Description

Technical Field

[0001] The invention relates to the technical field of green roofs, in particular to a green roof structure of a green building and a construction method. Background Art

[0002] Roof greening is of great significance to increasing urban green space, developing green space for human beings, building garden cities, improving people's living conditions, improving the quality of life, beautifying the urban environment and improving ecological effects.

[0003] At present, green roofs are usually built by directly laying soil after the waterproof structure of the roof is completed, and then planting green plants on the soil. As the plants grow, the roots of the plants will penetrate into the soil. However, if the soil layer is limited, or the boundary between the soil and the roof structure is not completely isolated, the roots may continue to grow outward and break through the soil boundary; especially for some large plants or fast-growing varieties, the expansion of the root system may affect the basic structure of the roof; for example, after the roots enter the basic part of the roof, the following problems may occur:

[0004] Foundation damage: The growth of the root system may cause the waterproof layer or foundation material of the roof to crack or loosen; the continuous expansion of the root system may damage the waterproof layer or foundation, allowing moisture to penetrate into the structural layer of the roof, thereby affecting the safety of the house;

[0005] Cracks: As the roots grow, they may create pressure on the roof foundation. As the roots expand, cracks may form. If the cracks are not repaired in time, they may cause structural problems in the roof foundation and even affect the stability of the entire building.

[0006] At present, most green roofs are planted in the open air, that is, plants are planted directly in the soil of the roof without special covering or protection to cope with environmental changes. This method is easily affected by external climatic conditions, especially in cold climate areas (such as winter in the north) or during thunderstorms, plants will face a series of challenges:

[0007] Impact of cold air: Low temperatures in the north during winter have a significant impact on plants grown outdoors, especially those that are not very cold-resistant. Cold temperatures may damage the root systems of plants, or even cause them to die from freezing. In low-temperature weather, snowstorms or cold waves may cause the leaves or branches of plants to be frozen or even cracked. In addition, cold weather may be accompanied by strong winds, and snowstorms may cause the branches of plants to be broken, affecting their growth.

[0008] Water accumulation problem: During thunderstorms, heavy rain may cause poor drainage of the roof, resulting in excessive water accumulation on the soil surface; excessive water accumulation may cause plant roots to lack oxygen, leading to root rot and affecting plant health; for some plants that are not tolerant to waterlogging, water accumulation is more likely to make them unable to survive. In view of this, in-depth research was conducted on the above-mentioned issues, which led to this case. Summary of the invention

[0023] Preferably, a plurality of the protective frames are connected by a plastic film.

[0024] A construction method for a green roof structure of a green building, comprising the following steps: Step S1: assembling a composite waterproof structure on the ground or at a designated corner of a roof in advance, firstly laying a first waterproof layer on the ground, then laying and applying a second structural net and an adhesive layer on the first waterproof layer, and after applying evenly, finally laying the second waterproof layer on the second structural net, and then waiting for the adhesive layer to solidify, thereby completing the purpose of assembling the composite waterproof structure;

[0025] Step S2: Move the composite waterproof structure to a designated position, apply mortar on the roof body, and then heat the composite waterproof structure again with a torch to soften the internal adhesive layer slightly, so that the composite waterproof structure can be slightly deformed to ensure the fit with the roof body;

[0026] Step S3: After the composite waterproof structure is hardened, the thermal insulation layer and the first structural mesh are laid on the upper end of the composite waterproof structure in sequence;

[0027] Step S4: The staff casts the first concrete protective layer on the first structural mesh and the insulation layer. Before the first concrete protective layer is completely solidified, the anti-cracking mesh and the third waterproof layer are sequentially laid on the first concrete protective layer. Finally, the second concrete protective layer is cast on the third waterproof layer to fully wrap the anti-cracking mesh and the third waterproof layer. Finally, the composite waterproof structure and the protective isolation structure are completely solidified.

