The invention discloses a construction method and structure of spliced type standard temporary houses. The construction method adopts a standard manufacturing mode, in the splicing process, only a framework adopts bolts for connection, other parts are all connected in a clamping or plugging mode, and the whole splicing process does not need welding. The framework is formed by bending and forming Q235 galvanized steel plates 3 mm thick overall, is high in strength and is not prone to rusting, thereby improving the circulation rate. All components are high in size accuracy and good in interchangeability, only galvanized bolts are adopted for connection in the splicing process, assembling and disassembling are simple, convenient and rapid, and the construction period is short. Combination is flexible, and office rooms, temporary meeting rooms, dormitories, dining rooms, bathrooms, toilets, standard rooms, power distribution rooms, water pump rooms and the like with different areas and different purposes can be obtained in a freely spliced mode. All wires are pre-buried in wall boards at a time when processed in a factory and do not need to be arranged on site. The construction method and structure of the spliced type standard temporary houses further have the characteristics of firmness, durability, dampproofness, wind resistance, fireproofness, corrosion resistance, heat insulation, sound insulation and heat preservation.
