Abstract

The invention relates to a method for stiffening a sheet (1) of solid wood and a sheet of wood. The sheet of wood consists of an integral piece of wood or a plurality of wood strips which are joined together and have substantially parallel grains. By means of the method of the invention, the sheet (1) of wood is stiffened to prevent the substantially straight sides (4) of the sheet from bending. The stiffening member (8) does not form any projections and does not cause any disadvantageous crack formation in the sheet of wood, which would damage the protective surface treatment. On account of the stiffening member (8) which is provided completely inside the sheet of wood, the product obtained is easy to handle, and its manufacture can be easily automated.

Description

A kind of plank reinforcement means and a kind of plank

The present invention relates to the method for the solid plank that a kind of batten that is used for reinforcing the parallel grain that combined by monoblock timber or several and have constitutes, described plank comprises two parallel sides.

This method can make a plank obtain reinforcing, with the edgewise bend that prevents that plank is very straight.

The invention still further relates to a kind of solid plank, it is combined by a monoblock timber or several and has the batten of parallel grain to constitute, and described plank comprises two parallel sides.

The greatest problem that this solid plank uses is, they change or other variation is tending towards crooked when causing internal stress at damp condition.Existing in the past have processing as batten door, and it is made up of one or more laths of being made by solid plank.Each lath is centered on by frame part; Frame part perpendicular to the plank texture is used to reinforce plank and prevents the plank bending thus.

Existing also have for example connect a reinforcing wooden stick or metal bar is reinforced the solid wood desktop by lower surface at desktop.

But above-mentioned existing technology is had any problem adding man-hour, and comprises clumsy framework or rod member on the surface of plank, and this makes that the use of plate is complicated.In addition, this projection makes that the maintenance of this structure is very difficult, for example cleans.Make a frame structure closely attached to also difficulty relatively on the plank in addition, the slit can appear in the junction after after a while between plank and frame part.Moisture can enter plank along the slit, thereby can make the plank bending.And existing ruggedized construction is difficult to automated production, and this makes product expensive.

The present invention has avoided the problems of the prior art, and a kind of method of reinforcing plank is provided, and it can easily be processed automatically.

Can obtain a kind of solution to the problems described above by the present invention, its feature obtains open in the claims.

The inventive method is characterised in that a hole is set on plank at least, this hole is set as perpendicular to the texture of plank and along parallel plank side surface direction to be run through whole plank or only passes through a part, a girth member is inserted in this hole, and seal this hole with a closure member.

Plank of the present invention is characterised in that this plank has a hole at least, and this hole is run through whole plank or only passed through a part perpendicular to the texture of plank and along parallel plank side surface direction, is inserted with a girth member in this hole, and Kong Youyi closure member sealed.

The present invention is based on following consideration, reinforce a plank and should not be in the plank and to add any projection or to produce any disadvantageous gap structure.These projections or slit can be damaged the protection on plank surface and handle.The present invention has also eliminated the variation of the plank stress situation in the process of for example milling at the plank surface scan.

This plank is made with glued lamination board usually, and wherein the batten that combines with binding agent can be any timber.

Method and apparatus of the present invention has many good qualities compared to prior art.The processing of plank of the present invention can realize automation fully with simple mode.The present invention also provides a kind of plank, because this structure has minimum slit, therefore has moisture resistance preferably, so this plank can keep shape preferably than prior art under varying environment.

Plank of the present invention especially can be used for the processing of door or cupboard door.Because the door of a bending can not be closed a doorway or cupboard very rightly, therefore make these products keep very straight just very important.

Common solid timber is a batten door, and door-plate is centered on a following vertical frame part by a last vertical frame part.These frame parts play girth member.The purpose of this invention is to provide a girth member, the texture of its vertical door-plate also can substitute frame part separately.According to the present invention, a door-plate that is equivalent to the common batten door that has framework can be by processing on outer side milling to the solid plank that will will be clear that profiling.

Because the processing of calling to a great extent can automation, thus with method of the present invention than making that with existing method the processing cost of product is cheaply a lot.In addition, product processed is handled easily according to the present invention.Constitute because this product mills the even plank that forms of system by its surface portion, so product surface do not comprise lath or frame part, these laths or framework may since processing fluff because of carelessness.Because the chamber, hole or the slit of not assembling foul or moisture, door of the present invention also is easy to clean very much, and therefore product of the present invention is lower than the upkeep cost of existing product.

Describe the present invention below with reference to accompanying drawings in detail, wherein:

Figure 1A to 1D is the schematic diagram of the inventive method,
