In such an Alfom, a gap maintaining device that maintains the gap between a pair of panels constant until curing is completed is introduced.

 Conventional spacing maintaining devices have coupling holes at both ends and are coupled to a pair of alforms so that the coupling holes are exposed to the outside of the alform, and a separate fastening pin or the like is inserted into the coupling hole to secure the bonding force with the alform. And when the concrete is cured, the fastening pin is removed, and then the alfom is dismantled to complete the concrete structure.

At this time, the gap maintaining device is largely composed of a span portion located in the space between the alforms and a point portion that is in contact with and coupled to the alform, and when concrete is poured, a load is intensively applied to the point portion.

However, the conventional gap maintaining apparatus has no problem that no reinforcing means are applied to the point portion, and thus it must be made thicker than necessary.
