[0002] Modular construction is an important trend in the development of the construction industry in recent years. As one of the most prefabricated building forms in prefabricated buildings, modular construction has gradually developed into a hot spot in my country's construction industrialization with its unique advantages in construction, management and green environmental protection. Modular structural buildings have the advantages of high degree of integration, fast and efficient assembly, etc. The connection nodes between modules have a significant impact on the overall performance of the structure, so the design of the nodes is crucial. The development history of modular building structures at home and abroad has studied the structural forms of connection nodes from the component assembly level, modular structure level and modular building level. At present, various forms of modular building structure connection nodes have appeared at home and abroad and have been applied in actual projects. Summary of the invention

[0008] Preferably, the shape of the upper surface of the force applying handle is arc-shaped, and the arc of the upper surface of the force applying handle is between one hundred and fifty degrees and one hundred and eighty degrees.

[0009] Another technical problem to be solved by the present invention is to provide a method for preparing a modular building prestressed mortise and tenon joint structure, comprising the following steps:

[0010] S1. Mechanically manufacture the tenon and the mortise, and open mechanical processing holes on the tenon and the mortise surface according to appropriate sizes;

[0011] S2. Fix the mortise to the end corner of the unit module by bolts or welding, and set eight mortises for each unit module;
