Description

Vertical blank and method for manufacturing and using the same

The invention relates to a vertical blank used in wood products, such as buildings and other shelters, including two or more lumber blanks. The invention also relates to a method for manufacturing a vertical blank and for using it in wood products.

An essential problem with wood products is that the measures of blanks are changed owing to the gradual drying of the blanks. The deformation is often so drastic that when using conventional log beam blanks, it is necessary to apply complicated structural solutions. This problem has existed for decades, but functional technical solutions have not been found.

General description of the invention

We have now invented a vertical beam blank, the use of which in various targets is technically extremely simple.

For achieving this aim, the invention is characterized by features that are enlisted in the independent claims. Other claims represent preferred embodiments of the invention.

By using structures according to the invention, it has also been possible to make the manufacturing of the structures simpler, which brings forth both technical and economical benefits.

In a vertical beam blank according to the invention, at least two wood blanks are connected by one or several connecting pieces. This technical solution essentially reduces internal expansion in the blank as well as shrinking caused by moisture and temperature, so that the structure becomes particularly stabile and strong. A vertical blank is structurally advantageous, because it does not remarkably shrink/expand in the vertical direction as the moisture and/or temperature fluctuate. This essentially simplifies for example the structural solutions of a building. Advantageously wood blanks are connected at a mutual distance, so that in between the wood blanks, there is arranged one or several connecting pieces.

A vertical blank includes one or several connecting elements, such as connecting parts, connecting projections and/or connecting recesses for connecting the vertical blank to another vertical blank and/or to other structures of the wood product. Technically the use of this kind of vertical blank in wood products is extremely simple.

Advantageously there are provided one or several connecting elements at the top and bottom end, such as fastening projections and/or fastening recesses for fastening the vertical blank at its top and bottom end to other structures of the wood product. The use of this kind of s vertical blank for instance in buildings is technically very simple. By means of this solution, also damages caused in structures by expansion and shrinking can effectively be prevented. Owing to the connecting elements, check measurements are not needed in the installation step of the vertical blank. Also the need for temporary installation supports is minimal in comparison with the conventional technique.

In the vertical direction of the structures, it is not necessary to take into account vertical changes in the measures, as the degree of moisture varies.

The blanks according to the invention are lighter than for example conventional log blanks. The vertical blanks used in a wooden house weigh about 10 - 50 kg/piece, in which case they are easy and safe to handle. The installation of vertical blanks does neither require any special tools nor a truck crane or other heavy equipment. The installation can be realized simply by means of a crosshead screwdriver or an Allen key, for example.

Advantageously the top and bottom ends are provided with connecting elements that are with respect to each other placed at essentially the same edge location in the vertical blank. Preferably the connecting elements are placed at essentially the center point between the top and bottom ends of the vertical blank. These arrangements can further effectively help in preventing possible damages caused by expansion and shrinking in the structures.

According to an embodiment of the invention, the top and bottom ends of the vertical blank are provided with connecting elements that are with respect to each other placed at essentially the same location in relation to the center axis of the vertical blank. In this solution, the vertical blank is capable for expanding freely in the other width direction. This is particularly advantageous, because the vertical blank is not subjected to internal tensions, in which case the structures of the vertical blank remain unbroken essentially better during fluctuations in the temperature and moisture. There are not created any fractures or ruptures that should reduce the strength of the blank and deteriorate its heat insulation. Also the working life of the vertical blank is extended, because the surface of the blank remains unbroken.

According to an embodiment of the invention, the top and bottom ends of the vertical blank are provided with connecting elements that are placed essentially at the center of the vertical blank. In this arrangement, the vertical blank is capable of expanding freely to both width directions. This is particularly advantageous, because the vertical blank is not subjected to internal tensions, in which case the structures of the vertical blank remain essentially better unbroken as the temperature and moisture fluctuate. There are not created fractures or ruptures that should weaken the strength of the blank and deteriorate its heat insulation. Also the working life of the vertical blank is extended, because the blank surface remains unbroken.

Advantageously at least one edge and/or frontal surface of the vertical blank is provided with one or several connecting elements for connecting the vertical blank to another vertical blank. The use of this kind of a vertical blank as a wood product is technically extremely simple, because the vertical blanks can be connected together extremely rapidly and precisely. These connecting elements make the structure very compact.

