Description

내진 보강 기구 {ASEISMATIC REINFORCING DEVICE}Earthquake-resistant reinforcement mechanism {ASEISMATIC REINFORCING DEVICE}

본 발명은, 지진, 태풍 등에 의해 강한 진동이 부하되어도 목조 건축물이 붕괴되지 않도록, 토대, 기둥, 도리, 보 등의 구조재의 접합부에 부착하여 보강하는 내진 보강 기구에 관한 것이다.The present invention relates to an earthquake-resistant reinforcement mechanism for attaching and reinforcing a joint part of a structural material such as a foundation, a pillar, a purlin, or a beam so that a wooden building does not collapse even when a strong vibration is applied by an earthquake, typhoon, or the like.

종래, 목조 건축물의 구조재의 접합부를 보강하는 방법으로서는, 브레이스(brace)나 앵글 브레이스 빔(angle brace beam)을 설치하거나, 꺾쇠(clamp), L형 기구를 부착하는 등, 여러 가지 방법이 채용되었다.Conventionally, as a method of reinforcing a joint of a structural member of a wooden building, various methods have been adopted, such as providing a brace or an angle brace beam, attaching a clamp, or an L-shaped mechanism. .

그러나, 이와 같은 종래 방법에서는, 지진, 태풍 등에 의해 강한 진동이 부하되었을 경우의 보강 효과는 충분하지 않으며, 접합부에서 구조재가 간단하게 이반되거나 파손되어, 목조 건축물이 접합부에서 파괴되거나, 심한 경우에는 무너져 버리는 일도 있었다.However, in such a conventional method, the reinforcing effect when a strong vibration is loaded by an earthquake, typhoon or the like is not sufficient, and the structural material is easily transferred or broken at the joint, and the wooden building is destroyed at the joint or severely collapsed. It was thrown away.

그래서, 지진, 태풍 등에 의한 강한 진동에도 충분히 견딜 수 있는 것으로, 도 4에 도시하는 바와 같은 내진 보강 기구(51)가 고안되어, 사용되고 있다.Therefore, the earthquake-resistant reinforcement mechanism 51 shown in FIG. 4 is devised and used to be able to withstand the strong vibration by an earthquake, a typhoon, etc. sufficiently.

이 내진 보강 기구(51)는, 고장력강으로 이루어진 판재를 L형으로 절곡(折曲)시킴과 동시에, 양단부(52a, 52b)의 중간부에 내측으로 절곡시킨 절곡 돌출부(53a, 53b)를 형성한 L형 모재(52)를 설치하여, 이 L형 모재(52)의 절곡 모서리부(52c)에 고장력강으로 이루어진 판재를 절곡시킨 보강 부재(54)를 용접에 의해 고착시키고, 상기 L형 모재(52)의 몇 군데에 고무 등으로 이루어진 완충 부재(55)를 결합시킨 것이다.The seismic reinforcement mechanism 51 bends a plate made of high-strength steel into an L shape, and forms bending protrusions 53a and 53b that are bent inward in the middle of both ends 52a and 52b. The L-shaped base material 52 is provided, and the reinforcing member 54 which bends the board | plate material which consists of high tensile strength steel to the bending edge part 52c of this L-shaped base material 52 is fixed by welding, and the said L-shaped base material 52 ), A shock absorbing member 55 made of rubber or the like is bonded to several places.

이에 따르면, L형 모재(52) 전체 및 그 절곡 돌출부(53a, 53b)에 의해, 수직, 수평 양방향의 강한 진동을 흡수할 수 있고, 보강 부재(54)에 의해 L형 모재(52)의 변형을 복원시킬 수 있으므로, 강한 진동이 부하되어도 목조 건축물이쉽게 파괴되거나, 붕괴되지 않는다.According to this, strong vibrations in both the vertical and horizontal directions can be absorbed by the entire L-shaped base material 52 and its bent protrusions 53a and 53b, and the deformation of the L-shaped base material 52 is made by the reinforcing member 54. Since it can be restored, even if strong vibration is loaded, the wooden building is not easily destroyed or collapsed.

