Abstract
Description
Technical Field
[0001] The present invention relates to the field of comprehensive land improvement, and in particular to a building with a roof supporting a large area of farmland. Background Art
[0002] Existing comprehensive land consolidation technologies aim to increase the area of land for urban and rural construction, or to increase the area of arable land, or to obtain certain types of land for specific purposes. They re-optimize and reorganize land resources such as fields, water resources, roads, forests, and land for village and town buildings within a two-dimensional plane. Requiring villagers to move into residential buildings en masse is difficult, time-consuming, and expensive. If these measures do not involve villagers' homesteads, the results of the consolidation are quite limited. Due to the requirements of the balance policy for the occupation and compensation of arable land and forest land, if a piece of land is occupied, it must be compensated with other land. When all resources are included in the management database and indicators are locked, the difficulty of comprehensive land consolidation increases, creating a huge obstacle to economic and social development.
[0003] However, existing farmland technology only utilizes the ground surface to a depth of about 50 to 60 cm, leaving the underlying space unused. If land resources can be utilized in a vertically integrated manner, it can greatly alleviate the conflict between the protection requirements of cultivated land, forest land, and urban and rural construction development land. Summary of the Invention
[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a building with a roof that can support a large area of farmland.
[0005] The present invention is achieved through the following technical solution: a building with a roof supporting a large area of farmland, which includes a building main body, a farmland part, a roof strip facility part, and a vertical transportation part.
[0006] The main building is a large-scale horizontal structure, creating a large roof area for supporting farmland. Conventional buildings are often short, ranging from approximately 10 to 20 meters in depth, to ensure good sunlight and ventilation. However, the ground between rows of conventional buildings is largely shaded, preventing direct sunlight and hindering crop growth. Designing large-scale, deep buildings can eliminate or reduce these ground shadows, creating a large area of direct sunlight on the roof. By combining building functions with varying lighting requirements, a large-scale, deep, integrated building can be created. Using the roof for farmland is beneficial for crop growth and mechanized farming. Farmland suitable for mechanized farming is generally no less than 200 meters long and 150 meters short. Therefore, a building with a roof supporting a large area of farmland could have a planar dimension of 200 meters by 150 meters.
[0007] Furthermore, the lighting and ventilation issues caused by the large depth require technical solutions. Therefore, the main building is elevated above the ground. Specifically, the interior floor of the main building is elevated above the exterior ground. This allows for side window lighting, creating an indoor side window lighting zone and addressing the lighting issues in the areas adjacent to the exterior walls. For example, by fully utilizing the side walls and providing side windows, natural light can be provided to the surrounding area of the building.
[0008] Furthermore, the farmland part is located above the roof panel of the main building part and is surrounded by retaining walls around the top of the main building part. The retaining wall is constructed using reinforced concrete and forms an integral structure with the roof panel of the main building part, which can resist the lateral thrust of the soil in the farmland part and the dynamic load and lateral thrust during mechanical tillage.
[0009] Furthermore, the roof strip-shaped facility part is mainly composed of the skylight and the roof ventilation tower, and other necessary roof facilities such as heat dissipation equipment, power equipment and necessary agricultural equipment are also combined into the roof strip-shaped facility part. Each of the roof strip-shaped facility parts is composed of one or more strip-shaped skylights, one or more roof ventilation towers and other necessary equipment with equal widths to form a long strip-shaped facility assembly. The long axis of the roof strip-shaped facility part is parallel to the main tillage direction of the agricultural machinery and is distributed in parallel at intervals along the north-south direction, that is, the long axis direction of the skylight points to the east-west direction, so as to obtain a more uniform lighting effect indoors. The roof strip-shaped facility part is designed to be strip-shaped, which can be well matched with the straight path of agricultural machinery tillage. A plurality of the roof strip-shaped facility parts are arranged in parallel and at intervals to separate a plurality of the farmland blocks. The short side length of each of the farmland blocks is a multiple of the agricultural machinery tillage width, which can improve the efficiency of agricultural machinery tillage and reduce the tillage repetition coefficient.
[0010] Furthermore, the vertical transportation part is used to connect the ground with the farmland part. Agricultural machinery can use the vertical transportation part to rise from the ground and enter the farmland. The specific transportation method can be a ramp, an elevator, etc. Considering the up and down of people, stairs can be set at the same time.
