Awnings

Abstract

The present application belongs to the field of building structure, and relates to a canopy. The roof in the present application comprises a flow guide support pipe, a mounting frame and a flow guide cover plate. The flow guide support pipe is provided with a plurality of flow guide support pipes and is fixedly installed on the top of the support frame. The plurality of flow guide support pipes are parallel to each other and are arranged in an interval along the left-right direction. The left side wall and the right side wall of the flow guide support pipe are oppositely arranged inclined outer side walls. The flow guide groove bodies are fixedly arranged on the two inclined outer side walls respectively. The rear side of the mounting frame is hingedly connected with the rear side of the top end of the support frame. The plurality of flow guide cover plates are fixedly arranged on the mounting frame. One flow guide support pipe is arranged between every two adjacent flow guide cover plates. In the case of strong wind and rain, the flow guide cover plate is rotated to form a wind gap between the lower surface of the flow guide cover plate and the groove top wall of the flow guide groove body. The wind gap can disperse the wind flow, reduce the wind resistance and weaken the impact of the strong wind on the roof. The inclined outer side wall can effectively block the rainwater to prevent the rainwater from penetrating through the wind gap.

Description

Technical Field

[0001] This invention belongs to the field of building structures, and more specifically relates to a canopy. Background Technology

[0002] Awnings are architectural fixtures used to block rain, wind, and falling objects. Existing awnings mainly consist of a steel support frame and sheet material covering and fixing it, such as tempered glass, membrane material, metal plate, or fiberglass. These awnings can block rain and falling objects, and also have a certain degree of wind resistance. However, due to climate change, frequent extreme weather events, and high wind speeds, the wind resistance of existing awnings has certain problems, increasing the probability of them being blown over. To improve the wind resistance of awnings, there are two common approaches: one is to reinforce the support frame, and the other is to add ventilation holes to the awning. The first approach is costly, has a large overall structural weight, and cannot be effectively reinforced in some situations. The second approach, while able to disperse airflow and reduce wind resistance, reduces the awning's rain-blocking effect. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a canopy with a simple and reliable structure and good wind resistance and rain protection.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a canopy, including a support frame and a roof, the roof including a flow guide pipe, a mounting frame, and a flow guide cover plate. Multiple flow guide pipes are provided and fixedly installed on the top of the support frame. The multiple flow guide pipes are parallel to each other and spaced apart in the left-right direction. The center lines of the multiple flow guide pipes together define a reference plane I that is inclined relative to the horizontal plane in the front-back direction, with the front end of the reference plane I lower than the rear end. The left and right sides of the flow guide pipes are oppositely arranged oblique outer walls, and the lateral distance between the top ends of the left and right sides of the flow guide pipes is smaller than the lateral distance between the bottom ends. A flow guide channel with a top opening is fixedly provided on the left and right outer walls of the flow guide pipes, the extension direction of the flow guide channel is the same as the length direction of the flow guide pipe, and the front end of the flow guide channel is an open structure. The rear side of the mounting frame is hinged to the rear side of the top of the support frame, and there is a gap between them. A hinge axis is horizontally arranged and extends along the left-right direction. Multiple flow guide covers are provided and fixed on the mounting frame. The length direction of the flow guide covers and the length direction of the flow guide tubes are perpendicular to the hinge axis. Multiple flow guide covers are arranged sequentially at intervals along the length direction of the hinge axis. The center lines of the multiple flow guide covers in the length direction jointly define a reference plane. A flow guide tube is arranged between each pair of adjacent flow guide covers. In the natural state, the left and right sides of the lower surface of the flow guide cover overlap the top of the flow guide channel, and the left and right edges of the flow guide cover are in contact with the corresponding oblique outer wall or have a preset distance. The mounting frame is equipped with a travel limiter to control the upward rotation of the front side of the mounting frame relative to the front side of the support frame. When the external force that causes the front side of the mounting frame to rotate upward relative to the front side of the support frame disappears, the mounting frame and the flow guide covers can return to their natural state by their own weight.

