본 발명은 설치와 해체가 신속하고 용이하게 이루어지고 바닥면에서 다면 및 천정부를 갖는 콘크리트 구조물의 제작이 가능하도록 한 콘크리트용 거푸집에 관한 것이다.The present invention relates to a formwork for concrete that allows for the quick and easy installation and dismantling and the production of concrete structures with multi-facets and ceilings at the bottom.
일반적으로 콘크리트 구조물을 시공하는 경우에는 철근골조의 외측에 다수의 거푸집을 마주보게 설치하고 마주본 상태의 거푸집 사이의 빈공간에 콘크리트를 타설하고 양생시킨다. 이때, 상기 거푸집들은 별도의 연결장치에 의해 서로 연결된다.In general, when constructing a concrete structure, a plurality of formwork is installed to face the outer side of the reinforcing bar, and concrete is placed and cured in the empty space between the formwork facing each other. At this time, the formwork is connected to each other by a separate connection device.
도 1 및 도 2에 도시된 바와 같이, 종래의 콘크리트용 거푸집은 시공 바닥면에 고정되는 내측바닥지지대(10a)와 외측 바닥지지대(10b)와, 상기 바닥지지대들(10a,10b)의 상부에 일정간격으로 설치되는 거푸집 패널(1)과, 상기 거푸집 패널(1)들의 연결부 외측을 지지하는 수직지지대(20)와, 상기 수직지지대(20)와 마주보도록 상기 거푸집 패널(1)의 내측에 위치되는 밀착부재(30)와, 상기 밀착부재(30)와 수직지지대(20)가 거푸집 패널(1)에 긴밀히 밀착되도록 하는 조임수단(40)으로 구성된다.As shown in Figures 1 and 2, the conventional formwork for concrete has an inner bottom support (10a) and an outer bottom support (10b) fixed to the construction floor surface, and on the top of the bottom supports (10a, 10b) The formwork panel 1 which is installed at a predetermined interval, the vertical support 20 for supporting the outside of the connecting portion of the formwork panel 1, and the inner side of the formwork panel 1 so as to face the vertical support 20 The contact member 30 is formed, and the contact member 30 and the vertical support 20 is composed of a fastening means 40 to closely contact the formwork panel (1).
상기 바닥지지대(10)는 볼트에 의해 바닥에 견고하게 고정되며, 그 상부에는 상기 수직지지대(20)가 설치되도록 양측에 벽면을 가지는 거치대(11)가 구비된다. 상기 수직지지대(20)는 이 거치대(11)를 통해 바닥지지대(10)에 일정간격으로 수직하게 세워진다.The bottom support 10 is firmly fixed to the floor by bolts, and a cradle 11 having walls on both sides thereof is provided at the top thereof so that the vertical support 20 is installed. The vertical support 20 is erected perpendicularly to the floor support 10 through this holder (11).
한편, 콘크리트가 양생된 후 콘크리트 벽면 표면에 밀착부재(30)로 인한 턱이 발생하는 것을 방지하기 위하여 거푸집 패널(1)의 내측면에는 밀착부재(30)의 두께와 동일한 깊이의 안착홈(2)이 형성되며, 상기 밀착부재(30)는 안착홈(2)을 통해 거푸집 패널(1) 내측면과 동일면을 이루면서 밀착된다.On the other hand, in order to prevent the occurrence of the jaw due to the contact member 30 on the concrete wall surface after the curing of the concrete, the inner surface of the formwork panel (1) a mounting groove 2 of the same depth as the thickness of the contact member (30) ) Is formed, the contact member 30 is in close contact with the inner surface of the formwork panel 1 through the mounting groove (2).
또한, 상기 거푸집 패널(1)과 밀착부재(30)가 정확한 위치에서 결합되고 거푸집 패널(1)과의 결합력을 향상시킬 수 있도록 상기 각 거푸집 패널(1)의 내측면에는 거푸집 패널(1)의 길이방향을 따라 길게 요홈(2a)이 형성되고, 밀착부재(30)에는 상기 요홈(2a)에 대응되는 결합돌기(31)가 밀착부재(30)의 길이방향을 따라 형성된다.In addition, the formwork panel (1) and the close contact member 30 is coupled in the correct position and to improve the bonding force with the formwork panel (1) on the inner surface of each formwork panel (1) of the formwork panel (1) Grooves (2a) are formed long along the longitudinal direction, the engaging member 31 corresponding to the grooves (2a) is formed along the longitudinal direction of the contact member 30 in the contact member (30).
상기 조임수단(40)은 일단이 상기 수직지지대(20)를 향하는 밀착부재(30)의 전면에 밀착부재(30)의 길이방향을 따라 일정 간격으로 부착되고 타단이 수직지지대(20)를 관통하여 그 수직지지대(20)의 외부로 돌출되는 조임나사(41)와, 상기 수직지지대(20)의 외부로 돌출된 조임나사(41)의 단부에 체결되어 밀착부재(30)와 수직지지대(20)를 거푸집 패널(1)에 밀착시키는 조임너트(42)로 구성된다.The fastening means 40 is one end is attached to the front of the contact member 30 toward the vertical support 20 at regular intervals along the longitudinal direction of the contact member 30 and the other end penetrates through the vertical support 20 The fastening screw 41 protruding to the outside of the vertical support 20 and the end of the fastening screw 41 protruding to the outside of the vertical support 20 is fastened to the close contact member 30 and the vertical support 20 It consists of a tightening nut 42 for close contact with the formwork panel (1).
이와 같이 구성된 종래의 콘크리트 거푸집을 설치하기 위해서는 먼저, 바닥에 바닥지지대(10)를 고정시키고 상기 바닥지지대(10)의 상부에 구비된 거치대(11)에 거푸집 패널(1)을 설치한 다음, 거푸집 패널(1)의 연결부에 수직지지대(20)와 밀착부재(30)를 각각 설치한다. 이 과정에서 상기 밀착부재(30)에 구비된 조임나사(41)의 단부는 상기 수직지지대(20)를 관통하여 수직지지대(20)의 외부로 돌출된다.In order to install the conventional concrete formwork configured as described above, first, the bottom support 10 is fixed to the floor and the formwork panel 1 is installed on the pedestal 11 provided on the top of the bottom support 10, and then the formwork The vertical support 20 and the contact member 30 are respectively installed at the connection portion of the panel 1. In this process, the end of the tightening screw 41 provided in the close contact member 30 passes through the vertical support 20 to protrude out of the vertical support 20.
이 상태에서, 상기 조임나사(41)의 단부에 조임너트(42)를 체결시킨 다음 상기 조임너트(42)를 오른쪽으로 회전시키면, 상기 거푸집 패널(1)의 안착홈(2) 및 요홈(2a)으로 밀착부재(30)와 수직지지대(20)의 결합돌기(31)가 각각 안착되면서 밀착부재(30)와 수직지지대(20)가 거푸집 패널(1)의 양측면에 각각 견고하게 밀착되며, 이로써 거푸집 패널(1)은 안정적으로 연결된다.In this state, when the tightening nut 42 is fastened to the end of the tightening screw 41 and then the tightening nut 42 is rotated to the right, the seating groove 2 and the recess 2a of the formwork panel 1 are rotated. As the coupling member 31 of the contact member 30 and the vertical support 20 are respectively seated by), the contact member 30 and the vertical support 20 are firmly adhered to both sides of the formwork panel 1, thereby. The formwork panel 1 is connected stably.
