[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] like Figure 1 As shown, the embodiment of the present application provides an installation method of a hyperbolic curtain wall system based on a five-dimensional adjustable claw, comprising the following steps:

[0044] Step 1: Use BIM technology to build the curtain wall unit BIM model.

[0045] Step 2: Perform curvature analysis, parameterization analysis and shape analysis on the curtain wall unit BIM model to obtain the overall BIM model of the hyperbolic curtain wall.

[0046] Step three, close-molding the overall BIM model of the hyperbolic curtain wall to obtain a hyperbolic curtain wall system installation model.

[0047] Step 4: performing an installation process according to the installation model of the hyperbolic curtain wall system. In the installation process, a five-dimensional adjustment claw is used to perform five-dimensional adjustment on the position and angle of the curtain wall unit.

[0048] Exemplarily, step one includes: extracting the surface UV lines of the curtain wall unit using BIM technology, grouping them according to odd and even numbers, and arranging the units to obtain the curtain wall unit BIM model.

[0049] Specifically, in this embodiment, the GRASSHOPPER design plug-in in the Rhino environment of BIM technology is used for layout design, the surface UV lines of the curtain wall units are extracted, and the units are grouped according to odd and even numbers. The odd group is arranged according to the curtain wall unit modulus, and the even group is arranged according to the curtain wall unit modulus after reserving half the distance of the curtain wall unit modulus at the top, so as to achieve the staggered effect. Figure 2 Shown is a Rhino modeling schematic of the curtain wall unit BIM model.

[0050] Exemplarily, in step 2, the curvature analysis includes: using different colors to represent different curvatures, and adjusting the curtain wall unit modulus according to the transition of the curvature.

[0051] The parametric analysis includes: setting material parameters and size parameters in the curtain wall unit BIM model according to performance requirements.

[0052] The shape analysis includes: setting the shape of the curtain wall unit in the curtain wall unit BIM model according to the shape appearance requirements.

[0053] like Figure 3 The figure shows a schematic diagram of curvature analysis of the curtain wall unit BIM model. Specifically, in this embodiment, through curvature analysis, it is found that when the curtain wall unit modulus is 1800mm, the curtain wall unit has obvious edges and corners and is not smooth when transitioning in the red area. After many studies and optimizations, the curtain wall unit modulus is adjusted to 1100mm, thereby successfully achieving a smooth transition of the red part, making the appearance of the entire curtain wall system more beautiful and smooth.

[0054] Specifically, in this embodiment, through parametric analysis and four sample demonstrations, the material parameters of the curtain wall unit system in the curtain wall unit BIM model are set to steel material and the size parameters are set to 6m*17m. The curtain wall unit system with such material parameters and size parameters has higher strength and stability, and can better withstand the deadweight and external loads of the curtain wall.

[0055] Specifically, in this embodiment, the shape of the curtain wall unit in the curtain wall unit BIM model is set to be a sail shape by performing shape analysis. In other possible embodiments, it can also be set to other shapes according to actual morphological appearance requirements.

[0056] Specifically, in this embodiment, an overall BIM model of a LOD400 hyperbolic curtain wall is created, and processing parameters are extracted through the model. The processing parameters are then output in the form of an EXCEL table, so that the BIM model can be truly explained in simple terms, allowing downstream manufacturers to understand the drawings to be processed.

[0057] Exemplarily, step three includes:

[0058] The curtain wall units and the curtain wall supporting structure in the overall BIM model of the hyperbolic curtain wall are integrated and divided into several units. The curtain wall supporting structure adopts a steel structure.

[0059] Create a tire frame model based on the divided units, and distinguish and number the plates of different lengths.

[0060] The overall BIM model of the hyperbolic curtain wall and the frame model together constitute the installation model of the hyperbolic curtain wall system.

[0061] Exemplarily, in step 4, the installation process includes: curtain wall unit hoisting verification, frame positioning, small unit translation, unit profile layout, and curtain wall unit installation.

[0062] Specifically, in this embodiment, a hoisting verification calculation is performed on a curtain wall unit that is 6 meters wide, 17 meters high, and weighs about 20 tons, including a comprehensive verification calculation of the center of gravity, force, and hoisting point position to ensure the safety and reliability of the hoisting process.

[0063] In this embodiment, the tire frame is placed in the corresponding construction area, leveled and fixed. Taking the three-level observation points arranged on the first-floor platform as the reference, the coordinates of each node of the tire frame are measured and entered into the model to generate the tire frame model, providing an accurate reference for subsequent construction operations.

