Description

Technical Field

[0001] This utility model relates to the field of elevator shaft frames, and more particularly to an elevator shaft frame assembled with L-shaped steel. Background Technology

[0002] The existing elevator shaft column structure is not particularly robust and stable. The thin column structure has limited load-bearing capacity when subjected to various heavy loads during elevator operation. This may lead to deformation and damage of the column, seriously affecting the safe operation of the elevator. Once the column has a problem, it may cause safety accidents such as elevator jamming, shaking or even falling, posing a great threat to the lives of passengers. In addition, an unstable shaft structure may also affect the stability of elevator operation, reduce the comfort of riding, and shorten the service life of the shaft, increasing maintenance and replacement costs. Summary of the Invention

[0003] In view of this, the present invention provides an elevator shaft frame assembled with L-shaped steel. The main technical problem to be solved is to address the problem that the existing elevator shaft frame column structure is too thin, resulting in insufficient load-bearing capacity, affecting the safe operation of the elevator, reducing ride comfort, and increasing maintenance costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an elevator shaft frame assembled with L-shaped steel, comprising a base, a shaft frame one and multiple shaft frames two, wherein the shaft frame one is fixedly installed on the top of the base, and the multiple shaft frames two are sequentially fixedly installed on the top of the shaft frame one, wherein the base, shaft frame one and shaft frames two are each provided with multiple columns and beams inside;

[0005] The base, derrick one, and derrick two are each equipped with four rectangular columns, and multiple crossbeams are bolted between adjacent columns.

[0006] The column includes an L-shaped plate one and an L-shaped plate two, and there are two L-shaped plates two, which are symmetrically welded to the inner wall of the L-shaped plate one;

[0007] Multiple crossbeams are bolted between two adjacent L-shaped plates, and a crossbeam is bolted at the junction of the L-shaped plates of the upper and lower columns.

[0008] A square reinforcing steel plate is welded to the inner wall of the L-shaped plate one. The square reinforcing steel plate is located between the two L-shaped plates two and is welded and fixed to the two L-shaped plates two.

[0009] The two L-shaped plates are fixedly connected by an L-shaped connecting plate.

[0010] By adopting the above technical solutions, the overall structural strength and load-bearing capacity of the elevator shaft are enhanced, thereby improving the safety and stability of elevator operation.

[0011] As a further description of the above technical solution: the outer walls of the two L-shaped plates of the L-shaped plate one are bolted together with multiple triangular reinforcing ribs.

[0012] By adopting the above technical solutions, the structural strength of the column is further enhanced, and its ability to resist external deformation is improved.

[0013] As a further description of the above technical solution: a diagonal tie rod is bolted between two adjacent crossbeams on the same side, and the diagonal tie rod is fixedly connected between the L-shaped plate and the two opposite angles of the crossbeam in a Z-shape installation.

[0014] By adopting the above technical solution and utilizing the stability principle of triangles, the overall rigidity of the hoistway is enhanced, enabling it to better withstand various forces generated during elevator operation.

[0015] As a further description of the above technical solution: two crossbeams are installed between two adjacent columns on the base, five crossbeams are installed between two adjacent columns on the first derrick, and four crossbeams are installed between two adjacent columns on the second derrick.

[0016] By adopting the above technical solution, the number of crossbeams was rationally set according to the stress characteristics of different parts, thus optimizing the stress distribution of each part of the elevator shaft. This effectively solved the impact of high-intensity earthquakes on the elevator shaft.

[0017] By employing the above technical solution, the elevator shaft frame assembled with L-shaped steel of this utility model has at least the following beneficial effects:

[0018] 1. Compared with existing technologies, this elevator shaft frame assembled with L-shaped steel, by setting up L-shaped plate one, L-shaped plate two, and square reinforcing steel plate, forms the shaft frame columns in use. The composite structure formed by L-shaped plate one and L-shaped plate two symmetrically welded to its inner wall, and the square reinforcing steel plate welded to the inner wall of L-shaped plate one and located between the two L-shaped plates two, increases the load-bearing area of ​​the columns, improves the bending and compressive strength of the columns, solves the problem of thin columns in existing elevator shaft frames, enhances the load-bearing capacity of the columns, ensures the safe operation of the elevator, reduces the risk of safety accidents caused by column problems, improves ride comfort, extends the service life of the shaft frame, and reduces maintenance costs.