그러나, 상기 내진 보강 기구(51)는 양단부(52a, 52b)의 중간부를 내측으로 절곡시켜 평탄한 절곡 돌출부(53a, 53b)로 했기 때문에, 수직 방향의 진동, 연직 방향의 요동을 흡수하는 효과는 불충분했었다.However, since the seismic reinforcement mechanism 51 was bent inward to the middle portions of both ends 52a and 52b to form flat bending protrusions 53a and 53b, the effect of absorbing the vibration in the vertical direction and the fluctuation in the vertical direction is insufficient. did.

또한, L형 모재(52)에 보강 부재(54)를 용접에 의해 고착시키고, L형 모재(52)의 절곡 모서리부(52c)와 보강 부재(54)의 절곡 모서리부(54c)를 밀착시키고 있기 때문에, 탄성 변형량은 작고, L형 모재(52)의 변형을 복원시키는 효과도 불충분했었다.Further, the reinforcing member 54 is fixed to the L-shaped base material 52 by welding, and the bent edge part 52c of the L-shaped base material 52 and the bent edge part 54c of the reinforcing member 54 are brought into close contact with each other. Since the elastic deformation amount was small, the effect of restoring the deformation of the L-shaped base material 52 was also insufficient.

더욱이, 보강 부재(54)를 고착시키고 있기 때문에, 보강 부재(54)의 각 부에 과대한 부하가 걸리거나, 응력 집중이 발생하거나 해서, 체결용 볼트가 빠지거나, 보강 부재(54) 자신이 빠지거나, 보강 부재(54)에 균열이 생기곤 했었다.Furthermore, since the reinforcing member 54 is fixed, excessive load is applied to each part of the reinforcing member 54, stress concentration occurs, the fastening bolt is pulled out, or the reinforcing member 54 itself is removed. It used to fall out, or the reinforcing member 54 used to crack.

본 발명은, 이러한 문제점을 해결하기 위해 이루어진 것으로, 수직 방향의 진동, 연직 방향의 요동을 흡수하는 효과를 더욱 향상시키고, L형 모재(base metal)의 변형을 복원시키는 효과를 더욱 향상시키며, 게다가 체결용 볼트, 보강 부재 자신이 빠지거나, 보강 부재에 균열이 생기는 것을 최대한 방지하여, 지진, 태풍 등에 의해 강한 진동이 부하되어도 목조 건축물이 붕괴되지 않도록, 내진 성능을 더욱 향상시킨 내진 보강 기구를 제공하는 것을 목적으로 한다.The present invention has been made to solve such a problem, and further improves the effect of absorbing vertical vibration and vertical fluctuations, and further improves the effect of restoring deformation of the L-type base metal. Provides a seismic reinforcement mechanism that further improves seismic performance to prevent the fastening of bolts, reinforcement member itself or cracks in the reinforcement member to prevent collapse of wooden buildings even when strong vibrations are applied by earthquakes and typhoons. It aims to do it.

상기 목적을 달성하기 위해, 본 발명은, 판재를 절곡 형성한 것으로, 양단부의 중간부에 내측으로 만곡시킨 만곡 돌출부를 형성한 L형 모재와, 판재를 절곡 형성한 것으로, 상기 L형 모재의 절곡부에 당접되는 보강 부재와, 탄성 특성, 내수성이 양호한 고무 재료로 이루어지며, 상기 L형 모재의 여러 곳에 결합되는 완충 부재로 내진 보강 기구를 구성한 것이다.In order to achieve the above object, the present invention is formed by bending a plate, an L-shaped base material having a curved protrusion formed by bending inward at an intermediate portion of both ends, and a plate-shaped bending material, and bending of the L-shaped base material. An earthquake-proof reinforcement mechanism is constituted by a reinforcing member abutting on the part, and a rubber material having good elastic properties and water resistance, and a shock absorbing member coupled to various parts of the L-shaped base material.

