Description

내진용 보강구{ASEISMATIC REINFORCING DEVICE}Earthquake-resistant reinforcement {ASEISMATIC REINFORCING DEVICE}

본 발명은 지진, 태풍 등에 의해 목조 건축물에 심한 진동이 가해져도 붕괴되지 않도록, 교차하여 접합되어 있는 건축 구조재의 상호간에 걸쳐 설치함으로써 그 진동에 대한 내성을 보강하는 것을 목적으로 하는 내진용 보강구에 관한 것이다.The present invention is to provide a seismic reinforcement for the purpose of reinforcing the resistance to the vibration by installing over the mutually joined building structural members so as not to collapse even if severe vibration is applied to the wooden building due to earthquake, typhoon, etc. It is about.

종래, 목조 건축물 구조재의 접합부를 보강하는 방법으로서 브레이스(brace)나 앵글 브레이스(angle brace)를 설치하거나, 클램프, L형 기구를 부착하거나 하는 등 다양한 방법이 채용되어 왔다.Conventionally, various methods, such as providing a brace or an angle brace, attaching a clamp, or an L-shaped mechanism, have been adopted as a method of reinforcing a joint of a wooden building structural member.

그러나, 상기와 같은 방법에서는, 지진, 태풍 등에 의해 심한 진동이 가해졌을 경우의 보강 효과가 충분치 않았으며, 접합부에서 건축 구조재가 이탈되거나 파손되고 심할 경우에는 목조 건축물이 무너지는 경우도 있었다.However, in the above method, the reinforcing effect when severe vibration was applied by an earthquake, typhoon, etc. was not sufficient, and in some cases, the wooden structure collapsed when the building structural material was detached or damaged at the joint.

가령, 일본국 특허공개 공보 제1997-144135호에 개시되어 있는 건축용 보강구는, 도 6의 사시도로 나타낸 바와 같이, 복수의 네일링 홀(nailing hole ; 61) 및 볼트 홀(63)을 가지는 장방형으로 접힌 형상의 철판(6A)에 철골부재(62)를 걸쳐 설치한 것이다.For example, the building reinforcement disclosed in Japanese Unexamined Patent Publication No. 1997-144135 has a rectangular shape having a plurality of nailing holes 61 and bolt holes 63 as shown in the perspective view of FIG. 6. The steel frame member 62 is provided on the folded steel plate 6A.

상기 건축용 보강구에서는, 기둥 구조재와 들보 구조재를 서로 견고히 접속시키는 효과는 기대할 수 있으나, 그 구성상, 완충성 및 스프링 탄발성이 부족하기 때문에, 지진, 태풍 등으로 인해 목조 건축물에 수직 방향이나 수평 방향에 대한 진동, 연직 회전의 요동이 가해진 경우에는 응력이 집중되는 보강구의 부착 부위가 파손되기 쉽다는 문제가 있다.In the building reinforcement, the effect of firmly connecting the pillar structure and the beam structure to each other can be expected, but because of its lack of cushioning and spring elasticity in the construction, due to earthquakes, typhoons, etc. When vibration in the direction and fluctuation of the vertical rotation are applied, there is a problem that the attachment portion of the reinforcing tool where the stress is concentrated tends to be broken.

본 발명은 이러한 문제점을 해결하도록 이루어진 것으로서, 지진, 태풍 등으로 인해 목조 건축물에 강력한 진동이 가해져도 붕괴되지 않도록, 교차하는 건축 구조재의 상호간에 걸쳐 완충성, 스프링 탄성을 구비한 보강구를 강력히 부착함으로써 진동에 대한 내성을 향상시키도록 한 내진용 보강구를 제공함을 목적으로 한다.The present invention has been made to solve this problem, it is strongly attached to the reinforcement having a cushioning, spring elasticity between the cross of building structural materials so as not to collapse even if a strong vibration is applied to the wooden building due to earthquakes, typhoons, etc. It is an object of the present invention to provide a seismic reinforcing tool for improving resistance to vibration.
