Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, and specifically to a wind-resistant and airflow-guiding structure for buildings. Background Technology

[0002] Coastal areas are frequently hit by typhoons, and the extreme winds pose a threat to high-rise buildings, long-span bridges, and other tall structures. In recent years, accidents caused by strong winds vibrating and damaging building roofs and bridges have occurred frequently. Therefore, improving the wind resistance of building structures is a key research topic in the field of engineering. When strong winds pass over non-streamlined roofs (such as parapet walls and bridge cross-sections), they usually generate periodic shedding vortices behind the structure. When the shedding frequency of the vortices approaches the natural frequency of the structure, a resonance effect occurs, leading to structural wind resistance failure. Currently, structural wind resistance mainly employs aerodynamic optimization (such as designing the building edges to facilitate airflow) and active optimization measures (such as opening holes at the structural edges or installing dampers) to suppress vortex formation and ensure structural stability and safety. However, aerodynamic optimization measures are only suitable for new buildings. Applying aerodynamic optimization to existing buildings can damage the original building structure and even change its function. Active optimization measures are difficult to implement and have high maintenance costs.

[0003] Therefore, a wind-resistant structure that is simple in structure and easy to install is needed to improve the wind resistance performance of buildings. Utility Model Content

[0004] One of the objectives of this utility model is to provide a wind-resistant and airflow-guiding structure for buildings, so as to solve the problem that existing buildings are difficult to wind-resistant and airflow-guiding in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wind-resistant airflow guiding structure for building wind resistance includes: multiple wind-resistant airflow guiding units and a first connector. Each wind-resistant airflow guiding unit is installed on the edge of the building, and two adjacent wind-resistant airflow guiding units are hinged together by the first connector. Each wind-resistant airflow guiding unit includes a strip-shaped shell and multiple arc-shaped airflow guiding pipes. The strip-shaped shell is installed on the edge of the building. A sealed cavity is formed inside the strip-shaped shell, and each arc-shaped airflow guiding pipe is installed in the sealed cavity and its two ends are connected to the outside. The two ends of each arc-shaped airflow guiding pipe are respectively located on two different sides of the strip-shaped shell.

[0006] Based on the aforementioned technical means, the arc-shaped guide pipe allows airflow to flow in from one end and out from the other, changing the direction of airflow and guiding it. This allows the airflow to flow through the building via a specific path, preventing the formation of airflow vortices at the building's edges and improving the building's wind resistance. The strip shell and the arc-shaped guide pipe together form a modular installation structure, and adjacent strip shells can be connected by a first connector, making the installation of the wind-resistant guide structure simple, fast, and efficient.

[0007] Meanwhile, the wind-resistant guiding unit of this utility model has a simple structure, is easy and efficient to install, has low production cost, and can flexibly select the number of wind-resistant guiding units according to the building size, making it highly adaptable.

[0008] Furthermore, the strip-shaped shell has a windward surface and an air outlet surface, which are located on different planes; the two ends of the arc-shaped guide pipe are located on the windward surface and the air outlet surface, respectively, and are connected to the outside.

[0009] Based on the aforementioned technical means, the windward and exhaust surfaces located on different planes allow the airflow to change its direction and speed through a specific path of the arc-shaped guide tube after impacting the windward surface, and then flow out from the exhaust surface. This can weaken the pressure of the airflow directly acting on the building, reduce the impact force of the airflow on the building, and enhance the building's wind resistance stability.

[0010] Furthermore, the plurality of the arc-shaped guide tubes are evenly spaced along the length of the strip-shaped shell.

[0011] Based on the above-mentioned technical means, the evenly spaced arc-shaped guide pipes can guide the airflow uniformly and stably, thereby weakening the impact force of the airflow, reducing airflow turbulence, and improving the safety of buildings in strong airflow environments.

[0012] Furthermore, an arc-shaped airflow guiding surface is formed on the strip-shaped shell, and the two opposite sides of the arc-shaped airflow guiding surface are respectively connected to the windward surface and the air outlet surface for guiding air.

[0013] Based on the above technical means, when airflow impacts the windward surface, the arc-shaped guide surface can guide the airflow that has not passed through the arc-shaped guide pipe, so that the airflow flows smoothly through the building and prevents the airflow from concentrating and forming vortices.

