[0003] When carrying out cast-in-place construction, a support device is also required to support the formwork to ensure the smooth progress of cast-in-place construction. After retrieval and combined with actual cast-in-place construction experience, the common formwork support devices on the market still have some defects and deficiencies in actual use: Since the building floor heights are different, the heights of cast-in-place mezzanines are also inconsistent. Therefore, the support device is required to have strong height flexibility. However, the height adjustment of the existing support device is relatively complex and not easy to operate. Moreover, the support range of the device is small, and it is not easy to provide a larger area of support for the formwork. Therefore, it is urgent to improve the existing formwork support device for cast-in-place construction and provide a formwork support device for cast-in-place construction.

[0025] As Figures 1-5 shown, the cast-in-place construction formwork support device of the present utility model includes a base plate 1, a column 2 is fixedly connected above the base plate 1, an adjusting assembly 3 is fixedly provided in front of the top of the column 2, a movable column 4 is slidably connected inside the column 2, a ratchet part 5 is provided on the outer wall of the middle front end of the movable column 4, a support rod 6 is slidably connected inside the movable column 4, a support spring 7 is fixedly connected between the inner bottom of the movable column 4 and the bottom of the support rod 6, the top end of the support rod 6 is fixedly connected with a first top plate 8, and multiple groups of auxiliary support assemblies 9 are installed outside the first top plate 8.
[0026] On the basis of the above structure, the adjusting assembly 3 includes a connection box 31, a cross shaft 32, a worm gear 33, a gear 34 and a worm 35. The connection box 31 is fixedly connected to the outer wall of the front end of the top of the column 2. The connection box 31 and the column 2 are internally connected and communicated. A cross shaft 32 is installed by bearings inside the connection box 31. A worm gear 33 and a gear 34 are fixedly sleeved outside the cross shaft 32. The gear 34 is located on the right side of the worm gear 33. A worm 35 is meshed and connected in front of the worm gear 33. The worm 35 is connected to the connection box 31 by bearings.
[0027] On the basis of the above structure, the gear 34 is meshed and connected with the ratchet part 5, and the movable column 4 forms a lifting mechanism inside the column 2 through the gear 34.
[0028] In this embodiment, by manually rotating the worm 35, the worm wheel 33 is controlled to drive the horizontal shaft 32 and the gear 34 to rotate, so that the movable column 4 with a toothed portion 5 provided on the outer wall of the middle part of the front end, the support rod 6, the first top plate 8 and multiple groups of auxiliary support components 9 can be synchronously lifted, facilitating the quick adjustment of the height of the support device.
[0029] On the basis of the above structure, a positioning bolt 36 is threadedly connected to the outer wall of the front end of the top of the connection box 31, and the rear end of the positioning bolt 36 abuts against the top of the worm 35.
[0030] In this embodiment, by providing the positioning bolt 36, it is convenient to abut and position the worm 35, improving the state stability of the support device during the formwork support process.
[0031] On the basis of the above structure, multiple groups of auxiliary support components 9 are annularly distributed around the first top plate 8, and multiple groups of auxiliary support components 9 are interlocked with each other.
[0032] On the basis of the above structure, the auxiliary support component 9 includes a second top plate 91 and a support rod 92. The second top plate 91 is rotatably installed on the outside of the first top plate 8. The bottom end surface of the second top plate 91 is hinged with the support rod 92, and the end of the support rod 92 away from the second top plate 91 is hinged to the outer wall of the top of the movable column 4.
[0033] In this embodiment, when the movable column 4 moves upward relative to the support rod 6, the support rod 92 can be used to push the second top plate 91 to rotate to a horizontal state and fit with the construction formwork. By using the multiple unfolded second top plates 91, they can cooperate with the first top plate 8 to provide a larger area of support for the formwork, and the support effect is better.
[0034] The working principle of the present utility model is as follows:
[0035] During use, first place the support device on the indoor ground of the building and make the device located below the formwork to be supported. Subsequently, the worm 35 can be manually rotated to control the worm wheel 33 to drive the horizontal shaft 32 and the gear 34 to rotate synchronously, so as to control the movable column 4 with a toothed portion 5 provided on the outer wall of the middle part of the front end to drive the support rod 6, the first top plate 8 and multiple groups of auxiliary support components 9 to be synchronously lifted, facilitating the quick adjustment of the height of the support device and being convenient for use in the formwork support of cast-in-place floor slabs with different heights;
[0036] As the movable column 4 rises, the first top plate 8 first abuts against the bottom end surface of the construction formwork and remains stationary. Subsequently, the movable column 4 is continuously controlled to move upward until the top of the movable column 4 abuts against the bottom end surface of the first top plate 8. During this process, when the movable column 4 moves upward relative to the support rod 6, the support rod 92 can be used to push the vertically arranged second top plate 91 to rotate to a horizontal state and fit with the bottom end surface of the construction formwork. The multiple unfolded second top plates 91 can cooperate with the first top plate 8 to provide a larger supporting area for the construction formwork, and the supporting effect is better. When the device is idle, the vertically arranged second top plate 91 can reduce the volume of the device, facilitating the transfer of the device;
[0037] It should be particularly noted that a support spring 7 is fixedly arranged between the bottom of the support rod 6 and the inner bottom of the movable column 4, facilitating the reset of the device after use. Moreover, when the height of the support device is adjusted and the device is in use, the positioning bolt 36 can also be tightened to achieve the abutting positioning of the worm 35, ensuring the height and stability of the support device.
[0038] The above are only the preferred specific embodiments of the present invention and are not intended to limit the protection scope of the present invention; any equivalent changes, modifications, substitutions, and variations made by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning, or limited experiments shall fall within the protection scope determined by the claims.
