[0021] See also Figure 1-Figure 2As shown, the present invention provides a laminated glass with a metal grille, comprising a frame 1, wherein a Low-E glass 2, a metal grille 3, a first glass 4, an SGP adhesive layer 5 and a second glass 6 are sequentially installed in the frame 1, and pressure plates 8 are arranged around the outer sides of the Low-E glass 2 and the second glass 6, and the pressure plates 8 are fixed to the frame 1, and the connection between the pressure plates 8 and the frame 1, the Low-E glass 2 and the second glass 6 is sealed by a sealant, and the pressure plates 8 are provided with a notch 81 for drainage, and the metal grille 3 comprises a rib 7 and a plurality of metal rods, and the rib 7 is provided with a plurality of slots at intervals along the length direction thereof, and the plurality of metal rods are correspondingly inserted into the plurality of slots, and both ends of the rib 7 and the two ends of the metal rod are connected to the frame 1. The laminated glass is used for the skylight, and the Low-E glass 2 is arranged outward. The surface emissivity E of the Low-E glass is low, and the absorption of external energy and the re-radiation of heat energy are small; the far-infrared heat radiation is directly reflected and the reflectivity is high; the shading coefficient Sc has a wide range (0.2-0.7), and the direct solar radiation entering the room can be adjusted as needed. The LOW-E film layer is plated with a silver layer, and the silver can reflect more than 98% of the far-infrared heat radiation, thereby directly reflecting the heat like a mirror reflecting light. In summer, the outdoor temperature is higher than the indoor temperature, and the far-infrared heat radiation from the outdoor can be reflected by the LOW-E glass with a low shading coefficient to prevent the heat from entering the room. In winter, the indoor temperature is higher than the outdoor temperature, and the far-infrared heat radiation from the indoor temperature can be reflected back to the indoor temperature by the LOW-E glass to keep the indoor heat from leaking out. Part of the solar radiation from the outdoor enters the room through the LOW-E glass, and part of the energy is absorbed by the indoor objects and then converted into far-infrared heat radiation and retained in the room. Therefore, low-e glass can be called an energy-saving material, which can reduce the air conditioning costs in winter and summer. The addition of metal grilles can provide better shading and decorative effects, making it more beautiful and hiding dust. In addition, the addition of metal grilles can greatly enhance the safety performance of the device, making the skylight safer and less prone to damage.

[0022] As an implementation method, the thickness of the Low-E glass 2 is 15mm, the thickness of the first glass 4 and the second glass 6 is 12mm, the diameter of the metal rod is 50mm, and the spacing between two adjacent metal rods is 50mm. The cross section of the Low-E glass 2 is rectangular and has a size of 2m×4.5m. The metal rod is made of aluminum alloy, and the pressure plate 8 is an aluminum alloy plate, which is prepared by fluorocarbon spraying. The Low-E glass 2 is high-transmittance double silver Low-E, and the first glass 4 and the second glass 6 are ordinary tempered glass. The laminated glass can be written as TP15 (high-transmittance double silver Low-E) + 22A (aluminum alloy grid 50x12@50mm) + TP12 + 2.28SGP + TP12, 22A (aluminum alloy grid 50x12@50mm) height 22mm, 5cm outer diameter 1.2cm thickness, spacing 50mm, TP12, that is, tempered glass thickness 12mm.

[0023] See also Figure 3-Figure 7 As shown, a method for installing laminated glass with a metal grille, wherein the laminated glass is used for a skylight of a building, the bottom of the building is normally constructed, and the top is constructed with a main steel beam, the main steel beams are staggered and connected to form a plurality of openings of a size matching the laminated glass, the laminated glass is installed at the opening, and the installation of the laminated glass includes the following steps: S1. Use steel pipes to splice and weld to form a steel keel, transport the steel keel to the top of the building, and weld it to the main steel beam. The shape of the steel keel corresponds to the shape of the laminated glass, and a plurality of steel plate connectors are welded on the top surface of the steel keel; S2. Fill the steel keel with thermal insulation rock wool and TPO waterproof layer, and weld aluminum plates on the outside for sealing; S3, transporting the laminated glass to the roof, placing it on the steel keel, connecting it to the steel plate connector through stainless steel bolts, and injecting glue after fixing it to ensure the sealing of the connection between the laminated glass and the steel keel; S4, installing each of the laminated glasses in sequence until the laminated glasses are installed at all the openings; S5. Install stainless steel plates between adjacent laminated glasses, and connect multiple stainless steel plates to form drainage ditches.

