The specific structure and features of this utility model are illustrated below by way of example and should not constitute any limitation on this utility model. Furthermore, any technical feature mentioned below (including implicit or disclosed features), as well as any technical feature directly shown or implied in the figures, can be arbitrarily combined or deleted among these technical features to form more other embodiments that may not be directly or indirectly mentioned in this utility model. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0021] like Figure 1 As shown, the modular building roof waterproof structure of this embodiment includes a roof module 10, a splicing module 30, and a drainage pipe 50. The splicing module 30 is U-shaped and surrounds the roof module 10, forming an eave. A U-shaped water collection trough 70 is provided between the roof module 10 and the splicing module 30, and the water collection trough 70 is connected to the drainage pipe 50. Rainwater and other accumulated water collected by the roof module 10 flows down to the water collection trough 70. One end of the drainage pipe 50 is connected to the water collection trough 70, and the other end leads the water to the ground. A filter screen 72 is laid on the water collection trough 70 to remove debris and garbage, preventing clogging of the drainage pipe 50.
[0022] The roof module 10 includes multiple module units, wherein a drainage joint 15 and a thermal expansion and contraction joint 17 are left between two adjacent module units, and the drainage joint 15 is filled with a sealing waterproof strip 19.
[0023] Specifically, the two adjacent module units are the first module unit and the second module unit, respectively.
[0024] The first module unit includes a first top surface 112, a square profile 114, and a first L-shaped profile 116. The square profile 114 is connected to the first top surface 112 with one side of its side fitting against the lower surface of the first top surface 112. One side of the first L-shaped profile 116 is connected to one bottom side of the square profile 114, and the other side of the first L-shaped profile 116 is suspended, so that a U-shaped groove opening towards the first top surface 112 is formed between the first L-shaped profile 116 and the square profile 114.
[0025] The second module unit comprises a second top surface 123 and a second L-shaped profile 125 and a second I-shaped profile 127, the second L-shaped profile 125 and the second I-shaped profile 127 are connected to the lower surface of the second top surface 123 respectively, and the second top surface 123, the second L-shaped profile 125 and the second I-shaped profile 127 form a frame with a missing corner.
[0026] The first top surface 112 of the first module unit and the second top surface 123 of the second module unit are butted and form a certain height inclination. The I-shaped profile 127 extends into the U-shaped groove, and the I-shaped profile 127 is attached to the side edge of the second L-shaped profile 125, thereby forming a drainage gap 15 between the two adjacent module units, the drainage gap 15 is filled with a sealing waterproof rubber strip 19, and the upper surface of the sealing waterproof rubber strip 19 is U-shaped, which is convenient for water collection and drainage. The second L-shaped profile 125 and the first L-shaped profile 116 leave a thermal expansion and contraction gap 17. When the roof module 10 is heated and expanded, the first module unit and the second module unit are pressed towards each other, and the thermal expansion and contraction gap 17 is narrowed to buffer the deformation of the first module unit and the second module unit. When the roof module 10 is cooled and shrinks, the first module unit and the second module unit are stretched away from each other, and the thermal expansion and contraction gap 17 is widened to buffer the deformation of the first module unit and the second module unit.
[0027] In the embodiment, the drainage gap 15 is transversely arranged, and the drainage gap 15 is longitudinally arranged between the two adjacent roof modules 10, the drainage gap 15 is communicated with the drainage gap, and the drainage gap is communicated with the water collecting groove 70. The water flows from the drainage gap 15 to the drainage gap, and then flows to the water collecting groove 70, thereby quickly draining water.
[0028] The spliced module 30 is used as a roof eave, and a backflow prevention drip line 34 is arranged around the lower surface of the spliced module 30. The backflow prevention drip line 34 is arranged at the outermost side of the lower surface of the spliced module 30 and is the lowest point of the lower surface of the spliced module 30. When the rainwater flows along the spliced module 30 to the lower surface of the spliced module 30, if the backflow prevention drip line 34 is not arranged, part of the rainwater will flow inward along the lower surface of the spliced module 30 and wet the wall or the house. However, when the backflow prevention drip line 34 is arranged, the rainwater will stop at the backflow prevention drip line 34, gather on the backflow prevention drip line 34 and drip, and will not wet the wall or the house.
[0029] The waterproof structure of the modular building roof in the embodiment has excellent waterproof performance, avoids roof leakage, has excellent thermal expansion and contraction resistance, can adapt to temperature changes without cracking, is convenient for assembly and disassembly of the modular building, and is simple to construct and install.
[0030] The above implementation is only the preferred implementation of the present application, and cannot be used to limit the scope of the present application. For those skilled in the art, it can be understood that the embodiments can be changed, modified, replaced and modified in various ways without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