이와 같은 방법에 의해 콘크리트 구조물의 일측 벽면을 형성할 수 있는 거푸집 패널이 연속적으로 연결된다.In this way, formwork panels that can form one side wall of the concrete structure are continuously connected.
상기와 같이 거푸집이 완성되면 콘크리트가 타설되고, 콘크리트의 양생이 끝나면 상기 거푸집 패널(1)은 해체되는데, 거푸집 패널(1)을 해체시키고자 할 때에는 상기 조임너트(42)를 왼쪽 방향으로 회전시켜 거푸집 패널(1)로부터 바닥지지대(10)와 거치대(11)를 해체시킬 수 있다. 이렇게 하면 콘크리트 구조물이 완성된다.When the formwork is completed as described above, the concrete is poured, and when the curing of the concrete is finished, the formwork panel 1 is dismantled. When the formwork panel 1 is to be dismantled, the tightening nut 42 is rotated to the left. The bottom support 10 and the holder 11 can be dismantled from the formwork panel 1. This completes the concrete structure.
그러나, 종래의 콘크리트용 거푸집은 다음과 같은 문제들을 갖는다.However, the conventional formwork for concrete has the following problems.
첫째, 종래의 콘크리트용 거푸집은 타설되는 콘크리트에 의해 발생되는 측압으로 인해 거푸집이 바깥쪽으로 밀리면서 완성되는 콘크리트 구조물의 수직도가 불량해지는 문제가 발생된다.First, the conventional formwork for concrete causes a problem that the verticality of the finished concrete structure is poor while the formwork is pushed outward due to the lateral pressure generated by the concrete being poured.
둘째, 종래의 콘크리트용 거푸집은 단일면의 콘크리트 벽체만을 제작할 수 있도록 되어 있어서 다면 벽체 즉 연결된 벽체의 제작이 매우 어렵다는 문제가 있다. 특히, 종래의 연결장치만으로는 다면 또는 천정부를 갖는 콘크리트 구조물을 제작할 수 없었다.Second, the conventional formwork for concrete has a problem in that it is very difficult to produce a multi-walled wall, that is, a connected wall, so that only a single-sided concrete wall can be manufactured. In particular, it was not possible to manufacture a concrete structure having a multi-faceted or ceiling with a conventional connection device alone.
셋째, 종래의 콘크리트용 거푸집은 수평조절기능이 없어서 수평상태가 아닌 경사진 바닥면에 설치될 경우에 완성된 콘크리트용 거푸집은 바닥면을 따라 경사지게 형성된다. 이와 같이, 콘크리트용 거푸집이 수평도를 유지하지 못하게 되면, 거푸집 자체의 강도가 취약해짐은 물론, 완성된 콘크리트 구조물의 수직도가 떨어져 정밀한 콘크리트 구조물을 시공할 수 없게 된다. 아울러, 콘크리트 구조물 자체의 안정화에 커다란 지장을 초래하게 되고, 완성된 콘크리트 구조물의 주변공사도 제대로 이루어질 수 없게 된다.Third, the conventional formwork for concrete is inclined along the bottom surface when the formwork is completed when it is installed on the inclined floor surface rather than the horizontal state. As such, when the formwork for concrete does not maintain a horizontal level, the strength of the formwork itself becomes weak, as well as the verticality of the finished concrete structure is not able to construct a precise concrete structure. In addition, it will cause a great obstacle to the stabilization of the concrete structure itself, the periphery of the finished concrete structure also can not be made properly.
넷째, 종래의 거푸집은 해체하고자 할 때, 거치대 하부에 바닥지지대가 끼워져 있는 상태이므로 거치대를 제거한 다음 바닥지지대를 해체시킬 수 밖에 없다. 그러나, 콘크리트가 양생되는 과정에서 거치대가 바깥쪽으로 강한 힘을 받고 있는 상태이고 바닥지지대는 바닥에 고정된 상태이므로 거치대와 바닥지지대 사이에는 강한 밀착력이 발생되어 거치대의 철거작업이 매우 힘든 문제가 있다.Fourth, when the conventional formwork is to be dismantled, the bottom support is inserted into the bottom of the cradle, so the bottom support can only be dismantled after removing the cradle. However, in the process of curing the concrete, the cradle is receiving a strong force to the outside and the floor support is fixed to the floor, so strong adhesion between the cradle and the floor support is a problem that the removal of the cradle is very difficult.

도 4 및 도 5에 도시된 바와 같이, 상기 제1조임수단은 수직지지대(130)의 외측면에 형성된 끼움공(131)과, 상기 끼움공(131)에 끼워져 결합되며 끼움공(131)측으로 확관되도록 중앙에 단턱부(136a)가 형성된 가이드관(136)과, 상기 가이드관(136)을 통과하여 밀착부재(140)의 전면에 고정되는 관통볼트(132)와, 상기 관통볼트(132)에 체결되어 가이드관(136)의 단턱부(136a)에 밀착되게 조여지는 조임너트(133)로 구성된다.4 and 5, the first fastening means is fitted with the fitting hole 131 formed on the outer surface of the vertical support 130, the fitting hole 131 is coupled to the fitting hole 131 side A guide tube 136 having a stepped portion 136a formed at the center thereof so as to be expanded, a through bolt 132 fixed to the front surface of the contact member 140 by passing through the guide tube 136, and the through bolt 132. The fastening nut 133 is fastened to the stepped portion 136a of the guide tube 136 to be tightly coupled thereto.
그리고, 상기 밀착부재(140)의 전면에는 상기 제1조임수단의 관통볼트(132)를 고정시키기 위한 별도의 볼트(141)가 체결되어 있으며, 상기 관통볼트(132)의 나사부 단부에는 상기 볼트(141)에 대응되는 나사공(132a)이 형성된다.In addition, a separate bolt 141 for fastening the through bolt 132 of the first tightening means is fastened to the front surface of the contact member 140, and the bolt (end) is formed at the threaded end of the through bolt 132. A screw hole 132a corresponding to 141 is formed.
상기 관통볼트(132)는 가이드관(136)에 의해 수직지지대(130)의 끼움공(131) 내부에서 안정적으로 볼트(141)와 결합되며, 상기 조임너트(133) 역시 안정된 상태로 밀착이 이루어지게 된다. The through bolt 132 is stably coupled to the bolt 141 in the fitting hole 131 of the vertical support 130 by the guide tube 136, the tightening nut 133 is also in close contact with a stable state You lose.
또한, 상기 거푸집 패널(120)의 내측에는 밀착부재(140)과 단차가 발생되지 않도록 안착홈(121)과 요홈(122)이 형성되며, 상기 밀착부재(140)에는 거푸집패널(120)의 요홈(121)에 대응되는 결합돌기(140a)가 형성된다.In addition, a seating groove 121 and a recess 122 are formed in the inner side of the formwork panel 120 so that a step and an adhesion member 140 are not generated, and the recessed portion of the formwork panel 120 is formed in the contacting member 140. Coupling protrusion 140a corresponding to 121 is formed.
