Description

Technical Field

[0001] This utility model relates to the field of air conditioning engineering technology, specifically to a ventilation installation structure for air conditioning engineering. Background Technology

[0002] Central air conditioning projects are typically systems that provide centralized air conditioning for large buildings. Some residents also choose central air conditioning in their homes due to personal preference or the size of their houses. Central air conditioning mainly works in concert with refrigeration units, ventilation ducts, and terminal equipment to regulate indoor temperature, humidity, and air quality. It has the characteristics of wide coverage and high regulation efficiency, and is one of the indispensable infrastructures of modern buildings.

[0003] The installation structure of central air conditioning ventilation ducts usually uses a support frame as the core load-bearing component. The support frame is connected and fixed to the main building through support components such as top hangers and angle steel brackets. The ventilation ducts are placed on the support frame. Some structures will have auxiliary components at the contact position between the support frame and the ventilation duct to meet the requirements of installation stability and vibration reduction.

[0004] In existing technologies, to achieve vibration reduction, the installation structure of central air conditioning ventilation ducts often uses adhesive pads on the top of the support frame. However, after long-term use, the adhesive pads are prone to hardening and cracking due to aging and drying, resulting in a decrease in seismic resistance. Vibrations are transmitted to the building ceiling through the support frame and support components, which may not only cause noise complaints but also loosen the installation structure due to long-term vibration. At the same time, the adhesive pads are directly pasted on the support frame, making the replacement process cumbersome and inconvenient for maintenance. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a ventilation installation structure for air conditioning engineering to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilation installation structure for an air conditioning project, comprising a support frame, an extension plate connected to one side of the support frame, a lifting bolt penetrating the bottom of the extension plate, and a top block connected to the top of the lifting bolt; a reinforcing plate connected inside the extension plate; an installation plate connected to the other side of the support frame, and a rubber pad connected to the top of the installation plate; and a limit bolt connecting the installation plate and the extension plate.

[0007] By adopting the above technical solution, the rubber pad is placed on a detachable mounting plate, and together with components such as the expansion plate and lifting bolts, the rubber pad can be easily replaced. The reinforcing plate enhances the structural strength, and the top block reduces wear on the ventilation slots, thereby improving the overall stability and ease of maintenance of the installation structure.

[0008] Furthermore, the longitudinal section of the extension plate is "n"-shaped, and the reinforcing plate is trapezoidal.

[0009] By adopting the above technical solution, the expansion plate provides space for the installation of the lifting bolts and the limiting bolts, and the trapezoidal reinforcing plate can distribute the load on the expansion plate, reduce its bending deformation, and improve the load-bearing capacity of the expansion plate.

[0010] Furthermore, the mounting plate has a "C"-shaped longitudinal section, and the mounting plate is detachably connected to the support frame and the extension plate.

[0011] By adopting the above technical solution, the C-shaped structure can limit the displacement of the mounting plate to the left and the upward displacement of the right side of the mounting plate, reducing the risk of the mounting plate loosening, while distributing the force on the limit bolts; the detachable design makes it easy to replace the rubber gasket by removing and installing the mounting plate, reducing the complexity of maintenance operations.

[0012] Furthermore, the longitudinal section of the rubber pad is an isosceles trapezoid, and the rubber pad is fixedly connected to the top of the mounting plate by adhesive bonding, and the limiting bolt is threadedly connected to the mounting plate.

[0013] By adopting the above technical solution, the bottom area of ​​the isosceles trapezoidal rubber pad is larger, which increases the bonding area with the mounting plate and helps to reduce the phenomenon of rubber pad falling off; the threaded connection between the limit bolt and the mounting plate can stably limit the horizontal displacement of the mounting plate, improve the installation stability of the mounting plate, and facilitate disassembly and assembly operations.

[0014] Furthermore, the lifting bolt is a high-strength bolt.

[0015] By adopting the above technical solutions, high-strength bolts have high shear and compressive strength, and are not prone to deformation or breakage when lifting ventilation slots, thus ensuring the structural stability of the temporary support process and reducing the risk of support failure.

[0016] Furthermore, multiple lifting bolts and top blocks are provided, and multiple lifting bolts are threadedly connected to the extension plate.

[0017] By adopting the above technical solution, multiple lifting bolts and top blocks can evenly distribute the weight of the ventilation slot, reducing the stress on individual components; the threaded connection with the expansion plate facilitates precise adjustment of the lifting height, ensuring that the ventilation slot is lifted smoothly and reducing the resistance to disassembly and assembly of the mounting plate.

[0018] Furthermore, the top of the top block is arc-shaped.

