The horizontal steel beam 1 and the steel column 6 constitute the steel structure main body of the building. The steel column 6 is arranged inwardly inclined and is vertically fixedly connected with the horizontal steel beam 1 to provide an installation foundation for the surface aluminum plate curtain wall.

[0021] The fireproof rock wool 2 is located on the outer layer of the steel column 6, fixed in shape by the stainless steel plate 3, and then installed on the steel column 6. The fireproof rock wool 2 is used to achieve fireproofing, heat insulation and heat insulation of the main facade of the steel structure, ensure the energy-saving performance of the aluminum curtain wall, and avoid the rapid spread of fire in the event of a fire, thereby enhancing the practicality of the curtain wall.

[0022] The stainless steel plates 3 are located on both sides of the fireproof rock wool 2, and the shape is cut according to actual needs. They are fixed to the internal built-in longitudinal or transverse angle steels through rock wool fixing nails, providing an installation basis for the fireproof rock wool and realizing the fixation of the fireproof rock wool.

[0023] The horizontal support rod 5 is used to connect the shaped aluminum plate 4 and the steel column 6 , wherein the horizontal support rod 5 and the steel column 6 are connected via an adapter 7 .

[0024] The adapter 7 is fixed on the steel column 6 by welding to support the horizontal support rod 5 and ensure the stability and uniformity of the force on the surface decoration layer.

[0025] A shaped keel is also provided on the inner side of the shaped aluminum plate 4. The shape of the shaped keel is consistent with the outer contour of the shaped aluminum plate 4. It is made by cutting and welding steel rectangular tubes or angle steels and then anti-corrosion. The shaped keel is fixed to the horizontal support rod 5 by welding. An aluminum alloy angle code 8 is installed on the surface of the shaped keel, and the shaped keel is fixedly connected to the shaped aluminum plate 4 through the aluminum alloy angle code 8.

[0026] A construction method for an inward-inclined special-shaped aluminum plate curtain wall with a steel structure main body comprises the following steps:

[0027] Step 1: Measurement and layout. Provide the on-site benchmark control point map for measurement and positioning, measure the steel structure deviation, and determine the installation benchmark after measurement, including the keel arrangement benchmark and the horizontal elevation of each part of the curtain wall, and adjust and control the in and out of the curtain wall in the horizontal, left and right, and up and down directions.

[0028] Step 2: Installation of connectors.

[0029] 1) First, the surveying and layout personnel will mark all the grid lines and elevation lines of the connectors on the steel structure as the reference lines for installing the connectors.

[0030] 2) Install steel connectors according to the center line and grid lines drawn by the layout. The height and left and right of the steel connectors should be controlled within 2 to 3 mm. The steel connectors should be connected to the steel plates by welding using 12# channel steel connectors.

[0031] Step 3: Installation of the modeling keel

[0032] 1) According to the location of the line, the steel frame is installed with the help of a truck crane. The installation is carried out from left to right.

[0033] 2) To ensure the smoothness of the curtain wall facade, first arrange the vertical steel wires at the corners. The construction workers of the layout team pop up the horizontal ink lines between the layers on the bottom plate according to the height dimensions of the construction diagram as the positioning reference line. The installation construction workers use the steel wires as the positioning reference to install the first steel frame.

[0034] 3) Before installing the steel frame, first check the straightness of the central column of the frame by pulling it in. If it does not meet the requirements, correct it before installing it on the wall to control the error within the allowable range.

[0035] 4) Check whether the installation position of the steel frame is correct by comparing it with the construction drawing. Workers use the aerial vehicle as a construction operation platform to weld the steel frame to the steel keel.

[0036] 5) After the steel frame is installed in place, the installation inspection is carried out according to the steel wire arranged by the measurement team and the comprehensive construction drawings. After all dimensions meet the requirements, the verticality of the steel frame is checked to ensure the axial deviation of the steel keel.

[0037] Step 4: Installation of the horizontal keel.

[0038] According to the measured horizontal line of the horizontal steel wire, mark the positioning point on the main keel, weld the crossbeam to the main keel to ensure the installation quality of the crossbeam.

[0039] Step 5: Fireproof rock wool installation.

[0040] First, fix the 1.5mm galvanized steel plate to the main steel structure and the aluminum plate keel with nails and screws respectively, and the overlap of the galvanized steel plate is 30mm. Then install the fireproof rock wool on the steel plate, and install the 200mm thick fireproof rock wool on the galvanized steel plate. The fireproof rock wool is installed densely, with a flat surface and no gaps. The fireproof rock wool is installed in two layers, and the compression ratio of the fireproof rock wool during installation is 1:1.15 (interlayer sealing spacing: rock wool cutting width).

[0041] After the installation is completed, fix the 1.5mm galvanized steel plate to the main steel structure and aluminum plate keel with nails and screws respectively to seal the fireproof rock wool.

[0042] Step 6: Installation of shaped aluminum plate.

[0043] Each aluminum plate is labeled after cutting, cutting, folding, installing corner pieces, reinforcing ribs and attaching frames in the assembly plant. During installation, it is installed in a fixed position with self-drilling and self-tapping nails according to the grid diagram, and the left and right positions of the plates are adjusted from top to bottom to ensure the flatness and joint spacing of the two adjacent plates. During construction and installation, the corner pieces fixed on the aluminum plate are directly hit on the keel with self-tapping nails, and the gaps between the plates are filled with foam strips and weather-resistant sealant. When installing the aluminum plate, the joints between the plates should be kept consistent to ensure the flatness of the curtain wall in the overall effect.

[0044] Step 7: Glue the aluminum plate.

[0045] 1) After the installation of the shaped aluminum plate, clean the plate seams and apply primer to prevent the sealant from being firmly connected to the aluminum plate. Then fill the foam strips. The depth of the foam strips should be consistent and no unevenness should occur.

[0046] 2) After the foam strips are filled, the masking tape is pasted. The masking tape should be pasted horizontally and vertically without distortion. During the gluing process, the glue injection should be continuous and full, and the glue scraping should be even and smooth without knife jumping.

[0047] The above embodiments describe the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
