The invention provides a coach body structure. The coach body structure comprises a chassis, a four-periphery framework, and a top arch framework and is characterized in that: the coach body structure is formed by riveting aluminum alloy sections; the four-periphery framework consists of a grating framework consisting of vertical columns and transverse beams; and the section of each vertical column has a shape of a hollow rectangular ring, and the short side of the rectangular ring is extended outward from two ends respectively to form two wing parts. An aluminum alloy full-integral coach body is adopted, so that the weight of the whole coach is reduced, the number of passengers is increased, fuel oil consumption is reduced, and the emission of the whole vehicle is greatly reduced; an aluminum alloy structure ensures that the service life of the coach is prolonged; the coach has the aluminum alloy structure, so that electrophoresis and rust prevention is avoided during production of the coaches, the production cost is saved, and industrial emission is reduced; and a riveting mode is adopted by the whole lightweight coach body structure, so that complex and expensive welding equipment is not needed any more and production cost is saved.

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.
