Description

핀접합파단 철골프레임에 의한 구조물 개구부의 내진보강구조{Seismic Retrofit of Building Structures by Fracture of Pin-Joint}Seismic Retrofit of Building Structures by Fracture of Pin-Joint}

본 발명은 양측의 수직구조체와 상·하부수평구조체로 둘러싸인 구조물의 개구부를 더욱 효과적으로 내진 보강하기 위한 내진보강구조에 관한 것으로, 더욱 상세하게는 구조물의 개구부에 일체로 설치되는 수평·수직의 철골프레임이 서로 분리 거동할 수 있도록 구성한 내진보강구조에 관한 것이다.
The present invention relates to a seismic reinforcement structure for more effectively seismic reinforcing the opening of the structure surrounded by the vertical structure and the upper and lower horizontal structure on both sides, and more specifically, the horizontal and vertical steel frame is integrally installed in the opening of the structure The present invention relates to a seismic reinforcing structure configured to be separated from each other.

일반적으로 건물에는 채광, 통풍, 유출입 등을 위한 창호를 위해 개구부가 마련된다. 개구부는 다른 부분에 비해 응력 집중이 심한데, 특히 지진 등 수평하중이 가해질 경우 개구부에서 인장균열이 시작하여 건물 붕괴로 이어질 수 있다. 이에 따라 내진설계기준이 제정된 1989년 이전에 준공된 철근콘크리트 건물의 경우, 내진성능이 충분치 못하여 지진 발생 시 개구부에서 기인하는 구조손상으로 인해 큰 피해가 발생할 수 있다.In general, the building is provided with openings for windows for mining, ventilation, inflow and outflow. Openings are more concentrated in stress than other parts, especially when horizontal loads such as earthquakes can cause tensile cracking at the openings, leading to building collapse. As a result, reinforced concrete buildings completed before 1989, when the seismic design standards were enacted, may not have sufficient seismic performance and may cause great damage due to structural damage caused by openings during earthquakes.

지진으로부터 인적 피해 및 물적 피해를 최소화하기 위해 다양한 내진보강방법이 적용되고 있다. 대표적인 내진보강방법으로 면진장치를 설치하는 방법이 있는데, 면진장치로서 가새형 댐퍼를 대각 방향으로 설치함으로써 지진에 의한 반복하중이 가해질 때 소성이력거동에 의해 에너지를 소산시키는 방법이다. 그러나 종래의 면진장치 설치방법은 가새형 댐퍼를 지지하기 위한 기둥이나 보와 같은 큰 강성을 갖는 구조부재가 필요하여 시공이 까다롭고, 또한 별도의 설치공간이 필요하여 적용성이 제한적이며, 개구부의 시야를 가린다는 단점이 있다.Various seismic reinforcement methods have been applied to minimize human and physical damage from earthquakes. As a representative seismic reinforcement method, there is a method of installing a seismic isolator. As a seismic isolator, a brace type damper is installed in a diagonal direction to dissipate energy by plastic hysteresis behavior when a cyclic load is applied by an earthquake. However, the conventional seismic isolator installation method requires a structural member having a large rigidity such as a column or beam for supporting the brace damper, which is difficult to construct, and also requires a separate installation space, thereby limiting its applicability. The disadvantage is that it obscures the field of view.

가새형 댐퍼의 단점을 개선하기 위해 도 1과 같은 내진보강방법이 제안되었다. 보는 바와 같이 모서리에서 회동 가능하게 힌지결합된 사각프레임을 건물 개구부에 고정 설치하는 방식으로, 사각프레임의 내부 모서리에 진동에너지를 흡수하여 소성거동하는 댐퍼를 설치하는 방식이다. 이 방식은 모듈화가 가능하고, 거주자의 시야 방해를 최소화하여 창호 설치공간을 충분히 확보할 있다는 점에서 장점이 있다. 하지만 프레임과 댐퍼가 모든 하중을 지지하는 방식이므로 지진력에 대한 하중 분산의 효율성이 떨어지고 또한 효과적인 보강을 위해서는 단면성능이 큰 부재가 요구되며, 모서리 댐퍼에 의해 여전히 시야가 가려지는 단점이 있다.In order to improve the shortcomings of the damper-type damper, a seismic reinforcing method as shown in FIG. 1 has been proposed. As can be seen by fixing the hinged square frame rotatably at the corner of the building opening in the corner, the damper for absorbing the vibration energy in the inner corner of the square frame to install plastic behavior. This method is advantageous in that it can be modularized and secure enough space for installing windows by minimizing the disturbance of the occupants' view. However, since the frame and the damper support all the loads, the efficiency of load distribution against seismic force decreases, and for the effective reinforcement, a member having a large cross-sectional performance is required, and the view is still obscured by the edge damper.

