Description

Technical Field

[0001] This utility model belongs to the field of elevator equipment, and more specifically relates to a steel structure for adding an elevator with a platform. Background Technology

[0002] An elevator shaft is the shaft through which elevators are installed. The dimensions of the shaft are determined by the type of elevator selected. Elevator tracks and counterweight tracks are installed on the shaft walls, and elevator doors are installed in pre-drilled doorways. The elevator machine room is located at the top of the shaft. For currently constructed low-rise or high-rise buildings, elevator shafts are typically pre-planned during the design and construction phases, making the installation of these types of supports relatively convenient.

[0003] However, many residential buildings in the last century were low-rise structures with seven floors or less and no elevators. Residents on slightly higher floors had to climb stairs every day. This was especially problematic for the elderly or young people carrying children. Therefore, the guidelines for comprehensively promoting the renovation of old residential areas explicitly encouraged the installation of elevators in buildings where conditions permitted. Since existing elevator shafts were unavailable, it was necessary to construct an elevator shaft on the exterior of the building using pillars, and then fix tempered glass to the outside of the shaft to install the elevator.

[0004] Due to the limitations of the building structure in older residential areas, elevator shafts need to be connected to the building via a platform. However, existing technologies lack platforms for expanding and utilizing the space between elevator shafts and buildings. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a steel structure for elevator installation with a platform, characterized by high structural strength, convenient and flexible space expansion, high safety factor, and the ability to be installed as a whole.

[0006] According to one aspect of the present invention, an elevator steel structure with a platform includes: an elevator shaft steel structure and a platform assembly.

[0007] Several platform components are vertically fixed on one side of the elevator shaft steel structure, with 3-7 platform components in total;

[0008] The platform components include: a fixed platform, which is fixedly connected to the steel structure of the elevator shaft;

[0009] Alternatively, the platform components include a fixed platform and a supporting platform. The fixed platform is fixedly connected to the elevator shaft steel structure, and at least one supporting platform is provided. The supporting platform is installed on one or both sides of the fixed platform and is fixedly connected to the fixed platform and the elevator shaft steel structure. By setting the platform components on one side of the elevator shaft steel structure, it is convenient to connect the elevator shaft to the building and facilitate the movement of passengers. By setting the platform components as a fixed platform and a supporting platform, it is convenient to flexibly expand and utilize space according to different building conditions.

[0010] In some implementations, the elevator shaft steel structure includes a first column, a second column, a third column, and a fourth column. These columns form a vertical rectangular frame and are connected by several fixed rod groups. Utilizing the first, second, third, and fourth columns as the main load-bearing structures, the connecting fixed rod groups ensure high overall structural stability and strength.

[0011] In some implementations, mounting feet are provided at the bottom of the first, second, third, and fourth columns. The first and second columns are located on the side away from the elevator door, while the third and fourth columns are located on the side closer to the elevator door. The mounting feet facilitate the connection between the elevator shaft steel structure and the cast-in-place concrete base.

[0012] In some embodiments, the fixing rod assembly includes: radial fixing rods and axial fixing rods. The radial fixing rods are provided with multiple radial connecting groups arranged radially along the first column, the second column, the third column, and the fourth column to form a circle around the first column, the second column, the third column, and the fourth column. The radial connecting groups are provided with multiple channels.

[0013] The axial fixing rod is vertically fixed between the upper and lower sets of radial fixing rods;

[0014] The third and fourth columns are stronger than the first and second columns. The overall structural strength is increased by multiple radial connection groups and axial fixing rods. At the same time, since the third and fourth columns are the main load-bearing components of the platform assembly, their strength needs to be higher than that of the opposing first and second columns.

[0015] In some embodiments, a plurality of first support blocks are provided on the third and fourth columns. The first support blocks are perpendicular to the third and fourth columns and have a 90° angle with the fixed platform. A second support block is perpendicularly provided on the side of the fixed platform away from the first support blocks. The first and second support blocks ensure that the third and fourth columns bear the load, making the structure safe and reliable.

[0016] In some implementations, the support platform is fixedly connected to the first and second support blocks, and the end of the support platform furthest from the first support block is fixedly connected to a third or fourth column via diagonal bracing. The diagonal bracing ensures the stability and reliability of the support platform structure.

[0017] In some implementations, the number of first support blocks, second support blocks, and diagonal braces is the same as the number of support platforms provided.

[0018] In some implementations, the maximum dimensions of the fixed platform are: 2.5m in length and 1.5m in width.

[0019] In some implementations, the maximum dimensions of the support platform are: 2.0m in length and 1.5m in width.

[0020] Compared with existing technologies, this utility model has the following advantages: high structural strength, convenient and flexible space expansion, high safety factor, and integrated installation. This utility model facilitates the connection between the elevator shaft and the building by setting a platform component on one side of the elevator shaft steel structure, allowing for easy passenger movement. By setting the platform component as both a fixed platform and a supporting platform, it allows for flexible space expansion and utilization based on different building conditions. The first, second, third, and fourth columns serve as the main load-bearing structures, and the connected fixed rod group ensures high overall structural stability and strength. Mounting feet facilitate the connection between the elevator shaft steel structure and the poured concrete base. Multiple radial connection groups and axial fixed rods increase the overall structural strength. Since the third and fourth columns are the main load-bearing components of the platform component, their strength needs to be higher than that of the opposing first and second columns. The first and second support blocks ensure that the third and fourth columns bear the load, ensuring structural safety and reliability. The diagonal bracing ensures the stability and reliability of the supporting platform structure. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0028] In the description of this invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.

