Externally-hung infilled wall structural system of steel framework, assembly-type infilled wallboard and construction method

Abstract

The invention relates to an externally-hung infilled wall structural system for an assembly-type steel framework. The system comprises the rectangular steel framework and the infilled wallboard. The steel framework is formed by connection of steel framework columns and steel framework beams. The inside of an upper steel framework beam at the upper part is connected with first angle iron connectingpieces by welding. The inside of a lower steel framework beam is connected with second angle iron connecting pieces by welding. The infilled wallboard is arranged outside the steel framework and connected between the upper steel framework beam and the lower steel framework beam. Four corners of the infilled wallboard are equipped with first screw rods and second screw rods in a pre-buried manner.The bottom of each rectangular connection board is connected with a first screw rod. The top of each rectangular connection board is connected with the upper steel framework beam through a third screw rod. Each second screw rod is connected with each second angle iron connecting piece. In case of a horizontal earthquake, the wallboard and the steel framework are deformed so that anti-earthquake performance is improved. During the force-bearing process of screw rods, surrounding concrete is not affected so that concrete is prevented from cracking.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a filling wall structure system, a filling wall board and a construction method thereof. Background technique [0002] At present, the frame-fill wall structure system is a commonly used structural system. Due to the neglect of the fill wall in the design and construction process, the damage of the fill wall during the earthquake is very serious. [0003] From a design point of view, for the frame-filled wall structure system, the filled wall is usually directly acted on the main structure as a line load, without considering the influence of the filled wall on the main structure, which is inconsistent with the actual force of the structure, so the seismic damage of the filled wall is compared serious. [0004] From the perspective of construction, most of the current filling walls adopt masonry structure, using small concrete blocks or perforated bricks, etc. The construc...

Problems solved by technology

[0006] The purpose of the present invention is to provide a steel frame external infill wall structure system, an assembled infill wall panel and a construction method, to solve the problem that the infill wall directly acts on the main structure as a line load in the existing frame infill wall structural system, and is affected by the actual situation. The strength does not match; the infill wall adopts a masonry structure, the construction process is cumbersome, the construction quality is not easy to guarantee, the interface bond strength between the block and the mortar is relatively low, and slippage is prone to occur during an earthquake; the masonry infill wall and the main frame are used When the steel bars are connected, the infill wall and the frame cannot be deformed synergistically during an earthquake, there is no relative displacement and corner, and the infill wall is seriously damaged.
