FIELD OF THE INVENTION

The present invention relates to a wood structure! thick-gauge countershaped and a prefabricated building element comprising, a piece or segment of a structural wood, coni-plywood of thick caliber, which has dimensional stability and structural strength, useful for building wooden buildings, and the manufacturing methods thereof .

BACKGROUND

There is no set of ready-to-assemble prefabricated building elements on the market, useful for building wooden buildings, because the wood contracts and expands depending on the humidity. The natural movement of the wood, measured by the contraction coefficient, prevents the processed wood that is currently sold from incorporating measures intended to be used on site, because the variation in environmental humidity affects these measures.

It is proposed to use the plywood technique to make gray structural wood © caliber through the use of wood layers with a thickness much greater than the maximum that can be obtained with the currently known debinding techniques; to do this, the tulips, or layers of conventional debolinated wood, which are up to 4 6 5 mm thick, are replaced by solid wood boards known as finger joini that are 16 to 80 mm thick.

The so-called finger joini boards are plates composed of small pieces of solid wood adhered together by the front through a collection mechanism known as finger joim and glue edge. In said boards, the pieces of wood adhered to each other have the direction of the fiber oriented in the same direction and, therefore, behave from the point of my mechanical physique as a thick-gauge tulip, impossible to obtain with the debinding techniques existing today. The plywood boards are partially affected by the characteristic natural movement of the wood, because they are composed of layers of spruce wood arranged between them, so that the orientation of the fiber is perpendicular between one layer and the next, thereby canceling the movements of the wood and providing dimensional stability in two of its three dimensions, identified as length and width, so that only the thickness is affected by the natural movement of the wood, which for a pine board of 15 nirn Thickness is of the order of the hundredth of a millimeter, negligible magnitude to the scale of the measures with which said material is used in the current furniture and construction industry, in applications such as molding and coating.

In the market there are construction elements called laminated wood of the structural beam type, used to cover large lights. Said curved or straight beams are manufactured with small piece or slats of solid wood joined together by a coupling mechanism known as finger joint and are glued by the spine and pressed giving logar to a piece of solid wood in which the direction of the wood fiber is oriented in the same direction and therefore said piece of wood is flexible and is subject to dimensional instability since it is affected by the natural movement of the wood.

Laminated wood beams have my advantage of ecological connotation; In addition to being a renewable product, it is the construction material that uses less energy in industrial transformation processes. This advantage also applies to the present invention, since the transformation of the wood log into a pillar or beam involves known processes and technologies.

In the field of wooden structures, works with timber are known, from the old cabinetmaking to the current boards. The composition of wood solids made with laminated layers stands out, where the fiber direction is alternated successively between one layer and the next, since it generates more resistant wood than similar pieces of solid wood.

On the other hand, in the state of the art there are publications that disclose plywood made with ^' finger pint ^' boards as a dimensional stabilizer of wood. CN publication 101913174, entitled "Structured wood of small restructured diameter and lubrication technology", refers to the manufacture of structural wood made from wooden bundles obtained from tree logs with diameters between 5 and 10, that is, waste, with which units from 180 to 300 mm long are made by known procedures ;, to which it incorporates a coupling mechanism of the type finger joint or of iggete through which they join with other similar units giving rise to a ribbon , which can be used to make a beam. In this case the slats that make up the beams have the wooden beams located parallel to each other, so that the direction of the fiber is in the same direction and therefore affected by dimensional instability.

CN publication 1017691 17, entitled "Wood composite door manufacturing method", describes a process for manufacturing a door composed of an outer frame, a filled inner frame where said frame is made up of parts assembled through a mechanism of union with form of T able to couple them of perpendicular way. The filling consists of units made of a plywood composed of three layers of solid wood pieces joined by the front through a finger joint type coupling mechanism, a composition that would be responsible for providing dimensional stability and thus prevent deformation.

CN publication 201818204, entitled "Plate and frame for wooden door composed of solid anti-debris wood", describes a plate and frame of anti-deformation door composed of solid wood, comprising a top finger joint panel, a panel middle finger joint and a lower finger joint panel, in which the upper and lower panel are respectively formed by the connection of two or more panels arranged laterally; the central panel is formed by the connection of two or more longitudinally arranged panels; The peripheral sizes of the upper, middle and lower panels are consistent, and the upper, middle and lower panels are laminated together and fixed by using panel glue. This plate and anti-deformation door frame composed of solid wood is formed by laminate and fixed connection of three or more of three layers of panels, in order to achieve the purpose of preventing the plate and door frame from being warped. distorted.

The teachings contained in the aforementioned publications CN 1017691 17 and CN 201818204 refer to the use of plywood made with solid wood boards of the finger joint type, generating a thick gauge plywood that is dimensionally stable. However, in such publications, thick gauge plywood is used as a dimensional stabilizer or argon-detonation, in a product such as when used, used in the. housing construction that is not subject to structural efforts.