[0029] like Figure 1 As shown, the elevator steel structure for the platform described in this utility model includes: elevator shaft steel structure 1 and platform component 2;

[0030] Several platform components 2 are vertically fixed on one side of the elevator shaft steel structure 1, with 3-7 platform components 2;

[0031] Platform component 2 includes: a fixed platform 3, which is fixedly connected to the elevator shaft steel structure 1;

[0032] Alternatively, platform component 2 includes a fixed platform 3 and a supporting platform 4. The fixed platform 3 is fixedly connected to the elevator shaft steel structure 1, and at least one supporting platform 4 is provided. The supporting platform 4 is installed on one or both sides of the fixed platform 3, and the supporting platform 4 is fixedly connected to the fixed platform 3 and the elevator shaft steel structure 1. By setting platform component 2 on one side of the elevator shaft steel structure 1, it is convenient to connect the elevator shaft and the building, facilitating passenger movement. By setting platform component 2 as a fixed platform 3 and a supporting platform 4, it is convenient to flexibly expand and utilize space according to different building conditions.

[0033] In actual production and processes, platform components 2 are typically set to 5 or 6 units; adding more to lower buildings is generally not very meaningful. In practical use, this patent application primarily targets cantilevered steel beams for single-level entrances. Existing technologies require concrete columns for support of these cantilevered steel beams. This invention directly connects platform components 2 to the third and fourth columns 13 and 14, using these columns as the primary load-bearing structures. This eliminates the need for additional columns, allowing platform components 2 to be manufactured directly in the factory and connected to the building. Platform components 2 expand the available space while being manufactured directly in the factory.

[0034] like Figure 2As shown, the elevator shaft steel structure 1 includes: a first column 11, a second column 12, a third column 13, and a fourth column 14. The first column 11, second column 12, third column 13, and fourth column 14 form a vertical rectangular frame, connected by several fixed rod groups. Utilizing the first column 11, second column 12, third column 13, and fourth column 14 as the main load-bearing structure, the connecting fixed rod groups ensure high overall structural stability and strength.

[0035] The bottom of the first column 11, the second column 12, the third column 13, and the fourth column 14 are all equipped with mounting feet 15. The first column 11 and the second column 12 are located on the side away from the elevator door, while the third column 13 and the fourth column 14 are located on the side closer to the elevator door. The mounting feet 15 facilitate the connection between the elevator shaft steel structure 1 and the poured concrete base.

[0036] The fixing rod assembly includes: a radial fixing rod 16 and an axial fixing rod 17. The radial fixing rod 16 is provided with multiple radial connecting groups arranged radially along the first column 11, the second column 12, the third column 13 and the fourth column 14 to form a radial connection group around the first column 11, the second column 12, the third column 13 and the fourth column 14. The radial connecting group is provided with multiple channels.

[0037] The axial fixing rod 17 is vertically fixed between the upper and lower sets of radial fixing rods 16;

[0038] The strength of the third column 13 and the fourth column 14 is higher than that of the first column 11 and the second column 12. The overall structural strength is increased by multiple radial connecting groups and axial fixing rods 17. At the same time, since the third column 13 and the fourth column 14 are the main load-bearing components of the platform assembly 2, their strength needs to be higher than that of the opposing first column 11 and second column 12.

[0039] like Figure 3 As shown, several first support blocks 5 are installed on the third column 13 and the fourth column 14. The first support blocks 5 are perpendicular to the third column 13 and the fourth column 14, and have a 90° angle with the fixed platform 3. A second support block 6 is installed perpendicularly on the side of the fixed platform 3 away from the first support blocks 5. The first support blocks 5 and the second support blocks 6 ensure that the third column 13 and the fourth column 14 bear the load, making the structure safe and reliable.

[0040] like Figure 4 As shown, the support platform 4 is fixedly connected to the first support block 5 and the second support block 6. The end of the support platform 4 away from the first support block 5 is fixedly connected to the third column 13 or the fourth column 14 via a diagonal brace 7. The diagonal brace 7 ensures the structural stability and reliability of the support platform 4. During installation, the other side of the support platform 4 will be fixed to the wall of the building.

[0041] The number of the first support block 5, the second support block 6, and the diagonal brace 7 is the same as the number of the support platform 4.

[0042] The maximum dimensions of fixed platform 3 are: length 2.5m and width 1.5m.

[0043] The maximum dimensions of support platform 4 are: length 2.0m and width 1.5m.

[0044] Through testing and simulation, the maximum specifications of the fixed platform 3 and the supporting platform 4 are the safest and have the greatest expansion potential.

[0045] Platform component 2 is set up according to the specific circumstances of the building to be added, and the following are different ways of doing so.

[0046] Example 1

[0047] like Figure 1 As shown, platform component 2 includes a fixed platform 3 and a supporting platform 4. The fixed platform 3 is fixedly connected to the elevator shaft steel structure 1. Two supporting platforms 4 are provided and installed on both sides of the fixed platform 3. The supporting platforms 4 are fixedly connected to the fixed platform 3 and the elevator shaft steel structure 1. This allows for greater expansion space.

[0048] Example 2

[0049] like Figure 5 As shown, platform component 2 includes: fixed platform 3 and support platform 4. Fixed platform 3 is fixedly connected to elevator shaft steel structure 1. Support platform 4 is provided and installed on one side of fixed platform 3. Support platform 4 is fixedly connected to fixed platform 3 and elevator shaft steel structure 1.

[0050] Example 3

[0051] like Figure 6 As shown, platform component 2 includes a fixed platform 3 and a supporting platform 4. The fixed platform 3 is fixedly connected to the elevator shaft steel structure 1. One supporting platform 4 is installed on one side of the fixed platform 3 and is fixedly connected to the fixed platform 3 and the elevator shaft steel structure 1. The supporting platforms 4 are arranged vertically in a staggered manner.

[0052] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