[0064] In this embodiment, the seamless steel tube bracket, connecting rod, seamless steel tube ring beam, sleeve-type seamless steel tube connector, and aluminum alloy support rod are regarded as a small unit as a whole, and accurately translated to the tire frame in the model. The small unit is rotated according to the principle that the surface where the longest arc of the ring beam is coplanar with the tire frame platform surface, and new coordinates of each measurement point are generated to ensure that the installation position of the small unit is accurate.

[0065] In this embodiment, the profile is first marked with a total station before being installed on the unit frame, and then installed independently. In order to avoid factors such as positioning deviation and profile processing deviation affecting the installation quality, the unit profile points must be fully checked and verified on the ground to ensure that the installation position of each profile meets the design requirements.

[0066] In this embodiment, the curtain wall units in the model are precisely positioned by coordinates. During on-site installation, the positioning points of each unit are marked by an intelligent total station, and angle steels are used as support and positioning auxiliary installation to ensure the installation accuracy and stability of the curtain wall unit facade.

[0067] Exemplarily, in step 4, the curtain wall unit installation includes: unit system positioning assembly and curtain wall unit overall hoisting.

[0068] Specifically, in this embodiment, the curtain wall unit is a spatial geometric shape, and the positioning is extremely complex. In order to control the installation accuracy and improve the installation efficiency, the curtain wall unit is divided into a 6m*17m unit system, and the three-level observation points arranged on the first-floor platform are used as the reference, and the total station lofting method is used to perform fixed-point positioning and assembly in sequence. Each unit plate is assembled on the ground, and then hoisted and installed as a whole to ensure the installation accuracy and quality of the entire curtain wall system.

[0069] In this embodiment, the assembled unit is lifted to the installation area by crane, hoist and other equipment, and installed with two aerial platforms. During installation, the bull leg positioning is performed using the total station setting out method with the second-level observation point on the first floor as the reference. The aerial personnel rotate, move and fine-tune the unit according to the precise command of the surveyor, and finally complete the positioning installation.

[0070] like Figure 4 and Figure 5 As shown, exemplarily, in step four, the five-dimensional adjustment claw member includes: a docking head 1, a docking claw arm 2, and a connecting seat 3.

[0071] One end of the docking claw arm 2 is movably connected to the docking head 1 through a bolt 4 and a long hole 5, and the other end is movably connected to the connecting seat 3.

[0072] The connection seat 3 is used for fixed contact with the curtain wall support structure and for adjusting the welding angle.

[0073] The docking claw arm 2 is used for front and rear position adjustment.

[0074] The angle and position of the docking claw arm 2 and the docking head 1 are adjusted through the bolt 4 and the long hole 5 .

[0075] The docking joint 1 is used for fixed contact with the curtain wall unit.

[0076] The curtain wall unit is adjusted in vertical angle by means of two five-dimensional adjustment claws arranged up and down.

[0077] Specifically, in this embodiment, the connection seat 3 can achieve ±90° welding angle adjustment, the docking claw arm 2 can achieve ±30mm front and rear position adjustment, the bolt 4 and the long hole 5 can achieve ±10° angle adjustment and ±15mm position adjustment, and the vertical angle adjustment can be achieved through the different adjustment degrees of the two upper and lower five-dimensional adjustment claws. Thus, the effect of five-dimensional adjustment is achieved to ensure the installation accuracy of the curtain wall unit on the hyperbolic surface.

[0078] Exemplarily, in step four, the five-dimensional adjustment claw is made of stainless steel.

[0079] The embodiment of the present application adopts a five-dimensional adjustment claw to adjust the position and angle of the curtain wall unit in five dimensions, combines BIM technology to optimize the design and installation process, improves the installation accuracy of the curtain wall unit on the hyperbolic surface, reduces errors, and thereby improves the overall quality, safety and aesthetics of the curtain wall system.

[0080] It is proposed to use BIM technology to extract the surface UV lines of the curtain wall unit, group them according to odd and even numbers, and arrange the units to obtain the BIM model of the curtain wall unit, thus achieving the staggered effect.

[0081] The proposed curvature analysis, parametric analysis and shape analysis of the curtain wall unit BIM model improves the appearance smoothness, structural stability and overall aesthetics of the curtain wall unit.

[0082] The proposed five-dimensional adjustment claw comprises: a docking joint 1, a docking claw arm 2, and a connecting seat 3. Combined with bolts 4 and long holes 5, five-dimensional adjustment of the position and angle of the curtain wall unit is achieved, which simplifies the installation process. At the same time, the five-dimensional adjustment has good adaptability to hyperbolic curtain walls with different curvatures and warping conditions, and can flexibly cope with various installation conditions to ensure the stability and reliability of the curtain wall system.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.
