[0015] To further optimize the technical solution, at least two pieces of the first waterproof membrane are laid, and two adjacent pieces of the first waterproof membrane are overlapped and laid to form a seam between the two pieces. The width of the seam is 100mm on both the long and short sides, and the positions of the transverse overlap seams of the two adjacent pieces of the first waterproof membrane are staggered by ≥500mm.

[0016] To further optimize the technical solution, the thermal insulation and waterproof screed plate is an extruded polystyrene thermal insulation and waterproof screed plate, and the surface of the thermal insulation and waterproof screed plate is covered with a glass fiber mesh and a high molecular polymer mortar coating.

[0017] To further optimize the technical solution, the second waterproof roll is provided with at least two pieces, the long sides of two adjacent second waterproof rolls are overlapped, the short sides of two adjacent second waterproof rolls are butt-jointed and covered with a fixed homogeneous roll on top.

[0022] Further optimizing the technical solution, the hook structure includes:

[0023] Hook bolts, which pass through the autoclaved aerated concrete floor slab and are hooked to the main structure;

[0024] A nut is connected to one end of a hook bolt passing through the autoclaved aerated concrete floor slab.

[0025] To further optimize the technical solution, at least two autoclaved aerated concrete floor slabs are provided, and the two adjacent autoclaved aerated concrete floor slabs are snap-fitted with each other; a groove is provided at the top of the autoclaved aerated concrete floor slab, and one end of the nut and hook bolt extending out of the autoclaved aerated concrete floor slab is accommodated in the groove.

[0026] The technical solution of this utility model has the following advantages:

[0027] 1. The utility model provides a waterproof structure that utilizes the water resistance and adhesion of the rubber waterproof coating layer to effectively bond the waterproof membrane to the upper surface of the autoclaved aerated concrete floor slab, and the bonding is firm without bubbling or falling off.

[0028] 2. This utility model provides a waterproof structure with a first waterproof coating layer of a high-strength water-based rubber asphalt waterproof coating. This high-strength water-based rubber asphalt waterproof coating serves to bond the autoclaved aerated concrete slab to the asphalt membrane.

Two opposite side walls of the autoclaved aerated concrete floor slabs are provided with protrusions and recesses, and the two adjacent autoclaved aerated concrete floor slabs are clamped together by the cooperation of the protrusions and recesses.

[0039] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that the present invention illustrates the roof structure of the present invention by hooking and positioning the autoclaved aerated concrete floor slab on the main structure, which is only a preferred embodiment and does not limit the scope of protection of the roof structure.

[0040] It should be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, the singular forms "a," "an," and "including" may also be intended to include the plural forms. The terms "comprising," "including," and "having" are inclusive and, therefore, specify the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0041] Although the terms first, second, etc. may be used herein to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply a sequence or order when used herein. In addition, in the description of the present invention, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0042] For ease of description, spatial relative terms can be used in the text to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "front", "back", "center", "inside", "longitudinal", "lateral", "side", "vertical", "outside", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation other than the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will then be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The mechanism can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0043] Autoclaved aerated concrete floors are prone to water seepage, and the surface is damp, making it impossible to lay waterproof membranes. The surface is also prone to dust falling off, which affects the adhesion of the waterproof membranes. Ordinary waterproof coatings do not have sufficient adhesion.

[0044] Based on this, the utility model designs a waterproof structure, which utilizes the water resistance and adhesion of the rubber waterproof coating layer to effectively bond the waterproof membrane to the upper surface of the autoclaved aerated concrete floor slab, and the bonding is firm.

[0045] The current conventional autoclaved aerated concrete roofing practice involves inserting joint reinforcement after the autoclaved aerated concrete slabs are installed, pouring premixed cement mortar into the slab seams, filling and smoothing them, and then applying self-leveling screed. This practice connects the roof as a single piece, reducing the autoclaved aerated concrete's ability to deform under external forces. When the main structure shakes, it cannot withstand the force independently and must be subjected to the force as a whole, which can easily damage the autoclaved aerated concrete, affecting its usability and safety.

[0046] Based on this, the utility model designs a roof structure, which hooks and positions the autoclaved aerated concrete floor slab on the main structure, so that the autoclaved aerated concrete floor slab can be offset when subjected to external force, thereby preventing the autoclaved aerated concrete floor slab from being damaged by force.

[0047] Moreover, cement mortar requires curing time, is prone to cracking, is not environmentally friendly, and wastes water resources.

