Abstract:
An insulation roof or floor panel for construction of a composite insulated concrete roof or floor includes two elongated studs, each having a web section and upper and lower flanges, a plurality of deformation resistant elements protruding from the upper flange of the studs and spaced apart along the upper flange of each stud, and an insulation board secured between the two elongated studs. The insulation board has a thickness less than the width of the web section of the studs, with the lower surface of the insulation board against the upper flanges of the studs, thereby establishing a distance between the upper surface of the insulation board and the upper flanges of the studs. Further provided are a composite insulated concrete roof or floor system with enhanced resistance to deformation, constructed using the insulation roof or floor panel, and the method of construction.
Abstract:
A concrete load-bearing wall with compound heat-insulating layer includes wall body (1) and connecting beam (2). Two layers of prefabricated heat-insulating concrete wall bodies (11a, 11b) are set in the wall body (1) of external wall, said prefabricated heat-insulating concrete wall body (11a, 11b) is a concrete plate (5) whose external surface is covered with a heat-insulating material layer (4), every layer of the prefabricated heat-insulating concrete wall body is composed of several trough-type or L-shaped prefabricated heat-insulating concrete wall body units (13). A concrete wall body vertical rib (12) is cast in situ between two adjacent prefabricated heat-insulating concrete wall body units (13) in same layer and connects them into integrity. The upper and lower ends of the rib (12) connect together with the beam of the floor, and the external side of the connecting beam (2) is covered with the heat-insulating material layer (4).
