Glass is widely used in modern development and has been a product with a large market demand. Through the use of specific treatment methods, we can not only give full play to the characteristics of the glass, but also make up for its defects, no longer subject to the natural properties of the glass. For example, laminated glass can not only insulate heat, but also prevent debris from splashing and hurting people. It is safe and reliable. Next, we will introduce the monolithic size of the glass curtain wall and the monolithic size of the glass curtain wall.
1. Size and specifications of point glass curtain wall
The center main facade point-type glass wall is about 1200 m 2, except for the bottom row of the curtain wall, 1 2 1 2 A 8 tempered hollow glass , I use {{5}} 1 2 A {{5}} tempered insulating glass. The design is based on the basic wind pressure standard value of 0. 40 kN / m { {1}}, steel structure limit temperature difference value 41 ℃, glass limit temperature difference value 8 0 ℃, seismic fortification six degrees, fire resistance level considered. The steel structure coating selects base sandblasting Sa { {1}}. 5 grade, Sz-1G inorganic galvanized coating for anti-corrosion coating, thickness {{5}} 0μm, anti-corrosion period 2 0 years; steel pipe, galvanized steel The grooves and steel rods are made of Q 2 3 5; the materials of stainless steel rods, steel claws (type X) and fasteners should comply with GB1 2 2 0; weather resistance Dow Corning DC 793, DC99 5 is adopted for the sealant and structural silicone adhesive; the quality of other materials must meet the relevant specifications and standards.
　　1. If it is a floor-standing glass curtain wall, the technical specifications of the glass curtain wall engineering stipulate that the glass thickness should not be less than 10 mm and must be tempered glass (a certain corner of the glass must have {{2 }} C certification!), 10 mm tempered glass shall not be greater than 3 m, {{{5}}} mm tempered glass shall not be greater than 4 m, {{7 }} mm tempered glass should not be greater than 5 m, because the glass has its own weight. When the thickness is inversely proportional to the height, the self-weight will cause the glass to bend and deform, which is easy to cause self-explosion and affect the safety of use;
　　2. The glass curtain wall installation has the following requirements for the thickness of the glass. If it is insulating glass, the general specifications of insulating glass are: 12A 6, 812 A {{6}}, etc., because the technical specifications of the glass curtain wall engineering stipulate that the thickness of the glass of the glass curtain wall should not be less than {{2 }} mm, if hollow glass is used, the thickness of the hollow layer shall not be less than 9 mm, then the size specification of hollow glass is: 6 mm 9 A 6 mm;
　　3. When installing glass, you need to pay attention to avoid scratches and collisions. When installing large pieces of glass, you must use manual suction cups to ensure that the injury of the glass sheet is reduced during the construction process, because the tempered glass after collision Will break the whole piece;
　　4. For example, what kind of curtain wall (full hidden / semi-hidden / full bright / hanging / dot / unit) each type of curtain wall needs different attention during construction
2. Requirements for curtain wall glass
　　1. The glass curtain wall shall adopt curtain wall glass with a reflectance not greater than 0. 30. For the glass curtain wall with lighting function requirements, the lighting reduction factor should not be lower than 0. 20.
　　2 The tempered glass shall be used for the panel glass of the point supporting glass curtain wall.
　　3. Frame supported glass curtain wall, safety glass should be adopted.
　　4. Point-supported glass curtain walls supported by glass ribs shall be tempered glass.
　　5, people with high density of movement, public places for teenagers or young children ’s activities, and places prone to impact during use, the glass curtain wall should use safety glass; for the parts prone to impact during use, it should be set obvious Warning sign.
