DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Figure 1-2

[0019] Embodiment

[0020] Figure 1 Please refer to , the present utility model provides the following technical solutions: A waterproof structure for a building balcony, including a floor slab 1, a wall 2, a balcony wall 3, a slope-forming layer 4, a leveling layer 5, a cement adhesive 6, a polypropylene fiber waterproof cloth 7, a waterproof protective layer 8, and a cement layer 9. The cement adhesive 6 is applied on the upper surface of the leveling layer 5, the polypropylene fiber waterproof cloth 7 is pasted on the cement adhesive 6, and the waterproof protective layer 8 is arranged on the outer surface of the polypropylene fiber waterproof cloth 7.

[0021] Since the above-mentioned cement adhesive 6 has relatively high hardness and stability, using the cement adhesive 6 for caulking can repair the gaps on the sun deck and connect the floor slab 1 and the polypropylene waterproof cloth 7 together at the same time.

[0022] Please refer to Figure 1 and Figure 2 , the waterproof protective layer 8 includes a first waterproof coating 801 and a second waterproof coating 802. The second waterproof coating 802 is applied on the outer surface of the first waterproof coating 801, and the first waterproof coating 801 is applied on the outer surface of the polypropylene waterproof cloth 7.

[0023] Both the first waterproof coating 801 and the second waterproof coating 802 are formed by brushing with polyurethane waterproof coating.

[0024] A slope-forming layer 4 is laid below the leveling layer 5, and the slope-forming layer 4 is laid on the upper surface of the floor slab 1.

[0025] The side of the floor slab 1 is connected to a wall 2, and the edge at the upper end of the floor slab 1 is connected to a sun deck wall 3.

[0026] The outer walls of the wall 2 and the sun deck wall 3 are coated with a cement layer 9.

[0027] By providing the polypropylene waterproof cloth 7, since the polypropylene waterproof cloth 7 is a polymer composite material, while having good waterproof performance, it can maintain stable performance under various environmental conditions, is not easily corroded or damaged, and at the same time the polypropylene waterproof cloth is light and soft, which is convenient for construction.

[0028] The waterproof protective layer 8 formed by brushing on the outer surface of the polypropylene waterproof cloth 7 can further improve the waterproof effect of the sun deck, so as to achieve a good waterproof effect under the condition of increasing the original structural load.

[0029] The working principle and usage process of the present utility model: During the repair of the sun deck, the original structure of the sun deck, namely the floor slab, the leveling layer, and the slope-forming layer, is retained, the felt and other waterproof materials on the surface layer of the sun deck are cleaned, and the surface of the sun deck is cleaned. After the surface cleaning of the sun deck is completed, a polypropylene waterproof cloth is pasted on the surface of the sun deck with cement adhesive without leveling, and then a first waterproof coating 801 is brushed on the surface of the polypropylene waterproof cloth. After the first waterproof coating 801 is dried, a second waterproof coating 802 is brushed. The first waterproof coating 801 and the second waterproof coating 802 form an elastic waterproof protective layer, which has a good waterproof effect. For the sun deck where there is a hidden danger of rainwater backflow between the indoors and outdoors locally, a threshold can be added to prevent rainwater backflow.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