또한, 보강 부재를 L형 모재에 당접시켰을 때, 보강 부재의 절곡 모서리부와 L형 모재의 절곡 모서리부 사이에 간극이 존재하는 것이 바람직하다.In addition, when the reinforcing member is brought into contact with the L-shaped base material, it is preferable that a gap exists between the bent edge of the reinforcing member and the bent edge of the L-shaped base material.

보강 부재의 양단부를, 보강 부재를 L형 모재에 당접시켰을 때, 그 양 엣지 라인이 상기 만곡 돌출부의 절곡선과 거의 같은 위치에 오는 길이로 하면, 이 절곡부에 의해 보강 부재의 이동이 규제되어, 크게 덜거덕거리지 않는다.When both ends of the reinforcing member abut the reinforcing member on the L-shaped base material, if the two edge lines have a length that is approximately at the same position as the bend line of the curved protrusion, movement of the reinforcing member is regulated by the bent portion. Do not rattle loudly.

상기 판재를 고장력강으로 하면, 인장 강도, 용접성, 노치 인성(notch toughness), 가공성, 내식성이 뛰어나서, 더욱 바람직하다.When the plate is made of high tensile strength steel, the tensile strength, weldability, notch toughness, workability and corrosion resistance are excellent, which is more preferable.

이하, 본 발명의 내진 보강 기구의 적당한 실시 형태에 대해, 도면을 참조하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of the earthquake-resistant reinforcement mechanism of this invention is described with reference to drawings.

내진 보강 기구(1)는, 도 1 및 도 2에 도시하는 바와 같이, L형 모재(2), 보강 부재(3), 완충 부재(4)로 이루어진다.The earthquake-resistant reinforcement mechanism 1 consists of the L-shaped base material 2, the reinforcement member 3, and the shock absorbing member 4, as shown to FIG. 1 and FIG.

L형 모재(2)는, 철강 재료로 이루어진 판재를 절곡시켜 L형으로 만든 것으로, 양단부(2a, 2b)의 중간부에는 내측으로 만곡시킨 만곡 돌출부(5a, 5b)가 형성되어 있다.The L-shaped base material 2 is formed by bending a plate made of a steel material into an L-shape, and curved protrusions 5a and 5b curved inwardly are formed in the middle portions of both ends 2a and 2b.

철강 재료로서는, 구조용 강을 채용하는 것이 바람직하고, 특히 고장력강을 채용하는 것이 바람직하다. 고장력강은, 저탄소강에 망간, 규소, 니켈, 크롬, 몰리브덴 등의 합금 원소를 적당히 조합하여 소량 첨가한 것으로, 일반적으로 인장 강도 50kg/㎟, 항복점 30㎏/㎟ 이상이며, 용접성, 노치 인성, 가공성, 내식성이 뛰어난 것이다.As the steel material, it is preferable to employ structural steel, and in particular, it is preferable to employ high tensile steel. High tensile strength steel is a low carbon steel, which is a small amount of alloying elements such as manganese, silicon, nickel, chromium, molybdenum, and the like added in small amounts. It is excellent in corrosion resistance.

또한, 양단부(2a, 2b)의 양 엣지부 및 절곡 모서리부(2c)의 근방에는 삽입홀(6, 6)이 형성되어 있다.In addition, insertion holes 6 and 6 are formed in the vicinity of both edge portions and the bent edge portions 2c of the both ends 2a and 2b.

보강 부재(3)는, 철강 재료로 이루어진 판재를 절곡시켜 L형으로 만든 것으로, 양단부(3a, 3b)에는 긴 홀(7, 7)이 형성되어 있다.The reinforcing member 3 is formed by bending a plate made of a steel material into an L shape, and long holes 7 and 7 are formed in both ends 3a and 3b.

철강 재료로서는, 마찬가지로 구조용 강을 채용하는 것이 바람직하며, 특히 고장력강을 채용하는 것이 바람직하다.As a steel material, it is preferable to employ structural steel similarly, and it is especially preferable to employ high tensile strength steel.

