Description

상하근 겸용 철근조립용스페이스{Combined Upper and Lower Rebar Spacer}Combined Upper and Lower Rebar Spacer}

본 발명은 상근과 하근을 동시에 지지하는데 이용할 수 있는 상하근 겸용 철근조립용스페이스에 관한 것으로, 더욱 상세하게는 철근 콘크리트(RC, Reinforced Concrete)의 슬래브에 사용되는 상근(상부철근)과 하근(하부철근)의 교차부위에 적용할 수 있도록 한 상하근 겸용 철근조립용스페이스에 관한 것이다.The present invention relates to a space for assembling up and down reinforcing bars that can be used to simultaneously support the upper and lower muscles, and more specifically, the upper and upper (upper reinforcing bar) and lower (lower part) used for slab of reinforced concrete (RC, Reinforced Concrete) It relates to a space for reinforcing bar reinforcing bars, which can be applied to intersections of rebars).

일반적으로 철근 콘크리트 건축물에 사용되는 철근은 콘크리트 타설시 철근과 거푸집사이로 골재 유동성을 확보하고, 대기중 수분에 의한 부식에 취약한 철근이 대기와 접촉되는 것을 차단하기 위해 콘크리트에 의해 적절한 두께로 피복되어야 한다.In general, reinforcing steel used in reinforced concrete buildings should be covered with the appropriate thickness by concrete to secure aggregate fluidity between reinforcing steel and formwork and to prevent the reinforcing steel, which is susceptible to corrosion by moisture in the air, to contact the atmosphere. .

또한, 철근은 고온(약 600도)에서 급격한 강도저하(항복점의 약 1/2로 떨어짐)가 발생되기 때문에 화재시 철근이 화기에 직접적으로 노출되지 않도록 하기 위해 적절한 철근의 콘크리트 피복두께 확보는 건축물 안전에 더욱 중요하게 된다.In addition, since reinforcing bars are subjected to a sharp drop in strength (approximately 1/2 of the yield point) at high temperatures (about 600 degrees), it is necessary to secure the appropriate concrete cover thickness of the reinforcing bars in order to prevent the reinforcing bars from being directly exposed to fire. It becomes more important for safety.

위와 같이 철근의 피복두께확보를 위해 슬래브, 벽체, 기둥, 보에 사용되는 각종 철근과 거푸집 사이에 위치되어 간격을 일정하게 유지시켜 주는 철근조립용스페이스가 사용된다. 이와 같은 철근조립용스페이스는 플라스틱, 고강도 콘크리트 또는 모르타르, 강봉, 강판 등으로 제조된다.In order to secure the cover thickness of the reinforcing bar as described above, a space for reinforcing bars is used between the various rebars and formwork used in slabs, walls, columns, and beams to maintain a constant gap. Such rebar assembly space is made of plastic, high-strength concrete or mortar, steel rods, steel sheets, and the like.

그러나, 종래 철근조립용스페이스는 철근배근 작업 중 또는 콘크리트 타설작업 중에 측면에서 외력이 작용되면 전도되는 문제점이 있었으며, 특히 상근받침대의 경우 좌우폭에 비해 키가 높기 때문에 약간의 힘으로도 쉽게 넘어지는 문제점이 있었다.However, the conventional reinforcing bar space has a problem in that when the external force is applied from the side during the reinforcement or concrete placement work, especially the height of the full support but fall easily with a slight force because the height is higher than the left and right width There was this.

이와 같이 철근조립용스페이스가 전도되면 콘크리트 피복두께를 확보하지 못해 화재시 구조물의 급격한 강도저하가 염려되며, 대기중에 노출된 철근은 부식이 빠르게 진행되어 콘크리트 건축물의 수명을 단축시키는 문제점을 유발시키게 되고, 콘크리트 타설시 골재의 이동에 장애가 되는 문제점이 발생된다. In this way, when the reinforcing space for reinforcing bars is conducted, the concrete cover thickness cannot be secured, which may cause a sudden drop in the strength of the structure.In the case of rebars exposed to the atmosphere, corrosion progresses rapidly, causing a problem of shortening the life of concrete buildings. , Problems occur that impede the movement of aggregates when placing concrete.