[0005] As can be seen from the above technical solution, compared with the prior art, the canopy of the present invention includes a flow guide pipe fixed relative to the support column and a flow guide cover plate that can rotate around the hinge axis. In the absence of wind or weak wind, the flow guide cover plate is in a natural state. Under its own gravity, the left and right sides of the lower surface of the flow guide cover plate respectively overlap the top of the flow guide channel. Most of the rainwater will flow obliquely downwards towards the ground through the upper surface of the flow guide cover plate. A small amount of rainwater may pass through the long side and the oblique outer wall of the flow guide cover plate and flow into the flow guide channel. The rainwater in the flow guide channel can also flow obliquely downwards towards the ground, thus ensuring the rain-blocking effect. In the case of strong wind, the wind will blow the front side of the flow guide cover plate to rotate upwards around the hinge axis. At this time, a ventilation gap will be formed between the lower surface of the guide cover and the top wall of the guide channel, or the ventilation gap will gradually increase. This ventilation gap can effectively disperse the airflow, reduce wind resistance, weaken the impact of strong winds on the roof, and prevent the entire roof from being blown over by the wind. The stroke limiter can control the rotation of the guide cover within a safe stroke range. When the wind decreases, the guide cover and the mounting frame can return to their original positions under their own gravity. If it is accompanied by rain, even if the wind blows the rainwater and it falls at an angle, the outer wall of the slope will effectively block the rainwater and prevent the rainwater from passing through the ventilation gap. The rainwater splashed on the outer wall of the slope will flow into the guide channel. Even if strong winds and rain occur at the same time, the roof can not only provide rain protection, but also effectively disperse the airflow and prevent it from being blown over by the wind.

[0006] To ensure a simple and reliable structure, easier processing and assembly, and better overall rainwater drainage, in the preferred scheme, under natural conditions, reference plane one and reference plane two are parallel or coplanar.

[0007] To ensure a simple and reliable structure, and to facilitate processing and assembly, in the preferred embodiment, the mounting frame is a rectangular frame composed of transverse and longitudinal beams. The guide cover is fixedly installed within the inner ring area enclosed by the rectangular frame. The center lines along the length directions of the transverse and longitudinal beams together define a reference plane three, which is parallel to or coplanar with reference plane two. The front end face of the guide channel and the front end face of the guide support pipe are flush, as are the rear end face of the guide channel and the rear end face of the guide support pipe. Preset distances exist between the front end face of the guide support pipe and the inner ring end wall of the rectangular frame, and between the rear end face of the guide support pipe and the inner ring end wall of the rectangular frame. These preset distances are determined based on the rotation space required for the mounting frame to rotate around the hinge axis and the required space dimensions for the drainage channel in this area. This design effectively ensures the reliability of the overall rotating structure of the guide cover and mounting frame, while also facilitating smooth rainwater drainage.

[0008] To ensure a simple and reliable structure that is easier to process and assemble, in the preferred embodiment, multiple flow guide tubes are arranged at uniform intervals, and multiple flow guide covers are arranged at uniform intervals.

[0009] To effectively ensure rain protection, in the preferred embodiment, the travel limiter allows the front end of the guide cover to be limited to the area below the plane of the top edge of the oblique outer wall of the guide support tube. This travel limit design helps to ensure the rain protection effect of the guide cover at the extreme position, that is, to ensure that in rainy weather and strong winds, the obliquely falling rainwater will not pass through the gap between adjacent guide support tubes.

[0010] In a preferred embodiment, the support frame includes support columns, mounting brackets, struts, and positioning bolts. The axis of the support columns is arranged vertically, and at least two support columns are provided, spaced apart in the left-right direction. The rear end of the mounting bracket is hinged to the upper end of the support column, and there is a second hinge axis between them. The second hinge axis is parallel to the first hinge axis. Multiple guide tubes are fixed on the mounting bracket. At least two struts are provided, one end of which is hinged to the middle of the mounting bracket, and there is a third hinge axis between them. The other end of the strut is provided with a insertion hole. The center line of the third hinge axis and the center line of the insertion hole are both parallel to the second hinge axis. Multiple positioning holes are provided on the support column, spaced apart along its axis. The center line of the positioning hole is parallel to the second hinge axis. The insertion hole can be directly opposite any of the positioning holes. Positioning bolts are inserted into the insertion hole and a positioning hole directly opposite the insertion hole to connect the strut and the support column. This design allows for adjustment of the angle between the reference plane and the horizontal plane. Positioning holes at appropriate heights are selected based on actual conditions and matched with insertion holes using positioning bolts. This design improves the canopy's wind resistance and ensures that rainwater in the drainage channel and on the drainage cover can flow quickly and smoothly to the ground.

