Description

Technical Field

[0001] The utility model relates to the technical field of roofs, in particular to a support-free prefabricated roof. Background Art

[0002] A roof is the top of a building, used to shade the interior space of the building and provide protection from rain, snow, and sun. It is usually made of a variety of materials. The design and material selection of a roof depend on factors such as the function of the building, its geographical location, climatic conditions, cost, and architectural style. Roofs can be flat or pitched, and can also be designed in complex geometric shapes. Prefabricated roofing is a construction method in which roof components (such as trusses, beams, panels, and insulation materials, etc.) are prefabricated in a factory and then transported to the construction site for assembly.

[0003] For example, the environmentally friendly roof prefabricated parts with heat insulation function having the prior art publication number CN103184780A are directly produced on the ground and then laid on the load-bearing wall. The manufacturing process is simple and the construction cost is reduced. The construction speed is fast: the original cast-in-place construction on the roof required a construction period of more than one month, but now it only takes one day to complete. The environmental protection effect is significant: the prefabricated parts of the present invention can achieve the purpose of heat insulation and energy saving.

[0004] However, the above-mentioned prior art still has the following problems when in use: a plurality of concrete modules are combined to form a roof, but workers are required to use lifting equipment to lift the plurality of concrete modules to the top of the roof for installation, which also takes a lot of time, and it also takes a lot of time to hang tiles on the concrete modules, which leads to low roof installation efficiency. Based on this, the utility model provides a prefabricated roof with higher installation efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a support-free prefabricated roof, which is composed of a roof frame assembly and a roofing assembly, so that the workers can directly lift and install the roof after assembling it on the ground. The modular structure is convenient for transportation and rapid assembly of the roof, and the construction is convenient, thereby reducing the construction cost. In addition, multiple waterproof panels stacked in sequence can be beneficial to the drainage of the roof, thereby solving the problems arising from the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a support-free prefabricated roof, including a roof frame assembly and a roofing assembly, the roof frame assembly includes four connected roof base plates, a positioning plate for installing the roofing assembly is fixedly provided on the top of each roof base plate, a plurality of support plates are fixedly provided between two roof base plates symmetrically distributed front and back, the roofing assembly includes a plurality of concrete modules, each concrete module cross-section is arranged to be inclined, a plurality of concrete modules are arranged between a plurality of positioning plates, and a plurality of concrete modules are fitted together, a plurality of uniformly distributed waterproof boards are provided on the plurality of positioning plates, a slot is provided on one side of each waterproof board, and a plug block is fixedly provided on the other side of each waterproof board, the plug block is plugged into the slot to improve the connection firmness between the plurality of waterproof boards.

[0007] In a preferred embodiment, two insulation boards distributed vertically are fixedly penetrated inside each concrete module. Specifically, the insulation board is an important building material. The insulation board can not only improve the energy efficiency of the concrete module, but also provide shockproof, heat-insulating, sound-insulating and waterproof functions, thereby improving the thermal insulation of the concrete module.

[0008] In a preferred embodiment, a plurality of waterproof grooves are provided on the top surface of each waterproof board to guide the flow of rainwater so that the rainwater falls quickly from the roof and avoids the accumulation of rainwater.

[0009] In a preferred embodiment, the plurality of waterproof panels and the plurality of positioning panels are fixed by a plurality of first expansion bolts, so that it is convenient for the staff to disassemble and install the waterproof panels and to inspect and replace the waterproof panels.

[0010] In a preferred embodiment, the multiple concrete modules and the multiple support plates are fixed by multiple second expansion bolts, which can facilitate the workers to disassemble and assemble the concrete modules and facilitate the later disassembly of the concrete modules for replacement.

[0011] In a preferred embodiment, multiple roof base plates and multiple support plates and multiple roof base plates are fixed by multiple third expansion bolts, which facilitates the assembly of roof base plates and support plates, thereby improving the stability of the entire roof frame assembly.

[0012] In a preferred embodiment, two lifting rings are fixedly provided on the outer walls of the two roof bottom plates. When the roof is actually installed, the roof bottom plates are lifted by lifting equipment to hook the lifting rings and install the roof.

[0013] Technical effects and advantages of the utility model:

[0014] The utility model forms a roof through a roof frame component and a roofing component, so that after the workers assemble the roof on the ground, they can directly lift it for installation.
