Background

Building Information Modeling (BIM) is receiving general attention from both internationals and internationals at home and abroad as a new concept and technology. BIM is a numerical representation of the physical and functional characteristics of a facility; information can be inserted, extracted, updated and modified in the BIM at different stages to support and reflect the cooperative work of the respective responsibilities. The advent of BIM is changing the way in which project participants collaborate, making the building more efficient and improving the overall quality of the building.

The fabricated building refers to a kind of building which is manufactured by a factory assembly line in a factory to manufacture all components required by a house, then transported to a construction site, and hoisted and spliced on the site. The prefabricated building is relatively wide in requirements on building environment due to convenience, high construction speed and wide application range in actual production and life. The fabricated building is more efficient in building assembly with the help of the BIM model.

The prefabricated building wall generally includes prefabricated wall panels and connectors for connecting the prefabricated wall panels, so that a plurality of prefabricated wall panels are fixed in a vertical state to support a roof.

But in actual assembly process, the connecting piece not only needs to be fixed prefabricated wallboard, still needs to adjust the angle between the prefabricated wallboard. Among the correlation technique, the staff relies on the intuition to adjust prefabricated wallboard angle, leads to adjacent prefabricated wallboard angle to be inaccurate enough easily, makes the installation on follow-up roof go wrong.

Through adopting above-mentioned technical scheme, the tip of two prefabricated wallboards is located the location intracavity, passes sliding hole, locating hole and threaded connection with the screw hole in proper order through positioning bolt for prefabricated wallboard is compressed tightly on the planking by the compact heap. When the prefabricated wall board is installed, the positioning bolt penetrates through the positioning hole and the pressing block does not press the prefabricated wall board on the outer board, so that the end part of the prefabricated wall board is limited between the inner board and the outer board, and the inner board, the outer board and the prefabricated wall body can keep an upright state due to the fact that the adjacent inner boards have certain included angles. Because of the positioning bolt external diameter is less than the internal diameter of locating hole, make prefabricated wallboard can take place to remove in the location intracavity for prefabricated wallboard can carry out the transition of angle, when prefabricated wallboard passes through the connecting piece and encloses to establish cyclic annularly, adjacent prefabricated wallboard rotates to the state of keeping away from each other, when making the end connection of last connecting piece and two prefabricated wallboards, the convenient entering of tip of prefabricated wallboard fixes a position the intracavity.

Finally, the staff screws up positioning bolt in the screwed hole, and the compact heap makes prefabricated wallboard and planking support tightly, prevents that the clearance between planking and the prefabricated wallboard is too big, leads to outdoor rainwater to get into indoorly. And the compact heap makes prefabricated wallboard and planking parallel, makes prefabricated wallboard be difficult for crooked to improve the accuracy of the angle of adjacent prefabricated wallboard, make later stage roof simple to operate.