[0011] To make the structure simple and reliable, and easier to process and assemble, in the preferred embodiment, the travel limit component is a limit rope, with one end of the limit rope fixedly connected to the front end of the mounting frame and the other end fixedly connected to the front end of the mounting bracket.

[0012] In a preferred embodiment, multiple through holes are provided on the sloping outer wall of the guide tube. These through holes are spaced apart along the length of the guide tube. The inner side of the guide channel is connected to the inner cavity of the guide tube through these through holes, and the front end of the guide tube is open. When there is excessive rainwater in the guide channel, the rainwater can flow into the guide tube and drain from the front end of the guide tube, thus preventing rainwater from overflowing from the top wall of the guide channel and affecting its rain-blocking effect.

[0013] In a preferred embodiment, the cross-section of the upper surface of the guide cover is V-shaped, which allows the guide cover to more effectively block rain and guide rainwater down to the ground.

[0014] In a preferred embodiment, the lower surface of the flow guide cover is integrally formed with multiple strip-shaped protrusions (first and second). The extension direction of the first strip-shaped protrusion is consistent with the length direction of the flow guide cover, while the extension direction of the second strip-shaped protrusion is perpendicular to the length direction of the flow guide cover. The first and second strip-shaped protrusions act as reinforcing ribs, improving the structural strength of the flow guide cover and making it less prone to deformation when blown by wind.

Detailed Implementation

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 9This invention discloses a canopy, including a support frame and a canopy. The canopy includes a flow guide pipe 2, a mounting frame 3, and a flow guide cover plate 4. Multiple flow guide pipes 2 are provided and fixedly installed on the top of the support frame. The multiple flow guide pipes 2 are parallel to each other and spaced apart in the left-right direction. The center lines of the multiple flow guide pipes 2 together define a reference plane 1 that is inclined relative to the horizontal plane in the front-back direction. The front end of the reference plane 1 is lower than the rear end. The left and right sides of the flow guide pipes 2 are oppositely arranged oblique outer walls 20. The lateral distance between the top ends of the left and right sides of the flow guide pipes 2 is smaller than the lateral distance between the bottom ends (for the same flow guide pipe 2, this is equivalent to two oblique outer walls 20). 0 (extending at an angle towards each other from bottom to top); the left and right outer walls of the guide tube 2 are respectively fixed with guide channels 21 with top openings. To simplify the device structure, in a preferred embodiment, the outer wall of the guide tube 2 can be directly used as the channel wall of the guide channel 21 on the side close to the guide tube 2. The extension direction of the guide channel 21 is the same as the length direction of the guide tube 2 (that is, the axis of the guide channel 21 is inclined in the front-to-back direction, and the front end is lower than the rear end). The front end of the guide channel 21 is an open structure, mainly used for rainwater drainage in the guide channel 21. There is no mandatory requirement for the rear end of the guide channel 21. The structure can be either closed or open; the rear side of the mounting frame 3 is hinged to the rear top of the support frame, and there is a horizontally arranged hinge axis extending in the left-right direction between them, which means that the entire mounting frame 3 can rotate around the hinge axis; multiple flow guide plates 4 are provided and fixed on the mounting frame 3. The length direction of the flow guide plate 4 and the length direction of the flow guide tube 2 are both perpendicular to the hinge axis. Multiple flow guide plates 4 are arranged sequentially at intervals along the length direction of the hinge axis. The center lines of the multiple flow guide plates 4 in the length direction together define a reference plane 2. The "center line in the length direction of the flow guide plate 4" refers to the geometric center of its cross-section perpendicular to its length direction. The connection is as follows: A guide pipe 2 is arranged between each pair of adjacent guide covers 4 (that is, the guide covers 4 and the guide pipes 2 are arranged alternately in the left and right directions). In the natural state, the lower surface of the guide cover 4 is respectively connected to the top of the guide channel 21 on the left and right sides (it can be directly connected to the top of the channel wall of the guide channel 21, or it can be connected to the oblique outer wall 20, or it can be connected to the oblique outer wall 20. This position also corresponds to the limit position of the downward rotation stroke of the mounting frame 3). The left and right edges of the guide cover 4 are in contact with the corresponding oblique outer wall 20 or have a preset distance (the specific distance can be determined according to the rainproof effect and wind resistance performance).The mounting frame 3 is equipped with a travel limiter 8 that controls the upward rotation of the front side of the mounting frame 3 relative to the front side of the support frame. When the external force causing the front side of the mounting frame 3 to rotate upward relative to the front side of the support frame disappears, the mounting frame 3 and the guide cover 4 can return to their natural state under their own weight.

