After the glass is inserted into the slot, use sealant (e.g. silicone sealant) fill the gap between the glass and the tank wall to fix
Definition: When the height of curtain wall is low, the surface glass and rib glass are installed with inlaying groove, and the glass is fixed in the bottom inlaying groove, and a certain space is set aside between the top of the upper inlaying groove and the glass, so that the glass has room for expansion and deformation. Advantages: Simple structure, low price, mainly relies on pedestal for weight bearing Weakness: The glass is easy to bending and deformation under its own mass load, resulting in visual image distortion.Pay-off → Installation of upper bearing steel structure → Lower and side frame mounting → Glass installation → Inject glue and seal → Clean and inspection 1.Positioning 1. The measuring and laying out of curtain wall positioning axis must be parallel or vertical with the main structure axis, so as to avoid the contradiction between the curtain wall construction and indoor and outdoor decoration construction, resulting in the defects of the Yin and Yang Angle is not square and the decoration surface is not parallel. 2. Use high precision laser level, theodolite, match to standard steel tape, hammer, level ruler to recheck. For the curtain wall with a height greater than 7m, it should be measured and checked twice to ensure the vertical accuracy of the curtain wall. The deviation between the upper and lower center lines must be less than 1 mm to 2mm. 3. The measured lay-off shall be carried out when the wind force is not greater than force 4, the error between actual wiring and design drawing should be adjusted, distributed and digested, it can not accumulate. It is usually solved by adjusting the width of the gap and positioning of the frame. If the size error is large, reflect in time, and remake glass or use other reasonable solution. 5. The all-glass curtain wall is directly fixes the glass to the main structure, first bounce glass to the ground, and then determine the anchorage point according to the outer edge size.
Note: the sealing performance of wet type assembly is better than that of dry type assembly, and the service life of silicone sealant is longer than that of rubber sealing strip.| No ribbed glass full glass curtain wall | |
| Node structure | Glass fixed installation method |
| The common used way is insert the ends of a large piece of glass into metal frame and fix it with silicone structural sealant | There are three kinds of glass fixed installation method, Dry type assembly, Wet-type assembly, Mixing assembly. |
When installing glass, use sealing strips (such as rubber sealing strips) to fix
There are two types for full glass facade structure, one is with ribbed glass structure, the other is without ribbed glass. Ribbed glass: In order to strengthen the stiffness of glass panels, it is necessary to use strip glass as reinforcement ribs at a certain distance, known as ribbed glass
| Ribbed glass full glass curtain wall | |
| Intersecting surface structure of ribbed glass | |
| The direction of the rib glass surface is arranged mainly according to the location and function of building, and the artistic requirements. There are usually three structural forms regarding intersection treatment of face glass and ribbed glass: Double ribbed, Single ribbed, Through ribbed. |
Ribbed glass on one side, suitable for external wall
Ribbed glass through the surface glass, suitable for large surface curtain wall.
1. Tempered glass; 2. Tempered glass rib; 3. Stainless steel hanging clamp system; 4. Indoor ceiling line; 5. Structural glass glue
The glass rib is located at the rear of the face glass, bonded to the face glass with structural adhesive as a whole.
The glass rib is located between two face glass, one side of the ribs is flush with surface of face glass, and the structural adhesive is used between the ribs and two face glass. There would be chromatic aberration in vision due to the different lateral transmittance thickness
The glass rib is located at the joint of two face glass, and three pieces of glass are connected together with structural glue
The glass rib is located between the two face glass, both sides protrude surface of face glass, the ribs and the face glass are sealed with structural adhesive.
Definition: When the curtain wall is high, in order to prevent the glass from buckling and destruction under its own mass load, special metal fixture is set at the upper end of the curtain wall, and the large piece of glass is hung up to form continuous glass curtain wall without deformation. There is a flexible space between the glass and the bottom of the inlaying groove. Advantages: It can eliminate the glass deflection caused by its own quality and create a beautiful, transparent and safe effect. It mainly relies on metal fixtures for weight bearing. Weakness: The structure is relatively complex and cost highly1.19 mm glass; 2.Exterior finish; 3.Silicone sealant; 4.Interior surface; 5.3mm SS channel steel profile; 6.Foam filling material; 7.Neoprene spacer; 8.Embedded parts; 
1.The gap between the surrounding closed groove wall and the glass panel or the glass rib should not be less than 8mm, the gap between the lower end of the hanging glass and the bottom of the lower groove should meet the requirements of glass elongation deformation. The glass and the bottom of the lower groove should be supported or filled with an elastic pad and the length of the pad should not be less than 100mm, the thickness not less than 10mm, It shall be sealed with silicone building sealant between the cell wall and the glass. 2.The surface of the full glass curtain wall shall not be in direct contact with other rigid materials. The gap between the plate surface and the decoration surface or the structural surface should not be less than 8mm, and sealed with sealant.Diagram of upper node of hanging type full glass curtain wall1.Bolt installation; 2. teel hanging bracket; 3.Steel beam; 4.External metal clip; 5.Internal metal clip; 6.Slings; 7.Suspension clamp plate; 8.3mm SS channel steel profile; 9.Exterior finish; 10.Silicone sealant; 11.19 mm glass; 12.Internal ceiling;| Intersecting surface treatment of ribbed glass | |

3.Internal and external metal clasps
The inner and outer metal clamps are the edge sealing structures on the upper part of the glass curtain wall after the glass suspended, it’s better to choose stainless steel.
