Description

Technical Field

[0001] The utility model relates to the field of installing elevators, in particular to an assembled elevator shaft frame with a boltless mortise and tenon structure. Background Art

[0002] Traditional elevator shaft frames mainly have two structural types: concrete and steel. Concrete elevator shaft frames usually have space reserved in advance at the beginning of new construction, which is not only expensive but also affects the layout of the building. Steel structure elevator shaft frames generally use I-beams as crossbeam columns, which have the advantages of easy installation and fast construction speed.

[0003] For example, Chinese patent document (CN108502670A) discloses an assembled elevator shaft support, wherein a column foot support plate is fixedly arranged at the bottom of a steel column, and the steel column is vertically fixedly arranged on the column foot bottom plate through the column foot support plate, and a steel beam is horizontally fixedly arranged between the steel columns; an end plate is fixedly arranged on the top of the steel beam, and a steel beam support top plate is fixedly arranged between the end plate and the steel beam; the steel beam is connected to the steel column by high-strength bolts through the riveting holes on the end plate that match the riveting holes on the flange plates and the riveting holes on the web at the upper and lower ends of adjacent steel columns, and a channel steel is fixedly arranged on the web between the steel column reinforcement plates at the upper and lower ends of adjacent steel columns; the column foot support plate includes a No. 1 column foot support plate and a No. 2 column foot support plate, the No. 1 column foot support plate is riveted fixed to the outer side of the flange plate of the steel column, and the No. 2 column foot support plate is riveted fixed to both sides of the web of the steel column.

[0004] In the prior art taking this technical solution as an example, the main structures of the steel structure elevator shaft frame need to be connected by bolts or the like, which can easily lead to the exposure of the bolts and affect the operation of the elevator. The use of a large number of bolts will also prolong the construction time and reduce the construction efficiency. Utility Model Content

Then the top column 12 is correspondingly installed on the connecting column 11, so that the first docking beam 22 and the second docking beam 23 are docked with the corresponding top column 12. Repeat the above process, dock the middle connecting beam 21 in the middle connecting groove 4 of the top column 12, and then dock the first docking beam 22 and the second docking beam 23 in the top connecting groove 5 of the top column 12. After all the columns 1 and the I-beam beams 2 are docked, full welding is performed at the mortise and tenon joint positions to form a double safety guarantee and improve the reliability of the elevator shaft frame.
