[0001] The present invention relates to the technical field related to construction engineering, and particularly relates to an inner-lined air film for the protection, renewal and reuse of old buildings. Background Art

[0002] At present, for the protection, renewal and reuse of a large number of old buildings, engineering measures such as demolition and reconstruction, renovation, repair and decoration are usually adopted, which are not conducive to the protection of old buildings and their architectural styles. Due to the implementation of the above-mentioned projects, the attributes, types, usage functions, facade images, land use properties, planning conditions or ownership relationships of old buildings will inevitably be changed, and administrative licenses and construction applications and other approval procedures must be applied for. It mainly involves departments such as asset management, land, planning, construction, cultural relics protection, environmental protection, work safety supervision, traffic management, market, urban management, emergency, real estate management and municipal public utilities.

[0003] Due to the large number of approval departments, the approval procedures and formalities are complex. Implementing the above-mentioned projects requires a large amount of human resources and a lot of time for the preliminary work.

[0004] Implementing the above-mentioned demolition and reconstruction and renovation projects requires the mandatory implementation of current construction standards and engineering technical specifications, such as fire prevention, energy conservation, environmental protection, green building and safety, etc. If the cost of implementing current construction standards and engineering technical specifications is too high, or cannot be implemented, it will directly lead to the technical infeasibility of demolition and reconstruction and renovation projects.

[0005] Implementing the above-mentioned demolition and reconstruction, renovation, repair and decoration projects has a long construction period, is greatly affected by seasonal climate, has a great impact on the surrounding environment, has many construction safety risk factors, and is prone to rights protection or complaints. It is difficult to reconstruct some old buildings on the original site after demolition.

[0006] Implementing the above-mentioned renovation, repair and decoration projects is difficult to achieve the purpose of usage function and protection, renewal and reuse.

[0007] In short, implementing the above-mentioned projects for the protection, renewal and reuse of old buildings has great management difficulty, high construction cost, long construction period, many uncertain factors, high project risk, poor economic rationality and social adaptability, and the uncertain factors, risks and costs increase sharply. Therefore, implementing the above-mentioned projects results in the products and services not being able to be launched on the market in time, missing market opportunities. Summary of the Invention

[0008] In order to solve one or several of the technical problems existing in the prior art, the present invention provides an inner-lined air film for the protection, renewal and reuse of old buildings.

[0009] The technical solution of the present invention to solve the above technical problems is as follows: An inner-lined air film for the protection, renovation, and reuse of old buildings, comprising an old building and an inner-lined air film, wherein the inner-lined air film is lined inside the main structure or the inner side of the exterior enclosure structure of the old building.

[0010] The beneficial effects of the present invention are as follows: The inner-lined air film for the protection, renovation, and reuse of old buildings according to the present invention is conducive to the protection, renovation, and reuse of old buildings; by directly filling the air film inside the old building, the type, main structure, land use nature, planning conditions, and real estate ownership of the old building are not changed, the main structure or its exterior structure of the old building is retained, the old building is preserved, and its architectural style is protected. The inner-lined air film forms a building space with its lightweight and flexible materials and forms an independent structural system, which can meet the building functions such as seismic protection, fire safety, sunlight lighting, sound insulation, ventilation and air exchange, wind and waterproofing, heat insulation, energy conservation and environmental protection, green ecology, explosion and pressure relief, air purification, and internal positive pressure required by relevant standards and specifications.

[0011] Among them, the inner-lined air film of the present invention does not damage, change, or weaken the structural system, stiffness, strength, and integrity of the old building.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Further, the old building includes cultural relics buildings protected by law and allowing development and utilization, old buildings with utilization value, buildings that have completed the main structure, or buildings that have been shut down and abandoned. It also includes existing buildings (structures) that can be reused or other facilities that can be reused.

