Processing device and method for heavy assembled grouting steel pipe column

Abstract

The invention provides a processing device for a heavy assembled grouting steel pipe column, which comprises a rack, a contoured squeeze board, moving up and down, is arranged on the rack, one side ofthe contoured squeeze board is provided with a limiting squeeze head for pressing a plate to be processed. A feeding trolley is used for transporting the plate to be processed to a bending device from a heating furnace until the end head of the plate to be processed abutts a standard locating part of a locating rod; a charging trolley walks to be above the plate to be processed along the rack, the end head of the plate to be processed is adsorbed and lifted to be flushed with the upper surface of the feeding trolley by a lifting mechanism through a sucking disc, the charging trolley walks tothe position to be processed, the charging trolley and the feeding trolley put down the plate to be processed simultaneously; the limiting squeeze head decreases, a pressing squeeze board tightly presses the plate to be processed, then the contoured squeeze board decreases, and the plate to be processed is pressed and formed; thereby a vertical plate of the heavy assembled grouting steel pipe column is obtained. The processing device provided by the invention can be used for conveniently bending a vertical plate with greater length, and forming a bending section structure with accurate size.

Description

technical field [0001] The invention relates to the field of grouted steel pipes used in high-rise buildings, in particular to a processing device and method for heavy assembled grouted steel pipe laminated columns. Background technique [0002] Existing high-rise buildings require load-bearing columns to have a higher load-bearing capacity, so a prefabricated column that can be grouted in the inner cavity and outer wall of the steel pipe has been developed, and the weight of a single heavy-duty fabricated grouted steel pipe can reach up to ten tons. Existing installation structures such as Figure 10 As shown in , each prefabricated grouted steel pipe is connected by flanges. The problem is that the load-bearing columns of high-rise buildings may also need to bear lateral stress in addition to axial stress, and the flanges are connected by bolts. The connection, the shear strength is weaker, and the lateral force is weaker, so it usually needs to be overcome by increasing t...

Problems solved by technology

Existing installation structures such as Figure 10 As shown in , each prefabricated grouted steel pipe is connected by flanges. The problem is that the load-bearing columns of high-rise buildings may also need to bear lateral stress in addition to axial stress, and the flanges are connected by bolts. connection, weaker shear strength, weaker lateral forces, so usually need to be overcome by increasing the diameter

But this will take up more space in the building interior

[0003] Chinese patent document CN206158011U describes a semi-fabricated ultra-high-strength steel pipe grouting laminated column structure. This scheme adopts the method of on-site welding connection using ring-shaped connecting partitions, but the construction efficiency of this structure is low, especially, the on-site The welding construction conditions are poor, the quality after welding is difficult to guarantee, and potential safety hazards are prone to occur
