[0006] To ensure the relative closure of the construction site, most enclosures currently adopt closed or shutter designs. However, due to the influence of the typhoon season in coastal areas, the enclosure has a low air permeability, which increases the possibility of overall overturning, wall tearing, and node damage of the enclosure. The large wind-exposed area becomes one of the main reasons for the damage of the enclosure. Therefore, it is necessary to provide a wind-resistant construction enclosure baffle with good anti-see-through performance to ensure the relative closure of the temporary enclosure.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Figure 1 This is a schematic diagram of the structure of a fiber-reinforced polyurethane composite material ventilation baffle for construction enclosures of the utility model; Figure 2 It is a schematic diagram of the structure of the transverse baffle on the fiber-reinforced polyurethane composite material ventilation baffle used for construction enclosures of the utility model.

[0023] See also Figure 1 and Figure 2The utility model provides a fiber reinforced polyurethane composite material ventilation baffle for construction fencing, comprising a baffle body 1, wherein the baffle body 1 is provided with a plurality of parallel transverse baffle bars 2, the transverse baffle bars 2 are provided with through holes 3 penetrating from top to bottom, a groove is formed between two adjacent transverse baffle bars 2 and a vertical rib 4 is provided; the baffle body 1, the vertical rib 4, the transverse baffle bar 2 and the through holes 3 thereon are integrally formed, and the material is fiber reinforced polyurethane; the upper and lower parts of the baffle body 1 are provided with baffle limiting channel steels 5.

[0024] The baffle body 1 of the utility model is in the shape of a Chinese character "bow". A through hole 3 is arranged in the transverse section of the Chinese character "bow" to play the role of ventilation and water permeability. A vertical rib 4 is arranged at the midpoint of the vertical section of the leeward side to enhance the bending resistance of the baffle. The enclosure baffle improves the overall air permeability and the overall wind resistance of the baffle by arranging ventilation holes and adding vertical ribs at the midpoint of the concave section on the leeward side of the enclosure baffle. The elliptical through hole of the baffle is arranged in the transverse section to be visually invisible, and does not affect the project publicity effect on the outer surface of the fence. The enclosure baffle of the utility model can separate the construction area from the external environment, effectively block the sight of the outside world, protect the safety and privacy of items on the construction site, and ensure the safety of external personnel and the construction site. It has both anti-see-through and ventilation functions, and the enclosure baffle is flat, which is conducive to project publicity.

[0025] The utility model increases the overall air permeability by opening holes in the transverse section of the enclosure baffle, and the wind is divided into two holes at the upper and lower sides when approaching the baffle. Figure 3 As shown in the figure, the Karman vortex street phenomenon is alleviated to a certain extent. Increasing the air permeability means reducing the blocking effect of obstacles on the fluid, which may reduce the intensity and frequency of the vortex, and the impact of the vortex on the structure will be reduced, thereby alleviating problems such as vibration or noise caused by the Karman vortex street.

[0026] The upper and lower parts of the baffle body 1 of the utility model are both provided with baffle limiting channel steels 5, and the enclosure baffle is clamped in the channel steel. If there is a size mismatch, a rubber strip can be added to ensure that the enclosure and the channel steel do not shake. In the utility model, no connecting components are required between the baffles of the enclosure. If necessary, holes can be opened on the side and connected with bolts. The limiting channel steel 5 is inserted into the hole reserved for the column 6. The height of the hole reserved for the column 6 should be slightly higher than the height of the enclosure baffle. After the enclosure baffle is installed, a rubber pad is placed on the upper part of the limiting channel steel 5 to fix the column, the limiting channel steel and the baffle. Figure 4 The utility model abandons the traditional method of connecting the baffle plate by screws, and designs the connection between the enclosure and the column as a "mortise and tenon" connection, which reduces the loss of parts and reduces the possibility of tearing of the enclosure baffle plate due to the screw connection.

[0027] The enclosure baffle of the utility model is made of fiber-reinforced polyurethane composite material (with triaxial cloth, anisotropic material), wherein the longitudinal bending strength of the 2mm thick polyurethane composite material can reach 890MPa (the bending strength of 2mm steel is between 360-510MPa), and it has the characteristics of high strength and high elasticity; the preferred thickness is 2mm-5mm, which can effectively improve the rigidity and stability of the enclosure. At the same time, the fiber-reinforced polyurethane composite material also has good weather resistance and corrosion resistance, can adapt to various harsh environmental conditions, and improve the service life of the enclosure baffle. The fiber-reinforced polyurethane composite material has good toughness, can absorb the vibration and deformation of the baffle caused by wind, increase the elasticity and impact resistance of the enclosure, and reduce the destructive effect of wind on the enclosure.

[0028] In summary, the fiber-reinforced polyurethane composite material ventilation baffle for construction enclosure provided by the utility model has the following advantages:

[0029] 1. Modular enclosure baffles are highly standardized and can be recycled

[0030] Modular polyurethane wind-resistant enclosures are a recyclable building structure with high economic benefits. This construction method has the advantages of short construction period, low labor cost, less material waste, etc., which can significantly reduce construction costs. In addition, due to the simple structure and high degree of standardization of modular fences, their maintenance is relatively easy, which can extend their service life and can be recycled.

[0031] 2. This enclosure baffle increases the overall air permeability by opening holes in the transverse section. When the wind approaches the baffle, it is diverted by the upper and lower holes, which to a certain extent reduces the Karman vortex street phenomenon and improves the bearing capacity of the enclosure.

[0032] 3. The elliptical through holes of the enclosure baffle are arranged in the transverse section to be visually invisible, without affecting the project publicity effect on the outer surface of the fence. It has both anti-see-through and ventilation functions, and the enclosure baffle is flat, which is conducive to project publicity.

[0033] 4. The enclosure baffles are made of fiber-reinforced polyurethane composite materials, which have good weather resistance and corrosion resistance, can adapt to various harsh environmental conditions, and improve the service life of the enclosure baffles. They also have good toughness, can absorb the vibration and deformation of the baffles caused by wind, increase the elasticity and impact resistance of the enclosure, and reduce the destructive effects of wind on the enclosure.

Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