[0014] Among them, the utilization of the structure is as follows: The inner-lined air film using the idle space under overpasses, viaducts, and rail transit road bridges. Or, the inner-lined air film using the idle space inside cooling towers, industrial kilns, and blast furnaces. Or, the inner-lined air film using the idle space of other structures. Or, the inner-lined air film using the idle space of caves such as mountain caves, rock caves, karst caves, and mine caves.

[0015] Among them, the old buildings described in the present invention include but are not limited to buildings that have completed the main structure or the main part, buildings that have been shut down and abandoned, buildings with structurally safe appraisals, and buildings with cultural relic protection and heritage protection values.

[0016] Further, after the inner-lined air film is inflated, its main body is wrapped in the envelope space formed by the main structure or the exterior enclosure structure of the old building;

[0017] The structural system of the inner-lined air film is independent of the main structure or the exterior enclosure structure of the old building.

[0018] Furthermore, after the inner-lined air film is inflated, its outer film surface is adaptively fitted within the envelope space formed by the main structure or the peripheral enclosure structure of the old building.

[0019] Furthermore, the film surface of the inner-lined air film is adaptively fitted to the local protrusions of the main structure or the peripheral enclosure structure of the old building and the local protrusions of the non-removable components of the old building;

[0020] Or, the film surface of the inner-lined air film is formed with an inward concave profiling for accommodating the local protrusions of the main structure or the peripheral enclosure structure of the old building and the local protrusions of the non-removable components of the old building.

[0021] Furthermore, there are vertical side columns arranged on the inner side of the outer wall of the old building, and the film surface of the inner-lined air film is provided with an inward concave profiling that penetrates up and down, and the side columns are placed within the corresponding inward concave profiling.

[0022] Furthermore, there are horizontal roof truss beams arranged on the inner side of the roof of the old building, and the film surface of the inner-lined air film is provided with an inward concave profiling that penetrates left and right, and the roof truss beams are placed within the inward concave profiling.

[0023] Specifically, only part of the main structure or the peripheral enclosure structure components of the old building protrude into the film surface of the inner-lined air film, and the film surface of the inner-lined air film is shaped by depression, avoidance, inward concavity or bypassing, etc. at this place; or only part of any non-removable components, devices or facilities of the old building protrude into the film surface of the inner-lined air film, and the film surface of the inner-lined air film is shaped by depression, avoidance, inward concavity or bypassing, etc. at this place.

[0024] Furthermore, a second drain pipe that penetrates both the inside and outside of the old building is provided at the bottom of the old building, and the second drain pipe is communicated with the lower end of the inward concave profiling.

[0025] Furthermore, an opening is formed on the inner-lined air film for the local protrusions of the main structure or the peripheral enclosure structure of the old building and the non-removable components of the old building to penetrate through the film surface, and the opening is sealed and wrapped with a watertight and airtight flexible connection member around the film surface and the local protrusions on the periphery of the opening.

[0026] The watertight and airtight flexible connection member can adopt an annular structure and is used to connect the membrane surface around the opening and the local convex part. The material of the watertight and airtight flexible connection member can be wooden board, (composite insulation) metal plate, cement wood fiber board, cement steel fiber board, glass fiber reinforced concrete board (GRC), resin glass fiber board (FRP), PVC board, special-shaped glass board, PPR (Polypropylene Random Copolymer) board, silicone board, etc., or a combination of the above boards. Which board is selected to make the "member" and whether it is prefabricated in the factory or fabricated on site depends on the actual project and regulatory requirements. The connection method between the member and the membrane surface and the local convex part can adopt mechanical connection methods, such as on-site thermal welding or bolt connection, etc. Since the air film cannot be directly connected to the corresponding local convex part, the watertight and airtight flexible connection member can be used to play an intermediary role to avoid air leakage or water leakage at the connection. Moreover, when these boards are used to make the watertight and airtight flexible connection member, they should have durability, fire resistance, heat insulation, etc., that is, they do not leak air or water, and also need to have certain mechanical properties, such as flexibility.

