[0041] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention is now described with reference to the accompanying drawings.

[0042] The present invention provides a curved wind-driven curtain wall structure, such as Figure 1 , Figure 2 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 As shown, the curved pneumatic curtain wall structure comprises:

[0043] The vertical brackets 2 are arranged in a plurality of rows, the plurality of rows of the vertical brackets 2 are vertically arranged, the tops of the plurality of rows of the vertical brackets 2 are not flush, and the connecting lines of the top edges of the plurality of rows of the vertical brackets 2 form a first curve;

[0044] A plurality of pneumatic blade connection devices 4 are arranged on each column of vertical brackets 2 from top to bottom. A limiting device 6 is arranged on the pneumatic blade connection device. The limiting device includes a lateral limiting portion for limiting the translation of the pneumatic blade and a circumferential limiting portion for limiting the swing of the pneumatic blade.

[0045] Wind blade 5, such as Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, it is in sheet shape, and the material can be plastic, aluminum or aluminum alloy, steel sheet, and there are multiple wind blades, which are connected to the wind blade connecting device 4 through a limit device; multiple wind blades constitute a wind-driven curtain wall, and multiple wind blades are arranged on each vertical bracket, and each wind blade has the same size and structure and is independent of each other;

[0046] like Figure 7 , Figure 8 and Fig. 9 As shown, two first sleeves 50 are arranged at intervals and located on the same axis, connected to the top of the wind blade 5, and the axis of the first sleeve 50 is located in the same plane as the wind blade 5, and there is a spacing space 53 between the two intervals of the first sleeves 50 or there is a spacing between the two intervals of the first sleeves 50; the multiple first sleeves 50 in two adjacent rows are parallel to each other, but are not located on the same straight line, or are not flush; this makes the wind blades 5 in two adjacent rows unevenly arranged; it has a sense of layering and curves, and a better appearance; the whole wind blade 5 The body shape is, for example, a rectangle, so that the effect of the curve is more obvious and the sense of hierarchy is better; in addition, the plurality of wind blades are spaced apart from each other and independently arranged to form a matrix; or it can also be a curtain wall of triangular wind blades, a curtain wall of quadrilateral wind blades, a curtain wall of trapezoidal wind blades, a curtain wall of circular wind blades, etc.; all first sleeves 50 can be located in one plane, that is, all wind blades 5 are located in the same plane, but the edges of the wind blades 5 form a curve, so that the wind blades arranged in a plane give people a sense of a curved surface; so that the wind-driven curtain wall has a sense of a curved surface;

[0047] The swing shaft 55 has fixed connection parts at both ends and a rotating part between the fixed connection parts at both ends. The rotating part passes through the spacing space 53. The fixed connection part is connected to two first shaft sleeves 50 arranged at intervals and is fixedly connected to the two first shaft sleeves 50. The wind-actuated blade can swing with the wind through the connection of the swing shaft 55, and has low resistance, low wear and tear, and is durable.

[0048] like Figure 6 and Figure 7As shown, the lateral limiting part includes a second sleeve 60; the second sleeve 60 is located between the two-stage interval first sleeves 50, and the rotating part of the swing shaft 55 can be rotatably arranged in the second sleeve 60, for example, the swing shaft 55 rotates in the shaft hole 601 of the second sleeve 60, and the outer diameter of the first sleeve 50 is greater than the inner diameter of the second sleeve 60, and the first sleeve 50 of the two-stage interval is axially limited by the second sleeve 60, that is, the right end of the left first sleeve 50 is limited by the left end of the second sleeve 60, and the left end of the right first sleeve 50 is limited by the right end of the second sleeve 60. The above-mentioned lateral limiting part and circumferential limiting part can not only ensure that the wind blade 5 can swing, but also limit the lateral, i.e. axial movement of the wind blade 5, and also limit the swing range of the wind blade 5. Through the axial limiting between the sleeves, the wind blade 5 is subjected to uniform axial force and has strong wind resistance. In the case of wind blowing, it can move with the wind, but is not easy to twist and damage. The pneumatic blade connection device integrates connection, rotation, lateral limit and circumferential limit in one, with compact structure, firm connection, flexible swing and stable limit.

[0049] The distances between the swing shafts 55 at the top of the multiple columns of vertical brackets and the top edges of the multiple columns of vertical brackets are equal, and the connecting line of the swing shafts 55 at the top of the multiple columns of vertical brackets forms a second curve. The size and structure of each wind blade are the same. Therefore, the connecting line of the top edges of the wind blades at the top of the multiple columns of vertical brackets forms a second curve, and the connecting line of the bottom edges also forms a second curve. The second curve corresponds to the shape of the first curve. The connecting line of the midpoints of the second curve is the first curve, and the shape of the second curve is (basically) similar to or (basically) consistent with the shape of the first curve. In this way, the wind blades have a sense of curve and softness, which makes the top edge and bottom edge of the wind-driven curtain wall curved as a whole, that is, the present invention is a curved surface wind-driven curtain wall or a curved edge wind-driven curtain wall, which looks more beautiful.