[0028] Step S5: hoist the installation box to the top of the roof by hoisting equipment, and fully adjust the position of the installation box according to the greening requirements, then lay a moisture-retaining layer under the planting box, then fill the planting soil into the planting box, and then select suitable green plants to be planted in the planting soil according to the greening requirements and the temperature of the planting area, and support the planting box in the installation box by cooperating with a plurality of support rods and mesh plates;

[0029] Step S6: Then, the water inlet pipe group is connected to the water source pipe to ensure the stability of water supply for green plants. At the same time, the water overflowing from the planting box flows out through the gap between the installation box and the planting box, and the debris is blocked by the mesh plate, so that the water flows into the installation box. At the same time, through the cooperation of the set drainage holes and the moisturizing layer, while reducing the rapid loss of water in the planting soil, the excess water can be infiltrated into the installation box below. Finally, the water is concentrated to the center through the two water guide plates at the lower end of the installation box, and finally the water is transported to the roof drainage position through the drainage pipe for discharge;

[0030] Step S7: Before the arrival of winter in the north and extremely cold weather, first move the device to a designated position through the four moving wheels at the lower end of the moving plate, then select the installation direction of the mobile protective structure, and take out the two blocking plates on the designated side of the installation box from the two operating slots;

[0031] Step S8: Under the action of the two operating sleeves and the two connecting shaft movable sets, the connecting rod and the shrinking sleeve are moved upward to a specified angle, and then the two clamping rods are pulled out of the two shrinking sleeves, and the four fixing pins at the lower ends of the two clamping rods are embedded in the two operating grooves on one side of the installation box. The two clamping rods are tightened by the two second springs between the shrinking sleeve and the clamping rod, so that the connection purpose of the mobile protection structure and the installation box can be achieved. At the same time, the first spring between the fixing plate and the operating rod can provide an upward pulling force to the operating rod. Therefore, the connecting rod and the shrinking sleeve on the other side of the operating sleeve have a downward rotation force, so the clamping effect of the four fixing pins and the operating grooves can be guaranteed;

[0032] Step S9: Make the two storage chutes correspond to the two guide grooves, and then connect the moving component to the two traction rods according to the installation direction. Through the cooperation of the moving component and the two traction rods, several protective frames can be driven to slide in the two storage chutes to the two guide grooves in turn, and the green plants are covered and protected by the transparent film between the several protective frames until the leftmost protective frame moves to one side of the installation box. The two movable limit rods at the lower end of the protective frame contact the outside of the installation box to limit the movement of the protective frame to ensure the overall protection effect of the protective frame. Through the four air inlet holes opened in the two fixed frames inside the protective frames on both sides, the hot air delivered by the hot air blower can be delivered to the inside of the several protective frames during use in winter to ensure the overall growth temperature of the green plants and avoid the death of the green plants in winter.

[0033] Preferably, step S9: take out the four traction ropes on the upper ends of the four winding wheels, and put two of the traction ropes on the upper ends of the two traction wheels of the installation box away from the driving box, and connect them to the traction rods on both sides of the protective frame, and then directly connect the other two traction ropes to the two traction rods, and when the protective frame is moved, the two motors in the two driving boxes are driven to rotate two of the driving shafts and the winding wheels to reel in the two traction ropes, and at the same time, under the action of the four gears on the upper ends of the four driving shafts meshing with each other, the other two driving shafts and the winding wheels rotate in the direction of rotation, and the other two traction ropes are released, and under the traction action of the two traction wheels, the purpose of moving the protective frame can be achieved.

[0034] Preferably, step S8: in the subsequent disassembly process, only one end of the operating rod needs to be pressed downward, and the connection position between the operating sleeve and the connecting shaft is used as a fulcrum to rotate the connecting rod and the shrinkage sleeve upward until the four fixing pins are separated from the two operating grooves, and under the contraction action of the two second springs, the two clamping rods are reset in the two shrinkage sleeves, thereby completing the separation and disassembly of the mobile protective structure and the installation box.

[0035] A green roof structure and construction method of a green building made by the technical solution of the present invention. One of the most important basic requirements for roof greening is waterproofing. Especially in rainy climates, the composite waterproof structure is used through multi-layer waterproof materials to further improve the waterproof ability of the roof, prevent rainwater from penetrating, and protect the roof and building structure from moisture damage;

[0036] Insulation layer: By setting up an insulation layer, the impact of the outside temperature on the interior of the building can be effectively reduced, and the insulation effect of the roof can be improved. Especially in cold seasons, the insulation layer can help maintain the indoor temperature and reduce energy consumption;

[0037] The first structural net: This layer mainly enhances the structural strength of the roof. It is composed of steel mesh and plays a supporting role to ensure that the roof can still bear the weight of plants and the pressure caused by changes in the external environment after greening.

