Abstract

The invention discloses a steel structure formwork for a building stair. A base stair comprises a baseplate, a first vertical stair plate, a horizontal stair plate, first edge plates, first studs anda first insertion hole plate. The first vertical stair plate is fixedly connected to the upper end of the baseplate, the horizontal stair plate is fixedly connected to the right side of the upper endof the first vertical stair plate, and the first edge plates are fixedly connected to the front and rear ends of the horizontal stair plate respectively; the first studs are fixedly connected to the outer ends of the two first edge plates respectively, and the first insertion hole plate is fixedly connected to the right end of the horizontal stair plate; insertion columns are fixedly connected tothe front and rear ends of the lower end of a second vertical stair plate respectively, the two insertion columns are in clearance fit with and inserted in the front and rear ends of the first insertion hole plate respectively, and a second horizontal stair plate is fixedly connected to the right end of the upper end of the second vertical stair plate; second edge plates are fixedly connected to the front and rear ends of the second horizontal stair plate respectively, second studs are fixedly connected to the outer ends of the two second edge plates, and the two ends of either connection rodare inserted between the second studs and the first studs at the same side.

Description

technical field [0001] The invention relates to the construction field, in particular to a steel structure skeleton of a building staircase. Background technique [0002] The current stair installation structure includes stair treads and risers. The upper surface of the stair treads and the front end face are arc-shaped transitions. The front end is provided with a step nose extending downward and backward. A male mortise buckle matching with the female groove is fixed on the top; the stair installation structure of the invention has the advantage of ingenious structure and can prevent the stair treads from warping during use. But the regulation performance of this invention is general, and can not connect infinitely. Contents of the invention [0003] The object of the present invention is to provide a steel structure skeleton of a building staircase to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object,...