[0014] Furthermore, the first connecting member includes a connecting plate, a first hinge member, and a second hinge member, wherein the first hinge member and the second hinge member are used to hinge the opposite sides of the connecting plate to two adjacent wind-resistant guide units respectively.

[0015] According to the above technical means, the connecting plate, the first hinge and the second hinge enable the two adjacent wind-resistant guiding units to rotate within the plane of the connecting plate when impacted by airflow, so as to consume part of the airflow impact and building vibration energy, avoid damage to the wind-resistant guiding units under airflow impact, and improve the service life of the wind-resistant guiding units.

[0016] Furthermore, the first hinge includes a first nut, a second nut, and a first screw. The first nut is embedded in one end of the strip-shaped housing. One end of the first screw passes through the connecting plate and the strip-shaped housing and is locked to the first nut. The other end of the first screw is locked to the second nut.

[0017] Furthermore, the second hinge includes a third nut, a fourth nut, and a second screw. The third nut is embedded in one end of the strip-shaped housing of the adjacent wind-resistant and flow-guiding unit. One end of the second screw passes through the connecting plate and the strip-shaped housing of the adjacent wind-resistant and flow-guiding unit and is locked to the third nut. The other end of the second screw is locked to the fourth nut.

[0018] Based on the above technical means, the connection method of nuts and screws is simple, fast and reliable, and easy to assemble and disassemble; it improves the efficiency of connecting / disassembling two adjacent wind-resistant and airflow-guiding units.

[0019] Furthermore, the connecting plate is a steel plate.

[0020] Based on the above technical means, the steel plate has high strength and rigidity, can withstand high loads, and can effectively prevent its own deformation, resulting in a long service life.

[0021] Furthermore, each of the wind-resistant and flow-guiding units also includes a second connector, which is installed on the strip-shaped shell and arranged along the length of the strip-shaped shell for connecting to the existing building.

[0022] Based on the aforementioned technical means, the second connector provides an installation base for the strip shell to be installed on the existing building, so that construction personnel can quickly connect the strip shell to the existing building.

[0023] Furthermore, the second connecting member is a strip-shaped rod, which is arranged along the length direction of the strip-shaped shell.

[0024] The above-mentioned technical means enable the strip shell to be linearly connected to the existing building, thereby improving the reliability of the wind-resistant diversion unit installed on the existing building.

[0025] The beneficial effects of this utility model are as follows: 1. The arc-shaped guide tube allows airflow to flow in from one end and out from the other, changing the direction of the airflow and guiding it. This allows the airflow to flow through the building along a specific path, preventing the formation of airflow vortices at the building's edges and improving the building's wind resistance. The strip shell and the arc-shaped guide tube together form a modular installation structure, and adjacent strip shells can be connected by a first connector, making the installation of the wind-resistant guide structure simple, fast, and efficient.

[0026] 2. The wind-resistant guiding unit of this utility model has a simple structure, is easy and efficient to install, has low production cost, and can flexibly select the number of wind-resistant guiding units according to the building size, making it highly adaptable.

[0030] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. The drawings are for illustrative purposes only and should not be construed as limiting the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] This embodiment provides, as follows: Figures 1 to 6 The diagram illustrates a wind-resistant airflow guiding structure for building wind resistance, comprising: multiple wind-resistant airflow guiding units 100 and a first connector 200. Each wind-resistant airflow guiding unit 100 is installed on the edge of the building, and adjacent wind-resistant airflow guiding units 100 are hinged together by the first connector 200. Each wind-resistant airflow guiding unit 100 includes a strip-shaped shell 110 and multiple arc-shaped airflow guiding pipes 120. The strip-shaped shell 110 is installed on the edge of the building. A sealed cavity is formed inside the strip-shaped shell 110, and each arc-shaped airflow guiding pipe 120 is installed inside the sealed cavity, with both ends connected to the outside. The two ends of each arc-shaped airflow guiding pipe 120 are located on two different sides of the strip-shaped shell 110.

[0033] When the wind-resistant guiding structure of this embodiment is installed on an existing building, multiple wind-resistant guiding units 100 are connected to the existing building, and adjacent wind-resistant guiding units 100 are connected using the first connector 200. In a strong wind environment, the airflow impacting the building can be guided by the arc-shaped guiding pipe 120, thereby preventing the airflow from directly impacting the building or forming vortices at the building's edge.