[0027] Among them, when it is indeed necessary for the main structure of the old building or its peripheral enclosure structure member to partially penetrate the membrane surface of the inner-lined air film, the membrane surface of the inner-lined air film shall take construction measures such as opening, splicing and sealing at this place. Or, when it is indeed necessary for any non-removable member, device or facility of the old building to partially penetrate the membrane surface of the inner-lined air film, the membrane surface of the inner-lined air film shall take construction measures such as opening, splicing and sealing at this place.

[0028] Furthermore, the inner-lined air film forms a drainage depression with a centripetal slope concave at the inner concave shaping or / and the opening.

[0029] Furthermore, an internal drainage facility is provided at the bottom of the drainage depression.

[0030] Furthermore, the shape of the drainage depression is bowl-shaped, teapot-shaped, vase-shaped, tile vat-shaped, goblet-shaped, fish basket-shaped or Möbius ring-shaped.

[0031] Among them, the drainage depression has functions such as waterproofing, water collection, drainage, heat insulation, daylighting, landscape and membrane internal environment control. The installation and fixation of the drainage depression are suspended, and it may fall on the floor of the old building or may penetrate the floor of this layer. The drainage depression is connected to the inner-lined air film or / and the main structure member of the old building or its peripheral enclosure structure member or any non-removable member, device or facility.

[0032] The water collection and drainage depression is made of waterproof materials. The water collection and drainage depression has a certain water collection capacity and can suppress instantaneous heavy rain. The water collection and drainage depression should have the same heat preservation performance as the inner lining type. The water collection and drainage depression can be used as a lighting facility when necessary. The water collection and drainage depression is a unique landscape facility. The water collection and drainage depression is used for the control of the inner environment of the membrane.

[0033] Furthermore, the membrane surface of the inner lining type air film is flexibly connected to the old building locally, and the bottom of the inner lining type air film is flexibly connected to the old building.

[0034] Specifically, the outer membrane surface of the inner lining type air film is flexibly connected to the positioning, limiting, watertight and airtight devices installed on the main structure or the peripheral structure of the old building.

[0035] Furthermore, an external drainage facility is provided at the bottom or / and the periphery or / and the outer edge of each corresponding layer of the old building of the inner lining type air film.

[0036] Furthermore, the external drainage structure includes a first drain pipe and a drainage slope. A first drain pipe penetrating through both sides inside and outside the building body is provided at the bottom of the old building, and a drainage slope is provided on the outer peripheral side of the lower end of the inner lining type air film. The drainage slope is communicated with the first drain pipe.

[0037] The external drainage structure further includes a water dispersing slope, a drainage open ditch, a drainage blind ditch, a sump or other water collection and drainage facilities, and these drainage facilities are communicated with the first drain pipe for drainage.

[0038] The internal drainage structure includes a second drain pipe. A sump can also be provided in the inner lining type air film, and a mechanical drainage facility and a third drain pipe can be provided.

[0039] Furthermore, the water collection and drainage depression is arranged on the middle column under the inner drainage gutter on the roof of the old building;

[0040] Or / and, the water collection and drainage depression is arranged on the non-removable components of the old building.

[0041] Furthermore, the old building includes a multi-story building body, and the inner lining type air film is filled on the inner side of the outer wall of each floor of the building body.

[0042] The beneficial effects of adopting the above further scheme are as follows: The main body of the inner lining type air film is completely sleeved inside the main structure or the peripheral protection structure of the old building, and can be applied to multi-story and high-rise old buildings or their basements.

[0043] The inner lining type air film of the present invention does not damage, change or weaken the structural system, stiffness, strength and integrity of the old building.

[0044] Among them, the water-collecting and draining depression in the present invention has a certain water-collecting capacity and can suppress instantaneous heavy rain. The water-collecting and draining depression has the same heat preservation performance as the inner-lined air film. When necessary, it can also be used as a lighting facility, a landscape facility, and even participate in the control of the air film environment, etc.

