Technical field
This utility model relates to a kind of overall assembled floor of building industry, and specifically a kind of periphery overlapping is whole
Body assembled floor and construction method thereof.
Background technology
Building floor typically uses on-the-spot integral cast-in-situ floor, prefabricated hollow floor or superimposed sheet at present, its
Middle cast-in-situ floor has an advantage that globality is strong, stress performance is good, but due to its steel bar meter, colligation,
Template construct completes with maintenance molding the most at the construction field (site) with support, concreting, needs bigger material
Stack and materials processing place and substantial amounts of artificial input, therefore, often result in each operation in construction the most dry
Disturbing, construction quality is difficult to ensure, and situ wet workload is big, and building waste is piled up, and has a strong impact on construction field
Ground and surrounding enviroment, cause environmental pollution.Although and prefabricated hollow floor easy construction, but large area building
Plate due to temperature, shrink the crack that may produce in overlapping district, floor cracking phenomena is more universal and globality
Poor.The most conventional laminated floor slab is generally divided into two-layer, bottom band bar-mat reinforcement prefabrication, and top layer is on-the-spot
Pour.Its situ wet work operations amount is big, and assembly rate is low, and when floor is installed, rigidity is little, inapplicable opens greatly
Between building.

In this utility model, described floor construction layer 1 is unidirectional or bidirectional hollow precast floor slab, in floor
Portion's preheating embedding line.
Further, overall assembled floor of the present utility model also includes being arranged on floor construction layer 1
Floor decorative layer 2, described floor decorative layer 2 and floor construction layer 1 together prefabricated construction, or at floor construction
Shop is carried out again after layer 1 construction.
This utility model additionally includes the construction method of the overall assembled floor of a kind of above-mentioned periphery overlapping, bag
Include following steps:
The first step, above-mentioned prefabricated periphery is overlapped overall assembled floor on-site hoisting put in place, be placed on and take
On the wallboard built；
Second step, longitudinal reserved steel bar of the reinforcing bar and wallboard that will water overlapping region after floor are installed and are combined；
3rd step, by prestressed cable by floor periphery to install the drag-line placed in the middle of suspension ring and wallboard solid
Determine device to connect, then by jack by the installation suspension ring of drag-line fixing device tension floor periphery, to floor
Overall Shi Hanzhang；
4th step, carry out concreting to watering overlapping region after floor periphery, floor and wallboard are tied
It is combined；
5th step, unclamp prestressed cable, to watering overlapping band Shi Hanzhang after pouring；
6th step, to after water the flooring of overlapping region and fit up, and to non-precast floor slab decorative layer
Floor carries out the construction of decorative layer.
Wherein, the concrete poured described floor slab back casting overlapping region in the 4th step is that microdilatancy is from close
Real concrete.
Floor system in this utility model uses major part prefabrication to produce, and can realize finishing, pipeline
Pre-buried and structure-integrated, it is greatly improved assembly rate, after reserved, water overlapping district, strengthen floor and wall
The globality that body connects.At the scene in work progress can to assembled floor Shi Hanzhang of the present utility model,
Strengthen the position, overlapping district of weakness, be greatly improved the cracking resistance in floor overlapping district, to overcome existing skill
Floor and wallboard that art exists overlap the defect that district is easy to crack.
