Further, the truss 40 includes a first beam 41, a second beam 42 and a triangular steel frame 43, the second beam 42 is parallel to the first beam 41 and is disposed at an interval, the triangular steel frame 43 is connected between the first beam 41 and the second beam 42, and the top end 13 of the curtain 10 is fixedly disposed on the first beam 41.

In this embodiment, because city canopy is mostly set up in the open air, like seaside, lake, river etc., consequently, this city canopy 100 will probably receive the wind pressure effect that comes from different directions, when this city canopy 100 receives the wind pressure effect, should cover the plane back and forth swing of portion 122 relative this curtain 10 to expose this hole 11 of preventing wind, thereby make wind can be through this hole 11 of preventing wind, reduce the wind pressure that this city canopy 100 bore, and then strengthen this city canopy 100's stretching resistance, avoid the emergence of incident.

In this embodiment, the curtain 10 may be composed of a first surface layer 10a, a fiber layer 10b and a second surface layer 10c, which are sequentially stacked, and a plurality of fibers in the fiber layer 10b are orthogonally arranged to form a warp-weft structure, so that the tension of the curtain 10 can be effectively enhanced, and a good anti-tearing effect is ensured. As shown in fig. 3, in order to avoid the situation that the warp and weft structures in the fiber layer 10b are damaged when the wind-proof holes 11 are formed in the curtain 10, and the tension of the curtain 10 is reduced, when the wind-proof holes 11 are formed, the wind-proof holes 11 may be sequentially and equidistantly arranged according to the weft lines L1 in the warp and weft structures in the length extending direction of the curtain 10, and the wind-proof holes 11 may be sequentially and equidistantly arranged according to the warp lines L2 in the width extending direction of the curtain 10, and the centers of the wind-proof holes 11 are all located at the intersections 101 of the weft lines L1 and the warp lines L2, so as to effectively avoid the damage of the warp and weft structures in the fiber layer 10b, ensure the tensile resistance of the curtain 10, and further enhance the wind pressure resistance of the urban sky curtain 100.

Referring to fig. 2 and 5, in the present embodiment, the connecting portion 121 can be integrally formed with the curtain 10, for example, when the connecting portion 121 is integrally formed with the curtain 10, a connecting track 121a between the connecting portion 121 and the curtain 10 can be a straight line, an arc line, a wavy line or a zigzag line (as shown in fig. 5). It is understood that the connection portion 121 may also be removably connected to the curtain 10 in other embodiments. For example, the connecting portion 121 may be adhered to the curtain 10 by means of glue, or the connecting portion 121 may be sewn to the curtain 10 by means of sewing threads.

Further, when the connecting portion 121 is connected to the curtain 10, at least a highest point of the connecting portion 121 connected to the curtain 10 is located at a position where the connecting portion is less than a distance from the covering portion 122 to the top end 13, so that when the city canopy 100 is unfolded, the covering portion 122 can cover the windproof hole 11 under the action of gravity, that is, when the curtain 10 applied to the city canopy 100 is not under the action of wind pressure or under the action of small wind pressure, the covering portion 122 can cover the windproof hole 11, so that the curtain 10 can maximally ensure the flatness of the curtain 10, and further can provide a better image display effect on the curtain 10 during performance. In addition, when this city canopy of sky received great wind pressure to act on, this cover portion 122 can be in this hole 11 of preventing wind swing back and forth relatively this connecting portion 121 to make wind pass through in can following the hole 11 of preventing wind, reduce the wind pressure that the city canopy of sky bore, and then the stretching resistance of reinforcing city canopy of sky reduces the emergence of incident.

Referring to fig. 2, fig. 6 to fig. 9, in the present embodiment, in order to facilitate the formation of the wind-proof hole 11 and the covering of the wind-proof hole 11 by the covering portion 122, the curtain 10 may be cut along a predetermined track to form the covering portion 122, and the wind-proof hole 11 is formed in an area between the predetermined track and the connecting portion 121. It should be understood that the pattern of the predetermined track must be adapted to the shape of the covering portion 122, that is, when designing the covering portion 122, a predetermined track matching the shape of the covering portion 122 can be pre-designed on the curtain 10, and then the covering portion 122 is cut on the curtain 10 according to the predetermined track. Since the covering portion 122 is formed by cutting on the curtain and the covering portion 122 is used for covering the windproof hole 11, the area between the predetermined track and the connecting portion 121 is the area where the windproof hole 11 is located, that is, the area between the predetermined track and the connecting portion 121 forms the windproof hole 11. It can be appreciated that the cover portion 122 has a shape and size that corresponds to the shape and size of the windproof opening 11.

