Description
Technical field
The present invention relates to a kind of floor aluminum alloy pattern plate splicing formwork erecting structure system, be specifically related to a kind of floor aluminum alloy pattern plate splicing formwork erecting structure system being set up in the high-rise high building of precast beam unit, belong to technical field of civil engineering.
Background technology
The plurality of advantages such as aluminum alloy pattern plate formwork support process China is progressively popularized, and it has, and the number of turnover is many, formwork simple, economize on resources, are mainly used in the house and office building that structure is more regular, the number of plies is more at present.
But aluminum alloy pattern plate formwork system can't be suitable at present for the integral precast structure of employing precast beam, Bars In Poured Concrete Slab, and particularly for the building structure that floor height is higher, the original vertical support rod member of aluminum alloy pattern plate system will exist the great risk of unstability, cannot use.
Meanwhile, wholely water in structure reinforced concrete prefabricated, the connection between precast beam unit and slab form, often easily produce concrete spillage phenomenon, cause floor and beam junction to produce voids and pits phenomenon, there will be time serious and reveal muscle phenomenon.Mainly there is either large or small gap in the reason producing spillage, therefore, how effectively to block described gap according to slab form characteristic is the key point preventing concrete spillage between slab form and precast beam unit.
Between process precast beam unit and slab form, gap mainly contains following three kinds of ways at present: one is paste thicker double faced adhesive tape at slab form by precast beam unit side, spillage is solved by the viscosity of double faced adhesive tape, the method construction trouble relatively, double faced adhesive tape can not repeatedly use, and double faced adhesive tape removes difficulty; Two is adopt soft rubber bar pay the seam, and this way can exist and fails to fill in, or when concreting is vibrated, and rubber strip such as to get loose at the phenomenon, causes spillage still; Three is adopt to be enclosed within template with the sheet rubber of the bulk of slab form side-anastomosis, although this way spillage can solve, but cost is higher, and make sheet rubber slightly exceed template because sheet rubber is enclosed within template, cause reducing at the slab thickness of floor and beam junction, do not meet designing requirement and delivery receiving acceptance requirement.
Have again and be exactly, the connection between precast beam unit and precast plate, or the connection between precast beam unit and slab form, adopt the conventional braced structures being supported in lower floor's flooring or ground often to have the risk of unstability when building floor height is higher.Now there are three kinds of processing methods: one is carry out high-supported formwork calculating, require to set up high-supported formwork full hall scaffold according to high-supported formwork; Two is that prefabricated sill bolt chooses ear, to shelve precast plate; Three is reserved holes wearing scaffolding steel pipe on precast beam, shelves short scaffolding steel pipe in hole, on this steel pipe by hang under fastener parallel prefabricated beam length to scaffolding steel pipe, then shelve Encased truss on this steel pipe.
In said method, the first is too complicated, and cost is higher, and can not ensure formwork quality when constructing, and easily produces risk of caving in.In second method, the prefabricated complexity of precast beam of ear chosen by band, and cost is also higher.The third method Problems existing connects by hanging under fastener between scaffolding steel pipe, do not meet the safe handling requirement of fastener, easily occur that fastener gets loose phenomenon, security incident is caused to produce, and reserved hole is comparatively large, reserved construction trouble, and need later stage shutoff, otherwise perception is ugly, cost is easily higher.
