The invention discloses a heat preservation plate and
steel frame combined type outer wall formwork, and relates to the technical field of building formworks, the outer wall formwork is composed of a
steel frame and a heat preservation plate, a longitudinal connecting
assembly is installed on the
steel frame, a transverse anti-
instability unit is arranged in the longitudinal connecting
assembly, and the heat preservation plate is matched and fixed with the longitudinal connecting
assembly through a positioning connecting rod. Under the action of
self weight, the insulation board can be automatically locked and effectively connected with a wall body. The longitudinal connecting assembly is provided with a through hole, the
diameter of the through hole is larger than that of the positioning connecting rod, and therefore automatic positioning and fixing of the insulation board are achieved. The design of an anti-
instability unit, a guide sliding groove, a spring assembly and the like ensures that the insulation board is stable and does not fall off. The protection shell is matched with the connecting support, so that the heat preservation plate is
safer in the installation process, automatic separation is achieved after concrete pouring, and the disassembly process is simplified. The device has the advantages of being simple in structure, convenient to install, stable and reliable, the construction efficiency can be remarkably improved, and manual operation is reduced.
