[0002] The first floor of this project is a steel structure project, consisting of two multi-story structural units and a multi-story corridor. The corridor is located high and wide. When construction is carried out at the bottom of the large-span corridor, due to the large span and long depth of the corridor, ordinary hanging baskets can only be set up on both sides, and it is impossible to carry out in-depth construction in the depth of the corridor. At the same time, the area above the top plate of the bottom structure cannot be entered by super-high work vehicles for construction, and workers are constructing in an area without a safe and reliable construction operation surface.

[0003] Conventional hanging baskets are inadequate for bottom curtain wall construction. A new design allows holes to be drilled in the floor slab to suspend the wire ropes, with a suspension platform mounted beneath them. Holes of appropriate dimensions are drilled in the floor slab to ensure the hanging basket can cover the entire work surface during movement. This new hanging basket is easy to install and remove, providing a safe and stable construction surface while ensuring full coverage within the work area, while also reducing installation and rental costs.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figure 1 , which is the first embodiment of the utility model, provides a hanging basket for a large-span steel structure. By opening holes on the surface of the floor slab, the suspension assembly is fixed above the floor slab through the holes, so that the hanging basket is fixedly connected below. At the same time, the stability of the entire device is improved by a safety rope and a falling stone.

[0027] Specifically, the floor slab 100 is a 120mm thick steel truss floor slab with a concrete strength grade of C35. The empirical calculation shows that the service strength is met. A suspension component 101 is fixed on the floor slab 100. The bottom of the suspension component 101 is fixedly connected to a hanging basket 102. The hanging basket 102 is an assembled platform, which consists of a front railing, a rear railing, a base frame and a mounting frame. The components are connected with bolts, and the joints should be firm and not loose. The longitudinal inclination angle of the suspension platform during operation should not be greater than 8°, and the lateral inclination angle should not be greater than 3°. A locking component 103 is fixedly connected to the top of the suspension component 101 to fix the hanging basket 102 and increase the safety of the hanging basket 102.

[0028] Furthermore, a safety rope 104 is fixedly connected to one side of the suspension component 101. The safety rope 104 is independently set, made of nylon, with a diameter of not less than 16 mm, and the rope lock is set as required. The connection between the safety rope 104 and the suspension component 101 is reliable, and one is used as a backup. A drop rock 105 is fixedly connected to the bottom of the hanging basket 102. The drop rock 105 is prefabricated with concrete with a size of 250*400*150 mm, and the lower part is 200 mm from the ground. It is used to stabilize the hanging basket 102, prevent the hanging basket 102 from shaking, and enhance the stability of the device.

[0029] Preferably, two symmetrical holes 100a are opened on the surface of the floor slab 100. After the reinforcement of the floor slab 100 is tied and before the concrete is poured, JDG pipes are used for pre-embedding, and the same reinforcement is used on all sides for reinforcement. The holes 100a are drilled at fixed positions of the floor slab 100 with a hole diameter of 20 mm to prevent the holes from being displaced and the concentricity from being insufficient. The holes 100a can be designed according to the required positions of the holes 100a. This structural system presets corresponding holes 100a at corresponding positions, and the cut should be calculated to meet the structural safety requirements to ensure that the hanging basket 102 suspended from the bottom can cover the entire construction work surface.

[0030] Before construction, the staff needs to conduct a detailed survey of the corridor construction site to understand the length, span, height and whether there is a supporting structure of the corridor, identify potential safety risks such as falling from height and being hit by objects, and formulate corresponding safety measures. After determining the installation position of the hanging basket 102, a hole 100a is opened at the corresponding position on the surface of the floor 100, and then, according to the position of the hole 100a, the suspension component 101 is fixedly installed above the floor 100, and the locking component 103 is installed on the suspension component 101 and the hanging basket 102 is hung to fix the position of the suspension component 101, thereby improving the safety of the entire device.

[0031] Example 2

[0032] Reference Figure 2 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment can lift the hanging basket on the bracket through the first steel wire rope and the second steel wire rope, so that the hanging basket is located below the floor slab, making it convenient for workers to carry out construction below the large-span corridor.

[0033] Specifically, the suspension assembly 101 includes a bracket 101a fixedly connected to the surface of the floor 100. The bracket 101a has a semi-industrial structure and is made of 100*100*5mm square steel, which is welded and assembled according to fixed dimensions to fix and support the entire suspension assembly 101.

