摘要
The metric method for tying both sides of the fair face and rough wood formwork for concrete by using the metric ruler and the clamping device which doesn’t allow displacement. This current invention contributes in solving the technical problems in the previous ways which resample in the lack of accuracy to obtain vertical and horizontal alignment in the concrete walls, and the leak of large quantities of mortar between boards because of the use of iron bars between the boards that are to linked the spring clamp, and the other technical problems is the displacement in wood formwork during the casting process because of the wearing in spring clamp threads, and the high coast of using the previous methods. This current invention solve these problems its function is to control vertical and horizontal alignment in concrete walls with high accuracy due to the presence of the numbered metric ruler which obtain alignments so as to get the regular thickness concrete walls, and limit the displacement of formwork wood during with casting process, because of the clamping device which doesn’t allow that All parts which are used in this invention could be used longer and don’t need to be changed unless they are damaged of this needs long time and its distinguished by its high durability
