Large slope green roof structure and its construction method

Abstract

The present invention discloses a large-slope planting roof structure and a construction method thereof. The roof anti-slope is designed into high and low sloping slopes with equal intervals, and heat-insulating support blocks are arranged between the high and low sloping slopes to support drainage boards used for planting vegetation. The drainage boards are fixed and tied using anchor rods with waterstops that are pre-buried in the large-slope roof panels. The heat-insulating support blocks filled in the cavities of the honeycomb panels and the accommodating grooves are used for heat insulation and to support the drainage boards and vegetation on the top. The pulling effect of the anchor rods can firmly fix the drainage boards to the large-slope roof panels, so that they will not slide down due to gravity or external forces, thereby ensuring the safety of the roof planting structure. The present invention solves the problem that when greening is laid out on some sloping roofs, the thermal insulation layer, waterproof layer, drainage (storage) layer, and planting soil layer are prone to sliding down, posing a high safety hazard.

Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a large-slope planting roof structure and a construction method thereof. Background Art

[0002] The process of urbanization has created a conflict between the development of extensive urban infrastructure and the use of green space. Green roofs, as a form of greening that doesn't occupy ground, effectively address this conflict. Residential rooftop greening, in particular, can better address the conflict between building and garden landscaping. Cultivating a layer of vegetation above the rooftop insulation and waterproofing expands the green area and enhances the city's green lungs. Green roofs can effectively resolve the conflict between urban infrastructure development and green space, increasing green coverage and improving green visibility. Plants maintain the balance of oxygen and carbon dioxide in the atmosphere, absorb dust and toxic and harmful gases, sterilize, and purify the air.

[0003] Traditional green roofs are roofs that are insulated by covering the waterproofing layer with soil or loose materials such as sawdust and vermiculite, and then planting plants. Planting soil and plants are also applied to the waterproofing layer of building roofs and underground project ceilings to provide waterproofing, thermal insulation, and environmental protection. However, when planting greenery on some sloping roofs (with a slope greater than 20%), the thermal insulation layer, waterproofing layer, drainage (storage) layer, and planting soil layer are prone to sliding, posing a significant safety hazard.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0048] Combine Figure 3 As shown, drainage panels 4 are laid on top of the insulating support blocks 2. These panels 4 are connected to the steeply pitched roof panels 5 via anchor rods. Multiple drainage panels 4 are joined to the tops of the backfill soil 3 in the water storage tanks to form a wavy planting surface a. These panels 4 are used for planting vegetation.

[0049] When planting vegetation, the planting medium is filled into the drainage board. The drainage board is connected to one end of the anchor rod. The other end of the anchor rod is embedded in the steeply sloped roof panel. The other end of the anchor rod is installed with a water stop.

[0050] Continue reading Figure 3 As shown, a limit plate is installed on the top of the high ridge 11 and the low ridge 12. The drainage plate 4 is embedded between the two adjacent limit plates.

[0051] In this embodiment, the limiting plate is an angle steel and is mounted on the top of the high ridge 11 and the low ridge 12 by bolts.

[0052] The present invention provides a construction method for a large-slope planted roof structure, comprising the following steps:

[0053] S1: constructing the steep slope roof panel 5, integrally casting multiple anti-ridge components on the steep slope roof panel 5, and pre-embedding anchor rods in the steep slope roof panel 5.

[0054] S2: Laying a waterproof layer 13 on the steeply sloped roof panels 5 and the multiple anti-slope components.

[0063] The steep slope planting roof structure of the present invention utilizes the roof anti-ridge to be designed into high and low ridges with equal intervals, and heat-insulating support blocks are arranged between the high and low ridges to support the drainage board (such as a honeycomb grid board) used for planting vegetation. The drainage board is tied and fixed using anchor rods with waterstops that are pre-buried in the steep slope roof panel. The heat-insulating support blocks filled in the cavities of the honeycomb panel and the accommodating groove are used for heat insulation and to support the drainage board and vegetation on the top. The end of the anchor rod is provided with a waterstop and is pre-buried in the steep slope roof panel. The waterstop can effectively avoid the leakage of the structure caused by the seepage channel generated by the pre-buried anchor rod. The pulling effect of the anchor rod can firmly fix the drainage board to the steep slope roof panel, so that it will not slide down due to gravity or external force, thereby ensuring the safety of the roof planting structure.
