Description

Technical Field

[0001] This utility model relates to the field of thermal insulation duct laying technology, specifically to an auxiliary laying structure for composite thermal insulation ducts. Background Technology

[0002] Insulated air ducts are a common type of ventilation duct used in buildings. Through the design of the insulation materials, the ventilation ducts have good thermal insulation performance to maintain the normal operation of the building's air conditioning system.

[0003] In the existing process of laying insulated air ducts, the integrally formed pipes are usually pre-erected in the space of the building where grouting is to be carried out. After the pipes are laid, they are sealed and connected, and then concrete grouting is carried out. However, during construction backfilling or daily use, the insulated air ducts are easily crushed and deformed, affecting the ventilation cross section and effect. In view of this, we propose an auxiliary laying structure for composite insulated air ducts. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary laying structure for composite thermal insulation air ducts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary laying structure for composite insulated air ducts, comprising a composite air duct and a keel, wherein the composite air duct and the keel are laid on the same horizontal plane, a floor layer is laid on the top of the keel, an inner lining air duct is provided inside the composite air duct, and an outer protective layer is covered on the outer surface of the composite air duct.

[0006] Preferably, the number of inner lining ducts is set to three sets, the three sets of inner lining ducts are distributed in a linear array, and the three sets of inner lining ducts are integrally formed.

[0007] Preferably, the composite duct has a filling layer inside, which is located in the gap between the inner lining duct and the outer protective layer, thereby filling the gap between the inner lining duct and the outer protective layer.

[0008] Preferably, the outer protective layer is configured as a hollow rigid structure.

[0009] Preferably, the number of keels is set to two sets, and the two sets of keels are spaced apart at the bottom of the floor layer, and the composite air duct is set between the two sets of keels.

[0010] Preferably, the composite duct has a flat duct on its side for conveying media that do not require insulation, thereby reducing construction costs.

[0011] Compared with the prior art, this utility model provides an auxiliary laying structure for composite thermal insulation air ducts, which has the following beneficial effects: 1. The auxiliary laying structure of this composite insulated air duct, through the reinforced structural design of the outer protective layer and the combination of the rigid insulation core layer inside the composite air duct, forms a "composite beam" effect, which can directly bear the load during construction and use, is not easy to deform, and improves the overall safety and service life of the structure.

[0012] 2. The composite insulated air duct uses an auxiliary laying structure. Through the integrated rigid insulation layer design, the composite air duct can be installed continuously without interruption. In addition, its own thermal conductivity is low, the insulation effect is long-lasting and stable, reducing heat loss, effectively saving energy and preventing condensation.

[0013] 3. The composite insulated air duct uses an auxiliary laying structure. The composite air duct is set as a prefabricated integrated component. No secondary insulation is required on site during the assembly process. In addition, it adopts quick connection methods such as socket, which greatly shortens the construction period and improves the laying efficiency of the composite air duct.

[0014] 4. The composite insulated air duct uses an auxiliary laying structure. The overall robust outer protective layer of the composite air duct can effectively protect the internal insulation material from moisture and physical damage, with good durability, high reliability, and strong applicability.

[0017] like Figures 1-3 As shown, this utility model provides a technical solution: an auxiliary laying structure for composite insulated air ducts, including a composite air duct 1 and a keel 3. The composite air duct 1 and the keel 3 are laid on the same horizontal plane. A floor layer 4 is laid on the top of the keel 3. An inner lining air duct 11 is provided inside the composite air duct 1. The outer surface of the composite air duct 1 is covered with an outer protective layer 12.

[0018] The composite duct 1 has an internal filling layer located in the gap between the inner lining duct 11 and the outer protective layer 12, thereby filling the gap between the inner lining duct 11 and the outer protective layer 12. The filling material in the filling layer is a rigid insulation core, which is tightly bonded to the inner wall of the outer protective layer 12. High-density rigid polyurethane foam, extruded polystyrene board, EPP insulation board or phenolic foam are used to provide insulation and also help enhance the overall structural strength.

[0019] Specifically, there are three sets of inner lining ducts 11, which are arranged in a linear array and are integrally formed. The inner lining ducts 11 are attached to the inner surface of the insulation core layer and are made of PVC, ABS, PP or galvanized metal sheet to form a smooth inner wall of the air duct to reduce air resistance.

[0020] Meanwhile, the outer protective layer 12 is set as a hollow rigid structure. The outer protective layer 12 is made of galvanized steel plate, aluminum plate or metal mesh plate, and mainly plays a structural support and protection role. The pressure on the upper part of the outer protective layer 12 is effectively dispersed to both sides, which greatly improves the compressive bearing capacity and prevents the air duct from being crushed.

[0021] There are two sets of keel 3, and the two sets of keel 3 are spaced apart at the bottom of the floor layer 4. The composite air duct 1 is set between the two sets of keel 3. The side of the composite air duct 1 is provided with a flat air duct 2 for conveying media that do not require insulation, so as to reduce construction costs.

[0022] It is worth noting that the composite duct 1 sections are connected by socket or flange. At the socket interface, the insulation core filling layer inside the composite duct 1 is designed in a stepped shape to ensure that the insulation layer is continuous and seamless after the two sections of composite duct 1 are connected, effectively preventing "cold bridge" and heat loss.

[0023] During the actual installation, several keels 3 are first laid in an alternating pattern on the floor slab, ensuring sufficient installation gaps between adjacent sets of keels 3. Then, the composite air duct 1 is laid on the floor slab base. Next, flat air ducts 2 are laid on the floor slab base on the side of the composite air duct 1, keeping the flat air ducts 2 parallel to the composite air duct 1, so that the keels 3, flat air ducts 2, and the outer area of ​​the composite air duct 1 form an open layer. Then, the open area on the composite air duct 1 and flat air ducts 2 is filled with material, such as lightweight concrete, mortar, or fine stone concrete. Finally, the floor layer 4 is laid on top of the processing layer to complete the installation of the composite insulated air duct.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
