[0002] In the prior art, the roof on the top of the building mainly includes cement roof (i.e. formed by traditional concrete pouring) and steel roof. Among them, the construction efficiency of cement roof is low, and it needs to go through the steps of template installation, steel bar laying and concrete pouring, so not only the construction efficiency is low, but also the cost is high. The steel roof is mainly composed of steel frame and color steel tile, which has the advantages of high construction efficiency and low cost. However, the steel roof has problems such as easy corrosion and aging, short service life, and very unsightly. Utility Model Content

[0003] In view of the above problems, the present application provides a prefabricated roof to solve the technical problems of complex roof construction process, low construction efficiency and short service life.

[0004] To achieve the above-mentioned purpose, the inventor provides a prefabricated roof, which is inclinedly arranged on the top of a building and is formed by splicing two or more autoclaved aerated concrete roof panels;

[0005] The upper surface of the autoclaved aerated concrete roof panel is provided with upwardly protruding hydrophobic protrusions on both sides along the width direction; the hydrophobic protrusions protrude from the upper surface of the autoclaved aerated concrete roof panel in the thickness direction, and the height of the hydrophobic protrusions gradually increases from the middle of the autoclaved aerated concrete roof panel to the edge in the width direction; when two adjacent autoclaved aerated concrete roof panels are spliced ​​along the width direction, the two hydrophobic protrusions are spliced ​​to form a hydrophobic portion with a triangular cross-sectional shape;

[0006] The middle part of the autoclaved aerated concrete roof panel is provided with more than two drainage grooves along the length direction.

[0007] Furthermore, the angle between the hydrophobic protrusion and the plane where the upper surface of the autoclaved aerated concrete roof panel is located is 15-30 degrees.

[0008] Furthermore, a fixing hook is pre-embedded in the lower surface of the autoclaved aerated concrete roof panel, and the fixing hook protrudes from the lower surface. When two adjacent autoclaved aerated concrete roof panels are spliced, the two adjacent autoclaved aerated concrete roof panels are fixedly connected along the width direction through the fixing hook and the connecting piece.

[0009] Furthermore, the fixing hook is a U-shaped hook, and the opening of the U-shaped hook is buried in the autoclaved aerated concrete roof panel.

[0010] Furthermore, the depth of the drainage groove is 1-3 cm.

[0011] Furthermore, a splicing protrusion is provided on one side of the autoclaved aerated concrete roof panel along the width direction, and a splicing groove matched with the splicing protrusion is provided on the other side. When two adjacent autoclaved aerated concrete roof panels are spliced, the splicing protrusion and the splicing groove are mutually engaged.

[0012] Furthermore, a steel mesh is arranged inside the autoclaved aerated concrete roof panel.

[0013] Furthermore, the prefabricated roof is the roof of a prefabricated mobile house, and the mobile house is used for any one or more of a newsstand, a kiosk, a garbage sorting room, and a testing and sampling room.

[0014] Furthermore, the length of the autoclaved aerated concrete roof panel is greater than or equal to 2 meters, and the width is greater than or equal to 0.5 meters.

[0015] Different from the prior art, the prefabricated roof of the above technical solution is formed by splicing more than two autoclaved aerated concrete roof panels, wherein the autoclaved aerated concrete roof panels are prefabricated in the factory and then transported to the construction site for installation. During installation, the autoclaved aerated concrete roof panels are spliced ​​along the width direction and / or along the length direction, so the roof installation is convenient and the construction efficiency is high. In addition, the splicing sides of the autoclaved aerated concrete roof panels are respectively provided with upwardly protruding hydrophobic protrusions, and a plurality of drainage grooves are provided in the middle, so that rainwater can be diverted to the middle of the autoclaved aerated concrete roof panel and drained through the drainage grooves, which can reduce the infiltration of rainwater from the splicing seam between the two autoclaved aerated concrete roof panels, and has a good waterproof and anti-seepage effect. In addition, autoclaved aerated concrete has the advantages of light weight, heat insulation, and weathering resistance, which can ensure the service life of the prefabricated roof.

[0035] See also Figures 1 to 4 The present embodiment provides a prefabricated roof 20, which is obliquely arranged on the top of the building and is formed by splicing more than two autoclaved aerated concrete roof panels 200.

[0036] like Figure 2 and Figure 3 As shown, the upper surface of the autoclaved aerated concrete roof panel 200 is provided with upwardly protruding hydrophobic protrusions 211 on both sides along the width direction; the hydrophobic protrusions 211 protrude from the upper surface of the autoclaved aerated concrete roof panel 200 in the thickness direction, and the height of the hydrophobic protrusions 211 gradually increases from the middle of the autoclaved aerated concrete roof panel 200 to the edge in the width direction; when two adjacent autoclaved aerated concrete roof panels 200 are spliced ​​along the width direction, the two hydrophobic protrusions 211 are spliced ​​to form a hydrophobic portion with a triangular cross-sectional shape; the middle of the autoclaved aerated concrete roof panel 200 is provided with more than two drainage grooves 212 along the length direction.

[0037] The autoclaved aerated concrete roof panel 200 is a porous concrete product made of cement, lime, slag, sand, fly ash, gas generating agent, bubble stabilizer and regulator as main raw materials, through grinding, metering, mixing and pouring, gas expansion, static stop, cutting, autoclaving and curing, finished product processing and other processes, and has the advantages of light weight, waterproof, heat preservation and heat insulation. The hydrophobic protrusions 211 and drainage grooves 212 are integrally formed with the autoclaved aerated concrete roof panel body 21. In the production of the autoclaved aerated concrete roof panel 200, the autoclaved aerated concrete embryo is cut by a cutting device to form structures such as the hydrophobic protrusions 211 and the drainage grooves 212, and then put into an autoclave for autoclaving, so that the autoclaved aerated concrete embryo is steamed and cured to solidify.

