Description

A kind of floor aluminum alloy pattern plate splicing formwork erecting structure system
Technical field
The utility model relates to a kind of floor aluminum alloy pattern plate splicing formwork erecting structure system, is specifically related to a kind of floor aluminum alloy pattern plate splicing formwork erecting structure system of the high-rise high building that is set up in precast beam unit, belongs to technical field of civil engineering.
Background technology
The plurality of advantages such as aluminum alloy pattern plate formwork support process China is progressively universal, and it has, and the number of turnover is many, formwork simple, economize on resources, main use in more regular in structure, the number of plies is more house and office building at present.
But aluminum alloy pattern plate formwork system can't be suitable at present for the integral precast structure that adopts precast beam, Bars In Poured Concrete Slab, and particularly for the higher building structure of floor height, the original vertical support rod member of aluminum alloy pattern plate system, by there being the great risk of unstability, cannot use.
Meanwhile, reinforced concrete prefabricated whole watering in structure, being connected between precast beam unit and slab form, often easily produce concrete spillage phenomenon, cause floor and beam junction to produce voids and pits phenomenon, when serious, there will be and reveal muscle phenomenon.The reason that produces spillage is mainly between slab form and precast beam unit, to have either large or small gap, and therefore, how effectively to stop up described gap according to slab form characteristic is the key point that prevents concrete spillage.
On gap between processing precast beam unit and slab form, mainly contain at present following three kinds of ways: the one, paste thicker double faced adhesive tape at slab form by precast beam unit one side, viscosity by double faced adhesive tape solves spillage, the method construction trouble relatively, double faced adhesive tape can not be repeatedly used, and double faced adhesive tape is removed difficulty; The 2nd, adopt soft rubber bar pay the seam, this way can exist and fail to fill in, or in the time that concreting is vibrated, and the rubber strip phenomenon such as get loose, causes spillage still; The 3rd, adopt the sheet rubber of the bulk identical with slab form side to be enclosed within template, although this way spillage can solve, but cost is higher, and because being enclosed within template, sheet rubber make sheet rubber slightly exceed template, cause reducing at the slab thickness of floor and beam junction, do not meet designing requirement and delivery receiving acceptance requirement.
Have to be again exactly, being connected between precast beam unit and precast plate, or being connected between precast beam unit and slab form, when building floor height is higher, adopt the conventional braced structures that is supported in lower floor's flooring or ground to tend to the risk of unstability.Now there are three kinds of processing methods: the one, carry out high-supported formwork calculating, require to set up high-supported formwork full hall scaffold according to high-supported formwork; The 2nd, prefabricated sill bolt is chosen ear, to shelve precast plate; The 3rd, on precast beam, the reserved hole of wearing scaffolding steel pipe is shelved short scaffolding steel pipe in hole, on this steel pipe by under fastener, hang 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 formwork quality can not guarantee to construct time, easily produces the risk of caving in.In second method, the prefabricated complexity of precast beam that band is chosen ear, cost is also higher.The problem that the third method exists is by hanging and connect under fastener between scaffolding steel pipe, do not meet the safe handling requirement of fastener, be prone to the fastener phenomenon that gets loose, cause security incident to produce, and reserved hole is larger, reserved construction trouble, and need later stage shutoff, otherwise perception is ugly, cost is easily higher.
