1. A stack-assembly-type apparatus for supporting a formwork, the stack-assembly-type apparatus comprising:
a support frame (100) comprising a front vertical frame (10) positioned at a rear surface of a formwork (2), a rear vertical frame (20) positioned at rear of the front vertical frame, and a connection frame (30) connecting the front vertical frame (10) to the rear vertical frame (20) in a square form;
front and rear pipe fixing parts (40 and 50) configured to couple and assemble at least one support frame (100) provided in parallel in left and right directions to front and rear connection pipes (200 and 200′) provided in left and right directions at front and rear portions of the support frame (100); and
front and rear vertical assembling parts (60 and 70) configured to connect and assemble the support frame (100) to another support frame (100) by vertically stacking the support frames (100),
wherein, in the front vertical assembling part (60), a connection part (11) is located on an upper portion of the front vertical frame (10) and extends upward higher than an upper end of the rear vertical frame (20), and left and right brackets (61 and 61′) configured to be connected to a lower connection frame (30-1) and extend in the left and right directions, and
the left and right brackets (61 and 61′) of the front vertical assembling part (60) are configured to be inclined and connected to each other by both the lower connection frame (30-1) and an inclination part (61a), an assembly part (65) comprising an inclination surface corresponding to the inclination part (61a) of each of the left and right brackets (61 and 61′) and a coupling hole (66) located perpendicularly to the inclination surface is securely provided on the upper portion of the front vertical frame (10) and is inserted between the left and right brackets, and a fastening screw rod (67) that is supported such that an upper end thereof is blocked to upper ends of the left and right brackets (61 and 61′) by a support washer (67a) and is screw-coupled to the coupling hole (66), so that the front vertical assembling part (60) is vertically fixed, and
wherein the front pipe fixing part (40) has a pipe insertion groove (41) at a position between the upper portion of the front vertical frame (10) and an upper connection frame (30-2), and the front connection pipe (200) is inserted into the pipe insertion groove (41), the pipe insertion groove (41) being configured such that a fore end of a clamping bolt (43) that is screw-coupled to a screw hole (42a) of a first fixing means (42) in the rear of the pipe insertion groove (41) fixes the front connection pipe (200) by applying pressure thereto, and
the rear pipe fixing part (50) is configured such that, a second fixing means (45) in which a pipe insertion groove (46) is formed to be open upward is securely provided on a rear surface of an upper portion of the rear vertical frame (20), and the rear connection pipe (200′) is inserted into the pipe insertion groove (46), and a fore end of the clamping bolt (43) that is screw-coupled to a screw hole (45a) located at the rear of the pipe insertion groove (46) fixes the rear connection pipe (200′) by applying pressure thereto.