[0011] Furthermore, the interior of the main building is divided into a side window-lit area and a core area, with the core area being the area where side windows cannot provide daylight. Since the lighting requirements for a building's internal functions vary, functional zones can be reorganized based on the level of lighting requirements. For example, if raw materials for a product need to be brought in by the box, visual illumination is only needed to identify the box dimensions, so the lighting requirements are lower. However, the processing and operation of raw materials and parts require high illumination, which requires higher illumination on the work surface, or even artificial lighting. Functions with high lighting requirements can be concentrated in a strip-like arrangement, and the lighting problem in these areas can be solved by installing strip skylights in the roof. Skylights can be zigzag, rectangular, or flat. Each type of skylight has a lighting efficiency 1.2 to 2 times that of side windows, and their uniformity is better than that of side windows. Therefore, to achieve daylighting for the same indoor area, only smaller skylights are required, thereby reducing the area occupied by farmland above the roof. This area is the skylight-lit area. In order to maximize the area of the farmland portion, flat skylights can be used. Flat skylights are window openings in which the daylighting openings are basically parallel to the roof. Functions with low lighting requirements, such as toilets, archives, conference rooms, warehouses, garages, storage yards, restaurants, facility rooms, corridors, etc., are concentrated and arranged in strips, namely the dark areas. Skylights may not be provided in the dark areas, and they may be arranged parallel to and spaced apart from the skylight lighting areas, so that the scattered light resources of the adjacent skylight lighting areas can be borrowed, and they may also be consistent with the layout of the field separations of the farmland portion on the upper part of the roof. At the same time, in order to obtain relatively uniform sunlight throughout the day, the long axis of the strip-shaped facility portion of the roof points in the east-west direction. At the same time, both the skylight lighting area and the dark area need to be equipped with artificial light sources for supplementary lighting. Since skylights are not required in the dark areas, a larger area can be provided for the upper farmland.
[0012] Furthermore, large-scale buildings that use side windows for lighting often need to have partition walls installed inside, which blocks the horizontal wind and is not conducive to indoor ventilation. To this end, the internal corridor is extended and connected to the exterior facade, and an air duct opening is opened to form a through-flowing air duct. The air duct opening is equipped with a louver fence. The part of the internal partition wall adjacent to the air duct adopts a combination of ventilation louver partitions and opening and closing panels. By installing the ventilation louver partitions and opening the opening and closing panels, the rooms adjacent to the air duct can be connected to the air duct. By closing the opening and closing panels to isolate the noise, the indoor sound environment is controlled.
[0013] Furthermore, in the core area, rooftop ventilation towers are installed in different areas to assist in solving ventilation problems. Rooftop ventilation towers use fans to generate airflow. For areas that generate odor, noise, or require moisture isolation, hard partition walls (i.e., solid, airtight walls) or glass walls can be installed, and rooftop skylights and rooftop ventilation towers can be used to solve lighting and ventilation problems. Residential, office, and hotel functions that require high lighting and views can be arranged in the side window lighting area.
[0014] Furthermore, a water supply pipe and a drainage pipe are provided on opposite sides of the main building portion. The water supply pipe is higher than the drainage pipe, and the height difference between the two is no less than the height difference formed by the drainage slope of the farmland. The water supply pipe provides irrigation water for the farmland portion, and the drainage pipe provides a drainage channel for the farmland portion and a rainwater drainage channel for the main building portion. The irrigation method for the field can be traditional flooding, sprinkler irrigation, drip irrigation, etc., and the specific method is determined during the field design.
[0015] Furthermore, a waterproof layer is provided where the main building portion contacts the farmland portion. The specific construction method for this layer is a mature technology, and the waterproof layer is provided on the top surface of the roof panel, the inner side of the retaining wall, and the outer sidewall of the roof strip structure. To ensure smooth drainage, the roof panel has a slope of 1-2% in the drainage direction. The drainage direction and slope of the roof are consistent with those of the farmland portion, and the drainage direction is parallel to the long axis of the roof strip structure.
[0016] Furthermore, the farmland portion includes an insulation layer and a planting layer. The insulation layer is located at the contact portion between the farmland portion and the main body of the building, including the upper part of the roof panel, the inner side of the retaining wall, and the outer wall of the strip-shaped facility portion of the roof. The insulation layer is used to isolate the main body of the building from the influence of indoor and outdoor temperature changes on the farmland portion, such as: the temperature of the retaining wall increases due to sunlight, which may affect the soil temperature of the planting layer. The soil layers of the planting layer are distributed from top to bottom as follows: tillage layer, plow bottom layer, and heart soil layer (also called raw soil layer). The tillage layer is the topsoil layer that has been cultivated and matured. In this layer of soil, the crop roots are the most dense, the nutrient content is relatively rich, and it has a granular, granular or blocky structure. The thickness of the tillage layer is generally 12cm to 30cm, including the thickness of the repaired field ridges and ditches. The plow bottom layer lies below the tillage layer. This layer, compressed by the plow over long periods of time and deposited with clay particles during rainfall, forms a compact layered structure, typically 5 to 7 cm thick. The subsoil layer, located below the plow bottom layer, is compact and significantly retains water and fertilizer. This layer is typically 20 to 30 cm thick.
