Description

Technical Field

[0001] This utility model relates to the field of roof waterproofing technology, specifically to a roof waterproofing protective layer. Background Technology

[0002] The conventional construction process for pouring concrete for the roof waterproofing protective layer typically includes the following steps: First, a non-woven fabric isolation layer is laid on the surface of the waterproofing layer. Then, extruded polyethylene foam board is laid on the non-woven fabric as a buffer layer. Finally, the concrete protective layer is poured directly onto the foam board. After the concrete reaches its final set, construction workers use specialized cutting equipment to cut grooves in the concrete surface. After the grooves are cut, structural adhesive is injected to seal them. However, this traditional construction method has significant quality defects: due to the shrinkage characteristics of concrete and the effects of temperature stress, the protective layer concrete is prone to irregular cracks. At the same time, the adhesion between the structural adhesive at the cuts and the concrete and waterproofing layer is often unsatisfactory, easily forming seepage channels, which may eventually lead to the failure of the roof waterproofing system and roof leakage. These defects not only affect the functionality of the building but also shorten the service life of the roof and increase later maintenance costs. Therefore, based on actual usage, we have improved the above-mentioned existing technology. Utility Model Content

[0003] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0004] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A roof waterproofing protective layer, comprising the roof body; The roof structure has a longitudinal armored seam in the middle of its inner cavity. The top and bottom of the armored seam are filled with flexible extruded polystyrene board, and a sound insulation material layer is installed in the middle of the armored seam. The main body of the roof includes a base layer, an isolation layer on top of the base layer, an insulation layer on top of the isolation layer, a sound insulation layer on top of the insulation layer, a fiberglass mesh layer on top of the sound insulation layer, a crack-resistant mortar base layer on top of the fiberglass mesh layer, a sand-fixing layer on top of the crack-resistant mortar base layer, a concrete layer on top of the sand-fixing layer, and a roof cut on top of the concrete layer corresponding to the armor joint, with a polyurethane waterproof adhesive layer filling the roof cut.

[0006] Furthermore: Extruded polystyrene boards are provided on both the left and right sides of the armor seam, and the extruded polystyrene boards on the left and right sides are arranged vertically and parallel to each other. Sloping plates are provided on the top and bottom of the opposite side of the extruded polystyrene boards.

[0007] Furthermore: the sound insulation material layer is set as a fiber sound-absorbing cotton layer, and the top and bottom of the fiber sound-absorbing cotton layer are both equipped with external panels.

[0008] Furthermore, a waterproof layer is provided between the top of the sound insulation layer and the bottom of the fiberglass mesh layer. The waterproof layer is an elastic epoxy waterproof coating layer.

[0009] Furthermore: the sound insulation layer is set as a sound insulation material board, and the top four sides of the sound insulation material board are provided with grooves, and the grooves are filled with fiber sound-absorbing cotton.

[0010] Furthermore, the top and bottom of the sound insulation layer are reinforced with steel wire.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The roof waterproofing protective layer proposed in this paper aims to effectively control concrete shrinkage cracks and improve roof waterproofing performance. Firstly, an armored joint structure is added during the concrete construction of the roof waterproofing protective layer. Simultaneously, a 1-cm thick high-quality flexible buffer material is embedded inside the armored joint. This dual-protection design significantly absorbs and disperses the internal stress generated by temperature changes and shrinkage deformation in the concrete, thereby effectively preventing the formation and development of cracks. Secondly, addressing the shortcomings of traditional cutting methods, high-performance polyurethane waterproofing adhesive is used instead of ordinary structural adhesive for injection sealing. This material has excellent elastic recovery and long-lasting waterproof sealing performance, not only adapting to minor displacement deformations of the concrete structure but also forming a continuous and dense waterproof barrier, thus significantly improving the overall reliability and durability of the roof waterproofing system. The organic combination of these two technical measures constitutes a complete crack control and waterproofing enhancement system.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0021] Please see Figure 1-2 This utility model provides a technical solution: a roof waterproof protective layer, including a roof body 1; The inner cavity of the main roof 1 is longitudinally provided with an armored joint 2. The top and bottom of the inner cavity of the armored joint 2 are filled with flexible extruded polystyrene board 3. The flexible extruded polystyrene board 3 is a high-quality flexible buffer material. Its placement in the armored joint 2 can effectively reduce cracks caused by concrete stress. The inner cavity of the armored joint 2 is provided with a sound insulation material layer 4. The sound insulation material layer 4 can play a sound insulation role and prevent external noise from passing through and spreading into the room at the armored joint. The roof structure 1 includes a base layer 5, an isolation layer 6 on top of the base layer 5, an insulation layer 7 on top of the isolation layer 6, which provides insulation, a sound insulation layer 8 on top of the insulation layer 7, which reduces noise and minimizes the transmission of external noise into the room, a fiberglass mesh layer 9 on top of the sound insulation layer 8, a crack-resistant mortar base layer 10 on top of the fiberglass mesh layer 9, a sand-fixing layer 11 on top of the crack-resistant mortar base layer 10, and a concrete layer 12 on top of the sand-fixing layer 11. The crack-resistant mortar base layer 10 and the sand-fixing layer 11 effectively improve the surface strength of the concrete layer 12, providing high strength and waterproofing, thus increasing the stability of the concrete layer 12. A roof cut is longitudinally provided on the top of the concrete layer 12 at the location corresponding to the armor joint 2, and a polyurethane waterproof adhesive layer is filled in the roof cut to enhance the waterproofing effect of the roof.

[0022] Preferably, extruded polystyrene (XPS) boards are provided on both the left and right sides of the armor seam 2. The XPS boards on the left and right sides are arranged vertically and parallel to each other. The top and bottom of the opposite sides of the XPS boards are provided with sloping plates. This arrangement can increase the structural strength of the armor seam 2 and make the armor seam 2 less prone to shrinkage and deformation.

[0023] Preferably, the sound insulation material layer 4 is a fiber sound-absorbing cotton layer. The fiber sound-absorbing cotton is easy to use, odorless, waterproof, moisture-proof, breathable, and easy to process. It can also play a good sound insulation role. The top and bottom of the fiber sound-absorbing cotton layer are provided with external plates. The external plates can play a limiting and supporting role, preventing the flexible extruded board 3 from being excessively squeezed into the sound insulation material layer 4. Example 2:

[0024] Reference Figure 1-2This embodiment differs from the first embodiment in that: a waterproof layer is provided between the top of the sound insulation layer 8 and the bottom of the fiberglass mesh layer 9. The waterproof layer is an elastic epoxy waterproof coating layer, which has high acid and alkali resistance and corrosion resistance, good elasticity, can cover cracks and deformations, can be applied to damp substrates, does not foam, delaminate, or crack when exposed to water, has high adhesion, and can firmly bond with common materials such as concrete, metal, and wood. The sound insulation layer 8 is a sound insulation material board, with grooves on all four sides of the top of the sound insulation material board. The grooves are filled with fiber sound-absorbing cotton, which is easy to use, odorless, waterproof, moisture-proof, breathable, and easy to process, and also provides good sound insulation. The top and bottom of the sound insulation layer 8 are reinforced with steel wire reinforcement layers, which strengthen the structural strength of the sound insulation layer 8 and make it less prone to deformation and denting.

[0025] It should be noted that the electrical components of this utility model have already combed the wire harness during operation, so there will be no problem of wire harness tangling.

[0026] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
