A prefabricated house and its construction method

Abstract

The invention provides a prefabricated house and a construction method thereof. The house comprises a house foundation, wherein a foundation connecting piece is embedded in the house foundation; the foundation connecting piece is provided with vertical precast columns; the precast columns are arrayed vertically and horizontally; the precast columns in the same vertical direction are sequentially superposed; horizontal precast beams are arranged among the tops of the adjacent precast columns in the same layer so as to form a house frame; the house frame consists of multiple unit layers; each unit layer comprises multiple unit rooms; <0}{0><}0{>the precast beams in each unit layer are provided with precast prestressed concrete composite floor slabs; anchor bars at two ends of the precast prestressed concrete composite floor plates are fixedly connected with floor slab connecting pieces reserved on the precast beams; vertical precast partition plates are arranged among the adjacent unit rooms; the outer side of the house frame is provided with a precast large out-hung panel; a precast stair plate is arranged between every two upper and lower unit layers. <0}{0><}0{>The construction method is capable of improving the use area of the house, and the prefabricated house is low in construction cost and good in fire resistance.

Description

technical field

[0001] The invention relates to the field of construction, in particular to a prefabricated house and a construction method thereof. Background technique

[0002] In the construction of high-rise and super high-rise buildings, the traditional construction method is on-site construction, and reinforced concrete frame or frame-shear structure can be used; in addition, there are very few steel structures. If a reinforced concrete frame or frame-shear structure is used, usually because the cross-sectional area of ​​the beams and columns is too large, it will occupy the actual use space and form "fat beams and columns"; moreover, this kind of "fat beams and columns" will make The use space of the house is irregular, which brings inconvenience to the residents. At the same time, because the solidification of the concrete takes time, and it is not suitable for construction at low temperature, the construction speed of the building is limited. Moreover, in traditio...
