Description

폴리머 콘크리트 유닛 및 폴리머 콘크리트 유닛의 분할 형성 구조체Split concrete structure of polymer concrete unit and polymer concrete unit
본 발명은 폴리머 콘크리트 유닛 및 폴리머 콘크리트 유닛의 분할 형성 구조체에 관한 것으로, 더욱 상세하게는 도로 또는 활주로와 같은 노면의 보수부를 폴리머 콘크리트로 보수하는 경우에, 보수부에 가해지는 응력에 의해 쉽게 파손되지 않도록, 구조가 개선된 폴리머 콘크리트 유닛 및 이를 수용하기 위한 구조체에 관한 것이다.The present invention relates to a polymer concrete unit and a split-forming structure of a polymer concrete unit, and more particularly, when repairing a repair portion of a road surface such as a road or a runway with polymer concrete, it is not easily broken by stress applied to the repair portion. To a polymer concrete unit having an improved structure and a structure for accommodating the same.
일반적으로, 토목 및 건설 재료로서 시멘트 콘크리트가 구조적, 경제적 장점으로 인해 널리 사용되고 있다. 하지만, 해당 재료의 경우 충분한 강도를 발현시키기 위해서는 상당한 양생시간이 소요되기 때문에 도로 및 활주로의 유지보수와 같은 빠른 개방 시간을 요구하는 분야에서는 적합하지 않다.In general, cement concrete is widely used as a civil and construction material due to its structural and economic advantages. However, the material is not suitable for applications requiring fast opening times, such as road and runway maintenance, as it takes considerable curing time to develop sufficient strength.
위 문제점을 개선시키기 위한 많은 연구들이 활발히 진행되고 있으며, 대안 중 하나로 폴리머 콘크리트가 있다.A lot of research is being actively conducted to improve the above problems, and one alternative is polymer concrete.
폴리머 콘크리트는 경화시간 조절이 가능하며, 우수한 강도, 내마모성,그리고 내약품성을 지닌다. 또한, 다른 재료와의 부착성이 우수하기 때문에 도로 및 활주로 포장의 유지보수재료로 적합하다. Polymer concrete has a hardening time control, excellent strength, abrasion resistance and chemical resistance. In addition, it is suitable as a maintenance material for road and runway pavement because of its excellent adhesion with other materials.
하지만, 폴리머 콘크리트는 시멘트 콘크리트와 상이한 열팽창계수를 가지고 (일반적으로 시멘트 콘크리트의 열팽창계수의 3~4배)있기 때문에, 도로 및 활주로 포장면이 반복적인 온도변화에 노출되는 경우, 보수계면 부근의 수축, 팽창이 불연속적으로 발생하게 되며, 결과적으로 이는 보수계면에서 상당한 응력을 유발하게 된다.However, polymer concrete has a different coefficient of thermal expansion than cement concrete (generally three to four times the coefficient of thermal expansion of cement concrete), so that the road and runway pavement shrinks near the water surface when exposed to repeated temperature changes. This results in discontinuous expansion, resulting in significant stress in the water interface.
이와 같은 현상은 보수재료로 사용된 폴리머 콘크리트에 비해 낮은 수치의 압축 및 인장강도를 가지고 있는 시멘트 콘크리트의 조기 파손을 유발할 수 있다.This phenomenon can lead to premature failure of cement concrete, which has a lower compressive and tensile strength than polymer concrete used as a repair material.
이와 같이, 폴리머 콘크리트의 경우 시멘트 콘크리트에 비해 우수한 물리적 특성, 내구성, 그리고 화학적 내성을 지니며, 조속한 경화 특성으로 인해 조기 개방이 가능하므로 많은 토목 및 건설 분야에서 사용되고 있지만, 폴리머 콘크리트와 시멘트 콘크리트 간의 상이한 물리적 특성 차이로 인해 발생하는 문제들을 해결한사례 및 관련 연구는 부족한 실정이다.As such, polymer concrete has excellent physical properties, durability, and chemical resistance compared to cement concrete, and is used in many civil and construction fields because of its early opening due to rapid curing properties, but it is different from polymer concrete and cement concrete. There are not enough cases and related studies that solve problems caused by differences in physical characteristics.

