It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] Embodiment 1

[0027] Combination Figures 1 to 4 As shown, this embodiment discloses a small component foundation rapid formwork device including a plurality of adjustable combined steel molds 1 and socket-type connectors 2 which are alternately connected in sequence and arranged in a ring shape; wherein each adjustable combined steel mold 1 includes a first steel mold 3 and a second steel mold 4, one side of the first steel mold 3 and the second steel mold 4 is formed with a first connecting head 5, and the other side of the first steel mold 3 and the second steel mold 4 is formed with a first connecting groove 6; the first connecting head 5 of the second steel mold 4 is operably slidably arranged in the first connecting groove 6 of the first steel mold 3.

[0028] Furthermore, the socket-and-spigot connector 2 of the present embodiment is cylindrical, and a second connector 7 and a second connector groove 8 are formed on the cylindrical surface of the socket-and-spigot connector 2; the second connector 7 formed on the cylindrical surface of the socket-and-spigot connector 2 can be operably slidably disposed in the first connector groove 6 of the adjacent second steel mold 4, and the second connector groove 8 formed on the cylindrical surface of the socket-and-spigot connector 2 can be operably slidably connected to the first connector 5 of the adjacent first steel mold 3. It is worth noting that the cross-sectional shapes of the first connector 5 and the first connector groove 6 are both fan-shaped, and the end faces formed by the two radii of the fan-shaped can achieve the limiting effect to prevent the first connector 5 and the first connector groove 6 from separating. The second connector 7 and the second connector groove 8 also adopt the same fan-shaped cross-section. Of course, in other embodiments, the cross-sectional shape can be selected according to actual needs.

[0029] Furthermore, in this embodiment, scale lines 9 are formed on the first steel mold 3 and the second steel mold 4. When the first steel mold 3 and the second steel mold 4 are connected, the scale lines 9 can help determine whether they are aligned.

[0030] Furthermore, in this embodiment, fastening bolts 10 are installed on the first steel mold 3 and the second steel mold 4, and the fastening bolts 10 vertically penetrate the corresponding first steel mold 3 and the second steel mold 4. After the two steel molds are assembled, they need to be installed on the wall, and at this time, the fastening bolts 10 can be turned to complete the installation of the steel molds.

[0031] Furthermore, the outer surfaces of the first steel mold 3 and the second steel mold 4 of this embodiment are formed with sawtooth protrusions 11. The sawtooth protrusions 11 are arranged horizontally and arranged in sequence along the longitudinal direction. The provided sawtooth outer surface can enhance the bite ability of the new and old concrete bonding surfaces.

[0032] Embodiment 2

[0033] As another embodiment of the present utility model, Figure 5 and Figure 6 As shown, different from the first embodiment, the upper and lower ends of the first steel mold 3 and the second steel mold 4 of this embodiment are fixedly provided with connecting rings 12, and the two connecting rings 12 on the first steel mold 3 are coaxially arranged; the two connecting rings 12 on the second steel mold 4 are coaxially arranged. In addition, a threaded hole 13 is formed at the upper end of the socket-type connector 2, and a threaded rod 14 extends from the lower end of the socket-type connector 2. When the foundation depth is large, one layer of steel mold cannot completely cover the foundation depth, so multiple layers of steel molds are required. The connecting ring 12 of this embodiment can quickly complete the splicing of the upper and lower steel molds, and the threaded hole 13 formed at the upper end of the socket-type connector 2 and the threaded rod 14 extending from the lower end can also be quickly spliced.
