Description

Technical Field

[0001] The present application relates to the technical field of building ventilation systems, and in particular to a wind-resistant cage-type reinforcement structure. Background Art

[0002] Outdoor air ducts are pipe systems used for air delivery and distribution. They can be classified according to cross-sectional shapes and materials. Common cross-sectional shapes of air ducts include round, rectangular and oblate. Outdoor air ducts are usually installed on the roof, wall or floor of a building to connect indoor air ducts and air supply structures. As outdoor air ducts are exposed to the external environment, they are easily affected by natural factors such as wind and rain.

[0003] Traditional duct installation mostly uses clamps to fix the duct to the building. The duct installation structure is unstable and easily affected by wind from all directions, which can cause severe vibration and shaking, causing the clamps at the joints of the duct hoisted in a single direction to fall off or the duct to fall off. Its wind resistance is not ideal and there is a great safety hazard. Utility Model Content

[0004] In order to improve the stability of the air duct installation structure, the present application provides a wind-resistant cage-type reinforcement structure.

[0005] The present application provides a wind-resistant cage reinforcement structure, which adopts the following technical solutions:

[0006] A wind-resistant cage reinforcement structure, comprising:

[0007] A fixed component is fixed to the wall;

[0008] An annular frame is fixed to the fixing assembly, the annular frame is annularly arranged around the outer wall of the air duct, and a plurality of annular frames are provided and distributed along the axial direction of the air duct;

[0009] A connecting piece is used to connect adjacent annular frames, and the connecting piece is arranged around the outer wall of the air duct.

[0010] By adopting the above technical scheme, the fixing component is fixed on the wall to provide a direct anchor point for the installation of the air duct, the annular frame is installed and fixed to the fixing component, the air duct is installed in the annular frame, the annular frame is arranged around the outer wall of the air duct and distributed along the axial direction of the air duct to disperse the wind pressure, provide radial support for the air duct, reduce the possibility of bending or twisting of the air duct under the action of wind, and enhance the structural stability of the air duct. The connecting piece connects adjacent annular frames together to form a continuous supporting structure, strengthens the structural connection between the annular frames, and the connecting piece is arranged around the outer wall of the air duct to form a cage shape, thereby enhancing the wind resistance of the annular frame and improving the structural stability of the air duct installation.

[0011] Optionally, the annular frame includes a first rod and a second rod, the first rod is fixed to the fixing assembly, the first rod and the second rod are symmetrically distributed in pairs, both ends of the second rod are respectively fixed to the symmetrically arranged first rods, the first rod and the second rod are arranged to form a fixing opening for installing the air duct, and both ends of the connecting member are respectively fixed to the adjacent first rods.

[0012] By adopting the above technical solution, the air duct is installed in the fixed opening, the pipe wall of the air duct is against the side wall of the fixed opening, the first rod and the second rod limit the position of the air duct, and the symmetrical arrangement of the first rod and the second rod makes the force on the air duct uniform in all directions, reduces the stress concentration of the air duct, and improves the balance and stability of the air duct structure.

[0013] Optionally, the annular frames are distributed equidistantly.

[0014] By adopting the above technical solution, the equidistantly arranged annular frames can evenly disperse the wind load on the air duct, reduce local stress, and reduce the possibility of excessive pressure on the air duct at certain points causing deformation or loosening of the installation structure, thereby improving the stability of the air duct installation structure.

[0015] Optionally, the distance between adjacent annular frames does not exceed 3 meters.

[0016] By adopting the above technical solution, the 3-meter spacing is set based on the safety factor, so that the air duct has a sufficient support frequency between the supporting points to maintain the stability of the structure and improve the safety of the air duct installation.

[0017] Optionally, the fixing assembly includes a rear embedded plate, a fixing piece and a locking piece, the fixing piece is inserted and fixed to the wall, the rear embedded plate is provided with an insertion opening, the fixing piece is inserted into the insertion opening, the rear embedded plate is against the wall, the locking piece is threadedly connected to the fixing piece, and the locking piece is against the side of the rear embedded plate away from the wall.