상기 중심부와 계면부 사이에는, 상기 중심부에서 계면부 측으로 갈수록 연성이 커지는 적어도 하나의 강성 그레이딩부가 마련되어 있는 것이 바람직하다. It is preferable that at least one rigid grading portion is provided between the central portion and the interface portion, the ductility of which increases from the central portion toward the interface portion side.
상기 계면부는, 상기 중심부보다 연성을 가진 고무 재질의 함량비가 더 큰 것이 바람직하다.Preferably, the interface portion has a greater content ratio of a ductile rubber material than the central portion.
그리고, 상기 목적을 달성하기 위한 본 발명에 의한 폴리머 콘크리트 유닛의 분할 형성 구조체는, 콘크리트 블럭의 보수부의 계면 측에 위치하는 부분에서 상기 보수부의 중심 측으로 갈수록 상기 보수부에 작용하는 응력에 대한 강도 및 재료강성이 커지는 폴리머 콘크리트 유닛을, 상기 재료강성이 서로 다른 부분을 구획하여 형성하기 위한 것으로, 상기 보수부의 가장자리에 대응되는 테두리 형상을 가지는 베이스패널; 상기 베이스패널의 마주하는 한 쌍의 가장자리들을 가로 질러 배치되고, 상기 베이스패널에 착탈가능하게 결합되는 적어도 하나의 제1구획패널; 및 상기 제1구획패널의 설치방향과 교차되는 방향을 따라 배치되고, 상기 베이스패널 및 제1구획패널에 착탈가능하게 결합되는 적어도 하나의 제2구획패널;을 포함하여 이루어지는 것을 특징으로 한다. In addition, the division-forming structure of the polymer concrete unit according to the present invention for achieving the above object, the strength to the stress acting on the repair portion from the portion located on the interface side of the repair portion of the concrete block toward the center side of the repair portion; A base panel for forming a polymer concrete unit having increased material rigidity by partitioning portions having different material rigidities, the base panel having an edge shape corresponding to an edge of the repair part; At least one first partition panel disposed across a pair of opposing edges of the base panel and detachably coupled to the base panel; And at least one second compartment panel disposed along a direction crossing the installation direction of the first compartment panel and detachably coupled to the base panel and the first compartment panel.
상기 베이스패널에는, 상기 제1구획패널 및 제2구획패널의 가장자리가 끼워 맞춤되는 베이스측 끼움홈이 형성되어 있는 것이 바람직하다. Preferably, the base panel includes a base side fitting groove in which edges of the first compartment panel and the second compartment panel are fitted.

상술한 바와 같은 구성을 가지는 본 발명에 의한 폴리머 콘크리트 유닛은, 중심부의 응력저항성을 크게 확보하고 보수하고자 하는 보수부의 계면에 맞대이는 계면부를 상대적으로 연성인 재질로 형성함으로써 계면부에서 발생하는 응력을 완화시켜, 도로 또는 활주로와 같은 노면의 보수부에 교체 설치되는 경우에도 파손되지 않고 오랫동안 사용할 수 있는 장점을 가진다. In the polymer concrete unit according to the present invention having the above-described configuration, the stress generated at the interface portion is formed by forming a relatively soft material of the interface portion facing the interface of the repair portion to be largely secured and maintaining the stress resistance of the center portion. To alleviate, even when the replacement part is installed in the repair portion of the road, such as a road or runway has the advantage that can be used for a long time without being damaged.
