Construction method of assembled type prefabricated laminated slab for building

The invention provides a construction method of an assembled type prefabricated laminated slab for a building, which has high efficiency. The construction method comprises the following steps: step S11: providing a construction plane; distributing a plurality of construction points which are arranged into a matrix are distributed along the X and Y directions along engineering column screen cloth; setting column steel bars on the construction points and mounting a column template to surround the column steel bars; step S12: erecting a bracket between the two adjacent construction points in the X direction; mounting a main beam template is arranged on the bracket and mounting a beam steel bar in the main beam template; step S13: erecting a bracket between the two adjacent construction points in the Y direction, and mounting a secondary beam component on the bracket; step S14: mounting prefabricated slabs on the two adjacent brackets in the X direction; and step S15: erecting a bracket between the two adjacent construction points in the Y direction, and mounting a secondary beam component on the bracket. The construction method of the assembled type prefabricated laminated slab for the building has the advantages that the efficiency is high and the labor cost is saved.
