본 발명은 거푸집용 간격유지구에 관한 것으로, 특히 외측 거푸집에 설치되어 콘크리트 양생후 건축물의 콘크리트 벽체에 매립된 상태로 잔류되는 간격유지구의 단부가 우수에 의해 부식되거나 녹물이 건축물 외벽으로 누출되지 않도록 개선된 구조를 갖는 거푸집용 간격유지구에 관한 것이다.The present invention relates to a gap maintaining zone for a formwork, in particular, the end of the gap maintaining zone, which is installed in the outer formwork and remains in a state buried in the concrete wall of the building after curing, prevents corrosion or rust from leaking to the exterior wall of the building. It relates to a formwork spacing for improved formwork.

건축물을 콘크리트로 타설하여 건축하는 경우에 거푸집 패널을 내외측에 일정간격을 두고 설치하여야 하는데, 양측 거푸집 패널들의 간격을 일정하게 유지하기 위하여 소위 세파타이라고 지칭되는 간격유지구로서 타이볼트나 타이바를 사용한다.When the building is constructed by pouring concrete, the formwork panels must be installed at regular intervals on the inside and outside. In order to keep the distance between the formwork panels on both sides, the tie bolt or tie bar as a so-called space maintainer called septa use.

종래의 거푸집 폼들 사이의 간격유지를 위한 타이볼트는, 국내 공개특허공보 제10-2009-0091895호(공개일자 2009년08월31일)와 국내 등록실용신안공보 제20-0402917호(2005.12.01.등록)에 개시된 거푸집용 간격유지타이볼트에서와 같이 봉형상으로 이루어지며 수나사산이 형성되어 외측거푸집의 관통공을 통해 삽입되어 콘형 체결부에 체결되는 외측고정부와, 판형상으로 일체로 형성되되 양측면에는 절단용홈이 형성되고 중앙부에는 핀결합공이 각각 형성되어 내측 거푸집의 외측면에서 고정핀이 상기 핀결합공에 끼워지도록 된 내측고정부로 구성된다.Tie bolts for maintaining the gap between conventional formwork foams are disclosed in Korean Patent Application Publication No. 10-2009-0091895 (published on August 31, 2009) and Korean Registered Utility Model Publication No. 20-0402917 (2005.12.01 .Registration) is made of rod-shaped gap retaining tie bolts as disclosed in the figure, and is formed integrally with the outer fixing part that is inserted through the through-hole of the outer die and fastened to the cone-shaped fastening part, as in the form of a rod. Recess grooves are formed on both sides, and pin coupling holes are formed at the center, respectively, and the fixing pins are fixed to the pin coupling holes on the outer surface of the inner formwork.

다른 형태의 타이볼트는 판상으로 형성되어 일측단의 양측면에 절단용홈이 형성되는 한편 중앙에는 핀결합공이 형성된 내측 고정부와 함께, 타단의 외측 고정부에는 수나사산이 형성된 볼트를 접합하여 형성하였다.The other type of tie bolt is formed in a plate shape, and cutting grooves are formed on both sides of one side, while an inner fixing portion having a pin coupling hole is formed in the center, and a bolt having a male thread formed on the outer fixing portion of the other end is formed by joining.

그러나, 상기한 종래 간격유지구는 봉부재로 부터 납작한 판상의 내측 고정부를 형성하거나 납작한 판상의 부재로 부터 외측 고정부로서 콘형 체결부에 체결되기 위한 수나사가 형성된 캡를 형성하기 위한 제조공정이 복잡하고 시간과 비용이 많이 소요되는 문제로 단가가 상승되었다.However, the above-described conventional space maintenance tool has a complicated manufacturing process for forming a cap on which a male screw is formed to be fastened to a cone-shaped fastening part as an outer fixing part from a flat plate-like member or an inner fixing part from a flat plate-like member. The cost has increased due to time and cost.

또한, 종래의 타이볼트에서는 콘형 체결부가 제거된 콘크리트 벽체의 홈에 통상적으로 방수를 위해 실리콘으로 메우고 있으나, 시간이 지남에 따라 실리콘과 콘크리트 벽체의 홈 사이에 간격이 발생되어 우수가 침투되고 콘크리트에 매립된 상태로 잔류되는 타이볼트를 따라 유동하여 타이볼트가 부식되고, 녹물이 건물 외벽으로 누출되어 미관을 해치고, 녹물 제거를 위한 보수유지 비용이 증가되는 문제가 있었다. In addition, in the conventional tie bolt, the groove of the concrete wall where the cone-type fastener is removed is usually filled with silicone for waterproofing, but as time passes, a gap between the silicon and the groove of the concrete wall occurs, so that the rainwater penetrates into the concrete. There was a problem in that the tie bolts corroded by flowing along the tie bolts remaining in a buried state, the green water leaked to the outer wall of the building, thereby harming the aesthetics, and the maintenance cost for removing the green water was increased.
