Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] Such as figure 1 As shown, a prefabricated stair section and construction method of a non-stereotyped, revolvable formwork system, its composition includes: a pedestal 16, a bottom form 15 fixed on the pedestal, an integral stair slab assembled from a single tread plate 6, and a combined fixing frame 14. The stair boards are vertically matched and installed on the bottom form 15, a set of combined fixing frames 14 are fixed on the stair boards along the...

Abstract

The invention discloses a precast stair flight manufactured by a non-established and circularly-used template system and a construction method. Each precast stair flight comprises a pedestal, a bottom die fixed on the pedestal, an overall stairboard spliced by a single step plate and a combination of fixing racks. The stairboard is installed on the bottom die in the mode of vertically matching. The combination of fixing racks is fixed on the stairboard along a horizontal direction. The distance between every combination of fixing racks and the vertical direction of the stairboard is the same. The precast stair flight manufactured by the non-established and circularly-used template system and the construction method have following beneficial effects: based on technological summary and innovation, the non-established and circularly-used template system is adopted to precast stair flights on the construction site; while ensuring the concrete forming quality of each stair flight in the first place, a working period is effectively shortened, construction cost is lowered and refuse discharge of construction waste on the site is reduced at the same time.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a prefabricated stair section of a non-stereotyped, turnable formwork system and a construction method. Background technique [0002] At present, reinforced concrete stair steps in construction projects generally adopt the cast-in-place method. The formwork support is complicated and greatly affected by external environmental factors. channel, which affects the construction period to a certain extent. [0003] Factory prefabricated stair sections have high production efficiency and easy control of component quality, but the initial equipment, plant and other investment and operating costs are high. Without mandatory promotion policies or subsidies, the number and scale of prefabricated component factories cannot meet the needs of existing projects . Contents of the invention [0004] In order to solve the problems in the prior art that the appearance molding quality is di...
