HEAT INSULATING PANEL CONCURRENTLY USED AS MOLD FORM

摘要

A heat insulating panel concurrently used as a mold form, comprising a panel body (1) and a T-shaped bar (20) fitted to the upper surface thereof integrally with each other. An upper surface vertical slit (10) is formed in the upper surface of the panel body (1) through its overall length, and a plurality of locking projected bars (11) are integrally and projectedly fitted in the slit at intervals in the longitudinal direction. The T-shaped bar (20) comprises a connection portion (21) and a pair of insertion portions (22) and (23). The lower insertion portion (23) is inserted into the upper surface vertical slit (10) of the panel body (1), and locked by the projected bars (11) to prevent the lower insertion portion from being coming out. Thus, the heat insulating panel concurrently used as the mold form having the pane body and the T-shaped bar can be rapidly and easily manufactured and its production cost can be remarkably reduced.