[0017] Furthermore, for buildings constructed on existing farmland with a roof supporting a large area of farmland, the cultivated soil layer of the original farmland must first be stripped and temporarily stored nearby. After the building construction is completed, this soil will be used as a new cultivated soil layer for the construction of the farmland portion. For buildings constructed in urban areas with a roof supporting a large area of farmland, the cultivated soil layer can be stripped off-site and used for the construction of the farmland portion.
[0018] Furthermore, the overall structure of the main building, including the foundation, columns, walls, roof panels, retaining walls, and side walls of the roof's linear features, is capable of bearing all static and dynamic loads from the farmland portion. Static loads include the gravity and lateral thrust of soil, irrigation water, precipitation, fertilizer, crops, farming machinery, personnel, vehicles, and equipment, while dynamic loads include the dynamic loads of farming machinery, personnel, vehicles, and equipment. To resist the lateral thrust generated by the farmland portion, the vertical walls of the upper roof, including the retaining walls and side walls of the roof's linear features, are constructed of reinforced concrete and form an integral structure with the roof panels.
[0019] Furthermore, the main building portion has one or more floors, and the vertical access points are ramps, vertical elevators, and stairs. Furthermore, if the main building portion has more than one floor, stairways and fire compartments may be installed within the main building portion based on its functionality and fire protection requirements. Increasing the number of floors in the main building portion can improve land use efficiency, but excessively high numbers can lead to significant costs associated with increasing irrigation water, necessitating a balanced economic approach. For example, if elevated canals are constructed directly upstream of the water source, increasing the number of floors in the main building portion can have significant socioeconomic benefits.
[0020] Furthermore, the main building structure may employ a frame structure, frame-shear structure, full-house foundation, pile foundation, strip foundation, or other structure, depending on the specific design conditions, to ensure structural safety. Water, electricity, and gas systems are configured according to the building's functional requirements. This is common knowledge in the architectural design industry.
[0021] Furthermore, the bottom of the skylight is in a trumpet-shaped form to reduce the obstruction of light by the side walls of the skylight.
[0022] The beneficial effect of this invention is that a building with a roof supporting a large area of farmland can effectively resolve the conflict between farmland and construction land in the competition for land space resources. Although the load on the farmland portion increases construction costs, the overall cost advantage is significant compared to reacquiring a piece of land and completing the corresponding occupation and compensation balance. This technology can be used on both construction and agricultural land, thus significantly saving land. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.
[0040] like Figure 1 As shown above, the multiple rows of conventional buildings 06 in the conventional building area 100 mostly adopt short depths to obtain better sunlight and ventilation conditions. However, most of the ground between the multiple rows of conventional buildings 06 is a shadow area 0501, which cannot be directly exposed to the sun and is not conducive to crop growth.
[0041] like Figure 1 As shown below, a building 200 with a roof supporting a large area of farmland includes a main building portion 10, a farmland portion 40, and a vertical transportation portion 50. The main building portion 10 is a large-scale horizontal structure, which provides a large roof area for supporting the farmland portion 40. The large-scale and deep main building portion 10 of this embodiment can eliminate or reduce shadow areas on the ground, forming a large area of direct sunlight on the roof, which is beneficial for crop growth and mechanized farming.
[0042] like Figure 1 and Figure 2As shown, the main building portion 10 is elevated above the ground level 01, allowing for natural light through side windows 15, creating a side window lighting zone 11 within the interior, addressing the lighting issues surrounding the exterior wall. The farmland portion 40 (including an insulation layer 41 and a planting layer 42) is located above the roof panel 30 of the main building portion 10 and is enclosed by a retaining wall 43 surrounding the top of the main building portion 10. The roof panel 30 and retaining wall 43 are integrally constructed of reinforced concrete and can withstand various loads and lateral thrusts on the farmland portion 40.
[0043] like Figure 2 and Figure 3 As shown, in the main building part 10, the area where the side windows cannot reach forms the core area 20. Figure 4 As shown, skylight 31 is set on the roof of the core area 20 to form a skylight lighting area 21. If the core area is required to have natural lighting, the skylight lighting area 21 can cover the core area 20 completely.
