Description

Joint member for wooden module and wooden module structure using the same {Joint Member for Connecting Wooden Construction Modules And Wooden Construction Module Having the Same}

The present invention relates to a device for connecting a plurality of wooden modules, and more specifically, it is possible to implement a wooden module structure in a desired shape by stacking and connecting columns or beams of a plurality of wooden modules made of a plurality of column-beams side by side. It relates to a joint device for a wooden module.

The modular system is an innovative method of manufacturing modules in the factory and assembling unit modules in the field. Because it is manufactured by dry method, it is possible to construct all weather, and it is easy to reuse resources and expand and rebuild using unit modules.

Although the existing modular system is mainly made of steel, the interest of buildings using wood is increasing due to carbon reduction and development and distribution of various engineering wood. In addition, the cost of the steel modular system is about 125% compared to the RC frame, which has a disadvantage in economic efficiency. Currently, Korea needs to promote the demand of wood as a thinning season, and it is also necessary to develop and disseminate wood-related technologies in order to develop a demand for wood using wood modules.

The wooden module is made of a wooden module structure of a rectangular parallelepiped by connecting a plurality of pillars and beams to each other. In order to make a structure having a desired structure using the wooden module, it is necessary to connect a plurality of wooden modules to each other.

However, conventionally, the joint structure for connecting the wooden pillars and beams to each other is suitable for individually connecting the pillars and the pillars, or the pillars and the beams, the beams and the beams, but stacking the pillars and beams of a plurality of wood modules already made side by side. It is not suitable for connection.

For example, in Patent Publication No. 10-2009-0112983, a T-shaped steel having a web and a flange in a T-shape or an H-shaped steel having a web and a flange in a H-shape can be fitted into a slit formed at the end of a wood member to be joined. A "joint structure of a wooden member" is disclosed.

This prior art joining structure is a structure in which a pillar and a beam made of a wooden member can be directly connected to a joint structure made of H-beam or T-beam, suitable for constructing a single wooden module by connecting a beam and a beam, but already made It has a structure in which the pillars or beams of one wooden module are stacked side by side with the pillars or beams of another wooden module, and are difficult to join.

Republic of Korea Patent Publication No. 10-2009-0112983 (2009.10.29. Public) Republic of Korea Registered Patent No. 10-1906499 (Registration on October 2, 2018) Republic of Korea Registered Patent No. 10-1639256 (Registration on July 07, 2016)
