Definitions
- the present invention relates to a construction structure for building members, in which each construction member constituting a frame of a wooden building is bonded and reinforced by using a fiber sheet as a joining main material.
- this type of joint has the problem of corrosion due to salt damage, etc., and the condensation of the walls caused by heat bridges causes rot of the wood, degradation of the performance of the heat insulating material, and heat insulation defects. Yes.
- the technology of bonding and bonding fibers to building components of buildings is being considered.
- the tensile strength which is a characteristic of fibers, can be obtained simply by cutting the fibers, bending them, and sticking them.
- the toughness could not be fully utilized, and it was difficult to make a reliable contact.
- Fiber reinforcement technologies include reinforcement of reinforcing bars such as public roads, railway viaduct columns, reinforced concrete building columns, beams, slabs, walls, tunnel inner walls, etc.
- fiber is actively used for seismic reinforcement work.
- it has not been used for wooden buildings.
- the present invention has been made in view of the above circumstances, and makes use of the characteristics of the strength neodymium made of a fiber in which a high tensile strength fiber such as aramid fiber, carbon fiber, or glass fiber is formed into a sheet shape. Instead, it is used together with an adhesive as the main material for bonding, and it provides a highly reliable building member bonding structure that can be bonded and reinforced at a very low cost with flat construction. The purpose is that. Disclosure of the invention
- the present invention is a joining structure of building materials for joining building members constituting a frame of a wooden building, and has a sheet-like fiber having a high tensile strength straddling the joining portion on the surface of the building members.
