Description

Technical Field

[0001] This utility model relates to a support structure, specifically, to a support structure for a fire exhaust duct. Background Technology

[0002] Fire exhaust ducts are a type of safety facility inside buildings. They are primarily used to prevent the spread of smoke within the building during a fire, while also expelling stale air from the building to the outside, ensuring good air quality inside. Fire exhaust ducts are typically installed on the interior ceiling and therefore require support to prevent them from becoming loose.

[0003] In existing technologies, smoke exhaust ducts generally use unidirectional support, that is, a support plate is installed at the bottom of the smoke exhaust duct. This support method can achieve the basic support function of the smoke exhaust duct, but when encountering violent shaking such as earthquakes, the smoke exhaust duct is prone to shaking, the connection between two adjacent smoke exhaust ducts becomes loose, causing smoke to flow out and affecting the smoke exhaust effect. This is a shortcoming of existing technologies. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a fire smoke exhaust duct support structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a fire-fighting smoke exhaust duct support structure, including a first vertical rod and a second vertical rod fixed to the lower part of the ceiling. The outer surfaces of the first vertical rod and the second vertical rod are provided with external threads. The first vertical rod and the second vertical rod are arranged in parallel. A first support plate is vertically fixed between the first vertical rod and the second vertical rod. A smoke exhaust duct is provided on the first support plate. A second support plate is provided on the upper part of the smoke exhaust duct. A first adjustment hole is provided at one end of the second support plate. The first vertical rod passes through the first adjustment hole. The first vertical rod is locked and fixed on both sides of the second support plate by a first nut. A second adjustment hole is provided at the other end of the second support plate. The second vertical rod passes through the second adjustment hole. The second vertical rod is locked and fixed on both sides of the second support plate by a second nut.

[0006] A further improvement of this utility model is that a first support hole is provided at one end of the first support plate, the first vertical rod passes through the first support hole, and the first vertical rod is locked and fixed on both sides of the first support plate by a third nut; a second support hole is provided at the other end of the first support plate, the second vertical rod passes through the second support hole, and the second vertical rod is locked and fixed on both sides of the first support plate by a fourth nut.

[0007] A further improvement of this utility model is that the second support plate is provided with a limiting mechanism for limiting the smoke exhaust duct. The limiting mechanism includes a left limiting plate and a right limiting plate. The left limiting plate is fixed to the first support plate, and the right limiting plate is connected to the first support plate through an elastic component.

[0008] A further improvement of this utility model is that the elastic component includes a spring and a fixing plate, one end of the spring is fixed to the right limiting plate, the other end of the spring is fixed to the fixing plate, and the fixing plate is mounted on the first support plate.

[0009] A further improvement of this utility model is that a slider is provided at the bottom of the right limiting plate, and a groove is provided on the upper surface of the first support plate, with the slider cooperating with the groove.

[0010] A further improvement of this utility model is that the left limiting plate is an "L" shaped plate and the right limiting plate is an "L" shaped plate.

[0011] The beneficial effects of this utility model are as follows: This application achieves support for the smoke exhaust duct through the first support plate, and the second support plate achieves a more secure fixation of the smoke exhaust duct. Pressing the second support plate tightly onto the smoke exhaust duct ensures that the position of the smoke exhaust duct will not move, further ensuring that the connection between adjacent smoke exhaust ducts always remains firm, avoiding the adverse effects of smoke flow on the human body. At the same time, the setting of the second support plate allows the support structure to be precisely adjusted according to the size of the duct and the installation position, meeting the on-site installation requirements.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0018] Example 1: As Figure 1 As shown, a fire-fighting smoke exhaust duct support structure includes a first vertical rod 2 and a second vertical rod 3 fixed to the lower part of a ceiling 1. Both the first vertical rod 2 and the second vertical rod 3 have external threads on their outer surfaces. The first vertical rod 2 and the second vertical rod 3 are arranged in parallel. A first support plate 4 is vertically fixed between the first vertical rod 2 and the second vertical rod 3. A smoke exhaust duct 5 is mounted on the first support plate 4. In this application, the first support plate 4 provides support for the smoke exhaust duct 5. The top ends of the first vertical rod 2 and the second vertical rod 3 are fixed to the ceiling 1 using expansion bolts, ensuring the stability and safety of the entire support structure.

