Abstract

The utility model relates to a distortionless floor core wood. A solid wood core can be a board material which is formed by split joint and finger joint. The distortionless floor core wood is characterized in that longitudinal grooves 1 which are arranged on the two longitudinal planes of the solid wood core at intervals in a stagger mode, and transversal holes 2 are arranged on the longitudinal profile of the solid wood core. The distortionless floor core wood not only maintains the characteristics of a solid wood core floor and makes a heat source line more approach to the earth surface, but also improves the heat efficiency while the deformation of the floor is not generated because of the structure of core wood grooves. The deformation which is caused by the change of the water content of the wood material can be eliminated and dispersed in the small areas among the grooves. Take into consideration that the core wood is formed by the split joint of crushed aggregates of different wood materials, the utility model is difficult to guarantee that the wood grains are all in positive directions. Skewed grooves 3 can be arranged on the utility model.

Description

Deformation-free floor core wood

Affiliated field

The utility model relates to a kind of flooring structure, particularly is suitable for the deformation-free floor core wood of geothermal heating.

Background technology

In order to realize undeformed this optimum efficiency on floor, those skilled in the art still is that shape, the structure of sheet material all done many improvement from the processing technology of timber for many years.For preventing sheet deformation, great majority all be with wooden part cut open, attenuation, destroy the fibre tension of log self, for example, layer of wood has been the glue box plated construction of thin paper, the deformation of its timber is almost nil.Yet people are when selecting the floor for use, and for to the trust of former wood flooring quality, to the high praise psychology of back to nature, still first-elected former wood flooring is top grade.Yet for overcoming the contradiction between the natural timber resources protection and the market price, the main flow of current floor product is solid wood core, the two-sided shaped sheet that the wood grain veneer is arranged.The solid wood core has only joint wedge mouth, is in order to save timber, not outstanding anti-deformation function.Particularly the geothermal heating technology of popularizing in recent years is embedded in heat release cable or hot-water line shop under the floor, and floor and thermal source have more been given prominence to the deformation problems of solid wood or folder wood flooring apart from the inequality of more closely and on the whole being heated.

Summary of the invention

The purpose of this utility model provides a kind of deformation-free floor core wood, and the thermal source pipeline is placed through in the solid wood core, improves the thermal efficiency.

The design's deformation-free floor core wood, solid wood core can be the sheet material of splicing, finger, it is characterized in that having on vertical two planes of solid wood core staggered groove at interval, at longitudinal profile transverse holes are arranged.

The design's deformation-free floor core wood promptly keeps the characteristics on solid wood core floor, makes thermal source wire more approach the face of land again, has improved the thermal efficiency and the floor deformation can not take place.This has benefited from core wood groove structure, and it makes the deformation that timber takes place because of change of moisture content obtain in the zonule disperseing to dissolve between groove and groove.And consider that core wood adopts different wooden short material splicings, be difficult to guarantee that wood grain all is along stubble, also can leave skewed slot.

The specific embodiment

A kind of deformation-free floor core wood, used solid wood core can be the sheet material of splicing, finger, it is characterized in that having on vertical two planes of solid wood coreboard staggered longitudinal groove 1 at interval, the degree of depth of groove is not more than half of core wood thickness, the width of groove is to present ditch; At longitudinal profile transverse holes 2 is arranged, hole and slot part intersect vertically.

Core wood adopts different wooden short material splicings, is difficult to guarantee that wood grain all is along stubble, also can leave skewed slot 3.

Claims

1, a kind of deformation-free floor core wood, the solid wood core can be the sheet material of splicing, finger, it is characterized in that having on vertical two planes of solid wood core staggered longitudinal groove (1) at interval, at longitudinal profile transverse holes (2) is arranged.

2, deformation-free floor according to claim 1 core wood is characterized in that two faces of real core wood have skewed slot (3).
