Novel fixing device for hoisting reinforcing steel bars for building construction

Abstract

For solving the problem that a reinforcement cage is not easy to hoist, the invention discloses a novel fixing device for hoisting reinforcing steel bars for building construction. The fixing device comprises a first cross rod and a second cross rod, wherein two ends of the first cross rod and the second cross rod are connected with a second connecting ring and a first connecting ring, a rotating shaft is sleeved with the second connecting ring, the surface of the rotating shaft is fixedly sleeved with a second rotating disc, a motor is sleeved with the first connecting ring, a first rotating disc is installed behind the motor, a conveying belt is connected between the first rotating disc and the second rotating disc, hydraulic cylinders are symmetrically installed in the middle of the first cross rod and the middle of the second cross rod, piston rods are installed on the outer sides of the hydraulic cylinders, a top plate is fixedly installed at the outer ends of the piston rods, insertion teeth are evenly welded to the outer surface of the top plate, and a first sleeve is fixedly installed on the surface of the first cross rod. According to the fixing device, the conveying belt is controlled by the motor, and the hydraulic cylinders are matched with the top plate and the insertion teeth, so that the stability on reinforcing steel bar hoisting is improved, and the hoisting of a reinforcement cage is realized.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a novel fixing device for lifting steel bars used in building construction. Background technique [0002] The main function of the reinforcement cage is the same as that of the vertical reinforcement of the column. It mainly plays a role in tensile strength. The compressive strength of concrete is high but the tensile strength is very low. It acts as a constraint on the concrete of the pile body so that it can bear a certain axial tension. During the construction of bridges, culverts or high-rise buildings, the foundation may be required to be piled according to requirements. The method is to use machine punching and water mill drilling, and the hole depth meets the design requirements, and then lower the reinforcement cage to the pile hole, and then insert the conduit for concrete pouring. In addition, when the concrete structure is a column or strip member, the central par...

Problems solved by technology

[0003] However, the steel cage is generally relatively high, and it is inconvenient to lift the steel cage when it is lifted. Generally, the steel cage is lifted vertically. Because it is relatively high, the top of the steel cage is usually hung for lifting. The steel cage is relatively heavy, so it will fall off during hoisting. If the steel cage falls, the relatively light result is that the welding position will crack, making the steel cage loose, and it may also hit people, which is more dangerous. Therefore, It is urgent to design a new type of fixing device for lifting steel bars used in building construction to solve the lifting problem of steel cages
