Description

Technical Field

[0001] This utility model belongs to the technical field of steel platform devices, specifically relating to a steel platform device for complex building elevator shafts. Background Technology

[0002] Traditionally, steel pipe scaffolding is used to construct elevator shafts in high-rise buildings to facilitate the erection of safety barriers and isolation measures within the shaft, as well as safety protection in the operating area. For example, the existing patent with publication number CN209556330U describes a construction operation platform with a robust and reliable structure, high safety performance, and complete assurance of construction safety, giving construction workers a high sense of security. Furthermore, its direct hoisting avoids damage to the shaft walls and collisions with the support structures, making the hoisting process safe, convenient, quick, time-saving, labor-saving, and highly efficient.

[0003] Traditional elevator shaft masonry construction typically involves using heavy machinery to hoist materials to the construction floors or manual transport. This is particularly problematic for uniquely shaped high-rise buildings like towers, where the secondary structure phase, after the main core construction is complete, struggles to use external heavy machinery to hoist materials to the construction floors, posing safety hazards. Furthermore, existing elevator shafts lack safety protection devices for lifting operations during construction. Therefore, this invention provides a steel platform device for complex building elevator shafts. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a steel platform device for complex building elevator shafts. The device consists of a steel frame composed of a first steel pipe, a second steel pipe, a connecting plate, and a corrugated steel plate. This frame is fixed to the structural beams within the elevator shaft, serving as a safe hoisting structure. It can meet the requirements for hoisting materials in the secondary stages of complex building construction and can be used with an electric winch for material transport. The device is simple, has high hoisting efficiency, is safe and reliable, and is highly versatile, suitable for hoisting materials in various elevator shafts, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel platform device for a complex building elevator shaft, comprising a steel frame and an I-beam installed in the elevator shaft. The steel frame includes two first steel pipes and two second steel pipes. The first steel pipes and the second steel pipes, the two first steel pipes and the two second steel pipes are fixed by connecting plates. Two corrugated steel plates are provided between the two first steel pipes, and reinforcing bars are inserted through the corrugated steel plates. Grooves are provided at the front ends of the two first steel pipes, and the two ends of the reinforcing bars are rotatably connected to the two grooves respectively. A hoisting assembly is fixedly provided on the top of the I-beam.

[0006] Furthermore, two symmetrically distributed angle steels are provided between the two corrugated steel plates. The angle steels are fixed to the first steel pipe to support the corrugated steel plates after they are closed. The connecting plate is fixed to the structural beam in the elevator shaft.

[0007] Furthermore, one of the first steel pipes has two mounting slots on one side, and a first motor is fixedly installed inside each of the two mounting slots. The output shaft of the first motor is fixed to one end of the reinforcing bar. The first motor drives the reinforcing bar to rotate the corrugated steel plate, thereby enabling the automatic opening and closing of the two corrugated steel plates.

[0008] Furthermore, the hoisting assembly includes an electric winch with a wire rope wound on it. A hook is connected to the bottom end of the wire rope. A through hole is provided at the top of the I-beam, through which the wire rope passes. The electric winch automatically winds up the wire rope, thereby improving the efficiency of material hoisting.

[0009] Furthermore, a pad is fixedly provided at the front end of each of the two first steel pipes, and a guardrail is provided on the top of the pad. Support plates are fixedly provided on both sides of the top of the pad. A rotating rod is rotatably connected between the two support plates. The rotating rod passes through the guardrail and is fixed to the guardrail. The guardrail can play a protective role between the staff and the elevator shaft opening.

[0010] Furthermore, a fixing groove is provided on one side of the pad, and a second motor is fixedly installed inside the fixing groove. The output shaft of the second motor is fixed to one end of the rotating rod. The second motor drives the rotating rod and the guardrail to rotate, thereby realizing the automatic folding of the guardrail.

[0011] Furthermore, a foot switch is embedded in the top of the pad, and the foot switch is connected to the second motor through a wire, which makes it convenient for workers to quickly operate the guardrail to fold, thereby improving the material unloading rate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a steel frame composed of a first steel pipe, a second steel pipe, a connecting plate, and a corrugated steel plate. When fixed to the structural beam inside the elevator shaft, it can be used as a hoisting safety structure. It can meet the hoisting requirements of materials in the secondary stage of complex buildings. It can also be used with an electric winch to realize the hoisting of materials. The device is simple, has high hoisting efficiency, is safe and reliable, and has strong versatility. It is suitable for hoisting materials in various elevator shafts.

