A Grain Retaining Structure Used for One-piece Steel Structure Bulk Flat Storehouse

Abstract

The invention relates to a grain retaining structure for bulk bungalows with an integrated steel structure, comprising vertically arranged first steel columns and second steel columns; first force-transmitting steel beams and second force-transmitting steel beams parallel to each other , one end of the first force-transmitting steel beam and the second force-transmitting steel beam are vertically fixedly connected to the first steel column, and the other ends of the first force-transmitting steel beam and the second force-transmitting steel beam are vertically It is fixedly connected with the second steel column; it also includes a force-bearing member, the upper end of the force-bearing member is fixedly connected with the first force-transmitting steel beam through bolts, and the lower end of the force-bearing member is connected with the first force-transmitting steel beam through bolts. The second force transmission steel beam is fixedly connected. The structure of the present invention is simpler, the transmission path of force is optimized, and the traditional grain retaining column structure is canceled, so that the grain retaining structure is easy to install and the assembly efficiency of the grain retaining structure is improved.

Description

technical field [0001] The invention relates to the technical field of grain storage bungalows, in particular to a grain retaining structure for an integrated steel structure bulk bungalow. Background technique [0002] Grain bungalows are single-storey buildings that are used to store grain and meet the functional requirements of grain storage. , The construction speed is fast, and it has been widely promoted in recent years. [0003] The grain retaining structure of the existing steel structure bulk bungalow warehouse generally consists of two portal frame columns, and one or two grain retaining columns are arranged in parallel with the two portal frame columns, and the grain retaining column and the portal rigid frame The inner side of the frame column is flush, and the round steel or flat steel is arranged horizontally between the two portal frame columns. The three beams, this structural scheme has the following disadvantages: [0004] 1. The mechanical transmission ...

AI Technical Summary

Problems solved by technology

[0004] 1. The mechanical transmission path is complicated. The lateral force of the grain is first transmitted to the horizontally arranged round steel or flat steel, and then the force is transmitted to the vertically arranged grain retaining column through the round steel or flat steel, and then transmitted to the outside by the grain retaining column The three beams are finally transmitted to the portal frame column. During the force transmission process, after two lateral transmissions, the force transmission path is redundant, so structural optimization is required;

[0005] 2. It is difficult to install the grain-retaining column and the three outer beams. Since the three beams need to be installed with the portal frame column and the grain-retaining column, the installation holes of the three beams should be connected with the portal frame column and the grain-retaining column. The position accuracy requirements between the mounting holes are high, which often leads to difficult alignment of the mounting holes and difficult installation;

[0006] 3. There is a certain horizontal shear force at the root of the grain-retaining column in the existing structural scheme, so measures must be taken to resist the shear force during design. If a reinforced concrete independent foundation is designed for the grain-retaining column, the amount of earthwork excavation and backfilling will be large, which will lead to The cost increases and the construction period is extended; if the foundation beam is designed for the grain retaining column, the cost will increase more