더욱이 콘크리트 타설작업 중에는 철근조립용스페이스가 눈에 보이지 않기 때문에 철근조립용스페이스의 전도를 발견할 수 없으므로, 콘크리트 타설작업전에 철근조립용스페이스가 넘어지지 않게 고정하는 것은 더욱 중요하게 된다.In addition, since the reinforcing space for reinforcing bars cannot be found during the reinforcing work, the reinforcing space for reinforcing bars is not found. Therefore, it is more important to fix the reinforcing space for reinforcing bars before the reinforcing work.

또한, 종래 철근조립용스페이스는 철근의 교차부위에 시공하는 것이 곤란하며, 교차부위에 시공하도록 만들어진 종래 철근조립용스페이스는 상근과 하근이 수직선상에 위치되지 않고 좌우방향으로 약간 어긋나게 위치되는 곳에 적용할 수 밖에 없는 단점이 있었다.In addition, the conventional reinforcing bar space is difficult to be installed at the intersection of the reinforcing bars, the conventional reinforcing bar space made to be installed at the intersection is applied where the upper and lower muscles are located slightly shifted in the left and right direction instead of being located on the vertical line There was a disadvantage to be forced.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 철근 콘크리트 건축물에 사용되는 상근과 하근을 동시에 지지하고, 상근 및 하근의 교하부위에 적용할 수 있으며, 시공이 간편한 상하근 겸용 철근조립용스페이스를 제공함에 있다.The present invention has been made to solve the above problems, the object of which is to support the upper and lower muscles used in reinforced concrete buildings at the same time, can be applied to the lower and lower bridges of the upper and lower muscles, easy to use the upper and lower reinforcing bars To provide a space for assembly.

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 내지 도5에 도시된 바와 같이 하부슬리브(32)를 사이에 두고 하부볼트(33)와 하부너트(34)에 의해 결합된 하근받침판(30)(31)을 거푸집(100) 위에 놓고 하근받침판(30)(31)의 상단 중앙에 형성된 하근받침홈(35)에 하근(81)을 올려놓게 되면, 하근받침판(30)(31)에 의해 하근(81)이 거푸집(100)으로부터 일정한 높이에 위치된다.As shown in FIGS. 1 to 5, the lower back support plate 30 and 31 coupled by the lower bolt 33 and the lower nut 34 with the lower sleeve 32 interposed therebetween on the formwork 100. Place the lower root 81 on the lower back support groove 35 formed in the upper center of the lower back support plate 30, 31, the lower root 81 by the lower back support plate 30, 31 from the die 100 It is located at a constant height.

이후 하근(81) 위에 열십자로 올려지는 교차하근(83)을 설치하면서 하근받침판(30)(31) 사이에 교차하근(83)을 위치시키게 되면, 하근받침판(30)(31)이 하부슬리브(32)에 의해 이격되어 있기 때문에 교차하근(83)이 하근받침판(30)(31)에 간섭되지 않게 된다.After placing the cross roots 83 between the inferior support plates 30 and 31 while installing the cross roots 83 that are raised crosswise over the inferior muscles 81, the inferior support plates 30 and 31 are lower sleeves ( Since it is spaced apart by the 32) intersected lower muscle 83 is not interfered with the lower support plate 30, 31.

그 다음 상부슬리브(42)를 사이에 두고 상부볼트(43)와 상부너트(44)에 의해 결합된 상근받침판(40)(41)을 하근받침판(30)(31)에 결합하기 위해 하근받침판(30)(31)과 상근받침판(40)(41)을 평면상에서 볼 때 열십자모양을 이루도록 한 상태에서 상근받침판(40)(41)의 하단에 형성된 상향끼움홈(46)(47)을 하근받침판(30)(31)의 상단에 형성된 하향끼움홈(36)(37)에 일치시키고, 상근받침판(40)(41)을 하근받침판(30)(31)에 결합하게 되면, 상향끼움홈(46)(47)과 하향끼움홈(36)(37)이 맞물려 결합된다.Then, the upper support plate (40) and the upper support plate (40) (41) coupled by the upper bolt 43 and the upper nut (44) in between the lower support plate (30) (31) for coupling 30) (31) and the upper support plate (40) (41) in a state of making a cross shape when viewed in plan view the upper fitting groove (46) (47) formed at the bottom of the upper support plate (40) (41) Matching with the downward fitting grooves 36 and 37 formed at the upper ends of the supporting plates 30 and 31, and when the upper and lower support plates 40 and 41 are coupled to the lower support plates 30 and 31, the upward fitting grooves ( 46 and 47 and the down fitting grooves 36 and 37 are engaged with each other.