[0048] Based on this, the utility model arranges multiple layers of waterproof membrane on the upper surface of the autoclaved aerated concrete floor slab to achieve the purpose of multi-layer waterproof protection and avoid the occurrence of roof cracks.

[0049] The specific embodiments of the present invention are described in detail below in conjunction with the waterproof structure of the first aspect of the present invention.

[0050] It should be noted that the waterproof structure of the first aspect of the present invention is only a preferred embodiment of the present invention. The waterproof structure of the present invention can adopt the waterproof structure of the first aspect of the present invention or other structures. For the convenience of explanation, the waterproof structure of the first aspect of the present invention will be explained below.

[0051] like Figure 1 As shown, this embodiment discloses a waterproof structure comprising a first waterproof coating layer 3 and at least one layer of waterproof membrane. The first waterproof coating layer 3 is applied to the upper surface of an autoclaved aerated concrete floor slab 2, and the waterproof membrane is applied above the first waterproof coating layer 3. The first waterproof coating layer 3 is a rubber waterproof coating layer. Due to its strong adhesiveness, water resistance, and corrosion resistance, the waterproof membrane can be bonded to the autoclaved aerated concrete floor slab 2.

[0052] The waterproof structure utilizes the water resistance and adhesive properties of the rubber waterproof coating layer to effectively bond the waterproof membrane to the upper surface of the autoclaved aerated concrete floor slab 2. The bond is strong and prevents bubbling or peeling. The rubber waterproof coating layer can be a quick-setting rubber waterproof coating, which cures quickly and is easy to apply.

[0053] In some embodiments, for locations in earthquake zones, with heavy rainfall, or where high bonding strength is required, the rubber waterproof coating layer is a high-strength water-based rubber asphalt waterproof coating layer. This high-strength water-based rubber asphalt waterproof coating serves to bond the autoclaved aerated concrete slab 2 to the asphalt membrane. It can be applied to damp surfaces, dries quickly, and has exceptionally high elongation, effectively resisting cracking and deformation caused by stress in the base layer.

[0054] It should be noted that, for situations not located in an earthquake zone or where the required bonding strength is not high, the rubber waterproof coating layer can be made of ordinary materials.

[0055] In some embodiments, the waterproof structure includes at least one layer of waterproof membrane, which is arranged on the upper surface of the autoclaved aerated concrete floor 2. In this embodiment, the waterproof membrane can be provided with one layer or multiple layers, and the specific arrangement can be determined according to actual conditions.

[0056] In some embodiments, the waterproof membrane is provided with two layers. The upper surface of the autoclaved aerated concrete floor 2 is sequentially provided with a first waterproof coating layer 3, a first waterproof membrane 4, a thermal insulation waterproof screed 5, a second waterproof coating layer 6 and a second waterproof membrane 7.

[0057] In this embodiment, a combination of waterproof coating + waterproof membrane + thermal insulation waterproof leveling plate + waterproof coating + waterproof membrane is applied from bottom to top on the upper surface of the autoclaved aerated concrete floor 2 to achieve multi-layer waterproof protection. The implementation time is short and the waterproof effect is good, which solves the difficulties of traditional structures such as the need for forming and maintenance, easy cracking, and poor environmental protection during wet operations.

[0058] In some embodiments, the first waterproofing membrane 4 is an SBS modified asphalt waterproofing membrane, which offers excellent low-temperature flexibility, high heat resistance, good elongation, and a long service life. The second waterproofing coating layer 6 is a DMSC polyether waterproofing coating layer. DMSC polyether waterproofing coating is a conventional and inexpensive material with strong adhesion to TPO polymer waterproofing membranes and a wide range of applications. The second waterproofing membrane 7 is a TPO polymer waterproofing membrane, which is environmentally friendly, has long-term weather resistance, long-term plasticity, and is easy to install. The thermal insulation waterproofing screed 5 is a thermal insulation waterproofing XPS screed.

[0059] In some embodiments, at least two first waterproof membranes 4 are laid out, and two adjacent first waterproof membranes 4 are overlapped and laid to form a seam between the two. The width of the seam is 100 mm on both the long and short sides, and the positions of the transverse overlap seams of the two adjacent first waterproof membranes 4 are staggered by ≥500 mm.

[0060] In some embodiments, the thermal insulation and waterproof screed 5 is made of extruded polystyrene (EXPS), a cost-effective core material. The surface of the thermal insulation and waterproof screed 5 is covered with a fiberglass mesh and a polymer mortar coating. This provides high strength, low weight, and ease of on-site fabrication and cutting.

