Claims

1. A reusable, detachable independent foundation and rigid connection node for a modular housing, comprising a square tube column (110) serving as vertical support for the modular housing and a precast concrete foundation (200), wherein L-shaped anchor bolts (201) are pre-embedded in the precast concrete foundation (200), and the square tube column (110) is rigidly connected to the precast concrete foundation (200) via a column foot connector (120) fixedly connected to its lower part, characterized in that: The column base connector (120) includes a horizontal connecting part (121), on which a vertical connecting part (122) for connecting with the lower part of the square tube column (110) is integrally formed; a first sealing plate (111) and a second sealing plate (114) are fixed from top to bottom inside the tube of the square tube column (110), the first sealing plate (111) is flush with the upper end of the vertical connecting part (122), and the second sealing plate (114) is fixed at the bottom end of the square tube column (110); a first reinforcing plate (112) and a second reinforcing plate (113) are horizontally fixed between the first sealing plate (111) and the second sealing plate (114), the first reinforcing plate (112) is provided with oblique threaded through holes extending to the left and right, and the second reinforcing plate (113) is provided with oblique threaded through holes extending to the front and back; the column base connector (120) is fixedly connected to the L-shaped anchor bolt (201) through the horizontal connecting part (121).

2. The repeatable, detachable rigid connection of a foundation to a box story of claim 1, wherein: The first reinforcing plate (112) has grooves on its front and rear sides to facilitate welding operations. The grooves have protrusions extending outward on the left and right sides. The protrusions extend and contact the inner wall of the corresponding side column (110). The second reinforcing plate (113) has welding gaps between its left and right sides and the inner wall of the corresponding side column (110). The first reinforcing plate (112) is welded and reinforced through these gaps.

3. The repeatable detachable moment-resisting connection of a foundation to a box column of claim 1, wherein: The vertical connecting part (122) includes cavities for insertion into square tube columns (110), the number of cavities corresponding to the number of square tube columns (110) connected, and multiple cavities sharing the same horizontal connecting part (121).

4. The repeatable, detachable, stand-alone foundation and box house rigid connection of claim 3, wherein: The vertical connecting plates on all four sides of the cavity are provided with oblique thread through holes, with thread inclination angles of 45° or 135°.

5. The reusable detachable independent foundation and rigid connection node of the container house as described in claim 1, characterized in that: The L-shaped anchor (201) extends out of the top surface of the precast concrete foundation (200), and the extended end is provided with a slanted thread. The extended end passes through the horizontal connection part (121) with the column foot connector (120) and is connected to an anti-loosening fastening nut.