[0019] By adopting the above technical solution, the arc-shaped top can reduce the hard friction with the ventilation channel during the lifting process, reduce the probability of the ventilation channel surface being worn by sharp edges and corners, and protect the structural integrity of the ventilation channel.

[0020] Furthermore, support components are connected to both sides of the top of the support frame, and the two support components are mirror images of each other.

[0021] By adopting the above technical solution, the support components distributed in a mirror pattern on both sides can disperse the load on the support frame, reduce the structural tilt caused by excessive force on one side, and improve the stability of the connection between the overall structure and the main building.

[0022] Furthermore, the support assembly is a fully threaded rod assembly or an angle steel bracket assembly.

[0023] By adopting the above technical solution, the limitations of this technical solution are small, it can adapt to two support systems, expand the applicability of the structure, and improve its practicality.

[0024] Furthermore, the top block has a T-shaped longitudinal section and penetrates the top of the lifting bolt and is welded and fixed.

[0025] By adopting the above technical solution, the through welding of the T-shaped top block and the lifting bolt increases the contact area between the two, improves the connection strength, reduces the risk of the top block falling off during the lifting process, and ensures the safety of the operation.

[0026] In summary, the present invention has the following main advantages: 1. This utility model, through the setting of mounting plate, rubber pad, and limiting bolt, transfers the rubber pad to the top of the mounting plate instead of directly pasting it to the support frame. When the rubber pad has problems such as aging, it can be replaced by disassembling and assembling the mounting plate, reducing the cumbersomeness of rubber pad replacement. The rubber pad adopts an isosceles trapezoidal structure, and the larger bottom area increases the bonding area with the mounting plate, which helps to reduce the phenomenon of rubber pad falling off. The longitudinal section of the mounting plate is C-shaped, which can limit its own displacement to the left and its own upward displacement to the right, and can distribute the force on the limiting bolt. The limiting bolt forms a stable limit on the mounting plate through threaded connection, further improving the overall stability of the structure. 2. By using lifting bolts and top blocks, this utility model allows the ventilation groove to be temporarily lifted by screwing in the lifting bolts from the bottom of the extension plate before disassembling and assembling the mounting plate. This avoids the problem of excessive disassembly and assembly resistance caused by the ventilation groove pressing on the rubber pad, and reduces the obstruction when the mounting plate is horizontally pulled out or installed. The top of the top block is arc-shaped, making the top of the lifting bolt more rounded, which helps to reduce the phenomenon of the ventilation groove being worn by the sharp edges of the bolt during the lifting process. 3. By setting up a reinforcing plate, which is trapezoidal and connected inside the extension plate, this utility model can enhance the structural strength of the extension plate, reduce the bending deformation of the extension plate during the stress process, provide a more stable support foundation for the overall structure during replacement operations, and indirectly improve the load-bearing capacity and service life of the extension plate.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Example 1: A ventilation installation structure for an air conditioning system, such as Figures 1-5As shown, the system includes a support frame 1. An extension plate 3 is connected to one side of the support frame 1. The extension plate 3 has an "n"-shaped longitudinal section. A reinforcing plate 4, which is trapezoidal, is connected inside the extension plate 3. A lifting bolt 8, a high-strength bolt, passes through the bottom of the extension plate 3. A top block 9, with an arc-shaped top, is connected to the top of the lifting bolt 8. Multiple lifting bolts 8 and multiple top blocks 9 are provided, and all are threadedly connected to the extension plate 3. An mounting plate 5 is connected to the other side of the support frame 1. The mounting plate 5 has a "C"-shaped longitudinal section. The mounting plate 5 is detachably connected to the support frame 1 and the extension plate 3. A rubber pad 6, with an isosceles trapezoidal longitudinal section, is connected to the top of the mounting plate 5 by adhesive. A limit bolt 7 connects the mounting plate 5 and the extension plate 3, and is threadedly connected to the mounting plate 5. When the rubber pad 6 needs to be replaced due to aging, the operator first screws in multiple high-strength bolts from the bottom of the extension plate 3. The lifting bolt 8 and the top block 9 connected to it have a T-shaped longitudinal section and are welded and fixed through the top of the lifting bolt 8, resulting in stronger connection stability and less detachment. The top of the top block 9 is also arc-shaped, which reduces wear on the ventilation slot. As the lifting bolt 8 is screwed in, the top block 9 lifts the ventilation slot to provide temporary support, preventing the ventilation slot from pressing on the rubber pad 6 and causing excessive frictional resistance on the contact surface, thus reducing the resistance of horizontal removal of the mounting plate 5. Then, the worker loosens the limiting bolt 7 and pulls the mounting plate 5 horizontally to the right to complete the disassembly. The worker then horizontally inserts the new mounting plate 5 into the top of the support frame 1 and the extension plate 3, and tightens the limiting bolt 7 to complete the fixation. The longitudinal section of the mounting plate 5 is C-shaped, which can limit its own displacement to the left and upward displacement to the right, distributing the force on the limiting bolt 7. Finally, the worker unscrews the lifting bolt 8, so that the ventilation slot fits with the new rubber pad 6. At this time, the ventilation slot is placed on top of the rubber pad 6, and the rubber pad 6 plays a shock-absorbing role.

