What is a point supporting type to connect the glass curtain wall?

1, the spatial structure

The barge connection glass is a light steel load-bearing structure installed in an open space by a specially treated safety glass package. Usually the joint through the glass, the glass is fixed on a steel structure, which is characterized by the glass installation form does not like bright frame glass curtain wall as installed in the box and then connected with the main building, is not like that in the hidden frame glass curtain wall structure adhesive in aluminum frame.

2, supple surface

The barge glass system lies in its flexibility, a special device to make the glass in the wind under the action of free bending, the installation, the glass thickness is the same, it can be connected to more than fully rigid, installation of large area glass curtain wall.

3, reject the components of the system

The connection system consists of stainless steel joint and claw. The glass is connected with the connecting claw by the barge joint, and then connected with the light steel bearing structure through the claw. In addition to the joint action, the compensating claw also compensates for the size deviation caused by the glass processing and the structural manufacture. The connection system can be divided into single-layer glass barge and double glass barge system.

4, for single glazing system

(1) the front end of the V type barge joint system protrudes from the outer surface of the glass, and has better anti wind capability. (2) S type connection system of the joint and the front end of the outer surface of the glass is flush, the anti wind ability is worse than that of V negative type connection system.

5, for double layer (hollow) glass sealing system

(1) the joint of the D type barge connection system is connected with the inner and outer glass at the same time, and the front end of the joint is flush with the outer surface of the glass. (2) the joint of L type barge connection system is only connected with double deck glass. Due to safety reasons, laminated glass is usually used in Inner glass.

6. Connect the glass

Since the stress around the glass hole is considerable after installation, the glass used in the bonding system must be a specially treated tempered or tempered glass. The glass drilling form according to the selected connector in the form of straight into the hole and the cone two.

Generally speaking, as long as the structure deformation and the system can not coexist, all types of load-bearing structures can be used. They or glass plate reinforcement, metal mullion, space structure, contact structure, there are many possible bearing structure. The structural design takes into account glass and applied load limits to prevent deformation of the glass with a tendency to rupture. There are many factors that can deform the structure: strong wind pressure, glass weight, roof snow, thermal expansion, cleaning equipment, work load, and building shaking.

1. Glass plate reinforcement

In order to maximize the transparency of the glass surface, the glass can be mounted on the glass slab. These boards are often made of safe tempered glass. In addition to transparency, the introduction of different expansion between the glass and the supporting structure is another advantage because the expansion coefficient of the metal structure is higher than that of the glass. In general, the glass panels can be hung above the top of the structure or supported by the foundation. The shorter plate bars are suspended only at the top and terminate at approximately the height of the head, which also takes into account the possible use of space on the face of the cut glass. In this case, the ribs may be a little deeper. When the surface of the building is higher, the plate reinforcement can be connected by a metal plate and connected with a plurality of sections. However, it should check and make sure that the system remains safe when one of the panels is broken.

2. Glass hanging from each other

It is possible to hang the glass on the vertical line by using glass suspension connectors on other glass. This method of installation can overcome the risk of minor movement during earthquakes or deformation of structures subjected to side loads, but should check and ensure the safety of the system when a piece of glass is broken. Glass hanging clip and glass hanging clamp connector system when the glass over a length of 4 meters, glass installation should use glass hanging clamp connector installation. The glass is suspended on the upper steel structure by hanging clamp and connecting piece, and the back is divided into three kinds: single rib, double rib and through rib with glass rib. The single glass can reach up to 12 meters and the thickness is 15-19 millimeters. When the glass curtain wall more than 12 meters high, the glass hanging clamp connector is connected. Surface glass must be a specially treated tempered or tempered laminated glass.

1, deviation compensation

Although a very accurate traditional drilling machine is drilling on the glass, there is still a deviation at the hole and needs compensation. This deviation is compensated for by connecting the bolt in the glass curtain wall fittings system to the claw of the load-bearing structure. In the design, this part shall take into account the correction of the bolt position on the glass. The load bearing structure also suffers from deviation and needs compensation. The degree of deviation depends on the type of structure and the accuracy of the installation. The accurate positioning and adjustment of the claw in the structure (usually checked by theodolite) ensures the absolute smoothness of the surface.

2, tiny movement

Deviation compensation is not the sole function of the pawl, but it also compensates for excessive stresses occurring inside the glass when the structure is present. These deformations may be caused by wind pressure, snow, thermal expansion, and the installation of load-bearing structures. But the correct structure design should avoid excessive deformation, especially the parallelogram structure.

3. Design of intermediate parts

Normally, one of the two connecting bolts on each glass is the mounting point, and the hole on the pawl shall match the diameter of the connecting bolt. The second upper connecting bolts shall be able to move in the horizontal direction to compensate for deviations and minor movements. At this point, the hole on the catch is a long hole. Actually，
