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 an increase in the use of wood products and an increase in interest in wooden houses due to the spread of high-grade housing, return to farming, and low birthrate and aging culture. Looking at the recent trend of wooden construction, the number of new buildings in 2006 was 4,203, and the total floor area was 365,000.

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

In the end, more than 10,000 wooden houses have been built so far, and there are 10,000 wooden houses. And in recent years, as the design drawings have been diversified and the demand for building individual houses from many clients has arisen, the span distance, which is the length of horizontal members such as girders and joists, tends to become considerably longer. The reality is that the use of laminated wood, an engineered wood, is increasing as the existing structural wood does not have the structural strength to withstand the span.

As shown in Fig. 1, the gluing material 10 is laminated by using an adhesive in the length, width, or thickness direction by paralleling the cutting board or incineration material with a thickness of about 34 mm in the fiber direction between adjacent laminas 1. is the material Laminate materials were developed in earnest after the development of risorcinol resin, and fabrication materials began to be distributed in the 1960s and structural materials in the 1990s. Laminates are used for indoor and outdoor use according to the conditions of use. According to the shape, there are straight-woven laminates, curved laminates, I-section laminates, upper-type cross-sections, and hollow cross-sections. According to the load direction, it is divided into horizontal laminated laminates and vertical laminated laminates, and in the Japanese standard JAS, it is divided into operational, structural, and decorative construction according to the use. For gluing materials for operation, the degree of adhesion and appearance are the criteria for classification, and since gluing for structural use is used as a structural strength member and is used for structurally important places, the performance standards are strict.

As for the characteristics of structural large-section laminates and their buildings, a material with less variation in strength is obtained by deliberately laminating lamina, and as a result, the lower limit of the strength distribution rises, so the allowable stress is up to about 1.5 times that of the material. In addition, since the raw material of lamina uses a drying material, it has less warping and splitting characteristics, and a carbonized layer is formed in the combustion part as the surface ignites and burns, so the fire resistance performance is superior to that of general wood.

On the other hand, there is a structural laminated board 20 (Cross Laminated Timber) as shown in FIG. 2 as a plate-shaped engineered wood constructed by laminating lamina 1 orthogonally among the laminated materials. The structural laminate 20 is an engineered timber having the advantage of being able to construct a high-rise wooden building, and is a laminate of a vertical laminate structure developed and used in Europe, North America, and Japan in the 2000s. In the UK and North America, high-rise wooden buildings are being constructed using these structural laminates, and the global production and scale of structural laminates is 475,000㎥ as of 2011. Among them, Central Europe accounts for about 95%, and production is increasing in the UK, Germany and Austria.

However, when the conventional structural aggregation plate 20 is exposed to changes in external conditions such as temperature and humidity, problems such as twisting and splitting of the lamina may occur due to different degrees of shrinkage occurring in each layer. The torsion of the lamina detaches the adhesive surface between the laminaes, and the drying stress caused by the lamina surface and the internal moisture gradient can cause cracks and splits on the surface of the structural aggregation plate, which can cause deformation due to moisture. This may cause a very unfavorable decrease in strength for use as a structural material. In addition, the structural laminated board uses an excessive amount of wood because the entire volume of the wall is filled with wood, and in countries with scarce wood resources such as Korea, there are many restrictions on practical use and industrialization due to problems such as resource shortage and increased manufacturing cost. . In addition, as an absolute factor in which energy consumption reduction and energy efficiency improvement must be realized in future buildings, structural laminates have only half the insulation performance of wood itself than insulation materials. It has the disadvantage that the performance cannot be satisfied.

Therefore, the present invention solves the problems of the prior art and achieves the purposes of excellent structural performance, minimization of defects in wood and drying defects, reduction of manufacturing cost, improvement of energy efficiency, etc. It aims to develop a vertical diaphragm member.