[0029] It is understood that the directional limitations such as front, back, left, and right in this invention are only for the purpose of facilitating understanding of the technical solution. The support frame can be implemented in various ways depending on the application scenario, as long as it can meet the overall support strength of the canopy and provide a basic structure at the top for the installation of the guide pipe 2 and the mounting frame 3.

[0030] The support frame in this invention can be independently and vertically fixed to the ground, meaning the canopy is an independent canopy, not attached to a building; or it can be fixed to the outer wall of a building, see reference. Figure 10 In this embodiment, the support frame is fixed to the outer wall of the building. When the support frame is fixed to the outer wall of the building, after the ceiling and support frame are installed, a water guide channel 9 is usually installed. The water guide channel 9 is located above the rear area of ​​the mounting frame 3. The length of the water guide channel 9 is inclined relative to the horizontal plane in the left-right direction. The hinge position between the mounting frame 3 and the support frame is located between the two side walls of the water guide channel 9. One side wall of the water guide channel 9 is close to the outer side of the building. This design can prevent rainwater from flowing down from the gap between the building and the mounting frame 3. Rainwater falling on the outer wall of the building will flow into the water guide channel 9 and flow to the ceiling side. The width and installation height of the water guide channel 9 are appropriate to ensure that the guide cover 4 will not interfere with the water guide channel 9 when rotating upward around the hinge axis. In some alternative embodiments, the water guide channel 9 can also drain water from other locations, such as guiding water to the upper surface of the ceiling for drainage, or draining water from both sides simultaneously, etc. When the support frame is fixed to the entrance and exit area on the outer wall of the building, the support frame can usually adopt a portal frame structure, which includes support columns 1 on both sides of the entrance and exit, and a crossbeam above the entrance and exit. The axis of the support column 1 is set vertically, and the crossbeam is fixedly connected to the support column 1. The top area of ​​the crossbeam and the support column 1 is then equipped with an installation frame 5 for arranging the flow guide pipe 2.

[0031] The canopy in this invention includes a flow guide pipe 2 fixed relative to the support frame and a flow guide cover 4 rotatable about a hinge axis. In the absence of wind or with weak wind, the lower surface of the flow guide cover 4 overlaps the top of the flow guide channel 21 on its left and right sides respectively. The oblique outer wall 20 is in close contact with the long side of the flow guide cover 4 or has a small gap. If it rains, most of the rainwater will flow obliquely downwards to the ground through the upper surface of the flow guide cover 4. A small portion of the rainwater may pass between the long side of the flow guide cover 4 and the oblique outer wall 20 and flow into the flow guide channel 21. The rainwater in the flow guide channel 21 can also flow obliquely downwards to the ground, thus ensuring a rain-blocking effect. In strong wind conditions, the wind will blow... The movable guide cover 4 rotates upward around the hinge axis. At this time, a ventilation gap is formed or enlarged between the lower surface of the guide cover 4 and the top wall of the guide channel 21. The ventilation gap is wedge-shaped, which can disperse the airflow, reduce wind resistance, weaken the impact of strong wind on the roof, and prevent the entire roof from being blown over by the wind. If it is accompanied by rain, even if the wind blows the rainwater and it falls at an angle, the outer wall 20 will effectively block the rainwater and prevent the rainwater from passing through the ventilation gap. The rainwater splashed on the outer wall 20 will flow into the guide channel 21. Even if strong wind and rain occur at the same time, the roof can not only provide rain protection, but also effectively disperse the airflow and prevent it from being blown over by the wind. The flow guide plate 4 is reliably fixed in the mounting frame 3, and the flow guide plate 4 and the mounting frame 3 as a whole can reliably rotate around the hinge axis; the stroke limiter 8 can control the flow guide plate 4 to rotate within the safe stroke range, and when the wind decreases, the flow guide plate 4 and the mounting frame 3 can return to their original positions under their own gravity.