[0024] Preferably, the steel pipe in step S1 is a galvanized steel pipe with a diameter of 76 mm, and the spacing between adjacent steel plate connectors is 518 mm. In step S2, the thickness of the aluminum plate is 2.5 mm, the thickness of the thermal insulation rock wool is 75 mm, and the thickness of the TPO waterproof layer is 1.5 mm. In step S5, the connection of the stainless steel plate is a high point pressing low point (the top of the building is convex, and water flows from high to low), and a 5 mm thick weather-resistant sealant is applied between the stainless steel plates, the high point is plugged in and the low point is pressed, and the overlap length is ≥ 20 mm. Example

[0025] The area of ​​a single glass piece is 9 m2, the maximum weight of a single glass piece is 800 kg, the number of glass pieces is 256, the total area of ​​the skylight is 1,800 m2, the roof has a vertical and horizontal gutter system, and a tower crane is used for vertical transportation and installation of glass.

[0026] The reference axis and elevation provided by the general contractor are checked. After confirmation, the installation reference line is determined. Position steel wires are set according to the reference line, which is used as the frame reference. To ensure that it is not affected by other factors, the upper and lower steel wires maintain fixed fulcrums, and the entry and exit position lines are based on the axis of the outer wall as the reference line, so as to ensure that the frame installation meets the design and specification requirements.

[0027] The construction of the skylight roof uses a spider car to install the aluminum alloy decorative lines at the bottom. The cutting and assembly of the steel keel is completed on the roof. After the steel keel welding is completed and inspected, the tower crane is used to hoist them into place piece by piece. After the decorative lines and decorative aluminum panels at the bottom of the skylight roof are installed, the glass is installed.

[0028] The connector is made of 8mm galvanized steel parts, which are welded to the top surface of the steel keel with a height of 7mm. The height of the connector is a variable to adjust the height of the steel keel of the skylight. The left and right directions of the φ76 steel round tube are positioned by spot welding between the connector and the steel structure. The distance between two adjacent connectors is 518mm. The center line of the φ76 steel round tube is also the center line of the connector, so pay attention to controlling the position of the connector during installation, and its deviation should be less than 2mm. Pull the horizontal line to control the horizontal height and the in-and-out dimensions. Although the horizontal height has been controlled during the construction of the steel structure, due to the influence of construction errors, the horizontal line should still be pulled when installing the connector to control the horizontal and depth positions to ensure that the connector is installed accurately.

[0029] 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 entry and exit position of the adapter should be checked and verified again to ensure the accuracy of the position and elevation. In order to facilitate construction and improve installation efficiency, each glass-separated steel frame should be cut and welded on the roof. After the keel shape is welded, it should be welded and fixed to the connector. The construction quality of each weld should be checked one by one (the weld grade is grade three). The main inspection is the three-dimensional spatial error. The deviation must be controlled within the error range allowed by the specification. The three-dimensional spatial error construction control range is less than 2mm for vertical error and less than 2mm for horizontal error.