[0045] Moreover, the installation and fixation of the water-collecting and draining depression are suspended. It may fall on the ground of an old building or pass through the floor of this layer. The water-collecting and draining depression is connected to the inner-lined air film or / and the main structural members of the old building or its peripheral enclosure structural members or any non-removable members, devices or facilities.

[0046] The present invention is an inner-lined air film for the protection, renewal and reuse of old buildings. Compared with the current housing renovation, repair and decoration projects, it has the following advantages:

[0047] (1) The inner-lined air film for the protection, renewal and reuse of old buildings and its construction method replace a part of the current housing renovation, repair and decoration projects with an engineering method that has minimal impact, higher quality, faster speed, less resource input, and is safer and more environmentally friendly.

[0048] (2) The demolition of the inner-lined air film for the protection, renewal and reuse of old buildings is more convenient, with a fast demolition speed, little impact and less construction waste.

[0049] (3) The inner-lined air film for the protection, renewal and reuse of old buildings is more suitable for the following cases:

[0050] 1) Upgrading the production site of low-end manufacturing to the production site of high-end manufacturing;

[0051] 2) Upgrading the labor-intensive production site to a technology-intensive R & D site;

[0052] 3) Upgrading the extensive production site to a precise and clean production site;

[0053] 4) Transforming the production site with high energy consumption and pollution sources such as noise, dust, flue gas, and odor into an energy-saving and environmentally friendly clean production site;

[0054] 5) Transforming the "old three highs" industries into the "new three highs" industries.

[0055] (4) It is more economical, reasonable, safe, reliable, advanced and fast than engineering methods and technical measures such as demolition and reconstruction, renovation, repair and interior decoration, and is also more in line with the overall goal. Since the land use nature, planning conditions and ownership of the old building have not been changed, applying for engineering permits and construction filing procedures is more rapid and convenient.

[0056] (5) Applying the superiority of air-supported membranes and the engineering methods and technical measures of the inner-lined air-supported membrane is more conducive to controlling the project quality, cost, and construction period; it is more conducive to safety, energy conservation, environmental protection, green building, and meeting the standards of occupational health. With the least amount of materials and the lightest self-weight, a relatively large building space can be obtained. The inner-lined air-supported membrane and its components are all prefabricated in the factory and quickly assembled at the construction site. Its components can be transported over long distances or by combined land and sea transportation, without being restricted by the transportation radius.

[0057] (6) The materials and structure ensure the airtightness, watertightness, weather resistance, and durability of the inner-lined air-supported membrane; since the membrane material is a flexible material with a light self-weight and is lined inside the main structure and the outer envelope structure of the old building, the external forces such as wind, snow, and earthquake are weak. The lightning protection and lightning strike prevention devices and systems can be arranged relying on the old building. The self-provided thermal insulation and heat insulation structural measures have no cold / hot bridges and have excellent thermal engineering and building energy-saving performance. After being inflated and formed, the subsequent construction and installation operations inside the membrane are not affected by adverse weather or winter and rainy seasons.

[0084] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0085] Embodiment 1

[0086] As Figures 1 to 21 shown, an inner lining air film for the protection, renovation and reuse of old buildings according to this embodiment, the inner lining air film 2 is lined inside the main structure or the inner side of the enclosure structure of the old building.

[0087] The structural system of the inner lining air film 2 in this embodiment is independent of the main structure or the enclosure structure of the old building; after the inner lining air film 2 is inflated, its main body is wrapped in the envelope space formed by the main structure or the enclosure structure of the old building; after the inner lining air film 2 is inflated, its outer membrane surface fits and adheres to the envelope space formed by the main structure or the enclosure structure of the old building.

[0088] An optional solution in this embodiment is that the lower end of the inner lining air film 2 is connected and fixed to the base 13, the outer wall 1 or the ground beam at the bottom of the building body; specifically, an air lock component can be connected to the bottom of the lower end of the inner lining air film 2 and fixed on the base 13, the outer wall 1 or the ground beam at the bottom of the old building. Structures such as external windows 10 can be provided on the outer wall 1 of the building body.

