Description

Technical Field

[0002] Concrete cantilever structures are often used in projects such as building skywalks, observation decks, stair platforms, and are widely used.

[0003] For the existing concrete cantilever structure construction, the construction method is mostly to use an oblique support mechanism in combination with welding or to use a pull rod. For projects with tight schedules and heavy tasks, the above methods are not feasible. For the installation of cantilever oblique I-beams, when welding is used, the position cannot be fine-tuned after the cantilever structure is welded, and it cannot be dismantled after the construction is completed. Especially for the bottom support position, when the construction position is not accurate enough and needs to be forcibly dismantled, a large amount of material will be wasted, and the heavy load will further increase the difficulty of dismantling, seriously consuming labor costs and delaying the construction period.

[0004] Therefore, a new type of outward-projecting oblique I-beam bottom support device is needed to meet the usage requirements. Utility Model Content

[0007] Furthermore, the base assembly includes a bent base plate positioned and installed in cooperation with the lower concrete slab, a base plate, and a U-shaped anchor ring embedded in the lower concrete slab and connected and installed in cooperation with the bent base plate. The bent base plate as a whole is an L-shaped structure fitted and installed on the surface of the lower concrete slab.

[0008] Furthermore, the U-shaped anchor ring comprises a horizontal anchor ring and a vertical anchor ring, and the horizontal anchor ring and the vertical anchor ring are arranged perpendicular to each other and respectively cooperate with two surfaces of the bent substrate for positioning and installation.

[0009] Furthermore, the base plate includes a base plate body, an upper positioning foot extending horizontally along the base plate body and connected and installed in cooperation with the bent base plate, a lower positioning foot extending downward vertically along the base plate body and connected and installed in cooperation with the bent base plate, and a base plate ear protruding from the base plate body, and the base plate ear is connected and installed in cooperation with the I-beam positioning boot.

[0010] Furthermore, the horizontal anchor ring passes through the bent base plate and is fixedly connected and installed in cooperation with the upper positioning leg, and the vertical anchor ring passes through the bent base plate and is fixedly connected and installed in cooperation with the lower positioning leg.

[0011] Furthermore, the I-beam locating shoe includes a locating shoe body, a lower shoe mounting portion formed at the lower end of the locating shoe body and connected to the base assembly, and a locating protrusion installed on the locating shoe; the lower shoe mounting portion cooperates with the base assembly for angle adjustment and is positioned and locked by the locking piece.