Further, in order to ensure that the imaging effect and the wind pressure resistance effect of the curtain 10 can be effectively ensured after the wind-proof hole 11 is formed in the curtain 10, the wind-proof hole 11 may be in an inverted trapezoid shape, a U shape, an approximate bowl-shaped structure or an approximate feather ball-shaped structure (as shown in fig. 6), and since the shape and the size of the covering portion and the wind-proof hole are the same, the covering portion 122 is also in an inverted trapezoid shape, a U shape, an approximate bowl-shaped structure or an approximate feather ball-shaped structure.

Preferably, in order to ensure the flatness of the curtain 10 applied to the city canopy 100 when not subjected to wind pressure or when the wind pressure is small, so as to have a good image forming effect, the wind-proof holes 11 may preferably be inverted isosceles trapezoid-shaped holes, that is, the cross-sectional shape of the wind-proof holes 11 along a plane parallel to the curtain is inverted isosceles trapezoid. Since the shape of the wind-proof hole 11 is identical to the shape of the cover portion 122, the cross-sectional shape of the cover portion 122 parallel to the curtain is also an inverted isosceles trapezoid.

Furthermore, the inverted isosceles trapezoid is formed by enclosing an upper base a, a first side b, a lower base c and a second side d in sequence. Since the covering portion 122 is cut on the curtain 10 according to a predetermined track, and the wind-proof hole 11 is formed in the area between the predetermined track and the connecting portion 121 after cutting, that is, the predetermined track is the track formed by the second side d, the upper bottom a and the first side b, the connecting track 121a between the connecting portion 121 and the curtain 10 is the lower bottom c of the inverted isosceles trapezoid. In addition, in order to enhance the tearing resistance at the joint of the lower base c and the first side b and the joint of the lower base c and the second side d, a first tearing-prevention structure is arranged between the first side b and the lower base c, and a second tearing-prevention structure is arranged between the second side d and the lower base c.

Furthermore, the first anti-tear structure and the second anti-tear structure can be both convex arc structures. As shown in fig. 7, the one end of this first anti-tear structure is connected with this first side b, the other end of this first anti-tear structure is connected with this c of going to the bottom, thereby form first arc transition structure 15 between this first side b and this c of going to the bottom, the one end of this second anti-tear structure is connected with this second side d, the other end of this second anti-tear structure is connected with this c of going to the bottom, thereby form second arc transition structure 16 between this second side d and this c of going to the bottom, and then when city day curtain received great wind pressure effect, can strengthen the anti-tear ability of connecting portion 121 tip of being connected with curtain 10 in this shielding member 12, thereby effectively reduce the probability that the damage condition appears tearing when receiving strong wind pressure to the curtain.

Preferably, the first anti-tear structure and the second anti-tear structure may also be circular through holes, as shown in fig. 8, the first side b is connected to the first anti-tear structure, and the lower bottom c is connected to the first anti-tear structure, so that a first concave arc-shaped gap 15a may be formed between the first side b and the lower bottom c; this second side d prevents tearing the structural connection with this second, this go to the bottom c and this second prevent tearing the structural connection, thereby can form second concave arc breach 16a between this second side d and this c of going to the bottom, and then when the city sky curtain receives great wind pressure to act on, connecting portion 121 of being connected with curtain 10 will receive equal wind pressure effect, and this circular through-hole dispersable acts on the wind pressure of this connecting portion 121 tip, thereby reduced the tearing of wind to this connecting portion 121 tip, the ability of tearing resistance of this connecting portion 121 tip has been strengthened.

Further, the sum of the areas of all the windproof holes 11 on the curtain 10 is 60-80% of the plane area of the curtain 10. That is, when the wind-proof holes 11 are inverse trapezoidal holes disposed on the curtain 10, the sum of the areas of all the inverse trapezoidal holes is 60% to 80% of the planar area of the curtain 10. By adopting the design, the air passing amount of the wind-proof holes in the curtain 10 can be effectively ensured, the wind pressure resistance effect of the curtain is ensured, meanwhile, the tension of the curtain 10 can be effectively ensured, and the imaging effect of the curtain can be effectively ensured when imaging is performed.

Preferably, the sum of the areas of all the windproof holes 11 on the curtain 10 is 68% of the planar area of the curtain 10. It is understood that in other embodiments, the sum of the areas of all of the louvers 11 in the curtain 10 can be 60%, 65%, 70%, 72%, 75%, 78%, or 80% of the planar area of the curtain 10.

