Between the upper segment steel pipe and the middle part steel pipe and the middle part steel pipe and the lower section steel pipe By steel pipe column flanged joint, steel pipe column flange top is provided with clip, and the top of the clip is provided with supporting plate, described It is provided with the linking beam to support foundation pit horizontally-supported on supporting plate, is provided with gusset on the outside of the clip;
The top of the upper segment steel pipe and concrete linking beam pass through flanged joint.
Preferably, the end face of the gusset and the steel pipe column flange contact, and the welding position of the gusset is staggered institute The connection bolt on steel pipe column flange is stated, the clip is half Snap ring structure, and connects by clamp bolt.
Preferably, the linking beam on the supporting plate is I-shaped structure.
Preferably, the gusset is set as ladder structure of right angle, and is symmetricly set on the two sides of the clip, the clip Internal diameter it is identical as the outer diameter of the upper segment steel pipe, the middle part steel pipe and the lower section steel pipe.
Preferably, the lower section steel pipe and the fender post and floor structure pass through flanged joint.
Preferably, the clip, the gusset and the supporting plate are to be welded to connect.
Therefore, steel pipe column can be recycled in the combined type of the utility model using the above structure, convenient for on-site hoisting, combination connection With dismantle, have bad luck and store, while convenient for be recycled, saved construction cost, reduced construction risk.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that steel pipe column embodiment can be recycled in a kind of combined type of the utility model;
Fig. 2 is the clamping hoop type bracket structure schematic diagram that steel pipe column embodiment can be recycled in a kind of combined type of the utility model.
Specific embodiment
Embodiment
Fig. 1 is the structural schematic diagram that steel pipe column embodiment can be recycled in a kind of combined type of the utility model, and Fig. 2 is that this is practical new The clamping hoop type bracket structure schematic diagram of steel pipe column embodiment can be recycled in a kind of combined type of type.As shown, the utility model provides Steel pipe column can be recycled in a kind of combined type, including the lower section steel pipe 2 being permanently inserted in fender post and floor structure 1 and lower part The middle part steel pipe 3 of the connection of Duan Gangguan 2 and the upper segment steel pipe 4 being connect with middle part steel pipe 3;Upper segment steel pipe 4 and middle part It is connected by steel pipe column flange 5 between steel pipe 3 and middle part steel pipe 3 and lower section steel pipe 2, the setting of 5 top of steel pipe column flange There is clip 6, the top of clip 6 is provided with supporting plate 7, and the linking beam 8 to support foundation pit horizontally-supported is provided on supporting plate 7, blocks The outside of hoop 6 is provided with gusset 9;The top of upper segment steel pipe 4 is connect with concrete linking beam 10 by flange 11, gusset 9 End face is contacted with steel pipe column flange 5, and the welding position of gusset 9 is staggered the connection bolt on steel pipe column flange 5, and clip 6 is half Snap ring structure, and connected by clamp bolt 12, the utility model is convenient for on-site hoisting, combination connection and dismantles, has bad luck and deposits It puts, while convenient for being recycled, having saved construction cost, having reduced construction risk.
