Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0017] The present invention provides a multi-dimensional torsional hyperbolic curtain wall installation structure, comprising a main steel structure, a main steel structure and an exterior wall connection, characterized in that: welded channel steel is fixed to the side of the main steel structure, a galvanized steel tube is fixed to the other end of the welded channel steel, the galvanized steel tube is detachably connected to the cast aluminum circular chassis, and the two have installation adjustment margins in the Y-axis direction, an adapter connecting plate is detachably installed on the back of the cast aluminum circular chassis, and there are adjustment margins along the X-axis, the Z-axis and around the Y-axis between the two, L-shaped aluminum adapters are hinged at both ends of the adapter connecting plate, the L-shaped aluminum adapter plate can rotate around the Z-axis, a bent steel plate is installed on the L-shaped aluminum adapter, and there is an adjustment margin around the X-axis between the two, and the tail end of the bent steel plate is rotatably connected to the curtain wall module.

[0018] The installation method of the above-mentioned multi-dimensional torsion hyperbolic curtain wall installation structure is as follows:

[0019] Step 1: Early BIM model adjustment and processing preparation

[0020] The main steel structure of the building was re-measured to collect its actual spatial coordinates, elevation and plane position data. The re-measured data was imported into the BIM system and compared with the design model to analyze deviations.

[0021] The order size of each curtain wall module is precisely adjusted based on the deviation data. For non-standard-sized curtain wall modules, the BIM model is used to simulate cutting and blanking to ensure that the processing accuracy meets the requirements of multi-dimensional torsional hyperbolic modeling.

[0022] Step 2: Installation of main steel structure and foundation connectors

[0023] Pretreatment of the main steel structure: Clean the side connection area of ​​the main steel structure to ensure that the surface is flat and free of impurities; weld sealing steel plates on the side of the main steel structure according to the designed position to enhance the stability of the connection.

[0024] Installation of welded channel steel: Weld one end of the welded channel steel to the side of the main steel structure. Use symmetrical welding process to reduce deformation during welding. Perform flaw detection after welding to ensure weld quality.

[0025] Galvanized steel channel connection: Fix the other end of the galvanized steel channel to the welded channel steel (bolt connection or welding can be used according to design requirements). After installation, check its verticality and position deviation to ensure that it meets the design benchmark.

[0026] Step 3: Installation of transfer system and adjustment of curtain wall modules

[0027] Installation of cast aluminum round chassis: Insert the double-wing connecting plate of the cast aluminum round chassis into the end of the galvanized steel tube and fix it with bolts; use the waist holes on the double-wing connecting plate to adjust the position of the galvanized steel tube along the Y-axis direction (adjustment margin 20mm), and tighten the bolts after adjusting it into place.

[0028] Adapter plate installation: Fasten the adapter plate to the back of the cast aluminum round chassis with bolts. Utilize the waist hole structure of both to adjust the position along the X-axis and Z-axis (with 20mm adjustment margin for each), and rotate around the Y-axis to adjust the angle. Tighten the bolts after adjustment.

[0029] Connect the L-shaped aluminum adapter to the bent steel plate: Hinge the ends of the L-shaped aluminum adapter to the adapter connecting plate (allowing it to rotate about the Z axis); secure the bent steel plate to the L-shaped aluminum adapter using an M6x25 bolt assembly. Screw the bolts onto serrated square washers, which engage with the anti-slip teeth on the inside of the L-shaped aluminum adapter to prevent loosening, while retaining rotation adjustment margin about the X axis.

[0030] Curtain wall module hoisting and fine-tuning: The curtain wall modules are hoisted according to the BIM planning sequence and temporarily fixed to the end of the bent steel plate. The settlement, deformation and error data of the steel skeleton are collected and imported into the BIM system. The errors are resolved through the following methods:

[0031] Y-axis deviation: adjust the fit between the cast aluminum round chassis and the waist hole of the galvanized steel pipe;

[0032] X / Z axis deviation: adjust the waist hole position of the cast aluminum round chassis and the adapter connecting plate;

[0033] Torsion angle deviation: Corrected by rotating the L-shaped aluminum adapter around the Z axis, the bent steel plate around the X axis, or the cast aluminum round base around the Y axis.

[0034] Final fixation and sealing: After precision adjustment, tighten all bolts and fill sealant in the connection gap between galvanized steel tube and cast aluminum round chassis, and in the contact area between curtain wall module and bent steel plate to ensure sealing and waterproofness.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
