Background technique

The non-load-bearing inner wall is called the partition wall. The partition wall of the mixing station silo is the separation structure of the sand and gravel silo. The silo is divided into several separate storage silos to ensure the respective storage of concrete aggregates such as sand and stone. After the sand and gravel are mixed, the ingredients of the mixing system are insufficient, which affects the strength of the mixture. The traditional silo partition wall of stockyard generally adopts the form of mortar rubble partition wall, brick-concrete partition wall, etc., and there are also newer structural forms such as steel mesh-filled gravel partition wall. However, the use of mortar rubble partition walls, brick-concrete partition walls, etc. has large investment, covers a wide area, has poor appearance, cannot be recycled, and has poor timeliness due to long curing time; although the steel mesh-filled gravel partition wall can be recycled However, it is limited to the recycling of some materials (such as steel columns), and the steel wire mesh is easy to be corroded and damaged, which will induce the leakage of filling and gravel, resulting in aggregates of sand and gravel, and it is difficult to repair.

The prior art discloses a reusable prefabricated storage silo partition wall of a mixing station (application number: 201420721158.3). Among the multiple I-beam columns of the partition wall, every other I-beam is preset. There are bolt holes, and bolt holes are also preset on the inverted U-shaped steel plate according to the positions of the preset bolt holes on the I-beam. The inverted U-shaped steel plate and the I-beam are fastened and fixed by bolts; on the corrugated steel plate, according to the I-beam Bolt holes are preset at the preset positions of the bolt holes, and bolts are used to fasten and fix the corrugated steel plate and the I-beam column.

This connection method is used for roofs and building exterior walls, which is sturdy and durable. When used for partition walls, there are disadvantages such as cumbersome installation, troublesome disassembly and assembly, excessive loss, and inability to reuse. Another assembled corrugated steel silo partition Although the wall can be disassembled and will not cause material waste, its structure is relatively complex, the prefabrication processing precision is high, and the installation method is not convenient and fast.
