[0023] like Figure 1-Figure 2 As shown, the utility model is an outdoor planting roof building structure of a comprehensive office building in cold regions, comprising: a gutter 10 arranged on the roof, rainwater pipes are arranged at intervals at the bottom of the gutter 10, Figure 2 The direction of the middle arrow is the direction in which rainwater gathers toward the rainwater pipe. Structural layers 9 are arranged on both sides of the gutter 10, and an insulation layer 8 is arranged on the top of the structural layer 9. A leveling layer 7 is arranged on the top of the insulation layer 8. A waterproof layer 6 is arranged on the top of the leveling layer 7. A waterproof protective layer 5 is arranged on the top of the waterproof layer 6. A drainage layer 4 is arranged on the top of the waterproof protective layer 5. A soil barrier layer 3 is arranged on the top of the drainage layer 4. A filter layer 2 is arranged on the top of the soil barrier layer 3. A planting soil layer 1 is arranged on the top of the filter layer 2.

[0024] Specifically, concrete dividing strips 16 are arranged on both sides of the gutter 10.

[0025] Among them, an inner lining 11 is arranged inside the gutter 10, a drain outlet 12 is arranged at the lower part of the inner lining 11 and connected to the rainwater pipe, a boss 13 is arranged on the side wall of the gutter 10, a cover frame 15 is arranged on the upper part of the boss 13, a gutter cover 14 is arranged on the top of the cover frame 15, and the gutter cover 14 is at the same height as the concrete dividing strip 16.

[0026] The specific construction method of this utility model:

[0027] (1) During the drawing review stage, the 3% slope leveling layer and longitudinal gutter were optimized and integrated into the main structure in combination with the use function of the podium roof. The roof structure was improved and φ100 rainwater pipe holes were reserved with φ110 PVC pipes at intervals of 2m.

[0028] (2) Use 70 mm thick extruded polystyrene boards as the roof insulation layer 8. The boards are laid tightly, leveled, cushioned, and the joints are densely caulked.

[0029] (3) The cement mortar is laid with a thickness of 25 mm and compacted and leveled. Before final setting, it is smoothed, polished and moisturized for a second time to form a leveling layer 7.

[0030] (4) The roof waterproofing layer 6 is constructed with 4+4mm thick root penetration resistant modified asphalt waterproofing membrane.

[0031] (5) 80mm thick C20 fine stone concrete is used as the waterproof protective layer 5, with φ4@250×250 bidirectional single-layer steel wire mesh inside, which has a good control effect on the fine cracks generated in the concrete. At the same time, the waterproof protective layer 5 also takes into account the root penetration resistance. Before the initial setting of the concrete, a horizontal drainage groove is pressed out on the concrete surface with φ50pvc semicircular pipes with a spacing of 300mm.

[0032] (6) The setting of drainage layer 4 takes into account that the thickness of the roof planting soil layer in cold areas does not meet the requirements of the frozen soil depth, and the freezing and thawing of the soil body will cause harm to the structure and plants. In order to ensure the benign storage and drainage function of the planting roof, HDPE storage and drainage board is used. This type of drainage board has the advantages of waterproof and heat insulation, water conduction and storage, high flexibility and compressive strength, good root puncture resistance, high stability and strong corrosion resistance, and simple construction.

[0033] (7) Lay a layer of polyester fiber non-woven fabric soil insulation layer 3.

[0034] (8) A filter layer 2 and a planting soil layer 1 are laid on the upper part.

[0035] (9) Concrete dividing strips 16 are set, and the bottom of the concrete dividing strips 16 is buried in each layer, dividing the whole area into several small areas, and the soil is separated and fixed. Trees are planted in each area, and semi-buried steel supports are made around the trees, and the bottom of the support rods are against the concrete dividing strips 16. Except for the location where the trees are planted, the rest is greened with vegetation.

[0036] (10) Install a rear embedded plate on the top of the gutter, weld the cover frame 15, and lay a stainless steel gutter cover 14 on the top. The gutter cover 14 is the same width as the gutter and the same height as the top of the concrete dividing strip 16. It serves as a pedestrian passage on the planting roof.

[0037] The above embodiments are only preferred embodiments of the present invention. The above descriptions do not limit the protection scope of the present invention in turn. The above descriptions are exemplary and not exhaustive. Therefore, any equivalent changes made according to the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
