급기야 현재 10,000동이 넘는 목조주택이 들어서, 목조주택 1만 세대이다. 그리고 근래에 들어 설계도가 다양해지고 많은 건축주들의 개성 있는 집을 지으려는 수요가 생기면서 수평부재인 대들보, 장선 등의 길이인 지간거리가 상당히 길어지는 경향이 있다. 기존의 구조용 목재로서는 그 지간거리를 버텨낼 수 있는 구조적 강도가 갖춰지지 않으면서 공학목재인 집성재의 사용이 많아지고 있는 현실이다. Recently, the wood industry market is continuously expanding due to the increase in usage of wood products and the increase in interest in wooden houses due to the spread of high-end housing, return to farming, and low birth rate and aging culture. Looking at the recent trends in wooden construction, the number of new buildings in 2006 was 4,203 with a total floor area of 365,000.

, 2010 9,585 buildings Total floor area 781,000

Finally, more than 10,000 wooden houses have been built, and there are 10,000 wooden houses. In recent years, as design drawings have diversified and many owners have demanded to build unique houses, the length of horizontal members such as girders and joists tends to be considerably longer. It is a reality that the use of laminated wood, which is an engineered wood, is increasing as existing structural wood does not have structural strength that can withstand the span.

As shown in FIG. 1A, the laminated material 10 is laminated by bonding a sawn plate or incineration ash having a thickness of about 20 mm in parallel in the fiber direction between adjacent laminae 1 using an adhesive in the length, width, or thickness direction. It is a material. The glulam was developed in earnest after the development of risorcinol resin, and the glulam for interior use began to spread in the 1960s and for structural use in the 1990s. Depending on the conditions of use, laminated materials are classified into indoor and outdoor use, and depending on the shape, there are straight laminated timber, curved laminated timber, I-shaped cross-section laminated timber, top-shaped cross-section, and hollow cross-section. Depending on the load direction, it is divided into horizontally laminated laminated material and vertical laminated laminated material. According to the Japanese standard JAS, it is classified into interior, decorative interior, structural, and decorative structural use according to the purpose. The degree of adhesion and appearance of laminated materials for interior use are the standards for class classification, and laminated materials for structural use are used as strength members in construction and are used in important structural areas, so performance standards are strict.

As for the characteristics of structural single-sided laminated materials and their buildings, materials with less variation in strength are obtained by intentionally laminating lamina, and as a result, the lower limit of the strength distribution rises, so the maximum allowable stress is about 1.5 times that of the material. In addition, since the raw material of lamina uses dry material, it has characteristics of less distortion and splitting, and a carbonized layer is formed on the burned part while the surface is ignited and burned, so the fire resistance performance is superior to that of general wood.

On the other hand, among the laminated materials, there is a cross laminated timber (20, Cross Laminated Timber) as shown in FIG. Gyoho laminated wood (20) is an engineered wood that has the advantage of being able to construct high-rise wooden buildings, and is a laminated wood of a vertically laminated structure developed and used in the 2000s in Europe, North America, and Japan. In the UK and North America, high-rise wooden buildings are being built using these laminated timbers, and the production and scale of the laminated timbers around the world is 700,000㎥ as of 2017. Among them, Central Europe accounts for about 95%, and the market is expected to expand to about 1,000,000 m3 in 2018 with production expansion in the UK, Germany and Austria.

However, when such a conventional cross-laminated material 20 is exposed to changes in external conditions such as temperature and humidity, problems such as twisting and splitting of lamina may occur due to different degrees of shrinkage occurring in each layer. The twist of the lamina detaches the adhesive surface between the laminas, and the drying stress caused by the lamina surface and the internal moisture gradient causes cracks and splits on the surface of the alternate laminated material, which can cause deformation due to moisture. This can cause a very unfavorable decrease in strength for use as a structural material. In addition, since cross-laminated timber is a relatively new engineered wood, its moisture characteristics are not properly evaluated, and when an alternate laminate that is not protected from precipitation is exposed to high moisture conditions for a long time, deterioration may occur due to moisture or rot.

