Description

[0002] With the rapid development of the economy, urban residents have higher and higher requirements for the facades of office buildings, and people have higher and higher requirements for the beauty and comfort of buildings. Architects have begun to combine doors and windows with curtain walls in super-high-rise residential building projects, and adopt systematic design for residential doors and windows, pursuing large glass floor-to-ceiling visual effects. In recent years, the architectural design of some high-end projects often adopts the combination of curtain walls with peculiar facade shapes and system doors and windows to create a more beautiful and comfortable high-rise building design. At the same time, the design of super-large glass system windows has brought a series of unprecedented challenges to the construction of curtain walls. How to quickly and accurately hoist and install super-large glass system windows has become a new problem in the construction process. At present, the super-large glass system windows are usually pulled into the construction elevator according to the size of the construction elevator during the construction process. Glass and aluminum profiles are then transported to the corresponding floor and then moved to the corresponding installation position. Due to the limited size of the construction elevator, when the system window that is too large cannot be placed, it is necessary to divide the entire system window into two parts for easy transportation, and then connect the two parts of the glass window to each other during installation. However, the system window divided into two parts not only destroys the integrity of the super-large system window, but also makes the sealing and aesthetics of the system window worse.

[0003] Therefore, there is an urgent need for a transportation and hoisting construction method that does not require the segmentation of the oversized system windows. Summary of the invention

[0031] like Figure 1 and Figure 2 As shown, the present invention provides a BIM-based system window hoisting construction method, which is used for the hoisting of super-large door windows and doors, and the BIM-based system window hoisting construction method includes the following steps:

[0032] S1. Modeling: Establish a three-dimensional information model of the construction building based on the BIM system;

[0033] S2, model review: measure the construction building and review the dimensional data of the three-dimensional information model established in step S1;

[0034] S3, model correction: According to the three-dimensional information model reviewed in step S2, correct the model structure with deviations;

[0035] S4. Fixing doors and windows: Fix the doors and windows for hoisting in the keel frame;

Door and window hoisting: A hoisting point is provided on one side of the construction building, and the center of gravity of the door and window 1 to be hoisted is located on the hoisting point. A lifting mechanism 3 is provided on the floor to be installed of the construction building. The output end of the lifting mechanism 3 is collinear with the center of gravity of the door and window 1 to be hoisted through a pulley mechanism so that the door and window 1 to be hoisted can be translated to the floor to be installed. A traction mechanism is provided at the bottom end of the door and window 1 to be hoisted so that the door and window 1 to be hoisted can be moved horizontally into the building floor.

[0037] S6. Fixing doors and windows: After the hoisted doors and windows 1 are transported to the building floor, they are fixed and installed in the reserved window openings of the building floor.

[0038] In this embodiment, the BIM-based system window hoisting construction method, through the coordinated setting of the lifting points, the lifting mechanism and the pulley assembly, makes it possible to hoist extra-large system doors and windows without dividing the large-sized system doors and windows, thereby avoiding affecting the design effect of the large-sized system doors and windows, ensuring the quality of the installation, and improving the efficiency of the construction.

[0039] In step S5, the lifting mechanism 3 includes a winch, which is fixedly installed on the floor of the to-be-installed floor, and is connected to the door and window 1 to be hoisted via a pulley mechanism. In this embodiment, by arranging the winch on the floor to be installed, the output end of the winch is connected to the door and window 1 to be hoisted via a pulley mechanism, so that the door and window 1 to be hoisted can be stably lifted vertically.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, the pulley mechanism in step S5 includes a first fixed pulley 21 and a second fixed pulley 22, and the lifting mechanism 3 is connected to the doors and windows 1 to be hoisted through the first fixed pulley 21 and the second fixed pulley 22 one by one, the first fixed pulley 21 is fixedly arranged in the floor to be installed and connected to the inner wall of the reserved window opening, and the second fixed pulley 22 is fixedly arranged above the doors and windows 1 to be hoisted and is colinear with the center of gravity of the doors and windows 1 to be hoisted.

[0041] The pulley mechanism includes a bracket assembly 4 for fixing the second fixed pulley 22, and the bracket assembly 4 is fixedly arranged on the upper floor of the floor to be installed. The bracket assembly 4 includes a fixing part and a bracket body 41, and the bracket body 41 is fixedly connected to the floor. The first end of the bracket body 41 is located in the floor, and the second end of the bracket body 41 extends out of the floor and is located above the door and window 1 to be hoisted. The first end and the second end of the bracket body 41 are fixedly arranged with fixing parts, and the fixing parts are fixedly connected to the construction building.

[0042] In one embodiment, the fixing member includes a first fixing combination or a second fixing combination; under different construction conditions, different fixing combination schemes are used to hoist doors and windows at different floor positions, and the hoisting schemes are as follows:

[0043] like Figure 2 As shown, when the bracket body 41 is set between floors of the construction building, the first fixing combination includes a fixing rod 42 and a fixing rope 43, the first end of the bracket body 41 is fixedly provided with the fixing rod 42, the fixing rod 42 is fixedly connected to the floor, one end of the fixing rope 43 is fixedly provided at a building floor higher than the bracket body 41, the other end of the fixing rope 43 is connected to the second end of the bracket body 41 to fix the bracket body 41, and a second fixed pulley 22 is fixedly provided at the bottom of the second end of the bracket body 41; in this embodiment, when the floor to be installed with doors and windows is n floors, the bracket body 41 is set on the n+1th floor of the construction building, and one end of the fixing rope 43 is fixedly provided on the n+2th floor.

[0045] In the above-mentioned embodiment, the super-high-rise and super-large system window hoisting construction method uses the setting of a pulley mechanism so that the wire rope from the winch can change the direction of the external force applied by the winch through the pulley mechanism, so that the door and window 1 to be hoisted can be quickly and stably lifted to the floor to be installed under the action of the winch.

[0046] In a preferred embodiment, in step S5, the bottom end of the door and window 1 to be hoisted is connected to a guy rope for dragging the door and window 1 to be hoisted.