[0089] Another optional solution in this embodiment is that the lower end of the inner lining air film 2 is connected and fixed to the base 13, the outer wall 1 or the ground beam at the bottom of the old building, and the membrane surface of the inner lining air film 2 is also connected and limited to the inner side of the outer wall 1 of the old building through the limiting structure 24. This is beneficial to the stable installation of the inner lining air film inside the old building.

[0090] As Figure 1 and Figure 3 shown, a specific solution in this embodiment is that a first drain pipe penetrating both the inside and outside of the old building is provided at the bottom of the old building, and a drainage slope is provided on the outer peripheral side of the lower end of the inner lining air film 2, and the drainage slope is communicated with the first drain pipe. The first drain pipe and the drainage slope serve as the outer drainage structure 31. By providing the first drain pipe and the drainage slope, it is convenient for draining water from the membrane surface of the inner lining air film.

[0091] The roof of the old building of this embodiment can be a single-span roof or a continuous-span roof. The roof is provided with structures such as a roof panel 5 and a purlin 51.

[0092] When in use, a lined air membrane based on the protection, renewal and reuse of old buildings in this embodiment uses air handling equipment and air supply and return facilities to inflate the membrane and maintain positive pressure inside the membrane. In addition, the air handling equipment and air supply and return facilities also have the functions of adjusting or controlling air temperature and humidity, cleanliness, oxygen content, toxic gas content, fresh air volume and ventilation times, wind speed and direction, etc. In the event of a fire, the air handling equipment and air supply and return facilities will switch to a mechanical air supply and smoke prevention system and a smoke exhaust system. After the lined air membrane is inflated and formed, avoid, apply to or insert the main structural components of the old building. The matching entrances and exits are passage facilities for pedestrians or logistics to cross the critical surface of the pressure difference, usually with swing airtight doors and rotating airtight doors. A dedicated channel for motor vehicle traffic is equipped with an alternately opened airtight rolling shutter door.

[0093] In this embodiment, a lined air membrane based on the protection, renewal and reuse of old buildings is used, and the space matching method between the lined air membrane and the old building is adopted, including simple single-span wrapping, single-span wrapping around beams, single-span wrapping around beams and side columns, continuous span through middle columns, etc. The lined air membrane surface and the old building structural parts are combined in a manner of avoidance, application and interlacing.

[0094] In this embodiment, a lined air membrane based on the protection, renewal and reuse of old buildings is directly filled with an air membrane structure in the old building, without changing the land use nature, planning conditions and real estate ownership of the old building, preserving the main structure of the old building or its peripheral structure, and retaining the old building and its architectural style. The lined air membrane forms a building space with its lightweight and flexible materials and forms an independent structural system, which can meet the building function requirements of relevant standards and specifications such as earthquake protection, fire safety, sunlight and lighting, sound insulation, ventilation, wind and water resistance, thermal insulation, energy saving and environmental protection, green ecology, explosion and pressure relief, air cleanliness and internal positive pressure.

[0095] Example 2

[0096] On the basis of Example 1, Figures 1 to 4 As shown, the outer membrane surface of the lined air membrane 2 of this embodiment is adaptively fitted to the local raised portions of the main structure or the external protective structure of the old building and the local raised portions of the non-removable components of the old building.

[0097] like Figure 15 As shown, the inner side of the outer wall 1 of the old building has vertically arranged side columns 11, and the outer membrane surface of the lined air membrane of this embodiment is adaptively fitted with the side columns 11.

[0098] likeFigure 16 As shown, the inner side of the roof of the old building has a horizontally arranged roof truss beam 12, and the outer membrane surface of the inner lining type air film in this embodiment is adaptively attached to the roof truss beam 12.