[0014] 2. By installing guardrails on the pad, the safety of workers pulling and hoisting materials can be improved. At the same time, the guardrails are driven to rotate and fold by a second motor and a rotating rod, which makes it convenient for workers to quickly retrieve materials. After the materials are retrieved, the guardrails are reset to continue to provide protection. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5 This utility model provides a steel platform device for elevator shafts in complex buildings, including a steel frame 1 and an I-beam 2 installed in the elevator shaft. The steel frame 1 includes two first steel pipes 101 and two second steel pipes 102. The first steel pipes 101 and the second steel pipes 102, the two first steel pipes 101 and the two second steel pipes 102 are all fixed by connecting plates 103.

[0025] Two corrugated steel plates 104 are provided between the two first steel pipes 101, and steel bars 105 are inserted through the corrugated steel plates 104. The front ends of the two first steel pipes 101 are provided with grooves 106. The two ends of the steel bars 105 are rotatably connected to the two grooves 106 respectively. Two mounting slots 5 are provided on one side of one of the first steel pipes 101. A first motor 6 is fixedly installed inside the two mounting slots 5. The output shaft of the first motor 6 is fixed to one end of the steel bar 105.

[0026] Two symmetrically distributed angle steels 4 are provided between the two corrugated steel plates 104. The angle steels 4 are fixed to the first steel pipe 101 by the first bolt. The connecting plate 103 is fixed to the structural beam in the elevator shaft by the second bolt. A hoisting assembly 3 is fixed to the top of the I-beam 2. Specifically, the hoisting assembly 3 includes an electric winch 301, on which a wire rope 302 is wound. A hook 303 is connected to the bottom end of the wire rope 302. A through hole 7 is opened at the top of the I-beam 2, through which the wire rope 302 passes.

[0027] In practical use, firstly, the I-beam 2 is installed in the elevator shaft of the building's hoisting floor. Then, the electric winch 301 is installed on top of the I-beam 2, and the wire rope 302 and hook 303 are lowered to the ground through the perforation 7 for vertical transportation. Subsequently, a steel frame 1 consisting of two first steel pipes 101, two second steel pipes 102, multiple connecting plates 103, and two corrugated steel plates 104 is placed in the elevator shaft (the floor where materials need to be hoisted for construction), and a large number of bolts are used to fix it to the structural beams in the elevator shaft through the first steel pipes 101 and second steel pipes 102. When the materials are hoisted to the construction floor by the electric winch 301, the first motor 6 drives the reinforcing bar 105 to rotate and open the corrugated steel plate 104. The workers secure their safety ropes to the floor beams, and then use a hook rope tool to pull the materials to the construction floor. After the materials are hoisted, the two corrugated steel plates 104 are closed and placed on the angle steel 4 to prevent objects from falling from the construction floor and reduce safety hazards. The same construction steps apply to the remaining construction floors requiring material hoisting. This embodiment solves the problem of transporting materials to the construction floors after the main structure of a complex building is completed; moreover, the device has a simple structure, high hoisting efficiency, safety and reliability, and strong versatility, making it suitable for hoisting materials in various elevator shafts.

[0028] Refer to the instruction manual appendix Figure 1 , Figure 2 , Figure 3 and Figure 5Each of the two first steel pipes 101 has a pad 8 fixed at its front end. The top of the pad 8 has a guardrail 9. Support plates 10 are fixed on both sides of the top of the pad 8. A rotating rod 11 is rotatably connected between the two support plates 10. The rotating rod 11 passes through the guardrail 9 and is fixed to the guardrail 9. A fixing groove 12 is opened on one side of the pad 8. A second motor 13 is fixed inside the fixing groove 12. The output shaft of the second motor 13 is fixed to one end of the rotating rod 11. A foot switch 14 is embedded in the top of the pad 8. The foot switch 14 is connected to the second motor 13 through an electric wire.

[0029] By installing the guardrail 9 on the rotating rod 11, when hoisting materials into the floor, workers can step on the foot switch 14 to control the rotation of the second motor 13. The second motor 13 drives the rotating rod 11 to automatically rotate and fold the guardrail 9, thus facilitating workers to quickly retrieve the materials. After retrieving the materials, the second motor 13 drives the rotating rod 11 to rotate back, causing the guardrail 9 to return to its original position and continue to provide protection.
