Description

TECHNICAL FIELD

[0001] The utility model relates to attic type goods shelf warehouse floor repairing field, concretely is a kind of coordination promotion leveling repair structure for uneven settlement deformation of attic type goods shelf warehouse floor and goods shelf column foot. BACKGROUND

[0002] With the rapid development of logistics industry, the overall scale of China's logistics industry is rising, and various large-scale warehouse construction facilities are increasing. However, most of the warehouses are mainly in the transportation convenient areas along the coast and the river. Such areas are basically filled with soft soil or have not completed self-weight consolidation. When the pre-construction treatment of such soft soil foundation is not in place and the warehouse area floor load is too large, the additional load generated on the floor foundation is relatively large. Therefore, during use, uneven settlement of the floor often occurs in the warehouse building, resulting in a "concave" or "pot-shaped" ground in the warehouse area. Even the maximum settlement of the local point of the warehouse building floor reaches 50 cm, which will seriously affect the normal use of the warehouse and bring potential safety hazards. For the widely used new attic type goods shelf warehouse, the goods shelf is usually one or more layers, and the warehouse is installed uniformly after the floor construction is completed. The self-weight of the load on the attic type goods shelf is transmitted to the column foot by the steel column, which causes stress concentration at the column foot position relative to the floor area. Since the floor structure is rigidly connected with the column foot, local excessive settlement of the column foot area is caused, which further causes stress concentration at the connection component between the attic steel column and the steel main beam, affecting the service life of the component and increasing the safety risk.

[0003] For the deformation reinforcement and repair of such attic type goods shelf warehouse due to uneven settlement of the floor foundation and the attic column foot, it is difficult to design or construct. There are two existing treatment methods. One is to first remove the attic type goods shelf as a whole, then break the floor structure layer, and then re-pave the cushion layer and pour the floor structure layer to the design elevation for the second time. Or first treat and reinforce the floor foundation, then break the floor structure layer and pour the floor structure layer to the design elevation for the second time. Finally, reinstall the attic goods shelf on the repaired floor elevation. The second method is to first remove the goods shelf structure, then uniformly raise and level the floor structure layer, and finally reinstall the attic type goods shelf structure on the repaired and leveled floor elevation. Both methods require the removal of the attic type goods shelf structure, repair of the deformed floor structure layer, and then reinstallation. The process is complicated, the period is long, the cost is high, and considering the settlement deformation that may occur again in the future, the repair cost is higher and the construction period is longer.
