[0022] Example

[0023] Please see Figure 1-5 This utility model provides a temporary support device for concrete formwork in construction engineering, including a base 1, a support column 2 on the base 1, a lifting assembly inside the support column 2, the lifting assembly being connected to two support rods 3, the top ends of the two support rods 3 passing through the support column 2 and fixedly connected to a support plate 4, the support plate 4 being connected to the concrete formwork 5 via connectors. The lifting assembly is connected to a locking assembly, the locking assembly being housed in a locking box 6, the locking box 6 being mounted on the base 1.

[0024] The lifting assembly includes a one-way lead screw 7, to which a one-way lead screw assembly 8 is threadedly connected. The one-way lead screw assembly 8 is fixedly connected to the bottom of two support rods 3, and both ends of the one-way lead screw assembly 8 are sleeved on two U-shaped rods 9. Both U-shaped rods 9 are fixedly connected to the inner wall of the support column 2. The U-shaped rods 9 improve the movement stability of the one-way lead screw assembly 8.

[0025] A bevel gear 10 is fixedly connected to the lower part of the one-way lead screw 7. The bevel gear 10 meshes with the bevel gear 11. The bevel gear 11 is fixedly connected to the rotating shaft 12. A rotating sleeve 13 is fixedly sleeved on the outside of the rotating shaft 12. A rotating handle 14 is provided at the end of the rotating sleeve 13. Rotating the rotating handle 14 clockwise drives the one-way lead screw 7 to rotate through the transmission of the bevel gear 11 and the bevel gear 10, causing the one-way lead screw assembly 8 to move upward on the one-way lead screw 7, and driving the support plate 4 to move upward through the support rod 3. Conversely, rotating the rotating handle 14 counterclockwise causes the one-way lead screw assembly 8 to move downward on the one-way lead screw 7, and driving the support plate 4 to move downward through the support rod 3, thus realizing the support and disassembly of the support device.

[0026] The locking assembly includes a bidirectional lead screw 15, on which two symmetrically arranged bidirectional lead screw pairs 16 are threadedly connected. Two clamping blocks 17 are fixedly connected to the top ends of the two bidirectional lead screw pairs 16. The two clamping blocks 17 have facing arc-shaped openings with a plurality of evenly distributed clamping protrusions 18. The clamping protrusions 18 are semi-circular in structure to enhance the friction between the clamping blocks 17 and the rotating sleeve 13, thereby improving clamping stability. A guide rod 19 is also provided inside the locking box 6, and the upper parts of the two clamping blocks 17 are fitted onto the guide rod 19. The guide rod 19 serves an auxiliary function, improving the stability of the two clamping blocks 17 during movement.

[0027] One end of the bidirectional lead screw 15 is connected to the inner wall of the locking box 6 via a bearing, and the other end of the bidirectional lead screw 15 is fixedly connected to a crank handle 20. The crank handle 20 has a through hole through which an insertion rod 21 passes, and the bottom of the insertion rod 21 is inserted into the bottom hole of the base 1. By rotating the crank handle 20 clockwise, the bidirectional lead screw 15 is rotated, which in turn causes the two clamping blocks 17 to move towards each other, clamping the rotating sleeve 13. Conversely, by rotating the crank handle 20 counterclockwise, the bidirectional lead screw 15 is rotated, which in turn causes the two clamping blocks 17 to move away from each other, releasing the rotating sleeve 13.

[0028] The connector includes a connecting strip 22 and a connecting groove 23. The connecting groove 23 is formed on the top of the support plate 4, and the connecting strip 22 is fixedly connected to the bottom of the concrete formwork 5. The dimensions of the connecting strip 22 and the connecting groove 23 are compatible. In use, a through hole is made in the connecting strip 22, and the connecting strip 22 is nailed to the concrete formwork with screws. Then, the connecting strip 22 is inserted into the connecting groove 23. The plug-in structure improves the connection between the support plate 4 and the concrete formwork 5, and prevents relative displacement between the support plate 4 and the concrete formwork 5 during the support process, which would affect the support.

[0029] In practical use, first fix the connecting strip 22 below the concrete formwork 5, then insert the connecting strip 22 into the connecting groove 23, rotate the rotating handle 14, and drive the two support rods 3 upward through the one-way screw 7. The support plate 4 drives the concrete formwork 5 upward to support the concrete. After the concrete formwork 5 reaches the designated position, rotate the crank handle 20, and drive the two clamping blocks 17 to move towards each other through the two-way screw 15 until the crank handle 20 can no longer be cranked. At this time, the two clamping blocks 17 clamp the rotating sleeve 13 and cannot rotate it. The position of the crank handle 20 at this time is as follows: Figure 4 As shown, insert the rod 21 through the through hole on the crank handle 20 and into the bottom hole to complete the support.

[0030] Therefore, this utility model adopts the above-mentioned temporary support device for concrete formwork in construction engineering. By setting up a lifting component to adjust the support height of the support plate, it is convenient to support concrete formwork of different heights and improves adaptability. By setting up a connector to connect the support plate and the concrete formwork, it is possible to avoid the support device shifting due to external factors during the support process, thus affecting the support effect. By setting up a locking component, it is possible to prevent the lifting component from falling accidentally, thereby improving the stability of the support.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