한편, 상기 거푸집패널(120)에는 패널의 양단부를 감싸 상기 안착홈(121)과 요홈(122)들을 보호하기 위한 보호대(125)가 더 구비될 수 있다. 상기 보호대(125)는 충분한 강도를 유지할 수 있도록 스틸로 제작되는 것이 바람직하다.On the other hand, the formwork panel 120 may be further provided with a guard 125 to protect the seating groove 121 and the groove 122 to surround both ends of the panel. The guard 125 is preferably made of steel so as to maintain sufficient strength.
그리고, 미설명부호(142)는 타설된 콘크리트가 거푸집 패널(120)의 외측으로 유출되지 않도록 거푸집패널(120)과 밀착부재(140) 사이를 긴밀하게 유지시켜 주는 실링부재이다.In addition, the reference numeral 142 is a sealing member that closely maintains between the formwork panel 120 and the contact member 140 so that the poured concrete does not flow out of the formwork panel 120.
따라서, 상기 밀착부재(140)의 볼트(141)가 관통볼트(132)의 나사공(132a)에 체결되도록 한 상태에서 상기 조임너트(133)가 수직지지대(130)의 내측면에 밀착될 때까지 관통볼트(132)에 체결이 이루어시공 바닥면 수직지지대(130)와 밀착부재(140)가 거푸집 패널(120)의 외측면과 내측면에 밀착되면서 거푸집 패널(120)들은 견고하게 연결된다. 상기와 같이 수직지지대(130)가 모두 설치되면 수평지지대(150)가 간격유지수단(160)을 통해 상기 수직지지대(130)의 외측면에 밀착지지된다.Therefore, when the fastening nut 133 is in close contact with the inner surface of the vertical support 130 in a state that the bolt 141 of the close contact member 140 is fastened to the screw hole 132a of the through bolt 132. Fastening is made to the through bolt 132 to the construction bottom vertical support 130 and the contact member 140 is in close contact with the outer surface and the inner surface of the formwork panel 120, the formwork panel 120 is firmly connected. When all the vertical support 130 is installed as described above, the horizontal support 150 is in close contact with the outer surface of the vertical support 130 through the gap maintaining means 160.
도 6에 도시된 바와 같이, 상기 간격유지수단(160)은 바닥지지대들(111,112)의 외부로 양단이 돌출되도록 마주하는 거푸집 패널(120)들을 수평으로 관통하는 연결볼트(161)와, 상기 연결볼트(161)의 양단에 체결되어 수평지지대(150)의 전면에 밀착되게 조여지는 조임너트(162)로 구성된다. 이 경우, 상기 수평지지대(150)는 소정의 연결구(170)를 통해 일정간격을 유지하는 상부수평지지대(151)와 하부수평지지대(152)로 이루어지도록 하는 것이 바람직하다. 이는 상기 연결볼트(161)의 양단이 상부수평지지대(151)와 하부수평지지대(152) 사이로 돌출되도록 하여 상기 조임너트(162)가 상부수평지지대(151)와 하부수평지지대(152)에 동시 밀착되어 조임동작을 수행할 수 있도록 하기 위함이다.As shown in FIG. 6, the gap maintaining means 160 includes a connection bolt 161 horizontally passing through the formwork panel 120 facing each other so that both ends protrude out of the floor supports 111 and 112, and the connection. The fastening nut 162 is fastened to both ends of the bolt 161 and tightened to be in close contact with the front surface of the horizontal support 150. In this case, the horizontal support 150 is preferably made of an upper horizontal support 151 and a lower horizontal support 152 to maintain a predetermined interval through a predetermined connector 170. This causes both ends of the connecting bolt 161 to protrude between the upper horizontal support 151 and the lower horizontal support 152 so that the tightening nut 162 is in close contact with the upper horizontal support 151 and the lower horizontal support 152 at the same time. This is to allow the tightening operation to be performed.
한편, 상기 연결볼트(161)는 거푸집 패널(120)의 내측면과 인접한 지점에서의 외경을 축소시키는 한 쌍의 오목부(161a)를 더 구비할 수도 있다. 상기 오목부(161a)는 도 6b에 도시된 바와 같이, 거푸집이 철거될 때 콘크리트 구조물 외측으로 돌출된 연결볼트(161)의 양단부를 제거하기 위한 절단지점이 된다. 이 경우, 상기 한 쌍의 오목부(161a)에는 거푸집 패널(120)의 내측면에 간섭됨으로써 연결볼트(161)의 위치이동을 제한하는 와셔(180)가 결합된다. 따라서, 상기 오목부(161a)는 항상 거푸집 패널(120)의 내측면에 밀착된 상태를 유지하게 된다.On the other hand, the connection bolt 161 may further include a pair of recesses (161a) for reducing the outer diameter at the point adjacent to the inner surface of the formwork panel 120. As shown in FIG. 6B, the recess 161a is a cutting point for removing both ends of the connecting bolt 161 protruding outside the concrete structure when the formwork is demolished. In this case, the pair of recesses 161a are coupled to the washers 180 to limit the movement of the connection bolt 161 by interfering with the inner surface of the formwork panel 120. Therefore, the concave portion 161a is always maintained in close contact with the inner surface of the formwork panel 120.
한편, 도 7에 도시된 바와 같이 상기 와셔(180)는 오목부(161a)에 끼워질 수 있도록 상기 오목부(161a)의 외경보다는 크고 연결볼트(161)의 외경보다는 작게 형성된 끼움공(181)과, 상기 끼움공(181)과 연결된 개방슬릿(182)과, 상기 끼움공(181)에 끼워진 오목부(161a)의 하부를 탄성지지하도록 상기 개방슬릿(182)에 인접한 부위가 끼움공(181)측으로부터 와셔(180)의 외측으로 부분절개되어 이루어진 탄성지지부(183)로 구성된다.Meanwhile, as shown in FIG. 7, the washer 180 has a fitting hole 181 formed larger than an outer diameter of the concave portion 161 a and smaller than an outer diameter of the connecting bolt 161 so as to fit into the concave portion 161 a. And an opening slit 182 connected to the fitting hole 181 and a portion adjacent to the opening slit 182 to elastically support a lower portion of the recess 161a fitted to the fitting hole 181. It is composed of an elastic support portion 183 made by partially cutting out of the washer 180 from the side.
상기 와셔(180)는 상기 개방슬릿(182)을 통해 오목부(161a)에 끼워지게 되며, 상기 탄성지지부(183)는 오목부(161a)가 개방슬릿(182)으로 인입될 때에는 오목부(161a)에 밀려 개방슬릿(182)측으로 밀착되고 오목부(161a)가 끼움공(181)에 완전하게 끼워진 상태에서는 자체 탄성력에 의해 원래 위치로 복귀하면서 오목부(161a)의 하부를 지지하게 된다. 따라서, 상기 와셔(180)는 오목부(161a)로부터의 이탈됨이 방지된다.The washer 180 is fitted into the recess 161a through the open slit 182, and the elastic support 183 is recessed 161a when the recess 161a is drawn into the open slit 182. In the state of being pushed in close contact with the open slit 182 side and the recess 161a is completely fitted in the fitting hole 181, the lower part of the recess 161a is supported while returning to its original position by its elastic force. Thus, the washer 180 is prevented from being separated from the recess 161a.