[0050] Furthermore, if Figure 4 and Figure 5 As shown, the circumferential limit portion is connected to the lower part of the second sleeve 60; the circumferential limit portion includes a clamping device that forms a fixed angle and clamps on both sides of the pneumatic blade. The clamping device can be formed by two clamping edges and clamping surfaces that form an angle. The above-mentioned lateral limit portion and circumferential limit portion can not only ensure that the pneumatic blade 5 can swing, but also limit the lateral, i.e. axial, movement of the pneumatic blade 5, and can also limit the swing range of the pneumatic blade 5. This pneumatic blade connection device integrates connection, rotation, lateral limit and circumferential limit, and has a compact structure, firm connection, flexible swing and stable limit.

[0051] Furthermore, if Figure 3As shown, the cross-section of the vertical bracket is a rectangular hollow tube, such as aluminum profile or plastic steel, which is used to support the entire structure. The structure is light and easy to install and punch. A vertically arranged groove 7 is provided on the outer side of the vertical bracket for installing the pneumatic blade 5. The length direction of the vertical bracket is perpendicular to the axial direction of the swing shaft 55. The vertical bracket is clamped with multiple pneumatic blade connecting devices 4 through the groove 7.

[0052] Furthermore, if Fig.10 and Fig.11 As shown, the clamping device includes a first clamping surface 8 and a second clamping surface 14 clamped on both sides of the pneumatic blade, the first clamping surface 8 and the second clamping surface 14 form a V-shaped opening, and the axis of the first sleeve 50 is parallel to the first clamping surface 8 and the second clamping surface 14. The clamping device is composed of, for example, a first clamping plate 61 and a second clamping plate 63 that form an angle. The first clamping surface 8 is the inner side surface of the first clamping plate 61, and the second clamping surface 14 is the inner side surface of the second clamping plate 63. In this way, the clamping area or limiting area for the swing of the pneumatic blade 5 is large, and the pneumatic blade 5 is not easy to twist and damage. The width W of the lateral limiting portion, i.e., the second sleeve 60, is equal to the width of the circumferential limiting portion, i.e., the two clamping plates, and is also equal to the width of the cross beam 9 and the vertical beam 10. In this way, it is convenient to process and manufacture the limiting device 6 in an integrated manner. For example, the limiting device 6 is made of plastic steel or aluminum alloy or steel through a mold in an integrated manner.

[0053] A hollow triangular or fan-shaped space is formed between the first clamping surface 8 and the second clamping surface 14; the triangular or fan-shaped space limits the wind blade to swing only within the angle of the fan in the swinging state, so that the wind blade can only swing circumferentially within a certain angle, which increases stability. The wind blade is vertically downward under the action of gravity when it is stationary, ensuring the beauty of the wind-driven curtain wall; the entire curtain wall can be kept flat and the structure is stable and durable in a windless state. The angle between the first clamping surface 8 and the second clamping surface 14 is an acute angle, which can be between 30 degrees and 60 degrees, for example, 30 degrees, 45 degrees, and 60 degrees, so as to control the swing of the wind blade 5 within the range of gentle swinging, and prevent the wind blade 5 from swinging too much when the wind is too strong, thereby damaging the wind blade 5.

[0054] Furthermore, the pneumatic blade connection device 4 includes a fixed portion connected to the vertical bracket and an extended portion extending outward from the horizontal bracket, the extended portion has an outer end and an inner end, the inner end of the extended portion is connected to the fixed portion, the pneumatic blade is connected to the outer end of the extended portion, and a limit device is arranged at the outer end of the extended portion, leaving sufficient swing space for the pneumatic blade 5.

[0055] Furthermore, the fixed part and the extended part are connected to form an L-shaped structure located in a vertical plane, wherein the fixed part includes a vertical beam 10, and the extended part includes a horizontal beam 9; the vertical beam 10 is clamped in the groove 7 of the vertical bracket, and the width of the horizontal beam 9 is equal to the width of the vertical beam 10, so that both the horizontal beam 9 and the vertical beam 10 can be clamped in the groove 7 of the vertical bracket, and the connection is stable. Moreover, during installation, the entire wind blade connection device 4 can be vertically moved along the groove 7, and the positioning is accurate and the installation is convenient. In order to further increase the stability, a screw or rivet passing through the connection hole 101 is also connected between the vertical beam 10 and the vertical bracket.

