Abstract
The invention relates to a dipped paper mould pressing wood flooring block which is a wood floor, comprising a surface structure, a base material and a bottom layer. The surface structure comprises a wear-resisting layer, a surface layer and a decoration layer. The bottom layer is a decorative paper board of dipping thermosetting resin, or veneers. The base material is density fiberboard provided with a tenon and a groove which are adapted with each other and arranged at the edge of an opposite edge of the base material. The surface structure and the base material are overlapped with an edge contour area and a central area below the surface area of the walking surface; a dent-shaped strip of an arc-shaped line segment section contour with a symmetry axis vertical to the bottom surface of the floor block is pressed at the overlapped surface structure and base material. The invention provides dent-shaped strip with a cross section that is designed to accord with the press working principle, reduces the stress concentration and is provided with the waveform dent-shaped strip extending along the longitudinal direction in the central area, thereby enhancing the bending section coefficient, i.e. the bending strength. The invention can be widely paved in fields such as hotels, houses, schools, hospitals and the like.
Description
Technical field
The present invention relates to a kind of timber floor, especially a kind of dipped paper mould pressing wood flooring block.
Background technology
Timber floor in use, experience informs, the most flimsy is the edge, often first abrasion herein of timber floor, arrisdefect then, and then can relate to adjacent regions accelerates at last full wafer and destroys.For this kind bad phenomenon, the designer has taked improvement on structure and technique.The manufacturing process of impregnated-paper laminated wood floor commonly used is that impregnated paper is pressed on the base material that is arranged on the press platform under 2400 tons of left and right high pressure and 200 ℃ of left and right high temperature actions by the template on forcing press at present.Improved structure and technique are the patterns that is pressed with in advance design on special steel template, therefore in the impregnated-paper laminated wood floor pressing formation also surface structure and the base material in timber floor extrude the indenture shape bar of design configuration in advance.Cut being adjacent to the abandon plane of symmetry of the indenture shape bar that closes of plate periphery and synchronize also having of carrying out with the pressing of above-mentioned full wafer timber floor and indentation process, just can form the monolateral indenture shape bar of each floorboard surface structure and base material superimposed edge, thereby at surface structure and generation hole, base material edge profile, to preventing the generation of above-mentioned bad phenomenon.then in order to prevent that surface structure from coming off and the sepage phenomenon of timber floor edge notches, again with the central area of this process application to surface structure and base material, as described in CN2921164Y (day for announcing 2007.07.11) and CN1485184A (open day 2004.03.31), namely also suppress the V-shaped indentation line of cross-sectional profiles that wave longitudinally extends in surface structure and base material central area, because superimposed central area is pressed with the V-arrangement indentation line, the sepage phenomenon of central area has reduced, the whole bending resistant section coefficient of surface structure increases simultaneously, the bending resistance of surface structure, particularly the raising of bending resistance has important meaning longitudinally.But because pressure processing certainly exists at the V-arrangement sharp corner phenomenon that stress is concentrated, there is certain squeeze crack risk in the swaging of in fact above-mentioned V-arrangement at sharp corner.
Summary of the invention
The object of the invention is to eliminate the stress concentration phenomenon of this timber floor swaging operation, to reduce defective products and to improve the quality of products.
The present invention includes surface structure, base material and bottom; Surface structure comprises wearing layer, top layer and decorative layer, bottom is the decorations cardboard of heat of immersion thermosetting resin, it can be also wooden skin, base material is density fiber board, base material has adaptive tenon and groove in relative edge's edge, and surface structure and base material be an overlapping edge contour district and a central area under the face territory of walking surface; Overlapping surface structure and base material are pressed with symmetry axis perpendicular to the indenture shape bar of the combined cross section profile of circular arc line segment of floorboard bottom surface.
As a further improvement on the present invention, the compacting filleted corner that the shaping bull nose that above-mentioned cross section profile is connected by the line segment of symmetry, line segment upper end is connected with the line segment lower end forms, and integral body is shape wide at the top and narrow at the bottom.
As a further improvement on the present invention, the cross section profile of above-mentioned indenture shape bar is connected to form by the compacting filleted corner that the line segment of symmetry is connected with the line segment lower end, and integral body is shape wide at the top and narrow at the bottom.
As a further improvement on the present invention, the high H scope of the shape of the cross section profile of indenture shape bar is 0.66mm～1.00mm, and top width W scope is 1.40mm～4.00mm; The preferred high H of shape is 0.80mm, and top width W is 3.50mm.
As a further improvement on the present invention, the radius of the shaping bull nose of cross section profile and compacting filleted corner is 0.20～12mm, preferred radius 0.80mm～1.20mm; The radius of the shaping bull nose of most preferred cross section profile and compacting filleted corner equals 1mm.
As a further improvement on the present invention, the surface structure of adjacent splicing-in floorboard and base material overlapping marginal zone periphery under the face territory of walking surface respectively is pressed with 1 indenture shape bar of abandoning and closing; The surface structure of floorboard and base material overlapping central area under the face territory of walking surface is pressed with the indenture shape bar more than 1.The indenture shape bar of central area can be parallel to each other along longitudinal direction extension and track by undulate.
The invention provides a kind of cross section profile has the indenture shape bar of compacting fillet, has reduced the stress concentration phenomenon of extrusion process; And because the central area is pressed with wave along the indenture shape bar that longitudinal direction extends and track is parallel to each other, improved the bending resistant section coefficient of surface structure, also namely improved the bending strength of surface structure, particularly bending strength longitudinally; The compacting fillet is arranged at the bottom due to the cross section of indenture shape bar again, has reduced osmotic pressure, can further improve the sepage phenomenon of timber floor edge notches.The present invention can be widely used in the places such as hotel, family, school and hospital and lay use.
