Embodiment Construction
[0027] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] Such as Figure 1 to Figure 4As shown, the embodiment of the non-stereotyped and revolvable formwork system used for the prefabrication of the stair section includes a horizontally fixed bottom form 1, a vertically placed side formwork 2, a step formwork 3, and end forms corresponding to both ends of the stair section 4; Bottom form 1, side formwork 2, step formwork 3 and end formwork 4 adopt wooden black formwork cutting saws, and its size and size are selected according to the design size of the prefabricated stair section, and described bottom formwork 1 is provided with the stair section Corresponding concave and convex structures, the bottom mold 1 is fixed on the pedestal 10 by screws, the step template 3 has multiple groups, the step template 3 is spliced by two mutually perpendicular two long strip templ...

The invention provides an atypical and cyclic template system for stair flight prefabricating, and solves the problem of longer stair flight manufacturing period of stairs at the construction site. The atypical and cyclic template system for stair flight prefabricating comprises a bottom mold horizontally fixed, a side template and pedal templates vertically placed, and end molds corresponding to two ends of a stair flight; multiple sets of pedal templates are provided; the pedal templates are spliced by two strip-shaped templates perpendicular to each other; all sets of pedal templates are tightly arranged to form a pedal structure of the stair flight; the side templates are plate-shaped structures; all sets of pedal templates are tightly arranged to form a saw tooth-shaped concave-convex structure; fixed parts are respectively arranged in recessed places formed on the outer side surfaces of the pedal templates; and split bolts are arranged between the side templates and the pedal templates. The atypical and cyclic template system for stair flight prefabricating realizes prefabricating of the stair flight at the construction site, and realizes batch production; the batch production of the stair flight can be performed beforehand at the construction site before production of a body structure; the concrete casting and the appearance molding quality can be guaranteed; the labor investment and the material waste can be reduced; and the construction cost is reduced.
Description
technical field [0001] The invention relates to the field of stair section prefabrication, in particular to an unshaped and turnable formwork system and a construction method for the prefabrication of staircase sections. Background technique [0002] Architectural stairs are a special structural component in a building. Its shape and structure are more complicated and its size requirements are more precise. At present, reinforced concrete cast-in-place stair sections are commonly used in construction projects. The formwork support of this kind of stair section is complicated during casting, and the formwork support and casting are easily affected by external environmental factors. It is difficult to guarantee the quality of the concrete appearance of the stair section. , at the same time, the stair section after casting needs a long time for maintenance, and it cannot be used as a transportation channel before the formwork is removed, which affects the construction period to...
