Description

Solid wood face offset plate composite floor board

Technical field

The utility model relates to the flooring in the building fitting-out work, particularly the floor of being made up of some similar components.

Background technology

A whole set of technology and factory that the wooden floor chip of special production flooring finishing usefulness is just arranged decades ago.Raw material timber will be earlier through air-dry when just beginning, pass through shaping again, be split into half inch thick four inches wide both sides and have the rectangular of joint tongue, tongue-and-groove, so that can be at an easy rate after the buyer buys back be embedded in each bar plank together and nail is gone up or binded on smooth cement floor at the building of wood frame (rough ground), form the full wafer timber floor.The waste of such way timber is very large, afterwards first because the supply of timber is fewer and feweri; Second because the contraction of the wooden floor chip of being made by the monoblock natural timber, distortion are too big, will be during laying because of distortion is difficult to operation, the out-of-flatness that also can become gradually of the timber floor after the laying; Three because the raising day by day of standards such as building fire prevention insect protected; So the wooden floor chip of plant produced all is multi-layer combined (floor that does not contain the solid wood surface layer fully is not in the discussion scope of present patent application) at present.For example modal in the market solid wood floor bar is formed by at least three layers: the superiors are solid wood faces, be the precious timber (for example teak) of one deck 4 millimeters thick, be the common timber (for example pine) of one deck 12 to 18 millimeters thick below or simply be the multiply-plywood of same thickness, bottom is generally the damp-proof layer (moistureproof bottom can omit sometimes when lower floor used multiply-plywood, had suffered because this damp-proof layer may be included in multiply-plywood) that polyester is made.

The advantage on multi-layer combined floor is conspicuous: at first be outward appearance and the character that surface layer still has precious timber, can stand a spot of plane, mill processing after the laying.Next is that the floor of the contraction on whole floor, deformation ratio monoblock plank is little after the assembling because used the interlayer form.The 3rd is because most material is common par timber, and totle drilling cost is descended greatly.Even so, the price of timber floor still is more than a times of ceramic tile floor at present.Therefore, the ceramic tile floor of all having to now adopt, many cities (for example Hangzhou) that are positioned to the north of the Xiamen.In order further to reduce the cost of solid wood floor, unique method is further to reduce materials, the smear metal when for example the common wood layer is made in the thickness of attenuate solid wood surface layer and minimizing; Unfortunately in prior art constructions, 4 millimeters thickness has been the limit, because the common wood (for example pine) as multi-layer combined floor lower floor does not have precious timber high mechanical strength like that, surface layer can Bei Gang Heel high-heeled shoes be stepped on less than 3 millimeters and is worn and form permanent indenture.4 millimeters solid wood surface layer is only for twice polishing processing (each polishing amount is 0.5 millimeter).

Therefore, the problem that how further to reduce solid wood composite floor integrated cost has just become the key point how the solid wood floor seeks survival with ceramic tile floor competition.

The utility model content

The purpose of this utility model provides a kind of solid wood face offset plate composite floor board, it has reduced precious timber of the prior art exponentially and has significantly reduced the use amount of common wood, owing under the solid wood surface layer, increased one deck Formica, the original mechanical strength of prior art and the number of times of polishing have again not only been kept, make production cost descend 30% again than prior art, deflection reduces greatly, and mechanical strengths such as wear-resisting, shock resistance improve greatly, infiltration chance and lay workload and reduce at double.

In order to achieve the above object, solid wood face offset plate composite floor board of the present utility model mainly is made up of following each layer: 1) traditional disposable wearing coat; 2) the multilayer precious timber layer of thickness of for once polishing; 3) the Formica layer of raising top layer mechanical strength and security; 4) common wood layer or traditional splinting layer; 5) traditional damp-proof layer; Bind with traditional splicing adhesive between each layer.

Preferably, the precious timber layer is between wearing coat and Formica layer, and the thickness of every layer of described precious timber layer is about 0.5 millimeter and bind by splicing adhesive.

Preferably, the thickness of glue plate layer is about 1 millimeter, and is arranged at the top of traditional splinting layer.

Preferably, glue plate layer is made by many brown paper.

