Description

Technical Field

[0001] This utility model relates to the field of elevator shaft technology, and in particular to an elevator shaft frame structure. Background Technology

[0002] Currently, home elevators require the highest possible shaft utilization, which necessitates that the thickness of the elevator shaft frame profiles be as thin as possible while still meeting design requirements. Considering varying shaft heights, widths, and depths, the shaft frame design also needs sufficient strength and stability to meet versatility requirements.

[0003] Due to the structural characteristics of the aluminum profiles of the derrick, the connection between the derrick column and the derrick crossbar is inconvenient. In the existing technology, the fixing holes are generally processed on the inner sides of both ends of the crossbar, and then L-shaped sheet metal parts are used to connect the crossbar and the column groove. The processing of the aluminum profile of the crossbar affects the convenience of installation and its structural strength.

[0004] Chinese patent document CN117246874A discloses an assembled elevator shaft frame, including a shaft frame. The shaft frame includes four rectangular shaft columns, with crossbars connecting adjacent columns. Each shaft column includes a column body and two connecting portions respectively disposed on two adjacent sides of the column body. A first bolt slot is provided on the inner side of the connecting portion, extending vertically. A second bolt slot is provided on the inner side of the crossbar. The bolt slot extends laterally; the inner side of the shaft column is provided with a connecting bracket, which includes two fixing plates. The fixing plates are L-shaped and include an integrally connected horizontal plate and a vertical plate. The vertical plates of the two fixing plates are integrally vertically connected. The vertical plate is in contact with the inner side of the connecting part and has a first bolt through hole corresponding to the first bolt slot. The horizontal plate is in contact with the inner side of the crossbar and has a second bolt through hole corresponding to the second bolt slot.

[0005] In the above-disclosed technical solution, the elevator shaft frame crossbars and columns are fixedly connected by an L-shaped fixing plate and an integrated vertical and horizontal plate. L-shaped connectors are installed on the upper and lower sides of both ends of the crossbars. The horizontal space occupied by the connectors affects the selection of the specifications and dimensions of the columns and shaft frame crossbars, causing problems for the stability and installation convenience of the elevator shaft frame. Utility Model Content

[0006] The purpose of this utility model is to provide an elevator shaft structure that can effectively reduce the space occupied by the connection structure between the shaft column and the shaft crossbar, thereby improving the installation convenience and stability of the shaft structure.

[0007] To solve the above-mentioned technical problems, the embodiments of this utility model provide a technical solution as follows:

[0008] An elevator shaft frame structure includes four shaft frame columns arranged in a rectangular shape. A shaft frame crossbar is provided between adjacent shaft frame columns. The shaft frame crossbar has a through sheet metal fixing hole along the axial direction. A sheet metal connector is inserted into the sheet metal fixing hole. A first connecting groove is provided at the end of the shaft frame column and the end of the sheet metal connector. The end of the sheet metal connector is fixedly connected to the first connecting groove by a fastener, thereby connecting and fixing the shaft frame column and the shaft frame crossbar.

[0009] Furthermore, the sheet metal connector is integrally installed through the sheet metal fixing hole, and the two ends of the sheet metal connector are respectively connected to two adjacent columns.

[0010] Furthermore, the sheet metal fixing hole and the sheet metal connector have a U-shaped cross-section, and the sheet metal connector is adapted to fit the sheet metal fixing hole.

[0011] Furthermore, it also includes a column decorative buckle strip, which is snapped onto the open end of the first connecting groove, and the column decorative buckle strip has a wiring groove on the side facing the first connecting groove.

[0012] Furthermore, the derrick column includes two symmetrically arranged extension ends, and a light strip groove is provided at the axis of symmetry of the two extension ends, with the opening ends of the light strip groove located on the same arc surface.

[0013] Furthermore, a second connecting groove is provided between the light strip groove and the first connecting groove, and the opening direction of the first connecting groove is parallel or perpendicular to the opening direction of the second connecting groove.

[0014] Furthermore, the derrick crossbar is provided with an upper slot and a lower slot facing away from each other, and the depth of the upper slot is less than the depth of the lower slot.

[0015] Furthermore, it also includes a button vertical rod, which is arranged parallel to the derrick column. A narrowing crossbar is provided between the button vertical rod and one side of the derrick column, and a short crossbar is provided between the button vertical rod and the other side of the derrick column.

[0016] Furthermore, the button vertical rod includes a first end and a second end.

[0017] Furthermore, decorative panel slots are provided on both sides of the sheet metal connecting groove along the axial direction, and decorative panel slots are provided on both sides of the transition groove along the axial direction. Decorative panels are snapped into the opening ends of the sheet metal connecting groove and the transition groove.

[0018] The elevator shaft structure provided by this utility model, compared with the prior art, uses sheet metal fixing holes axially extending through the shaft shaft crossbars and sheet metal connectors inserted into these holes. This not only achieves the connection and fixation between the shaft shaft crossbars and the shaft shaft columns, but also effectively reduces the space occupied by the connection structure between the shaft shaft columns and crossbars, which is beneficial to improving the installation convenience and stability of the shaft structure. Using fasteners to pass through the sheet metal connectors and connect and fix them to the first connecting groove avoids the need to process connecting holes on the shaft shaft crossbars or shaft shaft columns, which helps to ensure the strength of the shaft shaft crossbars and shaft shaft columns.

A first connecting groove 13 is correspondingly provided at the end of each shaft column 10 and the end of the sheet metal connector 40. The end of the sheet metal connector 40 is fixedly connected to the first connecting groove 13 by a fastener 50, thereby connecting and fixing the shaft columns 10 and the shaft crossbars 20. The connection and fixing between the shaft crossbars 20 and the shaft columns 10 is achieved through the axially extending sheet metal fixing hole 22 and the sheet metal connector 40 inserted into the sheet metal fixing hole 22, while effectively reducing the space occupied by the connection structure between the shaft columns 10 and the shaft crossbars 20, which is beneficial to improving the installation convenience and stability of the shaft structure.

[0039] like Figure 2 As shown, in one embodiment, an elevator shaft frame structure is disclosed. The shaft frame column 10 includes two symmetrically arranged extension ends with identical structures, intersecting at approximately 90°. The side of each extension end facing 90° is the inner side 18, and the side opposite to the inner side 18 is the outer side 17. A light strip groove 12 is centrally located at the intersection of the two extension ends facing inward.

The two ends of the sheet metal connector 40 protrude from the sheet metal fixing hole 22. The two ends of the sheet metal connector 40 are respectively connected and fixed to the adjacent columns by fasteners 50. Multiple shaft crossbars 20 can be arranged in parallel between two adjacent shaft columns 10 to form a stable frame structure. The fasteners 50 and the nut clips are detachably fixed, which helps to increase the convenience of elevator shaft maintenance and replacement. Using fasteners 50 to pass through the sheet metal connector 40 and connect and fix it to the first connecting groove 13 avoids the need to process connecting holes on the shaft crossbars 20 or shaft columns 10, which helps to ensure the strength of the shaft crossbars 20 and shaft columns 10. Preferably, the sheet metal fixing hole 22 has a U-shaped cross-section, and the sheet metal connector 40 has a U-shaped structure adapted to the sheet metal fixing hole 22. By setting the sheet metal connector 40 to have a U-shaped cross-section, the bending strength of the sheet metal connector 40 itself can be effectively increased.