[0061] In some embodiments, the second waterproof roll 7 is arranged in at least two pieces, the long sides of the two adjacent second waterproof rolls 7 are overlapped, the short sides of the two adjacent second waterproof rolls 7 are butt-jointed and covered with a fixed homogeneous roll on top, thereby ensuring the sealing between the two second waterproof rolls 7.

[0062] The specific embodiments of the present invention are described in detail below in conjunction with the roof structure of the second aspect of the present invention.

[0063] It should be noted that the roof structure of the second aspect of the present invention is only a preferred embodiment of the present invention. The roof structure of the present invention can adopt the roof structure of the second aspect of the present invention or other structures. For the convenience of explanation, the roof structure of the second aspect of the present invention will be explained below.

[0064] like Figures 2 to 3 As shown, this embodiment discloses a roof structure, including a main structure 1, an autoclaved aerated concrete floor 2 and a waterproof structure.

[0065] The main structure 1 is a steel structure, more specifically, H-shaped steel. The autoclaved aerated concrete floor slab 2 is a prefabricated slab, and at least one autoclaved aerated concrete floor slab 2 is provided. The autoclaved aerated concrete floor slab 2 is hooked to the main structure 1 via a hook structure. A waterproof structure is disposed on the outer surface of the autoclaved aerated concrete floor slab 2, preferably on the upper surface of the autoclaved aerated concrete floor slab 2.

[0066] In the above-mentioned roof structure, since the autoclaved aerated concrete floor 2 is positioned on the main structure by hooking, when the main structure 1 shakes, the autoclaved aerated concrete floor 2 can be displaced, so that the autoclaved aerated concrete floor 2 has the ability to deform when subjected to external force, preventing the autoclaved aerated concrete floor 2 from being damaged due to the inability to deform under external force, thereby improving the service life and safety of the roof structure.

[0067] In some embodiments, the hooking structure includes a hook bolt 8 and a nut 9. The hook bolt 8 passes through the autoclaved aerated concrete floor slab 2 and is hooked to the main structure 1. The nut 9 is connected to one end of the hook bolt 8 passing through the autoclaved aerated concrete floor slab 2.

[0068] In this embodiment, the hook bolt 8 includes a first bolt and a second bolt, which are integrally connected to form an L-shape. The first bolt contacts and hooks with the bottom end of the top plate of the H-shaped steel, while the second bolt passes through the autoclaved aerated concrete floor slab 2 and is connected to a nut 9. Locking the nut 9 secures the autoclaved aerated concrete floor slab 2 to the main structure 1.

[0069] In some embodiments, a groove is formed at the top of the autoclaved aerated concrete floor slab 2 , and the ends of the nut 9 and the hook bolt 8 extending out of the autoclaved aerated concrete floor slab 2 are accommodated in the groove.

[0070] In this embodiment, the grooves provided enable the heights of the nuts 9 and the hook bolts 8 to be lower than the upper surface of the autoclaved aerated concrete floor 2, so that when the waterproof membrane is bonded, the nuts 9 and the hook bolts 8 will not affect the bonding of the waterproof membrane.

[0071] In some embodiments, at least two autoclaved aerated concrete floor slabs 2 are provided. Two opposing side walls of the autoclaved aerated concrete floor slab 2 are provided with protrusions 21 and recesses 22 , and two adjacent autoclaved aerated concrete floor slabs 2 are connected by the engagement of the protrusions 21 and the recesses 22 .

[0072] In this embodiment, two adjacent autoclaved aerated concrete floor slabs 2 are spliced ​​together, and each autoclaved aerated concrete floor slab 2 is hooked to the main structure 1 through a hooking structure, thereby making the connection between each autoclaved aerated concrete floor slab 2 more secure, and each autoclaved aerated concrete floor slab 2 can be displaced when subjected to external force, so that each autoclaved aerated concrete floor slab 2 is not easily damaged when subjected to external force.

[0073] The specific embodiments of the present invention are described in detail below in conjunction with the roof waterproofing construction method according to the third aspect of the present invention.

[0074] It should be noted that the roof waterproofing construction method of the third aspect of the present invention is only a preferred embodiment of the present invention. The roof waterproofing construction method of the present invention can adopt the roof waterproofing construction method of the third aspect of the present invention, or other methods. For the convenience of explanation, the roof waterproofing construction method of the third aspect of the present invention will be explained below.

