Description

Technical Field

[0001] This invention relates to the field of curtain wall installation technology, and more specifically, to a construction method for a diamond-shaped curtain wall for ultra-high-rise buildings. Background Technology

[0002] As people's living standards improve, their pursuit of spiritual fulfillment also becomes more sophisticated. High-end, multi-functional public buildings are increasingly entering people's lives, boasting unique designs. Besides meeting structural safety and functional requirements, these buildings also demand high-end, grand, and classy facades. In addition to basic structural, insulation, and energy-saving requirements, they also demand grandeur, aesthetics, and classiness, such as concert halls, museums, and office buildings. This type of building features novel and unique shapes, complex structures, harsh surrounding environmental conditions, and significant construction challenges. Traditional construction techniques face the following problems when dealing with multi-folded diamond-shaped super high-rise buildings: 1. For the keel used in super high-rise buildings, the keel support can usually only be installed section by section at high altitude, which increases the amount of high-altitude work, raising the construction difficulty and workload; 2. When dealing with glass curtain walls located on different planes within the diamond shape, high-altitude installation is inconvenient, requiring repeated adjustments to the installation position of the suspended platform.

[0003] Therefore, there is an urgent need for a diamond-shaped curtain wall construction method that eliminates the need for repeated adjustments to the suspended platform installation position, reduces high-altitude operations, and lowers construction difficulty. Summary of the Invention

[0004] The purpose of this invention is to provide a construction method for a diamond-shaped curtain wall on a super high-rise facade. The construction method for a diamond-shaped curtain wall on a super high-rise facade provided by this invention modularizes the main keel, allowing the keel support to be pre-assembled on the ground and then transported to the air for installation, reducing the time spent on high-altitude operations. Furthermore, the installation mechanism settings for different construction sections enable the suspended scaffold to install glass curtain walls at different entry and exit points.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A construction method for a diamond-shaped curtain wall on a super high-rise facade, the method being used for the installation of a diamond-shaped glass curtain wall, wherein the diamond shape includes a glass curtain wall and main keels and vertical keels for supporting the glass curtain wall, the main keels and vertical keels being fixedly connected to the building under construction, characterized in that the construction method for the diamond-shaped curtain wall on a super high-rise facade includes the following steps:

[0007] S1. Modeling: Establishing a three-dimensional information model of the building under construction using the BIM system;

[0008] S2, Model Verification and Correction: The construction building is scanned and measured using a 3D scanner to verify the 3D information model established in step S1 and correct any deviations in the model structure.

[0009] S3. Vertical keel installation: Using a total station to locate the pre-set installation points on the construction building, fix the vertical keel to the construction building;

[0010] S4. Main keel installation: The main keel includes multiple interconnected keel brackets. All of the multiple keel brackets are fixedly connected to the construction building. Each of the keel brackets is prefabricated and assembled at the processing site.

[0011] S5. Curtain wall installation in the first construction section: The construction building is divided into multiple construction sections according to its height. Assuming that the first construction section is from the first floor to the Nth floor, a protective mechanism is set up at the N+3 floor of the construction building, and a curtain wall installation mechanism is set up at the N+2 floor to install the curtain wall on the floors of the first construction section.

[0012] S6. Installation of curtain walls in other construction sections: For other construction sections, the glass curtain wall is installed near the construction building using the installation mechanism. The installation mechanism can move to the top of the construction building away from the exterior wall of the construction building to fix and seal the glass curtain wall.

[0013] Preferably, in step S4, the keel support includes multiple pairs of intersecting steel supports, with adjacent steel supports connected to each other.

[0014] Preferably, in step S4, the width of the keel support does not exceed one-quarter of the width of the diamond-shaped structure of the construction building, and the height of the keel support does not exceed the height of two floors of the construction building.

[0015] Preferably, the installation mechanism in step S5 includes a lifting assembly and an installation basket, the lifting assembly is fixedly installed on the construction building, and the installation basket is connected to the output end of the lifting assembly.

[0016] Preferably, in step S5, the installation basket is located outside the diamond-shaped structure of the construction building, and the distance between the installation basket and the exterior facade of the construction building is equal to the length of the highest entry / exit position. In step S6, the installation basket is located outside the diamond-shaped structure of the construction building, and the distance between the installation basket and the exterior facade of the construction building is equal to the length of the highest entry / exit position plus 1 meter.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] like Figure 1 and Figure 2 As shown, this invention provides a construction method for a diamond-shaped curtain wall on a super high-rise facade. This method is used for the installation of diamond-shaped glass curtain walls. The diamond shape includes a glass curtain wall and main keels and vertical keels 2 for supporting the glass curtain wall. Both the main keels and vertical keels 2 are fixedly connected to the building under construction. The method is characterized by the following steps:

[0031] S1. Modeling: Establishing a three-dimensional information model of the building under construction using the BIM system;

[0032] S2, Model Verification and Correction: The construction building is scanned and measured using a 3D scanner to verify the 3D information model established in step S1 and correct any deviations in the model structure.

[0033] S3. Vertical keel installation: Using a total station to locate the pre-set installation points on the construction building, fix the vertical keel 2 onto the construction building;

[0034] S4. Main keel installation: The main keel includes multiple interconnected keel brackets 11. All multiple keel brackets 11 are fixedly connected to the construction building. Each keel bracket 11 is prefabricated and assembled at the processing site.