In the present invention, in. On the other hand, the pieces or segments of heavy-gauge structural countertop wood are occupied as pillars and structural beams used in the construction of wooden buildings and, therefore, subject to considerable tensile and compressive stresses, for example, in case of eventuality. of a seismic event.

One of the objectives of the present invention is to find a solution to the problem of dimensional instability and deformation of wood using an implicit quality in thick gauge plywood, which is to adequately support structural requirements when used in a certain way, such as for example in pillars and beams for wooden buildings, with the result that they are less flexible and more stable; unlike the use as a dimensional stabilizer revealed in the cited documents of the prior art.

More parüculannente, unlike! Conventional plywood, which is made from wood with a thickness of up to 5 MI and provides pieces up to 25 mm thick, the solution proposed in the present invention lies in. the size of the pieces that can be obtained, as well as in their structural strength and dimensional stability, and consists of the elaboration of a plywood with solid wood of the finger join board type with thicknesses from about 5 mm to about 200 mm, which they generate pieces from about 15 mm to about 1, 000 mm, to be used in large structures.

SUMMARY OF THE INVENTION

A structural Mader contraehapada caliber, which has dimensional stability and structural strength, comprising at least me first layer comprising at least one first board solid wood UPO finger j rni whose thickness may vary between about 5 described up to about 200 mm, comprising pieces of wood adhered together that have the direction of the fiber oriented in the same direction; at least a second layer, which comprises at least a second solid wood board of the fi gerjoini type, whose thickness it can vary between about 5 to about 200 mra, comprising pieces of wood adhered to each other that have the direction of the fiber oriented in the same direction; wherein said first layer and second layers are superimposed so that the direction of the fiber of the first layer is perpendicular to the direction of the fiber of the second layer, said layers being glued and pressed to form a structural plywood thickness caliber.

DETAILED DESCRIPTION OF THE INVENTION

A structural wood is described, with thick caliper veneer, in which the plywood technique is used, replacing the layers of conventional rusty wood, which are up to 4 or 5 mm thick, with a solid wood board of the finge r type. jomí, which are from about 5 to about 200 inm thick, and preferably from about 16 to about 80 mm thick, where the pieces of wood adhered to each other have the direction of the fiber oriented therein sense and therefore behave from a mechanical physical point of view like a thick gauge tulip, i u

With said boards called finger joini, a solid structural plywood composed of two or more glued and pressed layers of boards of! type pretends r joint where the direction of the fiber of a layer is perpendicular to the direction of the ñbra of the adjacent layer. This results in a thick-gauge structural plywood that has dimensional stability in two of its three dimensions.

Said thick gauge structural plywood can be cut to obtain smaller pieces with the particular shape desired. It is particularly relevant to obtain pieces of square or rectangular section, because they can be properly used as pillars and beams in the construction of wooden buildings, as can be established by analyzing their structural characteristics.

Figures 1 a, Ib and illustrate an preferred embodiment, where a single beam (10), is made from structural plywood of thick caliber. The beam (10) comprises 5 layers (1 1.-15). where each layer comprises a finger joini board. As can be seen in Figure Ib, the layer (1 1) of the beam (10) comprises pieces of wood (16), adhered together, with the direction of the fiber oriented in the same direction. On the other hand, the layer (12) comprises pieces of wood (17), where the ñbra is oriented perpendicular to the direction of the pound of the layers immediately adjacent to it, that is, to the direction of the ñbra of the layers (11) and (13).

The structural plywood can also be cut to make parts of more complex pillars and beams, such as a beam with a double T profile, as shown in Figures 2 to 5,

Figures 2a. 2b and 2c illustrate another preferred embodiment, where a beam (100), with a double T profile, is made of three parts, each being equivalent to a single beam (10). Figures 3 to 5 show profile drawings, plan and elevation of said beam (100) with double T profile. In this beam (100), both the core and its parallel parts are pieces of thick plywood structural wood. caliber; This variant allows to optimize the occupation of material in pillars and beams by providing units that have a square or rectangular perimeter section and a double T profile. one !

In Figures 2b. 4 and 5 it can be seen that the g (100) includes coupling mechanisms with other construction elements such as the head of said corrugated beam for coupling with a double T-type pillar, or the perforations (110) and ( 120), imi tormera spaced along the parallel parts of the beam (100). The perforations (1 10) pass through the upper part of the parallel parts, passing through some of the layers of said upper part, and fulfill the function of fixing components of a wall by means of shafts. The perforations (120) longitudinally cross the parallel parts of the beam (100) longitudinally, and fulfill the function, of fixing component construction elements by means of shafts. mezzanine

Because the plywood of thick caliber is dimensionally stable in two of its three dimensions, said dimensional stability remains in the pieces or segments thereof and, therefore, in the structural beams and pillars formed from the plywood of Thick caliber of the present invention. The dimension affected by dimensional instability, the caliber, compromises the width of a solid beam or pillar, the magnitude of the distortion of said measure being of the order of the tenth of a millimeter, negligible amount at the scale of said construction elements. In the case of a beam or pillar with a double T profile, the measurement distortion affects the width of a pillar and the height of a beam with the same order of magnitude for elements 150 mm wide and 400 mm high respectively.

