As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In one embodiment of the present invention, as shown in fig. 1-2, a building structure 200 is provided. The building structure 200 includes a building 210 and a wing assembly 100, the wing assembly 100 is disposed on the top of the building 210 for reducing a horizontal overturning bending moment applied to the building 210, preventing the building 210 from vibrating due to an overturning tendency under a wind load, and improving a wind resistance of the building 210.
As shown in fig. 3 to 4, the wing assembly 100 includes a wing 10 and a bracket 30, the bracket 30 provides a mounting base for the wing 10, one end of the bracket 30 supports the wing 10, and a plane where the other end of the bracket 30 opposite to the wing 10 is located is a mounting surface a, and when the bracket 30 is arranged on the top of the building 210, the mounting surface a is coincident with the surface of the top of the building 210. The wing plate 10 comprises a windward front end 12 and a windward rear end 14 which are distributed along the incoming flow direction, and the height of the windward front end 12 relative to the installation surface a is smaller than that of the windward rear end 14 relative to the installation surface a; under the effect of the incoming flow flowing through the surface of the wing plate 10, the wing plate 10 bears the pressure directed to the support 30, and then the support 30 applies vertical pressure to the top of the building 210, so that the horizontal overturning bending moment of the high-rise building 210 under the effect of wind load is reduced, the vibration of the building 210 is dynamically inhibited, and the wind resistance of the building 210 is improved.
Wherein, the windward front end 12 of the wing plate 10 is lower than the windward rear end 14, which is just opposite to the arrangement mode of the common airplane wing, so as to form vertical pressure. Specifically, as shown in fig. 5-6, the cross section of the aircraft wing is a streamline, and when an incoming flow meets the wing with the cross section being the streamline, the incoming flow is divided into an upper stream and a lower stream, which respectively flow downward from the upper surface and the lower surface of the wing. According to the continuity theorem and Bernoulli's theorem in hydrodynamics, on the upper surface of the wing, the wing surface protrudes outwards to enable the flow pipe to contract, the flow speed is increased, and the pressure is reduced; on the lower surface of the wing, the flow tubes expand, the flow velocity decreases and the pressure increases. Therefore, the difference of the flow velocity of the airflows on the upper surface and the lower surface of the wing promotes pressure difference, the pressure on the upper surface of the wing is smaller than that on the lower surface, and upward lift force is formed on the wing.
The simplified estimation formula of the wing lift is shown as the formula (1):
wherein:
CLis the lift coefficient of the wing, lift coefficient CLRelating to parameters such as the shape of the cross section of the wing, the wind attack angle and the like;
0.5ρV2is the flight dynamic pressure of the airplane;
and S is the wing area.
The utility model provides a pterygoid lamina 10 as high-rise building's anti-wind part, according to above-mentioned wing lift principle, in other words with the wing inversion in building 210 top, forms pterygoid lamina 10 that provides reverse lift (pressure) to apply vertical wind pressure to high-rise building, and then reduce the overturning bending moment of high-rise building bottom under the wind load effect, improve building 210's anti-wind performance.
As shown in fig. 4, the wing plate 10 includes a first arc surface 11 and a second arc surface 13 both connected between a windward front end 12 and a windward rear end 14, the first arc surface 11 and the second arc surface 13 are oppositely arranged and are bent in a direction away from each other, so as to form the streamline wing plate 10, and after passing through the first arc surface 11 and the second arc surface 13 protruding outwards, pressure is formed on the wing plate 10.
In some embodiments, the first cambered surface 11 and the second cambered surface 13 are symmetrical relative to a connecting line b between the windward front end 12 and the windward rear end 14. It will be appreciated that in other embodiments, the first and second arcuate surfaces 11, 13 are asymmetrical with respect to the line b between the front and rear windward ends 12, 14; the first arc-shaped surface 11 is long in surface path in the incoming flow direction and faces the mounting surface a, and the second arc-shaped surface 13 is short in surface path in the incoming flow direction and faces away from the mounting surface a. So, first arcwall face 11 and second arcwall face 13 are asymmetric, and in the same time, the distance that the air current flows through first arcwall face 11 is longer, and the atmospheric pressure that descends in pterygoid lamina 10 below is more, and the atmospheric pressure of pterygoid lamina 10 top risees more, and the resultant force (vertical pressure) that pterygoid lamina 10 received is bigger, and the anti-wind effect is better.
As shown in fig. 2 to 4, the wing panel 10 extends in a longitudinal direction perpendicular to a line b between the windward front end 12 and the windward rear end 14 to form a long wing panel 10, so as to increase a contact surface of the wing panel 10 with an incoming flow and to generate a greater pressure.
Alternatively, the wing panel 10 can rotate around the longitudinal direction relative to the bracket 30 within a preset angle range to adjust the angle of the wing panel 10 relative to the mounting surface a, and the wing panel 10 can be adjusted to different angles to resist incoming flows with different intensities when the external airflow environment is different, so that the wind resistance intensity range of the wing panel 10 is wider. It is understood that in other embodiments, the wing plate 10 may be fixedly disposed on the bracket 30, and is not limited herein.
Moreover, the longitudinal direction of the wing panel 10 is parallel to the windward front edge 212 (as shown in fig. 2) at the top of the building 210, so that each position of the wing panel 10 in the longitudinal direction can be impacted by the incoming flow at approximately the same time, and the included angle between each position of the wing panel 10 in the longitudinal direction and the incoming flow is approximately consistent, so that the force applied to the wing panel 10 is relatively uniform.

In an embodiment of the present invention, there is further provided the wing plate assembly 100. The wing assembly 100 comprises a bracket 30 and a wing 10, wherein the bracket 30 provides a mounting base for the wing 10, one end of the bracket 30 supports the wing 10, the plane of the other end of the bracket 30, which is opposite to the wing 10, is a mounting surface a, and when the bracket 30 is arranged at the top of a building 210, the mounting surface a is superposed with the surface of the top of the building 210. The wing plate 10 comprises a windward front end 12 and a windward rear end 14 which are distributed along the incoming flow direction, and the height of the windward front end 12 relative to the installation surface a is smaller than that of the windward rear end 14 relative to the installation surface a; under the effect of the incoming flow flowing through the surface of the wing plate 10, the wing plate 10 bears the pressure directed to the support 30, and then the support 30 applies vertical pressure to the top of the building 210, so that the horizontal overturning bending moment of the high-rise building 210 under the effect of wind load is reduced, the vibration of the building 210 is dynamically inhibited, and the wind resistance of the building 210 is improved.
Under the action of wind load, the safety coefficient of overturning of the high-rise building 210 in the horizontal direction is shown in formula (2), and the parameters are shown in fig. 7.
In the formula:
l is the width of the building 210 in the incoming flow direction;
g is the building 210 deadweight;
FLthe pressure line load is disturbed by the wing plate 10;
l is the longitudinal length of the wing 10;
a is the distance between the turbulent flow pressure of the wing plate 10 and the leeward edge of the building 210;
b is the windward width of the building 210;
h is the building 210 height;
Fwjthe wind load linear density in the horizontal direction (including windward side and leeward side);
hjthe wind load linear density distribution height in the horizontal direction.
As can be seen from the above equation (2), the overturning safety factor is related to the structure of the building 210 itself and the turbulent pressure provided by the wing panel 10. Also, the greater the overturning safety factor, the stronger the wind resistance of the building 210. Therefore, the safety factor of the building 210 against overturning is increased when the wing panel 10 provides wind pressure resistance to the high-rise building 210.