[0018] By adopting the above technical solution, the fixing part is fixed in the wall, the fixing part is inserted into the insertion opening, and the fixing part is tightly combined with the rear embedded plate through the insertion opening. The penetrating connection provides strong support, reduces the possibility of lateral displacement between the wall and the rear embedded plate, and the threaded cooperation between the locking part and the fixing part fixes the rear embedded plate on the wall, increases the axial tightening force, and reduces the possibility of loosening of the rear embedded plate. At the same time, the reverse force of the locking part on the rear embedded plate increases the friction force, enhances the contact stability between the wall and the rear embedded plate, thereby reducing the possibility of sliding of the rear embedded plate with the wall due to vibration or load, and improves the connection stability between the fixing component and the wall.

[0019] Optionally, one end of the annular frame away from the wall is connected to a support member, and one end of the support member away from the annular frame is fixed to a fixing assembly.

[0020] By adopting the above technical solution, the support member creates a support structure between the annular frame and the fixed component, thereby increasing the rigidity of the structure and reducing the possibility of deformation of the annular frame due to load.

[0021] Optionally, the support member and the annular frame form an angle of 30°.

[0022] By adopting the above technical solution, the 30° angle support helps to transmit and disperse the force acting on the structure. Due to the principle of force decomposition in mechanics, a force can be decomposed into two components parallel and perpendicular to the support. The 30° angle support allows the vertical component to be directly transmitted to the support point of the structure, while the horizontal component can be resisted by the supporting structure, reducing the possibility of the annular frame tipping over or becoming unstable and improving the overall stability of the structure.

[0023] Optionally, the annular frame is connected to a reinforcing member, and one end of the reinforcing member away from the annular frame is fixed to the supporting member.

[0024] By adopting the above technical solution, for a structure such as an annular frame that may be subjected to large annular and radial stresses, the annular frame is prone to deformation when the force is too large. The reinforcement disperses the stress from the annular frame to a wider area, reduces local stress concentration, improves the durability of the structure, enhances the overall stiffness of the structure, and thereby improves the stability of the duct installation structure.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The fixing assembly is fixed on the wall to provide a direct anchor point for the installation of the air duct. The annular frame is installed and fixed on the fixing assembly. The air duct is installed in the annular frame. The annular frame is arranged around the outer wall of the air duct and distributed along the axial direction of the air duct to disperse the wind pressure and provide radial support for the air duct, thereby reducing the possibility of bending or twisting of the air duct under the action of wind force and enhancing the structural stability of the air duct. The connecting piece connects the adjacent annular frames to form a continuous support structure, strengthens the structural connection between the annular frames, and the connecting piece is arranged around the outer wall of the air duct to form a cage shape, thereby enhancing the wind resistance of the annular frame and improving the structural stability of the air duct installation;

[0027] 2. Fix the fixing part in the wall, insert the fixing part into the insertion opening, and closely combine the fixing part with the rear embedded plate through the insertion opening. The penetration connection provides strong support, reduces the possibility of lateral displacement between the wall and the rear embedded plate, and the threaded cooperation between the locking part and the fixing part fixes the rear embedded plate on the wall, increases the axial fastening force, and reduces the possibility of loosening of the rear embedded plate. At the same time, the reverse force of the locking part on the rear embedded plate increases the friction force, enhances the contact stability between the wall and the rear embedded plate, thereby reducing the possibility of sliding of the rear embedded plate with the wall due to vibration or load, and improves the connection stability between the fixing component and the wall;

[0028] 3. The support member creates a support structure between the annular frame and the fixed component, increases the rigidity of the structure, and reduces the possibility of deformation of the annular frame due to load. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The embodiment of the present application discloses a wind-resistant cage-type reinforcement structure.

[0037] Reference Figure 1 and Figure 2 A wind-resistant cage reinforcement structure includes a fixing component 1 for fixing on a wall, which provides a stable anchor point for installing an air duct on the wall.

