Description

A kind of overall assembled floor of periphery overlapping
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.
Utility model content
This utility model solves the technical problem that and is: for existing on-the-spot integral cast-in-situ floor, precast hollow building The drawbacks described above that plate or superimposed sheet exist, it is provided that one is capable of that good integrity, crack resistance be strong, assembly rate High overall assembled floor, to meet the demand of house building industry modernization.
This utility model adopts the following technical scheme that realization:
This utility model includes a kind of overall assembled floor of periphery overlapping, and described floor is prefabricated prestressing force Or non-prestressed floor, after the upper strata periphery of floor construction layer 1 is reserved, water overlapping band 14, described after water folded Crossed belt 14 is the shaped as frame empty portions being positioned at floor upper strata periphery, waters for carrying out scene with body of wall, beam Build.
Further, the hogging moment area steel bar stress that described floor slab back casting overlaps with 14 uses prefabricated and on-the-spot peace Pretending combination, bar splicing position is crisscross arranged in nearly zero moment of flexure position, or interval set up negative reinforcement with Neighbouring floor connects.
Further, it is spaced or is abound with between the levels bar-mat reinforcement of described floor construction layer 1 continuously erection is set Muscle, described bearing rod forms space bar-mat reinforcement together with steel bar stress, distribution bar.
Preferably, watering the width overlapped with 14 after described is L/5~L/4 (L is floor effective span).
Further, vertically integrated pre-buried installation suspension ring of described floor construction layer 1 periphery, for floor Lift and plate periphery concrete is applied precompression.
Further, water the overlapping slab surfaces with 14 places after described and make coarse process.
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.
Compared with prior art, this utility model has the advantages that
(1) sound insulation of floor, decoration, pipe built-in produce with structure-integrated prefabrication, and assembly rate can Reach more than 85%.
(2) after reserved, water overlapping band, the globality that floor is connected with wall, beam can be strengthened.
(3) Shi Hanzhang can be passed through, the cracking resistance in floor overlapping district can be improved.
Thus visible, the overall assembled floor of the periphery that the utility model proposes overlapping, compare traditional prefabricated Floor, the integrated precast floor construction of the high assembly rate of the periphery overlapping of this utility model patent, can realize The standardized production of factory and effective mass control, the precast floor slab installed according to this utility model and wall, beam The globality connected and the crack resistance in overlapping district are more preferable, and the higher feature of assembly rate can be generally applicable to assembling In formula building.
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