[0019] To more securely fix the exhaust duct 5, a second support plate 6 is provided on the upper part of the exhaust duct 5. One end of the second support plate 6 has a first adjustment hole (not shown in the figure), through which the first vertical rod 2 passes. The first vertical rod 2 is locked and fixed on both sides of the second support plate 6 by first nuts 7. The other end of the second support plate 6 has a second adjustment hole (not shown in the figure), through which the second vertical rod 3 passes. The second vertical rod 3 is locked and fixed on both sides of the second support plate 6 by second nuts 8. In actual operation, the exhaust duct 5 should first be placed on the first support plate 4. Then, one end of the second support plate 6 is adjusted to move vertically along the first vertical rod 2, and the other end of the second support plate 6 is adjusted to move vertically along the second vertical rod 3, ensuring that the second support plate 6 can press firmly onto the exhaust duct 5. Finally, the first nuts 7 and the second nuts 8 are locked and fixed respectively. By pressing the second support plate 6 onto the smoke exhaust duct 5, the position of the smoke exhaust duct 5 is ensured to remain stable, further ensuring that the connection between adjacent smoke exhaust ducts remains secure and avoiding adverse effects on the human body from the smoke exhaust.

[0020] Furthermore, the connection between the first support plate 4 and the first vertical rod 2 and the second vertical rod 3 can be achieved by welding or by a detachable fixed connection, such as bolt connection. In this application, the connection between the first support plate 4 and the first vertical rod 2 and the second vertical rod 3 is as follows: one end of the first support plate 4 is provided with a first support hole (not shown in the figure), the first vertical rod 2 passes through the first support hole, and the first vertical rod 2 is locked and fixed on both sides of the first support plate 4 by a third nut 9; the other end of the first support plate 4 is provided with a second support hole (not shown in the figure), the second vertical rod 3 passes through the second support hole, and the second vertical rod 3 is locked and fixed on both sides of the first support plate 4 by a fourth nut 10. By adjusting one end of the first support plate 4 to move vertically along the first vertical rod 2, and adjusting the other end of the first support plate 4 to move vertically along the second vertical rod 3, the third nut 9 and the fourth nut 10 are finally fixed respectively. This connection method can change the overall fixed height of the smoke exhaust duct according to actual construction needs.

[0021] Example 2 differs from Example 1 in that, as Figure 2-4 As shown, in order to position the initial location of the exhaust duct, this application provides a limiting mechanism on the second support plate 6 for limiting the exhaust duct. The limiting mechanism includes a left limiting plate 111 and a right limiting plate 112. The left limiting plate 111 is fixed to the first support plate, and the right limiting plate 112 is connected to the first support plate 6 through an elastic component. The left limiting plate 111 and the right limiting plate 112 are used to more accurately limit and fix the exhaust duct 5, preventing it from shaking or shifting during operation.

[0022] The elastic component includes a spring 113 and a fixing plate 114. One end of the spring 113 is fixed to the right limiting plate 112, and the other end of the spring 113 is fixed to the fixing plate 114. The fixing plate 114 is mounted on the first support plate. This design allows the right limiting plate to adaptively adjust according to the actual size of the exhaust duct under the elastic force of the spring, ensuring the limiting effect.

[0023] To facilitate the sliding and adjustment of the right limiting plate 112, a slider 115 is provided at the bottom of the right limiting plate 112, and a groove 116 is provided on the upper surface of the first support plate 4. The slider 115 cooperates with the groove 116 to ensure that the right limiting plate 112 can slide smoothly and to limit its sliding range.

[0024] The left limiting plate 111 and the right limiting plate 112 are both L-shaped, which enhance the strength of the structure, facilitate a tight fit with the air duct, and provide all-round support and protection.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