[0038] It also includes an annular frame 2 and a connecting piece 3. The annular frame 2 is fixed to the fixing component 1. The annular frame 2 is annularly arranged around the outer wall of the air duct. The inner wall of the annular frame 2 abuts against the outer wall of the air duct. There are multiple annular frames 2, which are distributed along the axial direction of the air duct. The connecting piece 3 is arranged around the outer wall of the air duct. The connecting piece 3 abuts against the air duct. The connecting pieces 3 are equidistantly distributed. Adjacent annular frames 2 are connected and fixed by the connecting piece 3. In particular, the annular frame 2 located at the place where the air duct penetrates the wall, the side of the annular frame 2 close to the wall is fixed to the connecting piece 3, and the end of the connecting piece 3 away from the annular frame 2 is fixed to the wall.

[0039] The annular frame 2 is installed and fixed on the fixing component 1, one end of the connecting piece 3 is connected to the annular frame 2, and the other end of the connecting piece 3 is connected to the adjacent annular frame 2 or wall. The connection structure between the annular frame 2 and the connecting piece 3 forms a cage frame, forming a continuous supporting structure, strengthening the structural connection between the annular frames 2, and the air duct is installed in the cage frame. The cage frame provides a stable supporting structure for the air duct, reduces the possibility of bending or twisting of the air duct under the action of wind, enhances the wind resistance of the annular frame 2, and improves the stability of the air duct installation structure.

[0040] Along the length direction of the air duct, the annular frame 2 is evenly distributed on the outer wall of the air duct, evenly dispersing the wind load on the air duct, reducing local stress, and reducing the possibility of deformation or loosening of the installation structure caused by excessive pressure on certain points of the air duct, thereby improving the stability of the air duct installation structure.

[0041] To improve the installation safety of the annular frame, the spacing between adjacent annular frames 2 is no more than 3 meters, so that the air duct has sufficient support frequency between the support points, improves the installation stability of the annular frame 2, and improves the safety of the air duct installation.

[0042] The annular frame 2 includes a first rod 21 and a second rod 22, the extension direction of the first rod 21 is perpendicular to the wall surface, one end of the first rod 21 is fixed to the fixing assembly 1, the number of the first rod 21 is two, and they are parallel to each other, the two ends of the second rod 22 are respectively fixed to the side of the two first rods 21 close to each other, the extension direction of the second rod 22 is perpendicular to the extension direction of the first rod 21, the number of the second rod 22 is two, and they are parallel to each other, the first rod 21 and the second rod 22 are symmetrically distributed in pairs, the first rod 21 and the second rod 22 are surrounded by a fixing port for installing an air duct, the side wall of the air duct abuts against the first rod 21 and the second rod 22, the two ends of the connecting member 3 are respectively fixed to the adjacent first rod 21, the extension direction of the connecting member 3 is perpendicular to the plane formed by the first rod 21 and the second rod 22, and the extension direction of the first rod 21 is perpendicular to the plane formed by the second rod 22 and the connecting member 3.

[0043] When installing the air duct, the air duct is inserted into the fixing opening, and the pipe wall of the air duct is against the side wall of the fixing opening. The first rod 21 and the second rod 22 limit the position of the air duct, and the symmetrical arrangement of the first rod 21 and the second rod 22 makes the air duct evenly stressed in all directions, reduces the stress concentration of the air duct, and improves the balance and stability of the air duct structure.

[0044] One end of the first rod 21 away from the wall is fixedly connected to the support member 4, and the support member 4 is fixed to the side of the first rod 21 away from the second rod 22, and the end of the support member 4 away from the first rod 21 is fixed to the fixing assembly 1, and a stable triangular structure is formed among the support member 4, the first rod 21 and the wall, thereby increasing the rigidity of the structure and reducing the possibility of deformation of the annular frame 2 due to load.

[0045] The support member 4 forms an angle of 30° with the first rod member 21. The extension direction of the first rod member 21 is perpendicular to the wall, thereby forming a counter-support. The support member 4 disperses the force from the first rod member 21 not only along the vertical direction but also along an oblique component, thereby balancing the load of the first rod member 21 and enhancing the structural stability of the first rod member 21.

