Background

The stay cable curtain wall system generally adopts vertical cables or cable nets (both transverse cables and vertical cables) as a supporting structure, and the corners of the glass are clamped by connectors at the cross seams between the glass plates. The stay cable curtain wall has the characteristics that the outer vertical surface is simple and clean, the stay cable components are small and do not obstruct the sight, and the like, and can create a simple, clean and transparent visual effect. However, the stay cable curtain wall is large in span and large in whole wind load area, so that the end of the stay cable transmits large reaction force to the fixed supporting structure, and a large civil structure beam is taken as a supporting structure during design. The larger structural beam is inevitably huge in size, and the larger position and space need to be considered for arrangement during structural design, so that the indoor space planning and the outdoor building effect are influenced to a certain extent.

In practice, in the design of many guy curtain wall boundary structures, the boundary structure for fixing the guy adopts a smaller steel structure or a civil structure beam, namely, under a soft boundary, because the guy curtain wall has a larger span, a larger deformation amount is formed to the guy curtain wall, and a fluctuating acting force is generated under the action of irregular wind load on the guy curtain wall, so that great influence is caused on the deformation and the use safety of the structure.

Detailed Description

As shown in fig. 1 to 4, an elastic adjustment structure of a cable curtain wall comprises a fixed steel plate 1, a lower movable support plate 2, an elastic member 3 and a guide member 4, wherein the fixed steel plate 1 is fixedly connected to a main steel structure 5, the main steel structure 5 comprises two transverse i-shaped steels 51, a plurality of small i-shaped steels 52 are uniformly connected between the two transverse i-shaped steels at intervals, the fixed steel plate is welded above the two corresponding small i-shaped steels, a lower movable support plate 2 is arranged below the fixed steel plate 1, the elastic member 3 is clamped between the fixed steel plate 1 and the lower movable support plate 2, the elastic member 3 is preferably a spring, the fixed steel plate 1 is connected with the lower movable support plate 2 through at least three guide members 4, the upper end of each guide member 4 is fixedly connected to an upper fixed steel plate 7, the lower movable support plate 2 can reciprocate along the guide members 4, the spring is limited in a space surrounded by the guide members 3, when the pull cable is stressed, the spring moves transversely, the guide piece has the functions of a guide rail and limiting, the cable head 61 of the curtain wall pull cable 6 is fixedly connected to the lower movable support plate 2 and inserted into the through hole of the spring, and the steel twisted rope 62 of the pull cable 6 extends out along the through hole formed in the fixed steel plate 1. The lower movable support plate, guide and spring are located in the main structural space enclosed by the two transverse i-beams 51 and the two small i-beams 52.

Specifically, the guide 4 comprises a screw rod 41 and a nut 42 assembly, the upper end and the lower end of the screw rod 41 respectively penetrate through the fixed steel plate 1 and the lower movable support plate 2 correspondingly and are in threaded connection through the nut 42, and the nut at the upper end of the screw rod is fixedly connected with the fixed steel plate. The lower end of the screw rod can be a nut or an end head integrally formed with the screw rod.

In order to be stressed more uniformly, the screw nut assemblies are four sets and are arranged around the spring at uniform intervals.

The roof of fixed steel sheet links firmly last fixed support board 7, is equipped with the through-hole that supplies the steel strand rope of screw rod and cable to pass respectively on this last fixed support board 7. The nut at the upper end of the screw nut component is fixedly connected with the top wall of the upper fixed supporting plate. The effective supporting length of the screw rod can be increased by increasing the upper fixing supporting plate, force can be dispersedly transmitted to the fixing steel plate on the other hand, and the force of the spring and the force of the screw rod hole are prevented from acting on the middle position of the fixing steel plate.

Preferably, the upper fixed support plate 7 and the lower movable support plate 2 are both circular plate bodies.

When the cable head of the stay cable is pulled by the steel strand of the stay cable, the lower movable support plate is driven to compress the spring along the screw rod and the matched washer and nut of the cable lock head, and the load is transferred from the path of the steel strand of the stay cable → the cable head of the stay cable → the lower movable support plate → the spring → the upper fixed support plate → the fixed steel plate → the main steel structure.

In summary, under the condition that the boundary structure of the large-span stay cable curtain wall is small in size, the deformation of the structure and the acting force of the load are considered, so that the application of the stay cable curtain wall is limited to a certain extent. In order to use the stay cable curtain wall system under the soft boundary condition, the stay cable curtain wall elastic adjusting system is developed for reducing the influence of the stay cable curtain wall on the structure. The system can absorb fluctuating and irregular dynamic loads, so that the overall safety and durability of the stay cable curtain wall and the fixing structure thereof are improved.

This application is according to the atress characteristics of cable curtain, and vertical cable has both born the dead weight load of glass panels, bears the wind load again, and compares with horizontal cable, and general span is all great. Therefore, the elastic adjusting device is arranged at the adjusting end of the vertical inhaul cable. The method is characterized in that:

the adjusting structure is arranged at the adjusting end of the vertical guy cable (the lower end of the vertical guy cable of the guy cable curtain wall). The span in the height direction of the curtain wall is larger. All be fixed in on the civil engineering structure around the vertical cable, and structure all around is the steel construction.

The utility model discloses mainly regard as the regulating element with the spring, the spring is hugged closely with lower movable support plate to fixed steel sheet, and the cable head is hugged closely with lower movable support plate disc simultaneously, forms a dynamic balance structure, under the load condition of cable curtain in the difference, has three kinds of operating modes. In the first working condition, when the cable is in a natural state, the spring and the tension of the stay cable form a natural balance state, the spring has certain compression and certain tension on the stay cable, and the spring and the stay cable are in a balance state in a natural state. Under the second working condition, when the wind load is large, the pulling force of the stay cable is enhanced, and the adjusting end of the stay cable drives the lower movable supporting plate to compress the spring, so that the spring is in a tightening state. And under the third working condition, when the wind load is further increased, the tension of the inhaul cable is enhanced, the spring reaches the maximum compression limit, the spring loses the adjusting effect and only serves as a force transmission component, and the load is completely transmitted to the structure. This regulation structure plays the effect of elastic adjustment under first kind and the second kind operating mode condition.