한편, 도 8 및 도 9에 도시된 바와 같이, 상기 조임너트(162)는 합치가 가능하도록 힌지결합된 한 쌍의 분할너트(162a,162b)와, 상기 분할너트(162a,162b)가 합치된 상태를 유지시킬 수 있도록 결속시키는 록킹부재로 구성될 수도 있다. 상기 록킹부재는 각 분할너트(162a,162b)의 합치부에 돌출 형성된 결속공(162c,162d)과, 각 분할너트(162a,162b)의 결속공(162c,162d)에 차례로 끼워지는 단일의 연결핀(162e)과, 상기 연결핀(162e)의 단부에 매달려 결속공(162c,162d)의 단부에 걸림으로써 연결핀(162e)이 결속공(162c) 내부에서 항상 일정한 깊이로 끼움상태를 유지할 수 있게 하는 걸림고리(162f)로 구성된다.Meanwhile, as shown in FIGS. 8 and 9, the tightening nut 162 includes a pair of split nuts 162a and 162b hinged to be matched with the split nuts 162a and 162b. It may be composed of a locking member for binding to maintain the state. The locking member is a single connection that is inserted into the binding holes (162c, 162d) protruding at the mating portion of each of the split nuts (162a, 162b) and the binding holes (162c, 162d) of each of the split nuts (162a, 162b) in turn. By connecting the pins 162e and the ends of the binding holes 162c and 162d by hanging the ends of the connecting pins 162e, the connection pins 162e can always be fitted at a constant depth inside the binding holes 162c. It consists of a catch ring 162f.
이 경우, 결속공(162c)의 내부에는 단턱(162g)가 형성되고 상기 연결핀(162e)에는 상기 단턱(162g)에 걸리는 돌출부(162h)를 형성된다. 따라서, 상기 연결핀(162e)이 결속공(162c)에 삽입된 상태에서는 상기 단턱(162g)에 돌출부(162h)가 걸려 결속공(162c)으로부터 이탈되지 않는다.In this case, a stepped portion 162g is formed inside the binding hole 162c, and a protrusion 162h that is caught by the stepped portion 162g is formed on the connection pin 162e. Therefore, in the state in which the connecting pin 162e is inserted into the binding hole 162c, the protrusion 162h is caught by the step 162g so as not to be separated from the binding hole 162c.
작업자는 분할너트(162a,162b)를 수평지지대(150)의 외측면에 근접하게 위치시킨 상태에서 연결볼트(161)에 직접 체결할 수 있게 되므로 수평지지대(130)의 외측면에 밀착될 때까지 조임너트(162)를 다수 회 회전시키지 않고도 빠르고 간편하게 조임작업을 수행할 수 있게 된다.The operator can be directly coupled to the connecting bolt 161 in a state in which the split nut (162a, 162b) is located close to the outer surface of the horizontal support 150 until it is in close contact with the outer surface of the horizontal support 130 Fastening operation can be performed quickly and easily without rotating the tightening nut 162 a plurality of times.

이하 첨부된 도면을 참조하여 천정면을 포함하는 다면벽체의 콘크리트 구조물을 시공할 경우, 본 발명에 따른 콘크리트용 거푸집을 설치 및 사용하는 과정을 살펴본다.Hereinafter, with reference to the accompanying drawings, when constructing a concrete structure of a multi-walled wall including a ceiling surface, looks at the process of installing and using the formwork for concrete according to the present invention.
먼저 콘크리트 구조물을 이루는 다면벽체를 형성할 수 있는 거푸집이 다음과 같이 설치된다.First, formwork that can form a multi-faceted wall forming a concrete structure is installed as follows.
내측바닥지지대(111)들과 외측바닥지지대(112)들이 내향 코너부들만을 갖도록 바닥에 수평상태로 고정되면, 각 바닥지지대(111,112)의 상부에 거치대(113)가 설치되며, 이 거치대(113) 상부에 수직지지대(130)가 설치된 다음 수직지지대(130)와 마주보도록 거푸집 패널(120)과 밀착부재(140)가 차례로 배치된다. 상기 외측바닥지지재(112)들에 설치되는 거푸집 패널(120)들은 내측바닥지지대(111)들에 설치되는 거푸집 패널(120)들보다 시공될 천정면의 두께만큼 길게 형성된다. 이때, 거푸집 패널(120)의 양측단에 형성된 요홈에 밀착부재(140)의 양측단에 형성된 결합돌기가 결합되면서, 상기 거푸집 패널(120)과 밀착부재(140)는 동일면을 이룬 상태로 밀착부재(140)와 수직지지대(130)가 거푸집의 양측면에 각각 견고하게 밀착된다. 따라서, 시공될 콘크리트 구조물 벽면에 자국이 남지 않는다.When the inner bottom support 111 and the outer bottom support 112 are fixed horizontally to the floor so as to have only inward corner portions, a cradle 113 is installed on the top of each floor support 111 and 112, and the cradle 113. After the vertical support 130 is installed on the upper side, the formwork panel 120 and the contact member 140 are sequentially disposed to face the vertical support 130. The formwork panels 120 installed on the outer bottom support members 112 are formed to have a thickness longer than that of the formwork panels 120 installed on the inner bottom support members 111. At this time, while the coupling protrusions formed at both ends of the contact member 140 are coupled to grooves formed at both ends of the formwork panel 120, the formwork panel 120 and the contact member 140 are in close contact with each other. 140 and the vertical support 130 are firmly in close contact with both sides of the formwork, respectively. Thus, no marks remain on the wall of the concrete structure to be constructed.
한편, 상기 내측바닥지지대(111)와 외측바닥지지대(112)가 이루는 각각의 코너부에 양단이 각각 상기 내측바닥지지대(111,111)와 외측바닥지지대(112,112)에 접하도록 코너바닥지지블럭(114)이 끼워진다. 이 코너바닥지지블럭(114)은 콘크리트의 양생이 완료된 이후 바닥지지대들(111,112)의 철거 이전에 상기 바닥지지대들(111,112)로부터 인출시켜 철거 유격을 제공함으로써 양생된 콘크리트에 밀착된 상태인 바닥지지대들(111,112)의 철거가 용이하게 이루어지도록 돕는다.On the other hand, the corner bottom support block 114 so that both ends of the inner bottom support 111 and the outer bottom support 112 are in contact with the inner bottom support (111, 111) and the outer bottom support (112, 112), respectively. Is fitted. The corner floor support block 114 is pulled out from the floor supports 111 and 112 after the completion of curing of the concrete before the dismantling of the floor supports 111 and 112 to provide a dismantling clearance, the floor support in close contact with the cured concrete Help to facilitate the removal of the fields (111, 112).
