This embodiment provides a reinforced support structure for construction engineering, including a rectangular base plate 1, and a plurality of first through holes 1-1 are opened at the edge of the base plate 1 for installing bolts or driving steel bars, etc. , and fix the base plate 1 on the ground.

A hollow cuboid mounting seat 2 is installed in the middle of the upper bottom surface of the base plate 1 by bolts, and a jacking mechanism is installed inside. A lower support column 3 with a rectangular cross section and a hollow interior is fixedly installed on the top of the mounting seat 2, and an upper support column 4 with a rectangular cross section is also sleeved in the lower support column 3, and can be moved along the lower support column 3 under the action of the jacking mechanism. Put down the support column 3 for free lifting. The lower support column 3 only plays a guiding role and does not play a load-bearing role.

Specifically, the inner upper half of the lower support column 3 is an upper column hole 3-1 with a rectangular cross-section, and a pair of opposite sides of the upper column hole 3-1 is provided with a rectangular sliding groove 3- 3. The length of the chute 3-3 is equal to the depth of the upper column hole 3-1; the lower half section inside the lower support column 3 is the lower column hole 3-2 whose cross section is circular and smaller than the cross section of the upper column hole 3-1 , the lower column hole 3-2 communicates with the upper column hole 3-1, so that the lower support column 3 becomes a hollow structure. The jacking mechanism is connected to the upper support column 4 through the lower column hole 3-2, and pushes the upper support column 4 to lift. The upper support column 4 is fixedly installed with a rib slide block 4-1 matched with the chute 3-3, which can effectively prevent the upper support column 4 from uncontrollably shifting during the up and down sliding process. Of course, the upper column hole 3-1 may also pass through the entire lower support column 3, that is, there is only one upper column hole 3-1 in the lower support column 3. As shown in FIG.

The jacking mechanism includes a lead screw 17, the lower part of which is rotatably connected with the connecting seat 1-2 fixed on the bottom plate, and the upper part passes through the lower column hole 3-2 and is threaded with the upper supporting column 4, that is, the upper supporting column 4 There is a threaded hole at the bottom of the threaded rod, and the lead screw 17 is threadedly matched with the threaded hole; the lower column hole 3-2 can prevent the lead screw 17 from shaking during the rotation. A gear 16 is fixedly mounted on the lower part of the lead screw 17 . The gear 16 is located above the connecting seat 1-2 and meshes with the worm 15 installed in the mounting seat 2 horizontally. The first end of the worm 15 is rotatably connected to the inner wall of the mounting seat 2 , and the second end penetrates the mounting seat 2 and is connected to the drive assembly. The lead screw 17 is a self-lockable lead screw such as a trapezoidal lead screw.

The drive assembly includes a gate-shaped bracket 12 fixedly mounted on the base plate 1 by bolts, and a rotating shaft 11 vertically mounted on the bracket 12 . The rotating shaft 11 is rotatable, with a hand wheel 10 fixedly mounted on the top and a first bevel gear 13 fixedly mounted on the bottom, which meshes with the second bevel gear 14 fixedly mounted on the second end of the worm 15 . Of course, the drive assembly can also be replaced by other components that can drive the worm 15 to rotate, such as a motor.

The top of the upper support column 4 is fixed and installed with the support plate 7 , and the bottom surface area of the support plate 7 is larger than the bottom surface area of the upper support column 4 . A threaded telescopic rod 5 is hinged between the support plate 7 and the upper support column 4 . Specifically, a pair of second hinge ears 9 are installed on the two sides of the upper support column 4 without the rib plate sliders 4-1 installed, and a connecting plate 6 is fixedly installed on the bottoms of both ends of the support plate 7 to connect The bottom of the plate 6 is installed with a first hinge ear 8 corresponding to the second hinge ear 9, and the two ends of the threaded telescopic rod 5 are hinged to the first hinge ear 8 and the second hinge ear 9 respectively, forming a stable triangular support structure, At the same time, the threaded telescopic rod 5 can be adapted to support plates 7 of different sizes. The threaded telescopic rod 5 can also be transferred between the side surface of the upper support column 4 provided with the rib plate slider 4-1 and the support plate 7.

The support plate 7 is provided with a plurality of oval expansion holes 7-1, which can be used to install other supporting components.

The jacking mechanism in this embodiment may also be a hydraulic cylinder or an air cylinder, and the corresponding driving component is a hydraulic pump station or an air pump.
