Description

Technical Field

[0001] This utility model relates to the technical field of building engineering, and in particular to a ventilation structure that does not extend beyond the roof insulation side. Background Technology

[0002] Roof insulation is an important measure to improve indoor comfort and achieve building energy conservation, and the moisture content of the roof insulation layer directly determines the performance of the roof layer and waterproof layer. In order to remove moisture from the insulation layer, the common practice is to install insulation vents that extend out of the roof, through which the collected water vapor is discharged from the insulation layer.

[0003] Extensive practical experience has shown that the effective range of locally installed roof vents is limited, and a significant amount of moisture remains within the insulation layer, leading to cracking of the roof surface and even bulging and leakage of the waterproof layer. Furthermore, excessive installation of roof vents can affect the functionality of the roofs of some public buildings. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a ventilation structure that does not leave the roof insulation side, which has good ventilation effect, is easy to install and has low cost. It can quickly and effectively remove water vapor from the insulation layer, ensure the roof performance and waterproof quality, and optimize the roof's function and application scenarios.

[0005] To achieve the above objectives, this utility model provides a roof insulation-side venting structure, including a building roof layer component. The top of the building roof layer component is provided with a lightweight aggregate concrete slope adjustment layer, the top surface of which is a slope that is high on both sides and low in the middle. The top of the lightweight aggregate concrete slope adjustment layer is provided with an insulation layer, and the interior of the insulation layer is provided with horizontally arranged crisscrossing vent pipes. At the lowest point of the lightweight aggregate concrete slope adjustment layer, there is a roof drainage ditch that communicates with the horizontal vent pipes.

[0006] Preferably, the surface of the horizontal exhaust pipe is evenly distributed with small ventilation holes, but no ventilation holes are provided within a certain length range at one end near the roof drainage ditch.

[0007] Furthermore, a one-way valve is provided at one end of the horizontal exhaust pipe near the roof drainage ditch to prevent water in the roof drainage ditch from flowing back into the horizontal exhaust pipe.

[0008] Preferably, the horizontal exhaust pipe is laid along the slope of the lightweight aggregate concrete slope adjustment layer.

[0009] Furthermore, the horizontal exhaust pipes are arranged in a crisscross pattern with a spacing of 3000mm to 6000mm, and the ventilation holes on the horizontal exhaust pipes are spaced 25mm to 100mm apart.

[0010] Furthermore, the roof drainage ditch is flanked by brick retaining walls, and the top of the roof drainage ditch is covered with a ditch cover.

[0011] Preferably, the top of the insulation layer is provided with a reinforced concrete protective layer, and the top of the roof drainage ditch penetrates through the reinforced concrete protective layer.

[0012] Furthermore, the building roof layer component includes a roof structure layer, the top of which is provided with a leveling layer or a base treatment interface layer, the top of which is provided with a waterproof layer, and the top of which is provided with the lightweight aggregate concrete slope adjustment layer.

[0013] In summary, compared with the prior art, the exhaust structure of this utility model that does not extend beyond the roof insulation side has at least the following beneficial effects: 1. By installing horizontal drainage pipes with vents, all venting structures do not extend beyond the roof layer, achieving unobstructed installation on the roof layer and increasing the roof's functionality and application scenarios.

[0014] 2. The crisscrossing horizontal exhaust pipes with slopes increase the effective range and efficiency of exhaust from the roof insulation layer, and can quickly remove water vapor, avoiding the impact of water vapor on the quality of the roof surface and waterproof layer.

[0015] 3. A one-way valve is creatively installed at the end of the horizontal exhaust pipe near the roof drainage ditch, which provides double protection to ensure that there is no backflow of water into the insulation layer.

[0016] 4. The structure of this utility model is simple and convenient. It forms a horizontal exhaust pipe with a crisscross mesh arrangement inside the insulation board. The horizontal exhaust pipe has a large contact surface with the insulation board and a wide coverage area, which can quickly and effectively remove moisture from the insulation layer and ensure the roof's performance and waterproofing quality.

Detailed Implementation

[0020] 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.

[0021] See below. Figure 1 The exhaust structure of the roof insulation side of this utility model is described in detail.

[0022] The roof-mounted insulation-side venting structure of this utility model includes a building roof layer component 001, which includes a roof structure layer 100. The roof structure layer 100 has a leveling layer or base treatment interface layer 200 on top. The leveling layer or base treatment interface layer 200 has a waterproof layer 300 on top. The waterproof layer 300 has a lightweight aggregate concrete slope adjustment layer 400 on top, with its top surface sloping downwards from the sides to the middle. The lightweight aggregate concrete slope adjustment layer 400 has an insulation layer 503 on top. The insulation layer 503 has horizontally arranged venting pipes 500 arranged in a crisscross pattern inside. At the lowest point of the lightweight aggregate concrete slope adjustment layer 400, a roof drainage ditch 701 connected to the horizontal venting pipes 500 is provided.

[0023] The surface of the horizontal exhaust pipe 500 is evenly distributed with small ventilation holes 501. A one-way valve 502 is installed at one end of the horizontal exhaust pipe 500 near the roof drainage ditch 701. The outer side of the horizontal exhaust pipe 500 is covered with a layer of non-woven fabric. A reinforced concrete protective layer 600 is provided on the top of the insulation layer 503. The top of the roof drainage ditch 701 penetrates the reinforced concrete protective layer 600. The roof drainage ditch 701 is supported by brick retaining walls 800 on both sides, and a ditch cover 702 is provided on the top of the roof drainage ditch 701.

[0024] Furthermore, the horizontal exhaust pipe 500 does not have ventilation holes 501 within a certain length range at one end near the roof drainage ditch 701, and the length range is set according to the slope of the lightweight aggregate concrete slope adjustment layer 400.

[0025] Furthermore, the one-way valve 502 is normally open. It only closes under water pressure when the water level in the roof drain 701 exceeds the bottom of the horizontal vent pipe 500, preventing water in the roof drain 701 from flowing back into the horizontal vent pipe 500. After the water level drops, it returns to its normally open state, providing double protection to ensure that there is no backflow of water into the insulation layer 503.

[0026] Preferably, the spacing between the vent holes 501 on the horizontal exhaust pipe 500 is 25mm to 100mm. The crisscrossing spacing of the horizontal exhaust pipe 500 is 3000mm to 6000mm.

[0027] Furthermore, the horizontal exhaust pipe 500 is laid with the slope of the lightweight aggregate concrete slope adjustment layer 400, with a slope of 1% to 3%.

[0028] This utility model, by setting up horizontal drainage pipes 500 with ventilated holes 501, ensures that all venting structures do not extend beyond the roof layer, achieving unobstructed roof installation and increasing the roof's functionality and application scenarios. The crisscrossing, sloping horizontal vent pipes 500 increase the effective venting range and efficiency of the roof insulation layer 503, and also allow for rapid water vapor discharge, preventing water vapor from affecting the quality of the reinforced concrete protective layer 600 and the waterproof layer 300. Creatively, a one-way valve 502 is installed at the end of the horizontal vent pipe 500 near the roof drainage ditch 701, providing double protection to prevent backflow of water into the insulation layer 503.

[0029] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
