The invention discloses a steel corbel pre-embedded structure and a construction method thereof. The steel corbel pre-embedded structure comprises a concrete column, a corbel transverse steel plate, acorbel transverse connection steel plate and two corbel vertical steel plates. The two corbel vertical steel plates are inverted L-shaped plate structures arranged symmetrically, the vertical corbeltransverse connection steel plate is connected between the middle parts of the corbel vertical steel plates in a welded mode, one ends of the corbel vertical steel plates extend into the concrete column, and the other ends of the corbel vertical steel plates are located on the side edge of the concrete column. The corbel transverse steel plate is connected to the top ends of the outer sides of thecorbel vertical steel plates in a welding mode, pre-embedded steel pipes are arranged in the concrete column, split finish rolling threaded steel is arranged in the pre-embedded steel pipes, the thread steel is fixed through screw nuts after penetrating through preformed holes of the corbel transverse connection steel plate. Through the pre-embedded steel pipes and the split finish rolling threaded steel, and the tensile stability of the structure is ensured; and through a pre-embedded steel plate box, the corbel steel plates are inserted into the pre-embedded steel plate box, the steel plates is used for bearing the shear force to ensure that properties of materials are well used, and good using effects are obtained.
Description
technical field [0001] The invention relates to a corbel, in particular to a pre-embedded steel corbel structure and a construction method thereof, and belongs to the technical field of construction of foundationless support structures for construction, municipal administration, highways and railways. Background technique [0002] At present, the construction of non-foundation support structures such as highways, municipalities, and railways basically uses holes in the formwork to embed bolts or reinforced corbels with section steel to form a support system. After the concrete pouring is completed, the formwork is difficult to dismantle, and the formwork is seriously damaged and cannot be reused, resulting in a serious waste of resources; pre-embedded bolts or section steel bear a large shear force, and the poor shear performance of bolts or section steel poses a great safety hazard . Contents of the invention [0003] The technical problem to be solved by the present inv...