[0032] See Figure 1 and Figure 2 In the above embodiment, support components 2 are connected to both sides of the top of the support frame 1. The two support components 2 are mirror images of each other. When installing the central air conditioning ventilation duct, the ventilation duct is lifted to a specified height and temporarily supported by a lifting device. Then, the staff installs the support components 2 on the building ceiling. The support components 2 can be selected as fully threaded rod components or angle steel bracket components according to the actual installation requirements to adapt to different installation systems and ensure that the support frame 1 stably supports the ventilation duct. After the support components 2 are fixed to the building, the rubber pad 6 on the top of the support frame 1 is attached to the bottom of the ventilation duct. At this time, the staff can remove the lifting device, and the support frame 1, support components 2 and rubber pad 6 form a support system to support the ventilation duct.

[0033] Example 2: Based on the above embodiment one, in order to broaden the scope of application, the following settings are now adopted.

[0034] See Figure 1 and Figure 2 In the above embodiments, the support component 2 is a fully threaded rod assembly or an angle steel bracket assembly. This technical solution is applicable to both fully threaded rod support systems and angle steel bracket support systems, and has a wider range of applications.

[0035] Example 3: Based on the above embodiment one, the following settings are now adopted to increase the stability of the structural connection.

[0036] See Figure 4 and Figure 5 In the above embodiment, the top block 9 has a "T" shaped longitudinal section. The top block 9 passes through the top of the lifting bolt 8 and is welded and fixed. The through-welded fixed connection design between the top block 9 and the lifting bolt 8 can effectively reduce the risk of the top block 9 falling off.

[0037] The implementation principle of this utility model is as follows: First, when installing the central air conditioning ventilation duct, the ventilation duct is lifted to a specified height and temporarily supported by a lifting device. Then, the workers install the support component 2 on the building ceiling. The support component 2 can be selected as a fully threaded hanger component or an angle steel bracket component according to the actual installation requirements to adapt to different installation systems and ensure that the support frame 1 stably supports the ventilation duct. After the support component 2 is fixed to the building, the rubber pad 6 on the top of the support frame 1 is attached to the bottom of the ventilation duct. At this time, the workers can remove the lifting device, and the support frame 1, the support component 2 and the rubber pad 6 form a support system to support the ventilation duct. When the rubber pad 6 needs to be replaced due to aging, the workers first screw in multiple high-strength lifting bolts 8 from the bottom of the extension plate 3. The top block 9 connected to the top of the lifting bolt 8 has a T-shaped longitudinal section and is welded and fixed through the top of the lifting bolt 8, resulting in stronger connection stability and making it less prone to falling off. In addition, the top of the top block 9 is arc-shaped, which can reduce wear on the ventilation slot. As the lifting bolts 8 are screwed in, the top block 9 lifts the ventilation slot to provide temporary support, preventing the ventilation slot from pressing on the rubber pad 6 and causing excessive frictional resistance on the contact surface, thereby reducing the horizontal pull of the mounting plate 5. The resistance of the separation; then the staff loosened the limit bolt 7 and pulled the mounting plate 5 horizontally to the right to complete the disassembly; then the staff installed the new mounting plate 5 horizontally into the top of the support frame 1 and the extension plate 3, and tightened the limit bolt 7 to complete the fixation. The longitudinal section of the mounting plate 5 is C-shaped, which can limit its own displacement to the left and upward displacement to the right, and distribute the force on the limit bolt 7; finally, the staff unscrewed the lifting bolt 8 so that the ventilation groove fits with the new rubber pad 6. At this time, the ventilation groove is placed on top of the rubber pad 6, and the rubber pad 6 plays a shock absorption role; The removed lifting bolts 8 can be reused for replacing rubber pads 6 in other similar structures, reducing waste. Furthermore, if the mounting plate 5 is free from defects such as damage or corrosion, the manufacturer can reuse the mounting plate 5. After removing the old rubber pads 6 and performing surface treatments such as grinding, the rubber pads 6 are fixed to the top of the mounting plate 5 in an isosceles trapezoidal structure by adhesive bonding. The larger area at the bottom of the rubber pads 6 can increase the bonding area with the mounting plate 5.
