Detailed ways

Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the utility model can have various changes in different embodiments, all of which do not depart from the scope of the utility model, and the description and drawings therein are used for illustration in essence, not for reference. To limit the utility model.

As shown in Figure 1, the connection mode of the building units of the modular building includes two ways of up and down series connection and left and right parallel connection, among which 101 and 102, 103 and 104 are all connected in parallel, and between 101 and 104, between 102 and 103 All are connected in series. Each building unit includes an upper beam 11, a lower beam 12 (the upper beam 11 and the lower beam 12 are beam frames), corner columns 13 and a shell 14, the upper beam 11 is usually four end-to-end beam columns, and the lower beam 12 Usually, it is also four beams connected end to end, and the plane where the upper beam 11 is located is parallel to the plane of the lower beam 12 . The corner posts 13 are hollow and are vertically arranged edges, located at four corners, connecting with the upper beam 11 and the lower beam 12 up and down respectively.

As shown in FIG. 3 , the upper part of the corner post 13 is provided with a top plate 131 , and the lower part is provided with a bottom plate 132 (both the top plate 131 and the bottom plate 132 are end plates). The above-mentioned connection method is usually completed by welding. Both the top plate 131 and the bottom plate 132 of the corner post 13 are processed with first connecting holes 16 , the first connecting holes 16 on the top plate 131 and the bottom plate 132 have the same shape and size, and their positions correspond to each other. First mounting holes 15 are processed on the upper beam 11 and the lower beam 12 .

Multiple building units are connected through a quick-connect structure, which includes a connecting plate 2, bolts 4, and nuts 5 (please refer to Figure 5). The connecting plate 2 is pressed between the corner columns 13 of the connected building units. The structure of the connecting plate 2 is shown in FIG. . The boss 3 is inserted into the first connection hole 16 when the building unit is assembled, so as to bear a certain bending moment. Both ends of the boss 3 are provided with guide surfaces 31, which are sloped or arc-shaped, so as to play a role of positioning and guiding when the building units are docked. The boss 3 can be integrally formed with the connecting plate 2 by casting, or the boss 3 itself is an independent part, that is, the boss 3 is a bump protruding from the connecting plate on both sides. fixed by welding.

When the boss 3 is set as a separate component, the connecting plate 2 is provided with one to four second connecting holes 21, and the number of the second connecting holes 21 is equal to the number of the boss 3, which is exactly the same as that required by the connecting plate 2. The number of connected parallel building units is the same, the second connecting hole 21 corresponds to the first connecting hole 16 , and the second connecting hole 21 and the first connecting hole 16 have the same shape and size, and both are long holes. In addition, the transverse spacing between the two bosses 3 is equal to the transverse spacing between the two first connection holes 16 on the two connected building units, and the longitudinal distance between the two bosses 3 is equal to the two first connection holes on the two connected building units. The longitudinal spacing between 16 is equal to ensure the assembly relationship.

Two or more second mounting holes 22 (usually 2, left and right symmetrically processed to achieve fast connection) are also processed on the connecting plate 2 , and the second mounting holes 22 correspond to the first mounting holes 15 . The second mounting hole 22 can be a plain hole or a threaded hole.

The stud 4 passes through the first installation hole 15 and the second installation hole 22 and is fastened by the nut 5 . The installation process is shown in Figure 3, (when the boss 3 is a separate component), first connect the second connection hole 21 on the connection plate 2 to the first connection hole 16 of the lower building unit, and insert the protrusion 3 into the second connection hole 21, and insert the exposed lower part into the first connection hole 16, the exposed end of the upper part also has a guide surface 31, and then weld and fix it on the connecting plate 2, and hoist the superstructure unit to the top of the substructure, Under the guidance of the guide surface 31, it is superimposed on the lower construction unit, and then the bolt 4 is used to pass through the first installation hole 15 of the upper construction unit, the second installation hole 22 on the connecting plate 2 and the first installation of the lower construction unit. The hole 15 is fitted with the nut 4 and tightened, and finally the connection is completed. This process is fast and simple, and the positioning is accurate. The structure after installation is shown in Figure 4. In order to strengthen the connection strength, flat washers, spring washers and double nut structures can also be used.

As shown in Figure 4 and Figure 5, in the actual building unit assembly process, except that the corner column 13 part is connected through the above-mentioned quick-connect structure, the upper beam 11 and the lower beam 12 of the building units connected in series up and down are usually connected by bolts 4 The nuts 5 are connected and fixed through two corresponding first installation holes 15, so that the upper beam and the lower beam between the upper and lower building units are connected.

In addition, as shown in Figure 5, in order to further strengthen the connection strength, the corner columns 13 of the left and right parallel building units can also be connected and fixed through the third installation hole (not shown in the figure) through the bolts 4 and nuts 5, so that Can strengthen the parallel connection strength. At this time, the corner post has a "concave" shape, and a third installation hole is processed on the outer surface of the corner post.