[0030] After the frame is installed, it should be checked, mainly the following contents: whether the various beams are in place, whether the interfaces between beams are consistent, whether the beams are level and meet the design requirements, whether there is any torsion, whether the upper and lower sides of the beams are in the same plane, etc. The beam flatness error is ±2mm, the horizontal error is less than 3mm within 20m, and the error is less than 5mm outside 20m. The diagonal length difference error of the steel beam grid is ±3mm. The spacing of the steel beam grid is 570mm, and the theodolite is used to check whether each steel grid in the plane meets the design requirements; the straightness is within the range of ≤2.5mm; the elevation of the adjacent steel frame is within the range of <3mm; use a steel ruler, nylon line or laser gold station to check. To prevent welding deformation, after the keel installation and positioning is completed, full welding is carried out from the middle to the periphery, and the adapter is welded to the reserved points of the steel structure. The height of the fillet welds of the weld grade three meets the requirements, the welds are dense and the welding is firm, the welding slag has been cleaned and the appearance is full, the weld surface is fully coated with anti-rust paint twice, and anti-rust treatment is carried out. The surface of the paint layer is full and has no dew points, which meets the requirements of design and construction specifications. For all the grade three welds on site, the height of the fillet welds meets the requirements, the welds are dense and the welding is firm, the welding slag has been cleaned and the appearance is full, the weld surface is fully coated with anti-rust paint, and anti-rust treatment is carried out. The surface of the paint layer is full and has no dew points, which meets the requirements of design and construction specifications.

[0031] Before installing the glass, prepare the manual hoist, suction cup, wrench and other tools required for construction, and check to ensure that they are easy to use and have no hidden dangers. On-site technicians should do a good job of technical briefing according to the design and construction requirements, so that each installation team member is familiar with the installation process and installation essentials. Do a good job in safety education, and do a good job in safety precautions and material protection during the installation process. Use a tower crane with a mechanical suction cup to lift the glass plate to the construction platform. By improving the sealing performance to ensure the sealing performance between the suction cup and the surface of the object, gas leakage can be effectively reduced and the adsorption force can be improved. This can be achieved by replacing the sealing pad or increasing the number of sealing pads. Adjust the ambient temperature and humidity The ambient temperature and humidity have a certain effect on the adsorption force of the vacuum suction cup, which can be improved by adjusting the ambient temperature and humidity. Suction cup cleaning Dust and dirt on the surface of the suction cup will affect the adsorption force, and regular cleaning of the suction cup surface can effectively improve the adsorption force. Adjust the ambient temperature and humidity The ambient temperature and humidity have a certain effect on the adsorption force of the vacuum suction cup, which can be improved by adjusting the ambient temperature and humidity. Suction cup cleaning Dust and dirt on the surface of the suction cup will affect the adsorption force, and regular cleaning of the suction cup surface can effectively improve the adsorption force.

Suction cup cleaning Dust and dirt on the surface of the suction cup will affect the adsorption force, and regular cleaning of the suction cup surface can effectively improve the adsorption force.

[0032] The maximum weight of a single piece of glass for the skylight roof in this project is about 800kg. The tower crane can cover the entire operating area of ​​the skylight roof. The length of the 2# crane arm is 50m, and the length of the 5# crane arm is 44m. The lifting mass is 9.85t, which can meet the lifting and installation of the skylight roof glass. The skylight roof glass is fixed with stainless steel bolts and steel keels, and the glue is injected after the glass panels are installed. The gaps between the panels must be fully cleaned when injecting glue to the skylight roof glass. There should be no water, oil stains, dust and other debris. The bonding surface should be fully cleaned and dried. The foam strips should be filled continuously, and the glue should be connected tightly. When encountering the tongue, it should be close to both ends of the tongue, and masking tape should be pasted on the tongue. The tape should be firmly and densely pasted, and the corners and joints should be connected smoothly and close to the edge of the board. When pasting the tape, it is not allowed to open, fall off, or be not straight. In the gluing project, the seam glue should be smooth and full, the joints should not have defects such as bumps and lines, and the connection with the stone should be tight, and there should be no cracks or sand holes. After gluing, the tape should be cleaned up in time when the glue is almost dry, and the glue surface that was damaged when the tape was removed should be handled immediately. The thickness of the glue should not be too thin or too thick, and the surface of the glue should be flat and smooth, the glass should be clean and free of dirt, the top, edge and bottom seals should be firm and beautiful, and watertight, and the water on the top should be drained inward. After gluing, the glue that contaminates the board surface should be cleaned up in time.
