Description
Technical Field

Background
With the continuous increase of global population and the stable development of world economy, the demand for building construction still has higher growth space, and the increase of carbon emission still can be a first problem for preventing the rapid development of the building industry. Therefore, the urban building industry in the carbon emission key field still has the main melody of green building development in terms of reducing the carbon emission of building material production and building operation, and in addition, the carbon sequestration technology research and development of the building industry are accelerated, the carbon sequestration capacity of inorganic materials on building surface is improved, and the carbon sequestration technology is combined with popularization and application of production technology, so that the carbon sequestration technology becomes a new response way for global climate change in the current international building industry.
At present, inorganic materials such as concrete are still the main materials for building production. However, a part of carbon dioxide generated in the production of materials such as cement can be absorbed by the carbonization reaction of the materials, and with the gradual and severe international carbon emission reduction form, inorganic carbon is gathered as a third large carbon reservoir outside land plants and soil, and is widely paid attention to due to the huge reserves. The carbon sink principle of inorganic building material is CaO and SiO in cement2、Fe2O3、Al2O3Chemical components are easy to generate hydration reaction to generate unstable hydration products which can continuously react with CO in the air in use2The reaction occurs to generate stable carbonate and other substances, and the process is called carbonization reaction.
One of the main sources of high carbon emission in the building industry in China is the preparation of inorganic materials such as cement, and in the normal use state of the building service period, the carbonization reaction is extremely slow, and according to the research of scholars at home and abroad, the carbon absorption of concrete materials in the building operation period (50-100 years) only accounts for 7.6% of carbon dioxide generated in the material production and is far less than the greenhouse gas emission caused by the production of materials such as cement. The carbon fixation amount generated in the service period of a building is improved, but a compact surface is formed after carbonization reaction, so that the continuous contact reaction of carbon dioxide and materials is hindered, and the total carbon fixation amount of the building material is still limited. In addition, in the current building skin design, a design method aiming at increasing the carbon sequestration capacity of the building does not appear, and research on corresponding structure and node system design is also lacked. This patent aims at through the optimal design to details such as structure, node of building epidermis, further promotes the solid carbon performance of solid carbon building material, increases the solid carbon volume of building epidermis to replace the link plate after solid carbon cycle finishes, thereby realize full life cycle's building material solid carbon.

Detailed Description
The carbon-fixing building skin design of the invention is further described in detail by combining specific embodiments based on the design idea of the invention:
example 1.
The invention provides a method for designing a carbon-fixing hanging plate type building skin, which comprises the following steps: firstly, designing a prefabricated carbon-fixing type building surface member form, wherein the member form design is required to meet specific use functions, in the example, an indoor partition wall is taken as an example, and the partition wall member is required to be flat, attractive and convenient to construct, so that the indoor carbon-fixing hanging plate is designed to be of a standard size, is a square plate with the length and width of 600mm, and is designed to ensure the strength of the member, and the thickness design value of the member is not less than 30 mm; the bottom edge of the hanging plate is provided with a deep groove of 10mm, so that the hanging plate can be conveniently carried on the transverse groove type light steel, the top edge of the hanging plate is provided with a rabbet, after the bottom groove of the hanging plate is occluded with the transverse keel, the panel is straightened, the rabbet is lapped on the upper transverse keel, and finally the carbon-fixing hanging plate can be firmly carried on the keel by fixing through the special-shaped bolts with the flat heads at four corners.
Because the building outer skin is directly contacted with the outdoor environment, the climate difference between the south and the north is large, the outdoor climate factor can be set as a constant in the shape design of the hanging plate, the carbon absorption skin estimated based on the carbon fixation amount is mainly influenced by the surface area of the component, and the larger the formed surface area is, the higher the carbon fixation amount is, so the carbon fixation performance can be effectively increased and the time required by complete carbonization can be shortened by increasing the surface area coefficient of the building skin component in the building design. In the carbon-fixing building design, in order to adapt to the carbonization capacity of inorganic materials, the surface of the alkali-activated material is reduced to the greatest extent, and the alkali-activated material has higher plasticity, can form special texture or size modeling according to different molds, and meets the appearance of different building skins.
The invention provides a carbon fixation type detachable replaceable building surface design method, which comprises the following steps: channel steel with two sizes of transverse and vertical is combined and fastened in the partition wall to form a light steel keel system, vertical channel steel is arranged at intervals of 1200mm and fixed on the ground through bolts, and then transverse purlins are formed by galvanized C-shaped steel at intervals of 600mm and fixed on longitudinal channel steel through bolts; the 600 x600mm carbon fixing plate is supported in the transverse rigid groove, and the replacement steps are as follows: firstly taking off the flat-head special-shaped bolts at the four corners of the carbon-fixing plate, slightly pulling the top of the plate to enable the top of the plate to incline outwards a little, pinching the upper edge of the plate to lift upwards, completely taking out the carbon-fixing hanging plate, then inserting the non-carbonized hanging plate according to the original position, and finally screwing the bolts at the four corners into the anchor again.
The increase of stress load can slow down the carbonization rate of inorganic materials, so that the design of the carbon-fixing surface skin needs to be separated from a bearing system and an alkali-activated material (or cement-based, high-molecular and other carbon-fixing materials) is designed as a decorative material, different from the traditional concrete building. The effective carbonization area of the alkali-activated material (or cement-based, high-molecular and other carbon-fixing materials) is directly related to the carbonization efficiency, and the carbonization rate is increased in proportion to the increase of the exposed area. In the design of the carbon-fixing surface structure, effective carbonization area factors are fully considered, a dry-hanging method is selected as a structural lapping mode of the negative carbon surface, and compared with a wet-hanging method, the dry-hanging carbon-fixing material not only increases the carbonization surface, but also can be independently replaced after the surface material is damaged or completely carbonized.
In the carbon-fixing building design, the inner wall surface, the outer wall surface, the floor slab and the like can be set into carbon absorption interfaces as required, wherein the floor slab is difficult to detach and change at will due to bearing requirements, the separation design of the structure and the maintenance body in the building gives extremely high flexibility to the indoor partition wall, the total number of the indoor partition walls is higher in the building interface, and the carbon-fixing effect of the whole building can be obviously improved by the partition wall carbon-fixing design. The sound absorption material arrangement space can be reserved in the wall structure, and the sound insulation requirement can be met by adding the sound absorption material arrangement space according to the condition.
The handling problems of a large number of components are increased after the replacement of building skin component materials; the member with completely carbonized surface is crushed and reused, a large number of non-carbonized cross sections appear after crushing, the carbon fixing efficiency of the carbon fixing material is improved along with the increase of the contact area of the material and air, and the carbon fixing capacity of a building area can be rapidly improved by fully utilizing the increased area of the part.
Secondary utilization: in the case of a carbon-fixing type wall scene, firstly round steel with the diameter of 6mm is used for butting to form a plurality of spaces with the size of 600mmx600mmx200m (length, width and height), then a 4mm metal net sheet is cut into the size of 600mmx200mm and is placed into a round steel frame along the longitudinal direction, and then two pieces of metal nets with the area diameter of 4mm are paved on the outer side of the whole round steel frame; filling the round steel frame with the carbon-fixing material fragments layer by layer, and paving a layer of metal mesh with the size of 600mmx200mm on the fragments after filling one layer of fragments, and connecting the metal mesh with the round steel frame; finally, the frame is capped and moved to the position where the frame needs to be arranged.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the invention.