[0044] like Figures 5 to 8 As shown, functions with low or no lighting requirements can be concentrated in a strip layout. This part of the area is the dark area 22. The dark area does not need to have a skylight 31. It is arranged parallel to the skylight lighting area 21, so that it can be consistent with the field distribution pattern of the farmland part 40 on the upper part of the roof. Figure 4 、 Figure 6 、 Figure 8 As shown, the bottom of the skylight adopts a trumpet-shaped form to reduce the obstruction of light by the side walls of the skylight and improve the lighting efficiency.
[0045] like Figure 3 、 Figure 5 、 Figure 9 As shown, the side window lighting area 11 is in a circumferential form, and the interior space of the building often needs to be separated by a partition wall, resulting in poor horizontal through-ventilation. To this end, the internal corridor is extended to the exterior facade and an air duct opening 18 is set to form a through-ventilation duct 17. Figure 10 The partition wall adjacent to the air duct 17 is partially partitioned by a combination of ventilation louver partitions 13 and opening and closing panels 14. When the opening and closing panels 14 are open, the ventilation louver partitions 13 can connect the airflow of the adjacent room to the air duct 17; when the opening and closing panels 14 are closed, the sound insulation requirements can be met. The opening and closing panels 14 can be of a sliding door type, a sliding door type, or other structures. At the same time, combined with Figure 11Note that the rooftop ventilation tower 32 is installed in the core partition area to assist in addressing ventilation issues. For areas prone to odor generation, noise generation, and moisture isolation, airtight solid partition walls (not shown) can be installed. Rooftop skylights 31 and rooftop ventilation towers 32 can be used to address lighting and ventilation issues in these areas. Residential, office, and hotel functions with high lighting requirements and scenic views can be located in the side window lighting area 11 to facilitate viewing.
[0046] like Figure 11 As shown, the side facade of the building with a roof supporting a large area of farmland is a side window lighting surface. In addition to the necessary building entrances and exits 16 and several air duct openings 18, several side windows 15 are set on the side facade.
[0047] like Figure 11 As shown, agricultural farming machinery and equipment can be operated along the vertical transportation part 50 from the ground to the tillage layer 42 of the farmland part 40. Figure 4 、 Figure 6 As shown, the part where the farmland part 40 contacts the main building part 10 is provided with an insulation layer 41, including the upper part of the roof panel, the inner side of the retaining wall, and the outer side of the side wall 34 of the roof strip facility part, and the rest of the part is a planting layer. The insulation layer 41 is used to isolate the indoor temperature of the main building part 10 and the temperature of the retaining wall from affecting the farmland part 40. Figure 12 As shown, the soil layers of the planting layer 42 are distributed from top to bottom after the tillage structure matures as follows: tillage layer 4201, plow bottom layer 4202, and subsoil layer 4203 (also called raw soil layer). The tillage layer 4201 is the topsoil layer that has been cultivated and matured. In this layer of soil, the crop roots are most densely populated, the nutrient content is relatively rich, and it has a granular, granular or blocky structure. The thickness of the tillage layer is generally 12cm to 30cm, including the thickness of the repaired field ridges and ditches. The plow bottom layer 4202 is located below the tillage layer. Due to the compression of the plow during long-term cultivation and the deposition of clay particles with water during precipitation, this layer of soil forms a relatively compact layered structure with a thickness of generally 5cm to 7cm. The subsoil layer 4203 is located below the plow bottom layer. This layer of soil is relatively compact and has obvious water and fertilizer retention effects. The thickness of this soil layer is generally 20cm to 30cm.
[0048] like Figure 13 As shown, the skylight 31 and the roof ventilation tower 32 are integrated into the roof strip facility part 33. Other necessary roof facilities (not shown in the drawings) including heat dissipation equipment, power equipment, farmland equipment (not shown in the drawings) are also integrated into the roof strip facility part.
[0049] like Figure 14As shown, the roof strip facility part 33 (including skylights 31, roof ventilation towers 32 and other necessary roof equipment) divides the farmland part into several farmland blocks 46, and the short side size of each block is a multiple of the agricultural machinery tillage width 47, so as to reduce the repetition coefficient of the agricultural machinery tillage width 48 and improve the agricultural machinery tillage efficiency.
[0050] like Figure 15 As shown, the main body of the building has multiple floors, and the vertical transportation parts are ramps or vertical elevators and stairs. Increasing the number of floors of the main body of the building is conducive to improving land use efficiency.
[0051] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
