Device for realizing operation of mobile tower crane on structural floor and construction method

Abstract

The invention discloses a device for realizing operation of a mobile tower crane on a structural floor and a construction method. The device comprises transfer beams, track beams and guide tracks. A plurality of parallel transfer beams are arranged on floor structure columns. Two parallel track beams which are used for installing the guide tracks are perpendicularly laid between the transverse beams. The construction method of the device for realizing operation of the mobile tower crane on the structural floor mainly comprises the following steps of: 1, setting the positions of the transfer beams and the track beams according to building floor structure layout; 2, calculating specifications of the transfer beams and the track beams according to wheel pressure, wind load and braking force of the used mobile tower crane; 3, installing embedded parts on the floor structure columns at the positions where the transfer beams are required to be fixed; 4, installing the transfer beams and the track beams; and 5, laying the guide tracks. The device for realizing operation of the mobile tower crane on the structural floor and the construction method have the advantages that the structure construction difficulty caused by large single-layer building area is overcome, the investment on mechanical equipment during construction is reduced, the construction period is shortened, the construction cost is saved and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device and a construction method for realizing the operation of a mobile tower crane on a structural floor. Background technique [0002] In recent years, with the development of the national economy, in order to meet people's needs, the single-story area of ​​a large number of public buildings such as airports, railway stations, exhibition centers, and shopping malls has become larger and larger. These buildings have some common characteristics. The substructure For 2 to 3 floors or a large basement, the roof adopts a large-span steel structure to realize the use of a large space in the building, which makes the roof steel components unable to be installed or the installation cost is very high due to the limited coverage of the crane or the lifting performance , The problem of long construction period. [0003] In the construction of construction projects, mobil...