[0032] To ensure a simple and reliable structure, ease of processing and assembly, and improved overall rainwater drainage, in the preferred embodiment, under natural conditions, reference plane one and reference plane two are parallel or coplanar. This means that the drainage direction of the guide channel 21 and the guide cover plate 4 are completely different. It is understood that the drainage surface in this invention is mainly composed of the guide channel 21 and the guide cover plate 4. As long as the combination of the two drainage structures is leak-proof, the drainage surfaces do not need to be perfectly parallel. For example, in strong winds, the wind will cause the guide cover plate 4 to rotate upwards around the hinge axis, and the drainage surface corresponding to the guide cover plate 4 will vary and adjust within a certain rotation angle range. In some alternative embodiments, under natural conditions, reference plane one and reference plane two may not be parallel, with a small angle deviation. The specific angle can be determined comprehensively based on the rain-blocking effect and wind resistance performance.

[0033] In a preferred embodiment, the mounting frame 3 is a rectangular frame composed of transverse beams and longitudinal beams. The guide cover 4 is fixedly installed within the inner ring area enclosed by the rectangular frame. The center lines of the transverse beams and longitudinal beams together define a reference plane three, which is parallel to or coplanar with reference plane two. The front end face of the guide channel 21 is flush with the front end face of the guide support pipe 2, and the rear end face of the guide channel 21 is flush with the rear end face of the guide support pipe 2. There are preset distances between the front end face of the guide support pipe 2 and the inner ring end wall of the rectangular frame, and between the rear end face of the guide support pipe 2 and the inner ring end wall of the rectangular frame. These preset distances can be determined comprehensively based on the rotation space required when the mounting frame 3 rotates around the hinge axis and the space required for the drainage channel in this area. This design effectively ensures the reliability of the overall rotation structure of the guide cover 4 and the mounting frame 3, and also facilitates the smooth discharge of rainwater. In some alternative embodiments, the mounting frame 3 may also have other structural forms or be irregular in shape, as long as the drainage structure formed by the combination of the guide channel 21 and the guide cover 4 can meet the rainproof effect, and the mounting frame 3 and the guide cover 4 can rotate normally around the hinge axis under strong wind.

[0034] In a preferred embodiment, multiple flow guide tubes 2 are evenly spaced, and multiple flow guide covers 4 are evenly spaced, which makes the force more balanced and easier to process and manufacture.

[0035] In a preferred embodiment, the stroke limiting member 8 enables the front end of the guide cover 4 to be limited to the area below the plane containing the top edge of the oblique outer wall 20 of the guide support tube 2 (using the lower surface of the guide cover 4 as the reference). The plane containing the top edge of the oblique outer wall 20 of the guide support tube 2 refers to the reference plane defined by the top edges of the oblique outer walls 20 of all the guide support tubes 2. Since the hinge axis is located in the rear region of the guide cover 4, as long as the front end of the guide cover 4 does not extend upward beyond the top edge of the oblique outer wall 20 of the guide support tube 2, the guide cover 4 as a whole will not extend upward beyond the top edge of the oblique outer wall 20 of the guide support tube 2. This stroke limiting design helps to ensure the rain-blocking effect of the guide cover 4 at its extreme position, that is, to ensure that in rainy weather and strong winds, the obliquely falling rainwater will not pass between adjacent guide support tubes 2.