[0038] In some embodiments, the length of the autoclaved aerated concrete roof panel 200 is greater than or equal to 2 meters, and the width is greater than or equal to 0.5 meters. In some embodiments, in order to improve the structural strength of the autoclaved aerated concrete roof panel 200, a steel mesh 22 is provided inside the autoclaved aerated concrete roof panel 200.

[0039] In this embodiment, the assembled roof 20 is formed by splicing two or more autoclaved aerated concrete roof panels 200, wherein the autoclaved aerated concrete roof panels 200 are prefabricated in the factory and then transported to the construction site for installation. During installation, the autoclaved aerated concrete roof panels 200 are spliced ​​along the width direction and / or along the length direction, so the roof installation is convenient and the construction efficiency is high. In addition, the splicing sides of the autoclaved aerated concrete roof panels are respectively provided with upwardly protruding hydrophobic protrusions 211, and a plurality of drainage grooves 212 are provided in the middle, so that rainwater can be guided to the middle of the autoclaved aerated concrete roof panel and drained through the drainage grooves 212, which can reduce the infiltration of rainwater from the splicing seam between the two autoclaved aerated concrete roof panels, and has a good waterproof and anti-seepage effect. In addition, autoclaved aerated concrete has the advantages of light weight, heat insulation, and weathering resistance, which can ensure the service life of the assembled roof.

[0040] In some embodiments, the angle between the hydrophobic protrusion 211 and the plane where the upper surface of the autoclaved aerated concrete roof panel 200 is located is 15-30 degrees. The depth of the drainage groove 212 is 1-3 cm.

[0041] like Figure 3 As shown, in some embodiments, a fixing hook 23 is pre-buried in the lower surface of the autoclaved aerated concrete roof panel 200, and the fixing hook 23 protrudes from the lower surface. When two adjacent autoclaved aerated concrete roof panels 200 are spliced, the two adjacent autoclaved aerated concrete roof panels 200 are fixedly connected along the width direction through the fixing hook 23 and the connecting piece 25. The fixing hook 23 is a U-shaped hook, and the opening of the U-shaped hook is buried in the autoclaved aerated concrete roof panel 200. In other embodiments, the fixing hook 23 can also adopt other shapes.

[0042] When the autoclaved aerated concrete roof panels 200 are spliced, the two autoclaved aerated concrete roof panels 200 are arranged in the width direction, and the two ends of the connecting member 25 are respectively fixedly connected to the fixing hooks 23 on the two autoclaved aerated concrete roof panels 200 using fasteners such as bolts, so that the autoclaved aerated concrete roof panels 200 are fixed together in the width direction.

[0043] like Figure 2 and Figure 3As shown, in some embodiments, a splicing protrusion 213 is provided on one side of the autoclaved aerated concrete roof panel 200 along the width direction, and a splicing groove 214 is provided on the other side to match the splicing protrusion 213. When two adjacent autoclaved aerated concrete roof panels 200 are spliced, the splicing protrusion 213 and the splicing groove 214 are mutually engaged. In this embodiment, the splicing protrusion 213 and the splicing groove 214 can facilitate the alignment of the autoclaved aerated concrete roof panels 200 when splicing, thereby improving the splicing reliability and splicing efficiency.

[0044] like Figure 4 As shown, in some embodiments, the prefabricated roof 20 is the roof of a prefabricated mobile house, and the mobile house is applied to any one or more of a newsstand, a kiosk, a garbage sorting room, and a detection and sampling room.

[0045] The whole-house assembled mobile house includes a main frame, an outer wall 11 and an assembled roof 20.

[0046] The main frame is a steel structure frame, including a plurality of vertically installed columns and a plurality of beams connecting two or more of the columns; the outer wall 11 is arranged on the outer side of the main frame, and is formed by splicing two or more outer wall panels. The outer wall panels are connected to the partition or the main frame through a bolt connection structure; the assembled roof 20 is arranged on the top of the main frame, and is formed by splicing two or more autoclaved aerated concrete roof panels 200.

[0047] In this embodiment, the whole house assembled mobile house can be assembled by factory prefabricated parts, wherein the main frame can be composed of various steel structure parts, schematically, the main frame includes multiple steel structure columns and multiple beams. The steel structure columns are arranged vertically, and the bottom of the steel structure columns is fixed with pre-fixed bolts on the ground. The beam is arranged horizontally, and the middle and upper parts of two adjacent steel structure columns can be fixedly connected by the beam to form a stable main frame. After the main frame is built, the exterior wall panels can be assembled on the main frame to form an exterior wall 11, and the assembled roof 20 on the top of the main frame. And the partition 13 can be assembled inside the main frame to separate the house into different spaces. Door openings and windows can be arranged on the exterior wall 11 of the whole house assembled mobile house 1. The top of the door opening can be provided with a door opening beam made of autoclaved aerated concrete beam.

[0048] The exterior wall 11, the partition 13 and the assembled roof are formed by splicing autoclaved aerated concrete panels, which are prefabricated in a factory and have a three-dimensional decorative pattern or functional structure on the surface. During construction, the steel structure members of the main frame and the exterior wall panels, the partition and the roof panels are transported to the construction site and then directly assembled. Since the surface of the autoclaved aerated concrete panels is provided with a three-dimensional decorative pattern or functional structure, there is no need to apply decorative paint or post decorative materials such as wallpaper after the autoclaved aerated concrete panels are constructed and assembled, which greatly optimizes the construction process of the autoclaved aerated concrete panels and improves the construction efficiency of the autoclaved aerated concrete panels.

[0049] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
