[0029] Positioning holes are arranged at four corners of the top plate, and matched holes are arranged at the four corners of the top plate; the number of small-diameter threaded sleeves, large-diameter bidirectional threaded sleeves, mounting bolts and positioning bolts is four.

[0038] The modular house positioning and leveling structure solves the positioning and leveling and locking of the upper and lower layers of modular houses, and the operation method is as follows:
[0039] (1) Four TR30 / L=200 bolts are screwed into the TR30 bidirectional threaded sleeves of the four matched holes of the bottom plate of the upper layer of modular houses and are exposed downward by 50mm in length, the upper layer of modular houses is lifted, and is slowly moved to the top of the lower layer of modular houses.
[0040] (2) When the distance from the top of the lower layer of modular houses is 20cm, the TR30 bolts exposed on the bottom plate of the upper layer of modular houses are matched and positioned with the positioning holes of the lower layer of modular houses, when the exposed part of the TR30 bolts is hindered by the reverse circular truncated position of the positioning holes and cannot be moved, it is indicated that the hole position is successfully positioned.
[0041] (3) Put the measuring tool such as laser instrument on the bottom plate of the upper layer module room, select the center point on the bottom plate, measure the original elevation of the four corner matched holes in the module room, obtain the required elevation value through calculation, and then adjust the TR30 bolt in the matched hole using the hexagonal wrench, measure once every two turns of the bolt, and then place the gasket in the gap at the four corners of the upper and lower module rooms according to the size after single measurement, and sequentially cycle the above actions until the elevations of the four corners of the bottom plate of the upper module room are consistent, indicating that the leveling of the upper module room is completed.
[0042] (4) Remove the TR30 bolt, replace it with an 8.8 grade M20 bolt, and add appropriate bolt gaskets, screw the M20 threaded sleeve in the positioning hole from the matched hole down until it is completely tightened, and if there is a gap between the flange nut and the bottom plate, the 8.8 grade M20 bolt needs to be removed and additional bolt gaskets are added, and then the M20 threaded sleeve is tightened again. The flange nut should be in contact with the bottom plate to represent that the upper and lower module rooms have been locked and connected.
[0043] (5) After the turnover is completed, the gap between the two layers is filled with a filling layer, and UHPC ultra-high performance concrete is poured into the interior using a sprinkler device. When the grouting material overflows outward from one side, it is sealed with a rubber strip after being polished, until all the edges are sealed. After 24 hours, the rubber strip is removed, and then water is sprayed for two days to ensure that the strength meets the requirements. Thus, the upper and lower layered module room structure is converted into a monolithic structure.