Therefore, in order to solve the problems of the conventional laminate and alternate laminate, the present applicant proposes a hybrid laminate and a manufacturing method thereof (Registration Patent No. 10-1462013, published on November 19, 2014). In the above patent, as shown in FIG. 2, lumber is prepared by sawing raw wood to a predetermined width and thickness, drying the prepared lamina to have a predetermined moisture content, and then bonding the dried lamina with an adhesive in the longitudinal direction to a predetermined A laminated board 30 having a certain length and width is manufactured through length joining or side joining in the width direction so that the length of A core layer including one plywood (40, 41) formed by stacking the above odd-numbered sheets and bonding with an adhesive is manufactured, and the laminated board 30 manufactured on the upper and lower sides of the core layer is bonded as a surface layer and a double layer with an adhesive.

However, the laminated material presented in the above patent also suffers from a problem of being vulnerable to heat insulation or fire due to its basic characteristics made of wood.

Three or more veneer single plates 2110 are placed on top of the center layer 1000 made of laminated plates having a certain length and width through side joining to have a predetermined width by being joined in a direction so as to be parallel or orthogonal to the fiber direction. bonding the surface plywood layer 2100 made of plywood bonded with; And combining a back plywood layer 2200 made of three or more plywood bonded so that a plurality of veneer veneers 2110 are parallel or orthogonal to the fiber direction under the center layer 1000.

Hereinafter, each step is described in more detail.

First, in the first embodiment, a laminated board forming the central layer 1000 of a multifunctional hybrid laminate for construction is manufactured. The production of the laminated board is carried out in the order of drying of lamina, length bonding and longitudinal bonding, bonding and finishing processes. The lamina used in the laminated board manufacturing step is generally pine, black pine, larch, Douglas pine, cypress, cedar, fir, hemlock, spruce, dogwood, Japanese hemlock pine, spruce and radiata pine, including domestic materials, Conifers such as Douglas fir and hemlock, and domestic hardwoods such as beech, birch, zelkova, ash tree, quercus oak, red oak, oyster oak, cedar, chestnut, water oak, maple, and elm, and apiton , Black locust, Nawang, Eucalyptus, Acacia, Albizia, and Jabong are used. The standard of lamina used for laminated materials is a standard of 3 mm or more and 100 mm or less in thickness, 1 cm or more in width, and 10 cm or more in length.

The prepared lamina is dried to a predetermined moisture content using a separate drying facility. At this time, the moisture content of the lamina after drying is appropriate to be 8 to 15%, and 8 to 12% for indoor laminated materials and 12 to 15% for outdoor laminated materials are preferable. In addition, the difference in moisture content between adjacent laminas should be within 3%, and the difference in moisture content between all laminas should be uniform within 5%. After drying, the sawn lamina goes through a process of processing with an industrial planer to generally equalize the thickness of the sawn board.

The refined cut lamina is then subjected to longitudinal bonding and side bonding after removing defects that deteriorate adhesive strength and appearance with a transverse saw or patcher. Adhesives used at this time include thermosetting resins such as phenol, melamine, urea, and isocyanate-based, thermoplastic resins such as PVAc, PVA, EVA, PUR, and epoxy resins, and hot-melt and rubber-based adhesives.

Side bonding refers to a process of bonding narrow lumber boards in the width direction to a predetermined width, and is bonded using a butt joint and tongue groove bonding method having a strength effectiveness of 90% or more.

Length joining refers to a process of joining sawn boards in the longitudinal direction to have a predetermined length, and the type of length joining is selectively performed by butt joint, scarf joint, finger joint, and the like.

In this way, the assembled plate 100 having a certain length and width is manufactured through length bonding or side bonding. The manufactured laminated board 100 is cut to a predetermined size using a double sizer in which two sets of circular saws are combined, and surface finishing is performed by adjusting the thickness and smoothing the surface through surface polishing. . Surface polishing is removed by sanding a thickness of 0.25 to 0.5 mm using a wide belt sander or the like.

Next, manufacturing of the front plywood layer 2100 and the back plywood layer 2200 will be described. The species used for the plywood constituting the surface plywood layer 2100 and the back plywood layer 2200 include domestic materials such as larch, regida pine, deciduous pine, white pine, birch, chestnut, pine, cypress, cedar, and radiator pine. , imported conifers such as Japanese cedar, cypress, Douglas fir and hemlock from North America, and larch from Russia, as well as eucalyptus, meranti, MLH (mixed local hardwood), poplar, acacia, radiata pine, KERUING, albizia, and jabong. Mixed species of Namyangjae broad-leaved trees with the same afforestation properties.