[0099] Embodiment 3

[0100] On the basis of Embodiment 1, as Figures 5 to 14 shown, the outer membrane surface of the inner lining type air film 2 in this embodiment is formed with a partial convex part for accommodating the main structure or the peripheral enclosure structure of the old building and an inner concave profiling for the non - removable components of the old building.

[0101] As Figure 8 , Figure 11 and Figure 14 shown, the inner side of the outer wall 1 of the old building has a vertically arranged side column 11, and the air film 2 of the inner lining type is provided with a vertically - through inner concave profiling 22, and the side column 11 is placed in the corresponding inner concave profiling 22, specifically as Figure 17 shown. Making the inner lining type air film have an inner concave setting is beneficial for the inner lining type air film to fit better with the internal structure of the old building.

[0102] Specifically, the inner concave profiling 22 can be a depression or a notch, and the specific size is adapted to the corresponding partial convex part.

[0103] Preferably, as Figure 8 , Figure 11 and Figure 14 shown, the inner lining type air film 2 on both sides of the inner concave profiling 22 is connected and limited to the inner side of the outer wall 1 of the old building through a limiting structure 24. It is beneficial for the inner lining type air film to be stably connected inside the building body. Among them, the limiting structure can adopt a U - shaped steel structure.

[0104] Specifically, the bottom of the old building is provided with an external drainage structure that penetrates both the inside and outside of the old building, and the external drainage structure can be communicated with the lower end of the inner concave profiling 22. By setting the second drain pipe, the inner concave profiling can take into account the drainage of the inner lining type air film surface.

The side columns 11 are hermetically connected to the opening, and the opening is hermetically wrapped with a watertight and airtight flexible connecting member 26 around the film surface of the opening and local penetrating structures or components such as Figure 19 shown.

[0109] Embodiment 6

[0110] Different from Embodiment 4, as Figure 20 shown, on the inner side of the roof of the old building in this embodiment, there are horizontally arranged roof truss beams 12. An opening for the roof truss beams 12 to pass through can also be opened on the inner lining air film. The roof truss beams 12 are hermetically connected to the opening, and the opening is hermetically wrapped with a watertight and airtight flexible connecting member 26 around the film surface of the opening and local penetrating structures or components such as Figure 20 shown.

[0111] Embodiment 7

[0112] Based on any one of Embodiments 1 to 6, as Figure 2 , Figure 10 , Figure 13 shown, in this embodiment, a recessed structure is provided as a water collection and drainage depression at the non - removable component 52 of the old building. As Figure 2 shown, the non - removable component is an in - convex structure. The lower end of the water collection and drainage depression can also be connected to the internal drainage structure 3, and the water collection and drainage depression can be supported by a water collection and drainage depression bracket 25. As Figure 10 shown, if the non - removable component is a middle column, the water collection and drainage depression can directly penetrate through this middle column.

[0113] Embodiment 8

[0114] Based on any one of Embodiments 1 to 7, as Figure 1 , Figure 5 , Figure 9 and Figure 12 shown, when the roof is a continuous - span roof, a water collection and drainage depression can be set at the continuous - span position. As Figure 2 , Figure 6 , Figure 10 and Figure 13 shown, the water collection and drainage depression at the continuous - span position is provided with an opening and penetrates through the middle column 19 at the continuous - span position. The lower end of the water collection and drainage depression at the continuous - span position can also be connected to the internal drainage structure 3. That is, the bottom of the water collection and drainage depression 23 has an opening, and this opening is flexibly and hermetically connected to the middle column. The opening is hermetically wrapped with a watertight and airtight flexible connecting member around the film surface of the opening and local penetrating structures or components, such as Figure 2 , Figure 6 , Figure 10and Figure 13 as shown

[0115] Example 9

[0116] As Figure 21 shown, the old building in this embodiment includes a multi-story building body 4, and the inner side of the outer wall 1 of each floor of the building body is filled with the lining type air film 2. The multi-story building body 4 can have multiple floors above the ground and multiple floors underground.
