[0014] The novel precision steel alloy curtain wall installation method of the present invention comprises the following steps: 1. Column design Please refer to Figure 1 and Figure 2 The column specifications are 120×60×3mm thick precision steel profiles (surface powder sprayed), which are processed in the factory through cold rheology precision forming technology and then loaded into the site.

[0015] 2. Column installation method The installation of the main keel column 1 of the curtain wall is to be installed from the bottom of the concrete structure 13 upwards, and it can be carried out after the installation and verification of the embedded parts are completed. Before the installation of the precision steel square tube, the post-embedded plate 14 is installed. The post-embedded parts are fixed with 300×200×10mm thick (hot-dip galvanized steel plate on the surface) through 4 M12×160mm thick chemical bolts 15. The diameter of the M12 bolt hole is 14mm, and the hole depth shall not be less than 110mm. The curtain wall keel is installed with 100×63×8mm thick angle iron connectors, and is connected with the embedded parts by continuous welding. The 120×60×3mm thick precision steel profile (surface powder coating) is used as the main keel column 1. The 4mm thick and 250mm long steel insert 18 is pre-inserted into the main keel, and the column is connected with the angle iron 16 connector by continuous welding with 2 M12×120mm thick stainless steel bolt assemblies 17 and steel gaskets 21. There is a column on each floor with two points. The columns are hoisted, and the upper and lower columns are connected by core sleeves. The upper and lower columns can be freely expanded and contracted, and the expansion joints are treated with glue.

[0016] 3. Beam installation method Figure 3 This is a side view of the installation of the beam node of an embodiment of the present invention. Figure 4It is a top view of the connection node between the column and the beam of the embodiment of the present invention. First, fix the three-hole beam insert 4 and the beam 2 together with M5×20mm stainless steel screws, use the positioning plate to drill holes on the column where it is connected to the beam, and pay attention to the coaxiality of the drilled holes to ensure the accuracy of the height of the beams on both sides of the column. When installing the insert, one end should be closed with stainless steel bolts and other materials, and the other end should be equipped with a stainless steel spring pin (first insert the spring into the hole, then insert the steel pin into the hole with the spring, and check and press repeatedly several times to avoid the steel pin from getting stuck), and then three pins with springs (pin size φ 8×50mm long), twist it counterclockwise into the pin hole of the curtain wall beam until the pin is inserted into the remaining pin hole, determine the position of the beam to be installed on the column, and then retract the spring steel pin to the position flush with the surface of the beam core tube, push the beam horizontally and flush between the columns on both sides until the spring pin enters the reserved hole of the column (the installation of the beam is completed when the core is in place and the "click" sound is heard. , and sealant strips are inserted into the columns and beams, and then the push pins are pushed into the corresponding holes, and glue is applied to the connection of the spring pin 3 to fix it.

[0017] The installation methods of the components used in the present invention, such as the single-sided sticker 5, double tempered insulating glass 6, EPDM rubber strip, sealing strip 7, aluminum alloy pressure plate 8, EPDM pad 9, aluminum alloy buckle cover 10, M6*55 stainless steel hexagon head bolt group 11, aluminum alloy glass support code 12, and Et plate 19, are all prior arts and are well known to technical personnel in the industry, so their specific structures, performances and other parameters are not described in detail.

[0018] The present invention has substantial characteristics and significant technical progress. The novel precision steel alloy curtain wall installation method of the present invention is a curtain wall installation process using a novel precision steel alloy as a main keel, which can provide a product with simple construction, good fire resistance, high rigidity, stable welding performance, beautiful products, and especially high tensile strength, which is suitable for use in glass curtain walls in coastal cities and is a new material with reasonable structural stress.

[0019] Precision steel has a small deviation in profile size and can achieve the extreme thinness of the outer R angle. By using cold and hot crystal rheology technology to ensure that the R angle of the profile is intact and full, the aesthetics of the product is greatly improved. The precision steel adopts a tensile force structure to bear force, which greatly improves the safety of the glass curtain wall. With global warming, high-level typhoons appear more frequently. When the continuous positive and negative wind pressure is strong, the precision steel alloy profile curtain wall system will greatly make up for the shortcomings of building safety. Compared with aluminum alloy profiles, precision steel profiles have high strength and high rigidity. Steel profiles can support larger spans of partitions, and have better high temperature resistance and corrosion resistance. The energy consumption of precision steel profile processing is low, which is more in line with the current national overall policy of low-carbon environmental protection and green energy saving. Compared with the traditional aluminum alloy glass curtain wall system, the use of precision alloy steel glass curtain wall system has lower production pollution, stronger tensile force, greater structural strength and low expansion. The unique cross-sectional structure of precision alloy steel profiles allows the entire structural system to have a larger span, with less steel used per unit area; fewer system parts, more convenient construction, and more material savings; due to the characteristics of precision steel raw materials, compared with traditional aluminum alloy curtain walls, it has a stronger load-bearing capacity, stronger wind resistance, better fire resistance, and higher safety in use; and can reduce construction costs, reduce construction difficulty, and shorten construction period while ensuring construction quality.
