The present invention relates to a prefabricated anchor comprising: upper and lower rectangular frame bodies having upper and lower stages, which are connected to each other by welding horizontal frames (11, 11′) and vertical frames (12, 12′) at a predetermined vertical interval; a leg angle which is coupled to a region close to edges of the upper and lower rectangular frame bodies (10, 10′) by a bolt (21) and a nut (22), connects the upper rectangular frame body (10) with the lower rectangular frame body (10′), and supports the upper and lower rectangular frame bodies (10, 10′); a fixating plate (20a) coupled to the bottom of the leg angle (20); and multiple reinforcing bars for an anchor, which are vertically fixated by a fixating instrument (35) on the outside of the horizontal frames (11, 11′) and vertical frames (12, 12′) of the upper and lower rectangular frame bodies (10, 10′) at a predetermined interval. By not coupling the reinforced bars by welding, damage or heat deformation of the reinforced bars due to the welding heat can be prevented. Therefore, after forming the reinforced concrete bar, an anchor with excellent quality can withstand the upper and lower loads. Moreover, the manpower and time related to welding is reduced, thereby lowering price of products. |
