[0002] The construction of prefabricated buildings has the advantages of convenient construction, short construction period, little pollution to the surrounding environment, easy factory production of building components, batch centralized production and easy assurance of component quality. Among them, prefabricated steel structure module box buildings are widely used due to the flexibility and aesthetics of module layout.

[0003] The steel structure module box building is transported to the installation site by large lifting equipment, connected through the corner boxes set at the corners of the module boxes and the bolt holes and fixing bolts set on the corner boxes, and multiple module boxes are connected into an integrated combination according to specific spatial positions and spatial sequences.

[0004] However, during the actual installation process, it is necessary to manually observe and adjust the position of the module box so that the module box falls to the installation position. The lifting accuracy of this method is not high and the error is large. After the module box is in place, the position deviation of the module box is often too large, resulting in a large misalignment of the bolt holes on the corner boxes of adjacent boxes that should correspond to each other, and the bolts cannot be screwed in to connect and fix. The position of the module box needs to be manually adjusted again, reducing construction efficiency. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the defects in the prior art that the module box position is prone to deviation, and the position of the module box needs to be manually adjusted again, which reduces the construction efficiency, thereby providing an assembled building box connection structure.

[0006] In order to solve the above technical problems, the utility model provides an assembled building box connection structure, comprising: a lower box, wherein the top corner position of the lower box has an upper corner box;

[0010] A fastener vertically passes through the lower corner piece box, the connecting plate and the upper corner piece box from one side, and two ends of the fastener are respectively fastened to the lower corner piece box and the upper corner piece box.

[0011] Optionally, the positioning member is a cone.

[0012] Optionally, a threaded rod extending downward is provided at the bottom of the cone, and one end of the threaded rod passes through the upper corner piece box and is connected to a first nut on the inner side of the upper corner piece box.

[0014] Optionally, the cone and the threaded rod are integrally formed.

[0015] Optionally, the diameter of the threaded rod is smaller than the diameter of the cone.

[0016] Optionally, one end of the connecting plate extends out of the upper corner box and is fixedly connected to the main building.

[0017] Optionally, the connecting plate is an integral structure continuously arranged along the length direction.

[0018] Optionally, the fastener is a tension bolt, and both ends of the tension bolt are connected to the upper corner piece box and the lower corner piece box respectively through a second nut.

[0019] Optionally, it also includes: a gasket, which is respectively arranged between one of the second nut and the upper corner piece box and between another of the second nut and the lower corner piece box.