그리고, 상술한 바와 같은 구성을 가지는 본 발명에 의한 폴리머 콘크리트 유닛의 분할 형성 구조체는, 제1구획패널과 제2구획패널을 각각 베이스패널의 복수의 베이스측 끼움홈들 중 어느 하나에 끼워서, 폴리머 콘크리트 유닛의 중심부에 해당하는 규격의 공간을 형성하여 둔 다음, 그 공간에 중심부를 형성할 수 있게 하고, 순차적으로 제1구획패널과 제2구획패널을 베이스패널의 다른 위치에 결합하여서 중심부와는 다른 물성을 가지는 부분을 형성할 수 있게 하는 장점을 도출한다. In the divided-forming structure of the polymer concrete unit according to the present invention having the configuration as described above, the first partition panel and the second partition panel are respectively inserted into one of a plurality of base side fitting grooves of the base panel, After forming a space of the standard corresponding to the center of the concrete unit, it is possible to form a center in the space, and sequentially combine the first compartment panel and the second compartment panel in different positions of the base panel to The advantage of being able to form parts with different physical properties is derived.
결국, 이러한 장점은, 폴리머 콘크리트 유닛의 서로 다른 물성을 가진 중심부와 계면부를 일정 규격을 가진 틀을 이용하여 순차적으로 제작할 수 있게 됨에 따라, 공기의 단축, 공사비의 절감 및 품질 관리를 용이하게 할 수 있는 효과를 기대할 수 있게 한다.After all, this advantage, as it is possible to sequentially produce the center and the interface portion of the polymer concrete unit with different properties using a frame having a certain standard, it can facilitate the shortening of air, reduction of construction cost and quality control.

이하에서는 본 발명의 일실시예에 따른 폴리머 콘크리트 유닛을 첨부된 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, a polymer concrete unit according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 일실시예에 따른 폴리머 콘크리트 유닛의 사시도이고, 도 2는 본 발명 일실시예의 단면도이다. 1 is a perspective view of a polymer concrete unit according to an embodiment of the present invention, Figure 2 is a cross-sectional view of one embodiment of the present invention.
이들 도면에 도시된 바와 같이, 본 발명에 의한 폴리머 콘크리트 유닛(10)은, 보수가 요구되는 보수부(20)를 가지는 콘크리트 블럭(100)에 설치되는 것으로, 상기 보수부(20)에 유발되는 응력에 대한 저항성이 서로 다른 중심부(11)와 계면부(13)를 포함하여 이루어진다.As shown in these drawings, the polymer concrete unit 10 according to the present invention is to be installed in the concrete block 100 having the repair portion 20 is required to repair, caused by the repair portion 20 The resistance to stress includes a central portion 11 and an interface portion 13 different from each other.
즉, 상기 중심부(11)는, 상기 보수부(20)의 중심 측에 위치하는 것으로, 상기 보수부(20)에 작용하는 응력에 대한 강도 및 재료강성이 상기 계면부(13)를 포함한 다른 부분보다 큰 재질로 형성되고, 상기 계면부(13)는 상기 보수부(20)의 계면(21)과 맞대이는 부분으로, 상기 중심부(11)보다 상대적으로 작은 재료강성을 가지는 연성인 재질로 형성되고, 시멘트 재질로 형성되는 콘크리트 블럭(100)과 유사한 수치의 재료강성, 압축강도 및 인장강도를 가지는 것이 바람직하다. That is, the central portion 11 is located at the center side of the water retaining portion 20, and the other portion including the interface portion 13 in strength and material rigidity with respect to the stress acting on the water retaining portion 20. It is formed of a larger material, the interface portion 13 is a portion facing the interface 21 of the repair portion 20, is formed of a soft material having a material stiffness relatively smaller than the central portion (11) , It is preferable to have a material stiffness, compressive strength and tensile strength similar to that of the concrete block 100 formed of cement material.
예컨대, 폐타이어나 실리콘 고무와 같은 고무 재질의 함량비를 상기 계면부(13)는 많게 상기 중심부(11)는 적게 함으로써, 상기 중심부(11)와 계면부(13)가 서로 다른 응력저항성을 갖도록 형성하는 것이 가능하다. For example, the interface portion 13 has a large content ratio of rubber material such as waste tires or silicone rubber so that the central portion 11 is less, so that the central portion 11 and the interface portion 13 have different stress resistance. It is possible to form.