[0046] A reinforcing member 5 is fixedly connected to one side of the first rod 21 close to the support member 4. An end of the reinforcing member 5 away from the first rod 21 is fixed to the support member 4 connected to the first rod 21 in the adjacent annular frame. The reinforcing member 5 is arranged at an angle and is located in the plane formed by the second rod 22 and the connecting member 3.

[0047] The reinforcement member 5 connects the first rod member 21 in the adjacently distributed annular frame 2 with the support member 4 connected to the first rod member 21 in the adjacent annular frame 2, further enhancing the structural connection stability between the adjacent frames. The reinforcement member 5 is inclined, so that the annular frame, the connecting member 3 and the reinforcement member 5 form a stable triangle with the reinforcement member 5 as the inclined edge, thereby further improving the stability of the air duct installation.

[0048] Reference Figure 3 and Figure 4The fixing assembly 1 includes a rear embedded plate 11, a fixing member 12 and a locking member 13. The rear embedded plate 11 is provided in plurality, and each rear embedded plate 11 is allocated with a plurality of fixing members 12 and a plurality of locking members 13. In the present embodiment, specifically, one rear embedded plate 11, five fixing members 12 and five locking members 13 form a group, and each group is connected to one end of the first rod 21 or the support member 4 by welding. The five fixing members 12 are evenly distributed along the center of the rear embedded plate 11 at equal distances, and the locking member 13 is threadedly connected to the fixing member 12. The rear embedded plate 11 is provided with an insertion opening 111, and the fixing member 12 is inserted into the insertion opening 111. The rear embedded plate 11 is against the wall, and the locking member 13 is against the side of the rear embedded plate 11 away from the wall. The rear embedded plate 11 is clamped between the wall and the locking member 13, and the fixing member 12 is inserted and fixed to the wall.

[0049] When installing the fixing component 1, fix the fixing part 12 in the wall, insert the fixing part 12 into the insertion opening 111, insert the fixing part 12 into the rear embedded plate 11, and place the locking part 13 at the end of the rear embedded plate 11 away from the wall. The locking part 13 cooperates with the thread of the fixing part 12, and the locking part 13 is screwed so that the two sides of the rear embedded plate 11 are respectively pressed against the locking part 13 and the wall, and the rear template is fixed on the wall. The locking part 13 increases the friction force of the reverse action force of the rear embedded plate 11, enhances the contact stability between the wall and the rear embedded plate 11, and thus reduces the possibility of the rear embedded plate 11 sliding with the wall due to vibration or load, and improves the connection stability between the fixing component 1 and the wall. When the first rod 21 and the support member 4 are fixed on different rear embedded plates 11, the possibility of sliding and falling of the first rod 21 and the support member 4 is reduced, thereby improving the stability of the air duct installation structure.

[0050] The implementation principle of a wind-resistant cage-type reinforcement structure in an embodiment of the present application is as follows: the fixing member 12 is fixed to the wall, and the rear embedded plate 11 is fixed to the wall by a threaded connection between the fixing member 12 and the locking member 13. The first rod member 21 and the support member 4 are respectively fixedly installed on different rear embedded plates 11 to provide a direct anchor point for the installation of the air duct. The first rod member 21 and the second rod member 22 are annularly arranged around the outer wall of the air duct and distributed along the axial direction of the air duct to disperse the wind pressure, provide radial support for the air duct, and reduce the possibility of bending or twisting of the air duct under the action of wind. The connecting member 3 connects adjacent annular frames 2 together to form a continuous support structure to strengthen the structural connection between the annular frames 2. The connecting member 3 is arranged around the outer wall of the air duct to form a cage shape. The support member 4 and the reinforcement member 5 form a counter-support force for the air duct, further enhancing the wind resistance of the annular frame 2, improving the stability of the air duct installation structure, and reducing the possibility of the air duct falling.

[0051] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn.
