Description
본 고안은 콘크리트 구조물을 크레인으로 인양할 때 콘크리트구조물에 매입하여 사용하는 삽입앵커에 관한 것으로서, 보다 상세하게는 삽입앵커의 하단부를 절곡시켜 삽입앵커와 콘크리트구조물간의 결합력을 강화시킨 콘크리트구조물 인양용 삽입앵커에 관한 것이다.The present invention relates to an insertion anchor used to purchase a concrete structure by lifting it into a concrete structure. More specifically, the lower end of the insertion anchor is bent to reinforce the bonding force between the insertion anchor and the concrete structure. It is about anchors.
예를들어 조립식주택공사 현장에서는 콘크리트를 직접 양생하지 않고 설계규격에 맞도록 미리 양생된 콘크리트패널이나 블록(이하, 콘크리트구조물)을 현장으로 옮겨와서 조립한다.For example, the prefabricated house construction site does not cure concrete directly, but pre-cured concrete panels or blocks (hereinafter referred to as concrete structures) are assembled to meet the design standards.
상기와 같이 미리 형성되어진 콘크리트구조물은 대부분 수 톤(ton)이나 수 십 톤의 중량을 가지므로 대형크레인을 통해서만 인양 운반 및 조립작업을 할 수 있다. 과거 콘크리트구조물을 운반하기 위해서는 로프나 와이어로 콘크리트구조물을 감아 크레인에 걸어야 하였으나 작업이 힘들고 비효율적이라 인양용앵커가 사용되기 시작하였다.Pre-formed concrete structures as described above are mostly tons (tons) or tens of tons of weight can be lifted transport and assembly work only through large cranes. In the past, to transport concrete structures, it was necessary to wind the concrete structure with a rope or wire and hang it on a crane. However, the lifting anchors began to be used because the work was difficult and inefficient.
인양용앵커는 콘크리트구조물의 양성시 몸체의 일부를 구조물에 매입하여 고정시킨 요소이다. 상기 앵커의 상부는 콘크리트구조물의 외부로 노출되어 통상 아이볼트와 결합한다. 따라서 크레인의 인양고리를 아이볼트에 끼운 상태로 들어올림으로서 콘크리트구조물을 인양하거나 이동시킬 수 있는 것이다.The lifting anchor is an element fixed by embedding a part of the body into the structure during the formation of the concrete structure. The upper part of the anchor is exposed to the outside of the concrete structure is usually combined with the eye bolt. Therefore, by lifting the lifting hook of the crane into the eye bolts can lift or move the concrete structure.
도 1은 종래의 콘크리트구조물 인양용 삽입앵커를 설명하기 위한 도면으로서 콘크리트구조물에 앵커가 고정된 상태의 도면이다.1 is a view for explaining the conventional anchor lifting insert for concrete structures is a view of the anchor fixed to the concrete structure.
도면을 참조하면, 종래의 삽입앵커(11)는 대략 파이프의 형태를 취하며, 콘크리트구조물(17)의 상부로 노출되는 노출부(23)와 하부로 매입되는 매입부(25)로 나뉘어져 있다. 또한 상기 삽입앵커(11)의 상부에는 암나사부(15)가 형성되어 아이볼트(13)와 결합하도록 되어있다. 상기 아이볼트(13)는 크레인(미도시)의 인양고리에 걸리는 볼트로서 암나사부(15)와 나사결합한 상태로 들어올려진다.Referring to the drawings, the conventional insertion anchor 11 takes the form of a pipe, and is divided into an exposed portion 23 exposed to the upper portion of the concrete structure 17 and a buried portion 25 embedded into the lower portion. In addition, the upper part of the insertion anchor 11 is formed with a female screw portion 15 is to be coupled to the eye bolt (13). The eye bolt 13 is lifted in a state of being screwed with the female screw portion 15 as a bolt that is caught by the lifting ring of the crane (not shown).
상기 삽입앵커(11)의 매입부(25)에는 관통공(21)이 형성되어 있다. 상기 관통공(21)은 콘크리트구조물(17)내에 설치되는 철근(19)이 관통하는 구멍이다.The through hole 21 is formed in the embedding portion 25 of the insertion anchor 11. The through hole 21 is a hole through which the reinforcing bar 19 installed in the concrete structure 17 penetrates.
