Embodiment 1

[0039] Such as Figure 1 to Figure 5 As shown, the prestressed cable-point curtain wall structure includes a cable, a strut 3, a connection device 5 and a curtain wall glass 6, and the two ends of the cable are fixed on the truss 1 of the building or on the ground anchor 7. The draglines include two main draglines 2, the number of the struts 3 and the connecting devices 5 are multiple, and the numbers of the struts 3 and the connecting devices 5 are equal;

[0040] The struts 3 are provided with two cable fixing parts, the struts 3 are arranged side by side in a row, and the two main cables 2 pass through the different cable fixing parts on each strut 3 successively, and are located at two The struts 3 between the main cables 2 constrain the main cables 2 into a corrugated or arc shape, and the two main cables 2 cross each other, and the two main cables 2 are both in a tensioned state;

[0041] Each support rod 3 is fixed with a connecting device 5 , and the connecting device...

Embodiment 2

[0046] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 5 As shown, as a specific connection form of the main stay cables 2 on the building, the upper ends of the two main stay cables 2 are fixed on the truss 1 of the building, and the lower ends of the two main stay cables 2 are fixed on the ground anchor 7 Above, the projections of the two main cables 2 toward the side of the curtain wall glass 6 are both straight lines, and the two straight lines coincide, and the struts 3 are perpendicular to the plane where the curtain wall glass 6 is located. The above connection form of the main cable 2 on the building, the gravity of the curtain wall glass 6 support structure composed of the main cable 2, the strut 3 and the connecting device 5 can be balanced by the pulling force on the main cable 2, which can effectively avoid or Reduce the impact of the gravity of the supporting structure of the curtain wall glass 6 on the stress of the ...

Embodiment 3

[0054] This embodiment further defines the present invention on the basis of any one of the technical solutions provided in embodiment 1 or embodiment 2:

[0055] Such as Figure 1 to Figure 5 As shown, in order to facilitate the realization of connecting a large glass curtain wall into a whole, to realize the mutual restraint of the glass support structure of the glass curtain wall, which is beneficial to the stability of the whole, two main cables 2, multiple support rods 3, A plurality of connecting devices 5 form a glass fixing part, and the glass fixing part is multiple, and also includes a plurality of integral cables, and each integral cable has a connection point with the glass fixing part.

[0056] At the same time, this embodiment provides a specific application example. The curtain wall structure is used as the curtain wall of the commodity exhibition center. The total construction area of ​​the commodity exhibition center is 116702.46 square meters, and the main bo...

Abstract

The invention discloses a prestressed cable point-supporting curtain wall structure and a construction method. The curtain wall structure comprises cables, multiple support rods, multiple connection devices and curtain wall glass, wherein the cables comprise two main cables; the number of the support rods is equal to that of the connection device; two cable fixing parts are arranged on each support rod, the support rods are arranged in parallel in a row, and the two main cables sequentially penetrate through different cable fixing parts on each support rod, are restricted to be corrugated or arched, and are intersected; one connection device is fixedly arranged on each support rod, and the curtain wall glass is fixedly arranged on the connection devices. The curtain wall structure is low in space occupation rate and small in overall weight, and has certain flexibility, and the curtain wall glass can be stably supported. According to the construction method, the internal stress of each point on the main cables can be consistent or has smaller differences.

Description

technical field [0001] The invention relates to the technical field of curtain wall buildings, in particular to a prestressed cable-point curtain wall structure and a construction method. Background technique [0002] Glass curtain wall is a kind of beautiful and novel building wall decoration method, and it is a remarkable feature in the era of modernism high-rise buildings. The earliest curtain wall surface layer was made of steel materials. Nowadays, aluminum alloy keel and glass surface layer are mostly used. The glass curtain wall has a good visual effect, and the light transmission of the glass is very good. The intensity of indoor artificial lighting during the day can be greatly reduced. [0003] In the structural design of the glass curtain wall, the glass curtain wall is very different from the ordinary wall: because the glass curtain wall generally spans floors to make the appearance of the entire building a whole, so the curtain wall design should consider such f...
