Abstract

본 발명은 구조용콘크리트 및 구조용콘크리트의 가공방법 및 구조용콘크리트의 가공에 사용하는 지석(지석숫돌)차에 관한 것으로서, 원판상의 플레이트와 이 플레이트의 외주에 설치한 외주지석과 상기한 플레이트의 양측면에 설치한 한쌍의 내주지석을 가지고 이 한쌍의 내주지석의 노출측면간의 거리를 상기한 외주지석의 두께보다도 크게 설정하고 한쌍의 내주지석과 외주면과 상기한 한 노출측면과의 경계부에 원주방향에 따라 라운딩부 또는 경사면을 설치한 구조용콘크리트의 가공에 이용하는 지석차를 제공하여 홈의 각부에 라운드부를 갖는 면취부를 형성시킴에 따라 각부에 최소단면적 면취부에 의하여 강도를 향상시키고, 따라서, 외부에서 가해지는 충격 또는 하중에 의한 각부가 파손 및 크랙발생이 방지되어 콘크리트의 표면 평면성 및 외관을 최소의 상태로 유지할 수 있으며, 또한 본 콘크리트의 표면에 홈파는 가공을 행하면서, 이 홈의 각부에 소정형태의 라운드부가 형성되는 면취부 가공을 행하므로 1회의 가공동작으로 홈가공 및 면취부위 가공을 동시에 행하므로서 가공효율이 좋고, 가공시간의 단축과 가공코스트의 억제를 실현할 수 있다.The present invention relates to a method for processing structural concrete and structural concrete, and a grindstone (grindstone) difference used for processing structural concrete, which is provided on a plate of a disc and outer peripheral stones installed on the outer circumference of the plate and on both sides of the plate. With a pair of inner circumferential grindstones, the distance between the exposed side surfaces of the pair of inner circumferential grindstones is set to be larger than the thickness of the outer circumferential grindstone, and the pair of inner circumferential grindstones and the outer circumferential surface and the rounded portion along the circumferential direction at the boundary between the exposed side Or by providing a grindstone used for the processing of structural concrete with a sloped surface to form a chamfer having a rounded portion at each corner of the groove, thereby improving the strength by the minimum cross-sectional chamfered portion at each corner, and thus impact or external impact Each part is prevented from being broken and cracked by load, so The external appearance can be kept to a minimum, and the groove wave is machined on the surface of the concrete, and the chamfering part in which the round part of the predetermined shape is formed in each groove portion of the groove is performed so that the groove processing and the chamfering are performed in one machining operation. By simultaneously processing the part, the machining efficiency is good, and the machining time can be shortened and the machining cost can be suppressed.