도 1의 내진보강방법을 개선하기 위해 본 발명자는 도 2와 같은 내진보강방법을 제안하였다. 도 2의 내진보강방법은 특허 제10-1165320호에 따른 것으로, 건물 개구부에 철골프레임을 설치하고 철골프레임의 내측 하부에 철근콘크리트벽체를 시공하는 방식이다. 건물 개구부의 하부를 철근콘크리트벽체로 내력을 보강하는 한편 철골프레임이 지지해야 하는 모멘트 팔길이를 줄인 방식이 된다.
In order to improve the seismic reinforcing method of Figure 1, the present inventors proposed a seismic reinforcing method as shown in FIG. The seismic reinforcement method of FIG. 2 is in accordance with Patent No. 10-1165320, in which a steel frame is installed in a building opening, and a reinforced concrete wall is installed in an inner lower portion of the steel frame. The lower part of the building opening is reinforced with reinforced concrete walls while reducing the moment arm length that the steel frame must support.

본 발명은 구조물 개구부에 철골프레임을 설치하여 내진보강하는 내진보강구조를 개선하고자 개발된 것으로서, 수평·수직의 철골프레임이 서로 분리 거동할 수 있도록 구성하여 내진보강효과를 극대화할 수 있는 방안을 제공하는데 기술적 과제가 있다.

In order to solve the above technical problem, the present invention is a seismic reinforcement structure for seismic reinforcement structure for seismic reinforcement of the structure surrounded by the vertical structure on both sides and the upper and lower horizontal structure, facing each of the upper and lower horizontal structure at the opening of the structure. Upper and lower horizontal frames, which are fixedly installed but shorter than the distance between the vertical structures on both sides, and are installed at both ends of the vertical structures spaced apart from the vertical structures on both sides, and are fixedly installed to face each of the vertical structures on both sides at the opening of the structure.

본 발명은 양측의 수직구조체(S1)와 상·하부수평구조체(S2)로 둘러싸인 구조물의 개구부에 내진보강과 함께 창호가 설치되는 내진보강 창호구조에 관한 것으로, 내진보강을 위해 구조물 개구부에 수평·수직으로 설치한 철골프레임이 지진하중에 대해 분리 거동할 수 있도록 구성된다는데 특징이 있다. 구조물의 개구부에서 양측의 수직구조체(S1)는 기둥 또는 내력벽체가 될 수 있고, 상·하부수평구조체(S2)는 보(S21) 또는 슬래브(S2)가 될 수 있다.The present invention relates to an earthquake-proof reinforcement window structure in which windows are installed together with seismic reinforcement in the openings of a structure surrounded by vertical structures (S1) and upper and lower horizontal structures (S2) on both sides. The steel frame frame installed vertically is characterized by being configured to separate the seismic load. In the opening of the structure, the vertical structures S1 on both sides may be columns or bearing walls, and the upper and lower horizontal structures S2 may be beams S21 or slabs S2.

구체적으로 본 발명에 따른 내진보강 창호구조는, 구조물의 개구부에서 상·하부수평구조체(S2) 각각에 대면하게 고정 설치되되 양측의 수직구조체(S1) 사이 거리보다 짧은 길이로 마련되어 양단부가 양측의 수직구조체(S1)와 이격하게 설치되는 상·하부수평프레임(112);과, 구조물의 개구부에서 양측의 수직구조체(S1) 각각에 대면하게 고정 설치되되 상·하부수평프레임(112) 사이에 배치되어 양단부가 파단핀(120)에 의해 상·하부수평프레임(112)에 핀접합 설치되는 양측의 수직프레임(111);을 포함하여 구성된다. 여기서 파단핀(120)은 쉽게 파단될 수 있도록 중간에 파단유도홈(121)이 형성된 것이 바람직하다.Specifically, the seismic reinforcement window structure according to the present invention is fixedly installed facing each of the upper and lower horizontal structure (S2) at the opening of the structure, but is provided with a length shorter than the distance between the vertical structure (S1) on both sides of the both ends vertically Upper and lower horizontal frame 112 is spaced apart from the structure (S1); And is fixedly installed facing each of the vertical structure (S1) on both sides in the opening of the structure is disposed between the upper and lower horizontal frame (112) It is configured to include; both ends are vertical frames 111 on both sides that are pin-joined to the upper and lower horizontal frame 112 by the breaking pin 120. Here, the breaking pin 120 is preferably a break induction groove 121 is formed in the middle so that it can be easily broken.

위와 같은 구성에 따라 수평하중이 작용하면 파단핀(120)이 파단하여 상·하부수평프레임(112)과 양측의 수직프레임(111)이 분리 거동하게 되며, 이로써 분리 거동으로 에너지가 소산되면서 수평하중에 저항하게 된다. 이때 분리 거동에 따른 변위는 도 5에서와 같이 상·하부수평프레임(112)과 수직구조체(S1) 사이의 이격 공간을 통해 흡수된다. 다만 수직프레임(111)과 상·하부수평프레임(112)은 파단핀(120)의 파단강도보다 큰 하중에도 견딜 수 있게 구조체에 고정되어야 하는데, 그래야 파단핀(120)이 파단되어도 수직프레임(111)과 상·하부수평프레임(112)은 각각 구조체에 고정된 채 구조체와 일체 거동하면서 서로 분리 거동하게 된다.When the horizontal load acts according to the configuration as described above, the breaking pin 120 breaks and the upper and lower horizontal frames 112 and the vertical frames 111 on both sides are separated, thereby dissipating energy by the separating behavior and thus horizontal load. Will resist. At this time, the displacement according to the separation behavior is absorbed through the spaced space between the upper and lower horizontal frame 112 and the vertical structure (S1). However, the vertical frame 111 and the upper and lower horizontal frames 112 should be fixed to the structure to withstand the load greater than the breaking strength of the breaking pin 120, so that even if the breaking pin 120 is broken, the vertical frame 111 ) And the upper and lower horizontal frames 112 are separated from each other while being integral with the structure while being fixed to the structure.

