In an embedded void formwork that is placed and fixed on the unsolidified surface of a concrete substrate as a lower layer for a PC board, etc., a molded product made entirely of iron or a non-foamed product made of synthetic resin. Consisting of a molded product, the frame body has a space and an integrally molded engaging part that is embedded in an unsolidified concrete substrate and connects and fixes the frame body to the substrate surface when the substrate hardens. An embedded void formwork for PC boards, etc., which is characterized by: 2. The engaging portion is configured of a plurality of protrusions that protrude from the lower part of the frame main body and are divided into approximately rectangular shapes by cuts formed parallel to the protruding direction. An embedded void formwork for a PC board, etc., as set forth in claim 1 of the above-mentioned utility model registration claim. 3. The embedded void formwork for a PC board, etc., according to claim 2 of the above-mentioned utility model registration claim, wherein the projecting piece is bendable. 4. The embedded void formwork for a PC board, etc. according to claim 2 of the above-mentioned utility model registration claim, wherein the projecting piece is twistable and bendable about a vertical axis. 5. Claim 1 of the above-mentioned utility model registration, in which the frame main body is formed in a rectangular shape and has ribs on its surface extending along the long axis direction or the short axis direction of the frame.
Embedded void formwork for PC boards, etc., as described in section. 6. The embedded void formwork for a PC board or the like according to claim 1 of the above-mentioned utility model registration claim, wherein the frame main body is formed in a rectangular shape and has an open edge that communicates with the space. 7. Claim 6 of the above-mentioned utility model registration claim, wherein the frame main body is formed by forming a partition in the space that extends in the longitudinal direction of the frame so that piping, cables, etc. can be passed inside from the edge. Embedded void formwork for PC boards, etc. 8. The embedded void formwork for a PC board or the like according to claim 6, wherein the frame main body is sealed by a closing means for closing the edge. 9 P as stated in Paragraph 1 of the above utility model registration claim, in which the concrete substrate has reinforcing bars erected thereon.
Embedded void formwork for C boards, etc.
