Manufacturing method of prefabricated stair section and prefabricated stair section

Abstract

The invention discloses a manufacturing method of a prefabricated stair section and the prefabricated stair section. The manufacturing method comprises the following steps that S100, an assembly platform is built, and an outer contour line is drawn on the assembly platform; S200, a jig frame is erected according to the outer contour line; S300, a bottom plate is erected on the jig frame, and the vertical projection of the bottom plate coincides with the outer contour line; S400, web plates are erected on the bottom plate; S500, a top plate is erected on the web plated, the vertical projection of the top plate coincides with the outer contour line, and the bottom plate, the web plated and the top plate form a ladder beam; and S600, a pedal is erected on the top plate, and the bottom plate, the web plates, the top plate and the pedal form ladder beams. According to the manufacturing method, one coordinate system is adopted for manufacturing of the stair beams and laying of the pedals, so that the overall manufacturing precision of the prefabricated stair sections is guaranteed, and the precision requirement of customers for the prefabricated stair section is met; and meanwhile, the prefabricated stair sections are manufactured, the situation that a jig frame in the prior art is independently erected, and consequently site occupation and waste of related materials are caused are avoided, and the bottom plate, the web plates and the top plate are light in weight and can be conveniently hoisted to the jig frame.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a method for manufacturing a prefabricated ladder beam section and a prefabricated staircase section. Background technique [0002] In the related technology, during the production process of the prefabricated stair section, refer to figure 1 and figure 2 , when the ladder beam is made, the first carrier frame 10 and the first contour line are used, so that the ladder beam can be quickly produced; thereafter, the second carrier frame 20 and the second contour line are used, and the second tire frame 300 is used for the ladder beam 100 Positioning, so that the treads can be horizontally set up on the ladder beam 100, and then the production of the prefabricated stair section can be completed; however, the above method is used to manufacture the prefabricated stair section, and the assembled tire frame is converted twice, and the assembly coordinate system changes, which affect...
