Description
본 발명은 콘크리트 구조물의 안전앵커 및 이를 이용한 시공방법에 대한 것으로서, 좀 더 상세히는 콘크리트 구조물의 시공시에 콘크리트 슬래브의 저면에 매입 설치하여 작업자를 안전하게 매달 수 있도록 된 새로운 구조의 콘크리트 구조물의 안전앵커 및 이를 이용한 시공방법에 대한 것이다.The present invention relates to a safety anchor of a concrete structure and a construction method using the same, in more detail, the safety anchor of a concrete structure of a new structure that can be securely suspended by the operator installed on the bottom of the concrete slab during construction of the concrete structure And to a construction method using the same.
콘크리트 구조물을 시공하기 위해서는 거푸집을 시공하고 거푸집 내부에 철근을 배근하고, 레미콘을 타설하여 양생시켜서 콘크리트 구체를 완성하게 된다. 콘크리트 구체가 시공되면, 배관공사나 발코니의 섀시나 창호 등의 후속 공사를 수행하게 된다. 그런데, 종래에 이와 같이, 고층건물의 콘크리트 구체공사를 마친 후에는, 베란다용 개구부나 엘리베이터 피트, 계단실 등과 같이 건물에 형성되는 많은 개구부가 작업자에게 그대로 노출되므로, 섀시나 창호 또는 배관공사를 할 때, 실족으로 인한 추락사고 등의 안전사고의 우려가 높다. 비록 안전을 위해서 추락방지용 안전 펜스나 낙하방지망 등의 안전구조물을 설치하더라도, 이러한 안전구조물들은 임시로 설치한 가설구조물인 만큼, 영속적인 구조물과 같이 필요한 위치마다 충분히 견고하게 설치될 수는 없기 때문에, 이러한 가설용 안전구조물만으로는 안전에 대한 충분한 대비가 되지 못하는 문제점이 있었다.In order to construct the concrete structure, construct the formwork, reinforce the reinforcement inside the formwork, and cast concrete to finish the concrete sphere. When the concrete sphere is constructed, the plumbing work or the subsequent work such as the chassis or windows of the balcony is performed. However, in the past, after finishing concrete construction of a high-rise building, many openings formed in the building, such as porch openings, elevator pits, and staircases, are exposed to the workers as they are. There is a high risk of a safety accident such as a fall caused by a loss of life. Although safety structures such as fall protection fences and drop protection nets are installed for safety reasons, these safety structures are temporary constructions that are temporarily installed. There is a problem that the safety structure for the hypothesis alone is not enough prepared for safety.

이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다. 도 1은 본 발명의 바람직한 실시예에 따른 안전용 앵커의 외관도이고, 도 2는 이의 시공상태도이며, 도 3은 이의 사용상태도이다. 도시된 바와 같이, 본 발명에 따르면, 봉형상의 바디(1)의 일단에 횡방향으로 관통된 관통공(12)이 형성되고, 타단에는 축방향으로 탭가공된 나사축공(14)이 형성되어, 그 내부에는 암나사부(15)가 형성된 안전앵커가 제공된다. 이러한 안전앵커에는 숫나사부(22)가 형성된 고리부재(20), 또는 이른바 아이볼트가 결합되어 사용되게 된다. 상기 봉형상의 바디는 원통형으로 도시되었으나, 단면이 사각형 육각형 기타의 다각형의 형태로 제작될 수 있으며, 더욱 바람직하게는 콘크리트와의 부착강도를 높이기 위해 그 둘레부에 돌기나 요철부를 형성할 수도 있음은 물론이다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. 1 is an external view of a safety anchor according to a preferred embodiment of the present invention, Figure 2 is a construction state diagram thereof, Figure 3 is a use state diagram thereof. As shown, according to the present invention, a through hole 12 penetrated in the transverse direction at one end of the rod-shaped body 1 is formed, the other end is formed with a screw shaft hole 14 tapped in the axial direction, Inside there is provided a safety anchor with a female threaded portion (15). In the safety anchor, the male member 22 is formed with a ring member 20, or a so-called eye bolt. Although the rod-shaped body is shown in a cylindrical shape, the cross section may be manufactured in the form of a polygonal hexagon and other polygons, and more preferably, protrusions or irregularities may be formed at the periphery thereof to increase adhesion strength with concrete. Of course.