양단부(3a, 3b)는, 보강 부재(3)를 L형 모재(2)에 당접시켰을 때, 그 양 엣지 라인(8a, 8b)이 만곡 돌출부(5a, 5b)의 절곡선(9a, 9b)과 거의 같은 위치에 오는 길이로 되어 있다.When the both ends 3a and 3b abut the reinforcing member 3 on the L-shaped base material 2, the edge lines 8a and 8b are bent lines 9a and 9b of the curved protrusions 5a and 5b. It is about the same length as.

또한, 보강 부재(3)의 절곡 모서리부(3c)의 바깥면의 곡률 반경(r2)은 L형 모재(2)의 절곡 모서리부(2c)의 내면 곡률 반경(r1)보다 크게 되어 있으며, 따라서 보강 부재(3)를 L형 모재(2)에 당접시켰을 때, 보강 부재(3)의 절곡 모서리부(3c)와 L형 모재(2)의 절곡 모서리부(2c) 사이에 간극(10)이 생기도록 되어 있다.In addition, the radius of curvature r2 of the outer surface of the bent edge portion 3c of the reinforcing member 3 is larger than the inner surface radius of curvature r1 of the bent edge portion 2c of the L-shaped base material 2. When the reinforcing member 3 is brought into contact with the L-shaped base material 2, a gap 10 is formed between the bent edge portion 3c of the reinforcing member 3 and the bent edge portion 2c of the L-shaped base material 2. It is supposed to occur.

완충 부재(4)는, 탄성 특성, 내수성이 양호한 이소푸렌 고무(NR), 부타디엔 고무(BR) 등의 고무 재료로 이루어지며, L형 모재(2)에 결합시킬 수 있도록, 양측부가 자물쇠 모양의 걸림부(4a)로 되어 있다.The shock absorbing member 4 is made of rubber materials such as isoprene rubber (NR) and butadiene rubber (BR) having good elastic properties and water resistance, and both sides of the shock absorbing member are lock-shaped so as to be bonded to the L-shaped base material 2. It is a locking part 4a.

또한, 중앙부에 긴 홀(11)이 형성되고, 바깥면에는 미끄럼 방지를 위한 여러개의 홈부(12, 2, …)가 형성되어 있다.In addition, an elongated hole 11 is formed in the center portion, and a plurality of groove portions 12, 2, ... are formed on the outer surface to prevent slipping.

본 발명의 내진 보강 기구(1)는 이상과 같은 구성이며, 이하와 같이 사용함으로써, 소기의 작용 효과를 발휘한다.The earthquake-resistant reinforcement mechanism 1 of this invention has the structure as mentioned above, and exhibits the desired effect by using as follows.

도 3에 도시하는 바와 같이, L형 모재(2)의 양단부(2a, 2b)에 결합시킨 완충 부재(4)를 토대(13) 및 기둥(14)의 측면에 당접시키고, 삽입홀(6, 6, …), 긴 홀(7, 7), 긴 홀(11, 11, …)에 볼트를 삽입하고, 너트에 의해 체결하여, 내진 보강 기구(1)를 토대(13)와 기둥(14)의 접합부에 부착시킨다.As shown in FIG. 3, the buffer member 4 coupled to both ends 2a and 2b of the L-shaped base material 2 is abutted on the side surface of the base 13 and the pillar 14, and the insertion hole 6, 6, ..., the long holes 7 and 7, the long holes 11, 11, ... and the bolt is inserted, and tightened with a nut, the earthquake-resistant reinforcing mechanism 1 is the base 13 and the pillar 14 It is attached to the junction of.