상기와 같이 수직지지대(130)가 모두 설치되면 수직지지대(130)의 외측면에 제1지지브라켓(190)이 조립되고, 이 제1지지브라켓(190)에 하부가 지지된 상태로 수평지지대(150)가 간격유지수단(160)을 통해 수직지지대(130)의 외측면에 밀착 설치된다. 이때 상기 수평지지대(150)는 소정의 연결구(170)를 통해 상하로 일정간격을 유지한 상태로 설치되며, 이 사이로 간격유지수단(160)의 연결볼트(161)가 바닥지지대들(111,112)의 외부로 양단이 돌출되도록 마주하는 거푸집 패널(120)들을 수평으로 관통설치된다. 연결볼트(161)가 설치되면 마주하는 거푸집 패널(120)들의 내측으로 와셔(180)가 끼워진다. 상기 와셔(180)는 개방슬릿(182)을 통해 연결볼트(161)의 오목부(161a)에 끼워지게 되며, 일단 오목부(161a)가 끼워진 상태에서는 탄성지지부(183)가 오목부(161a)의 하단을 탄성지지하게 되므로 오목부(161a)로부터의 이탈이 확실하게 방지된다.When all the vertical support 130 is installed as described above, the first support bracket 190 is assembled on the outer surface of the vertical support 130, and the horizontal support (the lower support is supported by the first support bracket 190). 150 is installed in close contact with the outer surface of the vertical support 130 through the gap maintaining means (160). At this time, the horizontal support 150 is installed in a state maintaining a constant interval up and down through a predetermined connector 170, between the connecting bolt 161 of the interval maintaining means 160 of the bottom support (111, 112) Formwork panels 120 facing each other so that both ends protrude outwards are horizontally installed. When the connection bolt 161 is installed, the washer 180 is fitted into the mold panels 120 facing each other. The washer 180 is fitted into the recess 161a of the connecting bolt 161 through the open slit 182, and the elastic support 183 is the recess 161a once the recess 161a is fitted. Since the bottom of the elastic member is elastically supported, separation from the recess 161a is reliably prevented.
이렇게 하면, 연결볼트(161)의 오목부(161a)가 항상 거푸집 패널(120)들의 내측면에 정확하게 위치됨과 동시에 와셔(180)가 거푸집 패널(120)의 내측면에 지지되면서 연결볼트(161)의 유동이 제한된다. 그리고 간격유지수단(160)의 조임너트(162)가 연결볼트(161)의 단부에 체결되어 수평지지대(150)를 수직지지대(130)에 긴밀히 밀착시킨다.In this way, the concave portion 161a of the connecting bolt 161 is always accurately positioned on the inner side of the formwork panel 120 and the washer 180 is supported on the inner side of the formwork panel 120 while the connecting bolt 161 is provided. The flow of is limited. And the tightening nut 162 of the gap maintaining means 160 is fastened to the end of the connection bolt 161 to closely contact the horizontal support 150 to the vertical support 130.
한편, 상기 조임너트(162)는 한 쌍의 분할너트(162a,162b)로 되어 있기 때문에 분할너트(162a,162b)를 수평지지대(150)의 외측면에 근접하게 위치된 상태에서 연결볼트(161)에 체결될 수 있다. 따라서, 수평지지대(150)의 외측면에 밀착될 때까지 조임너트를 다수 회 회전시키지 않고 빠르고 간편하게 체결작업 및 해체작업을 수행할 수 있게 된다.On the other hand, since the tightening nut 162 is a pair of split nuts (162a, 162b), the connection bolt 161 in the state in which the split nuts (162a, 162b) is located close to the outer surface of the horizontal support 150 Can be fastened to Therefore, the fastening and disassembly operations can be performed quickly and simply without rotating the tightening nut a plurality of times until it is in close contact with the outer surface of the horizontal support 150.
아울러, 도 9a에 도시된 바와 같이, 각 분할너트(162a,162b)의 합치부에 돌출 형성된 결속공(162c,162d)에 연결핀(162e)이 삽입된 상태에서 록킹이 이루어지며, 걸림고리(162f)에 손가락을 걸고 가볍게 잡아당기면 도 9b와 같이 연결핀이 결속공(162c,162d)의 내부에서 바깥쪽으로 이동하면서 록킹상태가 해제된다. 이때, 연결핀(162e)은 돌출부(162h)가 결속공(162c)의 단턱(162g)에 걸린 상태가 되므로 결속공(162c)으로부터 이탈되지 않게 되므로 작업도중 연결핀(162e)이 분실될 염려가 없다.In addition, as shown in Figure 9a, the locking is made in the state in which the connecting pin 162e is inserted into the binding holes (162c, 162d) protruding in the mating portion of each of the split nuts (162a, 162b), the locking ring ( 162f) when the finger is pulled lightly, as shown in FIG. 9B, the locking pin is released while the connecting pin moves outward from the inside of the binding holes 162c and 162d. At this time, since the connecting pin 162e is in a state where the protrusion 162h is caught in the stepped portion 162g of the binding hole 162c, the connection pin 162e may not be separated from the binding hole 162c. none.
이와 같은 방법으로 콘크리트 구조물을 이루는 각 다면벽체를 형성할 수 있는 거푸집들이 완성되면, 각 거푸집들의 코너부가 연결된다. 상기 거푸집들의 코너부는 코너부 지지대(210)와 코너부 밀착부재(220)와 제2조임수단(230)을 통해 연결된다.In this way, when the formwork that can form each of the multi-faceted wall forming the concrete structure is completed, the corner portion of each formwork is connected. The corners of the formwork are connected through the corner support 210, the corner contact member 220, and the second fastening means 230.
즉, 외측바닥지지대(112)에 설치된 코너부의 거푸집 패널(120)들은 나사단부가 코너부 밀착부재(220)의 모서리부에 밀착되도록 코너부 지지대(210)의 외측면에 관통볼트(231)가 관통결합된 상태에서 상기 코너부 밀착부재(220)의 모서리부를 통해 볼트가 상기 관통볼트(231)의 나사단부에 형성된 나사홈부(232)에 체결되고, 관통볼트(231)에 끼워진 조임너트(234)가 코너부 지지대(210)의 내측면에 밀착될 때까지 조여짐으로써 견고하게 연결된다.That is, the formwork panel 120 of the corner portion installed in the outer bottom support 112 has a through bolt 231 on the outer surface of the corner support 210 so that the screw end is in close contact with the corner of the corner contact member 220. A bolt is fastened to a screw groove 232 formed at a screw end of the through bolt 231 through a corner portion of the corner contact member 220 in a through coupling state, and a tightening nut 234 inserted into the through bolt 231. ) Is firmly connected by being tightened until it is in close contact with the inner surface of the corner support 210.
그리고, 상기 내측바닥지지대(111)에 설치된 거푸집 패널(120)들은 나사단부가 코너부 지지대(210)의 모서리부에 밀착되도록 코너부 밀착부재(220)의 외측면에 관통볼트(235)가 관통결합된 상태에서 상기 코너부 지지대(210)의 모서리부를 통해 볼트(236)가 상기 관통볼트(235)의 나사단부에 형성된 나사홈부(236)에 체결되고, 관통볼트(235)에 끼워진 조임너트(236)가 코너부 밀착부재(220)의 내측면에 밀착될 때까지 조여짐으로써 견고하게 연결된다.In addition, the through-plate 235 penetrates the outer surface of the corner contact member 220 so that the screw panel 120 is installed on the inner bottom support 111 so that the screw end is in close contact with the corner of the corner support 210. In the coupled state, the bolt 236 is fastened to the screw groove 236 formed at the screw end of the through bolt 235 through the corner portion of the corner support 210, and a tightening nut fitted to the through bolt 235 ( 236 is firmly connected by being tightened until it is in close contact with the inner side of the corner contact member 220.