수직프레임(111)과 상·하부수평프레임(112)은 여러 방식으로 구조체에 고정 설치할 수 있으나, 바람직하게 케미컬 앵커(F1)로 구조체(S1, S2)에 고정하고 사이 틈에 필러(F2, 무수축몰탈, 고기능 주입제 등)를 채우는 방식으로 처리하면 구조체(S1, S2)의 일체화를 도모할 수 있다. 또는 수직프레임(111)과 상·하부수평프레임(112)과 구조체(S1, S2) 사이에 탄성단열재를 설치하면서 케미컬 앵커(F1)로 고정할 수도 있는데, 탄성단열재는 철골프레임(110)과 구조체(S1, S2) 사이에서 유연하게 대응하면서 틈새없이 설치되기 때문에 단열성능 확보에 기여하고 더불어 지지하중 흡수에도 기여한다. 케미컬 앵커(F1)로 고정한 후에는 앵커머리에 밀봉캡을 씌워 케미컬 앵커(F1)를 보호하도록 한다. 철골프레임(110)은 H형강을 이용하는 것이 단면성능 확보와 케미컬 앵커(F1)의 설치에도 유리하며, 물론 다른 단면의 철골부재도 가능하다. 다만 H형강을 이용한다면 H형강 수직프레임(111)의 양단부에 엔드플레이트(114)를 접합하여 엔드플레이트(114)를 H형강 수평프레임(112)의 플랜지에 파단핀(120)으로 핀접합한다. 또한 H형강에 의한 상·하부수평프레임(112)과 양측의 수직프레임(111)은 보강스티프너(113)로 보강할 수 있다.Vertical frame 111 and the upper and lower horizontal frame 112 can be fixed to the structure in a number of ways, but preferably fixed to the structure (S1, S2) with a chemical anchor (F1) in the gap between the filler (F2, no By shrinking mortar, a highly functional injecting agent, etc.), the structures S1 and S2 can be integrated. Alternatively, while the elastic insulation is installed between the vertical frame 111, the upper and lower horizontal frames 112, and the structures S1 and S2, it may be fixed by the chemical anchor F1. The elastic insulation is the steel frame 110 and the structure. Flexible installation between (S1, S2), without gaps, contributes to securing insulation performance and also to absorbing support loads. After fixing with the chemical anchor (F1) to cover the anchor cap to protect the chemical anchor (F1). The steel frame 110 is advantageous to use the H-shaped steel to secure the cross-sectional performance and the installation of the chemical anchor (F1), as well as the steel frame member of other cross-section is possible. However, if the H-shaped steel is used, the end plates 114 are joined to both ends of the H-beam vertical frame 111 to pin-bond the end plates 114 to the flanges of the H-frame horizontal frame 112 with the breaking pins 120. In addition, the upper and lower horizontal frame 112 and the vertical frame 111 on both sides by the H-shaped steel can be reinforced by the reinforcement stiffener 113.

한편 상·하부수평프레임(112)에 양측의 수직프레임(111)을 핀접합 설치할 때, 그 사이에는 미끄럼유도판(130)을 더 설치할 수 있다. 미끄럼유도판(130)은 파단핀(120)이 파단하여 수직프레임(111)과 상·하부수평프레임(112)이 분리 거동할 때 마찰 저항을 줄여 분리 거동을 유연하게 유도하는 역할을 하며, 테프론(PTFE) 소재의 판이면 적당하다. 또한 상·하부수평프레임(112)과 양측의 수직구조체(S1) 사이의 이격 공간에는 탄성단열재(140)를 더 설치할 수 있다. 탄성단열재(140)는 지진하중의 작용으로 수직프레임(111)과 상·하부수평프레임(112)이 분리 거동할 때 탄성에 의한 신축으로 변위를 흡수하면서 수평하중을 완충하는 역할을 한다.
On the other hand, when pin-mounting the vertical frame 111 on both sides to the upper and lower horizontal frame 112, the sliding guide plate 130 may be further installed therebetween. The sliding guide plate 130 serves to flexibly induce separation behavior by reducing frictional resistance when the breaking pin 120 breaks and the vertical frame 111 and the upper and lower horizontal frames 112 separate. A plate of (PTFE) material is suitable. In addition, the elastic insulating material 140 may be further installed in the space between the upper and lower horizontal frames 112 and the vertical structure S1 on both sides. The elastic insulating material 140 serves to cushion the horizontal load while absorbing the displacement due to elasticity when the vertical frame 111 and the upper and lower horizontal frames 112 are separated by the action of the seismic load.
