Description

A kind of composite board and composite floor board

The utility model relates to a kind of composite material for decoration and composite wood, real bamboo floor.

Existing dalle mainly contains wooden plywood, particieboard, middle and higher density fiberboard and artificial thick china thereof, bamboo rotary-cut thick china etc.Because these dalles are moisture resistance to wear no resistance, can only be used for wall decoration and furniture and make, can not be used to manufacture flooring products.Promptly be used in wall decoration, also require metope necessary dry thorough, indoor air humidity can not be too high, goes mouldy otherwise can produce equally.The flooring ornament materials mainly contains tile floor, solid wooden floor board and real bamboo floor now.Tile floor is moisture resistance not to go mouldy, and does not wet and stretches the drying shrinkage phenomenon, and easy for installation, the interior space height that takies is little, but its quality is stiff, easily breaks, and does not have " breathing " function, makes the people lack comfort, meet the air humidity height, the surface area water humidity is skidded, and particularly makes winter the people feel the there is a nip in the air.Solid wooden floor board and real bamboo floor, nature attractive in appearance, cool in summer and warm in winter, make the people that a kind of comfortable sensation be arranged, but not moisture resistance, yielding arch camber is easily gone mouldy and is damaged by worms, if directly be attached on the cement flooring, situation is even more serious.Generally all the keel frame to be set when bamboo-wood floor being installed, make floor and ground separate 2～3cm in the bottom on floor in south.However, can not overcome above shortcoming too, the dry and weather cold of air ftractures in the same old way, as if there was dampness in the air, temperature is higher, particularly fits up the arch camber of in the same old way going mouldy of newly-built building.Be again, the bottom surface, floor is unsettled, forms one and helps the subenvironment that moth grows, easier damaging by worms.This is the insoluble technical problem that is determined by material behavior.For this reason, a lot of scientific workers endeavour tackling key problem, seek feasible technical solution, as the patent No. be 96216193.4 floor and curved, set about from changing shape of floor, reduce the length of wood fibre, prevent the distortion on floor, obtained satisfied effect, be described as " international initiative; captured the difficult problem in the world, had international most advanced level ", but this is to be cost with the loss that increases timber, it is compared with the straight flange floor with width, will consume the timber about 1/3 that disappears more, go mouldy and timber floor is ubiquitous, the problem of damaging by worms does not still solve.No matter be floor and curved now, logical is the straight flange bamboo-wood floor, except having problem such as be out of shape, go mouldy, damage by worms, also has three common problems: the one, and serious waste high-quality timber and bamboo wood.Existing bamboo-wood floor is in order to guarantee enough bending strengths, the thickness of timber floor generally will be more than 20mm, the thickness on bamboo floor is at least 15mm, and the ground plate thickness 2/3 only play stressed effect, there is 1/3 thickness just to play wear allowance and decoration function at most, because the material on production floor is first-class bamboo wood, therefore have at least 2/3 high-quality timber and bamboo wood not have the excellent usefulness of excellent material, thereby 1 square metre of floor of every production to consume 4 of the high-quality bamboos that 0.05 cubic metre on high-quality log maybe will consume chest measurement 33cm.Install in addition and will use the keel frame, the wooden a tree, used in making timber for boats 3m of every square metre of needs 2 * 4cm.Therefore, consumable quantity is surprising.The timber of production timber floor is generally the broad-leaf forest trees with the ability to control oneself effect of fine water source, and these trees overwhelming majority are wildwood, and its growth period is long, just can become a useful person in general 30～50 years, and ruin it one day, is difficult to recover, and is unfavorable for ecological environmental protection.Though bamboo is a fast growing wood, can become a useful person in 3～5 years, suitably felling can not cause vegetation deterioration yet, and resource-constrained is produced the bamboo floor now, and its utilization rate of bamboo is less than 30%, and a large amount of resources are wasted; The 2nd, reduced the head room in room.Because when installing, use the keel frame that 2cm is thick at least, plate thickness also is 2cm in addition, compare with the porcelain floor like this, taken the above room head room of 3cm more, not only caused very big waste, and influence the result of use in room, cause to the people and constrain and uncomfortable sensation; The 3rd, influence floor strength, cause dry sound pollution.Because installation keel frame is wanted electricity consumption to be drilled in and is beaten many holes on the floor, sometimes the reinforcing bar of prefabricated board is all bored disconnectedly, reduce the intensity of cement floor greatly, cause potential safety hazard easily, and the electric drill perforating has serious dry sound pollution, do under the upstairs house, the neighbours is much troubled; The 4th, mounting cost height, 30 yuan～50 yuan of every square metre bamboo-wood floor installation fees; The 5th, maintain and replace inconvenience, existing bamboo-wood floor all is provided with the negative and positive groove in order to reduce the wet influence of rising of drying shrinkage on the every plank, and cover is one during installation, forms an integral body, change wherein one, is not the part nothing the matter, unless it is a sheet of not stint damage; The 7th, the production cost height.The nearly 200 yuan/m of the sale price on bamboo floor strictly according to the facts ², also incompatible with general low-income earner's the level of consumption.

One of the purpose of this utility model is to disclose a kind ofly can save high-quality timber and high-quality bamboo wood in a large number, have solid wood plate and real bamboo clappers characteristic again, resistance to compression, do cut, bending resistance, impact resistance be better than existing wooden plywood, particieboard, middle and higher density fiberboard greatly, solid wood plate, real bamboo clappers, and have wear-resisting, moisture resistance, corrosion-resistant, be difficult for damaging by worms the broad-spectrum composite board of making the floor that particularly can be directly used in of comprehensive excellent properties such as not yielding grade; Two of utility model purpose is to disclose a kind ofly can save high-quality timber and high-quality bamboo wood in a large number, keep solid wooden floor board and real bamboo floor good characteristic again, it is moisture resistance, corrosion-resistant, anti-insect, non-deformability is much higher than solid wooden floor board and the real bamboo composite floor board floor, low production cost again, perhaps also have install simple, can the directly glued composite floor board that influences advantages such as house head room hardly on the cement flooring.

The technical solution of the utility model composite board is: a kind of composite board is made up of bottom, the surface layer that is located on the bottom, and its special character is that bottom makes with bamboo plywood, and surface layer is spliced by some solid wood plates or some real bamboo chips.

The technical solution of the utility model composite floor board is: a kind of composite floor board, its special character be by the bottom made from bamboo plywood, and the surface layer that is combined into by solid wood plate or real bamboo chip that is glued on the bottom is formed.
