Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0020] This invention achieves its technical objective through the following technical solution: a multi-curved curtain wall unitized frame fabrication and installation device. This device includes a base plate 1, columns 2, curved support beams, a total station (not shown in the figure), and a scanner (not shown in the figure). The column base plate 1 is made of steel plate, the columns 2 are liftable double-steel square tubes, the curved support beams are channel steel, the total station is used to measure the elevation and positioning of the frame fabrication, and the scanner scans the assembled unit frame, comparing its relative position in the designed frame space. Through comparison and analysis of the assembly accuracy, the curvature of each bend meets the design requirements, preparing the segmented frame for hoisting and use.

[0021] Example 1 See Figure 1The present invention utilizes a unitized frame to construct an installation device for a multi-curved curtain wall, including an arc-shaped support beam adapted to the arc shape of the multi-curved curtain wall. Multiple arc-shaped support beams intersect to form a unitized frame. At the bottom of each arc-shaped support beam, multiple columns 2 of different heights are respectively provided according to its arc shape. In this embodiment, the unitized frame has an elliptical arc structure.

[0022] See Figure 2 Each column 2 consists of two steel pipes inserted into each other, and the two steel pipes are connected by fasteners.

[0023] The side wall of the intersecting socket steel pipe 2-1 of the two inserted steel pipes is symmetrically provided with waist-shaped holes. The fastener has a nut 3 welded to one of the waist-shaped holes. The nut 3 is provided with a self-tapping bolt 4 that mates with it. The self-tapping bolt 4 passes through the waist-shaped hole welded to the nut 3 and the inserted steel pipe 2-2 in sequence, reaching the other side of the socket steel pipe 2-1.

[0024] Each column 2 is connected to the curved support beam at its intersection by an adjustable clamp.

[0025] Each column 2 has a base plate 1 at its bottom with a cross-sectional area larger than that of the column 2.

[0026] A total station for measuring and positioning the elevation of the skeleton is installed next to column 2.

[0027] A scanner is installed next to the arc-shaped support beam to scan and analyze whether the curved surface of the arc-shaped support beam meets the curvature design requirements.

[0028] The unitized frame, composed of arc-shaped support beams, is topped with curtain wall frame units arranged according to the curtain wall model. The curtain wall frame units are closely attached to the top surface of the arc-shaped support beams.

[0029] Each curved support beam is made up of multiple smaller curved beams connected together.

[0030] Example 2 See Figure 3 In this embodiment, the modular skeleton has a hyperboloid structure.

[0031] Example 3 The main flowchart of the multi-curved curtain wall unit frame manufacturing and installation method of the present invention is shown in the attached figure. After completing each process, the curtain wall unit can be manufactured and installed.

[0032] See Figure 4 The present invention utilizes a unitized frame to construct an installation method for multi-curved curtain walls, which generally includes the following steps: 1. The skeleton membrane material is manufactured in the factory and then transported to the construction site; 2. On-site measurement and layout of the membrane support pillars to determine their location; 3. Install the membrane support columns and adjust their height to the required elevation for the fabrication of the curtain wall frame unit; 4. Connect each frame onto the membrane support beam one by one to form a whole, and fix it after adjusting the position and elevation; 5. Connect all the frames in place, scan and correct them. After confirming that the dimensions are correct, weld them into shape to complete the fabrication of the first section of the curtain wall frame unit. 6. Proceed with the fabrication of the second section of the curtain wall frame unit. The second section of the curtain wall frame unit is connected and extended to the first section of the curtain wall frame unit. Continue this process until the second section of the curtain wall frame unit is assembled and fabricated. After verification, proceed with the assembly of the third section of the curtain wall frame unit and the fourth section of the curtain wall frame unit to complete the entire petal-shaped curtain wall frame and meet the hoisting requirements.

[0033] Example 4 This embodiment is a further refinement of embodiment 4.

[0034] See Figure 5 The present invention provides an installation method for multi-curved curtain walls using a unitized frame, comprising the following steps: Step 1: Based on the measurement and layout, mark the column positions on the ground, lay the base plate 1, which is larger than the cross-section of column 2, on the hardened ground and fix it. The base plate 1 increases the contact area with the bottom surface to ensure the foundation is stable. Step 2: Install column 2 onto base plate 1 and weld it securely. Adjust the column top elevation by inserting the two steel pipes at the top and bottom. Set oblong holes on both sides of the socket steel pipe 2-1 and the insert steel pipe 2-2. Adjust the position and height of the nut 3 on the outer side of the oblong hole on one side of the socket steel pipe 2-1 to the design elevation, then weld the nut 3. Next, pass self-tapping screws 4 through the oblong hole welded to the nut 3 and through the insert steel pipe 2-2 to the other side of the socket steel pipe 2-1. The specific form is as follows: Figure 1 ; Step 3: Since the curved support beam rests on the top of the column at various elevations, it is bent to form a series of small curved beams. All the small curved beams are connected to form the curved support beam. The support beam is then installed on the top of column 2 to form a unit-type frame. Step 4: Use a total station and a scanner to scan the position of the curved support beam and analyze whether the curved surface of the curved support beam meets the curvature requirements of a single unit frame. If it does not meet the requirements, continue to adjust the column height and the curvature of the support beam until the curvature requirements are met. If it meets the requirements, proceed to the next step of assembling the curtain wall frame unit. Step 5: Weld the curtain wall frame units, which have been laid out according to the curtain wall model, onto the curved support beam. The curtain wall frame units are closely attached to the curved support beam to ensure the curvature requirements are met. Step Six: Use a total station and scanner again to measure and scan whether the curtain wall frame unit meets the design requirements. If it meets the requirements, weld and grind it. If it does not meet the requirements, return to Step Four, apply anti-corrosion and anti-rust paint, and hoist it to the storage yard to produce the next curtain wall frame unit. Step 7: Repeat the installation of the curved support beams and curtain wall frame units until all curtain wall frame units are completed; Step 8: Hoist each curtain wall frame unit onto the roof steel structure purlins. Connect the curtain wall frame units to form an integral curtain wall frame module. Scan and check the quality until a petal is formed, and then install the curtain wall glass profile. Step nine: After the curtain wall glass profiles are installed, install the sub-frames and glass, apply sealant, install the moldings, and complete all construction work on the glass curtain wall.

[0035] Technical features and innovations of this invention: 1) The columns adopt a socket-type design instead of direct welding or a single whole pipe, which can be moved up and down, making it easy to adjust the elevation and ensuring high installation accuracy.

[0036] 2) The entire facade formwork adopts the method of adding (extending) steel columns to extend the assembly length of the tubular truss, which facilitates assembly, allows for large assembly segments, reduces assembly errors, and improves assembly accuracy.

[0037] 3) A total station is used for surveying and setting out, and a 3D laser scanner is used for verification. The 3D laser scanner has a fast verification speed and high accuracy.

[0038] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
