Cantilevered floor slab rebar structure adopting steel bar truss formworks and bar reinforcing method

Abstract

The invention discloses a cantilevered floor slab rebar structure adopting steel bar truss formworks and a bar reinforcing method. The problem that support formworks of a cast-in-place cantilevered reinforced concrete floor slab of an existing high-altitude cantilever floor have support difficulties and are long in construction period and high in construction price is solved. A main building structure (8) is included, a steel beam cantilever frame composed of steel beams (9) parallel to the main building direction and steel beams (10) perpendicular to the main building direction is arranged onthe outer side of the main building structure (8) in an overhang manner, steel beam panels (11) parallel to the main building direction are arranged on the steel beams (9) parallel to the main building direction, and steel beam panels (13) perpendicular to the main building direction are arranged on the steel beams (10) perpendicular to the main building direction, the steel bar truss formworks are fixedly welded to the steel beam cantilever frame and are composed of rectangular bottom mold steel plates (1) and steel bar framed bents fixedly arranged in the left-right direction at intervals,and the steel bar framed bents are fixedly arranged on the rectangular bottom mold steel plates in the left-right direction. The on-site reinforcement lashing workload can be reduced by 60% to 70%.

Description

technical field [0001] The invention relates to a concrete pouring formwork, in particular to a reinforcement structure and reinforcement method for a concrete floor slab of a cast-in-place high-position cantilevered building. Background technique [0002] In the existing tower structure, a high-altitude large-span cantilevered building structure is often designed. The high-altitude large-span cantilevered building is generally supported by a steel structure frame, and cast-in-place reinforced concrete beams, slabs, and external frame beams; for cast-in-place cantilevered reinforced concrete If the floor is constructed with traditional wooden formwork, it cannot meet the support strength of the bottom formwork of the cast-in-place reinforced concrete floor at the bottom of the high cantilevered building. The existing technology is to use profiled steel plates as the bottom formwork, but when the bottom of the floor is encountered, the formwork cannot be set. When supporting ...