이때, 상기 관통볼트(235)의 나사단부 양측에 모따기부(235a)가 가공될 경우, 관통볼트(235)의 나사단부가 코너부 밀착부재(220)의 모서리부에 긴밀하게 밀착될 수 있게 되므로 관통볼트(235)와 볼트(236)가 안정된 상태로 결합될 수 있다.At this time, when the chamfered portion 235a is processed on both sides of the threaded end of the through-bolt 235, the screwed end of the through-bolt 235 can be in close contact with the corner portion of the corner contact member 220 The through bolt 235 and the bolt 236 may be coupled in a stable state.
이와 같이 거푸집 패널(120)의 코너부가 모두 연결되면, 결속수단(240)을 통해 상기 코너부 지지대(210)의 양측으로 마주하는 한 쌍의 수평지지대(150)가 일체로 연결된다.When the corners of the formwork panel 120 are all connected as described above, a pair of horizontal supports 150 facing both sides of the corner support 210 through the binding means 240 are integrally connected.
즉, 각 수평지지대(150)의 단부가 상기 결속수단(240)의 끼움부(241)에 끼워시공 바닥면 상기 끼움부(241)의 상단에 형성된 관통공(242)에 체결된 조임볼트(243)가 오른쪽으로 회전되면서 조임볼트(243) 단부에 미리 조립된 밀착편(244)의 중앙부를 가압하여 수평지지대(150)의 상부에 밀착시킨다. 이때, 상기 밀착편(244)은 수평지지대(150)의 진입방향에 대하여 직각방향의 양측단이 수평지지대(150)의 외측면에 밀착되도록 중앙부가 수평지지대(150) 외측으로 이격되는 방향으로 만곡되어 있으므로 수평지지대(150)를 매우 견고하게 결속시켜 줄 수 있다. 따라서, 거푸집 사이로 콘크리트가 타설되는 과정에서 발생되는 콘크리트 압력에 의해 거푸집이 손상되지 않는다.That is, the end of each horizontal support 150 is fastened to the through-hole 242 formed in the upper end of the fitting portion 241 is fitted to the fitting portion 241 of the binding means 240 fastening bolts 243 ) Is rotated to the right to press the central portion of the contact piece 244 pre-assembled to the end of the tightening bolt 243 to be in close contact with the upper portion of the horizontal support 150. At this time, the close contact piece 244 is curved in a direction in which the center portion is spaced outward of the horizontal support 150 so that both ends of the right angle direction in close contact with the entry direction of the horizontal support 150 is in close contact with the outer surface of the horizontal support 150. Since it is possible to bind the horizontal support 150 very firmly. Therefore, the formwork is not damaged by the concrete pressure generated in the process of pouring concrete between the formwork.
이와 같이, 코너부 지지대(210)의 양측으로 마주하는 한 쌍의 수평지지대(150)가 견고하게 결속되면, 상기 내측바닥지지대(111)들의 거푸집 패널(120)들 상단에 상부 거푸집 패널(300)이 설치된다. 상기 상부 거푸집 패널(300)은 마주하는 거푸집 패널(120b,120b)의 상단과 코너부를 형성하도록 수평으로 설치되며, 상기 코너부는 상술한 코너부 지지대(210)와 코너부 밀착부재(220) 및 제2조임수단(230)을 통해 연결된다.As such, when a pair of horizontal supports 150 facing both sides of the corner support 210 are firmly bound, the upper formwork panel 300 is formed on top of the formwork panels 120 of the inner bottom support 111. This is installed. The upper formwork panel 300 is horizontally installed to form upper and corner portions of the facing formwork panels 120b and 120b, and the corner portion is formed with the corner support 210 and the corner contact members 220 and the above-described corner support.

This is because the second support bracket 420 is in a state where the uppermost horizontal support 150a is receiving a large load from the lower supports 310 of the upper formwork panel 300 unlike the first support bracket 190. This is to allow easy separation from the vertical support 130 by horizontally moving outward without applying force.
상기와 같은 과정을 거치면 천정면을 갖는 콘크리트 구조물의 시공을 위한 거푸집이 완성된다. 거푸집이 완성되면 거푸집 내부로 콘크리트를 타설되고 양생 및 건조과정을 거친 후에 설치된 거푸집은 철거된다.After the above process, the formwork for the construction of the concrete structure having a ceiling surface is completed. Once the formwork is completed, the formwork is poured into the formwork and the formwork installed after curing and drying is removed.
거푸집의 철거과정은 상기한 설치과정의 역순으로 이루어지는데, 연결볼트(161)는 중간부분이 콘크리트와 함께 일체화된 상태이므로 콘크리트 외부로 돌출된 부분만 제거된다. 작업자는 거푸집 패널(120)들을 철거하기 이전에 상기 연결볼트(161)의 돌출부를 적절한 공구를 이용하여 잡아 비틀어 제거한다. 상기 연결볼트(161)의 돌출부를 잡아 비틀게 되면 오목부(161a)가 인장되면서 외경이 급격하게 작아져 쉽게 절단될 수 있는 것이다.The dismantling process of the formwork is made in the reverse order of the installation process, the connection bolt 161 is removed because only the protruding portion outside the concrete because the middle portion is integrated with the concrete. The operator grasps and removes the protrusion of the connecting bolt 161 by using an appropriate tool before removing the formwork panels 120. If the twisting of the protrusion of the connecting bolt 161, the concave portion (161a) is tensioned and the outer diameter is sharply reduced so that it can be easily cut.
마지막으로 철거되는 바닥지지대들(111,112)은 코너바닥지지블럭(114)을 빼낸 다음 철거된다. 코너바닥지지블럭(114)은 콘크리트가 양생되는 과정에서 상기 바닥지지대들(111,112)로 인가되는 압력을 흡수하는 역할을 한다. 만일, 코너바닥지지블럭(114) 대신 코너부의 바닥지지대들(111,111)(112,112)이 서로 밀착된 상태로 배치될 경우, 콘크리트가 양생되는 과정에서 바닥지지대들(111,111)(112,112)간에 큰 압력이 작용하게 되므로 결국 인력으로는 바닥지지대들(111,111)(112,112)을 철거할 수 없게 된다. 따라서, 상기 코너바닥지지블럭(114)에 의해 바닥지지대들(111,111)(112,112)의 철거가 매우 용이하게 이루어지게 된다.Finally, the floor supports 111 and 112 to be dismantled are removed after removing the corner floor support block 114. The corner floor support block 114 serves to absorb the pressure applied to the floor supports 111 and 112 in the process of curing concrete. If the floor supports 111, 111, 112, 112 of the corner portions are arranged in close contact with each other instead of the corner floor support block 114, a large pressure is applied between the floor supports 111, 111, 112, 112 during the curing of concrete. As a result, it is impossible to remove the floor supports 111, 111, 112, and 112 with manpower. Therefore, the bottom support blocks 111, 111, 112, 112 are removed by the corner floor support block 114 very easily.
본 발명을 구성하는 구성부품들은 철거된 이후 거푸집 제작시 모두 재이용이 가능하므로 거푸집 제작비 절감이나 재활용 측면에서 매우 유리하다.Since the components constituting the present invention can be reused at the time of formwork after being demolished, it is very advantageous in terms of form reduction or recycling.