2.Upper steel structure installation 1. Pay attention to check the embedded part or anchoring steel plate is firm, the quality of anchor bolt should be reliable, the location of the anchor bolt should not be close to the edge of the reinforced concrete member, the diameter and depth of borehole should meet technical stipulation of anchor bolt manufacturer, the hole ash should be cleaned up. 2. The installation position and height of each component shall strictly proceed in accordance with the requirements of wiring positioning and design drawings. The most important is that the center line of the load-bearing steel beam must be consistent with the center line of the curtain wall, and the center of the elliptical screw hole should be consistent with the position of the designed derrick bolt. 3. Internal metal clip installation must be smooth and straight. It is necessary to use subsection pull-through line to check and straighten the deflection caused by welding. The outer metal buckle clamp should be assembled according to the serial number, and require straightness. The spacing of internal and external metal clips should be uniform and the size should meet the design requirements.size.3.Underframe and side frame mounting Construction in accordance with the wiring positioning and design elevation, all steel structure surface and weld joint brush anti-rust paint. Clean up the dirt inside the lower border. At least 2 neoprene pads should be placed at the bottom of each piece of glass, and the length should not be less than 100mm.4.Glass installation Glass lifting and placement shall be carried out in strict accordance with the site construction process5.Silicone Sealant Injection and Cleaning The construction thickness of weather resistant silicone sealant should be between 3.5 ~ 4.5mm, too thin sealant joints is unfavourable for the quality of sealing and prevent rain. In addition, the glue injection should not be carried out at a low temperature of less than 5℃, because the temperature is too low, the glue will flow, delay the curing time, and even affect the tensile strength. Stick adhesive tape along the joint position to prevent silica gel from contaminating the glass. Professional rubber injection construction. After the glue injection, use special tools to scrape the glue, makes the glue seam is slightly concave surface. The glass and metal surface of the glue injection part should be wiped clean with acetone or special detergent, do not use wet cloth and water.There are two types for full glass facade structure, one is with ribbed glass structure, the other is without ribbed glass. Ribbed glass: In order to strengthen the stiffness of glass panels, it is necessary to use strip glass as reinforcement ribs at a certain distance, known as ribbed glass
The structure of hanging glass curtain wall is mainly composed of three parts: 1.Upper load-bearing hanging structure: steel hanger, steel beams, suspension hanger, horseshoe hanging fixture, hanging clamp copper, internal and external metal clip, filling and sealing material, weather resistant silicone sealant. 2.Middle glass structure: glass panel; Glass ribbed plate, silicone structural sealant. 3.Lower frame structure: metal frame, neoprene rubber pad, foam filling material, weather-resistant sealant.FunctionThe glass is positioned in the upper part, so that the face glass can be evenly transmitted to the rib glass and steel hanger after bearing the wind load. At the same time, it is also the junction and closing position of the indoor suspended ceiling and outdoor decorative materials and the full glass curtain wall.InstallationIn order to hoist the face glass in place, fix the inner metal clip first, and then fix the outer metal clip with the installation bolt after the glass is suspended.
1.Type: tempered glass, laminated tempered glass etc. 2.Thickness: through design and calculation to determine, the more commonly used is 12/19mm. 3.Edge treatment: should be polished and prevent small gaps after cutting glass, the gap is easy to form stress concentration result in the glass cracking.
In the hanging type full glass curtain wall project, the metal frame buried below the ground or in the wall is better to use 3mm thick stainless steel groove steel metal frame.
1.Strength calculation: Silicone structural adhesive is used between the face glass and the ribbed glass, the width and thickness of the adhesive joint should be checked by strength. 2.Sealant: Neutral silicone sealant should be used between glass and metal frame and buckle.