[0075] This utility model primarily utilizes steel structures and autoclaved aerated concrete floor slabs. Based on this type of prefabricated building, a roof waterproofing construction method is provided. This construction method, centered on prefabrication, involves cleaning the autoclaved aerated concrete roof panels, removing dust and powder from the surface to ensure the autoclaved aerated concrete is dry and undamaged. A combination of waterproof coating, waterproof membrane, thermal insulation and waterproof screed, waterproof coating, and waterproof membrane is applied from bottom to top, achieving multi-layered waterproof protection with a short implementation time and excellent waterproofing effectiveness. This method addresses the difficulties of traditional structures, such as the need for forming and curing, prone to cracking, and poor environmental performance during wet operations.

[0076] A roof waterproofing construction method comprises the following steps:

[0077] S1. Cleaning of autoclaved aerated concrete roof panels: Autoclaved aerated concrete roof panels should be dry, free of damage, dust and oil. Uneven spots and cracks should be filled with polyurethane sealant. Clean and sweep before construction to ensure that the autoclaved aerated concrete floor panels are dry and free of damage.

[0078] S2. Apply high-strength water-based rubber asphalt waterproof coating: Apply the high-strength water-based rubber asphalt waterproof coating to the treated base surface, ensuring that no gaps or exposed areas are left. Once the coating is complete and the surface is dry (generally, not sticky), the waterproofing membrane can be installed.

[0079] S3. Marking and laying the asphalt membrane: On the treated and dried base surface, mark the datum line for laying the membrane according to the width of the selected membrane (100m for both the long and short sides), leaving an overlap dimension. This will allow for the membrane to be laid according to this datum line. Pre-roll the membrane to release stress, then re-roll it for laying. For hot-melt laying, hold a flame heater toward the entire roll to be laid, moving the nozzle back and forth to bake it. Heat evenly, avoiding overheating or burning through the membrane. When the adhesive layer on the bottom of the membrane is glossy black and contains microbubbles (no large bubbles are allowed), roll the membrane for bonding and laying, followed by a person to perform the degassing and compaction process.

[0080] After laying, the roll material should be flat and straight, with the overlap size correct and free of distortion. The overlap width of the roll material should comply with the relevant specifications. The width of the joint is 100mm on both the long and short sides. The horizontal overlap positions of two adjacent roll materials should be staggered by ≥500mm.

[0081] Use a blowtorch to thoroughly bake the asphalt coating on the bottom surface of the upper coil and the upper surface of the lower coil at the overlap. Ensure that the asphalt between the coils at the overlap is densely fused, with molten asphalt overflowing from the edges to form asphalt strips of uniform width. Inspect as you lay the tiles, using a screwdriver to check the joints (pry the welds with a screwdriver to check for any unwelded areas). Repair any inaccurate welds promptly, leaving no hidden dangers. On-site construction workers and quality inspectors must conduct on-site inspections, paying particular attention to correct procedures at the intersection of plan and elevation, corners, and angles.

[0082] S4. Thermal Insulation and Waterproof XPS Screed Installation: After the hot-melt asphalt waterproofing membrane has been inspected and accepted, the thermal insulation and waterproof XPS screed should be installed promptly. The thermal insulation and waterproof XPS screed is made of extruded polystyrene as the core material, covered with a fiberglass mesh and a polymer mortar coating. After leveling the base with specialized adhesive, the thermal insulation and waterproof XPS screed is laid. Edge joints are sealed with mesh cloth and specialized adhesive.

[0083] S5. Laying the TP0 polymer waterproofing membrane: First, lay out the lines. Pre-laying is essential during construction. Arrange the naturally loose membrane according to its contour on the XPS screed base, ensuring it is flat and straight without twisting. The overlap should be 80mm, and the membrane should be appropriately trimmed. After laying and unrolling, allow the membrane to rest for 15-30 minutes to fully release internal stress and prevent wrinkling during welding. Fold the membrane in half, exposing the underside. Use a scraper to evenly apply the DMSC polyether waterproofing coating to the underside of the folded membrane, taking care to avoid accumulation and ensuring a uniform coating. After applying the DMSC polyether waterproofing coating, the TP0 membrane can be laid. Repeat the same process for the other half of the membrane. Overlap the long side of the membrane with an 80mm overlap. The short side of the membrane is butted, and a 150mm wide uniform membrane is used to cover the weld. After laying the membrane, compact the surface with a large roller. After the large surface roll material is laid, U-shaped strips and load distribution ropes are installed around the roof.

[0084] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