이때 상근받침판(40)(41)의 하단부가 거푸집(100)에 밀착되면서 상근받침판(40)(41)에 작용되는 하중이 거푸집(100)으로 직접 전달된다.At this time, the lower end of the full support plate 40, 41 is in close contact with the formwork 100, the load acting on the full support plate 40, 41 is transmitted directly to the formwork (100).

위와 같이 하근받침판(30)(31)에 상근받침판(40)(41)이 교차되게 조립된 상태에서 상근받침판(40)(41)의 상단 중앙에 형성된 상근받침홈(45)에 상근(80)을 끼워서 지지하기 위해 상근(80)을 철근이탈방지클립(51)(52)으로 삽입하게 되면, 철근이탈방지클립(51)(52)에 형성된 경사날개부(70)(71)가 바깥쪽으로 벌어지면서 상근(80)의 진입을 돕게 되며, 상근(80)이 철근이탈방지클립(51)(52)의 안쪽으로 진입되면, 경사날개부(70)(71)는 탄성복원력에 의해 안쪽으로 오am라들면서 상근(80)의 이탈을 방지하게 된다.Upper 80 in the vertical support groove 45 formed in the upper center of the upper support plate 40, 41 in the state that the upper support plate 40, 41 is assembled to cross the lower support plate 30, 31 as described above When inserting the upper arm 80 into the reinforcement release prevention clip (51) (52) to insert the support, the inclined wings (70) (71) formed on the reinforcement release prevention clip (51) (52) is opened to the outside Helping the entry of the upper arm 80, and when the upper arm 80 enters the inside of the rebar release prevention clip (51) (52), the inclined wing (70) (71) is inward by the elastic restoring force The ladle prevents the departure of the upper arm 80.

이후 상근(80) 위에 열십자모양으로 올려지는 교차상근(82)을 상근(80)에 올리면서 상근받침판(40)(41) 사이 정중앙에 위치시키게 되면, 철근이탈방지클립(51)(52)의 사이에 위치된 간격재(50)에 의해 교차상근(82)이 철근이탈방지클립(51)(52)에 간섭되지 않고 위치된다.After placing the cross-upright 82 raised in a cross shape over the full-length 80 on the upper-right 80, while being placed in the center of the upper-back support plate 40, 41, reinforcement prevention prevention clip (51) (52) By the spacer 50 positioned between the intersecting upper muscle 82 is positioned without interfering with the rebar departure prevention clip (51) (52).

한편, 철근 배근작업 또는 콘크리트 타설작업 중에 상근받침판(40)(41)의 좌우방향으로 외력이 작용되면, 상근받침판(40)(41)의 하단부 폭이 비교적 넓게 형성되어 있기 때문에 좌우방향으로 작용되는 외력에 대해서 안정성이 확보되며, 상근받침판(40)(41)의 전후방향으로 외력이 작용되는 경우에는 상근받침판(40)(41)과 하근받침판(30)(31)이 하향끼움홈(36)(37)과 상향끼움홈(46)(47)에 의해 교차로 결합되어 있기 때문에 전후방향으로 길게 되어 있는 하근받침판(30)(31)에 의해 상근받침판(40)(41)이 넘어지지 않게 된다.On the other hand, when the external force is applied in the left and right direction of the full support plate 40, 41 during the reinforcement reinforcement work or concrete pouring work, because the width of the lower end of the full support plate 40, 41 is formed relatively wide, it acts in the left and right direction Stability is secured against external force, and when the external force is applied in the front and rear directions of the full support plate 40, 41, the full support plate 40, 41 and the bottom support plate 30, 31 are fitted downward. Since the 37 and the upward fitting grooves 46 and 47 are intersected with each other, the full support plates 40 and 41 do not fall by the lower support plates 30 and 31 which are elongated in the front and rear directions.
