Description

Technical Field

[0001] The utility model belongs to the technical field of elevator hoistways, and specifically discloses a node structure of an elevator hoistway. Background Art

[0002] With the progress of social technology, elevators have been gradually popularized in daily life. More and more old multi-story buildings in residential areas urgently need to install elevators. Generally, a steel structure elevator hoistway is installed on the periphery of the building. The elevator hoistway is the passage for the elevator to move up and down, and it determines the size of the space occupied by the elevator. This type of elevator is different from the elevators in high-rise buildings and pursues higher space utilization rate.

[0003] During the construction process of elevator installation, the node structure of the elevator hoistway is generally assembled on-site according to the drawings for the columns and crossbeams. Using columns will make the overall size of the hoistway frame larger, resulting in a larger space occupied by the elevator. In addition, due to the narrow space of the construction environment, it is difficult to install and position the node structure of the elevator hoistway. The on-site assembly project progresses slowly, increasing the installation cost and having a certain impact on the project efficiency. Most of the connection nodes between the crossbeams and steel columns adopt welding technology. Due to the influence of the construction environment and space, it is difficult to control the construction quality. The uneven weld structure and weld quality of the connection nodes between the crossbeams and steel columns lead to uneven structural performance of the welds, thus affecting the project quality.

The crossbeam and the square steel are connected through the connecting pieces.

[0007] Further, in the node structure of the elevator hoistway, the crossbeam includes a top plate and a bottom plate arranged in parallel, and an end plate is arranged between the ends of the top plate and the bottom plate. The end of the crossbeam extends into the installation groove, the outer side wall of the end plate is attached to the inner side wall of the installation groove, and the top plate and the bottom plate of the crossbeam are attached to the edge of the installation groove. A plurality of connecting pieces are arranged between the side surface of the square steel and the top plate and the bottom plate of the crossbeam.

[0008] Further, for the node structure of the elevator hoistway, the cross beam includes a first cross beam and a second cross beam. The bottom plate of the first cross beam is arranged in contact with the top plate of the second cross beam, and the first cross beam and the second cross beam are connected by a number of reinforcing bolts passing through the bottom plate of the first cross beam and the top plate of the second cross beam.