이와 같이, 상기 중심부(11)를, 보수가 요구되는 콘크리트 블럭의 강도보다 크거나, 혹은 동일한 강도를 가지는 재질로 형성하고, 상기 계면부(13)를, 상기 보수부(20)의 수축, 팽창을 수용할 수 있는 연성인 재질로 형성하게 되면, 온도, 압력 또는 하중 등에 의해 상기 보수부(20)에 불연속적으로 응력이 발생하여 상기 계면부(13)의 수축, 팽창이 초래되는 경우에도, 계면부에서 시멘트 콘크리트 블럭(100)을 이루고 있는 재료의 강도보다 낮은 수치의 압축 및 인장 응력이 발생하기 때문에, 폴리머 콘크리트 유닛(10)의 거동 변화에 의해 시멘트 콘크리트 블럭이 쉽게 파손되지 않게 된다. In this manner, the central portion 11 is formed of a material having a strength greater than or equal to that of the concrete block requiring repair, and the interface portion 13 is contracted and expanded of the repair portion 20. When formed of a flexible material that can accommodate the above, even when the stress is discontinuously generated in the repair portion 20 due to temperature, pressure or load, etc., the contraction, expansion of the interface portion 13 is caused, Since the compressive and tensile stress of the value lower than the strength of the material constituting the cement concrete block 100 is generated at the interface portion, the cement concrete block is not easily damaged by the behavior change of the polymer concrete unit 10.
결국, 본 발명에 의한 폴리머 콘크리트 유닛(10)은, 중심부(11)의 응력저항성을 크게 확보하고 보수하고자 하는 보수부(20)의 계면(21)에 맞대이는 계면부(13)를 상대적으로 연성인 재질로 형성함으로써 계면부에서 발생하는 응력을 완화시켜, 보수부(20)에 교체 설치되는 경우에도 파손되지 않고 오랫동안 사용할 수 있는 장점을 가진다. As a result, the polymer concrete unit 10 according to the present invention is relatively ductile to the interface 13 facing the interface 21 of the repair portion 20 to secure and repair the stress resistance of the central portion 11 significantly. By forming the phosphor material to relieve the stress generated in the interface portion, even if the replacement portion is installed in the repair portion 20 has the advantage that can be used for a long time without being damaged.
본 실시예에서 상기 폴리머 콘크리트 유닛(10)은, 상기 중심부(11)와 계면부(13) 사이에 마련되는 적어도 하나의 강성(Stiffeness) 그레이딩부(15)를 더 포함하여 이루어진다.In the present embodiment, the polymer concrete unit 10 further includes at least one stiffness grading portion 15 provided between the central portion 11 and the interface portion 13.
즉, 상기 강성 그레이딩부(15)는, 상기 중심부(11)보다는 연성인 재질로, 상기 계면부(13)보다는 강성인 재질로 형성된다.That is, the rigid grading part 15 is formed of a material that is softer than the central part 11 and is formed of a material that is harder than the interface part 13.
예컨대, 폐타이어나 실리콘 고무와 같은 고무 재질의 함량비를 조절함으로써, 상기 중심부(11)에서 계면부(13) 측으로 갈수록 점진적인 연성을 갖도록 구성할 수 있다. For example, by adjusting the content ratio of the rubber material such as waste tires and silicone rubber, it can be configured to have a gradual ductility toward the interface portion 13 side from the central portion (11).
한편, 상술한 바와 같은 폴리머 콘크리트 유닛(10)은, 상기 중심부(11)와 강성 그레이딩부(15)와 계면부(13)를, 이중사출 등에 의한 방식에 의해 서로 다른 강성을 가지도록 형성하는 것도 가능하나, 아래와 같이 폴리머 콘크리트 유닛의 분할 형성 구조체에 의해 강도와 강성이 서로 다른 부분을 분할하여 형성하는 것도 가능하다. On the other hand, the polymer concrete unit 10 as described above, it is also possible to form the central portion 11, the rigid grading portion 15 and the interface portion 13 to have different rigidity by a method such as double injection. It is possible, but it is also possible to form by dividing the parts with different strength and rigidity by the divided forming structure of the polymer concrete unit as follows.
