Elevated stereoscopic cold storage based on grid structure

Abstract

The invention relates to an elevated stereoscopic cold storage based on a grid structure. The elevated stereoscopic cold storage comprises a raft foundation, a heat preservation structure and a bearing vertical column, the heat preservation structure is arranged on the hexahedron of the cold storage, the bearing vertical column is fixed to the raft foundation, the bearing vertical column comprisesa plurality of grid units which are sequentially connected, the grid units comprise connecting pieces and connecting rods for connecting the connecting pieces, and the bearing vertical column of thecold storage is formed by sequentially connecting the multiple grid units. The elevated stereoscopic cold storage has the beneficial effects that the bearing vertical column of the cold storage is a space system composed of the multiple grid units, and the advantages of good integrity of a space stress system, large rigidity, good seismic performance, high assembly precision, convenient assembly,lower construction cost and the like are achieved; and the grid units are accurately manufactured in advance by a factory, assembled and fixed on site according to a design drawing, the construction link is single, and the difficulty of construction management and quality control is greatly lowered.

Description

technical field [0001] The invention relates to the field of cold storage, in particular to an elevated three-dimensional cold storage based on a grid structure. Background technique [0002] In recent years, with the continuous expansion of my country's cold drink market, cold fresh meat market, meat extension market, aquatic product market, and fruit and vegetable market, the rapid growth of people's consumption of these perishable foods will promote further growth in the demand for cold storage. increase. The capacity of cold storage is also required to be larger and larger, and its form is gradually developing from multi-storey civil construction storage to elevated three-dimensional cold storage. [0003] The existing elevated three-dimensional cold storage is designed with a steel frame structure, and its load-bearing columns are all truss structures. Therefore, the load-bearing columns are made of large H-shaped steel or square steel. Compared with the rectangular car...

Problems solved by technology

[0003] The existing elevated three-dimensional cold storage is designed with a steel frame structure, and its load-bearing columns are all truss structures. Therefore, the load-bearing columns are made of large H-shaped steel or square steel. Compared with the rectangular cargo space of the shelf, the H-shaped steel is irregular and occupies a large area. It will cause part of the space in the warehouse to be unusable, seriously waste space, and reduce land utilization; the disadvantage of using square steel is that the amount of welding is too large

The column of the truss structure also has the following defects: 1. The column of the truss structure is inconvenient to assemble, the amount of steel is large, the amount of welding is large, time-consuming and laborious, the assembly accuracy is not high, and the labor cost is high

2. When the truss structure is used to build a super-large cold storage, larger hoisting equipment is required, and it is difficult to construct under the unfavorable conditions that the lower concrete structure has limited bearing capacity and there is no stop position for the hoisting machinery; 3. In order to hoist large H Sectional steel needs to be set on the base of the raft slab, which requires a deeper pre-embedded foundation, and then installs the installation platform, which destroys the flatness and integrity of the raft slab foundation, and the construction is difficult; 4. The load-bearing columns of the truss structure need to be larger The occupied area takes up a lot of cold storage space, and the volume ratio becomes smaller
