Detailed Implementation

[0018] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0019] like Figure 1 and Figure 2 As shown, the construction lifting support frame of this scheme includes a base 1. The bottom of the base 1 is provided with several height-adjustable legs 17 so that when supporting uneven ground, the base 1 can be adjusted to a horizontal support state by rotating the height-adjustable legs 17.

[0020] The base 1 is fixedly connected to the bottom of the column 2 by fixing bolts. A strip-shaped mounting groove 6 is provided vertically on the column 2. A drive screw 7 is installed in the strip-shaped mounting groove 6. The lower end of the drive screw 7 is connected to a drive motor 8. A drive block 9 is fitted onto the drive screw 7, and the drive block 9 slides in contact with the strip-shaped mounting groove 6. Several parallel top support rods 10 are provided on the drive block 9. The top support rods 10 pass through the upper end of the column 2 and connect to a top support column 11. The top of the top support column 11 is hinged around its perimeter. Four support crossbars 3 are connected, which can be unfolded in a cross shape on the horizontal plane, and the rotation surfaces of the hinge joints of the four support crossbars 3 are all vertical surfaces; four vertical sliding grooves 12 are respectively provided around the top support column 11, and the limiting sliders 13 slide in the vertical sliding grooves 12. The middle part of the support crossbar 3 is hinged to one end of the diagonal support rod 14, and the other end of the diagonal support rod 14 is hinged to the limiting slider 13; when the four support crossbars 3 are unfolded in a cross shape on the horizontal plane, the limiting slider 13 abuts against the bottom of the vertical sliding groove 12.

[0021] A telescopic rod 4 is movably embedded in the support crossbar 3. The outer end of the support crossbar 3 is fitted with a limit bolt 16, which abuts against the side wall of the telescopic rod 4. A connecting plate 5 is provided on the outer end of the telescopic rod 4. When the telescopic rod 4 is in a horizontal state, the connecting plate 5 protrudes vertically downward. Bolt holes 18 are provided on the connecting plate 5. A triangular stiffening rib 15 is provided between the connecting plate 5 and the telescopic rod 4.

[0022] This design uses a drive motor 8 to rotate a drive screw 7, thereby adjusting the height of the drive block 9, top support rod 10, and top support column 11 to accommodate different heights of building structures. The four support crossbars 3 at the top of the top support column 11 can be spread out in a cross shape on the horizontal plane and are stably supported by diagonal braces 14. The support range of the support crossbars 3 can be extended by telescopic rods 4. At the same time, the telescopic rods 4 between the two support frames can be fastened by the cooperation of the connecting plate 5 and bolts, and the triangular stiffening ribs 15 make the joint less prone to bending.

[0023] This solution allows for the placement of multiple support frames, which are connected via connecting plates 5, thereby forming a relatively stable support grid structure on the horizontal plane with several support crossbars 3 and telescopic rods 4. Its operation is convenient, reducing manpower and material consumption and accelerating project progress. Furthermore, during transportation, the base 1 and column 2 of this solution are detachable, and the four support crossbars 3 can be rotated and retracted until they are parallel to the column 2, thus reducing radial space occupation and facilitating the stacking and bulk transportation of the support frames.