[0034] The arc-shaped guide pipe 120 allows airflow to flow in from one end and out from the other, changing the direction of the airflow and guiding it. This allows the airflow to flow through the building via a specific path, preventing the formation of airflow vortices at the building's edges and improving the building's wind resistance. The strip shell 110 and the arc-shaped guide pipe 120 together form a modular installation structure, and adjacent strip shells 110 can be connected by the first connector 200, making the installation of the wind-resistant guide structure simple, fast, and efficient.

[0035] Meanwhile, the wind-resistant guiding unit 100 in this embodiment has a simple structure, is easy and efficient to install, has low production cost, and can flexibly select the number of wind-resistant guiding units 100 according to the building size, making it highly adaptable.

[0036] like Figure 1 As shown, in this embodiment, the strip-shaped shell 110 has a windward surface 111 and an air outlet surface 112, which are located on different planes. The two ends of the arc-shaped guide pipe 120 are located on the windward surface 111 and the air outlet surface 112, respectively, and are connected to the outside environment. Specifically, the windward surface 111 and the air outlet surface 112 are perpendicular to each other. The windward surface 111 and the air outlet surface 112, located on different planes, allow the airflow to change its direction and speed through a specific path of the arc-shaped guide pipe 120 after impacting the windward surface 111, and then flow out from the air outlet surface 112. This weakens the pressure of the airflow directly acting on the building, reduces the impact force of the airflow on the building, and enhances the building's wind resistance stability. The arc-shaped guide pipe 120 has an air inlet 121 and an air outlet 122, with the air inlet 121 located on the windward surface 111 and the air outlet 122 located on the air outlet surface 112.

[0037] In this embodiment, the cross-section of the strip-shaped shell 110 is as follows: Figure 4 As shown, this is a shape formed by cutting a parallelogram.

[0038] like Figure 1 As shown, in this embodiment, multiple arc-shaped guide pipes 120 are evenly spaced along the length of the strip-shaped shell 110. The evenly spaced arc-shaped guide pipes 120 can guide the airflow uniformly and stably, uniformly weakening the impact force of the airflow, reducing airflow turbulence, and improving the safety of the building in strong airflow environments. Specifically, as... Figure 5 As shown, when the airflow impacts the windward surface 111 of the strip-shaped shell 110, some of the airflow can flow through the arc-shaped guide tube 120. At this time, since the multiple arc-shaped guide tubes 120 are evenly distributed inside the strip-shaped shell 110, the airflow can form an air wall when it flows out through the air outlet surface 112 (due to the narrow tube effect of the arc-shaped guide tube 120, the airflow velocity from the arc-shaped guide tube 120 increases, and the velocity reaches its maximum at the outlet of the arc-shaped guide tube 120, so that a solid air wall can be formed at the air outlet surface 112). This not only suppresses the vortex generated by the airflow itself, but also prevents other airflows from developing into vortices through the air wall.

[0039] It is worth noting that the interior of the arc-shaped guide tube 120 is smooth and without sharp edges.

[0040] like Figure 4 and Figure 5As shown, in this embodiment, an arc-shaped guide surface 113 is also formed on the strip-shaped shell 110. The two opposite sides of the arc-shaped guide surface 113 are connected to the windward surface 111 and the air outlet surface 112, respectively, for guiding airflow. When the airflow impacts the windward surface 111, the arc-shaped guide surface 113 can guide the airflow that has not passed through the arc-shaped guide pipe 120, allowing the airflow to flow smoothly through the building and preventing the airflow from concentrating and forming vortices. Specifically, some of the gas that has not flowed through the arc-shaped guide pipe 120 can "climb" through the arc-shaped guide surface 113 to flow through the strip-shaped shell 110, avoiding the formation of vortices at the strip-shaped shell 110.

