[0035] Please refer to Figures 1-2As shown, the present application provides a metal grille laminated glass, comprising a frame 1, a Low-E glass 2, a metal grille 3, a first glass 4, an SGP glue layer 5 and a second glass 6 are sequentially arranged in the frame 1, the Low-E glass 2 and the second glass 6 are provided with a pressing plate 8 around the outer side, the pressing plate 8 is fixed on the frame 1, the connection between the pressing plate 8 and the frame 1, the Low-E glass 2 and the second glass 6 is sealed by sealing glue, the pressing plate 8 is provided with a notch 81 for drainage, the metal grille 3 comprises a rib 7 and a plurality of metal rods, a plurality of slots are arranged in the length direction of the rib 7, a plurality of metal rods are correspondingly inserted into the plurality of slots, and both ends of the rib 7 and the metal rods are connected to the frame 1. The laminated glass is used for a daylighting roof, and the Low-E glass 2 is arranged outward, the surface emissivity E of the Low-E glass is low, the absorption of external energy and the re-radiation of heat energy are small, the far infrared thermal radiation is directly reflected, and the reflectivity is high; the shading coefficient Sc is wide (0.2-0.7), and the direct solar radiation entering the room can be adjusted according to needs.

The installation of the laminated glass comprises the following steps:

[0038] S1, the steel pipes are spliced with each other to form a steel keel. The steel keel is transported to the top of the building and welded to the main body steel beams. The shape of the steel keel corresponds to the shape of the laminated glass. A plurality of steel plate connectors are welded on the top surface of the steel keel;

[0039] S2, the inside of the steel keel is filled with thermal insulation rock wool and a TPO waterproof layer, and the outside is sealed by welding an aluminum plate;

[0040] S3, the laminated glass is transported to the roof and placed on the steel keel. The laminated glass is connected to the steel plate connector by stainless steel bolts.

[0045] According to the reference axis and elevation line provided by the general contractor, the installation reference line is determined after checking and confirming that there is no error. The position steel wire is drawn according to the reference line, which serves as the vertical frame reference. To ensure that it is not affected by other factors, the upper and lower steel wires maintain fixed fulcrums, and the position line is hung from the exterior wall axis as the reference, thereby ensuring that the skeleton installation meets the design and specification requirements.

[0046] The spider car is used to install the aluminum alloy decorative line at the bottom of the daylighting roof, the cutting and assembly of the steel keel are completed on the roof, and the tower crane is used for hoisting and positioning after the steel keel welding is completed and inspected. After the installation of the decorative line and decorative aluminum plate at the bottom of the daylighting roof is completed, the glass is installed.

[0047] The connecting piece is a 8 mm galvanized steel workpiece, which is positioned and welded to the top surface of the steel keel with a welding angle height of 7 mm. The connecting piece height is a variable adjustment for the high and low positions of the daylighting steel keel. The φ76 steel round pipe is positioned in the left and right directions by the connecting piece and steel structure spot welding. The distance between the two adjacent connecting pieces is 518 mm. The center line of the φ76 steel round pipe is also the center line of the connecting piece, so the position of the connecting piece needs to be controlled during installation, and the deviation should be less than 2 mm. Although the horizontal height has been controlled during the construction of the steel structure, due to the influence of construction errors, the horizontal and depth positions still need to be controlled by pulling the horizontal line during the installation of the connecting piece to ensure the accurate installation of the connecting piece.

[0048] Before installing the steel connector, the surface of the steel structure should be cleaned. When welding the double-span connector, the center line and the in-out position of the connector should be checked again to ensure the accuracy of the position and elevation. In order to facilitate construction and improve installation efficiency, the steel frame of each glass partition should be cut and welded on the roof. After the keel modeling is welded, it is welded to the connector. Each weld is checked for construction quality (welding grade is three). The main inspection is the three-dimensional space error. The deviation must be controlled within the allowable error range of the specification. The three-dimensional space error of the site construction control range is that the vertical error is less than 2mm and the horizontal error is less than 2mm.

[0049] After the frame is installed, it should be checked. The main checks are as follows: whether the positioning of various beams is correct, whether the beam and beam interface fits, whether the beam is horizontal, whether the beam meets the design requirements, whether there is torsion, whether the beam upper surface is in the same plane, etc. The beam flatness error is ±2mm, the horizontal error is less than 3mm within 20m, the error is less than 5mm outside 20m, and the steel beam grid diagonal line length difference error is ±3mm. The steel beam grid spacing is 570mm. The theodolite checks whether each steel grid in the plane meets the design requirements; the straightness is within the range of ≤2.5mm; the elevation of adjacent steel frames is within the range of <3mm; and the steel ruler, nylon line or laser station instrument is used for inspection. In order to prevent welding deformation, after the keel installation positioning is completed from the middle to the periphery, full welding is carried out, and the connector and the steel structure reserved point position are welded. The welding grade is three. The height of the fillet weld meets the requirements. The weld is dense and firm. The welding slag has been cleaned up. The appearance is full. The weld surface is fully coated with anti-rust paint twice. The rust is treated. The paint layer surface is full and has no dew point, which meets the design and construction specification requirements. All three-level welds on site meet the requirements.

[0050] Glass installation before the preparation of the construction required hand hoist, suction cup, wrench and other tools, and check to make sure good use of no hidden trouble. On-site technical personnel according to the design construction requirements to do well technical disclosure work, so that every installation team member is familiar with the installation process and installation essentials. Do a good job in safety education work, in the installation process to do a good job in safety prevention and material protection work. Use tower crane with mechanical suction cup to hoist glass plate to the construction platform. By improving the sealing performance to ensure the sealing performance of the suction cup and the surface of the object can effectively reduce the gas leakage, improve the adsorption force. Can be achieved by replacing the sealing gasket or increasing the number of sealing gasket. Adjust the environmental temperature and humidity Environmental temperature and humidity have a certain influence on the adsorption force of the vacuum suction cup, which can be adjusted by adjusting the environmental temperature and humidity to improve the adsorption force. Dust and dirt on the surface of the suction cup will affect the adsorption force, regular cleaning of the surface of the suction cup can effectively improve the adsorption force.
