The inner sides of the upper folded top piece and the lower folded bottom piece are respectively connected to the upper end and the lower end of the second connecting piece; at least one interlocking piece group is integrally bent to form an angle iron and is provided on the inner side of the first connecting piece and the second connecting piece of the corner connecting frame. The interlocking piece group includes a first interlocking piece and a second interlocking piece and protrudes from the first connecting piece and the second connecting piece of the corner connecting frame. The first interlocking piece is provided with at least one first connecting through hole, and the second interlocking piece is provided with at least one second connecting through hole.

2. The L-shaped steel connecting plate module as described in claim 1, wherein, The first connecting hole and the second connecting hole of the first insert and the second insert are circular or elliptical in shape.

3. The L-shaped steel connecting plate module as described in claim 1, wherein, The angle iron formed by the first and second joint pieces of the corner joint frame has an included angle.

4. The L-shaped steel connecting plate module as described in claim 1, wherein, The first joint piece of the corner joint frame is the same width as the second joint piece.

5. The L-shaped steel connecting plate module as described in claim 3, wherein, The angle between the first joint piece and the second joint piece of the corner joint frame forming the angle iron is less than or equal to ninety degrees.

6. The L-shaped steel connecting plate module as described in claim 1, wherein, The corner joint frame has a fixed bottom hole in the folded bottom piece.

7. The L-shaped steel connecting plate module as described in claim 6, wherein, The bottom hole of the folded bottom piece is provided with a fixing member.

8. The L-shaped steel connecting plate module as described in claim 7, wherein, The lower fixing component is an expansion screw or bolt.

9. The L-shaped steel connecting plate module as described in claim 8, wherein, The lower fixing component is equipped with at least one gasket.

10. The L-shaped steel connecting plate module as described in claim 1, wherein, The interlocking piece assembly is spot-welded to the first and second interlocking pieces of the corner joint frame to form a single unit.

11. The L-shaped steel connecting plate module as described in claim 1, wherein, The height of the first and second interlocking pieces in the interlocking piece group is equal to, less than, or greater than the height of the first and second jointing pieces in the corner joint frame.

12. The L-shaped steel connecting plate module as described in any one of claims 1 to 11 of the patent application, wherein, The corner joint frame protrudes from the first joint piece and the second joint piece and is respectively fitted and fixed with a lightweight steel section. The lightweight steel section includes an upper plate, a lower plate and a side plate. The upper plate and the lower plate are parallel to each other and the side plate is provided on their inner sides. A recess is formed between the upper plate, the lower plate and the side plate. The inner side of the side plate and the recess are respectively corresponding to and embedded in the first and second interlocking pieces of the interlocking piece group. The side plate of the lightweight steel section is provided with at least one through hole on each side and corresponds to the first connecting through hole of the first interlocking piece and / or the second connecting through hole of the second interlocking piece.

13. The L-shaped steel connecting plate module as described in claim 12, wherein, The interlocking piece assembly is provided with the first connecting hole of the first interlocking piece and the second connecting hole of the second interlocking piece, and the lightweight steel is provided with the hole of the side plate.