According to an embodiment of the invention, a vertical blank is connected to another blank, so that the edge and/or end of the vertical blank is essentially attached to the edge and/or end of the other blank. This kind of joint is advantageous for example when connecting two horizontal blanks together, or when connecting vertical blanks so that they rest against horizontal blanks.

According to an embodiment of the invention, a vertical blank is connected to another vertical blank, so that the edges and/or ends of the vertical blank and respectively those of the other blank are located at a mutual distance. This kind of connecting method is advantageous for instance when connecting vertical blanks to each other, or when connecting a horizontal blank located above an aperture to vertical blanks. For example in a log blank of 300 mm, the expansion caused by moisture is about 3 mm, when the degree of moisture increases from 50% to 70%. Advantageously the edges of the vertical blank and of the other blank are located at a mutual distance of 1-25 mm. In an extremely advantageous case, the edges of the vertical blank and the other blank are located at a mutual distance of 3-10 mm. In this kind of a technical solution, a sufficient space is left between the vertical blanks. Possible changes in measures are not multiplied, because they are restricted to one blank only. On the other hand, the gap is still sufficiently small in order to be sealed for instance by means of a separate sealing or strip.

According to an embodiment of the invention, the connecting projection is a connecting shoulder, connecting pin and/or a connecting mounting. These are technically easily fastened or made in a vertical blank, and they are particularly advantageous for example in the installation of the blank. Preferably there are arranged one or several connecting projections at the end of the connecting piece.

The wood blank of a vertical blank according to the invention can be made of different materials. It can be made of for instance plywood, preservative-treated wood, laminated wood, whole wood or adhesive wood blank. For example by using an adhesive wood blank, the outer surface of the wood product is made particularly good-looking and technically durable. This kind of adhesive wood blank also is advantageous in use, because the wood blank has a low heat transfer coefficient, which means that it also in part serves as heat insulation. A wood blank made of plywood or laminated wood in turn is well resistant to moisture. By using different materials, also the appearance of the wood product can advantageously be affected. By connecting blanks where plywood and/or laminated wood are used together in a compact fashion, the obtained wall structure is a rigid structure resistant to wind loads.

According to an embodiment of the invention, vertical blank wood blanks are made of mutually different materials. For example, it is advantageous to use adhesive wood blank in the outer surface, and plywood or laminated wood in the inner surface. This helps to further simplify the wood product structures. The use of this kind of wood blank in a wood product is technically extremely simple, because the inner surface can be directly coated, such as dressed with tiles. The wood blank can have one or several layers.

According to an embodiment of the invention, the edge or surface of the vertical blank is provided with one or several connecting grooves. Advantageously the connecting groove is arranged at the edge or surface of the wood blank for installing one or more binding strips. Preferably at least one edge and/or frontal surface is provided with one or several connecting grooves for installing a binding strip in order to connect the vertical blank to another vertical blank and/or to other structures of the wood product. The binding strip binds the vertical blanks together and at the same time provides a good sealing in between the vertical blanks. The binding strip is preferably narrower, for example 1-3 mm narrower, than the mounting groove formed by the joined connecting grooves. This kind of binding strip seals the structure, but is not broken as the measures of the blanks are changed.

The use of connecting grooves and binding strip simplifies the manufacturing of for instance inner and outer comers. Advantageously the same wood blank structures can be used both in corners and in other parts of the wood product.

According to an embodiment of the invention, the opposite edges of the log blank are provided with one or several connecting grooves. The deformations caused by the drying of a log blank of this kind can be extremely well controlled. The symmetrical structure also is advantageous for the log blank structure, for example in that the twisting of the blank is reduced.

Preferably a vertical blank constitutes a single-layer wood blank. This kind of wood blank can be made directly of lumber by simply cutting and planing. Advantageously the opposite edges of a wood blank of this kind are provided with connecting grooves for installing the binding strip. This kind of a blank can advantageously be used for connecting other elements, and its symmetrical structure is an extra advantage as such.

According to an embodiment of the invention, the surface of a vertical blank is provided with one or several connecting grooves. The connecting grooves arranged on the surfaces can advantageously be used for example in angle joints or when connecting partition walls with a log blank according to the invention.

