Floor steel beam structure and floor steel beam construction method

Abstract

The invention provides a floor steel beam structure applied in the technical field of building construction. The invention also relates to a floor steel beam construction method. A left suspending lugplate (3) is arranged at the left end of each secondary beam (2) of the floor steel beam structure; a right suspending lug plate (4) is arranged at the right end of each secondary beam (2); each secondary beam (2) is arranged between the adjacent two main beams (1); the left end of the secondary beam (2) adopts a structure capable of being abutted against one main beam (1) through the left suspending lug plate (3); the right end of the secondary beam (2) adopts a structure capable of being abutted against the other main beam (1) through the right suspending lug plate (4). According to the floor steel beam structure and the floor steel beam construction method, the cost is slow, and the main beams can serve as temporary support to mount the secondary beams during floor mounting, so that hoisting machinery (a tower crane and a crane) can be separated from the secondary beams to perform other work; moreover, the secondary beams are not in the suspending state, and the construction safetyis improved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and more specifically relates to a floor steel beam structure, and also relates to a floor steel beam construction method. Background technique [0002] In the prior art, the floor steel girders of steel structure buildings are usually hoisted by hoisting machinery. After the secondary beam on the floor is hoisted to the installation position, workers install bolts or welding on the secondary beam. During the process of bolt installation or welding on the floor, the lifting machinery needs to hang the secondary beam all the time, and cannot perform other work until Secondary beam installation is complete. Such an installation method causes a waste of hoisting machinery, and the efficiency is not high. More importantly, there is a serious safety risk in the high-altitude construction environment where the hoisting machinery hangs on the floor. Contents of the invention [0003] T...