In this embodiment, as shown in fig. 9, when the city canopy is subjected to wind pressure, the covering portion 122 connected to the curtain 10 swings back and forth along with the wind direction due to the wind pressure equal to that of the city canopy, and at this time, the wind-proof hole 11 covered by the covering portion 122 is exposed due to the swing of the covering portion 122, so that the wind can pass through the wind-proof hole 11, the wind pressure borne by the city canopy is reduced, and the wind pressure resistance of the city canopy is further enhanced.

In this step, the curtain 10 is the curtain 10 in the first embodiment, wherein the curtain 10 may be composed of a first surface layer 10a, a fiber layer 10b and a second surface layer 10c, which are sequentially stacked, and a plurality of fibers in the fiber layer 10b are orthogonally arranged to form a warp-weft structure, so that the tension of the curtain 10 can be effectively enhanced, and a good anti-tearing effect is ensured.

S2: set up a plurality of windproof holes 11 and correspond a plurality of shielding parts 12 of these windproof holes 11 setting on this curtain 10, each shielding part 12 includes connecting portion 121 and with the cover portion 122 of this connecting portion 121 rigid coupling, this connecting portion 121 fixed connection in this curtain 10, each cover portion 122 all covers each windproof hole 11.

In this step, as shown in fig. 3, in order to avoid the situation that the warp and weft structure in the fiber layer 10b is damaged when the wind-proof holes 11 are formed in the curtain 10, and the tension of the curtain 10 is reduced, when the wind-proof holes 11 are provided, the wind-proof holes 11 are sequentially and equidistantly arranged according to the weft L1 in the warp and weft structure in the length extending direction of the curtain 10, the wind-proof holes 11 are sequentially and equidistantly arranged according to the warp L2 in the width extending direction of the curtain 10, and the center of each wind-proof hole 11 is located at the intersection 101 of the weft L1 and the warp L2, so that the warp and weft structure in the fiber layer 10b is effectively prevented from being damaged, the tensile resistance of the curtain is ensured, and the wind pressure resistance of the urban sky curtain is enhanced.

Of course, in this step, the connecting portion 121 may be integrally formed with the curtain 10, for example, when the connecting portion 121 is integrally formed with the curtain 10, the connecting track 121a of the connecting portion 121 and the curtain 10 may be a straight line, an arc line, a wavy line or a zigzag line (as shown in fig. 4). It is understood that the connection portion 121 may also be removably connected to the curtain 10 in other embodiments. For example, the connecting portion 121 may be adhered to the curtain 10 by means of glue, or the connecting portion 121 may be sewn to the curtain 10 by means of sewing threads.

Further, the curtain 10 includes a top end 13 and a bottom end 14, which are oppositely disposed, that is, when the curtain 10 is hung on a truss, the top end of the curtain 10 is the end fixedly connected to the truss, and the bottom end of the curtain 10 is the end hanging from the ground. When the connecting portion 121 is connected to the curtain 10, the distance from at least one highest point to the top end 13 at the position where the connecting portion 121 is connected to the curtain 10 is smaller than the distance from the covering portion 122 to the top end 13, so that when the curtain is unfolded (i.e., the curtain is hung on a truss), the covering portion 122 can cover the windproof hole 11 under the action of gravity, that is, when the curtain 10 applied to the outdoor city awning 100 is not subjected to the action of wind pressure or is subjected to the action of small wind pressure, the covering portion 122 can cover the windproof hole 11, so that the curtain 10 can maximally ensure the flatness of the curtain 10, and further, a better image display effect can be presented on the curtain 10 during performance. In addition, when the city canopy 100 is subjected to a large wind pressure, the covering portion 122 swings back and forth in the wind-proof hole 11 relative to the connecting portion 121, so that wind can pass through the wind-proof hole 11, wind pressure borne by the city canopy 100 is reduced, tensile resistance of the city canopy 100 is enhanced, and safety accidents are reduced.

Referring to fig. 1, fig. 5 to fig. 7, in the present embodiment, a plurality of windproof holes 11 are disposed on the curtain 10, and a plurality of shielding members 12 are disposed corresponding to the windproof holes 11, and each shielding member 12 includes a connecting portion 121 and a covering portion 122 fixedly connected to the connecting portion 121, which specifically includes the following steps:

s21: and setting a preset track.

In this step, the pattern of the predetermined track must be adapted to the shape of the covering portion 122, that is, the predetermined track matching the shape of the covering portion 122 is designed on the curtain 10 in advance.

