Steel-plate-externally-covered assembled round underground barn with prefabricated caulking strips

Abstract

The invention relates to a steel-plate-externally-covered assembled underground barn with prefabricated caulking strips. The flat shape of the underground barn is a round shape. The underground barn comprises multifunctional columns (1), a plurality of prefabricated barn wall plates (2), a barn roof (3), a barn bottom (4) and a plurality of prefabricated caulking strips (5), wherein the barn wall plates (2) are prefabricated steel plate-concrete arc-shaped plates in the flat plane; the peripheries of the barn wall plates (2) are connected with the multifunctional columns (1) and the prefabricated caulking strips (5) to from an integral round tube structure; the multifunctional columns (1) position the barn wall plates; the soil anchoring depth of the multifunctional columns (1) is greater than the depth of the barn bottom (4); and the multifunctional columns (1) are major stress components for bearing soil pressure and grain pressure and resisting the buoyancy force. The steel-plate-externally-covered assembled underground barn is characterized in that the multifunctional columns (1) are separated into a plurality of sections from top to bottom; a first layer of barn wall plate is arranged at the inner side of the first section at the uppermost layer; a second layer of barn wall plate is arranged at the inner side of the second section; the similar setting mode is used until the lowermost layer of barn wall plate is reached; and a round assembled underground barn structure is formed. The barn wall plates (2) are prefabricated composition plates formed by inner and outer side steel plates (9), anchor nails (10) and inner side concrete (11), and steel plates are covered on the periphery for opening sealing.

Description

technical field [0001] The invention relates to the technical field of underground granaries, in particular to an assembled circular underground granary with prefabricated caulking strips. Background technique [0002] Underground granaries are built under the shallow surface, which can store grain at low temperature all year round, maintain grain quality, inhibit the occurrence of pests, avoid fumigation with toxic chemicals, resist natural damage, and be used for both war and peace. Many experts and scholars agree that it is reasonable to promote the application of underground granaries The new system and new technology of grain storage can realize low-temperature environmental protection, energy saving and land saving, quality assurance and loss reduction, and ecological grain storage.

AI Technical Summary

Problems solved by technology

[0003] The existing underground granaries in my country are generally located in general loess and cohesive soil areas with low groundwater levels, such as cave warehouses, trumpet warehouses, double-curved arch warehouses, semi-underground warehouses, and cave-shaped trumpet warehouses; at the same time, most of the underground warehouses that have been built are made of bricks. Masonry structure, small storage capacity, large floor area and low degree of mechanization

[0004] In order to build a new type of underground granary that can be popularized and applied in areas with high groundwater levels and complex geological conditions, some national patents and documents have also proposed a circular granary, a large underground rectangle surrounded by cylinders and semi-cylinders, and a pile-enclosed compound type. There are still some problems to be solved in the popularization and application of the above-mentioned new warehouse types, such as: (1) High standard waterproof and moisture-proof requirements for underground grain storage to ensure that the warehouse body does not leak or seep within the service life

The coiled material used at this stage is easy to age, the construction process is complicated and difficult, and it is prone to construction quality problems

(2) The wet working environment of deep foundation pit has a long construction period

After the excavation of the foundation pit and precipitation, the cast-in-place construction of the warehouse floor and the sliding form construction of the warehouse wall need to be carried out in a wet working environment for a long time, which has high labor intensity, long construction period and high construction cost

(3) The cost of foundation pit support is high

The granary of this invention also requires foundation pit excavation, which has disadvantages such as troublesome construction, high construction cost, and long construction period.

[0007] Prefabricated structures are one of the effective ways to realize the industrialization of building structures and building energy saving and emission reduction. For a long time, concrete buildings mainly adopt the traditional operation method of on-site construction, with a low degree of industrialization, water consumption, energy consumption, artificial waste, and sewage discharge. The quantity is large, which does not conform to the national sustainable development policy of energy conservation and environmental protection
