Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the reinforcement of the side formwork of concrete beams in building construction, and particularly relates to a reinforcement device for the side formwork of cast-in-place concrete beams. Background Art
[0002] At present, most houses in industrial and civil buildings still adopt cast-in-place structures. After the steel bars and formwork are installed in accordance with the construction sequence, concrete is then poured. The formwork on the side of the beam usually adopts the method of reinforcement with scaffolding pipes, wooden squares, tie bolts, and step-by-step clamps. As the main horizontal load-bearing member of the concrete structure, the concrete beam generally bears a large force, resulting in excessive deflection of the side formwork of the beam and excessive bending moment and shear force. During the pouring process, due to reasons such as load and vibration of the vibrating rod on the concrete, weak points at the junction of the beam and slab, and locations with large bending moments at the bottom of the beam are prone to formwork explosion and mortar leakage. Conventional step-by-step clamps and screw rods cannot reinforce the junction of the beam and slab, and this position is prone to formwork explosion due to excessive shear force. Currently, the formwork on the side of the beam usually adopts the method of reinforcement with scaffolding pipes, wooden squares, tie bolts, and step-by-step clamps. Such conventional methods cannot reinforce the junction of the beam and slab and the bottom of the beam, and conventional step-by-step clamps and screw rods cannot well reinforce the junction of the beam and slab. Content of the Utility Model
