Abstract

The utility model discloses a multilayer parquet floor. Each floor core material is formed by laminating three layers, namely a bottom layer, a middle layer and a surface layer, wherein the bottom layer is a veneer, the middle layer is multilayer plywood, and the surface layer is a patterned veneer. A floor base material is formed by splicing sixteen square floor core materials, wherein each floor core material is provided with two adjacent middle layers which are recessed to be mortises and another two adjacent middle layers which are protruded to be tenons; the tenons and the mortises of the sixteen square floor core materials are spliced by using grooves and tongues which are firmly adhered to one another through glue; and a telescopic seam of 2 mm is reserved between the top of each tenon and the bottom of each mortise. By adoption of the multilayer parquet floor, the defect that the conventional solid-wood composite parquet floor is easy to deform due to dampness is overcome, the telescopic seam is reserved in each piece of core plate groove and tongue, residual stress which is generated in the hot-press process can be eliminated, and the practical problem that large and ultra-thin veneer solid-wood composite parquets cannot be produced because the core material of the conventional solid-wood composite parquet floor is easy to deform is solved.

Description

A kind of multilayer parquet

Technical field

The utility model relates to architectural decoration material field, refers in particular to a kind of multilayer parquet.

Background technology

Along with state-of-the-art raising, modern's habitat environment is also using the increasingly high adornment of scientific and technological content.Industrial design is also had higher requirement to the requirement of current home decoration when main building having been proposed more attractive in appearance, environmental protection, requirements of saving energy.It only is the most basic demand that the function of dwelling environment realizes, to the interior quality of ornament materials, like durable, environmental protection, attractive in appearance, ease for maintenance, texture or the like deeper requirement has been arranged also.

In the floor decorative material of household, wood flooring especially wooden floor remains current main ground construction material, with its ease for use, aesthetic property, durability, texture is good and obtain majority's approval, so be widely used.Wherein, wood flooring is because of having damp proof insulation, insulation, and multiple advantage such as lines is relatively more natural, pattern is clear, attractive in appearance, life cycle is long and being used widely; Especially wooden floor has been represented the high-end product image in the floorboards of wood especially, and enjoys people's favor, and the natural sex of wooden floor itself, the feature of environmental protection, health idea are rooted in the hearts of the people especially.But require too highly to raw-material in the wooden floor processing, and stock utilization is low, thus expensive be difficult to realize the balance between supply and demand, be difficult to let ordinary people buy and bear.On the other hand, because of in the process of other wooden furnitures or woodwork, a large amount of leftover pieces that produce can not obtain suitable utilization, thereby produce bigger waste, and as utilizing composite material, with solving the problem that this waste material utilizes again.

Parquet can utilize wood waste to a certain extent, but that traditional solid wood composite block floor makes moist is yielding, thereby can not produce the compound parquets of solid wood of big specification and special sake skin.

Therefore, how can realize environmental protection requirement, and can provide cheap again, the floor that ordinary people can be consumed just becomes a problem.

Summary of the invention

The utility model has overcome the some shortcomings of prior art, and purpose is a kind of multilayer parquet of providing performance more superior.

The goal of the invention of the utility model realizes through following technical scheme: a kind of multilayer parquet, flooring structure by bottom, intermediate layer and surface layer totally three big laminations paste and form; Wherein, bottom is a veneer, and the intermediate layer is the sandwich construction veneer, and surface layer is the different parquets wood skins of floral designs.

This uses novel described a kind of multilayer parquet; Floor base material be by 4 * 4 totally 16 or 3 * 3 totally 9 foursquare ground board core materials be put together; Each board core material foursquare as elementary cell has that the intermediate layer of two adjacent edges is recessed to be tongue-and-groove, and the intermediate layer protrusion of two other adjacent edge is tenon, and the tenon of board core material and tongue-and-groove splice with tongue and groove foursquare; Be glued between the tongue and groove firmly, leave the shrinkage joint of 2mm between tenon top and the tongue-and-groove base.

This patent has overcome the shortcoming of traditional solid wood composite block floor moisture-sensitive distortion, and every fritter central layer tongue and groove leaves the shrinkage joint, and can eliminate the residual stress that produces in the hot pressing.This patent has solved general traditional solid wood composite block floor can not be produced big specification and the compound parquets of the sturdy wood of special sake owing to the yielding reason of core actual property problem.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done detailed description.As shown in Figure 1, a kind of multilayer parquet, flooring structure bybottom 3,intermediate layer 2 andsurface layer 1 totally three laminations paste and to form; Wherein,bottom 3 is a veneer, andintermediate layer 2 is a multi-plywood, andsurface layer 1 is the different parquets wood skins of floral designs.

As shown in Figures 2 and 3; A kind of embodiment of the described a kind of multilayer parquet of the utility model, floor base material be by 4 * 4 totally 16 foursquare ground board core materials be put together, each board core material foursquare as elementary cell has that the intermediate layer of two adjacent edges is recessed to be tongue-and-groove 22; The intermediate layer protrusion of two other adjacent edge istenon 21; As shown in Figure 4,16foursquare tenon 21 and the tongue-and-groove 22 of board core material be glued between the tongue and groove firmly with tongue andgroove 23 splicings.As shown in Figure 5, leave the shrinkage joint 24 of 2mm betweentenon 21 tops and tongue-and-groove 22 bases.