도 24 내지 도 26에 도시된 바와 같이, 본 발명을 구성하는 제1조임수단의 다른 실시예로서, 제1조임수단은 수직지지대(130)의 외측면에 형성된 끼움공(510)과, 상기 끼움공(510)의 내측에 고정되어 상기 끼움공(510)의 내측 전면으로 수직의 지지면(221)을 형성시키는 지지부재(520)와, 상기 지지부재(520)를 통과하여 밀착부재(140)의 전면에 체결되는 관통핀(530)과, 상기 관통핀(530)의 단부에 힌지결합되며 회동상태에 따라 지지부재(520)와의 밀착력을 달리하는 조임부재(540)로 구성될 수 있다.As shown in Figures 24 to 26, as another embodiment of the first tightening means constituting the present invention, the first tightening means is a fitting hole 510 formed on the outer surface of the vertical support 130, and the fitting The support member 520 is fixed to the inside of the ball 510 to form a vertical support surface 221 toward the inner front of the fitting hole 510, and the contact member 140 passes through the support member 520. The through pin 530 is fastened to the front of the, and the hinge pin is coupled to the end of the through pin 530 may be composed of a fastening member 540 to vary the adhesion with the support member 520 according to the rotational state.
상기 끼움공(510)의 내측에 고정된 지지부재(520)는 강도적으로 우수한 스틸 플레이트가 적당하며 용접을 통해 수직지지대(130)에 미리 부착되어 있다. 상기 지지부재(520)의 중앙에는 관통핀(530)이 통과할 수 있도록 관통홀(522)이 형성되어 있다. 이 관통홀(522)은 관통핀(530)의 외경보다 큰 직경을 갖도록 형성되어 있어서 관통핀(530)이 자유롭게 유동될 수 있다.The support member 520 fixed to the inside of the fitting hole 510 is preferably a steel plate excellent in strength and is attached to the vertical support 130 through welding in advance. A through hole 522 is formed at the center of the support member 520 to allow the through pin 530 to pass therethrough. The through hole 522 is formed to have a diameter larger than the outer diameter of the through pin 530 so that the through pin 530 can freely flow.
상기 밀착부재(140)의 전면에는 상기 관통핀(530)을 체결시키기 위한 볼트(141)가 체결된다. 그리고 상기 관통핀(530)의 단부에는 상기 볼트(141)에 대응되는 나사공(531)이 형성된다. 따라서, 상기 관통핀(530)은 지지부재(520)에 의해 끼움공(510) 내부에서 볼트(141)와 안정적으로 결합된다.A bolt 141 for fastening the through pin 530 is fastened to the front surface of the contact member 140. A threaded hole 531 corresponding to the bolt 141 is formed at the end of the through pin 530. Therefore, the through pin 530 is stably coupled with the bolt 141 in the fitting hole 510 by the support member 520.
한편, 상기 밀착부재(140)의 중앙에는 돌부(550)가 형성되고 상기 나사공(531)이 형성된 관통핀(530)의 단부에는 상기 돌부(550)와 대응되는 홈부(532)가 형성될 수 있다. 이 경우, 상기 볼트(541)는 돌부(550)를 관통하여 밀착부재(140)의 전면에 체결된다. 따라서, 상기 관통핀(530)은 홈부(532)에 돌부(550)가 끼워진 상태에서 볼트(141)와 체결되므로, 예컨대 타설된 콘크리트를 안정화시키기 위하여 진동기(미도시)를 동작시킴으로써 발생되는 외부의 진동이나 충격에도 불구하고, 볼트(141)와의 양호한 체결력을 항상 유지할 수 있다.Meanwhile, a protrusion 550 may be formed at the center of the contact member 140, and a groove 532 corresponding to the protrusion 550 may be formed at an end of the through pin 530 having the screw hole 531. have. In this case, the bolt 541 is fastened to the front surface of the contact member 140 through the protrusion 550. Therefore, since the through pin 530 is fastened to the bolt 141 in the state where the protrusion 550 is inserted into the groove 532, the through pin 530 is externally generated by operating a vibrator (not shown), for example, to stabilize the placed concrete. In spite of vibration and shock, a good fastening force with the bolt 141 can always be maintained.
조임부재(540)는 상기 관통핀(530)의 단부에 힌지결합된 힌지부(541)와, 상기 지지부재(520)를 향해 상기 힌지부(541)로부터 연장형성된 편심접촉부(542)와, 상기 끼움공(510)을 향해 상기 힌지부(541)로부터 연장형성된 손잡이부(543)로 구성된다. 상기 편심접촉부(542)는 힌지부(541)를 중심으로 곡률이 갈수록 커지도록 만곡된 형상으로 이루어져 있다.The fastening member 540 includes a hinge portion 541 hinged to an end of the through pin 530, an eccentric contact portion 542 extending from the hinge portion 541 toward the support member 520, and the And a handle portion 543 extending from the hinge portion 541 toward the fitting hole 510. The eccentric contact portion 542 has a curved shape such that the curvature increases with respect to the hinge portion 541.
한편, 상기 조임부재(540)는 지지부재(520)에 대하여 균일하고 안정된 밀착력을 부여할 수 있도록 관통핀(530)을 사이에 두고 양측으로 배치되는 것이 바람직하다. 이 경우, 상기 조임부재(540)는 힌지핀(544)을 통해 서로 연동가능하게 연결된다.On the other hand, the fastening member 540 is preferably disposed on both sides with a through pin 530 therebetween to provide a uniform and stable adhesion to the support member 520. In this case, the fastening member 540 is connected to each other via a hinge pin (544).
따라서, 도 25에 도시된 바와 같이, 사용자가 관통핀(530)의 홈부(532)를 밀착부재(140)의 돌부(550)에 밀착시킨 상태에서 상기 밀착부재(140)의 볼트(141)를 관통핀(530)의 나사공(531)에 체결시키고, 손잡이부(543)를 이용하여 힌지핀(544)를 중심으로 편심접촉부(542)가 지지부재(520)에 밀착되도록 힌지부(541)를 회전시키면(도면상 아래방향), 도 26에 도시된 바와 같이, 수직지지대(130)와 밀착부재(140)가 거푸집 패널(560)의 양측면에 긴밀하게 밀착되면서 거푸집 패널(560)들이 견고하게 연결된다.Thus, as shown in FIG. 25, The user drills the bolt 141 of the contact member 140 into the screw hole 531 of the through pin 530 while the user closely contacts the groove 532 of the through pin 530 with the protrusion 550 of the contact member 140. When the hinge portion 541 is rotated so that the eccentric contact portion 542 is in close contact with the support member 520 around the hinge pin 544 using the handle portion 543 (downward in the drawing), As shown in Figure 26, the vertical support 130 and the close contact member 140 is in close contact with both sides of the formwork panel 560, the formwork panels 560 are firmly connected.

A plurality of through holes 562 and a protective cover 563 integrally formed with the panel body 561 to surround the outer surface of the panel body 561 in a state connected through the through hole 562 may be. . Accordingly, since the entire outer surface of the formwork panel 560 is protected by a protective cover 563 made of synthetic resin or steel manufactured through integral molding, the panel body 561 is extended in strength and, of course, It is easy to manufacture and can be recycled even after dismantling.
