A concrete structure forming device, comprising: a frame assembly, comprising; a cross member having a first end and a second end, wherein the cross member at least one first connector positioned on a top side of the cross member, a first receiver connected to the first end of the cross member, wherein the first receiver is designed to receive a form, and a second receiver connected to the second end of the cross member, wherein the second receiver is designed to receive a form and is substantially parallel with the first bracket; and a hook, comprising; a handle, wherein the handle has a second connector designed to connect with the first connector of the cross member, and a hook extending from the handle in a predetermined direction relative to the handle, wherein the hook is designed to receive a reinforcement member.

A separable integrated type vibration isolator includes: divided vibration isolator units comprising casings having accommodation spaces formed open on tops thereof and reinforced concrete comprising reinforcing bars arranged in the accommodation spaces and the connection spaces and concrete cast in the accommodation spaces; casing connection parts for connecting the casings of the divided vibration isolator units to each other; reinforcing bar connection parts for connecting the reinforcing bars exposed to the connection spaces of the neighboring divided vibration isolator units to each other; and fillers adapted to be cast in the connection spaces where the plurality of divided vibration isolator units is connected to form reinforced concrete.

A free floating modular concrete footing system uniformly secures concrete forms without the need to secure vertical rods into the soil. A rigid form of a predetermined length spans atop a desired footing width to capture and secure opposing panels creating the footing form. Panels capable of supporting a concrete or similar matrix, are aligned on edge to create the desired form. The lower edge of a first panel form is in contact with the soil surface while the upper edge resides within a first channel of a modular concrete footing device.

In accordance with the present invention, an elevator core structure includes an elevator frame (120) separated from a main frame (110) and extending in a longitudinal direction of the main frame (110), and a guide frame (130) formed on an inner surface of the elevator frame (120). Here, the elevator frame (120) may be formed by stacking a plurality of frame segments (121), and a guide frame unit (131) forming the guide frame (130) may be mounted to one surface of each of the frame segments (121). The present invention exhibits an effect of early-constructing the elevator frame regardless of a construction schedule of a main frame of a building.
