Description

Technical Field

[0001] This utility model relates to the field of roof exhaust technology, and more specifically, it relates to a roof exhaust pipe support structure. Background Technology

[0002] Roof ventilation structure design is a technical measure taken for roll roofs where it is difficult to dry the closed insulation layer. Its core technology is to set up ventilation channels inside the insulation layer and leveling layer, so that excess moisture in the base layer can be discharged into the atmosphere through this ventilation structure. This can effectively reduce the blistering of the roll waterproofing layer, and also inhibit the cracking of the roll and roof leakage.

[0003] Existing roof vent pipe support blocks are generally constructed by cast-in-place. The vent pipes are usually T-shaped pipes with the opening facing downwards. Although T-shaped pipes can effectively vent and waterproof, when there is too much moisture in the environment, the moisture may flow into the roof in the opposite direction through the T-shaped pipes, increasing the moisture content in the roof insulation layer.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a roof exhaust pipe support structure, which solves the problem that water vapor can easily flow back into the roof in the existing roof exhaust pipe support structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The embodiment of this application provides a roof exhaust pipe support structure, including a roof, a support base is provided on the roof, a first exhaust groove is provided vertically through the middle of the support base, a longitudinal exhaust pipe is provided in the first exhaust groove, a T-shaped pipe is connected to the top of the longitudinal exhaust pipe, the T-shaped pipe includes two mutually symmetrical exhaust ports, the exhaust ports face downwards, and a steam-water separator is provided on the exhaust ports.

[0007] In one embodiment, the steam-water separator is configured to be tilted.

[0008] In one embodiment, the upper part of the longitudinal exhaust pipe is provided with a first thread, the T-shaped pipe includes a connecting pipe, the connecting pipe is provided with a second thread, and the first thread and the second thread are threadedly connected.

[0009] In one embodiment, a first sealing ring is provided at the connection between the pier and the roof, a second sealing ring is provided at the connection between the first exhaust groove and the longitudinal exhaust pipe, and a third sealing ring is provided at the connection between the longitudinal exhaust pipe and the connecting pipe.

[0010] In one embodiment, the steam-water separator is a louvered separator.

[0011] In one embodiment, the roof comprises, from bottom to top, a slope-forming layer, a leveling layer, an insulation layer, a waterproof layer, and an isolation layer. A second vent is provided on the roof, extending downward from the top of the roof to the insulation layer. A transverse vent is provided within the insulation layer, and multiple vent holes are evenly distributed on the transverse vent. A longitudinal vent is adapted to the second vent and connected to the transverse vent. The first vent corresponds to the second vent, and the longitudinal vent extends upward from the first vent.

[0012] In summary, this utility model has the following beneficial effects: By connecting a T-shaped pipe to the top of the exhaust pipe, the two exhaust ports of the T-shaped pipe face downwards, which can prevent rainwater from entering the exhaust pipe on rainy days. By setting a vapor-water separator on the exhaust port, when there is a lot of water vapor in the environment and it diffuses towards the exhaust port, the vapor-water separator can block the moisture in the water vapor and prevent excessive water vapor from entering the exhaust pipe and roof from the outside.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 and Figure 2As shown, an embodiment of this application provides a roof exhaust pipe support structure, including a roof 1, a support 2 on the roof 1, an exhaust groove running vertically through the middle of the support 2, a longitudinal exhaust pipe 21 inside the exhaust groove, a T-shaped pipe 211 connected to the top of the longitudinal exhaust pipe 21, the T-shaped pipe 211 including two symmetrical exhaust ports 2111, the exhaust ports 2111 facing downwards, and a steam-water separator 21111 provided on the exhaust ports 2111.

[0018] During operation, the water vapor inside the roof 1 rises along the longitudinal exhaust pipe 21 and is discharged downward through the exhaust port 2111.

[0019] The above structure, by connecting a T-shaped pipe 211 to the top of the exhaust pipe so that the two exhaust ports 2111 of the T-shaped pipe 211 face downwards, can prevent rainwater from entering the exhaust pipe on rainy days. A vapor-water separator 21111 is installed on the exhaust port 2111 so that when there is a lot of water vapor in the environment and it diffuses towards the exhaust port 2111, the vapor-water separator 21111 can block the moisture in the water vapor and prevent excessive water vapor from entering the exhaust pipe and roof from the outside.

[0020] In this embodiment, the steam-water separator 21111 is configured to be inclined.

[0021] The above structure, by setting the steam-water separator 21111 to be inclined, makes it easy for water vapor to slide down under the action of gravity after it accumulates, which can prevent excessive water vapor accumulation on the steam-water separator 21111 from affecting the exhaust.

[0022] In this embodiment, the upper part of the longitudinal exhaust pipe 21 is provided with a first thread, the T-shaped pipe 211 includes a connecting pipe 2112, the connecting pipe 2112 is provided with a second thread, and the first thread and the second thread are threadedly connected.

[0023] The above structure is designed such that by setting a first thread and a second thread on the longitudinal exhaust pipe 21 and the T-shaped pipe 211 respectively, the T-shaped pipe 211 can be unscrewed from the longitudinal exhaust pipe 21. If the T-shaped pipe 211 is damaged after long-term use, it can be replaced.

[0024] In this embodiment, a first sealing ring is provided at the connection between the pier 2 and the roof 1, a second sealing ring is provided at the connection between the first exhaust groove and the longitudinal exhaust pipe 21, and a third sealing ring is provided at the connection between the longitudinal exhaust pipe 21 and the connecting pipe 2112.

[0025] The above-mentioned structure is designed with a first sealing ring at the connection between the pier 2 and the roof 1, a second sealing ring at the connection between the first exhaust groove and the longitudinal exhaust pipe 21, and a third sealing ring at the connection between the longitudinal exhaust pipe 21 and the connecting pipe 2112, which makes the roof exhaust pipe support structure more waterproof.

[0026] In this embodiment, the steam-water separator 21111 is a louvered separator.

[0027] Specifically, the louver separator is composed of many parallel corrugated thin steel plates with a thickness of 0.8-1.2mm. The distance between two adjacent corrugated plates is 10mm, and they are fixed with a steel plate frame of 2-3mm thickness. Small water droplets in the water vapor are thrown onto the plate wall under the action of centrifugal force, inertial force and gravity. Under the action of adhesion force, the water droplets adhere to the corrugated plates to form a water film. Under the action of gravity, the water droplets accumulate and fall.

[0028] In this embodiment, the roof 1 includes, from bottom to top, a slope-forming layer 11, a leveling layer 12, an insulation layer 13, a waterproof layer 14, and an isolation layer 15. A second exhaust channel is provided on the roof 1, extending downward from the top of the roof 1 to the insulation layer 13. A horizontal exhaust pipe 131 is provided inside the insulation layer 13, and multiple ventilation holes are evenly provided on the horizontal exhaust pipe 131. A vertical exhaust pipe 21 is adapted to the second exhaust channel and is connected to the horizontal exhaust pipe 131. The first exhaust channel corresponds to the second exhaust channel, and the vertical exhaust pipe 21 extends upward from the first exhaust channel.

[0029] During operation, the moisture inside the insulation layer 13 enters the horizontal exhaust pipe 131 through the vent on the horizontal exhaust pipe 131, and is discharged upward into the air through the vertical exhaust pipe 21.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
