콘크리트 균열 억제형 앵커볼트 정착판{Concrete crack resisting type anchor plate}Concrete crack resisting type anchor plate {Concrete crack resisting type anchor plate}

본 발명은 기초 콘크리트에 매설되어 앵커볼트가 결합되는 정착판에 관한 것으로, 금속판을 절곡하여 확장부, 외곽부 및 가동부를 구성하되, 앵커볼트에 외력이 작용함에 따라 외곽부 내부의 가동부가 변형되면서 기초 콘크리트에 가해지는 충격을 흡수할 수 있도록 함으로써 기초 콘크리트의 균열 내지 취성파괴를 방지한 것이다.The present invention relates to a fixing plate buried in the foundation concrete coupled to the anchor bolt, bending the metal plate to configure the expansion portion, the outer portion and the movable portion, while the movable part inside the outer portion is deformed as the external force acts on the anchor bolt By absorbing the impact on the foundation concrete to prevent cracking or brittle fracture of the foundation concrete.

도 1은 옥외 전광판이 앵커볼트(10)를 통하여 기초 콘크리트(20)에 설치된 상태를 예시한 것으로, 이와 같이 상측에 캔틸레버(cantilever)가 구성된 구조물의 경우 하부 지지점에 축방향 하중 뿐 아니라 모멘트 및 매설부분에 대한 인발력이 작용하므로, 도시된 바와 같이 다수의 앵커볼트(10)를 콘크리트(20)에 결합하여 견고하게 고정하게 된다.FIG. 1 illustrates a state in which an outdoor display board is installed on the foundation concrete 20 through an anchor bolt 10. In the case of a structure having a cantilever formed on the upper side, the momentary and buried loads as well as axial loads are provided at the lower support points. As the drawing force acts on the part, as shown, a plurality of anchor bolts 10 are coupled to the concrete 20 to be firmly fixed.

이러한 앵커볼트(10)는 기초 콘크리트(20)의 타설 및 양생이 완료된 후, 결 합공을 천공하고 체결하거나, 기초 콘크리트(20)의 타설시 암나사를 매입하고 양생이 완료된 후 체결하는 방식으로 시공된다.The anchor bolt 10 is constructed in such a way that after the casting and curing of the foundation concrete 20 is completed, perforating and fastening the coupling holes, or buying the female screw when the foundation concrete 20 is poured, and fastening after completion of curing. .

이렇듯, 앵커볼트(10)와 기초 콘크리트(20)는 역학적으로 단일체로서 거동하게 되는 바, 앵커볼트(10)에 작용하는 외력이 기초 콘크리트(20)에 그대로 전달되며, 상대적으로 취성체(脆性體)인 콘크리트(20)는 앵커볼트(10)의 변형을 흡수하지 못하고 균열이 발생되거나 파괴되게 된다.As such, the anchor bolt 10 and the foundation concrete 20 are behaving as a single body mechanically, the external force acting on the anchor bolt 10 is transmitted to the foundation concrete 20 as it is, relatively brittle body (脆性 體The concrete 20 is not absorbed the deformation of the anchor bolt 10 will be cracked or generated.

특히, 앵커볼트(10)에 의하여 지지되는 상부 구조물에 반복적인 하중이 재하되거나 진동하중이 가해지는 경우 콘크리트(20)의 파괴 양상이 더욱 심각해지며, 결국 앵커볼트(10)의 인발저항력이 급격하게 저하되면서 상부 구조물의 안정성에 심각한 문제를 야기하게 된다.In particular, when a repetitive load or vibration load is applied to the upper structure supported by the anchor bolt 10, the fracture pattern of the concrete 20 becomes more serious, and ultimately, the pullout resistance of the anchor bolt 10 rapidly increases. Degradation causes serious problems in the stability of the superstructure.

본 발명의 상세한 구성을 첨부된 도면을 통하여 설명하면 다음과 같다.The detailed configuration of the present invention through the accompanying drawings as follows.

우선 도 2는 본 발명의 매설상태를 도시한 것으로, 동 도면을 통하여 알 수 있는 바와 같이, 본 발명은 앵커볼트(10)가 결합되는 암나사가 내주면에 형성된 결합부(35)와, 이 결합부(35)에 부착되고 결합부(35)를 포위하는 가동부(33)와, 가동부(33)에서 이격되고 가동부(33)를 포위하는 외곽부(32)와, 가동부(33) 및 외곽부(32)의 측단에 각각 연결되는 확장부(31)로 구성되며, 가동부(33)와 확장부(31)의 연결부위에는 절곡된 파형부(34)가 형성된다.First, Figure 2 shows the buried state of the present invention, as can be seen through the figure, the present invention is a coupling portion 35 formed on the inner circumferential surface of the female screw to which the anchor bolt 10 is coupled, this coupling portion A movable portion 33 attached to the 35 and surrounding the engaging portion 35, an outer portion 32 spaced apart from the movable portion 33 and surrounding the movable portion 33, and a movable portion 33 and an outer portion 32. Consists of the extension portion 31 is connected to the side end of each), the curved portion 34 is formed at the connection portion of the movable portion 33 and the expansion portion 31.

가동부(33)에 부착되는 결합부(35)는 도 3에서와 같이, 일종의 암나사로서 용접 등의 가공을 통하여 가동부(33)에 밀착 부착된다.The coupling part 35 attached to the movable part 33 is closely attached to the movable part 33 as a kind of female screw through a process such as welding.

또한, 확장부(31)에는 다수의 키(key)(36)가 형성되어 콘크리트(20)와의 부착력을 확보하고 인발에 저항하게 되는데, 이들 키(36)는 확장부(31)를 구성하는 금속판을 부분 절개한 후 절개된 부위를 절곡함으로써 형성하게 되며, 이러한 절개 및 절곡가공은 프레스 가공을 통하여 동시에 진행할 수도 있다.In addition, the expansion portion 31 is formed with a plurality of keys (36) to secure the adhesion to the concrete 20 and to resist the draw, these keys 36 are the metal plate constituting the expansion portion 31 After the partial incision is formed by bending the incision site, this incision and bending process may be carried out at the same time through the press working.

파형부(34)는 그 문언적 의미와 같이 금속판을 파형(波形)으로 절곡한 부분으로서, 도 4에서와 같이, 해당 부위에서의 변형 및 복원성을 최대한 확보할 수 있도록 구성된 것이며, 이 파형부(34)를 통하여 외곽부(32) 내부의 가동부(33)가 변형되면서 앵커볼트(10)에서 가해지는 충격 또는 진동을 흡수하게 된다.The corrugated portion 34 is a portion in which a metal plate is bent into a wave shape in a literal sense, and as shown in FIG. 4, the corrugated portion 34 is configured to ensure maximum deformation and restorability at the corresponding portion. As the movable part 33 inside the outer portion 32 is deformed through 34, the shock or vibration applied by the anchor bolt 10 is absorbed.
