However, the connection between the core plate and the side plate of the utility model has weak resistance to deformation, and the core plate is entirely formed by splicing a plurality of forward wood strips, and the ability to resist lateral tile deformation of the composite floor is insufficient.

Summary of the invention

The object of the present invention is to provide a frame structure composite floor which can reduce the use of precious wood by using a panel layer of precious wood combined with a fast-growing wood as a base layer frame structure, and having a high decorativeness on the floor itself. On the other hand, this type of inclined hoe frame, through the novel hoe structure, can better resist the warping of the two sides of the composite floor when the floor installation and use environment changes, greatly reducing the floor under the condition of damp or air drying. The degree of deformation damage. The invention has the advantages of simple and effective structure, economical environmental protection and easy promotion.

The technical solution adopted by the present invention to solve the above problems is: a frame structure composite floor comprising a panel layer and a base layer, the base layer comprising a first elongated wood having an outer groove and a second long strip having an outer convex groove Wood and a short wooden strip disposed between the first elongated wood and the second elongated wood, the first long The inner side of the strip of wood and the second strip of wood are each provided with a downwardly inclined inclined head, and the short wooden strip is provided with a tongue and groove corresponding to the inclined head.

The first long piece of wood in the arrangement and the inclined hoe on the second long piece of wood make the long piece of wood and the short piece of wood more securely connected, the inclined hoe being in the form of a slanted downward direction, such that The base layer has two characteristics of being difficult to pull and separate in the horizontal direction and resisting the warping deformation on both sides of the composite floor after being installed by the environment. In the prior art, the hoe is disposed on the vertical surface and is horizontally perpendicular to the vertical surface. After the composite floor is affected by the cocking, the hoe of the horizontal state only receives the pressure of the vertical and the squatting surface, and the hoe is easily broken. In the present embodiment, the hoe is inclined downward, and when the short slat is lifted due to a change in the use environment, the lifting force can be divided into a pressure and an axial pulling force on the inclined hoe, that is, The inclined hoe has a diagonal downward force on the short wooden strip which is lifted up against the short wooden strip after the damp, which can function as a good anti-lifting function.

A further preferred technical solution is that the first elongated wood and the second elongated wood are respectively provided with an upper vertical side above the inclined hoe and a lower vertical side below the inclined hoe, A lower vertical side is located between the upper vertical side and the end surface of the boring, and a bottom support portion is formed between the upper vertical side and the lower vertical side.

The bottom support portion in the arrangement makes the overall volume of the inclined boring head large, greatly reducing the risk that the inclined boring head is broken by the force of the short wooden strip lifting, and is coupled with the grooving groove. The strength also becomes large, which ensures the strength of use of the base layer. On the other hand, the lower vertical side is closer to the inner side of the short wooden strip with respect to the upper vertical side, which makes the inclined hoe and the After the connection, the bottom support portion is located below the short wooden strip, which is capable of supporting the short wooden strip, especially when the short wooden strip is stepped on The wood is compacted, and the connection between the inclined boring head and the gutter is stronger and less likely to be disengaged due to the presence of the bottom support portion, and the risk of the slanting hoe breaking is also compared to the conventional squat structure. Greatly reduced.

A further preferred technical solution is that the bottom support portion includes a bottom portion connected to the inclined boring head and a mortise bottom connecting block disposed under the bottom of the boring head to provide the lower vertical side.

A further preferred technical solution is that the base of the boring head is provided with a pressure receiving surface on the base formed by the upper surface of the inclined boring head extending toward the upper vertical side.

Description The bottom of the hoe is used to assist the stabilizing hoe.

A further preferred solution is that the upper vertical side surface and the lower vertical side surface are parallel to each other and the distance between each other is 1/4-1/3 of the thickness of the first elongated wood.

The distance between the upper vertical side and the lower vertical side in the setting determines the thickness of the entire bottom support portion, and if the thickness of the bottom support portion is too small, the bottom support portion may be opposite. The stability effect of the inclined hoe is poor. On the other hand, when the thickness of the bottom support portion is too large, the volume of the first long wood and the second long wood is reduced, which affects the supporting effect, and The inclined hoe can be made to have a "small and pointed" shape characteristic, which seriously affects its resistance to anti-lifting, so that the thickness of the bottom support portion is sufficient to ensure the connection strength and resistance of the base layer. The key to the ability to ensure the anti-lift function of the entire floor.

A further preferred technical solution is that the short wooden strip is provided with an upper bearing portion above the gutter and a lower auxiliary locking portion located below the gutter, the lower vertical side and the inclined taro A locking groove is formed between the lower bottom surface and the lower auxiliary locking portion.

The volume of the upper bearing portion in the setting is larger than the volume of the lower auxiliary locking portion, such that the short wooden strip has a smaller area in contact with the ground under the same force receiving area, thus reducing the The moisture content of the foundation layer and the dampening situation are reduced; secondly, the damp condition generally extends upward from the ground, and the smaller lower auxiliary locking portion extends the water upward to the larger one under the damp condition The time required for the load bearing portion is substantially greater than the case where the lower auxiliary locking portion is larger than the upper bearing portion so that the damp transit time is greatly extended, giving the floor more time to recover moisture.

On the other hand, the upper bearing part can transmit a part of the force to the bottom joint piece of the hammer through the force receiving surface of the base body as the auxiliary support of the short wooden strip under the force of the short wooden strip. The integrity of the elongated wood and the short wooden strip is improved, and the connection strength between the two is increased, which improves the service life of the floor.

A further preferred solution is that the gutter includes an upper inclined surface, a lower inclined surface, and a vertical connecting surface, and the upper inclined surface forms an acute angle a with the vertical connecting surface, and the lower inclined surface An acute angle β is formed between the vertical connecting faces, and α<β.

In this arrangement, the magnitude relationship between the angle α and the angle β is reflected on the tilting head, that is, the connecting end of the tilting head and the bottom of the hammer is larger than the protruding end of the outer end of the inclined head, so that The inclined hoe is more stable and is not easily broken by the force of the short wooden strip, which further ensures the anti-warping of the base layer. Ability to start.

A further preferred technical solution is that the first elongated wood and the second elongated wood are respectively provided with an upper vertical side above the inclined hoe and a lower vertical side below the inclined hoe, The upper vertical side is located between the lower vertical side and the end surface of the boring head.

A further preferred solution is that the acute angle formed between the upper surface of the inclined boring head and the lower surface of the first elongated wood ranges from 20° to 50°.

A further preferred technical solution is that: the two ends of the base layer are disposed between the first elongated wood and the second long wooden wood, and the wood fiber direction is opposite to the panel layer, the first long wood, and the second long The direction of the wood fibers of the wood is parallel to the forward splicing block.

In the setting, the direction of the wood grain of the forward splicing block is parallel to the long axis direction of the composite floor, and according to the characteristics that the wood grain striate is better than the striated grain, compared with the composite floor with the horizontal wood texture at both ends, It is prone to the phenomenon of cracking of short wooden strips at the end of the floor.

The invention can reduce the use of precious wood by using the panel layer of precious wood combined with the fast-growing wood as the base layer frame structure, on the premise that the floor itself has high strength, and on the other hand, the inclined hoe frame form, through novel novel The structure of the hoe head increases the joint surface area of the 榫卯 joint structure. When the floor use environment changes, it can better resist the warping of the two sides of the composite floor, greatly reducing the degree of deformation damage of the floor under moisture or dry conditions. The invention has the advantages of simple and effective structure, economical environmental protection and easy promotion.
