Technical Field
[0001] This utility model relates to the technical field of unloading steel platforms, specifically an unloading steel platform for building construction. Background Technology
[0002] As an indispensable key facility in the construction industry, unloading steel platforms are mainly used for the temporary storage and transfer of various materials, such as reinforcing bars, formwork, and concrete components. Depending on the application scenario, unloading steel platforms can be further subdivided into several types, including cantilevered, ground-mounted, attached, and mobile. Among them, cantilevered unloading steel platforms are mostly used in the exterior facade construction of high-rise buildings, generally fixed to the outer frame beams or shear walls of the building structure, and arranged at intervals along the floor height.
[0003] Existing steel unloading platforms for construction are typically installed on the outside of the building's outer frame beams to facilitate the transfer of various building materials. However, these platforms cannot be retracted into the building during rainy weather. After prolonged use, the steel is susceptible to erosion from rainwater, damp environments, or chemical corrosion, which weakens its cross-sectional strength and reduces its load-bearing capacity. To prevent the unloading steel platform from being affected by rainwater erosion and thus its load-bearing performance, this application proposes a steel unloading platform for construction.

[0027] The movable platform 2 includes a movable fixing frame 201, a platform steel plate 202 is fixedly connected to the top of the movable fixing frame 201, and multiple platform connecting seats 203 are fixedly connected at even intervals on the side of the movable fixing frame 201 away from the horizontal mounting frame 1. Multiple drainage holes 204 are evenly spaced through both ends of the platform steel plate 202. By setting the movable fixing frame 201, the structural strength can be increased and the transfer of building materials can be better facilitated.
[0028] The horizontal mounting frame 1 includes a horizontal connecting rod 101. Multiple horizontal mounting rods 102 are fixedly connected at even intervals on one side of the horizontal connecting rod 101. Two limiting rods 103 are fixedly connected at symmetrical intervals on both sides of the bottom of the multiple horizontal mounting rods 102. A base plate 104 is fixedly connected to the bottom of the two limiting rods 103. The two limiting rods 103 and the base plate 104 facilitate the fixing of multiple movable support rods 4, enabling them to move stably and support the movable platform 2.
[0029] The movable fixing frame 201 is rotatably connected to the horizontal connecting rod 101 on one side.
[0030] The vertical mounting frame 3 includes multiple vertical mounting rods 301. A winch mounting plate 302 is fixedly connected to one side of the top of the multiple vertical mounting rods 301. The bottom of the vertical mounting rods 301 is fixedly connected to multiple horizontal mounting rods 102. By setting the winch mounting plate 302, two motor winch components 7 can be installed, which facilitates the raising and lowering of the movable platform 2.
[0031] The movable support rod 4 includes a support rod 401. Two roller mounting plates 402 are symmetrically fixed to both sides of one end of the support rod 401. The support rod 401 is slidably connected between the two limiting rods 103 and the base plate 104. Multiple rollers 403 are evenly spaced and rotatably connected to the two roller mounting plates 402. The multiple rollers 403 are respectively tumbling connected to the two limiting rods 103.

[0036] Among them, the bottom of the two guardrails 5 are fixedly connected to both ends of the upper surface of the platform steel plate 202. By setting multiple guardrails 5, protection can be formed on the mobile platform 2, which facilitates safer transportation of building materials.
[0037] Working principle: By fixing multiple horizontal mounting rods 102 to the building frame beam, the two winch motors 703 on the upper and lower sides drive the rotating shaft 702 to rotate, which in turn drives multiple winches 704 to rotate, releasing multiple strands of hoisting rope 9, causing the movable fixed frame 201 to rotate around the horizontal connecting rod 101 and slowly lower. The movable platform 2 uses multiple pulleys 6 to hold the upper strands of hoisting rope 9, so that the upper strands of hoisting rope 9 drive the supporting connecting rod 801 through the rod connecting seat 802, which in turn drives multiple supporting rods 401 to slide out through multiple rollers 403 along the channel formed by the two limiting rods 103 and the bottom plate 104, so that the multiple supporting rods 401 contact the bottom of the movable platform 2, thereby supporting the bottom of the movable platform 2.