[0035] S5. Curtain wall installation in the first construction section: The construction building is divided into multiple construction sections according to its height. Assuming that the first construction section is from the first floor to the Nth floor, a protective mechanism is set up at the N+3 floor of the construction building, and a curtain wall installation mechanism is set up at the N+2 floor to install the curtain wall on the floors of the first construction section.

[0036] S6. Curtain wall installation in other construction sections: For other construction sections, glass curtain walls close to the construction building are installed using an installation mechanism. The installation mechanism can move to the top of the construction building away from the exterior wall to fix and seal the glass curtain wall.

[0037] In this embodiment, the building facade is designed to resemble a diamond shape through the connection of glass curtain walls at different angles. Since the diamond shape has outward-protruding and inward-recessed planes, traditional curtain wall installation methods often require repeated adjustments to the position of the installation scaffold in the installation mechanism to accommodate the farthest protrusion and inward-recessed points of the diamond shape. This significantly increases the difficulty and complexity of construction and the workload of construction workers. Therefore, this invention proposes a diamond-shaped curtain wall construction method. Based on the height of the building, BIM is used to simulate the building, dividing it into sections. The installation methods for the first and other sections are modularly managed. The installation scaffold for the first section is positioned at the farthest protrusion point of the diamond shape, while the installation scaffolds for other sections are positioned 1 meter away from the farthest protrusion point. This eliminates the need to move the installation scaffolds when installing glass curtain walls at different entry / exit positions, allowing for sequential installation from bottom to top. In the case of super high-rise building construction, the main keel often spans multiple floors. If the various supports of the main keel are directly installed at high altitude, it will undoubtedly greatly increase the workload. Therefore, in this construction method, the main keel is divided into sections, and each section of the keel support 11 is pre-assembled and installed on the ground. Then, each section of the keel support 11 is transported as a whole to the exterior facade of the building for installation.

[0038] like Figure 2 As shown, in step S4, the keel support 11 includes multiple pairs of intersecting steel supports, with adjacent steel supports connected to each other. In step S4, the width of the keel support 11 does not exceed one-quarter of the width of the diamond-shaped structure of the construction building, and the height of the keel support 11 does not exceed the height of two floors of the construction building.

[0039] In this embodiment, the keel support 11, after being modularized from the main keel, is pre-assembled on the ground and then transported as a whole to the exterior of the building for installation. This avoids the long construction time and difficulty in controlling the construction quality caused by directly installing each steel support in the traditional construction process.

[0040] In a preferred embodiment, the installation mechanism in step S5 includes a lifting assembly and an installation basket. The lifting assembly is fixedly mounted on the construction building, and the installation basket is connected to the output end of the lifting assembly. In step S5, the installation basket is positioned outside the diamond-shaped structure of the construction building, and the distance between the installation basket and the exterior facade of the construction building is equal to the length of the highest entry / exit position. In step S6, the installation basket is positioned outside the diamond-shaped structure of the construction building, and the distance between the installation basket and the exterior facade of the construction building is equal to the length of the highest entry / exit position plus 1 meter. The length of the highest entry / exit position is the distance between the farthest outward protrusion point and the farthest inward concavity point of the diamond-shaped structure. The lifting assembly includes a lifting component and a translating component. The lifting component is fixedly mounted inside the construction building, and its output end is connected to the installation basket. The translating component is located inside the installation basket and allows the installation basket to move horizontally in the lateral direction to accommodate the protrusions and concavities of the diamond-shaped structure of the construction building.

[0041] In this embodiment, the lifting component is preferably a lifting motor, and the translation component is preferably a connecting belt with a locking connector at one end. The locking connector of the connecting belt is engaged with the steel column of the building. Through the action of external force, the installation basket can move horizontally to adapt to the installation of glass curtain walls on the protrusions and depressions of the building's diamond-shaped structure.

[0042] In a preferred embodiment, the protective mechanism includes a protective shed and a suspended platform; the suspended platform is connected to the construction structure to hold the installation mechanism when not in operation, and the protective shed is connected to the construction structure. The protective shed effectively prevents objects from falling from heights during high-altitude operations, improves the safety of construction work, and avoids injuries from falling objects.

[0043] In one embodiment, the glass surface inside the diamond-shaped recess of the super high-rise facade diamond-shaped building is 1.5 meters away from the highest point of the diamond-shaped structure. Firstly, since the main keel spans multiple floors, considering that installing each keel directly would be time-consuming and of low quality, the keel support 11 is assembled on the ground processing site. For ease of hoisting, the width of the keel support 11 is selected to be 1 / 4 of the width of the diamond-shaped structure, and the height is selected to be 2 times the height of the diamond-shaped structure. It is then transported to the corresponding floors for installation, which improves efficiency and ensures installation quality. Secondly, according to the schedule, floors 1-21 are the first construction section, and a protective shed and suspended platform are erected on the 24th floor. In the first construction section, a suspended platform is installed on the 23rd floor. In the construction section above the 23rd floor, the installation position of the suspended platform is extended to 2.5m. The platform is placed on the ground and the glass panels are installed. For the first construction section below the 23rd floor, the suspended platform of the 23rd floor is first fixed 1.5m away from the exterior facade of the building, and the glass panels are installed from bottom to top. Then, when encountering glass in the groove on the same vertical line, the platform is pulled closer by hooking the steel column with a clamp and then the platform is secured with a connecting strap for the installation of the glass panels. Finally, in the second construction section above the 23rd floor, the conventional glass curtain wall near the interior is first installed using a suspended platform, and then the platform is moved outward to a position where the highest glass curtain wall can be installed.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
