Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a perforated folding plate sunshade system. Background Technology

[0002] In the summer afternoons when the sun's angle is low, strong direct sunlight can shine extensively onto the west wall and windows of the factory building. Sunshades reduce the accumulation of heat entering the building by blocking direct sunlight, preventing overheating in localized areas.

[0003] Currently, traditional factory sunshades typically use flat, perforated panels. When sunlight shines on the sunshade, some of it passes through the perforations and directly onto the west wall of the factory. This results in the shading rate of traditional flat, perforated structures being only 60%-70%, causing a sudden increase in the temperature of the west wall, exceeding 50°C. To address this, Chinese utility model patent CN 222782268 U provides a three-dimensional perforated panel for building facades and a glass curtain wall incorporating it. The panel includes a base plate with several holes. Each hole has a folded edge around its perimeter on the light-facing surface. The folded edge blocks the perforations to achieve a higher shading rate. However, considering factory ventilation and lighting issues, the folded edge size, hole size, and opening ratio cannot be too small, limiting the effectiveness of this solution in improving shading.

[0004] Therefore, how to improve the shading rate of factory sunshades while ensuring indoor ventilation has become an urgent problem to be solved. Utility Model Content

[0005] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a perforated folding plate sunshade system to effectively improve the sunshade and ventilation effects of factory buildings.

[0006] To achieve the above-mentioned utility model objectives, this utility model provides a perforated folding plate sunshade system, including multiple sets of unit-type sunshade panels and a bracket system for fixing the unit-type sunshade panels to a wall. The unit-type sunshade panel includes:

[0007] A plurality of folding plate units are connected in sequence. Each folding plate unit includes a first sunshade, a second sunshade, and a third sunshade connected in sequence. The first sunshade and the second sunshade, and the second sunshade and the third sunshade, form an angle. The first sunshade, the second sunshade, and the third sunshade are provided with sunshade ventilation holes that penetrate the surface of the sunshade. The sunshade ventilation holes are asymmetrical holes, and the upper end of the sunshade ventilation holes has at least one narrow end.

[0008] Two connecting plates are respectively set on one side of the first folding plate unit and the last folding plate unit.

[0009] According to one technical solution of this utility model, the support system includes:

[0010] The embedded part is L-shaped, with one end fixed inside the wall and the other end set on the wall surface;

[0011] Purlins are fixedly connected to the embedded parts;

[0012] Fasteners for connecting the connecting plate and the purlin.

[0013] According to one technical solution of this utility model, the sunshade ventilation hole is a lightning bolt-shaped hole or a windmill-shaped hole.

[0014] According to one technical solution of this utility model, the opening ratio of the folding plate unit is greater than 35%.

[0015] According to one technical solution of this utility model, the upper end of the folding plate unit is provided with a flange, which is disposed on the side of the folding plate unit facing away from the wall and protrudes along the side of the folding plate unit.

[0016] According to one technical solution of this utility model, the maximum distance between the folding plate unit and the wall is not less than 200mm.

[0017] According to one technical solution of this utility model, the included angle of the sunshade in several of the folding plate units is the same, and is not less than 30°.

[0018] According to one technical solution of this utility model, the sunshade angles of two adjacent folding plate units in the plurality of folding plate units are different, and the smallest sunshade angle is not less than 30°.

[0019] According to one technical solution of this utility model, an anti-wear component is provided between the purlin and the connecting plate.

[0020] According to one technical solution of this utility model, the edge of the sunshade ventilation hole is rounded.

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] This utility model provides a perforated folded plate sunshade system. The unit-type sunshade includes multiple folded plate units connected in sequence. Each folded plate unit consists of three sunshade plates. Adjacent sunshade plates have an included angle, making the cross-section of the unit-type sunshade plate corrugated, which improves the diffuse reflection of sunlight on the sunshade plate in summer and reduces the direct sunlight rate. The sunshade plate is provided with sunshade ventilation holes, which are asymmetrical holes with narrow ends at the top, further reducing the direct sunlight rate of the west wall refracted by the sunshade plate in the afternoon, thereby improving the shading efficiency of the sunshade system.

[0033] The description of the embodiments in this specification should be taken in conjunction with the accompanying drawings, which should form part of the complete specification. In the drawings, the shape or thickness of the embodiments may be exaggerated and may be indicated in a simplified or convenient manner. Furthermore, parts of the various structures in the drawings will be described separately; it is worth noting that elements not shown in the figures or not described in words are in a form known to those skilled in the art.

[0034] The description of the embodiments herein, including any references to direction and orientation, is for ease of description only and should not be construed as limiting the scope of protection of this utility model. The following description of preferred embodiments involves combinations of features, which may exist independently or in combination; this utility model is not particularly limited to the preferred embodiments. The scope of this utility model is defined by the claims.

[0035] like Figure 1-5 As shown, this utility model provides a perforated folding plate sunshade system, including multiple sets of unit-type sunshade panels 1 and a support system 2. The support system 2 is used to fix the unit-type sunshade panels 1 to the wall surface 3. The unit-type sunshade panel 1 includes several folding plate units 11 connected in sequence and two connecting plates 12. Each folding plate unit 11 includes a first sunshade panel 111, a second sunshade panel 112, and a third sunshade panel 113 connected in sequence. The first sunshade panel 111 and the second sunshade panel 112, and the second sunshade panel 112 and the third sunshade panel 113 form an angle. The first sunshade panel 111, the second sunshade panel 112, and the third sunshade panel 113 are provided with sunshade ventilation holes that penetrate the surface of the sunshade panel. The sunshade ventilation holes are asymmetrical holes, and the upper end of the sunshade ventilation holes has at least one narrow end. The two connecting plates 12 are used to connect to the support system 2, and the two connecting plates 12 are respectively located on one side of the first folding plate unit and on one side of the last folding plate unit.

