[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a fully enclosed elevator shaft, including a shaft body 1, a concrete base 2, locking bolts 3, locking nuts 4, locking holes 5, a support plate 6, reinforcing ribs 7, ground anchors 8, positioning bolts 9, positioning nuts 10, positioning holes 11, a clamping plate 12, side bolts 13, tension cables 14, a base plate 15, and wall anchors 16. The bottom of the shaft body 1 is provided with a concrete base 2, and locking bolts 3 are fixed on the side wall of the concrete base 2. Locking nuts 4 are installed at the ends of the locking bolts 3. The locking bolts 3 pass through the locking holes 5, which are opened in the vertical part of the support plate 6. The locking bolts 3 are symmetrically distributed about the center of the support plate 6. The side view shape of the support plate 6 is "L". The above structural design enables the locking bolts 3 to stably install and position the support plate 6, and the support plate 6 can support the shaft body 1.

[0022] During installation, the support plate 6 is moved horizontally close to the locking bolt 3 embedded in the outer wall of the concrete base 2. The locking bolt 3 passes through the locking hole 5. The locking nut 4 is installed on the end of the locking bolt 3 and tightened. Then, the ground anchor 8 is driven into the foundation through the bottom of the support plate 6 to stabilize the support plate 6 on the ground surface and support and position the concrete base 2.

[0023] One side of the support plate 6 is attached to the outer wall of the concrete base 2, and a reinforcing rib 7 is fixedly installed on the other side of the support plate 6. The thickness of the reinforcing rib 7 is greater than the thickness of the support plate 6, and the side view shape of the reinforcing rib 7 is a right-angled triangle. This structural design enhances the structural strength of the support plate 6 and ensures its stable operation over a long period of time. The center of the reinforcing rib 7 is on the same vertical plane as the center of the support plate 6, and the width of the support plate 6 is greater than half the side length of the concrete base 2. This structural design allows the reinforcing rib 7 to cooperate with the support plate 6 to provide support to the concrete base 2. The bottom of the stable support positioning support plate 6 is equipped with ground anchor nails 8. The front side of the outer wall of the shaft body 1 is pre-embedded with positioning bolts 9. The end of the positioning bolts 9 is equipped with positioning nuts 10. The positioning bolts 9 pass through the positioning holes 11. The positioning holes 11 are opened on the front side of the clamping plate 12. The inner side of the clamping plate 12 is in contact with the outer wall of the shaft body 1. The bottom view of the clamping plate 12 is "U" shaped. The clamping plates 12 are evenly distributed on the outer side of the shaft body 1. The above structural design allows the clamping plates 12 to fit tightly with the outer side of the shaft body 1, thus limiting the clamping plates 12 on the shaft body 1.

[0024] Side bolts 13 are provided on the outer side of the clamping plate 12. A tension cable 14 is wound and installed on the side bolts 13. The end of the tension cable 14 is connected and fixed to the center of the base plate 15. Wall anchors 16 are installed through the edge of the base plate 15. The above structural design enables the tension cable 14 to pull and fix the clamping plate 12, ensuring the stability of the shaft body 1. The side bolts 13, tension cable 14 and base plate 15 are symmetrically distributed about the center of the clamping plate 12. Wall anchors 16 are symmetrically and densely installed on both sides of the center of the base plate 15. The above structural design enables the end of the tension cable 14 to be stably fixed, pulling and fixing the clamping plate 12 and the shaft body 1.

[0025] Then, the card plate 12 is brought close to the positioning bolt 9 pre-embedded on the outer wall of the shaft body 1. The positioning bolt 9 passes through the positioning hole 11. The positioning nut 10 is installed on the end of the positioning bolt 9 and tightened. The pulling steel cable 14 is straightened so that the base plate 15 is attached to the surface of the building. The wall anchor nail 16 is used to pass through the base plate 15 and connect to the wall to fix the card plate 12 and pull and position the shaft body 1 as a whole.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