S22: the curtain 10 is cut along a predetermined track to form the covering portion 122, and the wind-proof hole 11 is formed in the region between the predetermined track and the connecting portion 121.

Specifically, in this step, the covering portion 122 is cut and formed on the curtain 10 according to the preset trajectory. Since the covering portion 122 is formed by cutting on the curtain and the covering portion 122 is used for covering the windproof hole 11, the area between the predetermined track and the connecting portion 121 is the area where the windproof hole 11 is located, that is, the area between the predetermined track and the connecting portion 121 forms the windproof hole 11, it can be known that the shape and size of the covering portion 122 are the same as the shape and size of the windproof hole 11.

Further, in order to ensure that the imaging effect and the wind pressure resistance effect of the curtain 10 can be effectively ensured after the wind-proof hole 11 is formed in the curtain 10, the wind-proof hole 11 may be in an inverted trapezoid shape, a U shape, an approximate bowl-shaped structure or an approximate feather ball-shaped structure (as shown in fig. 5), and since the shape and the size of the covering portion and the wind-proof hole are the same, the covering portion is also in an inverted trapezoid shape, a U shape, an approximate bowl-shaped structure or an approximate feather ball-shaped structure.

Preferably, in order to ensure the flatness of the curtain 10 applied to the city canopy 100 when not subjected to wind pressure or when the wind pressure is small, so as to have a good image forming effect, the wind-proof holes 11 may preferably be inverted isosceles trapezoid-shaped holes, that is, the cross-sectional shape of the wind-proof holes 11 along a plane parallel to the curtain 10 is inverted isosceles trapezoid. Since the shape of the wind-proof hole 11 is identical to the shape of the cover portion 122, the cross-sectional shape of the cover portion 122 parallel to the curtain is also an inverted isosceles trapezoid.

Furthermore, the first anti-tear structure and the second anti-tear structure can be both convex arc structures. As shown in fig. 6, the one end of this first anti-tear structure is connected with this first side b, the other end of this first anti-tear structure is connected with this c of going to the bottom, thereby form first arc transition structure 15 between this first side b and this c of going to the bottom, the one end of this second anti-tear structure is connected with this second side d, the other end of this second anti-tear structure is connected with this c of going to the bottom, thereby form second arc transition structure 16 between this second side d and this c of going to the bottom, and then when city day curtain received great wind pressure effect, can strengthen the anti-tear ability of connecting portion 121 tip of being connected with curtain 10 in this shielding member 12, thereby effectively reduce the probability that curtain 10 appeared tearing the damage condition when receiving strong wind pressure.

Preferably, the first anti-tear structure and the second anti-tear structure may also be circular through holes, as shown in fig. 7, the first side b is connected to the first anti-tear structure, and the lower bottom c is connected to the first anti-tear structure, so that a first concave arc-shaped gap 15a may be formed between the first side b and the lower bottom c; this second side d prevents tearing the structural connection with this second, this go to the bottom c and this second prevent tearing the structural connection, thereby can form second concave arc breach 16a between this second side d and this c of going to the bottom, and then when the city sky curtain receives great wind pressure to act on, connecting portion 121 of being connected with curtain 10 will receive equal wind pressure effect, and this circular through-hole dispersable acts on the wind pressure of this connecting portion 121 tip, thereby reduced the tearing of wind to this connecting portion 121 tip, the ability of tearing resistance of this connecting portion 121 tip has been strengthened.

In the second embodiment of the present invention, a preset track is designed in advance on the curtain 10, and then the curtain 10 is cut according to the preset track to form the covering portion 122, and the windproof hole 11 is formed in the area between the preset track and the connecting portion 121. In this way, the windproof holes 11 and the covering portion 122 can be conveniently and quickly formed on the curtain 10.

According to the urban canopy, the wind-proof holes are formed in the curtain, the shielding pieces are arranged corresponding to the wind-proof holes, the connecting parts of the shielding pieces are connected with the curtain, and the shielding parts of the shielding pieces cover the wind-proof holes, so that when the urban canopy is subjected to wind pressure, the shielding parts can swing back and forth relative to the connecting parts, wind passes through the wind-proof holes, the wind pressure borne by the urban canopy is reduced, and the urban canopy is prevented from being damaged by strong wind pressure. In addition, when city canopy does not receive the wind pressure or the wind pressure that receives is less, the portion of hiding covers completely prevent wind hole to can effectively ensure the imaging effect of city canopy.
