Abstract

The invention relates to a solid wood floor, in particular to a two-layer enhanced solid wood composite floor. The composite floor is formed by bonding a solid wood panel with a solid wood substrate; wood grains of the panel and the substrate are compounded equidirectionally or in a staggered way; the upper surface and the lower surface of the substrate are provided with grooves which are vertical to a wood fiber direction and are over against each other; upper and lower through holes are formed at a certain interval on the bottom surface of each groove; and bridge ribs and pier columns filled with fiber reinforced resin are arranged in the grooves and the holes. The composite floor has a simple structure, comprehensive advantages of a pure solid wood floor and a multilayer composite wood floor, high shearing resistance and high bidirectional warping deformation resistance.

Description

Two-layer enhancing solid wooden compound floor

Technical field

The present invention relates to a kind of wooden floor, particularly a kind of two-layer enhancing solid wooden compound floor.

Background technology

At present, the composite wood floor is mainly compound based on multi-layer solid wood.Its performance is with three layers of comparatively approaching pure solid wood.Three-layer wood composite flooring is to lump together the wood flooring of making shaping by three layers of thin solid wood board through complicated technology and technology interleaved set.Three layers of compound tense, thin bottom and surface layer wood grain are vertically to arrange, and thicker middle level wood grain is transversely arranged, thus the distortion naturally of the timber that neutralized.The surface course of this three-layer wood composite flooring adopts the timber (as: oak, maple, teak are wanted, remote redwood is wanted, hickory nut, walnut etc.) of high-quality, intermediate layer, bottom then adopt elasticity fast growing wood (as: pine, poplar etc.) preferably, can solve effectively wood flooring in varying environment because temperature, humidity change a series of problems such as the buckling deformation that produces and cracking.The precious wood of three-layer wood composite flooring surface course has not only kept the characteristic of wooden floor wood grain grace, nature, and the resource of at utmost having saved the high-quality precious timber, can satisfy people's liking precious timber again.But in three layers of compound wooden floor, the heavy maximum intermediate layer wood grain fiber of accounting is transversely arranged, from total force analysis, its shear strength be than wood grain vertical arrangement pure wooden floor difference a lot, vertically the shortcoming of the wooden floor of arranging itself then is that buckling deformation takes place easily.

Summary of the invention

Technical problem to be solved by this invention provides a kind of two-layer enhancing solid wooden compound floor, and it is simple in structure, has the overall merit of pure wooden floor and multilayer composite wood floor, and existing shear strength preferably has anti-preferably buckling deformation performance again.

Realize that the technical scheme that above-mentioned purpose of the present invention adopted is: form composite floor board by two-layer veneering, the wood grain of panel and substrate in the same way or be staggered compound, the upper and lower surface of substrate have perpendicular to the wood fibre direction and mutually over against groove, groove floor is processed with the hole of up/down perforation at interval, is filled with the bridge muscle and the pier stud of fiber-reinforced resin in groove and hole.

The groove cross section of described substrate is rectangle or semicircle, and groove depth is 10%～18% of a substrate thickness.

The groove of described substrate is transversely arranged along the floor, or longitudinally arranges, or criss-cross arrangement.

The invention has the beneficial effects as follows: adopt high-quality timber to do the decorative cover flaggy, do substrate layer, guaranteed the outward appearance class on floor, saved high-quality timber and give birth to integrated timber with speed.When two kinds of materials adopt slash grain to arrange, can make the floor obtain bigger shear strength; Can increase the flexibility on floor when being staggered, reinforcing rib has then increased shear strength.Adopted the fibre resin reinforcing rib of many ring-type bandings to fix in the substrate layer, can two-way restriction and eliminate the buckling deformation of substrate, the reinforcing rib of this bridge-pier-bridge construction is two-way has offset the wooden distortion that changes with humiture.

The specific embodiment

Referring to Fig. 1～3, this solid wooden compound floor is formed by two-layer veneering, the wood grain trend that is surface layer 3 and substrate 4 is all for longitudinally, the upper and lower surface of substrate have perpendicular to the wood fibre direction and mutually over against groove, groove floor is processed with the hole of up/down perforation at interval, be packed into the bridge muscle 1 of fibre resin in groove, and be packed into the pier stud 2 of fibre resin in the hole, described fiber-reinforced resin can adopt high-intensity glass fiber or carbon fiber reinforced resin etc.Groove direction on the substrate 4 can adopt along the vertical arrangement architecture of wood fibre direction.Substrate adopts the vertical arrangement architecture of wood grain as shown in Figure 2, groove direction vertical with grain direction (arrow is a grain direction) according to actual laying condition needs; Also can adopt substrate wood grain shown in Figure 4 to be laterally, groove direction is vertical with grain direction.Such structure had both obtained anti-preferably buckling deformation performance, simultaneously can improve horizontal shear strength again, on the substrate 3 the groove cross section adopt rectangle or semicircle, groove depth is 10%～18% of a substrate thickness.
