Description

Technical Field

[0001] This utility model relates to the field of building insulation technology, and in particular to a roof insulation structure. Background Technology

[0002] Roof insulation structures are an important component of building roof systems. Their purpose is to reduce indoor heat loss to the outside through the roof or to prevent outside heat from entering the room, thereby achieving energy conservation and improving indoor thermal comfort.

[0003] Currently, to ensure the roof insulation effect, thick insulation boards are usually laid. However, during long-term use, due to temperature changes and other reasons, moisture may enter the insulation board. The air bubbles inside will be filled with moisture, increasing the thermal conductivity, resulting in poor insulation effect and causing the insulation board to become damp and damaged.

[0004] To address the aforementioned problems, this utility model document proposes a roof insulation structure. Utility Model Content

[0005] This utility model provides a roof insulation structure that solves the problem that in the prior art, during long-term use of insulation boards, moisture may enter the interior of the insulation board due to temperature changes, the air bubbles inside the board will be filled with moisture, the thermal conductivity will increase, resulting in poor insulation effect and damage to the insulation board due to moisture.

[0006] This utility model provides the following technical solution:

[0007] A roof insulation structure, comprising:

[0008] The first waterproof layer, on top of which an insulation layer, a steel mesh layer, a fine stone pad layer, and a second waterproof layer are laid and poured in sequence.

[0009] The dehumidification component, located inside the insulation layer, is used to remove moisture from the insulation layer to prevent the insulation effect from deteriorating and to avoid damage from moisture.

[0010] In one possible design, the dehumidification assembly includes a grid-shaped dehumidification pipe embedded in the insulation layer. The grid-shaped dehumidification pipe has multiple vent holes evenly spaced along its body. A collecting pipe is connected to the center of the grid-shaped dehumidification pipe, and the top of the collecting pipe extends to the outside of the second waterproof layer and is connected to a U-shaped discharge pipe.

[0011] In one possible design, the openings at both ends of the U-shaped drain pipe are positioned downwards to prevent rainwater from entering.

[0012] In one possible design, the first waterproof layer is made of polypropylene fabric.

[0013] In one possible design, the insulation layer is made of extruded polystyrene foam board.

[0014] In one possible design, the second waterproof layer is made of SBS modified bitumen waterproof membrane.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] During construction, first determine the roof size and shape, and prepare the necessary materials, including polypropylene cloth (for the first waterproof layer), extruded polystyrene foam board (for the insulation layer), steel mesh, fine stone concrete (for the fine stone subbase), SBS modified bitumen waterproof membrane (for the second waterproof layer), grid-shaped drainage pipes, collection pipes, and U-shaped drainage pipes, etc. Check whether the roof base layer is flat, dry, and free of oil stains and debris to ensure that the base layer quality meets the construction requirements;

[0018] Next, polypropylene fabric is laid on the roof base layer, ensuring the surface is flat, wrinkle-free, and free of hollow areas. It is then secured with specialized adhesive or nails, and the fabric is overlapped to ensure the overlap width meets specifications. The overlaps are then sealed with sealant. Following this, extruded polystyrene foam board is laid on the first waterproof layer, ensuring the surface is flat, gap-free, and free of hollow areas. According to design requirements, a grid-shaped desiccant pipe is embedded within the insulation layer, ensuring multiple vents are evenly spaced along the pipe. The center of the grid-shaped desiccant pipe is connected to the collection pipe, ensuring a secure and leak-free connection. Finally, a steel mesh is laid on the insulation layer, ensuring the mesh surface is flat and free of hollow areas. To prevent warping and breakage, fix the steel mesh to the insulation layer using nails or special clamps, ensuring a tight bond between the steel mesh and the insulation layer. Next, pour fine aggregate concrete on the steel mesh to form a fine aggregate cushion layer. Use a trowel to smooth the fine aggregate cushion layer, ensuring a flat surface without cracks or hollow areas. Then, lay SBS modified bitumen waterproof membrane on the fine aggregate cushion layer, ensuring the membrane surface is flat, without wrinkles or hollow areas, and overlap the membrane to ensure the overlap width meets the specifications. Seal the overlap area with sealant. Finally, connect the top of the collection pipe to a U-shaped drain pipe, ensuring that both ends of the U-shaped drain pipe face downwards to prevent rainwater from entering.

[0019] This utility model has the following beneficial effects:

[0020] This invention effectively removes moisture from the insulation layer by setting up dehumidification components such as a grid-shaped dehumidification pipe and a collection pipe, thus avoiding problems such as poor insulation performance and damage from moisture, and improving the stability and durability of the roof.

[0021] This invention effectively improves the thermal insulation performance of the roof by using extruded polystyrene foam board as the insulation layer material, reduces heat transfer, and lowers energy consumption. By setting two waterproof layers (polypropylene cloth and SBS modified bitumen waterproof membrane), the waterproof performance of the roof is effectively enhanced, preventing moisture from penetrating into the building structure and extending the building's service life.

[0022] This utility model has the advantages of simple structure, convenient construction, good thermal insulation effect and strong waterproof performance, and is suitable for the thermal insulation and waterproofing needs of various building roofs. Attached Figure Description
