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
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, Compossite solid-wood floor plate mainly is complex as the master with multi-layer solid wood.Its performance with three layers comparatively near pure solid wood.Three-layer wood composite flooring is to make the wood flooring that is shaped by three layers of thin solid wood board through complicated technique and staggered the combining of technology.Three layers of compound tense, thinner bottom and surface layer wood grain are longitudinal arrangement, thicker middle level wood grain is transversely arranged, thus the naturally distortion 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 preferably fast growing wood (as: pine, poplar etc.) of elasticity, can effectively solve wood flooring in varying environment because series of problems such as the buckling deformation of temperature, humidity variation generation and crackings.The precious wood of three-layer wood composite flooring surface course has not only kept graceful, the natural characteristic of wooden floor wood grain, and the resource of at utmost having saved the high-quality precious timber, can satisfy again people's liking precious timber.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 is poorer much than the pure wooden floor that wood grain is longitudinal arrangement, and the shortcoming of the wooden floor of longitudinal arrangement itself then is that buckling deformation occurs 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 preferably shear strength has again preferably anti-buckling deformation performance.
Realize that the technical scheme that above-mentioned purpose of the present invention adopts 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, the groove floor interval is processed with the hole of up/down perforation, is filled with 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 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, and do substrate layer with the fast-growing integrated timber, guaranteed the outward appearance class on floor, saved high-quality timber.When two kinds of materials adopt slash grain to arrange, can make the floor obtain larger 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.
Description of drawings
Fig. 1 is the main TV structure schematic diagram that substrate longitudinal grin of the present invention is arranged.
Fig. 2 is the dismounting panel plan structure schematic diagram that substrate longitudinal grin of the present invention is arranged.
Fig. 3 is the left sectional structure schematic diagram that substrate longitudinal grin of the present invention is arranged.
Fig. 4 is the main TV structure schematic diagram that substrate band of the present invention is arranged.
Among the figure: bridge muscle 1, pier stud 2, panel 3, substrate 4, groove 5, tenon 6.
The specific embodiment
Referring to Fig. 1~3, this solid wooden compound floor is formed by two-layer veneering, be that the wood grain trend of 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, the groove floor interval is processed with the hole of up/down perforation, 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 arrangement architecture of wood fibre perpendicular direction.Substrate adopts wood grain longitudinal arrangement structure as shown in Figure 2, groove direction vertical with grain direction (arrow is 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 preferably anti-buckling deformation performance, simultaneously can improve Transverse Shear Strength again, on the substrate 3 the groove cross section adopt rectangle or semicircle, groove depth is 10%~18% of substrate thickness.
Claims (2)
1. two-layer enhancing solid wooden compound floor, it is characterized in that: 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, the groove floor interval is processed with the hole of up/down perforation, is filled with bridge muscle and the pier stud of fiber-reinforced resin in groove and hole.
2. by two-layer enhancing solid wooden compound floor claimed in claim 1, it is characterized in that: the groove cross section of substrate is rectangle or semicircle, and groove depth is 10%~18% of substrate thickness.