[0034] Furthermore, the bracket 101a is provided with a first steel wire rope 101b and a second steel wire rope 101c. The first steel wire rope 101b and the second steel wire rope 101c are both composed of a working steel wire rope, a safety steel wire rope and a reinforcing steel wire rope. A special galvanized steel wire rope is used to connect the bracket 101a and the hanging basket 102. The lower part is connected to the falling rock 105 to ensure stability. The structure of the first steel wire rope 101b and the second steel wire rope 101c is 4×31SW+FC with a diameter of 8.3mm, which is the best choice based on cost, practicality and safety.

[0035] Preferably, the first steel wire rope 101b passes through one of the holes 100a, and the second steel wire rope 101c passes through the other hole 100a. The first steel wire rope 101b and the second steel wire rope 101c extend downward from the hole 100a, and the hanging basket 102 is installed at the lower part. After the installation is completed, micro-expansion concrete higher than the floor slab is used to fill the hole to ensure that the installation is firm. One end of the first steel wire rope 101b and the second steel wire rope 101c pass through the hole 100a and are fixedly connected to the symmetrical positions on both sides of the hanging basket 102, so that the force on both sides of the hanging basket 102 is balanced, thereby increasing the stability and safety of the hanging basket 102.

[0036] The first steel wire rope 101b and the second steel wire rope 101c pass through the hole 100a, and the construction process ensures that the hanging basket 102 can cover all construction areas and meet the structural safety requirements. At the same time, it is fixedly connected to the bracket 101a welded and installed on the upper surface of the floor slab 100. The hoist mounting frames are installed at both ends of the hanging basket 102, and the front, rear and rear guardrails of each basic section are adjusted so that they are as straight as possible. Then, the hoist is placed upright on the ground and installed on the hoist mounting frame. The nuts on all connecting bolts are tightened so that the hanging basket 102 can cover all areas that need to be constructed. The installation position should ensure the stability of the hanging basket to avoid overturning or falling.

[0037] Example 3

[0038] Reference Figure 1 This is the third embodiment of the present utility model. Different from the previous embodiment, in this embodiment, the entire device is protected for safety by a locking assembly to avoid accidents during the use of the hanging basket without protective measures.

[0039] Specifically, the locking assembly 103 includes a lock spiral buckle 103a that is slidably connected to the end of the first steel wire rope 101b or the second steel wire rope 101c away from the hanging basket 102. Four identical lock spiral buckles 103a are slidably connected to the first steel wire rope 101b, and four identical lock spiral buckles 103a are slidably connected to the second steel wire rope 101c. The lock spiral buckle 103a is used to prevent the first steel wire rope 101b or the second steel wire rope 101c from sliding down to avoid causing safety problems.

[0040] Furthermore, the locking turn buckle 103a fixes the end of the first wire rope 101b away from the hanging basket 102 to the middle of the first wire rope 101b, and the locking turn buckle 103a fixes the end of the second wire rope 101c away from the hanging basket 102 to the middle of the second wire rope 101c, thereby increasing the safety of the first wire rope 101b or the second wire rope 101c.

[0041] Preferably, an upper limit position 103b is fixedly connected to the surface of the floor 100 and located at the periphery of the first steel wire rope 101b and the second steel wire rope 101c. The upper limit position 103b is an ultra-high limit stop, which is installed and fixed 80 cm away from the top of the bracket 101a. When the hanging basket 102 is lifted, the limit switch installed on the safety lock touches the upper limit block, which can stop the hanging basket from rising and ensure construction safety.

[0042] The hanging basket 102 is placed on the ground, and the first steel wire rope 101b is passed through the pre-drilled hole 100a away from the hanging basket 102 to ensure that the hanging basket 102 can cover all construction areas and meet the structural safety requirements. It is fixedly connected to the welded and installed bracket 101a, and the locking assembly 103 is installed and fixed at the same time. After the installation is completed, debugging and inspection are carried out to ensure the normal operation of the hanging basket 102, and static load tests are carried out to ensure that the overall force-bearing operation state of the hanging basket 102 is in good condition. Before each use, check whether the working platform, hoist, suspension mechanism and other components of the hanging basket 102 are intact. Operator requirements: The operator of the hanging basket 102 must undergo technical training and be qualified, and be certified to work. The use of the hanging basket 102 must not exceed the rated load, including personnel and materials.