상기와 같이 이루어지는 종래의 콘크리트구조물 인양용 삽입앵커는 수직의 파이프의 형태를 취하므로, 콘크리트구조물(17)과 삽입앵커(11)사이의 고정력이 약하다는 문제가 있다. 콘크리트구조물(17)의 무게가 수십 톤에 달하는 것도 있으므로, 콘크리트구조물(17)과 삽입앵커(11)와의 분리는 매우 위험하고 작업자의 생명까지 위협할 수 도 있다. 즉 콘크리트구조물(17)을 제작할 때에 콘크리트의 양생이 불충분할 경우 삽입앵커(11)와 콘크리트구조물(17)간에는 미세한 틈이 발생할 수 있고 또한 양성된 콘크리트구조물(17)을 운반중 야기되는 외부의 충격이나 진동에 의해 삽입앵커가 콘크리트구조물(17)로부터 쉽게 분리될 수 도 있다는 문제가 있다.Conventional concrete structure lifting insertion anchor made as described above takes the form of a vertical pipe, there is a problem that the fixing force between the concrete structure 17 and the insertion anchor 11 is weak. Since the weight of the concrete structure 17 may be several tens of tons, the separation between the concrete structure 17 and the insertion anchor 11 is very dangerous and may even threaten the life of the worker. That is, when the curing of concrete is insufficient when the concrete structure 17 is manufactured, a fine gap may occur between the insertion anchor 11 and the concrete structure 17 and an external impact caused during transportation of the nurtured concrete structure 17. However, there is a problem that the insertion anchor may be easily separated from the concrete structure 17 by vibration.
본 고안은 상기 문제점을 해소하고자 안출한 것으로서, 콘크리트구조물의 내부에 매입되는 매입부의 하단부를 길이방향으로 분할하고 절곡시켜, 콘크리트구조물로부터 삽입앵커가 분리되지 않도록 형성한 콘크리트구조물 인양용 삽입앵커를 제공함에 제 1의 목적이 있다. 또한 삽입앵커의 상단부에 별도의 인양용후크를 고정시켜 아이볼트가 없을 때에도 구조물의 인양을 할 수 있고 더 나아가 매입부의 관통공을 복수개 형성하여 구조물내에 매입된 철근에 의해 보다 견고히 지지되도록 형성된 콘크리트구조물 인양용 삽입앵커를 제공함에 제 2의 목적이 있다.The present invention has been made to solve the above problems, by dividing and bending the lower end of the buried portion embedded in the concrete structure in the longitudinal direction, to provide an insertion anchor for lifting the concrete structure formed so that the insertion anchor is not separated from the concrete structure. Has a primary purpose. In addition, it is possible to lift the structure even when there is no eye bolt by fixing a separate lifting hook on the upper end of the insertion anchor. Furthermore, the concrete structure is formed to be more firmly supported by the reinforcing bars embedded in the structure by forming a plurality of through holes in the buried part. It is a second object to provide a lifting anchor for lifting.

도면을 참조하면, 본 실시예에 따른 콘크리트구조물 인양용 삽입앵커(51)는 콘크리트구조물(도 3의 17)의 외부로 돌출되는 노출부(53)와 내부에 매입되는 매입부(55)로 이루어진다.Referring to the drawings, the concrete structure lifting insertion anchor 51 according to the present embodiment consists of an exposed portion 53 protruding to the outside of the concrete structure (17 of FIG. 3) and a buried portion 55 embedded therein. .
상기 노출부(53)는 파이프의 형태를 취하며 암나사부(15)가 형성되어 있다. 상기 암나사부(15)는 아이볼트(도 3의 13)가 결합하도록 암나사가 형성되어 있는 부위이다. 상기 아이볼트(13)는 암나사부에(15)에 결합한 상태로 인양고리(도 4의 61)에 걸려 크레인의 동작에 따라 인양된다.The exposed portion 53 takes the form of a pipe and has a female threaded portion 15 formed therein. The female screw portion 15 is a portion where the female screw is formed so that the eye bolt (13 in Figure 3) is coupled. The eye bolt 13 is lifted in accordance with the operation of the crane hanging on the lifting ring (61 in Fig. 4) in a state coupled to the female threaded portion (15).