[0036] In a preferred embodiment, the support frame includes a support column 1, a mounting frame 5, a strut 6, and positioning bolts 7. The axis of the support column 1 is arranged vertically, and at least two support columns 1 are provided and spaced apart in the left-right direction. The rear end of the mounting frame 5 is hinged to the upper end of the support column 1, and there is a second hinge axis between them. The second hinge axis is parallel to the first hinge axis. Multiple flow guide tubes 2 are fixed on the mounting frame 5. The rear side of the mounting frame 3 can be hinged to the support column 1 or to the mounting frame 5. At least two struts 6 are provided, and one end of the strut 6 is connected to the middle of the mounting frame 5. The support rod 6 and the support column 1 are hinged and share a hinge axis three. The other end of the support rod 6 has a insertion hole 60. The center lines of both the hinge axis three and the insertion hole 60 are parallel to the hinge axis two. The support column 1 has multiple positioning holes 10 spaced apart along its axis. The center lines of the positioning holes 10 are parallel to the hinge axis two. The insertion hole 60 can be directly opposite any of the positioning holes 10. Positioning bolts 7 are inserted into the insertion hole 60 and the positioning hole 10 directly opposite it to connect the support rod 6 and the support column 1. Either the insertion hole 60 or the positioning hole 10 can be a threaded hole. This design allows for adjustment of the angle between the reference plane one and the horizontal plane. Positioning holes 10 at appropriate heights can be selected to match and connect with insertion holes 60 via positioning bolts 7, depending on the actual situation. This design improves the wind resistance of the canopy and ensures that rainwater in the drainage channel 21 and on the drainage cover plate 4 can flow quickly and smoothly to the ground.

[0037] The travel limiting component 8 is preferably a limiting rope, with one end fixedly connected to the front end of the mounting frame 3 and the other end fixedly connected to the front end of the mounting bracket 5. It is understood that the travel limiting component 8 has various alternative embodiments. Limiting protrusions, limiting blocks, and other structural components can be added to the rotational mating surface where the hinge axis is located. Various limiting blocks and limiting protrusions can also be added to the front ends of the mounting frame 3 and the mounting bracket 5. To improve structural reliability, depending on the implementation of the travel limiting component 8, a shock-absorbing structure can be added. For example, in this invention, the limiting rope is mainly used to limit the upward rotational travel of the mounting frame 3. This limiting rope is a flexible connection in this application, and generally, no additional shock-absorbing structure is needed. The downward rotational travel of the mounting frame 3 is limited by the top position of the guide channel 21. Since the top position of the guide channel 21 is a rigid structure, a rubber pad or spring is generally required as a shock-absorbing structure.

[0038] In a preferred embodiment, the outer oblique wall 20 of the flow guide tube 2 is provided with multiple through holes 22, which are spaced apart along the length of the flow guide tube 2. The inner side of the flow channel 21 is connected to the inner cavity of the flow guide tube 2 through the through holes 22. The front end of the flow guide tube 2 is open, while the rear end is not mandatory and can be closed or remain open. When there is too much rainwater in the flow channel 21, the rainwater can flow into the flow guide tube 2 and be discharged from the front end of the flow guide tube 2, thereby preventing rainwater from overflowing from the top wall of the side of the flow channel 21 and affecting the rain-blocking effect.

[0039] In a preferred embodiment, the cross-section of the upper surface of the guide cover 4 is V-shaped. This V-shaped cross-section allows the guide cover 4 to more effectively block rain and guide rainwater down to the ground, reducing the drainage volume of the guide channel 21 and preventing rainwater from overflowing from the side top wall of the guide channel 21, thus affecting the rain-blocking effect. The cross-sectional shape of the guide cover 4 also serves as a wind guide, allowing wind to more easily pass through the ventilation gap formed between the lower surface of the guide cover 4 and the top wall of the guide channel 21.

[0040] In a preferred embodiment, the lower surface of the flow guide cover 4 is integrally formed with a plurality of strip-shaped protrusions 40 and a plurality of strip-shaped protrusions 41. The extension direction of the strip-shaped protrusions 40 is consistent with the length direction of the flow guide cover 4, and the extension direction of the strip-shaped protrusions 41 is perpendicular to the length direction of the flow guide cover 4. In this way, the flow guide cover 4 is not easily deformed, ensuring the structural reliability under strong wind conditions.
