DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] See also Figure 1-6The present invention provides a hanging basket device for a large-area inclined glass curtain wall, which is used for the installation of the glass curtain wall. The hanging basket device for a large-area inclined glass curtain wall comprises a roof grid structure 1 as a main load-bearing structure and a hanging basket assembly arranged on the roof grid structure 1, wherein the roof grid structure 1 is a steel grid structure of a roof system; the hanging basket assembly comprises a lifting rope 4 and a traction rope 3, and the lifting rope 4 and the traction rope 3 connect the roof grid structure 1 with a ground platform 2; the connection between the traction rope 3 and the lifting rope 4 and the roof grid structure 1 is connected by a binding belt 8, and the binding belt 8 is sleeved on the steel frame of the roof grid structure 1, and the connection parts of the binding belt 8, the traction rope 3 and the lifting rope 4 are all circular rings, and the binding belt 8 is connected to the traction rope 3 and the lifting rope 4 by a shackle 9, and the shackle 9 is passed through the ferrule of the binding belt 8 and the traction rope 3 or the binding belt 8 and the lifting rope 4 to complete the connection and fixation of the roof grid structure 1 and the lifting rope 4 and the traction rope 3. The lifting rope 4 is arranged on the left side of the traction rope 3, and the hanging basket body 5 is arranged on the lifting rope 4 and the traction rope 3. The lower end of the traction rope 3 is provided with a fixed pulley 6 for changing the direction of the traction rope 3. The ground platform 2 is also provided with a manual hoist 7 for use with the fixed pulley 6. The manual hoist 7 is used in conjunction with the fixed pulley 6 to adjust the tension and angle of the traction rope 3. The fixed pulley 6 and the manual hoist 7 are both fixed to the ground platform 2 by a rear embedded plate 10 and bolts. The traction rope 3 and the manual hoist 7 are fixed by a shackle 9 and a small ear plate on the rear embedded plate 10. The lifting rope 4 and the traction rope 3 are arranged in parallel during transportation.

[0043] See also Figure 6 Hoists 11 for controlling the lifting of the basket are arranged at both ends of the basket body 5, an electric control box 12 for controlling the operation of the hoist 11 and a safety lock 13 for preventing the basket from accidentally sliding down are arranged above the basket body 5, and the basket is connected to the lifting rope 4 through a connecting device.

[0044] In one embodiment: the hanging basket body 5 adopts a ZLP630 standard hanging basket with a length of 6m, a width of 0.69m, and a height of 1.16m, and the overall deadweight is about 350kg. The construction design load is 1.2kN / m2, which can be operated by 2 people at the same time, and each person is calculated as 100kg, and the actual use load does not exceed 0.3kN / m2.

[0045] The lifting of the basket body 5 requires the vertical upward contraction of the hoist 11, but the basket body 5 can move up and down along the tilt angle, so the basket direction control device 14 is designed above the hoist 11 to realize the direction conversion. The basket direction control device 14 includes two pulleys at the top of the basket body 5 on both sides, the first one is sleeved on the traction rope 3, so that the basket body 5 can be tilted up or down along the inclined glass curtain wall, and the second one is sleeved on the suspension rope, so that the suspension rope can be divided into two sections, the lower section is always parallel to the basket body 5 to ensure safe operation, and the upper section is connected to the roof steel structure to ensure the lifting height of the basket body 5. The traction rope 3 is fixed by a 3t fixed pulley 6 and a 3t manual hoist 7 at the bottom.

[0046] The construction process of the hanging basket is: installing the traction rope 3 and the hanging rope → lifting and installing the hanging basket platform → debugging the hanging basket → normal construction operations.

[0047] Install the traction rope 3:

[0048] Two lifting ropes and two traction ropes 3 are used on each hanging basket platform, all of which are tied and fixed on the roof steel grid structure. After being fixed, they are straightened by manual hoists 7 and hoists 11. The lap length of the wire rope is not less than 24d (d is the diameter of the wire rope). When clamping is used, there are no less than 3 clamps (the diameter of the wire rope ≤ 18mm).

[0049] When the steel wire rope is tied and fixed to the grid ball node, the grid rods are protected by wrapping them with a layer of rubber or aluminum foil to prevent damage to the grid coating layer.

[0050] Lifting and installation of hanging basket platform:

[0051] Two hoists 11 are used at both ends of the hanging basket lifting platform to lift the hanging basket to the required position.

[0052] The parameters for improvement are as follows:

[0053]

[0054] Debugging of hanging basket:

[0055] After the installation work is completed, the installer connects the cable to the electric control box 12 and connects it to the special electric box power supply provided on site. After the staff completes the experiment in the hanging basket, they install the wire rope into the hoist 11 and the safety lock 13. After completing the above work, the hanging basket is raised and lowered 3-5 times, and the height of each rise is about 3m. Then each installer checks the installation of each connection point again, and uses it after inspection and acceptance.