상기 매입부(55)는 노출부(53)와 일체로 형성되어 있으며, 중앙부에 관통공(21)이 형성되어 있다. 상기 관통공(21)은 삽입앵커(51)가 콘크리트구조물(17)내에 고정될 때에 철근이 관통하는 구멍이다. 상기 관통공(21)의 하부에는 절곡부(57)가 위치한다. 상기 절곡부(57)는 매입부(55)를 길이방향으로 절개하여 상호 반대편으로 절곡시킨 부위로서 상기 절곡부(57)는 노출부(53)에 대해서 대략 직각의 각을 이룬다. 상기 절곡부(57)의 수평길이 L은 삽입앵커(51)의 수직높이(h)의 1/4 내지 1/3의 길이를 갖도록 할 수 있다.The buried portion 55 is formed integrally with the exposed portion 53, the through hole 21 is formed in the center portion. The through hole 21 is a hole through which steel reinforces when the insertion anchor 51 is fixed in the concrete structure 17. The bent portion 57 is positioned below the through hole 21. The bent portion 57 is a portion in which the buried portion 55 is cut in the longitudinal direction and bent in opposite directions. The bent portion 57 forms an approximately right angle with respect to the exposed portion 53. The horizontal length L of the bent portion 57 may have a length of 1/4 to 1/3 of the vertical height h of the insertion anchor 51.
도 3은 본 고안의 제 1실시예에 따른 삽입앵커를 콘크리트구조물에 적용한 모습을 도시한 절제 사시도이다.3 is a cutaway perspective view illustrating a state in which the insertion anchor according to the first embodiment of the present invention is applied to a concrete structure.
도면을 참조하면, 삽입앵커(51)의 노출부(53)는 콘크리트구조물(17)의 상면으로부터 외부로 돌출되어 있으며 아이볼트(13)과 결합함을 알 수 있다. 또한, 매입부(55)는 콘크리트구조물(17)의 내부에 고정되어 있다. 상기 매입부(55)는 콘크리트구조물(17)을 양생시에 삽입앵커(51)을 일정높이로 지지시킨 상태로 굳혔을 때에 콘크리트구조물(17)내에 매입되는 부위임은 상기한 바와같다.Referring to the drawings, it can be seen that the exposed portion 53 of the insertion anchor 51 protrudes outward from the upper surface of the concrete structure 17 and engages with the eye bolt 13. In addition, the buried portion 55 is fixed inside the concrete structure 17. The embedding part 55 is a portion to be embedded in the concrete structure 17 when the concrete structure 17 is hardened in a state in which the insertion anchor 51 is supported at a predetermined height during curing.
아울러, 콘크리트구조물(17)내에 상기 삽입앵커(51)를 설치할 때에 매입부(55)에 형성되어 있는 관통공(21)에는 철근(19)을 관통시킨다. 이와같이 삽입앵커(51)와 철근(19)을 엮어놓는 것은 인양작업 중 삽입앵커(51)부위의 콘크리트구조물(17)이 깨지더라도 삽입앵커(51)가 철근(19)을 통하여 콘크리트구조물(17)을 지지할 수 있도록 하기 위한 것이다.In addition, when the insertion anchor 51 is installed in the concrete structure 17, the reinforcing bar 19 passes through the through hole 21 formed in the embedding portion 55. In this way, weave the insertion anchor 51 and the reinforcing bar 19, even if the concrete structure 17 of the insertion anchor 51 portion breaks during the lifting operation, the insertion anchor 51 through the reinforcing bar (19) concrete structure (17) It is intended to support this.

Each of the insertion anchors 63 has a lifting hook 61 of the crane hung by a lifting rope 59. On the left side of the drawing, the lifting anchor 61 is attached to the lifting hook 65. It can be seen that the lifting ring 61 is hung on the eye bolt 13 at the insertion anchor 63 on the right side. As described above, the insertion anchor 63 according to the second embodiment may be used by applying the eye bolt 13, or in the absence of the eye bolt 13, may be used by hanging directly on the lifting hook 65. It is.
도 7은 본 고안의 제 3실시예에 따른 콘크리트구조물 인양용 삽입앵커를 도시한 사시도이다.7 is a perspective view showing the insertion anchor for lifting a concrete structure according to a third embodiment of the present invention.