In this way, by means of the present invention, it is possible to make plywood construction elements of thick caliber, such as pillars and structural beams, with pre-established measures that are not altered. Significantly due to variations in ambient humidity, and therefore, they provide prefabricated building elements suitable for work-related work without the need to intervene in the factory measures, which, when assembled together, give rise to rigid frames that are components of rigid structures that can be used in buildings intended for example for housing or residential use.

A bounded set of construction elements with. Modular measures of the pillar and beam type are capable of constructing any architecture that is the result of repeating and grouping the modular mother unit of said modular measures, so that the design versatility will depend of the amount of said modular unit; to a lesser extent, greater precision is obtained in the architectural design and a greater variety of construction elements is used, and vice versa.

ADVANTAGES OF THE INVENTION

The present invention provides structural advantages. The prefabricated construction elements made from the thick gauge plywood structural wood in the form of pillars and beams, can be used as structural construction elements because of the good performance they offer when they are subjected to tensile and compression stresses.

The direction of the fibers of the wood between one layer and the next in the structural plywood forms an angle of 90 °. The angle of attack of a load is 45 ", with respect to the horizontal or vertical of the beam or the pillar, that is to say, symmetrical with respect to the angle of 90 ° in which the fibers of said beams or pillars of structural plywood are located. when they are located perpendicular or parallel to the floor as the pillars and beams are used respectively, and therefore, the load affects the fiber in the same way one way and the load is distributed equally.

The invention also provides dimensional stability. Conventional wooden beams and pillars are made at the time they are going to be occupied because, as we have said, the wood moves.

On the other hand, in the prefabricated construction elements made with the structural plywood of the present invention, the wood is stabilized by the effect of the plywood, and therefore, the construction elements can be prefabricated, made with measures and shape that. they are altered or deformed, so that it is possible to offer a set of pillars and beams with complementary coupling mechanisms, in order for trailers to achieve a rigid structure capable of being occupied in a wooden building, for example for use hahíiacíonai.

Conventional beams and laminated wooden beams of the prior art that are affirmed by the ends are deformed with a downward curve, due to the effect of gravity, which entails two difficulties: one refers to the deformation itself which results in that the ground clearance at the middle of the beam is less than at the ends and therefore any partition that is incorporated between pillars and beams will have to be tailored to the deformation; the other difficulty refers to the fact that the proper weight and the loads of the beam are transmitted to said partition. On the contrary, the beams constructed with the coutraehapada structural wood according to the present invention do not suffer deformations, because their internal structure prevents deformation and by tamo, it does not cause the difficulties of the laminated beams.

On the other hand, a beam with a double T profile constructed with the erased structural wood according to the present invention, such as for example the practical embodiment described in Figure 2, optimizes the resistance with respect to the thickness of the material with which it is made. , in the case of a beam made of heavy gauge plywood, where the core of the beam can be distinguished, consisting of the central piece, and the parallel pieces of the beam. The thickness of the pieces can be adjusted to different requirements, such as making the resistance ratio versus the amount of material used optimal, or to give special characteristics to the beam, such as greater or lesser flexibility.

In addition, the present invention provides manufacturing advantages. The way to manufacture the conventional laminated beams is from pieces of solid wood with a standardized width that are joined by the front through a union of the fmger join type those that adhered, glued and pressed by the spine generates a laminated beam that It can be as long as there is capacity to transport it. On the contrary, the beams of the present invention are manufactured from solid wood boards of the finger join type known in. the local branch market as "MasíerPiac®"; so that there has already been a long process of wood and the maximum measures of a board, which are around 1 x 6.5 meters, are dimensions suitable for manufacturing pillars and beams intended for use in homes. The use of a suitable glue is also contemplated to resist elect weathering.

The present invention also provides design versatility. In one embodiment of the present invention there is a bounded set of pillars and beams made from thick-gauge eontrachapated wood of the present invention that differ from each other by modular measures, serve to design and build any building with an architecture that uses Í4 as a module of composition of measures the. core unit of these modular measures.

The present invention further provides a clean construction. The constructive task associated with the use of the construction elements contemplated in the invention does not produce annoying noises; leaves no residue; It can be done between two people, therefore the weight of the pillars and beams is suitable to be handled and transported by said equipment; It is quick to execute, because the constriction elements incorporate coupling mechanisms ready to assemble and therefore have predefined the assembly of the pieces, which are fixed to each other through metal fittings.
