5 TECHNICAL FIELD

[0001] The present disclosure relates to the field of construction of ice and snow buildings, and relates to an ice and snow landscape building with a transparent air-inflated membrane as shaping and supporting. 10  BACKGROUND ART

[0002] In recent years, with the development of ice and snow economy, ice and snow buildings as a unique architecture form have been loved by more and more tourists. Most of traditional ice and snow buildings are made of pure ice or snow as raw materials and are built by masonry or carving. Due to low strength, unstable mechanical property and large temperature sensibility of 15 the pure ice and pure snow materials, the development of the geometric profile, height and span of the ice and snow building is limited, and as the ice and snow building is generally a solid landscape building, the tourists cannot enter the ice and snow building to experience the ice and snow life, as such, a traditional construction mode is increasingly difficult to meet the ornamental requirements of tourists. 20

[0003] At present, the air-inflated membrane structure is used as a construction formwork to build the ice and snow building, and the construction formwork, i.e., the air-inflated membrane structure, needs to be dismantled after the ice and snow building is built, the aesthetics of the ice and snow building as well as the ice and snow experience of the tourists entering the stadium can be affected if the air-inflated membrane structure is not dismantled. However, after dismantling 25 the air-inflated membrane, the wind load, snow load, and ice shell self-weight subjected by the ice shell structure are completely bom by the ice shell itself, and the ice shell is easy to collapse during air-inflated membrane dismantling. As the ice shell serves as a load-bearing structure itself, the bearing capacity thereof is obviously influenced by external temperature changes; when the external ambient temperature rises to -10°C and higher, the structural strength is greatly reduced, 30 it is unsafe for the tourists entering the ice and snow building to experience the ice and snow life. Therefore, the ice and snow building built in such a construction mode is only suitable for the Harbin area which is extremely cold outdoor in winter, which is greatly influenced by regional conditions and shortened in service life; and such ice and snow building is high in energy consumption if being used for the four-season ice and snow world for ice and snow travel in 35 southern summer.

[0004] A method for form-finding and construction of an air-rib ice shell building disclosed by CN 109837984A provides a method for building an ice shell building using an air-rib air-inflated membrane; the air-rib air-inflated membrane is only a temporary structure to assist the construction of an ice and snow building, and the shaping inside the membrane structure is 40 seriously affected due to the existence of the air ribs, thus the air-rib membrane structure must be dismantled after the construction is completed. A method for building an ice shell building based on a composite ice and snow material disclosed by CN 110017026A provides a process flow for constructing an ice and snow building using a composite ice and snow material, it is not mentioned that the mould is an air-inflated membrane structure, the mould must be 16 03 23 dismantled after the construction is completed, otherwise the inside landscape of the ice and snow building may be affected. A ground cavity structure applied to a stacked ice and snow sports building disclosed by CN 107461855A and an ice brickwork capable of achieving colour change of ice and snow landscape lighting only provide an apparatus for 5 optimizing the performance of an ice and snow building, and do not involve an air-inflated membrane; an ice and snow stadium disclosed by CN 209412986U provides an ice and snow activity venue based on an air-inflated membrane, belonging to exhibition venues using an air-inflated membrane as an ice and snow landscape building. The ice and snow building is placed inside the air-inflated membrane for exhibition, which does not involve 10 using the air-inflated membrane as a construction formwork of the ice and snow building and supporting the ice shell.

[0034] The illustration in the figure only shows an umbrella shape, and any preset shapi ng can be made accordi ng to setti ng demands i n the specifi c appl i cati on of the layout of the stadiums, thus forming an architectural appearance with ornamental value.

[0035] The air-inflated membrane body can be spliced into any preset shape by cutting analysis according to design demands.

[0036] Or the material of the ai r-i nflated membrane body can employ a membrane made of a PV DF material as a planar membrane material for air-inflated membrane structure processing. By conducting cutting, grinding and heat-sealing operations on the obtained planar membrane material, an initial membrane sheet is processed into membrane units, the obtained membrane units are connected using aluminium alloy pressing plates and bolts, thus obtaining the corresponding air-inflated membrane body structure.

[0037] The shell ice layer is made of a composite ice material and is installed at the external of the air-inflated membrane body as a part of the ice and snow building, and the shel I i ce I ayer and the ai r- i nf I ated membrane body are mutual ly connected to form a whol e capable of being stressed mutually. The appearance of the shell ice layer should be in consistent with the shape of the air-inflated membrane body.

[0038] A construction method of the shell ice layer is specifically as follows: firstly, obtaining a thickness of the shell ice layer by a corresponding mechanical calculation, where the thickness can enable the shell ice layer to bear a certain own weight; mixing raw materials (water, reinforced fibers and polyurethane) into a composite ice and snow material after site preparation work is completed, where the reinforce fibers must have the hydrophilia; stirring the composite ice and snow material for a certain time to form flocculence, and spraying the flocculence to the outer side of the air-inflated membrane body, where the spraying operation should be completed layer by layer until a predetermined thickness is reached; and cooling to form the shell ice layer.

[0039] The composite material may also employ cotton, hemp, regenerated fibres, or straws.

[0040] The present disclosure is simple in structure, convenient for construction, stable in the whole building structure, and low in maintenance cost. The bearing capacity is strong as the ai r- i nf I ated membrane body and the shel I i ce I ay er are i ntegrated i n one pi ece; and due to the fact that the shel I i ce I ay er i s formed by spray i ng and cool i ng the composite ice material layer by layer, the shell ice layer can adapt to any shape and the shape is changeable, and the shape ice layer can be made to the greatest dimension to attract the tourists. By employing the transparent membrane material, the existence of the airinflated membrane body cannot affect indoor ice and snow landscape and shaping inside the ice and snow landscape building. There is no need to dismantle the air-inflated membrane body, the structure self-weight of the shell ice layer, external wind load and snow load can be completely born by the air-inflated membrane body, the shell ice layer structure of the i ce and snow bui I di ng does not bear any I oad by itself, thus the di mensi on of the ice and snow landscape building can be greatly increased.

[0041] The composite ice is only used as a shaping structure rather than a load-bearing structure, thus the influence of the temperature effect on the strength of the ice and snow materi al cannot affect the structural strength, the servi ce I i f e of the i ce and snow I andscape bui I di ng can be greatly i mproved, and the safety of the touri sts enteri ng the i ce and snow building to experience the ice and snow life can be greatly guaranteed.

[0042] After the ice and snow building is dismantled, the composite ice material and the air-inflated membrane body material can both be recycled, thus achieving energy conservation and environmental protection.

[0043] As the air-inflated membrane body is used as a bearing structure, the service life of the ice and snow building is greatly prolonged, and the safety of the tourists entering the ice and snow building for visiting is greatly guaranteed.

[0044] According to an existing ice and snow building with a non-transparent air -inflated membrane as a construction formwork, the ice and snow landscape of the ice and snow building is difficult to see indoors without removing the construction formwork, thereby affecting the playing experience; and the structural stability and the service life of the ice and snow building are affected if after the construction formwork is removed. In accordance with the present disclosure, the transparent air-inflated membrane and the shell ice layer are bonded into a whole, the structure of the shell ice layer can be seen indoors through the air-inflated membrane while the structure stability is enhanced, thus the playing experience of tourists is enhanced.

[0045] As the device and the method of use disclosed in the embodiment correspond to the method disclosed in the embodiment, the description is relatively simple, and relevant parts are described in the method part.

[0046] The previous description of the disclosed embodiments enables those skilled in the art to implement or use the present disclosure. Various modifications made to these embodiments are apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure.
