The specific implementation mode is as follows:

the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, the tongue-locking type self-locking connection node between the upper module unit and the lower module unit of the modular building of the present embodiment is used for self-locking connection between an upper module column 1 and a lower module column 8, and includes a pair of upper connecting members 2, two springs 3, four locking tongues 4, a side sealing plate 5, and a pair of slideway slot plates 6. Go up connecting piece 2 and fix on 1 inner wall of last module post through welding or other modes, go up connecting piece 2 and set up in pairs, every goes up connecting piece 2 and is the flute profile section, and 2 lateral walls of every goes up connecting piece are opened and are had two upper and lower rectangle holes, and the same 4 head cross sections of spring bolt of size make 4 heads of spring bolt just pass. Slide frid 6 is fixed on module post roof 7 down through welding or other modes, and slide frid 6 sets up in pairs, and every slide frid 6 is E shape cross-section, and two slide frids 6 enclose into two upper and lower hollow portions after placing relatively to form two upper and lower slide grooves, the same spring bolt afterbody cross section of size of every hollow portion makes spring bolt 4 can be at the slide inslot lateral shifting that two slide frids 6 enclose. The two springs 3 are respectively arranged in two slide way grooves surrounded by the two slide way groove plates 6 and can be fixed with the tail part of the bolt 4. Side seal board 5 sets up to two, for the rectangle sheet metal, opens and has two rectangle holes, and rectangle hole size is the same with 2 lateral wall rectangle holes of last connecting piece, makes 4 heads of spring bolt just pass through, and the afterbody can not pass through.