[0056] Normal construction work:

[0057] Before the hanging basket is installed and used, an independent safety rope must be set from the roof steel structure, and a fall arrester must be installed on the safety rope. During construction, construction workers must wear safety belts on the fall arrester on the safety rope to prevent the hanging basket from falling due to a malfunction.

[0058] See also Figure 1-8 , a method for installing a hanging basket for a large-area inclined glass curtain wall, comprising the following steps:

[0059] S1: Install the hanging basket device. After the installation is completed, the hanging basket is hoisted from the outside, and the curtain wall glass 18 is hoisted from the inside;

[0060] S2: The upper ends of the traction ropes 3 are connected to the roof grid structure 1, and the lower ends are connected through the fixed pulley 6 and the manual hoist 7 so that the two traction ropes 3 are straightened and consistent with the inclination of the glass curtain wall;

[0061] S3: adjusting the traction rope 3 through the lifting rope 4 and the hanging basket direction control device 14 to achieve the inclined rise or fall of the outdoor hanging basket body 5 and the indoor inclined glass curtain wall;

[0062] S4: After installing all the panel connectors of the curtain wall within a range of 6m on the hanging basket, lower the hanging basket;

[0063] S5: Tilt the hanging basket up to another area and then lift it up for installation again;

[0064] S6: Repeat the above steps until the construction of the entire area is completed;

[0065] S7: After installation is completed, the platform is dismantled.

[0066] When installing the glass curtain wall outdoors, first install the hanging basket device. After the installation is completed, start synchronous lifting at the same time indoors and outdoors of the curtain wall. First, connect the upper end of the traction rope 3 to the roof grid structure 1, and make the two traction ropes 3 with a diameter of Φ16mm straight and parallel to the inclination of the glass curtain wall through the fixed pulley 6 and the manual hoist 7 below, and then adjust the traction rope 3 through the lifting rope 4 and the hanging basket direction control device 14 to achieve the outdoor hanging basket basket body 5 and the indoor inclined glass curtain wall to rise or fall in an inclined manner; the hanging basket direction control device 14 includes two pulleys arranged on the top of the two sides of the hanging basket basket body 5, the first one is sleeved on the traction rope 3, so that the hanging basket basket body 5 rises or falls along the inclined glass curtain wall, and the second one is sleeved on the hanging rope, so that the hanging rope can be divided into two sections, the lower section is always parallel to the hanging basket basket body 5, and the upper section is connected to the roof steel structure. Then it is hoisted to the specific installation location. After arriving at the location, the curtain wall is installed in the hanging basket 5. The installation range of a hoisting area is 6m. After installing all the curtain wall panel connectors within the 6m range, the hanging basket is lowered, and then moved to another required installation area through the lifting rope 4 and the hanging basket direction control device 14, and then lifted and installed again. Repeat the above operations until the construction of the entire area is completed.

[0067] It should be noted that before the hanging basket is installed and used, an independent safety rope must be set from the roof steel structure, and a fall arrester must be installed on the safety rope. During construction, construction workers must fasten their safety belts to the fall arrester on the safety rope to prevent the hanging basket from falling due to a malfunction.

[0068] When installing the glass curtain wall indoors: the glass is hoisted from indoors, using a winch 19 and two second fixed pulleys 20, so that the glass can be moved vertically and horizontally. A second fixed pulley 6 is placed vertically above the floor slab for the purpose of hoisting the glass plate, and the other second fixed pulley 6 is placed above the outermost side of the inclined glass curtain wall for the purpose of allowing the glass to move parallely. During operation, the glass is first hoisted to a certain position, and then the hook 17 is slowly released. The glass will move outward and downward under the influence of its own weight. Through the tight coordination of the winch 19 and the hook 17, the glass reaches the predetermined position, and then the operator in the hanging basket performs specific positioning and installation.

[0069] After all areas are installed, the platform needs to be dismantled. The platform dismantling process is exactly the opposite of the installation process. The first installed ones are dismantled last, and the last installed ones are dismantled first. The specific process is to first lower the hanging basket hanging basket body 5, then completely loosen the lifting rope 4 and the traction rope 3 to unload, remove the wire rope after unloading, then remove other accessories, and finally clean up the materials.

[0070] During the disassembly process:

[0071] (1) Disassembly must be carried out according to the work process. Special attention should be paid to the fact that it is strictly forbidden to dismantle related accessories before the platform is landed and the wire rope is completely unloaded.

[0072] (2) During the disassembly process, any objects such as tools and accessories must not be thrown. In particular, wire ropes and cables must not be thrown when being dismantled. Instead, they must be held with a strong nylon rope and slowly released from a height and lowered to the ground.

[0073] (3) Warning signs should be set up below the disassembly work, and a designated person should be responsible for supervision.

[0074] (4) If the platform needs to be recycled after disassembly, all accessories must be rechecked.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
