The traditional supporting structure is reinforced with steel pipes. Since the height of the formwork cannot be unified, it is impossible to produce matching steel pipes for use. Usually, inclined steel pipes are used for support. This type of support structure has insufficient stability and low seismic reinforcement performance. Utility Model Content

[0027] The support structure is used to support the support bottom plate 1 and the support top plate 2. At the same time, the threaded support rod 5 can move up and down inside the rotating threaded sleeve 4 to adjust the distance between the support top plate 2 and the support bottom plate 1, so as to facilitate the support of formworks of different heights. At the same time, an adjustment component 9 is arranged on the outer side of the threaded support rod 5 to support the support plates 8 around the support top plate 2, thereby increasing the support area, ensuring the stability of the support, and improving the seismic reinforcement capability.

[0028] The driving assembly 7 includes a worm wheel 71 fixed to the outside of the threaded sleeve 4. The inner cavity of the fixed cylinder 3 is rotatably connected to a worm 72 through a bearing. The worm 72 meshes with the opposite side of the worm wheel 71. One end of the worm 72 passes through the outside of the fixed cylinder 3 and is provided with a socket 73. Through the cooperation of the socket 73, the worm 72 is driven by an external turning handle, and then the worm 72 drives the worm wheel 71 to rotate, so that the threaded sleeve 4 and the worm wheel 71 rotate synchronously. The threaded connection relationship between the threaded support rod 5 and the threaded sleeve 4 is utilized to ensure that the threaded support rod 5 moves up and down under the condition of a limited position structure.

Through the setting of the connecting hole 18, multiple groups of devices can be conveniently connected through connecting rods to form a larger structure support device, thereby ensuring support for large-area aluminum alloy templates.

[0035] When in use, the mounting bolts are removed and the external turning handle is inserted into the socket 73 to connect with the worm gear 72, thereby driving the worm gear 72 to rotate and drive the worm wheel 71, and the worm wheel 71 drives the threaded sleeve 4 to rotate. The threaded support rod 5 moves upward in the fixed cylinder 3 under the restriction of the limit block 15, and then the positioning rod 12 and the positioning hole 11 are used to support the support top plate 2. At the same time, the turntable 10 is rotated to make the turntable 10 move up on the threaded support rod 5, and the support of the movable plate 92 by the rotating cylinder 91 is used to unfold the support plate 8, which is located around the support top plate 2 and flush with the support top plate 2, so that the support top plate 2 and the support plate 8 support the large-area template and ensure the stability of the template. The limiting bolts 93 are rotated to limit and fix the turntable 10 to prevent the turntable 10 from rotating again and affecting the stability of the support plate 8 structure.