도 2를 참조하면, 본 발명에 따른 콘크리트 구조물의 슬래브 구조를 보여주는데, 도시된 바와 같이, 슬래브(1)를 시공하기 위해 수평방향의 슬래브 거푸집(4)이 형성되고, 그 위에 수평방향의 철근(6) 및 기타 철근이 배근되며, 그 위에 콘크리트(8)가 타설된다. 이 때, 본 발명의 안전앵커는 일단의 횡방향 관통공(12)이 슬래브 거푸집(4)으로부터 일정거리 만큼 이격된 수평방향 철근(6)에 관통되고, 그 타단의 나사축공(14)은 슬래브 거푸집(4)의 상면에 접촉되도록 수직 배치되어 지지된다. 이러한 본 발명에 따르면, 간단한 구조의 안전앵커가 철근(6)에 용이하게 삽입되어 시공될 수 있으므로 설치 및 시공이 편리하다. 이 안전앵커는 대체로 상기 수평철근(6)에 관통되어 지지되는 것이지만, 시공여건이 이를 허락하지 않는 경우에는 별도로 수평방향의 핀부재를 설치하여 이에 안전앵커를 끼울 수 있음은 물론이다. 아울러, 안전앵커의 나사축공(14)에는 도시 안된 보호캡 또는 부가물이 결합되어 시공시에, 슬래브 거푸집(4)의 상면에서 안정되게 정위치에 유지되도록 할 수도 있음은 물론이다.Referring to Figure 2, showing a slab structure of a concrete structure according to the present invention, as shown, a horizontal slab formwork (4) is formed for the construction of the slab (1), the horizontal reinforcement ( 6) and other reinforcing bars are laid, on which concrete (8) is poured. At this time, the safety anchor of the present invention is passed through the horizontal reinforcing bar 6, one end of the transverse through-hole 12 spaced apart from the slab formwork 4 by a predetermined distance, the screw shaft hole 14 of the other end is slab It is vertically arranged and supported to be in contact with the upper surface of the formwork 4. According to the present invention, since the safety anchor of a simple structure can be easily inserted and installed in the reinforcing bar 6, the installation and construction is convenient. This safety anchor is generally supported to penetrate the horizontal reinforcement (6), but if the construction conditions do not allow this, it is a matter of course that the safety anchor can be fitted to it by installing a horizontal pin member separately. In addition, the screw shaft hole 14 of the safety anchor is combined with a protective cap or an additive (not shown) may be of course to be maintained in a stable position on the upper surface of the slab formwork 4 during construction.
이러한 구조에 따르면, 나중에 콘크리트가 경화되어 슬래브 거푸집(4)을 제거하면, 안전앵커의 나사축공(14)이 슬래브의 저면, 즉 천정면에 노출된다. 그러면 아이볼트와 같이 숫나사부(22)가 형성된 고리부재(20)를 나사결합할 수 있고, 작업자는 이 고리부재(20)에 안전용 로프(2)를 끼워서 자신을 결속한 상태에서, 베란다 섀시나 창호공사 또는 배관공사 등의 후속작업을 수행할 수 있다. 이러한 구조에 의하면 콘크리트 구체 공사 이후의 후속작업에서, 실족이나 추락 등의 안전사고를 더욱 효과적으로 방지할 수 있기 때문에, 공사현상의 산업재해를 더욱 낮출 수 있다. 이러한 본 발명의 안전앵커는, 콘크리트 구조물인 아파트 베란다, 창호용 개구부, 엘리베이터 피트나 계단실과 같이, 실족이나 추락의 위험성이 높은 개구부에 인접한 슬래브 부분에 매입설치함으로써, 이러한 위험한 장소에서의 안전사고를 효과적으로 방지할 수 있다. According to this structure, when the concrete is later hardened to remove the slab formwork 4, the screw shaft holes 14 of the safety anchor are exposed on the bottom surface of the slab, that is, the ceiling surface. Then, it is possible to screw the ring member 20 in which the male threaded portion 22 is formed like an eye bolt, and the worker inserts the safety rope 2 into the ring member 20 to bind itself to the veranda chassis. B) Follow-up work such as window construction or plumbing may be performed. According to such a structure, in the subsequent work after concrete concrete construction, safety accidents such as loss or fall can be prevented more effectively, so that industrial accidents in construction can be further lowered. The safety anchor of the present invention is installed in a slab portion adjacent to an opening having a high risk of loss or fall, such as an apartment porch, a window opening, an elevator pit or a staircase, which is a concrete structure, thereby preventing a safety accident in such a dangerous place. Can be effectively prevented.
이상에서 설명한 본 발명에 따르며, 일단에 횡방향 관통공(12)이 형성되고 타단에는 축방향 나사축공(14)이 형성된 안전앵커를 콘크리트 구조물의 베란다나 창호, 또는 엘리베이터나 계단실 등의 개구부 근처의 슬래브의 저면에 매입하여 두면, 작업자가 이에 안전고리를 나사결합하여, 안전용 로프를 매달아서 결속할 수 있으므로, 공사현상의 실족이나 추락 등의 안전사고를 대폭 줄일 수 있다.According to the present invention described above, the safety anchor formed with a transverse through hole 12 at one end and an axial screw shaft hole 14 at the other end is located near a porch or window of a concrete structure or near an opening such as an elevator or a staircase. If the slab is placed on the bottom of the slab, the worker can screw the safety ring and hang the safety rope to bind it, thereby greatly reducing the safety accidents such as loss of work or fall.
더욱이 본 발명에 따르면, 봉형상 바디(10)의 일단에 횡방향 관통공(12)를 형성하고 타단에는 축방향 나사축공(14)을 탭가공한 간단한 구조이므로 제작이 용이하고, 시공시에는 안전앵커의 관통공(12)을 슬래브의 수평방향 철근(6)에 간단하게 끼워서 사용할 수 있으므로, 매입시공도 매우 간단하게 이루어질 수 있다. Furthermore, according to the present invention, since the transverse through-hole 12 is formed in one end of the rod-shaped body 10 and the other end is a simple structure in which the axial screw shaft hole 14 is tabbed, it is easy to manufacture, and is safe during construction. Since the through hole 12 of the anchor can be simply inserted into the horizontal reinforcing bar 6 of the slab, the embedding construction can be made very simple.