[0019] 2. Compared with the existing technology, this elevator shaft frame assembled with L-shaped steel, by setting L-shaped connecting plates, triangular reinforcing ribs and diagonal braces, allows the upper and lower columns to be firmly connected together by bolts during use. At the same time, the strength of the columns is further enhanced by setting triangular reinforcing ribs. The diagonal braces enable the columns and beams to form a more stable whole, enhancing the overall rigidity and stability of the shaft frame. Attached Figure Description

[0027] Reference Figures 1-5This utility model provides an elevator shaft frame assembled with L-shaped steel: It includes a base 1, serving as the foundation of the elevator shaft frame, providing stable support for the entire shaft frame and bearing the weight of the upper structure and elevator equipment; a shaft frame 2, located on top of the base 1, connecting the base 1 and the shaft frame 3, acting as the intermediate support structure of the elevator shaft frame; and multiple shaft frames 3, sequentially installed on top of the shaft frame 2 to increase the height of the shaft frame to accommodate elevator requirements of buildings of different heights. The shaft frame 2 is fixedly installed on top of the base 1, and the multiple shaft frames 3 are sequentially fixedly installed on top of the shaft frame 2. Multiple columns 4 are provided inside the base 1, shaft frame 2, and shaft frame 3, serving as the main load-bearing components of the shaft frame, bearing various loads during elevator operation; and crossbeams 5, connecting adjacent columns 4 to enhance the overall rigidity and stability of the shaft frame. Each base 1, shaft frame 2, and shaft frame 3 has four rectangularly distributed columns 4 inside, with multiple crossbeams bolted between adjacent columns 4. Beam 5; Column 4 includes L-shaped plate 1 401 and L-shaped plate 2 402. L-shaped plate 2 402 and L-shaped plate 1 401 together form a composite structure of column 4, enhancing the strength of column 4. There are two L-shaped plates 2 402, which are symmetrically welded to the inner wall of L-shaped plate 1 401. Multiple crossbeams 5 are bolted between adjacent L-shaped plates 2 402 to ensure a stable connection between the crossbeams 5 and column 4, which is conducive to the transmission of force. The L-shaped plates 2 402 of the upper and lower columns 4 intersect. A crossbeam 5 is bolted to the position; a square reinforcing steel plate 8 is welded to the inner wall of the L-shaped plate 401. The square reinforcing steel plate 8 is located between the two L-shaped plates 402 and is welded and fixed to the two L-shaped plates 402 to further enhance the strength and load-bearing capacity of the column 4; the upper and lower L-shaped plates 401 are fixedly connected by an L-shaped connecting plate 9. The L-shaped connecting plate 9 is used to connect the upper and lower L-shaped plates 401 to ensure that the connection between each derrick is firm and that the derrick can work together when under stress.

[0028] The outer walls of the two L-shaped plates 401 and 402 are bolted together with multiple triangular reinforcing ribs 7 to enhance the structural strength of the column 4 and improve its ability to resist external deformation.

[0029] A diagonal tie rod 6 is bolted between two adjacent crossbeams 5 on the same side. The diagonal tie rod 6 is fixedly connected between the two opposite angles of the L-shaped plate 402 and the crossbeam 5 in a Z-shape installation, which utilizes the stability principle of triangles to enhance the overall rigidity of the derrick.

[0030] Two crossbeams 5 are installed between two adjacent columns 4 on the base 1. Based on the stress characteristics of the base 1, the number of crossbeams 5 is set reasonably to ensure the stability of the base 1. Five crossbeams 5 are installed between two adjacent columns 4 on the derrick 1 2. Considering the height and stress of the derrick 1 2, the number of crossbeams 5 is optimized to ensure the structural stability of the derrick 1 2. Four crossbeams 5 are installed between two adjacent columns 4 on the derrick 2 3. Based on the position and stress requirements of the derrick 2 3, the number of crossbeams 5 is determined reasonably to ensure the stability of the derrick 2 3.

[0031] Working principle: First, align the column 4 at the bottom of the derrick 2 with the column 4 at the top of the base 1. Secure the L-shaped connecting plate 9 to the L-shaped plate 401 of the upper and lower columns 4 with bolts to ensure a stable connection between the two columns 4. Further reinforce the outside of the two columns 4 with triangular reinforcing ribs 7. Multiple evenly distributed triangular reinforcing ribs 7 are bolted on the columns 4 to enhance the strength and stability of the columns 4.

[0032] Subsequently, the second derrick 3 is installed on top of the first derrick 2 in the same way as described above, using the L-shaped connecting plate 9 inside the column 4 and the triangular reinforcing rib plate 7 on the outside for connection and fixation. If multiple second derricks 3 need to be installed above the second derrick 3, they are connected in sequence according to the same installation method.

[0033] During elevator operation, the weight of the elevator car and counterweight is transferred to the column 4 through the guide rail. The column 4, which is composed of L-shaped plate 1 401, L-shaped plate 2 402 and square reinforcing steel plate 8, can effectively withstand the pressure and bending moment generated by these weights due to its composite structure and the role of the reinforcing steel plate.

[0034] The L-shaped connecting plate 9 ensures the firmness of the connection between each derrick, enabling the derrick to work together when under stress. The triangular reinforcing rib plate 7 further enhances the strength of the column 4, making it less prone to deformation when subjected to external forces.

[0035] The diagonal bracing 6 between adjacent crossbeams 5 on the same side forms a stable triangular structure with the crossbeams 5, which enhances the overall rigidity of the hoist and effectively resists external forces such as vibration and impact generated during elevator operation, ensuring the safe and stable operation of the elevator.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
