Description

Technical Field

[0001] This utility model relates to an inverted roof anti-cracking protective layer structure, belonging to the field of building engineering. Background Technology

[0002] Roofing is an important part of building construction, and its construction quality directly affects the building's functionality. Roof structures are divided into inverted roofs and upright roofs. Inverted roofs are also known as inverted insulated roofs.

[0003] An inverted roof is a roof structure in which the waterproof layer is placed below the insulation layer. Its main advantage is that it protects the waterproof layer from the effects of the external environment and extends its service life. However, existing inverted roofs rely solely on the waterproof layer for crack resistance and lack the synergistic effect of composite materials, which may lead to cracking and other problems during long-term use, affecting their waterproof performance and overall structural stability. To address these issues, we provide an inverted roof crack-resistant protective layer structure. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an inverted roof crack-resistant protective layer structure, the specific technical solution of which is as follows:

[0005] An inverted roof crack-resistant protective layer structure includes a base layer, a protective structural layer on the upper surface of the base layer, a waterproof layer, a crack-resistant layer on the upper surface of the waterproof layer, a thermal insulation layer on the upper surface of the crack-resistant layer, a protective layer on the upper surface of the thermal insulation layer, a drainage layer on the upper surface of the protective layer, and a drainage board on the upper surface of the drainage layer.

[0006] Preferably, the waterproof layer comprises a waterproof membrane located on the upper surface of the substrate, and the crack-resistant layer comprises a polymer-modified mortar located on the upper surface of the waterproof membrane.

[0007] Preferably, the insulation layer includes an insulation foam board, which is located on the upper surface of the polymer-modified mortar.

[0008] Preferably, the protective layer comprises fine aggregate concrete, which is located on the upper surface of the thermal insulation foam board.

[0009] Preferably, the drainage layer includes a pebble layer located on the upper surface of the fine aggregate concrete, and the upper surface of the drainage board has multiple drainage grooves.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This inverted roof anti-cracking protective layer structure, by laying an anti-cracking layer on the upper surface of the waterproof layer, can improve the flexibility and adhesion of the waterproof layer through the polymer-modified mortar in the anti-cracking layer, thereby enhancing the crack resistance of the waterproof layer. In addition, a protective layer is laid on the upper surface of the insulation layer to prevent the insulation layer from being damaged by mechanical force and ultraviolet rays. Therefore, through the combined effect of multiple materials, the problem of easy cracking of traditional inverted roofs is solved. Attached Figure Description

[0024] In this inverted roof crack-resistant protective layer structure, the roof base layer 1 is first cleaned and repaired by workers to ensure that the base layer 1 is flat, dry, and free of oil and dust. Then, a waterproof layer 8 is laid on the upper surface of the base layer 1, and a crack-resistant layer 13 is laid on the upper surface of the waterproof layer 8. Then, an insulation layer 6 is laid on the upper surface of the crack-resistant layer 13, and a protective layer 7 is laid on the upper surface of the insulation layer 6. Finally, a drainage layer 5 is laid on the upper surface of the protective layer 7, and a drainage board 4 is laid on the upper surface of the drainage layer 5 so that water can be discharged through the drainage grooves 10 opened on the upper surface of the drainage board 4.
