Abstract

The embodiment of the utility model discloses a compound floor. A wood-plastic core plate is arranged between a solid wood panel and a wood bottom plate; and the wood bottom plate is a single-layer solid wood plate or a compound wood plate consisting of more than two layers. Due to the adoption of the compound floor, stress coming from different directions can be eliminated effectively by using two layers of wood-plastic plates of which the wood grains are in different directions, full counteraction of stress can be realized, a better stress eliminating effect is achieved, an opened stress groove contributes to eliminating stress along a horizontal direction, a wood plate is prevented from arching, and the service life is prolonged.

Description

A kind of composite floor board

Technical field

The utility model relates to the floor and makes the field, relates in particular to a kind of composite floor board of multilayer.

Background technology

Wood floors are very extensive in the application of house fitting-up, and traditional wooden floor woodiness touch is good, attractive and durable, but need expend sky high cost; Take a large amount of high-quality timber resources; The Wood-plastic floor cost that utilizes plastics, wood fibre chip to process is lower, and waterproof is mothproof, can save a large amount of high-quality timber; But woodiness touch does not have wood floors good, has big not enough in appearance yet.The advantage that how to combine Wood-plastic floor and wood floors is researched and developed a kind of result of use that wooden floor can be arranged, and the novel composite floor that can reduce cost again is the problem that those skilled in the art constantly explore.

In addition; No matter be the composite floor board that traditional wooden floor, Wood-plastic floor or Wood-plastic material combines solid wood material, all can be after installing in the face of the problem of a stress, because the principle of expanding with heat and contract with cold; Can be between adjacent floor owing to expand or contraction generation stress; Especially the extruding of horizontal direction upper stress is easy to let the floor arch upward, and therefore, the stress problem that how to overcome the ground intralamellar part also is the problem that those skilled in the art constantly explore.

The utility model content

The utility model embodiment technical problem to be solved is, a kind of composite floor board is provided.Can eliminate floor stress, prolong floor application life, comprise solid-wood panels and wooden base plate, be provided with wood between described solid-wood panels and the wooden base plate and mould central layer, described wooden base plate is individual layer solid wood plate or composite wood board more than two layers.

Described solid-wood panels intersects with wood grain lines between said wooden each layer of base plate each other.

Preferable, the mutual cross angle of wood grain lines between described solid-wood panels and said wooden each layer of base plate is 60 ° ~ 120 °.

Preferably, said wood is moulded the central layer upper surface and/or soffit offers the stress groove.

Preferable, said stress slot cross-section is a triangle.

Preferable, said stress slot cross-section is a rectangle.

Preferable, said stress slot cross-section can also be semicircle.

Described solid-wood panels and said wood are moulded between the central layer and said wood is moulded between central layer and the said wood floors and is respectively arranged with adhesive phase.

Implement the utility model embodiment, have following beneficial effect:

Implement the utility model; Two-layer wood grain is moved towards different wood and is moulded plate and can effectively eliminate the stress from different directions; Can realize comprehensive counteracting of counter stress, reach the effect that more eliminates stress, the stress groove of offering more helps the stress of elimination of level direction; Preventing that plank is stressed arches upward, and increases the service life.

The specific embodiment

The amalgamation overwood is moulded the central layer formation between a kind of composite floor board employing solid-wood panels of the utility model and the wood floors; Said solid-wood panels becomes angle to intersect each other with the wooden lines of said wood floors; This angle is between 60 ° to 120 ° according to the gradient of plank wood grain lines, and said wood is moulded central layer and pieced together one through bonding glue-line and said solid-wood panels and said floor.

Eliminate effect in order to the utlity model has better stress, upper surface and/or soffit that the wood after amalgamation is moulded core layer can begin the stress groove, and in order to eliminate the stress of different directions, said stress slot cross-section can be dissimilar geometry.

For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done to describe in detail further below.

Be illustrated in figure 1 as the structural representation of the utility model first embodiment; Comprise: solid-wood panels 1 and wooden base plate 2; Amalgamation has wood to mould central layer 3 between said solid-wood panels 1 and the said wooden base plate 2; Said solid-wood panels 1 and said wood are moulded between the central layer 3 bonding through adhesive phase 31, and said wood is moulded between central layer 3 and the said wood floors 2 bonding through adhesive phase 32.

Said wood floors 2 are individual layer solid wood plate.

Wood grain lines between said solid-wood panels 1 and the said wooden base plate 2 formation angle that crosses one another.

Said angle is between 60 ° to 120 °.

Preferably, said angle is 90 °, the wood grain lines square crossing between both said solid-wood panels 1 and the said wooden base plate 2.

Preferably, in the present embodiment, said wood is moulded central layer 3 upper surfaces and is also offered stress groove 311, and said stress slot cross-section is a rectangle, in order to eliminate the stress that a kind of composite floor board of the utility model receives.

Be illustrated in figure 2 as the utility model second example structure sketch map, the difference of itself and first embodiment is that wood described in the present embodiment is moulded central layer 3 soffits and offered stress groove 311 in order to eliminate the stress that a kind of composite floor board of utility model receives.

Fig. 3 is the utility model the 3rd example structure sketch map, and in the present embodiment, said wood is moulded central layer 3 upper and lower surfaces and all offered stress groove 311, and said stress groove 311 cross sections are triangle, in order to eliminate the stress that a kind of composite floor board of the utility model receives; Said wood floors 2 are that two layers of plank are composited, the wood grain lines of the wood grain lines of said solid-wood panels 1 and said wooden base plate 2 each layers formation angle that crosses one another, and said angle is between 60 ° to 120 °.

Preferably, said angle is 90 °, the wood grain lines square crossing of the wood grain lines of both said solid-wood panels 1 and said wooden base plate 2 each layers.

Stress groove 311 stressing conditions as shown in Figure 4; Said stress groove 311 receives vertical power and is respectively F1 and F2; Said F1 said stress groove 311 1 sides be decomposed into level power F11 left with along the power F12 of stress groove tangential direction; Same, said F2 is decomposed into level power F21 to the right and power F22 along stress groove tangential direction at said stress groove 311 opposite sides, said F11 and said F21 is in the opposite direction cancels out each other; Thereby reduced the effect of stress to a great extent, reduced the probability that said composite floor board arches upward said composite floor board.

Above disclosedly be merely a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, the equivalent variations of therefore being done according to the utility model claim still belongs to the scope that the utility model is contained.
