Compared with prior art the utlity model has following characteristics and beneficial effect:
(1), steel concrete independence winding stair shape is comparatively complicated, its template adopts steel sheet to add the die type design of light section shaped steel, has saved disposable only in a large number timber, each steel part is reusable, has reduced construction costs.
(2), because die type formwork can be processed the worker in advance makes, and each position adopts the convenient bolt connecting mode of installing and removing, and shortened the time of formwork erection and dismounting, saved the time that on-the-spot formwork is reinforced, save labour cost, shortened the duration, accelerated speed of application.
(3), because the connected mode of die type formwork is very solid and reliable, and independent winding stair scaffold only installs vertical bearing frame and get final product, need not template is reinforced, saved the material and the installation manpower of scaffold reinforcement system.
(4), the design of the die type of template installs than common templates and improved precision, promptly having improved the construction quality of independent winding stair, particularly presentation quality has more significantly and improves.
(5), mould bases installs more simple and reliablely, improved safety of construction.
(6), the utlity model has tangible economic benefit: through preliminary comprehensively measuring and calculating, independently revolve and adopt the design of template mold formula, save working measure expense 35% than adopting wooden model, foot rest pipe to reinforce.
The utility model die type special applicable to various constructions of structures and complex region independence winding stair template designs, and has not only improved construction quality and construction speed, has also reduced construction cost simultaneously.