[0041] like Figure 6 As shown, in this embodiment, the first connecting member 200 includes a connecting plate 210, a first hinge 220, and a second hinge 230. The first hinge 220 and the second hinge 230 are used to hinge the opposite sides of the connecting plate 210 to two adjacent wind-resistant guiding units 100. The connecting plate 210, the first hinge 220, and the second hinge 230 enable the two adjacent wind-resistant guiding units 100 to rotate within the plane of the connecting plate 210 when impacted by airflow. Specifically, as shown... Figure 3 As shown, when connecting two adjacent strip shells 110, there is a gap between the two strip shells 110 so that the two adjacent strip shells 110 can rotate to a certain extent, so as to consume some of the airflow impact and building vibration energy, avoid damage to the wind-resistant guide unit 100 under airflow impact, and improve the service life of the wind-resistant guide unit 100.

[0042] like Figure 6 As shown, in this embodiment, the first hinge 220 includes a first nut 221, a second nut 222 and a first screw 223. The first nut 221 is embedded in one end of the strip housing 110. One end of the first screw 223 passes through the connecting plate 210 and the strip housing 110 and is locked to the first nut 221. The other end of the first screw 223 is locked to the second nut 222.

[0043] like Figure 6 As shown, in this embodiment, the second hinge 230 includes a third nut 231, a fourth nut 232, and a second screw 233. The third nut 231 is embedded in one end of the strip-shaped housing 110 of the adjacent wind-resistant guiding unit 100. One end of the second screw 233 passes through the connecting plate 210 and the strip-shaped housing 110 of the adjacent wind-resistant guiding unit 100 and is locked to the third nut 231. The other end of the second screw 233 is locked to the fourth nut 232. The connection method of the nut and screw is simple, fast, reliable, and convenient to assemble and disassemble, thus improving the efficiency of connecting / disassembling two adjacent wind-resistant guiding units 100.

[0044] During use, the first nut 221 and the second nut 222, and the third nut 231 and the fourth nut 232 do not firmly lock the connecting plate 210 and the strip shell 110 onto the first screw 223 and the second screw 233, but leave a certain amount of rotation space so that the two adjacent strip shells 110 can rotate and displace to absorb energy when the building vibrates under strong winds during use, thus preventing damage to the overall structure.

[0045] To prevent the second nut 222 from falling off the first screw 223 due to positional shift caused by vibration during use, a pin hole can be provided along the diameter of one end of the screw extending out of the strip housing 110, and a pin can be inserted into the pin hole to prevent it from falling off; of course, the fourth nut 232 can also be designed in the same way to prevent it from falling off.

[0046] In this embodiment, the connecting plate 210 is a steel plate. Steel plates have high strength and rigidity, can withstand high loads while effectively preventing deformation, and have a long service life.

[0047] like Figure 2 As shown, in this embodiment, each wind-resistant guiding unit 100 further includes a second connector 130. The second connector 130 is installed on the strip-shaped shell 110 and is arranged along the length of the strip-shaped shell 110 for connecting to the existing building. The second connector 130 provides an installation base for the strip-shaped shell 110 to be installed on the existing building, so that construction personnel can quickly connect the strip-shaped shell 110 to the existing building. During connection, the second connector 130 can be connected to the existing building by welding or screwing. Specifically, the wind-resistant guiding structure of this embodiment is usually set at the edge of the building, such as the parapet wall of a building, the lower edge of the sloping roof, and the bridge deck. These locations are usually the separation points of airflow and the key parts for the formation of vortices. Therefore, the wind reduction effect is best when the wind-resistant guiding structure is set at these locations. Among them, the second connector 130 is usually connected to the lightning protection strip at the parapet wall of the building and the guardrail of the bridge deck to form an auxiliary object.

[0048] In other embodiments, holes can be drilled in the second connector 130, and then the second connector 130 can be bound to the existing building (such as the lightning protection strip at the parapet wall or the guardrail on the bridge deck) by means of a buckle, steel rope, etc.

[0049] like Figure 2As shown, in this embodiment, the second connecting member 130 is a strip-shaped rod, which is arranged along the length of the strip-shaped shell 110. This enables the strip-shaped shell 110 to be linearly connected to the existing building, improving the reliability of the wind-resistant guide unit 100 installed on the existing building. Of course, multiple strip-shaped rods can be installed on the strip-shaped shell 110 to connect to the existing building, increasing the stability of the strip-shaped shell 110 connected to the existing building through multiple linear connections.

[0050] To enhance the structural strength and stability of the wind-resistant guide unit 100, fillers (such as expanded clay, foamed cement, concrete, etc.) can be used inside the strip shell 110 to increase its structural stability by adding weight.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
