Construction method of multifunctional tower crane used for building construction

Abstract

The invention discloses a construction method of a multifunctional tower crane used for building construction. The multifunctional tower crane comprises a base, a hanging rack, a balancing arm, an operation room and a cargo boom. The balancing arm and the cargo boom are erected on the two sides of the hanging rack correspondingly in a balanced mode. A water pipe is vertically arranged in the hanging rack. A water pipe is transversely arranged in the cargo boom. A plurality of spray nozzles are uniformly distributed in the water pipe transversely arranged in the cargo boom. A sliding device is arranged on a front boom body of the cargo boom. A lifting hook is arranged below the sliding device. A cable is arranged below the lifting hook. The cable is connected with a concrete stirring box. Monitoring probes are arranged at the tail end of the cargo boom and the lifting hook. By the adoption of the construction method of the multifunctional tower crane used for building construction, a lifting and conveying function is achieved, and poured concrete can be wet and cooled through watering by spraying water mist, or dust removal can be achieved through mist spraying.

Description

technical field [0001] The invention belongs to the field of building construction equipment, in particular to a construction method of a multifunctional tower crane for building construction. Background technique [0002] The tower crane is a kind of lifting equipment commonly used in the construction process at present. Its structure is that a balance arm, a lifting arm and an operating room are arranged on the hanger, the lifting arm is provided with a hook, and the balance arm is provided with a counterweight. When lifting heavy objects, the bending moment on the foundation is relatively large, so the requirements for the treatment of the foundation are very high. Generally, the tower crane can only lift materials, steel bars, plates, etc., and cannot perform high-altitude concrete pouring work, and cannot be used for pouring. The concrete infiltration, cooling, and the utilization rate of the tower crane are low. When the tower crane is working on a high-rise constructi...

[0002] The tower crane is a kind of lifting equipment commonly used in the construction process at present. Its structure is that a balance arm, a lifting arm and an operating room are arranged on the hanger, the lifting arm is provided with a hook, and the balance arm is provided with a counterweight. When lifting heavy objects, the bending moment on the foundation is relatively large, so the requirements for the treatment of the foundation are very high. Generally, the tower crane can only lift materials, steel bars, plates, etc., and cannot perform high-altitude concrete pouring work, and cannot be used for pouring. The concrete infiltration, cooling, and the utilization rate of the tower crane are low. When the tower crane is working on a high-rise construction site, because it is far from the ground, it is generally operated by the ground staff through the walkie-talkie or based on visual inspection. It is very unscientific and prone to accidents. , causing casualties
