Description

Manufacturing method and device for manufacturing cylindrical structural aggregates {manufactureing method and device for cylinderical glulam}

The present invention relates to a method for manufacturing various circular timbers used in high buildings as structural aggregates, and an apparatus for carrying out the production thereof, and in particular, pillars, beams (girders), softwoods (which are skeletons of high buildings using solid wood) Simple and convenient assembly of a large number of aggregate pieces made of structural aggregates, etc. to produce a single cylindrical columnar structural aggregate, resulting in short-term mass production, cost reduction, and design. As a result, the load is calculated more precisely and precisely, and the strength grade can be measured, and the construction time and cost of the construction are not saved, and there is no shrinkage, heat, decay, deformation, and pest damage after construction, which improves the productability and reliability of the product. To ensure safety of the building after construction and easy and easy maintenance to reduce the cost of follow-up management The present invention relates to a method for producing a molten aggregate and an apparatus thereof.

In general, the traditional Korean architectural style is based on a wooden method based on pure structural mechanics rather than decoration, and is a reasonable tree realized by ancestors through experiences and efforts gained over the years. As a structural technique, it was developed and inherited as a unique wood structure and design that is rare in the Orient.

The wooden building is a natural-friendly building style that can be easily disassembled or regenerated, as well as the mutual coupling of the components. As the wooden building is constructed by combining the unique parts manufactured, it is similar to the prefabrication due to the requirements of industrialization, mass production, standardization, economic feasibility and constructability of the modern society.

On the other hand, the buildings in modern society have the advantages of practical convenience, security, and ease of use by maximizing the residential environment by using various artificial and natural materials such as steel, concrete, and synthetic resin, but modernized people have a weak static part. Each building's architectural style and old buildings are appropriately harmonized with each other, and the newly constructed modern wooden building is preferred. Therefore, various forms of wooden building have unique style and style and are constructed to satisfy the needs of modern people.

The wood used to construct the wood conditional building is selected according to its size and shape according to the purpose of use, so that the members that are the skeletons of the building to be built are subjected to a lot of load, so that the appropriate diameter and strength are calculated. Should be used as essential. However, wood with large diameter and high strength is relatively expensive, cannot be easily supplied, and requires a lot of cost and time for drying and processing, so it is inexpensive, excellent in workability, and manufactured to withstand a lot of load. It is a situation that prefers structural aggregates and actively uses them.

The strength members such as columnar pillar, jumbo, softwood (Rafter) used in traditional Korean wooden structures so far have been dried by large-caliber solid wood in the shade for a long time, and then carved by hand by carpenters. However, this has led to a long preparation period because of the limited selection of materials and the natural drying. In addition, solid wood cannot be completely dried to its interior when it is dried. As the building continues to dry and shrink after completion, severe heat splitting occurs on the surface of the member, and deformation occurs in a part of the building. There was a risk of poor construction that could easily decay and collapse over time, and it was also vulnerable to damage caused by various pests, which shortened the life of the constructed building.

In addition, since the strength grade of the wood itself cannot be measured, and its strength is manufactured based on the carpenter's long experience and practical sense, some of the pillars, which are one of the core members of various cultural assets, etc. Due to the internal and external environment and conditions, nails are often repaired due to shrinkage, heat, decay, deformation, and damage to pests, and the cost of the government is lost.

On the other hand, structural aggregate wood is produced by calculating the exact design and load according to the construction location. Currently, the structural aggregate wood used in domestic and overseas is mainly used in the form of straight type (straight line), and other structural cross-section timber is produced. It is used. Especially in the traditional wooden structure of our country, the curved members of the roof furniture are manufactured by hand by processing the wooden materials with large cross section into the designed curves or by combining the short cut members in several places in order. Low and long-term training and hard work, along with various experiences, are necessary for skilled professional carpenters, as well as inaccurate load calculation during manufacturing, which lowers the reliability of strength and the long manufacturing period, resulting in lower productivity and higher manufacturing costs. There were some flaws.

Therefore, in order to solve the fundamental problems of various member manufacturing techniques used in traditional wood structure buildings, which are constructed depending on the solid wood member as in the prior art, the object is to be devised, the purpose is to manufacture a cylindrical bearing member as a structural aggregate It can compensate for the shortcomings of all wood materials, such as water resistant materials, especially for wood structures exposed to extreme internal / external environments and conditions, and can measure and test the strength grade mechanically. Manufacturing method of cylindrical structural aggregate material that can significantly improve economic efficiency such as manufacturing, construction, and maintenance after construction as it can manufacture large quantity of cylindrical structural aggregates of the same type at a time by freely manufacturing with economic dimensions and securing structural safety. To provide the device.
