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 timber industry market is continuously expanding due to the increase in the use of timber products and the interest in wooden houses due to the improvement of housing and return to homes, the aging culture of low birth rates. According to the recent trend of wood construction, the number of new buildings in 2006 was 4,203 dong, totaling 365,000.

9,585 dong in 2010, total floor area 781,000

At present, more than 10,000 wooden houses are built, with 10,000 wooden houses. In recent years, as the design is diversified and the demand of many owners to build a unique house tends to be considerably longer. Existing structural timber is a reality that the use of aggregate materials, which are engineering wood, is not equipped with structural strength that can withstand the distance.

As shown in FIG. 1, the aggregate 10 is formed by gluing a lumber end plate or an incineration material having a thickness of about 34 mm in parallel with fibers between adjacent laminas 1 in an adhesive direction using an adhesive in a length, width, or thickness direction. Material. Aggregate was developed in earnest after the development of risinol resin, and operating materials began to spread in the 1960s and structural materials in the 1990s. According to the conditions of use, the aggregates are divided into indoor and outdoor use, and there are straight aggregates, curved aggregates, type I cross-section aggregates, upper cross-sections and hollow cross-sections depending on the shape. According to the load direction, it is divided into horizontal laminated aggregate and vertical laminated aggregate, and in Japanese standard JAS, it is divided into operation, structural, and makeup structure according to the use. The grade of adhesive and the appearance of the operating aggregate are the criteria for classifying the grade, and the structural grade is used as a strength member of the building and is used in important places of the structure, so the performance standard is strict.

Structural cross-section aggregates and the characteristics of the building are structurally laminated with lamina, resulting in a material with less variation in strength. As a result, the lower limit of the intensity distribution rises, so that the allowable stress is about 1.5 times the maximum of the lumber. In addition, the raw material of the lamina has a characteristic of less warping and splitting due to the use of a drying material, and a carbonized layer is formed on the combustion part while the surface is ignited and burned, so that the fire resistance is superior to that of ordinary wood.

On the other hand, there is an alternating aggregate (20, Cross Laminated Timber) as shown in Figure 2 as a planar engineered wood formed by laminating orthogonal lamina (1) of the aggregate. Alternating aggregate 20 is an engineered timber with the advantage of being able to construct high-rise wooden building materials. It is a vertically laminated aggregate that has been developed and used in the 2000s in Europe, North America, and Japan. In the United Kingdom and North America, high-level timber constructions are being built using these materials, and the production and scale of the international materials are 475,000m3 as of 2011. Central Europe accounts for about 95% of the total, with production expanding in the UK, Germany and Austria.

However, such a conventional alternating aggregate 20 may cause problems such as twisting and splitting of lamina due to different degrees of shrinkage occurring in each layer when exposed to changes in external conditions such as temperature and humidity. The twisting of the lamina desorbs the adhesive surface between the lamina, and the dry stress caused by the lamina surface and the internal water inclination may cause cracking and splitting on the surface of the alternating aggregate, which may cause deformation by moisture. This can lead to strength degradation which is very unfavorable for use as structural materials. Therefore, it is insufficient to use as a vertical diaphragm in a wooden house.

Accordingly, an object of the present invention is to develop a multi-junction structural aggregate plate that can be used as a vertical diaphragm member in a wooden house to solve the conventional problems.

1) manufacture of the referee 110

The multi-junction structural aggregate plate for the vertical diaphragm member according to the present invention first prepares a small timber that is thinning material for the manufacture of the referee 110. As a thinning timber, a small diameter tree is generally a tree having a diameter of 18 cm or less, and in the present invention, a thinning diameter tree having a diameter of about 120 mm to 140 mm is used. Small tree used in the present invention can be used in all species regardless of species.

Next, the prepared thinning small-sized timber is made of both sides around the depth of water and then rotated 90 degrees to prepare the remaining two sides to prepare a plurality of square materials 111 having a cross-sectional dimension of 80 mm x 80 mm or more. In this case, when the wood is rotated by 90 degrees one by one in order, the small hardwood material has a large amount of immature ghost wood and many growth stresses are present in the interior. Especially in the case of larch, the fiber inclination is large and has a spiral tree, so the torsion is more likely to occur. In addition, in the case of thinning timber, once the sanction on one side and the other side to be sanctioned, the productivity is very low.

Therefore, in order to minimize the occurrence of the torsion during the sanction process and increase the productivity, the two sides facing each other at the same time. In addition, the depth of the small diameter wood is produced with a high density, excellent dimensional stability and excellent strength than the edge, mainly around the water depth.

The prepared corner member 111 is dried at a target moisture content of 15% using a separate drying facility. In the present invention, the cross-sectional dimension of the regular angle member 111 is 80mm or more, which is thicker than the thickness of the commonly used dry wood (50mm), so that it is determined that a drying process different from that of general wood is required. The drying process is applied so that it can dry quickly with the least energy.

The drying process applied to the drying of the shell of the present invention is step 1: steaming for 12 hours at 96 ℃ (steaming); Step 2: high temperature drying for 36 hours at 120 ° C. and 90 ° C. wet bulb temperature; Step 3: medium temperature drying for 24 hours at a dry bulb temperature of 100 ° C. and a wet bulb temperature of 70 ° C .; Step 4: low temperature drying for 24 hours at a dry bulb temperature of 80 ° C. and a wet bulb temperature of 60 ° C .; Step 5: It takes 3 days to cure at room temperature.

Therefore, as described above, after the steaming material is steamed for 12 hours at the initial 96 ° C for 12 hours at a predetermined dry / wet bulb temperature, it is dried for a predetermined time through a high temperature, a medium temperature, and a low temperature drying process such as surface splitting and warping. Drying defects are minimized, and the dryness can be dried as quickly as possible with low energy. Through this drying process, the cornerstone 111 is dried to a target moisture content of 15%.

Then, a slight shrinkage or warping may occur when the drying process is performed. To remove this, the dried right angle member 111 is finished with a planer, and the angle angle member 111 having a length of 2.4 m and a cross-sectional dimension of 80 mm x 80 mm or more is removed. To produce.

Thermosetting resin and thermoplastic resins such as PVAc, PVA, EVA, PUR, epoxy resin, and hot melt and rubber adhesives.

The manufacturing process of plywood proceeds with the process of lumber and capital increase of the wood, the transversal of the wood, the peeling, the cutting of the single board, the drying, the typesetting, the defect repair of the single board, the adhesive application, the cold pressing, the hot pressure and the post-treatment process.

When cutting the end plate, the thickness of the end plate should be 0.5mm or more and 5mm or less. After drying the single plate, the single plate moisture content is dried to 5-10% level, and in the case of coniferous plywood, it is dried to 3-8% water content. The moisture content range of single plate suitable for adhesion should be adjusted according to the type of adhesive used. When using urea and melamine resin adhesives, the water content should be maintained at 5 ~ 15% and phenol resin adhesives at water content below 8%.

Then, in the typesetting process, there may be a number of defects such as splitting, knots, thickening or the like that are smaller than predetermined dimensions in the dried single plate. Small defects scattered here and there are rounded off with a patching machine, then buried in other healthy single plates of the same size and shape, and tapered and repaired. The narrow end plates are made of transverse joints into the desired end plates. Lateral joining is a method in which the sides of the end plates are smoothly cut by a veneer jointer to be in close contact with each other and then taped thereon, or directly bonded by applying an adhesive to the sides of the end plates to be joined. After finishing the repair and transverse joining, the single plate shall be combined with the top plate, the judge, and the second plate in consideration of the construction of the single plate according to the specifications of the product.
