[0002] In the field of modern architecture, indoor elevators have become an indispensable infrastructure for high-rise buildings, and their safe and stable operation directly affects the user experience and the safety of people and property. As a key load-bearing structure for elevator operation, the shaft steel frame device undertakes the important functions of supporting the elevator car, the balancing system, and guiding the vertical movement of the elevator. With the increasing diversification of architectural design styles and the continuous emergence of demand for elevator retrofitting in older buildings, the size specifications and installation environment of elevator shafts are showing significant differences. Existing indoor elevator shaft steel frame devices usually use support rods for support. The support area of the support rods is relatively small, which means that as the height of the elevator shaft increases, the number of support rods increases, thereby increasing the construction difficulty and reducing construction efficiency. To address this, this utility model proposes a steel frame device for an indoor elevator steel structure bending component shaft. Utility Model Content

[0027] Example
[0028] like Figure 1 and Figure 2 As shown, this utility model proposes a steel frame device for an indoor elevator steel structure bending component shaft, comprising: four steel frame columns 1 arranged in a rectangular array; a shim 10 fixedly installed at the lower end of each steel frame column 1; the shim 10 increases the contact area between the steel frame column and the ground, evenly distributing the weight of the shaft device, preventing the steel frame column from sinking into the ground, ensuring the stable support of the entire steel frame device, and avoiding tilting or settlement due to uneven ground force. A splicing groove 11 is provided on one side of each steel frame column 1, and sliding grooves 2 are provided on both sides of each steel frame column 1. The sliding grooves 2 are T-shaped. One side of each steel frame column 1 is fixedly welded to a fixing plate 3 via the splicing groove 11. The fixing plate 3 is bent at 90 degrees, allowing it to form a vertical connection structure with adjacent components, facilitating the construction of the shaft frame system and enhancing the rigidity and stability of the shaft in the horizontal direction. Multiple first through holes 4 are provided on both sides of the fixing plate 3. The first through holes 4 are used to connect with other components through fasteners and other connectors, which facilitates the assembly and disassembly of different components and improves the installation efficiency and maintenance convenience of the shaft steel frame device.
[0029] Furthermore, a slider 5 is slidably installed inside the slide chute 2. The slider 5 has a "T"-shaped structure, which increases the stability of its movement. A connecting plate 6 is fixedly installed at one end of the slider 5. The connecting plate 6 has a 90-degree bend, which allows it to connect with components such as the support beam at a perpendicular or specific angle, thereby effectively transferring the supporting force to the steel frame column and enhancing the support performance of the hoistway steel frame device in different directions. A second through hole 7 is opened on one side of the connecting plate 6. A fastening bolt 8 passes through the second through hole 7 and the first through hole 4, which can firmly connect the connecting plate 6 and the fixed plate 3 together, ensuring that there is no relative displacement between the support components and the steel frame column during elevator operation, thus guaranteeing the structural stability and safety of the entire hoistway steel frame device.
[0030] like Figure 3 and Figure 4As shown, a support assembly 9 for stabilizing the steel frame column 1 is fixedly installed between the connecting plates 6. The support assembly 9 includes a support beam 91 fixedly installed between the connecting plates 6. The support beam 91 is a U-shaped bend. The U-shaped support beam can provide strong support for the steel frame column in the horizontal direction, disperse the horizontal load generated during elevator operation, effectively prevent lateral deformation or swaying of the steel frame column, and improve the overall stability of the shaft steel frame device. Guide slots 92 are respectively opened on both sides of the support beam 91. A set of guide limit bolts 93 are slidably installed inside the guide slots 92. The cooperation of the guide slots 92 and the guide limit bolts 93 allows the first support rod 94 and the second support rod 95 to flexibly adjust their position and angle along the guide slots to adapt to the installation requirements of shafts with different heights and spans, enhancing the versatility and adaptability of the support assembly.
[0031] Furthermore, the supporting beams 91 are connected by a shaft with a first support rod 94 and a second support rod 95 that rotate relative to each other, enabling stable rotation of the first support rod 94 and the second support rod 95 and facilitating adjustment of the support angle and position. The two ends of the first support rod 94 and the second support rod 95 are respectively movably connected to guide limit bolts 93, which increases the support area of the supporting beams 91. A set of fixed columns 96 is fixedly installed on one side of the first support rod 94, with a limit rod 97 movably connected to one end of the fixed column 96, and a limit bolt 98 fixedly connected to one end of the limit rod 97. Two limit through holes 99 are opened on one side of the second support rod 95, which are movably connected to the limit bolts 98. By adjusting the position of the limit rod 97 on the fixed column 96 and inserting the limit bolts 98 into the limit through holes 99, the angle between the first support rod 94 and the second support rod 95 can be precisely locked, enabling the support assembly to provide stable and reliable support according to the actual stress conditions, further ensuring the safety and stability of the indoor elevator steel structure bending component shaft steel frame device.
[0032] In this embodiment, the four steel frame columns 1 are first vertically fixed in predetermined positions, and the pads 10 at their lower ends increase the contact area with the ground to improve stability. Then, the steel frame columns 1 are fixedly welded to the fixing plate 3 through the splicing groove 11.
[0033] Subsequently, slider 5 is slid into groove 2. Utilizing the "T"-shaped structure, slider 5 slides stably within groove 2, and connecting plate 6 at one end of slider 5 moves accordingly. When hoisting support components 9 such as support beam 91, connecting plate 6 drives support beam 91 to rise smoothly along groove 2, avoiding impact with the shaft interior due to shaking during hoisting, ensuring the safety of support beam 91 hoisting, reducing the risk of damage, and improving construction efficiency.
[0034] After the support beam 91 is hoisted to a suitable height, the connecting plate 6 is fixed by fastening bolts 8 passing through the second through hole 7 of the connecting plate 6 and the first through hole 4 of the fixing plate 3. At this time, the guide limit bolts 93 in the guide slots 92 on both sides of the support beam 91 slide and adjust, and the guide limit bolts 93 drive the first support rod 94 and the second support rod 95 to rotate to form a support structure. After the first support rod 94 and the second support rod 95 have moved to a suitable position, the nuts at both ends of the guide limit bolts 93 are tightened, thereby limiting the first support rod 94 and the second support rod 95.
[0035] Subsequently, the limiting rod 97 on the rotating fixed column 96 moves, and the limiting rod 97 drives the limiting bolt 98 at one end to be inserted into the limiting through hole 99 and tightened by the nut, thereby stably limiting the first support rod 94 and the second support rod 95, increasing the support area of the steel frame column 1, ensuring stable support effect, reducing construction difficulty, effectively improving construction efficiency, and completing the stable support of the shaft.
[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