[0038] Protective isolation layer: The protective isolation layer is to further improve the durability of the roof, prevent the erosion of the roof structure by plant roots, prevent the roots from penetrating the waterproof layer or affecting the basic structure, and it also provides additional physical protection and increases the stability of the overall structure;

[0039] The green planting structure adopted can prevent the plant roots from penetrating into the roof structure and damaging the waterproof layer and building by limiting the expansion of the plant roots. Through box planting, the planting positions of plants can be allocated and managed in a planned manner to avoid excessive growth and spread of plants. The box limits the space for root growth to prevent the roots from damaging the waterproof layer or building structure, ensuring the long-term service life of the roof. In addition to increasing the structural strength, the box installed on the outside can also collect excess liquid. Through the design of the box, excess water can be diverted and discharged to avoid water accumulation in the box, preventing the plant roots from being drowned or affecting the normal growth of the plants.

[0040] Through the mobile components, the mobile protection structure can adjust its direction according to the use needs and weather changes to adapt to different protection needs. Through the clamping and fixing components, the mobile protection structure can be quickly installed and disassembled, which is convenient for the maintenance and management of roof greening. When entering winter or encountering thunderstorms, the protection structure can be quickly deployed to cover the plants to prevent them from being damaged by cold air, snow or heavy rain.

[0041] The connection between several protective racks is done by transparent films to protect the plants from the weather while ensuring that they can get enough sunlight:

[0042] Does not affect plant lighting: The transparent film material is light-transmissive, allowing the plants to receive necessary sunlight while being covered, promoting plant photosynthesis and ensuring their healthy growth;

[0043] Covering protection: The transparent film not only serves as a shield, but also effectively blocks the damage of cold air, rain and snow to plants, especially providing a warm environment in extreme weather to prevent plants from being frozen or wet. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] Step S2: Move the composite waterproof structure to a designated position, apply mortar on the roof body 1, and then heat the composite waterproof structure again with a torch to slightly soften the internal adhesive layer 6 so that the composite waterproof structure can be slightly deformed to ensure the bonding effect with the roof body 1;

[0080] Step S3: After the composite waterproof structure is hardened, the thermal insulation layer 2 and the first structural mesh 3 are laid on the upper end of the composite waterproof structure in sequence;

[0081] Step S4: The staff casts the first concrete protective layer 8 on the first structural net 3 and the thermal insulation layer 2. Before the first concrete protective layer 8 is completely solidified, the anti-cracking net 9 and the third waterproof layer 10 are sequentially laid on the first concrete protective layer 8. Finally, the second concrete protective layer 11 is cast on the third waterproof layer 10 to fully wrap the anti-cracking net 9 and the third waterproof layer 10. Finally, the composite waterproof structure and the protective isolation structure are completely solidified.

[0082] Step S5: hoist the installation box 12 to the top of the roof by hoisting equipment, and fully adjust the position of the installation box 12 according to the greening requirements, then lay the moisture-retaining layer 18 at the bottom of the planting box 15, then fill the planting soil into the planting box 15, and then select suitable green plants to be planted in the planting soil according to the greening requirements and the temperature of the planting area, and support the planting box 15 in the installation box 12 by cooperating with the plurality of support rods 13 and the mesh plate 14;

[0083] Step S6: Then, the water inlet pipe group 16 is connected to the water source pipeline to ensure the stability of water supply for green plants. At the same time, the water overflowing from the planting box 15 flows out through the gap between the installation box 12 and the planting box 15, and the debris is blocked by the mesh plate 14, so that the water flows into the installation box 12. At the same time, through the cooperation of the plurality of drainage holes 17 and the moisturizing layer 18, while reducing the excessive loss of water in the planting soil, the excess water can be infiltrated into the installation box 12 below. Finally, the two water guide plates 23 at the lower end of the installation box 12 are used to concentrate the water to the center, and finally the water is transported to the roof drainage position through the drainage pipe 24 for discharge;

The two clamping rods 51 are tightened by the two second springs 50 between the shrinking sleeves 49 and the clamping rods 51, so as to achieve the purpose of connecting the mobile protection structure with the installation box 12. At the same time, the first spring 48 between the fixing plate 47 and the operating rod 46 can be used to provide an upward pulling force to the operating rod 46. Therefore, the connecting rod 45 and the shrinking sleeve 49 on the other side of the operating sleeve 44 have a downward rotation force, so that the clamping effect of the four fixing pins 52 and the operating grooves 20 can be guaranteed;

[0086] Step S9: Make the two storage chutes 29 correspond to the two guide grooves 22, and then connect the moving component to the two traction rods 34 according to the installation direction.
