[0003] Modular buildings are connected through connection boxes arranged thereon. In the prior art, the connection boxes of two modular buildings are mostly connected by bolts, but bolts are difficult to transmit the tension, pressure and shear force between the two modular buildings, resulting in poor stability of the connection between the modular buildings.

Its specification discloses that the box-type structural units are generally connected by bolts to achieve the connection between the upper, lower, left and right modules. During on-site assembly, the connection plate is first positioned and placed on the lower module, and then the positioning cone is installed in the corner hole on the lower module, and the bolts are tightened.

[0025] (III) Beneficial effects

During use, the resistance part can transmit the tension, pressure and shear force between the lower node box part and the upper node box part, thereby improving the stability between the lower node box part and the upper node box part;

[0028] 2. Through the high-strength non-shrinkage grouting, the upper node box and the lower node box are both poured with high-strength non-shrinkage grouting. The cooperation of the rib plate and the high-strength non-shrinkage grouting can improve the firmness and stability of the connection between the resistance plate and the lower node box and the upper node box;

[0029] 3. Through the first guide fixing mechanism and the second guide fixing mechanism, when the lower node box is hoisted on the top of the upper node box, the lower node box can be guided by the cooperation of the first guide fixing mechanism and the second guide fixing mechanism, so as to facilitate the alignment of the lower node box with the upper node box. After the hoisting is completed, the position of the lower node box can be fixed by the cooperation of the first guide fixing mechanism and the second guide fixing mechanism. Such a setting can ensure the stability of the position of the lower node box before the high-strength non-shrinkage grouting solidifies, thereby improving the functionality of the first guide fixing mechanism and the second guide fixing mechanism.

[0030] 4. Through the first guide fixing mechanism and the second guide fixing mechanism, when the first guide fixing mechanism and the second guide fixing mechanism cooperate to guide the lower node box body, the two limit plates are inclined and cooperate with the guide wheel to reduce friction, and facilitate the lower node box body to be guided under the limit of the guide fixing plate during the guide plate descending process. After the guiding is completed, the two limit plates can be rotated to the horizontal, and at this time, the limit plates can limit the guide plate and the guide fixing plate, thereby improving the functionality of the first guide fixing mechanism;

[0031] 5. By setting up the first guide fixing mechanism and the second guide fixing mechanism, during the guide plate descending process, the two guide fixing plates cooperate with each other to limit the guide plate. When the lower node box body contacts the middle connecting plate, the two guide fixing plates approach each other under the squeezing of the guide plates. After pulling the positioning plate downward, the positioning plate is rotated around the support rod, and then the positioning plate is inserted into the socket, which can realize the fixation between the first guide fixing mechanism and the second guide fixing mechanism, so that the first guide fixing mechanism and the second guide fixing mechanism cooperate to fix the lower node box body.