또한, 상기 거푸집 패널(560)의 양단에는 밀착부재(140)와 단차가 발생되지 않도록 안착홈(564)이 형성될 수도 있다.In addition, seating grooves 564 may be formed at both ends of the formwork panel 560 so that a step is not generated with the contact member 140.
그리고 실링을 유지하기 위한 수단으로서, 상기 거푸집 패널(560)에는 수직지지대(130)와의 결합을 위한 제1결합돌기(565)가 더 형성됨과 함께 상기 수직지지대(130)에는 상기 제1결합돌기(565)에 대응되는 제1요홈(570)이 형성될 수 있다. 이에 따라, 수직지지대(130)와 거푸집 패널(560) 사이에 실링력이 강화되므로 이 부분을 통해 타설된 콘크리트의 누설가능성이 매우 적어진다.And as a means for maintaining the sealing, the formwork panel 560 is further formed with a first coupling protrusion 565 for coupling with the vertical support 130 and the vertical support 130, the first coupling projection ( A first recess 570 corresponding to 565 may be formed. Accordingly, since the sealing force is reinforced between the vertical support 130 and the formwork panel 560, the possibility of leakage of concrete poured through this portion is very small.
도 29에 도시된 바와 같이, 거푸집 패널(560)의 또 다른 실시예로서, 상기 거푸집 패널(560)는 밀착부재(140)와의 결합을 위한 제2요홈(580)을 더 가질 수 있으며, 상기 밀착부재(140)에는 상기 제2요홈(580)에 대응되는 제2결합돌기(590)가 더 형성될 수도 있다. 물론 상기 거푸집 패널(560)에 제2결합돌기(590)가 형성되고 밀착부재(140)에 이에 대응되는 제2요홈(580)이 형성되어도 무방하다.As shown in FIG. 29, as another embodiment of the formwork panel 560, the formwork panel 560 may further have a second recess 580 for coupling with the contact member 140. The member 140 may further include a second coupling protrusion 590 corresponding to the second recess 580. Of course, a second coupling protrusion 590 may be formed in the formwork panel 560, and a second recess 580 corresponding to the contact member 140 may be formed.
이 경우, 거푸집 패널(560)과 밀착부재(140)와의 실링력을 강화시킬 수 있을 뿐만 아니라, 거푸집 패널(560)이 항상 정확한 위치에서 밀착부재(140)와 결합되므로 조립성이 향상된다.In this case, not only can the sealing force between the formwork panel 560 and the contact member 140 be strengthened, but also the formability is improved because the formwork panel 560 is always combined with the contact member 140 at the correct position.
미설명부호(142)는 타설된 콘크리트가 거푸집 패널(560)의 외측으로 유출되지 않도록 거푸집 패널(560)과 밀착부재(140)의 사이를 긴밀하게 유지시켜 주는 실링부재이다. Unexplained reference numeral 142 is a sealing member that closely maintains between the formwork panel 560 and the contact member 140 so that the poured concrete does not flow out of the formwork panel 560.

The connecting pin 650 for connecting is fixed.
상기와 같이 구성된 본 발명의 콘크리트용 거푸집(100)을 통해 거푸집(100)의 수평상태가 조절되는 과정을 살펴본다.Look at the process of adjusting the horizontal state of the formwork 100 through the formwork for concrete 100 of the present invention configured as described above.
먼저, 도 33에 도시된 바와 같이, 거푸집(100)의 경사진 지면상에 설치되어 거치대(110)가 일측으로 기울어진 경우, 작업자는 거치대(110)가 수평이 될 때까지 낮은 쪽에 있는 높낮이조절부재(630)의 승강부재(633)를 일방향(승강부재(633)가 상승되는 방향)으로 회전시키면 도 34에 도시된 바와 같이, 거푸집(100)의 수평상태를 용이하고 신속하게 조절할 수 있게 된다.First, as shown in Figure 33, when installed on the inclined surface of the formwork 100, the cradle 110 is inclined to one side, the operator adjusts the height in the lower side until the cradle 110 is horizontal When the elevating member 633 of the member 630 is rotated in one direction (the direction in which the elevating member 633 is raised), as shown in FIG. 34, the horizontal state of the formwork 100 can be easily and quickly adjusted. .
즉, 승강부재(633)를 일방향으로 회전시키면 승강부재(633)가 수직나사부(632)를 따라 승강하게 되는데, 승강부재(633)와 연결된 끼움부재(634)가 승강부재(633)와 함께 상승하면서 거치대(110)를 부분적으로 밀어 올리는 것이다. 이때, 끼움부재(634)는 승강부재(633)를 따라 회전하지는 않으므로 승강동작이 원활하게 이루어지고 레일부(620)와의 결합상태가 안정적으로 유지된다.That is, when the elevating member 633 is rotated in one direction, the elevating member 633 is elevated along the vertical screw portion 632, and the fitting member 634 connected with the elevating member 633 is raised together with the elevating member 633. While pushing up the cradle 110 partially. At this time, the fitting member 634 does not rotate along the elevating member 633, so the elevating operation is smoothly performed, and the engagement state with the rail unit 620 is stably maintained.
한편, 높낮이조절부재(630)의 조작에 따라 거치대(110)가 상승되면, 보조패널(640)의 슬롯홀(641)을 따라 거치대(110)와 시공바닥면 사이는 이격되나, 거치대(110)의 상승과는 별개로 보조패널(640)은 항상 시공바닥면에 하부가 밀착된 상태를 유지하고 있는 상태이므로 거푸집(100) 시공이후 타설되는 콘크리트가 거치대(110)의 하부와 시공바닥면의 이격된 공간을 통해 외부로 흘러나오지 않게 된다.On the other hand, when the cradle 110 is raised according to the operation of the height adjustment member 630, the cradle 110 and the construction bottom surface is spaced apart along the slot hole 641 of the auxiliary panel 640, cradle 110 Apart from the rise of the sub-panel 640 is always in the state that the bottom is in close contact with the construction floor, so the concrete that is poured after the construction of the mold 100 is spaced apart from the bottom of the cradle 110 and the construction floor. It does not flow out through the space.
이후, 거푸집(100)을 해체시킬 때에는 높낮이조절부재(630)의 바닥고정부(631)에 고정된 못과 같은 고정부재를 제거한 다음 승강부재(633)를 타측으로 회전시킨다. 이렇게 하면 승강부재(633)가 수직나사부(632)로 체결이 진행되면서 바닥고정부(631)가 시공바닥면으로부터 이격된다. 이 상태에서는 높낮이조절부재(630)를 거치대(110)의 레일부(620)로부터 쉽게 분리시킬 수 있다. 높낮이조절부재(630)가 레일부(620)로부터 분리되면, 작업자는 거치대(110)를 바깥쪽으로 잡아당겨 거치대(110)를 신속하고 용이하게 해체할 수 있다.Subsequently, when dismantling the formwork 100, the fixing member such as a nail fixed to the bottom fixing part 631 of the height adjusting member 630 is removed, and then the lifting member 633 is rotated to the other side. In this way, while the lifting member 633 is fastened to the vertical screw portion 632, the bottom fixing part 631 is spaced apart from the construction floor surface. In this state, the height adjusting member 630 can be easily separated from the rail portion 620 of the holder 110. When the height adjusting member 630 is separated from the rail unit 620, the operator can pull the cradle 110 to the outside to quickly and easily dismantle the cradle 110.