The plywood manufacturing process consists of boiling and increasing treatment of logs, transverse cutting of logs, peeling, cutting of veneers, drying, typesetting, repair of defects in veneers, application of adhesive, cold pressure, hot pressure, and post-treatment processes.

The veneer veneer 2110 is manufactured using a rotary race, and the veneer 2110 has a thickness of 0.5 mm or more and 5 mm or less during cutting. After drying the veneer, the veneer moisture content is dried to a level of 5 to 10%, and in the case of softwood plywood, the moisture content is dried to a level of 3 to 8%.

Then, in the typesetting process, among the dried single plates, there may be a plurality of those having defects such as cracks, knots, and decay, or smaller than a predetermined size. Small defects scattered here and there are circularly removed with a patching machine, then patched with another sound veneer of the same size and shape, and veneer with cracks is repaired by taping. A narrow veneer is made into a veneer of the desired width through transverse bonding. For transverse bonding, there is a method of smoothly cutting the side surfaces of veneers with a veneer jointer to bring them into close contact with each other, then taping them thereon, or directly bonding by applying an adhesive to the side surfaces of veneers to be joined. Veneers that have been repaired and transversely joined are combined with face plates, referees, and backings in consideration of the configuration of veneers according to product specifications.

After drying the veneer veneer 2110 prepared as described above, it is manufactured by laminating using a thermosetting resin and an amino-based resin adhesive. Adhesives used in the manufacture of plywood include phenol resins, urea resins, melamine resins, epoxy resins, polyurethanes, and the like.

In plywood, the number of veneer stacks must be at least 3ply, and the thickness of veneer must be between 0.5mm and 5mm, and the total thickness of plywood must be 2.4mm, 2.7mm, 3.6mm, 4.8mm, 5.2mm, 6mm, 7mm, 9mm, 11.5mm, 12mm, 15mm, 18mm, 22mm, 24mm, 30mm, 40mm, 50mm, etc., including the standards set by international standards for plywood. Unlike conventional plywood lamination, the plywood to be laminated may be alternately laminated using only core veneers having a constant thickness without distinguishing between the front and back surfaces (Face, Back).

After manufacturing the front plywood layer 2100 and the back plywood layer 2200 with such plywood, the front plywood layer 2100 is bonded to the upper part of the center layer 1000 with an adhesive centering on the previously prepared center layer 1000. Then, the back plywood layer 2200 is bonded to the lower part of the center layer 1000 with an adhesive to manufacture the hybrid laminate according to the present embodiment.

In plywood, the fiber direction of the upper and lower veneer veneer 2110 may be cross-laminated with the laminated board constituting the center layer 1000, and the fiber direction of the middle veneer veneer 2110 may be combined with the plywood parallel to the laminated board. It can be.

The front plywood layer 2100 and the back plywood layer 2200 are joined to have the same width and length as the center layer 1000, respectively.

The produced hybrid laminate is cut to a predetermined size using a double sizer that combines two sets of circular saws, and surface finishing is performed by adjusting the thickness and smoothing the surface through surface polishing. Surface polishing is removed by sanding a thickness of 0.25 to 0.5 mm using a wide belt sander or the like.

The hybrid laminate of the present invention manufactured in this way is prepared by bonding the front plywood layer 2100 to the upper surface of the center layer 1000 and bonding the back plywood layer 2200 to the lower part of the center layer, so that it is different from the conventional laminate. Compared to alternately laminated materials, it is possible to improve the bending strength and modulus of elasticity due to the relatively dimensional stability and thin plate multi-layer bonding structure.

Incidentally, in the case of domestic materials, a large-area veneer cut from a small-diameter log of less than 50 cm is used, so it is possible to manufacture a plate product with a wider area than that of felled logs, so that wood resources are efficiently used, and veneer is mutually Due to orthogonal lamination, dimensional and strength anisotropy can be improved.

Next, a method for manufacturing a multifunctional hybrid laminate for construction according to a second embodiment of the present invention will be described. In the multifunctional hybrid laminate for construction according to the second embodiment of the present invention, the plywood constituting the surface plywood layer 2100 and the back plywood layer 2200 is different from that of the first embodiment.

In this embodiment, the plywood 210 is manufactured by laminating the veneer veneer 2110 impregnated by injecting an impregnation resin into the veneer veneer 2110.
