Description

A point-supported glass curtain wall structure

technical field

The invention relates to an external maintenance structure of a building, namely a single-layer flexible chain rod supporting point-supported glass curtain wall structure, which is especially suitable for glass curtain walls with large openings on building facades, which have particularly high requirements for lighting and economy. system.

Background technique

In the past, the single-layer cable-net point-supported glass curtain wall structure or the steel truss structure supporting point-supported glass curtain wall structure was often used in the large opening of the building facade.

The single-layer cable network point-supported glass curtain wall structure has a very high architectural lighting effect, but because the cable material is expensive, the pre-tension of the cable has a large load on the main structure, resulting in an increase in the cost of the main structure and due to an extra layer in its construction. The construction cost is increased by applying a pre-tensioning process, so its economic performance is poor compared with other glass curtain wall structures.

The steel truss structure supporting point-supported glass curtain wall structure has a shorter construction period and better economy. However, due to the relatively large geometric dimensions of its supporting steel truss structure and the large number of rods, its lighting effect is poor.

Contents of the invention

The object of the present invention is to provide a new point-supported glass curtain wall structure, which adopts a single-layer flexible chain rod support structure, and has extremely high architectural lighting effects and good economic performance.

The object of the present invention is achieved in this way: it consists of a curtain wall support structure and a glass panel fixedly installed on the support structure, and is characterized in that the support structure adopts a single-layer flexible chain rod support structure, and the single-layer flexible chain rod support structure includes a horizontal The chain rod and the vertical chain rod, the horizontal chain rod and the vertical chain rod are respectively hinged between the pin shaft and the adapter, the glass panel is pressed on the adapter through the glass pressure plate, and the glass pressure plate and the adapter are passed through Screw connection, a rubber backing plate is installed between the glass pressure plate and the glass panel, and a sealant is used to seal the adjacent glass panels.

The horizontal link and the vertical link in the present invention adopt rigid rods.

The advantages of the present invention are:

1. A single-layer flexible chain rod support structure is adopted, and the horizontal chain rods and vertical chain rods, as well as the horizontal chain rods and vertical chain rods, are hinged through adapters. This structure can bear wind outside the plane. When loads such as earthquakes and earthquakes act, it has large deformation geometric nonlinear characteristics. After deformation outside the plane, the internal tension and external force generated inside form a balanced system; at the same time, the rubber backing plate can absorb the gap between the adjacent glass panels due to large deformation. Angular displacement between the glass to avoid warping stress.

2. Due to the small geometric size of the single-layer flexible chain rod support structure, the present invention has a very high architectural lighting effect.

3. Since the material cost of the main components of the single-layer flexible link support structure is low, and the structure does not require a large pre-tensioning force, the present invention has good economic performance.

4. The geometric dimensions of each component of the single-layer flexible chain rod support structure are small, and various high-end surface treatments such as high-temperature fluorocarbon spraying can be realized. The horizontal chain rods and vertical chain rods can be made into various geometric shapes, with rich artistic expressiveness.

Detailed ways

The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

As shown in Fig. 1, Fig. 2 and Fig. 3, the single-layer flexible chain rod support point-supported glass curtain wall structure of the present invention is composed of a support structure A and a glass panel 6 fixedly installed on the support structure A, and the support structure A includes The horizontal link 2 and the vertical link 1 are both connected to the adapter 3 , and the glass panel 6 is pressed onto the adapter 3 through the glass pressing plate 7 .

Referring to Fig. 4, Fig. 5 and Fig. 6, it can be seen that one side of the adapter 3 is a double hinge seat 13, and the upper and lower vertical chain rods 1 are inserted in the double hinge seat 13, and are respectively connected by pin shafts 4, A hinge is formed between the vertical link 1 and the adapter piece 3 . There are connecting plates 14 on both sides of the adapter 3 , and the end of the transverse link 2 is connected to the connecting plate 14 through a pin 5 , so that the transverse link 2 and the adapter 3 form a hinge.

As shown in Figure 4, Figure 5 and Figure 7, the glass panel 6 is press-fitted on the side of the adapter 3 through the glass pressure plate 7, the side of the adapter 3 has threaded holes, and the glass plate 7 and the adapter 3 Fixedly connected by hexagon socket head cap screws 11, rubber backing plate 8, rubber backing plate 9 and rubber backing plate 10 are installed between the glass pressure plate 7 and the glass panel 6, and the above structure forms a point support for the glass panel.