도면을 참조하면, 본 실시예에 따른 삽입앵커(67)에는 매입부(55)에 관통공(21)이 두 개가 형성되어 있음을 알 수 있다. 상기한 바와같이 관통공(21)은 삽입앵커(67)가 콘크리트구조물(17)내에 설치될 때에 구조물내의 철근이 관통되도록 형성한 구멍이다. 관통공(21)이 두 개가 형성되어 있으므로 삽입앵커(67)에는 두 가닥의 철근(19)과 결합할 수 있어 보다 큰 지지력을 제공할 수 있는 것이다.Referring to the drawings, it can be seen that the insertion anchor 67 according to the present embodiment has two through-holes 21 formed in the embedding portion 55. As described above, the through hole 21 is a hole formed so that the rebar in the structure penetrates when the insertion anchor 67 is installed in the concrete structure 17. Since two through-holes 21 are formed, the insertion anchors 67 can be combined with two reinforcing bars 19 to provide greater support.
도 8은 본 고안의 제 3실시예에 따른 콘크리트구조물 인양용 삽입앵커가 적용된 콘크리트구조물을 인양하는 모습을 도시한 도면이다.8 is a view showing a lifting state of the concrete structure applied to the lifting structure insertion anchor for the concrete structure according to the third embodiment of the present invention.
상기한 도면부호와 동일한 도면부호는 동일한 기능의 동일한 부재를 가리킨다.The same reference numerals as the above reference numerals denote the same members having the same function.
도면을 참조하면, 삽입앵커(67)에 두 가닥의 철근(19)이 연결되어 있음을 알 수 있다. 따라서 예를들어 콘크리트구조물의 삽입앵커(67)부위가 깨지더도 삽입앵커(67)가 철근(19)를 통해 콘크리트구조물(17)을 계속 지지할 수 있으므로 구조물(17)의 낙하의 위험성이 없다.Referring to the drawings, it can be seen that the two reinforcing bar 19 is connected to the insertion anchor (67). Thus, for example, even if the insertion anchor 67 portion of the concrete structure is broken, the insertion anchor 67 can continue to support the concrete structure 17 through the reinforcing bar 19, there is no risk of falling of the structure 17.
상기 제 2실시예와 제 3실시예를 동시에 구현하여 인양용후크(65)와 복수의 관통공(21)이 동시에 구비된 삽입앵커를 제작할 수 도 있음은 물론이다.By implementing the second embodiment and the third embodiment at the same time it is also possible to manufacture the insertion anchor provided with the lifting hook 65 and the plurality of through-holes 21 at the same time.
이상, 본 고안을 구체적인 실시예를 통하여 상세하게 설명하였으나, 본 고안은 상기한 실시예에 한정되지 않고, 본 고안의 기술적 사상의 범위내에서 통상의 지식을 가진 자에 의하여 여러 가지 변형이 가능하다.The present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. .
상기와 같이 이루어지는 본 고안의 콘크리트구조물 인양용 삽입앵커는, 콘크리트구조물의 내부에 매입되는 매입부의 하단부가 절곡되어 있으므로, 삽입앵커와 콘크리트구조물의 결합이 견고하다. 따라서 콘크리트구조물에 외부의 충격이나 진동등의 외력이 가해지더라도 콘크리트구조물과 삽입앵커가 분리될 염려가 없다. 또한 삽입앵커의 상단부에 별도의 인양용후크를 구비할 수 도 있어 아이볼트가 없을 때에도 구조물의 인양을 할 수 있고 더 나아가 매입부의 관통공을 복수개 형성하여 구조물내에 매입된 철근과 삽입앵커와의 결합을 보다 견고히 할 수 있다는 효과가 있다.Insertion anchor for lifting a concrete structure of the present invention made as described above, because the lower end of the buried portion embedded in the interior of the concrete structure is bent, the combination of the insertion anchor and the concrete structure is firm. Therefore, even if an external force such as external impact or vibration is applied to the concrete structure, the concrete structure and the insertion anchor are not separated. In addition, a separate lifting hook may be provided at the upper end of the insertion anchor to lift the structure even when there is no eye bolt, and further, to form a plurality of through holes in the buried portion to couple the reinforcement embedded in the structure with the insertion anchor. There is an effect that can be more solid.
