters, as 3 millimeters, 4 millimeters, 5 millimeters, 10 millimeters etc.Upper surface at dash board 1 scribbles paint as requested.

Claims

1, central layer is the structure floor of HDF, it comprises uppermost dash board, be downwards central layer, base plate successively, each plate is each other through adhesive glue composition floor blank, be shaped on the tongue and groove of mutual splicing in the side of floor blank, it is characterized in that described central layer is made up of the plank that accompanies at least one layer of direction of wooden fibers forward texture identical with the direction of wooden fibers of dash board in the middle of two HDF plates.

2, central layer according to claim 1 is the structure floor of HDF, it is characterized in that described plank has one deck or two-layer gummed to form.
