Supporting structure for floor formwork of steel structure building and construction method

Abstract

The invention discloses a supporting structure for a floor formwork of a steel structure building. A floor surface of the steel structure building comprises a supporting system which comprises main beams and secondary beams, wherein the main beams and the secondary beams are H steels; the secondary beams are laid between the adjacent main beams; a formwork supporting structure comprises a plurality of formwork supporting cross beam arranged between the adjacent secondary beams, and a square timber; the top surface of the square timber butts against the bottom surface of the formwork, and the bottom surface of the square timber is arranged on the supporting cross beams; ejector rods are arranged on the lower planes of the secondary beams; and the supporting cross beams are laid on the ejector rods. A construction method comprises the steps of fixing the ejector rods on the lower planes of the secondary beams, laying the supporting cross beams on the corresponding fixed ejector rods, fixing square timber on the supporting cross beams and fixing the formwork on the square timber, casting a concrete layer on the formwork, prizing up the fixed ejector rods after the concrete layer is hardened and sequentially taking down the supporting cross beams, the formwork and the square timber. In the invention, the construction cost is saved, the construction progress is speeded up and the construction is safe.

Description

technical field [0001] The invention relates to a building floor formwork structure, more specifically a steel structure building floor formwork support structure, which belongs to the technical field of construction. Background technique [0002] With the widespread use of steel structure houses, the number of steel structure multi-storey houses has also increased. The level structure of the steel structure multi-storey building includes a bracket system and a concrete system. Since most of the steel structure houses have a large area, the bracket system generally includes a main beam and a secondary beam. The main beam spans the entire building, and the main beam is placed on the side of the building. wall or frame. The distance between the main beams can be 6-15 meters; the secondary beams are generally set between adjacent main beams (the secondary beams closest to the two sides are set between the main beam and the wall), and the distance between the secondary beams is...
