A kind of multi-layer solid wood floorTechnical field
It the utility model is related to a kind of timber floor, more particularly to a kind of multi-layer solid wood floor.
Background technology
Multi-layer solid wood floor is using the multi-layer sheet of criss-cross arrangement as base material, selects high-quality precious timber as panel, warpResinize and be made in hot press by HTHP after glue.Cracking is unlikely to deform, drying shrinkage expansion is minimum, is had preferableRegulation room in temperature and humidity ability, surface layer can show timber natural wood grain, mat formation simple and direct, use range is wider.ValencyLattice are higher than composite floor board, less than solid wooden floor board.It is adapted to the installation of geothermal heating system room.Its specific manufacturing step is：
The first step：The floor that the timber that log selection has been split can just go out, log quality over the ground plate quality influence extremelyClose important.
Second step：Rounding dries the solid wood core that this procedure is used for processing and fabricating Multilayer solid wood composite floor base materialPlate, wood base material solid core plate quality are inseparable with the quality on finished product floor.About 1.5 millimeters of the solid wood core plate thickness that circumgyration incision goes out,Also need to be dried for a period of time after rotary-cut.
3rd step：Solid wood core plate sorts.In order to ensure the quality per a piece of floor, only select that thin and thick is uniform, thickness is moderate, andZero defect, the solid wood core plate without fracture are selected floor base material as floor base material by full-time sorting person.
4th step：The automatic double surface gluer of core plate gluing row's plate specialty is operated, it is ensured that glue-spread is uniform, improves and appliesGlue operating efficiency.By the thin solid wood core plate of the coated glue of 8-10 layers crisscross hierarchal arrangement in an orderly manner, it is bonded together, Ke YigaiBecome the original direction of extension of lumber fibre.Exactly this step, thoroughly improve the limitation of the moisture expansion and drying shrinkage of solid wood.
5th step：Core plate hot-press gluing.Hot pressing is an important procedure in solid wooden compound floor production process, and it is directIt is related to the quality of ground board finished product.
6th step：The fixed thick sanding of base material.Face, the bottom of floor base material are carried out using large-scale contact calibrating machine to determine thick sanding,The flatness and finish of plate face are can ensure that, so as to improve the precision of product, is carried for overlaying for architectural surface rare tree wood skinFor Reliable guarantee.
7th step：Base material sorts health.Floor base material will also meticulously be sorted by special messenger, gone after the completion of preparatory processingFall underproof product.By HTHP, larger internal stress inside base material be present, it is necessary to stand 15 days to a 20 days left sides of balanceRight this internal stress of release so that base material balance and stability.This process is called health.
8th step：Solid wood musculus cutaneus is selected.Multi-layer solid wood composite floor is used in the environment that the north is dried, therefore sizeStability is most crucial.In order to prevent dry heating season is cracking phenomena such as, the preciousness on solid wooden compound floor surfaceWood kind wood skin is all selected one by one by professional quality inspection personnel, and moisture control is extremely strict.
9th step：Floor slab is molded.The wood skin monolithic of select is coated into environment-friendlyadhesive adhesive to be attached on floor base material, entered back intoHot pressing is carried out in advanced hot press, that is, qualified multi-layer solid wood composite floor slab is made.
Tenth step：Floor slab health.Because floor base material passes through hot pressing after decoration wood skin is sticked again, slab inside is againLarger internal stress is generated, such floor slab needs to stand 20 days left sides of health in the balance health-preserving storehouse of constant temperature and humidityThe right side, so as to ensure that floor quality is more stable.
11st step：Floor cutting fluting.Health is have passed through, slab will pass through fluting apparatus excision forming.
12nd step：Leaching paint dryness finalization.The floor of groove is ended, flow coating equipment will be passed through.By eight priming paint, fourAfter the showering of finish paint, the surface lacquer painting on finished product floor, which will have, moistens and rich in toughness.Afterwards, packaging only need to be sorted, just terminatedProduction overall process.
Following defect be present in existing multi-layer solid wood floor：
1st, water resistance is poor, and user, if ponding is on solid wooden floor board, will result in solid wood during useFloor is bubbled, and is swollen, mouldy, can not be reused, be leveraged the service life of solid wooden floor board.
2nd, plywood needs to be bonded together with glue, and has the presence of formaldehyde in glue, causes multi-layer solid wood floorFormaldehyde generation is had during use, it is not environmentally friendly enough.
Utility model content
In order to overcome drawbacks described above existing for existing solid wooden floor board, the utility model provides a kind of multi-layer solid wood floor,The solid wooden floor board water resistance is good, there is ponding in the short time in timber floor, will not also cause the foaming of timber floor, swell, mouldy,The service life of timber floor is extended, due to reducing the use of glue, just reduces the formaldehyde brought due to the introducing of glue,Environmental protection safe to use.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of multi-layer solid wood floor, including plank body, it is characterised in that：Set in the side of the length direction of plank bodyRaised the first length, the first length groove and the second length groove are equipped with, is provided with the length direction opposite side of plank body3rd length groove, the 4th length groove and the second length are raised, and first length is raised and the 3rd length groove is relative setsPut and be adapted, the first length groove and the 4th length groove are oppositely arranged, the second length groove and the second lengthProjection is oppositely arranged and is adapted；It is recessed that the first width projection, the first width are provided with the side of the width of plank bodyGroove and the second width gap, the width opposite side of plank body be provided with the 3rd width gap, the 4th width gap andSecond width is raised, and first width is raised and the 3rd width gap is oppositely arranged and is adapted, first width gapIt is oppositely arranged with the 4th width gap, second width gap is oppositely arranged and is adapted with the second width projection；Polylith woodAfter the splicing of plate body, in the longitudinal direction, in first length the 3rd length groove of raised insertion, the first length grooveConnect with the 4th length groove, form drainage channel, second length is raised to be inserted in the second length groove；In widthOn, in first width the 3rd width gap of raised insertion, first width gap and the 4th width gap connect, and are formedDrainage channel, second width is raised to be inserted in the second width gap；The plank body includes multi-layer solid wood thin plate, connectionPart, bottom plate and panel, set on the multi-layer solid wood thin plate and be stacked together with multiple through holes, the multi-layer solid wood thin plate, evenFitting is inserted into through hole, multi-layer solid wood thin plate is linked together by the effect of connector, bottom plate is bonded in by glueThe bottom of the multi-layer solid wood thin plate to link together, the panel are bonded in the multi-layer solid wood thin plate to link together by glueTop.
