AI Technical Summary
The traditional combination structure of the bottom beam and lower beam of elevators occupies too much pit depth and cannot be used in situations where the pit is less than 200 mm, resulting in failure to pass acceptance and high material consumption and long installation cycle.
The bottom beam adopts a box girder structure, combined with the overload device of the upper beam. The load of the upper beam is distributed to the side or shaft sidewall by the diagonal bracing, which reduces the bearing pressure of the bottom beam. The stability of the diagonal bracing is enhanced by high-strength mortar or foam material. The bottom beam is designed to reduce material usage and pit depth requirements.
This technology enables the reduction of bottom beam height, material savings, improved structural stability and safety, optimized force transmission path, shortened installation cycle, and reduced costs when space is limited in the pit.
