Description

Technical Field

[0001] This utility model belongs to the field of modular building technology and relates to a modular building foundation for polar snow. Background Technology

[0002] Antarctic scientific research and construction take place in an extreme environment with low average annual temperatures, high wind speeds, and thick ice sheets and upper snow cover, making natural conditions harsh. Polar construction generally adopts prefabricated building technology, where components and parts are prefabricated in factories, transported to the site for assembly and installation, aiming to complete construction in a high-efficiency and short-time manner.

[0003] Modular steel structure buildings are the most integrated, assembled, and efficient type of prefabricated steel structure building system. They have advantages such as high standardization and integration, fast construction speed, and the ability to be disassembled and relocated, highlighting the advantages of industrialized construction. They have been widely used in the specific functional requirements of building scientific research stations in polar regions.

[0004] The polar regions have typical inland climate characteristics, with heavy winds and severe snow accumulation. Due to wind disturbances and other factors, when strong blowing snow occurs, buildings face the risk of being buried by snow, leading to a series of problems such as shortened lifespan. Therefore, when modular buildings are used for Antarctic research stations, they are either elevated structures or buried under snow.

[0005] The modular building system, which is buried under the snow, especially the auxiliary units such as energy facilities, can integrate auxiliary facilities such as power supply and distribution, heating, and water treatment into the box-type modules. This facilitates the transportation of modules by sea and Antarctic ice sheet and on-site installation, shortens the on-site construction cycle, and meets the extremely short construction period requirements of the Antarctic inland ice sheet.

[0006] Conventional modular building foundations are typically cast-in-place or precast concrete structures buried underground, supported by soil layers. However, the Antarctic construction area generally lacks the foundation soil typically used in other buildings, making conventional cast-in-place or precast concrete foundation technologies unsuitable, and no mature technologies can be transferred or adapted. Summary of the Invention

[0007] The purpose of this utility model is to design a modular building foundation for polar snow, suitable for burying modular buildings under Antarctic snow; under the condition of no foundation soil, it adopts a form that is easy to prefabricate and assemble, adapting to local conditions and easy to implement; moreover, the materials are readily available, easy to standardize, realize industrialized production, and the on-site construction is convenient and efficient, without the need for large machinery; and it is also disassembled and recyclable.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A modular building foundation for polar snow-covered structures, the foundation being situated on compacted and leveled snow, comprising, from bottom to top, at least one layer of load-bearing insulation board, square timber, and steel beams serving as box-type modular foundation beams; wherein, the steel beams are spaced apart on the top surface of the square timber, the top surface of the square timber between the steel beams is fully covered with load-bearing insulation board, the load-bearing insulation board enclosing the side ends of the foundation, forming a wooden box-type foundation.

[0010] Preferably, the foundation is provided with at least two layers of load-bearing heat insulation boards, and the load-bearing heat insulation boards are arranged with staggered joints.

[0011] Preferably, the load-bearing heat insulation board is a wooden board or a rubber board.

[0012] Preferably, a steel beam is added to the foundation at the location where the equipment is placed.

[0013] Preferably, the load-bearing heat insulation board is an OSB board.

[0014] Preferably, shims are used to level the square timbers.

[0015] Preferably, the square timber is connected to the load-bearing heat insulation board below it by diagonal nailing.

[0016] Preferably, the steel beam is a structural steel section.

[0017] Preferably, the snow is formed by layering and compaction to form a hard shell layer as the basic bearing layer, with each layer having a thickness of no more than 300mm.

[0018] Preferably, the bearing capacity of the compacted snow foundation is not less than the bearing capacity required for the upper modular building.

[0019] In the design of the polar snow-covered modular building foundation described in this utility model:

[0020] The foundation uses a compacted, perennial, non-melting snow layer as the load-bearing base layer. The foundation structure is assembled from timber and steel, securing the upper box-type modules and providing reliable support.

[0021] This invention uses natural snow as the foundation, and mechanical compaction forms a hard crust layer on the snow surface as the foundation bearing layer. The snow is compacted in layers, with each layer not exceeding 300mm in thickness. The bearing capacity of the foundation after compaction is required to be no less than the bearing capacity required by the upper module, such as 50kPa.

[0022] The top surface of the square timber between the steel beams is fully covered with load-bearing insulation boards, which are then sealed off at the ends of the foundation. The load-bearing insulation boards and the square timber form a completely enclosed space, creating a wooden box-type foundation that achieves insulation and prevents heat conduction inside the modular house from causing the snow foundation to melt.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] Existing conventional modular building foundations, typically made of cast-in-place or precast concrete, cannot withstand the challenges of Antarctica's perpetually low temperatures.

[0025] The foundation bearing of this utility model uses compacted snow. In the absence of foundation soil, it adopts a form that is easy to prefabricate and assemble, adapting to local conditions and facilitating implementation.

[0026] The foundation of this utility model adopts a wooden box-type foundation design to achieve heat insulation effect and prevent heat conduction inside the modular house from causing the snow foundation to melt.

[0027] This utility model is easy to obtain materials, facilitates standardization, enables industrial production, and allows for convenient and efficient on-site construction without the need for large machinery; it is also detachable and recyclable. Attached Figure Description
