Problems solved by technology

When the wind force is small, usually less than 15 m / s, it will cause micro-vibration of high-rise buildings, and the amplitude can reach several centimeters. Under the action of the wind, fatigue damage will be caused, and finally the entire enclosure structure will cause accidents, and as the wind force continues to increase, vortices will be generated in the direction perpendicular to the wind force, and will fall off alternately at a certain frequency. Generate large vortex induced vibration, which will cause great damage to the envelope structure of high-rise buildings that have not been fully constructed

Embodiment 1

[0033] A wind-resistant device for high-rise building construction, the details are as follows:

[0034] refer to figure 1 , the number of mounting substrates 6 is two, and the angle of the two outer mounting substrates 6 is the same as that of the high-rise building envelope, and is installed on both sides of the high-rise building envelope by bolts.

[0035] Under normal circumstances, the wall angle of a building is usually 90°. In this embodiment, a wall angle of 90° is taken as an example, and the angle between the two mounting substrates 6 is also 90°. The means are installed at the corner of the wall.

[0036] refer to figure 1 The angle of the L-shaped frame 1 is the same as the angle formed by the two mounting substrates 6. In this embodiment, the mounting substrate 6 is 90°, and the included angle of the L-shaped frame 1 (also called a turning angle) is also 90°.

[0037] refer to figure 1 , In this embodiment, the flexible connecting member 8 can use a spring, r...

Embodiment 2

[0057] refer to Figure 1-4 , a high-rise building construction wind resistance device, the present embodiment is further provided with a permanent magnet 9 on the basis of the first embodiment, the permanent magnet 9 is arranged at the position corresponding to the movable plate 2 and the opening 3, and the connecting block 51 adopts a ferromagnetic material.

[0058] The arrangement of the permanent magnets 9 makes the permanent magnets 9 and the connection block 51 connect more closely and stably together, and it is not easy to be easily separated, so that the shock-absorbing member 5 can absorb the vibration energy more stably, and it is easier to make the shock-absorbing member 5 more stably absorb the vibration energy. The vibration element 5 locks the vibration frequency of the movable plate 2 .

Abstract

The invention discloses a wind resistance device for high-rise building construction, and relates to the technical field of building construction devices, comprising an installation base plate, the angle of the L-shaped frame is the same as the angle formed by the two installation base plates; The ends are respectively fixedly connected with the mounting base plate and the L-shaped frame; when one of the movable plates moves to the side close to the L-shaped frame, the other movable plate moves to the side away from the L-shaped frame under the transmission of the fixed-angle transmission mechanism; The shock-absorbing element is arranged on the mounting base plate; the shock-absorbing element does not contact the movable plate under the action of external force, and the movable plate moves toward the side close to the L-shaped frame and contacts the shock-absorbing element when the movement reaches the limit. The present invention utilizes aerodynamics. By arranging the movable plate and the fixed-angle transmission mechanism matched with it, when the movable plate parallel to the wind direction is lifted, the movable plate perpendicular to the wind direction can contact the shock-absorbing member to achieve shock absorption, and When the wind direction changes, the two movable plates can also change the wind direction to reduce the vortex-induced vibration.

Description

technical field [0001] The invention relates to the technical field of building construction devices, in particular to a wind-resistant device for high-rise building construction. Background technique [0002] High-rise buildings will produce so-called breeze vibration under the action of wind. When the wind force is small, usually less than 15 m / s, it will cause micro-vibration in high-rise buildings, and the amplitude can reach several centimeters. Under the action of the wind, it will cause fatigue damage, and finally cause the entire enclosure structure to cause an accident, and with the continuous increase of the wind force, vortices will be generated in the direction perpendicular to the wind force, and they will fall off alternately at a certain frequency. Larger vortex-induced vibrations are generated, which will cause greater damage to the envelope structure of high-rise buildings that have not been fully constructed. SUMMARY OF THE INVENTION [0003] The purpos...