[0036] By setting asymmetrical shading ventilation holes on the sunshade panel, with at least one narrow end at the top of the ventilation hole, the sunshade panel has sufficient ventilation channel area, while the narrow end and asymmetrical shape of the ventilation hole block the direct sunlight from the west, reducing the sunlight transmission rate and improving the shading effect. At the same time, the folding plate unit is composed of multiple sunshade panels with included angles, and the cross-section of the sunshade panel is wavy, which effectively improves the diffuse reflection of sunlight, thereby blocking the direct sunlight and reflected light.

[0037] The above solution achieves highly efficient shading, with a shading rate of up to 88% in summer and 75% in winter, reducing the temperature of the west wall by 8-10℃. Simultaneously, the asymmetrical shading ventilation holes optimize ventilation, reducing airflow loss by nearly 12% and maintaining an air exchange rate of over 6 times per hour, effectively improving the factory's ventilation performance.

[0038] In one embodiment of this utility model, the support system 2 includes an embedded part 21 and a purlin 22. The embedded part 21 is L-shaped, with one end fixed inside the wall and the other end set on the wall surface. The purlin 22 is fixedly connected to the embedded part 21. In this embodiment of the utility model, the purlin 22 can be an angle steel bracket with a diameter of ∠50×50×50mm, fixedly connected to the embedded part 21 by full welding or bolts or other connecting parts. When fully welded to the embedded part 21, the weld length is not less than 50mm, which is used to improve the connection strength between the purlin 22 and the embedded part 21. Fastener 23 is used to connect connecting plate 12 and purlin 22. Fastener 23 can be an M8×30mm stainless steel bolt. Bolt holes are provided on connecting plate 12 and purlin 22. The bolt holes on connecting plate 12 and purlin 22 can be set as 20mm elongated holes to achieve a fine adjustment of ±5° between connecting plate 12 and purlin 22.

[0039] In one embodiment of this utility model, the sunshade ventilation hole is a lightning bolt-shaped hole. Preferably, the lightning bolt-shaped hole has a length of 150mm, a maximum hole width of 50mm, a minimum hole width of 10mm, a horizontal spacing of 100mm, a vertical spacing of 80mm, and an opening rate of the folding plate unit 11 greater than 35%, which has a good ventilation and light-blocking effect, and also has a good aesthetic appearance.

[0040] In one embodiment of this utility model, a flange 115 is provided above the folding plate unit 11. The flange 115 is provided on the side of the folding plate unit 11 facing away from the wall and protrudes along the side of the folding plate unit 11. The protruding length of the flange 115 along the light-shielding plate is 2mm, which can effectively improve the sun-shielding effect.

[0041] In one embodiment of this utility model, the maximum distance between the folding plate unit 11 and the wall is not less than 200mm, which can form an air layer between the folding plate unit 11 and the wall, promote air convection, and reduce the diffusion of heat into the factory.

[0042] In one embodiment of this utility model, the sunshade angles of several folding plate units 11 are the same, all not less than 30°. The sunshade angles can be adapted to the summer sun altitude angle (about 60°) to block diffuse reflection light a second time and improve the sunshade effect.

[0043] In one embodiment of this utility model, the sunshade angles of two adjacent folding plate units 11 in a plurality of folding plate units 11 are different, with the smallest sunshade angle not less than 30°. The unit-type sunshade 1 in the sunshade system can be designed as a single layer or multiple layers arranged horizontally along the wall. In one embodiment of this utility model, the unit-type sunshade 1 is designed as multiple layers along the wall, and the sunshade angles of each folding plate unit 11 and its upper, lower, left, and right adjacent folding plate units 11 are different, thus allowing the air layer formed on the wall to have multiple different air inlets, thereby improving the airflow efficiency within the air layer.

[0044] In one embodiment of this utility model, an anti-wear component is provided between the purlin 22 and the connecting plate 12. The anti-wear component can be a 5mm thick rubber pad, which can effectively prevent abnormal noise caused by friction between the purlin 22 and the connecting plate 12.

[0045] In one embodiment of this utility model, the edges of the sunshade ventilation holes are rounded, and the radius of the rounded corners can be set to 2mm, which can effectively avoid stress concentration that could cause the sunshade to crack.

[0046] In one embodiment of this utility model, the sunshade can be made of forged galvanized steel plate and matched with stainless steel bolts. Its weather resistance can reach more than 15 years and the maintenance-free period can reach more than 5 years, which effectively reduces the maintenance cost of the sunshade system.

[0047] Finally, it should be noted that the above description represents the preferred embodiment of this utility model. It should be pointed out that although the preferred embodiment of this utility model has been described, those skilled in the art, once they understand the basic inventive concept of this utility model, can make several improvements and modifications without departing from the principles described herein. These improvements and modifications should also be considered within the protection scope of this utility model. Therefore, the appended claims are intended to be interpreted as including the preferred embodiment as well as all changes and modifications falling within the scope of the embodiments of this utility model.
