Description

Technical Field

[0001] The utility model relates to the technical field of slope roof eaves gutters, in particular to a concealed eaves gutter connection structure for a reinforced concrete slope roof. Background Art

[0002] The building roof should have the ability to drain rainwater and its drainage form. In order to drain rainwater from the roof in an orderly manner, a rainwater drainage system should be set up on the roof. Rainwater pipes should be arranged reasonably, and rainwater pipes or drainage ditches with appropriate pipe diameters should be selected according to the designed flow rate. Organized drainage is a drainage method that drains water on the roof in an organized manner to the ground or underground pipes.

[0003] According to the local architectural style, the top floor exterior wall is designed to be set back and the roof is a sloped roof. In a sloped roof building, if the drainage ditch is not continuous, it will increase the difficulty of on-site construction and also affect the shape of the building facade. Therefore, in a sloped roof building, the continuity of the drainage ditch should be ensured as much as possible to better meet the construction requirements and ensure the beauty of the building facade.

[0004] Traditional gutter drainage requires pre-buried water holes on the structural beams, and the workload of pre-buried and installed templates on site is large; the advantages of finished gutter drainage are that it can be factory-produced, reducing the amount of on-site construction, and can be customized as needed to meet the needs of different buildings. However, finished gutter drainage also has some problems. It requires additional installation of fixings, which can easily damage the waterproof layer of the roof, and is inconvenient to construct in some buildings with special shapes, and it will also affect the appearance of the facade. Utility Model Content

[0007] A pitched roof assembly comprises a pitched roof structural beam arranged on the top floor of a building, a pitched roof structural plate arranged on the pitched roof structural beam, and a cantilevered flat plate connected to the pitched roof structural beam; the pitched roof structural plate is arranged obliquely; the cantilevered flat plate is parallel to a horizontal plane, and the plane where the cantilevered flat plate is located is lower than the plane where the pitched roof structural plate is located; the pitched roof structural plate and the cantilevered flat plate are respectively provided with upper roof tiles and lower roof tiles obliquely;

[0008] The eaves gutter assembly comprises a drainage ditch arranged between the slope roof structure plate and the cantilevered flat plate, and a rain downpipe connected to the drainage ditch; the drainage ditch is arranged close to the lowest end of the slope roof structure plate.

[0009] As a further improvement of the utility model, a support column is provided on the cantilevered flat plate; a spacing is left between the support column and the sloping roof structure beam to form a drainage ditch.

[0010] As a further improvement of the utility model, an empty space is formed between the lower roof tile and the supporting column and the cantilevered flat plate; a filler is provided in the empty space to support the lower roof tile.

[0011] As a further improvement of the utility model, the lower roof tiles and the upper roof tiles are located on the same inclined plane.

It should be understood that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] In one embodiment, see Figure 1 The utility model discloses a concealed gutter connection structure for a reinforced concrete slope roof, comprising a building body 1, a roof assembly, and a gutter assembly.

[0019] Among them, the building body 1 includes structural beams, floor slabs and roofs arranged on the structural beams, partition walls are built on the floor slabs, and one of the partition walls on the floor slabs is retreated on the floor slabs to form a balcony; the slope roof assembly includes a slope roof structural beam 2 arranged on the top floor of the building, a slope roof structural plate 3 arranged on the slope roof structural beam 2, and a cantilevered flat plate 4 connected to the slope roof structural beam 2, the slope roof structural plate 3 is inclined, and the cantilevered flat plate 4 is parallel to the horizontal plane; the plane where the cantilevered flat plate 4 is located is lower than the plane where the slope roof structural plate 3 is located; the slope roof structural plate 3 and the cantilevered flat plate 4 are respectively inclinedly provided with upper roof tiles 5 and lower roof tiles 6; the eaves gutter assembly includes a drainage ditch 7 arranged between the slope roof structural plate 3 and the cantilevered flat plate 4, and a rain downpipe 8 connected to the drainage ditch 7, and the drainage ditch 7 is arranged close to the lowest end of the slope roof structural plate 3.

[0020] Furthermore, a support column 9 is provided on the cantilevered flat plate 4 , and a spacing is left between the support column 9 and the sloping roof structure beam 2 to form a drainage ditch 7 .

[0021] Preferably, the support column 9 is a concrete column cast integrally with the cantilevered platform.

[0022] Preferably, the width of the drainage ditch 7 is in the range of 350 mm to 450 mm.

[0023] Preferably, the length of the cantilevered platform is 2200 mm, and a concrete molding structure 10 is provided at one end of the cantilevered platform away from the sloping roof structure beam 2 . The concrete molding structure 10 is cast integrally with the cantilevered platform, and the concrete molding structure 10 is constructed according to the design of the building body 1 .

[0024] Furthermore, an empty space 11 is formed between the lower roof tile 6 , the supporting column 9 and the cantilevered flat plate 4 , and a filler 12 is provided in the empty space 11 to support the lower roof tile 6 .

[0025] Preferably, the filler 12 is backfilled with ceramsite concrete, which supports the lower roof tiles 6 while reducing the weight of the filler 12, effectively reducing the roof load and improving the thermal insulation performance of the roof.

[0026] Furthermore, the lower roof tile 6 and the upper roof tile 5 are located on the same slope.

[0027] Preferably, the slope of the lower roof tile 6 is the same as that of the upper roof tile 5, and one end of the lower roof tile 6 adjacent to the sloping roof structure beam 2 extends beyond the supporting column 9 and is located above the gutter 7, while one end of the upper roof tile 5 adjacent to the supporting column 9 extends beyond the sloping roof structure beam 2 and is located above the gutter 7.

[0029] With regard to the structural cantilever plate, technical optimization is carried out to improve the original cantilevered inclined beam and inclined plate structure into a cantilevered flat plate 4. This optimization not only simplifies the construction steps, but also improves the safety and stability of the structure.

[0030] For the shape of local sloping roofs, lightweight aggregate concrete is used for backfilling. This material has the characteristics of light weight, high strength and good durability. It can effectively reduce the roof load and improve the thermal insulation performance of the roof. During the backfilling process, backfill is carried out directly at the reserved drainage gutter position to ensure smooth connection between the drainage system and the drainage gutter.

[0031] Finally, the drainage system is connected to the drainage facilities along the exterior wall, ensuring smooth drainage of the roof and avoiding the adverse effects of water accumulation on the building.

[0032] The utility model is suitable for slope roof buildings, especially for those occasions where the drainage system is required not to affect the building facade and avoid damage to the roof waterproof layer. Compared with the traditional slope roof drainage ditch 7, it can effectively improve the impact of the drainage system on the facade, so that the drainage facilities are integrated with the architectural style, which not only enhances the aesthetics of the building, but also significantly improves the overall visual effect.

[0033] The concealed inner gutter adopts a unique optimized design, which enables the entire drainage gutter to be continuous. The feature of this design is that there is no need to pre-embed water holes on the structural beams, which significantly reduces the workload of on-site pre-embedding and installation of formwork. It can be cast in one go with the main structure, greatly simplifying the construction steps and improving construction efficiency, while avoiding possible damage to the roof waterproofing layer caused by later installation.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
