Problems solved by technology

The steel silos currently in use in the market, especially large deep silos, have poor stability due to their high height, large storage loads and wind loads. Measures such as enlarging the cross-section of the column and the warehouse wall to ensure its safety will result in complex structure, cumbersome construction and high material cost

Embodiment approach 1

[0020] combine Figure 1~4 , the present invention is a large-scale steel silo with a spiral hoop, which consists of a roof 1, a wall steel plate 2, a column 3, a spiral hoop 4, a base 5, and a connector 6. The pre-embedded steel plate of the base 5 is connected to the column 3, the steel plate 2 of the warehouse wall is connected to the column 3 by bolts, the roof 1 is connected to the column 3, and the spiral hoop 4 is connected to the column 3 through the connector 6, such as figure 2 shown. The connecting piece 6 is convenient for segmental connection of the spiral hoop, and can effectively prevent the column 3 from being too deformed under the action of hoop tension.

Embodiment approach 2

[0022] On the basis of Embodiment 1, according to actual engineering needs, the spiral hoop 4 can be connected to some of the uprights through the connecting piece 6, preferably every 3-5 uprights.

Embodiment approach 3

[0024] On the basis of Embodiment 2, the winding direction of the spiral hoop relative to the central axis of the steel silo can be clockwise or counterclockwise, and multiple sets of spiral hoops with the same winding direction or opposite winding directions can be added according to actual engineering needs. The angle between the winding direction of the spiral hoop and the column is preferably 20°-45°.

Abstract

The invention aims to provide a silo with spiral hoops. The silo comprises a silo top, a silo wall, a base and the spiral hoops. The silo wall is mounted on the base, the silo top is mounted on the silo wall, reinforcing columns are arranged on the silo wall, a connector is arranged on each reinforcing column, the spiral hoops are connected through the connectors so as to form a spiral hoop group which is wound along the silo wall spirally and clockwise or counterclockwise, and an included angle between a winding direction of the spiral hoops and each column is within a range from 20 degrees to 45 degrees. The spiral hoops can substitute for a traditional toroidal wind girder and keep continuous along the height direction of a silo body, and stability of the silo is good. The spiral hoops can be used as lateral supports of the columns, so that bearing capacity of the columns is improved, cross-section areas of the columns are decreased effectively, and engineering cost is lowered. The spiral hoops can bear part of toroidal pressure of material storage load on silo wall plates, thicknesses of the silo wall plates are decreased effectively, steel is saved, and cost is lowered.

Description

technical field [0001] The present invention relates to a storage device, in particular to a large silo for storage. Background technique [0002] The steel silo is a cylindrical storage warehouse for storing powder, granules and lumps. The steel plate cylinder has large storage capacity, low cost, small space occupation, and fast construction period. Its application scope has been extended to grain, oil, cement, coal and other fields. The existing steel silos in the market, especially large deep silos, have poor stability due to the high height of the silos, large storage loads and wind loads. Measures such as enlarging the section of the column and the warehouse wall to ensure its safety will result in complex structure, complicated construction and high material cost. Contents of the invention [0003] The purpose of the present invention is to provide a silo with a spiral hoop instead of the traditional ring structure. [0004] The purpose of the present invention i...
