[0021] like Figure 1-4 As shown, the present invention discloses a reusable column foot hydraulic lifting roller and method for the module column foot position, which is used for the installation of prefabricated buildings. The column foot hydraulic lifting roller 1.3 includes a base 1, a hydraulic jack 2 and a column side sliding connector 3. The hydraulic jack 2 is installed between the base 1 and the column side sliding connector 3, and is used to lift and lower the column side sliding connector 3.

[0022] The base 1 is provided with a mounting groove 1.1, into which the hydraulic jack 2 is mounted, and a hydraulic pipe 2.1 of the hydraulic jack 2 passes through the groove wall, wherein the hydraulic jack 2 can select an ultra-thin hydraulic jack 2; a pair of ear plates 1.2 are formed under the base 1, and a roller 1.3 is installed between the two ear plates 1.2, and the roller 1.3 can select a resin roller 1.3, and a rail groove 1.4 is provided in the center of the roller 1.3 along its circumference, which cooperates with the ground rail 9 on the top beam 8, so that the roller 1.3 moves along the ground rail 9 to prevent the building module 14 from shifting during the insertion and sliding process.

[0023] The column side sliding connector 3 is matched with the base 1 to slide vertically. The column side sliding connector 3 includes a pair of side plates 3.1. A horizontal cross plate 3.2 is fixedly arranged between the side plates 3.1 in the horizontal direction, and a vertical plate 3.3 is fixedly arranged in the vertical direction. A reinforcing rib 3.4 is arranged between the vertical plate 3.3 and the horizontal cross plate 3.2 to transmit the gravity of the building module 14 transmitted from the column wall. The hydraulic jack 2 is supported on the horizontal cross plate 3.2 and can be lifted up and down under the action of the hydraulic jack 2. Bolt holes 5 are opened on the vertical plate 3.3 and the column 4. Three bolt holes 5 are arranged at vertical intervals. Nuts are fixedly arranged on the inner wall of the column 4, and the vertical plate 3.3 and the column 4 are fixed by bolts.

[0024] Two smooth bolts 6 are respectively provided on the two side walls of the base 1, and the two smooth bolts 6 are located at the same height. A vertical groove 7 is opened on the side plate 3.1, and the smooth bolts 6 are slidably set in the vertical groove 7. The double vertical groove 7 is set to prevent the column side sliding connector 3 from always flipping over during the jacking or transportation process of the building module 14.

[0025] The method of use includes the following steps: Step 1: Arrange the ground rail 9 at the center of the upper flange of the top beam 8 of the modular building, install the inner partition 10 on the inner side of the upper end of the column 4, and set two introduction ribs 11 on the inner partition 10 for passing the roller 1.3 as the sliding introduction path of the superstructure module 14.

[0026] Step 2: transport the building module 14 and place it on the guide rail frame 12 on the ground, align the guide rail frame 12 with the lifting bracket 13, and install the hydraulic lifting roller 1.3 on the lower end side of the column 4.

[0027] Step 3: Raise the hydraulic jack 2 by about 30 mm, push the building module 14 from the guide rail frame 12 into the lifting bracket 13, and lift the lifting bracket 13 to the installation position. During the lifting process, use wind-resistant cables to resist the wind load during the lifting process.

[0028] Step 4: Use the servo motor traction module to slide the building module 14 along the ground rail 9 into the installation position.

[0029] Step 5: Lower the height of the column 4 by the hydraulic jack 2, insert the conical pin into the socket at the top of the column 4, and remove the hydraulic lifting roller 1.3 device.

[0030] The embodiments described above are merely descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