According to an embodiment of the invention, the connecting piece of the vertical blank is made of wood, fiberboard and/or plywood, or a combination of these. These kind of connecting pieces are easy to use as connecting projections or connecting recesses. They are easily treated industrially for example for mountings/connecting pins prior to the assembly of the blank. When using plywood or laminated wood as the connecting piece, it can be made thinner, which further improves the functional usability of the blank, and at the same time the insulating capacity of the blank is improved.

According to an embodiment of the invention, between the connecting piece and the wood blank, there is one or several connecting projections and respectively one or several connecting recesses, such as connecting pins and connecting holes and/or feathers/feather grooves and/or connecting grooves and binding strips. This is particularly advantageous in the blank assembly, because the elements can be mutually aligned in a simple and precise fashion. In that case separate check measurements are not needed.

The use of a binding strip advantageously minimizes the use of the raw material. There are not needed large working allowances when profiling wood blanks and connecting pieces. The making of grooves in the binding strip also is easily done.

In addition, blanks according to the invention can be advantageously used in the installation of pipes, wires etc., because inside the log blank, between the wood blanks, there is left suitable free space. With this arrangement, for example the installation of water pipes and electric wires is technically essentially simplified in comparison with conventional structural solutions. Preliminary installations can advantageously be carried out prior to the assembly of the vertical blanks.

According to an embodiment of the invention, heat insulation is installed inside the blank. This improves the heat and sound insulation of the structure. It also affects the acoustics in the structures.

According to an embodiment of the invention, at the end or edge of the vertical blank, and/or in the wood blank there is arranged one or several bracings. A bracing is advantageous in the installation of the blank. It also is advantageous in the sealing of the structures.

According to an embodiment of the invention, at least two vertical blanks are attached together at their top ends and/or bottom ends with respect to each other by means of one or several separate binding pieces. The binding pieces preferably represent a type by means of which there can be created an extension joint at the vertical blank edge. The fastening steps are carried out along with the process of installation of the vertical blanks.

According to an embodiment of the invention, the edge and/or end of the vertical blank is provided with one or several feathers. A feather is advantageous in the installation of a blank. It also is advantageous in the sealing of the structures.

According to an embodiment of the invention, the edge and/or end of the vertical blank is provided with one or several feather grooves. A feather groove is advantageous in the installation of a blank. It also is advantageous in the sealing of the structures. According to an embodiment of the invention, the vertical blank is a vertical beam blank. A vertical beam blank can advantageously be used in the installation of pipes, wires etc.

According to an embodiment of the invention, the wood product also includes at least one horizontal blank with two or several wood blanks that are connected at a mutual distance, so that in between the wood blanks, there is installed one or several connecting pieces. The deformations in this kind of a horizontal blank do not essentially differ from the deformations occurring in the vertical blanks of the wood product. A horizontal blank can advantageously be used in the installation of pipes, wires etc. By combining horizontal and vertical blanks, it is possible to manufacture targets with different surfaces. This is advantageous both architecturally and structurally.

Preferably the horizontal blank includes a wood blank made of plywood or preservative-treated wood. This is particularly advantageous in targets where the structures are subjected to moisture, such as in the plinth structures of exterior walls and in the cornice substructures. It also is advantageous in damp spaces, such as washing facilities etc. This kind of structure also is advantageous for example in a blank located above apertures, when the aperture in question is set lower than normal, and when a vertical blank or blanks are installed above the aperture.

Drawbacks caused in the structures by measure deformations can advantageously be prevented by connecting the vertical blank to the horizontal blank by a bracing, a binding strip, binding plywood or by connecting pins. The drawbacks caused by deformations in these kind of structures can in all directions be prevented extremely effectively. Possible changes in the measures are not multiplied, because the changes in the measures are restricted to one blank only. Preferably the horizontal blank and the vertical blank are connected together, so that they are located at a mutual distance of 5-25 mm.

According to an embodiment of the invention, one or several wood blanks of the vertical blank are preservative-treated and/or surface treated prior to the assembly of the blank, or after the assembly. The preservative treatment or surface treatment is preferably carried out industrially, in industrial conditions, prior to the assembly and installation of the blank. In this way it can be performed in favorable conditions, and the consumption of required materials can be minimized. This reduces expenses and intensifies the technical performance.
