The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] like Figure 1 and Figure 2 As shown, the present invention provides a super high-rise facade diamond body curtain wall construction method, which is used for the installation of the facade diamond body glass curtain wall, the diamond body includes a glass curtain wall and a main keel and a vertical keel 2 for supporting the glass curtain wall, the main keel and the vertical keel 2 are fixedly connected to the construction building, and is characterized in that the super high-rise facade diamond body curtain wall construction method includes the following steps:

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

[0032] S2, model review and correction: Scan and measure the construction building with a 3D scanner, review the 3D information model established in step S1, and correct the model structure with deviations;

[0033] S3, vertical keel installation: using the total station to preset installation points on the construction building, the vertical keel 2 is fixedly installed on the construction building;

[0034] S4. Main keel installation: The main keel includes multiple sections of keel brackets 11 that are connected to each other. The multiple sections of keel brackets 11 are all fixedly connected to the construction building. Each section of the keel bracket 11 is prefabricated and assembled at the processing site;

[0035] S5. Installation of curtain wall in the first construction section: the construction building is divided into multi-layer 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 installed at the N+3th floor of the construction building, and a curtain wall installation mechanism is installed at the N+2th floor to install curtain walls on the floors of the first construction section;

[0036] S6. Installation of curtain walls in other construction sections: For construction buildings in other construction sections, the glass curtain walls close to the construction buildings are installed through the installation mechanism, and the installation mechanism can move toward the side away from the outer wall of the construction building to the top of the construction building to fix and seal the glass curtain wall.

[0037] In this embodiment, the construction building is connected and set at different angles of the glass curtain wall so that the facade of the building appears as a diamond body. Since the diamond body has planes protruding outward and recessed inward, the traditional curtain wall installation method often needs to repeatedly adjust the installation basket position in the installation mechanism to adapt to the farthest protruding point of the diamond body protruding outward and the farthest recessed point of the diamond body recessed inward, which greatly increases the difficulty and complexity of construction and increases the work intensity of construction personnel. Therefore, the present invention proposes a diamond body curtain wall construction method, which uses BIM to simulate the construction building according to the height of the construction building, divides the construction building into sections, and modularizes the installation methods of the first construction section and other construction sections. The installation basket of the first construction section is set at the farthest protruding point of the diamond body protruding outward, and the installation basket of other construction sections is set at 1 meter away from the farthest protruding point of the diamond body protruding outward, so that when installing glass curtain walls with different entry and exit positions, there is no need to move the installation position of the basket, and the glass curtain wall can be installed in sequence from bottom to top. However, in the case of super-high-rise construction, the main keel often crosses floors. If the various brackets 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 the keel brackets 11 of each section are pre-spliced ​​and installed on the ground, and then the keel brackets 11 of each section are transported as a whole to the facade of the building for installation.

[0038] like Figure 2 As shown, in step S4, the keel bracket 11 includes a plurality of pairs of steel brackets cross-connected to each other, and adjacent steel brackets are connected to each other. In step S4, the width of the keel bracket 11 does not exceed a quarter of the width of the diamond body of the construction building, and the height of the keel bracket 11 does not exceed the height of two floors of the construction building.

[0039] In this embodiment, the keel bracket 11 after the main keel is modularized is pre-assembled on the ground and then transported as a whole to the facade of the building for installation, thereby avoiding the traditional construction process of directly installing each steel bracket, which results in long construction time and inconvenient construction quality control.

[0040] In a preferred embodiment, in step S5, the installation mechanism includes a lifting assembly and an installation basket, the lifting assembly is fixedly arranged 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 arranged outside the diamond body of the construction building and the installation basket is equal to the length of the highest entry and exit position from the facade of the construction building. In step S6, the installation basket is arranged outside the diamond body of the construction building and the distance between the installation basket and the facade of the construction building is equal to the length of the highest entry and exit position plus 1 meter, and the length of the highest entry and exit position is the distance between the farthest distance protruding point of the diamond body of the construction building and the farthest distance concave point of the diamond body concave inward. The lifting assembly includes a lifting member and a translation member; the lifting member is fixedly arranged in the construction building, the output end of the lifting member is connected to the installation basket, the translation member is arranged in the installation basket, and the translation member can make the installation basket move horizontally in the lateral direction to adapt to the protrusion and depression of the diamond body of the construction building.

[0041] In this embodiment, the lifting member is preferably a lifting motor, and the translation member is preferably a connecting belt with a clamping joint at one end, and the clamping joint of the connecting belt is clamped with the steel column of the building. Through the action of external force, the installation basket can move horizontally, thereby adapting to the installation of glass curtain walls at the protrusions and depressions of the diamond body of the construction building.

[0042] In a preferred embodiment, the protection mechanism includes a protection shed and a hanging basket parking platform; the hanging basket parking platform is connected to the construction building to park the non-working installation mechanism, and the protection shed is connected to the construction building. The setting of the protection shed can effectively prevent falling objects from high altitude during high-altitude operations, improve the safety of construction operations, and avoid falling objects from injuring people.

[0043] In one embodiment, the glass surface in the diamond body groove of the super high-rise facade diamond body building is 1.5 meters away from the entry and exit position of the highest point of the diamond body; first, the main keel has cross-layers. Considering that it is time-consuming and of low quality to install each one directly, the keel bracket 11 is first assembled at the ground processing site. Based on the convenience of lifting, the width direction of the keel bracket 11 is selected as 1 / 4 of the width of the diamond body, and the height direction is selected as 2 layers of the height of the diamond body for arrangement, and then transported to the corresponding floor for installation, which can not only improve efficiency but also ensure the quality of installation; secondly, according to the schedule, the 1-21 floors are the first construction section, and a protective shed and a hanging basket parking platform are set up on the 24th floor, A hanging basket is installed on the 23rd floor. In the construction sections above the 23rd floor, the installation position of the hanging basket is extended to 2.5m. The hanging basket is parked on the ground. When installing the glass panel, the hanging basket of the 23rd floor is used for the first construction section below the 23rd floor. It is first fixed 1.5m away from the facade of the building, and the glass panel is installed from bottom to top; secondly, for the glass in the groove on the same vertical line, a clamping joint is used to hook the steel column to pull the hanging basket closer, and then the connecting belt is used to hold the hanging basket for the installation of the glass panel; finally, for the part above the 23rd floor of the second construction section, the conventional glass curtain wall close to the indoor part is first installed with the hanging basket, and then the hanging basket is moved outward to the position where the highest point glass curtain wall can be installed.

[0044] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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 only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