여기에서, L형 모재(2)에는 만곡 돌출부(5a, 5b)가 형성되어 있고, 이 만곡 돌출부(5a, 5b)는 신축 변형되기 쉬움과 동시에, 비틀림 변형되기도 쉽기 때문에, 수직 방향의 진동, 연직 방향의 요동이 부하되어도, 이 만곡 돌출부(5a, 5b)가 탄성 변형됨으로써, 이러한 진동, 요동들을 충분히 흡수할 수 있다.Here, the curved protrusions 5a and 5b are formed in the L-shaped base material 2, and the curved protrusions 5a and 5b are easily stretched and deformed, and are also easily twisted and deformed. Even if the fluctuations in the direction are loaded, the curved protrusions 5a and 5b are elastically deformed to sufficiently absorb such vibrations and fluctuations.

또, 보강 부재(3)는 L형 모재(2)에 고착되어 있지 않고, 게다가 보강 부재(3)의 절곡 모서리부(3c)와 L형 모재(2)의 절곡 모서리부(2c) 사이에 간극(10)을 형성했기 때문에, L형 모재(2)가 변형될 때에 보강 부재(3)는 별도로 크게 탄성 변형되어, L형 모재(2)의 변형을 복원시키는 효과가 두드러지게 향상된다.In addition, the reinforcing member 3 is not fixed to the L-shaped base material 2, and furthermore, a gap between the bent corner part 3c of the reinforcing member 3 and the bent edge part 2c of the L-shaped base material 2. Since the (10) is formed, when the L-shaped base material 2 is deformed, the reinforcing member 3 is greatly elastically deformed separately, and the effect of restoring the deformation of the L-shaped base material 2 is remarkably improved.

더욱이, 보강 부재(3)는 L형 모재(2)에 고착되어 있지 않고, 게다가 보강 부재(3)의 절곡 모서리부(3c)와 L형 모재(2)의 절곡 모서리부(2c) 사이에 간극(10)을 형성했기 때문에, 종래만큼 보강 부재(3)의 각 부에 과대한 부하는 걸리지 않으며, 응력 집중도 일어나기 힘들어, 볼트가 빠지거나, 보강 부재(3) 자신이 빠지거나,보강 부재(3)에 균열이 생기는 일도 거의 없다.Furthermore, the reinforcing member 3 is not fixed to the L-shaped base material 2, and furthermore, a gap between the bent edge portion 3c of the reinforcing member 3 and the bent edge portion 2c of the L-shaped base material 2. Since 10 is formed, an excessive load is not applied to each part of the reinforcing member 3 as in the prior art, and stress concentration is hardly caused, so that the bolt is pulled out, the reinforcing member 3 is pulled out, or the reinforcing member 3 is removed. ) Cracks hardly occur.

또한, 보강 부재(3)의 양단부(3a, 3b)를 그 양 엣지 라인(8a, 8b)이 만곡 돌출부(5a, 5b)의 절곡선(9a, 9b)과 거의 같은 위치에 오는 길이로 했기 때문에, 보강 부재(3)가 별도로 탄성 변형되었다고 해도, 그 절곡선(9a, 9b)에 의해 이동이 규제되어, 크게 덜거덕거리지 않는다.In addition, since both ends 3a and 3b of the reinforcing member 3 were made into the length which the edge lines 8a and 8b come in substantially the same position as the bend lines 9a and 9b of the curved protrusions 5a and 5b. Even if the reinforcing member 3 is elastically deformed separately, movement is regulated by the bent lines 9a and 9b, so that the reinforcing member 3 is not largely rattled.

또한, L형 모재(2)에 보강 부재(3)를 용접하는 작업은 불필요하기 때문에, 내진 보강 기구(1)의 제조 공정은 간략해지고, 제조 비용도 저렴해진다.In addition, since the work of welding the reinforcing member 3 to the L-shaped base material 2 is unnecessary, the manufacturing process of the earthquake-resistant reinforcing mechanism 1 is simplified, and the manufacturing cost is also low.

상기 실시예에 있어서는, L형 모재(2)는, 1장의 판재를 절곡시켜 형성하였으나, 절곡시킨 2장의 판재를 중합, 고착시켜서 형성해도 된다.In the said Example, although the L-type base material 2 was formed by bending one board | plate material, you may form it by superposing | polymerizing and fixing the two board materials which were bent.