The specific embodiment

Fig. 1 is the cross-sectional view of prior art solid wood floor bar.11 is traditional disposable wearing layers of processing in factory among the figure, and this one deck wearing and tearing back in use on the floor has just disappeared forever, can't rebuild at the scene.The solid wood surface layer of the precious timber of the 12nd, at least 4 millimeters thick (for example teak).13 is basic units of 12 millimeters common wood to 18 millimeters thick (for example pine).This one deck also can replace with the multiply-plywood of stack pile.The 14th, traditional polyester material moisture layer.When replacing the basic unit of common wood with multiply-plywood, may have damp-proof layer, so can omit sometimes because of in the clamping plate.The 15th, by layer 13 integrally formed joint tongue, the 16th, by layer 13 integrally formed tongue-and-groove.The width of this lath is 6 inches to the maximum, just has tangible deflection deformation if surpass 6 inches (for example 12 inches), has consequently just laid just to have to dig (or mill) flat processing.The polishing back is because of the disappearance of disposable wearing layer, and adding upper surface has at least 0.5 millimeter precious timber to be polished off again, therefore greatly reduces the life-span (appointment reduces by the service life in 10 years) on the contrary.The 17th, the adhesive agent each layer sticks together generally uses traditional splicing adhesive.

Fig. 2 is the cross-sectional view of the utility model solid wood face offset plate Composite floor-board bars.Adopt identical label with the part of same nature among Fig. 1: the basic unit 13 that the disposable wearing layer 11 among Fig. 2, damp-proof layer 14, binder 17 and common wood form we can say with Fig. 1 in identical.In Fig. 1 and Fig. 2, though joint tongue 15 and tongue-and-groove 16 are painted as rectangle, this just for convenience.Any in actual use tradition and/or unconventional joint tongue/tongue-and-groove can be used in the utility model.Places obviously different with Fig. 1 among Fig. 2 are:

(1) precious timber layer 12 is thinner than the layer 12 among Fig. 1 widely, and multilayer (only having drawn three layers among the figure) is arranged.

(2) newly added one deck glue plate layer 18.

The thickness of precious timber layer 12 has only 0.5 millimeter among Fig. 2, adds after 0.1 millimeter the plus tolerance also just 0.6 millimeter.This be because the combined type floor among Fig. 2 aspect gross thickness when identical with prior art floor among Fig. 1, the widely prior art floor strips of crossing among Fig. 1 (when especially replacing the basic unit 13 of common wood) of the number of plies with clamping plate more, so the deflection deformation amount also just is lower than the floor strip of prior art among Fig. 1 widely.Therefore plane, the mill amount of carrying out for smooth purpose is minimum, at every turn can be above 0.5 millimeter.Shootd off when two-layer when the precious timber layer among Fig. 2 12, also have the 3rd layer 12 playing the solid wood face, this point and prior art can dig twice identical, but used precious timber amount has only prior art half (0.6 * 3=1.8 millimeter).When practical application the utility model, layer 12 does not limit must three layers, can consider three layers of many mistakes in bigger occasions of wearing and tearing such as being used for the public place.

The precious timber layer 12 of 4 millimeters thick of prior art is attached on the low intensive common wood layer 13 among Fig. 1, when the surface of layer 12 is subjected to concentrfated load (for example Gang Heel high-heeled shoes steps on suddenly), layer 13 is very soft because of itself, can't provide support to layer 12, layer 12 must bear pressure alone, so 3 millimeters thickness will be arranged at least.And in the solid wood face offset plate composite floor board of the present utility model of Fig. 2,0.5 millimeter every layer precious timber layer 12 all has the jigsaw glue-line 17 of certain flexibility to support, has the glue plate layer 18 of 1 millimeters thick to support again on less than 2 millimeters the degree of depth.So impact resistance far surpasses layers 12 of simple 3 millimeters thick among Fig. 1 (layer 12 that is 4 millimeters of original thicknesses is through the size behind twice plane/mill).

Glue plate layer 18 among Fig. 2 is to flood back drying hot repressing by many brown paper in phenolic resins to form in about 1 to 2 hour.The solid wood face offset plate composite floor board of making of the present utility model can meet 1 grade of regulation in European construction material refractory standard BS476 the 7th part also because this one deck glue plate layer 18 is arranged when doing fire-resistant test.Because the bottom of solid wood face offset plate composite floor board of the present utility model is a colloid damp-proof layer 14, surface layer has glue plate layer 18, has reduced any moth moth and has worn that this is two-layer and enter chance in the basic unit 13, thereby had the insect protected function.

The reason that solid wood face offset plate composite floor board of the present utility model more causes deflection deformation to reduce owing to MULTILAYER COMPOSITE above-mentioned, can make 12 inches wide floor strips (prior art is made 6 inches wide at most), the benefit of large scale floor strip has been to reduce the roll line number between bar and the bar, process velocity is significantly improved, roll line has lacked the infiltration chance that makes whole floor and has reduced, mechanical strength improves (because joint tongue, the ability to bear of the ability to bear of tongue-and-groove telescoping part during) always less than one, the wear and shock-resistant raising, more attractive in appearance, reach more than 30% thereby reduce integrated cost.