[0056] Furthermore, if Fig. 9 As shown, the top of the wind blade 5 is provided with a rectangular opening 57, the length of the rectangular opening 57 is equal to the spacing distance between the two first sleeves 50 spaced apart, the rectangular opening 57 has two parallel side walls and a bottom wall connected between the two parallel side walls, and the bottom wall is parallel to the axis of the first sleeve 50, as shown in FIG. Fig.11 As shown, the distance D between the axis of the first sleeve 50 and the bottom wall is greater than the outer diameter L of the first sleeve 50. Through the rectangular opening 57, the pneumatic blade 5 can swing freely and achieve position limiting.

[0057] Furthermore, if Figure 1 , Figure 2 , Fig.14 , Fig.15 , Fig.16 As shown, the first curve is an arc or a wavy line, which is more beautiful, has a better sense of tortuosity, and is soft.

[0058] Furthermore, if Figure 1 , Figure 2 , Fig.14 , Fig.15 , Fig.16 As shown, among the swing shafts 55 at the top of the multiple columns of the vertical brackets, the height difference between the two columns of swing shafts 55 at the top of any adjacent vertical brackets is a constant value, and on the same vertical bracket, the height difference between the two adjacent rows of swing shafts 55 is a constant value. In particular, when the first curve is an arc or a wavy line, the height difference between the two adjacent rows of swing shafts 55 is a constant value, so that the connecting line of the top edges of the wind blades at the top of the multiple columns of the vertical brackets and the connecting line of the bottom edges form a relatively uniform or gradient rise or fall, which is not abrupt.

[0059] Furthermore, if Fig.15 and Fig.16As shown, the height difference between two adjacent rows of swing shafts 55 is greater than or equal to the diameter of the first sleeve 50 or less than the diameter of the second sleeve 60, so that the height difference between the connecting line of the top edge of the wind blades at the top of the adjacent vertical brackets and the bottom edge is greater than or equal to the diameter of the first sleeve 50 or less than the diameter of the second sleeve 60. The value between the diameter of the cylindrical first sleeve 50 and the diameter of the second sleeve 60 is used as the height difference between adjacent wind blades, so that the gradient difference between adjacent wind blades will not be too large to expose the sheet-like parts of the wind blades, forming the adjacent first sleeves 50 or second sleeves 60 or adjacent wind blades too loose, and the difference is not too small, so that the gradient difference between adjacent wind blades will not be too small to form the adjacent first sleeves 50 or second sleeves 60 or adjacent wind blades too crowded or too dense. The height difference between two adjacent rows of swing shafts 55 is equal to the value between the diameter of the first sleeve 50 and the diameter of the second sleeve 60. This difference just makes the connection between adjacent first sleeves 50 or adjacent wind blades form a natural connection. For example, from Fig.15 and Fig.16 As shown, the adjacent first sleeves of each vertical bracket form a compact stacking arrangement, and the clamping device formed by the first clamping plate and the second clamping plate of the adjacent limiting device of each vertical bracket also forms a compact superposition. In this way, when viewed from the main viewing direction, the gradient of the second curve, especially the arc or wavy line, is softer; when viewed from the side, the adjacent first sleeves and the clamping devices of each vertical bracket form a side superposition effect, and the sense of hierarchy is better.

[0060] Furthermore, if Figure 1 and Figure 2 As shown, the pneumatic curtain wall structure also includes: two rows of parallel transverse brackets 3 connected to the inner side of each vertical bracket, wherein one row of transverse brackets is connected to the top of each vertical bracket by, for example, clamping or bolting, and the other row of transverse brackets is connected to the bottom of each vertical bracket by clamping or bolting. The transverse brackets 3 can be set on the wall, and the transverse brackets 3 are all hollow pipes, such as aluminum profiles or plastic steel, providing flat support for each vertical bracket, which is convenient to install and has a firm structure; it is light in weight and easy to install and punch.

[0061] The above technical solution has the following beneficial effects: the curved pneumatic curtain wall structure can be connected to the wall through a vertical bracket or a horizontal bracket and installed on the wall; the pneumatic blade 5 is vertically downward under the action of gravity when it is stationary, and in the case of wind, the pneumatic blade 5 can only swing circumferentially within a certain angle, and is limited by the first clamping surface on the left side, and swings to the maximum angle on the left side, and is limited by the second clamping surface on the right side, and swings to the maximum angle on the right side. Moreover, when limiting, the first clamping surface 8 limits the pneumatic blade 5 in surface contact, and the inner wall of the first clamping surface 8 and the outer side surface of the pneumatic blade 5 overlap each other, so that the stability of the limit is achieved.

[0062] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. The components of the present invention can be combined with each other without conflict, and any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention.
